It is true. Have an example load of pictures: https://duckduckgo.com/?q=street+light+electric+car+charging.... My city (not London!) has had them for >3 years that I remember.

The main difference is that (a) each street light is actually ~ 10W, and (b) the wiring is massively over-specified. Quoting from a local authority source for street lights, [1], the minimum conductor area allowed (for the 220-270 VAC supply) is 6 mm^2, for a total thermal current limit of around ~55A. If you have, say, 100 lamps on a single "ring main", you still only have a power draw of ~1 kW, where the cable is rated to 55 V x 220 A ≈12.1 kW minimum.

Honestly, hybrids are a quicker win.

IMHO if governments want to meet their Paris Accord targets they should be focusing subsidies on getting the price of hybrids down to the level of the same model as a non-hybrid.

Reduces emissions in traffic and lights and helps build out charging infrastructure with plug-ins without an "over" reliance on stations.

Certainly also encourage BEVs, but I think an easy-is stepping stone is a needed given climate change.
Reuse of glass bottles is not recycling (it's reuse.) And there is no problem, it works great.
I think it was a mistake to tell juniors everywhere that they blogging and personal brand building were career hacks. Too many people are churning out low quality content because they think it will give them a career or hiring advantage.

These days, many of the best programming tutorials can be found by going straight to the source documentation. Many popular projects and vendors are providing volumes of useful examples to get people started. Beyond that, many of the companies offering low-cost training courses are significantly better than what random people are offering on the open internet.

That said, your platform suggestion feels overly complicated. The more complicated the platform, the more the tutorials become the centerpiece of the experience rather than the code itself. In an ideal world, users would allocate as much mental energy as possible to the code and learning, without being bogged down by dealing with the tutorial platform.

A platform that is self-hosted by random people across the internet with tutorials that are cloned, forked, versioned, and modified across different websites sounds like a step in the wrong direction. In an ideal world, beginners would be able to get started on a good tutorial right away. If they instead have to sift through endless Google listings of slightly modified, forked tutorials while I search for the most updated or "best" fork, they're going to waste all of their energy on the tutorial process.

In a perfect world, the best tutorials would be mated as closely as possible to the source project documentation. Keep it simple and obvious.
Multivariable calculus, differential equations, linear algebra, probability theory, statistics.
Yes, this matches my experience. I've been doing Rails full-time for about 6 years and any "slowness" has been the result of some problem, not Rails itself. 99% of the time this is an uncached n+1 query situation, or some beastly slow database operation that needs to be moved to background processing, things that would be problems in any framework or even some sort of bare-metal asm solution that nonetheless relies upon an external storage layer. =)

In a CRUD app the Rails layer should be extremely thin and the storage layer(s) should be doing nearly all of the heavy lifting.

There is a level of traffic at which even a "properly" thin Rails layer becomes the bottleneck, relative to many other frameworks.

TechEmpower benchmarks suggest it is around 2,500 requests per second in their "multiple queries" benchmark. In a more real-world scenario that might be 1,000 req/sec or less.

https://www.techempower.com/benchmarks/#section=data-r19&hw=...

If one is attempting to serve more requests than this per minute then yes, perhaps Rails is the bottleneck. Admittedly, Rails' large memory consumption relative to other frameworks means it can be tough (well, technically easy, but expensive) to scale horizontally at this point.
I think it would be good to add in the graph the threshold of 200 beds in hospital. It is in the text, but it would be good to see it in the graphics.

> 3% of people are destined to die due to their genetics

Hopefully, 3% is too high. In some places that had huge waves of infection, the dead rate is like 0.1% but nobody know the total number of infected persons, so we will not know the total death rate until the last wave. I hope it is like 0.1% anyway.

I don't like "genetics" in this sentence, because there are too many factors, like age, weight, nutrition, ... Probably a part is just genetics, but it is probably just one of the factors.

(If someone had a bad car accident 5 years ago, and the doctors had to remove one of the lungs, the chances of dying are probably higher [citation needed], and it is not related to any genetic background.)

More in general, the number of asymptomatic is still not very well known.
Provision differs by local authority, but there are some areas of London where they appear to have put a plug on almost every streetlight.

I hate Facebook and Twitter as much as anyone but it generally takes saying some crazy stuff to get blocked on Twitter or Facebook. Now they suddenly have a social network for their cult where Donald Trump is their leader and is somehow taking down the deep state and will uncover massive voter fraud while simultaneously getting hundreds of thousands of votes thrown out making him the winner and using martial law to mass arrests all the Democrats for operating undeground pedo rings in pizza shops. Do I have that right?
> Used cars, which were on the road before April 2017 and produce low levels of carbon dioxide emissions (the limit is 100g/km CO2 or less), continue to be taxed under the old system and retain their tax-free status, whether powered by petrol, diesel or electricity.

The UK is making sensible small steps. That quoted rule has ended and now only electric cars are exempt from that tax. We’ve had high fuel taxes for a while, though frozen lately for poor reasons, rather than the planned increases.

95% of BEV charging happens at home.

Presently happens at home - for those with off-street parking. Plugging in and charging overnight makes a lot of sense for those that a) do have that and b) don't do long enough trips to need to charge elsewhere. But that leaves out an awful lot of people. And EV ranges aren't nearly as long as the manufacturers quote* in any but ideal conditions with a single occupant and no luggage. So filling stations will still be needed and they will all need superchargers.

* Yes neither are ICE's but this isn't a problem for anyone because there are petrol stations everywhere
I have no strong opinions on this other than that it's inevitable at some point. However, a theory:

Many of the HN crowd here are quite likely to live in an urban area, in an appartment without a fixed parking space. There is no 'charging at home'. Sure there're a decent number of plugs around - but for _everyone_? Not by a long shot. What this law is basically saying is that there will be no practical way for these people to own a car - not least without significant infrastructure work and public investment (and corresponding political will), which is, not always something you want to bet on. Given the healthy dose of skepticisim anyway - I'm not entirely surprised this is being received with less than universal excitement.
Yeah, just wait till the mass has to use it too instead of 2% of the people. No issue there...
5 minutes in addition to the normal time you get when flying a wingsuit would feel like forever. Even 2 minutes (my average) starts to feel strange towards the end after being used to a typical 60 second skydive.
Significantly smaller than Twitter of course but big enough to have a pretty good direct idea of sizes of various teams that are needed and also indirectly when working with larger apps of others. And for completeness I’ll admit that it was 3+ years ago. Twitter is not exactly going through explosive growth either.
I'm all in favour but would quite like to know how much spare generating and grid capacity we have, and what the demand will be if all cars go electric. I get the impression we're not building new power stations fast enough but would like to know more.
Fully agree. The problem gets even worse at bigger orgs where there's a separate, security oriented, team which is responsible for setting/managing IAM roles and KMS keys. I think the AWS ecosystem can be very discouraging for younger engineers in these situations. A innovative PoC in your downtime seems a lot more daunting when you need to learn about 4-5 AWS services that are unrelated to code execution and you have make a request to devops for a new IAM role just to locally test out a prototype that you built over the weekend.

You're right that the user experience is a huge blocker, but I think that's something we as authors of tools can improve on. For example, there's a Wordpress plugin that lets your Wordpress site act as an IndieAuth identity[1]. That makes it pretty usable from and end-user perspective.

The challenge with centralized is that it is a single point of failure. The original post was more focused on "If you get locked out of google, you get locked out of everything". In that vein if promise gets hacked/bought/abandoned/changes it's business model etc.. then you lose all your accounts. The anonymous nature of it is great, but this is something Apple already offers with their sign-in with apple which is already widely supported and with the proxy-email solution you can still be contacted by the sites you're signing up with.

I got interested in IndieAuth because of a project of mine[2], trying to make it really easy for everyone to self-host their facebook/twitter equivalent with direct control over who has access. This runs into the problem with wide adoption where you have a separate credential for each of your friends' blogs. With IndieAuth built into the self-hosted platform, then your own self-hosted site becomes the one credential you can use on all your friends' sites. Self-hosted distributed identity for privacy AND ease-of-use.

Presumably this would be solved with time-based energy pricing to incentivise people to use electricity at times with lower load (which is often at night: perfect for EVs)
>Oh sure, it's not hard at all when compared to something really hard!

I guess the point is that it's not as hard as many people make it seem. I switched from Sublime Text to vim and in a matter of one or two days I felt comfortable editing text with it and in contrast to other editors the learning curve quickly flattened, because you're actually learning a rather simplistic language with grammar and a small vocabulary, instead of memorizing key sequences which most of the time don't follow any logic.

> No they speak German because that's the easiest option for communicating with other people. Vim is not the easiest option for text editing.

What is the easiest option then? And I'm not talking about the easiest option during the first week, but afterwards (i.e. the majority of time).
I'm curious what you're referring to specifically, since there is incredibly sharp film footage out there.

Are you talking about resolution from film grain? Because 35mm film is generally to be considered a good bit higher resolution than 4K.

Or the noise properties of film grain, which is a separate issue from resolution? Which shows up some in well-lit conditions, but is even more obvious in nighttime shots? That's certainly easy to add.

Or are you talking about lower-quality lenses (e.g. chromatic abberation), or focus issues?

Or something else? I don't know at all what you mean by the "aliasing and sharpening" that you claim professional digital cameras perform. (Since we're not talking about iPhone camera processing, but rather the cameras movies and broadcasters use.)
I live in the UK and I'm 100% for it in theory, but 100% against it in practice.

I currently have an electric vehicle - the only kind of usage scenario where it works and is absolutely brilliant is charging at home. That's about it. Public charging is a joke, vast majority of stations either don't work, are occupied most of the time, or cost so much money to use that it would literally be cheaper to drive a diesel car.

We visited our friends some time ago in London for a few days(before lockdown). They live in an apartment so no way I could run a cable to the parking space. No problem I thought - there's a Shell station nearby with a charging point, several ChargeYourCar points at car park not far away, and I could see on ZapMap that there were two charging points on the street - and worst case scenario there are rapid chargers along the way at few motorway stops.

We got there and basically - all ChargeYourCar points were out of order for 3 days we were there, the 2 charging points on the street were only for permit holders(something that ZapMap didn't mention), and the one single charging point at the Shell station nearby was occupied every single time I checked. So we stopped at the motorway services in the end, where they had 4 rapid charging points - all taken. We waited 30 minutes for someone to leave, once they left the car wouldn't connect - had to ring up the number on the charger, finally the customer service advisor restarted the point for me and it started charging. Only another 45 minutes of waiting and we had enough charge to get home. Oh and the charge was literally £0.49/kWh(I pay £0.05/kWh at home on a night tariff) - I had a Qashqai 1.6dCi few years ago that I could fill up for that much and drive down to london and back.

Again, the car itself is brilliant. It is the future. I have no idea how people still drive around in cars that burn anything to move - they are loud, having to have gears is stupid, having to keep buying fuel is stupid.

And yet.

I can't imagine that the UK government and the private sector will get their act together and somehow, in 9 years, the infrastructure will be amazing, and they will find answers to questions like how do you charge at an apartment or a house with no dedicated parking space. I'm eagerly awaiting to hear about these solutions.

Just because deniability is a non-goal for them doesn't mean we can't add it into a variant of MLS in the future.

The Signal Protocol achieved deniability by using a three-way Diffie-Hellman handshake instead of digital signatures: https://signal.org/docs/specifications/x3dh/#deniability

I think we can do something similar. The Matrix folks are already working on a decentralized MLS, after all.

Thinking about it, I agree that forking might not be a desirable feature. But giving an option for people to host the platform on their own website is a prevention that the tutorials will get deleted just because the platform says so.

Maybe the "platform" should be embeddable so you can have it as part of your documentation, for example.
Are you saying you would hit the physical switch and it wouldn't activate? I don't think I've ever experienced that.

Early on, I would have command failures when the dimmers were powerline only, but with the dual band ones (RF mesh + powerline) that they have been selling for the last 5+ years I don't think I've ever had an error.
Yeah those are solutions, I'm just struggling to imagine that infrastructure being built in time to not be a major inconvenience. Unless it is built I could see the attraction of not wanting an electric car in 2030.
True. I checked a better route planner, a great app to plan electric vehicles trips, and driving from Brighton to Glasgow today in 2020 is 7h10m of driving and 36m of charging with a tesla model 3. Let's round up to 1h of charging. I don't think it is a problem today, and even less in 10 years with better cars and a bigger charging network. Sure you may lose some time because you will have slightly longer breaks, but it's fine in my opinion and don't forget that electricity is cheaper than gaz (unless you charge to 100% on Ionity without using a car from a Ionity constructor).

A lot of people are saying to leverage your agriculture PhD, but I don't see people asking if you like agriculture. Is the interest in data science because you want to get far away from agriculture, or just concern that there isn't much future in it?
What caused confusion is that you put “written in ~250 lines of idiomatic Python code” in the readme file and didn't mention anywhere that you were in fact using a bunch of C libraries to do the heavy work.

The disclaimer section (which contains this information) was added 44 minutes ago. And it's still misleading. For example about hiredis you write:

> Python extension that wraps protocol parsing code in hiredis.

Where is the mention that the parsing code is actually C code?

The demand for second hand cars is already there. In 2030 people aren't going to turn around and say "wow hmm I all of a sudden want a second hand combustion engine car" and find themselves priced out. The first people to be priced out will be the price who buy cars 2-3 years old and drive them until they need a major repair. Realistically, there's 20 years before the full impact of this policy will be felt at the bottom of the used car market, and the "poor" (who are a large group) will be hit by this law. That means there is 20 years to come up with an incentive or a solve.
