I recently switched from darcs to git. Here's a “rosetta stone” to help darcs users learn git and a review of some darcs-to-git translation tools.
I am quite disturbed by the recent trend towards greater centralization of the internet, usually under the guise of “cloud computing”. Most users today don't seem to understand the difference between our email system, which is fully decentralized, and services like facebook, which are operated by a single entity. The increasing centralization resulting from these services creates an irresistable target for hackers and puts censorship decisions in the hands of nongovernmental entities ->http://valleywag.gawker.com/5520933/wikileaks-claims-facebook-deleted-their-fan-page-because-they-promote-illegal-acts, which are not subject to the first amendment.

Did you know that the comparison operator in PHP is not transitive? That's a pretty good reason not to use PHP.

$ dig +short -x 220.127.116.11
I'm tired of people talking about IPv6 as if it were the solution to the IPv4 address crunch – when in fact it has caused that crunch by being a horrifically bad proposal which has distracted all attention from any attempt to come up with a better solution.

Bitcoin seems to be getting a lot of attention right now, and I think it's an incredibly clever technical solution to the double-spend problem. I've been interested in proof-of-work ever since hashcash.

Web forms with a “country” pull-down menu (typically containing >150 entries) should use GeoIP to pre-populate it with an educated guess. The country you're physically in is the one that you're most likely to want to enter in the form.
