• Your best users are the ones who complain. A user told me at 10pm that my uninstaller just nuked his shell config. My instinct was to get defensive. Instead I traced it — and found it was worse than reported. That one message led to rewriting the entire uninstall logic from scratch. Every angry bug report is a gift.
• Your favorite metric can lie to you. I built a cache that reduced file reads from 2,000 tokens to 13. Great numbers. Then a user told me: "Models waste more tokens working around stale cache than the cache saves." He was right. The fix wasn't removing caching — it was making invalidation smarter. Your dashboard can look great while the experience is terrible.
• Saying no is the hardest part. A new feature would have let me compress all tool output automatically. Massive savings on paper. I designed it, prototyped it, then killed it. Because when compression eats an error message, there's no undo. Protecting quality beats shipping features.
• Community is a relationship, not a channel. When someone reports a bug, my first response matters more than the fix. "Will check" buys time but shows I'm listening. Following up shows respect. Shipping the fix shows they matter. My best testers are people who once filed angry reports.
• Ship the boring stuff first. Nobody cares about your adaptive entropy-based compression algorithm if the installer breaks their dotfiles. Get the fundamentals right — install, uninstall, doctor, setup — before you get clever.
• Focus means killing good ideas. My backlog has 50+ ideas. Each one is good. But spreading across all of them means none become great. Rust helps here — the compiler forces you to finish what you start.

The native applications lost the battle.
Windows is not able to offer a consistent native UI over a decade.

The UI inconsistency in Linux was created by design.

MacOS is no longer the safe heaven where designers can work peacefully.

Electron Apps have , but they also lack off visual consistency and keyboard-driven workflows.

Some restartet from scratch with Dart and Flutter UI to replace Android legacy things. Google gave up because they needed a monopoly or a large enough market to succeed.

Zed did the same thing in Rust: they designed their own cross-platform GPU-renderer library. It lacks integration with the host OS on itself though.

On the contrary, TUIs are fast, easy to automate and work reasonably well in different operating systems.

Based on the example of Russmedia: how does the fediverse blocks a content?

Build a web of trusted domains to avoid or detect AI slop

A quick prototyping tool: why should AI be used when you can do it quickly :D

A script checking all NPM dependencies that have a commit from Claude AI in their 100 latest commits.

It will only ping the GitHub API thought. So dependencies hosted elsewhere won't work.

We can use the oklch (OK L C H) and adjust the lightness and chroma from the hue, thus generating colors.

Creating colors from oklch is tedious, but they can derivated from other color codes from [#007ab8](https://shaarli.lyokolux.space/./add-tag/007ab8) calc(l - 0.05) c h)

Tip: very light and very dark lightness levels have a tendency to look oversaturated.. a lot of color palettes look more cohesive when you reduce the chroma slightly as you move away from the middle-range of lightness towards the edges.

Example: https://codepen.io/cferdinandi/pen/zxoYpeL

This example is good for dynamic colors.

This document specifies a network-layer protocol, IPv7, that extends
the Internet Protocol model with an identity-carrying address form
and an origin-validation mechanism intended to mitigate abuse of
residential proxy infrastructure. IPv7 replaces purely numerical
source addressing with a hierarchical identity string and a Variable-
Length Identity Block (VLIB) that carries an Ephemeral Identity Token
(EIT), provider and tenant identifiers, role/policy signalling, and
an Origin Signature verifiable by the originating provider. The
protocol enables routers to apply policy and reputation signals at
the network layer while limiting disclosure of a subscriber's long-
term identity to intermediate systems. This document addresses
growing security challenges in Internet-connected devices (IoT),
including smart TVs, appliances, and other residential endpoints that
are vulnerable to residential proxy exploitation and botnet
infection.

Generate anything related to security. It can't be used for serious project though.

Lichen is the simplest possible CMS for the web that is friendly enough for non-technical users. Comprised of just a few Forth CGI scripts, it is extremely lightweight. This site is built in Lichen. It can also be used as a static site generator.
