How to recover lost product keys on Windows 7

Computer experts will tell you of the importance of performing regular backups to save your personal or work-related data in case of a system failure. Simple backup methods such as burning the data to a CD are perfect for archiving data that you put on your computer, but less effective when it comes to backing up installed programs. Installed programs usually require product keys to prevent software piracy or copying, and a misplaced or illegible key can lead to software becoming unusable to you in the event of a crash. Fortunately, NirSoft has a product that can retrieve the product … Read more

Google's smartypants math doodle

It's another confusing day on Google.com, with a foreign-looking (for most of us) equation greeting visitors to the search engine's front page. Wednesday's Google doodle is a tribute to mathematician Pierre de Fermat on his 410th birthday.

de Fermat spent most of his life working as a lawyer, but became the father of modern number theory in his spare time. Apparently the lack of e-mail, Facebook, and Twitter in 17th century France allowed the smartypantses of the era to be a lot more productive.

The equation in Google's doodle, x^n + y^n = z^n, … Read more

The 404 861: Where we're putting it all out there (podcast)

Have you ever received a phone call from a mystery number, but had no way to find out who was on the other side? A new online service called NumberGuru lets you perform a reverse number search to identify the source, and our friends from BeenVerified.com are in the studio to tell us all about it.

There are a few services like WhitePages that offer similar features, but NumberGuru is free and accessible from the Numberguru.com Web site, or with any one of its smartphone apps. Even better, the site lets you share comments on phone numbers to warn other users about spammers and telemarketers, and BeenVerified.com also offers background checks to dig up more details about the caller.

The 404 Digest for Episode 861

BeenVerified does background checks. Why bother to remember when you can just use Google? Great fear as PS1 discs begin to oxidize and degrade after 10 years.

Apple's Keynote, Pages, Numbers apps go universal

Apple this morning rolled out universal versions of all three of its iWork apps, bringing the suite to iPhone and iPod Touch devices.

Keynote, Pages, and Numbers (updated reviews), which have been on the App Store for the past year, were previously only available for iPad users. Today's updates shrink the same user interfaces down into pocket-size versions that let users create, save, open, and edit documents.

Along with going universal Apple has tweaked the user interface a bit to let users see thumbnail previews of documents to find them by sight.

The software suite originally made its debut on the Mac OS, beginning with Keynote, Apple's presentation software. Apple later added Pages then Numbers, rolling together all three applications into iWork. Apple now sells the individual applications through the Mac App Store, and in the iOS App Store, letting users get a single program without having to buy the others.

The apps continue to retail for $9.99 each, and this morning's update is free of charge to existing owners of the applications. The software is only available to users of Apple's more recent iOS products, including the iPhone 3GS and iPhone 4, third- and fourth-generation iPod Touch devices, and iPad and iPad 2. … Read more
