Founder/CEO of Albedo here. We published a detailed write-up of our first VLEO satellite mission (Clarity-1) — including imagery, what worked, what broke, and learnings we're taking forward. Happy to answer questions.

The diffraction limit (under 1.22 h* lambda/d) of a 1m optic at 250km in visible light is about 17cm. How can you achieve 10cm resolution?

> In 1988, when Larson visited Goodall's research facility in Tanzania,[115] he was attacked by a chimpanzee named Frodo.

That last sentence is missing from the Wikipedia page. What is the source on it?

It makes me wonder: Would an airline that drastically simplified its fares be more likely to appear in flight search results?

Simplifying the fares would make it less computationally expensive and, in theory, could take fewer steps to answer a flight planning query.

Imagine a flight search planner that, say, fanned out N airline-specific workers when handling a planning query and then displayed to the user whatever results it got back within some time limit. If FooAir had simple fares, the FooAir searcher would likely run faster than searchers for other airlines. Thus it would be more likely to return results for more queries, assuming the deadline is fairly tight because of usability metrics. (People don't tend to stick around waiting for slow results.)

At least a few years ago (~2014), the fare search was actually nearly instant, but all major airfare search sites added a delay because customers had the impression they were getting a better deal when they had to wait. It seems like the delay has been dialed back lately.

I thought it was interesting when I looked up US gyms that they require a belay test.

In Austria, the gyms I went to you just had to sign a form that you know how to climb top-rope, lead, and how to belay.

I’m not sure why people are making a big deal of it. At my gym it took maybe 3 minutes. You tie a knot and show you know how to take up slack. And it only needs to be done once.

There is a second test for lead but most people take a class and get the lead card during the class.

Don't see how it could introduce bugs. The point of replacing a variable is precisely to make a value that is no longer needed inaccessible. If anything introducing new variables with new names has the potential to introduce subtle bugs since someone could mistakenly use one of the variables that is no longer valid or no longer needed.
sjburt · a year ago
When you are modifying a long closure and don’t notice that you are shadowing a variable that is used later.

I know “use shorter functions” but tell that to my coworkers.

My least favorite is when I relent and get on their call, and after 30 minutes of answering their questions, they say "OK, next step is we'll schedule another call with our product specialist, because i'm just a sales guy and i didn't really understand most of that."
sjburt · a year ago
The worst part is that the sales person has to go back and pitch their team on whether it’s worth their time to get back to you.

Really curious about this:

Anyone know what this was or use it?

That's more a language issue than a number issue. 1000% is already a factor, it's literally the number 10.

The problem is that the whole sentence doesn't make sense with a number there. "Company claims 10 price hike drove it from VMware..."

sjburt · a year ago
“10x price hike” would have been totally clear. “Factor of 10 price hike” would probably be a formal way to say it.

Are there any benefits in using Raspberry Pi OS (the continuation of Raspbian), over unmodified Debian? Are the support windows different?
sjburt · a year ago
The Debian images (https://raspi.debian.net/) haven't been updated recently and don't support the Pi 5 at all. And support for other hardware is inconsistent.
