Speed up Firefox and Conserve Memory

No Comments »

 

As we all know that the Firefox browser takes a lot of our computer memory, this is of course made a slow computer performance and also affect our activity on the internet.

Why does this happen? One main cause is because Firefox itself. Although popular, it seems that Firefox is not a lightweight browser. This browser is quite fat and wasteful, because it spent a fairly high computer resource. For the first time you run it this browser (version 2) spends at least 10 mega memory in Linux, and 20 mega in Windows. The more you open tabs / web then spent the greater memory and the CPU busies all you work. Read the rest of this entry

Copy and Paste is not working on my Remote Desktop Connection

No Comments »

 

A very annoying occurrence that I sometimes suffer is when all of a sudden the copy and paste function stops working when I am connected to a remote machine. Turns out the problem is coming from a little process called rdpclip. Rdpclip (remote desktop clipboard) is responsible for managing a shared clipboard between your local host and the remote desktop (the process runs on the remote machine not your local host).
So what do I do when clipboard stops working? Read the rest of this entry


How to limit the number of recipients in Postfix

No Comments »

 

1) If you wish to limit the total number of recipients in an email, you can do that using the variable:

smtpd_recipient_limit=10
# postconf -e 'smtpd_recipient_limit=10'
# /etc/init.d/postfix restart

2) If you wish to specifically limit the number if recipients in TO and CC. You can do that with the option in main.cf:

header_checks = regexp:/etc/postfix/header_checks

contents of /etc/postfix/header_checks

/^To:([^@]*@){50,}/ REJECT Sorry, your message has too many recepients.
/^Cc:([^@]*@){50,}/ REJECT Sorry, your message has too many recepients.

This will not work for BCC. By the time the message gets to header_checks, the BCC header will be already removed.


Protect Your Facebook Account With Login Approvals

What is Facebook’s Two-Factor Authentication?

Facebook’s two-factor authentication (a.k.a Login Approvals) is an added security feature used to help prevent hackers from logging into your account with a stolen password. It helps you prove to Facebook that you are who you say you are. This is done by Facebook determining that you are connecting from a previously unknown device or browser and issuing you an authentication challenge, requiring you to enter a numeric code that generated by using the Code Generator tool from within your smartphone’s Facebook app.

Once you have entered the code you received on your phone, Facebook will allow the login to take place. Hackers (whom hopefully don’t have your smartphone) will not be able to authenticate since they won’t have access to the code (unless they have your phone)
