  9. And here's an adorable leopard gecko.

    All lizards have rigid facial muscles, so the "smile" isn't actually an expression of emotion. That is not to say that lizards can't express being contented and feeling pleased, they just don't do it using their faces. Lizard body language is often pretty easy to read if you're familiar with them.

    Leopard geckos are a bit unusual among geckos, because they don't have the famous adhesive* toepads - but they *do* have movable eyelids. Such is the gecko character point allocation - either you get magic super-climbing, or you get eyelids.

    *) They're not actually "sticky". They are covered in billions of tiny recursive hair-like structures which exploit van der Waals forces to hold on using literally atomic-scale interactions. No gunk involved.

  10. Large Language Models (LLMs) are very good at understanding the intent of the user and can give exceptionally good and accurate responses at the start of a session. When you are starting out a fresh session, it does not matter whether you are talking about science, literature, mathematics, or planning to find extraterrestrial life in our galaxy — it will give you the response you are looking for.

    But as the session moves forward and the input window grows, the responses seem irrelevant or vague, and the results no longer align with your mental image.

    Most people will think there is some issue in their prompt or writing style, or that maybe they are not clarifying the idea properly, and they end up confusing the LLM even more as the session decays.

    But the issue is not in your idea or writing style. It is in the LLM itself. The information you are giving is not wrong, but the LLM starts to pay less attention with each passing input as the context window grows. This issue is known as Context Rot.

    What is Context Rot?


    Context Rot is a flaw in the architectural design of LLMs, and it has been there for the last 5–6 years. It is a phenomenon that degrades the performance of LLMs whenever they try to process a long context.

    The problem is that the information is present in the context, but the model is unable to identify it within the context window.

    Context Window is the working memory of an artificial intelligence or LLM — it is the maximum amount of data that an AI can see or remember during an active session.


    The explanation for this problem is quite simple. The architecture of AI is designed in such a way that it naturally focuses on the beginning and end of the input and neglects the middle part. This means adding more context or information actually reduces the accuracy of the system — the attention of the AI becomes vague, and it starts hallucinating. This is known as "Lost in the Middle."

    Researchers discovered Lost in the Middle using a famous technique called the "Needle in the Haystack" (NIAH) test, which was introduced by AI educator and YouTuber Greg Kamradt.

    Needle in the Haystack


    It is a test conducted on LLMs to evaluate the ability of a model to retrieve a specific, isolated piece of information from a large context.

    As AI companies expanded and started marketing their AI products with large context windows — such as 1M, 2M, and 10M tokens — researchers needed a benchmark test to validate the claims behind these windows. During the research, they started noticing the Context Rot flaw, and to prove it, they introduced this technique to show how an AI becomes irrelevant even when its context window spans millions of tokens.

    How the test works


    • The Haystack: A massive amount of content is loaded into the LLM's context window, such as an essay collection, documentation, or a research paper.
    • Needle: A random, out-of-context question is given to the LLM to describe or solve within the given content. This tests not only the model's matching ability but also its thinking capability.
    • Depth: The needle is inserted into the haystack at different depths, so the result is an average across many positions — some easy, some difficult.
    • Length: The haystack amount starts from 2,000 tokens and goes up to the outer bounds of the model's context window.
    • Results: The outcome of NIAH is obtained after a recursive process of testing and evaluating different combinations of depth and context length.


    Lost in the Middle


    Even though NIAH is now used as an industry-standard tool, and top AI companies use it to showcase their powerful models, they are still unable to solve the biggest problem in AI: "Lost in the Middle." Models are still not able to manage such large chunks of data.

    To understand how the Lost in the Middle problem arises, we need to understand the under-the-hood functioning of an LLM. (To learn about transformer architecture in detail, visit Great Learning.)

    Large Language Models use the transformer architecture, which processes information and calculates relationships across an entire block simultaneously — unlike a human, who reads a sentence left to right. The model focuses on and emphasizes the beginning and end of the input, as these parts tend to reveal the user's intent or purpose.

    This architecture is the reason models do exceptionally well on early, standalone NIAH tests but fail completely during real-world, complex reasoning conversations, where key details get buried among the instructions.

    As there is no solution to this problem yet, you can use these workarounds in the meantime to increase your productivity with AI.

    Techniques to Work Around Context Rot

    1. Start Fresh Session


    Instead of mentioning every aspect of your goal in one go, divide your idea or work into small, manageable tasks and use a new session each time to complete a single task. This way, the LLM will only try to complete your intent in the most accurate manner and will not get confused by multiple requests stacked on top of each other.

    2. Handoff Approach


    This is a context management technique where you summarize the LLM's output midway through the session and pass that summary down to a new session. It keeps the LLM's decision-making fresh.

    3. RAG (Retrieval-Augmented Generation)


    This is the most common technique used in enterprise settings to handle data at scale. In this technique, data is fetched from an external source or database in chunks using vectorization, and only the relevant chunk is fed into the LLM for that specific input. (If you need an in-depth explanation of RAG, visit GeeksForGeeks.)

    4. RLM (Recursive Language Models)


    This is one of the most recent approaches to context rot, described in the paper "Recursive Language Models" by Alex L. Zhang, Tim Kraska, and Omar Khattab at MIT.

    In this work, the researchers explain that context rot can be reduced by storing data as an out-of-context variable inside an isolated Python REPL (Read-Eval-Print Loop) environment. The root LLM never sees the full raw text and only receives small, constant-sized metadata about it; Python execution commands are then used to read, slice, and filter keywords to actively map out the massive variable. The printed output of its own code feeds back into its next logical step.

    If the model finds a dense, 10,000-word block of code or text that requires isolated semantic focus, it writes a line of code to call a fresh sub-instance of the LLM. This child model is born with a blank context window, and the root model aggregates the returned values from these sub-instances into the final response.

    FAQs


    Q: Is Context Rot the same thing as hallucination?

    Not exactly. Hallucination is when the model makes up information that was never there in the first place. Context Rot is different — the correct information is present in the context window, the model just fails to pay attention to it because it is buried in the middle of a long input. So Context Rot can end up causing hallucination, but the root cause is attention, not invention.

    Q: If I use a model with a bigger context window, will Context Rot go away?

    No, and this is the part most people get wrong. A bigger context window only increases how much data the model can technically hold, it does not fix how the model pays attention to that data.

    Q: How do I know if I am hitting Context Rot in my own conversations?

    The clearest sign is when the model starts giving vague, generic, or slightly-off responses after a long session, even though your prompt is clear and you have already given it all the information it needs.

    Q: Is there any permanent fix to Context Rot coming?

    Right now, no. It is still an open architectural limitation, which is why researchers are actively working on new approaches.

  11. Yield Strategy Optimization Report: Ethena USDe


    Target Protocol: Ethena USDe (TVL: $4634.5M)

    Yield Strategy Optimization Report – Ethena USDe

    Prepared by: [Your Firm] – Senior DeFi Security Research & Auditing Team

    Date: 22 Oct 2026

    1. Executive Summary


    Ethena USDe is a USD‑pegged stablecoin built on Ethereum and multiple L2 roll‑ups (Arbitrum, Optimism, zkSync). The protocol aggregates user deposits into a suite of yield‑generating strategies (e.g., lending on Aave, liquidity provision on Uniswap V3, structured products on GMX, and bespoke “fixed‑rate” vaults). As of the reporting date, USDe’s total value locked (TVL) is ≈ $4.63 B, making it one of the largest stablecoin ecosystems on L2.

    Our technical review focused on the yield‑strategy layer (Strategy Manager, Vault contracts, Strategy adapters, and the associated governance/oracle stack). The goal was to identify systemic weaknesses that could jeopardize capital efficiency, peg stability, or user funds, and to provide concrete, prioritized remediation steps.

    Key Findings

    CategoryFindingsSeverity*Oracle & PricingUSDe’s price feed relies on a composite of Chainlink, Uniswap V3 TWAP, and a proprietary “USDe‑Index” oracle. The Index lacks sufficient decentralisation on L2s and can be manipulated via low‑liquidity pools.HighStrategy ExecutionThe StrategyManager permits any approved strategy to call harvest() without a per‑strategy gas‑limit or re‑entrancy guard. A malicious strategy could trigger a recursive harvest, draining gas or forcing a forced‑exit of other strategies.Medium‑HighGovernance & Parameter UpdatesCritical parameters (e.g., maxUtilisation, strategyWhitelist, oracleWeight) are updatable via a 2‑day timelock but can be changed by a single‑key multi‑sig (3‑of‑3). Compromise of one key gives an attacker the ability to re‑weight the oracle or whitelist a malicious strategy.HighCross‑Chain BridgeUSDe’s L2‑to‑L1 bridge uses a custom “Optimistic Relay” that does not enforce a challenge period for L2‑originated withdrawals. This opens a vector for “withdrawal replay” attacks if the L2 state is compromised.MediumLiquidation & Debt ManagementThe DebtManager uses a single‑price oracle for collateral valuation. In stressed markets, rapid price swings can cause under‑collateralised positions to remain open, leading to systemic loss.MediumFlash‑Loan ExploitsSeveral strategies expose executeFlashLoan() without a whitelist of allowed callee contracts. An attacker could embed malicious logic that re‑enters the strategy’s accounting, inflating reported yields.MediumUpgradeabilityMost core contracts are proxy‑based with admin rights held by the same multi‑sig that controls governance. No “delay” is enforced on implementation upgrades, increasing the risk of a malicious upgrade if the multi‑sig is compromised.Medium‑Low


    *Severity is assessed on a High / Medium‑High / Medium / Low scale based on potential financial impact and exploitability.

    Overall, the protocol’s architecture is sound, but the oracle composition, governance key management, and certain strategy‑execution pathways present the most material risk to capital preservation and peg stability.

    2. Identified Attack Vectors

    #Attack VectorDescriptionPotential ImpactLikelihoodSeverity (1‑10)1Oracle Manipulation (USDe‑Index)The proprietary USDe‑Index aggregates price data from low‑liquidity L2 pools. An attacker can pump/dump these pools, skewing the composite price and causing the system to over‑mint or under‑redeem USDe.Peg deviation > 1 %, loss of collateral, forced liquidation of healthy vaults.Medium‑High (requires modest capital on L2).82Re‑entrancy in Harvest CallsStrategyManager.harvest() lacks a re‑entrancy guard. A malicious strategy can call back into harvest() of another whitelisted strategy, causing gas exhaustion or unintended state changes.Denial‑of‑service, loss of accrued yield, possible fund lock‑up.Low‑Medium (requires whitelisted malicious strategy).63Governance Key CompromiseThe 3‑of‑3 multi‑sig controls all critical parameters. If a single private key is compromised, an attacker can (a) whitelist a malicious strategy, (b) re‑weight the oracle, or (c) change maxUtilisation.Immediate capital outflow, peg break, systemic loss.Low‑Medium (targeted phishing or insider threat).94Bridge Replay / State‑ManipulationThe Optimistic Relay bridge does not enforce a challenge period for L2‑originated withdrawals. An attacker who gains temporary control of L2 state can replay a withdrawal request on L1, draining funds.Up to full TVL loss on the affected L2.Low (requires L2 consensus attack).75Flash‑Loan Re‑entrancy in StrategiesexecuteFlashLoan() is open to any callee. An attacker can flash‑loan assets, call a strategy’s internal accounting functions, and manipulate reported yields to trigger higher reward distribution.Inflation of rewards, dilution of existing holders, potential loss of underlying assets.Medium (flash‑loan bots are abundant).76Undercollateralised LiquidationsDebtManager uses a single‑price oracle for collateral valuation. Rapid price drops can leave positions under‑collateralised before liquidation triggers, causing a shortfall.Loss of collateral, reduced backing ratio, peg stress.Medium‑High (volatile market conditions).77Unrestricted UpgradeabilityProxy admin can upgrade core contracts without a timelock. If the admin key is compromised, a malicious implementation can be pushed instantly.Full protocol takeover, fund theft.Low‑Medium (depends on key security).88L2 Gas‑Price ManipulationCertain strategies rely on L2 gas‑price oracles for fee estimation. Manipulating gas‑price data can cause strategies to over‑pay or under‑pay, affecting profitability and potentially causing transaction failures.Reduced yield, user experience degradation.Low4


    Severity scores are on a 1‑10 scale (10 = catastrophic).

  12. Reading List – 2026-10-22

    Delegated authority, change validation, and current design constraints all become harder to take for granted as software does more work on its own. A purchase approval can bound what an agent may do; as code volume rises, the notes suggest CI capacity matters for validation, while stale design docs can misdirect later work. I’m left wondering how teams keep those checks effective when oversight is intermittent.

    While Amazon blocks AI agents, Walmart rolls out the welcome mat

    Walmart is treating agent purchases as a distinct authority to manage, not just another checkout path. Its Agent Profiles separate an agent’s transactions from the customer’s and let shoppers require approval per purchase or set a spending limit; Walmart also says agents can’t access payment details. What catches my attention is that these controls make delegation visible and bounded. For systems that let software act for users, that accountability has to survive a misbehaving agent, not just a successful purchase.

    After automation: Solo founding will be the default

    The article argues that automation shifts the solo-founder risk from cofounder conflict to loneliness: without someone close, a founder may lack pushback, someone to notice when they’re stuck, or encouragement through the last mile. It points to surrounding solo founders and other resources as the alternative, rather than adding a cofounder for convenience. What catches my attention is that faster building doesn’t supply those human checks. That suggests peer support is part of sustaining a solo company, not a substitute for a technical tool.

    Recursive launches Flint, a laptop coding model it says was largely built by AI

    Flint makes local coding assistance plausible by activating only 2.5 billion of its 40 billion parameters per task, alongside custom kernels and low-bit training that Recursive says cut its size by 71% with almost no quality loss. That puts offline use and private code within reach of a laptop, but the company says Flint needs more guidance than larger paid assistants, so large jobs may need decomposition. What catches my attention is the workflow tradeoff: keeping inference local may mean engineers do more task framing themselves.

    OpenAI CLI

    The CLI’s –debug flag logs HTTP request and response details, including bodies, so diagnostics can expose sensitive payloads. That makes debug output different from ordinary operational logs: capturing or forwarding it deserves the same care as handling the request itself. I’d treat enabling it as a deliberate choice, with a clear plan for where the logs go and who can access them.

    SBD: We Have a Filesystem at Home

    SBD’s useful simplification is putting block metadata in the same bucket as the blocks, then letting ext4 manage files on a block device. That removes a separate metadata database from the consistency chain; SBD checks reads and restarts the Sprite if it can’t trust the disk. Since I’m using Sprites more in my own development, that fail-stop behavior catches my attention: it should reduce silent corruption paths, but a storage-daemon failure means a restart, not continued service.

    Meta to create a new class of shares to fund AI push

    Issuing non-voting shares to fund AI, acquisitions, and employee compensation reads to me as a possible AI-bubble signal. Meta expects $135–145 billion in capital expenditures this year, and says the new shares will begin trading in 2027. That spending scale makes the financing worth watching, though the article doesn’t establish that a bubble is forming; the harder question is whether the expected returns can support it.

    ‘I’d consider replacing one of my children’: Taika Waititi on robot kids, his cheese-o-meter and Klara and the Sun

    One useful boundary in the conversation: Ishiguro says Klara and the Sun shouldn’t be treated as an AI ethics handbook; the story isn’t about that, and better sources exist. Fiction can sharpen technical questions without supplying a framework for decisions. I loved the novel and am very much looking forward to the film; it’ll be interesting to see how its adaptation handles a story Ishiguro says shouldn’t be read as guidance for AI development.

    Anthropic unveils Claude Duet, its answer to AI agents like Dots

    It’s been strange to see Anthropic absent from the agent market; Duet feels like a welcome arrival. It runs in its own virtual machine and browser, so tasks can continue while your computer is off, but sending messages, making payments, signing documents, and deleting things still require permission. That gate limits some consequential actions, but it can’t correct a misread thread, bad urgency judgment, or missed update between check-ins. For unattended workflows, the open question is whether review arrives early enough to matter.

    Blacksmith hits unicorn valuation after Sequoia leads Series C

    AI-generated code makes CI capacity part of the trust boundary: Blacksmith’s CEO says companies are struggling to keep up with the builds and checks needed to validate changes. I moved my jobs from GitHub to Blacksmith a few weeks ago and am really happy with the move; Blacksmith reports running 90 million CI jobs, though the article doesn’t say how it performs. For teams, the question is whether more capacity can keep validation thorough as change volume rises.

    Astronomers Pointed Webb at an Empty Spot in Space. Something ‘Highly Unusual’ Flashed Back

    One emission line can’t establish whether this came from a distant early galaxy or a nearer source. Cosmic expansion can shift high-energy light into infrared; a closer object can emit at lower energy. An early galaxy should have appeared in earlier images, while an active nucleus should have produced other lines. I find the gap between repeat detection and identified cause useful in debugging: one observable rarely settles a diagnosis.

    #Agents #AI #Developer #Infrastructure
  13. When transitioning from the manual, error-prone world of "ClickOps" in cloud portals to production-grade engineering, mastering Infrastructure as Code (IaC) is non-negotiable.

    In this walkthrough, we will explore a real-world project that provisions foundational Azure cloud networking using Terraform and the latest AzureRM 4.x provider, all orchestrated within an isolated DevPod containerized development environment powered by mise.

    Whether you're studying for cloud certifications or standardizing your team's cloud infrastructure footprint, this guide breaks down the architecture, codebase, security hygiene, and lessons learned along the way.

    🎯 Project Objectives


    Before writing a single block of HCL (HashiCorp Configuration Language), we outlined clear requirements:

    1. Deterministic & Repeatable Provisioning: Zero reliance on manual Azure Portal configurations.
    2. Predictable Developer Workspace: Avoid version discrepancies across developer machines by leveraging DevPod, Docker, and mise.
    3. Sound Networking Foundations: Establish an isolated Virtual Network (VNet), dedicated application subnet, and Network Security Group (NSG).
    4. Strict Security Hygiene: Isolate credentials using Microsoft Entra ID service principals with zero secrets leaking into version control.


    🏗️ Architecture Overview


    The infrastructure deployed by this project represents the foundational landing zone for any cloud-hosted application:

    🧰 The Modern Developer Toolchain


    One common headache in cloud engineering is tool mismatch: "It works on my machine because I'm on Terraform 1.5, but CI failed because it's running 1.9."

    To eliminate this friction, this project couples DevPod / Dev Containers with mise:

    1. Unified Tooling with mise


    Instead of cluttering the host machine with multiple version managers (tfenv, nvm, pyenv), mise.toml pins exact binaries:


    [tools]terraform = "1.16.6"
    uv = "0.13.1"

    2. Isolated Workspace via Dev Containers


    Our .devcontainer/Dockerfile layers mise directly on an official Ubuntu 24.04 base:

    FROM mcr.microsoft.com/devcontainers/base:ubuntu-24.04

    COPY --from=jdxcode/mise /usr/local/bin/mise /usr/local/bin/

    🔐 Authentication & Credential Hygiene


    For automated Terraform deployments against Azure, authenticating as a Microsoft Entra ID Service Principal is the industry standard.

    Exporting AzureRM Credentials


    We configure authentication using the four core environment variables consumed natively by the HashiCorp AzureRM provider:

    • ARM_CLIENT_ID
    • ARM_CLIENT_SECRET
    • ARM_TENANT_ID
    • ARM_SUBSCRIPTION_ID

    These are stored locally in .env.azure (which is strictly added to .gitignore):

    export ARM_CLIENT_ID="<YOUR_APP_REGISTRATION_CLIENT_ID>"
    export ARM_CLIENT_SECRET="<YOUR_CLIENT_SECRET_VALUE>"
    export ARM_TENANT_ID="<YOUR_ENTRA_TENANT_ID>"
    export ARM_SUBSCRIPTION_ID="<YOUR_SUBSCRIPTION_ID>"

    To load them cleanly in your active shell:

    set -a
    source .env.azure
    set +a


    ⚠️ Security Tip: Always verify that your credentials file is ignored by Git prior to making commits:
    git check-ignore -v .env.azure


    💻 Terraform Code Structure


    A clean, modular folder layout ensures that code remains readable and easy to maintain as infrastructure grows:

    azure-terraform/
    ├── .devcontainer/
    │ ├── devcontainer.json
    │ └── Dockerfile
    ├── .gitignore
    ├── .env.azure # Keep local & secret!
    ├── mise.toml
    ├── README.md
    └── terraform/
    ├── versions.tf # Terraform & provider constraints
    ├── providers.tf # Provider configurations
    ├── variables.tf # Configurable input parameters
    ├── main.tf # Resource definitions
    └── outputs.tf # Exported attributes

    Let's inspect the key configuration files:

    1. terraform/versions.tf & providers.tf


    Pinning modern versions avoids surprise breaking changes:

    # versions.tf
    terraform {
    required_version = ">= 1.6.0"

    required_providers {
    azurerm = {
    source = "hashicorp/azurerm"
    version = "~> 4.0"
    }
    }
    }

    # providers.tf
    provider "azurerm" {
    features {}
    }

    Note: In azurerm v4.0+, the features {} block remains mandatory.

    2. terraform/variables.tf


    Parameterizing region, names, and CIDR blocks keeps our configuration DRY:

    variable "resource_group_name" {
    description = "Name of the Azure resource group"
    type = string
    default = "rg-terraform-lab"
    }

    variable "location" {
    description = "Azure region for the infrastructure"
    type = string
    default = "Central India"
    }

    variable "vnet_address_space" {
    description = "Address space for the virtual network"
    type = list(string)
    default = ["10.10.0.0/16"]
    }

    variable "subnet_address_prefixes" {
    description = "Address range for the application subnet"
    type = list(string)
    default = ["10.10.1.0/24"]
    }

    3. terraform/main.tf


    Here we provision the resource group, virtual network, subnet, NSG, and their association:

    resource "azurerm_resource_group" "lab" {
    name = var.resource_group_name
    location = var.location

    tags = {
    environment = "lab"
    managed_by = "terraform"
    project = "azure-infrastructure"
    }
    }

    resource "azurerm_virtual_network" "lab" {
    name = "vnet-terraform-lab"
    location = azurerm_resource_group.lab.location
    resource_group_name = azurerm_resource_group.lab.name
    address_space = var.vnet_address_space

    tags = {
    environment = "lab"
    managed_by = "terraform"
    }
    }

    resource "azurerm_subnet" "app" {
    name = "snet-app"
    resource_group_name = azurerm_resource_group.lab.name
    virtual_network_name = azurerm_virtual_network.lab.name
    address_prefixes = var.subnet_address_prefixes
    }

    resource "azurerm_network_security_group" "lab" {
    name = "nsg-terraform-lab"
    location = azurerm_resource_group.lab.location
    resource_group_name = azurerm_resource_group.lab.name

    tags = {
    environment = "lab"
    managed_by = "terraform"
    }
    }

    # Explicit decoupling: association resource rather than an inline subnet block
    resource "azurerm_subnet_network_security_group_association" "app" {
    subnet_id = azurerm_subnet.app.id
    network_security_group_id = azurerm_network_security_group.lab.id
    }


    💡 Best Practice Note: Avoid declaring subnets inline within the azurerm_virtual_network resource. Managing azurerm_subnet and azurerm_subnet_network_security_group_association as dedicated resources avoids configuration drift, circular dependencies, and unexpected resource replacements.


    4. terraform/outputs.tf


    Outputs expose resource attributes that downstream modules or CLI scripts can consume:

    output "resource_group_name" {
    description = "Azure resource group name"
    value = azurerm_resource_group.lab.name
    }

    output "virtual_network_name" {
    description = "Azure virtual network name"
    value = azurerm_virtual_network.lab.name
    }

    output "virtual_network_id" {
    description = "Azure virtual network resource ID"
    value = azurerm_virtual_network.lab.id
    }

    output "subnet_id" {
    description = "Application subnet resource ID"
    value = azurerm_subnet.app.id
    }

    output "network_security_group_id" {
    description = "Network security group resource ID"
    value = azurerm_network_security_group.lab.id
    }

    🚀 Execution & Verification Flow


    Navigating to the terraform/ directory, the deployment follows the canonical Terraform workflow:

    1. Initialization & Linting


    # Initialize working directory & download AzureRM provider
    terraform init

    # Canonical format checking
    terraform fmt -recursive

    # Syntax and structural validation
    terraform validate

    2. Planning


    terraform plan

    Terraform determines the execution graph and confirms the exact 5 resources to be created:

    Plan: 5 to add, 0 to change, 0 to destroy.

    3. Application


    terraform apply

    Type yes when prompted. In less than 30 seconds, Azure confirms all resources are created.

    4. Verification


    Inspect the live state directly from your terminal:

    terraform state list

    Expected output:

    azurerm_network_security_group.lab
    azurerm_resource_group.lab
    azurerm_subnet.app
    azurerm_subnet_network_security_group_association.app
    azurerm_virtual_network.lab

    You can view the exported IDs at any time:

    terraform output

    Or verify them using the Azure CLI:

    az network vnet show \
    --resource-group rg-terraform-lab \
    --name vnet-terraform-lab \
    --output table

    🛡️ Critical Lessons Learned & Production Considerations

    1. Local State vs. Remote Backend


    In this learning lab, local state (terraform.tfstate) is used. However, in a team or production setup, never rely on local state. Local state cannot prevent concurrent writes and risks leaking secrets.
    Production path: Migrate to an Azure Blob Storage backend with state locking via Azure Blob Leases:

    terraform {
    backend "azurerm" {
    resource_group_name = "rg-tfstate"
    storage_account_name = "sttfstatelab123"
    container_name = "tfstate"
    key = "networking.terraform.tfstate"
    }
    }

    2. Avoid Static Client Secrets in CI/CD


    While .env.azure is great for fast local iteration, CI/CD pipelines (like GitHub Actions or GitLab CI) should utilize Azure Workload Identity Federation (OIDC). OIDC uses short-lived tokens without storing long-lived passwords or client secrets in your repository settings.

    3. Tagging Strategy


    Tagging resources early (environment = "lab", managed_by = "terraform") makes cost attribution and lifecycle tracking drastically easier as the infrastructure expands.

    🧹 Tearing Down (Zero Cost Surprise)


    When your lab session concludes, cleanup is just as important as creation to prevent runaway cloud charges:

    # Review what will be destroyed
    terraform plan -destroy

    # Tear down all resources cleanly
    terraform destroy -auto-approve

    🗺️ What's Next?


    From here, this foundation is primed for expansion:

    • [ ] Add Compute: Provision an Azure Virtual Machine or Azure Kubernetes Service (AKS) inside snet-app.
    • [ ] Implement GitHub Actions with OIDC for automated pull-request validation (fmt, validate, tflint, and plan).
    • [ ] Modularize the networking configuration into a reusable Terraform Module.

  14. Love the "accidentally reply not as a reply" trap of the mastodon UI

  15. I really think that when I get a tech job again it should be a tech job that involves cuddling cute animals and stuff like that

  16. When I show ApkPy to someone, the first question is almost always the same: how does this run Python on Android?

    It doesn't. ApkPy reads writehere.py and writes Java and XML. The APK from apkpy run has activities, layouts, drawables and a manifest, the same as an app built by hand in Android Studio. There is no Python interpreter inside, no WebView, and no CPython compiled as a library.

    I chose translation over embedding because of size. In the benchmark I published, the same 100-note app was 5.37 MiB in debug and 1.48 MiB in the signed release. With an interpreter inside, the starting point would be different. And because the generated code is plain Java, the camera and background audio are Android APIs, not bridges to them.

    The cost shows up when I write Python ApkPy cannot translate yet. The build stops on that line and says what to write instead.

    1.14.0, out on October 20, was mostly about that. Most of the Python people write every day now goes through: a, b = parts, for key, value in d.items(), items.pop(), sorted(), comprehensions inside functions, f-string widths ({n:05d}), *args, functions inside functions, recursion, try/except and for ... else.

    Some of it was less visible than new syntax. The generated Java is now checked against CPython on the same inputs, accents and emoji included.

    1.14.0 also tightened installation. apkpy setup now checks the sha256 of everything it downloads.

    The Python that translates is listed on Compatibility and limits.

    If you want to try it:

    python -m pip install --upgrade apkpy
    apkpy start hello
    cd hello
    python writehere.py

    writehere.py opens the Previewer. apkpy run generates the Android project and builds a debug APK next to it.#python #android #opensource #showdev #software #coding #development #engineering #inclusive #community
    Why there is no Python inside an ApkPy APK

  17. 🧿𝑫𝒐𝒓𝒐𝒕𝒉𝒚 𝑪𝒓𝒐𝒘𝒇𝒐𝒐𝒕 𝑯𝒐𝒅𝒈𝒌𝒊𝒏 🧿

    Dorothy Crowfoot Hodgkin tenía las manos deformadas por la artritis reumatoide.
    Los dedos se le fueron torciendo con los años, caminar se convirtió en una dificultad y acabó necesitando una silla de ruedas.
    Hasta las tareas más sencillas podían resultarle dolorosas, pero siguió trabajando en aquello a lo que había dedicado buena parte de su vida: averiguar cómo estaban construidas algunas de las moléculas más importantes para los seres vivos.

    Había nacido en El Cairo el 12 de mayo de 1910, donde su padre, John Winter Crowfoot, trabajaba como arqueólogo.
    Su madre, Grace Mary Hood, era una mujer culta, interesada en la botánica y en las ciencias naturales.
    Dorothy pasó su infancia entre libros, plantas, fósiles y conversaciones sobre el mundo que la rodeaba.
    A los diez años ya sentía una enorme curiosidad por los cristales y sus formas geométricas.
    Le fascinaba que una sustancia pudiera organizarse siguiendo una estructura tan precisa, aunque todavía no podía imaginar hasta dónde la llevaría aquel interés.

    En 1928 entró en Somerville College, en Oxford, para estudiar Química.
    Allí descubrió la cristalografía de rayos X, una técnica que permitía investigar la estructura de la materia sin necesidad de ver directamente sus átomos.
    Se hacía pasar un haz de rayos X a través de un cristal y se estudiaba el patrón que aparecía al otro lado.
    Interpretando aquellas señales mediante cálculos matemáticos, era posible reconstruir la disposición de los átomos que componían una molécula.
    Lo que para otros podían ser manchas difíciles de interpretar, para Dorothy era una manera de averiguar cómo estaba organizado un mundo invisible.

    A los 24 años le diagnosticaron artritis reumatoide, una enfermedad inflamatoria que fue dañándole las articulaciones de las manos y los pies.
    Los tratamientos disponibles entonces eran muy limitados y su movilidad empeoró con el paso del tiempo.
    Tuvo que adaptar su forma de trabajar y apoyarse en sus colaboradores para determinadas tareas, pero no abandonó la investigación.
    Su trabajo requería paciencia, cálculos complejos y años de observaciones; precisamente por eso, cada avance suponía resolver una dificultad científica considerable.

    Uno de sus primeros grandes retos fue la penicilina.
    Durante la Segunda Guerra Mundial, este antibiótico se había convertido en una herramienta fundamental para combatir infecciones, pero todavía era necesario conocer con precisión su estructura química.
    Dorothy y su equipo recurrieron a la cristalografía de rayos X para estudiarla y en 1945 lograron determinar su estructura.
    El resultado ayudó a confirmar la presencia del anillo beta-lactámico, una parte esencial de la molécula y una pieza clave para comprender cómo estaban construidos estos antibióticos.

    Después se enfrentó a la vitamina B12, una molécula mucho más compleja de lo que podían abordar fácilmente las técnicas de la época.
    El trabajo exigió años de investigación y cálculos, hasta que en 1955 su equipo consiguió determinar su estructura.
    Aquello supuso un avance extraordinario para la química estructural y consolidó la reputación de Dorothy Hodgkin como una de las investigadoras más destacadas de su campo.

    Pero había otro problema al que llevaba dedicando tiempo desde 1934: la insulina.
    Se trataba de una proteína cuya estructura tridimensional era especialmente difícil de descifrar con los medios disponibles.
    Dorothy continuó trabajando en ella durante décadas, mientras su artritis avanzaba y las limitaciones físicas se hacían cada vez más evidentes.
    Finalmente, en 1969, su equipo consiguió determinar la estructura de la insulina.
    Habían transcurrido unos 35 años desde que comenzó a estudiarla, una muestra de lo complicado que resultaba aquel trabajo antes de disponer de las herramientas informáticas y experimentales actuales.

    Cinco años después de que comenzara aquella investigación, en 1964, Dorothy había recibido el Premio Nobel de Química por sus determinaciones mediante cristalografía de rayos X de las estructuras de importantes sustancias bioquímicas.
    Tenía 54 años y se convertía en una de las científicas más reconocidas del mundo.
    Sin embargo, algunos periódicos británicos presentaron la noticia haciendo hincapié en que era una «ama de casa».
    Resulta llamativo que, ante una investigadora que había realizado descubrimientos fundamentales para la química, parte de la prensa destacara su condición de mujer casada antes que su trayectoria científica.

    Su vida tampoco se limitó al laboratorio.
    Dorothy defendió la cooperación internacional entre científicos y participó en el movimiento Pugwash, dedicado a promover el diálogo sobre los peligros de las armas nucleares.
    Consideraba que quienes trabajaban en ciencia también tenían una responsabilidad con la sociedad y debían pensar en las consecuencias de sus descubrimientos.
    Además, se preocupó por las dificultades a las que se enfrentaban las mujeres que querían desarrollar una carrera científica sin renunciar a su vida familiar.
    Ella misma había tenido tres hijos y conocía bien los problemas de conciliar ambas cosas.
    En Somerville College apoyó la creación de una guardería y destinó parte del dinero de su Nobel a contribuir a su financiación.

    Entre las personas que pasaron por sus clases estuvo Margaret Thatcher, que estudió Química en Oxford antes de convertirse en primera ministra británica.
    Sus ideas políticas eran muy diferentes, pero mantuvieron el contacto a lo largo de los años.
    La relación entre ambas es una de esas curiosidades que acompañan a la biografía de Dorothy, aunque su legado científico fue, con diferencia, mucho más importante que cualquier vínculo personal.

    Se jubiló oficialmente de Oxford en 1977, pero siguió vinculada a la investigación y a la comunidad científica.
    Murió el 29 de julio de 1994, a los 84 años, después de una vida dedicada a estudiar estructuras que no podían observarse directamente.
    Su trabajo ayudó a demostrar hasta dónde podía llegar la cristalografía de rayos X y abrió nuevas posibilidades para comprender moléculas esenciales para la vida.

    Quizá su nombre no resulte tan familiar para el público como el de Marie Curie, pero sus investigaciones dejaron una huella profunda en la química y la biología.
    Conocer la estructura de la penicilina, la vitamina B12 o la insulina no era un simple ejercicio teórico: permitía comprender mejor cómo funcionaban estas sustancias y proporcionaba información fundamental para futuras investigaciones.

    La artritis nunca desapareció y Dorothy no tuvo un final milagroso en el que la enfermedad dejara de limitarla.
    Aprendió a trabajar con las dificultades que tenía, recurrió a la colaboración de otras personas y siguió investigando durante décadas.
    Su historia no necesita adornos: una niña fascinada por los cristales acabó convirtiéndose en una de las científicas que más contribuyeron a revelar la arquitectura invisible de la vida.

  18. Stop Cheating!

    I use an LLM for a critic. That’s fine.
    However, when I ask it a question about my work, it wants to do more than just answering. It offers:

    • suggestions on how to organize my work
    • language it thinks is better than mine, and
    • topics or next steps it “thinks” I want to do next.

    All of These are Cheating

    I’m working on books and essays, and checking the argument structure, dramatic arc, and line-by-line logic. If I want a synonym for herpetology, I’ll darn well ask.

    Anything I publish has to meet normal standards of professionalism, like no plagiarism. Exactly as when writing an essay in university, I need to follow the classic set of “academic integrity” rules.

    That means I needed to invent prompts to shut the “helpfulness” up.

    Recursion

    To get a good, reusable prompt, first ask the LLM what it would say. I asked it about checking sentence logic for a project of mine. Consider it a prompt for “marking the homework I just handed in (:-))”

    It replied: Here’s a ready-to-use prompt template. Paste your draft after it, and it will force sentence-level critique with inline diagnostics.

    Act as a rigorous academic editor and domain expert. Process the following passage sentence by sentence. For each sentence, there will be one of more lines of premises or conclusions

    Produce exactly four things, followed by a blank line:
    [Quote the sentence from the passage]
    [Quote each of the premises or conclusions I wrote about the sentence]
    Assessment: [1–2 sentences on clarity, accuracy, rhetorical function, and alignment with the sentence]
    Diagnosis: [Concrete revision, textual/philosophical correction, or structural note. If it works, explain why. If it drifts, specify where to fix it, but not how.]
    After processing all sentences, provide a 3–4 sentence summary of the passage’s overall strengths, weaknesses, and the single highest-leverage revision to strengthen the core argument.

    After a few experiments with a very simple example passage, I removed all the places where it wanted to make suggestions, and got the prompt above.

    That got it to stop trying to sell me on using its (boring!) style.

    Sucking up

    You’ll remember my first fix for sucking up:

    Give me straightforward responses without praise.

    That worked some of the time, but whenever I asked it to show me the good things in an input, it started kissing up. So I added overrides to that part of my instructions in several of my prompts . This is an example:

    You are not rewriting the author's work. You are not imposing your own preferences about style, voice, or subject matter. You are not copyediting — flag persistent language issues if they affect clarity, but do not line-edit. And you are not expected to solve every problem you identify; identifying the problem clearly is enough.
    Start with what the part does well, because the author needs to know what to preserve. Be careful not to praise: being mentioned in this section is enough. Praise will make you sound insincere, and therefore less trustworthy, defeating the whole purpose of this review.

    In my opinion, the most important thing is to have the LLM generate a prompt, then test it on some representative data, and nit-pick until it does what you want. Then try it on a different example. And tell it to stop sucking up like Augustine’s Evodius.
