New barcodes can help you find your lost dog

This week my goal in writing this column is to give readers just a little background for the technology of the ever-more-ubiquitous “QR Codes” which are popping up everywhere. 

Computer world’s looming deadlines, relatively speaking

This week being the start of a new year is a good time to look at some upcoming events in the computer world.  For many technical support people this year is going to be, as was termed by the inimitable Yogi Berra, déjà vu all over again.

Dissecting Microsoft Windows XP ‘end-of-life’ policy

Last week all of Mexico celebrated dia de los muertos. This most colorful of holidays is a joyful time to celebrate the lives of those that have passed on and for most this is not a day to grieve but to give thanks. Perhaps this is as good a time as any for me to remind about one third of you personal computer users out there of a demise that will occur at your house next year.

Send uncrackable emails by using encryption keys

Recently in this column I mentioned the Electronic Frontier Organization and their web site found at prism-break.org where internet users concerned about their privacy may learn more about secure software and encryption.  I warned that there are no simple solutions, so if an easy answer is what you are looking for you may as well stop reading now.

Spell-checking feature can be a mixed blessing

In writing this column I am indebted to the members of my Editorial Review Board who volunteer their time to help make me look good by proofreading this column before it goes to press.  These people are friends who live outside of Mexico or people who have moved away but still want to continue reading this column.  My agreement with them is that they need to contribute by checking spelling, grammar and style.  In spite of everyone’s best effort, sometimes a mistake still manages to show up in print.

Internet gone down? Not an ISP problem? Fixes require rational steps, patience

Do something!  Do something!  Do something NOW!  That was the refrain Berta was hearing from the renters one weekend morning.  Berta is the employee in charge of a rental property and the best cook and housekeeper in San Miguel de Allende. Her technical expertise does not extend very far into network topology or internet troubleshooting though. Berta tries hard to please, sometimes too hard, so with the tenants vociferously wailing that they were being deprived of Facebook, she succumbed to the pressure of the moment.
