    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (116 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

A monthly roundup of all news and happenings reported at The Data Compression News Blog. More information about this newsletter at http://www.c10n.info/newsletter/

I have further refined the recently added a section which keeps track of all industry news and press releases using Google’s excellent News service. Check it out at http://www.c10n.info/newsbot or on the homepage.

Another section added is the “Benchmark updates” section on homepage, it will make it easy for you to track any updates made to the popular compression benchmarks. Right now it only has updates from maximumcompression.com, more benchmarks will be added soon.

Among other things which I would love to see at www.c10n.info is a section featuring the latest research papers published on topics of our interest. And one featuring the latest data compression patents granted or filed. I have explored further on how the patents section can be built, you will be seeing it soon.

And as usual, any tips or advice you offer will really help a lot in making c10n.info a better site for all of us :-)
