I went to the compression newsgroups, but all I saw was spam. So, I
thought I'd post his question here to get the best info I could from other
programmers.
Which compression algorithm offers the fastest compression of text data?
Which compression algorithm offers the best compression of text data?
I need to do in memory compression of text data before sending it over a
TCP connection. Zip is the old standby....but are there better...

Hi,
I am told that Oracle has this "data compression" feature that allows
you to store online data ina compressed format.
This is different from archived data - you compress only that data
which is infrequently accessed but is still available in the online
database.
I am interested in finding out an equivalent feature in DB2 UDB on LUW.
If there exists one, how should I go about implementing this?
If there is an alternative strategy to...

Is it best practice to set Unicode Compression to "No" for memo fields in a
table? What about text fields?
According to the VB help entry:
"Data in a Memo field is not compressed unless it requires 4,096 bytes or
less of storage space after compression. As a result, the contents of a Memo
field might be compressed in one record, but might not be compressed in
another record."

After writing the computing urban legend "The Helsinki Code",
I spent several nights thinking up how in the world Gustav
Larsson, the Finnish PDP-8 computer programmer, could have
managed to receive such a miraculous message from God.
Surely, for a 1-byte computer program such as "@" to compile
successfully (in RTPS FORTRAN), a miracle compression algorithm
would be necessary.
Then it dawned on me. Gustav had accidentally stumbled upon

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...

Dear All,
Now I met some performance problems in my application. Because according
to our business. The size of some web forms are larger than 1xxx MB. So it
takes a long time for user opening a web page. Surely we are modifying some
source code for performance improvment.
But now i'm thinking should we improve the application performance by
IIS Compression? I saw many mentions from Google/Yahoo. Some people said it
can be useful for...

Hello,
I want to add compression to a memory stream and save it in an Oracle
database. This is the code I have so far:
//save the Word document to a binary field,
MemoryStream dataStream = new MemoryStream();
doc.Save(dataStream, SaveFormat.Doc);
//now compress it
GZipStream compressedZipStream = new GZipStream(dataStream,

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, we have an app that scans documents into TIFF format and we
need to transfer them over the internet. If anyone knows of a SDK we
can use that can compress TIFFs on the fly or even if it can compress
them so they take up less space on the server, would be appreciated.
Actually any info on handling tiff files programatically would be
appreciated as I know very little about tiffs.
TIA

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:
