Turn your PC upside down to boot into Linux (2003)
Finally the ultra low profile memory I was waiting for arrived and so at last I had Windows XP running inside my "Windows XP Box", and one of the most compact Mini-ITX projects ever.

Distributed Systems in Haskell
I recently completed UT Austin's Distributed Computing class, taught by Lorenzo Alvisi. My project partner Pato and I decided to give it a go in Haskell, and ended up using Haskell for all project assignments (Chandy-Lamport, Paxos, and Bayou).

Jepsen: RethinkDB 2.2.3 reconfiguration
In the previous Jepsen analysis of RethinkDB , we tested single-document reads, writes, and conditional writes, under network partitions and process pauses. RethinkDB did not exhibit any nonlinearizable histories in those tests. However, testing with more aggressive failure modes, on both 2.1.5 and 2.2.3, has…

Postgres full-text search is Good Enough (2015)
When you have to build a web application, you are often asked to add search. The magnifying glass is something that we now add to wireframes without even knowing what we are going to search.

Reducing the maximum latency of a bound buffer in Erlang
Recently I came across two great articles on the Pusher blog: Low latency, large working set, and GHC’s garbage collector: pick two of three and Golang’s Real-time GC in Theory and Practice . The articles tell the story of how Pusher engineers reimplemented their message bus. The first take was done in Haskell. During…

Using the OS X 10.10 Hypervisor Framework: A Simple DOS Emulator
Since Version 10.10 (Yosemite), OS X contains Hypervisor.framework, which provides a thin user mode abstraction of the Intel VT features. It enables apps to use virtualization without the need of a kernel extension (KEXT) – which makes them compatible with the OS X App Store guidelines.
