Secure HTTP (SSL/TLS) has become a must if you are planning to setup a website which includes user authentication (ie. login box) or sensitive data. HTTPS prevents the sensitive data from being transfered across the network in clear text where it is susceptible to being sniffed or altered. Here is the tutorial on how to setup a secure HTTP on Apache web server in Ubuntu 10.04 (Lucid Lynx).
What do you need?
Step 1: Create a self-signed certificate
You need to create a self-signed certificate with openssl. To do that you will need to generate the server key.
openssl genrsa -des3 -out server-sec.key 4096
…and certificate signing request (CSR)
openssl req -new -key server-sec.key -out server.csr
After that, generate the server certificate by signing it with the server key.
openssl x509 -req -days 365 -in server.csr -signkey server-sec.key -out server.crt
Keep the server-sec.key in a secure location, with read/write permission assigned only to root. Then generate a password-less copy of the key for Apache use.

Sometimes you might have no choice except to open Microsoft Office 2007 (*.docx) files that you’ve just received in your email. The problem is, you do not have any other application that support Office 2007 format.
Here’s an easy way to (kinda) solve that problem, you can convert Microsoft Office 2007 files online, using Google Docs.
The steps are easy, you need to login into your Google Docs account, then upload the Office 2007 files. After that, you can choose the “Download file as” option to convert the file to your favorite document format (typically OpenDocument or older *.doc Microsoft Office word document).
Bear in mind that the conversion is not 100% perfect and there will be parts of document that won’t look exactly as the original ones.
Here’s an easy way to block annoying advertisement and malware sites using ‘/etc/hosts’ file.
First edit the /etc/hosts files using your favorite text editor :
sudo gedit /etc/hosts
Then, paste the list of ads/malware servers in the ‘hosts’ file. You can get the list from http://someonewhocares.org/hosts/ or by searching through Google.
Close the file, and Save. The change will take effect immediately after that. One of the side-effect from this modfication is that your web surfing experience would be significantly faster because your browser does not have to wait for the annoying advertisement to load.
