US Wireless Carriers Shifting To Voice Over LTE

chgros Re:Expose limits as unnecessary? (126 comments)

But the current state of things is that we pay more for data than for voice.

Traffic Optimization: Cyclists Should Roll Past Stop Signs, Pause At Red Lights

chgros Re:Many polite people (490 comments)

I agree.
I wish more cyclists were like that, too. It's really annoying, as a cyclist, to stop at a red light, to be passed (often on the right, and very close) by another, slower cyclist.

Steve Jobs Defied Convention, and Perhaps the Law

What's the difference actually? I'm not an expert in contract law.

450 Million Lines of Code Can't Be Wrong: How Open Source Stacks Up

chgros Re:HIgher defect density indicates BETTER code (209 comments)

while (source[i] != '\0')
{
        dest[i] = source[i];
        i++;
    }

So one error in that code would be 1 defect per five lines or so.

Here's all the code you need, what a better programmer would write:
while (*dest++ = *src++);

Your "better code" is actually not equivalent (the first loop doesn't copy the nul terminator). Even if it was equivalent, I don't think I would necessarily call it "better". This particular piece happens to be fairly idiomatic and many would understand it, but cramming as much semantics in one line as possible is usually not a good idea. I agree that in general less code is better for equivalent behavior, but usually that means better factoring, not putting more code in one line.

USMA: Going the Extra Kilometer For Metrication

chgros Re:Boggle (909 comments)

That definition depends on gravity at the point of measure (I think. I'm not sure what's "a pendulum at 38 degrees"). How is it more a "defined in physical units" than 1/10,000,000 the distance from the equator to the North pole (original definition of the meter), of the mass of a given volume of water (original definition of the kilogram)?

Solid State Quantum Computer Finds 15=3x5 — 48% of the Time

chgros Re:Can someone explain... (262 comments)

Most NPC problems fall into this category.

Actually, by definition, *all* NP-complete problems fall into this category (unless P = NP)

Boeing's X-51 WaveRider Jet Crashes In Mach 6 Attempt

chgros Re:What's the hurry? (190 comments)

Last I heard, jets were going as fast as possible (despite the large increase in fuel consumption from near top speed to top speed) because of the savings in staff costs. So, fuel savings wouldn't necessarily hep that much.

What's To Love About C?

chgros Re:One good reason... (793 comments)

Well, if you can add a field at run-time then by definition you can't check its presence at compile-time.

What's To Love About C?

chgros Re:One good reason... (793 comments)

More importantly, it is runtime-resolved.
I personally would consider this a disadvantage.
I like my type-checking at compile-time thank you.

Nearly Half of American Adults Are Smartphone Owners

chgros Re:Rots your brain (267 comments)

Other than the "convenience" of being able to get at your email, a crutch for a stunted sense of direction, and a safety net for poor before-hand planning
These are all excellent reasons for using a smartphone (and you don't need a stunted sense of direction to find maps useful). Anything after that is bonus.

Are Engineers Natural Libertarians Or Technocrats?

chgros Re:Not sure I'd want an engineer/politician (727 comments)

> besides intercourse
What makes this one more logical than any other, especially since you claim that having children is illogical? I'm curious.
Also, you seem to assume that being logical means maximizing productivity. Personally, my goal in life is not to be the most productive. Entertainment is actually closer to it.

OCaml For the Masses

chgros Re:Another functional programming fan (338 comments)

But don't think that Lisp is always the right language for scripting your text editor (dodges blow from Emacs partisan).
Lisp is functional, but not statically typed. Loses most of the benefit IMO.

Fusion Thrusters For Space Travel

12C -> 4He + 4He + 4He is exothermic. (The reverse reaction is an energy source for stars under some circumstances.)
You meant endothermic then.

Apple AirPlay Private Key Exposed

chgros Re:Open source win (306 comments)

information theory
You probably mean "cryptography". Information theory is related but different.
Anyway, cryptography makes a distinction between "obscure" and "secret". The idea is that good cryptography requires a secret. If something is in your possession (like a program on your disk), it's not secret to you (exception could be made for some secure chips that are designed specifically so that you can't read their secret).
