Non-linear video editing tools are great, but they're not always the best tool for the job. This is where a powerful tool like ffmpeg becomes useful. This tutorial by Elliot Isaacson covers the basics of transcoding video, as well as more advanced tricks like creating animations, screen captures, and slow motion effects.

There's nuttin like a Cool Project to give you some relief from the summer heat, so get out your parka cuz we got a bunch of em. First up is the BUG, not a bug, The BUG. It's got a GPS, camera and more, in a hand-sized package that's user programmable. The BUG does everything. It's both a floor wax and a dessert topping. Get one now. Need a software version of a Swiss Army knife? Take a look at Billix, and don't leave home without it. Then, chew on this one, an X server on a Gumstix device driving an E-Ink display. Need more storage? How about 16 Terabytes? Can do.
And, of course, we have the usual cast of characters: Marcel, Reuven, Dave, Kyle, Doc, plus the new kid on the block Shawn Powers. But it doesn't stop there: build a MythTV box on a budget, build your own GIS system, set up the tools to monitor your enterprise and more. Finally, remember The War of the Worlds? Now you can play too.

Overall, good info

I found the article to be quite helpful overall. I was initially confused about setting up my system to play MIDI files. It would have been more clear if the author would have emphasized that not all sound cards have a wavetable they can use for playing MIDI. I spent several hours chasing my tail and on Google trying to play a MIDI file on my T23 laptop and an Intel 800 series chipset with AC97 sound. I slowly came to the slow realization that Timidity++ is the only hope on it.
Meanwhile, I found the brief note of his SB Live! card helpful by at least giving me a lead. I have an SB PCI-512 card that also uses the emu10k1 driver and digging out the original CD revealed a file named 8MBGMSFX.SF2 on it. A bit of Googling revealed that this was the needed file and indeed, playing MIDI files now works.
I realize some of these low-level details aren't necessarily a function of ALSA, but since much of the article was devoted to MIDI and sequencing, I think they should have been developed a bit more. For all of their popularity, modern soundboards are largely a mystery for most of us.
Once we can listen to streaming audio or a CD, most of us consider the audio to be installed. My thanks to Mr. Phillips for an interesting article with many new ideas to explore.
