> To test its adhesive strength, researchers first glued two untreated polytetrafluoroethylene (PTFE) plates by sandwiching molten CyclicFP-fmoc between them and letting it cool at room temperature for 10 min.
Also notable that the glue substance is reusable:
> Remarkably, a simple ethanol wash completely stripped CyclicFP-fmoc from the target PTFE plates, leaving no trace behind. The recovered adhesive proved repeatedly reusable, reliably maintaining its adhesive strength of ~1.2 ± 0.1 MPa across multiple cycles.
Perhaps hot glue guns are going to get an update ;)
As far as I can tell, there is no environmental regulation of how many kilograms of aluminum, silicon, etc. being added to the Earth's atmosphere when a Starlink burns up during re-entry.

Front-end downstream of clicking on a card doesn't seem to work correctly on every reload... but it works sometimes.
Could I put a unique constraint on property `id` of all nodes with label X?
Could I put a constraint that edges of kind A must always go from nodes with label X to nodes with label Y?
What kind of indices can you add?
Will SQLite use them when you do a Cypher query?
Will your Cypher query planner take them into account?
Having done a little more digging, I could find lots and lots of pieces about this topic, but I could not even one coming from a recognizable journalistic source. (Far from the top of search results was a piece that seemed to have some value: it noted the wave of coverage of the purported end of this pact despite the fact that no such pact existed. It also identified a possible connection between pushing this story, which makes the dollar sound endangered, and attempting to promote cryptocurrency.)
Lots of HN commenters taking this at face value. To me, the overall situation looks like an object lesson in basic critical media literacy.
Sounds very cool that cross-plane links are doable, even if they have predictable complications compared to in-plane.
I would have thought that someone would make a big deal (have a press release, e.g.) out of successfully establishing cross-plane links, but maybe it just doesn't seem that impressive to people who already have good enough precise predictive ephemerides or satellite states to make those links in the first place.
Cross-plane optical links would have a trickier tracking problem.
While there's no explicit mention of same-plane vs cross-plane optical links, I assume that the first time people have a public cross-plane optical link, they will make a big deal out of it. :)
The article also mentions that SpaceX would need to do further study before using laser links between satellites and ground stations-- this kind of optical link would require both more angular tracking and probably atmospheric correction as well.
Given that I don't do JavaScript or front-end for work, I mostly run into these things in hobby programming. Given that this is programming for fun, I can voluntarily cut myself off from all the libraries that use other module systems. In this happy little bubble, over time, ES module support has gotten better and I've selected tools / found ways to use tools that work with modules and I rather like it.
Perhaps because I'm less invested in the tools, I evaluate the situation of "tool X doesn't support ES modules" more like "tool X isn't great" and less like "ES modules are bad".
Perhaps it all stems from being a person who genuinely likes JavaScript, has a high affinity for standards, and a relatively low opinion (yes, I'm a snob) of the Node ecosystem?
I love that it uses exactly 1 WebComponent. I love / am vaguely confused that it doesn't read the component's own DOM but instead gets the `.outerHTML`: https://github.com/franciscop/vector-graph/blob/master/index...
I guess that it means that the actual rendering gets fully decoupled from the live, but hidden DOM tree within the WebComponent and that live DOM tree doesn't really matter aside from first render.
Hmm. I think you've specified a bet you are likely to win, but one that's nearly meaningless. Perhaps if you fully lock down all dependency versions your React 16 app will not break, but that's a little more like running an old program in a VM or an emulator than "I can still work and hack on my React 16 app."
A more meaningful bet would be, "can you still develop on a React ZZZ app vs. can you still develop on an app built with web components."
If I got to pick the terms of the bet (to favor my viewpoint XD but also to make it more meaningful), they'd be "would updating a React app to catch up on N years of dependency updates be more or less effort than updating a web-components built app to catch up on N years of dependency updates"; if you keep your web-components built app from having a bunch of weird dependencies, I think the odds are very much in favor of the React app taking more effort to update.
Basically, betting on browser vendors to be less likely to break backwards compatibility than the authors of React.

I agree in general, but knowing that the author is a professor of Economics at George Mason University, I am less surprised.
My perception is that Econ department seems to have a lot of room for unusual ideas within the field and rather a lot of professors who hold forth or publish on topics that overlap to a variable degree with economics-- like how this post addresses questions of punishment and moral philosophy with what appear to be the tools of economics.

What you describe sounds more to me like the ""10X engineer"" (with extra scare quotes for good measure).
Many people have been skeptical of the idea of the 10X engineer. One take is that if your normal engineers are less than 1/10th as productive as another engineer and all of them are merely human beings, there might be some common organizational problems that your normal engineers are all being stymied by. Another take is that your 10X engineers can only achieve their high level of productivity through taking on more technical debt than others understand or would tolerate, leaving messes behind for the eventual maintainers to fix.
Very large organizations need technical solutions to organizational problems, especially when there are many loosely coupled teams interacting in one way or another.
Taking any of the more accurate measurements of body composition requires effort, unlike BMI. It's easy and lazy and not yet acknowledged as an ineffective practice so doctors do it. It's also not always wrong, just because BMI and obesity do correlate.
> Julia has no formal notion of interfaces, generic functions tend to leave their semantics unspecified in edge cases, and the nature of many common implicit interfaces has not been made precise (for example, there is no agreement in the Julia community on what a number is).
> The Julia community is full of capable and talented people who are generous with their time, work, and expertise. But systemic problems like this can rarely be solved from the bottom up, and my sense is that the project leadership does not agree that there is a serious correctness problem. They accept the existence of individual isolated issues, but not the pattern that those issues imply.
It sounds like the cultural standard for writing libraries is, "works good enough for users like me" which should be good if you are using things the same way as the authors. Writing good tests for numerics is hard and grueling; testing numerics or numerics-like code is not nearly as fun or productive-feeling as using numerics to get shit done, so it all makes sense to me.
