General :: Thunderbird - Incoming Mail Signal Duration ?
Mar 25, 2011I'm trying to set up my Thunderbird 3.1.8 (running on Ubuntu 10.04 LTS) to play a .wav file of my choice when new mail arrives. The file I've chosen is 8,8 KB in size and lasts 3 seconds. I've selected the "Play a sound" + "Use the following sound file" options in my Preferences, but only the first second (if that) of the sound gets played - both when I click the "Play" button in the Preferences menu to test it, as well as when receiving mail. Restarting the program with my new settings doesn't help.
Actual question(s):
- Is there a limit on the size/duration of the sound one can use for such a signal in this program?
- Is there any way to modify this limit?

View 2 Replies View RelatedGeneral :: Looping Through Csv File To Calculate Avg/min/max?
Sep 1, 2010I have a csv file (id, loc, timestamp, impressions) that I need to derive some low-level calculations from. Im ok with basic sort and grep operations, but this one is challenging my feeble scripting skills (normally I�d throw it into a spreadsheet, but in this case Id like to ultimately create a script that I could automate). Ive already used cat/sort to order the csv file first on location and then timestamp so it looks like this:
Abt001, AA, 2009-01-01 10:51:00, 231
Cup002, AA, 2009-01-01 10:54:00, 3
Saf001, AB, 2009-01-01 10:51:00, 25
[code]....
What Id like to do is output to file a record of the total, min, and max number of impressions for each location. , e.g.
AA6504 3231
AB252525
AC37925109
ZZ35512341
how to do this and Im kind of stuck on how to approach it I think the combined steps of looping through the locations along with the min/max/sum calculations are throwing me. Eventually Id also like to do additional calculations like average, ect. but I think I can figure that out on my own if I can just get this part down.

View 3 Replies View RelatedUbuntu Multimedia :: Jack Stops All Audio For The Duration Of Its Run
Mar 9, 2011I have had no problems whatsoever with audio in ubuntu 10.10. Both input and output have worked great, but alas now there's a problem.
I recently installed ardour2 with jack (using apt-get) but for some reason, anytime I start ardour2 (which starts jack implicitly) all audio stops on the whole computer. That is my computer goes silent. As soon as I exit ardour2 audio resumes.
Also, although this will probably resolve itself when I resolve the other problem, when exporting a project to audio file from ardour2 it exports silence for the entire duration, even when ardour2 is exited and audio has resumed.
I'm no linux novice, so I'm not afraid of command line solutions (I prefer them actually) however I know nothing about jack or audio editing in linux whatsoever, so if you could be very specific about jack terminology that would be great.
Security :: Escalated Privileges - Determine/change Duration?

What is the default amount of time which escalated privileges remain in effect on my system?
Is it possible, if so how, to change this amount of time?

Nov 5, 2010I have the following problem;When I concatenate several mp3 files the time duration is falsely detected by Rhythmbox when I open the newly created mp3 file. VLC Player however detects the correct time duration. I tried two ways of mergen the mp3's and both have the same falsely result. - mp3wrap- catI currently fixed it by opening the mp3 in VLC player and converted it again to a mp3 file which resolved the issue at hand. However this is not a solution I would like to have, nor a answer to what is the cause of the problem.So my question is simple -- what is the issue with the mp3 file and why is Rhythmbox indicating a falsely time duration?
View 3 Replies View RelatedUbuntu Networking :: Low Retention Duration For Cached Addresses By DNSMASQ
Nov 12, 2010I am experiencing severe DNS delays today, so I tried to install DNSMASQ by following the instructions given on several pages on the web to make it function as a local DNS cache.
The installation was successful, and after editing the configuration files as instructed, I now have a working DNS cache on my computer.
However, it seems that the addresses are not cached for a long time ; for a given domain, the speedup lasts for a few minutes. If I try to access a previously visited domain once more after several minutes, a new (slow) external lookup is made.
Since websites' IP addresses are not changed every five minutes, would there be a way to tell DNSMASQ to keep the IPs in the cache for a long time (several hours at least) ?
This is very important for me because the DNS lag that I am experiencing makes external lookups last 10 to 20 seconds.
