This is what came to mind when I read this. Far too many professional programmers are unaware of perfect hash functions. A disturbing number are unaware of pathological collision cases.

For a complete set of methods known at compile time, a minimal perfect hash is, well, kinda perfect...
Wouldn’t you just offer user-modifiable translators for such cases (presumably with some sane default)? It seems more preferable than writing the domain model in code first, resulting in N copies of the schema definition for N applications utilizing the db..

If you're not getting updates from the chip vendor, you're going to have a hard time moving to later version of Linux, for example. It would cost a lot of money to port new software to the platform, and then the question is... who's going to pay for it?

If everyone still using a Nexus 5X chips in $50 USD to fund continued development, then maybe that could continue. But it is easier at some point to just buy a new phone.
This has been something that we've been aware of as a threat in the industry for a while:

https://www.calconnect.org/news/2019/01/18/calconnect-publis...

I first spoken on a panel about it more than a year earlier than that, along with some people from 1&1 who were very keen to see progress on at least defining the risks!

But it's hard to get attention on fixing things, even in the big players (maybe especially in the big players) until there's user impact.

It's also why, from the very first moment we added this feature in our system, the default in Fastmail has been "only auto-add if it's from somebody in my addressbook". And the "from somebody in my addressbook" test checks for DKIM or SPF alignment.

We also allow turning auto-add off of course, or restricting it only to senders in a particular named addressbook group.

Yes, it's a technique to argue in bad faith and to shift the burden of proof. And let's see how it applies here...

> 3000 lines of control software? Seems a bit excessive. Why does it need a computer at all?

It really means,

> 3000 lines of control software is unbelievable. It's excessive, it doesn't even need a computer at all!

Sure, it's criticism. But I don't see any bad faith argument here. So I guess "Just asking questions" doesn't apply here.

And from the Guideline,

> Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.

So it's probably the reason for downvoting.

But consider the fact that other readers have already responded to the question/criticism with more information on the author's intention, I think downvoting this is unnecessary.
Pico hectares are a good unit of area to use for this. For a car that gets N miles/gallon, for 1/N gallons/mile, that works out to 235/N pico hectares.

That results in nice small, but not too small, numbers for most current cars, around 50 pico hectares for a Humvee in the city to around 4 pico hectares for a Prius on the highway.
Take just temperature for a moment. The second year a weather station keeps records, you would expect half of the days to be "hottest ever". (You would also expect half the days to be "coldest ever".) As you have kept records for 1/N years, you would expect something like 1/N of the time you get a new record (or less, if you assume a normal distribution). That is, you expect the number of records to decrease over time. It's the same with all the other kinds of records (sea ice, etc.)

So if you see the number of records increasing over time (modulo new data sources), then something interesting is happening. Either the center point is moving, or things are getting more extreme. If you see more records of both ends (hot and cold, say), then you can say that yes, things are getting more extreme. If you see more records on both ends, but more records for heat, then you can say that things are getting both hotter and more extreme.

I don't have to have a quantifiable prediction of what the temperature will be in order to make that observation. If it were to be cast as a prediction, it might be something like "among weather stations that have existed for at least 30 years, there will be more temperature records set next year than there were 10 years ago".

> given a common wafer thickness of around 170 micrometers

> So that comes to under 14,000 shipping containers full of wafers, which could fit in one single ship delivery, for all of the vehicles in the USA.

Taking the thickness of 170 micrometers and extrapolating this measure of a solar waffer to the needs of US cars is just ... unreal. The OP came up with a serious relation. How many containers would be needed when you measue the thickness of handable solar cells, like 3mm?
The existence of LAG and LEAD have solved some seriously iffy requirements twice in the past year now.
One time for measuring / determining from two consecutive GPS points some details about speed, route and distance (omitting some details here), LAG allowed to see and compare the previous points recorded and is IMO absolutely vital for PostGIS.

second time for calculating changes between two rows and combining that with some business rules, the existence of LAG was absolutely crucial for keeping it all in the database.

RANK / PARTITION BY is something that when you need it you really really need it. Like if you join a bunch of rows to a single column but would like to just have the first or last of those rows for results and disregard all the other rows? RANK and order by

Location matters a lot with pollution. A ton of pollution in the form of greenhouse gases released into the atmosphere is generally going to have a much larger impact than, say, a ton of pollution in the form of a solid pile of toxic waste.

Does producing lithium batteries produce much pollution in the atmosphere or in lakes, rivers, and oceans, or is it more in the toxic pile category?

The entire comment seemed constructive to me. The part I assume you take issue with was constructive, if not worded as nicely as it could have been. The comment appears at least to have been made in good faith, and it's possible that one portion wasn't meant as negatively as you took it. In any case, it's a small minority of the original content of the comment.

I would be interested in your response, as it seems you both present yourself as having good information regarding what is likely or possible in n this space, yet seem to have very different ideas as to what that is.

That tells you to how well your system of law is functioning. It's rather moot if it's not premised on equal protection.

As long as commerce keeps flowing, I think China has high enough self esteem that they'll do just fine losing some popularity, and I can't see Western corporations putting any money where their mouths are.

Actually, no corporations have really commented on the matter as far as I know, so they're not even being hypocritical. There is so much money on the line, it would have to get incredibly bloody before anyone would do anything, so I think China has lots of leeway, and I've seen nothing to indicate they're not incredibly sharp.
That's utter baffling madness! I wish that was some kind of joke instead of actually being a semi-serious explanation most of the way through.
In a swipe at Chrome, Firefox now blocks ad trackers by default
> In the absence of a true standard for browser extensions, perhaps Mozilla should consider trying to form one by leading with a strong example instead of weakly implying that they will eventually probably cave to the monopolist.

That's exactly what they've tried to do. Firefox exposes a `chrome` namespace object to extensions which is intended to be more or less API compatible with what Chrome provides and added the `browser` namespace object where improvements to the base compatibility are added (e.g. switching from callback based APIs to Promise based APIs). See the bit from the wiki below and the link to the browserext spec:

> Mozilla has worked with Microsoft and Opera to implement browser extensions so that developers can write extensions that work across multiple browsers. The preliminary specification[1] matches what Google has implemented in Chrome so that extensions will work on Chrome, Edge, Opera and Firefox.[2]

I have questions about the environmental impact of EV batteries when it comes time to replace or dispose of them. I've read a few things, including an old statement by Tesla on the topic.[1]

> Tesla: "our lithium ion cells contain no heavy metals, nor any toxic materials. In fact, our cells and Energy Storage System, by law, could be disposed of by putting them in a landfill. However, we have no intention of landfilling our ESS." They go on to say a recycling plan is being implemented. Cool.

From an RoHS POV, sure, no heavy metals. But "no toxic materials" and "ready for landfill" blows my mind. Am I naive?

I'll assume Tesla is one of the Good Guys, but I predict worse players in the industry will take advantage of loose disposal regulations if there is short term benefit.

It's been a while in the Laptop segment that there was free choice and you really had the feeling to own your device, sadly.
Some family members of mine work for a company that makes lead-acid batteries- and that same company also just happens to be the largest lead-recycling company in the world as well- because mining it costs more than recycling it.

I look forward to the future here- it doesn't seem like an unsolvable problem for the engineers at ${battery recycler} to go from lead-acid to NiMH or LiFePo4 or LiPo or whatever it is.

Uh what?

Do you have a link showing that? Stripping half a metre of a cable just to attach a connector seems wild.

Did you use too many zeros?
You got some of that mixed up.

First there was USB 3.0. Technically the standard included older speeds, but people called the new one "3.0" and all was good.

Then 3.1 came out. But what about the poor manufacturers with 3.0-speed ports? Well, someone decided they could call those ports "3.1 Gen 1".

And it was all downhill from there. 3.1 Gen 1 became 3.2 Gen 1, and now becomes USB4 Gen 1. They added more "Gens", even ones where the word "generation" makes no sense. Now the number tells you nothing about speed, and there are two separate nomenclatures for speed that are both confusing.

And I'm still not sure if they did or did not ever implement Gen 1x2...

(It being USB4 instead of USB 4.0 is another stupid poke in the eye on top of everything else.)
FourSquare could have been this, when they were good. They have many restaurants, photos, tips, photos of the paper menu, etc. Google Maps caught up and it, and from places I have been in Europe, Asia, and middle East, their photos, review, and information seem accurate and helpful enough.
It's not just a question of design philosophy. Samsung software is often riddled with bugs, things don't work, features removed relative to stock android, forcing inferior version on us (like their keyboard...), then on top of it all the crapware, the fake android store, the lack of updates, etc. etc.
Introduction shouldn't be complicated to explain in plain english. Instead of introducing to the concept, it misleads from the beginning.

> AFAIK, macOS is aware of three different states

So, you're correct, and I actually did not know this when I wrote the post you've replied to.

But the point still stands: regardless of which of icon 2) or 3) you get, it still isn't going to alert you to the issue: both are normal icons. 2) appears during a full charge, since then you are also not charging, but connected to power. That is, regardless of 2) or 3), both icons also appear during a normal, actually charging charge cycle, so neither indicates an issue.

> I'm pretty sure macOS always takes action when the battery is about to die unrelated to the state

As I recall it, it was awfully close. But that's not to say that there wasn't still time, and that the OS couldn't have acted. (I didn't drive it to empty to find out!) So, it could be that I'm wrong on this point.
Indeed, but contrary to typical articles who basically headline "WATER FROM THIN AIR!" this one actually explains the novelty of the process and acknowledges it depends on air humidity. It is not just a solar-powered condenser.

Assuming that you're generally healthy, not deprived of sleep or otherwise dealing with fatigue, and you don't have sleep apnea, this sounds like a classic description of ADHD. I'm not a doctor though, so take it with a grain of salt; do your research and/or talk to a licensed professional if you have concerns.

My experience of ADHD feels like getting distracted by my own thoughts. Mind wandering at inopportune times, or random thoughts popping into my head. It tends to happen when I'm not effectively engaged by what I'm reading or who I'm listening to.

I generally try to be mindful and aware of my attention and thoughts, to refocus whenever I notice myself wandering off. I try this as frequently as possible, and try to build a habit out of it.

When listening to others explain things, I try to be an active listener. Rephrase what they just said in your own words, as best you can. Engage in discussion whenever possible/polite.

When reading, I like to Doodle, rewrite in my own words, or otherwise find ways to engage with what I'm reading.

Generally, improving one's focus takes time and practice, like any other skill.

Hotkeys.js: A robust JavaScript library for capturing input and key combinations
The law may not state it but economics does. Even the cheapest insurance plans cost 500/mo. If you drive an hour a month and earn $100 for the month, it is not cost effective to issue a full health plan for that. There is a break even point of course. But that break even point will not allow driver flexibility.
> If you're thinking in the first terms, is a relational DB the right backing store, or wouldn't it be better to back your DB with something more like Mongo?

Certainly relational like for 90% of the cases, if not all.

The relational model is THE answer to nosql from the start (ie: it was the solution of the originals "nosql").

Is totally more flexible, powerful, dynamic, expressive... And that without talking about ACID!

You can model all "nosql" stores with tables. With limited exceptions it will work very fine for most uses...

> This is simply a standard management question with very little technical relevance.

I don't get what your are implicating here...

But nosql solutions are the ones to be suspected and the ones to requiere a harder qualifications and justifications to use. Is the wrong choice in the hands of the naive. "NoSql" is for experts and for niche/specific workloads.
