Uber Reduces Logging Costs by 169x Using Compressed Log Processor (CLP)
Uber recently published how it dramatically reduced its logging costs using Compressed Log Processor (CLP). CLP is a tool capable of losslessly compressing text logs and searching them without decompression. It achieved a 169x compression ratio on Uber's log data, saving storage, memory, and disk/network bandwidth.

Portable Compression Libraries for .NET 4.5, Windows Store and Windows Phone
Microsoft has released a beta of a new portable library called Bcl.Compression that adds support for zip archives and compress streams (i.e. deflate and gzip) for the Portable Http Client. Unfortunately it requires a native library so Silverlight and Windows Phone 7.x developers are out of luck.

Support for Zip Files Still Lacking In .NET 3.0
The ability to use file compression like the venerable ZIP format is very important to many developers. For those developers using.NET, that means dropping to command shell or using a third-party component. With .NET 3.0, there is built-in support for ZIP files, though the implementation is somewhat questionable.
