    Open to the World, Part 1

    ByRon Doyle

    If someone has access to your computer, there are many ugly things they can do.  There are the obvious, like letting someone get your tax returns, i.e., your social security number, watching what you are doing, checking out your checking account, and taking personal items off of your computer.  There are other villainous things someone…

    P@55w0rd Keepers

    ByRon Doyle

    I wrote a column last year about passwords.  Gee, don’t our digital worlds revolve around them?  If you work with computers on a regular basis you may have a million of them.  You may have them for logging onto your computer, websites, email, bank accounts, online stores, etc.  As I stated last year, “I do…

    Wireless or Wired for Your Home?

    ByRon Doyle

    You live in a home as we all do, whether an apartment, condo, townhouse, single-family, duplex, etcetera. You also use a computer in your home.  OK, I know that last one isn’t true for everyone but if you are reading this I will make that assumption.  You may be thinking about upgrading your internet connection;…

    Motorola Xoom – Tablet PC

    ByRon Doyle

    I have spent a couple of weeks testing out Motorola’s entrance into the Tablet PC market with the “Xoom”.  I have to say that I am impressed.  These are slick devices.  If you are looking into the tablets, this could well be the one to get. First of all it uses the Android (created by…

    File Encryption

    ByRon Doyle

    I have had many emails over time about security of thumb drives.  For instance, I sometimes think about what would happen if I accidentally left my thumb drive lying around somewhere. The finder could open my private files on that drive. That used to be a concern, but for many years I have been using…

    Kill Your Hard Drive

    ByRon Doyle

    So you have just gotten your brand new Windows computer and want to clean up your old one and give it away.  That is a nice thing to do for someone who may need a computer but isn’t able to afford a new one.  But you are concerned about your personal information on that old…

    Filename Color Enigma

    ByRon Doyle

    Several weeks ago I got an interesting email from Pat in Port Republic, about something I thought may affect many of my readers.  It also affects all Windows users at some time or another. Pat essentially said that, "…in an attempt to speed-up my computer I ran the Disk Cleanup and Disk Defragmenter programs."  So…

    Tech Bargain Finders

    ByRon Doyle

    I get quite a few emails about where the best places online to buy tech "stuff" are.  For instance, portable hard drives, thumb drives, and memory sticks seem to be some of the most popular right now.  I always suggest shopping in your local "brick and mortar" shops.  It really does help the local economy…

    Excel Formula Auditing, Part 2

    ByRon Doyle

    Last week we covered the first three items in Excel’s “Formula Auditing” tools: Tracing Precedents, Dependents, Remove Arrows and Show Formulas in Excel’s “Formula Auditing” tools. Today we will wrap up the last three features. I am sure you have never seen an “Error” popup box in Excel. That’s not true, unless you are an…

    Excel Formula Auditing

    ByRon Doyle

    At the end of last year I wrote a column with regard to Microsoft’s spreadsheet program Excel.  Due to the email response, (which to me at least was unexpected) it has now turned into three columns.  I guess there are more of you Excel users out there than I thought. I have continued to get…
