I worked for a solar installer company for a while last year and we were doing a training in preparation for building out our first installation of a Tesla solar roof. I didn't participate in the build, but was helping the installers with the training.

To your supposition about the construction and shading, the solar roof tiles are tempered glass plates with clips that mate with plastic standoff roof mounts, so there is a ~35mm air gap beneath the tiles and the roof membrane.

This is the pathway that the electrical cables route to interconnect the tiles and other needed electrical appurtenances like electric feed-throughs, mppt devices and inline disconnects to satisfy newer NEC rules about the maximum string voltage in a system shutdown.

The clip in design also allows for individual tiles to be removed and replaced without disturbing those around them, although scaling a glass roof sounds harrowing.

I will say that the roof quality needed to execute the solar roofing system was intense. There was very little affordance for shimming the tiles into the plane, which seemed a oversight in design. The whole roof deck needed to be coplanar to (going from memory) ~1". In our area this would be rare to find houses with this quality of roof deck, requiring significant reworking to rip the decking and shim the supporting structure from below. Our housing stock is old.

The estimated installation time was on the order of 10X of a traditional above-the-roof solar system at weeks vs ~2 days. The install really needed people with the skills of a roofer, which wasn't a significant overlap with the skills of a normal roof working solar installer.
XPath is the real killer feature for parsing XML. I don't think it's possible to use it in this particular example, but in the more generally useful cases where you want to pull (eg) all subnodes with key matching a particular string, XPath is great.

Here's it being used in real code (search for "xpath_"):

According to micro[2] which was one of the first "scooters" before they went electric:

"Our scooters are manufactured in China and Germany. Our factories are all certified with the international quality standard ISO 9002. Our products are all manufactured according to the ASTM, EN, ANSI and TUV standards to guarantee maximum quality." [1]

There seems to be a basic logic issue here. Maybe an example will help. If you argue "all swans are white" then to disprove your theory all I have to do is identify a single black swan. One is enough, and presenting such a black swan is not "cherry picking" because the original theory was total and had no exceptions: it posited the absence of "cherries".

If your response is, "well obviously all swans are white in this part of the lake" then you've lost the argument, because your original theory is the one being debated, not one with a random ad-hoc revision that makes no sense.

Arguments about Sweden and lockdown are like this. The debate in question is whether lockdowns were required. Their justification is entirely based on models that claim to accurately simulate the counter-factual: that not locking down will yield enormous death numbers. To disprove this theory and thus eliminate it as the justification for lockdowns only requires one counter example, because the original theory is total and has no exceptions for proximity to Stockholm/Nordic culture/whatever today's excuse is.

Now as I've pointed out, Sweden is not the only counter-example, there are quite a few in different parts of the world. But that doesn't matter because by the nature of the original claim, a single counter-example is sufficient. To re-establish a justification for lockdowns would require a revised theory that is actually coherent and explains all the exceptions, not just a single one: this is basic logic.
Nothing I said is controversial, if you want to read about Israel’s strong influence on US middle east policy, I suggest the seminal work by Meatsheimer and Walt.
There is a categorical difference between the Space Shuttle boosters and the Falcon 9 rockets. First of all, the external tank of the space shuttle didn't get reused. The solid rocket boosters were, but only after they were recovered from splash-landing into the ocean, requiring extensive and expensive refurbishing before further launches. Which Falcon 9 boosters largely avoid by landing vertically.

And the Shuttle itself was reusable, but that's sort of besides the point, as that's a space-plane, not a rocket used to bring things into orbit. Whether capsules or space-planes is a better concept for the spacecraft itself is a different discussion altogether.

The per kg cost to orbit of Falcon 9 launches is an order of magnitude less than it was for Space Shuttle, so credit should be given where credit is due.

A good thing to read is https://joss.theoj.org/papers/10.21105/joss.02704

The focus of this package is on the "plubming" of auto-ml solutions. The work of designing solutions based on multiple discovered models is rather unsupported in the current state of the art, and this package looks quite supportive of it.

A big contribution (if it works in practice) is the idea of a scientific type describing what data is and how it should be mapped to algorithms - a systematic way of doing this is the underpinning of a process for model selection.
Or "we didn't do the math but have an excessive confidence in our security".

Or "this thing costs us $300 to make, we can replace it 5 times and still make a profit".
I do realize that. I’m honestly wondering if a carrier in the US or overseas is okay with users consistently using 1-3TB a month on one normal cellular/wireless line.
Flask was originally an April fools joke with what the author thought was a silly design. It is now widely used, including in production systems at my company.

Have you verified that? I'm pretty sure that occurs using the JPA API and Hibernate. I'm not sure if other JPA providers do this as well.
systemd is exactly the boot time interpreter you're asking for.
Its rather easy to emphasize with him. You have to breath. He has to breath. Try holding your breath until you absolutely can't do it any longer then imagine someone was keeping you from taking that breath. See trivial.

He wasn't killed while doing a home invasion or even because of it. He was wantonly senselessly murdered by someone who figured they could trivially get away with it by being deliberately smothered for over nine entire minutes when he was accused of passing a fake 20.

There can be no increase of justice obtained by unjust means, no decency obtained by indecent means, no peace in our streets obtained by unlawful violence by men who have no respect nor love for the law but kill under color of law and degrade and destroy the power of this essential institution to preserve this peace by their actions.

You say casually that we wont be missed by most but if we allow this behavior to continue we have a lot to lose and much to miss starting with peace. If the Derek Chauvins, trash in uniform, are allowed to dispense death penalties I cannot imagine why you believe they will reserve their wrath for the especially guilty. Something that ultimately we struggle to accurately judge when given the benefit of careful deliberation and extensive process.

There are many more worthy victims than Floyd but if we can't punish his killers for killing him slowly and deliberately I have little hope that they are future victims will receive justice.
Since Windows Vista, at least. I remember being quite surprised by how well it worked - I could dictate and there were very few mistakes.

I was particularly taken with how it understood commands. It was amazing to me that it could understand "open Firefox" and "open mIRC", since I figured it must have had to guess how arbitrary program names were pronounced.

But yeah, here we are with pocket-sized devices supposedly more powerful than the computers of the time, which have to send off everything to The Cloud for approximately the same quality recognition. Progress!

I wanted to do something similar, but I found Jekyll quite bloated. Pelican didn't work for syntax highlighting. I found Hugo the best. My current stack is Hugo with terminal theme hosted on GitHub pages.
It seems to have reached the front page too quickly, it landed directly at the 6th position when it had only a score of 3: http://hnrankings.info/26777008/, which drove it to the top.

I guess it's an aberration of the HN ranking algorithm.
> start the work

Not the work, but some work.

You want to procrastinate on something most similar to what you are doing. So if you are on YouTube, start coding. Then when you are coding, its just a matter of switching to coding that thing you should be doing.
The GitHub docs speak of being able to do single donations but I’ve not seen the option yet. Is it something you need to explicitly configure as the one being sponsored?
Eventually as others say. The wiki for it goes over the different selling points. Even with Pinboard it was and still is first frozen in place. I think soon it’ll be working again in some capacity.

And yeah the final sale to Pinboard was for literal 5 figure peanuts. While I think it was 1000x more when YouTube founders bought it.
It's just never worked out to justify itself by the stakeholders who would approve such a thing. The standard gaming hardware configuration has always tended towards a little bit of general purpose computing capability plus a very focused specialization in graphics. And the standard incentive structure of game production tends towards a rapid deployment of assets authored in general-purpose content creation software, not a game driven by new algorithms. These things drive away from the experimental places where FPGAs could shine - unique ways of creating audio and video signals, customized inner loop optimizations, etc. The first thing everyone will be asking is "OK, but how do I make it portable?"
Those installation prices seem crazy?

I live in Australia, and last year I had 13kw worth of solar panels, with a 10kw inverter installed on my roof for $10k AUD (about $8k USD).

Our federal government does some subisidies, so I believe the raw cost was closer to $15k. But either way, that is substantially lower than what is quoted here?

Why would anyone pay $70k USD for solar?

So you jam the GPS (and/or the Internet connection), take the scooter to your garage then what? Always ride it with the jammer?

I don't know how these ones are made but the electronics can be made hard to remove without damaging the scooter. Or say the manufacturer can make the cost of the operation so high that it won't make sense to steal them. Or, the tracking and control components can be so tightly integrated that removing the tracking ones you'll make the scooter inoperable.

Not saying these particular scooters are well protected from all this because I have no idea, but theoretically possible to achieve.
The complication is the people who've spent money (e.g. cleared trees) predicated on getting a solar roof; IIRC you can sue for certain values of "I did X predicated on the other party's assurance they would do Y".
Amazing how people still put up with this nonsense. Bash really has no place in this age.
> Using the FPGA for complex simulations like physic? Would that make any sense?

The graphics card is specialised for this and has better cost/performance. Graphics cards basically are specialised gaming hardware optimised as much as possible for that use case.

Trying to teach games programmers to use FPGA tooling would be a spectacular disaster. Oh, and FPGA toolchain-targeting is to a specific device; you probably don't remember the early days when games would target a specific model of 3DFX card, but that's what you'd go back to. Upgrade your hardware and you need recompiled versions of all your games.

The one case where it might make sense is if you focus on latency to a brutal extent. DisplayPort on one side of the FPGA, wired game controller (NOT USB) on the other. A unique experience that's hard for normal systems to replicate.

I want a “how to draw Tolkien maps” article by this guy that gives examples of trees, mountains, cities, etc... in a point by point way and the tricks to making the style work.

There’s more on his website to learn from examples so I’ll start there I suppose: https://middleearthsmaps.com/pages/about

Edit: for some of the HN crowd, this one is likely of interest, https://middleearthsmaps.com/collections/my-favourite-square...
Oh, I know. There's that, and File::Slurp, and a bunch of other stuff one would think would exist from the start, but for some reason don't. But those are all external modules that somebody had to write, that didn't exist at some point in time, and which sometimes one can't use because in some cases you can only rely in what's in core.

I'm just wondering at that bizarrely enough, Larry Wall (or somebody else) found it useful to have a simple, convenient way to execute a command with exact arguments, but not for when you need its output.

I must have written the same wrapper around open() several dozen times by now, due to needing to write scripts for cases where installing dependencies is undesirable.
The printed money is starting to have effects? (I am not an expert in money.) https://news.ycombinator.com/item?id=25828461
Yeah, I can't see it having a huge effect. Here in Queensland, Australia, where every second house has regular panels I have never heard of people thinking they confer bragging rights.
I don’t see much of a difference. It’s obvious this was going to happen. Is there any instance of a big site that doesn’t go this way? It seems as if sometimes people will always act surprised when sites monetize heavily. As if the site was always going to remain as basic as it was in its early days while growing. This is almost never the case except in cases where it goes paid [only]. Even those have exceptions (newspaper sites vs Substack)
One should maybe distinguish the model (eg Black Scholes market (fixed vol), Dupire local vol, Heston stochastic vol, Merton jump diffusion, etc.) from the technique one uses to compute prices within the model (analytic closed form, PDE, tree (binomial or trinomial), Monte Carlo, other numeric methods).

All of the models (and techniques) I mentioned were well known and in use by 2000.
I'm interested in sources that establish "how the majority of the public uses TVs". I've personally never seen anyone use TVs in line with the recommendations from TV manufacturers screen size and viewing distance. Maybe this is a USA cultural thing (or, contrary, maybe my own observed viewing habits are a cultural AU/NZ thing).

Complex queries with multiple joins? jOOQ.

Persist changes to complex aggregate models with multiple layers of child entities? JPA/Hibernate.
No, systemd doesn't really interpret much, unit files are mostly not a full replacement for what init-scripts were capable of. Which leads to lots of Exec=/some/shell/script.sh in unit files which is worse than before because now you have multiple files and more strange interactions.
Damn, didn't know about that! Impressive thing!
Is this actually applied properly and consistently? How is a Patreon of videos or audio different than Spotify or Netflix? Didn’t they both have to remove being able to subscribe via their iOS apps unless they wanted to lose a 30% cut? This makes it completely arbitrary then. As I can subscribe to a new Patreon in the app still.

> Why is American stimulus not comparable to Zimbabwean stimulus?

Well, for one thing, the US wasn’t engaging in a massive and extended campaign of expropriation of productive assets that was destroying the core of the economy over a period of years while printing orders of magnitude more dollars than had ever existed, when inflation by traditional measures waa already significant when the money printing started.
It does, but it's not convenient. You need a loop, perhaps deal with $/, close it at the end.

I'm not saying it can't be done, just that the language is oddly lacking in convenience for this use case.
Liheap Map State and Territory Contact Listing
Mandatory user tracking is one thing I don't like in the new electric mobility products. I don't want a "smart" always-connected bicycle, scooter, or car. I want a completely offline system with an on-off button.

At least with conventional cars there is an option to skip BMWs and get a dumb car. There are vacuum cleaners which don't need an app to work. e-bikes can be used without an app. If I need anything online, I have a phone.
At the beginning of the stop he disclosed several issues that would lead to extreme anxiety and panic attacks, which cause difficulty breathing, including previous trauma associated with police and claustrophobia. The fact that he also couldn't breathe before he was being suffocated by police doesn't mean he lied.

(And of course it goes without saying that even if he did lie, it doesn't justify being murdered).

Am I the only one who was thinking "wow a bit of edge finding, a tolkien font and I have a business"

Maybe not.
Scooters are superior in portability. If you also need to move up/down stairs or take public transport, the scooter is often easier. Storage (especially at your destination) is another thing someone pointed out. If I save 5 minutes on my commute but now have to take a 5 minute detour to the bike room, I didn't win anything.

Also, in many cities taking bikes in public transit is restricted (e.g. only outside rush hour) and/or you have to pay for the privilege. Scooters often don't fall under this rule.

Price is another factor. A non-electric scooter costs $50, new. That makes it cheap enough that you don't have to worry too much about theft, which makes handling it a lot simpler (no fiddling with a lock). This increases convenience, making it more useful. A normal electric scooter is still cheaper than an electric bike. Doesn't apply to this model obviously.
This is just not true.

>Paramedics were called and injected McClain with ketamine, but they incorrectly estimated his weight, giving him more than 1½ times the dose he should have received. He got 500 milligrams because they thought he weighed 220 pounds, but he weighed only 140 pounds and should have received 315 milligrams.

https://www.latimes.com/world-nation/story/2020-08-22/ketami...

It is a matter of record that they injected him with 50% more than he ought to have received. As for your claim. It's not merely that this isn't true it isn't so far as I can discover even claimed by the police.

It's not even clear what you mean by the words "the prosecution" he didn't get tried for anything whatsoever by dint of being already dead because they screwed up and provably killed him.
Whether it is legal or not depends on the contracts people originally signed with them. There's no point speculating without looking at the text.

Yeah. Your sibling comment drew a distinction, but it seems that distinction has arbitrary holes in its consistency as well. I’m sure if Patreon 50x’ed revenue and traffic starting next month — Apple would begin treating them more harshly.

Bash has multiple better solutions to this. This is a really really really old hack. New code that uses it is either trying to be backwards compatible to the extreme or is more likely just someone unthinkingly copying what they’ve been taught or seen.

Thanks for that tip, I've benefitted from Shellcheck a bunch of times so I've just sponsored and wouldn't have without your comment.

I've puttered along for years writing little bash scripts for one thing or another and always had the uneasy feeling that I was littering them with errors.

Shellcheck's linting showed me (a) that I was right and (b) how to fix them. It's made me a better developer and I'm so grateful for it!
Some context on the price and product: I'm not affiliated with the manufacturers of this, but I own their previous model and have used their scooter rent service in Tallinn extensively. Compared to Xiaomi/Ninebot etc these are much-much more comfortable to ride.

The larger platform to stand on makes it quite stable and the brakes are much better as well. Just my two cents.
There's also the health benefits. Unless you have health issues no one needs assistance in walking or cycling unless the distance is long and I'm guessing then that it would be too far for an electric scooter too.

I used to use a manual scooter to get to work and it was a lot of fun and good exercise - although the harder wheels back then were hell on my knees.
