  • Digitize your movies

    Analog movies can be the easiest--or the hardest--medium to digitize, depending on the format you're working with. While older camcorder and video formats such as 8mm and Hi8 or VHS and Betamax tapes are easy to transfer, digitizing film can be difficult at best.

  • Digitize your music

    In my lifetime, music has been delivered on vinyl, cassettes, eight-track tapes, CDs, and audio DVDs. How do I listen to it now? Usually with a PC or a smartphone, and occasionally with an MP3 or other media player. I downloaded much of that music or ripped it from CDs, but the rest of it came from LPs and cassettes.

  • Digitize your documents

    The space required to store paper documents can be a problem. Digitizing your documents renders them exquisitely portable--you can store an entire library on your e-book reader with ease. And because paper documents can be turned into editable computer documents, they become searchable. Compare typing "Roosevelt" in a search field with spending all day scanning microfiche and old newspapers by eye to research the Square Deal or the New Deal. The digital document is a boon to researchers the world over.

  • Digitize your pictures

    Today the digital camera is ubiquitous, but photos used to be taken by momentarily exposing something called "film" to light. Yes, film--the ode to photo-sensitive chemical reactions that produced all of the pictures made before 1990 or so. Those images were, and quite of­­ten still are, transferred to photo paper and pasted into coffee table al­­bums. Sometimes they were processed into transparent 35mm slides and projected onto white screens for everyone's en­­joyment (or boredom, depending).

Looking back, I do not regret my decision to protect my tweets, and I'll tell you why.

  • Keeping track of your iPhone data usage

    When users had unlimited data there was no reason to be concerned with how or where that data was being consumed.

  • Prepare your PC for future data disasters

    Reformatting and restoring a PC is not fun--in the way spending 2 hours in the dentist's chair is not fun. You have to back up all your data (and pray that you haven't forgotten anything), reformat the hard drive, install Windows, track down missing drivers, find and reload all your software, restore your data, and pull out clumps of hair over the things you inevitably neglected to save. (Firefox plug-ins, anyone?)
