"TL;DR: C++20 may well be as big a release as C++11."

I feel like with the addition of modules this may be a release of the language spec that is going to need at least a decade to settle in. I hope the next few changes are more incremental.

I am very excited for modules. Hell, maybe I'll even see them used some day in the chromium code base I work in.

Tesla sells ~25k vehicles a month to customers (enough that they’ve cannablized sales from BMW in California) who don’t mind stopping at fast DC charging stations. The market has spoken (wrt EV vs PHEV).

While the Volt had a niche, it seems it wasn’t competitive enough versus newer market competitors.
This is definitely true. Every time an explanation falls flat, I realize how I don't really understand the thing I am trying to explain...
People with living parents and grandparents would have likely had a better chance of survival than those without living family members. Thus, those with genes that have adapted to live longer and healthier would still have had an evolutionary benefit, despite no reproductive benefits.

It might be true even today, let alone in the caveman era.

Hmm... a non-commercial glassdoor-alike is an interesting proposition.
The harmonic content of a sound is a big component of how we hear it, but the articulation over time of the sound also plays a significant role. This is referred to as the ADSR (Attack Decay Sustain Release) envelope. I would also imagine that each harmonic of a sound has its own slightly different ADSR envelope, so that harmonic profile would change over the duration of the sound.
But seriously that is strange
I don't understand these naming conventions either! Someone told me the Model X was an SUV - I thought it was a hatchback! I mean it's the same outline as something like a Volkswagen Golf isn't it? Why is one an SUV and the other a hatchback?
Fascinating. I'd put a bit more faith in this one on the grounds that 1) the Navy probably wouldn't waste legal cycles on filling this one if it hadn't been reduced to practice, and 2) there looks like there's still energy lost to heat, if I'm reading correctly:

> An electromagnetic coil is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity.

I'm presuming there's still energy loss taking place with the coil that wraps the wire. So it seems you enable superconductivity and some of its associated benefits but you're still going to have some energy loss since it's... for lack of a better term, an active superconductor rather than a passive one.

I wonder if the heat output of the coil is drastically reduced compared to the heat you'd get from electrifying e.g. the sort of cable this seeks to replace?

I don't need to spend hours charging my car if I want to go beyond my commute. I simply go to a normal gas station and my Volt effectively functions as a hybrid. With gas, Volts have a 300 mile range.

Also if my charger somehow fails in the middle of the night, I can still drive to work without issues.
You still shift it into park/drive/reverse. I've been in one but don't remember having a problem with it, besides the atrocious visibility.
I agree. I don’t walk around with mine during standard hours. I usually also only wear the one that people can’t see when they come into my hours, and I apologize if someone says something to me while I have them in. I think it’s very important to appear accessible and to hear and participate in serendipitous conversation.
They also never advertised it at all. The only people who knew about them either researched them or heard about them from word of mouth.

The total absense of advertising for a vehicle that so many people loved has always reeked of lack of commitment from one side of the house.

That doesn’t even factor in how Chevy dealerships would actively try to talk you out of them.
I think they might mean the shifter to change from park/drive/reverse/neutral
Please provide any evidence for your claim.
I've been on several United Airlines flights recently where the seat backs had touch screen entertainment systems. I swiped my finger over a certain area below the screen to turn the screen on. Seems like the cameras in the referenced picture might be for the same purpose.

Of course, you have to trust the manufacturer and the airline to not use them for nefarious purposes.
It is absolutely famous, but its fame is somewhat cloistered. The Elephant's Foot is a gateway to the Chernobyl rabbit hole for so many people. A geological, cataclysm celebrity; a fucking rock with a documented kill count and it sits still. Fascinating.

This picture led me to reading all about Chernobyl, Pripyat, glasnost, and the collapse of the SSR in the context of logistics and energy infrastructure. The whole chibang was the result of good intentions, poor planning, and an intellectual environment experiencing a death spiral. During this process, I watched a documentary on the Chernobyl clean up effort. Chernobyl was the largest military deployment by Russia since their "Great Patriotic War."

I digress. This picture could be accurately portrayed as a perfect metaphor for the scientific endeavors of the 20th century; unique brilliance, unfettered intention, bureaucratically fettered investment, unintentional disaster, Herculean effort at recovery, and all of it flushed down the memory hole.

I'd argue that top bay area tech companies are recruiting CS degree holders at higher rates than bootcamp self taught types. It may be harder for self taught types to get past the HR recruiting filter so they settle for second tier companies that are more ethical.

Also someone grinding through a rigorous CS degree might want the biggest ROI vs a self taught type that is happy to take what they can get without and still get paid well without the debt of a CS degree.

I don't think we can draw any conclusions and to state the obvious, correlation =/ causation.
Because most other EVs other than Tesla lack range, while you can still take a Volt on a long trip without having to plan around finding a special charging station.

It’s the single best solution on the market to cutting fuel usage by about 90%, being fun to drive and not having all the headaches that go with range anxiety / locating available charging stations.

The real question is why you’d by an all electric when the Volt was an option? They’re totally impractical for anything other than a 2nd car.
God has wish that conversation was recorded, I’d probably listen to it twice.
Well, thy likely ran out of some sort of subsidy or tax break and figured that on its own, it'd never make a dime.
PHEVs were such a misconceived idea. So many more parts to wear out for such little benefit.
Agreed. Their marketing push ( not sure with what actual practical purpose ) is remarkable and frankly, annoying, in daily life. Can't take a train, walk down any random street, enter any number of shops / offices / konbini / whatever, without seeing a sticker, ad, poster, clip, from one campaign or another from them.
Understood. I picked that as it's my next kind-of road trip (though I'm anticipating most time spent at the destination).

It's ~ (9 + 3) hours of actual driving, with an overnight ferry ride in the middle, btw. Anything involving a ferry or similar will complicate an algorithm, I'm sure. I'm assuming you basically ignore captive travel time in those situations?

I had not experimented with the budget constraints originally. I note that if I put in 4 days & $2000 it offers trips of 13-15 days and $3000-4400. With 4 days and $3000 budget the trips are 10-14 days and $2600-3900.

> Depending on how much you drive, two electric cars over 20 years might well be cheaper than one gasoline car lasting that long.

This might be true if it weren't for the fact that the price of a new car keeps going up as a percentage of median income rather than down.

I had two cars bought new from the late 1990's (one finally got totaled). The annual maintenance cost could be quite high (I calculated that about $4K per year would be the breakpoint) on those and it would still come in lower than the equivalent class of car (another used car doesn't reduce the maintenance much and you have a lump payment). I would have the discussion with my wife to get rid of one of them every year, and every year we would come to the same conclusion--replace them when they die and not before.

Now, some of this is dependent upon whether your car is your sole source of transportation and whether you can cope with your car breaking down (money, time, etc.). It was no big deal for me to lose a car and put it in the shop--someone else will have a different reliability calculation.
i often wonder if communities moved away from living on top of streams (and other areas where pooled water was common), this would prevent a large proportion of infection.

If there is no water there are no mosquitos..

while the distance a mosquito can travel away from a water source is anything from 300 feet to 100 miles depending on species the majority cant get further than a 3 to five miles.

I could not find anywhere that stated how far the malaria spreading Anopheles mosquito can travel i believe it is less than 4 miles.

I also understand they need human blood, so whole populations of this mosquito could be wiped out just by moving away from water sources.

Of course water would then need to be collected and stored in closed systems at communities etc etc

As a child i lived in a country town and regular council checks of pooled water (including septic systems) were eliminated and/or treated and I dont remember one incident of been bitten by a mosquito as a child while living there.

Only since moving to the city as an adult did we have a mosquito problem
Humans have been murdering and raping each other for centuries.
If you've been using Vue for some time this should be obvious...
A car’s lifespan is somewhat probabilistic, so if the average is only ten years then there’s a decent chance of a maintenance catastrophe well before that. People don’t like to make that sort of gamble.

That said, I have no idea why the other commenter thinks current EVs are five-year cars. My Model S is four years old and drives like new. I see no reason it won’t last just as long as a conventional car.
Because you’d buy a Prius (a wildly successful vehicle) instead of a PHEV (and still realize a drastic reduction in gasoline usage over the life of the vehicle, while still realizing a high level of reliability). There is a reason the Prius was often put into service as a taxi.

I’ve driven my Tesla from the west coast to the east coast with minimal hassle (using only Superchargers), and with newer EVs having longer range and fast charging stations being deployed rapidly (Electrify America), I argue that the idea that an all electric vehicle is impractical except as a second vehicle is an antiquated notion.
This is a nothing article.

The article provides no meaningful analysis. Here’s what might have made it worth reading:

* How does the hardware, and software like the kernel, manage heat in the machine?

* Some information about CPU power states, &c, and how the kernel interacts with the hardware regarding them.

* Some analysis of how Activity Monitor works and why it ascribes a certain amount of CPU activity to kernel_task, or to any other task.

Sorry, but in Windows, Mac and Linux x86 docker is a huge part of my workflow...

Maybe they got negative commissions or couldn’t gouge on maintenance.

This a thousand times. All the best languages have a good way to print out a structure, and allow interactive inspection. Instead with C and C++ we have to suffer with debuggers rather than just using good old print statements.
This is true, but a huge part of that is VMs with linux or windows, and for me x86 docker workflows that go to x86 servers. It'll be years for any real transition imho.

It took 4 years of concerted effort to get most node things working right in windows.

Aside from oil changes and tires, the only real maintenance needed was to top off the battery coolant once. (And that was due to a known manufacturing defect in my batch - fixed under warranty, flawless since.)

You are both sort of correct. A foreign built ship can be us flagged, it just isn’t eligible for Jones act trade. I am a US Merchant Mariner who has worked on a US flagged, Australian built ship in Asia. There aware other considerations besides just cabotage laws about where one might want to flag one’s vessel.

The one thing I never understood was why everyone gets bent out of shape over shipping rules but don’t consider or care about airline cabotage.
One would think that after nearly three decades of internet we’d all have agreed on this. It’s not ‘your’ feed, it is content you posted on a public forum. If you want to monetize it, find an audience and sell them your content in private, or generate revenue from the exposure.

If you absolutely must use C++, I like to read Bjarne's A tour of C++ which gives you a very high level overview of what has changed, and then deep dive with Google if there's something worth digging into. The reality of a language as large as C++ is that each project will only use a small subset of the language and libraries, and the nature of object oriented programming leads to vastly different architectures for similar problems.

If you can, I would learn Rust instead. Rust is a much smaller language that purposely limits the way you use the language to encourage particularly safe practices, and tends to favor designs that are hierarchical instead of allowing hairball object graphs. Rust also guides you at the compiler level in ways that C++ programmers must learn to do by heart, or simply leak memory and create nasty patterns in their code.
I guess resource allocation would be under utilized, but being able to respond to web requests allows for a single lambda to execute for any number of different requests. For example we had a client who wanted a SOAP service to interface with our system, so instead of creating a WCF service or something and hosting it in IIS, we used SoapCore which is just middleware for accepting a soap action or sending the wsdl information back. So we have a small lambda (it's like 500kb) in a Lambda accepting ~1-10 requests during monday-friday for this client. And since Lambda only charges for duration of execution time it ends up costing nothing as it falls into the free tier. So even if the resources are underutilized I don't see an issue. (sorry for wall of text I'm on my phone)

C++ does remove deprecated features, but so far there has been no reason to deprecate OOP.
The fundamentalist viewpoint you're espousing is not particularly convincing; in particular, the amount of labor required to kill and replace working systems for aesthetic reasons (as opposed to evolving them) would remove much of the free time required to create new and innovative technology.
> I absolutely loathe Twitter threads

I love Twitter threads because if they’re done right (which is a big if, admittedly) then they’re equivalent to an annotatable essay: each fragment of the thread can be replied to individually.

The difference between this and a traditional annotation platform is that Twitter forces the author to choose the granularity of the annotations, rather than leaving it up to the annotators. (Unfortunately, a lot of people do a bad job choosing this granularity, probably because they don’t realize this is what they’re doing.) Also, since the replies are themselves tweets, the system has a fractal form, with the annotations themselves being annotatable.

The number one rule of writing Twitter threads: do not split sentences between Tweets. Hopefully one day this rule will be widely known and followed.
I’m impressed with companies putting batteries in cars today. Moonshots are nice, daily vehicle deliveries is what destroys oil demand.
This is sort of incorrect, it is possible to flag a foreign built ship under the American flag, it just isn’t eligible for Jones Act trade. There are a few reasons why a company might want to do this but for the most part, companies will choose a flag of connivence over American flag if they can sail between US ports anyways.
