I am writing this because I want to keep all of the things that I have now on my ubuntu 10.
4 computer and do not want to upgrade until I have some way of keeping all of the things that I currently have on it.Sohow so I make this happen? Should I try to load these program settings on a flash drive?
i'm using centos 5 and i want to save my setup when switching the user.when i switched user from user1 to user2 and then i logged in user1 back without shutting down, i couldn't see any working window on user1. But since it's working on the CPU, i guess it's working but i cannot just see the window(such as terminal in my case) i was using. i have been using scientific linux which have "save current setup" when logging out. but centos seems not to have that check box!i want to know whether centos can contain the setup for each user when switching user.
View 5 Replies View RelatedI'm looking at running -current instead of 13.1, and wondering about 'upgrading' to -current, as well as running multi-lib. I found the following procedures from another post of about a year ago, but I'm not sure from what directory to run such a script:
Code:
# Upgrade to Slackware64-current
upgradepkg --install-new slackware64-current/slackware64/*.t?z
# Download compat32 stuff
[code]....
Should the procedures above work for me? and although I know that things may occasionally break here and there (and get fixed too), are there any known issues right now that would break things on my machine?

This would include, any issues with potential data/driver losses as well as recovery procedures that may be used if something would happen to it during the upgrade.

1. I have a template file which will be filled in by a technician, meaning it's filled with comments (#) and variable = value combinations, where the technician needs to fill in the values needed under the section referring to the configuration he's performing. 2. After installing from DVD/ISO, the software RPMs get installed and there is a default configuration file containing variable = value combinations where the values need to be changed to the values indicated in the template file mentioned in 1.
In order to do this I played around (and Googled a lot) with ConfigParser. I can load the template, get whatever value I need, load the configuration file, set the new value to the correct variable and write the file.
I checked that the template and configuration files loaded (open()) contain everything, including comments. However when I write the configuration file all comments get lost.
Here's what I have so far: Class to create a fakesection header since ConfigParser needs sections and the configuration file doesn't have those.
Code:
class FakeSectionHead(object):
def __init__(self, fd):

View 2 Replies View RelatedI have one machine where I have several versions installed on different partitions. The base partition (/dev/hda1) is Slack 12.1. On a spare partition (/dev/hdc4) I had installed Slackware64-current. Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot. I know that with the new kernels the hd* designation has been removed, and have already redone that fstab (accessing it from a different boot) to reflect the sd*.

I've upgraded Slackware-13.1 I had installed to Slackware-Current using a local tree I had download with mirror-slackware-current.sh script, but when I rebooted I could not get the graphics to load.

View 4 Replies View RelatedI am accessing a firewire camera using the libdc1394 library and saving the image as a PPM file, using the code below:
[Code].....
My question is whether the above code is portable. I presume it is, since the result is a binary PPM file which should be capable of being read across multiple computers with different architectures and different operating systems. But at the same time, all that the above code is doing is just saving the binary representation of unsigned chars on the harddrive, and there does not seem to be any reason why the binary representations of the unsigned chars will be identical across multiple computers.
I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

So: bottomline: if I upgrade to the new JRE - use the alternatives configurator to use that in the browser, will the software written in the current JDK (1.6) still work? Or: is Java downward compatible?

I've got some bash scripts that I'm testing which operate on different screen sessions under different usernames. In order to check the status of them, however, I have to attach the screen sessions to my current terminal.
I run into problems, though; I only allow SSH to my machine from one username; the others shouldn't need SSH access. So, I log in as one user, and su into whichever user I need. Without performing a chmod o+rw on the terminal before I su into a different user, screen complains that it can't reattach to my terminal, because the user trying to make it attach doesn't have the permissions to do so.
Seeing as I forget to do this a lot, I wanted to make a script that I'd run on log-in to do this for me. Unfortunately, I don't know if there's a bash variable that refers to the current terminal - I can't always guarantee that I'll be logging in to /dev/pts/0, especially if my internet connection gets cut and I leave a hanging terminal...
Is there a variable for that or a way to refer to it in a script? If not, how do I work around that?
