This is a must-read for learning how scalable vector indexes work. @vmg is one of the best writers in the tech world.
Vitess databases on PlanetScale support sophisticated vector search. We've published a deep-dive by @vmg on how we built this for MySQL in a way that is scalable, performant, and ACID-compliant.
If you're interested in open source and don’t know how to get started, I wrote a series of articles on the AppSignal blog to help you learn how to read and understand the source code of Rails Engines. Here is the first article 🎉👇

Tuesday morning is a good time for open source. At JetRockets we use @rails @tailwindcss @ViewComponent, and StimulusJS as our default front-end stack. Time to contribute back. We created a sample Rails 8 app with the collection of UI elements we use daily, pushed it to GitHub,…
I think this is a great resource (book), it covers the more modern Linux kernels. Available as a PDF too. He also has YT videos accompanying the book. Operating Systems: A Linux Kernel-Oriented Approach - Smruti R. Sarangi cse.iitd.ac.in/~srsarangi/osb…

How long was the last video series/course you watched all the way through and really enjoyed?
The iconic Google Bigtable paper. On the technical side it left me wanting more. I *loved* the last few pages though. Performance analysis and real-world use cases for Google Analytics, Maps, and personalized search. More orgs should talk about their internal tech and scale!
The five-part memory profiling blog series is a great read - save and share. easyperf.net/blog/2024/02/1…
📚 Performance Analysis and Tuning on Modern CPUs by Denis Bakhvalov is a great read in the context of detailed designs of the CPUs. products.easyperf.net/perf-book-2
The AI Engineering book from @chipro is GOAT. But I didn't realize its repo has a goldmine .md of the resources she used to write the book. These are papers and blogs you can use to learn about making LLM apps, prompt engineering, fine-tuning, RAG, and much more.
Let’s talk about Inertia Rails patterns beyond basics: partial reloads, modals, forms, type safety, realtime with Action Cable. It’s ready in the new amazing post by @skryukov_dev 🙌 on Martian Chronicles: evilmartians.com/chronicles/sim…
Proxmox is such a great tool for testing Omarchy and Omakub releases. I just have a bunch of snapshots at different versions and times that I can upgrade to verify that stuff works. All powered by my lovely Minisforum A2 home server and accessed via @tailscale from wherever!
@tejaswi_surya gifted our PM with Sri madacarya Sarva moola grantha in digitized format today! Tejasvi Surya Fantastic to know this Tejasvi Surya. We have a MadhwaGPT based on chatGPT 4o training model chatgpt.com/g/g-67a39378e5… already in production. Give it a spin when you have…
Hey @grok, I have a hard time understanding the Cache-Control header. Prepare a flowchart that helps in choosing the correct directive based on the application requirements.
