So very true. The ideas mentioned in the article does not sound appealing to me:

"In this picture, the curvature of space would constantly fluctuate on extremely small scales, well beyond anything we could hope to measure"

"Her model is based on the idea that extra dimensions, beyond the three of space and one of time that we witness, might be hidden out of sight."

Instead of cosmological constant "novel" approaches relay on something that could not be observed, even in principle. That does not sound like a good approach.

My guess is that they try to make some assumptions, figure out math around it, hope that it will somehow stick nicely, which would give hope that there is something in it.

Indeed, it seems that math "likes" to describe our universe, some mathematical theories (Riemannian geometry, group theory) fit physics wonderfully. The problem is that for physics math is just a language, it is unlikely that language alone will give us answers without understanding physical phenomena itself.

Nice series! I've considered doing something similar due to the dearth of decent material on FPGA and hardware design on the internet though never quite got around to it...

For the sprites did you consider a part on dealing with multiple overlapping sprites? (I just skimmed, so apologies if you did this somewhere and I missed it!) There's at least two approaches here and I think it's an interesting thing to explore to discuss design trade-offs.

The two approaches I can see are:

1. Load the relevant line of each sprite into flops during the blank interval, when drawing determine which sprites produces a pixel for a given output pixel then apply ordering, taking into account transparent pixels to determine which one wins. You have a simultaneous read of all of the sprite flops each output pixel to do this

2. Pre-render all of the sprite pixels for a line into a memory buffer during the blanking interval. If you have multiple sprite pixels per cycle from memory and take advantage of that fact your FPGA can probably run at some multiple of the pixel clock (say 100 MHz vs the ~25 MHz pixel clock for 640x480) you do quite a lot in the blanking interval.

I reckon 2 wins when you're wanting more sprites per line and higher bit-depths per sprite pixel (8-bit 256 colour sprites vs 2/4/8 colour sprites).

I've got a ~60% complete version of 2, maybe I should follow you lead and finish it off and write about how it works.

Hospital - people will move there for a perceived openness to alternative drug therapy (however you want to interpret that), perceived safety nets including addiction treatment advantages.

Suffering from addiction - friend, I came of age in the nineties, and had friends hooked on everything you can imagine back then (and did my share). I’ve had friends die from and survive overdoses. I’ve done CPR on a man dying from an OD in a public restroom within the last three years (who lived, incidentally). The last close friend that died from an overdose was only about five years ago - a highly functional businesswoman. I’ll tell you this, a lot of people suffering from addiction don’t know or care that they have an addiction. Not every drug user thinks themselves a victim - in fact those that do, IME, are the exception, not the rule, but I’m sure that varies with time and place. Will those people that do move to Oregon? Probably not, but I’ve known a lot of personalities that would travel there for the fun of it, and wouldn’t be surprised if more than a few die there too.

I perceive by your comments that you feel very earnestly about the upside in this policy. I have no dog in the fight, and respect your hopefulness.
I made this iOS game:

I have wanted to be able to play this game for a long time, and probably thanks to pandemic, I did the work to enable it to be shared with others. It has made a grand total of 3 sales this year, and that isn't really bothering me (the main frustration is the apple developer fee...)

How surprised would you be if it turned out we really did live in a multiverse? Would you expect things to look different if we did? Do you think it's extremely implausible a priori?

I find multiverses far more plausible than futzing constants, because the universe in general seems to be absurdly big but simple and consistent physics-wise. Smaller but more fiddly/complicated models seem much less plausible, just judging by history.

Well, ads does afford them the luxury of trying new things, develop new products and revenue sources. Google is just pretty poor at developing new products.

It is actually pretty fascinating, short of cloud computing, and Gsuite, Google doesn't appear to be able to produce products that people will actually pay for. It's not that Google doesn't have success stories, they do, Android for instance. They just don't seem to be able to sell anything.

Was going to say. Most of the times all it takes is to have a proper data model.

For analytics I favour de-nomarlized schemas and, if necessary, nested fields. Queries are much easier to write (fewer joins), much faster, no need to incrementally materialize (sigh), fewer backfills and no messy field definitions.

What you often see instead is highly-normalized data models with an un-trackable amount of materialized views (usually on top each others) and some complicated tools/solutions to try to deal with all that mess. The cost of a bad design.
Were there some serious mental gymnastics coming from Fivetran yesterday, or am I missing something? The CEO had a data lake hit piece in Forbes ('The Business Case For Ditching Your Data Lake'[1]) and almost simultaneously authored this 'Databricks' Delta Lake is not a data lake' blog.

Felt like the CEO wanted to make a strong point, but has a relationship with Databricks that he didn't want to undermine, so did some reclassification gymnastics to make it all fit. But I am probably too cynical.

Finally, I beg for mercy from the 'lakehouse'. It is a bridge too far ;-)

> 2) Aren't these theories reasonably falsifiable insofar as they'll eventually result in experiments designed to map out the possible domains of the space? eg, what if we build a much higher energy collider and finally find real evidence of the super-symmetry particles?

Would you treat not finding super-symmetry particles as falsifying those theories? AIUI those theories admit the possibility of such particles but also the possibility of such particles not existing, so they're not actually falsifiable that way.
Having now actually looked at the code looks like you did a version of 1, but as you've only got 1-bit pixels the combination stage is trivial (of the 8 sprites are any on, if so output a sprite pixel)?

I highly reccomend the Podcast "Your undivided attention" by Tristan Harris. Together with experts he explains very detailed, how algorithms and social media affect our society.

Big changes have been made trough technology.
And many of those changes have a negativ impact on our society.

But I strongly believe that humanity can overcome those problems. Altough it may seem impossible from time to time.

Science is defined by testability. A theory that can't be tested is just pseudoscience, unlike a theory that just can't be tested right now due to technological limitations.

Hey! JP from Opstrace here. Thanks for reading through things and for sharing your thoughts. The quick reply is that we still have to introduce a proper cluster config diff and mutation design.

An `apply` command might look innocent on the surface. But. Upgrades (including config changes) are hard. Super hard. If it's helping a bit: the entire current Opstrace team has dealt with super challenging platform upgrade scenarios in the most demanding customer environments in the past years. We try to not underestimate this challenge :).

We're super fast moving right now and didn't want to bother with in-place config changes (as you can imagine, we wouldn't really be able to provide solid guarantees around that). We'll work on that and make it nice when the time is right, and when we feel like we can can actually provide guarantees.
Huh, that's weird. They don't usually let me talk to people, so I'm not sure what the best workaround is there. :-p I'd say go ahead and trust your instincts and be clear about it.

PS. I was expecting the kind of answers I received... as the whole subject stinks, talking about it stinks even more. What I wasn't waiting is to see people, in another time caring and loving this OS quietly yielding about such a big insanity. Thinking right now specially about Debian and ArchLinux mantainers.
It would be oddly specific, IMO, to claim that a country doesn't spend enough on (for example) social security. What people actually talk about is outcomes.

Interesting that a lot is spent on it, but not really much of a counterpoint since, as you say, it's done so 'uniquely inefficiently' that the outcome remains less.

I feel like equally as many people rejected Pinker because it violated their priors.

I don't have a strong opinion one way or the other -- I guess my prior is that I am skeptical of broad narratives one way or the other and I think Pinker is prone to facile generalizations -- but most of the rebuttals I've seen to Pinker seem offended by the idea of progress, rather than taking his arguments seriously.

Why? Evaporation humidifier won't make more noise when they're empty, and water level detection is surprisingly hard to make reliable while still being convenient in consumer devices. And you have to refill them daily anyway, so using it as an 'empty' indicator doesn't really add much (in theory it does, but not in real use). At best one could say it's the energy savings, but for a device that requires daily maintenance (refills) I'm not sure if the benefits outweight the advantages.
Robinhood CEO explains to Elon Musk why his platform restricted trading last w
Quite poorly reasoned, the author errs by not understanding the difference between thinking and reasoning. Reason has a long philosophical tradition but simplified for this context reasoning is thinking with reasons, so if something is easier to reason about it is providing your with more explicit reasons for why things are happening, regardless of the paradigm and style. Is that necessarily better? No, but in most contexts it is. Can it be used deceptively, yes, everything can.
I like notebookcheck's reviews as well.

The only thing missing are confidence intervals

It'll kill the whole world - eventually, but for an effective first or second strike you want to take out the enemy as fast as possible, instead of wait for the fallout and climate change to take over.

Mine is sword making, and I will share the results with people doing it full-time and also the local HEMA people. Once I am done, so. That will really take a while, due to injury and time constraints. The material is there already!

The most tricky part is heat treatment. The only supplier I found able to treat sword blades, due to length, is using induction hardening. On paper, that seems to be a pretty good way doing it. Penetration depth can be controlled, almost no deformation. Funny thing is, nobody seemed to have tried it so far. Curious to see how it works out. Maybe I make a blade for destructive testing, but we'll see.
No, not necessarily. Curried functions have their own problems because they are missing the vital parameter names. But that's not what I meant. Think of the classic memoization example (written without a compiler at hand...)

let createMemoizer f =
let cache = Dictionary<_,_>()
let f' = fun x ->
match cache.TryGetValue(x) with
| (true,value) -> value
| (false, _) ->
let result = f x
do cache.[x] <- result
result
f'

The signature is ```createMemoizer (f:'a->'b) -> 'a->'b```, which is not very telling, especially if it is returned by yet another function, so that even the createMemoizer name is lost. In classic OO, I'd just get a Memoizer object that carries vital documenation and what not with itself, as it is passed around. It's no even that much longer, it's just not as elegant to use.

class Memoizer<TINPUT,TOUTPUT> {
Dictionary<T,TOUTPUT> cache = new Dictionary<T,TOUTPUT>();
Func<TINPUT,TOUTPUT> f;

/* ... */

public TOUTPUT Invoke(TINPUT parameter) {
if (!cache.TryGetValue(parameter, out var result)) {
result = f(parameter);
cache[parameter] = result;
}
return result;
}
}
What’s your opinion about SystemVerilog? Can it be used as a higher level language compared to VHDL? Or it is still on same level?

> While working at Facebook, Winston sometimes dealt with imagery delivered through FTP servers or physical hard drives.

My company is a consumer of remote sensing data and we get basically all of our data from FTP. A more modern delivery mechanism would be very useful. If you can achieve data locality by downlinking data directly into AWS (groundstation) I could see that as a great benefit for customers who run their infrastructure in AWS. Especially as you get sparser data, data locality becomes a larger and larger issue.

> Today, buying commercial satellite imagery involves a back-and-forth with a salesperson in a sometimes months-long process, with high prices that exclude all but the biggest companies.

As a consumer of remote sensing data, my company has identified the data ordering process as one of our largest barriers to scaling our business. Our end goal is very similar to yours: we want our services to be available to anyone with a credit card and the full process should be automated. Currently, all remote sensing data has to be manually ordered which means we can never fully automate until our data providers automate.

Let me know if you have any questions on our use-cases for data providers. I have put a contact email in my bio.

Judge left dazed as DNA test shows he isn’t father of his 3 kids
Officially Wirecutter functions based on affiliate links and kickbacks and the reviewing staff isn't informed of this to maintain a separation. But this is a very weak defense. It's still a massive coincidence and obvious candidate for a conflict of interest when a product gets downgraded just as the kickback deal falls through.

Looking at the email exchanges I can't honestly think this is a coincidence. I've been shaken down before (unrelated to this topic) and that's exactly how it looked. My own experience going through Wirecutter's reviews kind of supports the idea that it's "pay to win".
I see these multiverse theories more as a philosophical idea than anything empirical. To explore the different variations of our own world can also be intersting to understand what's going on (e.g. what if $variable in the beginning of the universe would have been slightly altered).

But yeah more in the world of thoughts than anything else.
Polarity Puzzles – Soon to be released
If you're referring to the Everett multiverse (although the OP was not, so maybe you're not), then its status is not so different from that of the unobservable portion of our own universe.

That is, if we take the simplest known cosmological model consistent with our evidence, its equations predict space and matter outside our observable universe. That cosmological model is falsifiable in that it makes other predictions besides this one, many of which can be (and have been) tested, but this specific prediction cannot be directly tested.

Similarly, the equations of quantum mechanics predict multiple "worlds" (although I find this term unfortunate: the state of the "multiverse" is always just a single point in Hilbert space, and it only seems like there are multiple "worlds" when we imperfectly try to map that physical state onto the intuitive level of everyday experience). That specific prediction cannot be directly tested, but other predictions of the equations can be, and have been. There is essentially no dispute about the math. The dispute is whether to deny the reality of something which is right there in that math, akin to denying the reality of a universe beyond that which is observable.
