Ask Slashdot: Handling Patented IP In a Job Interview?

loufoque Re:Your patents are already invalid (224 comments)

Yet another proof that the US patent system is a joke.
It doesn't work like that in the EU.

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).

As usual, the only option to be able to run software decently is to pirate it.
They won't even sell the damn thing, there is no other choice.

The Physics of Space Battles

loufoque Re: It seems to me... (470 comments)

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?

Ask Slashdot: Swift Or Objective-C As New iOS Developer's 1st Language?

loufoque Re:Obj-C (316 comments)

If you choose to restrict yourself to a subset of C++ where you can't use any nice features, then sure, C++ is the same as C.
But that's not what C++ is.

loufoque Why didn't they seek protection? (41 comments)

Why didn't they hide in that kind of shed or under the rocks next to it instead of going in the middle of an open area?
If they wanted to leave, they should have made a better effort and walked much faster than this instead of pausing to take pictures and discuss it between them.

So basically you're complaining because you wrote bad code that only worked due to Visual Studio not following standards and that on top of that you don't know how to read template error messages?
