Brian Brazil and the team behind the ultra-free gNewSense Linux distribution have released a beta of the forthcoming 2.0 (or Deltah) series. gNewSense is based on Ubuntu but strips the distribution of non-free components to provide users with a truly free operating system. gNewSense is backed by the Free Software Foundation. Among the changes in this release are that gNewSense is now based on Ubuntu Hardy released

last week; the distribution has new artwork; the browser has been changed from Firefox to Epi

phany, the Gnome browser; non-free GLX has been removed from X/mesa; and there is now support for Debian source packages.

gNewSense can be downloaded here or here (torrent).

gNewSense is derived from Ubuntu, and thus has most of the same functionality. There are a number of differences though.

Andrew Binstock and Donald Knuth converse on the success of open source, the problem with multicore architecture, the disappointing lack of interest in literate programming, the menace of reusable code, and that urban legend about winning a programming contest with a single compilation.

Knuth enthuses about Ubuntu and FVWM, sees little future in multi-core programming, and regrets that literate programming isn’t more widely liked. He also forswears unit testing, but the right to skip the testing phase is kind of something that you have to earn.

“Have you been surprised by the success of open source since that time?

Donald Knuth: The success of open source code is perhaps the only thing in the computer field that hasn’t surprised me during the past several decades. But it still hasn’t reached its full potential; I believe that open-source programs will begin to be completely dominant as the economy moves more and more from products towards services, and as more and more volunteers arise to improve the code.

For example, open-source code can produce thousands of binaries, tuned perfectly to the configurations of individual users, whereas commercial software usually will exist in only a few versions. A generic binary executable file must include things like inefficient “sync” instructions that are totally inappropriate for many installations; such wastage goes away when the source code is highly configurable. This should be a huge win for open source.

Yet I think that a few programs, such as Adobe Photoshop, will always be superior to competitors like the Gimp—for some reason, I really don’t know why! I’m quite willing to pay good money for really good software, if I believe that it has been produced by the best programmers.

Remember, though, that my opinion on economic questions is highly suspect, since I’m just an educator and scientist. I understand almost nothing about the marketplace.”
