Mar 19, 2011I'm looking for the most pure linux terminal distro. I am trying to learn linux and I have Ubunutu 10.10 installed but I feel like it's not as pure as other distros, like Ubuntu 10.10 is different from the average terminal experience.
Maybe I am wrong about this, but certain things like the grub .lst file is now a .cfg file in Ubuntu, is this replicated across all linux, or is this unique to Ubuntu? Little things like this that make it difficult to learn. Are all the distros unique in this way?

Jun 8, 2011How to remove X completely from the system?
As a Security practice I wanted to disable X from loading.
So i modified following line from /etc/inittab.
id:3:initdefault:
I was then able to start my machine in terminal mode(runlevel 3).
I wasn't satisfied at this stage as i was able to get the graphical console by merely typing code...
Now i have made the above line commented and removed execute bit of the file .
System is now behaving as i wish it would.
I have 2 questions here.
1)Is this Method considered to be stardard while removing X in linux distro.
Will it make any difference?
I m not using any application that explicitly use graphical user interface and i can work in runlevel 3.
2)Is any package responsible for loading X .If yes then removing shall remove X from the system,correct me if i m wrong.code...

Oct 28, 2010I'm cross-posting in order to get as a wider audience to get as much feedback as possible. I am currently studying to learn the ) Gidhlig (Scottish Gaelic language and finding studying by rote out of a book a bit 'limiting'. Because of this, I am thinking about creating a software project which could act as an interactive way to helping me learn the language. I've got a few ideas floating in my head but the direction I want to take is that the software is not an alternative but an aid to be used in conjunction with traditional studying materials. I was thinking possibly small interactive games or exercises that both are fun as well as to test and use the parts of language I have learned. There might also be a bit of reporting to show strengths and weaknesses.
Firstly, the technical specifications, that offhand, I can think of that the project will need to meet:
1. Cross-platform (while I would like it to be just Linux, I have to be realistic that people would rather use Windows)
2. The language data is separate from main program so that the software can be used with other languages.
3. Not too complex so that it is quick and easy to program as I will be doing it myself.........
General :: Distro Better For LEARNING Security Skills?
Jun 27, 2010I currently run Ubuntu 10.04 alongside Vista. I have been looking for a few linux projects to help me learn, the two that I have thought of have been:
1. LFS
2. Something security related
As for no.2, I am interested in learning about network security, intrusion detection, system logging, firewall logging etc. And as a project I would like to work on creating a desktop box as secure as possible, then maybe testing my own box on my home network.
1. Is there a good linux distro that is designed for security?I know people often say "the distro doesn't matter, it only matters how you configure it.
2. Does everyone agree with this? As far as security, learning, etc, are all distros created equally?
Programming :: Saving File Data Using Python In An Embedded System In An Safe And Fast Way?
Apr 19, 2011I 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()?

General :: Installing SDK On Embedded Platform?
Jun 7, 2011I'm trying to install a SDK iso image onto an embedded linux platform. I was able to mount the image on the platform without problems. I also created a symbolic link called "bash" in the bin directory and had that point to busybox to satisfy the first line of code in the installer: "#!/bin/bash". However, when I run the installer, I get an error: "installer: applet not found"
I get the same error when I type "bash" on the command line. Is there a way to fix this? Here is the first few lines of code that causes the error:
