My main complaint about DeltaChat is that their threading model doesn't work with gmails threading model.

As a result when using it to message gmail friends their inbox is cluttered with a new thread for every single message I send. I haven't checked if it's due to the subject changing or if they don't properly set In-Reply-To/References, but its mildly annoying for my contacts.

Of course if they are properly setting In-Reply-To and References headers in the message, well then my complaint is really with gmail.
Does this draw into question whether there is such thing as a "nuclear field"?

Michael Cohen Testifies Before House Oversight Committee
While the idea is new to me - using friction in a windmill to heat your house - the practical use in Western Europe could be limited. Installing a 12 meter windmill in my backyard is not going to happen...
And then efficiency. A heatpump has a COP of around 4 or 5, so every 1 kW into the system results in 4 or 5 kW out. A heatpump uses electricity, which can be generated using a windmill, but also via solar panels. And a heatpump is relatively easy to link to your general central heating system.
Now if you'd want to link your water-brake windmill to the central heating I guess it would be a 'different biscuit'. And since the smaller systems generate 3.5 kW with a firm breeze, you need backup. Suppose you'd not use a water-brake but a generator and heatpump; wouldn't the overall system efficiency be better in that situation? Or at least more convenient if you add solar panels in case there's no wind?

The core problem with this is finding the land to fill. It's not as simple as any ole hole, the stuff is a low-grade contaminant that oozes nasties over decades. For the huge bulk of plastic waste that's a lot.

Better by far would be local recycling instead ; this is a fine thing for a government incentive as the (arbitrary, fickle) market incentive has gone away.

"Real" yogurt is culturally variable. Greek yogurt (or, at least, what's sold in the USA as "Greek yogurt"; I've never been to Greece) is specifically strained for thickening.

Electricity conversion: pretty darn efficient.

Conveying the heat from a brake to a building: not so much.
What redress do you think you have even if you "trust" someone? That 100 dollar widget you bought in cash didn't work? Well fuck you, see you in court. Now what? Are you going to take the store to court over 100 bucks? Pay with a card and your card company doesn't want to reverse charges? Same problem... I'd bet that per 5000 transactions, debit and credit cards have more fraud that the 'end user' has no remediation for than bitcoin does.

Sometimes, reinventing the wheel is exactly the point when the wheel has been engineered to favor the engineers.
I always find such opinions quite pigeonholed. Many third world countries do not have access to online banking or credit cards.

Immersive Linear Algebra (2016)
The article talks about this in the "Retarders and Mechanical Heat Pumps" section.
It's crazy how fast tuition has changed for flagship state universities. I went to my states flagship just over a decade ago and paid $4500 in tuition for the entire year that was fully covered by a state scholarship that's available to every in-state high school graduate with a certain GPA.

I just looked up what this costs now. $12,000 in yearly tuition and the same scholarship that used to cover all tuition now only covers $7500 (62%). I don't think I would have been able to afford that a decade ago without taking significantly more debt (and possibly private debt) than the small amount of FAFSA loans I did take.
The "general" category would be the correct place to report that. We'll review the report. If we can verify allegations we'll take appropriate steps, but at the very least even if we can't necessarily verify the allegations we'll notify the host of the website.
At $100/lb I think you could probbably do quite well doing it in small batches at home as a hobby.

As a french, I may order, at a restaurant, most of the plates listed here and I may eat at home one of those once a month.

As said previously, Foie Gras and Oysters are not everyday plates and some others are missing, but still I think it's pretty good.
So I think it's more "what local orders at restaurant" and not what they usually eat at home.
Too bad the editor can’t spell Hartmut Esslinger correctly.

Hartmut was prolific in the first decade or two of apple design. Steve contracted most design through Hartmut’s campbell office of Frog Design. Frog Design is responsible for the design dna of apple that Johnny Ivey built on and carried post 2003.
Electric motors/generators are typically much more than 20% efficient, the usual range is 75% to 95%. And you can use that energy for things besides heating on warm days.

EDIT: The overall wind turbine isn't that efficient, that's the efficiency of the conversion of the mechanical rotation to electric power. There's a good deal of loss between the wind itself and rotation to vortices and whatnot.

Electroneum CEO: why we launched a mobile phone
I run a Hard Cider company in OR.

We (the beverage industry/my company) are only in practice responsible for deposits. While we are required to take collections, no consumers really returns them to us. The return burden often falls on the retailers, who collect deposit directly from consumers.

When we sell product to a retail store. We collect a 10¢ deposit per can from them. The retailer then collects a 10¢ deposit from the customer.

My company gives all our collected deposits to a co-op (which is state run I believe) who handle the collection/recycling of the containers.

I interact with our bottle bill on a pretty small scale, but I believe that only changes my reporting frequency.

The article talks about this; it says the most efficient system is a mechanical heat pump (where the wind provides direct mechanical power to the compressor), but only for local generation, since heat transfer is much less efficient than electricity transfer.

Even for people who can afford it, this makes a difference for preserving low-traffic hobby sites you only mildly care about.

I have a couple of silly sites that I've run on App Engine for many years, using its generous free tier. If they were on Digital Ocean I'd have shut them down by now, as I eventually did for a Go search engine that I wasn't using much.
Fortunately for me my experience with HyperCard was quite different. We were encouraged --possibly even required?-- to make a game with it in middle school. That's how my very first ever game was made. Long since lost to time unless the floppy is sitting in a forgotten filing cabinet somewhere.

Of course, Amazon could lie, but now if Netflix has a reason to suspect wrongdoing, they could sue.

No. The "nuclear field" is just a term for the composite field resulting from the constituent particles of the nucleus (the quarks and gluons) and their interaction. For there to be no "nuclear field" there would have to be no nucleus.

Well, that's not entirely correct, because particle fields permeate all of space. To grossly simplify, there's something happening in those fields in a nucleus. The various particle fields are vibrating and interacting. "Nuclear field" is just shorthand for this interaction that is the result of the presence of the particles of the nucleus.

The result described in this article just rules out the nuclear field as being responsible for the EMC effect.

China's Import Ban Broke Plastic Recycling. Here's How to Fix It

https://news.nationalgeographic.com/2018/06/china-plastic-re...
Why would you say that there's no legal means of redress? If someone steals my cryptocurrency, then I can still have law enforcement track them down and attempt to recover the funds.

This is not dissimilar to how cash works -- if someone takes my cash, by fraud, by theft, or in legitimate exchange for goods or services, that's it. They can now spend it however they want. Cash itself is a trustless system in the same sense. Where there is trust it's largely a matter of preventing forgery; which is not dissimilar to the idea of preventing double-spends.

But until Bitcoin there was no real way to do cash-like transactions electronically.

In other words, the utility of Bitcoin is well-established; humans have been using cash for a very long time. The implementation is novel. I don't speak here to the general "blockchain" concept, which has become so nebulous that I don't feel it's worth making general statements about.
when participants don’t trust each other, they delegate to a third party they both trust: a bank, a notary, an external accountant, etc.

Blockchain provides nothing, and people end up building replicas if real-world trust systems around it (even silk road had a reputation system not built on blockchains)
I don't know how that happened but now it won't let me update the URL now.
Yeah but here the action would be to make a false publication, which as discussed higher up the courts have been reluctant to force people to do.
Just as I was going to say that...

Although I think that plot aside, Metropolis has far more artistic merit than Avatar (or anything Cameron ever made, makes, or will make).
Consider: it might be cheaper in total long-term ROI to dispose of things in landfill now, and then let people a hundred years from now dig them back up if they have need for the materials then, than to recycle those things right now. And by “cheaper”, I mean for the entire economy that includes both us and the hypothetical future people digging those things up! Our recycling now might have lower ROI (higher costs, less reclamation efficiency) than their digging-up + recycling would! (This is actually a thing in archaeology: frequently sites that are hard to dig up will be left to future archaeologists who—it is assumed—will be able to reclaim them more cheaply and effectively than we can today.)

It’s sort of like the “bargain” of cryptocurrencies: what promotes long-term GDP growth more, bank fees or massive electricity use? Crypto miners are hurting the environment right now; but they pay for their own externalities. Banks impose fees that lower net productivity in a way that might mean that the companies/technologies that we need to reach sustainability take longer to come into existence. So will we be in a better place with 100 years of crypto mining + 100 years of an economy [including green industry] that was spurred on no bank fees; or vice versa? The question doesn’t have an immediate, intuitive answer.

A stupid but weirdly-precise analogy: when playing an RTS like Starcraft, anything that slows down your “economy” (mineral mining) prevents you from “teching up” as quickly as your opponent. In humanity’s case, our opponent is Malthusian resource starvation (in the small—of individual resources) and habitat loss from climate change. Anything that slows down our economy from “teching up” to face these problems, for a reward of merely moving around in time our ability to use our resources (rather than decreasing permanent losses/increasing permanent gains of resources), isn’t really worth it, if we’re “racing the clock.” (That’s a big, hotly-debated “if”, of course.)
My family came to the US like 20 years ago and I can't remember a day when we didn't have yogurt. Whenever my family goes on a long trip, we have to do two things: get a neighbor to water the houseplants, and get a yogurt culture when we come back. In South India, it's traditionally eaten with rice as the last course of a proper meal. It's the perfect antidote to hot curries and pickles that come in the main part of the meal, so a meal isn't complete without it.

Young children usually start off eating solid food with a mix of rice and yogurt.

In rural areas, families make yogurt with their own cows and buffaloes and might pick a particular one for yogurt because taste varies between milk produced by different animals.

Going to relatives' places you'd notice two differences in their cooking: the way they made their chai (brand of tea, how much sugar, cardamom or not) and the texture and tanginess of their yogurt.
Process people will take their sweet time to turn this into a marketable fab product.

I'd say that it can come to market quicker as a packaging house product: they grow resonator dies with BAW separately, dice them, and put into existing RF SoC packages.
only the first revision (and the A/A+ until the 3A+ came out) had 256Mb. It was soon upgraded to 512 as one of the first design changes (before moving to the "plus" form factor with 40 pin GPIO header) the early A's even had 128Mb but they are a rare thing as the original A was not promoted much before the first upgrade cycle.
And don't discard the whey (the drained remains).

It is protein rich and goes very well substituting water in pie dough, buttermilk in pancakes or added to waffles or dough. You can use it also for American biscuits.
The thing about externalities is: somebody pays, it's just not the person who caused them. Redirecting that cost back to the source would be a good thing. There would then be incentives to do the most efficient thing instead of the most wasteful thing. This would actually make everybody richer.

How much of our wealth is being wasted this way? I'm guessing that it's a lot.
40% of Smart Homes at Risk to Hackers
We need more public education on the Reduce and Reuse portions of the 3 Rs that only have Recycle as a last resort. We’re getting further away from those in the name of convenience, with things like meal delivery like Blue Apron. Start small: dont use those bags for produce, bring reusable containers to eat out for bringing home leftovers, use a reusable water bottle, buy as much in bulk as you can (with reusable containers).

Yes, he is hard to watch and they have useful information in their reviews. It's hard.
I really think this is one place where standards could be transformative for society.

Not only the obvious benefits, but standardized bottle shapes allow manufacturers of, say, refrigerators and furniture to tailor their wine racks/dairy drawers/etc to fit the standard product packages perfectly. This gets you more room in your fridge, and your living room... And then places like Amazon can tailor their boxes to perfectly fit the products too.

I noticed this when I went into a Japanese bookstore and saw that all the books were the same shape, even from different publishers, and the bookshelves were perfectly sized to fit them.

I don't know what kind of power brought that about (small homes?), but compared to a North American bookstore where it seems every book is fighting to be a different size and shape, to stick out from the shelf and stand taller than its neighbours.
> In October, The Information reported that Bird was spending $551 per scooter with a goal of reducing that cost to $360.

The full article is gated, but I'd be interested to know where that figure came from. It is possible for a private individual to buy the same scooter tax and import duty free for the lower of those two prices. I would hope that multimillion dollar companies like Lime and Bird would be able to secure better pricing than that.
Author here. Slow behavior while searching through a large number of files is a known issue at this moment. I will definitely try to reduce it by some extent by immediately streaming to STDOUT (or to a non-TTY device if TTY is not STDOUT). Right now, the results are accumulated, filtered and then printed in one go.
Probably that's the version that introduced the poll API. They developed it on Win10, then noticed oh it should work on Vista. Tested it [maybe] and put it in the changelog. (And probably they have nginxplus customers that need Vista support?)
My experience is that if you have to maintain your own stack (which you'd need to in order to recursively walk directories) its faster to use the builtin stack than to implement your own.

Further, it seems that this would IO-bound not CPU-bound so whatever small overhead exists in recursion vs iteration will not be noticeable.

I think the difference is rather that `fd` uses threads and `ff` does not.
It's not an exploit. It's a vulnerability baked in the wallet app source code. There's a difference.

Of course you can stiff the legal system. But you can only stiff it so far. I Googled "Ethereum steal" and the top three results have figures in the millions, through something as straightforward as a 51% attack. No court system can simultaneously claim to be fair and just and legitimate, and let slide a $1.1M USD theft. And in such situations, other people usually have a bone to pick with said thief too, bolstering resources on your side.

If a cryptocurrency scales and somebody pulls off a Madoff-level theft (>$64B USD), could you guarantee some amount of clawbacks by technology alone? I wouldn't bet on it.

Does this mean we need to update Greenspun's 10th rule "Any sufficiently complicated C or Fortran program contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp." to say "Any sufficiently complicated development environment contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of PHP?.
Okay, here's the thing: If you have plants with more or less CO2 under otherwise the same conditions you'll have more growth in the plants.

However that's not how the planet works. If you put more CO2 in the atmosphere you'll have for example rising sealevels and larger deserts (and probably more effects that diminish food production). You can't just pick a single effect of increased CO2 in isolation. (Except of course that's what the CO2 coalition does, because they chose to believe fairytales instead of science on climate change.)

This is just the obvious flaw in that argument. If you want the details and all the science there's a chapter on food security in the IPCC report:

Hey HN,
Just out of curiosity, which changes did you make and why?

For me, I've been using a smaller keyboard (60%) and hardly use the mouse so I don't need to move a great distance with my arms.

I try to keep my desk height and monitor height OK as well.

More for preventation rather than for 'curing' anything. Though I sometimes ponder wether or not I should also just get an ergonomic mouse for the times that I do use it. :)
