How to download video from Adobe Flash Player 10
I've never been able to actually download the video playing in Flash, and it seems to be no different for the current version. I want to download videos from Flickr so that I can convert them to .ogg and upload. Can someone offer some advice for how one might do this? With the addition and expansion of videos on Flickr, there's much potential for expanding Wikimedia's video collection, but copying files to the Commons for video seems impossible relative to the ease of pictures, which can be done in a few seconds on the toolserver.

I can't install my own programs on the computers I'm currently using. I can perhaps get around this by using a friend's, but is there any option for those without the ability to download and install a program to do it? Would it ever be possible to make the process as simple as pictures, perhaps by having an automatic process do the conversion for us when we upload? Richard001 (talk) 00:56, 19 December 2008 (UTC)

There are both programs you can download, and places on the web that will convert these types of files to .avi, .mpg, etc. http://www.savevideodownload.com/ is one of the sites which will convert the flash files (swf) to a more user friendly movie type file. If you are in a situation where you can't 'install' software, your best bet may be to do a Google or Yahoo search for convert flash to movie file and look at some of those sites. Ched Davis (talk) 01:38, 19 December 2008 (UTC)


 * The site you have recommended only seems to be for YouTube. Can anyone provide me with a site that actually works? (I have tried a few). Richard001 (talk) 02:47, 19 December 2008 (UTC)


 * I don't know that wiki editors usually do searches for others, but maybe http://vixy.net/ would help you. Ched Davis (talk) 03:54, 19 December 2008 (UTC)

BIOS
I cannot find the BIOS on this MOBO. Will someone please point it out? Ζρς ι'β' ¡hábleme! 03:29, 19 December 2008 (UTC)


 * Perhaps you are looking for the CMOS (the battery that remembers your BIOS settings). It's the round circle (battery) in the upper right corner.  If it's a jumper (such as what you would use to reset a password), I'm sorry the picture isn't large enough for my old out of focus eyes to detect. Ched Davis (talk) 03:50, 19 December 2008 (UTC)


 * I know where the CMOS is, but I am trying to upgrade the BIOS on one of my old computers, so I need to find out what BIOS chip it has, or where it would be located. Ζρς ι'β' ¡hábleme! 04:00, 19 December 2008 (UTC)

I've flashed a BIOS before to upgrade, but I guess you want to replace the chip eh? ... what's the model number of the mobo? Ched Davis (talk) 04:25, 19 December 2008 (UTC)


 * Well, I am planning to flash it, but I have to know what BIOS I have to flash it correctly, right? The mobo is a CUW-AM rev 1.02. Ζρς ι'β' ¡hábleme! 05:08, 19 December 2008 (UTC)

Perhaps this is what you are looking for: http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=bph07170&product=81921&dlc=en&lang=en

As far as current version of BIOS, I would think by booting (even from floppy or CD) you could keystroke into the BIOS to tell you what the current version is. I am NO mobo expert, but looked around a bit for ya. I guess it is a: Asus CUW-AM/MEW-AM, but get the impression you won't find much at the Asus site. HP used them and called them: CUW-AM (Tortuga). Are you trying to get it to accept more RAM by any chance? Well, sorry I couldn't be more help ... hope what little I looked for has helped at least point you in the right direction. You'll probably have more luck with Google than Wikipedia on this type of issue. Ched Davis (talk) 06:39, 19 December 2008 (UTC)


 * The device in the brown socket is the Firmware Hub, which contains the flash memory where the BIOS resides. Rilak (talk) 09:58, 19 December 2008 (UTC)

Speech recognition software
I need would like to use one of the free speech recognition programs. Unfortunately, I have no experience with speech recognition software. Browsing the articles, I read about engines, language and accoustic models... and don't really have a clue what they're talking about. (Yeah, the articles are not very accessible for people like me.) I'd sooo much appreciate if someone could give me an easy explanation (or link to one) as to how I install and get one (or more) of those programs going. And yes, I'd prefer to try out more than one program (if possible) because the recordings are of rather poor quality, so it might help to find out which program does the best. (And the rest I'll have to do by hand, I know.) Thanks a million for your help!! --Ibn Battuta (talk) 05:00, 19 December 2008 (UTC) PS: In case you wonder--yes, I'm pretty stressed out at the moment, so please excuse that I'm not taking the time to "work through" our articles... 'cause yes, I've seen enough to realize that for me, it'd be a very long way.


 * Wikipedia is not intended as a how-to guide. But if you go to the websites of the speech recognition software products in question, you'll find documents on what they do and how to use them.  However, none of these speach-to-text enginees seems to be aimed at the end consumer, and not to beginners. (For example, the Sphinx Tutorial will require some familiarity with Linux.)
 * Speech-To-Text technology is in a suprisingly primitive state, and these open source projects seem to be more research than anything else, so the documentation about them is aimed at researchers, not the layman.
 * In any case, I don't think you'll find any package, free or otherwise, that can effectively decode some pre-existing, poor quality, samples of natural language. Speach-to-text programs typically require a "training" period where the voice they will be working with reads a bunch of known text. (They usually force you to read a page from an old novel or something.) Even after the software has been trained to work with a particular voice, using speech-to-text software takes practice. They require you to speak in a very clear fashion with unnatural spaces between the words.


 * I'm sorry, but I don't think you'll find software that will do what you seem to want to do, even if you're willing to pay for it. You're going to have to transcribe your tapes the old fashioned way. APL (talk) 06:01, 19 December 2008 (UTC)


 * I have to agree with the previous poster, as I have in the past wrestled with various commercial and non-commercial speech recognition applications. Speech recognition is an incredibly complex field, and while companies have struggled to package easy-to-use commercial solutions, the free versions available are much more primitive.  If you really can't afford commercial software, then either HTK or Sphinx is probably your best bet (HTK is free for private use I believe, and will work in Windows or unix, but despite numerous tutorials and advice online it is complex to set up), but don't have unrealistic expectations.  If you get it to work at all, you will have to do a lot of checking, correction, and editing on even the best recogniser output.  If you buy something like Nuance's Dragon NaturallySpeaking Professional edition, it will be able to do transcriptions from file - how well it works will depend on many factors, and the output is likely to require substantial checking/correction even on noise-free speech.  It may be cheaper to pay a professional typist, depending on the quantity of speech, and it will certainly be far quicker and more accurate; there is no simple, cash-free, and effort-free solution to your problem. --Maltelauridsbrigge (talk) 13:44, 19 December 2008 (UTC)


 * I agree with the above posters and would also add that speech recognition only works well when you have a severely restricted vocabulary. For example, if it only tries to recognize the words "one" through "ten". StuRat (talk) 15:46, 19 December 2008 (UTC)


 * Just a big thanks!!! to all of you! That helped enormously! Yes, I had expected to have to do a lot of re-checking, but still save some time... but if I won't, I'm really grateful to know this before investing time to understand the software. BTW, I guess the information you provided would also be helpful in the articles... though the problem on Wikipedia is that someone would probably claim that's "NPOV"... Anyways, thanks so much, Ibn Battuta (talk) 22:24, 19 December 2008 (UTC)


 * The usual problem is that technical articles are written by people with a PhD in that field, and, as a result, are utterly incomprehensible to anyone who lacks a PhD in that field. Anyone attempting to add any content for a general audience will then be immediately reverted by the PhDs. StuRat (talk) 01:32, 20 December 2008 (UTC)


 * Yes... though computer geeks seem to be rather good at being incomprehensible as well! :o) Anyways, yes, I see it as one of Wikipedia's biggest problems, especially in the sciences. ... --Ibn Battuta (talk) 17:57, 20 December 2008 (UTC)


 * One approach I've used successfully, after doing battle with the PhDs, is to create a separate "introduction level" article. A few of them won't even stand for that, but the majority of PhDs are satisfied with one article per topic which they can keep utterly incomprehensible to everyone but themselves.

Question about XP popularity
If Windows XP is one of the more disliked versions of Windows, why is it the most used one anyway? 124.180.116.201 (talk) 07:03, 19 December 2008 (UTC)
 * It isn't one of the more disliked versions. Just that simple. Magog the Ogre (talk) 08:49, 19 December 2008 (UTC)

And liked-ness isn't a major factor in things like this. It is a sales decision. Once the new operating system comes out then the shops (and business to business sales) all start pushing the new-version, they slowly stop selling configurations with the old version (by and large) and so the consumer isn't really offered the choice in the big-stores - they buy their DELL with the newest operating system and that's that. The vast majority of consumers won't have any opinion on better/worse because they aren't that technically interested in the system - so after an initial 'getting used to it' period they'll probably find whichever operating system Microsoft serve up is fine. 194.221.133.226 (talk) 11:50, 19 December 2008 (UTC)
 * Googling suggests XP is one of the more popular (not just on sales); in user ratings it is challenged mainly by 2000. --Maltelauridsbrigge (talk) 13:50, 19 December 2008 (UTC)

 * Flash worked for me after I installed flashplugin-nonfree (or something like that). I am not an active user so can't tell if it's buggy, but it only works properly in Firefox (ie not in Opera).

Navigation Columns in Dreamweaver CS3
Hello Wikipedia,

I'm cuurently building a website and I'd like it to have a navigation column on the left hand side, to make it easier to get around. I'm using one of the dreamweaver templates but, when i go to change the background colour for example, it only changes the area outside of where the text is -not WHERE the text is. Is there some way around this? Perhaps there is a better way orf creating what I have in mind..

Thanks,82.22.4.63 (talk) 11:11, 19 December 2008 (UTC)


 * It's been a while since I used Dreamweaver and I didn't use the templates, so take this as probationary advice until someone who actually knows what they're doing comes along. My first thought was that the text area is being kept in a table of some sort. If altering the page properties doesn't work, you may want to try changing the table properties, one of which should be to make the background transparent (or you can just give it the colour you want). Matt Deres (talk) 14:45, 19 December 2008 (UTC)


 * Try using CSS - all of the style-properties (like background colors) of Dreamweaver templates are stored there. Have a brief look at the selectors and you'll understand what you should change. 194.99.216.135 (talk) 12:35, 20 December 2008 (UTC)

How Big is a BIT on a Hard Drive Platter?
Imagine a modern hard drive with a capacity of, say, 1 TB. (SI or binary, doesn't really matter.) The drive has 5 platters of 200 GB each. How much space does a single binary digit take up? 82.2.15.100 (talk) 11:12, 19 December 2008 (UTC)


 * Discrete Track Recording disks have 516 megabits per square millimeter (333 gigabits per square inch). -- Fullstop (talk) 11:18, 19 December 2008 (UTC)


 * That's 1.85x10-9 mm2 or 1.84800 x 10-15 m2 or 1848 square nanometers per bit. If my math is right. --Maltelauridsbrigge (talk) 13:57, 19 December 2008 (UTC)


 * You can figure it out yourself by noting that the typical platter is about 3.5 inches in diameter, with about a 1-inch hole for the axle, and data on both sides, so we get:

diameter_outer = 3.5 radius_outer = 3.5 / 2 area_outer = pi * radius_outer ** 2 diameter_inner = 1 radius_inner = diameter_inner / 2 area_inner = pi * radius_inner ** 2 total_area_per_side = area_outer - area_inner sides_per_platter = 2 total_area_per_platter = total_area_per_side * sides_per_platter bytes_per_platter = 10 ** 12 bits_per_byte = 8 bits_per_platter = bytes_per_platter * bits_per_byte area_per_bit = total_area_per_platter / bits_per_platter

print area_per_bit ~0.00000000000220893233


 * which is about 1425 square nanometers, which is quite close to Maltelauridsbrigge's numbers. At that rate, you could fit the following data on the dust mote pictured at right:

 * One can't use an algorithm like that to determine 'bit' size. First, platters include a quite a bit more than just storage area. Secondly, the algo above assumes a constant 1,000,000,000,000, i.e. 1 TB per platter, which is of course not the case. Third, the algo above assumes that -- as tracks grew longer -- there would also be proportionally more sectors per track (i.e. the outermost track would have about 3 times as many sectors as the innermost track). The number does increase but not proportionally, because otherwise seek times would be proportionally greater too. -- Fullstop (talk) 21:40, 19 December 2008 (UTC)
 * Well, you're right that I put in 1000 GB instead of 200 GB per platter, but after correcting for that I still get within an order of magnitude of M's number above, which is good enough for a Fermi calculation like this (I mean, I eyeballed the 1" hole in the platter, so let's not split bits here). Also, I don't see how tracks and sectors have anything to do with it when we've already arrived at 200 GB per platter, no matter what the layout.  I stand by my envelope! --Sean 23:46, 19 December 2008 (UTC)

Firefox broken downloads notify??
Hi. Is there any way to make Firefox notice a broken/incomplete download and notify it as such, instead of notifying a broken download as "complete"? Thanks in advance, Kreachure (talk) 20:45, 19 December 2008 (UTC)


 * What do you mean "broken?" If you mean a link to something that's not there - Firefox 3 recognizes this and gives a notice. flaminglawyerc 21:52, 19 December 2008 (UTC)


 * No it doesn't, especially from sites like rapidshare it often reports the download complete even though it has only downloaded some of the file. Use an external download manager like Free Download Manager for troublesome links. And also compare the size of the downloaded file to what it really should be, especially for RARs as it will fuck you up to download 90 or so RARs only to find one of the damn files is broken and you don't know which one.


 * I can't figure why it should be hard to figure out which one is broken, if you read your operation log for the unrar/unzip program. (WinRAR it great for this, since it pops up for you with the specific problems, particularly if a certain file is broken.) As for the OP, the only thing you can do, within Firefox, is to check your download sizes. You *might* find an addon/plugin that will handle them differently, but I have doubts, since the one I use (Download StatusBar) can't tell a broken d/l anymore than FF can. --EvilEdDead (talk) 16:02, 21 December 2008 (UTC)

nameservers
I already looked at the article nameserver. I signed up for a site at Godaddy, but want to host my files elsewhere. It tells me to enter 2 nameservers. I signed up for "free" hosting at a free hosting site, (example).com (please, no comments on that). They gave me 2 nameservers - ns1.(example).com and ns2.(example).com. What do I do now? And in case this plan fails miserably - how would I get the domain to point to my IP address? flaminglawyerc 21:49, 19 December 2008 (UTC)
 * Getting a domain name to point at your ip address will require you to 'buy' a domain and set it at to your ip. When you signed up for a free site they generally don't give you access to the rights that will enable you to point that domain to your ip address. But, you can upload a HTM file with a redirect code in it to send anyone trying to look at it to your ip address, but you will need to have a HTTP (and/or a ftp) server running under your ip address. here is a redirect code: 
 * The above information is not correct. If the free hosting site has supplied you with nameservers, you just have to go set those up with the domain registrar. It's pretty easy, as these things go. Even if you didn't have the nameservers it is easy enough to have a GoDaddy domain name point wherever you want as a simple redirect (like (example).com/~yoursite/). --98.217.8.46 (talk) 22:55, 19 December 2008 (UTC)

I have an Acer Aspire 6530G laptop, and I'm trying to create a keyboard driver for it using keyTouch, but I can't identify some of the key symbols, so I was wondering if someone recognised those symbols or could give me some ideas as to what keycode to assign to them. The keys:
 * stylised lowercase e at the top right that looks like the "e" in the Acer logo - triangular button
 * something that could either be a satellite dish or a thumbtack - in the multimedia row, to the right of the "next song" button
 * one that looks like a planet with rings (keytouch-editor recognised it as WWW-Home) - immediately to the right of the above
 * a small humanoid with his arms raised, seemingly constructed out of the pound-symbol (#) or an H with 2 horizontal bars, and a small curl for a head - directly below the e-logo-button, at the far right of the multimedia button row, diagonally above the KP-minus key
 * a sort of sector diagram - a circle with the top part lifted out (Fn-F2)
 * a tapered line forming the outline of an almost-complete circle, with a small bar perpendicular to the broad top end, and a check mark in the centre of the circle (Fn-F3)
 * the outline of a rectangle, a vertical separation bar, and then a rectangle outline with a pincushioned fill (Fn-F5)

Apart from the planetoid button which was identified by keytouch-editor and the Fn-F5 key, which I'm pretty sure has something to do with the screen, I have no idea what any of these symbols are.

Thanks in advance. -- Link (t&bull;c&bull;m) 23:12, 19 December 2008 (UTC)
 * These keys and their functions are defined in the user guide or manual that came with the notebook. If you don't have the paper copy, Acer probably has one available online. I couldn't find the 6530G user guide, but here's an Acer manual for the 6920 series describing what seem to be the same keys. Look under "Easy-launch buttons" and "Hotkeys". --Martinship (talk) 06:51, 20 December 2008 (UTC)
 * Thanks. I hadn't been able to find a suitable manual, but this one clarified a lot. The only symbol I still haven't identified is the human-like figure I mentioned. Your link definitely helped a lot, though! -- Link (t&bull;c&bull;m) 11:07, 20 December 2008 (UTC)


 * If your Acer is like mine (they seem to be pretty consistent) then the little satellite-dish thing is a sliding toggle that turns on and off the 802.11 wireless function. This appears not be function like a key, but to be directly wired to the wireless lan chip. On my Ubuntu linux setup on a recent Acer laptop, toggling this off makes nm-applet notice that the wireless has been disconnected (in much the way it notices when the wired ethernet cable is pulled).   The only deficiency I see is that when one toggles it back on nm-applet doesn't see the physical interface come up and restore the network connection on it - you have to tell nm-applet to disable networking and then reenable - this is unlike its counterpart on Windows, which does restore the network connection.  87.114.130.249 (talk) 14:18, 20 December 2008 (UTC)
