Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

Default

Powerlevel10k

The program below can take one or more plain text files as input. It works with python2 and python3.

Let's say we have two files that may contain email addresses:

file_a.txt

foo bar
ok [email protected] sup
 [email protected],wyd
hello world!

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

	#!/bin/bash

	set -e

	# Utility functions

	## For ease of iterative experimentation
	doo () {
	$@
	# echo $@

	# I use ZSH, here is what I added to my .zshrc file (config file)
	# at ~/.zshrc

	# Have the adb accessible, by including it in the PATH
	export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:path/to/android_sdk/platform-tools/"

	# Setup your Android SDK path in ANDROID_HOME variable
	export ANDROID_HOME=~/sdks/android_sdk

	# Setup aapt tool so it accessible using a single command

	#!/usr/bin/env bash
	set -e

	main() {
	previous_file="$1"
	file_to_edit=`select_file $previous_file`

	if [ -n "$file_to_edit" ] ; then
	"$EDITOR" "$file_to_edit"
	main "$file_to_edit"

	If you want to clone an svn repository with git-svn but don't want it to push all the existing branches, here's what you should do.

	* Clone with git-svn using the -T parameter to define your trunk path inside the svnrepo, at the same time instructing it to clone only the trunk:

	git svn clone -T trunk http://example.com/PROJECT

	* If instead of cloning trunk you just want to clone a certain branch, do the same thing but change the path given to -T:

	git svn clone -T branches/somefeature http://example.com/PROJECT
