Getting a Shell in the Docker Desktop Mac VM

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

Story: Writing Scripts with Go

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

A primer on x86 assembly with GNU assembler

When it comes to assembly language, it isn't as hard as many people think. Fundamentally, you write short, human-readable commands for the processor to execute (your assembly code) and then use a tool (the actual assembler) to translate your code into machine-readable binary instructions. Unlike high-level languages, assembly language is very simple and doesn't have that many features. The difficulty is to deal with memory and build more complex flows (e.g. loops or I/O) from the simple primitives that the assembly language gives you.

Registers and instructions

CPUs usually have small, very fast storage available for the data that is used in its instructions. This kind of storage is much smaller but also much faster than the RAM and is called registers. An x86 processor has a bunch of them to store generic data, manage the stack, keep track of the current instruction and other administrative inform

Programmatically send push notifications to telegram from python
  1. Create a new Telegram bot:
    1. start a chat with BotFather;
    2. type /newbot, select a name (to be shown in chats) and handle for your bot;
    3. note the bot token to access HTTP API - a long string with a colon in the middle (later referred to as <token>);
    4. optionally /setdescription and /setuserpic.
  2. Add the bot to the chat/channel and note its id:
    1. add the bot to a new or existing chat or group - this is where your bot will send notifications to;
    2. go to https://api.telegram.org/bot<token>/getUpdates (replace <token> with your token);
    3. within the chat part, find and note the id field - a positive or negative number (later referred to as <chat_id>).
  3. Programmatically send notifications:

Use a Git commit message template to write better commit messages

Using Git Commit Message Templates to Write Better Commit Messages

The always enthusiastic and knowledgeable mr. @jasaltvik shared with our team an article on writing (good) Git commit messages: How to Write a Git Commit Message. This excellent article explains why good Git commit messages are important, and explains what constitutes a good commit message. I wholeheartedly agree with what @cbeams writes in his article. (Have you read it yet? If not, go read it now. I'll wait.) It's sensible stuff. So I decided to start following the

#define _GNU_SOURCE
#include <errno.h>
#include <sched.h>
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
#include <sys/mount.h>
#include <sys/stat.h>
#include <sys/syscall.h>
#include <sys/types.h>
