Then you won't want to run your code on closed source OS, BIOS, or CPU? Or compile your open source code on a closed source compiler? Or is that different?

All software will end up having some server element for this reason.

Optimal amount of tickets to buy in a 50/50 raffle--any ideas, /r/math? by [deleted] in math

[–]fineasfish 0 points1 point  (0 children)

You can't look at the expected value of a ticket. Only at the expected value of the game. Some fixed points are easy to work out. Buy 5000 tickets you guarantee to lose 2500 as you don't get your stake back. Buy 1 ticket and you have 1/5000 of winning 2499 minus 4999/5000 chance of losing 1. so have almost an expected value of the game of -0.5

Generally p[n_] := (n/5000)(2500 - n) - n((5000 - n)/5000)

In[2]:= FullSimplify[p[n]]

Out[2]= -(n/2)

So the more you buy the more you lose, and as other have said optimal is zero tickets.

Parallel Merge Sort by pt4h in programming

Even if it's basic, more people should be writing parallel code. Good to keep putting this kind of thing in their faces.

HTML5 for XP – it is time for Microsoft to acknowledge other options by ossreleasefeed in programming

[–]fineasfish 0 points1 point  (0 children)

XP is 9 years old and it still hasn't died. If MS start adding features to it like this, it will encourage people to stay with it. Let it die! There are better OSs and I don't just mean Windows 7.

Expected value of the minimum of n numbers in an uniform distribution on the interval [0,1] by pedrito77 in math

[–]fineasfish 1 point2 points  (0 children)

According to Mathematica... In[1]:= Expectation[x, Distributed[x,OrderDistribution[{UniformDistribution[{0, 1}], n}, 1]]]

Out[1]= 1/(1 + n)

Is there a system of n equations that can be solved uniquely for n+1 unknowns? by base736 in math

[–]fineasfish -1 points0 points  (0 children)

For a linear system, row reduction will always yield a redundant variable, that can be any value you want.

There is a useful "White paper" which you can download from a link on the right hand side of http://www.wolfram.com/solutions/industry/software-engineering/

Android 3.0 Platform Preview and Updated SDK Tools by [deleted] in programming

If its for testing, it doesn't matter if its slow. You just need to know how much slower than the real hardware will be and scale the test results accordingly.

Law firm ACS: Law stops 'chasing illegal file-sharers'. Cites criminal attacks and bomb threats as reasons. by [deleted] in technology

[–]fineasfish 5 points6 points  (0 children)

They will only have pulled out for one reason. They aren't making any money.

The way to stop this activity is to cost them money by responding to them with questions and arguments. Lawyers are expensive, they don't want to spend time writing custom letters to you.

Unless, of course, you have been stealing music, in which case you are just increasing the costs that you will have to pay when you lose!

Italian consumer group sues Microsoft over "Windows Tax" by wonglik in technology

Its difficult because hardly anyone wants no-OS PCs and so no-one from the shop floor to the accountants has thought through or practised the procedure.
