Newton-Rapheson method to calculate X = 1/D

1) Make a guess at the reciprocal X(0) (this can come from a small LUT, but a static "guess" can also work)

2) Calculate an improved reciprocal X(n) iteratively using the relation:

X(i+1) = X(i)*(2-X(i)*D)

Repeat (2) until X(i) is accurate "enough". This is relatively fast, since the # of correct bits in X() doubles for each iteration.

There are several other methods:

I don't know, but so far under his lead, Apple managed very well selling the new products they bring to the market.
That is a really absurd statement. If you can't vote, you can also not run for public office. The way you enact change in a representative democracy is to organise, create a party and then get elected, or to join an existing party and rise in the ranks. Some parties in Germany have a 50:50 male / female leadership split. I personally know several women that were active at the local level and ran for public office. A female acquaintance of my parents was state education secretary in the 90s for a while. None of that was possible in Switzerland on the federal level before ~1970.
Tesla didn't invent batteries. They didn't invent electric motors. They didn't invent pretty much anything novel.

They execute superbly, had a brilliant strategy of starting as a luxury vehicle to be the beachhead for getting an economy of scale, and were risk takers, but lets not pretend they invented the market. They didn't.

No doubt they have loads of superficial patents though, but Tesla has an open patent policy and a declaration that they won't sue, so that doesn't seem to matter much.

Apple can buy a company like Magna Int with pocket change. Recall that Magna made the "Sony" electric car, bumper to bumper (Sony put in some screens demonstrating a Sony-esque UI), because that's what Magna does -- they're the maker behind a lot of automobiles, either in part or whole. And Magna has loads of patents around the engineering of vehicles because they've been doing it for decades.

I think you’re both right. If you frame the original comment as “don’t write final production code without thorough modeling” it works both ways. If you want to counter with “well our non-final code always goes to production anyway!” You have a cultural problem that needs addressing.

No, I read it, and regretted reading it, and figured I should save others the trouble. I specifically called it out as baity because it claims not to be, which is ludicrous, because it's a meandering piece that isn't really saying much ("try boneheaded solutions") of anything, seems like a mix of generalities, caveats, and self-promotion.

I'd challenge you to ask yourself this -- Is there even the slightest chance that anybody who reads this article is going to become 10x as productive from this "technique"?

If not, then that seems the definition of linkbait.

How to Start and Grow a Test Case Management Tool (USD 12K MRR)
Oh I see, misunderstood you there. Yeah, many apps are basically just the desktop version with some pre-configured scaling to make them barely usable - but as far as I know it is only by necessity until the mobile friendlier alternative emerges.
But while it is good to see the advances mobile linux GUIs make, they are still far from usable as a primary device :/
This post starts with the implicit assumption that the normal structure for a meetup is a talk. Is it?

I don't go to many meetups, but by far the best are the ones structured for peer discussion, not lecturing. Extreme Tuesday Club has been doing this for decades:

How common is it to have structures like that? Have i just been lucky?

The specific office hours format is different to either of these, but it's a similar flavour. I'd like to try it (which means i should propose it for XTC).
They can, but then their company doesn't grow. Why would you do that?

Otherwise it has some nice features, comparable to some of my other cards but more tightly integrated with the phone.

That’s contactless payment. Entirely possible without any Apple anything.

A more cynical person might say that one of Apple’s strengths is marketing commoditised capabilities as something special.
That is a good point. I run couple of subreddits/fb-groups and it always felt a bit off that I couldn't monetize my community the same way I could when forums were distributed. However, these platforms monetize my communities for themselves.

I had to read this a few times to understand what your product is, maybe because I wanted to stop reading halfway through the first sentence. Most people scan and if the first scan is too hard they move on.

I think the first sentence should have shorter, simpler words.

Maybe: “Build an online community in two clicks with DiscoFlip. Easier to configure and monetize than Reddit or Facebook Groups.”
With mirrorless, you can put the back of the lens closer to the sensor (don't need to flip a mirror out of the way at high speed) which reduces the glass needed for the same effective focal length. Less length = less glass. Less glass = less mass, which means less force required for an electric autofocus motor to push around all that glass.

Modern zoom lenses have anywhere from 11 to 30 elements, in 3-11 groups, that move at different speeds relative to each other. Doing that with a tiny electric motor, precisely, for a decade is a tough task, especially when the mass of the glass starts to exceed 1kg.

With a mirrorless camera, you can reduce the mass of the lens by ~10% for a full frame camera. With an APS-C sensor, mirrorless, you can reduce the mass by 33%. With a "micro four-thirds" sensor, the mass of the lens is less than 50% of a full frame. Rough numbers. As with everything, there are pros and cons to going with smaller sensors than full frame.

That's a polite interpretation. I assume the real reason is they wanted to create a walled garden. Seems like the EU, at least, forced their hand on that one.
Yes, that was the point I was making. It seems that it flew over peoples heads.

Being on the spectrum without learning how to work around neurotypicals is the issue, the same way that being 7 foot tall without the physical modifications needed to support that body is also an issue.

I am very much on the spectrum but have developed a large number of coping strategies [0]. Had I been diagnosed and treated as a child I would have never had the ability to become anywhere near as successful and fulfilled as I am today. Instead I would have been drugged into being an office drone and probably been looking at suicide about now.

[0] One of the odder ones that no one neurotypical understands is an algebra of social relations I use to model office politics. It lets me evaluate the social graph analytically several jumps further than any person can keep in their head.

Government killed public transit by mandating that bus and rail had to be separate entities. As rail travel plummeted bus routes were trying to increase rail traffic with bus routes serving rail stations.
Lockdown had a variety of goals but the current situation can generally be classed as a policy failure. Hospital collapse is the worst case scenario but isn’t the only goal. Other important goals include:

* keeping schools open (mostly a success)

* avoiding economic disruption (mixed, tending towards failure)

* avoiding unnecessary deaths and long run health issues (failure)

* Avoiding a second lockdown and the related uncertainty and stress (failure)

* returning to normal life (failure)

* avoiding dangerous mutations (failure)

The UK is an island and could have fairly easily done a NZ/Australia strategy over the summer when seasonality made elimination easy. Jurisdictions that made that choice are doing better on all front.

I live in one such jurisdiction (atlantic canada) and we’ve spent less time in lockdown, had a good economy, and mostly avoided deaths and hospitalizations. Seems a clear winner.

Perhaps a country in the middle of europe couldn’t have done it but the Uk certainly could have.

And no, this pretty clearly shows govts had no long run or even medium run strategy. Europe will be in rolling lockdowns till april or so, because of a premature declaration of victory in the summer.
Ehhhh. Self driving cars have been just around the corner for a long time now. Not saying it won’t happen, but I wouldn’t buy a Tesla today on the assumption that it’ll happen within the lifetime of that car.
When AMP first came out in 2015, I had a mobile internet plan with some pretty extreme data caps with throttling down to LTE after they were exceeded. I absolutely loved AMP. I imagine I was in the target audience.
The Tesla Model S is not an ideal example here. It’s a great car, but also Tesla’s first mass produced model. It’s over-engineered in many ways and has way more parts and complexity than if Tesla were designing the same car today!

Comparing the Model S to the Model 3, and now the Model Y, we see with each generation simpler designs, reduced part counts, and easier assembly which all translates into improved reliability and, often, repairability.

Sandy Munro’s Tesla tear downs are a great reference for this stuff.

This nugget stood out for me: "In my experience most codebases have a pure functional subset, and I believe writing that subset in a pure-functional style is nearly always a win for the long-term health of the project."

This is probably often true. In high level applications, the idea of classing or abstracting out your i/o from the core functionality is appealing from a security and reasoning perspective, but not sure if serious developers think that way.

Would you need to understand the rationale behind the codebase from a functional perspective, and even the economics of the business logic behind the features? It's kind of an architects view of "this thing essentially reduces to a queue and if I optimize for this, I get more value."
Requires Consideration
There was never a "freedom to post" on social media, so you haven't lost that. The idea of "freedom of speech" was formed during a period of time when there were natural barriers to speech such that bat shit crazy qanon conspiracy theories and other such nonsense couldn't propagate widely. Nobody ever intended "freedom of speech" to equal a right to use a frictionless machine to propagate lies to billions.

Prior to the internet you could for the most part visually distinguish between the crazy and the legitimate - the crazy was in crayon on cardboard scraps, full of misspellings. The higher quality crazy was type written on a misaligned sheet of paper, thick with whiteout, still full of misspellings. The legit was professionally edited and published. Not 100% of the time, but a good fraction of the time.

Now we have spell checkers and grammar checkers and blog services like medium that make everything look really really good. That visual heuristic is gone. We need a way to invert our current equilibrium of "it is easy to get bad information out, and hard to get good information out" at least back to how it was: "it is hard to get good information out, but it is even harder to get really bad information out." That isn't censorship.

As for democracy in the US, as a US citizen I can tell you it is on the ropes, mostly due to social media, but it is better off today than it was four years ago just because people are at least starting to think about how to get social media under control.

Every freedom my parents, grandparents, and great grandparents had I have, and more. I'm hard pressed to identify a single one that is under attack.
this post seems like a graphically appealing way of just making the usual "FP is better" argument, except without any other actual argument other than "In my experience most codebases have a pure functional subset, and I believe writing that subset in a pure-functional style is nearly always a win for the long-term health of the project."

in my experience I've seen codebases that are entirely object oriented where we are writing methods, not functions, or codebases that use methods or functions as appropriate, and they also have done just fine long term.

How is this article making any real argument for the former and not the latter?
I thought he was saying the `end` in range begin/end was now allowed to be some empty signifier to tell things to look for the null pointer (null is a sentinel, but `end` itself is now empty). That may not be right, I don't know enough about the new concepts stuff and range seems to be part of that.

edit: looking at this it maybe covers it:

There are reasons to do this also, as the number of shareholders can trigger reporting requirements even if you are private (jurisdiction dependent, of course).

In my opinion selling within the existing pool shouldn't be restricted, but this could become a sticky issue around board control so that probably contributes to the desire to control/curtail it.
The research study behind the book is about autistic traits and not necessarily clinically diagnosed autism.

Yes it is a spectrum and yes you can be "high functioning" and have "milder symptoms" but it is way more than that.

Autism has a wide range of clinical subtypes and there are extremely debilitating ones.

At its worst, you have kids who are non-verbal and can't communicate. If they don't get therapy they can be become aggressive and violent as they get older. A screaming hitting 5 year old is far different than a screaming hitting 15 year old.

Spinning in circles, flapping, repetition, sensory issues, the requirement of definite routines. It's a whole different world and exhausting.

You can identify signs of autism as early as 18 months. At age 2 or 3 it can be reliably diagnosed. I've personally seen autistic non-verable young kids go through intensive therapy and develop into kids who can attend kindergarten or 1st grade.

What is really sad is that for the kids that don't get early intervention and where schools and states are not able to identify these kids. These kids end up with behavioral IEPs, might get kicked out of school and have no friends. Not that the kids necessarily want to play with other kids.

Also the UK is seriously behind in autism therapy services and while it is good to focus on positive traits that might be associated with autism it is not helpful to those who really need the help. And in many cases you need a lot of help. But if you invest when the kids are young you can really make a difference.

In the US, Obamacare really opened up services in the US and even then its hit or miss. For example, federal employees have no early intervention/autism coverage. And before that you had to go to specific states or school districts or be really rich to get any type of help. Even then it takes 6 months to get your kid in somewhere and the wait lists are huge as demand is so high.

Kids with autism basically need 1:1 therapy 8 hours a day with positive reinforcement either ABA, AVB etc... I am a fan of center based programs but you do need to find a good program.

https://www.autismspeaks.org/signs-autism

Also I am not sure what Baron-Cohen is suggesting here but saying that there is a "scientific rationale" behind the kid flipping the light on and off or staring at the fireplace or a ceiling fan wondering how it is just nonsense. I mean maybe its true but did the kid tell you that? The kid is presumably not able to ask someone as to why the light turns on when he flicks the switch or if told, integrate the response. I think it is more consistent with the need for stimulation. Also his comment on a savant with autism is really not helpful. Savant syndrome is probably co-morbid with autism, development delay, and intellectual disability... but to say that's an autistic trait is just irresponsible.

His book is basically a generalization based on autistic traits focused on systematizing and pattern matching and guess what the major confounding variable is ... we are all humans. Humans are pattern matchers + more. We also all respond to stimulus/response. And even animals are pattern matchers.
I think it comes down to the specific codebase for the Clojure version vs. the Rust version. In this case, after rewriting the code into Rust it was easier for the author to understand and reason with.

Not that you can't do it in Clojure or any given language.

In the end, they're happy with Rust. I really like what little Rust I've done. I still reach for JS/Node first only because I can get something working faster often because of what's in the box and in npm. It's far from the most performant, but often fast enough. C# tends to be my second level, though as I become more familiar with Rust, it may displace this.

You can't be an expert in everything and sometimes a given language will lend itself to the way you think in idiomatic terms.

The article is an anecdote on a personal experience, not an assault on Clojure or the ecosystem. Even if it is critical at a couple points.

IVy was exactly one of the things I had in mind. Other examples would be checking liveness properties in the unbounded case, and possibly full Linear Temporal Logic, e.g., <>[]p ("eventually, property p is always satisfied").

I realize this is a tall order, but I think nuXmv [1] already implements some kind of SMT-based LTL model checking, so it should be possible to achieve something similar for TLA+ (or at least a subset).

> to make invariant checking decidable

Of course decidability is desirable, but efficient sound procedures in the undecidable case would still solve many practical problems. I realize they are not as "nice" from a theoretical/academic standpoint, though.

I agree, the turn signals suck. Though interestingly I don't have the same problem you have. What gets me is that the detent between the momentary switch and the full signal is stiff enough that I somewhat regularly inadvertently flash oncoming traffic when activating the turn signal. Because the pull resistance on that stalk is much lower than the pressure required to overcome the signal detent.
Seattle.

I have 3 major grocery stores (Safeway, QFC, Target) within 15 minutes walking from me. And at least 20 bars and restaurants within the same distance. Public transportation to downtown takes about 35 minutes, which isn't great, but it's okay. Uber works well if you need to be faster.
