A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Zoom Sucks

• Zoom abuses the installer flow on MacOS to bypass permissions dialogs (source)
• Zoom sends identifying device info to Facebook, even when users don't have a Facebook account (source) (fixed)
• A bug in Zoom sent identifying information (including email addresses and profile pictures) of thousands of users to strangers (source)
• Zoom claims that meetings are end-to-end encrypted in their white paper and marketing materials, but meetings are only encrypted in transit, and are available in plaintext to Zoom servers and employees. (source)
• zoomAutenticationTool can be used to escalat

Introduction

Hello! I'm doing some analysis of installed Ruby gems, specially those that require a compiler toolchain to be installed.

This analysis will help me determine an usage pattern and potentially work with gem authors to improve platform support for those gems.

Will be great if you can help me collect this information.

Just some notes and references for myself.

• In bash, you can access your C:\ drive via /mnt/c/
• ~ = C:\Users\MLM\AppData\Local\lxss\home\mlm and is different from your Windows user directory C:\Users\MLM

Persistent data storage on CoreOS-cluster

Storing the data on the host machine

Data directories are created in /home/coreos and mounted into the container using volume cli options of docker run. All data the container writes is stored on the host and as long as the host persists safe against container restarts / recreates.

• Pro
  • No effort, just create the directories and mount them into the container
• Contra
• Container is bound to host (unable to failover)
