I disagree - user-mode code, whether it's separated into threads or processes, still relies very heavily on kernel scheduling decisions. It may sound simple enough, but if you study the decisions the kernel has to make (such as which thread to wake first, from a set of 8 all waiting on the same semaphore), you can find lots of ways to get it wrong. We now take it for granted because thousands of man-years have been spent on solutions.

Comment Re:GCD also replaces most synchronization / lockin (Score 2, Insightful) 205

If you're creating a serial queue anyway, you no longer have parallelism. If you have multiple serial queues, you may as well have had multiple threads with no interlocking between them. This is just yet another API to do what competent parallel system programmers have been doing since the first thread.

Comment Re:People who write in textbooks... (Score 1) 247

I agree. The best students I know don't even buy the books, let alone write in them, because they're actually using the material in practice (hobby, job, overkilling lab work, etc.) and internalise it better than note-taking and highlighting ever could. They look lazy until you see what they can actually do.

In all fairness, when did Microsoft ever have fanfare? Informed computing enthusiasts were sick of Windows after 10 minutes, opting to at least diversify into Apple and free Unix, and nobody else even knew there was anything other than Windows, and treated it as part of the computer.

Now that people realise they have choices, Microsoft is scrambling to do what it never had to do - actually market its operating system - and has shown all of the competency of a high school dropout.

Comment Re:Linux audio (Score 2, Interesting) 374

The real fix would be to make PulseAudio use OpenAL optionally, so that cards that have accelerated mixing can be made to use it. I don't see the point though - not only are modern CPUs more than powerful enough to do it in userspace, they can't possibly have per-card defects while doing it.

Now that we do have PulseAudio it's best to trim as much fat and necrotic code from the kernel as possible. If the remaining realtime issues can be resolved, for which there is much experimental literature, it'll be perfect.

Comment Re:There is no secret patent based plot to kill li (Score 1) 228

Linux and open source in general are a theoretically infinite competition to Microsoft. After a big spike in proprietary models, the trend of all software industries is now towards more open standards, more open software and smaller companies offering small sets of products that together solve big problems. This is exactly where open source most naturally thrives, and it's the exact opposite of how Microsoft has always operated - one vendor, one set of products, nothing open. Microsoft's executives know this, they're not stupid, so they're trying to hold back the trend with patents and faux-open standards like OOXML. It's like trying to hold off a global ice age by burning your house down.
