Patent Office tries “Stack Overflow for patents” to find prior art | Ars Technica

2012 Sep 20, 2:27

Welcome news. Glad to hear they’re looking for improvements.

… the USPTO has also worked with Stack Exchange, … to create a new site called Ask Patents. … Examiners or others looking for prior art can post questions about a specific application, and members of the general public can respond with evidence that an applicant was not the first to invent the subject matter of the application.

HTTP Compression Documentation Reference

2012 Jun 13, 3:08
There's a lot of name reuse in HTTP compression so I've made the following to help myself keep it straight.
HTTP Content Coding Token gzip deflate compress
An encoding format produced by the file compression program "gzip" (GNU zip) The "zlib" format as described in RFC 1950. The encoding format produced by the common UNIX file compression program "compress".
Data Format GZIP file format ZLIB Compressed Data Format The compress program's file format
Compression Method Deflate compression method LZW
Deflate consists of LZ77 and Huffman coding

Compress doesn't seem to be supported by popular current browsers, possibly due to its past with patents.

Deflate isn't done correctly all the time. Some servers would send the deflate data format instead of the zlib data format and at least some versions of Internet Explorer expect deflate data format instead of zlib data format.
