Most people are familiar with firmware on a very basic level given that they are often prompted to download firmware updates on computing devices such as smartphones, laptops, printers and routers. Yet many are oblivious to the potential security risks that firmware can bring. To address this, Google's malware scanning service VirusTotal can now help users identify harmful firmware.

Keeping your router secure is a fairly basic bit of networking sense, but it doesn’t help if the firmware updates on your router apparently don't fix the very bugs they're meant to squash.

Windows/Mac/Linux: Open-source MP3 firmware Rockbox has released its first major update in three years, adding support and stability for more MP3 players and playback of more file types. Rockbox has long been the best tool to breath new life into an aging MP3 player, from first through 5.5 generation iPods to iRiver, Sandisk, and Archos players (see all the supported players here). Rockbox features include Last.fm support, album art, games, video playback, and tons more. Better yet, the new release comes with a streamlined installation tool called RockboxUtility that works on Windows, Mac, and Linux and makes installation simple. With the latest release, Rockbox easily earns its spot as one of the 20 best iPod utilities. If you're a Rockbox user, share your favourite features in the comments. Rockbox

If you're using a consumer grade point-and-shoot Canon digital camera, you've got hardware in hand that can support advanced features way beyond what shipped in the box. With the help of a free, open source project called CHDK, you can get features like RAW shooting mode, live RGB histograms, motion-detection, time-lapse, and even games on your existing camera. Let's transform your point-and-shoot into a super camera just by adding a little special sauce to its firmware.

You might think your consumer-model Canon digital camera can't pull off the kind of fancy shots and tricks that make you stop and look on Flickr—until you unlock your camera's potential with the Canon Hacker's Development Kit. The completely reversible firmware upgrade, available for models running the DIGIC II or DIGIC III platforms, speeds up fast shutter modes (from 1/1,600th of a second to 1/60,000th!), allows for time-lapse photography and other scripted shots, unlimited interval shooting, better HDR pics, and much, much more. Wired's How-To Wiki has a handy guide and introduction to the CHDK, available at the link below. I lack a Canon to try out the CHDK, so let your fellow readers know what you think if you've taken this step already. Supercharge Your Camera with Open-Source CHDK Firmware

Steve Jobs' Macworld keynote was today, and among a bevy of new hardware announcements, Apple has pushed out two very significant updates for iPhone and iPod touch users. Apple has added multi-recipient SMS (iPhone-only), faux-GPS on Google Maps using cell tower triangulation, Web Clips (i.e., bookmarks of web sites on your home screen), and home screen icon customisation via drag and drop. iPod touch users can now get the Mail, Maps, Stocks, Notes, and Weather apps that came standard on the iPhone for a $24.99 upgrade (these features will come standard in new iPod touches).
