Better battery life Macbook Pro with gfxCardStatus Update: Just installed Mac OS X 10.8.4 and now it works much better. Fantastical, Growler, Hardware Grower, Scrivener and Tweetbot now works without switching cards. Later models of Macbook Pro computers comes with dual graphics card. This makes it possible to use a low performance card when not using graphics intense applications, and automatically switch to the faster, but less energy efficient card if needed. But how do you know which card is currently active? There is a great application available called gfxCardStatus that shows you when the computer switches, and even uses notifications. If your on the move and on battery power, you can force the computer to use the Integrated less power draining graphics card. If you need full speed, just select the Discrete card. The third alternative is to have it in the normal Dynamic Switching Mode. But there’s a snag when using Switching Mode.

When setting up my new web server I had a problem when installing vsftpd on Ubuntu Server 12.04 LTS. After doing the sudo apt-get install vsftpd and enabling login for local users, I got a “Server 530 login incorrect error” when trying to connect with a local user.

[cc lang=“bash”]anonymous_enable=NO local_enable=YES write_enable=YES[/cc] But the ftp server still refused to let me login with any of the users on the system. I tried remove and reinstall, but the problem persisted. Finally I found a thread where others had the same problem. And here’s how to fix the problem. [cc lang=“bash”] sudo apt-get remove vsftpd sudo rm /etc/pam.d/vsftpd sudo apt-get install vsftpd [/cc] ...

[caption id="" align=“alignright” width=“448”] Image by DigaoSPBR[/caption] My internal hard disk would continuously spin on my MacBook Pro and never goes to sleep. I replaced my internal drive on my MacBook Pro with an SSD disk, which made a massive difference in speed. At the same time, I removed the DVD unit and installed a new 500gb drive instead. The extra disk went to sleep when not in use, but then started within a couple of minutes or less. Here’s what I did to fix that problem. ...

I have had this annoying problem with my Macbook Pro.
