> "screen time" is too vague

In a world where most adults of the current generation spend almost more time in front of the screen than away from it, one would indeed think that "screen time" means nothing in and of itself.

I think we also completely fail in every way to measure the benefit — because adaption, evolution tells us one thing: while there are "better" and "worse" paths, it's only ever retrospectively; the corrolary is that it's almost impossible to actually predict evolution, to "design" it — it's sci-fi, for now. So I've always been wary of applied fields faced with a paradigm change, in history: they always tend to lag a lot, even more so than people outside the field — perhaps because they're so deep in it that they can't see what's obvious to a bystander, idk.

Note that it's healthy, in science — skepticism is what makes us great, in a way, because we don't condone "intuition" as "theory" unlike any other endeavor of the human mind. But science is not up to predict individual let alone social evolution, a far, far cry from it that's even on the side of "maybe's" in some abstract idealistic future.

Right now, we're left with trying to make the best out of what we've got to prepare kids for a future we can't see ourselves, and we probably take a cue or two for our own life in that process — I'll let you be the judge of whether parenting is a learning experience...

My intuition, deep down, is that a reasonable¹ dose of exposure to technological tools is very desirable in developing one's fluency with said tech; and may constitute one of these hard to measure but clearly obvious — you "know it when you see it" — difference between "nerds" or "geeks" and the "computer illiterate" (which, I observe, are less but still many in the millenials generation compared to X and boomers, contrary to my initial intuition).

Generally, I think one should trust each step of the way their "gut feeling" about the development of their children, and adjust accordingly, remain in a "safe zone", sane defaults when in doubt. It's also been shown to a convincing extent that "just trying hard, for real" and "showing up, being there" and being very human in simply trying to communicate with children, is as sure as we have of a recipe for success — because it's bound to be very relevant, very ad hoc to your own situation, and thus that of your children. Go against the grain if it makes them better if your eyes and in their experience of life, just don't ignore hard facts from other parents as well.

¹ By "reasonable" I mean not impairing other development; but it's also "reasonable" to envision that some skills are less useful nowadays than 50 or 500 years ago (despite the brain's ability for them, and our ability to measure abstractly relevant "improvements" or "impairments" here or there). Conversely that some are more useful, but we may not yet test for these.
The free market would never build this without the government paying, because most patients can't exactly afford to pay for their share of the construction costs. For-profit hospitals are incentivized to turn away patients showing concerning symptoms to prevent them from infecting their paying customers.

There are many lessons that can be drawn from this, but "privatize everything" is not one of them.
Yea, I think this is an interesting approach. But FreePDK45 slides mention that it's not designed for manufacture, and there does not appear to be an easy upgrade path. So you could design a chip with FreePDK, release the design, and then redo the whole thing in a vendor PDK.

I talked to someone who worked on AsicOne, and he said that even if you make your own PDK and draw your own transistors and everything, you'll still have to sign an NDK to do the sign-off and what not. I'm not intimately familiar with the whole process myself, but from what I understand it is basically impossible to have an open source analog design that you can actually manufacture. (sure, you can make a theoretical toy thing, but if you can't manufacture it, who cares?)

I'm perplexed at what "AIP Advances" is supposed to be. This paper isn't an advance of any sort. It's an application of some decades-old formulas you can grab off Wikipedia; a high schooler could apply them to get this result. It adds nothing to "testability" (and is in fact wrong in its understanding of what "information" in a hard drive really is).

The journal has an impact factor of 1.5. For comparison, Science and Nature are in the 40s. This was a cute letter, but it should not have passed peer-review, whether it's open-access or not, because it contributes nothing novel.
I can see how this is possible, but I've never experienced it. On the contrary, I see people just do and do and waste effort and redo because of things that could have easily been foreseen with a plan based on input from all stakeholders. Meaning, yeah, I see someone make a plan on their own and inflict their plan on others, but that is just a bad plan.

> Yang is polling at 8% nationally now.

Yes, there's now been published a single poll which has him outside the MoE of zero. (Not outside the MoE of his polling average for any month since October, though, and statistically you'd expect with the number of polls at least one with him at 8% if he was just hovering at 3.5% for this long.)

While that's a landmark, I guess, it's a thin reed to ground a conclusion of any, much less rapid or exponential, progress.
I think that's partially true, I feel like I find the weirdos like me wherever I go and we just get on. I'm also not great at climbing the corporate ladder, but, I really don't care as long as I'm growing in what feels like a positive direction for my life as a whole.

Well, most of the other theories back then would seem ridiculous and obviously wrong nowadays. That's the nature of theorizing when you have little information.

Obviously we mostly remember those theories that turned out to be right.
Perhaps "mating" was the wrong word - the goal is not always to have a monogamous relationship with kids, but to attract higher perceived quality and quantity of sexual partners.

>people say this all the time but poor people are having kids at a much higher rate than rich people so the theory doesn't pan- if your goal was to have kids you'd stay with your high school
sweetheart.

The theory definitely pans.

You just tried to make it fail by putting the cart about 500 miles in front of the horse. Many accomplished people don't want kids at all and if they do, they usually don't want a lot of them.

If they wanted to have a bunch of kids they could.

They're not "losing" to people in third world countries by not having kids.

I wouldn't judge theories based on who made them. Judge them based on their own quality, logic and evidence.

And it's critical to realize: mocking others for engaging in the Importance Game and the Leveling Game is just a way of engaging in the Importance Game.

This is an even stranger game than Nuclear War: it sometimes seems that the only winning move is not to play, but not to play isn't really an option.

Germany absolutely is relying on coal and (Russian) gas to afford its ideological decision to prematurely sunset nuclear plants, at the worst possible time in history : just as climate change becomes an emergency.

The cold hard truth is that it's impossible to operate a grid with solar & wind energy alone, unless and until a hypothetical battery storage breakthrough lands in the next decades.

I've just checked the realtime figures and as I write this, German electricity is 5 times more carbon intensive than in France (72% nuclear) : https://www.electricitymap.org/
Haskell doesn't stop you from doing IO everywhere. Do pointer arithmetic with in-place mutation if you want. Segfault it if you want.

The "over-zealous axioms" you refer to can be boiled down to: if you do mutation in a function, don't give it a pure type.
If the area is officially locked down, blocking transport by land, air, & water, how are they planning to deliver the masks?

I assume there are exceptions made for appropriate officials and medical personnel, if adequate quarantine rues are followed, do the group attracting the crowd funding have access to this channel? Or drone based deliver perhaps (assuming they don't break the transport in/out rule despite not being manned so not presenting the same infection spread vector)?

I'd like to know the masks are going to go somewhere useful, rather than being blocked by the rules and distributed around officials instead of to hospital staff & patients and the public, before I donate.

1-2 short stints early in your career don't mean much.

What's important is that you leave for a better job. Focus on where you're going, not where you're leaving. (I once took a job with a few too many warning signs, and in hindsight I should have stayed put.)

Honestly, every person filtering resumes has different things they look for. For every person who filters you out because you had a short stint, there will be someone who filters you in because your new job looks so much better.

Oh, and good jobs have ups and downs. If you generally like the work, believe in the company, and like the people you're working with, you can figure it out.

If you think that playing 'to lose' is somehow opting out then you're fooling yourself. The point us that we are always playing.
The article takes a strong position.

The article devalues finite status games based on victimhood or individual merit. It goes on to suggest hierarchy as a direct counterpoint and goes on to articulates the virtues of a class based system. It claims as it's final conclusion left with the reader that there is a conflict between needing to value someone's life in terms of worth at the bottom of society and at the top. Something only a hierarchy can solve or would even attempt to order the world that way.

A hierarchy can solve this because it is a unified system of receivership centered on a common purpose. At every level it is the same purpose executed better or worse, differing on the properties of the person involved. A hierarchy supports the concept of a 'best', an 'elite' rather than merit and hides all counter-veiling evidence under a shroud of embarrassment.

The UK has implemented a hierarchical class system. I am articulating what happens when you live in a class system. A lot of things people don't talk about. Some people want to live in the shade of a great tree, and I'm okay with that. I don't.

I disagree. In practice the things I can do between Cython, llvmlite and numba are very low effort, wide reach optimizations. Practically, I have never found a case when a feature of Julia would have made this much easier for me. As a result, the tradeoff of Julia continues to be 100% focused on the switching costs, infrastructure maturity, drop in equivalents of well worn Python libraries, etc.
Reversing XignCode3 Driver – Part 3 – Analyzing Dispatch Functions
Yes, learning other paradigms is useful.

For me, introducing immutability of data (functional paradigm) helped clean up many interfaces and made the code feel resilient. I realized I rarely passed the input data back to the caller (it was often a new and different structure). At the end of it all, I was somehow more confident in the 'run time' of the app and reasoning about issues is much easier. Currently I am not using any language features to enforce immutability - I just code the receiving function to not change any input structures (or in rare cases, return a new one). I suspect there are some exceptions lying around but having most of the code behave this way has helped.
The biggest problem I had with Mint and investment accounts was that they were flaky, and always had some type of issue connecting. Personal Capital on the other hand works flawlessly with them. Conversely Mint seems to always work with other things like credit cards, while I run into issues on PC sometimes.

If you do several targeted searches like this in a month LinkedIn now blocks the results and says "Looks like you are a power searcher, upgrade to premium to see results". It even blocks the "people also viewed" results on individual profiles. Makes it nearly impossible to actually find a number of specific recruiters.

Sounds totally fair and reasonable to the people who get crazy high bills for the one thing a year that they need it for, despite paying hundreds a month in premiums for the "privilege" of also paying for people who can't. What a system.
5 Useful Tricks You Didn't Know for Git
It doesn't matter as the messages are end to end encrypted and the way it is done is continously verified by multiple leading/up-and-coming cryptographers as far as I understand.

This is the huge advantage that Signal has over mail, the default mode in Telegram and pretty much anything there is: it does matter if NSA, FSB, MI5, Mossad, Google and Facebook all have root on a server that all the traffic passes through. To the best our knowledge - long as they don't compromise one of the endpoints - the only thing they'll get is metadata and the only thing they can do is disrupting the service.
There are lots of catches like this that make life difficult to the poor and vulnerable in our modern society. Most of these catches are some status obtained and managed through privatized means with little-to-no oversight that are becoming more and more fundamental functions of daily life as they are abstract processes to follow leading to obtaining necessities: food, housing, healthcare, etc.

The vast majority are never exposed to these institutional barriers because they are financially above those barriers but for working poor, poverty stricken, etc. these are daily challenges to deal with with little or no recourse of action.

Take paying utilities as an example. For most it's as trivial as logging on your phone one time and setting up the account with auto recurring payments on a credit card--then setup auto payment of your credit card from a checking account where you have some portion of income automatically transferred to.

For others, they have to carefully pick and choose when and what to pay and make sure they can pay cash, check, etc. There's all the additional overhead too: traveling to a valid payment location or the post office for stamps to mail things in, cognative load/stress for keeping track of the schedule or putting it down on a calendar, etc. That's just paying utilities. Plenty of other processes have all sorts of other headaches.

In most locations in modern society, owning and maintaining a vehicle is a necessity when factoring all alternatives (aside from moving), yet vehicle ownership considered a privilege.

This list goes on and on. It's no wonder many Americans are not happy.
They're inaccurate, but they're fundamentally fate altering when you can put some pieces of information together to generate a non-obvious conclusion that prevents a huge disaster. Good planning is not about assuming something works, that's where most of the time the plan is wrong, it is to assume something doesn't work, and what can be done to forge ahead in such a case. Good planning is also revising plans any time new information is learned.
> The truth is that the Haskell compiler will never be able to automatically translate idiomatic Haskell code into something that’s competitive with C

I don't dispute this. My problem is that people will use this as a reason dismiss Haskell, and then use Python.
From the user's perspective, the funnel can have several stages before they even arrive at your website. E.g. becoming aware they have a problem, researching the problem in general and what approaches have been tried, deciding which type of approach is applicable them, comparing different products. An organic search is likely to be in one of the earlier phases, but a paid search campaign can target keywords indicative of later phases, as well as different value propositions.

This user-centric idea of a funnel is different than the website-centric view of the funnel where you start with a landing page and end with a lead form or purchase. The phrase "Customer Journey" usually gets bandied about to refer to the former, although it also often gets bandied about without referring to anything at all.

One could perhaps draw a distinction between languages that were designed from the ground up as multiparadigm, such as OCaml, and languages that originally targeted one paradigm and then became multiparadigm by katamari-ing up a bunch of extra features, as Python did.

FWIW, I also don't know that Python officially conceives of itself as multiparadigm so much as as a procedural language with classes. Kids these days forget that higher-order programming has a long history in procedural programming, too. ALGOL was doing it in the 1960s, after lisp but a good decade before Backus published Can Programming Be Liberated from the von Neumann Style?.
