In a previous blog, I talked a bit about the hazards of coding to an implementation and not a specification, based on 1980s home computers. While the specifics and peculiarities of that case is hopefully confined to old hardware, the lessons are still worth contemplating. There is a modern variant of this phenomenon that is based on open-source software, and that I must admit to feeling a bit annoyed by. Fundamentally, the question is this: when figuring out how to use an API – should you look at the documentation or the implementation?Continue reading “Don’t Look behind the Curtain! (Please)”
S4D 2012 – Notes
Last week, I attended my fourth System, Software, SoC and Silicon Degug conference (S4D) in a row. I think the silicon part is getting less attention these days, most of the papers were on how to debug software. Often with the help of hardware, and with an angle to how software runs in SoCs and systems. I presented a paper reviewing the technology and history of reverse debugging, which went down pretty well.
Jan Bosch: Software Provocateur
Last week, I had the honor of presenting at and attending the talks of the Lindholmen Software Development Day. The first keynote speaker was Professor Jan Bosch from Chalmers, who did his best to provoke, prod, and shock the audience into action to change how they do software. While I might not agree with everything he said, overall it was very enjoyable and insightful talk.
