partial PS use?
by Trevor Cordes 17 Feb '16

17 Feb '16

Is it possible to use a standard AT (old style) computer power supply just for its +5v out? I have a project and I just need 5v with a beefy amount of amps, and I have lots of AT PS's around that would fit the bill, but I'm wondering if running a computer PS just for its 5v line might damage it somehow? There would be no load on the 12v (and other) lines. Anything I should worry about? Thanks!

a tool for building many related SRPMs?
by Grigory Shamov 17 Feb '16

17 Feb '16

Hi All, Do you know if there is there a lightweight, more or less distro-agnostic (to work on CentOS 6 without big modifications to the system) tool to build a bunch of inter-dependent RPMs from source RPMS? Something like AUR on Arch but for RPMs? Thanks! -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

is a font free?
by Trevor Cordes 14 Feb '16

14 Feb '16

Is there a way to tell if a font is free? A designer gave me some fonts that their web page should use (css font-face src) but I have no idea if these files are free or not. One of the fonts is Myriad Pro Regular. From the net I can see it's easy to download, but that doesn't mean anything. Wikipedia says it's included with Adobe stuff, but that doesn't mean it's free. a) Does anyone know if this font is free for anyone to embed in their web site? b) Is there a generic way to tell if a font is free or not? c) Does anyone care? (My use scenario puts it on an important (read: sue-able) enterprise web site, so I may have to care a bit more than Joe Shmoe might.) Thanks!

Replacement for Adobe Flash Player
by Robert Dyck 05 Feb '16

05 Feb '16

What is a good replacement for Adobe Flash? A number of people don't like the additional software that comes with Flash. Or that Flash requires updates so often. Where I volunteer, a number of people apply updates without looking and don't know where they get all the extra crap. I did a Google and found recommendation on Tom's Hardware for DivX, but the one time I tried it wouldn't play web video. Apparently the website must be formatted for DivX web player, it won't play the same streaming video as Adobe Flash Player. What will play web video, won't crash, won't install adware or other crap, and free? Thanks, Rob Dyck

Weird code showing up in bash history
by Kevin McGregor 30 Jan '16

30 Jan '16

Has anyone seen this happen? On several Ubuntu server systems (10.04, 14.04, 15.10), I'll be scrolling through the bash history with the up-arrow, and suddenly there will be a ton a code with the word "tideway" used in it very often. I'll check the dot-bash_history file, and sure enough there are large sections of script/code in there which I obviously did not type. Where did it come from? How do I stop it? Here's a short sample: tw_command() { cpuspeed=`egrep '^(cpu MHz|cpu clock|clock)' /proc/cpuinfo | cut -f2 -d: | sed -e 's/\.[0-9]*//' -e 's/Mhz//i' -e 's/ //g' | head -n 1`; cputype=`egrep '^cpu[^a-z]*:' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "${cputype}" = "" ]; then cputype=`egrep '^model name' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^arch' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^(cpu model|family|vendor_id|machine|Processor)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; logical=`egrep '^[pP]rocessor' /proc/cpuinfo | sort -u | wc -l`; physical=0; cores=0; threads_per_core=0; if [ "`echo $cputype | cut -c-2`" = "PA" ]; then cpufamily=`egrep '^(cpu family)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "`echo $cpufamily | cut -c-7`" = "PA-RISC" ]; then cputype="${cp(tideway_i=__TIDEWAY; echo ${tideway_i}_CMD_START__; tw_command; echo ${tideway_i}_CMD_END__) tw_command() { cpuspeed=`egrep '^(cpu MHz|cpu clock|clock)' /proc/cpuinfo | cut -f2 -d: | sed -e 's/\.[0-9]*//' -e 's/Mhz//i' -e 's/ //g' | head -n 1`; cputype=`egrep '^cpu[^a-z]*:' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "${cputype}" = "" ]; then cputype=`egrep '^model name' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^arch' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; if [ "${cputype}" = "" ]; then cputype=`egrep '^(cpu model|family|vendor_id|machine|Processor)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; fi; logical=`egrep '^[pP]rocessor' /proc/cpuinfo | sort -u | wc -l`; physical=0; cores=0; threads_per_core=0; if [ "`echo $cputype | cut -c-2`" = "PA" ]; then cpufamily=`egrep '^(cpu family)' /proc/cpuinfo | sort -u | cut -f2 -d: | sed -e 's/^ //' | head -n 1`; if [ "`echo $cpufamily | cut -c-7`" = "PA-RISC" ]; then cputype="${cpprintf("hostid: ");

Red Hat on Azure
by John Lange 27 Jan '16

27 Jan '16

I thought some people on this list might be interested. https://azure.microsoft.com/en-us/campaigns/redhat/ In a nutshell, you can buy your Red Hat machines as a VM directly from the Azure market place. The monthly fees include the Red Hat subscription and support as well as the VM to host the server. There are a few flavors available including a "micro" footprint server. SUSE has been available in Azure for quite some time, now Red Hat is officially available. Note that this is really intended for businesses looking for fully supported solutions. It's not really suited to hobbyists looking for inexpensive DIY. Regards, -- John Lange www.johnlange.ca
