bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting.

HTTP compression is a capability that can be built into web servers and web clients to improve transfer speed and bandwidth utilization. [1]HTTP data is compressed before it is sent from the server: compliant browsers will announce what methods are supported to the server before downloading the correct format; browsers that do not support compliant compression method will download uncompressed ...
Because of its significantly slower compression speed, Zopfli is not suited for on-the-fly compression. It is typically used for one-time compression of static content. [7] [8] This is typically true for web content that is served with Deflate-based HTTP compression or web content in a Deflate-based file format such as PNG or WOFF font files. [9]
A string s is compressed to the shortest byte string representing a base-256 big-endian number x in the range [0, 1] such that P(r < s) ≤ x < P(r ≤ s), where P(r < s) is the probability that a random string r with the same length as s will be lexicographically less than s.
Another disadvantage is that some utilities can no longer identify run-time library dependencies, as only the statically linked extractor stub is visible. Also, some older virus scanners simply report all compressed executables as viruses because the decompressor stubs share some characteristics with those. Most modern virus scanners can unpack ...
Facebook is rolling out a new tool that lets it track the links users click on. The new system, called “link history”, is a catalogue of websites that people have visited within Facebook.
The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor. [6] As of its 2014 release, the site was still in early stages, with much work remaining to polish the code for Tor access.
