I have a log file and there are many different types of exception in this file. These could be looked as follow:
Code:
One can see there two types of exceptions: ORGNoCompetenceException and SocketException.
I will filter out the name/type of exception and the number of each type of exception. At last, this statistic data will write to file and create a Excel table.
I've the following input file (sorted.txt)

GNU Emacs 23.1.1 I've noticed that if I run Emacs and M-x server-start, I can use the emacsclient program as usual, but if if I start Emacs using emacs --daemon and then try to use emacsclient the new frame locks up and the shell outputs *ERROR*: Arithmetic error. This issue doesn't happen if I use the -t flag to force terminal mode when running emacsclient.

View 8 Replies View RelatedI have problem in installing Fedora10 on to a UsbHarddisk(transend 250GB).
After installation of some packages it is saying that "An exception has occured .It is possibly a bug.file a report to bugzilla.redhat.com".
The problem is that,ihave previously seen this kind of message a month ago.And when i tried to install the second time it is installed.
Can i debug it?

I know a program running in the background can be brought to the foreground by typing 'fg'. So, if
command_line &
really runs the program in the background, my question has just been answered. But then all reduces to this question (yeah, I know; but I'm asking in earnest): does the ampersand sign make the program run in the background?

I installed slackware 12.1 from files i downloaded and converted to cd (images). There are six "disks" i downloaded from the slackware site and converted to images via a homemade .cmd in windows xp and then burned using imgburn.
I partitioned my hd (canibalized from an acquaintance's emachine and connected it to my desktop (1G ram, 2Ghz processor). Booted from disk 1 and fomatted the 80G HD for 2 partitions of linuxswapable at 2G apeice and 2 partitions of bootable linux. (Because i want to try another distro later). I ran the setup installing most everything and all seemed to go well. After i exited setup and restarted, it identifed the cd/hd as normal and then went into some sort of recovery mode with the emachine logo call pcangel, after which it tells me.
STOP: c0000021a (fatal system error) The session manager initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000 0x00000000). the system has been shut down. So, is this indeed an xp error message, and if so, why am i getting it after formatting everything?
I'm trying to make a bash script that takes away two decimal numbers. This is to work out partitioning information.
Code:
hddsize=`sudo parted -s /dev/sda unit GB print | grep "Disk" | tr -d [A-Z][a-z] | tr -d '/: '`
trimsize="1.5"
partitionendsize=$(($hddsize - $trimsize))
I get an invalid arithmetic operator. Not sure how to minus these two numbers. Is it a floating point issue?
I do not understand bash' syntax regarding the use of ((<arithmetic expression>)). $((<arithmetic expression>)) is tokenised to a single word. OK.
Code:

It may not be used where a word is expected. This generates a syntax error. Why?

I have been using GPRS on a Nokia 6230 on PCL 2009 for months, no problems. Got the C5212 2 days back. First, it would not connect using the old wvdial.conf file (the modem was detected on the same ttyacm1 port), throwing up an error I don't recall now. Then I did a wvdialconf, and edited the resulting file, and this time I got an error "Voice line detected".
The phone came with the windows software, so tried getting online on a Win install. The phone connected, but the procedure involved disconnecting the phone (as described by the software itself). Assuming this "disconnection" could be a reason for wvdial to fail, I tried again on Linux. This time I could get online, without a hitch.
Yesterday, I abruptly started facing a new problem "LCD Terminated by Peer". I had used the phone error free for more than 2 hours. Then I disconnected and plugged it again, and voila the error! I have looked at many sites and their solutions. None of them seem to change this situation. The most popular tip is to comment out all lcp related lines in the /ppp/options file. I am using wvdial and kpp, and my options file did not have those lines in the first place.
I am using a Hauppauge HVR-950Q and have the device installed and setup in Linux. I cannot however watch over-the-air broadcasts. If I reboot to Windows, I can watch tv (about 15 - 20 stations).I am using tvtime and get 'No Signal'.The device node /dev/video0 is created, what else am I missing?
View 1 Replies View RelatedI use my old computer as an NAS, so I remove the monitor after I installed linux on it (disconnect vga cable). I use ssh to control the machine and it works fine. Until some day, after kernel/softare upgrade or messing up some configs, I cannot connect to it through ssh, then I have to plug the monitor back, but the monitor says "No input signal". So I have to restart the computer WITH the monitor connected, and the monitor's back!
I think the computer/linux kernel doesn't detect the monitor plug-in event. So how can I start my linux box without a monitor, but when it goes wrong I can still plug my monitor (vga) back and use the console.
Edit: just one pci-e video card, has dvi, vga, tv/out (s-video)
Edit2: Xorg is not running. I just need the console (CTRL+ALT+F1). The problem is, if the machine booted without a monitor connected, it won't give me a pseudo terminal after I attach the vga cable while it's running. Clearly the monitor is not auto detected as usb device. I'm wondering how to let the monitor auto detected.
I am writing a code which communicates between 2 processes created by fork() statement. Parent reads a file and write the data into a shared memory and sends a signal to the child. The child then receives a signal from the parent to start reading. After finishing the read operation the child sends a signal to the parent asking it to resume its action. Some things are going wrong in my code.
1. segmentation error in memcpy() statement.
2. terminal hangs after running the code.
3. Synchronization problem between processes..

I just installed Ubuntu using Wubi and I am having problems with it. I am running an x58 Rampage II Gene with a radeon hd4850. I'm using a polaroid tlx-04240b hdtv for my monitor. After installing via wubi when I select ubuntu from grub I just get a blue screen that says no signal. I had the same problems before when I tried installing ubuntu and I finally gave up after messing with it for a while. Anyhow I finally started trying to figure it out again and I am brand new to linux so i really dont have a clue what to do here. I'm about 70% sure the problem is just the resolution being to high or the proper driver not installed but as i said I've never successfully used linux so i just dont know how to fix it.

My box: Dell Inspiron 1545. lspci results below. I have enabled the Broadcom STA restricted driver.Problems:1. I am noticing in Ubuntu (using Network Manager and Wicd) that I am unable to connect to wireless signals tha are very weak. In my other OS (dual boot), I am able to connect to these weak signals.2. And the speed of these networks is much slower, and the disconnect rate is much higher than in my other OSI am THRILLED with Ubuntu otherwise, just looking to fix this issue so I can use Ubuntu as my primary OS.Could this be an Broadcom STA issue, or Software config issue? etc? Obviously not hardware cause hardware is same on other OS.

View 2 Replies View RelatedI'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?
