F-Spot 45
If you need to manage a photo collection under Linux, F-Spot is the tool to use. After importing your photos (from a camera, a flash card, or from the filesystem), you can edit, tag, and sort them, and finally upload them to a huge range of sites, including Flickr, Facebook, Picasa, or to your own website. It supports every photo format you could imagine, and while it can't edit RAW files directly, it can convert them to JPEG automatically for you.
MythTV 42
MythTV is one of Linux's real killer apps - a digital video recorder and TV-friendly media playback interface to rival Windows Media Center. It has full digital TV support, letting you pause and rewind live TV and schedule recordings based on downloadable program guides. With multiple tuner cards, you can record multiple programs at once, and with its networked design, you can put your tuners in a backend system and stream live and recorded TV to multiple frontend systems.
CheckGmail 52
As the name suggests, CheckGmail checks your Gmail account periodically, so you don't have to. It drops an icon into the notification tray and polls your Gmail account to check for new mail. If anything arrives, it pops up a notice and lets you preview the mail's contents, with links to open the complete mail inside Gmail in a new browser window. By default, it just checks your inbox, but you can configure it to check specific labels as well.
Transmission 44
BitTorrent is the ideal way to download your favourite Linux distribution's latest release, and the ideal all-round client is Transmission. It's very lightweight, especially compared to Java-based clients like Vuze, and it's also easy to set up and use, with network auto-configuration, but it still has a wealth of features. Along with the traditional GUI interface it has command-line and web interfaces, and a daemon option, which is very useful on remote servers. Also available for Mac OS X.
Aqualung 48
Linux has no shortage of music players, but Aqualung's dedication to high audio quality sets it apart. It lets you rip your CDs in perfect FLAC format or in high-quality MP3 or Ogg Vorbis formats, and then play them back without gaps, so you'll never hear glitches between tracks again. Aqualung also supports high-quality resampling for those soundcards that require it, and Linux-standard effect plugins, including equalisers, amp simulations, and spatial stereo processing effects.
