Using Kino for video capture
by Fred Smith
I know Kino is officially obsoleted by its maintainer, but I have chosen
to TRY using it anyway, since it'll do video capture from firewire, AND
let me see what it's capturing.
So, I've got a bazillion commercial VHS tapes, a considerable number of
them are series of TV shows, so I'm to have to spring the cash to buy
them again in DVD format.
I have a "Dazzle Hollywood DV BRidge", feeding analog signal into it
from the VCR, and digital via Firewire from there to my PC.
I can start up the vcr and watch it play in Kino, and see Kino capturing
the data into files that grow real big, real fast.
My problem is that Kino isn't naming the files properly,... it gives
a basename, the date, the time, and a suffix. The only trouble is, the
times it uses are all zeroes.
That has the un-helpful result of each file overwriting the previous one,
as Kino splits the capture into multiple files, as they all have the
same filename.
I don't see any options in Kino for controlling how it derives the time,
or how it chooses the name, so I may not be able to use Kino for this
project. (I can try dvgrab, but it's nice to be able to see what it's
doing, at least until I become comfortable with the process.)
Do any of you have any experience with Kino that might help me with this?
Thanks in advance!
Fred

F20 - Can't Select Desktop Environment at Login
by Brian Hanks
I've had quite a challenge getting Fedora 20 to work on any of my
machines, but I have finally managed to work through the issues and I
have it running on two of them. The problem I'm having now is that I am
not able to select the Desktop Environment at Login. In the past, I
have always installed a particular environment, usually Gnome or Xfce,
then added others via yum after the initial install was complete. This
act of adding the second Desktop environment automatically caused a
tweak to Login Badge where I was able to select the desired desktop as
part of the login.
This did not happen this time. After extensive Google searching, I've
been unable to determine how to correct this, so I'm hoping someone can
point me in the correct direction.
Thanks in advance,
Brian Hanks

alias ymu yum?
by Frank Murphy
Due to slight dyslexia
when working on cli.
I can do ymu update #frequently
I used an alias ymu yum,
works as user and root.
sudo ymu doesn't work,
I have placed alias sudo="sudo "
in home /.bashrc
still no joy
Have checked Google for sudo alias (expansion)

is "groupmems" not being setgid worth a bugzilla report?
by Robert P. J. Day
on my f20 system, perusing the account-related commands and ran
across the "groupmems" command, whose man page reads:
"SETUP
The groupmems executable should be in mode 2770 as user root and in group groups. The system administrator can
add users to group groups to allow or disallow them using the groupmems utility to manage their own group
membership list.
$ groupadd -r groups
$ chmod 2770 groupmems
$ chown root.groups groupmems
$ groupmems -g groups -a gk4"
currently, /usr/sbin/groupmems has the following properties:
# ls -l /usr/sbin/groupmems
-rwxr-x---. 1 root root 56960 Jul 26 2013 /usr/sbin/groupmems
#
so how should i interpret the man page? should groupmems be setgid?
or is the man page suggesting how the reader might set it to setgid
for further customization? the way the man page is worded seems
ambiguous.

Best practices for SSD
by Wade Hampton
Is there a current best practices for use of solid state disks with
Fedora 20? I found an older doc for Fedora 14 and also the Red Hat 6
deployment guide, but both don't have a lot of details.
I have a laptop and am installing a 120G SSD. Also I plan on
updating an old CentOS server with a single 120G SSD (CentOS 5.10).
Some of the recommendations I have found:
- partition on a 1M boundary
- use native partitions, not LVM (for TRIM)
- mount using relatime (or noatime for CentOS 5)
- mount using discard (or use the fstrim program periodically)
- use EXT4
Other recommendations I have seen recommended:
- move some temporary files to tempfs
- move /tmp to RAM: /etc/fstab
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
- change I/O scheduler by adding "elevator=noop" to boot parms
- reduce swappiness: /etc/sysctl.conf
vm.swappiness=1
vm.vfs_cache_pressure=50
Thanks,

Creating multiple BTRFS partitions
by sam tygier
Hi,
I'd like to install with an encrypted /home, but unencrypted /. I would also like to use BTRFS.
Currently if I try to make 2 BTRFS partitions anaconda actually makes 1 partition with 2 subvolumes. This means they will share encryption options. I think this is because anaconda considers BTRFS to be a 'Partitioning Scheme' rather than a partition type.
I also tried creating the root partition in gparted, and selecting it in anaconda, but I am told "You must create a new filesystem on the root device".
The other work around I though of would be to create the partitions as ext4, and then convert them after, and then defrag and rebalance. But that seems pretty inefficient.
Any other ideas?

CentOS on home machine HD
by Roger
I've not experimented with server systems for many many years so would
like to understand a few points.
On my home machine I have 2 hard drives one has 2 partitions, Ubuntu on
the first and Fedora which I use most on the second partition.
the pc boots through the Ubuntu grub.
I have Fedora 16 on the second drive but don't use it.
If I install CentOS on that Fedora hard drive with the first drive
unplugged it should be a fresh install.
Questions:
When I switch on the first hard drive and cold boot, I can choose on
bios boot between the centos and nix drives, Centos should not know of
the other's existence is this correct.
As a server, the Centos drive would permit access to 3 ip addresses.
It will have LAMP stack, latest Ruby and Rails and Drupal 7 for development.
Is it possible, while the pc is switched on during the day to use the
CentOS as a server for development without affecting or accessing my
working Linux installations?
Will a thompson gateway TG782T ADSL modem/router be sufficient to act as
a basic server modem for the above proposal.
I hope I've explained it well enough.
I'm thinking about getting something like a HP6200 for a server but want
to learn first before parting with cash.

sound works randomly?
by Tom Horsley
I'm very confused. If I run the gnome sound control,
test speakers works fine. If I run "play", the sound
plays normally. If I run "aplay", I got no sound till
I rebooted, then aplay started to work, but if I run
mplayer or youtube in google-chrome, I still get no sound.
The gnome sound control "Applications" list does
show mplayer or chrome as an app using sound, the
apps don't give any apparent errors, all the
messages from mplayer with all the details of what
it is doing seem to indicate it is talking to
the pulseaudio daemon OK, but there is no sound.
What is going on? Everyone thinks the volume
is cranked up, nothing is muted.
