I was installing some tools on my mac today which I wanted to have in the path. Specifically I was installing the Android-SDK tools. I wanted to have the adb shell come up no matter which directory I was in. Being a Linux guy I check out /etc/profile but discovered that mac does it just a tiny bit different . Below I will show you two ways to edit your path in mac OSX. One is permanent and one only lasts until reboot.
A few weeks ago I wrote a article on disabling the caps lock key in Windows. I decided since I have been writing some Linux articles I may as well show a way to do the same thing in Linux. Its a short, quick fix but it can be useful if you hate capslock like I do.
Below I outline the steps to disable the key:
503 Service Unavailable Error After Switching Litespeed Rails Site From Production Mode To Staging Mode
Earlier I switched one of the Litespeed web server virtual hosts from production mode to staging mode and after gracefully restarting rails was receiving a 503 Service Unavailable error. Initially I thought that maybe Litespeed had to be restarted completely instead of just a graceful restart but that produced the same results. Below I describe the errors including errors in the Litespeed logs as well as how to resolve the issue which ended up being a silly mistake on my part.
I recently was installing Django for a test project and needed to upgrade Python on a CentOS server to 2.6. The current revisions available via yum on CentOS are 2.4. The yum package manager requires Python 2.4 still to function properly so upgrading Python to 2.6 manually will break the CentOS yum package manager. After a little bit of research I found a yum repository that would allow you to install Python version 2.6 in parallel to Python version 2.4. Below I explain how to install the new Python version, not break the yum package manager, and modify a Django project that references Python to use the 2.6 version instead of the 2.4 version.
A friend of mine was over tonight and we were troubleshooting a issue with SVN authentication via the Redmine project management software. Redmine is built with Ruby and on this server is running via Apache and Mongrel. I needed to set the project to run in development mode but wasn’t very familiar with the Mongrel setup. After some research I found it was easy to change the environment from production to development using the Mongrel Cluster .yml file for that project. When using Mongrel each site appears to get its own .yml file so you can modify whatever settings you want to on a per site basis. Below I describe what needs to be changed, default locations, and any other actions that need to be taken to restart the Ruby on Rails project in development mode.
