My enlightening moment about general relativity: apples do not fall on the ground, instead, the earth is inflating, and the inflation of the earth is accelerating at 9.8 m/s^2. Eventually, the ground catches the apple.

Of course, you are going to tell me that the earth is not inflating, obviously, because it is still the same size after so many years.

But here is the trick: the earth is inflating at the same rate as spacetime contracts. If the earth didn't inflate, the contraction of spacetime would have collapsed it into a black hole.

Note: It is related to Einstein's elevator thought experiment. Here, the inflating earth replaces the rocket powered elevator.

Note 2: If the idea of an inflating earth bothers you, I suggest you start considering that the earth is flat, seriously! Flat Earthers took Einstein's thought experiment quite literally and consider the Earth to be a disk that is continuously accelerated upwards. And in fact, if free fall trajectories were parabolic, that would be the correct explanations. In reality, because the earth is not flat, free fall trajectories are elliptic, though it is only apparent on a large scale.

Well that was fascinating to see, and there were many more photos than I expected (especially so given that they're in color).

If anyone would like to look at much older photographs of Russia that go back some 40 or so years earlier to the Russian Empire before World War I, the 1917 Revolution and communism, then it's worth looking at the remarkable (and marvelous) color—yes real color—photographs of Sergey Prokudin-Gorsky: https://en.wikipedia.org/wiki/Sergey_Prokudin-Gorsky

The Library of Congress has a wonderful collection of Prokudin-Gorsky's photographs and they've been excellently scanned at a high resolution that's not far from the Nyquist limit, which means they're about as good a reproduction as is possible.

I'm curious, how does the "gravity is not a force" viewpoint relate to the hypothesized graviton particle [1]?

Are they incompatible viewpoints, or just different perspectives on the same thing? (E.g. are gravitons hypothesized to disappear depending on frame of reference?)

I'm assuming they're incompatible (that we need the theory of everything [2] to reconcile them) but would love to know if there's something I'm missing.

Data portability, yes. No big argument there. Back-end interoperability, yes. No more locking out TweetDeck, and common applications for all message transports.

In particular, back-end interoperability needs to be mandatory for Internet of Things stuff. The lifespan of a cloud service is short, maybe 5 years. That's a big problem for house components.

Delegability needs thought. There's bots. There's Snooping as a Service. Technically, back-end interoperabilty implies the ability to delegate. It's more of a contractual issue. Can a service forbid it? Intermediaries and aggregators have their own headaches.

It's manipulative both in the narrative sense (they're preaching to the choir) but also in a sense the commenter made - 'like they do in Vegas'.

The big focus on the 'head only' now on CNN, because that's more engaging - personalities who are almost always 7.5/10 - i.e. nice to look at but not ultra-attractive, the ability to appear 'just credible enough in tone and disposition and yet also empathetic' - that posture is important. And then background, the overlays - it's designed like the environment in Vegas.

Go to CNN.com right now and let the ad for Cuomo's show run - listen to the words he is using, listen to the music, the specific text that they overlay. They are communicating "It's panic time in America, is your heart racing? Because this is so important, and we have the 'Truth' for you here, tune in at 8pm".

These are all generally intelligent, well intentioned people, but the ultra focus on eyeballs and attention really hurts credibility.

We already have that technological arms-race, and users already win. Just look at the continuing existence of "youtube-dl" for example.

Communication is hard.

The Socratic approach is not flawed in and of itself, and works great assuming both parties share a common understanding on the purpose of the conversation. Often, that is not the case.

That's a great quote, but I would characterize what's happening now as 'Narrative Propaganda' in that, there is no authoritative source dictating the terms, but a gaggle of groups fixing the language, narrative, establishing the 'Overton Window' of what is acceptable to talk about - and anyone who has reasonable arguments against said narrative is just suppressed.

Interesting, but I don't buy it. The existence of "youtube-dl" and scraping tools shows that, actually, it's the competitors who usually win.

The fact is, if a service works for users at all, it's never going to be terribly difficult to scrape. That's the whole point of why it's ultimately far more beneficial for users and competitors.

I presented an argument that your point is irrelevant to the discussion, and you provided no meaningful counter-argument in response.
If you choose to view the universe in one particular coordinate system (e.g. one centred on your eyes), then you'll see some things mysteriously happening. For example, you might find that if you release something from your hand, it will mysteriously move towards your feet. Eventually you'll realise that a bunch of things can cause things to mysteriously move, and you'll start using the word "force" to describe "tendency to mysteriously move".

But some of these forces are not observed by other people who are watching; they arise as by-products of the fact that you are the one doing the measuring. For example, if you're falling in a lift, you won't observe the force that causes a ball to fall towards your feet; but I, standing on the ground outside the lift, will observe that actually you and the ball and the lift are subject to this force.

In fact there's an underlying reality which we can't directly observe but which we can infer from the paths of objects. That reality is a curved spacetime, not a flat one (as it appears to be). This curvature means that "straight line" is actually not quite what you're used to; things follow straight lines, but those straight lines don't look straight to us, because of the underlying space's curvature: we can't see the whole of spacetime, only small segments of it, so we can't see enough to get a proper sense of the curvature. But since our limited frames of reference have their own notion of "straight line" which is incompatible with that of the global spacetime, we observe a mysterious tendency of things to deviate from what we think is the straight line they should be following.

So gravity "is a force": it's a mysterious tendency of things to move, because we are limited in what we can see and our own observation frames are subtly incompatible with the global structure. But it's also "not a force": if we were somehow able to take a fully global view of the universe, there would be no mysterious movement, only a huge number of things moving at exactly the same speed in perfect straight lines through a curved spacetime. (Assuming General Relativity is 100% accurate.)

This all depends on where you draw the lines.

One could argue that nothing really new has happened since digital audio, video, computing and communication - all technologies that are 50years old.

All that has happened is that they got cheaper, faster, smaller. Most certainly, a16z has invested mostly in startups that just fall into this category and very little in building fundamental tech.
I see several people have posed about OpenProject on HN, but never before made it to the front page. Good to see it up there now.
ClickUp and Jira both fit your description.

The problem with software for software teams is not that the big players are missing features. It's that every team wants something that is highly customized for them, and that leads to feature bloat.

Then people say, "Why doesn't Jira have ____?" In fact it does have that, but it's hard to find it in the massive UI that contains all those features.

I had this same issue testing Asana many years ago. I could tell that it could do what we wanted (or what anyone wanted), but I didn't want to spend 3 hours figuring out how to do it.
Try as hard as you like, you aren't going to find anyone to argue that C is as safe as Rust.

As for the TOCTTOU issue --- which is kind of silly, and had really nothing to do with Rust --- the diff to fix that problem is tiny:

https://gist.github.com/tqbf/4de61a3e34d2e4664044666c107abe7...

On a sane system, what's going to happen if calloc (or realloc, or strdup) returns NULL is the same as what's going to happen in the Rust program: the program will abort. Checking malloc returns is a bad idea, and causes more problems than it solves.

Similarly: this code does essentially the same thing with errors that the Rust one does: it swallows them and continues.

At any rate, while this C++ vs Rust discussion might be about language safety (I vote Rust, like any other software security person would), this subthread isn't.
I think you should wait 10+ hours to read different kind of comments on HN.

For example, if i open the comments about a “14 hours ago” post, I usually see a top comment about other comments (like yours).

I then feel so out of the loop because i don’t see the “commenters” your are referring too - so the thread that follows seem off topic to me.
There’s no real thing preventing #1 from being done in C++, but it is incredibly hard to remove bad patterns from a language that allows them. This is both problematic because these languages don’t provide first class support to remove unwanted features, and because huge amounts of existing code will use patterns you’re hoping to excise. In order to successfully do this you have to do a huge amount of both linting and dependency checking, and the resulting requirement that you not use any existing libraries makes using Result in C++ about as hard as doing a progressive rewrite into Rust.
Mm, just like we have wave-particle duality, one can also speak of some sort of “force-coordinate duality”, as it were. Just as we let the sine function be linear for small angles, quasiparticles with forces in Cartesian space are wonderful abstractions. Good physics – especially applied physics – is about handling this balance between precision and mathematical/computational simplicity. Mind, research physics can be the opposite; a lot of nuclear involves (often special) relativity as combined with QM. Until we have a unifird theory, however, the graviton and its force ain’t dead yet.
Speaking of reducing the dimensions of physical reality, a physics professor shared a very interesting video saying we should be thinking of photons and other massless objects as existing in 2d "areatime" as opposed to 3d "spacetime." I'm wondering if a revolution in simplifying the math behind physics is brewing.

I assumed "enormous attack surface" was referring to real systems, not toy examples. AFAIK, even C++ needs more than the std library to solve business problems in the domains I am familiar with. There are many ways to manage dependencies including vendoring in header-only libraries, where my point about the lack of tooling and clunky UX still stands.

I just want to use tools that help me get stuff done. C++ has had a 30-year head start, why can they not see the overall value-add of a default build and test tool and a format for package declaration and management.

All integer types have "checked_" arithmetic operations, which return None in case of overflow.

What happens to project planning when tasks and dependents form cycles? Doesn't that happen pretty often?
> beginning to suspect the developers aren't interested in moving it forward, or even properly maintaining it

This will be true of all systems. Devs hate adding comments, writing documentation, maintaining tasks/wikis/etc., and everything else that we need them to do. Some people try to make them track their time, which I think is both pointless and unlikely to happen.

The only solution to this is to move it out of the "discipline" column and into the "process" column. For example, I set up git hooks so that a commit will be rejected unless it's tagged with an issue number. And then I have another rule that says that issues aren't accepted unless they have the important fields filled out ("steps to reproduce" for a bug, "user story" for a feature).

It's not perfect, but it definitely creates better habits overall.
Rust has a higher floor set by the compiler, which still might not be up to your standards. That doesn’t mean that either C++ or Rust can’t have dependencies all over the quality spectrum, but it does mean that there are certain problems that Rust crates can’t have.
I actually very much would like the ability to do that.
Yeah ok. The moral to this story is “don’t fuck up”. Would be great if that was realistic.

There are very few stable orbits close to the lunar surface. Basically a couple of polar orbits with very specific parameters, and that's it.

The rest get so perturbed by gravitational anomalies that they fall out of orbit after a few months or years--faster than low Earth orbit where there is atmospheric drag!

> cranking out 3x as much music is unlikely to result in higher quality art

On the contrary, the more you produce, the more outstanding your hits.

Yes there's more crap too, but nobody sees the crap. They only see the good stuff (thanks to recommendation algorithms, charts, and marketing).

Here's the usual pottery class story that people use to talk about this phenomena:

> The ceramics teacher announced on opening day that he was dividing the class into two groups. All those on the left side of the studio, he said, would be graded solely on the quantity of work they produced, all those on the right solely on its quality. His procedure was simple: on the final day of class he would bring in his bathroom scales and weigh the work of the "quantity" group: fifty pound of pots rated an "A", forty pounds a "B", and so on. Those being graded on "quality", however, needed to produce only one pot - albeit a perfect one - to get an "A".

> Well, came grading time and a curious fact emerged: the works of highest quality were all produced by the group being graded for quantity. It seems that while the "quantity" group was busily churning out piles of work - and learning from their mistakes - the "quality" group had sat theorizing about perfection, and in the end had little more to show for their efforts than grandiose theories and a pile of dead clay.

You can also look at statistics. Across all fields, the people who produce the largest volume of work also have the most outstanding successes. Beatles, for example, credit their success to being forced to play strip clubs for 8+ hours every day for months. Created lots of practice.
The short answer is that Temporal is a fork of Cadence by the original founders of the project. The Temporal fork also has a VC backed company behind it. The Temporal is still an open-source project under MIT License. We believe the success of the open source project is essential for the success of the company, so we are putting significant resources into its development.

We spent almost year working on various improvements before declaring the first production release. The most important technical difference is that Temporal uses gRPC/Protobuf when Cadence is TChannel/Thrift. One implication is that TChannel did not support any security and Temporal supports mTLS. We are currently working on a comprehensive security story.

Here is a stackoverflow post that has more details about this: https://stackoverflow.com/questions/61157400/temporal-workfl....
