Hover Your mouse over the left-most image on Wired, and it (probably - depends on browser version) explains that traffic is depicted as skyscrapers, with North America having really big ones. Just the type of imaging effect to use these days, I guess...
I agree completely - but since Bugzilla is licensed under MPL 1.1, you don't mind sharing your improvements with the rest of us? We could really use a bug-tracking system where I work, and Bugzilla is just fine - except for the god-awful UI. I *know* it's HTML and I know my way around HTML just fine, but seeing how this is Open Source I'd rather start from where you have gotten than from where plain Bugzilla starts off. If it's too tailored to your (previous) company, so be it - but I really like the idea of starting at a higher level, and maybe getting inspired by seeing several solutions to the same problem.
Robots today are like computers were yesterday... We are underestimating their use and capability. We just haven't figured out what to do with them yet.
You mean we've figured out what to do with computers? Like Windows, Solitaire and stuff?
My thoughts exactly. Especially since Windows NT/2000 loads on demand (through demand paging). Disk space issues are - for all practical purposes - moot. Run-time image sizes ARE important, but only those parts needed are ever loaded, meaning that it makes little difference for run-time memory usage whether you use a 100 or 20 Kb standard library, since the parts that the (dumb) linker includes unnecessarily are just never loaded. Sloppily written linker, though...
I wonder if there's some marketing gimmick in naming a wireless device after a well-known pain-killer (Treo). Most wireless devices I've tried have regularly been so furiously limited that I had to use pain-killers after using the device...
I've got an infrared device built into my PC, and I use it to HotSync my Palm Vx. No risk of frying anything from static in serial lines or design flaws in cradles, period. Just pull out the stupid serial cable if you're worried and put in an infrared device - they are not very expensive, and installation is a no-brainer to the average/.'er. It's way faster too, but nowhere near USB speed though...
Besides, the gizmo factor of your PC would go up a bit:-)
He believed that under an exteremtly intense magnetic field, objects that are not normally magnetic can be induced to emit a field
Wait a minute - how is that different from "Everything is magnetic, provided that it is influenced by another magnetic field?". It's been a while since I took physics in high school, but my caffeine-starved brain seems to recall that the force a magnetic field exerts follows an inverse square law. In essence, this means that everything is subject to a magnetic field, so the top quote boils down to "Everything IS magnetic". Possible, but not in lieu with current laws of physics (as my limited understanding goes). Or maybe the effect of very small magnetic fields on "non-magnetic" material is just too small to measure, leaving us to sub-divide matter into classes of "magneticity"?
If I'm talking through my butt here please correct me - don't flame.
Diesel locomotives use a hybrid arrangement because a pure diesel locomotive would have trouble moving away from rest smoothly (imagine changing gears on a locomotive)
Actually trains doing just that do exist - the Danish IC3-train does away with the hybrid arrangement, and have had no problems with gearboxes or lack of smoothness. It's called a Flexliner by Amtrak, by the way. See amtrak's page for more info.

About discovering method names - that's a classical problem in all distributed systems. I know that SOAP guys have tried to solve it by using UDDI (Universal Description, Discovery and Integration standard) - IBM just released open source for UDDI. If you like, you can download it from IBM's open source sub-site.
Look at XML Schema for how to use datatypes in XML. I think I get your point about datatypes, but conventional programming does not force you to state the type of your actual parameters, only the formal parameters. Why should an XML-based approach be different?
I know that we're actually suppose to discuss XML-RPC, but it is really only the obfuscation that separates it from SOAP, and I agree with previous posters that SOAP is likely to be adopted instead of XML-RPC because of industry backing.
And, it doesn't depend on gravity. The vibrations is what cause increased bone density (not growth).
OK genius, how do I feel the vibrations in zero G? I'll just drift away from the vibrating plate since the vibrations are the result of the plate exerting a force on me, directed away from the plate. With nothing to hold me back, I'll not feel the vibrations. That's why it depends on gravity. As other posters stated, rubber bands of some kind would solve this problem easily. An even easier solution would be to make a vibrating device that fits inside an astronaut's shoe. VibraSoles?
An entirely different approach would be for Corel to port.NET to Corel Linux, widely known as being imcompatible with the wider Linux world. This would make it real hard to port it to another distro. Now MS could claim to have ported to Linux (it would even be somewhat true) and the unenlightened would see Corel Linux as the 'Linux-that-can-run-my-rented-MS-apps', and forego the *real* distros. Is that classical Microsoft extend-and-embrace or what?
Nice, idea, but floppy technology is still the oldest, slowest, an least reliable part of computers today.
No - MS Windows is:-)
Even if this works, would you not still be bound by the transpher rate of the floppy bus? Is that not the most pathetic thing in the world? semaphore can move bits faster than that...
Seriously, read the article - this thing will connect via USB. No floppy bus to be bothered by.
I've been running Visual Studio.NET beta 1 for a while now, and the only real improvement over Java that I've found is the ability to subclass in different languages. If I design a class in C#, I can subclass it in VB.NET (which is nothing like Visual Basic of old) seamlessly. This is a really cool feature IMHO. At work we do numerous development projects in more than one language, and this could prove to be a much better way to integrate languages than other techniques (COM/DCOM, CORBA etc.).
The other features of.NET are so similar to Java that it's embarassing to listen to the hype around.NET as an innovation. I tend to think of it as what Java should have been all along, and practically *IS* with J2EE, cross-language subclassing aside.
There's nothing to stop that - it has been done a number of times, but never very successfully, if memory serves me correctly. Can't seem to remember what languages, but Pascal was one of them....
is it really scary that children aged 2 to 5 average 27 minutes at the computer? I mean, these are kids that should run around getting all dirty and tired from doing physical stuff. At that age I fail to see the relevance of computers, and it is harmful for the little ones to spend too long in front of a computer. Studies have shown conclusively that when school starts it is the children with the best motor control who get the best start by far - not those who have survived 8 hours straight in Quake 3 or something.
Computers are tools, and for some tasks they are truly awesome. But they are tools that require some skill in logic, reading/writing, math and other stuff to use well, and these skills are not present in 2-5 year olds. Let the kids be kids while they have the chance, and let them play with computers AFTER they aquire the skillset needed for that.
I'm not peddling a Luddite (sp?) view here - I just think that 2 to 5 year old kids should not be in front of a computer. They should explore the physical world instead, and once they're properly prepared they should most definately become literate computer users (and hackers:-).
I had a physics teacher in high school who could explain any and all facets of physics to anyone who was moderately interested, and who would explain whatever part of physics you ever inquired about, in or out of class. He was the kind of guy who could make physics seem like the most exciting thing on Earth, and his classes (including mine:-) were always in top 10 gradewise in my country.
In computer school I had a teacher who taught us the fundamentals of algorithm design, algorithm analysis and optimization, data structure design principles and stuff like that - basic computer science. He could to it in a way that made it perfectly obvious to almost everybody how things worked. He just knew how to explain things, I guess. You could ask him anything about computer science you liked, and he'd find you an answer. Great guy.
For a couple of months, our regular professor in mathematical analysis (a regular Mr. Boring) was hospitalized. During that period, some other guy from the math department took over, and we were swept away by his passion for math, and his ability to explain even the trickier parts of proofs with simple drawings, analogies and just plain good explanations. For two short months, math was very exciting, fun and downright entertaining.
The latter guy is probably the most awesome of the three - I mean, I liked *math*. I've always liked physics and computer science, and math was just a necessary evil to support the two. But for two months, I really enjoyed learning math...
For overall coding efficiency and insight, I warmly recommend "The Pragmatic Programmer". Not linked to any programming language or paradigm in particular, it explains the secrets of the trade in clear and concise terms. I have given this book to others regularly, and rookie and veteran coders alike benefit from the advise in the book.
... Yeah, but look at Io. Obviously Europa doesn't have that particular level of insane tidal forces, but there's probably enough to do something...
That's true. Io is one weird place. But I seem to remember hearing that the four (or something) innermost moons of Jupiter are within its equivalent of our van Allen belts (the Jovian ones are HUGE because of its enormous magnetic field), peppering them with radiation enough to make them sterile if they had Earth-life on them. Perhaps some very hardy bacteria (like those that survive inside some nuclear reactors - talk about tough) could live there, but in my book this further lowers the chance of life ever forming on its own. But maybe the packice of Europa protects it from that - I don't know.
... I don't have enough info on Jupiter's moons' orbits to hazard a guess, though...
Look here for more info on Jupiter and its moons. But Europa is VERY close to Jupiter - just 670000 km away according to the aforementioned website, just roughly four times the diameter of Jupiter. That'd put Luna at about 50000 km distance instead - talk about tidal waves! Besides, that would put the moon just inside the outer magnetosphere of Earth, giving Luna a good dose of radiation on its own.
Any idea what the minimal size of eCos is when it has Posix 1003.1 support, a fully functional TCP/IP stack, ethernet driver, RAM disk? I've been using uClinux for a while, and it weighs in at around 500-600 Kb (including all buffers), but that's a fully functional Linux system with inetd, telnetd, a shell, a couple of mounted NFS shares etc. I like it a lot but if I can get one that's smaller, I'd like that better:-)
I can answer a) with a 'yes' - look at the RedHat training & certification program, for instance. I've heard that other distro providers offer something similar, but I've only looked at RedHat so far - maybe I'll take a GNOME programming course and certification myself once I convince my boss that I need that enough to make him cough up the dough.
How about Europa? Out in the middle of friggin nowhere, totally encased in ice, yet there is considerable thought by Those Who Know that there may be life underneath it.
I should point out the the conditions in which life first formed here were pretty disgusting themselves. [snip] Not fun. Those tidal pools were simply a little less god-awful than everything else.
"Those Who Know" would be "Those Who Make Good Guesses", right? I totally agree that it is *possible* that there is (or were) life on Europa from what we know of it right now, but until someone lands there an checks it, I'll hold my bets (didn't Arthur C. Clarke make someone go there for water in 2010, only to be attacked by some amorphous lifeform?). You see, Europa is short on one crucial thing - readily available energy coming in at a steady state. As you put it yourself - in the middle of friggin nowhere, totally encased in ice. What energy penetrates a thick layer of ice? Not much - I seem to remember hearing that if Europa is warm on the inside it is probably due to tidal forces from its planet, combined with the good insulation of the ice. Don't underestimate the tidal force of a gas giant but tidal forces are gravity, and gravity (or the low-termperature but widespread heating it most likely causes) is not a very high quality energy-source - certainly not compared to the high-quality energy provided by the sun, that Earth receives so much of, at least compared to Europa.
I'm not arguing that there can't be life on Europa, only that it is less likely to form there than on an Earth-like planet because of a dearth of high-quality energy. But these are mere guesses, and I sure hope Arthur C. Clarke was right about Europa:-)

I suppose a geographer could look at the slashdot effect as equivelant to a 'random natural disaster' when mapping out the web.
It's hardly random - in fact, it's highly predictable that whenever some poor website gets highlighted on /., it's basically doomed...
