Lighntning, also known as not-Bitcoin. Lightning does away with Bitcoin's guarantees, unless you close the channel after each transaction, at which point it costs more than sending BTC directly. And something like CashApp is even worse

Computational irreducibility is one consequence of the halting problem being undecidable. If the halting problem were decidable, there couldn't be any computationally irreducible algorithms.
933.
by simiones 3y ago
Well, it depends how you take it. The fact that the halting problem is undecidable tells us that there is no algorithm to tell if an algorithm will ever halt for some input. This implies that the best we can do if we want to find out if a

Someone else gave a very good definition, but I'll add that historically, the Lambda Calculus was a system designed by Alonzo Church to get a formal notion of what "computation" means in mathematics. As in, a formally-defined

Reading through their docs, it seems cert-manager should support this, but unfortunately it wasn't available in our cluster. I'll see if there is any reason we couldn't add it.

Unfortunately this would probably not work for my purposes - the issue on my side is that I want to enable MinIO to use server-side encryption; however, MinIO doesn't support SSE unless TLS is enabled inside MinIO itself - so it's

One thing I just hit is that there doesn't seem to be any way to ask from a Pod to get a TLS certificate signed by the cluster itself (that would only be valid inside the cluster, of course) that is valid for the IP(s) and DNS names as

As far as I understand it, the ether was supposed to be matter, ultimately made out of some kind of particles that obey laws of motion. Conversely, the electric field is just a potential. It's not made up of anything, it just describes

> In my opinion it’s easier to keep GR As far as I've read, most physicists have the opposite impression: that QM is much closer to the truth, and that it's almost impossible to add explain the Heisenberg Uncertainty Principle

Given that most major (in terms of usage) open source products are little more than commercial collaboration between large corporations (e.g. the Linux kernel, clang, Kubernetes, the various Python ML libraries) I'd say that much of th

Principia was proven right at every turn, and explained all of the observed mechanics experiments, all the way up until Maxwell's equations were formalized and their effects tested out, some 200 years after it was published. It's

The problem is that scale is completely smooth. IF there were some strict scale at which each theory applies, as I said, you'd then have problems for phenomena that straddle that scope. You can always add an extra electron or atom to a

Sure, but once it keeps failing for a few decades, and given that ST is significantly more complex than either QM or GR, not simpler, there has to come a time where it simply is abandoned, even if it hasn't been disproven.

No no; I'm saying that if you apply QM as it exists today to describe the motion of light beams around the sun, you will not get any effect similar to gravitational lensing. Since gravitational lensing is a real effect that we have cle

Some other notes from what I understand of current mainstream physics: - elementary particles have no defined size in QM (electrons, quarks, neutrinos, photons etc); there is no known lower-bound on how small they could be, and there are se

Well, I don't think any physicist believes that an actual singularity exists in the center of a black hole in physical reality. The mathematics of GR actually do predict a singularity, but this is typically viewed as a limitation of th

That's a very good point. In particular, "complete" refers to the ability of the mathematical-logical system to prove every statement that is true within that system, in terms of the system. This property is completely irrele

The problem with this line of thinking comes from the way the problem is posed. The reality is worse for both GR and QM. QM is not a theory about small particles: it is a theory that describes the evolution of any object whatsoever. It just

That's my point: what experiments could be performed have been performed, and have failed. Also, it is a massive weakness of the theory that it can be used to predict such varied values. This is a big part of why it is not exactly a

While I understand these are just idle musings, you should note that this is failing to address the biggest problems that actually "require" a theory of everything. Most importantly, it doesn't explain how quantum fields inte

I think there are all sorts of other potential tests of string theory. The problem is that for all the actual tests that were ever proposed, it failed (supersymmetry, various proposals for sizes of the extra dimensions).

I would note that at least browsers are multi-platform. This seems to be aimed more at making it harder to browse the web on certain devices, regardless of the software you run on them. I would also say that JS is not the (only) problem mak

So this is even more insiduos, and an interesting way for Apple, Google, and MS to pay Cloudflare to use its dominating market position to help safeguard them from other incumbents: you either work to get your devices approved in this schem
