I’ve been thinking about making a little board game for me and my 2.5 year old boy to play. My thoughts so far are: A dice would mean that one of us could jump too far ahead to make it interesting. Plus Archie can’t count very well. So maybe writting ‘2’ on one side of Continue Reading
I wanted to show an image uploader (using Zend_Form_Element_File) but when the user was editing the image (replacing it) it showed the current image in the form. For some reason ZF devs won’t let you change the view helper for a Zend_Form_Element_File, so subclassing it and changing the view helper don’t work. There is a Continue Reading
Tags: Python, memory leak, leek, object, garbage collection, garbage collector, __del__, inspect, gc, DEBUG_LEAK I have a nasty memory leak in my Python script which I can’t find. For some random projects my script gobbles up 2gig of memory then quietly dies. Here is my first attempt at cobbling together a leak detector: import gc import inspect def dump_garbage(): Continue Reading
So, I was looking for a picture of a tree and found some nice pictures of fractal trees. That, I thought, would be interesting to code. Here are some of the results. This was coded in C#, each element ( a trunk/branch/twig ) is a fractal, a twig with a length < 3 aborts the Continue Reading
I had a problem with some URLs that we found on someones website. They looked like this: <a href=”http://example.com/../../../path/page.html”>, here is the same link: test. Notice that when you mouse over it, Firefox normalizes the URL so it looks correct. Using urlparse in Python: print urlparse.urljoin( ‘http://site.com/’, ‘/path/../path/.././path/./’ ) ‘http://site.com/path/../path/.././path/./’ How, poopy. So, we need to do better than that. The os module Continue Reading
BeautifulSoup is a python class that takes HTML and returns a tree of objects. You can then search that tree to find HTML tags (which is pretty mega easy.) Here is a little example that downloads the msn.com web page, parses it using BS and grabs all the LINK tags that are linking to a CSS file: from BeautifulSoup import BeautifulSoup import urllib2url = “http://www.msn.com” request = urllib2.Request(url) Continue Reading
I like Puzzle, the new music from Biffy Clyro. I really like it. But what the feck does Biffy Clyro mean? They are from Scotland, so I thought maybe it was where they came from. Nope. I did a lot of searches but could find nowt. Eventually I took Trays advice and just asked google, Continue Reading
Wow! Glass Shark at the Blue Bar on Saturday was freekin amazin. The band is made up of three dudes, one on lead guitar, on drummer and one bass. But for three guys they make a hell of a lot of noise . I like. I like a lot. They mostly played their own songs, but they also did Continue Reading
This post is about Zend Framework, sql error reporting. Problem: If your SQL has an error in it, Zend Framework throws a Zend_Db_Statement_Mysqli_Exception, the default exception message is pretty pants and does not show the whole SQL query (it only shows the first 10 characters or so!) Lets fix it so it shows the whole query. I found Continue Reading
