A pure functional language is one that just relies on recursion with only parameter variables to carry out loops. Sorry , but while that may have some kind of academic aesthetic to various hard core CS types, I really don't see why its that is any better than OO or even procedural style programming especially since both of those paradigms support recursion anyway. To me, pure functional just seems to be a very quick way to obfuscate even the simplest potential solutions to a problem.
Erlang is a functional language first , OO second. Smalltalk was designed to be OO from the ground up. In smalltalk even first class objects such as integers have methods and can be passed messages. Thats taking it too far IMO , but you can't get any more OO than that.
1) OpenGL had an influence on parts of X windows which framebuffer aisde has nothing to do with the linux kernel.
2 & 3) XFS had been pretty much an irrelevance in the linux ecosystem , hardly anyone used it. As for the memory scaling - I think you're overestimating their contribution to the total.
A) Silicon graphics had little influence one way or the other on the progress of Linux (or Windows so the same applies) even when they were a big player.
and
B) Your average home user would not be willing to pay the multi thousand dollar price tag of an SGI system just to have a version of Unix wirth decent graphics at home.
Unfortunately both SGI and to a lesser extent Sun missed the signs that x86 PCs were going to rapidly catch up woth the abilities of their workstations and instead of dropping prices to sane levels continued to carry on business as usual as if it was still 1990. And the end result is what you see.
Its a lot easier to use - 10 years ago if for example you double clicked on an AV link you'd just be met with a "Huh?" prompt from the window manager and would have to go find an app that could read it. Similarly most MS Office file formats were a game of chance with the free software around at the time.
Having said that , there does seem to be a tendancy for distro devs to pack in the the latest stuff into a release simply because its available , rather than going for stablity and interoperability with maybe slightly older versions of software.
We know on earth deserts can form in a few thousand years so why not on Titan? Perhaps that lake is the remenant of something much larger that formed when that part of the moon was far wetter a few thousand years ago?
"The great secret that all old people share is that you really haven't changed," wrote the late novelist Doris Lessing. "Your body changes, but you don't change at all."
I'm sorry to say thats BS. I'm in my 40s now and I'm a rather different person to the arrogant know-it-all teenager I used to be - different attitude to life, different musical tastes , different temperament, a lot more worldy wise etc. And in another 40 years - if i live that long - I'm sure I'll be different to what I am now. Its not just the body that changes , the mind changes too.
Thats great, but most gardeners seem to take the easy way out and just spray everything, use fertlizer and peat. I suppose its another example of the instant gratification that society expects these days.
If the simulation is only partially correct then any results will be worthless if they're supposed to be used in a medical cure as they could be worse than no results at all.
"I personally would never work in the financial sector"
Presumably following this line of ethical reasoning you wouldn't keep your savings in a bank either? After all, they use savers money to gamble on the markets so you're providing them with collateral.
... but we still arn't 100% sure of how neurons work so while simulating them in a computer might be useful for AI I fail to see how it can be at all useful for medical tests.
"The Linux framebuffer is a way to write directly to the video framebuffer"
No , the linux framebuffer is essentially abstract video hardware so the video drivers can be moved into the kernel instead of X windows having to have them. Unfortunately this means every write to the display now has to go via the kernel instead of going direct. X using its own specific video card graphics drivers avoids this and is in consequence a damn sight faster. And the programs I tested were using base Xlib on a raw X server with no window manager running or compositing in sight.
I know nothing about IPMI so sorry if this is a dumb question:
If it doesn't require the CPU or RAM so be on then am I right in assuming that IPMI is some sort of separate system on a chip (or similar) on the same motherboard as the main computer? Or does it wake the main CPU up and use that?
If it is a SoC or a microcontroller with a few extra bits - has anyone hacked it to do more interesting stuff other than just update server parameters?
Previously barring a lot of eye candy that could be turned off , MS did generally get their UI about right. Now with spillover effect from Win8 they seem to have completely lost the plot and this is simply an example of them reloading the gun once more to take aim at whatever is left of their feet.
You got it spot on. One thing you didn't mention was critical mass - once enough people are using a language others will come along and try it (or be forced to use it at work) no matter how good or bad it is and once they're comfortable with it they'll probably carry on using even if there are better alternatives because a learning curve is always more hassle than staying with what you know.
"Aftershave companies are selling SEX APPEAL. That is the actual thing that they're selling."
Oh riiight, of course. So if the girls were on stage pole dancing you wouldn't have a problem with it? After all, they're selling their sex appeal , right?
"As I said (lower in my first comment), the COMPANIES should stop this because it is disrespectful to women, and in particular it's disrespectful to women in tech (those are the women who might want to go to tech trade shows, right?)"
So I guess all the aftershave companies who show guys with ripped abs in tiny shorts are being disrespectful to men?
"ook at my low user ID, I've been here for longer than some of you have been alive."
No one cares. I'm probably the same age as you but I don't go around pointing it out as if it somehow adds extra weight to the argument.
"I am literally white hot angry with whomever did it b"
You'll get over it.
"f you have a daughter, I expect you'll want her to be a geekgrrl. If you want that outcome, you will join me in boycotting booth babes."
Actually if I had a daughter I'd let her do whatever she wanted. Unfortunately you obviously don't realise it but you're just another one of those self righteous prudish males who seem to think that women should only do the jobs YOU approve of. Newsflash pal - its the WOMEN who get to decide whether to do it , not people like you.
I suspect in another century you'd be at the pulpit foaming at the mouth and damning any woman who dared go out with an unmarried man or wear a short skirt or speak before a man gave her permission.

The PC market only boomed because the unix workstation manufacturers saw the consumer and small business market as beneath them. More fool them.
Wrong.

"(Retired IT worker & savings) = FALSE"
Really? I work in IT and I've got plenty of savings. Perhaps you should take basic finance lessons.
Thats great, but most gardeners seem to take the easy way out and just spray everything, use fertlizer and peat. I suppose its another example of the instant gratification that society expects these days.

"it's hard to argue that contemporary projects, like UAVs are justified."
Really? Why? Based on bang for buck and money and lives saved UAV is probably far and away the best value military system of the last 50 years.
Pesticides , herbicides, non renewable peat being used up just to grow pretty ickle flowers that will die within a few months anyway.
Etc.

No , the linux framebuffer is essentially abstract video hardware so the video drivers can be moved into the kernel instead of X windows having to have them. Unfortunately this means every write to the display now has to go via the kernel instead of going direct. X using its own specific video card graphics drivers avoids this and is in consequence a damn sight faster. And the programs I tested were using base Xlib on a raw X server with no window manager running or compositing in sight.
"xhost +"
Sorted.
That would be why X running with framebuffer runs slower than X talking direct to hardware on both of my machines I suppose? (X is an application btw)
"but it was a pain to set up and get it working."
Yup, I mean look at these examples for how devastatingly complicated it it:
"xterm -display [host ip]:[display id]"
or if you're feeling even more l337:
export DISPLAY=[host ip]:[display]
xterm
But I guess if you wet the bed at the thought of having to use a keyboard instead of a mouse then you're pretty screwed.
