Shannon-Hartley says the theoretical maximum data rate for a channel with AWGN is proportional to bandwidth and the log of signal-to-noise ratio. For an off-the-shelf microphone/speaker pair, I think 16 kHz and 80 dB are probably decen

I think they only care about preventing data flow in one direction while still allowing it in the other. This isn't strictly an air gap, but it fits their use of the term "data diode". The fact that the unidirectional flow of

Writing code _has_ helped me feel better on some bad days. Even looking back at old projects brings me contentment and reassurance sometimes. On its own, it can't provide the happiness that a balanced life can, but craft and achievemen

My wife is also T1 diabetic. In principle, yes, a major airport's medical team should have everything that a diabetic needs to survive. However, depending on the person's blood sugar level at any given moment, it may be necessary

My mother said similar things before her death, and I accepted them with love while privately dismissing them. But since then I've softened a little. I still don't believe in those ideas in a literal, empirical sense, but they h

This blog post[1] may interest you. As you suggested, the workflow seems to be: 1. Try various techniques that might trick the firewalls on both ends to let the connection through. This requires a relay for the initial negotiation only. 2.

>you can get a sport pilots license in as little as 20 hours of training This is not enough training to operate safely, in my opinion. Even in VFR conditions, I think it would be negligent for an instructor to turn a 20-hour pilot loose

I think this means that a previous iteration of this effort had a value of £249,000. The article is mainly about the current iteration, which has some other total value that is presumably larger. It isn't clear how much the current ite

I tried using this a year or two ago—seemed like a really cool idea, and I still think it is—but I couldn't find an actually useful application for it in my life. Not saying there aren't plenty of neat applications out there, but

This sounds fun. Rust is amazing, and I've been playing with it on AVR chips lately. And I spent several summers sailing years ago. Email me if you'd like. Curious to know what you're working on.

I wonder how difficult it would be to implement a language for specifying Factorio factories without worrying about physical layouts. This post provides a lot of good insights into how that could be done. Once a factory is specified, a comp

When I started my last job, I thought I was going to be writing a lot of Python and C. It turned out that the position had a lot more React and TypeScript than I expected, and at first I was annoyed and afraid. I wasn't a frontend deve

I know this joke, but in the version I've heard it's mechanical engineering students instead of programmers, their professors instead of conference participants, and the aircraft itself instead of the flight control software. But

These ideas have almost no empathy, and they frighten me. The world they describe is a dystopia.

I'm interested in trying to determine whether or not someone I know has this disorder by examining their 23andMe data (with their consent, of course). I imagine that it might be possible to write a program that does this for me, but I

Did this system for surface-to-air recovery more or less get its lunch eaten by helicopters? Still, pretty neat.

I agree, at least generally. However, something I've learned is that privacy always has a cost. I wouldn't count on retailers to pay it when most of their customers won't notice or care, and I wouldn't count on governmen

I agree. However, in this case I believe most versions of rm would complain about passing "/" as an argument without also passing "--no-preserve-root", so there's that at least.

I think this is a neat idea, but I suspect it would be more useful as a standalone device than as a wearable. Devices like this could be installed in secure rooms or deployed on the fly in discreet locations with a high rate of success, I&#

Perhaps more interesting to me than UNIVAC itself is the system by which all the weather data it crunched was brought to it in the first place. Without the Internet, how was weather data transmitted across the country? Wireless ground stati

You may be right, but for what it's worth I caution you against equating being early and being smart.
