Whiteboard Picture Cleaner - Shell one-liner/script to clean up and beautify photos of whiteboards!

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Give network superpowers to docker

Unionize: network superpowers for your docker containers

Unionize lets you connect together docker containers in arbitrarily complex scenarios.

Note: I recommend to use https://github.com/jpetazzo/pipework instead.

  • pipework is a better name than unionize
  • it's hosted on a "real" github repo instead of a small gist :-)

Now if you want Unionize, it's still here. Just check those examples.

PrintCompilation on different versions of HotSpot VM

About PrintCompilation

This note tries to document the output of PrintCompilation flag in HotSpot VM. It was originally intended to be a reply to a blog post on PrintCompilation from Stephen Colebourne. It's kind of grown too big to fit as a reply, so I'm putting it here.

Written by: Kris Mok [email protected]

Most of the contents in this note are based on my reading of HotSpot source code from OpenJDK and experimenting with the VM flags; otheres come from HotSpot mailing lists and other reading materials listed in the "References" section.
