Kinda related: in my city they introduced regular solar cells on roofs of public transport to charge the regular battery on ICE buses and apparently that averages 4-5% lower fuel consumption over a year (so - all the weather conditions, indcluding 3 months of pretty cold winter and cloudy rainy autumn), and it makes the batteries lose capacity much slower.

These buses use batteries for lots of stuff - lights, automatic doors, AC, ticket machines, external and internal displays. Apparently there are problems with batteries running empty when the buses have to wait for the next course too long. Also the batteries are losing capacity too quickly when they are charged all the way down often.

They introduced the pilot program in 2013 and in 2017 they decided to put solar cells on all the buses. Links in Polish:

top level await doesn't make async operations synchronous.

It mostly eliminates the need to have immediately evaluated wrapper async functions that we would have needed so far.

(async () => {
await foo();
})();

The added benefit is that imported scripts would be implicitly awaited upon, which has been clunky to do otherwise - you'd need to have a module that exposes an async function and expect the consumer to await on them. But the moment you do that you'd no longer be able to directly run the script through node, so you'd end up needing one more file that imports this module and runs it directly.

Availability of top-level await makes experimenting with (promise-returning) APIs in REPL much easier. It is also a bit step forward in making typescript more useful as a general purpose scripting language (outside webdev context).

I think it's a bit different. Your job wouldn't disappear if copyright disappeared. You may need to change your approach in business, but on a technical level, things stay almost the same. We were pretty much in that situation in some European countries in early 90s. (at least from enforcement point of view - lots of pirated software sold at marketplaces in the open) People still created software.
I think you've been misinformed. The trac study is looking at people who have been here for years who have been going through the system. They show up to court at very high rates.

The "don't show up for court" people were part of a program by the EOIR (which is part of the DOJ) to expedite the cases of newly arrived family units in 10 cities. They very largely did not show up. You can read about it here:

For the cost and mass of the solar panels, you can add more range with more batteries, on normal sized street cars. The math just doesn't work out well until you get to very small/light vehicles with large roof area.

In my layman's understanding of batteries doesn't the resistance of a battery increase with its level of charge? If so wouldn't these large batteries have so much resistance that at a reasonable level of charge most or a large portion of the energy would be lost as heat? Does it somehow charge individual cells as opposed to the whole thing or am I way off base?

That doesn't really show that it's amazing. You could say the same about x-x=0, even for large x. Or about any converging series. Unless all of that is amazing too - I wouldn't know, not being a mathematician.
It is’t the exponential function that’s a miracle, it’s the Maclaurin series. Think about it. The Maclaurin series says that in a very real sense, the value of a function at zero, and the value of all of its derivatives at zero, contains all of the information there is to know about it. Intuitively, this should be completely unexpected. Why in the world would the derivatives of a function evaluated at a single point tell you anything whatsoever about the value of the function arbitrarily far away from that point?

EDIT: as mentioned below, this is not true of all functions, even all functions that are infinitely differentiable at zero. But it is true for very large classes of functions.

Well for-profit prisons have been the target of pop culture for the last couple of years (e.g. John Oliver did a segment on them, Orange is the New Black, etc). People incorrectly assumed that since they were bad that it meant the public ones were somehow better (standard good vs evil thinking that plagues political discourse in the US).
The article you link to actually links to the original paper: https://www.nature.com/articles/s41562-017-0211-5.epdf

It occurred to me that the result is not necessarily unexpected if it were due to under reporting (i.e. during the slowdown there was less opportunity to report major crime and therefore reports fell). The researchers discuss that in the paper. I don't have time to read the paper in detail and come to a conclusion one way or another, but I thought it might be of interest to people who might not otherwise click on an La Times link.

> Open source has resulted in a world where you can’t make money just selling software, you have to lock people into ecosystems and services to monetize your work.

Microsoft made a lot of money selling Windows and their Office suite precisely by locking people into their ecosystem.

You say you like markets, yet you don't like others offering goods at a lower price (free software), but you do like government-enforced monopolies on ideas (patents, and even copyright). If we're diving things into 'market' and 'not market', shouldn't you categorize them in the exact opposite way as you did?

> Now, you get Android for “free” but only by turning your customers into the product.

You also get linux for free, or you can pay for Windows and still be made into the product. The only way I can see someone arriving at your position is to selectively pay attention only to cases where free software with anti-consumer features crowded out straight-forward proprietary software, and ignore cases where free software turned out good (compilers, linux, firefox, text editors, libre office, lineageOS, VLC, etc. etc. etc.)

Let me refine my point a bit. Apologies; my original post had gotten a bit long.

I agree that enthusiasm is important! And indeed, for the Go creators, their particular leanings might have been such that they couldn't get excited about building an LLVM/GCC frontend, and adapting the Plan 9 toolchain is literally the only way those three could have Go gotten off the ground. As a member of the Go team, you'd certainly know better than I.

But Go is long past a personal passion project. Go is over ten years old. Go likely has over a million developers [0]. Go 1.0 has been stable for about seven years, and the first meaningful changes to the language are just now being talked about. In my opinion, it is several years past due for Google to start investing seriously in a Go toolchain based on a mature compiler stack.

I realize the audacity of this claim and I don't make it lightly. But if I had the money to spend on a team of developers, I would spend it making llvm-as and lld fast enough and stable enough to be Go's assembler and linker, and abandon the custom Plan 9 ones.

> It never would have happened. How do you motivate people whose principal frustration is the state of C++ to work on a large C++ codebase?

Well, for one, once the language gets off the ground, you can write the frontend in the new language. Rustc manages to be almost entirely Rust, for example.

> Heterogeneity is a huge benefit to any ecosystem. Improving existing things is great, but building new things is also very important.

I agree, and I think Go is an interesting contribution to the P/L landscape—essentially it proved that stripping away a good deal of complexity (generics, inheritance, etc.) results in a very useful, highly productive language. But I don't think Go's custom assembler and linker are meaningfully contributing to the ecosystem. They're useful presently in that they improve Go developers' productivity with ultra-fast builds, but they're not suitable for use by anything but Go. Improvements to Go's linker and assembler benefit only Go. Improvements to lld or gold can benefit practically everyone using a compiled language.

We already have printable photovoltaics and a spray-on photovoltaic.
The problem is that we waste most of those twelve years that we already have people captive for. The high school years are especially egregious. It's a lot of marking time that could be much more profitably used.

Maybe 20% of my high school class ever finished a college degree, of any kind. A lot more went for a few semesters, struggled through some core classes, and flunked out with a load of debt and little else to show for it. The people that are best off are probably the ones that either went into the military or straight into a trade.

The college-prep for everyone model appears to have been a pretty bad failure. The system in my parent's generation where people were explicitly tracked and split into vocational, business, and college tracks appears to have had much better results. The gutting of vocational programs really hurts; it would be easily possible to do most of a trade apprenticeship during those years.
Apparently it's a call option on x% of the equity of your house expiring in 10 years. You are short 1 call contract but receive the premium upfront. If you sell your house before 10 years, you have to buy back the call option from Patch the company (more or less than you received depending on how the value changed).

Say you use Patch for your 1MM house, then sell it for 1.5MM 8 years later. You will be on the hook for 23%[1] or $345k.

As a homeowner, you're not really selling any equity, just a derivative based on your house's equity. If you don't sell by 10 years, I assume Patch the company can foreclose on your house if you can't deliver in cash 23% of your house's appraised value (how else would this be investable otherwise?).

The only way to be short is to own a house. But once these contracts are securitized, it's one derivative away from becoming shortable without owning the underlying (house). I'm sure investors taking the other side of these contracts will want insurance. Then you're back to synthetic CDOs.

I really hope this doesn't take off.

Same problem in Thailand. When mainland Chinese first started coming to Thailand in large numbers there was an outcry about their terrible behavior. After a while the tour operators arranged for them to mostly go places where they don't mingle with the locals.

A typical 60-cell panel today provides 300wH. Thats enough to fully charge most typical lead-acid car batteries in about 4 hours.

That's not actually true. There exist functions of a single real variable that have derivatives at the origin that are all zero, yet are nonzero. For an example, see the following:

Nevertheless, it is actually true that all complex differentiable functions satisfy this property, which is miraculous.

I'd be happy with and end to low quality patents (i.e., doing "X" but on the internet). Basically, any patent that an average software developer would violate just in their normal course of work (without prior knowledge of the specifics of a given patent, but possibly with knowledge of the problem to be solved). Of course, patent law has this covered already with the "non obvious to those skilled in the art", but this seems to have no meaning anymore.

You can extract a type from a typeguard using a conditional type!

type TypeOf<T> = (x: any) => x is (infer U) ? U : never;

I wrote a really small and simple validator library called narrows that works this way [1]. You could simplify your code like so:

import { number, optional, record, string, TypeOf } from 'narrows';

const isContactInfo = record({
address_1: string,
address_2: optional(string),
city: string,
state: string,
zip: string,
phone: number
})

type ContactInfo = TypeOf<typeof isContactInfo>;

The source is less than 50 lines and super readable if you want to dig in. The libraries in the sibling comments are great too!

Note, those financial pressures were entirely imposed. If the UK hadn't been forced to become so centralised - both politically and financially, perhaps some UK cities and towns could be trying these things.

The ridiculous thing in the UK case is the Tory reforms permitted London transport to keep their subsidy, but elsewhere must survive without. The one place not needing subsidy should be London. Even with the return of trams, the regional public transport networks are a fraction of what they once were, and nearly all routes are markedly more than London prices. Yet the need is very clearly there.

I like both patents and open source because there's a difference between innovation and infrastructure. If I bust my ass in my garage innovating my stealth widget then I'd like to protect that.

My college town's (~60k people) bus system was free for everyone to use, paid for by an extra charge on the water bill. The biggest benefit of course is not having to pay, but a close second was the time savings from not having to fiddle with money. The system ran a lot smoother because of this.

I would say this extra tax is a good thing, and I'm not at all a fan of taxes.
Another thing this would be great for is pre-cooling or heating the car before you drive it. At a CoP of 3 which is conservative for modern AC heat pumps, the 860W of solar gives you over 2.5kW of cooling.

Even if it just tempered the air whilst parked with fan ventilation through the cabin, it would massively lower the cabin temp which can reach over 90C in sunny locations.
