I am developing a JavaScript countdown timer. Can I make the timeout alert pop up even when the user is using another application, such as OpenOffice? In my office, the computers have no Internet access and no access to removable media. — Preceding unsigned comment added by 203.116.187.1 ( talk) 02:26, 25 January 2012 (UTC)
What about for older versions of IE, like IE6? — Preceding unsigned comment added by 203.116.187.1 ( talk) 03:47, 25 January 2012 (UTC)
Or at least make the browser button in the taskbar flash? — Preceding unsigned comment added by 203.116.187.1 ( talk) 03:49, 25 January 2012 (UTC)
Could I do this with OpenOffice.org Basic? — Preceding unsigned comment added by 203.116.187.1 ( talk) 03:49, 25 January 2012 (UTC)
I am a student using Pro 4 when I get to the textbook I do not have a text book. Is Pro 5 or Pro 6 compatabile to use in the place of Pro 4 book? Pro 5, Pro 6 and Course 1-25 the same? My computer 2007. If you need ISBN Number 11142465, 111426465, 0840053320. If there is a different way for a different program including a cd and textbook. Your advie would be appreciated.

Hi. How do I perform a query in SQL which selects all items from table A which do not appear in table B? Thanks. -- 163.202.48.125 ( talk) 10:03, 25 January 2012 (UTC)
SELECT * FROM A WHERE id NOT IN (SELECT id FROM B)
would do it.

(SELECT id FROM B)
)? That way it only gets done once. --

SELECT DISTINCT
to keep it to a reasonable size. If you need to do the query regularly you could put it in a
stored procedure.
AndrewWTaylor (

I am stuck in a problem where I have images of a car at various distances and from these I have to estimate the visibility. My approach was to take the Fourier transforms of all images and then filter out the low frequencies leaving only the high frequencies, which correspond to sudden changes in pixel values. Then I made a scatter plot of the mean values of the amplitudes of the Fourier coefficients against distance of the cars to see the general trend.
However the scatter plot is inconclusive. While the amplitudes do attenuate gradually, there are too many outliers. Does anyone know if there is a better metric than mean which could be used to analyze the trend? Thanks in advance! :-) 141.113.85.93 ( talk) 10:15, 25 January 2012 (UTC)
Hi all, someone told me that some person has managed to score a patent for content downloads on iTunes, meaning those in-app purchases you can make, like pay an extra $1 and remove adds etc. Is this true, because it sounds like something that would have been big news? And what is the correct term for content downloads/ in app purchases? I get meaningless hits on google, so I must have the wrong term. Thanks, IBE ( talk) 10:55, 25 January 2012 (UTC)
Thanks - scary business. I've put it as resolved, but people are free to add more, and I'll be back to check - quite an interesting discovery. IBE ( talk) 14:11, 25 January 2012 (UTC)
As caller ID blocking has no effect on the ANI ( automatic number identification) system toll free number uses, I can't find a way to do it without some calling card or VoiP system that costs something like 20 cents a minute. And the free VoiP stuff that give samples are only 3 minutes which is too short. About 20 years ago I read some text that said there was some way to turn the whole ANI system off for the call but then you'd pay for the long distance call, but that was 20 years ago and I don't remember. Are you ready for IPv6? ( talk) 20:49, 25 January 2012 (UTC)
Hi,
According to [5]: "For reasons too complex to explain here, even some systems, like Gmail’s, that don’t allow intruders to make millions of random guesses at a password can still be vulnerable to brute-force attacks." How does this work?
Thanks. Apokrif ( talk) 21:42, 25 January 2012 (UTC)
