Next week (June 7) is the election date for the EU parliament for the next five-year term. As a citizen of the EU and Sweden, I feel it is my civic duty to vote… but the quality of the election campaign so far does not exactly encourage it. As in many other EU countries, the EU and its parliament feels like a distant power hard to affect, and the EU election process tends to be more about domestic issues than true EU-level issues. Even so, there is one relevant, interesting, and burning topic that has come to the fore. Intellectual property rights and “media piracy”.
Last year in a blog post on video encoding for the iPod Nano, I complained about the lack of performance on my old Athlon. A bit later, I noted that (obviously) video encoding is a good example of an application that can take advantage of parallelism. Yesterday I put these two topics together in a practical test. And it worked nicely enough.
Another Cadence guest blog entry, about the overall impact of virtual platforms on the interaction between hardware and software designers. Essentially, virtual platforms are a great tool to make software and hardware people talk to each other more, since it provides a common basis for understanding.
Virtutech and Cadence yesterday announced the integration of Virtutech Simics and Cadence ISX (Incisive Software Extensions), which is essentially a directed random test framework for software. With this tool integration, you can systematically test low-level software and the hardware-software (device driver) interface of a system, leveraging a virtual platform.
IEEE Spectrum has an article in its May 2009 issue called “25 Microchips that shook the world“. Not long or deep, but an interesting mix of chips from the 1970s, 80s, 90s, and the 2000s. Recommended as light reading.
FLOSS Weekly recently ran an interview with the creator of the Xen project, Ian Pratt from the University of Cambridge (and now working for Citrix since they bought Xensource). Since I happen to like virtual things, even the so-much-talked-about-it-hurts IT/server/desktop virtualization world this was a must-listen. It was a good show, but lacking some in the humble background department.
Yes, when does hardware acceleration make sense in networking? Hardware acceleration in the common sense of “TCP offload”. This question was answered by a very nicely reasoned “no” in an article by Mike Odell in ACM Queue called “Network Front-End Processors, Yet Again“.
I just rediscovered my first computer, a Sinclair ZX Spectrum (good picture) which I bought back in 1983 or 1984 (I have no trace of the exact date, unfortunately). The machine was a perfect machine to learn programming on in my opinion, consisting of little more than a Z80 processor with memory, bit-mapped display (with a famously odd-ball addressing scheme and color handling) and ultra-simple sound output and input. Most of my friends in the end bought Commodore C64 machines, which had more powerful graphics and sound hardware, but a processor that was much less fun to program.
The Spectrum came with a built-in BASIC interpreter that are up the bottom 16kB of the 64kB addressing space. The BASIC was actually fairly powerful and easy-to-use, and included a very fun programming textbook. I just reread that textbook, and it is quite strikingly well-written and manages to cover both basic computer-science-style programming and deep close-to-the-machine and real-time programming in a compact 150 pages. There is no credit to a particular author in the book I have (Swedish translation by a group of people at Ord & Form here in Uppsala), but an online scan credits Steven Vickers.
I just found a fairly interesting podcast that offers a nice example on how do marketing for paper-based magazines using digital ephemeral technology. The ancient warfare magazine has a podcast that accompanies each issue, where a set of history buffs discuss around the theme of the current issue of the magazine.
xkcd has had a good streak recently. Here is a very good one.
