Still waiting for a plug-in power station installation at my home. Meanwhile charging car using public chargers is ~2x more expensive than driving on diesel. Btw. in Poland - where energy is mostly coal-based - petrol is more eco-friendly than electric.

Reading some several-paragraph long DM, that's clearly AI-generated based on my public Github + LinkedIn history, I feel at loss. I've already put more effort into reading it than whoever was writing it.

Something that I think @jetbrains.com RustRover should catch up to VS Code Rust extension - tooltip showing struct size, alignment and drop requirements.

Bodied by my eldest , frankly

If AI-driven programming will be here to stay, will programming languages start to optimise for lower number of tokens to be consumed by AI agents?

Tip: there's no difference between `SmallVec<[u8;8]>` and `SmallVec<[u8;16]>` in terms of struct size - both are 24B, same as a regular empty Vec. You can have 16 bytes for your inline buffer before container size starts expanding.

Actually a pretty good diagram

It's interesting to see that now - as Cloudflare lives through some rough times - how much of the Internet depends on it.

A: So, how's going? Me: www.youtube.com/watch?v=NBZv...

This is admirable pro-consumer move: blog.kagi.com/slopstop Kagi is also nice contrast to Google, which when asked for a LITERAL COMPANY NAME, doesn't even show it in first 3 search results.

Something that I hope more languages will adopt from F# is `and!` binding operator - used for marking independent expressions which can be used to i.e. auto-parallelise async calls or gather validation results: learn.microsoft.com/en-us/dotnet...

Took 4in1 vaccine shoot. Now I sleep in the middle of the day, have problem to focus on work for more than few hours and my back and joints hurt. So theoretically, nothing changed.

Everyone are talking about vibe coding. What about "vibe pricing"? You want to pay for AI tool. For $20 you get 1500 AI credits/month. But what is AI credit? What's the table to calculate your usage and needs? Nobody knows. Not even the authors.

I offer help for free, via email, to people using Redis Vector Sets in production or if they are experimenting with that. Feel free to ping me! If you don't know what I'm talking about, check this: redis.io/docs/latest/...

You don't appreciate stack overflow failures in JVM/.NET until you realise that in Rust it leaves no stack trace, so your production logs leave you empty handed when it happens.

State of the art of the software in 2025. Want to uninstall AI tool? Just follow the official docs they say (claudelog.com/faqs/how-to-...).

I managed to burn two laptops in my life: 1. I rented my free CPU time to SETI program for too long. 2. I run Linux on a Dell laptop with NVIDIA graphics card on board back in 2011 and went on a lunch break. Now I think, it's wild that I managed to do it twice.

This is a very nice blog post because it is not afraid to explain hard work in terms of simple concepts. go.dev/blog/greente...

Shit like that should be an eligible reason to return the product as part of warranty: arstechnica.com/gadgets/2025...

The romanticised Polish Golden Autumn has ended. This year it lasted for 5 days.

Call out to music creators on YouTube: don't use GenAI for your visuals. As a fellow artist, would you like to be replaced with an algorithm because someone else couldn't be bothered to reach out to you? If you are using GenAI for visual, why would I trust that music is made with your own effort?

This is impressive: an interactive step-by-step introduction to build LSM from first principles - www.nan.fyi/database

I guess AWS outage was the biggest advertising for local-first community in a while.

I'll try moving from Spotify to Tidal. Reason: it pays artists ~4x more and has option to import my Spotify playlist (only 3 out of 400 tracks were not on Tidal). Hopefully integration with the different devices -including car - will keep up with my expectations.

These two perfectly complement each other and cover two core elements of calisthenics (planche and lever): 1. www.youtube.com/watch?v=ngZq... 2. www.youtube.com/watch?v=u3fa... And if you have more time, you can also add (www.youtube.com/watch?v=3qfR...) (muscle up) for complete routine.

Task: "this function should work with any type that can return a &T". Rust: let me educate you on Deref, Borrow and AsRef. But if your type is hidden behind Rc<RefCell<T>>, Arc<Mutex<T>> or Arc<RwLock<T>>, you'll need to play a 5D chess match against your compiler to make it work.

Have anyone tried to implement Rope data structure over persistent key-value storage?

Some thoughts back from the vacation on African dessert: current world of software expects you to be permanently online and that sucks really badly. Even my music app and video player first hangs for a minute trying to connect before giving up and letting me work on it. This is unacceptable.

Why bother to read something nobody could be bothered to write?

put another way: i don't want your data—not just from an ideological "users should be in control" perspective, but from a pragmatic "this makes my app harder and more expensive to run" perspective we've been so focused on making it easy to scale up that we've accidentally made it hard to scale down

I'm looking up for papers about on-disk trie/radix/prefix tree-based key-value stores. I've heard about Cassandra switching some time ago (cassandra.apache.org/_/blog/Apach...). Are there any other good insights into these data structures?

Idea: have a Rust bytes::Bytes<T> variant, where T describes how to interpret its binary content, ie.: - Bytes<Utf8> - Bytes<Lz4<T>> - Bytes<ZerocopyStruct> this way we also never assign incompatible data like `Bytes<Lz4<T>> => Bytes<T>`.

Looking at the state of cargo crates related to immutable/persistent data structures (some having < 300 downloads, most not updated for 3+ years), I'd say that this domain pretty much died in Rust ecosystem.

My favourite part of Akira is that its portrait of the fallen, post-apocalyptic youth looks basically the same as in a regular US high-school drama from the 90's.

Well, depends heavily if you have or don't have the money. If you fund your venture out of your own pocket you better have a very good reason for spending a sum of money PER YEAR for which you can establish an entire elementary and high school in Europe including building the campus.

You can easily find stores to buy alcohol 24h/day, yet pharmacies with such availability are so rare...

New level unlocked: copilot autocomplete started adding features that don't exist in the language (in my case: adding function params with default values in Rust :) ).

Ok, so iPhone Air has bad battery, doesn't support physical SIM cards or 5G. And USB 2.0 charging port... Who is this shit made for?

Reading HN comments on "Why Local-First Apps Haven't Become Popular?" to discover that 90% of the readers don't understand what local-first (or local-only tbh) actually implies.

SIMD Within a Register: How I Doubled Hash Table Lookup Performance Learned about SWAR the first time in the one-billion row challenge. Nice explanation including benchmarks.

Fuck me this is bleak. But please, do continue to use GenAI slop thumbnails for your YouTube videos, or your album art, or your book covers or whatever else. I'll continue to refuse to watch/listen/read any of them, knowing already they're not worth the time & that you're a disappointing lazy hack.

While atm. bitchat already supports BLE, there are also plans for WiFi Direct and... low-bandwidth ultrasonic communication in case when you wanted to chat in environment where radio signal is jammed or dangerous: github.com/permissionle...

I tried to watch National Geographic movies on youtube, but with my current level of ADHD, these are barely watchable. They're 40+min videos that hide maybe 10-15min of actual content. The rest is just repeating the same facts and building shock/suspension narrative.

Why would I care if new iPhone is even thinner, when I still need to somehow sit with 6.5'' titanium rectangle in my pocket?

TIL that Fossil (SQLite internal version control system build on top of SQLite) has a chat feature - which supports Markdown syntax including table and diagrams rendering: fossil-scm.org/home/doc/tru...

Tbh. I wanted to move my private repos out of Github. And as I'm on that, I'd like to give some other vcs a chance - I think, I'll go with Fossil.
