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). -- Simon Thelen

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.

Have you > tried 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. > The ebuild from the palemoon overlay explicitly checks for the gcc > version and refuses to proceed if it's newer then 4.9.4. I have > wondered why, but now I know. 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.

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. -- Simon Thelen

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.

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 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/*)' This was mentioned in a newsitem draft on gentoo-dev, but as far as I can tell that newsitem was never published. -- Simon Thelen

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. > I woyld like something like: > Click on youtube-url, a window (console) pops up > and starts to watch the video > directly. > > Is it possible somehow?

As I > understand it you need to configure the locale on the mail server. 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. -- Simon Thelen

I had a similar issue on one of my computers. Running `emerge -1 =dev-util/boost-build-1.60.0 =dev-libs/boost-1.60.0' fixed it.

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. -- Simon Thelen

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 time, you might as well just give up. -- Simon Thelen

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). -- Simon Thelen
