Graphics cards - - - too much 'joy'
by o1bigtenor 10 Dec '19

10 Dec '19

Greetings I had a system built in Jan 2012 which included an Asus P9X79 mobo and 3 Geforce 570 video cards where I've been running a variant of Debian, usually testing, ever since. I ran using 2 of those cards utilizing first fully proprietary drivers and then a couple years ago I shifted to the debian version of the same. This last spring 2 of the 3 cards failed and nvidia retired support for the cards in their current drivers so I went to using nouveau for my graphic card driver. I purchased a Radeon RX570 graphics card and a week ago swapped out Nvidia 570 card. I was unable to even get the system to post on first try (I had all 4 monitors plugged into the gpu). Went back to the Nvidia card and the system is working just fine. Tried the Radeon RX570 again this time only plugging in 1 monitor - - - - the gpu light do come on but I can't tell if much further is happening. I called my purchase point and they requested I send it back to them. They are now telling me that the card is working well on their M$ test machine. I'm not sure what to do or what I did wrong in my install attempt. Any ideas? TIA

Cloud Based versus Openness
by Christopher Browne 03 Dec '19

03 Dec '19

"Local-first software: you own your data, in spite of the cloud" Here's an interesting rabbit-hole for those that are interested in data archival. https://blog.acolyer.org/2019/11/20/local-first-software/ It heads out to a flurry of pretty interesting third party links. What immediately gripped me as interesting was a set of Library of Congress recommendations on "archival " data formats: https://www.loc.gov/preservation/resources/rfs/moving.html Their choices are interesting, and not too surprising. -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"

alternatives to gmail working well in Ubintu?
by Karen Lewellen 16 Nov '19

16 Nov '19

Hi folks, I was going to just ask for alternatives to consider, but want to keep the Linux element here as I mainly use a Ubuntu shell. Now that google is making it profoundly difficult reaching basic html in low graphics environments, I may need a new home. I prefer reading on the web for this account, especially as I use it largely for research needing to follow article links and work with file attachments. Any solid ideas? Thanks, Karen

bug in Intel processors (Skylake and later)
by D. Hugh Redelmeier 14 Nov '19

14 Nov '19

Intel has found a bug in these processors. <https://www.phoronix.com/scan.php?page=article&item=intel-jcc-microcode&num…> The bug must be commonly triggered because I've noticed no reports. Their fix is to patch the microcode in such a way as to turn off one of their accelerations for any conditional jump that ends on or crosses a 32 byte boundary. They claim that this microcode patch will slow down programs somewhere in the range 0-4%. Furthermore, Intel has released changes to GAS (GCC's assembler) that try to avoid the slowed down JCC by adding padding to the program. This too will slow down the program, but less. They have not released changes for the LLVM assembler. Nor for other things that generate x86-64 code. I wondered if the program changes would slow down AMD processors. Apparently not: <https://www.phoronix.com/scan.php?page=news_item&px=AMD-With-Intel-JCC-Asse…> It surely will have increased program size.

Hardcore sed foo
by Giles Orr 12 Nov '19

12 Nov '19

I've tinkered with Bash prompts for a lot of years. That's where this problem originates, but it can be considered just as a thought experiment if you prefer. We have the directory we're in, for example: /Users/gorr/.bashprompt/really/deep/directory/structure/even/deeper (I keep my prompts in ~/.bashprompt/ , and a very long directory name is often a cause of breakage, so I keep one around to break them ...) I want to shorten the directory name to just the first letters: export newPWD=$(echo ${PWD} | sed -e "s@${HOME}@~@" -e 's@ $/.$[^/]*@\1@g') echo $newPWD ~/./r/d/d/s/e/d This does '~' replacement for $HOME and then substitutes the first letter of each directory for the full directory name. Here's the question: if the first letter of the directory name is a dot '.', can sed then capture one character more so that the output would become: ~/.b/r/d/d/s/e/d I think this would be pretty easy with Bash and a loop, but that's a lot of processing so I'd rather not go down that road. I suspect sed is capable of this, but I haven't delved deeply enough into the tool to even know where to start. This may in fact be a regex problem more than a sed problem - either way I'm kind of stumped. I'm open to simpler implementations using other (standard system) tools as well. -- Giles https://www.gilesorr.com/ gilesorr(a)gmail.com
