But I did.

The same amount will be worth less in the future! That's really all there is to it. A certain amount of money is not value, money is a number that has a value associated with it, that value will continuously change depending on what you can do with it.

Inflation (deflation) simply reflect the change in value for doing something today versus tomorrow. When the economy works well you have inflation, when the economy works badly it becomes deflation.
So this work seems to be about demonstrating the engineering aspects of molecular solar thermal energy storage. They put all this work into describing the microfluidic chip they use, pumps, and other details. They also use an azobenzene derivative for energy storage, which was probably chosen because the synthesis of it was trivial(2 steps) meaning it was easy for them to make enough for the test set up. Azobenzene has been considered for solar thermal energy storage since about 1976, and I suspect even earlier[0]. But there are better molecules out there. In this paper here[1] the same authors develop a molecule based around norbornadiene that has an estimated energy storage efficiency of 3.8%, an energy density of 0.48 MJ/kg, and a half life of 10 months. They even have a molecule with a half life of 18 years in one of their tables. So this publication is probably more in line with the storing solar power for decades from the headline.

I'm sure that happens, but it didn't in my cohort. If you whip a dog for a while, it'll fight. Whip it for long enough, though, and it will just lay down helpless. That's what I saw.
I really do think automation and the logical efficiences of getting a robot to transport produce from 200 miles away vs 20000 miles away will fix this problem.

Farms will come back, they will just be run by corporations instead.
And it'd be safer if more people were subsidized to buy them. Safety in numbers.

I'm not from Germany, but I did notice that they changed the color for the German site. My comparison is to the American site.
I don't know the numbers, but a Tesla is specifically attractive for a business owner. The subsidy is absurd.

The government has acknowledged this now, and it will tapered down / abolished. Not sure.
Those machines are available here in the US. I considered buying one. While not having to switch clothes was appealing, the low capacities and long cycle times felt like it cancelled out that advantage. The lackluster reviews I read from those who had made the switch were probably the biggest reason why I didn't do so myself.

As I understand, our laundry habits are a bit different than much of the world. We tend to wash everything after one use and clotheslines are few and far between.

Also, our energy prices are cheap, so the pay-off curve for the efficiency gain of such a machine is long.

They'll probably get more popular as family sizes continue to shrink, and people continue migrating back to cities.
> Libra is supposed to be a decentralized blockchain payment system, similar to Bitcoin

There's a very big difference between Libra and Bitcoin. In Bitcoin miners can come and go as they please, and they don't have to be known or trusted. Bitcoin's innovation with POW was to make this possible at all.

In Libra the consensus nodes are known, making POW unnecessary.
Only one person on the entire planet has demonstrated the ability to write security hole-free software, Daniel J. Bernstein, and it's unlikely that Facebook would be able to hire him and then get him to rewrite their entire stack.

You don't feel bad because of their word choice? That reflects poorly on someone, and it's not them.

Hi HN,

We're Jake, Scott, and Akshay – the founders of walrus.ai[1]. Throughout the process of building our previous startup, we learned first-hand how important automated test coverage is to any product. At the same time, it was such a pain to implement. As we spoke to our customers, we learned that they hated writing these tests too.

So we decided to build a product that drastically simplifies how we write end-to-end tests – and that's walrus.ai.

Features:

- Easy — write tests in plain english
- Fast — get results in 5 minutes
- Developer-first — integrates directly with your CI/CD through an API call
- Reliable — human-verified results

You can try us for free, and we'd appreciate any feedback! scott@walrus.ai

Well, based on a 2017 version of their site in archive.org, their 'pink' is rgb(214, 0, 109) while T-Mobile's current pink is rgb(226, 0, 116). Not the same, but as a graphic designer, I think they'd be visually indistinguishable for most people unless comparing bordering swatches.

But fuck T-Mobile though. Magenta is a primary color in most types of print. That they can somehow stop other people from using it is bullshit.
You can find the resolution online. It depends on whether it's a 13" or 15" model. It is less than 4k, but has a higher DPI then 4k desktop screens. The only thing which gets as sharp are the 5k 27" screens - that's likely why Apple decided to make them.
Both trademark and copyright laws need reforms, and fast. This is getting ridiculous, they're not even in the same industry.
My comment had nothing to do with imaginary internet points. You just said being wasteful was part of the definition of a blockchain which is a common argument people like to make when promoting the false idea that blockchains are inherently bad for the environment. It felt important to point out that there are non-wasteful ways of accomplishing the same thing as PoW.

> Does anything prevent having one code for residential buildings over a certain size, and another for smaller buildings?

The building codes aren't the way they are because you need different rules for smaller buildings. It's because existing residents don't want smaller buildings. If you can build smaller buildings then people will, and then you have a bunch of new students in your school district whose education is paid for from local property taxes, only their parents aren't paying a proportionate share because they have a smaller house with a lower property value. Which means the existing residents would have to make up the difference, which they don't want to do, so they have the building code prohibit building smaller homes.

It's basically regulatory capture by existing homeowners of larger homes.
Trademarks are granted in specific categories for instance there are at least three large companies using the name delta, airline, electronics, and faucet company.

I was beaten up repeatedly in school. The school did nothing to stop it. This is during 8th and 9th grade. I was also stabbed with some kind of homemade knife, a pen with a nail in the tip. It hurt but the injury wasn't serious. I finally decided that I'd rather go down fighting, and I started beating up my bullies, or at least fighting back. I found that mostly these kinds of people like easy targets, so they started leaving me alone. I haven't been in school for many years, this is in the 90's. I don't know what it's like anymore but I do know there's been an effort to bring more attention to bullying.
You mean like Apple did with the lowercase "I"?

While that's unfortunate, I'm wondering how long these fleets keep cars before they're sold? It seems like this would improve availability of plug-in hybrids on the used car market.
I'm currently reading Fall; or, Dodge in Hell as my first Neal Stephenson book. I will say the plot summary doesn't do it justice. Regarding the setting the in mid-point of the story, with the split between reality-based social media feed individuals and fear/meme-based feed populations - I went from an initial reaction of "that could never happen" to a feeling of a realization "that is already happening". Especially as I was listening to the audiobook while on a long drive through a semi-rural part of the state to visit relatives who would definitely fall into the latter category.

Sure, the number one requirement is to get the job done. But, nobody that takes pride in their work is going to be satisfied with fat, slow code. Efficient code is a thing of beauty that takes time to craft. Unfortunately, our desire to make beautiful things gets crushed under the constant race to production of the next feature.
I was there. By the time the dotcom bubble burst, the Internet was already everywhere, having steadily grown as a household technology since first introduced to the general populace just a few years earlier.

The dotcom bubble was then precisely a symptom of the Internet's runaway success: Everyone wanted to use it, massive amounts of money were being made with it, and so everyone thought they could make money with it as well. As a result, even the stupidest ideas got funding.

When the bubble burst, it caused a significant economical upset. It did not have any really noticeable effect on the Internet itself, its usage, and the availability of most of the services that were actually in use. I don't think anybody remembers a time where Internet usage "dipped" from its massive momentum since the mid-90s, because the dip was largely economic.
You don't have to fix the greed, you have to add oversight and accountability with things like mandatory reporting that make it not worth doing these activities on any profitable scale.
Havinga bunch of US corporations run the global payment system won't solve this problem.
>But you can't "fix" greed. Even punishing greed doesn't make people less greedy. That's a bit like thinking that the war on drugs will make people want drugs less

Or that punishing robbing banks makes people do it less?
Outdoor gear is an especially good way to shift your purchasing from online to supporting local retailers, specifically because their pricing is very competitive. Backcountry.com pricing isn't saving me any money vs my local gear stores.

The only problem is actually finding a good outdoor gear store - i'm lucky enough to live in a mountain resort town, so my options are pretty good, but many places simply don't have a local shop.
Get the 4k, set scaling to 200%, and be amazed on how much easier things are to read on it. That will come with a loss in screen estate, but I rarely need it. For applications where you want more text you can still decrease the font size and have far more readable text than on a screen with lower resolution.

Generally, in mathematical publishing, when someone refers to a book by the author's name, the title is (essentially) the topic.

Without clicking the link, I'd bet dollars to donuts the book is titled "Hinged Dissections", "Hinged Dissections: A Pivotal Analysis", "Hinged Dissections: Swing Sets", etc.

edit: it's "Hinged Dissections: Swinging and Twisting". I prefer "A Pivotal Analysis".
Wouldn’t the socialist meccas be places like the Nordic countries?

Strong social safety nets and workers rights, freedom of expression and religion, etc?

I don’t think the people who identify as woke are in favor of top down party rule which stamps out dissent and free speech and puts Muslims in organ harvesting concentration camps.

I think they’re against unfettered capitalism where wealth accrues at the top while workers rights, infrastructure, and education crumble or are taken over by private enterprises which skyrocket costs for essentials at the expense of the citizens.

Although, I wouldn’t be surprised if there was a lot of black/white thinking out there in these cloisters and communities where anything capitalist is equivalent to bad, but people who can’t acknowledge that the world’s a particularly messy place full of ambiguities, well, they generally don’t make good leaders as far as I can tell.

I searched for alternatives and still went with ubiquiti. They exist in an interesting zone of technically competent, reasonably priced, and able to function without internet access. It is hard to find a competitor that hits all those marks.
The AWS and Azure sales people are giddy with joy right now. If Google does not strongly repudiate the protest, Google Cloud is saying that Defense companies, Oil and gas companies, and Car companies (except Tesla) are unwelcome on Google Cloud.

If you look at the largest companies by revenue

https://en.m.wikipedia.org/wiki/List_of_largest_companies_by...

these types of companies make up a large proportion.

In addition, other companies such as Big Pharma, Health Insurance and Big Banks which are unpopular with the left would also be worried about when they would be the focus of a new protest.
According to their website the Google Home mini, the one with the cloth mesh top, is surprisingly one of the most resilient to this type of attack, being limited to about 20m in ideal conditions(1).

It's also one of the cheapest voice controlled home assistant devices, being given away by Spotify, Google and others on special promotions.

I remember somebody who hassled me often at high school met me by chance in the pub in later years. I told them what a wanker they were to me at school and this made them agitated. When they asked. What they could do to make amends they didn’t like my verbal response. So suddenly they got aggressive and the aggro started right there. Some never change when they’re mask slips.

Formal methods are a large set of methods that allow you to analyze a program in ways that can verify it satisfies certain (correctness) properties. Most formal methods don't generate tests (although some do), but the term "compile-time" is not often used, as most formal methods are not part of the compiler.

There is some overlap between PLT and formal methods, as that some concepts studied in PLT -- most notably type systems -- can be used for formal verification, but the main thrust of formal methods uses other techniques. Both disciplines heavily rely on formal logic.
I don't disagree with you, but I'll note that the non-dischargeable terms of medical and student loan debt in the USA essentially do that already, with the added caveat of not even incentivizing the note holder to get the borrower on their feet. Is this no better than that? I think it's moving in the right direction. It's capped, and while there's still the potential structural issue of middleman taking an unfairly sized cut, the incentive structure of "we don't make money unless our education helps you do so" seems like an order of magnitude better than the alternative.

It wasn't ad hominem, it was largely in jest as most of the people I've encountered who don't like Michael Lewis are HFTs who didn't like Flash Boys. If you are worried about substantial discussion here, perhaps you could start by detailing why you disagree with Michael Lewis, rather than dismiss him outright with generic, detail-devoid dismissals that he doesn't know anything, as opposed to yourself who does "know what you're talking about".
People will NEVER support a government that asks them to move. That's the whole reason these towns exist.

Look at China - they literally forcibly relocate people at economic gunpoint(their jobs will be moved and their homes will no longer exist by this date, their choice of what to do) and somethings actual gunpoint.

That comes with a whole slew of societal issues. The elderly simple cannot adjust to different lifestyles, they freak out.
I use mine to check the weather every morning and frequently listen to the news feature. As well as music during the day sometimes. I love them :) I think other people are just obtuse or paranoid about surveillance.

Israeli Arms Export are aligned to the US ever since the Phalcon deal with China that the US overruled.

The NSO needs to get an export permit for every sale, if you think the US doesn’t have oversight over this you are fooling yourself.

Congrats on the launch!

Metrics monitoring is hugely useful for figuring out what's going wrong (or right...) and where - especially when you can slice and dice by dimensions/tags. Microsoft (where I work) uses lots of metrics internally, for every sevice. It's nice to see M3/Chronosphere making this kind of thing more affordable and widely accessible.

It used to be society wanted people to have an education and that people with degrees would get higher paying jobs which resulted in a net benefit to society through higher taxes.

Now education is just looked at as a way to in debt young people for the rest of their lives. Because 1M people default on their student loans every year and the bubble is on the verge of popping, the parasites are looking to own 10% of every dollar you make to finance your education.

The problem isn't that an API doesn't exist to automatically debit 10% from the people you own, the problem is an education doesn't get you a job anymore, much less a high paying job.

Instead of owning peoples labor via API, why not consider the 1 Presidential candidate who is campaigning to forgive all existing student debt and make college free moving forward by god forbid...taxing the same banks the taxpayers bailed out from bankruptcy just 10 years ago.
If your phone has a mic, it's most likely also listening. Most new phones have the same technology as the smart speakers. And even if it doesn't have the feature, it's can still be compromised to be listening.
That's correct. And I don't believe maximizing your profit should always go before thinking about what you do is ethical.
Grocery Stores closing really is happening, and really is a problem. And it's part of what's killing towns - if only because attracting new folk without one is hard.

We live in John Day, Or (pop 1700)(County pop 7200, area: about 2x Delaware), which we chose partially because of it's supermarket. The next closest supermarket is 90min away. (Walmart: 2h). Not having to commute hours for groceries is a big deal, as is being able to get vegetables of season - and in the rural west these things not a given.

When looking to relocate from Seattle to rural town in the west with hospital (wife's a doc) and broadband (for me), it soon became obvious that the quality of the food available was going to be the next most important thing on the list (and much harder than broadband). Too many places we looked had long commutes to groceries - or stores with almost no fresh food‡. Most places have no farmers markets or farm stands outside of summer, and early fall. And for us at least - living off of canned and frozen food just isn't fun (at least if we've not canned/frozen it.)

This really restricts immigration which is critical economically when your town's youth mainly move to the city as is really common. These small towns are dying a death of a thousand cuts, but loosing your grocery store is a pretty big cut.

‡ My favorite story here is once when living in a small town with 2! stores for a short while, we decided to have a dish that called for cooking some spinach. Neither had fresh spinach, nor any substitute - kale say. Neither had any frozen spinach, the second store did have canned "creamed spinach" - and an ingredients list that included both condensed milk and corn syrup. We made something else.
Is that really the only response you have to large corporations artificially lowering prices to brute force local markets?

What next, are you going to defend regional monopolies by ISPs because consumers should just choose a different ISP?
> Not OP. It's more like they're willfully choosing to suffer. So in that case, enjoy your misery!

They're not "willfully choosing to suffer." They're actually starting co-ops but choosing not to call them by that word. The OP just decided to be needlessly judgemental over that, and lead us down into this stupid, prejudiced subthread.

Software engineering is craft and there are many metrices. But sadly people focus heavily on algorithm/ds only.
And? its an environmental initiative. I'm fine with more human risk. Its the greener option.

This is Germany too, so there's already a lot more riders than in the US so drivers are accustomed to see them.
Living in Western Germany I mostly see vehicles in the 10k-25k range. There is a difference if you go to the most expensive cities though, like Munich.
There is some truth to that but they already do make insane profits. This is just another icing on the cake that primarily tries to incentivize people that are already well off (as anyone that buys an electric cars right now).

While they certainly have deficiencies in the software department compared to Tesla and Germany not being the best place to test autonomous vehicles, they had electric cars for years now. The produced few because the market isn't really convinced yet.

Companies are the primary customers. Some of our workers use electric vehicles because they got a company car, but nobody owns one.

Apart from a nuclear apocalypse I don't really see the large manufacturers ceasing to exist anytime soon. They have enough capital to invest in development.
