Re: [PLUG] VLC 3.0

[Tomas K]

Thanks Galen,

I believe that my lack of awareness of it is total indifference to 
any eye candy gimicks in UI. All I care about is practicality and
effectiveness of the interface together with good ergonomic. My hands
hurt with mouse and I hate distraction from the task at hand.

For that reason, I do not even know what to look for and it would not
surprise me if it is currently active on my desktop. I am quite
familiar with Knoppix and I still have no idea - I guess if it does not
have label or command line form - then it does not exist in my mind.
Well, since I am not aware of it, it must be good UI element - not in
the way of anything, not distracting me from writing this.

If I remember, I will ask you some day to point finger at it and show
me.

:-) Tomas

Re: [PLUG] Rsync error that I don't understand

[Thomas Groman]

It is saying some sort of IO error occurred when trying to get the
current working directory. If you have already made sure that directory
exists you should check the consistency of your disks. I remember having
similar errors when working with disks with bad sectors and floppy disks.

[PLUG] Ftree Vectorization

[Thomas Groman]

I normally compile my programs with the CFLAGS -O1 -pipe -march=native
-ftree-vectorization. I assumed back when i used GCC version 5 that
because skylake was not an march option yet it would not make full use
of the SIMD instructions on Intel's Skylake generation processors. I
added in the -ftree-vectorization parameter to make the resulting
binaries check if certain SIMD extensions exist and use them. At least i
thought that is what it did.

With GCC version 6.4 is the ftree parameter still necessary? Especially
when -O2 is used. The only reason i used -O1 before was due to a bug in
some software i was using at the time that has since been patched. Also
on an unrelated note is the -mtune parameter redundant if you have
already specified -march?

[PLUG] Rsync error that I don't understand

[John Jason Jordan]

I have a 2-bay Mediasonic that is mounted as "Movies." I have a 2-bay
Synology NAS that is mounted as "Synology." I have an rsync command
that I use to make a backup of the Mediasonic to the Synology:

rsync -rptog --progress --stats --delete
--exclude-from=/media/jjj/Movies/rsync_exclusions /media/jjj/Movies/ 
/media/jjj/Synology

This command worked last time I ran it, but when I ran it just now it
gave me:

rsync: getcwd(): Input/output error (5)
rsync error: errors selecting input/output files, dirs (code 3)
at util.c(1042) [Receiver=3.1.0]

It sort of sounds like something is not mounted, but both devices are
definitely mounted:

mount
192.168.1.115:/volume1/Synology on /media/jjj/Synology type nfs
(rw,noexec,nosuid,nodev,addr=192.168.1.115)
...
/dev/sdd1 on /media/jjj/Movies type ext4
(rw,nosuid,nodev,uhelper=udisks2)

I could use some clues.

I tried all kinds of things, and when I tried e2fsck it said that I
needed to umount it first, so I did. But then, before running e2fsck, it
occurred to me to try to re-mount it and then try my rsync
command again. Voilà! It is running as I write this.

The strange part is that it was definitely mounted, but rsync didn't
think it was, How can something be mounted but not really mounted? Oh
well. Another of life's mysteries that I will probably never grok.
