compression

I was just looking at a code sample for compressing a string. I find that using the GZipStream class suffices. But I don't understand why we have to convert it to base 64 string as shown in the example. using System.IO.Compression; using System.Text; using System.IO; public static string Compress(string text) { byte[] buffer = Encoding.UTF8.GetBytes(text); MemoryStream ms = new MemoryStream(); using (GZipStream zip = new GZipStream(ms, CompressionMode.Compress, true)) { zip.Write(buffer, 0, buffer.Length); } ms.Position = 0; MemoryStream outStream = new MemoryStream(); byte[] compressed = new

You can set the HcDynamicCompressionLevel anywhere from 0-10. I've heard 10 is bad (high CPU usage), but what's the magic number that works the best? I've found that setting it to 8 gives a pretty good rate of compression without hammering the server too much. It will depend on your server load and specification. Settings of 5 to 9 for dynamic compression DO in fact hammer CPU load. Static compression occurs only once (until a file is re-cached) and you can set static compression high. This in-depth article recommends 4 for dynamic compression and 7 to 9 for static compression . The article

I have a C# application that communicates with a PHP-based SOAP web service for updates and licensing. I am now working on a feedback system for users to submit errors and tracelogs automatically through the software. Based on a previous question I posted, I felt that a web service would be the best way to do it (most likely to work properly with least configuration). My current thought is to use .NET built-in gzip compression to compress the text file, convert to base64, send to the web-service, and have the PHP script convert to binary and uncompress the data. Can PHP decompress data

I've written a program to perform run length encoding. In typical scenario if the text is AAAAAABBCDEEEEGGHJ run length encoding will make it A6B2C1D1E4G2H1J1 but it was adding extra 1 for each non repeating character. Since i'm compressing BMP files with it, i went with an idea of placing a marker "$" to signify the occurance of a repeating character, (assuming that image files have huge amount of repeating text). So it'd look like $A6$B2CD$E4$G2HJ For the current example it's length is the same, but there's a noticable difference for BMP files. Now my problem is in decoding. It so happens
