the more we learn about pluto, the more I think the probe sould have had a detachable orbiter to be left around it I imagine that would have complicated things a lot on its design phase, but now we'll have to wait more than a decade to do it, if it ever comes to pass
well you can always make a class that encapsulates a number type and give it a default number when it approaches zero, like a very very tiny epsilon, but yeah there are systems where even that is not actually a choice, like some small microprocessors with minimun language support
someone said intel made a chip that could finish an infinite loop in 5 minutes, I don't don't think it would be long before they make one that divides by zero and gives you a meaningful result
Division by zero has no meaning as a direct computation and will most of the time cause an exception.
Whatever factor is being divided, it must have a special case when the divisor equals zero.
Like for example:
X / (Y == 0.0f ? 1.0f : Y)
X / (Y == 0.0f ? X : Y)
It will always depend on the factors being computed, their meaning, and the context in which they are being computed.
A system wide default value would remove that nice exception and then you will have to check by hand every division looking for some 'unknown bug'.
In any case, you DO have (at least in windows) a way of setting your own exception handlers and just do nothing when the exception is raised, although you lose your current execution context, but hey, if you have to ask...
the thing is that if you leave the solar sail orbiting the sun for enough time, it might be theoretically possible for it to achieve near light speed velocity, I haven't done any calculations and so it's almost whishful thinking, but at 10% c it would arrive in just 40 years
would be nice if everything works, when all the tests are done, to put the sail in a continuos orbit around the sun and get as much speed as possible and then send it to alpha centauri and let it take some pictures from there
unistalled kubuntu-desktop 20 minutes after the installation, expent 6 hours trying to figure out how to recover my home folder from the massive screw up that kde caused inside it, call me again in 10 years and I might give it another try at kde, god I love gnome, and could the people from kde give me back those lost hours of my life please??
Dont get me wrong, I *love* gnome, those guys are doing a terrific job, but I'm going to install kubuntu-desktop, let's see what all the fuzz is all about. And also because I can, I've got a little time to spare, maybe I'll stick to KDE, who knows.
and they do it by throttling down transfers not ascribed to their 'new service', that is stealing bandwidth from everybody else, at least when they are running at full capacity again, they will have no choice but to upgrade their infrastructure so some people can start to enjoy the speed japanese folks got for a base broadband connection plan a few years ago
this is not the first time it has happened, hotmail had a rule where if you didn't log in for a month (not sure about the real timespan) they would erase all your mails, they did that to me
i lose years of stuff, hundreds of mails i was keeping there, a shame really, a few months later gmail started giving email accounts for free, and the GiB email free storage race started, i have never come to trust hotmail ever again, they WILL fuck you up if given the chance, why? because those are their servers, their computers not yours, it's not your data, for them the hard drives could be empty for all they care, if you have a problem with that do whatever you want, but start by waving goodbye to your precious bits first
the cloud is a nice feature once you understand you cannot trust your provider and that you should make a backup copy of your data as soon as possible out of the cloud
Amazon dosn't exists anymore for me, so i think i'll pass, thank you very much. A shame i was looking forward to some nice book about the new blender version.

I didn't expect some kind of Spanish inquisition.
nobody expects the spanish inquisition
Helium-3, lets mine the moon
oh yeah, all those inlines unaligned, jokes aside it looks larger at 10pt
...does it feel like another deja-vú

lets all use libvpx and be done with it
of course trying to make it with new horizon's current trajectory would probably be impossible
I never said that

the end of ram maybe, not the other way around

What could possibly go wrong.
indeed, this might become the most sought after vulnerability, the holy grail of hacking, or even a new sport: cpu kill drive by
instead of making a cpu with a decent integrated gpu, intel is giving us the possibility of killing it without even having to open the computer case
this is the first thing i thought upon reading the article :)
It's doing just fine, thank you very much. http://mariadb.org/
meet me at sidorovich's place at 18:00 and we'll talk about prices...

a cover of spam...brilliant :), with fraud for me too please. o/
COBOL is like The Walking Dead of the programming languages right now.
