Cleaning Your Electronic Screens

Posted on May 19th, 2013

cleanscreenWhen cleaning computer, TV, cell phone or even camera screens, we have to make sure to take extra care in the type of products we use to bust the dust and gunk.

Most manufacturers warn against using products that contain any alcohol, ammonia, (ie. Windex/Glass Cleaners) or other strong solvents, and especially on LCD screens. To avoid mineral spots, I also recommend avoiding tap water.

I’ve been using Johnson’s Clean Screen for a few years now cleaning around a half dozen monitors and TV’s each week. The bottle is enough to last several years at least. The cloth is machine washable on the gentle cycle. The spray is a Reverse Osmosis (RO) solution water treatment technology that removes even the smallest molecules of mineral deposits, and impurities. It will remove fingerprints, make-up, dust, dirt, and oily residues from delicate surfaces and will not scratch, streak, damage or leave a residue. It comes with a lint free suede microfiber cloth that is ideal for applying the RO solution to any type of screen or glass surface, and is super absorbant and fast drying! To use you simply spray a few mists onto the enclosed cleaning cloth and wipe away.

Craigslist Scammers

Posted on November 21st, 2012

I’m starting a list of email addresses on Craigslist who have tried to scam me. I’ve had good luck in the past screening my replies from Craigslist by searching for the email address online and their name coming up on other people’s posts like this.

0-David-0 101.58486@germanynet.de
0-David-0 <ayanomatsumoto1@aol.com>
Sanchez BradfordSanchez@mail.com
Sanchez <urgentu1@aol.com>
– Seemed interested in some ‘table’ yet never would reply about which one. Sent a long sob story involving a money order and a sick daughter.

I’ll add more as I get them.

List only directories using ls and grep

Posted on October 22nd, 2012

Normally if you try to view directories in ls, ls will look inside that directory instead of the directory itself.  For example:

You want to find out about the directories in images but images has a ton of files in it.

Running this in the images directory will get you the directory information.
ls -l | grep "^d"

We are simply looking for the first character in our ls to be a ‘d’.  If so it marks a directory.
