Bought computer 11 months ago, immediately there were problems. What would happen is, when I logged in after a long period of shut down, the system would BSOD. Then I would restart and everything would be fine, until the next time I shut down for a long time (8ish hours) and got back on. I sent the laptop in (a couple times) and they eventually replaced the RAM and the BSODs went away. This is all on Windows 7 (well started on Vista, switched to Windows 7).
I recently set up a dual boot with Windows 7 and Ubuntu 10.04. I'm experiencing crashes on Ubuntu (the whole system just freezes, can't operate mouse, keyboard, or anything) and the behavior is similar. When I log on after a long period of shut down, the system will crash, but if I restart (actually I have to wait 10 minutes before I restart, if I restart immediately it will crash again) then it is fine, until the next period of long shutdown.
So I'm thinking it's bad RAM, so I downloaded Memtest and am testing each of my sticks (they are each 2GB) individually in the same connector thing (don't know what it is called, whatever the sticks attach to). The test for the first one passed with flying colors. However, the second one is having problems. On test #2, the memtest repeats itself, continuously looping through 0-32767 errors on the right side.
My laptop is an Asus G50VT
The 2 most interesting lines...
Highest Error Address: 000fffffffc - 4095.9 MB // does this make sense? 4095.9 MB on a 2GB stick?
Test 2: 32767 // the 32767 loops back around to 0 and repeats
I have seen command like $rm aa dd cc bb ee then something like $ >> zz // it removes zz also Where aa dd cc bb ee zz are the files in my directory. Do not know exactly.
I have created mobility of 20 nodes and vbr traffic using following attached script I executed the file as ns234 vbr.tcl I got the vbr.tr and vbr.nam but I was unable to load the graph using matlab <trgraph> I thought problem with is vbr.tcl script.
In a new PC I had constantly BSoD. I tracked it down to bad memory modules and took them back to the shop.Specifically the RAM was Corsair. Anyway they said they will do test on memory to confirm. They did tests and admitted the RAM was faulty and gave me a replacement. At this point: originally I bought 2 kits of 4G RAM. One of the kits turned out bad. They gave me a replacement, it does not seem to be exactly the same, though. In any case, I became causious and as soon as I got them I put them in the PC and run KUbuntu memtest. It started showing thousands of errors! (Again!). I removed the new kit and run the test again. No errors. I swapped the slots I put the memory modules and also no errors. I can not understand now. Is the new RAM kit bad or not? Does the slots I place the kits matter?
I am trying to install mysql 5.1.44..so i downloaded the binary package, i extracted it and then followed the instructions that were in the manual but i keep getting this error when running this command
Installing MySQL system tables... 100315 20:07:27 [Warning] Can't create test file /var/lib/mysql/mosty.lower-test 100315 20:07:27 [Warning] Can't create test file /var/lib/mysql/mosty.lower-test
I am having problems installing linux on an old PC with the hard drive shredded, old CD drive, old 1 GB RAM card. I want to make sure the problem is not that the memory is partially bad.I recall that there should be some way to get the BIOS to test the memory overnight, but couldn't find this mentioned in the books I checked or in my notes. I believe that the motherboard is made by ASUS, if that helps. When I power on and hit the delete key, I do get some BIOS options, but memtest is not mentioned.
Downloaded ok and the terminal did it's unpacking and updating thing, then it said I needed to reboot.So I did, and now I can only boot into memtest.I've had this before and the solution was to hold shift down at boot to force grub to appear, then pick a kernel and set it as default in startupmanager once ubuntu had loaded.
But no dice this time, I've tried holding the shift key down (using USB and ps2 keyboards) but I cant make grub appear - straight to memtest every time.
I did updates that came up automatically, and now when it rebooted, I can't go in to anything except memtest. I held shift to see the menu and it still only showed those. I can't loose my data so reinstalling isn't an option for me. Right now I'm using the CD to boot to this. I can see my data on my HDD and its there, but I don't know what to do in order to make it boot to the OS partition (Just switched from Windows 3 days ago).
Shut down as normal last night, no major changed yet after booting this morning my computer went straight into memtest86+. After finishing, and i rebooted, it did it again. So, i held shift to get into the grub.
I'm running Fedora Core 12 x86_64. I started out using the default bash shell (and customized the .bashrc, etc. as necessary) but had to switch to csh for this one scientific package that requires that shell.
The issue is that my $PATH has unwanted redundancy and I can't figure out how to fix it:
Code:
The csh shell was completely new to me so I'm sure I made a mistake somewhere.
Below are the files that might be relevant for diagnosing this problem. I don't think I touched /etc/csh.login or /etc/csh.cshrc but I might have accidentally done so.
according to this [URL] I issue this command sudo chmod -x 20_memtest86+ when I do that I get this error chmod: cannot access `20_memtest86+': No such file or directory I know it is something simple but, I don't get it.
I am running memtest due to memory issues, I am wondering if their is a log file that can be saved to the hhd with the memtest results, I am running memtest from the grub menu.I am running ubuntu 10.10
I have a machine that was running 10.10 and I updated it to 11.04 and now when I reboot I am taken directly into memtest. Any attempt to hit esc during boot is ignored and no matter what I just go into memtest. Here is /etc/default/grub from my boot drive
Code:
ubuntu@ubuntu:/media/c8e24038-87b7-4a9a-87e0-11de250e3f4b$ cat /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg.

I am booting now from a 10.10 USB stick and I can access my boot drive so if I need to change stuff I can.
I ran grub-customiser to set default kernel, and saw the GFX mode setting, thinking "Hey, my monitor is native at 1440x900! I'll use that!" ...Didn't think about how the GFX card isn't initialized at that point, so my res is limited to 640x480... So the first problem was a system hang at the grub menu, with "Input Not Supported" displayed on the monitor.I changed the GFX mode back, and ran update-grub, and with a grin on my face, I rebooted. The grin went away fast, when I saw that none of the kernels showed in the grub menu, and I have only the two memtest entries. It appears that, while all the files are still intact, grub is not seeing the kernels. I had an idle partition of about 13 GB on hand, so after trying all sorts of things, I did a clean install on the little 13 GB partition. Still no dice, after doing an apt-get purge grub etc etc etc on my main Ubuntu partition, to make sure that the new grub was running. I still have only memtest, even though I can open the /boot directory and see the kernel files. I tried going into the grub command line and starting manually, but tab-complete does not suggest any of the kernel files, and tells me that the files do not exist, if I type in their full names.
Using Ubuntu 10.10 and Win XP - dual drives booted by GNU Grub version 1.98 +20100804-5ubuntu 3 Every now and then, a "Memory Test (memtest 86+)" and a "Memory Test (memtest86+, serial console 115200)" line are added to my Grub startup screen. This causes Grub to start-up a different line than I have set to default. (Ubuntu vs. Windows, etc.)
1. How do I edit the start-up Grub to remove the "memtest" lines?
I want to create some files of a specific size containing a repeating pattern. I did some research and found that I can create a file and fill it with (fairly) random data by using dd like so: dd if=/dev/urandom of=myfile.dat bs=$(( 1024 * 1024 )) count=100 (Creates a 100 MB file.) I found that here: Quickly creating large files.
Rather than fill a file with random data, I'd like to use these patterns: 0xaa, 0x55, 0xff, and 0x00 (one per file). Is there a simple way to accomplish this?
I have a weird font problem that occur from time to time on fedora 12,I suspect gdm-user-switch-applet to be the culprit,but I can't say for sure.notice the weird 'r' letter.
I have a kernel error that repeats itself every few seconds that Ubuntu is up. After a couple of hours my /var/log file is up to 625M. It doesn't seem to hurt anything, but I would like to know what's going on.
Here it is in my kernel log:
Code:
Here is its first appearance in dmseg. It repeats mixed in with other stuff untill the end of the log.
I have an MSI U100 Winbook with Ubuntu Workstation 10.04 LTS newly installed (about 4 days ago).
The update manager displayed about 15 or so updates for my 10.04 installation which I installed. Upon reboot, I can not successfully login to the desktop. It will take my username/password, the screen will go black for a couple of seconds, then the error sound, and back to the login dialogue.
A tail on /var/log/messages displays:
atkbd.c: Unknown key released (translated set 2, code 0xf7 on isa0060/serio0) atkbd.c: Use 'setkeycodes e077 <keycode>; to make it known. composit sync not supported
These messages keep repeating. I am able to login at the console just fine. I have enabled root login but get the same issues logging in as root. I have googled and found several articles and postings involving these messages but they are all in reference to upgrading from 9.x to 10.04. I did not upgrade and did not experience the freezing of applications as noted in those posts.
i could find is crunch2.9 password generator but at the moment it does not suport the function that i am looking for. My aim is to generate : 10-character combinations of the following characters (lowercase) 23456789abcdef with no more then 3 same letters repeates no metter side by side or within one line (sequence) so lets say
abcdef1234 accept fabcde1234 accept ffabcd1234 accept which is probably permutation with repetable string ( where abc is not equeal to cba etc .so ti speak position does metter) fffabc1234 not acceptable -----(3 same characters) ffabcf1234 not acceptable -----( 3 same characters event thought not side by side)
so generally we dont want 3 same characters apper in same line.
I have 13.0 installed, everthing works OKI installed 13.1 on a separate partition, and dualbootWhen I use 13.1, there is a problem with sound.It's like in the old days when yu played an LP with a scratch, the track keeps repeating.When I move the mouse, sound will continue OK for a few seconds, then same problem.There is no difference, if I use KDE, XFCE, or just boot in runlevel 3 and use the command lineOnly thing I can find in the logs:Quote: May 28 06:37:10 cannabis kernel: hda-intel: IRQ timing workaround is activated for card #0.

I just finished an install with 4 OS's. DOS, XP, WIN7, and UBUNTU. They work fine no with problems. However, the menu entry to run memtest does not work, However on my other system it works. The failing system is an i7 and the working one is a Core Duo. Both have a lot of ram. The Ubuntu os was copied with GPARTED. So it is identical.The menu.lst was a copy/paste job and then the HDxx's modified as needed. Please take a look and tell me where I went wrong.menulst.txt

I'm trying to find a script that will return me the largest number of repeating characters. Say, I have the following line in a text file: 12345AAAAA6789AAA
I want it to return 5, because "A" is repeated 5 times in this line (more than 3 at the end).
i have spotted that script (something similar that i am looking for)
[URL]
and i just dont know how to use it.I am not a programmer myself and probably no need for learning that just to create one script! modify "wje_lq" script and run it. thing like : "Just redirect standard output to a file in the normal manner" ? and all this
I.Comment out the first definition of *character-set*, by adding a semicon at the beginning of the line.
II.Uncomment the second definition, which just uses "ABC", by removing the semicolon from the beginning of the line.
III.Comment out the first definition of *word-length*.
IV.Uncomment the second definition, which uses a word length of four.

So, when I program my Java applet I am expected to use an event based model, where I run functions in response to mouse clicks and so forth, and I am supposed to return quickly so that the applet can continue looping. But what if I want certain functions to run by themselves on a regular schedule (like every 200 ms or so) without blocking mouse events, repaints, and so forth?
I looked at the source code of one Java applet I found, and it accomplished this by creating extra threads. I was wondering if creating extra threads was the only way to accomplish that, or if there was some more proper way to do it built into the Applet somehow.
