bzip2 is a free and open source implementation of the Burrows–Wheeler algorithm. It is developed and maintained by Julian Seward. Seward made the first public release of bzip2, version 0.15, in July 1996. The compressor's stability and popularity grew over the next several years, and Seward released version 1.0 in late 2000.
Like gzip, it is only a compressor for single files and not a full archiver.
bzip2 compresses most files more effectively than the older LZW (.Z) and Deflate (.zip and .gz) compression algorithms, but is considerably slower. LZMA is generally more space-efficient than bzip2 at the expense of slower compression speed, while having much faster decompression.
bzip2 compresses data in blocks of size between 100 and 900 kB and uses the Burrows–Wheeler transform to convert frequently-recurring character sequences into strings of identical letters. It then applies move-to-front transform and Huffman coding. bzip2's ancestor bzip used arithmetic coding instead of Huffman. The change was made because of a software patent restriction.
Watawat Lyrics
Peacepipe
Ako ang tunog ng ating kulay
Sumasagisag sa watawat ng ating bayan
Ako'y may sariling paninindigan
Kumakalinga sa agos ng kalikasan
Chorus:
Laya laya kalayaan..
Sumasayaw s tunog ng kapayapaan2x
Ako ang himing ng lupang hinirang
Bayan ng magigiting ang sinilangan
Pag-ibig sa bayan at sa puso at diwa
Itaguyod ang watawat ng inang bayan
Repeat Chorus
