Do The Evolution by downrodeo

This is a t-shirt design by my buddy Alan that he had submitted to Designs by Humans, an online t-shirt store recently.

The design “Do The Evolution” depicts the skateboarding scene during the 80s and 90s. I love the concept, being a  skateboarder my self during the 90’s, My crew always ran into issues with the authorities. We fought back every single time and won a few battles. Then, came along X-games, made all our hard work seem like a waste of time. Extreme sports suddenly seemed like the “IN” sport. Why? Tv coverage and the chance to host international events. 2 major contributors to our tourism industry.

On the bright side, this once negative sport is now widely accepted and as a result more participation can be seen. Parents love it as it is helping keep their kids away from drugs and negative social activities and in return leaving a an active lifestyle.

Ok, back to the design. If you like it then please drop a vote at Designs by Humans for Alan.

Extract rar files in Linux

RAR is a proprietary compression format widely used today. It’s supposedly has 30% higher compression rate when compared with WinZip. If you download large torrent then chances are you are are already well acquainted with RAR.

I use RAR on my Windows and Linux boxes everyday and today I’ll show you how to extract RAR files from the Linux command line.

In Linux, to extract a RAR file you would use the unrar command. The unrar binaries are typically not included with the default Linux install so you will have to install them either through the package manager or by downloading binaries from rarlab.com

Let’s get to the HowTo now,

Extract a RAR file into the curren directory.

# unrar e [filename].rar

Extract a RAR file with the full file path.

# unrar x [filename].rar

List contents of a RAR file

# unrar l [filename].rar

Test intergruty of a RAR file

# unrar t [filename].rar

If you face any problems obtaining,installing or using unrar please contact me. I will be glad to help.

Automount

Decided to drop my permanent mounts and go with automount instead. Why? Well I don’t access those folders all the time, they are mainly for backup so mounting only when I need them seemed like a better idea.

I modified the /etc/auto.master file and created a new file named /etc/auto.nosebleed. Contents shown below.

# auto.master file

/mnt/nosebleed /etc/auto.nosebleed –timeout=60 –ghost

# auto.nosebleed file

mp3 -fstype=cifs,rw,noperm,guest ://10.0.0.200/Mp3
ebooks -fstype=cifs,rw,noperm,guest ://10.0.0.200/eBooks
movies -fstype=cifs,rw,noperm,guest ://10.0.0.200/Movies
scratch -fstype=cifs,rw,noperm,guest ://10.0.0.200/Scratch
software -fstype=cifs,rw,noperm,guest ://10.0.0.200/Software
tv-shows -fstype=cifs,rw,noperm,guest ://10.0.0.200/Tv-Shows
videos -fstype=cifs,rw,noperm,guest ://10.0.0.200/Videos

My options,

–timeout=60 will set the ideal time for the mount. If there is not activity for 60 seconds the path will be unmounted.

–ghost will enable the user to see the mountable directory without mounting them.

Free Software Sticker Book

Yes, free.

I have searched for something like this for a long time and now thanks to Ravi I found it.

Free software sticker book from PIKAO.ORG. The book is licensed under the MIT license There is no limitation to what you can do with the book. Print,use,copy,merge,publish,distribute, sub-license or even sell it.

If you design stickers of your own, you can submit them to stickers@pikao.org. Your stickers will then be included into the sticker book as part for the free sticker book project.

Why do I want stickers?

I have so much real estate available on my nb covers and my desktop towers. I hate to see them plain, I already have a few stickers on them like Ubuntu, Linux and few others. Now I get to fill the space up with even more meaningful stickers. No designed for WinXP / Vista stickers.

I would love to distribute free CDs and stickers moving forward. All in the name of opensource.

Do you want free stickers?

4 easy steps to get you sticker(s). Make sure to download the book first.

  1. Remove the current sticker on your computer.
  2. Print the sticker you like from the book.
  3. Cut sticker(s) out.

Mounting CIFS shares

I was playing around with Samba and CIFS mounts last night.

I needed to mount a directory on my openSUSE 10.2 box to my samba server where all my mp3 are stored. Since smbfs will be dropped soon I decided to go with CIFS. Note, smbfs will depreciated starting with kernel version 2.6.20.

There are 2 ways to mount, examples below.

The first method shown below is normally used for temporary mounts. Mounts will be discarded upon reboot or execution of the umount command.

mount -t cifs -o rw,guest,noperm //10.0.0.200/Mp3 /mnt/mp3 umount

/mnt/mp3 (this will unmount)

If you are looking for a permanent mount, you will need to add the following line into your /etc/fstab file.

//10.0.0.200/Mp3 /mnt/mp3 cifs rw,guest,noperm

Options I used for my mounts,

rw – read write access. My shares are public so everyone has read/write access.
guest – no password prompt.

noperm – client does not perform permission checks. Needed if uid and gid are not the same on client and server.
