I'm a developer living/working in Malmö, Sweden. I mostly write in Javascript, some Java and increasingly more Go and Python, and bash when it's needed.

My main interests technologically include web technologies, automation and image processing.

You can find my PGP key on pgp.mit.edu. I try and remember to PGP sign when I tag. You can use git verify-tag to verify the tag! My key ID is 83868A38.

Go program interaction

Example of how to use stdout and stdin from other programs in golang

Requires go

Run

go run parentprocess.go

Go pointers

This gist demonstrates the use of pointers in go (and other similar languages)

Use &x to get the address of x

Use *x to get a value from an address x

When should I use a pointer?

Remove any libgit2 packages you already have, otherwise these will be included first and they do not necessarily have everything needed that you need for pygit2/git2go.

sudo apt-get purge libgit2-0 libgit2-dev

From http://www.pygit2.org/install.html

wget https://github.com/libgit2/libgit2/archive/v0.23.4.tar.gz
tar xzf v0.23.4.tar.gz
cd libgit2-0.23.4/

cmake .

	Tool to find files with the same name within a directory.
	Developed to help with detection of unused files that weren't being detected as unused by require.js as they had the same names as other files that were being imported.

	usage:
	python find-duplicate-filenames.py [path]
	options:
	path: path on which to look. Defaults to the current working directory.

	#!/bin/bash

	RED='\033[0;31m'
	NC='\033[0m' # No Color

	# pre-commit hook to check new files are always added to the master branch and deletions are always made in feature branches.
	# useful when master should contain all the files ever added (eg. in a media project), and the feature branches can offer 'views' of parts of them


	branch_name=$(git rev-parse --abbrev-ref HEAD)

	Some Go/Cgo code

	go run cgo.go
