Upgrading to Mac OSX Lion

For the past month I've been waiting to sink my teeth into Lion (Mac OS X 10.7). Well i finally upgraded, I will say that this was the most difficult upgrade that i have ever experienced with apple. Well lets get to it Here are the following steps that i took in order to upgrade to lion from snow leopard: (Note these steps are not written in stone I'm sure there are better ways of upgrading to lion but these are just the steps that i took in order to make it work)


Step1: Make Sure Please make sure that you backup your system using time machine before you upgrade

Step2: Download Mac OS X Lion from the app store, (Note remember in order to upgrade to Lion you have to be running OS X 10.6.8 ) This update prepares you for your upgrade to Lion

Note: when running the install it will first install mac osx 10.7 and then reboot, and then will install any 3rd party drivers it needed and then reboot for a second time.

Step3: Now this is where i began having issues after running the installer my upgrade keep pausing at -42 minutes remaining, this was so crazy that i had the apple rep take a pic of my screen and send it into apple :) fun stuff, Here is how I over came that issue i had to reset my NVRAM and PRAM (Press and hold the Command-Option-P-R keys.) on my MACBOOK PRO which allowed me to do
a fresh install of Lion and the restored all my applications that i backed up using time machine.

Step4: Have fun and Enjoy Lion :)

Updating Python on RHEL

Good Morning its a wonderful Friday im so excited for no reason lol :) well anyways here is a quick tutorial on how to upgrade python without overwriting your existing version of python in RHEL(Red Hat Linux ) this method will also work on centos as well. So enough talking here are the steps that i took in order to get this to work.

Step 1 - > wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm


Step 2 -> rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm

Step 3 -> yum install python26

Step 4 -> rpm -qil python26 | grep /usr/bin

That's all so now when you want to use python 2.6 just point to the /usr/bin/python26 directory instead of the original /usr/bin/python. This is a safer method b/c python is so closely tied with yum that it can cause alot of issues :0. well enjoy your new version of python and happy scripting :)
