AWS for sure (Elemental maybe?), but could also be Ring.
procflora··on US axes website for reporting human rights abuses by US-armed foreign forces
Indeed, the recent trend of the US government itself posting videos of the drone murders of Venezuelans stands in real stark contrast to how that was handled just 15 years ago.
procflora··on Astronomers 'image' a mysterious dark object in the distant Universe
In what way is dark matter not a phenomenon? Just because we don't know what it is doesn't make it a noumenon.
procflora··on 60 years after Gemini, newly processed images reveal details
To take many exposures of the same scene and average the pixel values with the corresponding pixels from all the exposures. This increases the SNR and dynamic range, but naturally doesn't work very well if your subject isn't static. It doesn't increase the resolution of the image though.

For the 16mm movie cameras in this case, they probably selected frames from rigidly mounted cameras with little subject motion to get a good result out of it. Glenn strapped in tight in his tiny cockpit probably provided them with a decent number of frames they could stack without introducing much motion blur. In fact, you can see a bit of blurring at the end of one of the white straps center frame in that shot: https://cdn.arstechnica.net/wp-content/uploads/2025/09/03b-G...

It's a pretty common technique in astrophotography. Here's a page that goes into some more detail in that context: https://clarkvision.com/articles/image-stacking-methods/

I'd say laundry is more Sisyphean than Promethean in my experience.
procflora··on Why you can't color calibrate deep space photos
I'm no expert either, I just think they look neat. But from what I know it's primarily the nearby star or star cluster illuminating them, so yes it'd be distinct. Also there are mixed emission and reflection nebulae so technically I suppose they reflect some of the light from the emissive portions, though I'm sure it's a tiny contribution.
procflora··on Why you can't color calibrate deep space photos
Don't forget my fav, the humble reflection nebula. Of course there are always emissive stars in the background of any image of one so the point is moot. But still, there are a few hundred! :D
procflora··on The vibe coder's career path is doomed
Great example!

Another historical example I find myself thinking about is the huge number of objects that moved into a disposable category in the last century or so. What used to be built entirely by skilled hands is now the prerogative of the machine and thus a certain base level of maintainability is no longer guaranteed in even the worst-designed widget.

Yes, AI will mean more software is "written" than before, but more will be thrown away too. The allure of the re-write is nothing new, but now we'll do it not because we think we can do it better the second time, but because the original is too broken to keep using and starting over is just so much cheaper.

Soon at CRUD App HQ (if not already): "Last year's pg_dump is this year's prompt."

procflora··on No GPS required: our app can now locate underground trains
The thing I specifically paid for (that Google Maps doesn't seem to offer) is answering the question "what transit lines/stops are nearby and how soon will a service arrive at the stop?" Last I looked they limit the number of lines shown in this way for freemium users.

If you're just putting in a destination and getting a fastest route (much like you'd do in Google Maps), then I didn't see much benefit to the premium version.

For anyone who's read the book and played the game, a question. I have done neither but bought both last year for a rainy weekend's fun. Anybody have strong feelings about which I should start with?

procflora··on The Seal Failure in the SRB That Doomed Challenger (2021)
True indeed, but it's important to not lose the uncertainly they had at the time, and the degree of o-ring failure being not so binary.

According to what I recall of Allan McDonald's version of things, they had a good amount of data that colder temperatures meant worse sealing performance from the o-rings (soot making its way past the first o-ring and in some cases damaging the second, basically). Like you said, it was a well-known issue in some circles. They also knew the Challenger launch the next morning would be very cold indeed, something wild like at or just above freezing, I think.

The engineers at Thiokol raised their concerns and were asked what a safe temperature to launch is and said something like 53F, basing this on the fact that a previous launch at that temp was successful. NASA (and Thiokol) management balked at this because the booster's certified minimum launch temp was something lower like 30 or 40F. Then they basically asked them to prove it would catastrophically fail at the temperatures expected the next morning, which they couldn't conclusively do since they didn't have the data to back it up. Management reversed the no-go recommendation based on this.

So yes, the o-rings performed as expected insofar as colder = worse, but it was a matter of how much worse at temperatures lower than any successful previous launch.

procflora··on The physics of airplane flight
Depends what we mean by grade school. For young kids (and honestly most adults) I don't think you need much more than this: "A wing, or anything that sends air moving past it down toward the ground will cause some lift (a push toward the sky), but also some drag (a push on your front toward your back). How much of each depends on the shape of the wing and how it's moving through the air. Really good wings cause a lot of lift without a lot of drag, which is good for not using a lot of fuel to get where you're going or for going really fast."

procflora··on X is justifiably slow (2022)
No doubt I'm picking an easy target here, but it takes like 700 ms to switch back and forth from the Chat tab to the Calendar tab in the Teams desktop client on my boring work-issued laptop (i.e. commodity hardware). This is repeatable, first time, every time. It doesn't even bother to animate anything or give feedback that a UI interaction has occurred until 500+ ms after the click.

Some things do run very quickly, for sure, but so many of the high touch pieces of code out there from big name corps have some of the worst performance. Hundreds of millions of people use Teams, and many of them use it a lot throughout the day. You must just be getting lucky in what apps you use on a regular basis.

Wow, that tweet they link to with a super punched in shot looks really really bad! Hard to believe Cameron thought this looked better than just a normal 4k transfer, yikes. Was really looking forward to a UHD release of The Abyss but now I'm not so sure...

Isn't this what the "safety number" in Signal is for? Obviously you are still trusting many other things there (the client software, OS, hardware, whatever out of band method you use to compare the numbers, etc.), but I thought the safety number pretty much addresses the MITM concern specifically, if you bother to check it.
procflora··on More misdrilled holes on 737 MAX in latest setback
I'm not sure about this year, but here is an article from 2020 between the MAX crashes about that very thing. https://www.seattletimes.com/business/boeing-aerospace/boein...

Ed Pierson, a Boeing whistleblower on quality, has also commented on similar efforts by the company a couple of months later. https://www.edpierson.com/removal-of-quality-control-inspect...

procflora··on Boeing withdraws bid for safety exemption for Boeing 737 MAX 7
Another armchair pilot here, also recommending Mentour Pilot's channel, but hopefully I can summarize it well enough.

In this case no, because the way the MCAS system operated was to actuate the stabilizer trim which changes the angle of the entire huge tail plane (the horizontal part of the tail). For the most part the yoke controls the elevator (a smaller flap on the trailing edge of the tail plane), so the pitch control authority available in the yoke movement is not enough to override the adjustment to the tail plane trim MCAS was making.

Once MCAS moved the trim far enough, you couldn't raise the nose with the yoke alone. To correct it, pilots needed to deactivate the trim adjustment motor ("stab trim cut-out" you might have heard about) and manually re-trim the tail plane by folding out a literal crank and spinning a wheel by their legs in the cockpit[1]. The concept of doing this was not new with the MAX (similar procedures around trim system malfunctions existed), but what was new was that MCAS existed in the first place, that it could repeatedly activate if the erroneous inputs were still present, and that it could move the trim quite far before pilots realized what was happening. As I understand it that is pretty different than a traditional runaway trim malfunction for which they'd had training for. I believe that looks more like a stuck switch making a constant movement of the trim until you hit the cut-out. If you cut it back in, either it immediately starts moving again and you know you have a problem or it doesn't and leaves you wondering.

procflora··on Tell HN: Postman update removes all your stuff if you refuse to create account
And if JMeter just isn't quite doing it for you, turn the dial back another few years and experience the joy of the MDI GUI provided by SoapUI. You too can experience the thrills of getting to tweak JVM memory options so it doesn't crash when you try to load a particularly large and unwieldly industry-specific WSDL for an interface standard that undergirds major national infrastructure.

Oh and, it actually does do OpenAPI specs for REST and even mock services and all that, so I'm delighted to share that it's actually relevant to this post! :^) What are you waiting for?

procflora··on Unity plan pricing and packaging updates
I think a lot of people are just fundamentally rejecting the structure of a deal like that. The numbers will matter a lot to individual org's decisions but at least to me the emotional reaction here is unrelated to the specifics of the thresholds and rates. It's just "game engine company should not be doing that."

Probably true since it doesn't appear like they're a game engine company any more. The enshittification machine is rumbling to life.

procflora··on How should AI systems behave, and who should decide?
I would say that there is generally a notion that a machine should be designed in a way that minimizes harm even when it is misused, especially if it is intended to be used by the general public. I don't know if you agree with that, but I would say OpenAI seems to, at least superficially.
