comment What happens when you 'mount over' an existing folder with contents?
@DanSheppard That's one reason I like my mount points set chmod 000. Also why systemd fails the boot if critical mounts fail.

comment Is there a way to source an encrypted (GPG) file on-the-fly in a script?
Of course, if you have a worry about someone being able to read a temporary FILE, with this you have the exact same worry with someone being able to read the temporary pipe created by <(command).

comment Can strace/ptrace cause a program to crash?
GUI programs often have a lot of race conditions in them due to sloppy coding. This causes crashes. For example, the program might be sending several commands to X and expecting them to all be complete in another thread or signal handler. They get back an unexpected value and don't know what to do.

comment Why is video tearing such a problem in Linux?
With Nvidia compositing solved the problem for me, when I used to use Nvidia back in 2007. Not in full screen though because full screen windows turn off the compositor, it assumes you're going to run an OpenGL game I think. With Intel, have you tried setting Section "Device" Option "TearFree" "true" in X? It doubles video RAM use but I think it'll work.

Sorry about the late accept. This didn't work at the time I asked the question but I just tried it lately and it does now. Thanks.

comment How does one create a directory that can't be seen and can only be accessed via its absolute path name?
@blazonix: Without a super-user the OS would still need a way to grant unusual permissions. And as Linux found out with capabilities, most of these unusual permissions can be abused to grant all the others. If you can load modules into the kernel you can write kernel code. If you can change file permissions you can overwrite ls with an evil version. If you can make backups you can read private files and try to crack the system password hashes.

comment Which process scheduler is my linux system using?
@TAFKA'goldilocks': but this question totally IS a complete duplicate. Perhaps good answers should be added to the other question instead of here.

@TAFKA'goldilocks': I don't have any control over the closing of questions here as my rep is too low.

comment Is making /var/log directory read only on debian linux safe?
Or adjusting your settings on the log daemon so it only logs emergency and critical level logs.

comment Why does no one use the true Bourne shell as /bin/sh?
The downside is that people write scripts that work on their one system, thinking their script is compatible when it isn't. I once fixed almost a hundred Gentoo shell scripts that actually required bash but called /bin/sh. They all broke when I changed /bin/sh to be dash instead of bash.

comment External Cache not socketed
Pentium 2 and 3 cache was sort of socketed. It was in separate chips that were glued into the back of the slot package.

comment What doesn't need defragmentation? Linux or the ext2 ext3 FS?
The other answers are good but leave out one important bit: All of the filesystems: ext2/3/4 and NTFS will fragment files quite a lot when low on disk space. If you want to prevent fragmentation, don't allow your filesystem use to exceed 90%.
