Amazing as it may sound, people somehow seemed to survive and even prosper before:
football, bikes, roller-skates, magazines, books, and clocks.
My original comment was not about about whether there should be computers. It was a reply to an oh dear, what am I supposed to do if I can't 'use' the computer? comment.
But the common man doesn't understand 'efficiency gains' as something significant. Perceptually, people don't get how much energy is lost to waste heat.
Just about anyone who buys gasoline and knows that the hood of the car gets hot can understand that if that heat were used to help move the car, s/he'd need to buy less gasoline.
The question at hand is, "What technology would you like to have seen applied in your kindergarten?" "Blocks," and so forth is a perfectly valid answer. What expertise exactly is anyone here supposed to draw on when answering this question, either that way or in the terms you want to see? Your objection to the answers invalidates the entire exercise. If we don't know enough to be qualified to say "blocks", we're not qualified to recommend any particular high-tech doodad as beneficial either.
My wife works in a private dayschool. What do they have?
blocks
costumes
books
simple toys (cars, dolls, etc)
a reading loft
a hamster
audio cassettes with songs and read-along books
lots of construction paper, crayons, glue and child scissors
jungle gym
teachers who actually teach them (depending on age) colors, numbers, alphabet, etc, etc.
One computer that they hardly ever use. I think it's mostly to impress prospective parents.
CVAVR was what my undergrad microcontrollers class (Cornell's ECE 476) used, and I believe still uses.
Except that a Senior-level (4xx is still senior level?) University course is populated by much more technologically advance group of people than a High School class is.
With the release of this Kernel...does this event help us on the desktop front? If so, how?
From what I see, we [on the Linux bandwagon], have a long way to go. We're still playing catch up on in many areas critical to common desktop computer users. I hope some one is listening.
Among the other things mentioned here. It's actually somewhat of a security thing. A lot of root kits and other exploits rely on fixed addresses so if you move the kernel or other parts of the OS around it's harder to hack.
Well hell, why didn't they mention that on kernelnewbies? It would have perked up everyone's ears, even those of us who don't know what kexec is.
Available today on the new GeForce® 8800 graphics card and future NVIDIA Quadro® Professional Graphics solutions
They'd need a demonstration motherboard with, say, an Opteron and 8 or 16 of these theoretical GPU-derived chips that take in a stream of input, and spit out input that is then passed to a different computer for visualization.
Take 3D programming as an example. Before I can render the screen, I have to run thousands of vertices through a matrix transformation so that they align with where the camera sees them. This is a bulk operation that can be run in parallel by multiple SIMD cores (each tranforming 2-4 vertices per instruction) by simply providing each core with a copy of the computational matrix. Simple, straightforward, and FAST. But utterly useless for general purpose code like multithreaded web servers.
I'm wondering why NVIDIA hasn't jumped into this market. Isn't that exactly what modern GPUs do?
The old mainframe has been replaced by Unix servers but the principle is the same.
Don't forget that Unix started as a green-screen timeshare system, not too-unlike the mainframe.
However, the efficient and clever (but expensive) design of the mainframe ( I know both IBM & Burroughs, and maybe the UNCH) was such that tiny mainframes could handle hundreds of concurrent online users.
For one thing they'll nuke Israel, India, South Korea or Pakistan.
That's why we've installed Patriot batteries in Japan and Israel. (I would not be surprised if they are also in ROK, but they have more to worry from massed artillery 20KM from Seoul.)
This world is so economically interconnected that an attack on Japan, ROK or Taiwan (and even Israel) would in essence be a attack on America and the EU that would hurt them more than you can probably imagine.
There is a large difference between Strategic Nuclear Arms, which we fear Iran is pursuing and Tactical Nuclear Arms, of which congress has been mulling over.
This is an excellent point. A 10Mt weapon air-burst over a large city does considerably more damage than a 20Kt underground burst.
Pass a law making it illegal to connect any OS to the internet that cannot be made bot-free.
"Made bot-free"? Reinstalling Windows makes it bot-free.
No, there has to be a NIST standard test for determining how many bots infect an operating system in 2 hours of "typical" surfing. (Determining what "typical" is, and preventing MSFT from corrupting the test are the hard parts.)
Then, pass a law saying that network-providers can not let those OSs connect to their networks.
Graphing calculators are **WAY** over-rated... what you really need is nice slide ruler! Remember.. nothing goes better with a slide ruler.. than a nice pocket protector to put it in! (Ok.. I can now get my former boss of my back... He was always pushing slide rulers on the other engineers).
Not only that, but they don't have batteries to run down, or need an AC adapter.
Very useful for when society collapses and needs to be rebuilt.
in that case, couldn't anyone file a lawsuit against the stupidity of the people who just tried it at home without thinking nor reading the full experimental protocol...
Why not then just convert www.cnn.com/health to a simple list of links to interesting journal articles?
Still, as others have stated, it's always useful to have a basic knowledge of how your appliances work...
My gut response is, "Asswipe! Just becuz you have the mojo to build your own, do you expect every Linux user to build her own?" Good for you, AW, but for Linux to continue to build market share, it needs to be available pre-installed. This may be old news, but it certainly is good news.
I've been using SFF systems for about 3 years now, and getting everything trim in my first SFF box was a royal PITA. So my 2nd box I had "them" assemble most of it. (I added the drives.) The 3rd one I get (if I decide to continue with SFF systems), I'm going to buy the highest-powered, largest-capacity silent system I can afford, pre-built, and not even crack open the case.
Any language that includes signed and unsigned representations of the same type (int or long for example) would in no way benefit from managed memory. It will still be possible to "over-flow" a long in a calculation and without checks on the results, these types of bugs can be just as bad or worse (ie you don't get an obviously broken system; you get a system that sometimes returns a valid wrong answer) to track down and fix.
Then you're still using a bad language.
I have production experience in C (doesn't everyone?), Turbo Pascal, VAX Basic & mainframe COBOL. (Plus SQL, embedded in the language, but we never use floats. Only numerics and scaled integers.)
Both COBOL (because you always use BCD storage) & SQL (the dialect that I use, at least) will always let you know when you exceed range, as do Ada and Python.
Bottom line: there are many languages that protect you from common C errors (or at least raise exceptions when you try to do them). Sadly, they are usually not the cool, hip CompSci languages. Thus, our world suffers.

Go outside. Play a pick-up game of touch football. Ride your bike. Rollerskate.
Read. Magazines, if your brain hurts, fiction to escape.
Take apart a clock and put it back together again.

Use Linux or OSX, like any intelligent person would.

Very true.
But they are big & heavy, and take ages to write out. Slide rules are much more portable and easy to create.

How does Microsoft solve society's problems?
business of dealing drugs (tobaco companies
Tobacco companies (and illegal drug dealers) do "solve" individuals problems. Otherwise, people would not want to buy their products.
possibly fast food, etc)
