takizo, not takezo

Locking your screen is critical when you are using your laptop in public or in the office, if you don’t lock your screen, within a second the data in your laptop might be owned by somebody who walk pass by your desk.

Does Apple Mac OSX support screen lock by keyboard shortcut key? I would say no, but you can do it with simple hacks.

first :

cd /destination/directory

second :

split /source/directory/big-huge-file prefix-to-apply-onto-splited-files

Voila !!!

(use the parameter -b to specify the size of splited files in BYTES, NOT kb, mb or gb)

date -d ‘<Unix epoch> <epoch date> sec’

e.g. date -d ‘1970-01-01 988822888 sec’ would dated “Wed May 2 17:31:28 MYT 2001″

20080430 :

get a particular date in epoch, e.g. date -d ‘Apr 30 2008 00:00:00′ ‘+%s’

dig <record type> <host.name>

e.g dig SRV _someservice._port.hostname.domainame.com.my OR dig SRV _https._ICMP.host.takizo.com

e.g. rm -rf backup-20070[8-9]-*

would delete :

• backup-200708-morning
• backup-200708-evening
• backup-200709-night
• backup-200709-latenight

but not :

• backup-200706-morning
• backup-200707-afternoon
• backup-200711-midnight

e.g. ls backup-20070[1-9] would list all backup starting from January to September but leave October, November & December out, of year 2007.
