Migrating kde data from kde3 to kde4
I have installed oS v11.2 on a clean HD in a box that also contains another HD which contains v11.1/kde3. I want to copy the data from the old system to the newer one, which is no problem except for the data of the kde apps. If it were not for the great difference between the two kde versions, I would simply carry over the .kde directory, and be assured that I had captured all the data. But the v11.1 system contains both .kde and .kde4 directories, and I am not at all sure of how they interrelate. I would be grateful to anyone for comments, advice, and warnings on migrating kde data from one system to the other. -- Stan Goodman Qiryat Tiv'on Israel ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Re: Migrating kde data from kde3 to kde4
If you are going to use kde 4.4 make sure to copy your resource files for example if you are using kaddressbook backup the file : ** *.kde/share/apps/kabc/std.vcf* After resent upgrade (from 4.3.4 to 4.4.3) there was a bug that did not display the contacts. I would recommend to copy also all related to kmobiletools since in resent version it dosn't exist anymore.

What I have is 4.3.5. Mobile tools are not an issue, as I don't have a mobile phone. What I had intended to do was to copy over the .kde4 directory in toto to the same directory in the new system. The question really is what, if anything, do I need to do with the .kde directory. -- Stan Goodman Qiryat Tiv'on Israel ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
Fwd: gcc-4.5.0 Success Story with Freecell Solver
-- Forwarded Message -- Subject: gcc-4.5.0 Success Story with Freecell Solver Date: Sunday 13 Jun 2010, 17:21:00 From: Shlomi Fish To: Freecell Solving Discussions Executive summary: I have built installed gcc-4.5.0 and after Freecell Solver ran faster, after I compiled it with gcc-4.5.0. I've recently gone over my LWN.net ( http://lwn.net/ ) backlog and saw this feature about gcc-4.5.0: http://lwn.net/Articles/387122/ It mentioned the "Link-Time Optimisation" feature (using the -flto flag) which piqued my interest on how well it will work for Freecell Solver ( http://fc-solve.berlios.de/ ). So I set out to try it out. I downloaded gcc-4.5.0 (which took a while due to the large archive size and problems in finding a fast mirror), unpacked it, and read the INSTALL/ notes. After running the appropriate ./configure call, I typed make and waited. For many hours. But it built up successfully, and I was able to install it. I used the following command, which I've stored in a shell script: [shell] #!/bin/bash ~/Download/unpack/prog/gcc/gcc-4.5.0/configure \ --prefix="$HOME"/apps/prog/gcc-4.5.0 [/shell] After installing gcc, I patched fc-solve's CMakeLists.txt to check for the availability of the -flto flag and also enable it at link-time. This went well, and I benchmarked Freecell Solver after being compiled with it. The end result was that it made the standard Microsoft FreeCell 32,000 boards benchmark take 91.0577080249786 seconds instead of 93.6305630207062 seconds , an improvement of over 2.5 seconds and of roughly 2.75%. (Going down to 351.43 boards per second). So it seems like an impressive gain. That was on my Pentium 4-2.4 GHz stationary machine running Mandriva Linux Cooker. Then I set out to do the same on my newer Core Duo x86-64 laptop also running Mandriva Cooker. I installed gcc this time restricting the --enable-languages to c and c++ so it will take less time. After installing it in a prefix, I realised CMake could not find its -flto flag . As it turns out, it was not enabled because gcc-4.5.0 could not find libelf-devel. Installing it resolved it. The difference there was less dramatic than on my P4 machine - about 0.5 seconds were saved out of about 35 seconds running time. However, in general, I'm happy with the results. Thanks to all the gcc developers for their hard work on making gcc better, including improving the performance of many programs.

Re: Migrating kde data from kde3 to kde4
Stan, for KDE 3 -> 4 I copy over only the individual apps' settings, such as Kmail. Those should be in ~/.kde[4]/share/apps. You can copy over that whole directory, but I prefer doing it app by app. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

I too keep /home on a separate partition, and have thought about keeping
the same /home partition intact across upgrades, but I have never dared to
do so. So my situation is different enough from yours that I still need to
ask the following question more explicitly:
Dotan suggests carrying over only ~/.kde[4]/share/apps/. Since
e.g. kmail is represented in both .kde and .kde4, presumably I should
carry over both appName directories. But apps also have subdirectories
~/.kde[4]/share/config/, so there are altogether four appName
subdirectories needed for each kde app. I'd bother copying at all only
for kmail and kaddressbook, because that is where imprtant data are.
But when v11.2 and kde4 install kmail and kaddressbook, will they actually
make use of these directories that came from kde3?

Good plan. Thanks much.

Each distro get the user name as per the distro name and installed partition, and when I've checked that everything works then I simply move my personal files from one /home/user to another. For instance, my current username is karmic1 because I am using Ubuntu 9.10 in sda1. When I installed Ubuntu 10.04 to sda2 I called the user lucid2. That was a bad distro, so I'm still using the old karmic1 user and booting into Ubuntu 9.10. > Dotan suggests carrying over only ~/.kde[4]/share/apps/.

Problems of a desktop Linux distribution GUI sudo
When using my Ubuntu I used to make the following pattern, whenever an update symbol showed up in the "taskbar" above (in gnome it's the upper panel), I clicked on it, entered my password to sudo up the privileges of the update process, and installed the needed packages to the machine. Then I thought, wait a mintue, this is happening all too often! The only security signature I trust here is the shape of the symbol on the taskbar! A malicious program can immitate the update GUI, and lure me to leverage its permissions very easily. It can't be that bad, I thought, I can probably only sudo a known program. Alas, in the latest version of Ubuntu the sudoers file says %admin ALL=(ALL) ALL and the default user is indeed in the admin group. Is that really a problem (I'm probably not the only one who noticed it)? Is it like that in other distributions? In Windows when you're asked to leverage a permission of a program, it shows you the digital signature of the executable asking for privileges (or at least that's how it looks like in the dialog), which is not a very good solution IMHO, but it's at least better than nothing. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

And that's exactly the reason I don't want to change the distribution's workflow. This is not a problem for me, I guess that I can figure out which application is requesting the permission by a quick terminal session, but if I expect to use Ubuntu in home desktop of a non-power user, and if (hopefully) someday linux will gain nontrivial market share, that would be a problem. > > >> In Windows when you're asked to leverage a permission of a program, it >> shows you the digital signature of the executable asking for privileges (or >> at least that's how it looks like in the dialog), which is not a very good >> solution IMHO, but it's at least better than nothing. >> > > That started as an add-on to Windows XP, Windows Defender which originally > was Giant Anti-Spyware.
