Script to grab one of the 10 more recent images from Unsplash, and tint and blur it for use as an iTerm background using Solarized Dark
#!/bin/bash
# NOTE: requires ImageMagick
# NOTE: will tint to the Solarized Dark default background scheme, as the iTerm background blend option didn't lower the contrast enough for me
# NOTE: Optimised for a 1280x800 point screen (my 13" Retina MBP)

Created September 3, 2014 09:36
A reasonably naïve Blob implementation in C++, complete with Array and Hash packed data types.
#include "Blob.h"
namespace sol {
unsigned Object::used() const {
BlobType type = (BlobType)_blob.getByte(0);
switch (type) {
case BL_INT:
return Integer(_blob).used();
case BL_ARRAY:
return Array::wrap(_blob).used();

Created August 5, 2014 12:08
Jenkins script to force push Jekyll to Github Pages each day, for scheduled blog posts. Run this as a Jenkins Job on your blog git repository, and set to 'build periodically'. My cron job reads 'H 7 * * *'.

Force updated by Jenkins build $BUILD_ID"
git push -f origin HEAD:master

Use this little script to serve an Atom feed about your git repo. I use it to show a rolling ticker on my Twitch.TV live dev streaming channel. See it in action here: http://twitch.tv/chrismdp_

Simple http server in ruby, that ensures there's no browser caching. For serving static files in development. I copy this into my ~/bin directory.

require 'webrick'
class NonCachingFileHandler < WEBrick::HTTPServlet::FileHandler

res['ETag'] = nil
res['Last-Modified'] = Time.now + 100**4
res['Cache-Control'] = 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0'
res['Pragma'] = 'no-cache'
res['Expires'] = Time.now - 100**4

Shell script to grab latest tasks from Wunderlist 2. The path for the DB file is the App Store version. Note that as well as passing the list you want (or "" for all tasks) you can pass a relative time as a second argument: eg "+7d" which will limit the view to only tasks due within that time. ("+7d" limits tasks shown to those due within the ne…
