Ok, I finally managed to build my own FPV ground drone from a Pico W, an arducam, and Lego parts. Everything is wireless and powered by 9 AA batteries! As usual, I'll write an article and publish the whole code (both embedded and backend are 100% #rust).

There's a fun bug in the #gemini chat. It sometimes ends its answers with what looks like leaking HTML, eg `</K,></K,>`. I just understood that the chat is "closing" what it interprets as opening tags, in Rust code which goes like `HashMap<K, V>`.

The end of a Gemini answer, with </K,></K,>

#LLM companies, especially #Anthropic, are playing a dangerous game with adaptative thinking. If they become stupid when the question looks simple, their value drops. Reliability beats medium quality. Here, Claude Sonnet 4.6 thinks 20 < 69 < 54.

My question to Claude:

Je suis à Lyon. Quelle est la date limite de déclaration de mes revenus ?

14:17
Claude responded: Lyon se trouve dans le département du Rhône (69).

Lyon se trouve dans le département du Rhône (69). Voici les dates limites qui vous concernent pour la déclaration des revenus 2025 :

Déclaration en ligne : le 28 mai 2026 à 23h59 Le département 69 (Rhône) appartient à la zone des départements numérotés de 20 à 54.
Déclaration papier : le 19 mai 2026 à 23h59 La déclaration papier est acceptée si votre résidence principale n'est pas équipée d'un accès à Internet, ou si vous n'êtes pas en mesure de déclarer en ligne.
Ministère de l’Économie
Le service de déclaration en ligne est ouvert depuis le 9 avril 2026 sur impots.gouv.fr.
Info.gouv.fr

En résumé, si vous déclarez en ligne (ce qui est la règle générale), vous avez jusqu'au 28 mai à minuit.

In a Kapla Binary Tree, the cost of adding a new level is exactly twice the cost of the previous level addition.

A construct in Kapla, looking like a binary tree, with 3 levels and 21 Kapla.

Naming unconsistencies in Rust are one of the main reasons I always have to look in the documentation. Why isn't it called push_slice ? Why ?

A table comparing the way a &str is pushed to a String (with push_str) and the way a &[u8] is pushed to a Vec (with extend_from_slice).

Random #rust tip: Did you know that by hitting ctrl-j you can see the list of jobs and their bindings in #bacon ? BTW this menu is customizable and I had totally forgotten about it to the point I pondered about adding the feature...

The small project I started in order to learn Rust, 7 years ago, isn't quite as small today. #broot now has 100 contributors.

Interesting approach. When derives don't fit the line, I would prefer being able to do this but it doesn't play well with rustmt unfortunately:

Crates.io download *can* provide insight. Guess which #rust crate is used mostly at work and which one is also used on side projects.

The download graph of two crates: bacon and lazy-regex. The one of lazy-regex differs by having almost no downloads on week-ends.

Type inference in #rust isn't always obvious

How is it even possible in 2024 that a social network doesn't allow embedding code ?

Parsing enums in #rust is so much cleaner and easier to maintain with regex_switch. Yes I'm bragging but also you should really use lazy-regex ( github.com/Canop/lazy-r... ).

Some rust code:
- an enum, with some variants holding fields
- a FromStr impl based on the regex_switch! macro

dystroy @dystroy.eurosky.social · 24/07/2024

I'm adding the regex_switch! macro to lazy-regex: a switch like alternation with variables declared from the named capture groups. Of course all regexes are lazy static and checked at compile time. Feedback welcome. github.com/Canop/lazy-r... #rust #regex

A screenshot of some code, an example of using regex_switch!, which is also (as text) in the linked PR.

I just released version 2.15.0 of bacon, the #rust background compiler. It's quite major but the little change I want to promote is a more helpful --help with main shortcuts and examples. dystroy.org/bacon/

No #Copilot, you stay with me, you're not allowed to quit.
