Agreed. The story is great, too. A really interesting logistical challenge that arose from unusual circumstances.
There's probably something to be said for the fact that TDC is a small, remote community, so it shouldn't be surprising that its website is reminiscent of a smaller, more communal web... but I'm not going to try to read too much into it and let the story stand on its own.
Until recently TDC had a very slow FCDO satellite link that required their website to be quite basic in order to actually be viewable on computers on the island.
They now have a fast Starlink connection, but I’m glad they’ve kept the website as it is.
Offline PWA sites are very limited on iOS. If you force close Safari, look at your phone funny, or don’t visit the site regularly, the cache is cleared and you are stuck at a loading screen until you have internet again.
That’s what forced me to finally bite the bullet and pay Apple yearly so I could develop an app for my friends and I to use. Would have much rather kept it as a PWA.
The one takeaway I got from my engineering ethics class in college was that everyone has different morals. Debating if something is “moral” or not is useless. Education on a subject is useful, but once someone understands your point of view and still thinks it’s within/outside their morals, there’s nothing more to discuss.
Same. My work laptop has a touch screen and every now and then, when I remember that fact, I’ll use it to scroll through a few pages of a PDF. It gives me a chuckle because it’s so inefficient and inaccurate… then I immediately revert to my click-wheel mouse.
I really don’t want to work for the defense industry, but I have to admit that they do have very fun problems to solve. You know there are people at NRO who are dedicated to ship tracking via satellite. I assume they can easily track ships without cloud cover, but how do they do it when it’s cloudy? Heat signatures? Synthetic Aperture Radar? Wake detection?
For the first one, just look at wikipedia lists of government says that fly as little triangular constellations, like Yaogan 9A, 9B, 9C on this list: https://en.wikipedia.org/wiki/Yaogan
Those are ELINT birds that use multilateration to spot emitters globally.
SAR can spot wakes far, far, larger than ships using the same techniques as SAR measuring ground erosion, etc.
I'd be mildly surprised if they not using SAR for this all the time, not only during cloud cover. The Soviet Union was using radar satellites (the RORSATs) to track carriers decades ago.
Bandwidth and processing are substantial bottlenecks with SAR; Only targeted and stationary applications have been broadly useful so far, and more focus has been put on planes than satellites for this. SAR is not as simple as taking a static image with a fixed resolution, your sensing window has got a target velocity and distance in mind and the antenna and processing needs to be tuned for that.
I would think that medium and high orbit optical tracking (daytime, cloudless sky) is probably used, because with video you can reasonably track subpixel targets if they're high contrast, without a lot of data transmission requirements.

I'm not sure why you assume this, this is factually incorrect. Satellite based SAR has been successfully used for civilian ship detection applications (traffic management, illegal fishing, smuggling detection, etc) for over three decades. I am sure its military use goes back much further.

No? SAR satellites take thousands of SAR images of stationary scenes every day. It's true that object motion in the scene introduces artifacts, specifically displacement from true position - this is often called the "train off track" phenomenon, as a train moving at speed when viewed with SAR from the right angle will look like it's driving through the adjacent field rather than on the track. However, this isn't a significant problem, and can actually be useful in some situations (eg: looking at how far a ship is deflected from its wake to estimate its speed).
40 years ago the USN was working on using SAR with a elliptical kalmann filter to detect _submarine_ wakes. I assume things haven't digressed since then.
IME here in Colorado, a lot of them pay as well, or better, than run of the mill tech companies. I suspect the AI and "FAANG" companies may pay more, but I personally wouldn't work for any of those. In any case, I'd take $160k in Colorado over $240k in California any day.
And the problems are definitely a lot more interesting.
That’s Simon’s goal. “All I’ve ever wanted from life is a genuinely great SVG vector illustration of a pelican riding a bicycle. My dastardly multi-year plan is to trick multiple AI labs into investing vast resources to cheat at my benchmark until I get one.”
