I’m almost certain 20 miles range gained in 8 hours is not realistic. The website claims the average for this car is 112km (69.6 mi) per week. The claim of up to 245km per week is a bit misleading.

Looking at the chart they provide, that assumes perfect conditions in the month of June only. A sunny week in December will only provide 70km.

But going off the stated ‘average’ of 69.6 miles a week, roughly 10 miles for a whole day of collecting sun. You might get nice returns on a sunny day in the summer, but in general year round, your probably lucky to get 3-5 miles.

Elon Musk spoke about this on Joe Rogan recently, and said it’s just not worth it. The return on investment is just so small, and we’ve essentially reached the technical limits of what solar panels can provide. So we will likely never see this in a Tesla.

There are zinc batteries as well, that you can buy today by https://redflow.com/ . It looks relatively simple to me, during charging it's just electroplating zinc. (I'm not a chemist.)
I would argue that states and municipalities would continue to pay whatever was necessary to keep the roads passable for families and commerce. They’ll have to pass it on with tax increases or service cuts elsewhere. To allow the roads to get worse in the face of monopolistic pricing isn’t an option.
Consider it'll be charging, even if a little, all the time the car is in the open air at daytime.

In shopping mall parking lots there is often some chargers, but more often than not they seem to be occupied. With a car like this, unless you drive a lot, you can park the car anywhere in the parking lot and not think about the charger.

My pre-COVID commute was about 28 km if I chose the scenic route with no traffic lights, or 12 if I crossed the city (I usually took mass transit, so I could read instead of drive). My post-COVID commute will probably be much smaller, as we are all going remote with sporadic visits to the office. I can get to the beach or the mountains within 5 km. For my post-COVID needs, this car would almost never need to be plugged (maybe during winter because these latitudes make the days short).

The boring answer is that most "sexy" features don't make that much of a difference. However, a lot of spreadsheet or manually processed data being automated is well over 10x improvement for a customer. Headline features like AI don't make nearly as much of a difference as not having to perform repetitive manual labor.

Y'all seem to me to be selectively quoting from the statement to make it seem like they're attacking or attempting to destroy nuclear families when the full text shows that they are extending the concept of family from the nuclear family to a larger group.

Not at all. Go still uses a very primitive pre-80ies stop the world, non-compacting, mark & sweep collector. Stone aged.

This paper describes a slightly improved version of Bakers classic two finger collector with generations, as used in all modern GC systems since the mid 80ies. Normally you just use two semi-spaces plus the generation region. This one uses much more generational regions, which was modern in the 80-90ies, but fell out if favor with modern vmm's. Swapping semi-spaces are so much faster. They claim better compaction, which is interesting. Lisp people, like LispWorks should know better, as they tried those things excessively.

"ideas put on paper" is oversimplifying it. There's a lot more work and time involved in creating art. It's not like: I have an idea, I "put it on paper", and 10 minutes later I have something to "claim dominion over".
iOS pausing music when unplugging headphones. Totally obvious nowadays, but a revolution to me when I experienced it the first time (coming from Nokia). It was one key experience that shifted my perception of my phone as something that needed to be “managed” to do what I wanted to something that supports me throughout the day
>Have you never used map or filter operations on streams of data?

If that's the standard for complicated programs, then I really don't understand how types can get confusing; filter doesn't even change the types of its arguments. I guess structs of several promises are a good example because you could mix up which fields contained which future objects, and that code would be distant from the API call to produce the object.
just noting also - if you were to make 1p per song without any of my proposed limitations or similar then given the fact that people consume the songs they loved in their 20s all their lives, if you could manage to have a couple top streaming hits for that age group for a couple years you might just be able to go fishing for the rest of your life!

Hughes can do that if anyone can. I know among the right, Ben Shapiro is often viewed as the great argument destroyer but I think Hughes could give him a run for his money.
I agree "I don't know what this organization is doing with their money" is not a strong argument, but I think just asking what a non profit is doing with it's money is also not a very compelling argument. I don't know much about this organization, but I know a fair amount about the BLM movement, and the local organizers or groups I've interacted with which I've made clear is where my argument is coming from.
Of course, although I'm assuming you meant that as a rebuttal? Keep in mind that output does not always need to be physical. In fact, the history of capitalism shows that growth is coupled with more people doing less physical work and that countries with greater wealth and resources (e.g. the ability to make more stuff more efficiently) will move towards a service oriented economy.
I worked on an old Honda Odyssey that I bought used from a friend for $100. It took at least $2000 in parts but I could find all the parts on RockAuto.com (The site is ugly but functional). Just like cars, in the long-run, I think bringing products to market which are repairable will help create trust between manufacturer and end-user. In fact, the resale value of an older item depends on the affordability of the repair.

Gmail also automatically saved drafts. I can't tell you how many long emails I wrote and lost before hitting the send button with other web email UIs.

Our technology choices for the backend are incredibly straightforward. The tricky bits are principally .NET Core and SQLite. One new technology we really like is Blazor, because their server-side mode of operation fits perfectly with our "everything on 1 server" grain, and obviates the need for additional front-end dependencies or APIs.

> Incidentally, I think this happens somewhat automatically; as in, humans naturally mirror the accents around them, or at least subconsciously change their dialect to be understood better. I think it works the other way around too - people might subconsciously mumble things they'd rather not say.

I studied in an English speaking middle school, in a Spanish speaking country. Only a few of our classmates were native U.S. English speakers and we occasionally picked up words from them, from music or movies.

> You can pick up accents, both pronunciation, phrasing and vocabulary this way. Incidentally, this is why I dislike (find divisive) the fact the Afro-Americans use the N-word liberally - I don't think it would be hard for an non-PoC to accidentally pick up the word if they often communicated with people who used it.

At some point, when we were about 13 years old, my classmates picked up the "N-word", perhaps from a song or from a movie. And we started using them between ourselves (classmates) during recess and lunchtime.

This went unnoticed for some time. Even by some of our local teachers.

That lasted for some weeks until an U.S. American teacher heard us. Then he took us to the classroom and spent the class explaining to us that not everyone could use that word. We spoke about how some people may use it and other not. While Spanish does not have this restriction, English does.

For example he explained to us that because he was white, there was no way he could use it. Then he looked at us, and told us that some of us _may_ be able to use it depending on our skin color, but not all of us. That it should be better for us not to use it.
Electronics now come to me from Best Buy, Microcenter, and Newegg. Best Buy in particular has faster shipping than Prime. It's frequently overnight for in stock items. At least in my area. And as far as I know, there's no problems with counterfeit goods with them.

Physical books I buy from a small online bookstore I want to support. Oddly enough, they're not much slower than Prime. Even for books not in stock. Plus, they frequently write a nice note, or slip a free zine or custom bookmark into the package. It's a nice touch, and whoever did the packing has equity in the company. They're worker-owned.

Ebooks are still Amazon, though I strip the DRM immediately after purchase so I'm not locked into the Kindle ecosystem. I may try buying a test book from Kobo or Barnes & Noble to see if I can just as easily strip the DRM from them. If so, then I'll probably switch.

Ebay's been good for some stuff. For Pi hobby stuff, I've started buying directly from the various small businesses that specialize. The shipping is longer, but that's not a problem so far.

Some stuff I do buy from Walmart / Sams. They're about as bad as Amazon in many ways, but they do pay their warehouse people a decent wage. Or they did last time I checked. So it's at least marginally better in that respect, and there's not much worry about fake goods from them.
Still on Java 8 at work :-/
That’s also not accurate. Browsers and apps have had the ability to ask for the system-defined light or dark mode since 2015. They simply chose not to until iOS could do it, so you’re right that the popularization came from mobile. Windows 10 was trying to be a mobile OS in 2015, so I suppose you might count dark/light theme support as a mobile innovation regardless.

Edit: the reason I mentioned it in the first place is that the author chose to lead the second paragraph of his article with a major factual error, and it’s worthwhile to have a clear understanding of the history. It’s like if I wrote an article about Jetpack Compose, and the second paragraph started with “Apple chose to follow the wildly successful trend of Android by coming out with the iPhone, and the success of Jetpack Compose by coming out with SwiftUI”. I’m disappointed that the only reaction to seeing that pointed out is for others to double down on the false assertions.

Watching the video that coldtea posted, no, it is not. Ubuntu and most of its derivatives have very easy installers, and take a fraction of the time. The video didn't even include the time it would take to read and understand all the terms and conditions!
Yes you can. I'm using the Fritz2 framework, which is pretty nice. There's another one called KVision. There are also some people doing react in Kotlin. You can also just program straight against the browser APIs as they have nice Kotlin DSLs for large parts of that.

Basically, to stay on topic, there are currently multiple kotlin compilers, including one that transpiles to Javascript. There is also tooling to interface with npms, to adapt typescript type mappings to Kotlin, and a few more goodies. Basically you lose the java standard library but you gain access to the browser APIs. Node API mappings are more of a work in progress but you should be able to target node.js as well. Browser side kotlin-js is pretty nice. You can do pretty much everything that you would normally do in js/ts. The build tooling uses gradle, which underneath uses webpack. There's a dead code eliminator, source maps, minification, etc.

Our web app uses cordova (for IOS and Android wrappers) with a few plugins, integrates Leaflet for maps, has reactive components (using co-routines and flows), has styled components, etc. So, pretty nice and modern way to do frontend. We have a handful of js things we integrate (like leaflet) and quite a few Kotlin multi platform things (like our own API client).

There is also a js backend for the new IR compiler, which is the thing that Jetbrains is currently building to unify the many Kotlin compilers they have. There is also a wasm compiler backend for that in the works but it's to early to rely on that probably. The IR to JVM backend is currently in beta and kotlin native also uses the IR compiler.

Kotlin-js is not for everyone just yet (a lot of these tools are beta quality) but if you are more comfortable with Kotlin than js/ts, it's worth checking out. That being said, our setup is quite nice compared to some react train wrecks I've been involved with.

>> salt to melt snow

Who does that? Salt is used to melt ice, not snow.

>>Raised vehicles like trucks and SUVs ... to avoid getting stuck in the snow.

"Raised" vehicles are not tall because of snow. That clearance is for off-road driving, not snow on a road. Any public road would be closed long before snow became so deep as to actually require a car to have greater ground clearance. If anything, a taller vehicle is more of a liability on a slippery road. The ideal vehicle for winter on road driving is any 4WD/AWD car with some good snow tires and a modern traction control system.

> We disrupt the Western-prescribed nuclear family structure

But the real question is, what does this have to do with racial justice? As someone like Sowell points out, many inequities are themselves the consequence of disrupting the two-parent household.
Not as crazy as making "mixed oxide" fuel with a high-energy ball mill. (e.g. the ball mill can turn sand into deadly nanoparticles, just think what it can do with plutonium!)
> In SQL you go from primitives straight to tables

This make a lot of sense. Because primitives ARE "tables", columns ARE "tables".

A primitive is a relation of one column/row. This is what allow you to do:

SELECT * FROM (SELECT 1)a

What sql/rdbms not do it well is to exploit this very well.
Good thread, thanks for the link. It is over 2 years old though.
Around here, they use grit instead of a fine sand. It doesn't matter as mcuh if there is a melt and freeze cycle. Since the grit is around the size of a pea, it leaves textured ice.

Don't get me wrong, you can still slip and fall, but I can catch myself more often and tires seem to do well enough.
SSDs.

Virtualization.

Git. I've used CVS and SourceSafe before.

LVM. The old MBR way of partitioning is just awful.

systemd and journald, just to be a bit controversial. I really don't miss my days of screwing around with init scripts, or having to parse logs by hand.

Arduino. It makes lots of cool stuff very accessible.

sshfs, it's amazingly convenient.

pulseaudio. Sound on Linux finally works. I spent an unbelievable amount of time fighting with it before.

valgrind. Amazing for debugging memory issues.

Modern hardware. It's only recently that I'm no longer tightly restricted by RAM, disk space or the CPU. I remember the hours spent on freeing up conventional memory, a kernel taking 3 hours to compile, and having room for half the stuff I wanted to install.
No it's not really relevant, but then neither is the Friggebod, which was the subject of the parent of my comment.

Configuration management.

A few years ago, I timed myself doing a full reinstall on my private notebook to switch to a different partition layout. I was done in 30 minutes, of which most of the time was spent waiting for packages to download and install and for the /home backup to restore. Without configuration management, this would have been a full day of work just installing stuff and figuring out things like "how do you enable palm detection on that touchpad model again".
I wonder if that's a difference in the level of support for risc-v in gdb vs lldb, or maybe that lldb has had less effort put into the "I'm a system debugger" use case, or just an interoperability thing where the QEMU gdb stub mostly gets tested against gdb and not against lldb ?

(One of the unfortunate things about the gdb remote protocol is that there is no kind of test suite or conformance test for implementations of it as either a debug-stub or as a debugger, so testing is often limited to "does this stub work with the debugger I happened to test it against". I'm pretty sure most QEMU developers use gdb, not lldb, when using the gdbstub.)
I think this has an undervalued benefit: if you run out of charge somehow, the trickle will let you limp to the charging station.

Like, EVs going fast take far more power than cars going slow due to wind resistance, so if you're travelling 5KM/hr then you'll take an order of magnitude less power. And if you do run out of power, you only need to get to the nearest wall plug or charger.

Obviously, cost makes this a very niche feature currently and generally you shouldn't run out of battery in most situations anyway. That said, this could be a good "better late than never" sort of thing on luxury cars.

In my opinion, I think the best way to implement this is something like the repairability labels, like how it's done in the EU. Not sure how to pick who gets to decide what goes on the labels, however.

Chiming in from the Midwest USA: cars manufactured with galvanized (https://en.wikipedia.org/wiki/Galvanization) metal seem to fair better in my experience. That said, galvanization isn't terribly common and as you mentioned, if you really care about your car you should store it in the winter.

Call me crazy but I think the deal between the two is dramatically different up front, even what everyone does.

End customer's don't have any equity... in the end neither did the employees. That's the same, unfortunately. But they're the same that way.

I think those are two dramatically different deals you're making with people, pretending they should be the same seems oblivious to the actual relationships.
