In case you’ve been living under a rock the past few days, Kim Dotcom (of Megaupload infamy) has launched his new cloud storage site, Mega. Mega has an impressive sales pitch, promising secure cloud storage where only the user has the key to decrypt his or her files, and the encryption and decryption happens securely…

Today, pretty much everyone has a CPU, a DSP and a GPU, buried somewhere in their PC, phone, car, etc. Most don't know or care that they bought any of these, but they did.
A couple nights ago I was looking over the UEFI spec, and I realized it shouldn't be too hard to write UEFI applications in Rust. It turns out, you can, and her…
Yesterday, one of our customers let us know about significant performance issues they have experienced on Heroku. They raised an important issue and I want

fish 2.0 is now released! fish is a fully-equipped command line shell (like bash or zsh) that is smart and user-friendly. fish supports powerful features like syntax highlighting, autosuggestions, and tab completions that just work, with nothing to learn or configure.
With the arrival of core.async , ClojureScript provides a powerful advantage over other popular compile to JavaScript languages like CoffeeScript , Dart , and TypeScript . These languages fail to address the single largest source of incidental complexity for any sizeable client side application - concurrency. In my…
Cassandra is a Dynamo system; like Riak, it divides a hash ring into a several chunks, and keeps N replicas of each chunk on different nodes. It uses tunable quorums, hinted handoff, and active anti-entropy to keep replicas up to date. Unlike the Dynamo paper and some of its peers, Cassandra eschews vector clocks in…

Buffer overflows, stack smashing, integer overflows — C has many well publicised flaws, and these terms are often bandied about confidently, even by those unfamiliar with…
This article is in response to an earlier one comparing Haskell and C, which made the claim that Haskell beats out C when it comes to speed. On a Hacker News thread I made the bold claim that the C code is rife with problems and that it is tempting to fix it.
