What will you do if the 1000 tests takes 10 hours?
Either ctrl+c, or try it 10 times.
Why 10 times? Maybe 5 times is enough or at least 20 times is required?
It doesn't have to be statistically accurate. It just has to be close enough.
How do you know that you are close enough?
One can do a benchmark a couple of times to see whether the results are more or less the same. A more sophisticated approach is to measure the standard deviation as well. However there are situations where accuracy is critical. In that case one makes a distribution assumption (e.g. Normal distribution) and then a statistical estimator is used to give a confidence interval for the estimated parameter. I.e. the confidence that the parameter will be within that interval is 95%.
I bought an unlocked second hand Motorola phone for 40£ in a shop. Note however that GSM in North America uses different bands. I.e. your phone needs to support this and you may have to change the configuration settings.
Another interesting (but proprietary) project is Maglev. The idea is that you write programs in Ruby and the virtual machine gives you persistence and clustering for your variables in a transparent way.
I thought they were working on Drizzle. But suggesting to the EU to force Oracle to relicense MySQL under the Apache License after having it sold to them (indirectly) doesn't exactly sound like a neutral point of view;)
The question is: Will Mono further the cause of FOSS or not? If you are a developer doing cross-platform development under GNU/Linux, there are always two possible outcomes:
users will stay with the proprietary operating systems (Windows,MacOS) because your software runs very well on that platform anyway
users will switch to free software because your software makes them realise that there is a whole world of free software out there
Especially in the first case it is important to get the licensing right. KDE4 for example is being ported to Windows, MacOS, and Solaris. If KDE4 would be licensed under BSD/MIT instead of GPL, Microsoft or Apple could simply take the work and sell it as part of their proprietary software. The monetary gains then would be used to take control of the project.
My fingers instinctively groped for the keyboard when I saw the asteroids entering the picture. I find it alarming that the large asteroid is faster than the small one.
Or a Slashdot forum with less than 50 postings. That's what you get when you ask such a question.
And while we are at it. We also welcome * suggestions on how to improve support for proprietary software * input for the banks on how to increase capital gains * proposals for improving the safety mechanisms of guided missiles
Yes. If it comes out that you are massaging the data in e.g. the field of molecular science it will cost your job very quickly. But the peer pressure is very high on researchers who are saying that anthropogenic CO2 has a minor effect on the global temperature. Gordon Brown for example calls them "flat Earth group".
All he wants is a tête-à-tête with Sergey Brin and Larry Page so that he can talk with them about our faith and the future of mass media. Almost every influential politician has granted him that. Sergey and Larry are just the new kids on the block and they better pay him some respect if they want to become members of the club!
Analogous to the EIF's definition of Open Source Software (OSS), paying taxes is the willingness of persons, organisations or other members of a mixed source community obtaining salaries to share information about their financial status and to stimulate a debate with the revenue authorities, having as ultimate goal a mutual understanding of the situation and a strong basis for a healthy debate. In that sense, paying taxes leads to a quick turnaround of our fiscal status and strengthens the economy.
You are right. In a self-contained system you can choose your own time base of course and absolute time is not important (only relative time). However I think it does no harm to be aware of those things.
Anyone who thinks that measuring time is simply a matter of using accurate floating point values should have a closer look at the definition of time
There is the universal time (UT) where there is noon when the average sun crosses the zenit in Greenwich.
There is the ephemeridal time (ET) which is a constant time measure which was defined last century. Due to the earth's rotation slowing down ET-UT is more than one minute these days.
There is UTC which is a constant time measure which is aligned with UT (running at the speed of ET). Once UTC-UT reaches 0.9 seconds a switch-second is introduced (happens about twice a year).
Then there is time zones and all the summer time / winter time nonsense
A year has more than 2**34 milliseconds. The Julian calendar starts at 4713 BC. In order to save digits time-signal services use the Modified Julian Date which starts somewhere in 1858.
And depending on the problem you are working on you may have to take into account relativistic effects caused by the gravitational potential of the earth and the sun.
When Obama's inauguration speech was published using Silverlight I thought that the Whitehouse IT had succumbed to Microsoft lobbying. So this actually good news for once. Lobbyists will have to be more careful in their rhetorics when arguing against free and open source software.
A tiny black hole wouldn't gobble up the earth as newspaper scare stories would have one believe. Instead the black hole would disappear in a puff of Hawking radiation and I would get a Nobel prize.
He is just doing what he does best: Spreading FUD and steering public opinion. Some time ago there was an interview with the very same Murdoch proudly explaining how the purchase of MySpace would transform his media empire. But he would rather see a world in which Google faces strong mistrust by people and their governments. That's why he is spreading this nonsense. What an imposter!

Here is a beta release of the new Google Streetmap.

20 million DSL subscribers which happen to be among the most attractive in the world
Google would definitely loose out if they would remove the pictures of the most attractive DSL subscribers in the world ;)

Eben Moglen just released the article The European Commission and Oracle-Sun.

Yeah. The previous poster probably also had problems with the Slashdot comment filters. I had problems to post code examples in the past.

It's probably going to be something like the Florida Voting Machine.

Can you please post a corrected version for us so that we can learn from you?

Sorry, but this is not the right tool to list FOSS experience. Next!
No. But you can see a black hole by the way it distorts the sky around its edges.
Here's what Hawking said when giving his Michelson-Morley award lecture:
If somebody is interested in vision using "neural networks", I can really recommend to watch Geoffrey Hinton's lecture on Restricted Boltzmann Machines.
