What is the cheapest way to do something all alarm clocks have: power some leds after a button was pressed for like 5 seconds? Pic related seems to be the way to go, but what capacitors and resistors would I need so it would be powered for 5 seconds after the button being pressed?
>>
What's the shortest you can make this? I'm sure there's a way to make it a single ternary but my brain isn't working today

 var rowExtraClass = (DataFirst ? ((model.Data.Count) % 2 == 0 ? "debug-entry-even" : "debug-entry-odd") : "debug-entry-even");
>>
>>45647046
Just so we're in the same page, you are doing this right?
if (DataFirst)
rowExtraClass="debug-entry-odd";
else
if (isEven(model.Data.Count))
rowExtraClass="debug-entry-even";
else
rowExtraClass="debug-entry-odd";

Looks like the only circumstance in which you set the var to "even" is if both conditions are true. So:
var rowExtraClass = (DataFirst && m.D.C%2==0?) "debug-entry-even" : "debug-entry-odd";
>>
>>45647046
>>45647187
nope i'm wrong
if Data First is true then there's a chance that it's even or odd, else it's definitely even
you are making two decisions so you need two statements (or a compound statement like you had) i think

There's an electric noise coming from my computer but I can't tell what exactly. It doesn't sound like coil whine since all the videos I've heard it in has the pitch varying and this is a constant noise.

It's almost inaudible, but if you try to listen to it you'll hear it and it's annoying.

Any idea what it could be?

I have two network cards one that is for my home computer and the other that is bridged to a vm that hosts my webserver. I am trying to forward port 22 home and port 80 to my VM. My website is functioning fine but ssh will not forward home. My router is only recognizing one IPaddress but two entries of it. If I refresh that page it will display two entries of the other IPaddress and will oscillate each time I refresh.

Hello /g/

The Ram on my system has died and I am looking for a replacement, this is an older system so top tier performance is really not required, I would much rather prefer price over performance so a single 1x4GB is fine.

Specs:

Asus M5A78L-M/USB3
AMD 630 x4 @ 2.8GHz
550w PSU
1TB HDD

I was looking at this but to be honest I am unsure if this will work and if this is a good choice for price/performance:

Corsair CMZ4GX3M1A1600C9


Any help is greatly appreciated

How to fix? Is this a registry thing, maybe?

>>
>>45649819

To answer your question, the 8GPU compute cores are like the same thing on a dedicated GPU. Each core is equivalent to 64 stream processors for a total of 512.

The 860K is just a 7850K with those 8 cores disabled. So unless you were going to crossfire, then they are useless to you.

Unless of course you mean if you could use them for non crossfire computing relating tasks like OpenCL rendering or something, in which case I'm not sure, but that sounds like some advanced wizardry.
