I think the problem is not going to be the technology, but the business model.

Electric vehicles as a financial proposition make much less sense when the cost becomes "and a $XXX dollar per month battery swap plan for as long as you plan on owning this vehicle". It also becomes problematic since batteries are the most depreciating major component on the vehicle. If you have a model where I can opt in to have my battery swapped for a brand new one without paying for the entire cost of the new battery, that business will not be solvent for very long.

Then there's the disposal/recycling costs. It's still not profitable to recycle the type of batteries we are putting in vehicles, so unless the government is implementing a new EV vehicle tax to help offset the recycling effort, any business model would have to account for that huge cost.
I've had GPs and consultants alike google all sorts of things (even opioid conversion charts)... I have to say, I don't like it! I know they can't know everything, but quite often it feels like it's something they should know, or at the very least have a trusted source/calculator bookmarked for.
> Force each company to offer two plans (legally): one free + (ads / tracking), one premium (no ads / no tracking), then see how much people care about their data.

I like this idea but only if you force companies to price the non-free version no higher than the actual monetary value of the data they collect. Otherwise you'll have Gmail's "We'll stop reading your private emails" plan priced at 100,000 a month. I don't want to create a situation where only the ultra wealthy can protect their right to privacy.
For a brief time in 2008, 1 Zimbabwe dollar was very roughly equivalent to one TRILLIONTH of a United State penny. So technically a value of “1” did exist, but it was meaningless. I have some of the 100 Trillion Dollar notes from Zimbabwe from that time period.

How often do you folks make a 400 mile trip to LA?

I did a 250 mile trip from Bay Area to Central Valley. Stopped for 20 minutes on way back in Coalinga to add 80 miles of range at 400 miles of charging per hour.

That's a good point, and bootstrapped businesses (in the US at least) are generally incorporated in a manner that protects personal assets, so the provider would not even be able to go after the owner's house in most cases.

Disclaimer: I work at AWS, but this post isn't being made in any sort of official capacity, I have no relation to the team in question (this is the first I've even heard of the service), and the opinions here are entirely my own and not necessarily a reflection of that of my employer.

> I wonder what kind of future this spells for quantum computing - will it continue to spread or will it be limited/stunted by being controlled by only the few?

I feel like this is a step in the right direction, though. Right now using quantum computers is totally outside of the realm of possibility for the vast majority of people - they're simply too expensive in materials cost, expertise to create, conditions for operation, etc. etc. etc. - without services like this one. The only chance an "everyday" person has to try out a quantum computer is to rent time on someone's else's.

I don't think at a similar point in the life of classical computers we had options like this that were readily available - you could rent time on the computers, but I can't imagine that getting access to them was as easy as it will be today with the internet being a thing and service providers offering high granularity on billing.

My understanding (and I'm not even remotely an expert, so I could be totally off base here!) is that it's an open question on whether or not quantum computing will ever even be doable in environments where classical computing works - it might not be within the realm of what physics allows for it ever to be possible to have a quantum computer powered smartphone.

I hope access is ubiquitous someday for people, but in general I feel like this is a good step while that's not practical.
It will be interesting to see what wins out. I'm personally not optimistic that battery technology will get much better from a charging perspective than it already is. But that would be fine in my book too, if we reduced that to ~5 minutes. Anything longer feels like a regression compared to fossil fuels.

W/r/t standardization - yeah, mechanically there might be some interesting considerations like mounting points and common interfaces on the bottom of a car; but if the will is there, I'm sure there is a way.

Bad battery swapping isn't hard to discourage - if you poison the well, your vehicle is banned from the subscription battery program and you get to charge at home. Many ways a car can be tracked by the battery swapping station - especially if you have to sign in with your Tesla account/use an app to initiate the swap).

Well, it's not just a display issue. In accounting, associativity and commutativity are important. People do care that `a + b + c - a == c + b` should evaluate to “true”.
Given Tesla charges for use of Super Chargers now and the cost of electricity dominates build out cost, they should be able to build out enough infrastructure in a cost neutral way to stay ahead of the curve.

I've found that getting involved in some type of group activity is super helpful for that.

I'm into music, so I joined our local community choir. It's not necessarily the style of music I listen to on my own or like to play/perform (I'm more into guitar and folk music), but its a very social activity that gets me out of the house once a week, with people that I have some things in common. I've made some great friends and got to know a lot of people in my community that I would not have otherwise.

I really start to miss it when we're off-season (long summer break), because of that feeling you get when you haven't left the house for a week or so. :)
I think recharging is a transitory solution anyway. The real game changer will be automated battery swaps.

Battery swaps seem to have been a transitory solution. Battery forklifts and battery container shuttles at ports used to use battery swaps. But once batteries got good enough to run them all day, it was easier to just plug them in for a recharge when not in use.[1] Many electric cars can now go further without stopping than the driver can.

[1] https://www.liftway.ca/swap-your-forklift-batteries-for-the-...
Of course. But if you know you don't really own the battery, and the swapping capability is in the price it is a non-issue. We already have something similar here, in Australia, for swapping LPG/propane gas bottles. You can refill if you want ( it is often cheaper) or swap with a full one. They are all dated so they also have "use by date"

But it is correct.

> It's easy to write a program that sums up 0.01 until the result is not equal to n * 0.01.

It's not easy to do that if you use a floating point decimal type, like I recommended. For instance, using C#'s decimal, that will take you somewhere in the neighborhood of 10 to the 26 iterations. With a binary floating point number, it's less than 10.

The Cybertruck has a top end range listed of 500 miles. The solution in the end is going to be cars that last longer than the humans driving them (or the human passengers when we finally have autonomous cars), combined with ordinary charging stations in every parking location.

Battery swapping is complicated and capital intensive. It would have to solve an urgent need to catch on. But there isn't one.
NuCypher (YC S16) | Engineering Lead | San Francisco, CA & REMOTE | FULL-TIME | VISA

NuCypher is hiring an engineering lead to help build a new open-source cryptosystem leveraging post-quantum cryptography. A successful candidate does not need to have prior experience in cryptography as they will work very closely with a cryptographer to build out the system. However, they should be a quick learner and comfortable around math (e.g. linear algebra, probability, number theory).

A successful candidate will lead engineering for the new open-source cryptographic product from the ground up. They will work on problems at the forefront of cryptography and have a leadership role in design decisions of the system. As such, competency in algorithms and low-level design is a must. An interest in compilers and/or optimization would be nice to have. Given the nature of an early stage product, a successful candidate should work in a fast and iterative style when it comes to prototyping. They will be be motivated by solving tough open-ended problems. Additionally, they should be highly comfortable working in a system programming language such as C or Rust (whether through work experience or side projects).

We offer competitive compensation and a highly flexible working environment.

Responsibilities:

* Design and build the core infrastructure of a new cryptographic system (alongside a cryptographer);
* Lead the engineering side of the product;
* Implement cryptographic primitives (including zero-knowledge proofs and fully homomorphic encryption) and write robust, security-first code that will run in high-risk, adversarial environments;
* Contribute to research;
* Improve engineering standards, tooling, and processes.

Competencies:

* Proficient in a system programming language such as C or Rust (also open to those proficient in a functional programming language);
* Competency in algorithms and low-level design;
* Confidence working with multiple programming languages;
* Comfortable around math;
* Excellent communication skills and the ability to explain complex technical issues to a non-technical audience.

Bonus Points:

* Math background and/or strong interest in math;
* Background in compilers and/or optimization;
* Familiarity with applied cryptography and advanced cryptographic concepts like lattice-based cryptography and zero-knowledge proofs;
* Experience with designing and/or implementing large-scale distributed systems;
* Any experience, professional or amateur, working in security engineering, appsec, or other information security roles is a plus (hackers are welcome!).

I've had this debate on HN many times before. Look at every WHO essential medicine developed in the 21st century. All but one was developed in the US. The only one that wasn't was developed in Japan. That's just pharmaceuticals. The same plays out with other innovations in medical treatment such as medical textiles used in vascular implants or even wound care dressings as simple as Tegaderm from 3M.

> ”Current CCS specs are lacking - a 200 Amp limit”

There is no 200 Amp limit in the modern 150-350 kW CCS chargers being deployed by networks like Ionity and Electrify America.

Tesla, of course, already uses CCS in Europe. A Model 3 can charge at over 190 kW on European CCS chargers. A Porsche Taycan (800V), 270 kW.

I think there's a difference between providing a generic SDK and providing specific targeted SDK. E.g. if you made libstdc++, nobody is going to blame you for every C++ program using it. But if you made specific malware with specific exploit for a specific vulnerability, and people use it to take over other systems, you may share the blame - even if you yourself never used it. In the latter case, you'd be known as "malware vendor" and your trust profile would be set accordingly. I think this is close to the case for Kape. They targeted specific market with specific product. Now, it's completely their right, nothing illegal, but as well it is my right to stay away from people who are into certain markets and certain business models.
I keep coming back to wanting range types in C ala Ada. And if something screwy happens you get a seg fault.

type packet_buf_size is range min_packet_buf_size to max_packet_buf_size;

packet_buf_size = 10222034440; // this causes a seg fault
So that when somebody disagrees with this, they can go with the classic "So you support self-harm and suicide?".
I imagine a semi trailer rigged with a battery, grid connection, and a set of chargers for seasonal surges. Maybe even a deployable solar panel array, but I suspect the PV panel would be too constrained to be much more than a show piece.
Not that hard. Unless there is no physical space to add more capacity.

How about people who are an utter nuisance on their neighbours? Do we just say tough luck to the neighbours?

People who have zero respect for their neighbours and just do whatever they want at whatever time they want?

How many noise complaints will the neighbours be forced to tolerate because I have zero doubt given SF's governance that putting these people in jail will not happen.

Should people just tolerate their lives being disrupted until all avenues of addiction/mental health/other treatment are exhausted?

Small correction - I don't think building adware - as long as it's not hidden, not doing clickfraud, etc. - is necessarily dishonest. It's just not the business which you want to be owning your VPN. Just as cheap used car dealership is not necessarily dishonest, but that's probably not where you want to get your banking or medical service.
> Binary floats are unable to represent 1/10 just as decimal floats are unable to represent 1/3.

That is true, but most humans in this world expect 0.1 to be represented exactly but would not require 1/3 to be represented exactly. Because they are used to the quirks of the decimal point (and not of the binary point).

This is a social problem, not a technical one.
I'd say it's the latter. The selfie obsession is all about curating how you present yourself and your lifestyle. No one would want an IG or Facebook account with someone else at the helm.

I've been switching to DDG as well and I haven't noticed my life change in any measurable way. You might be right and my results may have been better using Google, but I am willing to make that sacrifice in order to participate in a world I prefer.

I suppose I consider it like this, Google's results might also be better if they didn't show me so much spam. I don't know. My life isn't that much improved due to them. I don't know what I don't know.

I'm okay not having a 10% faster car as well. I'm okay with that. I'm willing to drive a slower car to save the environment. I'm willing to make that personal decision for what I think will be a better internet too.

We can't constantly say, what's best for me, what's best for me without expecting that everyone on the planet doing that will never lead to a planet that's best for all of us. My search results might be 10 or 20 or even 30%, without Google, but the world is better without Google, IMO.
Right, and there are lots of VPNs.

So why use one with anything iffy about it?

However, I gotta say that it's complicated for PIA. There's past evidence of being unable to produce logs for criminal investigators. And now there's the purchase by a firm with an iffy reputation.

However, there's the possibility that said firm was exploited by malware pushers, and not intentionally pushing malware. But still, that's evidence of incompetence, which is also not a good thing for a VPN provider.

And then the CEO's association with Israeli intelligence.

So anyway, it is complicated. But it seems most prudent to wait and see.
