whats a good free thing to rip youtube vids —Preceding unsigned comment added by Tom12350 ( talk • contribs) 06:37, 26 April 2010 (UTC)
Check these out. BTW, the question above was asked by Tom12350 ( talk). 24.189.90.68 ( talk) 09:03, 26 April 2010 (UTC)
I'm using a bluetooth earpiece headset with skype, but I'm having troubles. My dongle is by a (Japanese?) company called PCi (BT-MicroEDR2X) and the headset is a Logicet LBT somethingorother, and pairing works and I can use it with skype, but if I turn off the headset and turn it back on, it doesn't work anymore, even though it says it should be. If I delete the device, repair and reboot it, it works again, but every time I turn it off and on again it stops working. I'm a bit new to bluetooth, does this happen a lot? 210.254.117.185 ( talk) 12:05, 26 April 2010 (UTC)
In php, what might "$line[$j]" do? 82.43.89.71 ( talk) 14:54, 26 April 2010 (UTC)
Hi, when I type an edit description in the bar in WP it shows up past edit descriptions that I have entered. How can I remove these? I hope you understand my question, I don't think I worded it very well :D Chevymontecarlo. 17:19, 26 April 2010 (UTC)
My work place blocks many websites from access. Is there a way I can connect to my home computer from work, and use its internet which is not restricted? I am very uninformed with computers, could there be a simple program that is not complicated? —Preceding unsigned comment added by 140.121.130.67 ( talk) 17:20, 26 April 2010 (UTC)
In windows, how can I start a program (say for example notepad.exe) without any visible window showing up, so that it can only be seen in task manager? 82.43.89.71 ( talk) 17:45, 26 April 2010 (UTC)
Run, name-of-program-you-want-to-run.exe,, Hide
I tried but it just loads the program as normal. 82.43.89.71 ( talk) 21:16, 26 April 2010 (UTC)
if i were ask to write the sort note on the following:- 1. Quick Sort 2. Shell sort what will be the answer of this quetion? —Preceding unsigned comment added by 41.190.2.158 ( talk) 19:15, 26 April 2010 (UTC)
Our article on /dev/random says that on Linux it relies on network traffic to provide the entropy on routers, so I'm assuming that's also the case for servers that don't have local input devices, or where the local input devices are rarely used. If so, how can we be sure an adversary with a botnet won't generate fake traffic that appears to have more entropy than it actually has, in order to help attack the RNG? Even if it doesn't make the RNG completely predictable, even partial predictability would be very helpful e.g. for cheating at online poker. Neon Merlin 19:29, 26 April 2010 (UTC)

82.43 made an assertion above about limited-rights user accounts that made me think: Does anybody know of a survey that makes any conclusions about how many computers in the world are used by people who utilize accounts without admin rights? Phrased another way, at any given moment, out of all the PCs worldwide that have users sitting at them typing and mousing away, what percentage of them are logged in with admin rights?

It has been a while since I lost Internet access for a significant period of time, and yet even when I did not have the Internet at the time I turned it on, my computer seemed to know what time it is when first turned on, even though I always turn it off when not using it.
