Air gaps are a liability. They do not work as advertised. Covert audio channels have nothing to do with it.
When you put a computer in a faraday cage with an air gap, you still need to computer to have some input and output in order to be useful. So the air gap requires that a human periodically walks into the room and interacts with the machine. At this point, the options for undermining the security of the system have gone up exponentially.
The reality of air gaps is that key signing ceremonies take place with several people packed in the room, while CDs are passed back and forth and put in the machine holding the CSRs, the software and signed certs.
If you instead had a wire to the machine in the room, you could monitor the transactions over the wire. You could ensure a non turing complete language is used in the wire protocol. You can deny humans access. You can apply defense in depth to a wire. No so much to a room full of humans.
It was one example from a study of socioeconomic biases in standardized tests. I can't reference it now because I'm at work. My wife's the one with the PhD in education that knows all the research.
It's a hack to cope with the fact that the browser-server connection doesn't hold state at all well between pages.
It all holds together nicely until you try to make it secure, but establishing a secure session on top of a system that has its fingers in it's ear says "La la lah, I can't hear you, I'm REST, not session based".
I had plenty of opportunity. My father was driving adoption of computers (apples, BBC micros etc.) in the local school district. My mother ran an outfit called SEMERC (Special Education Microelectronics Resource Centre). There were computers around the house, accessible to me from the age of 9. I took to it like a duck to water and 35 years later I'm gainfully employed doing lots and lots of techy shit.
The issue with the opportunity hypothesis is that my sister had exactly the same opportunity, but couldn't give a shit about computers. She became an English teacher.

Even better, school districts and states outsource the testing to test companies that never, ever provide statistical validity or reliability data for the tests, so the performance metrics that are being used to punish teachers bear no relationship to the competence of the teacher.
Oddly, if you look at all the teaching methods that have been well researched and shown to be effective, none of them say anything about how much the teacher is paid. But some of them say a lot about making the teaching comprehensible by the child. E.G. A few years ago, standardized state math test in Oregon had a collection of arithmetic problems based on stories about elevators trips. If you're a child growing up on the Warm Springs reservation in central Oregon, odds are that you've never been in an elevator and may well be generally unfamiliar with the whole concept. So even if you're fine with arithmetic, a wholly unreliable test is applied that labels you as stupid and your teachers incompetent.
The whole level of fail surrounding school testing and 'holding teachers accountable' is so shot through with a specially pungent, stinky type of fail that you might consider that pulling your child from school and putting them in a charter school or homeschool school (essentially a college like school for school age children - sign up for courses and attend them - no social control) would be an improvement. It generally is.
You're making a pretty big leap that it is social pressure and attitudes of grownups that filter out girls from boy dominated topics and boys from girl dominated topics. There are clear gender preferences in many aspects of a child's life. People who performed experiments to provide a gender neutral environment in an attempt to prove it was nurture, not nature that drives these preferences always fail.
Middle school (for those not familiar with US schools, school for age 11/12 through to 14/15 years old) is also the time when hormones hit the hardest and school girls go uniformly bat shit crazy (according to my wife who taught middle school mathematics for a few years before escaping). Claiming it is social pressure is to ignore the much stronger forces that are acting on children's minds in middle school.
BS. Opportunity is exactly what it says on the box. Schools have been offering opportunity for decades. There is and always has been a strong gender bias in the opportunities that children choose to take advantage of when given a free choice.
What is wrong is denying opportunity, so that a motivated children don't get to pursue their muse. Trying to shovel less boys and more girls into a particular subject, that was available anyway is neither enhancing opportunity nor motivating more pupils in any particular direction. The motivation comes from somewhere else.
>How do you as a teacher ensure that at least 40% of your students are girls? Throw out some boys that are interested in programming?
Yes. That's exactly how it works in NCLB. Identify the failing ones and pull them from the class or school before they start affecting your averages. This situation is no different.
>Why the FUCK doesn't Nintendo or Sony build a fucking gamer phone.
The 3G version of the Vita has everything necessary to be a phone, except a phone app. It even has a phone number assigned. This lack of a phone app appears to be deliberate.
Round trip time for an old school EDO DIMM is not the same thing as the burst cycle time of a synchronous dram. It take about the same time to get going, but the data bursts faster and wider.
Often I want a lot of channels, but to capture diagnostic data specifically formatted for output to a diagnostic port on the chip. So I don't need a $100K Agilent mainframe LA setup. I just need a synchronous FIFO that can be triggered that a PC can read.
Since such things are not really out there, you just hack it together with an FPGA. So it's product+FPGA dev board+a few wires+a usb PC connection.
The DFX circuitry is all on chip. You just want to get at it.
B.S. I did not say Jesus didn't exist. I said it is very probable that a miracle casting Jesus born of a virgin never existed. Find me a modern day person that can perform miracles and I'll revise my opinion of a person performing miracles 2000 years ago.

Air gaps are evil.
Right. Two things that won't happen: Me signing an NDA for a Batman movie or me purchasing a Batman movie.
They are often required to sign non reversing engineering requirements and non-review agreements, which is an NDA by another name.
CAD tools are notorious for this.

I don't know a single competent programmer that started programming because someone taught them how. They started programming because they wanted to.
Manipulating teachers isn't going change that outcome.

No. The DOM and REST is why Javascript+DOM+REST is a PITA.

Fuck off. I write in Python, C, SystemVerilog and whatever else suits me. I guess I won't be writing Chrome apps.

It's in the UK. The glorious leader is David Cameron.

What's on my workbench?
1) A PC running VNC
2) A datacenter full of servers loaded with chip design tools
3) A 6 billion dollar fabrication plant.
Oooh. I have one of those.
Oh wait. It's a CFFA, not a CFAA.
