Arti?cial evolution for self-replicating computer codes has been introduced for the ?rst time in 1990, when Steen Rasmussen created CoreWorld. CoreWorld is a virtual machine which can be controlled by a language called RedCode. This assembler-like language has a pool of ten di?erent instructions that take two addresses as arguments. Rasmussen’s idea [...]
At some level I knew that extensions for Google Chrome ran in separate processes too, but I never really gave it a lot of thought till I was in process explorer today and saw a bunch of chrome.exe processes taking up memory, a little more investigation showed that it was all the extensions [...]
Windows Vista introduced the “Sniping Tool” which removed the need for me to install a third-party screen capture tool (Gadwin PrintScreen was the one that I was using). However I never really thought about the fact that I had no keyboard shortcut for this and was doing Win + “Snip…” to launch it for [...]
Berkeley Sockets (BSD) are the de facto API for all network communication. With roots from the early 1980′s, it is the original implementation of the TCP/IP suite, and arguably one of the most widely supported and critical components of any operating system today. BSD sockets that most of us are familiar with are peer-to-peer [...]

But I don’t see it that way. I always imagine the outcome of eight-ball to be predetermined, to [...]
Pomegranate is a novel distributed file system built over distributed tabular storage that acts an awful lot like a NoSQL system. It’s targeted at increasing the performance of tiny object access in order to support applications like online photo and micro-blog services, which require high concurrency, high throughput, and low latency. Their tests seem to indicate it [...]

While searching yet again for the SQL to find a particular piece of text inside SQL server proc definitions I came across this cool Addin project that does exactly that and also has other cool features like generating the data insert scripts for a table.

perl -wle ‘print “Prime” if (1 x shift) !~ /^1?$|^(11+?)\1+$/’ [number]
This is a nice trick to check if a number is prime using regular expressions, I am going to try and see how this performs compared to regular methods and see if anything interesting comes up.
