If you have been happily using the two NVIDIA display driver packages with yast2:
If this is you, and you recently upgraded, you may find your nvidia display doesn’t work anymore, and fails every time to load a graphical display, kicking you back into text mode. This is really frustrating, because if you’ve been using yast2 to handle your nvidia display drivers, you know that for a long time you could upgrade the kernel without recompiling your display driver. To any linux user of nvidia products, this is a simply blindingly amazing feat of technology. Let’s just forget for a second that users of other operating systems do this everyday in a completely unremarkable way.
Well, NVIDIA thought, just for kicks, they would rename the yast packages you need to use. For no apparent reason, they are now called
So to get your NVIDIA display back, go into yast, uninstall x11-video-nvidia and nvidia-gfx-kmp-default, and install x11-video-nvidiaG01 and nvidia-gfxG01-kmp-default. Then it will work again. Unless you have one of the legacy cards described in http://www.suse.de/~sndirsch/nvidia-installer-HOWTO.html .
Why did they change the name? Who knows. Why did they make the new default packages the new weird name? Who knows. What does G01 mean? Who knows.
I have a new blog for my personal stuff. It’s called something designed to not be googleable back to my name. At some point a random headhunter mentioned my ancient personal page I created in my junior year of undergrad. This freaked me out a little--that people who are thinking of employing me might actually try and find my weird personal ramblings on the internet.
So if you are one of my friends and know my email address, I’ll happily tell you the address of my new personal blog (which currently contains hardly anything.) I’d just ask you pretty please don’t link to it with any personally-identifying links that might associate it with me in a google search.
And if you are, or are thinking about, employing me: I have no personal life, don’t waste time writing a blog, and exist only to work super hard for you. YOU! You are the most important part of my current or future life. Luv ya.
I decided that in the end, even though I’ve neglected my little blog here for so long, I shouldn’t be ashamed if the first post a put in a while is a technical one. So here goes:
If you want to kill one or many processes that all involve the same command or similar command, you can do it with the handy unix command pkill. It will kill all processes containing the string you give it as an argument. Use the -u option to restrict it to a particular user. For instance:
pkill -u joeuser java
to kill all processes with ‘java’ in their name started by user ‘joeuser’.
Another related handy command is pgrep which only lists the process id’s of matching processes and doesn’t actually kill them.
pgrep -u joeuser java
At work the other day, one of the engineers in lab mentioned that braiding power wires was a good way to keep them all together and have any interference affect them all equally, so that the relative voltages would remain constant. It’s a more complicated version of the twisted pair.
Anyway, I realized I had 4 cables, and I only knew how to braid 3 strands. So of course I spent the next few minutes figuring out how to braid more than 3 strands. It turns out it’s easy. You just take the rightmost strand, and moving to the left, weave it over, then under, then over. Then do this process again with the new rightmost strand. And then the new rightmost strand, etc., etc. You can do the same thing with any number of strands, always start with the right and weave to the left. My finely-crafted Windows Paint picture to the right shows the basic idea.
