  • Open source FreeOTFE encrypts disks handily

    FreeOTFE may sound like a political bumper sticker, but it stands for "Free On The Fly Encryption." The "Free" part is self-explanatory; "On The Fly Encryption" refers to the encrypting/decrypting of data as it is written to or read from your hard disk.

  • Enable iTunes Home Sharing in iOS 4.3

    The next major iOS update is slated to be released this Friday, March 11, alongside the ultra-hyped iPad 2. One of the key features is a little something called iTunes Home Sharing, which allows users to stream music, podcasts, movies and more from PC to iOS device.

  • 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).

  • Should I protect my tweets?

    When I signed up for a Twitter account in the summer of 2009 I spent some time thinking about whether or not I should protect my tweets. As a novice Twitter user, I had to decide whether the benefits of protecting my tweets outweighed the drawbacks. 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. Since AT&T dropped unlimited data in favor of tiered data caps, though, users have struggled to understand data usage, and now AT&T is faced with a law suit accusing it of systematically overcharging customers.

  • 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?)

  • Stop Facebook from cluttering your inbox

    There's a fine line between awesome and annoying. Take Facebook: Most of the time, it's great, but a few things about the service drive me crazy.

  • How Quora could help your business

    Question-and-answer sites like Yahoo Answers may offer a quick way to ask questions and get answers, but they tend to be plagued by wisecracks, poor spelling, and generally low quality. On the other hand, a new site targeting this niche, Quora, is going to great lengths to keep quality high.

  • There's never been a better time to upgrade RAM

    In case you haven't noticed, memory prices have dropped through the floor. As such, I've been busily upgrading every computer I can get my hands on. For example, my 2009 MacBook Pro has been maxed-out to 8GB, which involved buying two 4GB SODIMM modules. The cost? Just US$97. I dare say I could have got them even cheaper if I'd shopped around.
