Am I the only person who struggles with the idea of anything that's set at 1-to-1 with a single fiat currency being called 'stable'?

Certainly, USD is more stable than BTC or ETH, so a "stablecoin" pegged to it will share that increased stability. But that's more a question of prevailing economic conditions than anything, and there's nothing stopping a fiat-based coin from sharing in the inflation, deflation, or collapse of the pegged currency. Even if we assume the implementation of the currency perfect, you're just changing the set of things your currency is vulnerable to.

I wonder if anybody's working on a Stablecoin which tries to mitigate this using something like precious metals, or a pool of fiat currencies (with the understanding that something hitting USD hard might not hit CNY or EUR or GBP as hard, mediating the effect).
Also what about the data race detection stuff that rust does? A GC does not stop data races.
The article makes it sound like the autopilot was engaged, the plane slammed into a dive, and the pilots panicked for 18 seconds before finding and fixing the problem. It looks like what actually happened is the plane started to slowly pitch down; the pilots were busy with the after-takeoff checklist and didn't notice for 15 seconds until an alarm went off, when the pilot immediately disengaged the autopilot, pulled up, and reduced engine power.
> It seems there is exactly one reliable way to make this assessment. Look at where people move to.

Not necessarily. Many cities strictly limit how much housing they have, such that there is a hard limit on the number of people who could feasibly live there. SF is a good example of this, since it's also small and geographically constrained. Saying "well, the net increase in people was small, so therefore it must be that not so many people want to live there" is not necessarily true if physically the city cannot accommodate many more people due to regulations.

Looking at where people move to is useful, yes, but high housing prices are themselves often a marker of desirability, particularly in supply-constrained markets.
What we don't know, is how it would have worked out if we didn't have C.

There is also a bit that most of the bad security failures are not as sophisticated as the ones we mostly talk about. (Ironically, of course, the widest vulnerability lately was at the CPU level...)
If you invest well in education, create quality human resources, and then give them resources they can do anything.

In fact its mostly small countries who do big things. Greece under Alexander the great.

And more recently England. It was like a small Island and pretty much ruled the whole world.
> and you’ll see that SEXPRs are right there lurking barely beneath the surface

Then why the surface? Why can't we just have a lisp with a good data-science library? Scheme seems the easiest of all the programming languages to me. I bet I can teach Scheme (not including advanced FP stuff though) to anybody faster than any other language although I have never used it to code anything serious (because libraries), I actually find it simpler than Python or even VBA. Phenomenally everybody seems so scared by the parentheses but these are not a serious problem given an intelligent IDE with proper outlining and highlighting.

That's a question the lawyers are negotiating right now, but if we needed to "ask for a transactional history of the funds" our business model would be untenable.

We're getting into territory I'm not allowed to talk about now, but note that all the crypto-currency exchanges are operating under a similar "keyhole" principle, of only doing KYC at the withdrawal or deposit steps.

>Basically, is it actually going to be realistic to exercise the cash-out functionality, or is it going to be a theoretical thing that end users in the cryptocurrency space don't actually use?

If should be a realistic thing, where we have real regulations applied to us and real banking partners that aren't going to suddenly pull their support, and who know exactly what it is that we're doing.

Canada is a bit of a different market though.
It does and did. They set the correct altitude. They put the autopilot in the wrong mode.
You mean to get either 0-9 or 'no number'? Here are two approaches:

1) Integrated. Represent 'no number' as class number 11 in the original model. Retrain it with this additional class (needs additional training data).

2) Cascading. Train a dedicated model for 'number' versus 'no number' (binary classifier), and use that in front of the original model.

Note that the MNIST data comes already extracted from original image, centered in fixed-size images of 28x28 pixels. In a practical ML application these steps would also need to be done before classification can be performed.

Many things are "sandboxed by design." Few things are true sandboxes.

I'm very skeptical of the idea of throwing out virtual memory and process isolation to depend instead only on software sandboxes.
This is why crypto is so attractive to libertarians.

It requires getting something for absolutely no effort and conflates economic growth with semantic labeling of abstract pseudo academia aimed at the very people whom they are trying to steal money from.

Somebody needs to put together a "Wall of Shame". History will teach us as this period as a "Dark Period" where financial scammers flourished with the help of Russia to launder the very money they took from their people.

“Eventually, someone will invent the future...”

You’re doing that thing where you ask what exists that’s better.

Not _quite_, although it's a fairly pedantic technical distinction.

As I understand it, an organism that reproduces sexually (rather than asexually) has a sex dependent on the gamete it produces. There _might_ be some insects with more than two sexes[1], but generally a dioecious (two-sexed) species will be anisogamous, meaning one sex is responsible for bringing a load of smaller, simpler gametes (sperm, pollen) to the party whilst the other brings a single, larger one (egg, ova). Put them together and babies happen.

The mechanism that determines the organism's sex varies by species. Homo sapiens are a species that have an XY sex-differentiation system. As a sexually dimorhic species (our two sexes look different), one's chromosomes also cause one to express distinct secondary sexual characteristics (e.g., male facial hair, female breasts). Man boobs and bearded women exist, however, so these characteristics are not a 100% accurate indication of one's sex.

Also, as another reply stated, the meaning of ‘gender’ may or may not == that of ‘sex’.

Gender referred only to a linguistic concept or was a synonym for sex until the '60s-'70s, when radical feminists and sexologists like John Money[2] proposed that gender be used to refer to the expectations, roles and responsibilities that a culture assigns based on sex (i.e., women should raise kids, men are more aggressive). Personally, I feel a term like ‘tertiary’ or ‘socio-sexual characteristics’ would have been a better, less confusing choice, but unfortunately I wasn't around in the '60s to tell them.

Outside of social sciences, the words generally remain synonymous. Within social sciences the '60s-'70s-era distinction is retained and gender is studied almost exclusively (as you might expect of a sociological concept rather than a biological one).

The article seems to say FPGA on a high latency bus can only accelerate workload that are streamed via DMA, and implies that a general purpose accelerator has to be closer to the CPU. Sounds like a coprocessor, like putting an FPGA into the slot where the 8087 used to be.

That made me think, why not get even closer? Why not have an FPGA as execution unit? Modern CPUs have multiple ALUs, multiple FPUs, multiple vector units. Wouldn't it be great if an FPGA was added to that, such that the instruction set becomes extensible?

The idea is too obvious to assume nobody ever thought of it. Why isn't it done?

> From a point of view of postmodern c++, rust has little to no advantages left.

My entire adult life I've been writing C, I resisted Rust for a while but took the plunge when a C++ project came along that was in dire need of being reworked. I liked it, the language and the compiler and tooling around it helped me tremendously.

I assume you're aware of all the things that Rust statically guarantees for you, and I'll also assume you know the difference between language complexity and language implementation complexity (eg, the compiler or some other tooling):

I've been skimming through the C++ section of cppreference.com, and oh boy, there's heaps and heaps of... stuff... just stuff. The interplay between all that stuff is complex and it's hard to keep everything in mind. Keeping things in mind is important for correctness, or at least for having a reasonable amount of confidence in what you're writing. Information locality is also important for correctness, and C++ lacks both of those. I'll even go further and say that C++ is a write-only language, like a garbage bin of features and exceptions to each of those features. Rust has many many many clear advantages (and some disadvantages) compared to postmodern C++.

>That essay is a significant source of belief in the myth of inherent mathematical truth, but it has flaws and is far from proof.

I don't know where this characterization of "proof" comes from. It is merely an essay, and not intended as anything other than one. When I read it years ago, I did not get the sense that Wigner was asserting inherent mathematical truth.

>It focuses on cherry-picked phenomena that are easily represented by simple math, but ignores those where math struggles or appears to be inherently incapable.

Does he assert anywhere that any phenomenon will yield easily to mathematics? I don't think so. I think his point is that there's no good reason that even the phenomena that are well explained by mathematics should yield so easily to it. It's not "All of nature is surprisingly mathematical." It's "I see no good reason that a lot of phenomena is mathematical."

I'm too lazy to reread the essay, so I may be remembering it wrong.

This sounds more like a motivation than like a trouble.
Nim is a lovely language but I disagree with most of your points.

* The Rust borrow checker prevents a lot of issues in C(++) code. Including thread safety. Nim does not provide anything new in this regard.

* The lack of a GC is a feature, not a detriment. One of the reasons why Rust applications are often very fast is because the language naturally guides you to avoid allocations when possible and allows low level control where necessary. Combined with the safety guarantees of the borrow checker, this is a powerful combination. This is possible in Nim but using GC is easier and will be the preferred solution when in doubt.

* While Mozilla support does help a lot for sure, a lot of the hype around Rust (imo) comes from people trying it out, just falling in love with and then promoting it

...Which is why wget was not used. If curl had been GPLed, the car companies would have used some other tool, or made their own.

One example, the leader of a state shouldn’t be doing anything since this biases their judgment, instead they should always rely on their ministers to be experts, and the fewer decisions one makes the more ideal the leader. It’s not just simple delegation that they’re talking about, it’s that at least on person has to have a clear view of the whole picture to make subtle adjustments, and if the leader is wrapped up in doing the work himself then it’s no longer possible. They have very strong words for leaders who do work themselves as being unfit and bluntly stupid. It certainly resonated for me as being completely correct, and adjusted my management style.

Typically/historically, autopilot systems have very few checks and controls, mainly because pilots insist that they know better.

Having worked with several autopilots in sims, they are extraordinarily user UNfriendly and unnecessarily complicated.

But, aviation is extremely conservative (and rightly so) and as such, changes and improvements are very small and incremental.

Altitude is above sea level, and there are airports and areas below sea level. This in and of itself causes all sorts of problems from time to time whenever a programmer forgets this and encodes altitude as an unsigned.
Good news: for cryptographic protocols and methods they are! Many of the cryptographic primitives that I implemented for my test TLS 1.3 implementation (https://github.com/syncsynchalt/tincan-tls) come with test vectors in the spec itself, and the rest always had test vectors supplied in a separate doc.

For an example see Appendix C of the AES standard, FIPS-197: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.197.pdf

In the case of TLS 1.3 I was able to use this IETF draft: https://tools.ietf.org/html/draft-ietf-tls-tls13-vectors-07
I have a customer that loves to hear my 1996 model M. To her, it means that progress on work is getting done to resolve the issue she called me about.
I think, its different because its dimension where usefulness of data goes does as the data ages. TimescaleDB for example, does optimisations ( they call it chunks or something) based on this fact.
Or it could be some other (conventionally inherited) trait that you and your father share.
Yes. Most approaches start from 2000-4000ft.
Sure, if you're coming in for a landing, you will dial your autopilot down as you are granted clearance. Ultimately you will switch to approach mode which ignores the set altitude and instead follows the radio signals down to the ground.
Your greatly overstating Tesla's advantages. EV drivetrains aren't quite drop in replacements but they are close enough that the first modern commercial EVs... including Tesla...were simply converted ICE vehicles.

Also, Tesla doesn't make batteries, Panasonic does. Tesla just assembles them. Panasonic also sells batteries to Tesla's competition. And based on Tesla's past issues with paying vendors, if they miss even a single payment to Panasonic their supply advantage could disappear immediately.
I tried using Mnemosyne (a Linux program that uses the same algorithm) years ago when I was in school, and did not find it effective. It was a pain to enter the cards, and a lot of my material was mathematical. Also, you needed to be really consistent. Take 2 weeks off and the algorithm behaved poorly.

Looking back, I think the problem was the lack of documentation on what to expect. There are always questions of how many cards should you do in one session, and how you should rate them.

A few days ago I started again, this time using org-drill. As with everything org-mode related, the experience is much better this time round. When it presents you a card, it has all the LaTeX rendered, and all images showing. Let's see if I don't get sick of it this time round.

I've been driving LEDs from my .vimrc - that's a trick the M couldn't do.

Of course, there are also suburbs of major metros. Lots of people commute into Manhattan from Westchester every day. And, traditionally, most of the tech jobs in "Boston" were actually out in fairly far-flung suburbs and many still are (with the notable exception exception of biotech in Cambridge and the satellite offices of SV firms).

But you're absolutely right that a lot of new college grads want to live in the city and maybe not even buy a car.

The majority of the established workers already own houses in the suburbs, exurban areas, and even NH. For many of them, a location that's actually in the city is a bug, not a feature.

Nope, not really.

1. They are choosing and then providing devices. This is very important because it means they have physical contact with the device, initially, so they have means to bootstrap cryptographic system by way of injecting keys, etc.

2. They are middlemen transferring messages between multiple parties that use their devices without having to understand the secret part of the message and only routing the messages.

3. They are paid well enough for the service that they should be able to cover expensive devices and processes like manual key injection or expensive hardware security modules.

4. The core of the business is security, if it is not provided nothing else will change the fact they have not provided what they were paid for.
