FKVS is a tiny, high‑performance key‑value store written in C (with no dependencies) with a single‑threaded, non‑blocking event loop. It is part of my experiment to understand what it takes to build a key value from first principles. github.com/AlexJuca/fkvs

@BenjDicken Go for its simplicity, concurrency model and overall good perf. I say this but I really like Zig.

You can only build software in one for the rest of your life: Go Zig Rust What are you choosing?

Microsoft is Vibe coding hard

@OneBadDude_ Africans! They love violence. They are like animals. Send them back to Africa where they can destroy their peoples cars!

This is why you don’t get in front of a vehicle! I do NOT think he will be doing that again! Dude lunges at a vehicle in a parking lot, breaking the back windshield. He then proceeds to kick the vehicle and challenge the driver to a brawl. The driver gets out for a minute and has words with the attacker before getting back into his vehicle to drive off. The man then steps in front of the vehicle as the driver floors it, giving him a ride on the hood of his car for the length of the parking lot. Play stupid games……

He's very good at what he does.

Since @OmarchyLinux ships with Waybar's calendar tooltip disabled, instead of simply setting "tooltip": true, I decided to build one that fits Omarchy. It's called waycal.dev, a tiny Waybar calendar popup for wlr-layer-shell compositors. It ships with a rounded style too, if that's more your thing. Written in Rust, btw. Available from: - AUR: `yay -S waycal` - Crate: `cargo install waycal` - Source Code: github.com/ForrestKnight/…

@JustJake @danielbergholz Nice work. The last 5-ish have been better. Thanks for paying attention to this.

@0xFFA4 @danielbergholz We’ve rolled out a LOT of changes here Any instability, regardless of users/impact/etc, has our full attention To smoother sailing onward 🚄

What is the best platform for deploying Elixir + Phoenix apps? I've been using Fly but Railway is looking nice 👀

@prowlerearth42 His the Minato of this generation.

Ngl after reading Boruto, I just realized that we don't really talk much on Boruto's battle IQ which I considerably think it's much higher than that of Naruto. Bro was still able to land a Uzuhiko to Jura even while still trapped by some spiky deadly trees.

@PajosTM Beautifully explained.

I was in class last week. One of my students raised their hand mid-lecture and asked something that stopped me for a second. "Why is every AI tool built on Python? C++ is faster. Rust is faster. Even Java is faster. So why Python?" Honestly it’s a fair question. And the answer reveals something really interesting about how the AI industry actually works. Let me explain this properly. 🧵

@antoniolupetti Thank you for bringing this into the world.

I’m honestly still a bit surprised by the long wave of attention Algebrica is getting these days after going viral on X. I didn’t expect this and I’m really grateful for the support. Many of you have left thoughtful comments and suggested edits. I review them one by one and they’re already making the content clearer and more precise. At the same time, I’m realizing how many things still need fixing. Small inaccuracies, gaps, things I simply didn’t notice over the past 2.5 years. So for the next few weeks I’ll focus more on improving what’s already there. Algebrica is a personal, free project. I work on it alone, in my spare time, so it will take a bit to go through everything. But I will. In the image, the markdown editor used by users to suggest edits. Simple and immediate, just a bit of LaTeX and markdown... it’s not exactly a masterpiece of code but it works🙂

@psantos_ao Salário mínimo nacional 100 e tal mil kz Claude Code Max: 100 USD Vou comer ou vou usar IA?

@hkakutalua @psantos_ao A falta de dinheiro não muda a natureza humana. 😌

@psantos_ao "Existem indústrias que ainda hão de ter consumidores, apesar da classe média diminuir" Tipo a indústria de casamento em Angola @0xFFA4 😆?

@NoahKingJr The calculator cannot replace a human. The calculator has no goals, no agency. AI? Same thing.

Software Engineers what's your plan B if AI replaces you?

just use tmux and run whatever you want to run inside it and yes, there's a sidebar too

This is a page from Algebrica. Now enhanced with user suggestions directly in each section. Minimal. No ads. No noise. Just content.

@antoniolupetti This is great stuff! Thank you Antonio!

@prowlerearth42 I think the hate Sasuke felt for what his brother did and being the "last" surviving member of a murdered clan is tragic but on the other hand being abused and sold by your own father for money to a evil monk is tough too. It's hard to compare suffering.

Between Kawaki and Sasuke who actually Suffered More? 😭🙏

Database table size impacts performance in more ways than one: a) B-tree depth. Using 8k pages and a 16b uuid: 1 level = ~370 rows 2 levels = ~138k rows 3 levels = ~50m rows 4 levels = ~20b rows The lookup cost on a table with 100k rows is not the same as one with 1b rows. This can apply both to the table itself (MySQL cluster index) as well as the indexes. Sometimes a single query requires many of them. b) Small table → fits in RAM → fast reads. The larger the table, the more likely to read from disk plus churn the cache. c) # of indexes. Each adds maintenance overhead for insertions, and for Postgres vacuum overhead as well. Keep an eye on this! It's useful to take regular stock of your tables + indexes. Clean bloat. Remove unused indexes. Partition if needed.
