Paranoid pragmatic security type; I helped develop the AppArmor mandatory access control system. If AppArmor isn't a good fit for your security requirements, please consider running TOMOYO, SMACK, or SELinux.

For more information about me, including an abridged book list, see my careers2.0 profile. Or if you're old-school and want to see all my LaTeX skills on display, my old-fashioned resume is also available.

comment How to show overall usage of system resources in linux?
It's a little strange that it starts a daemon, but the data it collects and presents is probably worth it. Thanks!

comment Extract file and folders with specified permissions
To improve upon your second command, find . -type f -print0 | xargs -0 chmod 644. The -name "*" isn't necessary, and xargs(1) will parse filenames on spaces or newlines unless you use the -0 -- which parses filenames on ASCII NUL character, which cannot appear in filenames. The -print0 for find(1) asks it to format its output in a mode suitable for xargs -0 input.

777 is dangerous and only applicable to a very small minority of systems.

Are you over-writing existing files when doing so?

Awesome, many thanks for explaining something I only vaguely recalled and began to wonder if I even imagined it. :)

VirtualBox should have no effect on this; you might have to rely on PARC to give you support on this download since it's difficult for others to even look at it. :(

comment No such a file or directory in linux bash
@Yasaman: I tried to download a copy for myself but they apparently require a signature of some sort before they'll give a username / password. Sigh.

comment No such a file or directory in linux bash
That's amazing: file reports xle is a dynamic executable but ldd can't report the libraries that it requires. ldd requires the program's cooperation but I haven't seen this sort of behavior in a decade. (In fact, I tried to reproduce this exact bash error message a few weeks ago and gave up. Good work there.)

Are you positive /etc/init.d/oracle-xe is supposed to start a web server on port 8080?

comment CentOS 6.1 + Oracle Express 11g
I'm sorry -- none of this makes any sense. Please copy and paste the commands you actually executed, the error messages you actually get, and what you expected to happen. If you're trying to connect to localhost make sure you have a web server of some sort listening on port 8080: netstat -anp for help there.

comment Ubuntu. I have disabled ssh login with root on my server, but how to copy files from local to server now?
Why is the apache tag here? You never mention Apache in the question. Why doesn't scp foo bar baz xyzuser@ubuntu_host:/foo/bar work?

comment Ubuntu on VMWare Player: My Ruby is missing
Were any changes that you made to the system retained? Or were they all thrown away? Does the properties for your virtual machine (or block device?) allow writing to the virtual machine or block device? Do you have permissions to modify the files that hold all the virtual machine data?

comment Install gentoo on macbook pro
This question would be more appropriate for Super User, but it is lacking a huge amount of detail that they would require. Which gentoo live dvd? A recent version? One known to work with Apple's EFI boot process? Or are you using BootCamp? What errors specifically are you getting?
