How can I calculate minutes to the next 0:00 midnight is, in a shell script ? Example it may be 07:10 or 22:36 now and I want to find out how many minutes to the next 0:00 midnight is ?
View 1 RepliesI'm trying to calculate the minutes difference between two dates using the function mktime() on c++. The dates will be passed to me as struct tm, and I will use this function many many times. The example below shows what I wanna do:
Code:
int main(int argc, char** argv) {
while (1) {
tm date2;
tm date1;
[code]...
I read the mktime() description on c++ reference, searched google... but there is no light
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

Is there a way to disable that option where the focus is always the left panel?There is a Command option (shortcut Ctrl-u) to swap the panels. I prefer MC simply start with the focus on the left panel.

View 9 Replies View RelatedThis problem has been bugging me since KDE4 starting shipping. In konsole, if you use the default black on white profile, and you start Midnight Commander, the color of the MC screen is the default blue color it has always been. However, if you change to the green on black profile, which is the one that I prefer, and you start MC, the blue changes to some unreadable light robin egg blue which is horrid.
I'm making a huge assumption here, but it looks like something is off with the green on black profile in Konsole. Try it yourself and you will see what I mean. This only started with KDE4, but it still persists through every version to current.
I prefer to use the built-in editor that came with mc, which can be accessed with 'mc -e', however, I find when using midnight commander, if I type 'F4', then I'm presented with nano, which isn't what I want.

After upgrading to Lucid, MC looks ugly - like some colors are missed. Its very difficult to work in MC now - directories and files have same color for example. [fantomas@fantomas-laptop]:-boot.png. Also, applying different themes (skins) changes bottom bar (with menu: F1 F2 etc) button colors only, not affecting colors of panels. Install 4.7.3 build of MC from here: [URL]...

I need a console based file manager for 10.4 and my beloved mc is no longer installable.

Quote:
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade: The package 'skype-common' is marked for removal but it is in the removal blacklist.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
This is most likely a transient problem, please try again later.
I tried again several times in different days and it is the same. I have 10.4 recently updated from my original installation of 9.10. I think it was not a pre-release, I did it automatically from the website and it took a long time. As far as I know, all I have installed is official, except perhaps Skype itself. There seems to be something connected with Skype. But I have exactly the same Skype I had with 9.10, where I updated every few days with no trouble. It is something peculiar in 10.4

View 2 Replies View RelatedI 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.
