Enable Xdebug in MAMP

Uncomment the zend_extension line and modify the /Applications/MAMP/bin/php/php5.x/conf/php.ini file to look like this:-

[xdebug]
zend_extension="/Applications/MAMP/bin/php/php5.4.10/lib/php/extensions/no-debug-non-zts-20100525/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host=localhost 

; On my machine, the default port 9000 has already been taken by something else.
xdebug.remote_port=9099 

; Recommended when using Symfony
xdebug.max_nesting_level=250

Then restart the servers in MAMP.

Show print history on Mac

When I opened the web based CUPS admin interface to show print history:-

http://localhost:631/jobs?which_jobs=completed

I got the "Internal Server Error" message.

To fix it, I used the following commands

sudo cupsctl --debug-logging
sudo cupsctl --no-debug-logging

Custom php.ini on shared hosting

• Find the default php.ini path. Mine is /usr/local/lib/php.ini

<?php phpinfo() ?>

• Copy the default php.ini to the user's home folder and customise it.

<?php copy("/usr/local/lib/php.ini", "/home/username/php.ini") ?>

• Create a .htaccess file in the user's home folder with the following content.

SetEnv PHPRC /home/username/php.ini
# The following lines are important if the php.ini file is put in the document root.
<Files php.ini>
order allow,deny
deny from all
</Files>

The system is running in low-graphics mode after upgrading the VirtualBox Guest additions to 4.2.12

I tried switching to use gdm instead of lightdm to see whether it could help but it didn't so I rolled back to v4.2.10 while waiting for v4.2.13 which was reported that this problem has been fixed.

• Rebooted the machine in recovery mode in the Grub menu by, while booting:- 
• Pressing ESC, or
• Holding down the Shift key (this works better for me).
• Uninstalled the VirtualBox Guest additions

cd /opt/VBoxGuestAdditions-4.2.12
./uninstall.sh
reboot 

• After reboot, the screen was black. Here is what I did to fix this,
• Pressed Cmd + F1 (or Alt + F1, don't know why Ctrl isn't needed on my machine) to switch to tty1.
• Made LigthDM the default display manager

sudo dpkg-reconfigure lightdm
sudo reboot  

        But it didn't work. It turned out that I also had to modify /etc/X11/default-display-manager to have the full path to lightdm like this.

/usr/sbin/lightdm

Then rebooted,

sudo reboot

After that, I could continue installing the VirtualBox Guest additions v4.2.10 and now everything is back to normal.

Install httrack using brew on Mac

Typed

brew install httrack

Then I got:-

==> Downloading http://download.httrack.com/httrack-3.46.1.tar.gzAlready downloaded: /Library/Caches/Homebrew/httrack-3.46.1.tar.gz
Error: SHA1 mismatch

Archive: /Library/Caches/Homebrew/httrack-3.46.1.tar.gz
(To retry an incomplete download, remove the file above.)

So I did:-

brew update

Then I got:-

error: The following untracked working tree files would be overwritten by merge:     Library/Formula/libmusicbrainz.rbPlease move or remove them before you can merge.AbortingError: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

To fix it, I did:-

cd /usr/local
git fetch origin
git reset --hard origin/master

After that, I could run "brew update" and "brew install httrack" again with no problem.
