GDM PostLogin equivalent for KDM?
by Koustubha Kale 26 Sep '07

26 Sep '07

Hi, I need to run some stuff as root after users log in to the server. Need access to $REMOTE_HOST & $USER etc. This server has KDE & users don't want GNOME. Is there an equivalent to GDM PostLogin/Default for KDE? Or is there any other way to achieve same results like by inserting my code lines in some script Or by putting in a script somewhere? Regards Koustubha Kale

Problem with broken package, Ubuntu 6.06
by Kamaleshwar Morjal [कम लेश्व र मो रजाल] 26 Sep '07

26 Sep '07

Hello, I am a new to the world of Linux. I have Ubuntu 6.06 LTS installed on my machine. And I have a problem with it, I apologise for such a long mail but to be on the safe side, I thought it would be better to describe the problem as elaborately as possible as I am unaware of the functioning of this system. Since this version of Ubuntu did not come with gcc i tried getting and installing it from the internet. But while doing so (I admit I was totally unaware what I was doing..) I somehow messed up with installed packages on the system. The installation of a package called libc6 did not complete successfully and I got some error saying all dependencies could not be satisfied. It also said (although I don't precisely remember the exact message..) that a service called "gdm" is running that interfered with the installation. [Till then I was unaware of the [package managers available on board; my fault! Didn't read the manual!] Then, when i tried using the package manager [The "Add/Remove" utility & Synaptic] the software refused go any further saying there is a broken package on the machine that needs to be removed first. It instructed me to run the command "apt-get -install -f" at the terminal. I did. The message I got there was that two more packages (ubuntu-base & ubuntu-minimal) will have to be removed from the system along with the broken package "libc6". I cancelled the process right there.. Because the warning said it would free up more than 2GB space on the disk on removing the ubuntu-minimal package. I suspect this must include quite essential parts of the system and therefore chose not to remove it then before getting more information about it. But I am not able to install any more packages unless I remove these three packages from the system. Meanwhile I also requested the latest version, 7.04 (Fiesty Fawn) of Ubuntu from the Ubuntu website and have received the disk today. I have seen that it includes updated versions of some of the packages, has gcc preinstalled, and I suppose, is definitely an improvement over Dapper Drake. Now my doubt is: 1. How can I resolve the error on my installed system, 6.06 LTS (the problem described above)? 2. Is removing the package "ubuntu-minimal" from the system safe? Can it be restored to previous state? (I'm on dial-up, downloading 2GB of data is an impossibility!) 3.* Is there another way? can i install the latest software i received today (Ubuntu 7.04) overwriting the previous one, but preserving the user accounts, settings, software and data that i've already stored there? For instance, I've installed Mozilla 2.0.0.6, while v 7.04 comes with Mozilla 2.0.0.3! Can i keep the newer version there without messing up anything? (I also have plug-ins like Flash Player for Mozilla installed..) 4. If not 3, can I at least keep the data on the disk unharmed while installing the new (Ubuntu 7.04 over Ubuntu 6.06 LTS) OS. Asked 1 and 2 just for gaining knowledge about what can be done in such a situation, however I want to install the newer version nevertheless, so please at least show me a way to do at least one of 3 or 4 if possible! I really appreciate your cooperation and concern. { * Here I try to describe the currently installed system's configuration as much as I can comprehend and remember. 1. one password protected user account. 2. dial up connection set up. (for modem set-up, I used the scanModem script, thanks to http://www.linmodems.org/; it was very useful and easy to work with) I use "wvdial" to connect to the internet. 3. Mozilla 2.0.0.6 installed (removed the default 1.x version that was preinstalled), + Flash Player plug-in + loads of Mozilla extensions. 4. I have a dual boot with M$ (khidkiyan :p), so, all doors and windows mounted (read FAT32 & NTFS drives! =)); actually Ubuntu does that by default; no pain. 5. 405 MB of data on the Linux drive. Can I preserve it while installing V 7.04 over V 6.06 LTS. 6. Currently fsck, while booting, gives me an error saying the boot sector and its backup are different, and provides all the offsets/differences that it encountered. If fsck logs it to a file, i can post it here if i know where it is logged, that might give a better picture. } [[ About my internet connection.. Although i somehow know that my connection uses CHAP authentication, i get the following logs at the terminal every time i use "wvdial".. --> Warning: Could not modify /etc/ppp/pap-secrets: Permission denied --> --> PAP (Password Authentication Protocol) may be flaky. --> Warning: Could not modify /etc/ppp/chap-secrets: Permission denied --> --> CHAP (Challenge Handshake) may be flaky. Any information would be really enlightening there.. ]] Thank you very much and regards. :) -- "LUCK i$ the RE$iDUE of GooD De$iGn" kamaleshwar morjal (कमलेश्वर मोरजाल) http://www.eficacy.com/

Revoking/Objecting to Software Patents in Indian Patent Office
by Saurabh Nanda 25 Sep '07

25 Sep '07

http://spicyipindia.blogspot.com/2007/09/spicyip-tidbits_23.html India, prima facie, does not allow pure software patents or business method patents. But that doesn't stop companies from trying. The Indian Patent Office is already being flooded with the patents described as "A web based system to do XYZ" or "A computer system in conjunction with XY to do Z" With no one opposing them (and not enough noise about this, like in the case of pharma patents), there's a high probability that this would get granted. Does anyone know of a concerted effort to keep this kind of cruft out from our country? Any pointers? Nandz. -- http://nandz.blogspot.com http://foodieforlife.blogspot.com

Text Editors versus IDE - Your opinions
by Roshan 24 Sep '07

24 Sep '07

List, Terms used: IDE: Integrated Development Environment CS: Computer Science IT: Information Technology I was thinking about this for sometime now, and realized, that there wasn't any emphasis on the "tools" being used in courses (graduate, postgraduate) (CS and IT). They may not be of utmost importance, but I'll like to know your opinions and choices. 1. Most of the courses use Windows as their OS and have Notepad as the default text editor used for programming languages such as Java etc. Even for HTML, CSS etc, notepad remains the default text editor. Notepad (default) doesn't have any syntax highlighting or other options. Surprisingly, students are told they learn better, if they are not equipped with these. (Text editor features) I wonder, programmers under *nix, have Konsole ( ;) ) based text editors as well as GUI text editors (Just to differentiate for the sake of it: vim, nano and Kate, Emacs, gEdit) which provide syntax highlighting and a host of other options. Are they at a loss? 2. IDEs are great for development. Because, they hide the actual commands of compiling, interpreting / running the program. (some) They also enable the user with point-click tools and generate code for those tools / components. Surprisingly, the same students are allowed to use the Turbo C++ 3.0 (16-bit compiler) IDE with syntax highlighting for C / C++ programs and are able to write typical C / C++ programs later. The question is, are Text Editors better for students to begin programming or are IDEs better for students? (Irrespective of the language) Text Editors in Windows and GNU/Linux have capabilities that allow the process of compilation, interpretation, execution, identation, adding comments, etc. In some sense, Text Editors nearly is an IDE. -- http://www.gnu.org.in ubunturos @ freenode 5, 50, 500, 5000 - Store N number of mails in your inbox.
