The COWON iAudio 7
I was on the prowl for a new portable media player. I wasn't happy with just a music player though. I wanted something that would play videos, FM radio, show pictures, display text, record my voice, record old LPs via a line-in jack, record FM radio and play music—not just MP3s, but Ogg, FLAC and (yuck) my few WMAs. Finally, it would be great if it sounded better than, and had double the battery life per charge of, an iPod Nano. And, I found it, the COWON iAudio 7. This Swiss-Army knife of multimedia players comes in 4GB, 8GB and 16GB varieties of Flash drives that cost $150, $200 and $300 retail, respectively, but you easily can find one for less at most on-line retailers that sell this player. Best of all, this player is very Linux-friendly.
Its default setting is for use as a UMS device out of the box. That means you can move your media in and out of this player easily by dragging and dropping to and (unlike many other players) from this device. You don't need to install any software to do this, just turn it on, plug it in to any of your computer's USB ports, and within seconds, it mounts as an external drive. You will see an icon pop up on your desktop when it mounts. Open it, and navigate to whatever folder you wish to move files to and from, and when you're done, simply right-click and unmount it.
Videos do require re-encoding prior to loading them for playback on the iAudio 7, and there is an open-source Linux solution for this purpose. This is necessary, due to the small size of the iAudio 7. Smaller than a credit card, it's about the same size as a large pack of gum. The screen measures 1.3", 160 x 128 dot and is a 260,000 color TFT LCD. Small as this screen is, it has good detail and color saturation. This makes it relatively enjoyable to view a TV show or even a movie. An hour of video after re-encoding is about 178MB, so it's possible to carry quite a few TV shows or movies in this player and still have room for your music library too. If you think you'll be carrying a lot of videos, you might want to opt for the 16GB version. Videos need to be encoded in xvid-.avi at 256–384kbps, at no more than 15fps. I provide a step-by-step rundown on how to re-encode later in this article.
The iAudio 7's best feature is its sound quality. It puts most other players to shame. The earbuds COWON packs with this player are of average quality. To really appreciate the sound quality this player puts out, you need to buy better earphones, like the Shure e2cs I own or any other $100+ brand of your choice. Another way to hear this player's outstanding audio quality is to plug it in to your car's radio, if it's equipped with an MP3 player (line-in) jack, like many newer models now have.
Its equalizer is called Jet Audio, which is a software branch of COWON. This little player has the most elaborate choices for equalization I ever have seen on any player. If you can't find a setting you like listening to, you might want to consider buying a hearing aid instead—it's that good.
Controlling the iAudio 7 is done with a touch interface to the right of the screen. It's called a swing-bar, and it's fairly easy to learn how to use, but it can be a bit difficult getting used to the touch sensitivity. You can make it better by going to Settings→General and changing the touch sensitivity to low. Fortunately, it does have a lock switch, so when it's locked, you can run it in your pocket without fearing it will switch to something you don't want to hear. To use the swing-bar, simply stroke the bar up or down, or hold your finger down at one end or the other to scroll through the menu. Tapping either end of the bar tells it to skip to the next file. The play arrow opens any file or function, whether it's music, video, radio station and so on. You can shuttle forward or reverse with videos or music, using the swing bar. This is useful if you recorded a TV show off-air with commercials or if you just want to shuttle over a segment of video. If the shuttle speed is too slow for your liking, you can make it faster by going to Settings→General and increasing the scan speed.
There also are three control buttons on the top of the player. The left button is power on/off/hold. The center button is the master menu control, which switches between all folders and playlists. The right buttons are for volume up and down. On the left side are the earphone and line-in jacks, and on the right side is the USB port, with a sturdy rubber flap covering it.
Speaking of playlists, you may be thinking that because you would be using it in UMS mode, you wouldn't be able to save custom mixes of your favorite songs. You would be wrong. The iAudio 7 has a feature called DPL, for Dynamic Playlist. To use this feature, simply hold the play button while playing a song until you see a small box that has a choice of DPL, Bookmark or Lyrics. Choose DPL, and it saves that song to the DPL folder. You can arrange the songs in that folder in any order you like, up to 200 songs. Just remember, the last song added always ends up at the bottom of the list.
You also can create subfolders on your computer for DPL, if you want to have special mixes of songs. Simply load the mix folder to the Music folder on the player. Then, on the player's main menu, click on Music, navigate to that folder, hold down the play button, and choose DPL on the drop-down menu. To get to the DPL folder, simply navigate to the Music folder on the main menu (using the top-center button), scroll down and click on Dynamic Playlist.
I'm sure you're curious about those other choices that appear in the menu box. Bookmark simply bookmarks your song or video where you paused it, if you want to navigate away to another song or folder. Lyrics displays the lyrics to the song you are playing. (This works only for songs that have this feature.)
The line-in, voice and FM recording features also are a nice touch, and they do make quality recordings. I did find it odd that with the support for Ogg, FLAC and Xvid open-source files for playback on this player, it records only line-in, voice and FM radio in unprotected WMA with a limit of 128kbps. In spite of this, the recordings sound surprisingly good, thanks to the Jet Audio equalizer. Voice recordings are done through a built-in mic, which sounds fine on the higher bit-rate settings. Line-in recording is one of those functions I feel all media players should offer. Maybe it's because it appeals to those like myself, who are old enough to have a large collection of music on vinyl LPs. In any case, you can digitize all your old vinyl records by recording directly into the iAudio 7 from your analog stereo amp. Simply connect your amp using standard RCA A/V plugs connected to an RCA-to-mini-plug conversion jack, and connect the mini-plug end to the line-in jack on the iAudio 7. If you want to burn a CD of the music you digitized, simply drag the songs out of the player and on to your computer for burning.
The FM radio has good signal pick up and can be used in several ways. You can scan for stations manually if you want, but it's easier to auto-scan all the stations it can pick up in your area and then assign presets for the stations you like. As for recording FM radio, you can do it on the fly, or you can use the timer settings in the Settings menu and preset a time to record a station—like a TiVo for radio. This same timer also can be used to lull you to sleep with your stored music or to wake you up with the FM radio—like a clock radio.
The picture and text display functions are pretty straightforward. Both can be displayed separately as your music plays. To load text or pictures, simply drag and drop into the appropriate folder, just like all other content stored on the player. Pictures are resized automatically as they load. They also can be used as wallpaper for your screen, or you can hold down the play button while the picture is displayed to add it to a slideshow of your own creation.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
