[gentoo-user] bash script question
I want to use an if/then that tests for the existence of a string in 4 files. Usually I do this by checking the exit code of grep, when i'm checking a single file. However, I cant get the syntax right for multiple checks. To troubleshoot I’ve dropped back to just checking two files, and i’ve tried things like If [ $(grep blah file1.txt) –a $(grep blah file2.txt) ]; then But this matches if grep fails both times as well as when it matches both time. Any ideas?

I think the key argument for a DE is integration - all the k* apps built to use k* libraries and backends, allowing them to share data and resources easily; and all the gnome apps using gnome libraries, etc. The main differences I see between KDE and GNOME (aside from the GTK/Qt differences) are that KDE feels like a much more modular approach (while still allowing integration with backend services), whereas GNOME tends towards a one-piece uniform (sure you can theme it (with an external addon) but it's still gnome-shell) user-friendly (hide the buttons you can break it with) environment; and to be honest I like features of both. I think this is why it comes down to a matter of taste, because in the end it's a question of what you find suits your needs. I like the modularity and, I guess, the traditional feel of KDE; but kdepim loosing a large portion of my work email kind of made me balk at using it for a while, and my requirement for MS Exchange integration (not by choice) meant either a (non-free though nicely functional) plugin for Thunderbird ([0] for those interested) or switching to GNOME/Evolution (which, admittedly, has it's own issues, but hasn't eaten my mail yet).

I have signed up for it, and therefore KDE needs to either: 1. Prompt for a 2-factor code on every login and either use the cached google password or prompt for it as well. 2. Use a google application-specific password. This does not require a 2-factor code and operates fairly simliarly to how things work without 2-factor. I just tried re-connecting KDE with Google. It prompts you to login via a webpage and authorize the application. This login screen does not accept an application-specific password.

There was no particular reason, other than to maintain consistency in

Sometimes, I find double square brackets to be a bit of an eyesore, but
do tend to use them more often than not.
I particularly like double parentheses for checking exit codes assigned

(( $? )) echo something went wrong

Not some kernel module that distributes existing code to different nodes. This kind of clustering also has no benefit for most uses. You really need to design your tasks for these kind of environments. i would love to know the mechanism behind dell's equallogic san as it really is clustered lvm on steroids. GFS / orangefs / ocfs are not the easiest things to setup (ocfs is) and i've not found performance to be so great for writes. I have seen weird issues when using Oracle's filesystems for anything not Oracle. How important is reliability? DRBD is only 2 devices as far as i understand, so not really super scalable i'm still not convinced over the likes of hadoop for storage, maybe i just don't have the scale to get it? I wouldn't use Hadoop for storage of files. It's only useful if you have a lot (and I do mean a LOT) of data where a query only returns a very small amount. Performance of a Hadoop cluster is high because the same query is sent to all nodes at once and the answers get merged into a single answer along the way back to the requestor. I don't see it as a valid system to actually store important data you do not want to risk losing. the thing with clusters is that you want to be able to spin an extra node up and join it to the group and then you increase cpu / storage by n+1 but also you want to be able to spin nodes down dynamically and go down by n-1. i guess this is where hadoop is of benefit because that is not a happy thing for a typical file system. Not necessary. That is only one way to use a cluster. It's also an easy and cheap method of increasing the available processing power. This only works properly if the tasks can be distributed over multiple nodes easily. Having the option to quickly add and remove nodes make it difficult to keep the data consistent. Especially Hadoop prefers the nodes to stay available as there is no single node containing all the data. There is some redundancy, but remove a few nodes and you can easily loose data. network load balancing is super easy, all info required is in each packet -- application load balancing requires more thought. this is where the likes of memcached can help but also why a good design of the cluster is better. localised data and tiered access etc... kind of why i would like to see a pvm kind of solution -- so that a page fault is triggered like swap memory which then fetches the relevant memory from the network: That is going to kill performance... Have a look into NUMA. It's always best to have the data where it is being processed. Either by moving the data to the processing unit, or by using a processing unit local to the data. Moving data is always expensive with regards to performance. This is how Hadoop clusters work, the data is processed on the node actually having the data. The result (which is often less then 1% of the source-data) is then sent over the network to another node, which, at this stage, merges the result and passes it to another node. This then continues until all the results are merged into a single result-set which is then returned to the requesting application. bearing in mind that a computer can typically trigger thousands of page faults a second and that memory access is very very many times faster than gigabit networking! [1] http://www.csm.ornl.gov/pvm/pvm_home.html Looks nice, but is not going to help with performance if the application is not designed for distributed processing. -- Joost

There is a reason why Koffice is an office, while 'gnome office' is a bunch of apps that don't know each other. But back to NIH. KDE developed dcop - and dcop was awesome. You could script your entire KDE desktop with a bunch of simple dcop commands. But that was not good enough for gnome. They, and the freedesktop.org they infested were adamant: there must be a new desktop bus - it would be called dbus and waiting for gnome and the demands of gnome-devs held back KDE development
[gentoo-user] Changing glibc
Hi, I am using a closed source software package on my 64 bit gentoo linux system. The software package is beyond compare by scooter soft. Because of the way this package is built, it needs a specially patched version of glibc. I have patched my existing glibc version (2.18) and have been avoiding updating my glibc since. Now I am wondering whether the latest update of bcompare will work with the latest glibc (2.19). So, if I upgrade to 2.19 and the package doesn't work, how can I go back to the working, patched 2.18? I know that portage issues the most scary warnings when you try to downgrade glibc. So what does the community recommend? -- Timur
Re: [gentoo-user] Changing glibc
One option is to copy the glibc version you want to some other directory and set LD_LIBRARY_PATH before starting the executable. Running ldd on all the executables/shared libraries in question should give you a list of all the shared libraries you might need to copy to a safe place.

You should be able to downgrade glibc, provided that you haven't built and installed any new packages following the transition from glibc-2.18 to glibc-2.19. That said, I would suggest that you back up the root filesystem as a contingency measure. Still, why not test bcompare in a chroot? The latest stage3 tarball probably includes glibc-2.19 by now. --Kerin

Thanks a lot guys for the helpful responses. I will definitely try all of them, just for the learning experience, even if one does take care of the problem. Cheers! -- Timur
