CentOS/Redhat/Fedora display BIOS information

The dmidecode utility will display the SMBIOS (System Management BIOS) or the DMI (Desktop Management Interface) table. It can be very useful to determine your current hardware and other good information.

To display type options:

# dmidecode -t
Type number or keyword expected
Valid type keywords are:
bios
system
baseboard
chassis
processor
memory
cache
connector
slot

Here is an example:
# dmidecode -t processor
# dmidecode 2.9
SMBIOS 2.3 present.

MacBook Pro page down through messages in Mail

To page up or down through the list of messages in Mail on a MacBook Pro, hold down the fn and control keys and hit the up or down arrow depending which way you want to go in the list. Note: this does not select them, but at least allows you to scroll through them quickly.

This has been one of the most frustrating problems I have had using the MacBook Pro. I get a lot of mail that just need to scan and delete. It would be nice if I knew how to select them too. In thunderbird, you just use the fn key and the arrows to page down/up. If you use fn and shift, this will also select them. I guess I will have to use thunderbird, if I cannot find a solution.

I have many mail accounts, and I like the way Mail put the Inbox for all of them up top. It makes it easy to get to the unread messages. I would like to try to use Mail, but I need to be able to select too.

Return top
