Well I did have the help of Silicon Valley’s most talented RF guy, who had met me and agreed to lend me his time and lab to help test my product. I never could have gotten this off the ground without him. Even if I got things working with my first layout, I’d never have been able to solve the manufacturing problem I had when the fab house swapped the RF crystal for 5 different clones.

I am forever indebted to Earl McCune for his help:

I did get a functional RF design that passed FCC testing, but the fear of regulations around RF sunk me. I read the specifications for wireless in the US, EU, Australia and New Zealand and designed a frequency hopping wireless protocol that I believe satisfied all three regions rules. The protocol supported operating in the 902-928 MHz band, 915-928 MHz band, and the 865-870 MHz band with pseudorandom channel schedules picked as a hash of the network name.

But damn it was a lot of work. And then I found out about how the FCC also issues directives that maybe count as law too, so it’s not just part 15 you have to comply to...

I suppose that could be called a lack of research. I saw it as naïveté and optimism, which might be the same thing. I learn everything else by doing so that was my plan for learning to run a business. I can’t research everything so I just dive in and see what happens. I was desperate to do something.

As far as the linear motors, they were specifically sex toys. The linear motors worked, but only at the prototype stage and they needed better electronics and software to work at the desired speed and smoothness the application would require. Here’s some videos I have not posted publicly, but have thought I should share (safe for work):

In a ahead-of-time compiled language probably not. The generic function is just a code generator for several functions that will get called in the right places, generated and put in the right places by the compiler, and then get optimised as per normal.

And no, being a dynamic language is not what makes Python slow. Lua, Nim and Scheme are all examples of dynamic languages with fast implementations.

The issues are intrinsically connected. People don't just start out e.g. going from nothing to building let's say a telecoms company. Entrepreneurship and creating businesses is a cycle of growth. For instance Bezos' first 'gig' followed a summer of work at McDonalds, which he hated. The next summer he setup a week long education camp for younger kids. He only got a dozen or so signups, but he probably made more from those signups than he did in last year's work at McDonalds. When you start making entrepreneurship difficult from the bottom up, you're going to end up with a really distorted picture of capitalism at the top since you're going to have some sort of strange bias in the companies represented.

And this is where I think corporatism excels. There are now just an immense number of rules and laws that are all increasingly esoteric even to operate quite simple businesses. And that's before you get into the countless fees and costs the government demands before you've even sold your first product. In other words when you kill off entrepreneurship and start moving away from capitalism, you invariably head towards corporatism which is itself headed much closer to feudalism than capitalism.

As for the king example, this was relating to the feudalism -> capitalism -> corporatism -> feudalism loop, not your specific suggestion. As for your suggestion, there are two big issues. The first is the same as discussed here. Capitalism and competition is a growth system. The reason e.g. Elon Musk was able to create a competitive rocket and vehicle company was because he earned hundreds of millions of dollars in another venture. No individual has any personal need for hundreds of millions of dollars, but it is strictly required if this individual wishes to engage in large scale ventures - the sort of which stand to massively improve society.

The second issue is probably the bigger point. We already have countless laws, on the order of thousands of pages, of laws relating to competition, anticompetitive behavior, restrictions on mergers and acquisitions, etc. These were all geared minimizing anti-competitive ownership. But the general rule in a corporatist society holds true. We have the FTC approve mergers between e.g. AT&T/Time Warner/Charter while rejecting mergers between far smaller companies that could eventually become the competitors for these sort of behemoths that increasingly stand above the law, and perhaps even above government.

In other words, write the laws and expect to see you and I only be able to own e.g. one tavern. But expect to see the king's friends somehow manage to own thousands. Corporatism in a nutshell.

If they are being successfully medicated they'll seem normal.

And even if unmedicated, they may seem entirely normal, because you're not watching them read the same page of a book 20 times, or doing other things where the condition causes a problem.

Not everyone with ADHD is like an energetic child who's had too much cake.
> All of these are also side-effects of over use of amphetamines...

Surely you are not the first person with this idea? Could it be that other people thought this too and compared unmedicated and medicated ADHD populations?

ADHD is heavily underdiagnosed in the adult population, hence it is not hard to find adults who have ADHD and who never took stimulants. IIRC, The studies show that kids medicated with stimulants actually have lower rates of substance abuse.
it's true that it's "just syntactic sugar", but in most languages it has call-site contracts that are either part of the signature (`await x()` to unpack the future/coroutine) or implicit (`x()` in an event loop host). and to change something deep in the stack means changing every call site everywhere.

that's a huge burden on a library (and thus the entire language ecosystem). it splits the world.

to avoid that, you basically need language-level support, so everything is awaitable... at which point you're at the same place as threads (but now they're green), where you cannot know if your callees change their behavior. which is both a blessing and a curse.

---

tl;dr yes but no. do you want your callee's parallelism to be invisible? you can't have both. (afaik. I'd love to see a counter-example if you know of one. there was one very-special-case language that made parallelism a thing you did to code rather than the code doing, but I can't find it at the moment. it only worked on image convolutions at the time.)
I'm a little skeptical, because hunting can be extremely boring.

> The specific story about the Baba reading Ram Dass' mind and informing him that he was thinking about his mother and that she had died of spleen failure stayed with me. Maybe he was informed the previous night that a Professor from the US was arriving whose mother died recently of spleen failure and the rest was about creating an illusion of omniscience?

I recommend learning about cold reading.

(A major component of it isn't just that it's quite easy to talk information out of you with vague prompts, it's that after the fact you will tend to remember that information as having originated with the cold reader. For instance, if the cold-reader just says "You are thinking about someone very close to you" and you say, "I was thinking about my mother", you will later remember the cold reader saying you were thinking about your mother.)
I've yet to see any mention of immutable data types, which I find I would use more than even generics.

You keep raising the straw man of "settled science" - who here, or in fact in the scientific community, believes this let alone proclaims it? Even in broader (non-scientifically literate) society, there are few people (in my experience) that believe science knows everything already.

Science had its "protestant" moment - it was called the Enlightenment, and it result from questioning the dogma of settled knowledge as promulgated by religions through the infallibility of scripture.

Whole countries? I have heard of only one - the infamous british pound. And that too it caused the GBP rates to fall but then financial damage to Britian as a country? What is your source exactly?
> it's my opinion that this is now a solved problem.

It's starting to look like a viable solution, but it's not even close to actually solved yet. Why does `go mod why <module` make changes to your module? How do you run go get to install a remote package when modules are enabled (without explicitly running `GO11MODULE=off go get`)? Why isn't the module cache concurrency safe? Why does the module cache sometimes mysteriously cause compile errors until you `go clean -modcache`? There are so many little bugs and oddities.

And as you mentioned, a lot of things have side effects now that didn't use to, which has catastrophically broken a lot of the tooling surrounding the language. Autocomplete using gocode used to be nearly instant. Now it sometimes triggers downloads and takes 30+ seconds.

I'm hopeful that go 1.12 will be the first release where this problem is really solved.
We don't have HN Gold to give, so please take an update instead.
It's important to both suspend disbelief to enjoy fiction from reality and take fiction with a big grain of salt that it's often missing considerations of reality. It's when people confuse and conflate fiction with reality minus critical thinking that hobgoblins of the mind get let loose to draw unrealistic conclusions.

Reality and fiction slightly intersect as a fuzzy Venn diagram, to a degree, but their more often echoes of imagination than of experience.
Seeing this on HN, almost thought it's no longer beta ;) (in the URL)
I'm not the expert on this, but I was curious so I looked into it a bit. I don't believe it required significant resources or crazy algorithms, but a clever selection of physics criteria to optimize. It was a ~20-dimensional Neumann boundary value problem [1], and a code named NESCOIL was used to figure out the shape of the coils that would produce the required magnetic field [2], which it did using Fourier series.

By the way, the unusual shapes of the coils can be understood intuitively from this picture: https://imgur.com/a/Bq3ABfQ. A plasma needs to be confined with a magnetic field in order to be heated to extreme temperatures, and a toroidal field (produced by the currents in the red coils) is unstable due to particle orbit drifts. You need to add a twist to the field for it to be stable (using the green coils). But if you unroll the surface of the torus, you can approximate the currents in both green and red coils using the discrete blue coils, and they're easier to build.

Your sister was on the wrong medication. I've never felt that way.
Furthermore, the New York Times and friends are competitors with Facebook, Google et al in the market for online advertising, so their interest in taking down Facebook comes across as self-serving.

For myself, I'd like to see a 95% contraction in the online advertising market $ value, so I'm uBlock Origin all the way.

Edit: for clarity, I'm not here to shill for Facebook - they're toxic! I'd be quite happy if Facebook shrunk to $0.
There's a difference between anti-Semitic attacks that are motivated out of antisemitism and attacks that are motivated out of self interest. I don't believe anybody thinks Zuckerberg and Sandberg implied anti-Semitic things about Soros out of their genuine hatred of Jews. Instead, the idea is that they tried to exploit antisemitism to obfuscate legitimate criticism of their company.

AWS Well-Architected Tool
I think we're talking past each other. I'm saying this:

A probability can only be assigned to an event. A distribution can only be assigned to the collection of all events. A probability cannot be an event except as a parameter into another part of a model.

Hence statements of the form "This is a picture of a cat with probability X with this credible interval" are category errors.

Notice how what you're talking about in this example is the parameter p not the probability that the coin turns up heads. Indeed to find the latter you must explicitly integrate over your p.

We agree on the analysis of confidence (although I'm not sure I'd say "I think the coin is fair with low confidence" after e.g. a single heads and a single tails; I'd probably say "I don't know, but that's the mode of my distribution").

My hand-wavy statement about updates alludes to the general case, where you can't necessarily describe your model easily with parameters, but instead have an arbitrary joint distribution. With parameters to your model you can talk about distributions and summary statistics about your parameters (e.g. p for Bernoulli), which is a special case of a general update function, but even if you don't have parameters for which to talk about, your update function still has all the information about "confidence" you need.

The downside of that (which can be provided by union types) is that `Maybe (Maybe X) == Maybe X` which may or may not be what you're after. The particular weakness is the interplay with generics where `forall t. Maybe t` depends upon the `Maybe` and the `t` not interacting. If you've got `forall t. t | null` then this type may secretly be the same as `t`---and if you handle nulls then it might conflate meanings unintentionally.

There are bugs, but I was referring to the design of the whole thing.

By the way, your "go get" bug was fixed today [1], if I understand your complaint correctly: With the new modules turned on, you could no longer do "go get" globally.

(I would agree that it's a little weird that "go get" outside a module installs it globally, while inside a module it installs it locally; that's going to trip up scripts and Dockerfiles, and it should really be two separate commands. "go mod add" to add a new dependency, for example.)

I live in a world where the best of intentions is often responsible for entitlement and cataclysmic policy decisions. This has shaped the mode of thought amongst myself and my peers to what we call: bottom line up front, which is a cruel form of honesty. I appreciate that not everybody can encounter such thought forming experiences, but you are correct. The nature of deferring towards sympathy is the hardest challenge people in my circumstance face in adjusting from one world to another when the adjustment is required.
I have kept in touch with many of my professors over 20 Y. On a whim I checked out their online reviews not too long ago and mostly agreed.

FBI Arrests AriseBank CEO Over $4M Crypto Fraud
I was born in September, so was usually younger than most of my grade peers. Did fine in K-6. Behavior was never an issue.

But I was diagnosed with ADHD in college.
To expand on this: for about two-three weeks after starting to take a Ritalin variant (this was in working life, I didn't have meds in HS + college for reasons) I was pretty on edge, getting pretty mad at stuff and even just pre-emptively cancelling meetings with some friends because I felt I would start yelling at the next person who talked to me.

I've heard this happen to other people too, and it's frustrating, but luckily it also comes with the feeling of clarity that was always missing, and fortunately people around me are supportive. No lasting damage, just "oh yeah I was a bit on edge then"

Scheme has an explicit minimalist philosophy, so much so that when R6RS was released with too many conveniences it fractured the language and community. Now there's two specs, R7RS-small and R7RS-big, and they're far less popular than R5RS.

Rationals are also the default number type.

Lists are the base type used throughout Scheme, and can be used to implement arrays and hashmaps and whatnot, so Scheme doesn't really need them, you can just use a library.

... That didn't stop the committee adding types to the spec. Like records, promises and other complex types.

What is useful and necessary to a language isn't defined by what the processor can natively do, or we'd only use registers, not arrays. And it isn't defined by a overbearing attitude towards one or more philosophies.
If I were doing this today, I would prototype the problem in Python and after realising the startup penalty, would rewrite it in D's Mir [1] or Nim's ArrayMancer [2].

> Simple scripts, bash until they need their first 'if' or flag or loop, then Go too.

If you don't mind, can you give a little insight on what this looks like in practice? I'm not sure how to use a compiled language as a script. I've played with executing go as a script using a shebang hack, but I somehow don't think this is how others are doing it.

For reference, the shebang hack I was using looked like this:

//usr/bin/env go run $0 $@; exit $?
package main

import "fmt"

func main() {
fmt.Println("i am a script")
