I’ve been dying for an AutoLayout for web — can’t wait to try it.

Just curious - at what point does someone “grow out” of this tool? When you say Abstra is great for MVPs in production, I assume there’s a next level not served by this tool?
Validation in the browser is just a UX thing. There's no security in the browser.
The thing is, I would expect every individual "intervention" to be modelled by its own model or equation (whether or not it's literally an equation is irrelevant, at the end all system dynamics are governed by equations), each of which has presumably been backed by some scientific research.

For instance, if bees are getting afflicted by some fungus, then there is some research that says that applying fungicide X will allow the colony to prevent y% decline in the ideal case, or whatever.

At that point, even though the model will then incorporate this "sub-model," you don't need the system dynamics model to say what will happen when you apply the fungicide, you only need that well-researched sub-model.

I feel (and I'm getting a little out of my depth because of my limited research on real-world uses of these models) that the system dynamics model is only useful for attempting to determine what happens when you have a conjunction of various interventions, or interventions with various environmental parameters that were outside the original research of the sub-model. But that's precisely were the limitations of the system dynamics model will come into play, because the non-linear or chaotic effects may mean that the model's prediction that the colony will grow or fail may have little to do with reality, because of the complexity of accurately accounting for so many parameters, and guessing how they interact without specific research on how they interact.

With that attitude, I’d happily invest in whatever it is you’re creating. Looking forward to hearing about your success on HN at some point.
I don't think it works this way with HIV. As you stated having immunity to a specific HIV presentation does not prevent infection. Any vaccine effective would need to make the body see a pattern it cannot find on it's own. Something universal to HIV, which cannot be evolved around.

This is different from other disease where the immune system doesn't have enough time to response before the disease kills/damages the body.

If the vaccine can prevent HIV signature evasion, it may very well help control/treat the disease, I think.
Your experience may be different, but I know surprisingly many such people in my circles. Usually engineers, doctors and other white-collar workers, who got to the point where their job is more satisfying than stressful. They don't do it for the money, but to socialize and to have a purpose in life.

How do you handle arrays of values where the array lengths are not a multiple of 8 in this kind of vectorized code? Do you zero pad them before handling them to the vectorized function, or do you run a second loop element by element on the remaining elements after the main one? What happens if you try to do `_mm256_load_ps(&ys[i])` with < 8 elements remaining?
Yep,
I spent a lot of time working on business ideas and building out entire SaaS apps only to realize I absolutely hate the people and the industry and would be embarrassed to be associated with them, even though it can make money.
But even this is an example of finding 'a' (not 'the') right set of primitives as APL is from 1966.

Vaccine for coronavirus recommended for its immune-building benefit even in persons who had infection, this is to reduce likelihood for more infection in the future. I am doubting that this applys on the HIV since nobody is getting it then beating the infection, just supressing it.
I am happy someone worded it for HN. Here in the trenches, we constantly mock the blatant “inaccuracy” (intended bias) of corporate information, but there is a disconnect in society with people who have never been confronted with the systematic bias of some topic in the media.
The same reason scientists don't write books to debunk pseudoscience. They don't sell and a negative is nearly impossible to disprove.

Frankly, the correct information is mundane while the conspiracy claims are much more fun--ready made for the bored and unfulfilled, just add belief.

> Are holidays really a big thing? I know flights are technically hard to decarbonise today, but I don't think I've ever seen numbers suggesting they're a big priority compared with the low hanging fruit or that individual action is the best way to solve it.

But leisure travel is an extremely low-hanging fruit when compared with e.g. food, isn't it? Nobody has to take a vacation by plane, but everybody has to eat.

The tourist industry is pretty wasteful and similar to the fashion industry: it's pretty much entirely unnecessary luxury. Compare that to e.g. concrete manufacturers or farms, they're not only necessary, they're pretty far from the top of the pyramid: you'll have a very hard time without them.
I know a few people who met through tinder. Some had sex supposedly, some got married and became parents which is a good proof of them having sex from my non expert point of view.
How do you decide what the 'standard American accent' is?

I spent some time on a remote team working with a great group of folks from the US South. I'm Canadian. I picked up a lot of accent changes that stick with me today ("y'all" is the best plural second-person pronoun ever).

But even things like California vs New York, there are differences. Urban vs rural. Minnesota vs Florida.

There are interesting implications in how you make those choices. ie: "Well, however I speak is correct" will get you elitism accusations I'm sure.
When people argue that there shouldn't be a downvote option on HN, this is the type of comment that I'd point to as a counterpoint.

It's the same type of populist drivel that led people to believe that they are fighting for their freedoms by rejecting food standards, environmental regulation and vaccinations.

Everybody has an agenda. At least with large centralised organisations their position is relatively clear, compared to the murky dark money world of political influencers. Not taking sides, but this approach to the topic is absolutely toxic to civil discussion.

> The end effect is that CSS isn't approachable for even seasoned graphic artists let alone laymen; another effect being browser complexity resulting in monopolies.

This is so true. CSS has become a multi-headed Hydra whose parts appear completely unrelated to each other. I've been a developer and designer for more than 20 years and I have no idea what the parameter names and orders are for position, versus grids, versus float, etc. It's parameter soup. Who said the hardest part of programming is naming things? The CSS folks didn't get the memo.

To do any real work with CSS means you have memorize a bunch of conflicting weirdness and/or keep a reference page open at all times. The idea of CSS frameworks to simplify or fix this doesn't work because, in order to write or debug what you create in those frameworks, you must know regular old CSS!

It's turtles all the way down.
Kay is looking at a microscopic part of a vast and evolving ecosystem.

Take a look at deep learning, Kay. (In a sense, building models is a new type of programming, solving problems that are difficult to describe.)

Or maybe something a little closer to home, like Rust. It vastly improves the state of the world at the boundaries of the software layer.
You're going to struggle as a novice if you're quick to form opinions about things that you don't fully understand, especially if those opinions involve rejecting wildly popular tools used by people with far more expertise than you have.

People who understand React/Vue/Angular are free to criticize them (and have many valid reasons for doing so), but when you do it after following a beginner tutorial or two, you're just being ignorant.

How do I know this? Because you're criticizing React for forcing you to "do everything through a JSX template" and "debugging through a transpiler", which tells me that you aren't aware that React can be used without JSX and without any transpiling.

Since that information is available to you on about the fourth paragraph of the "Getting Started" page on reactjs.org, you clearly haven't bothered to learn much about it at all.

Going solo could fall into two different writer-style idioms: Stringer vs Novelist. A Stringer is a freelancer that writes a news story. The content is short term and quasi-anonymous. A Novelist spends months writing something a bit more epic, published under their own name.

On several occasions I've tried going the Novelist route. The problem is when the money runs out and you revert to becoming a Stringer to top-off the bank account. But, then you return back to your project and find the APIs have all changed. So, there is a lot of refactoring to do.

For iOS, there is also the aspect of APIs becoming more team oriented. I met an Apple engineer and asked him what he worked on. He mentioned a very narrow aspect of one API. I asked him what else he worked on and he said that was it! In contrast, I have to juggle hundreds of APIs. There seems to be a conflict of mindset.

A counter example was from an Uber driver in San Mateo. We struck up a conversation and I mentioned that I'm an iOS developer. He showed me an app that he wrote in Flutter to track all his rides. He was on the verge of marketing it. I was kinda blown away.
I'm not sure that it does all the time, or perhaps people are turning off the distance setting?

I've certainly matched people who are far away, despite no desire to do so.
I would say that you have to think in a different style so would classify as a different paradigm and not just syntax.

I am under the impression it is staff related and not physical capacity and one of the reasons is a high level of RSV. The state deals with a lot of folks from Mexico and Central/South America that are not vaccinated and bring waves of controllable disease. A few years back they had to deal with a wave of Whooping Cough that was imported from unvaccinated children from Mexico.

I have been writing Clojure full time since 2017. Most of my work is about building mobile/web apps and APIs.

Ferret Lang is a lisp that I dig. It compiles to C++11 and is crazy fast on low powered hardware. Coming from Clojure, Ferret feels nimble. But I don't think I'll ever have a use for it.

Can we take on Postman for API testing?
My name is Mats, and I'm the CEO of Boozang, a browser-based test automation platform. We recently decided to make our API testing FREE.

What would it take, in your opinion, to compete with software such as Postman? What are the must-have features in Postman that are lacking on our side, and what, if any, would be the advantages you see with the Boozang web approach?

You can find an introduction to our API testing here:

Climate change skeptics will talk your ear off about why climate change is a hoax - you literally can't get them to stop telling why you should make no change whatsoever to your life.

Climate change true believers, on the other hand, refuse to waste even one single word convincing the rest of us as to why we should all drive electric cars, stop using straws, and not run our air conditioners in the summers - things which, if they're serious, are necessary to ensure the survival of the species.

That observation alone makes the skeptics look more compelling.

most tours are given by undergrads. what kinds of questions about academics do you expect them to answer? outside of their own major, they probably don't have any information you couldn't look up on the website.

this ties into (imo) one of the bigger problems with college education. even if you introduce them to someone who is knowledgeable about the academics, your average 18 yo and their parent aren't really in a position to evaluate the responses. reputation and campus life are the only aspects of college that are easily understood.

You should provide evidence, and when you go back and edit your response to do so, that evidence should be relevant to the discussion at hand.

There's a huge difference between data on a disease that's been studied for over 40 years, vs one that's only been around for a few months.

If you think the CDC got it's facts wrong on Lyme disease, it's as simple as saying "This source disagrees", and provide the source. Jumping to the conclusion that your unnamed source is more accurate than any other is another problem itself.
I assume the effectiveness of PrEP doesn't help the case, as infection can now be prevented for those at high risk.

Wow, i think this might be a standup routine.

Have you ever interacted with facebook crazy people? People shouting at you their 'research' with smug superiority is one way communication not a debate.
That depends. Do senior CDC or NIH staff stand to collect patent royalties on its administration? The former (and probably informally mandatory). If not, then the latter. Given Stéphane Bancel's and others' recent trading, then I wouldn't bank on this one being a winner.
Hmm, so this 900 megawatt hour lithium installation will roughly use about 73 metric tons of lithium at 0.3 grams per amp hour. World lithium production is about 82 thousand metric tons with plenty of room for future expansion.

Using a single year's supply of lithium we would be able to produce 1 terawatt hour worth of battery as an upper limit. Currently the world uses about 64 terawatt hours daily on average. Assuming we would only need storage for 1/3 of that amount, we would need roughly 20 terawatt hours of storage.

What this means is we would need to dedicate 20 years worth of current lithium mining to produce the needed batteries or expand lithium mining by a factor of 5-10 to meet climate targets.

Back of the napkin, this seems practical in the long run, but difficult in the short run. With recycling we can build up a reserve of lithium over the years, however I think it's going to take half a century just to get the lithium we need to replace fossil fuels. In the meantime we'll take a small chunk out of fossil fuel demand. However demand is still increasing.

We may want to consider subsidizing nuclear at this point to get us over the finish line on renewables. Unless we come up with another carbon neutral energy source that provides consistent power 24/7.

I prefer OkCupid, because people have space to write a lot more, and you get a better idea of personality. On Tinder it is all about the photos, and little about the personality until you've matched.

But it has to be said I've had far more meetups with tinder than anything else. Here in Helsinki it seems to be pretty popular. Maybe I stand out because I'm a foreigner, wearing a kilt, but I guess I've been quite lucky in that I get matches pretty frequently.

(Though I go through phases where I ignore it for a few months, then use it for a few hours every day in a week.)
I think the difference is faith in authority figures. People who trust those in authority will believe what they're told (quite correctly, in this case), but they won't understand the full argument--they're not authorities themselves. That is, after all, the whole point of having authority figures and experts: the world is far too complex to understand everything yourself.

People who don't believe the authority figures need a reason _why_, and will concoct something. They need to validate their skepticism, both to themselves and to others.

If a skeptic really wanted to understand the argument for the COVID vaccine (in this case), all the information is out there to be had. But to really understand it they'd have to become experts themselves--actual experts, with an understanding of epidemiology, statistics, immune responses, and so on. Years of study. A google search that points out a few problems in isolation doesn't cut it.

A certain degree of skepticism for authority is definitely healthy, but I'd say it borders on pathological in modern American society.

I’ve been making a “toy” SaaS website solo, both as a dry run for future endeavors and as a way to practice broader tech skills than my day job requires. (“Toy” = real website, but not one that I expect will make more than a few hundred dollars per month at max.)

Anyone who’s been down this path have any lessons learned or general resources you found helpful to share? It’s been smooth sailing so far, but the place that I’m running into a lot of unknown unknowns is legal compliance: what do I do besides form an LLC, write a privacy policy, etc.?

Great, thank you!

The next level is "complex apps" because code is still a better way to create customized abstractions.

That said, you can scale simple/CRUD applications with Abstra for tons of users without having to mind about infrastructure
Definition by function/combinator composition isn’t weird to a modern programmer (Haskell does a lot weirder); and vector processing isn’t really weird either — even Java programmers are familiar with chaining transformations and reductions on Streams these days.

Instead, not knowing J, the only† thing that’s weird about that J expression to me, is that both +/ and # are receiving the same implicit vector argument, without any Forth-like “dup” operator needing to precede them.

Are these operators defined to take an implicit single receiver vector? (Maybe whichever one’s on top of a “vector result stack” separate from a “scalar result stack”? Maybe the first one passed to the implicit lambda expression this code would be wrapped in?) Or is syntax sugar here hiding the argument, the way Smalltalk hides the receiver in successive expressions chained using ; ?

What would a compact-as-possible J expression look like, to sum up the contents of one vector, and then divide the result by the cardinality of a different vector?

—————

† Well, there is one other, more technical thing that’s “weird” about the expression above: it’s the fact that, unless +/ is a identifier separate from +, then the lexeme-sequence + / has to either derive its AST by lookahead, or by + being a stack literal and / an HOF. But then % is, seemingly, a binary infix operator. You don’t usually find both of those syntax features in the same grammar, both operating on arbitrary identifier-class lexemes, as it would usually cause an LALR parser for the language to have shift-reduce ambiguity. Unless, I suppose, the lexeme / isn’t lexed as “an identifier” terminal, but rather its own terminal class—and one that’s illegal anywhere but postfix of an identifier.
