I have a relatively ancient 8086 I still use from time to time with plain text files and a simple editor.
It provides a distraction-free environment for writing.
Save it to a 720kb floppy that my linux box can still read, and move it to a "modern" system for editing and such.
They're looking at it wrong. The signs are operable by the flight crew.
Given: Aircraft power is on, signs are on. Aircraft power is off, signs are off. Aircraft power is operable by the flight crew.
Therefore: Signs are operable by the flight crew.
In addition to the aircraft main power system(s), there's almost certainly a circuit-breaker that would turn the signs off. It might turn other things off as well, and circuit-breakers are not generally designed to be used regularly as switches, but there's a circuit breaker in reach of the crew that would turn those signs off.

I'll grant there may be a 4th staff member not (yet) listed on their webpage, but their organization seems a little top-heavy.
That's not worse, that's an outstanding mental image.
To pick on my favorite example,
Many years ago, my univerity's choice of calculus book also had the solutions to half the problems (evens or odds, doesn't really matter).
Department policy was also one of "we won't provide you the correct answers" even after an assignment had been turned in because the book was used for multiple years. The publisher had a new edition every year, but the university stuck with the same book because it was used for Calculus I, II, and III, which for most students was 3 or 4 semesters between starting I and finishing III, usually due to a scheduling conflict requiring a semester off between them, or because they had to repeat Calc II since the math department's selection of instructors was particularly bad for that course.
Those same (usually bad) instructors were all too happy to follow the department policy and not provide any feedback other than "correct" or "incorrect".
On the other hand, the university book store carried, and put on the shelf right next to the calculus book, the publisher's "teacher's solution guide", in two very reasonably priced volumes, which had the answers for the other half of the problem sets, as well as the step-by-step process for most of them, which was the valuable part, as you could see where you were erring.
Math department policy was that you weren't allowed to have those, either.
You can guess how well that policy was followed.
Those that put the effort in and learned the material did well. Those that just copied from the solutions book and turned it in did not.
Good catch. Curiosity got me and I focused on the distance aspect, missing the forest for the trees, so to speak.
Assuming that they're referring to decimal degree notation, and not Degrees-Minutes-Seconds, and that the location is correct, and ignoring the spheroid vs perfect sphere issues: about 11.1 meters (36.4 ft).

If it's DMS, again assuming location is correct, ignoring spheroid vs sphere: something between 80 and 100 ft (24.4 - 30.48 meters).

Trivially defeated with a boot disk and ResEdit.
Breaking things with ResEdit was pretty much my jr. high school hobby. It took a bit before I figured out how to restore things when I was done.
Head "tech" guy in the building eventually figured out it was me, showed me a few things and ended up just giving me an un-limited login and a few rules. Also taught me how to intelligently use ResEdit instead of the brute-force method(s) I was used to.
First, I appreciate the answer. I didn't know about the "no large bodies of water" requirement. When then leads me to ask, what's a "large" body of water?
Second, and I'm not trying to be snarky, just trying to understand: What is the limit on size? I understand there's a point where physically building and maintaining it isn't practical, but is still theoretically possible.
As for defeating the point, I'll admit I only somewhat understand that argument.
As far as I understand -- and I'll readily admit I do not have a great understanding -- the whole concept of the eruv is specifically designed to "defeat the point" of another rule (or set of rules).
Why is "defeating the point" considered to be "ok" or not "ok" based on scale?
Likewise, if "defeating the point" is wrong, why is it not always wrong?
Again, my intention is to understand, not to be snarky or otherwise inappropriate about it, and I'll apologize in advance if my questions cross lines I was unaware of.
To which I ask: Why not place a small loop of (wire, cord, thread, whatever qualifies) on the ground in a park somewhere. Then define "outside" and "inside" the other way 'round from "normal", thus making very-nearly the entirety of the earth "inside", and the very small portion "outside".
It seems logical to me, and I've never heard a reason it can't be done other than "that's defeating the point."
Which I admit, it entirely is, but I don't see it as any more "wrong" than encircling entire cities, and it's a whole lot simpler to maintain.
Some states allow "one party consent" to recordings of communications (ie, phone calls). Extending that, as long as Company A is aware of FB's practices, then your wishes are irrelevant as far as the law is concerned.
I have no idea what California's laws are regarding the matter, or the laws governing any of the other participants. I'm just speaking in the general case, that some states allow it, and the argument that could be made.
All I see when I look at the JAXA logo is the blue Lockheed Martin star that they've used since the mid 90s, if not earlier.
I had a similar problem, several constraints (dozen or so, iirc), data set of a few thousand items.
I thought about finding an elegant solution, but in the end decided that just doing a (psuedo-)random selection of the remaining set and then running through the resulting ordered list checking each one for all the constraints (ie, random sort). As soon as it failed a hard constraint, or failed > x soft constraints, toss the list and do another random sort.
Ugly, but it worked. Chose this solution because 1) I knew how big the data set would be, and I knew it would not change size enough to matter; 2) The other, very jr developer could understand the method; 3) The constraints, while semi-complex, were simple to check; 4) would be needed once or twice a year, could run completely off-line, and could be started well in advance of when it was needed; 5) and finally computers are fast & cheap, while my time is finite and valuable
As a result, the decision that "brute force" running on any available workstation for a weekend was an acceptable solution. In it's lifetime, I think the longest time it took to find an acceptable solution was a few hundred thousand sorts, finished in a few minutes.
It's now been retired as the program it supported went away.
I wish I'd had the time to explore better, more proper solutions, but at the time, quick and dirty and done was more important.
Regarding other software / platforms, HTTP GET seems easy enough to work with.
My issue with wifi is really just a matter of too-many-networks and interference making it a bad solution for me.
But I understand the appeal of the ESP8266 (and the rest of that family of chips) and don't blame you one bit. IIRC it has a serial port on a couple of pins, so that's another comm option.
In any case, I look forward to seeing your progress. Good luck!
Wish it had more details: Rate(s) of rotation, load capacities -- including windloading, etc.
Also rather wish it didn't rely on wifi/android, but that's mostly because I don't use anything android based, and don't run any wifi on the home network anymore.
All in all though, it's still a pretty nice looking little az-el rotator. With different control software, it might also be a useful little addition to give your static security camera a bit of extra capability without breaking the bank.
They did a lot of the "rails to trails" stuff around here as well, but the underlying deal is that it's all technically land-banked and the railroads can claim it back at basically any time as long as it gets put to active use.
There's a station local to me with above ground tanks. They're in an area that flood regularly, which is why the tanks aren't buried.
I've never noticed a measurable difference when filling up the 20 gallon tank in the truck.
I suspect you'd have to buy a LOT to make a meaningful difference.
The theory is that they can reduce the supersonic shockwave to the point where supersonic flight over populated areas can be legalized again.
I grew up with the "Save a Connie"[1] plane and organization in my back yard, so to speak -- we lived about 6 miles from the KC downtown airport. I remember dad taking me down to the airport to sit on the river levee and watch the it arrive when they ferried it to KC. After that, I think I attended every public event they hosted between the plane's arrival and the change to the Airline History Museum.
I think I still have a bunch of their airshow flyers and other give-aways squirreled away in the basement somewhere.
Thanks for the interesting trip down memory lane.
Many universities these days have students scattered around the world in various distance education programs, or have students/staff/faculty at various other locations doing research in collaboration with other labs, facilities, etc.
Then there are their research partners, which again may be scattered around the world, etc.
So, no not customers in the traditional sense, but they depend on University services, and many of them are paying for the privilege.
A few years ago, I placed an order from a small company on the east coast, to be shipped via USPS parcel post (ie, the cheapest and slowest option possible, though the company does pay the extra for tracking). In a rush, I fat-fingered the zip code. To compound the error, after submitting the order, their shipping software helpfully "fixed" the bad zip code by adjusting the city and state to match.
The next day, when they sent the shipping confirmation and tracking email, I saw the error. Of course, contacting them was too late; they did ask that I give the post office time to sort it out but were happy to send another one if it was time critical. I opted to wait as the initial mistake was mine, not theirs.
The package arrived a day later than expected, having gone to the small town in the wrong state, been kicked back as "no such address", sent to some big USPS facility in Chicago where they apparently figured out where it should go, manually crossed out the bad city/state/zip and wrote a correct one in and then came straight to me via the local post office, skipping the nearby sorting center that most packages go through.
I don't know how they pulled that one off, especially in a pre-christmas shipping glut, and without the package ever having had the correct address on it until someone working for the postal service figured it out and fixed it. Having a unique name probably helps, as does having a fairly unique street address, but I'm still impressed it didn't just get tossed into the dead-letter pile.
Living in the middle of the country, the post office's abilities are almost magic. Need to send a letter anywhere in the US? Two or three days, for a few cents (no idea what it costs now, I bought a few rolls of "forever" stamps at 40 cents apiece). Need to ship a package? USPS is often cheaper than UPS ground, nearly always cheaper than FedEx ground, and faster than either of them at still only two or three days. Same goes for receiving mail or packages.
Quality of service of all three, I recognize, varies with location and people involved. Around here though, it is damn hard to beat the post office.
Because Boris is UK-Trump? (said only semi-seriously, I don't follow UK politics close enough to know for sure how good the comparison is)
I suspect it's a matter of the "special relationship" the US and UK have had for decades; Trump doesn't want to be seen as the one throwing our UK friends under the bus, especially with the promises he made during the lead-up to and implementation of Brexit.
Drivers Ed was an optional summer course in my district, and did include an on-road component. Not required at all (although the insurance company gave a discount for completing it).
HS graduation requirements vary (in some cases, much more than you would think) between districts. Usually, each town/city has its own district -- in rural areas a district may span many towns, in more urban areas, you may have more than one district in a single city. There are state guidelines, but we also have 50 different states. Federal guidelines are pretty sparse, and often only enforced by accepting funding -- don't take their money and you don't have to play by their rules.
I suspect that there is no blanket statement about the US public school system that will hold true nationwide (except, perhaps "it could be better" or "it makes no sense").
The reaction to not having a license is probably simply due to 60+ years of "The American Dream" for a kid was having their own car and the freedom^tm that came with it, and the simple fact that in the majority of the country, public transportation is crap, and our cities are not designed around walking. So a car, and license, is pretty much a requirement.
Thank you, it looks very promising, and I like the host-it-yourself aspect.
Is there a current (preferably free, ideally open-source) replacement that is as easy to use as Hamachi was?
I've got a truck (an older Tacoma) and too many hobbies that make it hard to give up, so I'll likely always have a truck.
If Tesla had introduced a factory version of Simone's, I'd be screaming at them to shut up and take my money.
This thing...I'm sorry, I can't get over the styling. I love the numbers, and don't even find the pricing to be too horrible, but there's no away I'll have something that looks like that. Maybe Tesla truck 2.0 will be worth looking at.
A lot of the midwest (or the great plains) is devoted to feed corn and corn for ethanol, wheat, and soybeans. It's not california where you'll find fields of lettuce, for example.
With that said, there's no shortage of small farms growing most anything that can be grown in the area, but they tend to not be exporting anything beyond the local farmers market.
He's not landing it back at the pad or anything like that, just wherever it happens to be coming down at. Then keep it vertical(ish), keep it from moving too fast sideways or it'll tip over (again, stability, not guidance), and wherever it touches down, it touches down.
My memory might be wrong, but wasn't the Brooklyn Bridge built when steel was still a relatively new thing? Its properties weren't entirely understood, or even well understood, so as a result, it was tremendously over-built.
Now, everything is about how little material you can use, how close to the minimums you can get and still maintain a theoretical factor of safety. The problem is that in doing so, small mistakes have a much bigger impact.
If you can open it enough to cut the led, why not just wrap the led in tape while you've got it open? That should cut down on the light leakage through the usb ports.
