“You need to learn to delegate” … That’s not always easy due to a variety of situations out of one’s control : @hhariri on Thread Reader App

Posted by jpluimers on 2026/07/24

A year ago, Hadi Hariri wrote this very important Tweet which I preserved through [Wayback/Archive] Thread Reader App because the Space Karen hates the Wayback Machine so much that it still can’t archive tweets ¹:

[Wayback/Archive] Thread by @hhariri on Thread Reader App

“You need to learn to delegate”

Learning to delegate is not that hard. Delegating, and doing it successfully on the other hand, requires having the right people to delegate to.

That’s not always easy due to a variety of situations out of one’s control.

Luckily, Archive.is can still archive Tweets, so here is the original one: [WaybackSave/Archive] Hadi Hariri on X: “”You need to learn to delegate” Learning to delegate is not that hard. Delegating, and doing it successfully on the other hand, requires having the right people to delegate to. That’s not always easy due to a variety of situations out of one’s control.”

 

Anyway, I responded with my story, which I archived too, but this time because Twitter does not allow viewing threads as an anonymous user since 2021: [Wayback/Archive] Twitter won’t show complete threads now without an account. :( Twitter accounts … | Hacker News.

My story [Wayback/Archive] Thread by @jpluimers on Thread Reader App

@hhariri Especially when explaining what and how to a delegatee is taking more time/energy/effort than doing it yourself.

Still training the new internal care of my brother. Costs less energy than last year, but back then the old “ambulant” care took 2 hours and then “it was OK”.

@hhariri Weekly I try to figure out what happened then hours re-explaining “treat him like he is: mentally a 3 year old with autism in a full grown body that seems to speak Dutch very well, but does not really understand what he says. So what he says is different from what he wants/needs”

@hhariri And for “normal work”, the life long job is to keep explaining that doing things right the first time saves a lot of effort.

@hhariri And yes, there is hindsight when at the time you did things, you didn’t know there was or would become a better way, or that the current situation changed.

Those are valid reasons for redoing things later, but not valid reasons for not even trying to do it right the first time.

In case you have a Twitter account, you can find the thread start at [WaybackSave/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@hhariri Especially when explaining what and how to a delegatee is taking more time/energy/effort than doing it yourself.

¹ sometimes it archives something of the tweet, in this case the [Wayback/Archive] Tweet JSON which you normally would get through the Twitter CDN like [Wayback/Archive] Tweet JSON (I wrote about creating a JavaScript Bookmarklet for this method in Probably many more like these are needed to download Twitter videos: [extractor/twitter] Fix unauthenticated extraction by bashonly · Pull Request #7476 · yt-dlp/yt-dlp).

bluesky-social/social-app: The Bluesky Social application for Web, iOS, and Android

Posted by jpluimers on 2026/07/21

Took me a while to notice this is open source: [Wayback/Archive] bluesky-social/social-app: The Bluesky Social application for Web, iOS, and Android

Via [Wayback/Archive] Gergely Orosz on Twitter: “Wow. The other Blue site open sourced their app (The protocol is already open sourced) Unlike Twitter’s recommendation algorithm that is a fork (and not the real thing), both these are the prod thing. This developing in the open is new, and encouraging! “

GitHub – breakzplatform/downloader.notx.blue

Posted by jpluimers on 2026/07/14

Interesting, as this seems to handle all actions client-side: [Wayback/Archive] GitHub – breakzplatform/downloader.notx.blue

Hosting is at two sites:

The code is a tiny HTML wrapper around about 1000 lines of JavaScript (plus a few hundred lines of minified [Wayback/Archive] GitHub – ffmpegwasm/ffmpeg.wasm: FFmpeg for browser, powered by WebAssembly JavaScript code). Impressive!

Know your TypeScript/JavaScript operators… or why having little ceremony sometimes makes programmers life harder

Posted by jpluimers on 2026/05/12

const a = undefined; const result1 = a ?? 0 + 10; const b = 100; const result2 = b ?? 0 + 10;Take this cool example I extended from [Wayback/Archive] Thomas 🅰️🇨🇵 on Twitter: “#Typescript quizz What will be the value of result1 and result2 ?” which lacked alt-badge, so I [Wayback/Archive] responded with the image on the right that has alt-text.

Based on that, I added a bit of logging:

const a = undefined;
const result1 = a ?? 0 + 10;

const b = 100;
const result2 = b ?? 0 + 10;

console.log(result1);
console.log(result2);

Two questions:

  1. What is the output of both log lines?

AbortController is your friend

Posted by jpluimers on 2026/05/06

Cool post [Wayback/Archive] AbortController is your friend starting with

One of my favorite new features of JS is the humble AbortController, and its AbortSignal. It enables some new development patterns, which I’ll cover below, but first: the canonical demo.

It’s to use AbortController to provide a fetch() you can abort early:

It then continues with a series of nice use cases.

Via [Wayback/Archive] Roderick Gadellaa on Twitter: “Late to the party here (was published in June last yr) but great read if you (like me) missed it”.

Some Twitter internals after I found GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives

Posted by jpluimers on 2026/04/30

Found this while trying to find the source from which I constructed this Bookmarklet which from a Tweet URL returns the JSON metadata which has all the links to media (like images and videos) as it failed for broadcasts:

javascript:{ tweetID = document.location.href.split('/').filter(e => e).slice(-1); url = new URL(`https://cdn.syndication.twimg.com/tweet-result?id=${tweetID}&token=!`); open(url); }

I could not find that back, but did find [Wayback/Archive] GitHub – offish/twitter-broadcast-downloader: Download Twitter broadcasts/lives via these query steps:

Some pages that have lists of Amazon toplevel domains

Posted by jpluimers on 2026/04/16

Amazon has activities spread across many different countries and regions, heck they even own their own toplevel domain .amazon.

Yesterday in Online tools to test JSONPath Queries (plus a small list of Amazon top level domains) I wrote about the JSON parsing I did for Download your Kindle books soon, because Amazon will block them after February 25, 2025 .

The source of that list is [Wayback/Archive] Amazon operating domains by country. · GitHub [Wayback/Archive] in the file amazon-domains.json.

In the meantime, I finally managed to go through a list of old open browser tabs having more of such lists. Here they are:
