Using PNG Predictors to Enhance GZIP/PKZIP/FLATE Compression

Sat, 03 May 2008 02:08:09 GMT

While implementing Binary Cross Reference Streams we were surprised to see that they could be encoded with PNG Predictors. This was surprising because binary cross reference streams aren't images, they are byte tables. The first byte can only contain the numbers 0, 1 and 2 and are often the same, the middle two bytes are often the same and the last byte is generally increasing by one each time. Knowing this about the data you can develop a lossless algorithm which normalizes the data and so makes PKZIP/GZIP/FLATE compression work much better.

Convert Relative Paths to Absolute Using Regular Expressions

Wed, 12 Sep 2007 10:48:12 GMT

I ran into a situation where I needed to screen scrape some content from a site and display it on my own site. This works really well except for dependent files like javascripts, SWFs and images that had src attributes with relative paths. So I figured it wouldn't be that hard to create a helper method to find and replace them using Regular Expressions.
