I'm writing a little analysis page which will help me hunt down bugs in an application. In essence it allows to visually compare actual data and log entries, plus perform a bit of analysis on the data. Since this is for debugging only and since I will be deploying this on the live site I want it to have as little server load as possible...
I've downloaded ICSharpCode.SharpZipLib and DotNetZip. I'm zipping over 100 files at a time varying a meg to 4 megs. When I use ICSharpCode I get a 'ContextSwitchDeadlock' error. DotNetZip fails on the finalizing of the file every time. Also, I'm working on sharepoint folders (mapped to my local drive) private bool zipall() //ICShar...

I'm looking for a general compression library that supports random access during decompression. I want to compress wikipedia into a single compressed format and at the same time I want to decompress/extract individual articles from it. Of course, I can compress each articles individually, but this won't give much compression ratio. I've...
I have an XML file format .zfo that is compressed using zip algorithm. I need to remove this compression from the file, so that it is in usable XML form. How can I remove this compression, or decompress this XML file? Its not like you might imagine i.e: .zip file containing an xml file. Instead the byte[] thats written to the file is ...
(Note: I have solved this problem, but it took long enough that I'm posting question/answer here.) The Xcode build process "optimizes" my PNGs when building. This isn't usually a problem, but iTunesArtwork being processed in this way causes corrupts it so that iTunes not to be able to show it. How can I prevent this? ...

After changing .zip file mime type on IIS 6 metabase to (application/x-zip), I can see that .zip downloads with a new content type when I download it from static folder (/zip) But I use ISAPI extention to download .zip the mime type (?downloadname=filename thus dynamic content) changes it to (application/x-zip-compressed). Verified it wi...
I have started to look into Hadoop. If my understanding is right i could process a very big file and it would get split over different nodes, however if the file is compressed then the file could not be split and wold need to be processed by a single node (effectively destroying the advantage of running a mapreduce ver a cluster of paral...
Are there any OSS compression libraries (gzip) available for J2ME? ...
Noticing that byte-pair encoding (BPE) is sorely lacking from the large text compression benchmark, I very quickly made a trivial literal implementation of it. The compression ratio - considering that there is no further processing, e.g. no Huffman or arithmetic encoding - is surprisingly good. The runtime of my trivial implementation ...
I have found the DIY Map.. an excellent map tool if you are ever looking for one. Aside from how fantastic it is... the associated XML file can get fairly large (it contains map setting, country names etc). I was wondering if it were possible to compress it and have javascript uncompress it on the users side.... There is a lot of repeti...
On PHP.net I am looking at the Memcache::set function and it has this optional flag to use compression... Use MEMCACHE_COMPRESSED to store the item compressed (uses zlib). $memcache_obj->set('var_key', 'some really big variable', MEMCACHE_COMPRESSED, 50); I am curious...
Say there's an array of 1024 bits that are all zeros: example: [0,0,0,0,0,0,0,...] Then I overwrite 20 zeros with ones at completely random positions: example: [0,1,0,0,0,0,0,...] What is the theoretical minimum number of bits needed to encode the location of these 20 randomly placed bits, assuming that I had a perfect encoder? I k...
How would I turn a directory into a zip file with PHP? Thanks. ...

I'm having difficulty making IIS 7 correctly compress a Json result from ASP.NET MVC. I've enabled static and dynamic compression in IIS. I can verify with Fiddler that normal text/html and similar records are compressed. Viewing the request, the accept-encoding gzip header is present. The response has the mimetype "application/json", bu...
