check out the contactless vital sign sensors from NorbertHealth.com that has SpO2, BP, PRV, temp, etc.
All operations in Class A airspace, which goes from 18,000 feet to 60,0000, is conducted under instrument flight rules, which means flight plan and clearance, transponder, two-way radio, and (now) ADS-B. read this account of a SR-71 Blackbird http://b.johnwurth.com/aspen-20/
Re:Performance of green threads and why it matters on Monday May 09, 2016 @08:30AM (#11659245)
programs that use lots of signals and/or asynchronous completion of IO or timers ("completions")

completions create all sorts of concurrency problems because they are delivered to the program without any concurrency protection, and writing such protection correctly turns out to be non-trivial.

By delivering completions into coroutines, you gain all the concurrency protection that is offered by the green threads, without having to write it from scratch.

Re:Performance of green threads and why it matters on Monday May 09, 2016 @08:12AM (#11659155)
we built a green threads implementation for VAX/VMS in 1984 with pre-allocated stacks because performance. the key is to put guard pages in between the stacks to protect from stack overruns.

Re:Some thoughts on when NYC last opened new subway stations on Thursday March 17, 2016 @05:13PM (#11307657)
The cluelessness of this article is beyond words.

New York City has one of the most amazing transit systems of any city in the world, and most of it is at least 100 years old.

By focusing on stops and forgetting to mention the dozens of large projects taking place in the NYC transit system, he makes it sound like nothing is changing.

Here's just a small list off the top of my head:

1. new Penn Station

2. Yes the 7 train to Hudson Yards

3. Yes, the 2d avenue subway (which has been in the offing for 100 years)

4. new East River tunnels

5. new ferry system (including 18 new ferries announced today)

6. new Select Bus Service

7. new New Jersey tunnels

8. repairing East River Bridges

9. new tunnels for LIRR service to Penn Station

the AI and law movement began more than 40 years ago. There's an AI and law journal, a bi-annual international conference (ICAIL) and tons of other work (such as LDRI from the UK National Archives and the automated legal reasoning research from Stanford, CMU, and MIT.

most companies don't even bother calling or writing you to tell you 'no'. or they string you along endlessly until you get tired of asking, or you feel like you're becoming a pain.

Re:Physicists Detect Gravitational Waves, Proving Einstein Right on Thursday February 11, 2016 @04:56PM (#11083601)
Then you should have concentrated on theoretical physics instead of experimental?
Re:Physicists Detect Gravitational Waves, Proving Einstein Right on Thursday February 11, 2016 @04:55PM (#11083587)
And there is a third which was offline at the time, and 2 more being worked on. This is no the last experiment.

Re:Secret US flight flew over Scottish airspace to capture Snowden on Wednesday February 03, 2016 @08:18PM (#11031320)
the G-V is certified for ETOPS -- extended twin-engine overwater operations. Second, there's no "gliding" involved. ETOPS flight plans are designed for single engine operation. That floating seat cushion is for when both engines fail.

the jet in question is a Gulfstream G-V. Its a very fancy passenger, long-range passenger jet

Even in Class C in UK airspace, you need a clearance.
