Nix Script to simulate FHS environment with python3 & pip & venv
#!/usr/bin/env -S bash -c 'nix-shell --pure $0 -A env'
# Usage:
# 1. run directly to enter bash (inside venv): `./venv-py37.nix`
# 2. build a standalone executable: `nix bundle -f ./venv-py37.nix` #this not works yet since it cause nested `unshare -U` call
# 3. run bash with extra arguments: `nix run -f ./venv-py37.nix '' -- -c 'python --version'`
# More:
# 1. commit id of nixpkgs can be found here: https://lazamar.co.uk/nix-versions/?channel=nixpkgs-unstable&package=python3

Terminal Spec: Synchronized Output

This page has moved!

Please see here: contour-terminal/vt-extensions

Synchronized Output

Synchronized output is merely implementing the feature as inspired by iTerm2 synchronized output, except that it's not using the rare DCS but rather the well known SM ? and RM ?. iTerm2 has now also adopted to use the new syntax instead of using DCS.

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,
