The problem is that after updating (by running the command eix-remote update). I still don't get the results expected when doing a search, eg: # eix -l games-engines/spring No matches found. whereas it should list that there is a match in the sabayon (layman) overlay (though not installed) like: spring-88.0 ~amd64 ~x86 because, at least, the above is what I get by using the http://gpo.zugaina.org/ search at http://gpo.zugaina.org/games-engines/spring So, I guess, I must be missing something in my eix configuration, don't I? Besides, under /etc I only have /etc/eixrc/00-eixrc which is the default (all lines in it are comments).

Use this option if you want to see what eix-remote produced. You can make this option the default by setting REMOTE_DEFAULT=1. So in /etc/eixrc/00-eixrc I have set KEEP_VIRTUALS=true REMOTE_DEFAULT=1 and now when doing a search I get results from all layman overlays (either installed or not). I am not sure whether the KEEP_VIRTUALS setting is needed though, because the man page is *not* clear to me. Besides, in the bugs section of the man page, it says: The previous default KEEP_VIRTUALS=true used to confuse people. However, with the new default, nobody will find out that this feature exists. :(

What growisofs definitely causes with formatting the media is to make it slow. Growisofs is not a cleanly writen application. It frequently returns slightly modified mode data to the drive that was fetched before from the drive. The way this new data is created is in conflict with the SCSI standard. Some drives still accept the data others do not. In some cases, sending back identical data will even switch the drive into unwanted behavior. A quick statement could be: It was written in C++ but looks like assembly code Note that there was no update since 5 years and several people reported less problems when using cdrecord instead of growisofs.

[gentoo-user] Disable Screen Blanking
Hi, i am trying to disable Screen Blanking but have been unsuccessful so far. I used various methods: * installed gnome-power-manager and disabled screen power saving * setterm -blank 0 * echoing "setterm -blank 0" to the dev/ttyXs * xset s off * Kernel parameter in Grub consoleblank=0 A kernelsetting for this seem to have existed in older kernels, but seems to have vanished in recent ones. All methods have failed. Does anyone know of a way to just keep the screen on? Thanks, Norman

I think how they typically work, on any OS, is they exploit a bug in the browser (or a browser plug-in) to run code on your local machine, and then that code exploits the operating system in order to get root-level privileges. After it has that, the possibilities are endless... There's nothing special about Linux that would make that scenario play out any better than it does on Windows, but in reality the number of exploits found for Windows has been greater, and the number of Linux web browser users is far fewer, so it's pretty rare to see web pages that target Linux exploits (but I do read about them from time to time). I personally use Firefox with RequestPolicy, NoScript and Adblock Plus. That still won't protect me from a bug in Firefox itself. I suppose if I really wanted to be paranoid I would run it in a virtual machine (but, hey, those can be exploited, too). At some point, you have to just go with it and hope for the best. Either that or turn off the computer. :) > How is html5 going to affect this? Better or worse? HTML5 is already here and you're probably already using it. :) The biggest benefit to using "anything but Flash" is the idea that the code is not in Adobe's hands and that the community would identify and fix bugs sooner. But that's not guaranteed to be the case. A web browser is perhaps the most complicated piece of software most of us will ever run on our computers, and there's a lot of room for mistakes to happen in those millions of lines of code. Anything can happen.

That's the normal case, but by no means the only one. If you have sudoers set up to run any command as root without using a password, well then > > How is html5 going to affect this? Better or worse? I think you need to gain a deeper understanding of how computer software works Dale. You are asking black/white questions, and the world just is not like that. It's all grey. These questions do not have simple answers. Windows well-deserved it's bad rep from many years ago - that came not from bad security or loopholes but more from the simple fact that early Windows had no security to speak of. It wasn't poor locks, there just wasn't a lock, not a door ... oh stuff it there wasn't even a wall to put the door in for many years! Things have vastly improved now and Windows in the hands of someone with clue rates about the same as (more-or-less conventional) Linux in the hands of someone with clue. Lastly, gaining root permissions is no longer the holy grail it used to be. Nowadays first prize is ability to send mail through your mail accounts, access your browsing history, and get into your password wallet. All of which by their very nature, MUST be accessible to the user's account. -- Alan McKinnon alan.mckin...@gmail.com

Does it make sense to apply some sort of burn-in-procedure before actually formatting and using the disks? Running badblocks or something?
