When I type www.amazon.com and press enter, do electronic signals search the entire web. This may sound naive, but does a pulse go to China, Germany and look for it? I know the words are a pointer to a number but I just don't understand the path the electonic car takes to deliver the correct page. Thank you. This has been on my mind for a while.
Can you put video found on DVD on an ipod?
thankyou
Every time I turn my PC on, it gives this message. Is mpdat.exe an important file? Should I be worried it's not there? And how can I get it to stop saying that if not? Cheers -- 212.100.250.212 01:58, 18 October 2006 (UTC)
Hi, I'm trying to put together a program that can resize images using the Lanczos kernel. I already have the code to convert the image to an array of RGB values. However, I'm not sure how to convolve this two-dimensional image with the Lanczos kernel. The article seems to indicate that there exists a two-dimensional formula for kernel. Does anyone know what it would be? Or I might be going about the problem in the wrong way. I would greatly appreciate any advice. Thanks. Austboss 03:57, 18 October 2006 (UTC)
Oh, and another thing. Is this method considered to be the best for resizing images? We don't seem to have an article comparing different algorithms. — Bromskloss 09:50, 18 October 2006 (UTC)
Thanks for the responses, Bromskloss. I've been looking into this for several hours now, and I think I've figured out what I was doing wrong. Just in case anyone cares, I'll explain it here. To resample and resize a two-dimensional (or more, actually) image using a filter like this, you need only apply the one-dimensional version multiple times. That is, first resize one dimension of the image, and then resize the resulting "intermediate" image in the other dimension. Also, we don't have an article comparing them, but there has been extensive work done comparing various sampling algorithms. The Lanczos kernel, while not always the best, is generally considered to be a good choice when both computation time and image quality are considerations. Most image processing software uses this filter as the default. I'll probably try to update the article with this information soon. Austboss 11:40, 18 October 2006 (UTC)
One, whenever I turn on my computer, and I log onto Windows as the owner, and I press ctrl+alt+del to bring up the task manager, a window pops up saying "THE TASK MANAGER HAS BEEN DISABLED BY YOUR ADMINISTRATOR" with a red circle and an X in it. So I looked on Google to see if there were anyways to fix this, and I found that by running REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f in the "run..." in my start menu, it enables me to view my task manager, but only for that current session of windows. If I logout or restart my computer, the task manager becomes disabled again. Please note that I am the only user on this computer, and I am the administrator, so obviously it's an error message that shouldn't come up. My question is, is there a way to permanently enable the task manager so I don't have to run that application to enable it every time I turn on my computer? Thanks.
And then my second question is, I use the task manager to terminate "owner" (as opposed to SYSTEM or LOCAL/NETWORK SERVER) programs that begin at startup. Is there a way to permanently stop these programs from running themselves whenever I turn on my computer? My computer has low specs and if I don't stop those programs immediately at startup then my computer functions very slowly. Thanks for answering my questions. -- Ķĩřβȳ ♥ Ťįɱé Ø 05:12, 18 October 2006 (UTC)
For your first problem try this. For your second question, run regedit and browse to HKCU/Software/Microsoft/Windows/CurrentVersion/Run. These items on the right are startup items, just delete ones you don't need (but dont delete anything that you don't know what it is). Also look in the Startup folder in your start menu (both for you and for the All Users pseudo-profile) -- froth T C 05:28, 18 October 2006 (UTC)
I'm trying to tweek them to get the most powerful searches, fastest downloads, and anything, and everything that fits along these lines, etc.. For example, I want to get as many possiblities in my bittorrent downloads, so do it make it 100% in BitTorrent.BandwidthPercentage. Like, what does that even mean? Help would be greatly appreciated. You can also reply on my talk page. Thanks! Danke! 100110100 10:10, 18 October 2006 (UTC)

I often read terms like transform bin or DFT bin in papers concerning DFT and other transforms.. Can you explain me the meaning? -- Ulisse0 16:44, 18 October 2006 (UTC)
I've read the version article, but I have two questions:
I'm not so interested in the marketing forces behind version numbers, just the general practice.
Thanks! --Sam
Personally, I always thought if you have 10 updates at one level, then you don't have enough levels. I always used a three step version, MAJOR.MINOR.FIX, to avoid this problem. After I had 9 fixes, then I would put out a minor version. After I had 9 minor versions, then I would put out a major version. StuRat 18:00, 18 October 2006 (UTC)
When I use various scanning programs, it scans a folder (apprently hidden) NPROTECT. So what is in there and why is it hidden? - Tutmosis 18:32, 18 October 2006 (UTC)
I live in Corpus Christi, where free wireless is being provided by the city. The problem I have is that there are four wireless access points surrounding me, but all four of them are just a little too far away for me to get access on my laptop with built-in wireless. Is there any way that I can extend my range so I can access them from inside my house? 69.154.49.244 19:43, 18 October 2006 (UTC)
Got a virus or something a while back that screwed around with my registry. Although I removed the virus, the registry stands broken. An issue is that when I hit start, then {my documents, my computer, my network places, my pictures, control panel, my music}, nothing happens. So I navigated to an area in the registry: HKLM/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/StartMenu/StartPanel. I think the virus messed with the entries in there. Specifically, each folder (ControlPanel, MyPics, etc) has three subfolders (Hide, Menu, and Open) that might be malicious. Seeking guidance before I go and delete something.

I'm reasonably handy with web design and CSS, and good at Photoshop too, and I'm sure there's some way to make money out of this but I'm not sure how. I designed a website for a friend's business which netted me a cool £80, but friends with businesses are not thick on the ground and so I need clients. Problem is, I have no idea where to start: I don't have the time or inclination to set up a fully-fledged web design company. Worth1000.com has corporate Photoshop logo contests, where companies pay you money to design a logo for them. Is there a similar thing for web design? Or have you any other ideas? Thanks.
(also, speaking of Worth1000's contests: these seem too good to be true to me. Not that I don't think they're genuine, but it just seems to me that only a small percentage of Photoshoppers are good enough to design acceptably professional corporate logos, otherwise everyone could do it. How easy is it?) Sum0 20:15, 18 October 2006 (UTC)
I recently built a new computer. First build and is going horribly bad.
After finding out the RAM was bad I bought a new pair of sticks and now after getting the system booted randomly the system freezes and the screen jumbles/scatters. Also when I try to reboot the system via the front reset button the system is unresponsive. I am forced to turn off the system via the psu switch. When I turn the switch back on and try to turn the computer on it will not turn on unless i play around witht the motherboards atx connector at which point the system boots but their is no display and the system is unresponsive again. IF i leave turnthe main power off for 20 minutes then the system will boot.
I believe it may be a motherboard problem because my motherboard (asus m2n-e) is riddled with bios problems. I currently have bios 0402 installed and have maxed out the vdimm's to 1.95v. My RAM runs at 1.8v so there is alot of overhead.
Ram timings have been manually set to 4-4-4-8 2T. CPU frquency is at 220 mhz and cpu multiplier is at 11x. In addition the cpu voltage is set to 1.5625 V and is offset by 50mV. These settings have given me longest up time but the system does still crash.
The system specs include:
Amd 4200+ X2, Asus m2n-e, Asus en7600gs (256mb), Kingston valueselect 2X512 pc4200, Enermax noisetakeII 420W, 250 gig WD SATAII hd.
Thanks in advance Rahul.
I just tried another psu. ThermalTake TR2- 430 W. Same problem but now the jumbled screen wasn't as bad. The original display on the monitor wer scattered and the text was readable. Could my problem be that my psu is too weak for the job? The one i just tried is 430W and the last one was 420w.
when you nest in css, for example
body table { width:100% }
where that would make the width of all tables in the body 100%, can you do something like:
#myID table.myClass { ...; } thanks.

I've got a pretty nice-looking LaTeX document, with just a handful of tables and figures. So few, in fact, that it seems really stupid to have the List of Figures on one page and List of Tables on the other. Is there any way to stop them automatically creating a new page?

\renewcommand
to redefine the \tableofcontents
not to include a \clearpage
(or whatever does the page break) at the end. This might be what the original looks like (found in the file book.cls
:\newcommand\tableofcontents{% \if@twocolumn \@restonecoltrue\onecolumn \else \@restonecolfalse \fi \chapter*{\contentsname \@mkboth{% \MakeUppercase\contentsname}{\MakeUppercase\contentsname}}% \@starttoc{toc}% \if@restonecol\twocolumn\fi }
