comment What speed should zsh connect to tmux at?
I'm pretty sure these old baud settings persist just for backwards compatibility reasons, and don't actually control anything anymore. I'm quite certain zsh doesn't care.

comment Having an independent console to kill rogue process?
This doesn't answer your question, by I suspect Flash is only able to cripple your system like it does because it eats enough memory to cause your system to start swapping. If you can get away with it, turn off the swap and let the Out-of-Memory killer do its job while your system is still responsive. Barring that, buy an SSD if you haven't already.

comment Grep multiple pattern negative match
I did some more testing, and found that if there is an empty line in the patterns file it will match every line, causing no lines to be returned with -v. This isn't a problem with -F however, and -F might speed up grep for your task - might be worth trying for you.

comment Grep multiple pattern negative match
When I tried this on my system, grep -v -f had the desired behavior, only returning lines that matched none of the patterns. This was with (GNU grep) 2.14.56-1e3d. What grep are you using?

comment sshfs and Emacs: file changed on the disk
This doesn't answer your question, but I suggest you use Emacs's TRAMP mode instead of sshfs. It's more flexible, and is likely to be faster after setting up the initial connection.

comment Create SSL certificate - Silent
Your "normal way to create the certificate" doesn't prompt for any data. Are you not wanting it to output anything? Then use 2> /dev/null.

comment Why is Ruby using 100% CPU in startup?
Is this a EC2 micro instance? Amazon severely constrains the CPU time those instances can use.

comment Set executable heap
I don't think the old architectures would behave that way, the underlying hardware has no way of knowing what memory pages are mmap'ed executable files and which are meant for heap space, unless it is told. Architectures that don't support something like the no-execute flag on pages will always have executable heap, for others, the kernel is the only limitation.

comment get age of given file
@terdon Both. That Q&A you link is correct, current filesystems have been tracking the creation time for a while now. In FreeBSD, you can actually get at this from stat, in Linux the syscall has not been reworked so you have to resort to hacking with debugfs.

comment How do I stop sed from adding extra newline characters
I don't know how to make your AIX sed behave, but head -c -1 can bite off the final newline.

comment Open 2 instances of the same program
You can set the DISPLAY environment variable instead of using -display, all X11 programs should support this.
