If you want to put custom entries in your computer’s DNS (for running addresses for a local server for example) you need to edit your system’s hosts file. On Unix systems this can be found at:
/etc/hosts
On Windows systems, you need to go to:
C:\Windows\system32\drivers\etc\hosts
To add a custom entry, first enter the IP address (if you’re running a local server you’ll want to set this as 127.0.0.1), then put a tab and then the host name.
One utility Mac OS X seems to be lacking is a simple text editor such as Notepad for Windows. It comes with TextEdit but the problem is that this uses rich text format (RTF) which is very annoying when editing system files or code.
Thankfully, you can reconfigure it to use plain text.
Simply go to TextEdit on the menu bar and hit Preferences. The top option should allow you to toggle between Plain Text and Rich Text.
Snapz really annoys me because I paid money for what is supposed to be the best product out there, but it’s actually incredibly hard to use because every time I want to take a screen shot I have to google for the shortcut key. By default, it’s this.
