I would like to take that vision of the future you mention and add to it the concept of vertically stacking the fast-charging cars two or three vehicles high to double/triple your customer density. When you picture it mentally you can begin to see the financials start to make sense. If the underground fuel tanks can be properly decontaminated and repurposed as storage for uhhm storage batteries you have maximised your revenue generating space.

Being able to supply the “Ooomph” to fast charge 6 or 10 cars with a 5 minute vehicle turn around ( a la Tesla’s fast chargers) but also triple stacked with cars (hydraulic ramps, customer disembarks and uses the time to pay or shop). Chuck in the ‘free' storage space for your ballasting batteries and I can see a great market for buying up old gas stations located in inner city areas - especially those that are currently car washes, vacant lots etc.
It is. Note that OP wasn't criticized for the statement per se, but that PP suggested an amendment to that statement.

It must be equally OK to amend incomplete statements, otherwise we stagnate.

The primary targets for nukes aren't cities, they're other nukes. Most of these warheads are set for groundburst (or underground burst - I remember a bunch of research in the 80s about burrowing/penetrating warheads), because to blow up a 3-4 foot thick reinforced concrete silo you basically need to land right on top of it. That's the big fallout threat.
In the same vein, I'm blown away what we can do with xray crystallography these days! Structures of proteins with hundreds of atoms can somehow be deduced from some tiny light spots in a kaleidoscope picture? Magical.
Well, I'd welcome the idea of once a year total shutdown for a couple weeks: no cars, no economic activity, except maybe hospitals and other infra. That would be a sort of worldwide retreat. I still remember how clean the air felt the first time the us did a hard shutdown (empty roads, people were scared). I'm sure the capitalists will hate the idea to halt the factory for 2 out of 52 weeks.
>charge the end customer in some larger amount - say $5 or $10, and then draw down the micro transaction amount as you go.

Wow, I just realized why Steam does this for in-game purchases.
I'm not saying being regional is the problem, but that we have an opportunity to question the definitions/assumptions behind "regional". A lot of our country's ideals of a representative district stem from concepts/assumptions that a representative's office should be no more than a brief horse ride away. Gerrymandering has insured that isn't the case in a lot of places today hence the assertion that the original ideals are unmet ("broken").

But what happens if we question the assumption directly? Is it okay to take public transportation into account? What about car travel? To get into useful extremes for illustrative purposes, what about air travel? How far in travel time is feasible/allowable, an hour's distance? Four or more, like some of the classic representative horse "ridings"?

It doesn't entirely matter where you stand with specifics to those travel methods/distance qualifiers: the point is that those are variables/knobs in the equation. If the outcome is better representation overall, knowing that your representative is less than four hours by car away, for instance, may still be sufficient to meet the useful parts of the "regional" ideal while providing more options to explore in optimizing representation (such as random sampling or some k-means clustering gradient) than the traditional "geographies need to be contiguous and no more than a simple horse ride big".

Technology also presents other opportunities to explore: Would you be happy if your Representative's "Office" was a Discord server of "the right size" (say, small enough that it isn't a cacophony, big enough that it isn't just in jokes and memes of two to three shitposters every day) and your Representative had mandated "Office hours" to "hang out/townhall" in a voice or video chat channel? I know that a lot of people might find the idea ugly or terrifying, but I find it an interesting ideal of a different more modern sort. You might feel more likely that your voice is directly heard, and a good Discord server can feel very "regional" even when the actual participants are scattered to the winds geographically. I'm not saying "Discord but for Politics" is necessarily the best idea either, just that it is a useful thought experiment in questioning what it means to be "regional" in 2021.
I actually agree with decriminalizing drugs, but I think they should be controlled like any other prescriptions or like weed is currently controlled. Specifically portion controlled so that drug does not destroy person's life. I have experimented meth and many other drugs. Mind that if you haven't done meth and you try to compare it to some other drug like alcohol then you are just ignorant. I have to say that it's easy to get lost in meth and a lot of people don't have mental will(or maybe capacity) to get out of the drug and hence I have to say that this type of thing does need to be controlled in some manner.
>Does it download the entire history of all transactions and replays them into the local database?

This is what clients do initially, until the database grows in size. Every time the transaction log increases 50 KB, the client takes a snapshot of the database's state at a particular point in time, compresses and encrypts it, and uploads this state to the server. We call this a "bundle". This way when clients reopen a database, they load from the bundle first, and then apply any new transactions that come after it. Rather than needing to query for the history of all transactions and decrypting them individually and reapplying.

>Hot do concurrent modification get resolved (several clients try to modify the shared stage at the same time)?

The server assigns each transaction a distinct sequence number via an atomic operation. So clients always apply transactions with the same distinct sequence number, in sequential order. The client relies on this to enforce uniqueness and versioning. Only the lowest sequence number itemId gets applied to a database if 2 clients insert with the same itemId at the same time, and similarly, only the lowest sequence number version of an item gets updated or deleted if 2 clients update or delete the same item at the same time.

With regards to bundling, it's a bit more complicated and there are layers to our approach in safely handling it under high concurrency. When a client uploads a bundle, the database records what sequence number the bundling took place at so clients can use it to retrieve the latest bundle. And the server retains copies of bundles at prior sequence numbers. This way if two clients attempt to open a database right around the moment a bundling process completes (client 1 receives a bundle at lower sequence number, and client 2 receives a bundle at a higher sequence number), both clients receive the same set of transactions regardless. The server sends all transactions in the log after the bundle sequence number, so client 1 just needs to decrypt and apply more individual transactions to rebuild the state compared to client 2.

Some may find this interesting too -- we specifically test for safe concurrent behavior across 2 clients using a makeshift testing framework that opens 2 browsers at the same time and does some neat tests: https://github.com/smallbets/userbase/tree/master/test

If you clone the repo and run `npm run test:concurrency`, it will run those tests and output test results to the consoles of the 2 browsers.
Stability is not just about backward-compatibility; it also means promoting concepts/idioms which are consistent and long-lived. Django has been around for about 3 times as long as React, but has not undergone the same amount of churn that React has. If someone wrote React code in 2016 and left the scene for a couple of years, can they come back and build new React projects without significant re-training?

Regarding Django templates, I know how they work, but actually prefer building an API with Django, and connecting to that with an SPA (preferably one built with Ember since, as you can probably tell, I prefer batteries-included frameworks).

I'm really not as anti-JS as you inferred from my initial post (or as I unintentionally implied), but saying the ecosystem is not problematic makes it harder for it to get better.
Ah, codecs. The biggest PITA on Windows in the 1990s/2000s. I went through two or three different videoplayers for the sole reason they shipped with whatever was needed to open just about any format out there. Meanwhile, trying to coerce WMP to open popular video formats was an exercise in futility...
That's a terrible option for Google, because it's a clear statement that they see themselves as above national governments.

If there was a clear answer there would be no need for the class action (from consumers) against them.

I don't use a product like this but if I did I would get my dentist to set me or my kids up with Invisalign. My understanding (and it could be wrong) is that they are basically the same thing only professional rather than DIY.

Of course, if my dentist said my kids needed more traditional braces I would go that route. I try to follow the recommendation of professionals I trust.
There's two quotes related to my prior comment that I like to keep in mind, thought others might find them insightful as I did:

> There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.

That one reminds me what success even means. Simply growing myself, being slightly better today than I was yesterday is accomplishment and success in itself. When you focus on others or external achievements, you tend to get lazy in your approach to growth, you look for shortcuts, push harder than is smart, and you get anxious, nervous, stressed in a way that will slow your growth long term.

> Most people overestimate what they can do in a day, and underestimate what they can do in a month. We overestimate what we can do in a year, and underestimate what we can accomplish in a decade.

This one reminds me why you got to give yourself longer horizons to success. Success and accomplishment follow an exponential curve in my opinion, you need to keep that focus and continue to accumulate that momentum until the tipping point.
I also had phases in university where I was focused on learning and lonely, and also phases where I was partying too much and not doing as well as I could have on the tests. But after a while, my life naturally balanced out. Maybe it was the long bicycle rides where I can peacefully wonder about what I want to focus on today, but I'm not sure.

In any case, by now I've seen firsthand how little practical relevance most school and university lectures had. So I guess the first step for you should be to stop worrying too much about doing well on any given test. Chances are, being more relaxed will also help you avoid these little concentration mistakes.
Auto companies cut the orders because they anticipated falling demand[0]

>Mr Duesmann described the problems as “a crisis upon a crisis”. Demand for cars slumped for much of last year because of the coronavirus pandemic, prompting auto suppliers to cut their orders for the computer chips that manage everything from a car’s brakes and steering to its electric windows and distance sensors.

>But demand for cars jumped unexpectedly in the final three months of 2020, as buyers became more optimistic. Audi had its best quarter ever, largely because of a rebound in China.

Make it proportional to the vote. If it's 51/49, bar still gets 2. Also makes third parties feasible that way.
I work in sawmill technology. Way back in history 2x4 were cut to 2" x 4". In a modern sawmill 2x4s are never cut to 2" x 4". They are cut to a thickness and width such that given saw deviation, and variable drying shrinkage nearly all boards will cleanly plane down to 1.5" x 3.5". The exact target dimensions will depend on how well the mill can control their saw deviations and the statistical range of shrinkage they expect for the wood they are cutting. Reducing dimension targets by controlling saw deviation and understanding drying shrinkage is a big part of sawmill efficiency and profitability.
How are miners incentivized to maintain the network?
As a consumer, I don't want to do this because I don't want to pull out my credit card to pay $0.01. I think they're hard to make work on a small scale. So an aggregate of people say putting $10 into a news pool, and each paying $.01 cent to read, and the news pool paying the providers, might make more sense. The micropayment could be like "credits", and may be refunded.

Qt is more like gtk rather than glib. Although it does come with a fantastic core library.

But if you can move to C++, the standard library already offers great replacements for most glib features. Glib exists mostly because the C standard library is lacking in many aspects.

> Any constraints we put in the defining consciousness and life seems to be just some arbitrary constraint put there for our own convenience.

The definition of consciousness is very much tied to how humans (or some scientists) perceive consciousness. I'm pretty sure my dog is conscious of itself and its surrounding. It just happens to have a less sophisticated consciousness than the one I have. Some animals might have a pretty high consciousness but they fail to communicate it to the humans.

You could make a similar argument about... any video, song, essay, etc, created by anyone. So I’m not sure what the point of your comment is. I think you are getting at the fact that there’s a lot of bad-faith grifters out there who prey on entry-level devs. This is a legitimate concern! But in my experience it’s pretty easy to sniff those folks out with a superficial investigation. You don’t want to “spend any time” watching the video but I think you can spend two minutes skimming their other work, their CV, etc.

I myself didn’t know anything about this person so I poked through their blog a bit. They are clearly marketing their education business (and I am not their target audience) but also seem to know what they’re talking about. More to the point: their material appears to be sincerely helpful to intermediate (and even advanced) NET devs. This relatively short post on unsafe array access in C#[1] although not especially deep, does at least dive into the runtime / IL internals enough to give a clear picture of what the unsafe code is actually doing.

I haven’t watched the video either but they are creating good-faith tutorials, they are obviously capable of understanding the .NET GC, and there’s no reason to suspect they would change type and BS their way through a new video series.

This is the case, actually. It's just this article is talking about chip production at the bleeding edge instead of the pedestrian chips used in the bulk of electronic devices.

This submission is literally about why people aren't using some Rust framework. I add my two cents as to why that might be and then that gets called toxic and dismissive.

The parent comment's point is that the money spent on the space program was likely very highly weighted to the first years building that first rocket. So dividing by 10 because it was roughly a decade is probably underestimating the budget needed to get to the moon.

They want to do workworking or something... Honestly, that sounds quite dismissive. Hopefully your teaching offer was slightly more humble than that...

> 2. The trend today with Google

Sorry, but I think this is totally wrong.

I knew the guy who wrote the very first web crawler/search engine, and even then, the intent was to find answers, not websites.

Moreover, I don't see any limit on what google returns when you search. I just searched for "the trend with google today" and it told me there were 927,000,000 results. When I got to page 22 of those results, it told me that the rest were all very similar but gave me a link to fetch them anyway. I could get to an arbitrary Nth result.

The reality is that search engines actually are, by any historical standard "some sort of oracle that can provide answers".

And when they can't/don't, they still function as tools that provide you with links to help you explore the question more.

Recognizing whether or not you've actually found the answer (from a book, from deductive processes, from a human oracle or from a search engine) has always required critical thinking skills, and that has not changed.
> What's special about the state or state government specifically that it should get its representation separate from the people it governs?

The United States is a union of states. The people have representation at the federal level, and the state level.

> Are the state or state government's aims and objectives different from the people of the state? If so, why, and what legitimacy does it have? If not, why have it represented?

No. The people of the state are the state, not the government of the state. Again, the state gets representation because we are a union of states. And local governments get representation at the state level. There are many concerns of a people, and we have people representing those concerns at different levels of government, from local to state to federal. Otherwise we could just have a single person represent everyone.

> Why does the state get represented twice (Senate and EC) but the people only get represented once? Isn't that an imbalance?

The People are represented twice as said before (House and EC). The EC is the House + Senate. So no, it's not an imbalance.

> Because it favors your side. You'd be singing a different tune if it was the other way around.

I don't have a side. I vote for policies that I agree with, which has changed over time. Party support of certain issues has changed over time as well.

I am pretty tired, however, of people crying about foundational aspects of my country because they lost an election. I think the increasing concentration of power in the federal government is a bad idea.

> And whereas designing your own chips once meant having to make them as well, that is no longer true.

This hasn't been true for what, 15-20 years? Longer? If you had a digital design and enough cash you could have gone to one of many vendors, who in turn worked with an external fab such as TSMC (or in other cases, the fab division of the same company) to create your design. When working with a vendor like Broadcom, Agere, Toshiba, IBM, Intel, Marvel you can be entirely isolated from the physical aspects of making chips, if that's what you want. What has happened over the last few years is massive consolidation of these vendors so now the options are far more limited. It's basically just Broadcom or Marvel at the cutting edge. I don't think this goes anywhere to explain why more companies are designing their own chips but it's a more accurate description of reality.

This line of reasoning is incorrect. Unlike fossil refuelling, the vast majority of EV charging happens at home. This charging does not load public charging stations at all. Unless your needs are esoteric, you might only charge at a public charging station one out of twenty times.

Of course some homes don't have private charging easily available, but that's a different argument.
Actually I think my view on climate change is more optimistic now. The article mentioned the majority of the carbon reduction wasnt actually due to reduced demand, but rather from lowered emissions from using renewables (and more specifically the closures of coal plants). This seems like pretty good news to me. You can continue to grow and operate the economy while reducing carbon emissions to levels they need to be at by switching everything to renewables.
