All The Info

Well, I’m usually not so sensitive, but my friend Marti sent me this and I thought I’d share.

This guy runs in marathons pushing his son in a wheelchair.

I have to admit, I got misty for a second.

Barbara Striesand dropped the F-Bomb on a audience member Monday night.

Though most of the crowd offered polite applause during the slightly humorous routine, it went on a bit too long, especially for those who just wanted to hear Streisand sing.

“Come on, be polite!” the well-known liberal implored. But one heckler wouldn’t let up. And finally, Streisand let him have it.

“Shut the (expletive) up!” Streisand bellowed, drawing wild applause. “Shut up if you can’t take a joke!”

Barbara needs to realize if she’s going to do lame political comedy she better expect to get heckled. She’s the one that used the f-word, so looks like Barbara’s the one that ‘can’t take a joke’.

crontab is a scheduling system available on most linux distributions

Sometimes users will create cron jobs that will slow a server down. Access to cron can easily be restricted to all users but the administrator by editing /etc/cron.allow

If, for example, root and only one person (with username user) should be the only ones able to use cron just put root on one line and user on another in /etc/cron.allow.

Note: If cron.allow exists only users in the file will be able to use cron.

To a Windows user the Linux Directory Structure can seem very foriegn. Here is a quick synopsis of the standard top level Directory Structure on a standard Linux box.

/ : The top level directory in the system. This is often called the root directory, because it is the ‘root’ of the filesystem, though there is, in fact, a /root directory.

/bin : The home of binaries for your system. The /bin directory is in the PATH environment variable by default, meaning that any executable file in this directory can be executed merely by entering the file name at the command line - provided you have executable permissions.

/boot : Contains files necessary to boot your system. These include the kernel image and system.map.

/dev : The dev directory is the top level of device abstraction in Linux. This is where each device filesystem will be mounted from. Interfaces to your hard drives, cdrom, mouse and sound card are all found here.

/etc : Most configuration files in Linux are contained in the /etc directory. This also houses startup scripts.

/home : The home directories for each system user. A user is placed in /home/ when logging in.

/lib : Default location for Library files shared throughout your system, although libraries can be stored in any directory as long as it is added to /etc/ld.so.conf.

/proc : Another abstraction directory, /proc contains information about the processes on your system.

/root : The home directory of the root user.

/sbin : Contains additional system binaries, most of which are admin tools. You’ll need to be logged in as root to run many of these files, although you may be able to run them by explicitly specifying the path (/sbin/ifconfig).

/tmp : The temporary directory.

/usr : The /usr directory contains subdirectories that will be used system-wide by all users. These may include binaries, libraries, man files, and other user resources. This is also a good place to add new applications. When updating the operating system it is much easier to peruse /usr for applications than search the whole filesystem.

/var : Contains the variable data that’s always changing as the system runs. This directory contains logs files, mail directories and printing spools.

In linux, disk space that’s used as memory storage is called swap. Typically you would setup a separate disk partition as a swap partition, but from time to time it is convenient to add swap to a running system. (creating an additional partition generally requires a reboot)

A swap file can be created with the following commands:

dd if=/dev/zero of=/extra-swap bs=1024 count=1048576 # create a 1Gb file
mkswap /extra-swap 1048576 # format the file as swap
swapon /extra-swap # start swap file
