Learn a simple technique that will enhance any color photograph using the free graphic editing software, The GiMP. We're also pushing our Canadian viewers to get their ballots in for a brand new Brother MFC-J615W all-in-one printer, answer a lot of viewer questions, and welcome back rdstreets following his open heart surgery.

Notes:
With Doug's issue with Ubuntu, it wasn't mentioned, but it could be caused by a bad ISO download or botch CD burn.  Check the MD5 on the ISO and make sure it matches the site's reported MD5 for the ISO, and then try re-burning the CD at a slow speed.  Ubuntu also lets you test your CD upon boot; just choose it from the initial menu when booting from your install CD.

If you want to secure up your apache file sharing, look into htpasswd which will allow you to add password protection to your apache server's folders.

Topics Covered:

  • Congratulations to John (our Director / video guy) and Christy (former co-host and news anchor)!  They were married to eachother on Saturday.
  • Justin.TV experiences some issues which cause the feed to lock up momentarily.  A strange monster voice comes from Robbie as a result, but it quickly is resolved.
  • Twitter understands what you want to do, but doesn't wanna do it.
  • Eric gets reprimanded by Robbie for not tweeting.
  • Welcome back to Robert Streets (rdstreets in the chat room) who was away following open heart surgery.
  • Tali (Robbie's daughter) lost another tooth, and you'll never guess how.  We'll give you a hint: she's too young to lose a tooth naturally.
  • Viewer Question:  I installed Ubuntu 10.10 on a 900 MHz computer with 128 MB RAM.  I get to the welcome screen / password prompt, but when I try to login, it fails and just takes me back to the login screen.  What can I do to fix this?
  • Viewer Comment:  Pitivi works well to convert gtk-recordmydesktop files to other formats.
  • Tongue-in-Cheek Side Note:  If you spell things correctly in your email, it will help Eric sound like he knows what he's talking about.
  • Viewer Comment:  I know Robbie likes Star Trek, and I came across an old-style TOS Communicator device that runs off a computer's USB port.
  • If a device says "Compatible with Windows and Mac OS", it doesn't necessarily mean the device won't work on Linux.  It usually just means they didn't test it on Linux, or the company simply doesn't want to have to furnish support calls for all three systems.
  • Viewer Comment:  I can have anything made in China.
  • A bit of behind-the-scenes: We show you John's chatroom teleprompter.
  • John is now the Director of Category5 TV, and loves having "cool stuff" surrounding him.
  • Viewer Question:  When is Bekah's (Robbie's wife) due date?
  • Viewer Comment:  Deep Space Nine for the win!
  • Viewer Comment:  Voyager for the win!
  • Top Stories from the Category5 TV Newsroom.
  • Discussing our thoughts about the "hacker" kid who has been charged with hacking his school board's web site.
  • Prize Qualifications:  Win an MFC-J615W all-in-one printer from Brother Canada and Category5 TV!
  • Feature:  A simple tip that will let you enhance any color photograph using free software.
    Before and After

  • Duplicating photo layers in the GNU Image Manipulation Program (GiMP).
  • Creating a Gaussian Blur effect in the GiMP.
  • Changing the layer mode to overlay in the GiMP.
  • Desaturating a layer in the GiMP.
  • Creating a new transparent layer in the GiMP.
  • Using the eliptical marquee to add a dark shading border to your photograph, enhancing the subject of the photo by drawing your eye to the center of the photograph.
  • Feathering your marquee selection in the GiMP.
  • Working with layers lets you experiment without eliminating your ability to go back.
  • Changing the opacity for your layers in the GiMP.
  • Viewer Question:  I work at a school as part of the IT team, and have been able to improve our productivity with the help of Ubuntu and Category5 TV.  We are increasingly using mobile devices to access our data.  Is it possible to allow our users to access the shares via a web-based interface?
  • Updating your apt repositories using the sudo apt-get update command.
  • Using the php5 meta-package to setup an apache server on your Ubuntu Linux computer.
  • Installing applications in Linux using apt-get.
  • Testing your apache / php5 installation to make sure the install worked.
  • Pointing the apache Document_Root to the proper location so your files will be shared through http.
  • Editing /etc/apache2/sites-available/default (your apache server's default configuration) with nano.
  • Some quick security mentions about doing apache-based file sharing over http.
  • Robbie's 5-year-old broke the Spongebob DVD.  What's Eric's excuse?
  • John's mic begins farting.
