+ - Google is closing Google Code->

Kohenkatz writes: Citing increasing spam and abuse, as well as the rise of Github and Bitbucket, Google has announced the closure of Google Code. Effective today, Google Code is no longer accepting new projects, and it will become read-only in August. After that, tarballs of all project data will be available until June 2016. To help project owners migrate, Google has added an "Export to Github" button to every project.

+ - NIST to offer Accelerometer Calibration Service->

Submitted by yakatz
yakatz writes: While your games probably don't require this level of accuracy, the use of super-accurate accelerometers is growing in the Internet-of-Things. The US National Institutes of Standards and Technology is getting ready to offer a new calibration service, sensitive enough to detect motion over distances as small as a few nanometers and frequencies up to 50,000 Hz.

As for the "pull down mirror", that isn't even remotely new technology. Other vehicles have had those for a decade or more. But of course because America - and the American media especially - love Toyota with a great passion, we regard it as a technological marvel.

Toyota has had it also. Not sure why this implies it is new.

OK. My curiosity got the better of me, so here it is.

First, using his number of 82.5 cubic millimeters for the volume of a Micro SD card, and Wikipedia's 1,134 cubic meters for the cargo volume of an A380 (in freight configuration), I get 13745454545 cards. Using his 20% density reduction, I'll bring that down to 10996363636. 128GB MicroSD cards exist, but they aren't mainstream yet, so let's go with 64GB. The total data capacity of the plane is therefore 610.4 EiB (exbibytes), which Wolfram Alpha helpfully says is about 0.7 times the estimated global IP data traffic per year by 2015, and around 59 times the estimated information content of all human knowledge as of mid-1999.

I looked around to see if I could find anything higher-density than MicroSD, but there isn't really anything. Full-size SD cards are readily available up to 256GB, but they are significantly more than the volume of 4 MicroSD cards. mSATA SSDs are even worse - they are available up to 1 TB, but they are way too big.

I'm sorry, but the best quote from that book is actually this one:

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

In my networks class, we extended the calculation to a 747 full of DVDs (the best we could do at the time). Maybe one of these days, if I have a minute, I'll go back and do an A380 full of flash drives.
