Submission + - Ask Slashdot: Tips on how to ground your computers' case when it is shocking you 1

Walczyk writes: Have you ever had a pc that could slightly shocked you when touching the case or unplugging a cable?

I killed my speakers in such a foolish and avoidable way. My stereo preamp failed so decided to connect my speakers' amplifier directly to my computer; it sounded fine except I needed the pc's volume to be at 8%. It is a high end sound card, and I think it sounded better than before. Unfortunately I noticed that if the RCA cable connecting the sound card to the amplifier was disturbed then it would emit very loud pops of static. Only after both speakers' tweeters stopped working after a very loud buzz did I realize other current was coming across the sound card's metal. I first blamed the cable, then the amplifier but both work fine.

What can I do to reduce this leakage of electricity when I take apart the computer? I am going to replace the stock power supply at least. Is there a way to ground audio cable?

He's amazing artist, and I can't think of another like him. He has such a mastery of light, the sheer feeling of bewilderment his art will impart on you is worth it. It's worth learning about his art, and trying to experience what you can, and it's worth donating to Roden Crater to see it finished. Obviously we all can't do that, maybe he should start a kickstarter :)

Public access websites are different than a corporation's internal network, and should be held to higher security standards due to their visibility and fallout if they do get hacked. After working in IT departments at a few companies I have the feeling that the majority of companies have little to no security prevention, they just expect that nobody will be interesting in hacking their databases. It is so much more profitable to sell data to the Chinese.

I'm dumb, in that a lot of people are already talking the possibility of tachyonic neutrinos. But remember, the existence neutrino oscillations of generation necessitate that at least one neutrino must have non-zero mass. I think the oscillations and these new results will be reconciled as effects of the same (new) physics.

Geez. Look up Tachyons. They are a theoretical massive particle traveling faster than the speed of light which is totally consistent with all theories of relativity. So basically everyone who talks as if it invalidates anything are just speaking talking points they read somewhere. You need to see the speed of light limit is valid for both sides. Relativity posits subluminal particles can never move faster than the speed of light in a vacuum, and superluminal particles can never move slower than the speed of light in a vacuum. Get yo shit straight!

I don't know how you messed up the math when you made that post: when i read the op it didn't look right so i did 100-3.5/365 and the uptime for twitter was 99.990%, similarly for xanga and imeem their uptime (100-1/(6*365)) was 99.999% (nerd fact: i then tried it in units of hours not days and if you round the 4th significant digit 100% is more accurate than 99.999%).
