Get your hands on it and see what it is all about. There are a lot of interesting things on FFH2 that are intrigueing like a new Gnome and GTK+ and updated kernal and lots of new Debian packages. I might try it myself! below are the links to the ISO's.

Command Line Command of the week - free

This command gives you anything you want for free!! Wow, Linux is soo....what's that you say? Oh, I see....This just gives you the amount of free memory in your physical memory and swap drive? Oh, buffers too? The -b switch displays the amount of memory in bytes; the -k switch (set by default) displays it in kilobytes; the -m switch displays it in megabytes; the -g switch displays it in gigabytes. How nice:[

And, finally thanks to Art for providing a possible solution for getting FreeNAS and Ubuntu to work together. Art was unable to listen to mp3's or watch DVD's from content stored on a FreeNAS server. So he wrote a post on a Sourceforge forum and there might be an answer to his post by now. I haven't checked yet but it is worth a try if you are experiencing problems with the same setup. Here is the link.


Well, that does it for me! Thanks for visiting, have a good one!

Oh and by the way if you are on another VoIP network that supports SIP you can reach me by this SIP Number. This will only work with networks that are SIP compliant. I am not sure if this will work with Skype, but give it a try. Visit this link first- then try this number 17470454941. Also, check out Gizmo and see if it fits your needs. I don't make any money on this, the service just appeals to me. Bye.

The Gizmo Project and Wildcards

Hi everyone!!

Sorry for the short podcast, just too many things going on this past week. This week I introduce you to the Gizmo Project which is another Voip product similar to Skype. The reason why I like it is the free voicemail feature that they offer you. Also, it gives you and option to record your conversations easily for free!!! For a podcaster that is valuable. This was supposed to be the first installment of the linux equivalent segment, but I was just too excited to tell you about this to offer a real "equivalent". Yes I know Skype is available for linux but I think gizmo is a good alternative to Skype. I am astounded by its feature set that they offer for free. I'll try harder next time to get out a better windows equivalent package.

I also explore wildcards. You may be already familiar with the asterisk (*) which can represent any number of characters. Below is a list of wildcards and proper syntax. Enjoy!!

The asterisk (*) - used for any number of characters. It can be used like this:

ls *.txt

This will list all the text files in the current directory.

The question mark (?) - used to denote a single character. It can be used like this:

ls p12000??.png

This will list all png files (it's a graphics file good for websites) that start with p12000 as shown before the question marks, but the question marks are a place holder for any character at the position where the wildcard is placed.

If you wanted to find a file which contains a letter or number form a specific subset you could use the square brackets, []. For example:

rm fresh[k,x]ubuntu.txt

This will, of course, remove any text file freshkubuntu or freshxubuntu. But why would you want to do that??

You can also use the brackets for contigiuous sets of letters or numeral, such as, a-b, or 1-9. This is shown below:

copy vacation[a-c]200[0-6].* /home/harlem

As you can see, wildcards can be mixed to give even greater flexability to your commands. Now don't fall asleep on me, I just have a couple more to go!

You can also use the brackets to limit your search by eliminating letters that a file does not contain by introducing an exclamation point after the first bracket and before the first letter, like:

ls [!fresh].pdf

This command will only show files that do not contain the LETTERS f, r, e, s, h, and inadvertently the word fresh. You can do the same to a range of letters, such as, a-w.

What if you wanted to search for a file that has a specific word in it? Well, you would use curly brackets, {}. Its not apparently intuitive, what with all the square ones dominantly in use. For example:

mv {fresh,ubuntu,is,the,best,podcast,ever} /home/toptenondigg

This finds files with the words in the given subset and moves it to the appropraite directory.

Note - These wildcards can be used with a number of commands, not just the ones listed here. Remember, use caution when moving things around with wildcards. Just be safe and if you are at all unsure about what you are doing stop and think about it. That's it for now, see you next week.

Four letter Words

Download Episode 23

Hi, I am back!! This week I talk a little bit about root and sudo and how that is used in Ubuntu. Just a couple of things about it, firstly, that the root account and hence the ability to use a root terminal is turned off by default. You can however turn this feature on at your leisure, though not recommended. In any case, root as you may have heard on the podcast is like an administrator account in Windows. This account can do just about everything to your computer that you would want it to do and some things that you might not want it to do. Again, it is powerful, but, alas not idiot-proof. This is where sudo comes in. Sudo is a command line command that begs for a little more attention than the usual command line command of the week. What sudo does is allows the user with your regular run of the mill permissions to do administrative tasks. Things like edit configuration files, setup file permissions, and download..um...packages, yes, to install on your system. The way I see it as explained in the podcast root is to sudo as Superman is to Clark Kent. Either way, both have the same weaknesses and that is kryptonite, or incorrect command line input. See, Superman isn't so BAD after all. For the regular user, you might never have to access a root account. I'll be honest with you I haven't even tried. But, one never knows when I have to rip off my button down shirt to reveal my Superman footie pajamas (don't be jealous, I got them for Christmas!) Well, there you go, just a couple things about root and sudo and pajamas, hmmm. Here is a link to more informatioin about root and sudo:


This weeks CLCOTW: wc - Counts word (among other things, check the man pages) in various files.

Pretty handy to have around if you are the obsessive/compulsive type that has to know how many word you type...97..98..99...excuse me. You can also find out how many characters and bytes if you want. From the screenshot, I wrote 1721 words in my preparation for this episode, wow, not bad!! I hope this helps someone!!!

Here is a great tip from Steve B., he recommends a package called Yakuake for all you command line geeks. I downloaded it and it does run on gnome as well as kde. Knock yourself out. See screenshot below.

See you all next week!!
