didn't wake up until 10:00 AM but managed to snag a wii after 4 hrs waiting in line.
i'm utterly pleased with the wiimote concept. terrific system.

shame on slashdot for not covering wii launch day.

I tried to upgrade my ubuntu box for the past 2 nights but the installer
gives up when it can't connect to http://easyubuntu.freecontrib.org/. I'm
not interested in upgrading if it means the non-free codecs stop working.
Anyone else run into this?

Sheesh, RTwholeFA! - He goes on to say, "I travel most of the time, so I don't have a desktop machine, only a laptop. It runs Debian GNU/Linux, which was the best distribution in terms of respecting freedom as of the time we set up the machine."
So it's more of of nudge, I'd say, than an "awful stab"... --TRR
targeting multiple platforms encourages better software design and uncovers flaws and weaknesses that might get swept under the rug, so to speak, or ignored in a monoculture.
the quality of software which has been ported to a diverse group of compilers / frameworks / runtimes should improve, not suffer.
would it be so much better to restrict system software choice to linux than, say nt? and what about code forks (which are not a problem in the nt world)?
aol/tw ought to offer a rebranded version of this, integrate it with their services (emphasis on aim), and send out these things for free instead of the damned cdroms (including a net installer for their pc & game console software in the im device).

Sakurai books are concise and essential. They used to be known a "black sak" (_modern qm_) and "red sak" (_advanced qm_), although nowadays they both sport red covers.
When building for the synthetic Linux target, the resulting binaries are native Linux applications with the HAL providing suitable bindings between the eCos kernel and the Linux kernel.
Note: Please be aware that the current implementation of the Linux synthetic target does not allow thread-aware debugging.
These Linux applications cannot be run on a Windows system. However, it is possible to write a similar HAL emulation for the Windows kernel if such a testing target is desired.

(btw, an animated web demo of your system like the one I linked to would be insanely neato)
a Nd:YLF pumped diode laser was used as the first stage for the current Omega laser due to its wavelength being readily absorbed by solid hydrogen (I would guess) and its relatively high output. it's wavelength lies in the infrared with green and ultraviolet harmonics. some beam splitting and amplification/acceleration is involved with the production of the final pulse.
this laser also seems to be popular photon source in imaging devices for which has replaced expensive and bulky TiSaph equipment in many applications (or so think i read). so . . .
question for slashdot: will the basic technology for the petwatt upgrade be the same?
sorry no links - go hit up the search engines yourself (i refuse to say "google" as verb). . . oh, what the heck:
Although the UML is especially useful for OOD (which itself is not necessarily OOP - consider X Windows which is very OOD but composed of C functions) it was designed to be universal by basing it on an extensible a meta-model (which encapsulates the paradigms, a'la smalltalk).
Also, some of the key pieces of UML are quite useful for any programming paradigm - (eg use cases are probably the safest and most efficient way of analyzing software requirements as well as designing validation tests, regardless of your particular system (a point I'm quite willing to argue at length); another case in point is sequence/timing diagrams which work just as well for assembly language programming as for OO or functional languages).
What to do about poorly documented legacy code? Well I've been involved in a couple of C code design capture efforts. Compared to OOD, the class diagrams came out rather boring and featureless (trivial data classes and great big class utilities). But they gave an exact design specification for the system (very useful for maintenance, incremental enhancements, and training future maintainers).
So which language was your instructor using to demonstrate OOP?
Finally, the less you know about the design, the more difficult, time consuming, and costly the task of trouble-shooting/maintaining the codebase will be.
The lack of a stable notation for software design has allowed many people to re-invent the wheel many times in software related fields.
Hopefully widespead adoption of UML will put a stop to the notion that the new guys are onto to something new (when most often what they've come up with just a new way of looking at something).
A skilled engineer is someone who knows how to architect a model or design from a set of requirements. How to create the blueprints (or in the case M$FT, bluescreens:^).
Coding (not to be confused with integration)) should be trivial, piece-work, 90+% of the time for anyone with 0.5 brains.
