Supercomputer and encryption and compression @ rate of 96%
Take a document then or a 3D matrix document change it two random or
binary code or just a program for 0's and 1's and fold it over and over
like a piece of paper then having the 1 and 0 add each other or the
0,1's canceling each other out 1+0=0 and 0+1=1 1+1=1 0+0=0 if you gave
the folds addresses like on a spread sheet there would be no math.
First A 1-24 would fold to k 1-24...

I am looking for an algorithm I can use in C# that compresses small XML
documents. Is there a chance of losing some literal data on
decompression (as some claim)? How fast is the
compression/decompression process?
Thanks.

I'm writing a program in python that creates tar files of a certain
maximum size (to fit onto CD/DVD). One of the problems I'm running
into is that when using compression, it's pretty much impossible to
determine if a file, once added to an archive, will cause the archive
size to exceed the maximum size.
I believe that to do this properly, you need to copy the state of tar
file (basically the current file offset as well as the state of...

I not really sure this is the right newsgroup so please excuse me if it
is not.
I am trying to create a simple compression algorithm using the LZW
system and I can find a lot of information on the general description of
it, but how exactly does the dictionary that is used work. Is it just
stored in an array or do you need to write it to a file so that it can
be used the next time you need to decompress a file. I would think it
would...

The compression part of this code works fine for me, but the decompression
part of this code does not. The output file from that is the same as the
compressed file.
What is wrong with my code?
Thanks,
Jon
'compression starts here
Dim src As FileStream = File.OpenRead(Fn)
Dim dst As FileStream = File.Create(Ofn)
Dim cmp As New DeflateStream(dst, CompressionMode.Compress)

I compressed a file with GZipStream class and is larger than the original
file.... how can this be?, the original file is 737 KB and the "compressed"
file is 1.1 MB. Did i miss something or is normal with that compression class?

Hello,
I have a script that generates XML files which are sent to a client app
on request via "new SimpleXMLElement( $sUrl, 0, true )". Both client and
server run PHP 5.2 and the XML file can get as large as about 150 KB.
(The client then generates an HTML page using the data in the XML file
and sends it to the browser. So there are 3 parties involved: User
requests HTML page - server requests XML data from other server - other

I just added save-to-PNG to our software and noticed that WPF generates
enormous PNG files. Re-encoding them under Linux makes them 20x smaller.
Is it possible to enable compression under .NET or is PNG not properly
supported?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
