In the April 2009 issue of Communications of the ACM, Mike Shapiro of Sun (or should we say Oracle now?) has an interesting technical article about what he calls “purpose-built languages“. The article was earlier published in ACM Queue. Essentially, it is about domain-specific languages. He describes how many of the most useful little languages in use for the developmentof large systems have grown up without formal design, a grammar, or even a name.
In a very roundabout way, I recently got to hear about a cool Sun server feature introduced sometime back in 2003 or 2004: the SCC System Configuration Card. This is a smart card that stores the system hostid and Ethernet MACs, along with other info, and which can be transferred from one server to another.
The Radio Register has a nice interview with Kunle Olukotun, the man most known for the Afara/Sun Niagara/UltraSparc T1-2-etc. design. It is a long interview, lasting well over an hour, but it is worth a listen. A particular high point is the story on how Kunle worked on parallel processors in the mid-1990s when everyone else was still chasing single-thread performance. He really was a very early proponent of multicore, and saw it coming a bit before most other (general-purpose) computer architects did. Currently, he is working on how to program multiprocessors, at the Stanford Pervasive Parallelism Laboratory (PPL). In the interview, I see several themes that I have blogged about before being reinforced…
The Register has a few podcasts in addition to their website, and the one called “Semicoherent Computing” has turned into a very nice series of interviews with interesting people from the computer industry. I recently listened to their interview from September 2007 with David Ditzel of Transmeta fame. He had a lot to say about the history of computing, as well as interesting things on where computing is going. Well worth a listen! Particular interesting highlights…
The SICS Multicore Day August 31 was a really great event! We had some fantastic speakers presenting the latest industry research view on multicores and how to program them. Marc Tremblay did the first presentation in Europe of Sun’s upcoming Rock processor. Tim Mattson from Intel tried hard to provoke the crowd, and Vijay Saraswat of IBM presented their X10 language. Erik Hagersten from Uppsala University provided a short scene-setting talk about how multicore is becoming the norm.

That is just so cool! For us around Stockholm, we can hear Marc Tremblay talk about this at the SiCS Multicore Day on August 31, 2007.
The register report “IBM embraces – wtf – Sun’s Solaris across x86 server line” is a very appropriate headline for something quite surprising. The day before this happened, we discussed the announced announcement and said “nah, it can’t be about operating systems”. The idea of IBM in-sourcing Solaris for x86 just felt like the kind of thing that was in the same realm as flying pigs, freezing hells, and similar unlikely events.
