Pick your favorite of gzip, bzip2, xz or lzip (I recommend lzip) and
then:
mount USB-3 /mnt; cd /mnt; lzip *

The archiver you chose will compress the file and add the appropriate
extension all on its own and tar will use that (and the file magic) to
find the appropriate decompresser when you want to extract files later
(you can use `tar tf' to test if you want).

The dependencies on python2.7 are being added by the mozcoreconf
eclasses.  The firefox requirement is in eclass/mozcoreconf-v6.eclass,
spidermonkey has essentially the same thing but in -v5.eclass

You're probably looking for the --no-mtime option. Depending on what
you're using to sort your local videos you can always just tell it to
sort by ctime instead of the (probably) default mtime. Several other
file download programs set the mtime to the last-modified header or
similar, but they tend not to touch the ctime.

What does your /etc/runlevels/ look like? Is the openvpn service in one

Also check /etc/rc.conf and try setting rc_depend_strict="NO". I do wish

I don't have any particularly concrete ideas because the error log isn't
very descriptive, but I have several things you can try that will give
us more info/may help pinpoint the issue.

You might want to post the contents of your /etc/asound.conf and your
~/.asoundrc as well as maybe checking the contents of /usr/share/alsa if
there's anything still referencing pulseaudio in there. Maybe also a
qcheck media-libs/alsa-lib to check if any of the default config files
have any changes in them (you can also diff the output of qlist alsa-lib
and find /usr/share/alsa).

You might also want to check your mpv.conf if you have change any of the
audio settings there.

You can try running mpv in verbose mode (-v) to see if that prints any
more relevant information and also try using any of the other (alsa)
audio-devices listed by --audio-device=help. You could also try setting
--audio-samplerate=48k and try enabling/disabling alsa resampling with
--alsa-resample=yes/no.

mpv's verbose mode will probably give more info as to why it's trying to
open alsa, but I don't know enough about jack to give any useful ideas
here.

What samplerate does that generate sound at? 48k or 44.1k?

Just a note here, if you put the command in your .xinitrc removing and
re-adding the device will probably reset the settings, but the
xorg.conf.d approach should be permanent (works for me without issues).

You can take every option settable through xset and set it in
/etc/X11/xorg.conf.d . That will then make sure the options are set
every time X starts. You can also take the xset command and write it
into ~/.xinitrc if you don't have root.

I have a 05-mouse.conf containing:
Section "InputClass"
Identifier "Kingsis Peripherals ZOWIE Gaming mouse"
MatchIsPointer "on"
Option "AccelerationProfile" "-1"
EndSection

You can look for the xorg.conf variable names you need in xorg.conf(5),
or just google it.

I have had similar issues, but gcc 6.4.0 isn't the (sole) reproducer.

I have 2 systems, a haswell laptop and a Ryzen desktop.
Palemoon works fine built using gcc 6.4.0 on the laptop.
On the desktop, however, I had regularly occurring segfaults that
occurred whenever I ran palemoon and had the ulimit for core dumps set
to 0 (ulimit -c to any other value and the segfaults would not occur). I
managed to "fix" the segfaulting by compiling palemoon with CFLAGS="-O1"
instead of "-O2".
I never tried reproducing with an older gcc or clang as the issue only
popped up when I rebuilt my desktop for the Ryzen CPU (switched from
Nehalem where everything worked fine).

Another person I know who uses palemoon on Gentoo has also had no issues
with palemoon built against gcc 6.4.0 on an Xeon with Haswell
architecture.

I assumed this was an issue just with my machine since I could not
reproduce it anywhere else. It might be that palemoon has issues with
certain optimizations/instruction sets that are aggravated by using
newer gcc versions (which could turn on optimizations by default etc).

I tried checking when/why the GCC_SUPPORTED_VERSIONS was added to the
palemoon overlay ebuilds, but can't find an issue or commit introducing
it (didn't spend that long checking), but if I'm not the only one
affected by this it might be worth it to open an issue with upstream.

If you are on Ryzen (or potentially any architecture that isn't
Nehalem-Haswell) you could try seeing if it's the same issue I
experienced (testing with `ulimit -c unlimited', recompiling with -O1),
otherwise you could try out the ebuild I maintain at [1] which may have
some differences from the one in the palemoon overlay.

Palemoon builds fine with gcc 6.4.0 (just not with gcc 7.2.0), if the
ebuild you're using requires an older gcc it's either wrong or doing
something weird.

Capabilities are a method of providing programs with more or less
specific "privileges" as an alternative to running the program as
root/suid. The "caps" useflag controls these at runtime by allowing
programs to drop capabilities that the program doesn't need so that if
something happens it has the ability to break less things. The
"filecaps" flag is the "equivalent" of the suid bit but for specific
capabilities (so instead of providing ping with suid-root you can give
it CAP_NET_RAW only).

It is almost always better to enable both of these where possible since
it helps decrease the attack surface for the programs in question.

Read capabilities(7) for more information.

That's just part of the inputrc, mine at least also has several settings
set at the top of the file. According to readline(3) the inputrc can
contain both key bindings and variable settings, the lines you pointed
out are the keybindings and what you wanted to add is a variable setting
(set editing-mode vi).

Readline is customized by putting commands in an initialization file
(the inputrc file). The name of this file is taken from the value of the
INPUTRC environment variable.  If that variable is unset, the default is
~/.inputrc. If that file  does not exist or cannot be read, the ultimate
default is /etc/inputrc.

You can use GNU coreutil's `cp --reflink=always'.  This will, however,
only work on filesystems which support the operation (afaik so far only
btrfs). Though other CoW filesystems (such as ZFS) have similar
capabilities with snapshotting.

The only other possibility I know of would be creating an lvm partition
for that file and using lvm snapshots.

You should also be able to implement the functionality via fuse on top
of an ext4 base if the other solutions aren't to your taste.

You want to use the command= option in the .ssh/authorized_keys file for

As far as I'm aware it's based on ip-route(8) syntax separated by newlines.

There's a complete documentation file for netifrc in
/usr/share/doc/netifrc-/net.example[.bz2]

You'll probably be most interested in the "INTERFACE HANDLERS" section
and potentially the "Advanced Routing" section.

You probably only need to list the peer address on a single line and
then that peer should become routable.

No, ecryptfs is a stacked filesystem (filesystem layered on a filesystem)

cryptsetup does encryption on the device layer on a block-by-block basis

You put ecryptfs on a filesystem, you put a filesystem on a dmcrypt
device.

The patch was applied to the initscript, but the ebuild was not
revbumped. You'll have to reinstall the package to get the new
initscript. You can rebuild all packages that use /sbin/runscript with:
`emerge --oneshot -av $(grep -l '/sbin/runscript' /etc/init.d/*)'

It doesn't. As long as you have mpv built with +lua it ships with the
youtube-dl hook which will run youtube-dl (if installed) on any url
passed to mpv, parse the json output and then play the "real" video url.

There's probably around a bazillion addons for that. A quick search
found [1] [2] [3] [4]. Though binding an alias to `mpv $(xsel -b)' and
then executing that after copying a url shouldn't be that hard.

IMAP itself does not have a concept of "Trash", the creation of such a
mailbox is the prerogative of the client (unless the server itself feels
that the imap client doesn't know what it's doing and moves deleted
emails into a different mailbox; not that I've ever seen a mail server
do that), therefore changing the locale on the mail server won't help
and it is indeed something on the client that needs to be changed.

I had a similar issue on one of my computers. Running `emerge -1

Only happened on one of my computers and increasing backtracking didn't

The idea is to create a bridge device, and then bridge the guests
tun/tap device with the bridge and your ethernet device. This way they
all appear transparently on the network.

The net config on that website should be fine for the host, and then
pass these command options to qemu
-device virtio-net-pci,netdev=hn0,mac="52:54:00:12:34:56" -netdev 
bridge,id=hn0,br=brkvm

You can change the mac address to your liking.

Oh, and even that's not easy.

Finding and creating a whitelist that ensures necessary stuff gets done
without allowing people to bypass blocks is almost impossible. Getting
around these sorts of blocks isn't a matter of theoretical possibility,
it's a matter of someone putting in enough time and effort into
bypassing it. If you don't have complete control over all devices all

The only way to blacklist facebook would be to create a whitelist and
drop everything not on said whitelist.

If you block DNS, they can use a different DNS server. If you block IP
addresses they'll use a proxy/vpn. If you use deep packet inspection
they'll use TLS or a VPN or an SSH tunnel.

If you can control the systems so that they don't do any of the above,
it's possible but you've admitted that you can't (unless you can
control all the Virtualbox instances).
