CERN Releases LHC Data

Jamu Re:Nuclear weapons? (41 comments)

No. Even though it's called CERN. The research is very much sub-nuclear. And although the energies are higher, this also means the particles involved decay quickly. Similarly in nature, they're created with high energies, but don't last long. The A-bomb relies on the natural abundance of uranium or plutonium. These are unstable elements that can be triggered into decaying in a chain reaction. The particles at the LHC need a lot of energy to create, and they decay quickly. It's been suggested they could make an anti-matter bomb. You'd need to use a lot more energy making the anti-matter than would be released in the bomb. Anti-matter is hard to store: it will interact with any matter destructively. No one can make anti-matter in enough quantity. Even if they could, and despite the great energy efficiencies, plutonium and uranium is so much more practical, along with some fusion fuel, that the relatively low energy efficiencies of a nuclear bomb, isn't a problem.

Ubisoft Points Finger At AMD For Assassin's Creed Unity Poor Performance

Jamu Re:A highly relevant comment from the previous pos (262 comments)

I suspect that Mantle would run a lot better on the AMD hardware though. DirectX 12 will end up with the most support.

Ask Slashdot: Where Do You Stand on Daylight Saving Time?

Jamu Re:Against DST or against winter? (613 comments)

I would, but it involves having two different homes and switching between them twice a year.

Jamu Re:For it! (613 comments)

Maybe it's the one-hour shift to their sleeping-pattern, twice each year, they object to?

So you want to go to work earlier. Why change the clocks too?

What I'd hate most would be the fact that Greenwich would never be on Greenwich Mean Time!

Researchers At Brown University Shattered a Quantum Wave Function

Jamu Re:umm.. what? (150 comments)

How about if I don't look, but the cat does?

The state consists of a superposition of the cat looking at itself, and it being dead.

Or how about instead of a cat, we put you in the box.

The state consists of a superposition of you seeing an alive cat, and you seeing a dead cat.

Are you alowed [sic.] to look at yourself or does it only work if I do it?

If you do it, it's a superposition. If I do it the cat is either dead of alive.

What if we're both in the box?

The cat is either dead or alive.

It would have been better if they'd gone with Windows 11. One better.

The Physics of Space Battles

Jamu Re:Umm no (470 comments)

No fireballs in space? Wrong! Spaceship occupants need atmosphere.

You'll only get fireballs inside the atmosphere. In space, you'll get jets.

Could easily be solved by not pointing a gun at anything you don't want to lose. How difficult can that be?

The C pre-processor is the duct tape of C programming.

Jamu Re:Actionscript Scoping (729 comments)

The first version was the standard ANSI C behaviour.

i.e. for (expr1; expr2; expr3) statement

was basically the same as

expr1;
while (expr2) {
statement
expr3;
}

Jamu Re:Lua[0]? (729 comments)

It kind of makes sense in C, as arrays are basically pointers. e.g. p[i] == *(p + i)

Jamu Re:Powershell (729 comments)

strings terminated by a binary zero rather than their physical size. Who the hell thought that would be a good idea?

One advantage to null-terminated strings is that there's typical only one format - well one for each character type at least. For length encoded strings, the format depends on the register size, and the endianness of the platform. Of course C does not enforce the use of zero-terminated strings. Not even for string literals.

Jamu Re:Actionscript Scoping (729 comments)

for (int i = 0; i < 10; ++i) { something(); }

I remember when some compilers would treat this like:

int i; for (i = 0; i < 10; ++i) { something(); }

and others like this:

{ for (int i = 0; i < 10; ++i) something(); }

As the standard, for whatever reason, decide to change it. So much for not breaking existing code.

The Disappearing Universe

Jamu Re:Foolish (358 comments)

I am not saying we will find FTL travel method - but they are assuming we won't which is foolish.

There's a lot of evidence we won't. We would have found it by now if someone has discovered it in the future.
