Suppose, in 5-bit unsigned integer arithmetic, I wish to compute 13*17/19 (that is, 11). Is there a standard trick for performing such calculations efficiently (in terms both of execution time and code complexity) when no higher primitive word size is available? In particular, I mean a*b/c where the numerator is not representable but the overall result is. (Obviously changing it to a/c*b or a*(b/c) doesn't work for integer arithmetic and yields 0 here.) -- Tardis ( talk) 00:05, 22 June 2010 (UTC)
I have Windows Vista Home Basic and I'd like to place my computer on a setting that provides an audible/visible warning alarm that the battery is low. Please advise. DRosenbach ( Talk | Contribs) 02:12, 22 June 2010 (UTC)
In a Network Interface Card with multiple ports, does each of the ports have its own IP address, or do all of the ports share the same IP address? In addition, do Network Interface Controllers have permanent IP addresses, or are IP addresses assigned (whether statically or dynamically) to Network Interface Controller?

I have used Suse Linux for many years now and want to look around a bit more. I just tried Ubuntu, but that had too many issues. But the amount of distros is just staggering. So can anyone suggest one for me that is to my liking? So what is my liking? Here's a list:
I say I want it to be both keyboard- and gui-oriented. That is a bit of a contradiction, so let me explain. I want it to be gui-based so I get a complete overview of all options without having to know them by heart. And if I have an overview, it makes most sense that I can activate those options in that overview, without having to switch elsewhere (the command line) and then type that in. Alas this is hard to do with a keyboard, so I'll have to compromise there and use the mouse.
Note I said a complete overview. So not loads of sub-sections that show just a few options, where you have to click 'advanced' to get just a few more. I have a big screen and want to use it to the full. And big tables don't scare me, I love them (if they are logically ordered). If I don't understand something that doesn't matter. I'll leave it alone but will have learned that that option exists and in which context. I don't want to be shielded from details I am supposed not to understand (says who?). I may be ignorant but I'm not stupid. :)
Some examples to illustrate what I like:

I'm looking for a freeware program that can automatically do either one of the following things:
1. Sync files from a specific folder on a network drive to a local drive.
2. Backup/upload files from a specific folder on network drive to cloud storage.
Background: I am constantly updating the files on the network drive, but the program I'm using bugs out on occasion and may delete the file I'm working on. I can't work off the local drive because the files need to be available to my coworkers. I would like a automatic backup option that takes the files from a specific folder (the network drive is huge) and puts them somewhere else.
I'm hoping there's a freeware program out there that can do this, or fairly cheap program.
I've already tried SyncToy (not automatic) and DropBox (doesn't work off network drives).

Here's how I understand it. Please correct me where needed. So, the metric kilo, mega, giga prefixes are multiples of 10. But for the longest time, those prefixes were used to describe base2 memory sizes -- even though they were not the same. A "true" megabyte is really 1,024KB, not 1,000KB. As the numbers got larger, there was more of a discrepancy between base10 and base2 numbers (A "true" computer gigabyte is 1,073,742KB, not 1,000,000KB... a difference of over 73MB.)
Computer storage manufacturers measure drive space in kibibytes, but marketing them as kilobytes.. So when a user plugged in a "1 Terabyte" drive, their computer actually reported 976 GB. So the term kibi, mebi, gibi are used to correctly and precisely describe the actual memory a computer sees. So while the metric prefixes are wrong, it's common usage. Man, that's confusing. -- 70.167.58.6 ( talk) 15:41, 22 June 2010 (UTC)
Can anyone please help? I've always read Wiki at work and on my home computer the print is all illegible, small and I cannot read it w/o really squinting hard. It's nealry impossible...totally unclear.
I've reset my display for larger type (I prefer small, crystal clean fonts) but that makes little difference.Is it my system and is there any way I can make your program legible? I've read Wiki for a long time and miss it.
This does seem new. I can't recall it being this way here at home before recently.
Thank you for any help here. I've tried resetting my type sizes/fonts and it makes little difference. Wiki is the only site where this occurs.
Sorry to send it here but I can't read the site well enough to find another place on the Wiki site.
Thanks,

hay, i wand to know the operation behind deletion. usually i delete unwanted files in my system and always keep recycle bin empty.once i noted that a particular software in my system (installed by my brother) help me to retain the deleted files.how it is possible.then Wat is actually happening during deletion. is the same operation take place during cut-past,copy-past? —Preceding unsigned comment added by 117.204.85.120 ( talk) 18:08, 22 June 2010 (UTC)
i wand to prevent a file to be copied from my disc by others (but it should work from disc), is it possible then how?is it possible to copy it later by me,how? —Preceding unsigned comment added by 117.204.85.120 ( talk) 18:13, 22 June 2010 (UTC)
I have two old computers sitting in my basement locker—they have been for a few years. One’s on a pre-Windows XP, whereas another doesn’t seem to have an OS at all. I want to give them to someone who knows even less about computers than I, and both of us are poor (though I have my own computer (Windows XP with Office 2003)); and I feel free to experiment with these two computers.
First, can I and how do I create “partitions” for MS OS’s and Linux?
Second. Presuming that older is generally cheaper, how much would it cost to get, say a Windows XP, 2000, 98, 97, even 95?
Third, as I’ve never done this, are these discs re-usable? Could I take, say a Windows XP and upload it on +10 computers? If so, could I do the same with, say Office 2003 Professional?
Fourth, let’s say even a used Windows XP and/or Office 2003 Pro was too rich for my blood, and I decided on, say, Windows 95, what are the latest versions of WORD, EXCEL, and POWERPOINT, and PAINT could I use?
Fifth, how do I get such computers to take an OpenOffice? Could I get them on the earlier Windows, and/or I would be better to have them on the latest Linux versions?
Sixth, what good free painting/pics and player software would you recommend? Could Ogg Vorbis be installed in earlier Windows, or should I have it on Linux?
Seventh, as I’m too poor for even internet connections (I’m using an employment centre computer to post this) how would I download this on another computer (say internet café one) onto a USB, CD-ROM, or DVD-Rom, and then install it on these computers.
Thanks for the help and time.
:-)

In the Babylon translation-software, the user can add Wikipedia as one of the online dictionaries. It is possible to download Wikipedia for offline use, through this link: http://download.wikimedia.org/enwiki/20100130/enwiki-20100130-pages-articles.xml.bz2 But is it possible to do one of the following: (1) Get an offline version of Wikipedia for Babylon? (2) Convert the above XML-file to a BGL file?

I'm trying to mirror a specific part of a website, not the whole website. Through searching, trial and error and hours of wasted time I've come up with the following:
wget -mk -X */images/ -np http://example.com/pages
However, this only downloads the html files in the directory "/pages/", and not any of the other resources that are displayed on the pages. I want it to download the css files (located at http://example.com/css/) and the thumbnails (located at http://example.com/thumbs/). What do I need to do to make wget do that?
