Android data transfer
Will all my game data transfer over to the new phone once I login to my Google account and download the apps or no? C T F 8 3 !  03:35, 4 March 2013 (UTC)


 * Fixed the formatting for you. I see no reason to believe that your game data would transfer automatically. Most mobile applications are not that sophisticated, so I think it would be better if looked into to some backup software for your phone. However, you'' have to run around trying to figure which folders to the save data into. — Melab±1 &#9742; 03:43, 4 March 2013 (UTC)
 * Thanks I always have mobile editing issues. Is all data saved on the SD card or is some on the phone itself?  C T F 8 3 !  03:48, 4 March 2013 (UTC)

How a musical transcriber would work
There is a program that opens an audio file and prints the notes that are playing according to the time the notes are played, I want to know how it would work? How a program that "detects" notes would work such as this one? Or does anyone know a similar program that is open source? PS:Wrong Section? 190.60.93.218 (talk) 14:19, 4 March 2013 (UTC)
 * No, the section is ok. Take a look at Fourier transform, and in particular at Fast Fourier transform. This mathematical algorithm can detect with reasonable accuracy which fundamental notes contribute to the overall sound for any given stretch of time (as long as it's "long enough", i.e. much longer than an individual period of vibration of the lowest tone of interest). --Stephan Schulz (talk) 14:30, 4 March 2013 (UTC)

720p CVT-RB
Unless I am mistaken, the specifications for 720p@60 CEA-861 video are:

59.940 Hz Refresh, 44.955 kHz Vertical, 74.176 MHz Horizontal.

What I cannot find are the specs for 720p@60 CVT-RB (reduced blanking) video. I have searched and searched. Does anyone know where to find those specifications? --Guy Macon (talk) 19:12, 4 March 2013 (UTC)


 * Were one to have access to such a specification, if it even existed, it might be under a license or disclosure agreement. CEA standards are not free in any sense of the word.  Nimur (talk) 19:21, 4 March 2013 (UTC)


 * While CEA-861 is indeed a CEA standard, I was asking about CVT-RB, which is a VESA standard (Coordinated Video Timings, VESA-2003-9).


 * While many VESA standards are freely available, alas VESA-2003-9 is not one of them.


 * That being said, the Refresh, Vertical, and Horizontal frequencies of a particular video mode are covered by fair use. The timings for 1080p standard blanking and 1080p reduced blanking are widely available on any number of websites, as are the timings for 720p standard blanking. It is only 720p reduced blanking that is hard to find. This is probably because with 1080p you need reduced blanking to make it work with a standard DB-15 VGA connector.


 * I suspect that getting those frequencies is just a matter of having good Google-Fu. :) --Guy Macon (talk) 01:46, 5 March 2013 (UTC)


 * BTW, VESA-2003-9 is available on multiple websites, including this one. (despite the "Microsoft Word" in the URL, it is a PDF document). It talks about calculating the timing from a formula, but does not specifically list timings for 720p RT. --Guy Macon (talk) 01:58, 5 March 2013 (UTC)

Keep downloading, but doesn't work
I need to open up a PDF archive but it keeps asking me to download the latest version of the PDF viewer of Adobe. I keep downloading the latest version but it keeps asking me to do the same. What's the problem? Thank you in advance. Have a nice morning from the Federated States of Micronesia. FMicronesian (talk) 22:18, 4 March 2013 (UTC)
 * use another PDF reader. 181.50.189.29 (talk) 23:40, 4 March 2013 (UTC)
 * yeah, adobe is a real PITA with all its updates.. I can recommend foxit reader. Vespine (talk) 03:30, 5 March 2013 (UTC)


 * What keeps asking? ¦ Reisio (talk) 04:26, 5 March 2013 (UTC)


 * It's likely that you don't have admin priviliges, so when the updater tries to run (and overwrite protected files) it fails (and it's too dumb to check to see why and suggest to you what you should do). You should manually download the latest version (from Adobe's website), save the installer file to your computer, and then run-as-administrator on that file. 31.185.196.159 (talk) 14:45, 5 March 2013 (UTC)
