LibreOffice/OpenOffice Impress Thumbnails Disappear in the Slide Notes Views

PROBLEM

If are a power user of LibreOffice/OpenOffice’s Impress application you may find bugs from time to time. In this instance, I was trying to change out a Master Page template with a newer one and all the sudden I go to my Slide Notes view and notice that the thumbnail is gone from that view. It’s on other pages with a different Master Page template, but not on one.

It looks like this…

libreoffice-slide-notes-thumbnail-disappearing

SOLUTION

  1. First you create a new Master Page template.
  2. Then edit it to mirror the original Master Page template that is missing the thumbnail.
  3. Then apply the New Master Page template to your desired slides.

Poof… like magic it should add your thumbnail back in your Slide Notes.

Yes this is a less than ideal solution, but at least it works. I’m still trying to narrow down the cause, then I’ll submit a bug report to the open source project.

TUTORIAL: Rapidly Deploy cakeStrap (CakePHP + Twitter Bootstrap) on OpenShift Online

DISCLAIMER: I work at Red Hat and I really love Open Source and Red Hat‘s OpenShift platform!

 

A LITTLE BACKGROUND

I’m a big fan of the Twitter Bootstrap front end framework, and I really like PHP MVC PHP frameworks like CakePHP or CodeIgniter. Recently I was starting an open source QA app for eLearning developers and I wanted to combine CakePHP + Twitter Bootstrap. I stumbled across Hugo DiascakeStrap project. Bingo!

Next, I’ve stopped setting up Rackspace Cloud Servers as development servers. It just takes too much time to setup a server, install the desired environment, and keep it maintained. Plus, OpenShift is a kickass, open source platform for developers to rapidly deploy popular development environment (Java, PHP, node.js, Python, Ruby, etc…) without the hassle of setup and maintenance.

 

MY CHALLENGE

OpenShift has a quickstart example for easily deploying CakePHP within minutes, but that wasn’t easily working for cakeStrap. My challenge was to be able to rapidly deploy cakeStrap on OpenShift so I created a new GitHub project: cakeStrap-example.

 

HOW YOU CAN RAPIDLY DEPLOY CAKESTRAP ON OPENSHIFT

1. Create  and confirm your FREE OpenShift account

2. Click the cakeStrap QuickStart: https://openshift.redhat.com/app/console/application_types/quickstart!13931

3. Configure your app for deployment

  • Enter a Application name and Namespace (the name space will be used for future apps as well)
  • Click the Create Application button

openshift-cakestrap-03

 

4. Wait about 60 seconds…

5. Poof… your cakeStrap app is setup and you have a simple user registration/authentication systems setup already

6. Click on the URL and register to create a user

This should get you started. Let me know what you think or if you hit any issues please report them.

RHEL 6 / Fedora Error: Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.

Rhel-6-full-hard-disk-error-gnome-power-manager

So I filled up my RHEL 6 hard drive this weekend and didn’t clean it up before shutting it down.

ERROR:

Upon booting up I received this error, “Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator.”

 

SOLUTION:

  1. On Login Screen, press Control + Alt + F2
  2. Login as root or sudo
  3. Remove some files or folders
  4. Check the permissions on your /tmp folder or just set them to: sudo chmod 0777 /tmp
  5. Execute the command: reboot

 

Hope this helps someone else along the ways.

 

 

LearnDash: Morphing WordPress into a Learning Management System (LMS)

I’m pretty psyched to get my hands on a new WordPress Plugin called: LearnDash. It is supposed to allow you to convert your WordPress installation into a WordPress Learning Management System (WPLMS).

I’m most excited about ability to sell courses and utilize the Tin Can API features. Its being released 1/28/2013.

Check out the full list of features here and/or signup for update.
