Other / Need a new motherboard
« on: July 01, 2014, 08:24:35 pm »
My motherboard and processor both decided to die on me at pretty much the same time so I've had the replace both of them. Thankfully I had a full warranty on both of them. For the processor the store just swapped it for a 4790k which was great. For the motherboard I get to decide what I want since they'll just be giving me in store credit. Currently I'm trying to decide between the Asus z98  Sabertooth Mark 1, ROG Maximus VII Hero, and the  Gigabyte GA-Z97X-UD5H. My priorities are cooling and storage though I like the Dual Ethernet ports on the Asus and Gigabyte ones. I would like to keep it under $220, but can spend more if it's worth it. Any thoughts on motherboard choice, I need it to be z97 or at least Devils Canyon compatible which most of the z87 ones aren't out of the box.

The specs on the rest of the build is:

Math and Science / Interesting Theoretical Math Problems
« on: March 22, 2014, 11:54:33 pm »
What are some really interesting math problems you know of?

One I worked on the other day and neither of my math professors had a quick answer to was: Construct 3 disjoint open sets in R with the same boundary, if it is not possible prove why.
Spoiler For answer:
The intuitive answer that it is not possible because you can't have three disjoint open sets that share a boundary point(this is false at least in R).

The correct proof from this is a proof that in R if a set A is a subset of another closed set B and they share a boundary then the closure of A equals B. With this you can prove that the closure of the first set is equal to both of the other sets. Therefore the other two sets are equal. Two disjoint sets cannot be equal so they cannot exist.
I know this isn't formal, I do have a formal proof, but formatting really doesn't go well on the forums here.

Anyone else have interesting theoretical problems like this?

EDIT: I'm more interested in topics in topology and analysis(recently I've been looking at the cantor like middle-m sets).

Computer Programming / Testing if a rational is in the cantor set
« on: February 03, 2014, 05:05:58 pm »
Is there a fast way to test for membership in the cantor set. My only idea is to test out to some threshold(25 digits or so) and if there are no ones(in ternary) before that to assume it is in the cantor set. This might work, but it is likely to include more rationals than it should(though q will always be under 3^20). Is there a better(preferably fast) way to do this? My code currently spends 97% of it's time in this function(though it is called ~2 million times) and any improvements will give me massive performance boosts.

This is my current code(THRESH is 70 which should be more precision than unsigned long long provides)

Code: [Select]
bool testCantor(unsigned long long p, unsigned long long q)
{
    unsigned long double rem = ((long double)p)/q, div = ((long double)1)/3;
    int test;
    unsigned long long mult = 3;
    for(int i=0; i<THRESH; i++)
    {
        test = rem * mult;
        if(test == 1)
        {
             if(rem > div) return false;
             else return true;
        }
        rem -= test*div;
        mult *= 3;
        div /= 3;
    }
    return true;
}

Now I've made some money from trading doge and christmas and am looking to upgrade it. I got a liquid cooler and an SSD, but I can get more(I have about $400 more). What else would most benefit my computer? I mainly use it for gaming and programming(run a few VM's sometimes). If there are no really great upgrades I'll probably just save the money.

I was  told that a sound card might be a nice addition and this looked like a good one http://pcpartpicker.com/part/creative-labs-sound-card-70sb151000000 I don't know much about them though. One thing I think it might be good to note is that I don't have the best speakers(using ones built into my monitors and a cheap($8) set right now) and my headphones are Logitech G930's which are wireless 7.1 and I believe they have a sound card built into the usb dongle they use. Would it be worth much to add a sound card without buying new headphones? I don't really want to have to buy new headphones right now so I probably won't do it if it doesn't help much(I compose music occasionally though)

What other upgrades might be worthwhile? If I go with the sound card I still have over $200

Computer Usage and Setup Help / Pulsing Power
« on: November 18, 2013, 02:05:10 pm »
I've been using my new desktop for a month or two now and the other day I put it into suspend while I slept. When I got up it was powering on for about half a second every five seconds or so. I rechecked all the wiring and it appears to be good(or at least unchanged) but the problem has persisted and I am unable to turn on the computer. I've tried clearing CMOS to see if I messed up with my overclock(4770k at 4.0ghz), but that didn't seem to change anything. At this point I'm not sure what to do. Any ideas on what is wrong or how to fix it? I have decent warranties on most of the parts so I should be able to get a failed part replaced(would that be PSU or motherboard in this case?)

EDIT: The customer support at MSI suggested I remove my graphics card to see if it would work with onboard video and that(predictably) did nothing.

EDIT2:It worked for a minute while the graphics card was out and nothing was plugged in except the front panel power switch.
As I started plugging other things back in continued to not have problems until I plugged in the power led positive. Then the problem restarted and is not going away. It stopped earlier when I was unplugging things and had moved one cable slightly to the side(not unplugged just moved it away from the processor fan)
I tried redoing everything I did, but the problem is not going away again.

I've been told that it would be better to go with Windows 8, but I haven't had good experiences with it on my laptop. Is the multi monitor support really that much greater?
Otherwise my only real requirement would be running pretty much any game at medium with a minimum of 40fps across all 3 monitors.
What do you guys think could I get better for the same price range?

EDIT: I changed the build a little(removed sound card because cost, upgraded PSU, and moved it to a haswell processor) Also is windows 8 worth it if it is ~$10 more

EDIT2: The 7970 is pretty comparable and is a cheaper card so I switched it out and the motherboard to get the build ~$1500 with an added 64gb SSD

EDIT3: Actually built it now and it is running wonderfully. Tomb Raider at 40fps Ultra across all 3 monitors bezel compensated. I also have a hard drive from a laptop that died that I'll put in there just for extra storage space(and the fact it boots windows 7 off of it) it is only 320gb and 5400rpm though.

Computer Projects and Ideas / MaoBot
« on: July 13, 2013, 09:29:55 pm »
I was recently at a robotics conference where every night a large group of students would play Mao(a card game) together. I've started to really like it so I decided to write an IRC bot to let me play it. It is currently running on efnet and OmniNET in #omnimaga-games and supports OmnomIRC also :D

It currently does just the basics required of a bot and should be ready for release

Here is what it currently does
Code: [Select]
Command List
!join for joining a game
!call <target> <rule> for calling someone on breaking a rule
 -wrong/bad card or out of turn gives someone their card back and gives them another card
 -wrong/bad call reverses the last call by target and gives them a card
!view pm's you with your current hand
!quit has you leave the current game
!play <number> of <suit> plays that card. It is case sensitive
!draw gives you a card
!start creates a new game
!order the order of players by join time
!count <target> tells you how many cards the player has left
!countAll tells you how many cards each person in the game has left
It will also shuffle in a new deck if it starts running out of cards so you can always continue play(hopefully)

Please join, play, have fun, and offer suggestions for further improvement and bug fixes.

code is hosted on github at https://github.com/ruler501/maobot

Computer Projects and Ideas / AssaultCube Reloaded
« on: June 08, 2013, 09:40:54 pm »
I have recently started as a developer on this game called AssaultCube Reloaded(ACR). It is  a fork of AssaultCube which is a fork of the original Cube. So far I haven't done much other than tweak weapon damage/recoil, modify how grenades do damage, and some linux compatibility issues. Recently I have started working on adding in the ability to set custom teams. If anyone finds any bugs please post here or on the forums and the bug tracker, link below. Any issues or suggestions I'm glad to work on them.

Computer Usage and Setup Help / Home Server
« on: January 20, 2013, 09:52:22 pm »
My parents want me to find a way to setup a server in our house that will connect to the network and allow us to back up all of our home computers(about 2tb of data) for under $400. I would also like to be able to use it as a testing webserver, but thats just if I can for the price.
What would you recommend for that price range? The main priorities are keeping the data safe and allowing some revision history and keeping the budget as low as possible. I can build it myself if its just parts and setup.
Thanks in advance for any help

Other / Ubuntu Phone OS
« on: January 04, 2013, 11:07:56 pm »
If you have not already seen Ubuntu the popular linux distribution is now releasing a mobile version. You can find information about it here http://www.ubuntu.com/devices/phone . The main idea that revolutionizes this OS over other mobile OSes is that it seeks to allow people to use a phone as a desktop too if you dock it. It is supposed to transfer over to the standard unity desktop if you plug it into a monitor, mouse, and keyboard. Another thing they have that android(the other linux mobile OS) does not is that they allow easy running of native programs instead of trying to hack it in like android makes you do. They have announced that they are trying to get hardware partners, but I do not believe that they have found any yet. I personally would like to see how this works on a modern phone. If there is a port I'll load it onto my MetroPCS Galaxy SIII. I probably will not keep it, but I think it is at least worth trying.

Math and Science / Unique Representation of Cube Configurations
« on: November 30, 2012, 11:13:54 pm »
In my engineering class our teacher gave us a challenge to draw a sketch of every unique combination of 3,4,5, and 6 cubes. I spent about 30 minutes on that before I realized that I was making lots of duplicates. I wanted to find a way to tell if one would be unique without having to actually make it. I'm not good at rotating it in my head so I wanted something like a formula for uniqueness. I was thinking maybe something like the polynomials, sets, and numbers used to represent knots would work, but I haven't been able to figure out how to do that.

The approaches I have tried are as follows:
Have a set of numbers that just contains how many cubes it touches
Have a set of ordered pairs/trios/etc that are at junctions that say how far it goes in each direction
Have a sets of ordered pairs like above just group them with a number that says what the shortest straight line distance between the junctions are.

I saw that all of these failed. How else could I do this and would a representation allow me to generate all possible cubes without brute forcing it.

Though that doesn't seem to be working. When I try uploading a 10mb avi file it tells me that I need to use a video file. If I take out the condition it says I uploaded a file with no name that is 0kb. I have apache2 and php5. How can I get uploads working where people can only upload files <200mb and that are video files?

I've been trying to learn how to use php and html but I still don't really understand it so it would really help if someone could just explain how to get it set up and what script to use.
I'm hosting it on my server

My moms friend asked me to try and make a good computer for gaming for around $700. This is what I came up with. What do you guys think will it be able to do pretty good or do i need to change it?
