Improve Apple Services with AirPort Base Stations

You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.

Two quick bits for you to ponder this week: scientists encoding data in DNA (but it’s not cheap!) and an independent designer’s mockup of what a future Mac Pro could (but probably won’t) look like.

Unthrifty Loveliness: Shakespeare Sonnets Encoded in DNA at $12,400 per Megabyte -- Ewan Birney and Nick Goldman, two scientists from the European Bioinformatics Institute, have worked out a system to encode text, audio, and other data in DNA. Teaming up with Aligent Technologies, the two encoded all of Shakespeare’s sonnets, an audio clip of Martin Luther King Jr. speaking, and a photograph into a synthesized DNA sample. Though Aligent did the DNA synthesizing work for free, the cost of the DNA synthesis is estimated to have been roughly $12,400 per megabyte. Luckily, prices for DNA synthesis are dropping, and it is estimated that 50 billion megabytes of text, roughly equivalent to everything ever written by humans, could be encoded into a sample that would weigh less than “a granola bar.” This takes the idea of cloning your data to an entirely new level.

Independent Designer Imagines a Future Mac Pro -- 3D designer and illustrator Peter Zigich has posted a number of beautifully rendered mockups of what a future Mac Pro could look like, were it to use significantly more efficient CPUs. It is, of course, highly likely that Peter’s designs will bear no resemblance to what Apple is reportedly planning for this year’s Mac Pro refresh, but it’s still fun to ponder whether or not his designs could work.
