docker run: determining if --init is needed

Normally, if a program doesn't set a SIGTERM handler, it needs --init:

Dockerfile:

FROM alpine:3.20
COPY a.c .
RUN apk add build-base \

Using TransformStream in place of traditional queue implementations is an interesting approach that leverages the stream API's natural queuing and backpressure features. Below is a breakdown of how you might implement each queue type using TransformStream, adhering to the constraint of using no more than 2 TransformStreams per queue, and addressing any limitations that arise.

1. Simple Queue (FIFO Queue)

• Implementation:
  • TransformStream 1: This stream simply passes data from the writable side to the readable side in FIFO order.
  • TransformStream 2: Not necessary in this case, as one TransformStream is sufficient to maintain the FIFO order.

const fifoQueue = new TransformStream(undefined, undefined, { highWaterMark: Infinity });

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

How to set up a Telegram Proxy (MTProxy)

This tutorial will teach you how to set up a Telegram MTProxy on an Ubuntu 22.04 sever using AWS Lightsail, although you can use any other Linux distribution and cloud provider.

Using a Telegram proxy is a safe, easy and effective way of overcoming Telegram bans. It's useful, for example, to keep using Telegram under tyrannical regimes, or to circumvent judges' decisions to block Telegram.

Telegram proxies are a built-in feature in all Telegram apps (both mobile and desktop). It allows Telegram users to connect to a proxy in just one or two clicks / taps.

Telegram proxies are safe: Telegram sends messages using their own MTProto secure protocol, and the proxy can only see encrypted traffic – there's no way for a proxy to decrypt the traffic and read the messages. The proxy does not even know which Telegram users are using the proxy, all the proxy sees is just a list of IPs.

// Usage:
//   node --import=./typescript-hook.js --watch ./dist/index.js
//
// Make changes to your TypeScript code, have it automatically
// recompiled, and see it reloaded in Node.js.
//
// This file is intended to be used as a Node.js preload module.
// The TypeScript compiler (tsc) will be run in watch mode.
// This is useful while running Node.js itself runs in watch mode.

tsc performance consuming .ts vs .d.ts files in npm packages

What if TypeScript libraries published just .ts sources to npm instead of .js and .d.ts files? This might already be tempting for Bun-only libraries, but how will that impact users? This is easy to answer by experimenting on existing libraries that ship .js, .d.ts, and .ts files.

RxJS ships .js and .d.ts files, but also .ts files for debugability purposes. By tweaking its package.json "exports", we can compare tsc performance on this file with imports resolving to .d.ts files vs .ts source files:

import {} from "rxjs";
