    I was recently playing around with a Foscam FI9821W V2 webcam, and found its interface quite lacking in features.
For example, it has no option of syncing alarm videos to any remote server. So it would just record until your SD
card fills up at which point you would have to manually free up space.
Luckily, it also runs an (undocumented) FTP server on port 50021 where you can access and manage all of SD card 
contents. So, you can just run the following command as often as you like to move all new videos to your NAS.

    Here's how to install munin-node and start monitoring a MongoDB server on a fresh Ubuntu box
sudo apt-get install git munin-node
git clone git://github.com/erh/mongo-munin.git /home/ubuntu/mongo-munin
sudo ln -sf /home/ubuntu/mongo-munin/mongo_btree /etc/munin/plugins/mongo_btree
sudo ln -sf /home/ubuntu/mongo-munin/mongo_conn /etc/munin/plugins/mongo_conn
sudo ln -sf /home/ubuntu/mongo-munin/mongo_lock /etc/munin/plugins/mongo_lock
sudo ln -sf /home/ubuntu/mongo-munin/mongo_mem /etc/munin/plugins/mongo_mem
sudo ln -sf /home/ubuntu/mongo-munin/mongo_ops /etc/munin/plugins/mongo_ops
sudo service munin-node restart
 
You can then test it by running:
sudo munin-run mongo_conn

    Here's the easiest way to install Sun (Oracle) Java JRE on newer
versions of Ubuntu (tested on 11.04) without resorting to third party
PPAs.
sudo apt-add-repository "deb http://archive.canonical.com/ natty partner"
sudo apt-get update
sudo apt-get install sun-java6-jre

    There's lots of information online on how to move MySQL data and logs to
a new location but I had to use a combination of several guides in order
to get it fully working. This is a reference for me if I ever need to do
it again or for anyone else that may find it useful.

    I recently had to sign a Mozilla Firefox extension using a VeriSign Code
Signing certificate. The process to receive the cert is pretty
straightforward - you apply for the certificate on VeriSign's page
where you input your company details and payment information. By the
way, you can use "THEDEAL99" promo code to get $400 off $499 for a
Microsoft© Authenticode© certificate to make the price somewhat
reasonable. After your application is submitted they verify the validity
of your company and the information you put in and issue you the
certificate that you can use for code signing.
