Fog computing Updated +Created
Our definition of fog computing: a system that uses the computational resources of individuals who volunteer their own devices, in which you give each of the volunteers part of a computational problem that you want to solve.
Folding@home and SETI@home are perfect example of that definition.

Metagenomics Updated +Created
Experiments that involve sequencing bulk DNA found in a sample to determine what species are present, as opposed to sequencing just a single specific specimen. Examples of samples that are often used:
One related application which most people would not consider metagenomics, is that of finding circulating tumor DNA in blood to detect tumors.
DNA sequencing milestone Updated +Created
Most of these are going to be Whole-genome sequencing of some model organism:en.wikipedia.org/wiki/Whole_genome_sequencing#History lists them all. Basically th big "firsts" all happened in the 1990s and early 2000s.

Communication mechanism Updated +Created
There are four main types of communication mechanisms found:
  • There is also one known instance where a .zip extension was used! web.archive.org/web/20131101104829*/http://plugged-into-news.net/weatherbug.zip as:
    <applet codebase="/web/20101229222144oe_/http://plugged-into-news.net/" archive="/web/20101229222144oe_/http://plugged-into-news.net/weatherbug.zip"
    JAR is the most common comms, and one of the most distinctive, making it a great fingerprint.
    Several of the JAR files are named something like either:
    • meter.jar
    • bandwidth.jar
    • speed.jar
    as if to pose as Internet speed testing tools? The wonderful subtleties of the late 2000s Internet are a bit over our heads.
    All JARs are directly under root, not in subdirectories, and the basename usually consist of one word, though sometimes two camel cased.
  • JavaScript file. There are two subtypes:
    • JavaScript with SHAs. Rare. Likely older. Way more fingerprintable.
    • JavaScript without SHAs. They have all been obfuscated slightly different and compressed. But the file sizes are all very similar from 8kB to 10kB, and they all look similar, so visually it is very easy to detect a match with good likelyhood.
  • Adobe Flash swf file. In all instances found so far, the name of the SWF matches the name of the second level domain exactly, e.g.:
    http://tee-shot.net/tee-shot.swf
    While this is somewhat of a fingerprint, it is worth noting that is was a relatively commonly used pattern. But it is also the rarest of the mechanisms. This is a at a dissonance with the rest of the web, which circa 2010 already had way more SWF than JAR apparently.
  • CGI comms
These have short single word names with some meaning linked to their website.
Because the communication mechanisms are so crucial, they tend to be less varied, and serve as very good fingerprints. It is not ludicrous, e.g. identical files, but one look at a few and you will know the others.
