Honestly, these days a computer might last 10 years without being hopelessly outdated. 2 decades ago, there was no point in building a PC for it to last, it would be obsolete in 3 years. Now it a good time to buy quality components. Start with a reliable power supply, a great case, high-quality disks (they do exist) and so on. Use RAID if you can (at least a mirror) and do backups. Your data is more important than your hardware.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Apple is not for gaming, that's it.
Like most engineering problems, once a solution exists in prototype form, it looks like a solved problem to the marketer. In reality, there is a big distance between something that sort of works in ideal conditions and something that is really reliable under most conditions. Driving safely and efficiently is a difficult problem, at present requires expensive sensors and a lot of computing. It will get cheaper and easier and more reliable and will probably be useful. However I think we will still have a full set of manual controls in cars for decades to come.
Actually, computer vision, in terms of difficulty, is indistinguishable from strong AI. Look up the term "AI-complete".
Learning to fly a small airplane requires a lot of money and dedication. Only a tiny minority can do this at present.
What is the material, labor and recycling cost of doing so ? Lack of space is likely not the blocking issue with solar. Google probably has the answers.
Sunlight? What's that?
Science gets things wrong all the time. In the pursuit of the understanding of Nature, we only have a few reliable tools. One of them is modelling. Nature so far has resisted all attempts, and so all models are wrong at some level. However some are useful.
The general thinking is that we will never have a perfect understanding of Nature, and so Science will never be completely right and completely finished.
I think the GP's point was that if a watch is really expensive then a thief will not stop at cutting off your hand to get it.
Short answer: no.
Longer answer: figure 37.3, page 1014 of "Gravitation", by Misner, Thorne & Wheeler (classical text on general relativity).
Long answer: this thesis..
In other words, it requires GRT to be correct. Which is precisely the point.
The idea of the experiment is described in Misner et al (Gravitation, Misner/Thorne/Wheeler), and a comprehensive explanation of the LIGO experiment is given here, in this Caltech course. But feel free to disprove Kip Thorne and all the others professional physicists who have been working on this experiment for decades, by all means.
Exactly, whereas somehow the fossil fuel shills are seen by some as the good guys. This may be because somehow no one want to own up to the fact that they are responsible for some ills of the world. Not me with my little car !
Doesn't really. current IP laws do not protect new, aspiring authors or small companies. They protect established players. Same as most of the rules actually. This is one of the reasons why when you create a company you have to become big fast. The fastest to grow big wins.
It seems hard to believe that Africa will sustain 4x more people than now given the state the continent is already in.
There are globally close to 2 billion people and growing with their own computer, power plug and working flushing toilet. 400 millions in North America, 500 millions in the EU and surrounding countries, plus Russia, plus Japan, plus Korea, probably at least 100 million in China, 100 million in India, and smatterings everywhere else. This works out to about 25-30%. Nowhere near the 1% the GP is referring to.
