#SkybearNET Insights documentation📝 www.skybear.net/docs/feature... I just documented the new Insights dashboard for SkybearNET. Check out what you get out of the box across all your tests, and more are continuously added. Hundreds of requests, thousands of asserts, each run.🤯

> We've been profitable from month one – every single month for 20 years. That consistency has given us the freedom to make decisions based on what's right for our customers and our family. The dream. Hugely inspired by your journey, Ian. It’s something I’d love to have for myself one day.

Those benchmarks from @t3.gg revealed some interesting issues in Workers. Happy to say it's all fixed now, save for some lingering next.js-specific stuff we're continuing to work on. Thanks for the reproducible test cases, @t3.gg. Excessive details in blog post: blog.cloudflare.com/unpacking-cl...

Next project: AI agent for investing. Based on my own preferences and criteria for company fundamentals, combined with some trend following technical analysis and breakout detection from pivot points. An MCP server to allow me to chat with the agent through LLMs, and web UI.

I still need to get better at this.

I started reading software blogs before I got my first programming job 20 years ago. At this point, I’ve read thousands of blog posts and essays about software, but only a small handful stuck in my mind and changed the way I think. refactoringenglish.com/blog/softwar...

I have been listening to the Market Wizards books by Jack Schwager and I loved them. It does make investing and trading seeming like a skill that needs a lot of work, consistency, patience, and risk management. However, not a single strategy is best. It depends on your character.

Reliability is sort of like a stomachache. It’s hard for people to really appreciate not having issues until you have issues.

Share your best resources, articles, publications, talks, about "AI in Databases and Storage products". I imagine some applications are for query optimization. What else is already being explored or would benefit from AI? Infrastructure or application level.

Finally updated the #SkybearNET landing page with the Insights feature that's been out for several weeks, and some stylistic changes. New pricing as well.😉 www.skybear.net

I mentioned a few times that DynamoDB is among my favourite databases. I collected my favourite articles, videos, and its papers into a single place. Great to go through and learn the internals of DynamoDB. Let me know if I missed something. www.lambrospetrou.com/articles/dyn...

BlueSky wants me to verify my age (seems to be a new UK law), and the provider they use failed at least 4 times today in different times. If you force a check on your users, make sure it works first.😮‍💨

"Investing in 3x Daily Leveraged Nasdaq 100 ETFs (TQQQ or QQQ3) using QQQ weekly MACD signals" 💸 I have written down the strategy I have been researching and backtesting over the past few months. I wish history repeats.😅 www.lambrospetrou.com/articles/inv...

Future in 20XX. Custom UI (websites, apps) doesn't matter anymore, at all. All devices directly handle multimodal input, and based on "intents" the service's APIs are called, and the response is converted to visual/audio/feeling (e.g. vibrations). Hardware + APIs + Data, wins.

😎 Super happy to announce Hurl 7.0.0! ✅ better ways to checks every step of redirections ✅ new filters to templatize HTTP request and response ✅ new curl options supported, --max-time / request, --ntml, --negotiate, --pinnedpubkey => hurl.dev/blog/2025/07...

Assuming you have an initial capital of 200K USD. What gets you to at least 2 million USD in the bank faster and more probable? A) Investing/Trading vs B) Building a business (3y+ horizon)?

“$110M a year on AWS? I could do it for half!” Bro, your last infra project was making a cron job email you weather updates. Sit down. www.duckbillgroup.com/blog/figmas-...

"As AI expands, the real opportunity is to find a way to use human effort to create more value. [...] What we do have is agency over how we’ll thrive in a world where human work is being redefined. Either you work for an AI or AI works for you." seths.blog/2025/07/prod...

I am a hard core fan of Claude 4 and Claude Code, but using jules.google.com for easy changes without having to leave the browser is super nice too! Need to set up my remote access to Claude Code through Tailscale, but Jules is sufficient for quick things.

I decided to record a talk on agentic programming and why I'm so damn addicted to this. I think there are a few useful things in it, but I'm sure in a month this will be outdated :) www.youtube.com/watch?v=nfOV...

"Logistician - ISTJ" sounded wrong initially, but the more I read about it, the more it fits me. I expected the "Architect - INTJ" type, and in hindsight I can even trace back to the questions that probably tipped me over. I find this personality test not to be very bullshity.😅

I love these simple and fun sites. Would pick one over those purple gradient websites any day. pointerpointer.com

Since you cannot do any work, visit www.skybear.net and let me know what you wish an HTTP Synthetic testing platform should offer in addition to that.😅

"The Gap Through Which We Praise the Machine" ferd.ca/the-gap-thro... by @ferd.ca I agree with this criticism of the LLMs and how they are hyped for magic when it actually needs effort and training to be effective.

Some recent experiences programming with agents. crawshaw.io/blog/program...

New toy, MSI Summit 13 AI+ Evo. This is a beautiful machine! The build is really good, feels premium, with an amazing keyboard! #2in1 #laptop

"Always use Postgres" 😅 The database where removing a JOIN leads to 250x query execution time improvements. Mostly half joking here, it does its job well, but it always needs extra work at scale.

I am not a fan of Rust (yet), but this post is really good describing Rust usage while building Aurora DSQL. "Just make it scale: An Aurora DSQL story" www.allthingsdistributed.com/2025/05/just...

Drafting xkcd.com/3093/

Dive into the architecture and design of DSQL, starting with Werner's new blog post (with Marc Bowes and Niko Matsakis): www.allthingsdistributed.com/2025/05/just...

I have been using @kagi.com with Claude 4 Opus for several days now to implement and iterate on several investing strategies using Trading View PineScript. Over time I extended my system prompt and now it spits out scripts exactly in my coding style, explaining them perfectly. #ToTheMoon 🚀

🔄 Just revamped Litestream! Our open-source SQLite tool now features faster point-in-time restores, conditional writes for S3, and lightweight read replicas. Perfect for modern deployments without changing your code. Even AI coding agents can benefit! ⚡ 🔗 ➡️ fly.io/blog/litestr...

This is the best thing written about monorepos I have ever read blog.swgillespie.me/posts/monore...

Wicked features. www.seangoedecke.com/wicked-featu...

✨ It's new samwho visual essay o'clock! ✨ Reservoir sampling is one of my favourite algorithms. It allows you to sample from a set without knowing the size of that set. I try to assume no prior knowledge, and use no scary math notation. Just beautiful visuals. Let me know what you think! ❤️

Added a page on my site with the best LLM prompting guides and practices: www.lambrospetrou.com/articles/llm... Share your favourite resources that were useful for your prompting in the comments!

Very interesting concept to use Github (issues, github actions, pages) to power every part of an uptime monitoring service. No servers to manage.😅 github.com/upptime/uppt...

Starting a new project. What are the best AI models for semi real time audio/text processing? I need fast responses (less than 2 seconds), and I will handle providing the right context and how often to call them. Send me things to read. ;)
