Mostly, this should fix the issue 70% of the time.","Make sure your dependencies are installed correctly. Error messages help out a lot here! Often it will say shared/linked library not found or something along those lines.","Make sure you sourced build/envsetup.sh.

Again, to quickly jump there, use croot.","Make sure your computer itself isn’t faulty. HDDs usually die first, followed by RAM. SSDs rarely die but failure is not unheard of. In extremely rare cases, your CPU may have a defect. If you're unsure, run a stress test using a program like Prime95.","If something goes wrong and you've tried everything above, first use Google to look up your error!

If you managed to follow along, congratulations!","After you finish building, you can try out the Git Started guide.

Satisfied, you push it up to GitHub.","'''Example 2:''' You bring up a bunch of commits, and squash them before pushing to GitHub.","'''Example 3:''' You intentionally want to pass off another developer's work as your own. You cherry-pick the commit, and then amend the commit to rewrite the author information.","Let's go over why this is wrong. Example 1 is an example of an unintentional kang. You didn't want to resolve the git merge issues, so decided to just copy the code and commit it as your own. This is bad because the author information does not get transferred over with your copy, which you have to specify manually.","Example 2 is more of an accident. If you squash multiple commits, all authorship information for the range of commits is lost. In addition, it becomes a real headache for other developers if something in the range of your commits is wrong. Because you cannot individually revert commits in a squash, squashing is very much discouraged and should ONLY be used when you have a lot of commits that you committed yourself and are small in nature.","Example 3 is an example of an intentional kang.

This is as simple as doing rclone. This does however waste a lot of space. What we can do instead is use qemu-snapshot.","Qemu-snapshot redirects the writes to a new image, so that you can save space. say you have disk.qcow2 you can run the command qemu-img create -f qcow2 -b disk.qcow2 disk-snap1.qcow2 and that will create a new image. Now you modify qemu to use disk-snap1.qcow2 it will read from disk.qcow2 but will never write to it. All modifications made are made in disk-snap1.qcow2. and to revert the snapshot, you can simply delete the disk-snap1.qcow2.","Another use of this is to do qemu-img create -f qcow2 -b base.qcow2 vm1.qcow2&& qemu-img create -f qcow2 -b base.qcow2 vm2.qcow2. by making two separate snapshots, we can now run multiple VMs each with their own unique writable disk, that is based on the base.qcow2. this is great for running multiple VMs without needing to waste space and setup time. REMEMBER writing to the base disk will corrupt the snapshots. It's a wise idea to change the permissions of the base disk to read only, this prevents user error. Even professionals with many hours can slip up and accidentally make an error. Remember to practice safe VM handling.","The above paragraph is about creating external snapshots which is great for when the VM is off, and should be done when you wish to create a new VM. However qemu also supports internal snapshots and live snapshots. The snapshots work internally in the single qcow2 (or qed) image. It may not be as flexible, however it is bother faster, and for many people more convenient and nice to use internal snapshots.","Using the human monitor above it is shown the commands savevm loadvm info snapshots these can be used to save, load and view the current snapshots available. Live snapshots save the entire state of the cpu, devices, Ram, as well as the entire disk contents, so the live snapshots can be a good amount larger.

Mostly, this should fix the issue 70% of the time.","Make sure your dependencies are installed correctly. Error messages help out a lot here! Often it will say shared/linked library not found or something along those lines.","Make sure you sourced build/envsetup.sh. This is especially common and worth suspecting if none of the build commands like breakfast and lunch work. If you have repo sync ed do this again.","Make sure you’re at the root of the build tree. Again, to quickly jump there, use croot.","Make sure your computer itself isn’t faulty. HDDs usually die first, followed by RAM. SSDs rarely die but failure is not unheard of. In extremely rare cases, your CPU may have a defect. If you're unsure, run a stress test using a program like Prime95.","If something goes wrong and you've tried everything above, first use Google to look up your error!

If you squash multiple commits, all authorship information for the range of commits is lost.
