As there doesn't seem to be a consensus on whether relativistic Turing machines can actually exist, I'm not sure this constitutes a proof (though the paper itself is beyond me).

The idea of relativistic Turing machines is fascinating, however: "... we might [through clever application of General Relativity, likely involving black holes] be able to speed up the time of one observer, say C (for "computer"), relatively to the other observer, say P (for "programmer". Thus P may observe C computing very fast ..." [0]

But (from another source) "... all these claims rely on the provision of one or more unphysical resources ..." [1]

Well, that may be obvious to you, but it’s not obvious to me, and (here’s the kicker), neither of us can know for sure. Only very few specific people at Google are in a position to absolutely know whether this is happening, and they can’t tell anyone.
What would happen if the OS gradually forgot all changes that were made since factory settings, and all files that mattered were stored somewhere else? Would it only be annoying, or would it be comfortable to know that the system would gradually be heading toward the initial "clean" state? :D

As for the track record, there's also Apartheid and the appeasement of Hitler, so even if that wasn't utterly besides the point, I'm not convinced of your claim without any examples of it, since I couldn't come up with any myself.

Could you list some of those aviation channels?
Many years ago, an unpleasant family member owed me money and I had tried in vain to get it back, until someone pointed out that the cost to rid myself of the negative experience and person was to view the amount owed as a sunk cost and to walk away. From the moment I saw it this way, I felt relieved and happier.

I know a funded startup is much larger in scope but perhaps the cost of your sanity and well-being is walking away (as user random_comment says at the end: "You can be free of that particular burden any time you choose to be.").

> OpenStax at Rice University is a 501(c)(3) nonprofit charity

Good to see that OpenStax is a 501(c)(3) charity, which is the nonprofit classification where donations are tax-deductible and thus restricted. That makes it harder for the organization to be influenced too directly by sponsors, since donations cannot be used for purposes which would yield direct marketplace advantage.

I also see that they use a permissive, attribution-based license for their publications. That makes it easier for businesses to consume those materials and also to contribute.

https://openstax.org/license

The combination of 501(c)(3) and business-friendly licensing reminds me of the Apache Software Foundation. The more orgs using that formula, the better!

Plenty of the small PT6s coming off older airframes for -135 upgrades or airframe retirements.

That's a good point, but I don't think drawing the line is so easy. Take copyright and dmca. In the USA you can argue that the "copyright lobby" is effectively one of the rulers in power -- they write and enforce laws, after all, one of which is the DMCA and used for censorship. And it is absolutely meant to keep themselves in (economic) power. It also establishes a precedent for censorship more generally, a slope that can be made slipperier over time.
“HiFive Unleashed is the ultimate RISC-V developer board.”

A development board is light years away from a 19” rack mountable server with out-of-band management (lights out management) and everything else that goes into such a design.

I for one am not content to just tinker with toys; I want servers so I can get some real work done.

> We need to out together a cohesive document that explains why modern computing needs a serious overhaul, and a plan to get there. The computer should be fast; UI should be appealing, but minimal. It should be understandable and open down to RTL of the processor. The core should be aggressively minimal, and fully understandable. Networks with no central auth should be at least an option (preferably a local mesh). It should be cheap.

Agree on all those goals. Over the years, I've seen some essays and comments scattered all over the web containing those ideas; it would be great to collate all of those thoughts somewhere.

What I find a bit strange is that outside of Kitten (and Cat before it) nobody seems to have tried to make any stack-based languages with a strong typing system that prevents this. I mean, shouldn't it be trivial to follow which type of data a word expects from a stack, and which type it returns? The only limitation I can think of is words that leave a variable amount of data on the stack (one workaround would be to forbid that, or to have the type system be able to express that as well).

I suspect something like Julia's type system, with Bits types and Abstract types, would work perfectly here[0][1].

Thanks, yeah, that's what I was wondering -- it doesn't compare them very much though.

The main complaint against differential privacy is that it's a very restrictive definition. However, at least in theory, it seems to often turn out that if an algorithm releases enough information to violate differential privacy, then it has released almost enough info to blatantly violate any privacy definition.

So the key question for any other privacy notion is to show circumstances where it can be satisfied easily, but DP can't (or DP incurs a much heavier accuracy loss).

They're becoming less common, but mechanical automobile (and bicycle) odometers are little mechanical computers of a sort. Baseball and softball umpires (especially for rec leagues, not sure about professional games) often use a "clicker" (https://www.amazon.com/Easton-Umpire-Indicator/dp/B07BYX8XQL for example) to keep count of balls and strikes.
It's not in use today but if you haven't already seen it, I bet you would enjoy Bill Hammack's series explaining how a 100 year old mechanical harmonic analyzer works.

EDIT: Tracing deals with annotating methods, and how long they take. E.g. function a took 3 seconds, and make 2 DB calls that took 1.4 seconds. Metrics deal with how many times you made calls, how long they took, etc. So two importantly related parts of application monitoring.

Metrics is different to Tracing in this case. From the surface (or from someone who doesn't closely follow), OpenCensus contains metrics and tracing (and maybe more).

OpenMetrics appears to be the standardising the metrics part, hence the sentence that OpenMetrics is being integrated with OpenCensus.

Now, you might ask, because I've also asked: what are the pros/cons of Census over Tracing for tracing purposes?

It does look like both standards compete and perhaps diverge. I once sensed a bit of bashing of the latter in the OpenCensus Gitter channel; which convinced me to just stay with OpenTracing as they already had more integrations at the time.

At least Metrics is being promoted by the same interests as those working on Census, so we won't see another set of standards targeting the same applications (LightStep, StackDriver, etc).

In short, why can't OC and OT combine their efforts?

There is a vast array of mathematical results that hold _if_ Riemann is true. Wikipedia has a list:

https://en.wikipedia.org/wiki/Riemann_hypothesis#Consequence...

Essentially, it seems to encode a hard ground truth on the behaviour (and in particular the growth) of arithmetic structures. It often (but not always) is the case that Riemann gives you a best/strongest version of a result. Meaning that the zeta function in some meaningful way encodes all there is to know.

Well, actually that's what I'm mainly interested in - what the technical differences between OpenTracing and the tracing part of OpenCensus are.

Excuse me for my badly worded question.

However, why they can't combine their efforts:

Probably a lot of infrastructure is built on both of them, having the aforementioned potential technical differences, which could make any unification backwards incompatible, as in: traces produced by the unified standard wouldn't be parsable by todays infrastructure tooling of the companies using them.

There may also be different tradeoffs chosen, which again boils down to the question regarding the technical differences.

A Thunderbolt controller contains a Converged I/O switch (CIO) plus a PCIe switch. The Downstream Ports on the PCIe switch are attached to the CIO switch and represent so-called PCIe adapters which encapsulate PCIe datagrams into Thunderbolt datagrams.

The PCIe throughput is thus the minimum of the CIO switch's capacity, the PCIe switch's capacity and the PCIe adapter's capacity. The PCIe 4 lane interface is only how the Upstream Port on the PCIe switch is attached to the CPU or PCH.

It is very unlikely that Intel will answer this question satisfactorily because they'd reveal details of the controller's internal architecture.

Note that a PCIe tunnel may pass through a Thunderbolt controller without being terminated on it. The CIO switch must then handle that tunnel's traffic in addition to any tunnels terminated on it.

(Disclosure, I've authored a couple of commits in the Linux kernel's Thunderbolt driver.)
