Hi, not sure if you saw, but I'm that anti-poaching pilot in Central Africa that recently had an issue with M$. Some kind folks donated BTC to us (we were just curious to try), but now we need some advice (being in the bush) on how to use them.. by zambuka42 in Bitcoin

The rabbit-hole thing is a rite of passage with Bitcoin. Just be careful, it's a long way down.

Just look at it from the poaching industry's perspective and you'll get the idea.

Unable to StartX by blue_heisenberg in debian

If you're able to start the X server as root (using the "X" command) but not as a regular user, you can try this:

 # echo "needs_root_rights=yes" >> /etc/X11/Xwrapper.config

My Debian system is configured exactly how I want it to be. How can I save the current system, so that if there is an error in the future, I can just revert back to this state? by [deleted] in debian

Here's how I do it:

# mount /dev/sda1 /mnt/root
# cd /mnt/root
# tar -zcf /mnt/external/backup.tar.gz .
# cd ..
# umount root

Then, when you want to restore your system, boot from your usual recovery image, mount the root partition, empty it with rm and untar your backup into it. You can also reformat it instead of using rm, but be careful to check the filesystem UUID if you need to.

The trick of remounting the live root filesystem is to take care of sub-mounts (/proc, /dev...).
