Irrelevant. Just because a person copies "public static void main" out of example 1.1 in Learn Java in 24 hours doesn't mean they understand what it means.
By that logic, you don't need to know how to program at all, you can just copy full programs from open source projects
That doesn't follow, at all.
The underlying argument is that Java requires more "advanced" programming structures to do simple tasks than Perl.
That's an inaccurate generalization, that is only supportable by two minor instances:
there are no functions, only methods (ie. all procedures must belong to a class)
The entry point of a program happens to be "public static void main" in the class invoked by the interpreter. This is more or less a consequence of the above.
Nothing else else about Java fundamentally requires more "advanced" programming structures than C++ or Perl.

"Doesn't look like you need to know much about inheritance, polymorphism, and static class methods to me." -- says the man as he defines a static class method.
Irrelevant. Just because a person copies "public static void main" out of example 1.1 in Learn Java in 24 hours doesn't mean they understand what it means. I would wager that 90% of Perl programmers who use "my" regularly don't have a clue about lexical vs. dynamic scoping, but it doesn't matter because "my" does what they expect.
I can definitely appreciate the desire to avoid vendor lock. However Myricom has not placed any artificial barriers in the way to keep people from competing with them. Myrinet is an ANSI standard, just as open as Ethernet. It just happens to be much more expensive to produce hardware and software that performs the way Myrinet does than to make Ethernet NICs and drivers.
Another option is to wait for 10gigE (along with the rest of the supercomputing world) or go with Myrinet, which has recently broken the 1 gigabit barrier.
Recently? Myrinet has been doing 2 gigabits full-duplex since May 2001 when it started using fiber. Not to mention that full link utilization only uses a few percent of the host CPU. What's the point of fast cluster interconnect when you use half your CPU sending packets through the TCP/IP stack?
They just dimmed the lights, telling people to leave as the first day of the exhibition floor draws to a close.
McNealy's keynote focused on establishing the image of Sun as a significant supporter of the open-source community through efforts like OpenOffice.org. He also said they are committed to LSB support for their Linux distro, and they have no intention of establishing incompatibility. I thought the most surprising announcement he made is that Sun is introducing the LX50, an **X86** server! He said they will ship with both Linux (Sun Linux I assume) and Solaris, leaving the user to choose. He didn't say much of anything about Sun ONE.
He said one of Sun's strategies will be to make their products "Integratable," as opposed to "Integrated." The idea being that you have the ability to swap out any part of their software and use a different product -- free or proprietary -- in its place. He contrasted this with Microsoft (whom he mocked throughout) who "swore under oath that if you remove this one little program (the web browser) the whole thing will break and they'll have to take it off the market."
I saw the Google guy's (can't remember his name) keynote also. Can't think of anything to say about it, a lot of it was just "we have tons of computers, here are the problems we face."
The Microsoft booth is plugging a new product of theirs called Services for Unix. Win32 works as a subsystem of the NT kernel through an undocumented interface. Services for Unix is an implentation of POSIX (with SysV IPC, shm, pipes, mmap, signals, etc) that works at the same level as Win32, as opposed to Cygwin that runs on top of Win32. Pricing is $99, $39 academic. The current version doesn't support pthreads, but the next one will.
The Microsoft booth reads "Community. Interoperabilty. Flexibility."
As one of the authors of Audacity, I'm glad to hear you like it! Re: effects, our development version allows you to use LADSPA plugins, giving you access to Steve Harris's excellent plugin collection.
I agree that fragmented audio APIs are a problem. I am an advocate of PortAudio, a well-designed audio i/o library that provides good performance on several platforms. It supports (or support is in development for) OSS, ALSA, ASIO, WinMME, DirectSound, JACK, CoreAudio (MacOSX), MacOS9, and sort of BeOS. It doesn't do MIDI, but hopefully some day PortMIDI will.
VST is a problem because though it is theoretically platform-independent, plugin writers write windows-specific stuff into their plugins anyway.
LADSPA is a widely-used plugin format on Linux, and Steve Harris has written many high-quality plugins for it.
or some of the other 10,000 apps on Dave Phillp's Linux Sound and MIDI Apps page
That didn't come out quite right. I meant to add that obviously not all of these are mature, usable programs; however it is constantly becoming easier to find free software to fulfill your sound/MIDI needs.
I wouldn't dream of switching from a Mac or Windows until you could get a version of Cakewalk, Logic, or Pro Tools on it.
Before long there may be free software projects that will be just as good if not better than the commercial competition. Ardour's stated goal is to make ProTools irrelevent, and the project is led by the extremely clueful Paul Davis. It's undergoing active development, though it supports many features right now.
MIDI seems to be a weaker point: MuSE and Rosegarden are two sequencers I know of, but I've never tried them.
The first time I remember seeing this joke was when Eazel was going under, and it was something like:
1. Write a file manager and give it away for free 2. ??? 3. Profit!
But I went searching for this post yesterday and I couldn't find it in any of the eazel-related stories. So can anyone clear this up? Who posted this joke the first time, and when?
Great news Bruce! A few questions about it...

HP Backs Off DMCA Threat
·
· Score: 3, Interesting
Bruce,
Anything else you can tell us about this fortunate reversal? Were you involved in knocking some reason into those responsible? How did the people in power originally decide that it would be strategic to weild the DMCA as a weapon against disclosure?
Wow! So cutting edge! Suse 8 had KDE 3 ages ago, now Slackware 8.1 is out and has it, and we should be excited that Debian has finally come out with support for a now quite obsolete version of KDE.
The day that Suse or Slackware provides working binaries for 10,000 packages on 11 architectures it might actually be relevent to make comparisons like this.
Not to mention that the point of this statement was that KDE is being included in Debian for the first time, since last time Debian made a release it was illegal to distributed KDE linked with QT. Not that any other distros gave a shit about what was legal, and even more amusing was that everyone accused Debian of being biased against KDE, a claim that was dispelled by Debian's instant willingness to include KDE once the license on QT changed...
Written like a true poseur!! Tell me, kid, do you know how to write software?
Yep. I've written a significant amount of code for Audacity and PortAudio, and plenty more small patches for other projects along the way. I'm also in the process of writing this introduction to the ALSA API, filling a void where little good documentation exists. Not to mention that I'm working in the software department of a successful computer company.
Listen , I am a professional person and I expec to be paid for my work.
That's wonderful. I am a programmer and I expect free access and distribution rights to the source code of any software I use on a regular basis. There's enough good free software around that I can require this of the software I use and still find programs to do everything I need.
Not that I'm opposed to you being paid for your work, but I'm not going to be the one paying you, especially since paying for proprietary software gets me a worse deal (no source code, no redistribution rights) than downloading free software for free.
You said it, BitKeeper. It's there, it's very good, don't people have anything better to do than nagging about other people just charging for their own work?
Yep, I do actually. It's called writing free software with free tools on a free OS and refusing to waste a minute of my time investing money or effort into proprietary software that does nothing but limit me and control me, leaving me at the mercy of a company's whims and the size of my bank account.
Don't you have anything better to do than try pushing proprietary, expensive software to a group of people from whose work you derive uncompensated benefit?
How do you avoid business pressures to make short-sighted solutions, and consistently make good, common sense ideas work instead of adopting ones from marketing sources? [...]
Craig:
You know, it's this kind of cruel, hard-hitting question that gives the press a bad name.
Huh? The question, paraphrased, was "how does Google manage to not suck when so many lesser companes suck?" The question is very complimentary of Google! I don't understand how Craig construed it as "cruel."
Using packages optimized for Pentium and higher class CPUs yield up to 50% increase in speed
Prove it. It's that simple. Debian could create a k7 or i686 version of the distribution if it was shown to be compelling, but no one has ever offered anything more than vague and unsubstantiated claims of wild performance improvements.
So prove it. You could be famous. Find several real-world programs that run 50% (or even 30%) faster when targetting i686. If not, shut up and stop blowing hot air.
This kind of thing won't appeal to real professional musicians as there is absolutely no professional grade multitrack recorders / sequencers available on Linux - not even ONE.
Since you're in the know, could you explain this to me while you're at it? It validates as XHTML 1.0 strict, but its behavior doesn't make sense to me.
I have zero experience with Mozilla's development, so I thought I'd ask for advice before spamming bugzilla...
Mozilla incorrectly renders this w3c CSS1 "float" test. How do I determine if this is known: what kind of bug do I search for? If it is not known, where and how should I file it, or should I report it to a Mozilla insider to file for me?
First off, we need to clear out an issue that many people are confused about or just do not fully understand. VMware Workstation & VirtualPC are not emulators as Bochs is. They deliver the same output, but the way they work is different.
[...]
VMware Workstation buys speed with its runtime engine, while Bochs and VirtualPC buys portability. It is a trade-off game.
Some gripes people have had, for instance (a) wasn't GPL and (b) binaries need to be compiled on a specific machine for optimization--both are moot points now! They are now fully GPL

for amateurs, maybe. audio professionals (who are, after all, the people we're talking about) wouldn't touch Linux with a 39.5' pole, and rightly so.
