Book on JavaScript

If you see a JavaScript feature in this book that you don’t understand, you can look it up in my book “Exploring JavaScript” which is free to read online. Some of the “Further reading” sections at the ends of chapters refer to this book.

Books on TypeScript

The official “TypeScript Handbook” is a good reference for the language. It currently has a few holes that are filled by the release notes and GitHub pull requests (which handbook and release notes link to).
“TypeScript Deep Dive” by Basarat Ali Syed was not updated much after 2020 – e.g., it does not cover template string types. But this book is still a valuable resource.

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k

Einführung

Ich wurde jetzt schon öfters gebeten aufzuschreiben was mir alles geholfen hat, mit der Erholung vom Postcovid anzufangen und mich so zu verbessern. Anstatt das immer wieder aufzuschreiben, mache ich jetzt lieber diesen Text. Hoffentlich ist er für euch hilfreich. Ganz wichtig vorneweg: Nur weil etwas für mich funktioniert hat, heißt es nicht, dass es auch für alle anderen die unter Postcovid oder gar ME/CFS leiden funktioniert.

Kurz zu mir und meinem Krankheitsverlauf: Ich bin gerade 44 Jahre alt und männlich. Im Februar 23 hatte ich mir leider Covid eingefangen, das unauffällig verlief.

Ich fahre gerne viel Fahrrad und hatte 3 Wochen Pause gemacht, bevor ich wieder mit dem Training anfing. Meine Fitness stellte sich nur langsam teilweise wieder her. Ich machte Fortschritte und versuchte mich trotzdem im Mai an meinem ersten Bikepacking-Rennen. Nach einer sehr unbefriedigenden Leistung am ersten Tag litt ich unter meinem ersten großen Crash. Mei

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

`package.json`

This gist is a simple no-brainer description of the 3 ways (actually 2.5) the Web handle events.

`<tag onclick />`

The declarative inline HTML event listener is mostly an indirection of DOM Level 0 events, meaning this simply uses the equivalent of tag.onclick = listener behind the scene.

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

Foundational Concepts

Pre-Transformer Models

This is the gist of how to setup a NixOS server on a Hetzner Cloud instance with an admin user, ssh access and configuration management via git.

Create a Hetzner Cloud instance and click to enter it.
Stop the instance (top right corner icon).
Go to ISO Images.
Search for "nixos" and click mount.
Start the instance again (top right corner icon).
Open the console (top right corner icon).
Get the IP address by executing ip --brief --color address. The address can also be optained from the Hetzner Cloud web interface.

	window.lColors = ['white', 'black', 'purple', 'darkgray', '#009'];
	window.lWidths = [5, 10, 20];
	window.jCols = parseInt(document.getElementById('info-creator').innerText.match(/(\d+)×/)[1]);
	window.jC = 0;
	CanvasRenderingContext2D.prototype.putImageData = function(imageData, dx, dy){
	const col = window.jC % window.jCols;
	const row = Math.floor(window.jC / window.jCols);
	this.fillStyle = window.jColors[col % window.jColors.length];
	this.fillRect(-1000,-1000,2000,2000);
