Programming :: Bash: Convert Decimal To Minutes:seconds?
Jan 13, 2011I have a script in the works that reads an MP3 file and gets the track length. Trouble is, it gives me the total seconds, like this:
Sample Track.mp3 = 225.55 seconds
What I'd like to have is that 225.55 converted into minutes:seconds format (in this case, 3:45). How can I do this?

Mar 29, 2011I've got a program that takes keyboard input with BufferedReader and readline(), but readline() is blocking so I can't increment any sort of counter to quit the application after a period of inactivity, because the program is just waiting for an input from readline(). Do I need to create multiple threads, where one thread counts down an inactivity timer, or is there some method of using non-blocking keyboard inputs?
View 1 Replies View RelatedFedora :: Unable To Get Enough Cycles To Terminate Anything?
Mar 3, 2011I have a machine running Fedora 14 and a bunch of movies stored on it as '.iso' images. It is connected to my home theater. I used to use VLC to play these movies and it worked great for a long time. About 4 months ago, about an hour or hour-and-a-half into a movie, the audio suddenly "disappears" and the machine goes CRAZY with almost 100% of the CPU spent writing to the SWAP. At first I thought the machine was locked, but it isn't; it's so doggone busy writing swap. I am unable to get enough cycles to terminate anything. I found the swap activity through System Monitor - it was ABRUPT. Sound stopped, machine became preoccupied with swap.
I have removed/reinstalled VLC, the machine has undergone a couple kernel updates, and I have removed/reinstalled a number of things associated with audio (CD ripper, mpeg stuff, etc.) yet the problem persists. I don't know what happened or when (update-wise). Any body got any ideas? While a solution would be great, I'd also be happy with a couple decent suggestions on what to look for.

Apr 21, 2010I've somehow got it into my head that it's possible to share CPU cycles, though I've no idea where from.So basically that's what I'm asking - is it actually possible to tell one system to 'donate' it's unused CPU time, cycles, whatever they are, for another's use?

Jul 22, 2010I have a couple of question regarding the screen blanker on Gnome desktop.I used to use a 1024x768 display with previous openSUSE distribution. With 11.3, I discovered the new "auto-configure" X feature. The default screen mode was 1600x1200, but I changed it to 1280x1024.My gfx board is a Matrox G400 DH. Hardware acceleration is disable because of a missing mga_dri.so (fall back to software rendering).I find some screen blanker modules are using almost all the CPU cycles. Animations are very slow, and it can take long before a keyboard hit or mouse movement makes to leave the blanker.
So the questions:- Is there a way to define another (smaller) screen resolution just for the blanker ?- Who should I try to convince to add mga_dri.so back in Mesa again ?- When the monitor go to sleep (DPMS), the blanker still is running, uselessly consuming CPU times. (I can see that because at the first mouse/kbd event, the monitor wake up and shows the blanker running.) Is there a way to configure the blanker to stop running when the monitor is sleeping ?- There are some modules which load images from HD (not the diaporama which load images in ~/images). But the shown image is always the default built-in one. Where is the blanker trying to load images from ?
OpenSUSE Multimedia :: Xorg Eatting Too Many Cpu Cycles?
Nov 20, 2010I am running open suse 11.3 and keep up on maintenance. Ever since upgrading to 11.3 I find that the number of cpu cycles is being eaten for apparently nothing. In looking at the system monitor I frequently find that Xorg is using 24% and frequently more than that. What can be done to reduce the cpu cycles, or fix the problem?

View 2 Replies View RelatedUbuntu :: Login Screen Cycles/loops After Upgrade?
Jan 8, 2011I was running 10.04 until yesterday, when it occured to me that I could upgrade to 10.10. So I went to Software Center, set it to get normal releases and left it to do its job. The upgrade appeared to go without a hitch and I rebooted. The login screen appeared. But just before I could click on my username and enter my password, the screen went blank and a second later the login screen was back. But then just before I could click... Undeterred, after half a minute of frantic clicking I did manage to click on my username and get the password prompt. This time, the login screen didn't go anywhere. Yay. To cut a long story short, this is now my standard logon procedure. However, the plot thickens. I appears that instead of 10.10, I ended up with 11.04, Natty Narwhal, which 'was released in April 2011'. If I download an .iso of Maverick and install it over my current version, will it leave my data unharmed AND reset everything so that it works again?
View 5 Replies View RelatedGeneral :: Htop - Find The PID Thats Causing The High CPU Cycles?
Dec 29, 2010Just trying to figure out some stuff with a broken process. A java app seems to sometime get stuck on a loop or something and i'm trying to find out what's causing it using just the following #sysadmin tools at my disposal.
Things like:- htop - find the PID thats causing the High CPU cycles. I'd then want to use /proc/[PID] or lsof -p [PID] or strace [PID] etc. But the PID doesn't exist in 'ps -ef' output so I think htop must be showing me kernel level thread PIDs?
Not sure about the PID's HTOP is actually giving me? I know that some of them are the real PID's that can be accessed through /proc/[pid] etc but others are not but are i assume child processes or more likely threads as child processes are normally shown in a default ps output anyway.
Is someone able to help distinguish to me about what exactly all these other PID's are that I can't manipulate or find apart from when using HTOP.

OpenSUSE Install :: Suspend To Disk Fails After Working For Several Cycles?
Mar 22, 2010I've been struggling with suspend to disk (hibernate if you prefer) for a while, it works after a fresh boot and for several days' worth of overnight hibernation as I go about my work, but eventually it stops working - it gets to the splash screen but the bar only makes it a little way to the left before stopping, and then after a timeout the system just returns to the "session locked" screen - no real error messages.
I've done my best to try to find out what's causing it to break but I'm really struggling, the suspend process doesn't appear to write anything helpful to the dmesg log or the /var/log/pm-suspend.log - the only thing that I've seen at about the right point in time is cifsd, but I can't be sure that it's a problem with cifs as hibernate continues to work immediately after mounting windows shares with cifs.
