  What's the point of using smarter models if "smarter" means 10% better at finding obscure bugs and having a sassy attitude? Most of the true productivity gains that coding agents have to offer, which are finite, can be obtained using open-weight models for literally 1/100 of the price. The catch is that you actually need to understand the code you are working on. At the same time, I still think there's a viable business serving proprietary models. People are willing to pay for Dropbox even though FTP is free, and it's nice to throw a tough problem at a stronger model occasionally (if intellectual property limitations allow it). Plus, there's a whole frontier productizing this stuff. Unfortunately, Anthropic is currently in the business of spreading tall tales about future improvements, then shaking down enterprise customers. Most of it is based on 2010s LessWrong posts full of category errors, some of which I remember reading back in those days. And their recent hostility toward users in the name of safety is a result of the same ideological recklessness.

  track back to just over a year to now. i'd built an automated ecommerce flow that took a whole store end to end. seo would research trends, products, and map those into .js scripts which would launch prompts that read those research files. that would feed an image gen prompt which created designs, set to specific standard. i'd generate them, and then ANOTHER prompt, would check the images, score them with a criteria, and either move them to an accepted folder, or move them to an archive folder. the accepted folders, would automatically fire a script which would open photoshop, map the image to smart layers, in a 'product shot' template i'd made, and then export all of the final product shots to another folder, and then exported the flat designs which would be used for the products. another script took the product images, did visual lookups, generated all product descriptions, renamed the images and generated the seo text. it ran optimizations locally via a jpegoptim and oxipng script. it then uploaded them to dropbox, and via API, would generate a dropbox link map. i had one barebones csv template, which i'd run a ps1 script through to map json files into the csv rows, and insert the dropbox link map. all my images, links, followed the exact same slugs, so it turned 2 hours of manual work into a 5 second bulk rename and insert. it then converted that csv into json, which then itself converted that json into ld-json for product rich listings. ai would write the product description based on a dataseo keywords, and googletrends json file that would run on every product type. collecting keywords for that specific product. it also formed it around brand profiles, copy guides and other things. this was sonnet 3 days, GPT 4.0 days, and it STILL wrote great copy when it had the right guidance. in the .js file, i'd replace all em dashes with a hyphen if they ever appeared. i built a custom product uploader, built my own php plugin which synced to local .js files and connected via rest. it was (and still is) one of the best wc product uploaders that exist, as it completely resets filterlookups only for that product, and is lightning fast because i upload it directly into woocommerce rows from json. no importers, no wordpress malarkey, or WC rest needed. it was 50x faster than wc's own CSV import. the images would be uploaded via ftp, and then on detection, would sync those to the media library, and i'd upload the image meta from the seo run, so they all had captions/alt text etc. it took what would be 3-5 hours of manual work per product, and congested it into a 2 minute image to fully live product system. after that, i'd export sales data, the ai was constantly learning, sales data feeding back to files, which would then teach the ai what products work, what doesn't. what copy worked, what copy didn't. that would then flow back into the original source files which told the ai what images to gen and what products to launch. all of it was local on my pc. i wasn't selling an saas. it was just something that worked for my very particular setup. the thing about it is; i built that mostly with GPT 4.0 and a little bit of 3.5! mostly copy and pasting code manually from the chats in chatGPT. all the plugins, the php, everything. then some of it got improved inside vscode back on the old original copilot plans, when $10 used to last you an entire month of none stop coding. this was before n8n, before agents were even a thing. all of that I built very specifically for myself, local, syncing folder to folder, json file to json file. python scripts watching files, and .ps1 files that would follow up with other .ps1 files, which launched .js files which contained prompts for AI, and hitting the openAI API's whenever I needed the AI layer. eventually i built a terminal tool, which would allow me to run the scripts from the terminal, and i'd manually type in the slugs for which products i wanted processed. all files would sit in specific folders, and scripts would do the rest. i was so excited about that, giving my terminal app a shortcut icon and putting it onto my taskbar. that was a year ago. fast forward to now. the game has changed so much. ANYTHING and i mean anything is possible now. people 'new' to codex, and CC etc don't know how good they have it. but i've had this ******* idea for so long, to build a fully automated, self learning ecom business, that launches products end to end based on it's own research, writing, and growth, but the complexity of it previously , and being busy with life, it never got finalized. the secret is i sync it via etsy too, but they're API keys take FOREVER to aquire, but built my own etsy system, product uploader, which runs across 7 different stores. however, now, i've finally been building the replacement for it. i'll be able to run that exact same system, except this time through a full app, with a canvas, and agent systems instead of .ps1 scripts. not to say i won't run scripts; they're an integral part of any automated workflow, but now it has superpowers, and it can do so so so much more. all the ideas I wanted to do, automated, fully, end to end. not only that, but i moved away from woocommerce entirely. instead i just built my own website builder, which is also fully automated end to end. my brand profiles, my artwork system? i'm still using those, just for more things. now i can launch 50 brands just like it, running the same system, all in about 5 minutes. whether it's saas, local service, or online ecom. i also built an ai automated ad builder. it takes my brands images, or generates images. i've got background removers, and full skills and agents which fully generate the ads for me. it mixes all that into seedance videos, and posts in logos etc. now i take those image/videos, and build instagram, tiktok, facebook vids, generate descriptions, and upload them automatically. it has an every growing library to source from, templates to use, and the system derives right with the websites, so all themes/styles match precisely to the brand. this is why it's so great building for yourself. the amount of reusability you get with it, the fact it's free forever, can never be beaten. none of these saas companies get it. and they're heading in the wrong direction. we could already DO half of what these companies are doing. my own personal SEO system, which i built for my automated web builder, is already 10x better than any yoast, rankmath etc. i skip expensive ahrefs, semrush, and just rebuild their services myself, using API, which is 100x cheaper. except this time it FEEDS my system, and i don't need to lay a finger on it. nobody cares about these little one off apps that won't exist in a year. they're either failing to see the future, or they're hoping for an early exit before they know the dominos start falling. people will want PRIVATE systems. all speaking to each other. not 1200 integrations and 1200 invoices to send to, that don't even have a ******* brain. i'm not selling anything yet. but if you're interested in seeing how i think about automation, then stay a while and listen. the tool i'm building will absolutely help you too. but i'll be honest. i'm actually quite scared to release it, solely down to how powerful it is. not many people do it like i do, and i'm finally on here to tell the world.

  Dropbox is where deals go to die. Investors open your “data room.” It’s a shared folder named “My Data Room” with 34 subfolders and zero logic. They close it in 8 seconds. You never know they were there. No analytics. No structure. No story. That’s the problem we built @ThePageform to fix.

  @Dropbox I’ve been dealing with an issue for a few weeks now, and your AI customer chatbox has been unable to resolve it. It keeps looping through the same troubleshooting steps that haven’t worked, and I’ve already spent over three hours on it. "It looks like our chat has wandered into areas I'm not equipped to handle effectively. Unfortunately, I can only help with Dropbox-related questions, and I'm unable to help you with this topic." I’ve been a customer since 2009. It’s disappointing to reach this point, but this level of support is unacceptable.

  Then the conversation took a turn. The technician pulled up Activity Monitor and showed him something: 23 apps were running in the background that the customer didn't have open. Adobe Creative Cloud. Spotify. Slack. Microsoft AutoUpdate. Dropbox. Google Drive sync. Three different "helper" apps installed during printer setup years ago. Each one was consuming small amounts of CPU, RAM, and battery cycles 24/7. The technician's words: "Your MacBook isn't slow because it's old. It's slow because it's running 23 jobs nobody hired it to do." System Settings → General → Login Items → look at the lists under both tabs → remove anything that doesn't need to launch automatically. The customer removed 18 of them on the spot.

  Open your bank statement right now. Count every subscription. Netflix. Spotify. ChatGPT Plus. Claude. Adobe. Apple One. Disney+. iCloud. YouTube Premium. Audible. NYT. Dropbox. Notion. Gym. Dating app. A 2026 study found the average American spends $219 a month on subscriptions. That is $2,628 a year. But they estimate they spend $86 a month. 74% of people admit they have forgotten about a recurring charge. 42% are currently paying for a subscription they have stopped using. A Portuguese developer named Miguel Ribeiro got tired of bleeding money to forgotten subscriptions. He lives in Berlin and works as a senior frontend engineer at eBay Kleinanzeigen by day. At night he tried Billbot and a bunch of paid web apps. None of them worked. Some of them charged him a monthly fee to track his monthly fees. So in October 2023 he wrote his own. The repo today: → 7,922 stars → 365 forks → GPL-3.0 licensed → Pushed last week → 69 followers on the founder's profile It is called Wallos. You self-host it. It tracks every subscription, every renewal date, every category, every currency, and shows you the actual number on one screen. Here is the wildest part: The subscription companies designed the system this way on purpose. 72% of people set everything to auto-pay because the checkout flow defaults to it. Cancellation pages are buried 5 clicks deep. Some require a phone call during business hours. A 2022 FTC report called this "dark patterns" and Adobe is paying $150 million in a settlement for hiding cancellation fees this exact way. Miguel did not raise venture capital. He did not write a Medium post. He did not go on a podcast. He shipped one PHP app from his apartment in Berlin and now thousands of people use it to claw back hundreds of dollars a year. The honest part: It needs a tiny server (a $5 Raspberry Pi works). You have to enter subscriptions yourself, it does not auto-detect from your bank. The UI is functional, not gorgeous. The author still works a day job and ships updates in his spare time. Berlin. One developer. The companies that auto-charge you forever finally have an enemy.

  Windows 11 June 2026 update, which was supposed to make PCs faster, is crashing some PCs with BSODs, breaking OneDrive integration in File Explorer and custom folder icons, and causing other problems. We're seeing reports that Windows 11 KB5094126 is causing boot failures on some PCs, mostly HP enterprise hardware. The worst reports involve BitLocker recovery loops, Black Screen of Death/BSOD failures, Secure Boot signature errors, and error 0xc0430001. Affected models appear to include HP EliteBook 840 G10, HP ProBook 460 G11, HP Engage One Pro G2 AiO POS, HP ZBook, and some Dell Precision systems. The likely trigger is Secure Boot certificate handling + EFI partition space. On older images with a 100MB EFI partition, Windows may fail to update Boot Manager because there isn’t enough space, especially on HP systems where firmware recovery files can bloat EFI. There are also File Explorer cloud integration issues. OneDrive, and in some cases Dropbox or iCloud Drive, may stop opening from the sidebar/tray shortcut after KB5094126. Microsoft also confirms desktop.ini hardening can break custom folder icons or localized folder names from untrusted sources. KB5094126 is important, as it fixes 200+ security bugs, but be careful, as it could cause havoc on some PCs.
