Slashdot Quotes database

https://dhedegaard.dk/python/2012/09/29/slashdot-quotes-database.html

Sep 29, 2012 Dennis Hedegaard. Website at the bottom there is a quote that changes from time to time (according to my tests, every hour). I've collected a database of the quotes and is currently at 2381 entries. I've implemented a nice graphical interface to searching the database in Django, the database runs on PostgreSQL. The site can be found here: http:/ sd.dhedegaard.dk/. Rambling thoughts of a software developer.

Making jpg transparent with PIL. Feb 18, 2013 Dennis Hedegaard. A fun experiment, how hard is it to convert a jpg (or anyting else) to a transparent png using PIL (Python Imaging Library)? Not very hard it seems, the source can be found here:. Https:/ bitbucket.org/dennishedegaard/transparentpng/src/194d8e5f1dad1491259ad697e9085f3726445b9b/transparentpng.py? In later commits a webinterface for GAE can be found here: http:/ transparentpng.appspot.com/. Rambling thoughts of a software developer.

Long-polling chat application in Django

https://dhedegaard.dk/python/javascript/2013/02/15/long-polling-chat-application-in-django.html

Long-polling chat application in Django. Feb 15, 2013 Dennis Hedegaard. Back when I was a student I messed around with websockets (back then it was grizzly on glassfish). Now adays most of my development is done in python. The nice thing about websockets is that it's like a TCP-socket where both parties can send data, websockets are like this, but over HTTP. This allows the server to send data to the client without the client being the active party. The basic "usecase" for long-polling is described below.

Snake game in HTML5. Dec 4, 2011 Dennis Hedegaard. I spend my sunday implementing a snake game in javascript with the drawing done in a HTML5 canvas element. I've tested it in firefox 3.6 on lucid as well as chrome 15 and firefox 8.0.1 on mint isadora. Any information whether it works on Internet Explorer is appreciated since I do not have to opportunity to test it myself :). Here's the link: http:/ p.dhedegaard.dk/snake/. Feel free to look in the source and find all my bugs :).

Perl: Linuxstat

https://dhedegaard.dk/perl/2010/10/05/perl-linuxstat.html

Oct 5, 2010 Dennis Hedegaard. A week ago I started working on a small project, with the goal of showing CPU, memory usage and swap usage in a web interface. I chose perl for the job, utilizing rrdtool, cronjobs and mod perl for cgi. Swap seemed bothersome, so I used /usr/bin/free and parse the input, the problem with parsing swap from /proc/swaps is if there are more than 1 mounted swaps. Git: http:/ git.neo2k.dk/? Demo: http:/ neo2k.dk/linuxstat/index.cgi. Comments and bugs are welcome.

Finding duplicate files with Go

https://dhedegaard.dk/languages/go/2014/08/13/finding-duplicate-files-with-go.html

Finding duplicate files with Go. Aug 13, 2014 Dennis Hedegaard. For some time now, I've been messing around with the Go programming language. I like the idea of a systems language with a modern take on the standard library (like build in support for JSON, HTTP calls and built in vectors called slices), concurrency, easy use of 3rd party dependencies and fast, clean code. It goes something like this:. For all hashes with multiple filenames, print them as duplicates and let the user choose what to do.
