There's No Such Thing As a General-Purpose Processor

loufoque Re:Efficiency (181 comments)

Most processors require less than 100W.
It's the peripherals that take a lot of power.

Space Tourism Isn't Worth Dying For

loufoque What is this "opinion piece"? (594 comments)

Since when does slashdot publishes some random guy's opinion?
Who gives a fuck if some nutbag likes to proclaim he knows whether the death of someone else was worth it?

I'd rather have news instead.

The Airplane of the Future May Not Have Windows

loufoque Natural light (286 comments)

So I guess that means window-less airplanes won't have any natural light.
This is more of a problem than lack of a view.

Staying 20 hours seated in a plane, waiting, is painful enough as it is, lack of natural light only makes it worse.
Remember that some people (me included) just cannot sleep during a flight.

Jedi-ism Becomes a Serious Religion

loufoque Re: Spiritual Needs (268 comments)

Social constructs that go beyond a single person's individuality are real; be them beliefs, philosophies or values.
Humans are social animals, and it is usually accepted that narcissistic individualism, which goes against this, makes it harder to reach happiness.

Jedi-ism Becomes a Serious Religion

loufoque Re: Spiritual Needs (268 comments)

If you believe that wanting to be part of something greater is juvenile, then I'm afraid you're being delusional and lack self-reflection.
My guess is that you're insecure about your own maturity, which in its itself is more juvenile that the natural human trait you're trying to deride.

Yet another proof that the US patent system is a joke.

Ask Slashdot: Handling Patented IP In a Job Interview?

loufoque Your patents are already invalid (224 comments)

If you mentioned your patents on your resume before the long and tedious process of patenting is finished, your patents are already invalid anyway.

Where Intel Processors Fail At Math (Again)

loufoque Re:Not news (239 comments)

It's commonly used by everyone using "long double" instead of "double" in their x86 code.

long double isn't even supported by all compilers that run on x86-64 (most notably MSVC++), and of course it's specific to those processors. With other processors, long double can mean something else entirely.
Anyone serious about floating point only uses the IEEE754 formats, and for scientific computing the only one used is double precision, though single precision is also popular as a way to get an estimate on which you can apply iterative refinement.

For example, if you want to write a function that calculates sqrt (x^2 + y^2) for double precision x and y, that's very very hard to get right using double precision only, but using long double in the calculation and rounding to double makes it trivial.

Just use a library that does it correctly. The function is called 'hypot'.
Using long double just makes it slow and non-portable.

Where Intel Processors Fail At Math (Again)

loufoque Not news (239 comments)

First, it's an x87 instruction. This unit has been deprecated for a decade.
Second, It was never meant to produce correct rounding for extended precision, and never claimed to. The documentation has always clearly stated 1 ULP of precision.

Apparently, some newbie doesn't understand what this means, and somehow it's a thing.

Where Intel Processors Fail At Math (Again)

loufoque Re:Exact mathematical value isn't the ideal (239 comments)

IEEE754, however, does require the standard C 'sin' function to be correctly rounded (i.e. as exact as it can be given the limited amount of bits).

The Physics of Space Battles

2. Why would a weapons grade laser have great output power but the mirrors not similarly improve?

You do realize weapons-grade laser at not science fiction, and actually exist and are in use in the military?
