MAMP doesn't come with XHProf support by default and sometimes we need more than just a simple debug tool with Xdebug.

Just for the record, I'm posting this in the current version of MAMP, that is 2.1.1 and in the Mountain Lion OSX 10.8.1 version. I'm not sure if it works the same way on other versions, but you can leave a comment about it :)

So, how can we enable it and make it work?

Requirements
First of all you'll need Xcode and Command Line Tools. Download and install them.

AWS Certification notes

Those are my personal notes on AWS Solution Architect certification preparation. Hope you find them usefull.

To pass AWS certification, you should have:

• Sound knowledge about most of the AWS services ( EC2, VPC, RDS, Cloudfront, S3, Route53 etc,)
• Hands on experience with AWS services.
• Good knowledge of disaster recovery, security and High availability architectures.

If you do not have prior hands-on experience and knowledge or you have little knowledge about AWS services, it is better to take an online course. If you already have experience in architecting solutions on AWS it is not necessary to take an online course.

grep -rnw '/path/to/somewhere/' -e "pattern"
-r or -R is recursive,
-n is line number, and
-w stands match the whole word.
-l (lower-case L) can be added to just give the file name of matching files.
Along with these, --exclude or --include parameter could be used for efficient searching. Something like below:
grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"
This will only search through the files which have .c or .h extensions. Similarly a sample use of --exclude:

grep --exclude=*.o -rnw '/path/to/somewhere/' -e "pattern"

# enable site
sudo a2ensite
 
# disable site
sudo a2dissite
 
# enable an apache2 module
sudo a2enmod
 
# e.g. a2enmod php4 will create the correct symlinks in mods-enabled to allow the module to be used. In this example it will link both php4.conf and php4.load for the user
