Introduction

Sometimes I want to make a screencapture of a websites behaviour.

In Chrome, I am quite happy doing this with the [Awesome Screenshot: Screen Video Recorder][1] extension.

Besides screenshots, the extension offers the ability to make a recording. (Limited to 30 seconds in the free version).

The recording can be uploaded to Youtube or Google Drive. It can also be downloaded as WebM file.

Installing Python 3.6 on Raspbian

As of January 2018, Raspbian does not yet include the latest Python release, Python 3.6. This means we will have to build it ourselves, and here is how to do it. There is also an ansible role attached that automates it all for you.

1. Install the required build-tools (some might already be installed on your system).

LOLCODE

LOLCODE is an esoteric programming language inspired by lolcat memes on the internet. The language was created in 2007 by Adam Lindsay, researcher at Lancaster University's Computing Department.

Here I have explained basics of LOLCODE with complete examples. However, you may have questions even after reading them because I have not included all details. For an exhaustive reference, read the official documentation.

Hacky syntax highlighting in git diff

Normally git diff would color additions green and deletions red. This is cool, but it would be even cooler if it adds syntax highlighting to those lines. This is a git pager that does so.

It parses the diff output and picks up the SHAs of files with additions and deletions. It uses [CodeRay][coderay] to highlight each file and then it extracts the lines that are shown in the diff. It then uses [term/ansicolor][color] to make a gradient from the CodeRay color and the diff color (red for deletion, green for addition) and uses it to replace the original.

I tried using rugged instead of shelling out to git show – it was faster overall, but it did incur a noticeable start up time.

Check out the image below for a demo.
