TIL: how to change playback speed in QuickTime on Mac: run the following command from the terminal 🤦‍♂️

osascript -e 'tell application "QuickTime Player" to set rate of document 1 to 1.2'

iOS aplikace od @RegioJet má fakt debilní UX 😠 Právě jsem si omylem koupil tři lístky místo jednoho. Těsně před odjezdem vlaku, takže nejdou vrátit 👎

After enabling `mocha --parallel`, our test suite duration was improved from ~3.5 minutes down to ~1.5 minutes. 💪 Thank you @b0neskull for implementing parallel test execution in Mocha, the feature makes a real difference!❤️

TIL: in iTerm2, font ligatures are rendered using CoreText, which is significantly slower than Core Graphics; ligatures are also not supported by the GPU renderer, which is also much faster than the legacy renderer.

Repeat after me: blockchain is centralised.

You want to tilt the power dynamics to favour social justice? You don’t do that by making a billion copies of the same database. You do it by ensuring that a billion people can have their own unique databases.

Expend your energy to realise topological decentralisation not global proofs. Sure, it won’t make you a billionaire but if that’s what you want, what the fuck you reading my feed for?

Peklo zmrzlo. Golang dostane generické typy!
Škoda, že ostrá verze bude dostupná nejdřív koncem roku 2021.

We are in the process of reorganizing LoopBack documentation to make it easier for our users to find the content they are looking for. Watch my newest screencast to learn more:

Pro tip 1: Screencasts are easier to record in small chunks, you can put them together later in a video editor. 💪
Pro tip 2: After taking a break, remember to put on the same shirt 🙈

After IBM stops offering their facial recognition SW for mass surveillance, now Amazon bans police use of their facial recognition tech. Time to ban facial recognition in public spaces! That's what I call for in my draft opinion on AI use by the police.

ShareDrop allows you to transfer files directly between devices, without having to upload them to any server first. It uses WebRTC for secure peer-to-peer file transfer and Firebase for presence management and WebRTC signaling.

In my latest blog post, I am explaining how I identified an opportunity to improve performance of LoopBack's REST API layer by 45%. Kudos to @NearForm for building @nodeclinic, the tool is very helpful and easy to use.

TIL: @deno_land is discussing how to switch the internals from TypeScript back to JavaScript. You can read more about their motivations here:

To be honest, I am often frustrated by TypeScript overhead too.

Awesome! Mocha landed support for running tests in parallel 🏎 Can't wait for the upcoming Mocha release. Thank you @b0neskull for the hard work you put into the pull request!

In a follow-up to my recent screen cast where I showed how to share LoopBack repository code, I wrote a blog post exploring even more options how to structure your repository-related code for reuse. Hint: ES6 class mixins FTW!

So if you want to work around list-style-position being broken for 20 years, do this: hide the standard list counters, use a custom counter, and set it to display in the ::before pseudo-element of your header. That provides the same effect.


ol {
counter-reset: index;

ol li {
counter-increment: index;
list-style-type: none;

ol li h3::before {
content: counter(index) '. ';
