Errr... I could swear when I was at work (yesterday) there had been links to the new version "0.1" Now they are gone And even stranger: no entry "Last edited" inside the posting of Francesco...
Am I going mad or have I taken the wrong medicine...?!
Thanks again to LovePimple!

Best regards!

i have done some tests with your new bzp archiver
it is fast and have a good compression ratio

but will it be possible to implement the algorithms
from your rings 1.3 or later

within the bzp archiver ?

because in several cases

rings is faster by better compression ratio

[Nania Francesco]

I am at work to always improve my programs! BZP founds him on an algorithm simple lzp but that exploits at the most the context of compression!

[Sportman]

I added BZP 0.2 to http://www.metacompressor.com/uploads.aspx

I also added a new test file14 with 250 HTML pages and 250 text headers, because this file is only 5,629,573 bytes I added 3 extra digits (milliseconds) to the compression and decompression time in case time is < 60 seconds.

Archivers can still be uploaded for live testing:

Thanks Sportman ! Good job!

[LovePimple]

Thanks Sportman!

[Sportman]

I added a login option what give access to a detailed list of all archivers added with that email address.

http://www.metacompressor.com/newuser.aspx
http://www.metacompressor.com/login.aspx

It's only a start I shall add more features.

@Sportman:
Thanks. I've just created my profile. I advice create a new thread about metacompressor.com like: "MetaCompressor.com Benchmarks". Else, we cannot easily track your news. Best Regards.

[Nania Francesco]

Thanks Sportman!

I finally got around to testing bzp.
http://cs.fit.edu/~mmahoney/compression/text.html#2839
It is on the Pareto frontier for compression speed but I have not updated the graphs yet.

Also I noticed in testing that if I compress a file in another folder like below then the path name is stored wrong. I compress \res\enwik8 and the name is stored as s\enwik8 with the first 3 characters cut off. Then when I decompress to . it creates a new subdirectory .s and saves .s\enwik8

C:\tmp>timer bzp c \res\enwik8 x8

There was no problem for the actual test where I compressed enwik8/9 in the current directory (to get proper file size).

Also, this is actually bzp 0.2 (according to readme.txt) although program says 0.1.

Thanks Matt for all !
