« on: December 13, 2013, 12:10:07 pm »

Remember, tonight at midnight (GMT -5) the contest public vote (see here) will end and contest results will be announced.

So far, very few people have actually participated in the voting, so, if you want to have a say in who wins, you'd better act quickly!

Thanks to everyone who participated this year, and may the best programs win!

Math and Science / Re: .9 repeating equals 1?
« on: December 11, 2013, 03:37:30 pm »
@Shmibs: No, I haven't taken calculus. A decimal can extend as far as it wants in one direction, but that still will not make it equal to one from what I can see.
that's true. no matter how many 9s you care to add to the end, you will still have a finite number of them. adding 9s to the end can never help you to reach infinitely many 9s any more than it can help you to reach 1. thus, both 1 and .9 repeating are greater than any number you can reach by simply adding more and more 9s. as .9 repeating is also, obviously, not greater than 1, the two must be equal.

>inb4 that's not exactly true from fish :P

I've had this argument with a friend. To me, a decimal number is still just that, a decimal. Nothing other than 1 can equal 1. If anything, the proof only suggests to me not that .99999 repeating equals 1, but that instead that the decimal system is a flawed way to represent partial numbers.

have you ever taken calculus? that these two things ARE equal is essential to the fundamental theorem, and, thus, most modern mathematics.
think of it this way:
.9 is close to 1, but does not equal it, .99 is closer, and, every time you add another 9, the gap between the two grows even smaller. if you add infinitely many 9s on the end, then, the gap between the two numbers will be infinitely small. an infinitely small gap is not a gap at all, and, thus, the two are equal. take a look at the concepts of limits and convergence.

EDIT: i think where people are getting tripped up is the concept of infinity.

The explanation I have  heard is that it approaches one without reaching it, like an asymptote on a graph, it will get infinitely close, but cannot equal the value of the asymptote.
I agree.

My math teacher has this picture on a shirt  :P
"infinity" is not a number; it's a concept. if something is "infinitely x", then it is as x as something can possibly be. if two things are "infinitely similar to one another", they are as similar as it is possible to be. the most similar two things can be to one another is to match one another in every single regard, so two things that are infinitely similar are the same thing. likewise, if something is "infinitely close to another thing", the two occupy the same space. a decimal place followed by infinitely many 9s, thus, equals one, e(-infinity) = 0, and so on.

if you have the data in hex then that's all you need. just stick it directly into your program, assign it a pointer, and then, during runtime, copy it to the screen buffer and update the display.

That's the problem though. ATIs performance last I checked was horrible. And since AMD opened up their GPU documentation their non-free driver got to the point were it's not worth trying.

ATI/AMD performance compared to intel graphics better than to nvidia graphics.

I'm a Linux user since more than 15 years and have been using nvidia most of the time but went through matrox, s3, intel, via, and ati, too. I really wanted to switch to a more free option several times and I did try. It just was never worth the performance loss.

So what from a user perspective are the problems with nvidia graphics day to day? Of course the drivers are non-free, unless you use nouveau but then you are better off with AMD. So let's say you are fine with running nvidias non-free drivers - what problems will arise?

There is no kms and it doesn't work to use framebuffer drivers together with the nvidia driver. So no high resolution text mode.
Switching between X and Text virtual consoles is flakey. Sometimes you loose text virtual console visibility. On a Desktop however 99.9% of the time you stay in X. On very rare occasions This switching left me with no graphics whatsoever and only a reboot helped.
RANDR support is there. Since this happened multi-monitor support is decent using the distributions own configuration tools. no need to change your Xorg.conf file.

Sometimes after a kernel update or a graphics driver update there is a mismatch of driver versions and X won't start. DKMS and other infrastructure by the distributions mostly takes care of that.

On the other hand when it works, and it usually does, the experience is unmatched. You get reliable and fast graphics with opengl just working. There are apis and api support for video playback acceleration and cuda. And there is infrastructure to actually use it.

In my opinion not using nvidia graphics for a Linux desktop is a very bad idea. Unless you value the freedom of your systems software over it working.

Edit: I did some more reading about the non-free amd/ati drivers. Apparantly the situation improved a lot. So non-free AMD/ATI can now actually be compared to non-free NVIDIA. That being said I'd have to try myself to actually see wether installing the ATI drivers has become something that can be done without hours of cursing nowadays. The ratio of nvidia/fglrx problems I've seen strongly suggests prefering nvidia.

i have a modern nvidia card and nouveau handles my set up just fine doing the sorts of things sorunome said he'd be doing. i'd much rather have an ATI card, though, because of the better performance and less ambiguity about the future. what things are you doing that *require* the proprietary drivers' speed?

if you have a heavy wallet then go for a mac
it is similar in context with linux---------------> both are based on unix
multi display and everything is there
except for dvd drive you have a separate one for that
ew, you'd have to brainwash me for me even thinking about that, sorry :P


Anyways, out of your posts it seems as if AMD is not that good at all.....(lol, i have an AMD cpu in my lappy)

Also, graphic card, yeah, i heard about nvidia and linux......so i guess no GeForce card. Any suggestions? (other than saying, hm, decent because i don't know what the hay to pay attention for to get 'decent' GPUs)

with what you're saying, i honestly think and ATI card will be fine. if you were going with just one screen, i'd even say to leave out the card entirely and just use high-end intel graphics.

EDIT: for specific ATI cards, i don't know much; maybe you could ask Eeems?

So yeah, I want to get a desktop.
But the thing is: i have like no idea what to look for. What I want to do with it is here:
  • Linux
  • at least two monitors
  • programming
  • finally be able to watch full hd videos without the acting up like i have atm on my lappy
  • I guess USB 3.0 would be cool
  • Run emulations without a problem or much lag (like virtualbox or a virtual androis device or something from that area (I hope it'll be able to run Wabbitemu D:))
  • A second monitor (already have one)
  • Keyboard
  • I guess a blu-ray drive would be cool but dvd is just fine (as long as i can burn dvds)
  • SSD to boot quicker + start applications quicker
  • At least 1TB hdd (or are SSDs so big and long-living by now that i could go full on ssd?)
Yep, no windows needed ;)

So, I wouldn't get anything before christmas now as i'm putting some money for this on my wishlist.

Any ideas/what I whould look for/should i buil on my own?

Thanks for any help :)

Definitely build your own. MUCH cheaper.
depending on how much money you have you can get certain parts for certain things.

You will need/want/what I suggest for the core components.

PSU - atleast 600w. but 700w+ is pretty good to have too.
Graphics Card (you want a good one) - GeForce GTX Series's I prefer the GTX 760 (getting that soon, brother has it)
Processor - INTEL (NOT AMD, because AMD is good for cheap processors and if you are going cheap they are fine, but intel is sturdy it will last and there is a slight difference between them that make me like intel better, cant remember what though) Quad-Core processor of atleast 3.00 GHz
Motherboard - anything that is compatible with all your parts, doesn't need to be too great.
RAM - If you don't really care or it doesn't matter than do 4 gb if you need a little extra then 6 is good. you probably wont need 8 or 16 for a couple years so don't bother.

I'm not a hardware or even software for that matter genius so don't credit me for my likes and dislikes. I'm just trying to help out :P.
If your price range is smaller than this that's fine. You can always get lesser parts but remember your GPU and CPU REALLY matter on the computers performance.

And don't forget you can always download more RAM. :P

AMD has just been cranking up their clock speeds and stacking on more cores to increase their speeds. Intel, on the other hand, has been optimising the crap out of everything, meaning that they are *much* better in terms of power consumption, lifespan, and overall performance (from 8 to 16 flops per cycle with the move to haswell =D). also, like i said above, one should stay away from nvidia when using linux. they're under the sway of wondows to a much greater degree, and nouveau is not very usable.

^truth. since he's not going to be using NTFS, though, it's not a big issue either way.

as for advice. get a haswell processor and an amd graphics card. when looking for haswell, don't discount xeon in favour of i5s either. the biggest differences between the latter and the former are going to be a lack of new integrated graphics, which you won't need because of your discreet card, overclocking, which you won't need for your purposes either and will be better without because power consumption and lifespan, and 25% more L3 cache. as for the graphics card, you don't need screaming performance there either, so AMD will suit your needs much better because you can stick with the open-source drivers and not have to worry about nvidia removing support for things from their linux drivers to appease windows like they have been.
