  1. Saying “never bet against Elon” does not actually make you look smart

    The world’s richest man has been more of a main character in the news cycle than usual over the past 10 days, which is saying a lot. We had Elon Musk’s showoff of a “flying car” version of the future Tesla Roadster (“jumping car” more accurately describes this exercise in cold-gas vaporware), more announcements of steps to turn Starlink Mobile into a full-fledged network (never mind SpaceX’s severe shortfall of terrestrial spectrum) and Musk hyping a Tesla-SpaceX merger (SpaceX shareholders might want to hold their applause).

    Whatever Musk says, you can expect one reaction from many people who should know better: Never bet against Elon.

    That saying seems to come from Musk’s former business partner Peter Thiel, but it’s become a bit of a mantra–especially on X, where Musk has drawn a weird Greek chorus of sycophantic superfans who either don’t mind or outright cheer his racist rants about immigrants.

    I understand how that phrase can be easy to invoke from the legit accomplishments of SpaceX and Tesla. I’ve experienced them firsthand–watching one Falcon 9 and two Falcon Heavy launches at Cape Canaveral, then doing a nearly-1,700-mile road trip in a Model 3 in 2022–and I’ve written my share of appreciative things about both companies, SpaceX especially.

    But as a catchall rationalization of everything Elon says he’ll make happen, “never bet against Elon” amounts to weak-minded foolishness. Of course you can bet against the guy–and in three obvious cases, your wager could have paid off well.

    Cybertruck: Tesla’s metal trapezoid of a truck may seem ubiquitous because of how easy it is to spot one of these things from a quarter-mile away, but in reality it’s sold worse than Ford’s Edsel.

    Tesla’s slumping sales could use a boost right now. But instead of shipping a lower-cost EV that might help Tesla compete with the affordable electric cars from BYD and other Chinese automakers that are now racking up sales outside the U.S., the company introduced this $74,990-and-up monstrosity that isn’t street-legal in Europe.

    I imagine that the reaction to that poor choice–and to the not-really-flying Roadster and to the still-vaporware Optimus robot that for some reason graces Tesla’s Georgetown showroom in D.C.–among China’s EV industry remains whatever “LOL” is in Mandarin.

    Hyperloop: Musk’s notion of vehicles whooshing through low-pressure tubes at hundreds of miles an hour deserved skepticism when he revealed it in 2013 as a supposedly superior alternative to building high-speed rail in California (not that there isn’t much to critique about CAHSR’s management and design failures).

    Musk not committing his own money and his own Boring Company operation to build hyperloop networks should have been a tell. Instead, startups lined up investors to build versions of this design in places like Abu Dhabi, then failed to pour concrete because the design proved unworkable.

    Much closer to Washington, former Maryland governor Larry Hogan (R.) fell for this nonsense in 2017 and then watched the concept of a D.C.-NYC hyperloop unravel over the next few years. Elsewhere around the world–notably China–high-speed rail has kept rolling.

    Political donations: Yes, Musk spending more than a quarter of a billion dollars to help Donald Trump get elected in 2024 may have helped in swing states. But what happened months later when Musk spent another $20 million in just one of those states, Wisconsin?

    Dropping that much money there–plus briefly touting an illegal $1 million sweepstakes for voters–did not swing an April 2025 election for a spot on the state Supreme Court. Despite Musk declaring that “Western civilization” was somehow at stake should Brad Schimel (R.) lose, the people of Wisconsin voted for the judge’s Democratic opponent, Susan Crawford, by an almost 10-point margin.

    One possibly relevant factor: Musk’s approval ratings in polls are now almost as bad as Trump’s, and Musk can’t claim anything like Trump’s cult of personality.

    The appropriate response to any version of “never bet against Elon” is “citation needed.” Musk has done some extraordinary things but now seems extraordinarily detached from the societal circumstances that result in most people proffering dumb ideas having their peers tell them “that’s a dumb idea.”

    Too many media-industry folks, meanwhile, need to stop bringing a “never bet against Elon” mindset to covering Musk’s predictions or pledges in what my fellow tech scribe Karl Bode mocks as “CEO Said a Thing” stories. Journalists do their readers a disservice when they fail to remind them of Musk’s spotty record of delivering on his promises–and freelance journalists do their own incomes a disservice by passing on such an easy way to pad out their word counts.

  2. In addition, there is an app if you need to print from your phone... And the printer is 100% wifi compatible.
    The ONLY complaint I have is that it doesn't come with a dedicated printer cable. And I have learned over the last decade that printer Wi-Fi has 4 prospective problems.
    1. If wifi isn't strong enough, connections are iffy. And many printers are truly only designed for Wi-Fi. The fact that they no longer include a printer cable is their way of pushing you to Wi-Fi printing.
    2. Wi-Fi traffic seems to heavily affect Wi-Fi signal strength, which makes #1 significantly more problematic.
    3. Ink subscriptions (especially after cancellation) will negatively influence ease of use. The manufacturer swears that subscriptions are not mandatory, but they do everything in their power to make the non-subsciption experience so unpleasant that most people will just keep the subscription to avoid the hoop-jumping requirements, to exit the subscription.
    But I happened to have the 10ft one I bought for the prior printer, because, after living in a lot of places where the WiFi is iffy, I prefer old school.
    4. Wi-Fi is hackable, most printer Wi-Fi is unsecured, and all printers keep a log. If I wanted the world to know what I am printing, I would post it on FB.

    Last Day of the Full Moon

    Neptune, Saturn, Chiron, Uranus, Venus, Mercury Retrograde

    Sunny and cool

    Yessiree Bob, Mercury is Retrograde again. Try to avoid signing contracts or buying anything big. Find cool stuff in thrift shops. Think A LOT MORE before you say a word – even more important when Mercury and Venus are retrograde at the same time.

    Friday was sunny and cold. I was out of the house on time and at CVS for my COVID shot. No worries, no hassle this time. Getting home was a little fraught – more delays than usual, things slower, etc., and I started feeling the effects of the shot faster.

    I usually feel it within 20 minutes, then it steadies out for 6-8 hours, then I’m miserable for however many days I’m down.

    This time, I started feeling it in 10 minutes. I made it home, but my arm was quite sore within the first half hour. I’d drunk the 16 oz. of water the hour before the shot, as instructed. I continued to be thirsty, and by noon (my shot was at 9), I had consumed a gallon of water, and wanted more. So that was new and different. But I went with it. I’m not much of/enough of a water drinker, but I craved it and trusted it.

    I started feeling weary early on, and my nerve endings were on fire. I imagine this is what a fibromyalgia flare feels like. My joints also ached, and creaked loudly every time I moved, to the point it woke up the cats. New and different. I’ve always had muscle aches (which I also had), but not the nerve/joint stuff to this extent. I had some sense of brittle joints last go-round, but it was different than this, and moved through in about 5-6 hours. All of this will go in a document to the John Hopkins study in which I’ve participated in for the last handful of years. That’s why I paid such close attention.

    I took care of some business that needed attention while I was still coherent, drank as much water as I wanted, and took up residence on the sofa in the sunshine with the cats.

    I’m usually ravenously hungry on the first day of the shot, but was not. I was mildly nauseated for a couple of hours, but it passed.

    I wrote while I still could, and had books still close at hand for when I started to wind down. The headache came in faster, too, this time around, within three hours instead of the usual 6.

    I hoped that symptoms coming in hard and fast meant they’d flow through faster, too. But that’s why I blocked out several days. So that the only thing I needed to do was heal.

    I was actually functional enough to cook dinner using some CSA ingredients. I went to bed early, so tired I could barely drag myself there.

    I woke up a little after midnight on Saturday with severe chills. I added the featherbed to the blanket cover, which helped. Charlotte even allowed Tessa to come on the bed and help warm me.

    Then the muscle aches began. Everything hurt as badly as the first vaccine with Moderna way back in the day. I couldn’t take Tylenol because it made me so nauseated. I finally fell asleep, waking up a few hours later with a fever. Got back to sleep, woke up with chills.

    At one point, I could swear Charlotte and Willa were swinging from the ceiling fan in my office, but I could have had audio hallucinations.

    I moved to the sofa around 6 and slept there all day. I woke up every 3 or 4 hours for about 15 minutes or so, and went right back to sleep. I did manage a few sentences of free-writing, so I didn’t miss a day. I couldn’t even tie my hair back, because it hurt too much.

    I tried to eat, but everything tasted like wet cardboard, and nauseated me even more. I couldn’t eat more than 2 or 3 bites of anything. I drank as much liquid as possible, although I could only stand a few sips of coffee.

    You know it’s bad when I don’t drink coffee.

    At least when I was asleep, I wasn’t aware of how bad I felt.

    I was back in my own bed by 6 PM.

    I woke up around 1:30 on Sunday morning, feeling a little better. I managed to get back to sleep, and even had a little bit of dreaming, a good sign.

    I got up at the usual time and slowly fed the cats. I wasn’t up to yoga or much meditation, but I did a bit of free-write.

    I managed to eat a little breakfast. By mid-morning, I could do the Community Tarot Reading for the Week, which you can read here.

    I spent most of the day on the couch, reading. I read a book by one of my favorite authors that was a disappointment. It focused on the pain without the whimsy or joy that her previous novels have. While I respect her trying something new, and it technically had a happy ending, I missed the small moments of beauty that I love so much in her work. I read a book by a different author whose work I’ve read for years. Some of her work I’ve loved, some didn’t do it for me. This, sadly, was the latter, and it was in present tense. I realize she’s changed her style for market reasons, but she’s also lost the complexity that drew me to her work in the first place.

    So not a satisfying reading day!

    I heated up some leftovers for dinner, and could actually taste the food again, which was an improvement.

    I was in bed again by 6:30.

    I woke up around 1:30 on Monday, feeling a little better, and plotted out a good bit of the next ghostwriting assignment.

    Fell asleep again, and dreamed I was at a conference center. There was a poetry convention in one section and a mystery convention in the other, and I kept running back and forth between them. Not the most restful of dreams, but an improvement over the weekend.

    Woke up again at the usual time, and fed the cats, and that just about did me in. I did a few yoga poses on the floor, with Tessa snuggled beside me, and then the 40-minute meditation and the 15-minute free-write.

    I played with some of my out-of-the-box ideas to protect my sites, as well as collecting some practical tools.

    There’s also this: Theft is a crime. A company putting it in its “terms of service” doesn’t make it less of a crime. So I’m filing with my state AG, and also contacting my state and federal reps about it.

    WP won’t allow me to install an AI blocker on this blog without paying a subscription fee, so I’ll be using one of the out-of-the-box solutions for the blog. I specifically don’t want this to be part of one of my websites, although I considered making a subdomain and exporting everything.

    Again, during a Mercury Retrograde? Big mistake.

    I am looking at some alternative social media platforms. Both Upscrolled and Monnett look good. Those would be sites where I wouldn’t have to keep posting about new releases cyclically for promotion. I could post once and be done. Cara, Joust, Curate, and PeakD don’t seem to be the right fit right now. I might try Curate at some point, when I have more visual work. Haven sounds promising, but isn’t even in Beta yet. Eh!, the Canadian social network, sounds like fun, but they might not want Americans at this point. I really miss Ello.

    I think when curation is too narrow, you miss a lot of cool stuff.

    I will spend more time on Bluesky, Mastodon, and Tumblr, too. I have accounts, I use all three in different ways, but I need to use them better.

    For now, I’ve switched my accounts on Meta to personal, rather than business. I removed my lkn.bio. When they decide to expand the theft to personal, I may well just delete everything.

    Maybe I just need a few months to pull back from many things, and figure out new ways of rebuilding. It means a financial hit, and it probably isn’t worth it to release a new holiday short this year.

    And I’ll do my out-of-the-box protections which are designed to have a ripple effect over time with serious consequences for assholes. No, I’m not going into detail. I will start using either Glaze or Nightshade for images.

    All of that took more time than I would have liked, but that’s the way it goes. Retrogrades slow things down.

    And, I noticed that when I was responding to comments on other posters’ IG accounts about these issues, when they replied to me, I could not reply back and continue the conversation.

    Really makes me want to delete all the Meta and just suck it up. I’ve successfully lived without the dystopian version of what used to be Twitter. I miss what it was at its best, not what it became.

    I’m going to lose touch with a bunch of people. I’m not doing monthly subscriptions to anything. Not because I don’t want to, but as a freelancer, I cannot commit to anything monthly beyond my bills when I never know when I will get paid. Bills must be covered first. Then I spend money locally and with individual artists. Even a small monthly subscription can put me behind, so I don’t do them. Not only don’t I want to live by subscription. I can’t. I literally can’t.

    I remember how devastated I was moving off Twitter. This just makes me angry. I’m not surprised, but I’m angry.

    I’ve never given up analogue everything – writing, music, etc. So it’s just time to hunker down for a bit. I’m selling books locally over the holidays at a few places. I’ll put sell sheets into the books, too, with information about the rest.

    And I need to find something for when the ghostwriting contracts are done, which will be fairly soon.

    Speaking of ghostwriting, I had a really good session on it, and I hope I can keep that momentum up. I even got ahead of where I hoped.

    I also read the scripts for tomorrow’s literary committee meeting.

    I was wiped out by then.

    I’m not one much for frozen meals, but I hate making lasagna (weird, I know).  I found a frozen lasagna by a company out on the other side of the state in Quincy, MA, so I bought one last week, figuring there would be days I wasn’t up to cooking post-booster. I slapped it into the oven last night and hoped for the best.

    It was actually pretty good. And my taste buds are working again, so I wasn’t imagining it. I would buy it again, and try their other products, and have one or two on hand for nights I can’t face the stove.

    I read a little bit in the evening. I’m caught up on all the library books, so it was time to dig into my own TBR pile.

    Went to bed a little earlier than usual but later than I have been, and couldn’t sleep. So I guess I’m getting back to “normal”?

    Finally got to sleep, only to be woken up when Willa pulled a Houdini and my mom couldn’t find her. We found her, got her back into my mom’s room, and I went back to sleep, and then overslept until 6:30 this morning to start the routine.

    The routine felt better this morning, even the yoga. I had a good free-write session, jiggling a lot loose.

    After breakfast, I will get a crockpot marinara sauce going, take out the garbage, pick up the mail, vacuum, get some writing done, and then switch over to the ghostwriting in the afternoon. I will take breaks as I need them, and not push too hard.

    My friend’s surgery went well yesterday. She has a long recovery ahead of her, but excellent care, and that’s always a relief.

    Have a good one!

  4. Protocol Upgrade Compatibility Review: Bybit


    Target Protocol: Bybit (TVL: $15557.9M)

    Protocol Upgrade Compatibility Review – Bybit


    TVL: ≈ $15,557.9 M (Ethereum + L2)

    Date: 25 Oct 2026

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

    1. Executive Summary


    Bybit has evolved from a centralized derivatives exchange into a multi‑chain DeFi ecosystem that includes a spot & futures DEX, leveraged liquidity pools, cross‑chain bridges, and L2‑optimised yield products. The platform’s rapid growth has driven a series of protocol upgrades (new tokenomics, governance modules, L2‑specific roll‑up integrations, and bridge extensions).

    Our Upgrade Compatibility Review focused on the interaction surface between existing contracts and the upcoming upgrade bundles, with particular emphasis on:

  5. Building an e-commerce application with React involves much more than displaying products and adding a shopping cart. A production-ready storefront needs predictable state management, responsive product listings, reliable cart calculations, accessible interfaces, and a checkout flow that customers can trust.

    In my experience, the biggest challenge is keeping the shopping experience consistent as users browse products, change quantities, apply discounts, and move toward checkout. React makes this easier by breaking the interface into reusable components and allowing the UI to respond automatically to changes in application state.

    In this guide, we will build a small e-commerce storefront using modern JavaScript and React-inspired component architecture. We will explore product data, cart operations, inventory validation, discount calculations, and order summaries while keeping the example simple enough to run directly in Node.js.

    Designing a Maintainable React E-commerce Application


    A maintainable e-commerce application starts with clear separation of responsibilities. Product data should remain independent of UI components, cart operations should follow predictable rules, and pricing calculations should live in reusable functions rather than being duplicated across screens. This structure makes features easier to test and reduces the risk of inconsistent totals.

    React components work particularly well for product cards, product grids, cart items, quantity controls, and checkout summaries. Each component receives the data it needs through props, while shared cart state can be managed with useState, useReducer, or a dedicated state management library as the application grows. For a larger storefront, Context or Redux Toolkit can help coordinate state across routes without passing props through every intermediate component.

    The following runnable JavaScript example implements the core business logic behind a storefront. It uses an in-memory product catalog, validates inventory, supports adding and removing products, calculates discounts and shipping, and generates a final order summary. The example runs in Node.js without external dependencies; its functions can later be connected to React components and backend APIs.

    One important production consideration is that the browser must never be the authority for prices, inventory, or payments. A real checkout should send product identifiers and quantities to a trusted backend, which retrieves current prices, validates stock, recalculates totals, and creates a payment session through a payment provider. The frontend should display the resulting server-confirmed order state rather than treating client-side calculations as proof of payment.

    /*
    * Minimal e-commerce business logic.
    * Run with: node ecommerce.js
    * This example uses in-memory data and no external packages.
    */

    console.log("STEP 1: Initialize the product catalog");

    const products = [
    { id: "p101", name: "Wireless Headphones", price: 2499, stock: 8 },
    { id: "p102", name: "Mechanical Keyboard", price: 3999, stock: 5 },
    { id: "p103", name: "USB-C Hub", price: 1499, stock: 12 }
    ];

    // Keep cart entries small: product ID and selected quantity.
    const cart = new Map();

    function findProduct(productId) {
    return products.find((product) => product.id === productId);
    }

    console.log("Available products:");
    products.forEach((product) => {
    console.log(`- ${product.name}: ₹${product.price}`);
    });

    console.log("\nSTEP 2: Add products to the cart");

    function addToCart(productId, quantity = 1) {
    const product = findProduct(productId);

    if (!product) {

    Conclusion


    React provides a strong foundation for building e-commerce applications because its component model encourages reusable interfaces and predictable UI updates. When product data, cart operations, and pricing rules are separated into focused modules, developers can introduce features without turning the storefront into a difficult-to-maintain codebase.

    The example demonstrates the fundamentals, but production applications need additional safeguards, including server-side price validation, secure payment processing, persistent carts, authentication where appropriate, error handling, and automated tests. Inventory should be reserved and orders should be created through carefully designed backend workflows, especially when multiple customers can purchase the same product simultaneously.

    My recommendation is to start with a small, working storefront and introduce complexity only when the requirements justify it. Build reusable React components, keep business rules testable, measure performance on real devices, and treat checkout security as a core requirement from the beginning.
