Obviously the actual value depends on your hardware and website. These settings are for 3g RAM server. Might tweak further with more statistics coming in.

Sometimes Magento refuse to install extension via Magento Connect. But you can always try to convert the extension to actual package and overwrite your existing installation. Of course, use with caution.

BTW so far I don’t like Magento.

First establish the tunnel:
ssh -D 8080 -fCqN user@server.com
Then Mac System Preferences > Network > Advanced > Proxies
Tick “SOCKS Proxy”: localhost:8080

Example:
### Select everything that has ID on the tag ###
$.extend($.expr[':'],
{
hasId: function(el)
{
return $(el).attr('id') !== undefined && $(el).attr('id') !== '';
}
}
$("#container :hasId");
### Select everything that's current in "view" ###
$.extend($.expr[':'],
{
inView: function(el)
{
var offset = $(el).offset();
return !(
(offset.top > $(window).height() + $(document).scrollTop()) ||
(offset.top + $(el).height() < $(document).scrollTop()) ||
(offset.left > $(window).width() + $(document).scrollLeft()) ||
(offset.left + $(el).width() < $(document).scrollLeft())

A list of things you can do to improve your (ubuntu) server security.
Install mod_evasive and mod_security
apt-get install libapache2-mod-evasive libapache-mod-security mv /etc/modsecurity/modsecurity.conf-recommended /etc/modsecurity/modsecurity.conf
Tweak php.ini (/etc/php5/apache2/php.ini)
# append those to disable_functions # system,show_source,symlink,exec,dl,shell_exec,passthru,phpinfo,escapeshellarg,escapeshellcmd allow_url_fopen = Off open_basedir = /home/www-data/
Install curl so you can still grab remote files after fopen turned off
apt-get install curl php5-curl
Install fail2ban
apt-get install fail2ban
Let unattended upgrades
apt-get install unattended-upgrades dpkg-reconfigure unattended-upgrades
First install homebrew if you haven’t already:
https://github.com/mxcl/homebrew/wiki/installation
Now install postgresql via homebrew
brew update && brew upgrade brew install postgresql
Wait for everything to finish.
Create postgreSQL database:
initdb /usr/local/var/postgres
Fix conflict from Mac’s own postgreSQL:
source: http://nextmarvel.net/blog/2011/09/brew-install-postgresql-on-os-x-lion/
BREW_POSTGRES_DIR=`brew info postgres | awk '{print $1"/bin"}' | grep "/postgresql/"`
LION_POSTGRES_DIR=`which postgres | xargs dirname`
LION_PSQL_DIR=`which psql | xargs dirname`
sudo mkdir -p $LION_POSTGRES_DIR/archive
sudo mkdir -p $LION_PSQL_DIR/archive
for i in `ls $BREW_POSTGRES_DIR`
do
if [ -f $LION_POSTGRES_DIR/$i ]
then
sudo mv $LION_POSTGRES_DIR/$i $LION_POSTGRES_DIR/archive/$i
sudo ln -s $BREW_POSTGRES_DIR/$i $LION_POSTGRES_DIR/$i
fi
if [ -f $LION_PSQL_DIR/$i ]
then
sudo mv $LION_PSQL_DIR/$i $LION_PSQL_DIR/archive/$i
sudo ln -s $BREW_POSTGRES_DIR/$i $LION_PSQL_DIR/$i
fi
done
Also, make sure /usr/local/bin comes first in your /etc/paths. Run “brew doctor” to check if there is any path issue.
You need to fix those issues before install bundled stuff such as rails pg gem (if not, use “gem uninstall pg && gem install pg” to reinstall pg gem).
Start service:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
To stop service:
pg_ctl -D /usr/local/var/postgres stop -s -m fast
To make postgreSQL auto start:
mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/postgresql/9.1.3/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
To remove this auto start:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
To upgrade from old version of this auto start (first remove auto start see previous section):
cp /usr/local/Cellar/postgresql/NEW.VERSION.ID/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
To Install adminpack (so pgAdmin stop complaining):
psql -d postgres CREATE EXTENSION adminpack;
Also, download pgAdmin:
