What is flicker? How this can be reduced? —Preceding unsigned comment added by Ajit.abhishek ( talk • contribs) 04:00, 1 June 2010 (UTC)
My Windows 7 desktop computer just crashed with no warning whatsoever, giving me a "disk boot failure - insert system disk and press enter" message. So, after several attempts of accessing my system drive with no success, I decided to try booting from a Ubuntu Live CD (v. 10.04 "Lucid Lynx", if that matters). I successfully burned the .iso to a disc and tested it under Parallels on my MacBook, but I can't boot into Linux with it on my desktop. It spends a long time telling me my SATA drive is misclassified, then it hangs for several minutes at a line that has syscall_call+0x7/0xb on it before going to a black screen, whereupon it is either hanging up completely or taking over 45 minutes to do whatever it is it's doing.
I've tried messing with the boot parameters according to this page, with the same result.
Here are my system specs:

My neice has a PC, a Dell Dimension desktop PC around 5 years old, with Windows XP SP3. After much hassle getting a stable connection to the internet using the wireless access point in a distant corner of the house, earlier this year I installed a Belkin N Wireless USB adapter which is connected to one of the USB ports on the PC, and now the connection is pretty reliable. Like many teenagers, she is heavily into social networking so has installed several messaging apps and Skype, and has recently got herself a webcam so she can hold video chats with her friends. Recently, there has been some problems when she connects a USB flash drive or a digital camera, the PC reports that the device has "malfunctioned". After a lengthy investigation last weekend, including a full reinstall of Windows, I have at least managed to find out something about the problem.
While the PC appears to have many USB controllers listed in the device manager, only one is a USB 2 controller. The wireless adapter is always connected to this controller. When the USB flash drive or a digital camera is connected to any physical USB port, it is also connected to this same USB 2 controller but draws 0 mA (the wireless adapter seems to draw all 500 mA available under USB 2). I strongly suspect the reason the PC reports the devices have "malfunctioned" is a lack of power, and this is reinforced because if I disconnect the wireless adapter, the other USB devices now magcally work again.
My investigation has led to a number of questions: Why does the PC allocate the other devices to the only USB 2 controller rather than one of the 3 unused USB 1 controllers? Is there a way I can reduce the power consumption of the wireless adapter? Would connecting an external, powered USB hub solve the power problems? Would buying a USB 2 PCI card, make additional USB 2 controllers available so that the PC can allocate the other devices there instead? Astronaut ( talk) 13:20, 1 June 2010 (UTC)
Is there an archive of the in the news section (right side of homepage)? I'd like to make a screen shot of a particular news event last week (maybe 2 weeks ago). Cheers! Aaadddaaammm ( talk) 13:54, 1 June 2010 (UTC)
Hi, I'm trying to understand the term "socially engineered malware". I found this definition, but I still don't get it. What do the words "socially engineered" have to do with anything? Anyone any idea? —Preceding unsigned comment added by 86.185.76.171 ( talk) 16:53, 1 June 2010 (UTC)
I need a program that can monitor rss feeds every few mins and alert me if any contents in the feed match a specific keyword. I'm currently experiment with Thunderbird which is working quite well for just viewing feeds, but I want it to be able to alert me for specific keywords. Anyone know how this can be done, or better programs that might do this? Thanks 82.44.55.254 ( talk) 19:06, 1 June 2010 (UTC)
In excel you can insert a hyperlink into a cell, so that you have an visible anchor and a hyperlink value associated with the cell; and if you click on the anchor, you get taken to the hyperlinked site. So far so good. I have a spreadsheet, it has one column of hyperlinks. I want to extract the hyperlink value, amend it, and insert it as a hyperlink in cells in a second column.
If you want to extract the hyperlink value from acell, it seems you need a custom function such as [9] or [10].
What counterpart function would I need in order to set a hyperlink value around anchors in my second column? thanks -- Tagishsimon (talk) 22:32, 1 June 2010 (UTC)
