hello, this is likely not the correct forum to ask the question as to why cvs is not keeping log messages upon commit. can someone point me in the correct direction? thanks, awb reticulate - being or involving evolutionary change dependent on genetic recombination involving diverse interbreeding populations

I installed VLC on my computer (fedora 21) with the purpose to play .VOB files. Actually I can run LVL on the line command, but I am not able to do anything in this way... The help command give me this output : --------- > help +----[ CLI commands ] | add XYZ . . . . . . . . . . . . . . . . . . . . add XYZ to playlist | enqueue XYZ . . . . . . . . . . . . . . . . . queue XYZ to playlist | playlist . . . . . . . . . . . . . show items currently in playlist | search [string] . . search for items in playlist (or reset search) | delete [X] . . . . . . . . . . . . . . . . delete item X in playlist | move [X][Y] . . . . . . . . . . . . move item X in playlist after Y | sort key . . . . . . . . . . . . . . . . . . . . . sort the playlist | sd [sd] . . . . . . . . . . . . . show services discovery or toggle | play . . . . . . . . . . . . . . . . . . . . . . . . . . play stream | stop . . . . . . . . . . . . . . . . . . . . . . . . . . stop stream | next . . . . . . . . . . . . . . . . . . . . . . next playlist item | prev . . . . . . . . . . . . . . . . . . . . previous playlist item | goto, gotoitem . . . . . . . . . . . . . . . . . goto item at index | repeat [on|off] . . . . . . . . . . . . . . toggle playlist repeat | loop [on|off] . . . . . . . . . . . . . . . . toggle playlist loop | random [on|off] . . . . . . . . . . . . . . toggle playlist random | clear . . . . . . . . . . . . . . . . . . . . . clear the playlist | status . . . . . . . . . . . . . . . . . . . current playlist status | title [X] . . . . . . . . . . . . . . set/get title in current item | title_n . . . . . . . . . . . . . . . . next title in current item | title_p . . . . . . . . . . . . . . previous title in current item | chapter [X] . . . . . . . . . . . . set/get chapter in current item | chapter_n . . . . . . . . . . . . . . next chapter in current item | chapter_p . . . . . . . . . . . . previous chapter in current item | | seek X . . . . . . . . . . . seek in seconds, for instance `seek 12' | pause . . . . . . . . . . . . . . . . . . . . . . . . toggle pause | fastforward . . . . . . . . . . . . . . . . . . set to maximum rate | rewind . . . . . . . . . . . . . . . . . . . . . set to minimum rate | faster . . . . . . . . . . . . . . . . . . faster playing of stream | slower . . . . . . . . . . . . . . . . . . slower playing of stream | normal . . . . . . . . . . . . . . . . . . normal playing of stream | rate [playback rate] . . . . . . . . . . set playback rate to value | frame . . . . . . . . . . . . . . . . . . . . . play frame by frame | fullscreen, f, F [on|off] . . . . . . . . . . . . toggle fullscreen | info . . . . . . . . . . . . . information about the current stream | stats . . . . . . . . . . . . . . . . show statistical information | get_time . . . . . . . . . seconds elapsed since stream's beginning | is_playing . . . . . . . . . . . . 1 if a stream plays, 0 otherwise | get_title . . . . . . . . . . . . . the title of the current stream | get_length . . . . . . . . . . . . the length of the current stream | | volume [X] . . . . . . . . . . . . . . . . . . set/get audio volume | volup [X] . . . . . . . . . . . . . . . raise audio volume X steps | voldown [X] . . . . . . . . . . . . . . lower audio volume X steps | achan [X] . . . . . . . . . . . . set/get stereo audio output mode | atrack [X] . . . . . . . . . . . . . . . . . . . set/get audio track | vtrack [X] . . . . . . . . . . . . . . . . . . . set/get video track | vratio [X] . . . . . . . . . . . . . . . set/get video aspect ratio | vcrop, crop [X] . . . . . . . . . . . . . . . . set/get video crop | vzoom, zoom [X] . . . . . . . . . . . . . . . . set/get video zoom | vdeinterlace [X] . . . . . . . . . . . . . set/get video deinterlace | vdeinterlace_mode [X] . . . . . . . set/get video deinterlace mode | snapshot . . . . . . . . . . . . . . . . . . . . take video snapshot | strack [X] . . . . . . . . . . . . . . . . . set/get subtitle track | | vlm . . . . . . . . . . . . . . . . . . . . . . . . . load the VLM | description . . . . . . . . . . . . . . . . . describe this module | help, ?

From another response, what I have actually ended up with is: system("ssh localhost 'find /home/... -maxdepth 1 -type f \$ -name \*.mp3 -o -name \*.m4a -o -name \*.flac \$' ") Thanks!

Thanks for that, detox is nice but if I was going to be thinking about renaming files in this case I would use my own method eg: File: 01 Om Namaha Shivaya.flac detox produces: 01_Om_Namaha_Shivaya.flac but I would do: 01_OmNamahaShivaya.flac > Date: Sat, 20 Feb 2016 20:05:19 -0700 > From: jd1008 <jd1008(a)gmail.com> > > > What I do is: > > find <some dir> -name \*.mp3 -o -name \*.flac -o -name \*.mp4 > > and I get ALL the files with those extensions listed. > > Notice: No quotes!!!

Fedora 23 Gnome Online Accounts Issue
by Shawn Iwinski 22 Feb '16

22 Feb '16

When trying to add a new Google account to my Fedora 23 Gnome Online Accounts, I get error "Unacceptable TLS certificate". Watching "journalctl -f" when trying to add the online account, I see "org.gnome.ControlCenter.SearchProvider[2580]: (WebKitWebProcess:5809): GLib-Net-WARNING **: couldn't load TLS file database: Could not parse PEM certificate: ASN1 parser: Error in DER parsing." Googling for a solution has not turned up anything :( Any suggestions? $ cat /etc/fedora-release Fedora release 23 (Twenty Three) $ uname -a Linux siwinski-fedora-w541 4.3.5-300.fc23.x86_64 #1 SMP Mon Feb 1 03:18:41 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux $ rpm -qa | grep -i cert fedora-cert-0.5.10.5-2.fc23.noarch ca-certificates-2015.2.6-1.0.fc23.noarch $ rpm -qa | grep -i gnome-online gnome-online-accounts-3.18.4-1.fc23.x86_64 gnome-online-miners-3.14.3-3.fc23.x86_64

patch listed as missing
by thibaut noah 22 Feb '16

22 Feb '16

Following my kernel compilation issue i used another method to get the source. I added : # custom patch for acs override support Patch6666: override_for_missing_acs_capabilities.patch in my kernel.spec The patch is in rpmbuild/SOURCES but when i run the build it says the file is missing. Also to noted i wasn't able to apply the patch following documentation simply because it seems the patch application changed entirely ? So either the patch listed is apply automatically with the other in the code or i need to find the proper place to apply it. I posted below the command i use to build following by the error message, second paste is the sources i used. http://fpaste.org/326707/00190714/ http://ur1.ca/ojtmz It seems i'm really close to succeeding in the case the patch is workng, just have to solve this and i should have proper patch kernel

Inconsistencies with tracer
by Patrick O'Callaghan 22 Feb '16

22 Feb '16

After updating with dnf I usually run "sudo tracer" to see what needs to be restarted. I've noticed that the results are often inconsistent, e.g. after a recent update I get: You should restart: * Some applications using: kdeinit4 * These applications manually: abrt-applet chrome dolphin evolution evolution-addressbook-factory evolution-addressbook-factory-subprocess evolution-alarm-notify evolution-calendar-factory evolution-calendar-factory-subprocess evolution-source-registry file.so firefox firewall-applet goa-daemon goa-identity-service gvfs-goa-volume-monitor gvfsd-smb-browse insync kaccess kded5 kdeinit5 kglobalaccel5 kmix konsole krunner kscreen_backend_launcher ksmserver kuiserver5 kwalletd5 mission-control-5 plasmashell polkit-kde-authentication-agent-1 qbittorrent xembedsniproxy yakuake Additionally to those process above, there are: - 6 processes requiring restart of your session (i.e. Logging out & Logging in again) Note that last line. I exited the session and immediately logged into a (non-GUI) console as root, then ran tracer again, getting this: You should restart: * Some applications using: service firewalld restart service gssproxy restart service libvirtd restart service nmbd restart service smb restart service sshd restart service tuned restart * These applications manually: cagibid cupsd fail2ban-server rsyslogd Additionally to those process above, there are: - 1 processes requiring reboot Again. note the last line. So there are two issues here: 1) The first run of tracer didn't spot a bunch of services and other demons that needed to be restarted. 2) It also didn't spot that I needed to reboot, meaning that just logging out and in again would not have left me with a consistent system. Not sure if this can be classed as a bug or a feature. poc
