The research on this is still at early stages and hardly definitive, but it does seem to indicate slight preference for eTRF (early time-restricted feeding)

https://blog.mycircadianclock.org/early-time-restricted-feed...

> Compared to the control 12-hour schedule, eTRF decreased fasting insulin, as well as the overall level of insulin during an oral glucose tolerance test. This test demonstrated that eTRF led to improvements in both insulin sensitivity and β-cell responsiveness, the latter being an important indicator of pancreatic function. The other notable benefit observed with the eTRF schedule was a significant decline in systolic and diastolic blood pressure.

You mean, if the United States falls from "number one in innovation" to "number two in innovation", whatever those numbers are even supposed to mean? The US, with a population of 330 million, is not going to just fall off the face of the Earth. We've got plenty of talent and resources.

Actually, the US is currently engaged in genocide... of its own population, sadly. Or maybe we should call it suicide.

This material is completely unsuited for making shoe soles or elbow pads; it's a two-inch-thick plate of aluminum foam with half-inch ceramic spheres embedded in it. Around that they welded steel plates to give it a uniform surface.

It'd make a very heavy but uncuttable door, but you can't make hinges or locks out of it. It would be a good material to make safes out of; those already have thick walls of composite materials designed to blunt drill bits.
Most of them are from engineering fields, not from computer science. Their interest is designing and implementing engineering models rather than programming itself. So they are not as adventurous as computer science guys in investing new programming tools (languages).

Also, I am pretty sure more than 90% of them have never learned functional programming or related computational theories, even in schools.
I've managed to keep my bike locked up outside OVERNIGHT in San Francisco (Washington & Polk St.) for a year now. How I did it? The short version: one very good lock (Viro Euromonolith + Peewag security chain, $175), a second good lock (kryptonite, $90), and an okay lock (Abus, to keep them from stealing the basket, $60).

I've also had 3 bikes stolen, the rear wheel stolen, the basket stolen, the front brake stolen, the seat stolen, but now with all the locks there is much less stealing.
Elon Musk says Neuralink will stream music straight into your brain
The article is spot on. As humans it is incredibly difficult to avoid being committed to your decision, a big problem for 'strong opinions, weakly held'. I think Elon's advice is much better and I try to exercise it regularly: "Assume you are wrong. Your goal is to be less wrong."
>Twitter is open, a private email server is not.

In what way is Twitter "open"? Can I FOIA a government official's DM's? I don't see that as likely.

From my standpoint, Clinton's private server is equivalent to Twitter (albeit likely less well-maintained from a security perspective).

To my mind, it's wholly unacceptable for the US government to maintain secret communication platforms outside the reach of FOIA. Working to keep communications off-the-record and out of the public's hands is a betrayal of the public trust.
That's what you think.

What you're looking at is the probability of the US Capitol being in a particular place. It's a common misconception that fog makes things look blurry, but you're seeing the effect of the average probability of it being there at all, given the many possibilities in alternate time tracks. It is blurry. Never mind what might be going on inside.

People who wander into fog often come out into a different world, but generally their memories adjust...not always though.
Well, I certainly hope they are, but I doubt that they are as institutionalized as you seem to suggest.

I also think that using "Marxism" for a democratic movement and ideas is done to intentionally associate them with the authoritarian regimes of the 20th century.

So essentially, no, they do not have "all my emails".

You just said previously the exact opposite! That they can't query Google, but they have the data themselves.

> "Is that a meaningful difference, in terms of privacy?"

Yes, because it means Google are aware of what data they are being requested, and what they are sending in return.

The transparency reports for these companies show that the total number of requests is in the region of 10k/year - a lot in some senses, but nowhere near the level of surveillance many people seem to believe.

It looks like the best mix of abstractions like first-class Result, Option, Future, and Trait with some of the best performance.

In Go, I write twice as much code for code that's slower than Rust. I can't even reuse code without copy and paste. Python and Clojure don't even have Rust features. Python doesn't even have .map. Go is barely statically-typed (bet you're gonna use interface{} implementing this too), Python and Clojure aren't at all -- so that's also going to be a source of gut-reaction "whoa this must be complex".

The code looks very pleasing to me.
Agreed. There's very little evidence to support the claims about what is discussed here is what made Stripe successful. Intuitively many of the claims seem true but where is the data?

Weak opinion: I cannot conclude anything about why my car won't start.

Strong opinion: I think my battery is dead and that's why my car won't start.

Strongly held: I tested the battery and voltage and current are within good thresholds. I still believe what I believed before.

Weakly held: I tested the battery and voltage and current are within good thresholds. I have adjusted my belief about what I believed before.

WOSH: I cannot conclude anything about why my car won't start. You've tested my battery as dead. I still cannot conclude anything about why my car won't start.

WOWH: I cannot conclude anything about why my car won't start. You've tested my battery as dead. It could be the battery, maybe. Hard to say.

SOSH: I think my battery is dead and that's why my car won't start. You've tested my battery as functioning fine. It's definitely the battery, though.

SOWH: I think my battery is dead and that's why my car won't start. You've tested my battery as functioning fine. The reason why my car won't start is not my battery; I think it won't start because my starter motor is broken.

Waveshare e-ink displays are good for small DIY projects, but not more than that due to questionable reliability over long term use, but I'm glad they exist and they have good documentation.

Also, since the refresh rates are limited it's not like we can build ourselves a nice external large e-ink display for our reading pleasure and for the sake of our eyes.

There's a need gap for 'Affordable E-Ink large external displays'[1], last time we discussed about it here it was pointed out that the likely reason for we not having such displays are due to IP.

> ...make a tentative forecast based on the information available, and then systematically tear it apart, using the insights gained to guide my search for further indicators and information...

This is literally the scientific method. Come up with a falsifiable premise, then attempt to falsify it. Arguing that science is hard is pretty irrelevant. Most of the failings present in this article are really just evidence of not doing the second half. You should be looking for evidence that you're wrong, not evidence that you're right.

This is later borne out by the proposal of adding confidence intervals and dates by which assumptions should be robust against being disproven. You'll find this type of language on experimental design in lots of scientific fields.

This article is about someone's journey to rediscover the thing their source already knew (using scientific rigor can take a hypothesis into a theorem, and gradually bring you nearer an understanding of the underlying truth), and then call it something else because the original distillation of a theory into a soundbyte flew past them.

> The cellular structure showed significant deformability, exceeding 20% of engineering strain as expected from previous studies of cellular metals

This only talks about the cellular structure, not the overall material structure, but would this mean that the material would start to deform under a heavier strain? Does that mean it would make sense to not use this material alone, but rather with other materials to make a strong product, e.g. a bike lock with this material on the outside of a thin but rigid pure metal core?
This is using GOES imagery for "live" North America which uses multispectral IR for night [1] but True Color for day. Once you pass a certain zoom level, it switches to historical imagery from Microsoft.

Side note, you can receive GOES images straight from the satellite yourself with a $30 SDR, a $30 LNA, and an antenna made from scrap (or ~$100 if you're not handy).

Hi -- just wanted to say that there's a lot of armchair theorizing in this particular thread of discussion. I'm directly involved in building the product and the most succinct way I would personally summarize it is that the service (not product) is a subscription. Customers are not only paying for value derived from the current product but from the near-constant (~24/6) evolution and development of it (thousands of engineers spread across many timezones), and 24/7 monitoring of it. Or another way to think of it... what's Mercedes' ROI for improving their luxury cars? It's already a best-of-breed luxury car -- they could just do nothing, right?
Even without a pre-cut rack, its pretty common that whatever you've locked up to (sign post, bike rack, parking meter, handrail, etc) is a lower grade of steel than the ultra-hard stuff on the shackle of a good bike lock or chain anyways. No need to pre-cut that cheap galvanized steel sign post if you don't want to, a thief would have no problem getting through it quickly if something attractive was locked up.

I'll use about $100 worth of u-locks to lock up my not-super-visually-impressive $250 spare parts city errand bike as long as overnight (and this is in NYC).

But I think the strike point where spending more on heavier/fancier locks to secure a more valuable bike just stops making sense is right about at the price point I'm already at, most nicer bikes are simply too nice to leave unattended on city streets in the US or anywhere else where bike theft is a concern. Someone with a good set of pocket tools could rip $500 worth of parts off a well-locked frameset and wheels in 20 mins without making any noise... and I don't think a non-cuttable material helps that scenario, even if it does make very secure locks attainability light.

(Could be a really big deal for bike touring folks though, who often ride out with a cheap cable lock at best because anything better is too heavy to carry for days/weeks)
We are a community of craftspeople and engineers. What something is built with is something 99% of us want to know. Usually what something is built with and how it was built is frankly the only interesting thing to talk about.

I don't want a cli habit tracker, but I'm still here looking at how they built it, bikeshedding with my commiserators.

You may be more interested in Product Hunt. Not sure I understand your complaint, though. Makes me think that you would leave it off of your HN submission in some weird masturbatory idea of modesty. "Well, so what was it built with?" "Oh, I couldn't say ;)"
>ceramic spheres encased in a cellular aluminum structure

sounds like the modern "ceramic in a metal matrix" tank armor:

https://en.wikipedia.org/wiki/Chobham_armour

"The (pulverised) ceramic also strongly abrades any penetrator. Against lighter projectiles the hardness of the tiles causes a "shatter gap" effect: a higher velocity will, within a certain velocity range (the "gap"), not lead to a deeper penetration but destroy the projectile itself instead."

From the article on the material

"Water jets were also found to be ineffective because the curved surfaces of the ceramic spheres widen the jet, which substantially reduces its speed and weakens its cutting capacity."

Not just water jet, the ceramic/metal armor withstands even shaped charge jet :

"Because the ceramic is so brittle the entrance channel of a shaped charge jet is not smooth—as it would be when penetrating a metal—but ragged, causing extreme asymmetric pressures which disturb the geometry of the jet, on which its penetrative capabilities are critically dependent as its mass is relatively low. This initiates a vicious circle as the disturbed jet causes still greater irregularities in the ceramic, until in the end it is defeated. The newer composites, though tougher, optimise this effect as tiles made with them have a layered internal structure conducive to it, causing "crack deflection".[2] This mechanism—using the jet's own energy against it—has caused the effects of Chobham to be compared to those of reactive armour."
My guess is that the hacksaw wouldn't work particularly well, but the bolt cutters or anything else that just exerts a strong, steady force without much motion should work. At that point, it shouldn't be any stronger than just regular aluminium.
Look, I know that the idea of being customer focused might seem trite, but I wanted to focus on one thing: it's the little things.

"What actually differentiates stripe from the rest of the bunch though? It’s the little things.Stripe obsesses over creating a seamless CX. Small annoyances in applications compound. A user might not churn immediately because you have a bunch of unoptimized functionality or crappy UX, but it’s a recipe to create a grumpy user. And grumpy users aren’t loyal users."

This is an idea I've been turning over in my head a bunch recently: the compounding effects of delighting your users. That cumulative innovation that comes from building for your customers....I sometimes get asked "what's the killer idea behind [company X]". But there isn't one big thing. There are many, many small things built on having a relentlessly customer-back attitude. You can't just copy the "idea", you have to copy the way of working and thinking. That's a lot harder.

Let's take Brex as another example. It's the segmentation, UX, marketing, rewards, underwriting, etc. It's each of those things broken up into a hundred subcomponents and iterated on. It's an entire ethos and operating model. That's cumulative innovation...not a single idea.
Like all metal items, this is trivial to recycle by melting it.
Maybe this is the key point here. We feel our system is less evil because we think we control it. While the evil CPP has no accountability to the population. I think the reality is both systems are really not under the control of the citizens (not really anyways. Call it 0% control in China and 10% in the US), but the illusion of control in the west gives a sense of comfort.
That’s pretty cool. can it be cut with bolt cutters or such?

The craftsmanship is there, but 95% of people can’t afford it.

It starts all the way from the fact that suppose you and your competitor are looking to purchase a parcel of land to develop a community. You make a nice plan that retains nice old growth trees, gives adequate space for eaves, design better than minimum standards drainage, insulation materials, etc.

Your competitor draws up plans and cuts all of those niceties out, and saves a few million dollars on costs. Now the competitor can offer to pay a few million more for the same parcel of land.

Guess who gets to develop it?
Is this sort of like the weapon the guy in No Country For Old Men was using?
Yes, if you already have k8s cluster that you don't manage, and you can use for your Spark, I would like to say you have Spark serverless environment.

IMO, where actual spark executor runs (either on lambda or k8s, or somewhere else) doesn't much matter to say it is serverless or not, while user can access the cluster, without managing them.

In our case, we build Spark Serverless service through

- Fully managed Kubernetes cluster
- Isolation between Spark instances (network, storage access, etc)
- A dedicated Kubernetes node (VM) allocation for a executor, to provide container level security and better performance
- Secure tunneling between remote Driver and executors for interactive mode (spark client deploy mode)
- Various optimizations
The American right are just using those excuses to deny entry to people from other ethnicities. If you satisfy those conditions they will create other reasons why we should deny entry to immigrants.
A lot of commenters are suffering from the bias we suffer from every time we discuss issues of the past: the "old homes" are good in party because they have passed the test of generations. The bad designs from those generations have largely been torn down. Just because something is old does not make it good.

It is another question entirely why we continue to fall for the same poor designs.

What construction equipment could possibly need an indestructible fence surrounding it?? Most construction sites have chain link or orange plastic fences, and they’re not to prevent theft. You hire security or insure the equipment against theft to protect against theft.

Anyone that owns heavy equipment carries insurance covering damage, theft, and liability. Otherwise it’s rented and Sunbelt or whoever is on the hook to replace it.

Safe and vaults, sure.

I think you’re right! I haven’t explored these systems enough to comment with certainty.

I think Stan and PyMC3 both focus on optimized implementations of Hamiltonian Monte Carlo - a Markov chain Monte Carlo algorithm which requires that you express models with target variables whose log probability densities are differentiable with respect to their sample spaces. I think Stan provides other algorithms as well, and possibly also PyMC3 but I know that these systems are known for their implementations of HMC (similar to NumPyro, which has a highly optimized version of HMC).

This is certainly not all probabilistic programs - but many popular models do tend to fall in this category (where you can use HMC for inference). In both cases, I’m also unsure if these systems are “universal” in the sense that you can express any stochastic computable function which halts with probability 1. Similar to Turing completeness, if the system does not allow you to express control flow with runtime bounds, or disallows stochastic bounds - it’s not Turing universal. This is not typically a bad thing, because most classical models don’t require this feature, but it does tend to separate frameworks for PP.

As a shameless plug, my own library doesn’t rely on AST meta programming (e.g macros) but instead relies upon dynamic compiler interception - which is metaprogramming of a different sort.

PS for another PP system which doesn’t rely on metaprogramming, you could explore Probabilistic C: http://proceedings.mlr.press/v32/paige14.pdf
Too many restrictions, path to permanent residency is way too long.
I have the 2.7” 3 color (b) hat, and it is very slow with stock code. As far as I know, and from the looks of the Python code, 2 full buffers are transferred for the colors and then a process of wave stimulating the fluids into arrangement are how it works, very conservatively and slow. There has been work done to the firmware to allow partial updates fast enough for animation, but they should be used sparingly to avoid temporary or permanent burn-in, they say.
