Question - what is the typical limit in Frames Per Second (or fractions of a second) of human visual recognition on a conscious level?
Background - trying to do an experiment in subliminal messages using home edited videos. Microsoft Movie Maker 2 appears to edit only at 7 FPS. I have found that when a frame is 1/7th of second, it is clearly visible to the conscious mind. I have scoured articles on how fast the image needs to be (including Wikipedia article on subliminal messages), but cannot find answer to above question. When shopping for a replacement consumer software package that allows editing in more detail, how many frames per second do I need to edit so that, when I insert the subliminal message frame, most of the viewers will not consciously perceive it?
For extra credit, any ideas on consumer software packages that would allow such editing?
Thank you in advance.

Is it possible for websites to detect whether the browser is using ad blockers? And if the browser is using ad blockers, is it possible for that website to say a message saying ' you are using ad blockers; you cannot see this page' or something like that. Is this possible or is it ot possible for the website to do this? I would also like to know how many percentage of world Internet users block graphical ads in percent
I'm taking a college course right now that doesn't have a textbook; instead, everyone has to print out a bunch of readings for every class. It's taking a toll on my black print cartridge. For Word documents I don't need to turn in, I change the font to a different color (say, blue) because I rarely if ever print anything that needs color. Is there a way to print black and white PDFs, which most of the readings I have to print are, in another color like I do for my Word documents? Thanks. --Maxamegalon2000 17:17, 14 October 2006 (UTC)
What's the best way to send a large file (~100-500MB) over the internet if you don't have access to a reliable server with that much space? The tech-saavy could set up an ftp/http server on their home computer, configure the hardware firewall, and send a link. Most people aren't going to be able to do this, however. What are the other options? Sending the file through AIM? Is there some good free third-party server for this sort of thing-- an Imageshack for half-gig files, for example? --Alecmconroy 19:34, 14 October 2006 (UTC)

[edit] Revert graphics settings
Is there a way I can revert back to my graphic settings from a previous date in Windows XP?207.200.116.65 00:35, 15 October 2006 (UTC)
- Did you create a system restore point? If so, you can use that. Alternatively, just go into the display properties (right-click on the Desktop and choose "properties") and reset things to the way they were before. Display settings are very simple to change. Or did you have a specific problem that can't be fixed so easily? — QuantumEleven 20:30, 15 October 2006 (UTC)

[edit] Sort or count by word
I have this page that I'd like to sort by color, and also count the number of times a color appears (each color has a 6 digit string, so this is basically a word sort and word count). Can this be done, maybe on notepad or something? Thanks. NoSeptember 14:59, 15 October 2006 (UTC)
- I use EditPad Pro (which you can try for free) as a text editor, it allows you to count the number of occurences of a word (by going on find/replace (Ctrl-F) typing in the search string and pressing count), but there seems no easy way to order the list, is this useful?--Bjwebb (talk) 15:11, 15 October 2006 (UTC)
- I whipped up a quick little program that sorted the list by date. Is this ok? Oskar 18:00, 15 October 2006 (UTC)
- That is very very excellent :). I will link viewers of my list there. Could you run that program once a month (say on the 5th of each month (to allow for my usual month-end updating))? NoSeptember 18:18, 15 October 2006 (UTC)
- Sure, no problem. I should use your page as a source, I'm assuming? Oskar 18:59, 15 October 2006 (UTC)
- Yes. And if you are interested, you could do two versions, one with the semi-active list included, one without. We can dig through the history of your new subpage to find the version we want. And if this ever becomes a bother to you, just post the code on the talk page and we will find someone to do it. As for myself, I am completely non-tech savvy ;). 19:12, 15 October 2006 (UTC)NoSeptember
- Allright, I added sections on semi-active, inactive and former admins. I'm putting a note in my calendar to update it every 5th of the month. If I forget, please remind me ;). The code I used is on the talk page. It's filthy, but it works. Oskar 20:20, 15 October 2006 (UTC)

- That depends entirely on what you want. You can probably get an old PC from someone who is replacing it, or from a company that's getting rid of old material, for very little (under £100). However, it probably won't run modern programs - if that's not a problem for you, then that's your best bet. Check out shops that assemble computers, they can probably point you in the direction of second-hand computer shops. — QuantumEleven 20:28, 15 October 2006 (UTC)

- You might even be able to find a friend or coworker who is tossing out an old computer, and get it for free. The computer I'm typing on was given to me free from my brother's employer, as they were planning on tossing it out anyway. It's old (running Windows 98), but works fine, and I couldn't beat the price. StuRat 22:42, 15 October 2006 (UTC)

[edit] Why one of my speakers will eventually stop working?
It is very common for me to have my stereo+subwoofer or just stereo speakers to become forcefully "mono". Why is that? How can I prevent my new speakers from breaking down? Thanks.
- This might be rather obvious, but just in case, you do realize that when you play mono music on a stereo, it still comes out as mono, right ? StuRat 22:38, 15 October 2006 (UTC)

- Well it still might come out both speakers but it'll still be only one channel of data. --frothT C 20:03, 16 October 2006 (UTC)
[edit] Shell32.dll cannot be replaced because it appears to be in use.
I need to update my shell32.dll to get a program working, but I cannot replace it because "another process is using it". What now? = Mgm|(talk) 17:16, 15 October 2006 (UTC)
- Additional info: I'm using Windows98, so I'm not expecting support from Microsoft on this one. And I get the error message "HC.exe is gekoppeld aan ontbrekende uitvoer shell32.DLL:SHCreateDirectoryExA" which means so much as "HC.exe is linked to missing output shell32.DLL:SHCreateDirectoryExA". I found something about a fix but that was for a specific other problem with that DLL not mine. - Mgm|(talk) 17:33, 15 October 2006 (UTC)

[edit] Rome:Total War -- Low budget alternative
I've tried Rome:Total War at a friend's place. My computer is very low end (around 700 MHz and very little disc space. Can anyone recommend a war game with a similar gameplay but a little less demanding on my system. I specifically prefer non-turn based games. - Mgm|(talk) 19:49, 15 October 2006 (UTC)
- I don't mind low-tech or 2D setups. I do like historical battles (Roman, Alexander, etc) better than WWII. If you know of a free game, I want to hear about it as long as it is not turn-based. Non-free suggestions are welcome too. - Mgm|(talk) 19:58, 15 October 2006 (UTC)
- Well, there are always the precursor games, Medieval: Total War and Shogun: Total War. Both were outstanding for their time, and if you overlook the somewhat dated graphics both still play exceptionally well (I used to play a huge amount of Medieval before getting Rome, and I can attest that it's excellent). — QuantumEleven 20:26, 15 October 2006 (UTC)
- Will those two really work on a 700 mhz computer with no graphics card? I'd recommend one of the classic 2d-rtses, Red Alert 2, Warcraft II, The Settlers III (fantastic game, but you have to have the patience of a small galaxy), etc. Oskar 21:01, 15 October 2006 (UTC)
- Yeah, check out the requirements on the articles. Medieval: Total War requires at least an 8mb video card, but that's still pretty low, and Mgm didn't specify anything in this regard. As Quantum said, it's a excellent game, and despite the low requirements you can still have some massive battles. It just looks somewhat dated compared to Rome:TW and Medieval 2:TW. -- Consumed Crustacean (talk) 00:01, 16 October 2006 (UTC)
[edit] My suck-ass trojan
I've just downloaded this trojan, ntdll.exe. It's not doing anything though. Occasionally, maybe once per day, I'll get a pop-up that explorer.exe has encountered a problem due to ntdll.exe, but that's about the extent of this trojan. None of my spyware scanners can find it. A search for executables created in the past few weeks comes up empty. What's up with it? Hyenaste (tell) 20:32, 15 October 2006 (UTC)
- Just because you aren't seeing anything happen doesn't mean nothing is. It's probably using your computer as a bot and either DDoSing people or sending spam using it. I'd suggest you download Autoruns and see what is starting when you put on your computer. Look for the exe there. Look where it's located, remove it from the list and the drive. This probably won't help you, but do it and report what you get (I'm assuming that you've googled for guides to remove it, yes?) Oskar 20:58, 15 October 2006 (UTC)
-
- Nothing unusual. I wouldn't even think I had one except for that occasional pop-up. Hyenaste (tell) 21:21, 15 October 2006 (UTC)
- Visit symantec.com and get a removal tool. You may not see it, but it may be exploiting a security leak and those can relay all sorts of info from your computer you do not want in wrong hands. - Mgm|(talk) 23:33, 15 October 2006 (UTC)

[edit] Converting Google Video to mpg
Say, I want to convert this google video file I downloaded into an mpeg format. How so? — X [Mac Davis] (SUPERDESK|Help me improve)08:58, 17 October 2006 (UTC)
- That is not possible, A Google Video file is a closed format. But you can download a Google Video file for a Sony PSP or an Ipod, I think you can convert those files to an other format. Tukkaatje 12:44, 17 October 2006 (UTC)

- I don't know if it currently exists, but it should be possible via video capture software. StuRat 13:36, 17 October 2006 (UTC)
- Naevius GVI Converter claims to be able to convert GVI files to the standard AVI format, though I know nothing about it and have never used it, so can't vouch for that. Loganberry (Talk) 14:41, 17 October 2006 (UTC)
- By using regular screenshots, you can capture and re-encode the video. You can then capture the audio as it goes to your sound card. You'll have to get/write the scripts for that yourself though (since Google Video Player is a VLC fork, it should have an option to disable DX overlays).--Frenchman113 on wheels! 22:22, 17 October 2006 (UTC)
[edit] Does Google rank pages by outgoing links?
I thought Google ranks pages by incoming hyperlinks.
Does the number of outgoing links also affect a page ranking?
What effect does this have on Wikipedia?
- As far as I know the basic method involves ranking by incoming links, and it wouldn't make any sense to do it the other way around. I've heard that Wikipedia was granted an especially high rating by Google employees (and I assume many trusted websites are given similar treatment) which may boost articles to the top of the search even when there are few incoming links. I can't say I'm familiar with the methods that page ranking services like Alexa operate on. freshofftheufoΓΛĿЌ 09:17, 17 October 2006 (UTC)
-
- Yes, I'd say only incoming links (weighted with the credibility of the linking page) have any effect. —Bromskloss 11:56, 17 October 2006 (UTC)
- It is my opinion that the age of a website is also used by Google. I've had the same domain name, with an active web page, for many years - long before Google or Lycos or Alta Vista or Yahoo... There are very few sites on the web that link to my website. So, it shouldn't be considered much of anything. But, my site is spidered by Google (and Yahoo and MSN and Ask...) daily. Without the incoming (or outgoing) links to use as a basis for why Google considers my page worth spidering, I'd have to say it is the age of the site. --Kainaw (talk) 17:22, 17 October 2006 (UTC)
- (As directed at the top of this page, please sign your posts using four tildes ("~~~~").
- Automatic page ranking done well is what boosted Google to the top of Internet search engines. The original theory was published, so is no secret. However, any such system can be manipulated, and many folks have a huge financial incentive to do so. Therefore the details of what is done today are constantly changing, and not made public; here's the little Google itself says. Speculation abounds, some better informed than others.
- And did it not occur to you to seek an answer to this question by searching the web? --KSmrqT 04:51, 18 October 2006 (UTC)
[edit] Image comparison script
We get a quite a few questions about identifying sources for pictures, and I swear I've read somewhere (popular science or something like that perhaps?) about programs/a program that index internet images (like google images does) and then compare them using some sort of algorithm to find similarities, and find duplicates.
I've found a couple pages boasting similar abilities, but only for small limited sets of images. Does anyone know of such a program? freshofftheufoΓΛĿЌ 09:12, 17 October 2006 (UTC)
- I've discussed just such a program at the Ref Desk before. It's quite difficult, as it would ideally need to be able to deal with the following:
-
-
-
- Different clipping. For example, a pic should be able to be matched with a close-up of one part of the pic, or two pics which have an area of overlap should be matched.
-
- Different color schemes, 32 bit, 24 bit, 16 bit. 8 bit, greyscale, and even black and white.
-
-
- Mirrored or rotated images.
-
- The most difficult problem, likely requiring some form of artificial intelligence would be to match pics of the same object from different angles.
- You could write a program to do all that, but it would take a long time to compare any two pics. If Google were to try to use it to categorize all their pics, the resources required to get this job done would be extreme. StuRat 13:27, 17 October 2006 (UTC)
-
- If you've ever used a tool which implements the SiFT algorithm, you'd be pretty impressed at how good the feature recognition is. (It deals with stretched, squashed, sheared and rotated images, and image parts.) I wouldn't think it entirely out of the realm of possibility. You'd have to have a human on the end of it, but there are algorithms which can cut down tremendously on the amount of human work. grendel|khan 16:07, 17 October 2006 (UTC)

[edit] Best programming tool for beginner
Whats the best free programming environment for a beginner with no programming experience? It should due GUI stuff and create stand alone executables. Cross platform prefered.
- What about Lazarus, which is based on the open-source Free Pascal and runs on Win32, Linux, MacOS, FreeBSD...? Lazarus is a clone of Delphi, which is itself based on Pascal. It's still a work-in-progress so may not be stable or complete enough for large projects, but on the basis of a few minutes' playing around with it I think it's quite good enough for learning on - and you also have the advantage that much of the huge volume of Delphi documentation will be applicable to Lazarus too. Loganberry (Talk) 14:38, 17 October 2006 (UTC)
- If by environment you mean something broader than IDE, I recommend BASIC. Try FreeBASIC or PowerBASIC. --frothT C 17:15, 17 October 2006 (UTC)
- IMHO, a "beginner with no programming experience" should not be worried about GUI "stuff" and cross-platform executables to start with, but with learning programming. It's like asking what's the best driver's education program? It must allow me to drive an F-1 class Ferrari next week. --LarryMac 19:06, 17 October 2006 (UTC)
-
- Yeah, I agree. Although, VB makes it pretty easy to do GUIs, if I remember correctly. Newbie easy. It's a very BAAAAD way to learn though, you should learn the basics first Oskar 23:35, 17 October 2006 (UTC)
-
-
- Oh yes, VB has ruined many an aspiring programmer's career. Learn it much later if you absolutely must, but otherwise stay the heck away --frothT C 02:08, 18 October 2006 (UTC)
- A beginning programmer needs to learn programming, which is an uncommon discipline. See Category:Educational programming languages for a selection of languages intended to help, most of which come with development environments and cross-platform implementations. Notable examples are Logo, Scheme, and ToonTalk, from the MIT tradition, and the Smalltalk family out of Xerox PARC.
- Programming requires structured thought, structured action, and structured data. Daily life is not adequate preparation for these demands; in fact, most people give terrible directions and unsound explanations. A mistake in a single character in a program can cause it to fail — a daunting challenge when confronting a program requiring thousands of lines of code. Thus programming includes not only problem definition, method design, and program implementation, but also structured testing, structured diagnosis, and structured correction. A final essential is documentation, especially important in a large project.
- Do not be embarrassed to begin with a training environment like Alice; the insights and habits gained there will be more important in the long run than wrestling with the obstacles of a “serious” implementation language like C++. And, paradoxically, the total time to mastery of C++ will likely be shortened by including this learning step. --KSmrqT 06:57, 18 October 2006 (UTC)

I think this might be vandalism, but the first line on the entry for "database" reads like a nonsequitur. I don't have a user account and I'm not sure how to fix it, since when I try to "edit" the line doesn't even show on the edit page - only the published page.

[edit] USB Cables
I am interested in controlling electricity in a usb cable. My aim is to send a small but significant voltage to a device the other end.
I understand that there are three main parts to a usb cable, a live wire, a ground wire and two twisted wires for data.
Can the two power wires be controlled from a computer?
I don't really know what to search for, Google has given me a list of USB based products which doesn't help much and any pages which are related tell me information I already know.
Could you suggest some online resources which would make this easier or explain how i would go about doing it.
Thanks very much
PeteL 18:28, 17 October 2006 (UTC)
- I suppose that actual functionality would depend on your USB controller, but the specification doesn't allow for any variation in power. You're better off just using the power lines for power and resisting it depending on what's on the data lines. USB uses differential signaling to reduce interference so you might want to read up on that before trying to design your own controller. Also the data lines are asynchronous so make sure it's not oscillating before addressing it to the resistors (or variable resistor). Or if I'm totally off here and you don't need variable power, just use the power lines and interrupt them when you don't need power (use the data lines to determine this) --frothT C 18:54, 17 October 2006 (UTC)
- Have you looked at our USB article, and more importantly, some of the external links on that page? --LarryMac 18:59, 17 October 2006 (UTC)

i know this is not exactly a computing question but i hope one of you can help me out. i have a Nokia 3155i (Virgin Mobile edition). i know it can play MP3 and AAC because most of the ringtunes it comes with are in those formats.
