WHY THE HECK YOU DOING THA... and now you work... WTF?
 
I swear to God you better work!


I am sure most of us have experienced something like this. Although computers can be weird and wonderful things, they can just be weird at times. I have worked with computers for a long time and most days, something stupid will happen, even if it is a small thing.

An example of this would be your computer doesn't let you delete a file, saying it is being used and then, two seconds later, you can delete it, but you haven't even been using the file.

Share your lol worthy computer problems and random experiences with the stupider side of the technology world.

I haven;t had anything other than the "Can't eject drive because it's in use" myself, though a relaunch of Finder fixes that easy enough. However someone down the hall just had a moment like that. They couldn't load anything in EI so they went through the Windows troubleshooter which concluded that the router had an invalid IP, though at the conclusion of the diagnostic EI began functioning normally again.

The other day, my sis had trouble working a blender. She went online, looked up the model, and found that others said to whack the thing. Hard. So she did. It worked.

my win xp wouldnt boot it was getting frozen at the win xp home edition loading and a week after without touching her she booted perfcetly and was even faster than before XD.

I think Microsoft's motto is just, 'Hit it hard' because when a 360 doesn't work, people just hit them and they work! XD

One time, I tried dual booting Ubuntu and Vista, and after I got the boot up and working perfectly, I tried to install the Linux driver for my graphics card so that I could turn on enhanced graphical settings.

Next thing I know I have one dead Linux installation and Vista's UI is messed up. I spent a good 5 hours straight fixing that thing. And not because I didn't know how either. It just took that dang long.

Talk about WTH moments.

Well, I was writing this program, and it needed to solve some equations.
Somehow, a double precision variable x, which was equal to zero, satisfied x < 0
How can something be equal to zero and still be less than zero?
Further when I made it output, -1*x, it always outputted -0.0.

I still haven't understood why?

Christ, don't get me started on stupid programming problems! XD

For some weird reason, I was working in C++ and all I wanted this part of the program to do was to print to the console. 'Cout' right? Wrong. No matter what I did it wouldn't work.
I close down the program, re-opened it and it worked! FFFFFFFFFFF! XD

That is weird, I know that feeling...

Can't figure out why it doesn't work, you fiddle around with it for a while, run it and it continues not to work. Then you shut it off and fume for a while, return to it after you've cooled off and it mysteriously works without you having done anything to it.

This is why the IT Crowd is amazing.

'Hello, IT. Have you tried turning it off and on again?"

Golden! XD

My laptop is oold...as in, I got it for Christmas 2004, and although I still use it regularly, every couple of months, it decides to not work at all for a couple of days. I press the power button, wait a couple of seconds, and it shuts off by itself, with the "low battery" light blinking. Now I know when my battery is dead because I keep it plugged in 90% of the time I use it, so I knew that that dead battery indicator was bull.

The first time it did this, I genuinely freaked out and tried calling everyone I knew to see what they could tell me, until I tried turning it on two days later only to see it working perfectly fine. This odd episode has repeated itself twice since the initial one, and I just stopped worrying about and just tale a mental note to not use the damn thing for the next couple of days. >_>

There's a slight possibility that the battery is actually to blame for that. On occasion, a laptop battery can actually stop either the whole laptop, or just certain parts, from working. I would say try to run it without the battery until you think it's about the time that the issue would start arising. If it doesn't do it, then you have your answer.

Of course, there's also the possibility of it just being the laptop due to it's age. The hard drive could be failing, but without having it in front of me, I couldn't really say.

Never really had this happen, apple seems to be pretty good about keeping glitches and stuff to a minimum.

However when I was fiddling with my audio drivers on my fresh windows 7 install, I had this happen.

Drivers have a tendency to be that way in any version of Windows.

Mhmm, it worked fine for the first time I had it booted, then I booted the next day and it said I didn't have a sound card installed at all. So I ended up uninstalling all the drivers and reinstalling them.

Drivers are the biggest pain when doing general IT support. Even moreso than dead hardware, in my opinion.

Captain Fabio July 21st, 2010 3:35 PM

I wish drivers didn't exist. They are such a pain at times when building computers. Or when you are updating something.

They work fine normally, but you will always get that odd one that just doesn't seem to play ball.

I can usually figure out why something's going wrong unless it's related to hardware failure. That's where I tend to get stumped.

Hardware is one of my specialities! XD

I can normally work it out, but it still makes me go... WTF at times.

mr. ck July 22nd, 2010 7:55 AM

I can solve everybody else's problems in a few seconds... But to solve problems with my computer, it takes a few hours -_-

Well I was solving a problem at one of those online judges, my answer wasn't accepted because of an epsilon error in floats.

I hate floats/doubles with a passion!

You'll be happy to know, then, that floats and the like should be avoided, especially when doing precision tasks. Computers only estimate floating point precision, and with prolonged precision tasks will start to become inaccurate. It's much better to use integer precision and division, it's much more accurate.

locoroco July 22nd, 2010 12:14 PM

like my hd audio driver its a new comp (no problems the initial 4 or 5 weeks) then i was getting blue screen each time i tried booting my game it said viahduua.sys and im like thats my audio driver i had to uninstall and install again now no blue screens yay!!

Drivers pain in the a**. Blue screens make me want to commit suicide.

I know... But what can you do when you need to handle fractional / decimal data, at most maybe use double?

Having had an epic Driver fail that required an absolute minimum of 5 hours of downtime while the computer fixes itself I can't help but agree.

As long as you're working with rational numbers or something that can be written as an expression, you can use integer data and division or other operations to represent whatever decimal or fraction you want.

This is a rather contrived solution, but let's say you have a number like 3.2 that you want to work with but don't want to use floating point for accuracy reasons. Rather than
Code:

float importantNumber = 3.2;


perhaps you could do
Code:

int importantNumber[2] = {32, -1};


where the first number is an integer representation and the second is the power of ten you need to multiply the first by to get your floating point number. There's probably a better way to do it, but even this way is better than using floats if you need accuracy. If you needed to do a calculation using importantNumber, you could do (importantNumber[0] * 10^(importantNumber[1])) and then whatever calculation you need to do, and then store the result the same way.

It's usually not important for smaller scale applications, but in applications where accuracy is absolutely necessary, you have to do something like this, as floating point representations lose accuracy relatively fast (this includes doubles, as they're still representing a number as a floating point rather than an integer).
