Aeroméxico abre tres nuevas rutas directas a los Estados Unidos
Aeroméxico y Delta Air Lines abrirán tres nuevas rutas directas desde Ciudad de México hacia Orange County, Fort Lauderdale y Portland a partir de enero de 2027, con vuelos diarios que ampliarán la conectividad aérea entre México y Estados Unidos.
SN Redacción
Aeroméxico y Delta Air Lines anunciaron el día de hoy la incorporación de tres nuevas rutas para conectar al Aeropuerto Internacional de la Ciudad de México (AICM) con el Aeropuerto John Wayn en Orange County, California (SNA); el Aeropuerto Internacional de Fort Lauderdale-Hollywood en Florida (FLL) y el Aeropuerto Internacional de Portland, Oregón (PDX), fortaleciendo la conectividad entre México y Estados Unidos como parte de su Acuerdo de Colaboración Conjunta (JCA por sus siglas en inglés).
Operadas por Aeroméxico, las tres nuevas rutas comenzarán a partir de enero de 2027 con una frecuencia diaria, a bordo de equipos 737 MAX 8, aeronaves equipadas con un amplio sistema de entretenimiento a bordo y con capacidad para 166 pasajeros: 16 en Clase Premier, 18 en AM Plus y 132 en Cabina Turista.
Con ello, Aeroméxico se convertirá en la única aerolínea en ofrecer vuelos directos entre la Ciudad de México y cada uno de estos tres destinos. Las nuevas rutas ampliarán la red de la alianza Aeroméxico-Delta a 27 destinos en Estados Unidos desde Ciudad de México.
Al respecto Giancarlo Mulinelli, Vicepresidente Senior de Ventas Globales en
Aeroméxico expresó: “Nos complace anunciar tres nuevas rutas hacia los Estados Unidos, uno de los mercados más dinámicos, estratégicos y de alta relevancia para la conectividad internacional de México. La incorporación de estos destinos acerca a nuestros pasajeros a nuevas alternativas para disfrutar de una amplia oferta turística en ambos países, al tiempo que impulsamos la apertura de nuevas oportunidades de negocio e intercambio comercial.”
En conjunto, Orange County, Fort Lauderdale y Portland ofrecerán una amplia variedad de experiencias de placer en Estados Unidos.
Orange County brinda acceso a más de 67 kilómetros de playas sobre la costa del Pacífico, así como a algunos de los parques temáticos más populares de Anaheim, en el sur de California. Desde la esencia artística y las pintorescas playas de Laguna Beach hasta el puerto de Newport Beach y la tradición del surf de Huntington Beach, cada una de las comunidades costeras del condado posee un carácter distintivo, mientras que sus reconocidas zonas comerciales amplían aún más el atractivo del destino.
Por su parte, las playas de Fort Lauderdale, su extensa red de canales y su clima cálido durante todo el año la convierten en una opción ideal para disfrutar de actividades al aire libre. Además, su cercanía con Port Everglades permite a los viajeros complementar fácilmente su itinerario con una estancia en el sur de Florida antes o después de un crucero.
Mientras que Portland combina una reconocida escena gastronómica y un carácter independiente con fácil acceso a la belleza natural del noroeste del Pacífico. Sus cervecerías artesanales y singulares vecindarios se complementan con atractivos cercanos como el río Columbia, el monte Hood y la región vinícola del valle de Willamette.
Los itinerarios y fechas de operación de las nuevas rutas se expresan a continuación:

I'll ask on irc tomorrow if there's a service or something for this, but I'm kinda tired right now and I spent a bit more time than I was wanting to spend.
If anybody ever comes across this, #openbsd #imac , if you remove the HDD on your imac and replace it with a drive that doesn't plug into the temperature probes for the old drive, the SMC will just set the "center mid rear" fan to the max all the time.

¿Sabían que el agua regia fue la sustancia secreta que usaron unos científicos para esconder oro en las narices de los soldados nazis?
Durante la invasión a Dinamarca en la Segunda Guerra Mundial, los oficiales alemanes tenían la orden estricta de confiscar cualquier pieza de valor, incluyendo las medallas de oro del Premio Nobel que los físicos Max von Laue y James Franck habían mandado a guardar en el laboratorio de Niels Bohr. Sacar los pesados discos metálicos del país era imposible porque los fusilarían al instante por traición, así que al químico George de Hevesy se le ocurrió una idea brillante para salvar los galardones sin levantar ninguna sospecha.
Hevesy agarró un frasco de agua regia, una mezcla muy potente de ácido nítrico y ácido clorhídrico inventada en el siglo 8 por el alquimista Jabir ibn Al-Hayyan, y metió las medallas adentro. Ninguno de estos dos ácidos puede hacerle cosquillas al oro si trabajan por separado, pero cuando se juntan, el nítrico rompe la capa exterior del metal mientras el clorhídrico atrapa los pedacitos invisibles, logrando que el material sólido desaparezca por completo en un líquido de color naranja brillante. La Gestapo registró el laboratorio buscando los tesoros de los físicos, pero ignoraron por completo una botella polvorienta llena de líquido ámbar que estuvo guardada a la vista de todos en un estante hasta que terminó la guerra, momento en que los científicos recuperaron el oro del fondo del frasco para volver a fundir las medallas originales.

I let my Claude Ai cut out 15 words from <elou> Emily Campbell's original work, dropping to 201 from 216.
Apple's macOS transcribed her 216 to begin with, but had sometimes said A L in title case to mean A I in uppercase, oops.

I checked out the #iPhone Duo today and I have to say it’s impressive engineering. The crease was imperceptible, I ran my finger over it several times and couldn’t tell there was one. You really would have to look for it. It’s very intuitive to use, but as the end of the day, it’s really just another type of iPhone. It’s a nice touch have but not a must have. For those wanting a foldable iPhone #Apple has a solution for you. For me I’ll use my iPhone 17 Pro Max for a very long time.

I keep my drafts as Markdown files with a short front matter block at the top. It holds the title, a one-line description that ends up as the meta description, and a few tags. When a piece is ready, the static site generator or the blogging platform reads those fields and builds the page from them.
The trouble is that front matter is the part I look at least. I spend hours on the body and about ten seconds on the block above it. So the mistakes pile up there: a title that grew while I was editing and is now far too long for a search result, a description I meant to write later, a tags line I left empty.
None of this is hard to fix. It's just easy to miss. So I wrote a short script that reads every draft in a folder and tells me what's missing or too long.
What it checks
I kept the rules deliberately small:
--- lines.title, description and tags are present and not empty.The two length limits are rough guides, not official numbers. Search engines cut titles and snippets by display width, not by a fixed character count, so treat them as a "probably too long" warning. Change them to whatever your platform or site uses.
A draft that passes looks like this:
---
title: How I name my draft files
description: A simple naming pattern that keeps a folder of drafts easy to search.
tags: [writing, workflow]
---
Body text starts here.
The script
It uses only the standard library, so there's nothing to install.
#!/usr/bin/env python3
"""Flag Markdown drafts with missing or overlong front matter fields."""
import sys
from pathlib import Path
REQUIRED = ["title", "description", "tags"]
MAX_TITLE = 60
MAX_DESCRIPTION = 155
def read_front_matter(text):
lines = text.splitlines()
if not lines or lines[0].strip() != "---":
return None
fields = {}
for line in lines[1:]:
if line.strip() == "---":
return fields
if ":" in line:
key, value = line.split(":", 1)
fields[key.strip()] = value.strip().strip('"').strip("'")
return None # no closing ---
def check(path):
problems =
[] fields = read_front_matter(path.read_text(encoding="utf-8"))
if fields is None:
return ["no front matter block"]
for key in REQUIRED:
if not fields.get(key):
problems.append(f"missing {key}")
title = fields.get("title", "")
if len(title) > MAX_TITLE:
problems.append(f"title is {len(title)} characters (max {MAX_TITLE})")
description = fields.get("description", "")
if len(description) > MAX_DESCRIPTION:
problems.append(
f"description is {len(description)} characters (max {MAX_DESCRIPTION})"
)
return problems
def main():
folder = Path(sys.argv[1] if len(sys.argv) > 1 else ".")
found = 0
for path in sorted(folder.rglob("*.md")):
for problem in check(path):
print(f"{path}: {problem}")
found += 1
sys.exit(1 if found else 0)
if __name__ == "__main__":
main()
read_front_matter returns None when there's no opening --- or no closing one, and a dictionary of fields otherwise. check turns that into a list of plain-language problems. main walks the folder recursively with rglob, prints one line per problem, and exits with status 1 if anything was found.
Running it
Save it as check_front_matter.py and point it at your drafts folder:
python3 check_front_matter.py drafts
With one good file, one file with a long title and no description, and one file without front matter, the output looks like this:
drafts/long-title.md: missing description
drafts/long-title.md: title is 83 characters (max 60)
drafts/no-front-matter.md: no front matter block
Each line starts with the file path, so in most editors' terminals you can click straight through to the file. When everything passes, it prints nothing and exits with 0.
Making it hard to forget
If your drafts live in a git repository, the exit code means you can run the check before every commit. Put this in .git/hooks/pre-commit and make it executable with chmod +x .git/hooks/pre-commit:
#!/bin/sh
python3 check_front_matter.py drafts
If the script finds a problem, git stops the commit and shows the list. When I really do want to commit a half-finished draft, git commit --no-verify skips the hook for that one commit.
I don't always want that level of strictness. On some projects I just run the script by hand before I move a file into the "ready" pile, and that's enough.
What it doesn't do
This is not a real YAML parser. It reads simple key: value lines, one per field. If you write tags as a block list:
tags:
- writing
- workflow
the script sees an empty tags: line and reports it as missing. If that's how you write front matter, either switch to the inline [writing, workflow] style or install PyYAML and use yaml.safe_load on the block instead of the loop.
It also can't tell whether a description is any good. It only knows that one exists and isn't too long. Writing a description that makes someone want to read the piece is still my job. The script just makes sure I don't publish without one.
That's the part I like about small checks like this. They take the boring, forgettable items off my mind, so the attention I have left goes to the writing itself.#python #markdown #writing #productivity #software #coding #development #engineering #inclusive #community

Apple Patches Exploited CoreGraphics Flaw and Hundreds of Vulnerabilities in October 2026 Security Update
On October 26, 2026, Apple released security updates across iOS, iPadOS, macOS, tvOS, watchOS, visionOS and Safari, patching several hundred vulnerabilities concentrated in WebKit, the kernel, ImageIO and CoreStorage. The fixes include WebKit code-execution and sandbox-escape flaws, a Remote Management remote code execution bug, and many privilege-escalation issues, plus the most urgent one: CVE-2026-86950 in CoreGraphics, which was exploited in targeted attacks and makes updating to iOS 18.7.11 critical for owners of older iPhones.
**If you use any Apple device (iPhone, iPad, Mac, Apple Watch, Apple TV or Vision Pro), update it now. The current versions are iOS/iPadOS 27.2, 26.7.2 or 18.7.11, macOS Golden Gate 27.2, Tahoe 26.7.2 or Sequoia 15.8.2, tvOS/watchOS/visionOS 27.2, and Safari 27.2. If you still use an iPhone XS, XS Max or XR, install iOS 18.7.11 first: it fixes a flaw that has been exploited in targeted attacks. Until you've updated, be extra careful about unfamiliar websites, files, images and fonts from strangers, and connecting to unknown file-sharing or Screen Sharing servers.**

Quick Answer
A fleet tracking backend should treat every GPS ping as untrusted input. Sort pings by device time, drop duplicates and impossible values, reject poor fixes and teleport jumps, hold position while a vehicle is parked, and add hysteresis to geofences. Keep the raw stream, store the cleaned stream beside it, and snap to roads only after cleaning. The Python below was tested on synthetic data only, not on live device feeds.
Why does a fleet app receive bad GPS data?
Some of the reasons are written down in vendor documentation. Samsara's vehicle locations documentation says a device reports about every 5 seconds while the vehicle is on and about once an hour while it is off. It also says identical consecutive records can occur, and that GPS interference in a garage can suppress updates even when the vehicle shows as on. The same page says the device keeps a rolling 30 days of location data, so after a connection is restored the buffered points become available through the API.
Read together, those statements describe four problems a backend must expect: duplicate rows, silent gaps, a misleading "on" status, and late data that arrives out of order. This is one vendor's documentation. Other vendors will behave differently, so read the equivalent page for the device you actually use.
What should the ingest layer check before it stores a ping?
My suggestion (author judgement, not a standard) is six cheap checks, run in this order:
The thresholds in the code (50 m accuracy, 45 m/s, 10 m jitter) are starting values I chose for the example. Tune them against your own vehicles and devices.
from dataclasses import dataclass
from math import radians, sin, cos, asin, sqrt
@dataclass(frozen=True)
class Ping:
device: str
ts: int # epoch seconds, device clock
lat: float
lon: float
acc_m: float = 10 # reported horizontal accuracy in metres
def haversine_m(a, b):
r = 6371000.0
p1, p2 = radians(a.lat), radians(b.lat)
dp, dl = p2 - p1, radians(b.lon - a.lon)
h = sin(dp / 2) ** 2 + cos(p1) * cos(p2) * sin(dl / 2) ** 2
return 2 * r * asin(sqrt(h))
def clean(pings, max_acc_m=50, max_speed_ms=45, jitter_m=10):
"""Return a cleaned, time-ordered list for ONE device."""
seen, ordered = set(),
[] for p in sorted(pings, key=lambda p: p.ts): # 1. fix ordering
key = (p.ts, round(p.lat, 6), round(p.lon, 6))
if key in seen: # 2. drop duplicates
continue
seen.add(key)
if not (-90 <= p.lat <= 90 and -180 <= p.lon <= 180): # 3. impossible values
continue
if p.lat == 0 and p.lon == 0: # "null island" fix
continue
if p.acc_m > max_acc_m: # 4. poor fix
continue
ordered.append(p)
out =
[] for p in ordered:
if out:
prev, dt = out[-1], p.ts - out[-1].ts
if dt <= 0:
continue
d = haversine_m(prev, p)
if d / dt > max_speed_ms: # 5. teleport jump
continue
if d < max(jitter_m, p.acc_m): # 6. parked jitter
p = Ping(p.device, p.ts, prev.lat, prev.lon, p.acc_m)
out.append(p)
return out
Testing status: I ran six unit tests with Python 3.13 on synthetic points: out-of-order input, duplicates, 0,0 and poor-accuracy points, a teleport jump, parked jitter, and geofence flapping. All six passed. I have not run this against real device feeds, so treat it as a teaching sample and not production code.
How do you stop geofence alerts from flapping?
A vehicle parked near the edge of a depot boundary can cross it back and forth because of receiver noise, and each crossing can fire an alert. Two techniques help. Use hysteresis, which means the vehicle enters a zone inside radius r but only exits beyond r plus a buffer. Then require several consecutive pings before the state changes.
class Geofence:
"""Circle fence with hysteresis: enter inside r, exit only outside r + buffer."""
def __init__(self, lat, lon, r_m, buffer_m=30, confirm=2):
self.c = Ping("fence", 0, lat, lon)
self.r, self.buf, self.confirm = r_m, buffer_m, confirm
self.inside, self._streak = False, 0
def update(self, p):
d = haversine_m(self.c, p)
want_inside = d <= self.r if not self.inside else d <= self.r + self.buf
if want_inside == self.inside:
self._streak = 0
return None
self._streak += 1
if self._streak >= self.confirm:
self.inside, self._streak = want_inside, 0
return "enter" if self.inside else "exit"
return None
In the test, a sequence of distances of 150, 90, 95, 110, 98, 105, 160 and 170 metres from a 100 m fence produced exactly one enter event and one exit event. Two of those readings (110 m and 105 m) were outside the 100 m radius while the vehicle was still inside the zone, and the buffer absorbed both.
Should you snap points to roads?
Map matching can clean what the filters above leave behind, but it has its own rules. Google's Roads API documentation says one snap-to-roads request accepts up to 100 GPS points and returns points snapped to the most likely road. It recommends keeping consecutive points at or below about 300 metres apart, and offers an optional interpolate setting that adds points following the road shape. Interpolated points have no original index, so the response can contain more points than the request.
OSRM's Match service takes optional timestamps, which must increase, and optional per-point radiuses that default to 5 metres. The documentation suggests using the device's reported accuracy. It returns null for points dropped as outliers and a confidence score from 0 to 1 for each matching. The OSRM page I read was for version 5.5.1, so check the documentation for the version you run.
My judgement: snap after cleaning, keep the raw point and the snapped point side by side, and treat a low confidence score as a flag for review rather than an error.
How do you find vehicles near a depot quickly?
PostGIS documents ST_DWithin as a cheap filter that can use a spatial index, while ST_Distance computes exact distances and cannot use indexes. For geography values the distance is in metres. The common pattern is to filter with ST_DWithin first and sort with ST_Distance on what remains.
SELECT v.id, ST_Distance(v.last_position, d.location) AS metres
FROM vehicles v
JOIN depots d ON d.id = 7
WHERE ST_DWithin(v.last_position, d.location, 2000)
ORDER BY metres;
This query is untested. It assumes both columns are geography with a spatial index on last_position, so check the types and the index in your own schema.
What should the fleet database store?
In my view three tables cover most needs: an append-only table of raw pings, a table of cleaned pings that maps and reports read, and a small table holding the last known position per vehicle for proximity queries. Keeping the raw data lets you re-run a better filter later and settle disputes about a route.
Which are the top five fleet management app development companies?
Teams that prefer to buy this work instead of building it can compare the five partners below. The list is not a ranking of quality.
Figures below come from each company's own website and are self-reported, so confirm them directly before signing anything.
1. Dev Technosys
Dev Technosys is a fleet management app development company with 250+ professionals that does business globally. Its fleet page describes connecting GPS tracking, fuel monitoring and dispatching systems, then automating assignments, maintenance alerts and journey updates. The company builds its own platforms and connects them to existing business systems through APIs instead of configuring third-party ERP products. It states an 89% project success rate and says most new business comes through client referrals; both claims are self-reported. That scope fits teams that already own tracking hardware and need workflow software around it.
2. N-iX
N-iX lists fleet management software development as a dedicated service. Its page covers telematics and predictive-maintenance integration, ELD and IoT sensor integration, hours-of-service compliance modules, route-planning and dispatch engines, and mobile fleet apps. A case study describes a GPS-tracked in-vehicle Linux gateway, a Google Cloud IoT platform and an Android driver app for a telematics client, in a partnership that began in February 2021. The site states over 2,400 software engineers, and the case study gives no fleet outcome figures. N-iX suits teams that need hardware-to-cloud telematics work from one vendor.
3. Intellias
Two fleet case studies sit on the Intellias site. In the first, a Florida telematics client has worked with the company since 2018 on a platform with real-time GPS mapping, idle-time tracking and diagnostic trouble code reporting, and the page says it handles 100,000+ vehicles with data points every 30 seconds. The second is a native iOS, Android and Angular truck-tracking front end for a large car maker, tested on 1,000 vehicles and offered in more than 20 countries. Intellias suits teams that expect high vehicle counts and need a backend built for that volume.
4. Altoros
Altoros says it was founded in 2001 and lists GPS tracking software for car rental, trucking and delivery, fleet management with vehicle tracking and dispatch, and IoT platforms for fleets. Its logistics page cites a transport management case serving 100+ companies and processing 10,000+ automated orders a day, with operator workload cut by up to 70%, plus a truck-parking app prototype covering 10,000+ locations. All of these figures are self-reported, and the page names no ISO certification, so ask for evidence. Altoros suits teams that want an IoT-heavy build from a long-established vendor.
5. STX Next
Describing itself as a Python-native team with more than 20 years of experience, STX Next lists fleet management systems, route optimization, electronic proof of delivery, predictive maintenance and IoT integration on its transport and logistics page. Named case studies include Sendcloud (a carrier integration proof of concept), GS1 Polska (a location-data app for drivers) and T Dispatch (dispatch software). The page mentions Python, IoT, RFID, AWS, Azure and Snowflake and lists delivery centers in Poznan and Merida, but it states no headcount. STX Next suits teams that prefer a Python backend.
FAQ
How often should a fleet device send a position?
Samsara's documentation describes about every 5 seconds while a vehicle is on and about hourly while it is off. Your hardware and data plan set the real figure.
Should raw pings be deleted after cleaning?
In my view, no. Keep them for a retention period your own policy allows, so you can re-run improved filters later.
Do I need map matching in every fleet app?
No. Many dashboards work with cleaned points. Matching helps most when you report distance driven on roads.
What accuracy threshold should I use?
The example uses 50 m as a starting value. Tune it per vehicle type and device.
Can I use this code in production?
It is a teaching sample tested on synthetic data. Add tests built from real device samples first.#python #backend #iot #architecture #software #coding #development #engineering #inclusive #community
Designing a Fleet Tracking Backend That Handles Bad GPS Data
BeeLadybug, my open-source debug overlay, has always shown what's happening in real time: FPS, logs, !important, z-index traps, clicks being swallowed by the wrong element.
The problem is the overlay. Make it big and it covers the game or the page you're debugging. Make it small, the way it is now, and you're squinting at a phone-sized box on the left of the screen while the rows scroll past.
One evening I gave up and asked myself a simple question: why can't I just press a key and get everything on one page, to read calmly?
One key, one file
Version 0.6.1 adds exportReport(). Press F8, or the EXPORT button, and you get report-YYYYMMDD-HHMM.html:
!important, stacking contexts, intercepted clicks, overflow), long tasks, slow resources, Python metricsIt's plain HTML with a dark theme. Ctrl+P turns it into a PDF. You can also get json (for CI or an AI agent) or csv (for a spreadsheet).
import { BeeLadybugCore, exportReport } from 'bee-ladybug';
const bee = new BeeLadybugCore();
// ...attach adapters...
exportReport(bee, { format: 'html' }); // downloads the file
In headless mode (ui: false) nothing is downloaded. The function just returns the data, so it works in Node and in bots too.
How it fits a "blind" Core
The Core still knows nothing about Canvas, the DOM or Python. Each adapter can now register an optional snapshot() hook that returns rows like { severity, selector, rule, value, source }. The exporter asks every registered adapter for its snapshot, and if one throws, it becomes a single warn row while the rest of the report still renders. A new adapter only has to implement snapshot() to show up in the report.
Then I pointed it at real sites
First, my own games portal. It found:
.entry-content creating a stacking context that traps the z-index of the game gridThen, for fun, a big professional games portal. 25 errors, 51 warnings 😄 To be fair, most of them are intentional tricks: negative margins so a carousel can bleed to the edges, and content clipped on purpose inside cards. Their site works great. It still averaged ~52 FPS with 3× my DOM nodes, which taught me more than the error count did.
…and it found bugs in itself
The best part of testing on real pages: the report exposed its own weak spots.
×NAll three are being fixed. A debugger that finds bugs in itself on its first real run felt like a good sign.
Try it
Install it in your project:
npm i bee-ladybug
Or try it right now without installing: open any page, press F12 and paste this in the console, then press F8 for the report.
import('https://cdn.jsdelivr.net/npm/[email protected]/src/index.js')
.then(({ BeeLadybugCore, WebDOMAdapter, CSSAdapter }) => {
const bee = new BeeLadybugCore();
new WebDOMAdapter(bee, { root: document.body }).attach();
new CSSAdapter(bee).attach();
window.bee = bee;
});
Feedback welcome, especially from people debugging Canvas games and DOM-heavy pages.#javascript #webdev #debugging #opensource #software #coding #development #engineering #inclusive #community
I got tired of reading CSS bugs in a tiny overlay, so I made my debugger print a report
Convex Finance (CVX) — Protocol Research Report
By zkscout — Solidity security auditor. Public methodology: aaannvv.github.io/evm-audit-notes. Data: DefiLlama (2026-10-26).
1. Protocol Overview
Convex Finance is a yield-aggregation meta-layer built on top of Curve. Instead of staking Curve LP tokens directly (where rewards depend on each user's veCRV boost), depositors hand LP tokens to Convex, which permanently locks the underlying CRV into its own veCRV position and passes boosted rewards back in simplified form: boosted CRV plus CVX emissions, claimable with no lock. Convex also wraps cvxCRV so CRV stakers retain exit liquidity. Launched May 2021, it became the central instrument of the "Curve Wars" — protocols bid for Convex's veCRV vote weight to direct CRV emissions toward their own pools.
2. TVL Metrics (on-chain, DefiLlama)
The trajectory matters more than the level: Convex peaked at $21.2B in January 2022 and today runs at 3.8% of peak. The decline tracks the general DeFi bear, Curve-specific stress events, and structural share loss to newer venues.
3. CVX Tokenomics
4. Risk Factors
5. Competitive Positioning
Bottom line: a cash-flowing, declining-dominance incumbent. For LPs already in Curve pools it remains the rational boost wrapper. As a token, CVX is levered Curve beta with lock friction — not a standalone growth position.#blockchain #crypto #ethereum #web3 #software #coding #development #engineering #inclusive #community
Convex Finance (CVX) — Protocol Research Report: The Declining Curve Wars Incumbent
Tokens Over Hires
In the middle of September I ran ccusage against every Claude Code session on my laptop since May. It walks the local logs, counts the tokens, and prices them at what the API would have charged. I expected a big number. What came back was about twenty billion tokens and just under fourteen thousand dollars, across every project I’d touched in four months, with most of it going to Pepper, which is now open for signups, so go check it out. Nineteen billion of those tokens were cached reads.
I sat with that for a minute. Fourteen thousand dollars is real money. At my current pace it works out to roughly thirty thousand a year. I could triple it and spend a hundred thousand dollars a year on tokens, and that still isn’t one engineer. In exchange, Chris and I have shipped more code than I’ve shipped in any stretch of my career. I wrote in September that the two of us merged 657 pull requests in our first thirty days with a budget instead of a platform team. When I put the ccusage number in those terms on a panel, it came to about a dollar fifty a pull request.
That number is what my laptop would have cost at API prices, and it isn’t what we actually pay. Here’s the whole bill for both of us. Two Codex subscriptions, one each, are $200 a month. Anthropic is $550 a month: a Max plan for me and Chris, plus two Vycari team seats, one for Chris and one that runs our automation. I have an Ollama subscription at $200 a year. Greptile is about $1,500 a month. All in, that’s a little under $2,300 a month, or about $28,000 a year, for both founders and every pipeline we run. It still isn’t one engineer.
The obvious conclusion is the one a friend reached when he heard the figure: if code is that cheap, just get more tokens. I thought so too, for about a day. Then I looked at what was actually slowing us down, and the token budget wasn’t on the list.
The Constraint Is Attention
Every agent I run needs things from me that tokens can’t buy. It needs a plan approved before it starts. It needs its pull request read when it finishes. When it hits something it can’t decide, it escalates, and somebody has to be there to answer. None of those steps is expensive on its own. The problem is what happens when I run enough agents that the steps overlap.
When I run too many agents, the cost goes up a little and the risk goes up a lot. The biggest thing that’s slipped past us so far was how we managed database connections. It got out of hand, a little at a time, while my attention was on other pull requests, and eventually it caused an outage. Chris had to roll forward while I was out of town, and I spent the following week building a proper database abstraction layer. He put it more bluntly than I would have: the thing that kills us is splitting our attention. That’s when stuff slips through.
When people ask how we decide what to spend, I give them the order. Optimize for human time, because that’s the scarcest thing we have. Then money, because that’s the second scarcest. Then everything around agent time. “I can waste agent time all day. I don’t care.”
So the number that limits us is how many agents one person can supervise well at the same time. I don’t have a precise figure for that ceiling. I know I’ve been over it, because I can feel the difference between a day when every pull request got a real read and a day when I was skimming to keep up.
Another friend told me recently about engineers at his company running up bills in the thousands to build simple internal copies of SaaS tools. His reluctant guess was that they just aren’t as good at using agents yet, and that it’s a skill people have to develop. I don’t know what they’re doing differently. It doesn’t sound like token maxxing, which I’ve never really understood either. I’d love to sit with engineers who run up giant bills and just watch. My guess is they’re using the agents inefficiently, and that what’s missing is supervision, which a bigger budget won’t fix.
Building for More Agents per Person
Almost everything I’ve built since the summer has been an attempt to raise that ceiling, and almost none of it has been about spending less.
The pipeline I described in The Agent That Never Merges is the first piece. Agents open pull requests continuously and never merge them, which means the supervision cost per pull request is bounded at one careful read. The pipeline absorbs the rest: triage, planning, the first round of review comments, the retries. I only see the work once it’s in a state worth my attention.
The second piece is where the work lives. I wrote about pulling Pepper apart into small, bounded repositories to keep CI fast and give agents less to load. It mattered just as much for my attention. An agent working in a repository with one job produces a pull request I can evaluate in one sitting.
We’re up to fourteen repositories now. Last week I moved our iOS app out of the monorepo into its own. That was 150,000 lines of code, and nobody noticed except Chris, who had to wait a day to land his next batch of iOS changes. Agents make refactors that size easy. Having the CLI and the iOS client in their own repositories also forces us to keep good API definitions between the server and its clients.
The third piece is delegation inside the agent layer itself. I run two Claude Opus 5.5 orchestrators on medium effort. One is the UTL, for uber tech lead, and its job is to spawn subagents that build features. The other is what I call the focused worker, and its job is working with me. It catches the manual tasks that come out of the UTL’s pull requests and keeps them in a ledger. Then we work through them together: systems changes, bringing up new platforms, migrating data, anything that needs my level of access and oversight. Everything else goes to a subagent under the UTL, Opus for design docs and code reviews, Sonnet for implementing a feature from a design doc. Every one of these agents can consult a model a tier above it as an advisor, and they all share a wiki for notes.
Anthropic is now advertising much the same pattern with Claude Projects, and I’m happy to see others arriving at the same answer. Chris has been building a loop that babysits open pull requests through review until they score well enough to be worth a human’s time. Each layer like that turns a job I used to do by hand into something I check. The ceiling goes up one delegated task at a time.
The Token Budget Was the Easy Problem
There was a week in September when the meter really was the constraint. We ran through our free credits and paid about $120 in overage. Then AutoDev ate the whole Vycari quota, and I did server cleanup by hand because I couldn’t do anything else.
Most of that was self-inflicted. I’d started with Fable as the orchestrator, with no cap on context, and burned a week’s quota in three days. The setup above fixed it. The orchestrators run on medium effort, and the cheaper model does the implementing. Opus answers the reviews because Sonnet is too literal about them, and a literal reading turns two review cycles into twelve. Every agent auto-compacts at 200K tokens, because Anthropic charges more for context past that point. With that setup, and the work spread across parallel sessions, I find it hard to spend all of my quota. My goal now is to hit 99% of it every week just before it resets. I keep a list of research projects, and if I have quota left 24 hours before the reset, I spin one up. That isn’t the same as maxing out tokens. I’m not trying to use as many as possible. I’m trying to use all the ones I’ve already paid for.
There’s also a second account on the same machine. Claude Code reads a CLAUDE_CONFIG_DIR environment variable, so two shells with two config directories give you two accounts side by side. The second one runs the AutoDev and code review pipelines, and those use up its quota every week, so it isn’t a fallback for my own sessions. When I do run short, I supplement with other labs’ plans. Every one of those fixes took an afternoon or less. None of the supervision problems above has had an afternoon fix.
Where the Money Actually Goes
While I had the numbers in front of me, I looked at where development spend actually lands, because it isn’t where I expected either.
Development tokens currently run about ten times what the product itself consumes, even with real people using it. Building the thing costs more than running it. That won’t last. The feedback from our private beta has been really good, and we now open Pepper to a limited number of new signups every day, so product usage is rising quickly.
Most of what we actually pay goes to code review. Subscriptions are the cheap way to buy tokens if you’re willing to hit limits, so they’re the smaller line. Greptile reviews every pull request we open, and at about $1,500 a month it’s our biggest single expense. We both think it’s worth it, because it’s the layer that lets the never-merge pipeline run without me reading every first draft.
In October I tested that. I spent a few days building a cheaper reviewer to replace it. I came out the other side saying, “I think we should just pay for it because I can’t do it cheaper.” What I could change was how often we call it. The agents kept asking for a re-review before they’d fixed anything. Because every repository shares a common dev environment, the fix went in once: our pull-request skill now has agents run /simplify and then /code-review before they’re allowed to open a pull request. On many of our repositories, our own reviewer also does the first round and only then calls Greptile. My goal is a pipeline where Greptile’s reviews come back with nothing to say. We’re not there yet, but we get a little better every week.
I’d rather pay for review than have a second person do it, and the reason isn’t salary. The person would need supervising too, because review is a job I’d have to check, not one I can hand off.
What a Hire Is For Now
Five years ago, if I’d been getting a product like this ready for market, I’d have been hiring twenty to fifty engineers. The work would have needed that many hands, and most of what they’d have done was write code. Today the code is the cheap part. If I bring someone in to write code, I’ve added a person who needs plans approved and pull requests read, which is the exact resource I’m short on. A hire whose job is output adds coordination faster than it adds capacity.
I said on a podcast that came out last week that the code I’ve written would have cost about fifteen thousand dollars at API prices, and that I couldn’t hire engineers for that money. That’s true. The engineers I’d still want are a different kind from the ones I hired at Google. We need a few more people who can herd agents, not fifty.
The engineering hire that adds capacity is a different shape. It’s someone who can own a bounded service whole. Here’s the interface, here’s everything it needs to do, let me know when it’s done. That person brings their own supervision. They run their own agents, read their own pull requests, and answer their own escalations, and the only thing that crosses the boundary between us is the contract. Supervision divides along the interface instead of piling up on one person. That’s a tech lead’s job, and it’s the only kind of engineering hire I can see that raises the ceiling instead of lengthening the queue.
That raises a fair question about how anyone grows into that job now, which I tried to answer in The Questions Are the Job. The other advice I give is to work on open source. I’ve met people who showed they could work really efficiently with agents through open source projects, Gemini CLI in particular, and some of them ended up being hired onto my teams. Open source has its own problems right now. But if you show up as a thoughtful engineer with features or bug fixes that are well reviewed, well tested, and bring value to the project, I think you’ll be welcome. That’s one of the reasons I decided to open source the Pepper CLI.
The first hire probably isn’t an engineer at all. I’ve said this a few times now, including on stage at a panel in September. Neither Chris nor I are go-to-market people, and I may hire one before I hire another engineer. I can create piles and piles of code, even relatively good code. What I can’t do is agentically acquire customers. (Did I mention that Pepper is open for signups now?) Someone in marketing came up after the panel and told me I’d validated her existence.
The Third Trend
I’ve watched this happen twice before. Open source developer tooling made it so a small team didn’t need to buy or build its own compilers, databases, and frameworks. Cloud infrastructure made it so that team didn’t need to own hardware or a data center. Each time, the number of people you needed to start something real dropped, and the skills that mattered shifted toward the people who understood systems well enough to compose what was suddenly free.
Agentic tools are the third one. Anyone with a good idea can now get from concept to production on a budget that would have been a rounding error in a Google planning cycle. But the constraint didn’t vanish. It moved, the same way it did the last two times, toward the people who understand systems design well enough to drive the agents and notice when something has slipped through. I wrote a year ago that management skills were going to carry over to working with agents. I didn’t expect to be proving it with a two-person org chart and fourteen thousand dollars of tokens.
This isn’t only a small-company problem. At Google it was hard to get more than a few changes in a day, because each one waited on code review. I’ve talked to engineers there who now do all their work in experimental directories that don’t require review, then port it back to their team’s repository at a pace the review process can keep up with. That’s what happens when you don’t manage for human attention. Productive people spend their cycles waiting on the process.
When other companies ask me what to change, my answer has become: drive until human attention is the scarce resource, then build for that. If you’re reading your own ccusage number and wondering whether the answer is more tokens, look at where your attention went first. For us the answer has been more interfaces. Those are the places where one person’s supervision ends and another’s begins, or where an agent takes over a job one of us used to do by hand.

Your Python code works. It’s also slower than it needs to be. 🐢
If you work in AI or data, you’ve probably lived this loop:
Prototype in Python because it’s fast to write.
Hit a performance wall.
Rewrite the hot paths in C++, Rust, or CUDA.
Now you maintain two languages, two toolchains, and a fragile bridge between them.
This is often called the two-language problem. It costs teams time, hiring flexibility, and a lot of debugging hours. Mojo is an attempt to fix it at the root.
What is Mojo?
Mojo was created by Modular, co-founded by Chris Lattner, who also created Swift and LLVM. It combines Python-like syntax with systems-level performance and memory safety ideas inspired by Rust, and it uses the MLIR compiler framework to target hardware such as GPUs, CPUs, TPUs, and ASICs.
opensourceforu
The goal is simple: one language from prototype to production, with code that looks familiar to Python developers.
Why 1.0 matters
For years, Mojo was a fast-moving experiment, and its syntax changed often. That made it hard to bet a real project on it.
Version 1.0 brings backward compatibility and API stability, and future 1.x releases are expected to be mostly additive. Modular also says it relies on Mojo daily in production, as the foundation of its own commercial products, MAX and Modular Cloud.
opensourceforu
modular
In short, the language you learn today shouldn’t break under you next month.
What problems does it solve?
You write code that reads like Python, but you get control over types, memory, and hardware when you need it. You don’t have to jump to a different language for the hot path.
Instead of Python for the model and C++ or CUDA for the kernels, you can aim to write both in the same language. That means a smaller skill gap inside your team.
AI workloads now run on many kinds of accelerators. Because Mojo is built on MLIR, it is designed to target different hardware without rewriting everything per vendor.
You don’t need to migrate your whole codebase. Mojo is designed to work alongside Python, so you can start with the one function that’s too slow.
A first look at the code
Here is a simple example. It looks like Python, which is the point:
mojo
def main():
var total = 0
for i in range(1_000_000):
total += i
print(total)
The real gains show up when you add static types and use Mojo’s low-level features for performance-critical sections. Check the official Mojo docs for the current syntax, since the language was cleaned up significantly for 1.0.
Where to be realistic
I don’t want this to read like hype, so here are the caveats:
The ecosystem is young. Python has decades of libraries. Mojo does not, and you’ll often lean on Python interop.
It’s strongest for AI and performance-heavy work. For a typical CRUD web app, Python or Go is still the simpler choice.
Governance is worth watching. Modular was acquired by Qualcomm in mid-2026, and open-source status and community direction are things to keep an eye on as the ecosystem grows.
opensourceforu
Features are still arriving. Async programming, pattern matching, and tagged unions are on the roadmap.
opensourceforu
Should you try it?
My take:
Yes, if you work on ML, GPU kernels, or numerical code and you’re tired of maintaining a Python and C++ split.
Maybe later, if your workload is mostly I/O-bound or web-focused.
Worth a weekend, if you just want to see where language design is heading.
Getting started
Read the official Mojo documentation.
Install the toolchain and run a small benchmark of your own slow Python function.
Port just that one function and measure the difference.
Measure on your own workload. Benchmarks from other people’s projects won’t tell you whether it helps yours.
Final thoughts
The two-language problem has been accepted as “just how things are” for a long time. Mojo 1.0 doesn’t magically end it, but it’s the first time the idea feels stable enough to try seriously.

Mojo 1.0 Is Here: Is the Two-Language Problem Finally Over?
This week, the open-source community buzzed with updates on model serving infrastructure, including the latest PRs for vLLM-Omni support. As teams race to deploy more efficient and scalable inference pipelines, one often-overlooked piece of the puzzle remains: ensuring that the hardware is ready before the job even starts. At Apex Grid, we’ve spent the last few months refining a two-stage GPU preflight check that has become a critical part of our cron agent infrastructure.
When deploying cron jobs that depend on GPU resources, it’s not enough to simply wrap the job in a try/except block. That approach risks silently failing when the underlying issue is not the job itself, but the state of the GPU. For example, another job might be monopolizing the card, or the kernel might be in a state where it’s not responding to requests. Our solution involves a two-stage preflight check that ensures both the GPU and the serving stack are in a healthy state before we even attempt to run the job.
Our preflight logic hinges on two simple but effective endpoints: one that checks for basic health (/api/tags) and another that performs a lightweight inference (/api/generate). The first check ensures that the model server is responsive and can return a list of available tags - a quick smoke test. The second check runs a minimal inference task, which helps us detect if the GPU is actually available and not being blocked by another job. We set a warmup timeout for this second check, typically between 3 and 10 seconds, depending on the model size and workload.
Here’s how our gpu_ready() helper looks in practice:
import requests
import time
def gpu_ready(base_url, warmup_timeout=5):
# First check: basic health
try:
tags_response = requests.get(f"{base_url}/api/tags", timeout=3)
if tags_response.status_code != 200:
return False
except requests.exceptions.RequestException:
return False
# Second check: warmup inference
try:
generate_response = requests.post(
f"{base_url}/api/generate",
json={"prompt": "Hello, world!", "max_tokens": 1},
timeout=warmup_timeout
)
if generate_response.status_code != 200:
return False
except requests.exceptions.RequestException:
return False
return True
This approach has several advantages. It ensures that the GPU is not just available but also in a state where it can handle the job without stalling or timing out. It also allows us to cleanly skip the job if the preflight check fails, rather than letting it fail later and potentially leaving the system in an inconsistent state. This has been particularly useful in environments where multiple cron jobs share the same GPU resource pool.
Of course, there are tradeoffs. The preflight check adds a small amount of latency to the overall job scheduling process. Additionally, it requires that the model server exposes both the /api/tags and /api/generate endpoints, which may not be the case for all serving stacks. We’ve mitigated this by making the preflight logic configurable - allowing teams to skip the second stage if needed, or to use a different lightweight inference task.
Looking ahead, we’re exploring ways to make this preflight logic more adaptive. For example, we’re experimenting with using a lightweight model for the warmup inference that’s specifically tuned for this task, reducing the time it takes to complete the second stage. We’re also looking into integrating this logic more deeply with Kubernetes and other orchestration tools, to make GPU readiness checks part of the broader system health monitoring pipeline. What do you think - would you prefer a preflight check that’s even more lightweight, or one that gives more detailed diagnostics when it fails?#python #devops #ai #reliability #software #coding #development #engineering #inclusive #community

Governance Attack Surface Review: Polygon Bridge
Target Protocol: Polygon Bridge (TVL: $2660.5M)
Governance Attack Surface Review – Polygon Bridge
Protocol: Polygon Bridge (Ethereum ↔ Polygon PoS)
TVL (approx.): $2.66 B (Ethereum + Polygon L2)
Date: 25 Oct 2026
Prepared by: Senior DeFi Security Researcher – Independent Audit
1. Executive Summary
The Polygon Bridge is the primary trust‑minimized conduit for moving ERC‑20, ERC‑721, and ERC‑1155 assets between Ethereum mainnet and Polygon PoS. While the bridge’s core token‑locking contracts have been extensively audited and are widely regarded as secure, the governance layer that controls upgrades, fee parameters, and emergency pausing introduces a non‑trivial attack surface.
Our review focuses on the governance contracts, timelock mechanisms, role‑based access control, and the interaction between governance and the bridge’s core contracts. We identified several high‑impact vectors that could allow an adversary—either a malicious proposer, a compromised multisig, or a colluding validator set—to:
Overall, the governance attack surface scores 7 / 10 on a 1‑10 risk scale (1 = negligible, 10 = critical). The most severe risk stems from insufficient separation between upgrade authority and operational controls, combined with low‑entropy timelock parameters that could be rushed under a “fast‑track” proposal path.
The remainder of this report details each identified vector, quantifies its impact, and provides prioritized, actionable remediation recommendations.
2. Identified Attack Vectors
#VectorDescriptionPotential ImpactLikelihoodCurrent MitigationsExploitability (CWE)1Upgrade Authority CentralisationThePolygonBridgeProxy points to an implementation contract that can be upgraded by a single Polygon DAO Multisig (3‑of‑5). The multisig’s owners are partially composed of core Polygon team members and a few external partners.Full control over bridge logic → arbitrary token mint/burn, fund diversion, disabling withdrawals.Medium‑High (social engineering, key‑compromise).Multisig threshold, time‑locked execution (48 h).CWE‑250 (Execution with Unnecessary Privileges)2Fast‑Track Governance PathA “fast‑track” proposal (used for urgent patches) reduces the timelock from 48 h to 6 h and requires only 2‑of‑5 signatures. The fast‑track can be triggered by any proposer with a “priority” flag.Allows rapid deployment of malicious code before community can react.Medium (requires collusion or compromised proposer).Limited to “critical” proposals (subjective).CWE‑284 (Improper Access Control)3Fee & Withdrawal Limit ManipulationGovernance can modify withdrawalCap, dailyLimit, and bridgeFee. By setting caps to zero or fees to 100 %, the bridge can be rendered unusable or cause a “run” where users rush to withdraw before caps are lowered.Economic denial‑of‑service, loss of user confidence, potential liquidity crunch on Polygon.Medium (requires governance action).Caps are bounded by hard‑coded max values; however, bounds are generous.CWE‑352 (Cross‑Site Request Forgery) – analogous to “parameter tampering”.4Emergency Pause AbuseThe pauseBridge() function can be called by the Governor (single address) without timelock. Pausing halts deposits/withdrawals but does not unlock already‑locked assets.Market manipulation, forced migration to competitor bridges, potential “bridge‑freeze” attack.Low‑Medium (single‑key compromise).Governor address is a contract that forwards calls from the DAO; no delay.CWE‑276 (Improper Restriction of Excessive Authentication).5Cross‑Chain Message ReplayThe bridge uses a Merkle‑root based proof system for withdrawals. The proof verification contract does not store a per‑nonce replay bitmap for ERC‑721/1155 tokens, relying only on token‑ID uniqueness.An attacker could replay a withdrawal proof for an NFT that was transferred multiple times, resulting in double‑spend.Low (requires precise timing & knowledge of state).ERC‑721/1155 withdrawals include a nonce but the bitmap is cleared only on contract upgrade.CWE‑284 (Improper Access Control)6Governance Parameter Race ConditionThe setValidatorSet function (used to update the set of PoS validators that sign exit proofs) can be called in the same block as a withdrawal proof that relies on the previous validator set.A malicious validator could approve a fraudulent exit before the new set is activated, stealing assets.Low‑Medium (depends on block ordering).Validator set changes are delayed by 1 hour, but no explicit finality check.CWE‑362 (Race Condition)7Insufficient Event Logging for Governance ActionsCertain governance actions (e.g., fee changes) emit only generic ParameterChanged events without the new value or caller address.Reduces transparency, hampers on‑chain monitoring and off‑chain alerting.Low (operational risk).None.CWE‑778 (Insufficient Logging).8Upgradeable Proxy Storage CollisionThe proxy uses the unstructured storage pattern, but a future implementation could unintentionally overwrite critical storage slots (e.g., owner, timelock).Loss of control, accidental self‑destruct, or forced upgrade to a malicious contract.Low (requires malicious upgrade).Storage slot constants are documented; no automated slot‑collision checks.CWE‑124 (Improper Protection of Critical Data).2.1 Deep‑Dive on the Highest‑Risk Vectors
Vector 1 – Upgrade Authority Centralisation

The DAO’s governance token (MATIC) voting power is heavily weighted toward the Polygon core team (≈ 55 %).sweep() function.

5. Conclusion
The Polygon Bridge remains a cornerstone of Ethereum‑Polygon interoperability, handling billions of dollars in assets. Its core token‑locking contracts are robust, but the governance layer introduces a concentration of power and procedural shortcuts that could be exploited to compromise the entire bridge.
Our analysis shows that the most exploitable weakness is the ability to upgrade the bridge implementation with a relatively low‑threshold multisig and a fast‑track path that bypasses community scrutiny.

Governance Attack Surface Review: Polygon Bridge
Meta's personal AI agent, Muse, launched in Japan on October 23, 2026 — its first market outside North America.
That one sentence matters more than it looks. A month ago, the proactive-agent race was an American story. Now it has a second country, a second language market, and a clear signal about where this contest is actually fought: not just on model quality, but on distribution geography and connectors.
What launched in Japan
Muse debuted in the US and Canada in September. Japan is the first expansion beyond North America, and it arrives on all three surfaces that matter: iOS, Android, and the web. Basic functions are free, with subscriptions unlocking more.
That is the shape of the whole category right now. Free to try, paid to go further, and rolling out country by country rather than everywhere at once. If you are building anything that plugs into these agents, the rollout map is your roadmap — your users in Tokyo just joined your users in Toronto.
The field, in one sweep
Muse did not land in an empty market. Within the last few weeks, every major lab has put its own proactive agent on the board:
Anthropic's Claude Duet opened as a research preview on October 21, 2026. It is waitlisted, limited to US Pro and Max subscribers for now, built on Claude Opus 5.5, and it leans hard on connections: more than 6,000 connectors, a morning brief, and — the detail developers should steal — it asks before it sends, pays, or deletes anything.
OpenAI's Dots launched in late September for ChatGPT Pro and Business Premium users, bringing proactive, multi-step work to the largest existing chatbot audience.
xAI's Grok Bot has been out since August 11, built around multi-agent teams rather than a single assistant doing everything.
Four labs, four agents, four different bets. And one shared pattern: none of them is simply open to everyone yet.
Why this is about geography and connectors now
Here is the honest read, based on the announcements and coverage rather than hands-on testing: the models are no longer the differentiator. Every lab has a strong model. What differs is who can reach users, where, and what the agent can actually touch once it gets there.
Japan is Meta's answer to the reach question. Duet's 6,000-plus connectors are Anthropic's answer to the touch question. Dots' bet is that the ChatGPT audience itself is the distribution. Grok Bot's bet is that teams of agents beat one generalist.
For developers, that reframes the work. The winning integration is probably not "support the smartest agent." It is "support the agent your users already have, in the country they live in, with the tools they already use" — and design your permission model like Duet does, where the agent checks before it does anything irreversible.
That last point deserves emphasis, because it is where this whole category will win or lose trust. An agent that sends, pays, or deletes without asking is a liability with a nice voice. An agent that asks first is a colleague. Duet's rule — ask before send, pay, or delete — should be the default every developer demands from every agent they build on, regardless of which lab wins.
The honest catch
Every one of these agents is still gated. Muse is in three countries. Duet is waitlisted and limited to US Pro and Max subscribers. Dots sits behind Pro and Business Premium plans. Grok Bot aside, "proactive AI for everyone" is a headline, not a reality — yet.
So do not rebuild your product around any single agent this week. Build the connector layer once, keep the permission checkpoints yours rather than the agent's, and watch the rollout maps. The lab that reaches your users' country with the connectors your product needs will pick your winner for you.
What to watch next
Three things, in order. First, which country Muse enters next — the pace of that map tells you how fast Meta thinks it can scale this. Second, whether Duet's waitlist opens wider, and whether its connector count becomes the number every rival has to match. Third, whether any lab drops the gating entirely and goes for raw reach. The first one to do that changes the race overnight.
The agent war went global this week. It just has not gone universal yet — and that gap is where developers still have time to get ready.
Based on the announcements and coverage: MacRumors (October 21, 2026) on Claude Duet, GenZ NewZ (October 24, 2026) on Muse in Japan, and AI Stack Crunch (October 23, 2026) on the wider agent roundup. No hands-on testing is claimed in this article.

Meta's Muse Just Landed in Japan — and the Proactive Agent War Just Went Global
You open the repo on your first morning, the README says "run the app, ask it something," and forty seconds later an answer appears on the phone. Nobody on the team can tell you whether that text came from the bundled on-device model, from a remote endpoint someone configured last quarter, or from a fixture left in a debug build. That uncertainty is not a small onboarding annoyance, because every later measurement you record inherits it.
This post is a first-hour exercise for a junior engineer joining a mobile AI repo. The goal is not to ship a feature, and it is not to improve latency or accuracy; the goal is to make provenance visible, so that when you do open your first PR you already know which execution path you exercised. Everything below is a proposed harness that you run on your own device, not a report of numbers I measured on yours.
Why provenance belongs in hour one
In a normal backend repo you can read the config and know which database answered. In a mobile AI repo the same request can be served by three different things depending on build type, network state, and whether an asset survived the packaging step. If you skip this check, you will eventually write a careful benchmark, show it to your reviewer, and discover the phone was calling a cached response the whole time.
The exercise below gives you three things you can rely on for the rest of onboarding: a build that fails loudly when the model asset is missing, a debug banner that names the source of the last response, and a repeatable way to exercise the remote path on purpose.
The three sources to distinguish
Your banner only needs to name which of these produced the last result. It does not need to be pretty, and it should not ship in release builds.
Step 1: make a missing model asset a build failure
Before you touch any inference code, prove that the file you think is packaged actually is. Add a verification task to the app module and wire it into the check lifecycle. Substitute your own asset name and the checksum your team stores alongside the artifact.
// app/build.gradle.kts (proposed harness)
val modelDir = layout.projectDirectory.dir("src/main/assets/models")
// Placeholder on purpose: copy the real digest from your artifact record.
val expectedDigests = mapOf(
"classifier-small.tflite" to "<sha256-from-your-artifact-record>"
)
tasks.register("verifyModelAssets") {
val dir = modelDir
inputs.dir(dir)
doLast {
expectedDigests.forEach { (name, want) ->
val file = dir.file(name).asFile
require(file.exists()) { "Missing model asset: $name" }
val got = java.security.MessageDigest.getInstance("SHA-256")
.digest(file.readBytes())
.joinToString("") { "%02x".format(it) }
require(got == want) { "Checksum mismatch for $name\nexpected=$want\n got=$got" }
}
println("verifyModelAssets: OK")
}
}
tasks.named("preBuild") { dependsOn("verifyModelAssets") }
Expected observation on a healthy checkout is a single verifyModelAssets: OK line before compilation. Then deliberately rename the asset once, run ./gradlew :app:assembleDebug, and confirm the build stops with the message you wrote. If it compiles anyway, your app has a runtime download path you have not found yet, and that is the most important thing you will learn all day.
Step 2: print the source of the last response
A tiny recorder next to your inference entry point costs almost nothing and removes the guessing. Keep it debug-only, and never log prompt text or user content in it.
// Proposed harness. Field names follow your app's existing types.
sealed interface ModelSource {
data class Bundled(val asset: String, val digestPrefix: String) : ModelSource
data class Remote(val host: String, val path: String) : ModelSource
data class Fixture(val name: String) : ModelSource
}
object Provenance {
private val seen = ArrayDeque<ModelSource>()
fun record(source: ModelSource) {
seen.addLast(source)
if (seen.size > 20) seen.removeFirst()
if (BuildConfig.DEBUG) Log.d("Provenance", describe(source))
}
fun last(): ModelSource? = seen.lastOrNull()
private fun describe(s: ModelSource): String = when (s) {
is ModelSource.Bundled -> "bundled ${s.asset} sha256:${s.digestPrefix}"
is ModelSource.Remote -> "remote ${s.host}${s.path}"
is ModelSource.Fixture -> "fixture ${s.name}"
}
}
Call Provenance.record(...) exactly where the response is produced, not where the request is built, because a retry can change the answer's origin. If you use Compose, a two-line debug overlay reading Provenance.last() is enough; on iOS the same idea maps to a #if DEBUG view or an os_log line.
What the banner buys you
Step 3: exercise the remote path deliberately
Many teams use a hosted endpoint for early integration work, and some projects offer free model access plus a free server option so a new contributor can get a working call without a billing conversation. The open-source project MonkeyCode is one of these, and its operator describes a free model-access tier and a free server option for trying the workflow; the same operator-supplied description puts the free allowance at 10 million tokens. Treat that figure as a starting point, not a contract, and re-read the project's current terms before you plan any budget around it.
Disclosure: This article was prepared as part of MonkeyCode's product outreach.
The useful part for onboarding is narrower than the marketing: a shared free endpoint lets you prove that your client's request shape, timeout, and error handling work before you depend on a host only three people can reach. Time the first call rather than trusting it.
# Shape only. Use the base URL and path from the project's own setup docs.
BASE_URL="https://<your-endpoint-from-the-project-docs>"
for i in 1 2 3; do
curl -sS -o /dev/null \
-w "attempt=%{http_code} ttfb=%{time_starttransfer}s total=%{time_total}s\n" \
-H "Content-Type: application/json" \
-d '{"prompt":"ping","max_tokens":8}' \
"$BASE_URL/v1/complete"
done
Record three numbers per attempt and note whether the first one is slower than the rest, which would suggest a cold path rather than a steady one. Do not run a load test against shared free infrastructure; three sequential calls teach you what a first-hour contributor needs, and concurrency experiments belong on a host your team controls.
When the banner disagrees with your mental model
SymptomLikely broken pathFirst checkBuild passes with the asset deletedSilent download or remote fallbackGrep for the model URL in build configBanner saysremote in airplane modeCached response or fixtureClear app storage, rerunBanner says bundled but answers varyPrompt template changedDiff template file against mainFirst remote call takes much longerCold endpoint or cold radioRepeat three times, note radio stateWorks after reinstall onlyAsset copied at first launchInspect first-run copy logic
Each row is a rollback condition, not a curiosity. If your banner reports remote while the device has no network, you have found something worth raising before you write feature code.
Evidence to record before your first PR
Fill this in on your own hardware and paste it into the PR description or your onboarding notes. Reviewers trust a filled table far more than a sentence claiming it works.
Limitations and who should skip this
This harness assumes your app can load a model from local storage. If your product is server-only inference, a bundled-asset check adds noise and you should stop after step 2 and document the endpoint instead. Teams with a managed model registry may already enforce digests in CI, in which case duplicating the check locally is waste. Checksumming a multi-hundred-megabyte asset on every build slows feedback loops noticeably, so scope the task to debug variants or run it on a schedule.
Finally, the banner is diagnostic tooling. It must be stripped or gated in release builds, because hostnames and asset digests are information you gain nothing from publishing.
If you run this in your own repo, I would like to see the environment rather than the conclusion: device, OS, framework versions, the transition steps you used, and whether the banner recovered, restarted, or silently disappeared.

Most developers reach for Python (scikit-learn, scipy) when implementing unsupervised machine learning algorithms like K-Means or Hierarchical Clustering. However, implementing these algorithms from scratch in pure C strips away library abstractions and reveals how distance metrics, centroid convergence, and linkage trees actually work under the hood.
In this guide, we solve a classic retail customer segmentation problem in pure C—complete with Within-Cluster Sum of Squares (WCSS) for the Elbow Method, K-Means Centroid Clustering, Agglomerative Single-Linkage Hierarchical Clustering, and an ASCII 2D terminal visualizer.
The Problem Statement
A retail company wants to segment its customers based on:
Our goal is to:
The Dataset
We use a clean 6-customer dataset so you can trace every single Euclidean distance calculation by hand and verify the C output directly:
Mathematical Foundations
1. Euclidean Distance
Both K-Means and Single-Linkage Hierarchical Clustering measure similarity between two points $P_1(x_1, y_1)$ and $P_2(x_2, y_2)$ using straight-line Euclidean distance:
$$d(P_1, P_2) = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$
2. The Elbow Method & WCSS
The Elbow Method finds the optimal number of clusters $K$ by calculating the Within-Cluster Sum of Squares (WCSS) across increasing values of $K$:
$$\text{WCSS} = \sum_{i=1}^{K} \sum_{x_j \in C_i} \left( (x_j - c_{ix})^2 + (y_j - c_{iy})^2 \right)$$
Because the sharpest drop ("elbow") occurs at $K = 2$, the optimal number of customer segments is 2.
Version 1: Minimal & Clean Implementation (exam_clustering.c)
If you want a concise, flat implementation using simple 1D arrays without struct overhead—ideal for quick prototyping, university lab exams, or understanding the core loops—here is the streamlined version:

Implementing K-Means & Hierarchical Clustering in Pure C for Customer Segmentation
I wired up a free model endpoint last month. I sent one request. It returned 200 OK. I shipped the feature. Then the tool calls never happened. The endpoint accepted the request. It just ignored half of it. Sound familiar?
Here is my question. What does a 200 actually prove? My answer: almost nothing about capabilities. It proves the transport worked. That is it.
So I stopped trusting status codes and started probing the contract. This post is the FAQ I wish I had read first. It ends with a script you can run in about two minutes.
Myth 1: A 200 means the model supports my feature
The server can accept a tools array and silently ignore it. The model then answers in prose. No error. No warning. Your code sees a normal response and skips the branch. Is that a bug in the model? No. It is a bug in your assumption.
The corrected model: support is a property of the endpoint, not of the model name. Probe it. Record it. Re-probe when anything changes.
Myth 2: finish_reason is optional metadata
It is the most important field in the response. length means the model ran out of output budget. Your answer looks fine and is probably cut in half. I have watched a parser happily eat a truncated JSON object.
{"choices":[{"finish_reason":"length","message":{"content":"{\"items\": [1, 2, 3, 4"}}]}
If you do not branch on finish_reason, you are parsing whatever bytes arrived. That is not a feature. That is a coin flip.
Myth 3: Streaming and non-streaming are interchangeable
They are two different code paths. In streaming, finish_reason arrives in the final chunk, not the first. Some servers only report token usage when you ask for it explicitly. Some omit it entirely.
Ask yourself: does my client read the last event? Mine did not, for a week. I was logging None as the finish reason every single time.
Myth 4: JSON mode means my schema
It means valid JSON. It does not mean your keys. It does not mean your types. Validate every response against a schema before it touches business logic. Treat model output like user input, because that is what it is.
Myth 5: Retries are always safe
Retry a failed read, fine. Retry a tool call that already wrote a row, and now you have two rows. I learned this from a duplicate charge, not a blog post.
Add an idempotency key your tool honors. Make the retry decision depend on the operation, not on the exception class.
The artifact: a five-minute capability probe
This script uses only the Python standard library. It assumes a chat-completions-shaped endpoint. Adjust the paths if yours differs.

I run probes from a throwaway box, not my laptop. Same reason I do not test migrations on my main database. The probe should not touch anything I care about.
MonkeyCode's free model access and free server option are the two pieces I use for that. The free model access gives the probe something to talk to. The free server option gives it a disposable place to run. Disclosure: This article was prepared as part of MonkeyCode's product outreach.
I am not claiming the free tier is fast, generous, or permanent. I do not know its limits, and I am not going to guess at them. Run the concurrency probe and read your own numbers. That is the whole point of this post.
Limitations and who should skip this
Skip this approach if you need contractual latency SLOs, deterministic output, or guaranteed tool-call behavior. Buy a plan with a written contract. A probe will not save you from a missing SLA.
The corrected mental model
Treat every free endpoint as a set of separate promises. Transport, truncation, tool calls, JSON shape, and concurrency are five different promises. A 200 only confirms the first one.
Which promise broke on your last integration? I keep a one-page probe log per endpoint now. It has saved me two weekends so far.#ai #api #testing #python #software #coding #development #engineering #inclusive #community

Smart Contract Vulnerability Surface Analysis: Compound V3
Target Protocol: Compound V3 (TVL: $1372.5M)
Smart Contract Vulnerability Surface Analysis
Compound V3 (Ethereum & L2s) – $1.372 B TVL
Prepared by: [Your Firm] – Senior DeFi Security Research & Auditing Team
Date: 25 Oct 2026
1. Executive Summary
Compound V3 is the latest iteration of the flagship money‑market protocol, introducing isolated risk markets, dynamic supply caps, eMode (efficiency mode), and cross‑chain liquidity routing via the Comet architecture. The upgrade expands the attack surface considerably compared with V2, especially around:
Overall, the protocol’s core accounting (interest accrual, liquidation, and reward distribution) remains solid and inherits the battle‑tested design of Compound V2. However, the new modular components introduce several high‑impact vectors that, if exploited, could lead to partial or total loss of collateral, reward theft, or a systemic liquidity freeze.
Overall Risk Score: 6.8 / 10 (Medium‑High).
The score reflects a mature codebase with a strong test suite, but the complexity of new features and incomplete formal verification of bridge adapters keep the residual risk elevated.
2. Identified Attack Vectors
#VectorAffected Component(s)DescriptionPotential ImpactLikelihood*1Isolated Market Parameter ManipulationIsolatedMarket.sol, RiskManager.solIsolated markets have independent collateral factors, liquidation thresholds, and supply caps that can be updated by governance. An attacker with a short‑term governance proposal (e.g., via a flash‑loan‑backed vote) could lower the collateral factor or raise the liquidation incentive, forcing premature liquidations.Forced liquidations → loss of user capital; market panic → TVL drain.Medium2Supply‑Cap Bypass via SupplyCapManagerSupplyCapManager.sol, Comet.solThe cap is enforced only on mint paths. Direct token transfers to the market’s underlying (e.g., via transferFrom on the underlying ERC‑20) can increase the market’s cash balance without updating the internal totalSupply, allowing the market to exceed its cap and create “phantom” liquidity that can be withdrawn later.Over‑minting → inflation of cTokens, dilution of existing holders.Low‑Medium3eMode Oracle ManipulationEModeOracle.sol, PriceOracleAggregator.soleMode uses a dedicated price feed (often a Chainlink aggregator with a reduced update frequency). An attacker who can front‑run or manipulate the underlying feed (e.g., via a flash loan on a low‑liquidity pair) can temporarily distort collateral valuations, enabling under‑collateralized borrowing.Under‑collateralized debt → liquidation loss, possible protocol insolvency in the eMode market.Medium4Cross‑Chain Bridge Re‑entrancyL2BridgeAdapter.sol, CrossChainRouter.solBridge adapters call external L2 contracts (e.g., Optimism’s L2StandardBridge) and then update internal accounting. If the external call triggers a callback that re‑enters the bridge’s deposit/withdraw functions before the state is updated, an attacker can double‑count assets.Double‑spend of deposited assets → loss of funds equal to the bridge’s liquidity.Low5Interest‑Rate Model Exploit (Jump Rate)InterestRateModel.solThe new jump‑rate model uses a piecewise function with a “kink” that can be manipulated by feeding a large amount of cash into the market (via a flash loan) to temporarily push utilization below the kink, causing the borrow rate to drop dramatically. Borrowers can then take large loans at near‑zero rates before the utilization spikes back.Massive cheap borrowing → increased liquidation risk, potential loss of reserves.Medium6Reward Distribution Race ConditionRewardDistributor.sol, Comet.solRewards are minted per‑block based on a snapshot of supply/borrow balances. If a user performs a rapid supply/withdraw cycle within the same block, they may receive rewards for a larger balance than actually held at the end of the block.Over‑rewarding → inflation of COMP/COMET token supply, economic loss.Low7Upgrade‑Proxy Mis‑configurationProxyAdmin.sol, TransparentUpgradeableProxy.solThe protocol uses the OpenZeppelin Transparent Proxy pattern. An admin key (held by the DAO multisig) could be compromised, allowing an attacker to point the proxy to a malicious implementation.Full control over all markets → total fund exfiltration.Low (but high impact)8Denial‑of‑Service via Gas‑Heavy LiquidationsLiquidation.sol, Comet.solLiquidation transactions can become gas‑intensive when many borrowers are under‑collateralized simultaneously (e.g., after a price shock). If the gas limit is insufficient, liquidations fail, leaving the protocol in an insolvent state until a privileged actor manually intervenes.Stuck liquidations → protocol insolvency, loss of confidence.Medium9Flash‑Loan Re‑entrancy on borrow/repayComet.solThe borrow function updates the borrower’s debt after transferring the underlying token. A malicious contract can re‑enter via a fallback that calls borrow again, inflating its debt without proper accounting.Over‑borrowing → under‑collateralized positions, potential loss of reserves.Low‑Medium10Immutable Library Dependency VulnerabilitiesMath.sol, SafeCast.solThe protocol imports several OpenZeppelin libraries via immutable bytecode. If a library upgrade is performed without a full redeployment, a previously patched vulnerability (e.g., in SafeCast overflow checks) could be re‑introduced.Arithmetic overflow → balance mis‑calculations, fund loss.Low
*Likelihood is assessed qualitatively based on current on‑chain data, known exploits in similar protocols, and the maturity of the code.

Hubo un tiempo en el que el mundo no se entendía… se temía.
No había ciencia que explicara lo que pasaba en el cielo o dentro del cuerpo, así que todo lo desconocido se llenaba de significado.
Y muchas veces, de terror.
Algunos de esos miedos hoy nos parecen sacados de una película, pero durante siglos fueron completamente reales.
Los cometas, por ejemplo, no eran un espectáculo bonito.
Eran señales.
En muchas culturas se veían como “espadas de fuego” o “estrellas peludas” que anunciaban guerras, la muerte de reyes o el fin de un imperio.
El miedo era tan fuerte que incluso en 1910, con el paso del cometa Halley, la gente compraba máscaras de gas y pastillas “anticometa” por si el aire se volvía venenoso.
El viento tampoco era solo viento.
En lugares como Mesopotamia se creía que entidades como Pazuzu viajaban en él, trayendo peste y desgracias.
Un golpe de aire en mitad de la noche no era clima… era algo pasando.
Y luego está uno de los más inquietantes: la parálisis del sueño.
Hoy sabemos lo que es, pero durante siglos la gente sentía una presencia encima del pecho, sin poder moverse ni gritar.
De ahí nacen figuras como los súcubos o los íncubos.
No era una pesadilla: era algo que te estaba visitando.
Otro miedo muy real era el entierro prematuro.
Sin tecnología médica, no siempre era fácil distinguir entre la muerte y ciertos estados como la catalepsia.
El terror a despertar bajo tierra llevó a inventar ataúdes con campanas o tubos de aire.
Si alguien “volvía”, podía avisar desde dentro.
En la Europa medieval existía también el miedo a los “changeling”: que un ser feérico o demoníaco reemplazara a un niño.
Si un bebé enfermaba o cambiaba de comportamiento, algunos creían que ya no era el mismo.
Era otra cosa ocupando su lugar.
En la antigüedad clásica, incluso el propio cuerpo daba miedo.
Los griegos y egipcios creían en el “útero errante”, una especie de órgano que se movía por dentro del cuerpo causando asfixia o enfermedad.
No era una dolencia… era algo vivo dentro de ti.
En pantanos y bosques aparecían luces extrañas, los llamados fuegos fatuos.
Hoy sabemos que son gases, pero antes se creía que eran espíritus que engañaban a los viajeros para llevarlos a la muerte.
Seguir una luz en la niebla podía ser lo último que hicieras.
Los eclipses eran otro momento de pánico colectivo.
En distintas culturas se pensaba que una criatura estaba devorando el sol: un dragón, un lobo, un jaguar…
La gente hacía ruido, gritaba o golpeaba objetos para “asustar” a la bestia y devolver la luz.
Los volcanes tampoco tenían explicación lógica.
Eran dioses enfadados, gigantes despertando o fuerzas que exigían sacrificios.
Cuando el cielo se cubría de ceniza y el día se volvía noche, no había duda: algo enorme estaba pasando bajo tierra.
La sombra, algo tan cotidiano, también tenía carga espiritual.
En muchas culturas se creía que era una extensión del alma.
Si alguien dañaba tu sombra, te dañaba a ti.
Perderla o no verla era sentirse incompleto, vulnerable.
El mal de ojo era otro miedo constante.
No era superstición ligera, sino una fuerza real para quien la creía.
Una mirada cargada de envidia podía enfermar, arruinar cosechas o incluso matar.
Por eso surgieron amuletos como la higa o la mano de Fátima.
Y mucho antes de los zombies modernos, ya existía el miedo a los muertos inquietos.
Los “revenants” eran cadáveres que regresaban si no habían sido enterrados correctamente o si murieron con odio.
En excavaciones se han encontrado cuerpos con piedras en la boca o estacas en el pecho para impedir su regreso.
Para protegerse de todo esto, no bastaba con rezar.
Había objetos específicos.
En Roma, los niños llevaban una bulla, un amuleto para proteger su alma.
En Egipto, el escarabajo se colocaba sobre el corazón del difunto para asegurar su paso al más allá.
La higa se usaba para bloquear el mal de ojo.
Y las campanas de ataúd eran una especie de “seguro” contra el peor de los errores.
Hay incluso relatos históricos que refuerzan estos miedos.
Como el del llamado “vampiro de Alnwick”, recogido por el cronista medieval Guillermo de Newburgh.
Un hombre que, tras morir, supuestamente regresaba por las noches trayendo peste.
Según la historia, tuvieron que desenterrarlo, atravesarlo y quemarlo para que todo terminara.
Los espejos también daban miedo.
No reflejaban, mostraban el alma. Romper uno no era mala suerte por superstición, sino porque se creía que fragmentaba tu esencia.
De ahí la idea de los siete años necesarios para que “se recompusiera”.
Incluso los gatos, hoy tan normales, llegaron a ser vistos como peligrosos.
Se decía que podían robar el aliento a los bebés mientras dormían.
En realidad, era una forma de explicar la muerte súbita, pero el miedo llevó a sacrificar muchos animales.
Y por último, algo tan simple como un nombre.
En muchas culturas, conocer el nombre verdadero de alguien era tener poder sobre él.
Por eso existían nombres públicos y nombres secretos.
Revelarlo era exponerse completamente.
Visto hoy, todo esto puede parecer exagerado.
Pero en su momento era la única forma de darle sentido a un mundo lleno de cosas que nadie podía explicar.
Y en el fondo, aunque cambien las formas, ese impulso sigue siendo el mismo: intentar entender lo desconocido… aunque dé miedo.
