It's best to think of Bezos as a hyperintelligent alien who occasionally takes a tangential interest in human affairs. Here, he is bestowing praise upon the units which permitted his ascent back to the stars. That has the effect of producing more money to do more engineering to go farther. Eventually he will return to his planet.
Yep definitely opportunities

Another obvious business model is parking lots using car batteries to balance the grid and selling their service to electricity companies. People park during the day and their battery is rented to the electricity companies for load balancing
In Spain too, at least in Salamanca. But Salamanca has been a University city since the Middle Ages, so something like that has always been a logical thing (thousands of people do an Arts/Humanities Bachelor Degree in Salamanca). You know, historians and such.
Of course it makes no sense, it's a joke.
I've been taking tabs with 100mg of caffeine and 250mg of l-theanine after lunch and I found it better than a large coffee.
Your 80% figure seems rather spurious, coming I think from extrapolating a gross simplification of some 2009 figures for much bigger motors. My vague understanding is that smaller motors are hard to get as efficient. Some things I was looking at last year suggested things keep improving and that in excess of 90% was in theory quite attainable now for such motor sizes, though in practice you probably won’t find it on the market. But I did find components that should combine to something like 85–87%. (I don’t think I wrote my findings down, or if I did it was on a device I don’t have access to at present. But a quick search shows https://outriderusa.com/pages/electric-bike-efficiency claiming a motor efficiency of 93%, which if paired with a generator of similar efficiency would yield 86.5%, assuming no transmission loss which is of course unreasonable, and assuming the efficiency stays the same at lower power levels, which is likely screamingly wrong.)

>95% for chain systems assumes good components excellently-maintained. In practice chain drives are generally somewhat less efficient, commonly more like 85–90% is what I think I read, with poorly-maintained ones often more like 65–75%. This is where an electrical drivetrain could really shine: it’ll require roughly no maintenance while maintaining its not-best-in-class-but-still-pretty-good efficiency.

These figures are all rather nebulous, and get muddied a lot further once you’re putting a battery into the mix too, trying to take the power from your feet and augment it with another 200W of power from a battery (but preferably without feeding your foot-power through the battery). Then I go from being an amateur that knows just enough to be dangerous to a rank ignoramus.

For my purposes, an electric drivetrain would probably be markedly less efficient, but if it can be enough more convenient, it could be worthwhile anyway. I also have a pet scheme in mind where you simulate 100% efficiency by adding a little more power from the battery to compensate for known losses. I feel that could fit within the intent of legislation, if only that legislation allowed electric drivetrains in the first place.
Smart. Depending on the location they might be able to just add a new stall or two with ccs poets and call it a day, and migrate the rest of the stalls more gradually.

And of course, use CCS-compatible stalls for all new builds, of which there will probably be a great many as the EV charging station land grab kicks off.
Just like they opened their patents?

> Who created that "problem we are trying to solve". It wasn't the user.

Sure it was, if you didn't want this problem you'd be fine with remaining anonymous and receiving only services that can be granted anonymously. I understand reading Hacker News doesn't require an account, and yet you've got one and are writing replies. So yes, you created the problem.

Now, Hacker News went with 1970s "password" authentication. Maybe you're good at memorising a separate long random password for each site, and so this doesn't really leak any information it's just data. Lots of users seem to provide the names of pets, favourite sports teams, cultural icons, it's a bit of a mish-mash but certainly information of a sort.

In contrast, even though you keep insisting otherwise, Security Keys don't give "escalating amounts of personal information to tech companies" but instead no information at all, just that useful answer to the question, "Are you still you?".
Countries should have anticipated things and standardized EV charging 10+ years ago. It's not only the plug size, it's also enabling me + my neighbors chargers to communicate so we can optimize load on the electric grid. Standardize amperage so that my experience as a user isn't variable. Etc.
Atlassian really needs to get it together. At my agency we're moving away from BitBucket because it has degraded so much over the past year. I was fine with the lack of features, but they've been actively making the product worse.
I think we also need to realize this is just something Elon said on Twitter with no other information. We k ow nothing about what they actually are doing yet we’re acting like they’re going to suddenly be switching to ccs.

My guess is they’re just developing an adapter.

But also… Elon time is real. Chances it happens this year pretty low.
I'm an academic. Since the pandemic began I've used Discord on multiple occasions for work -- for example, if someone runs an online conference it's common to create a Discord and encourage chat among the conference participants.

But these are all fairly informal use cases, initiated by individual academics and not by "the university".
An app shouldn’t be required. A single text message should be sufficient for payment, like M-Pesa in Kenya, or even just paying with cash like on street meters.
I used to do that a lot. Lots of small villages and soccer/football players...
I believe the way it works here (US), is most people with the standard deduction works for probably 80-90% of cases because their finances aren't complex enough or they're not doing enough where the deductions exceed the standard. So most would be fine with government just telling you what you owe/they owe and you just signing off or making a correction.

If you're doing a lot of charity donations, real estate, student loan debt, saving receipts for work related expenses, calculating depreciation on assets, etc, then its worth it, but by then you probably have a personal accountant doing it for you, not a program.
> wanting to update itself and all installed packages each time you install a new package

Whatt?? It updates itself(which you can stop by ^c and the installation proceeds without updating) which takes around a minute for me but definitely not all the packages only the dependencies.

Not sure if the parent or me has something wrong in the configuration that our experience is so different.
To me it is a huge plus. There are a lot to tell by looking at the side projects. At earlier stage start-ups, where interview process is not that rigid, it helps interviewer (at least for me) to gauge many aspect at once. Candidates love talking about their own project than anything. For me side project is a shortcut to peek into applicant's mind
What if Nike did this?
True, but as a country the US is definitely most privileged. And it really likes to abuse that privilege.
I’ll trade them. Those are my favorite for messing with gen-z cashiers.
Maybe by not framing the issue as one of 'liability' and 'surveillance', and just teaching the kid right from wrong. As for how that's accomplished, that's the parents' responsibility.

They failed here, so the state will be stepping in for the next few years.

Drawn with a graphics tablet, yeah.

I find the drawing UX of Okular very lacking - if this application could have a simple, clean annotations interface that produces clean lines with a tablet, this would be huge for me.
So I'm kind of stuck thinking, if you want to have cross-cutting changes happening in many small steps rather than one big one, why not choose a repository layout that makes it the path of least resistance, rather than one that makes it require extra effort?
I actually think you proved his point because neither iPhone or Tesla are status symbols anymore. I see so many of them they are becoming mundane. I own an iPhone and could care less about the next iteration, I'll replace my iPhone when needed.

The next model of iPhone or Tesla no longer excite me, they are just a new standard of electric car, I'm not impressed by anyone who owns either like I would be if I saw a McLaren or something roll up. Well, not that I'm impressed per say, but I'm not turning heads for a Tesla like back when they first came out, but I'll always check out a super car.

> On the contrary, you may find that you are shipping software that is so good you begin to see the value.

You may also find that when you finally do ship, everyone had started using your competitor, or that your customers needed something slightly different, or that the cost of waiting for you was so high it would have been better having something early.

I have great respect for formal verified software, I have even touched on it a bit during my PhD, and there are definitely places for where it makes sense. Same for formal methods in general. But there are other software tasks where it is not just 'not needed' but it is actually the wrong choice. It depends a lot on the opportunity cost of delivering later, and on how well defined the tasks are, and how preffesional the customer is. And the tasks where less formal methods are the right way are not "playing games", they are solving the problem under a different set of constrains, also doing software engineering.

Tesla has invested over $600 million in their Supercharger network globally [1], and should be compensated if legacy automakers want access to it for their customers. If they don't desire access to it, they can foot the bill themselves. No sense in giving a free ride to apathetic automakers who had to be dragged to build EVs. If governments want to cut a check to open up access, compensating Tesla for their capex costs, that's fine too.

For me, it’s also because of IDE tooling. Nim syntax supports so many different call styles that when you press dot for autocomplete you always see so many options to the point it’s not helpful anymore. I’d love to know if there’s a way around that issue.
When they bought the company that now makes what they sell as Bitbucket On Premises, they should have literally thrown away their cloud offering, and just offered that... in the cloud.

This years long process of badly re-implementing bitbucket on prem into the cloud, feature by feature, while the rest of the world evolves passed what they bought years ago is absurd.
Idk how you go from free-market supporters think X to "free market supporters believe climate change isn't real".

First, I'm a free market supporter. So are you. You like buying stuff, and think companies should exist and all that right? And you believe in climate change, right?

Second, most often the more zealous free market supporters don't tend to think that climate change isn't real but that the solution lies in market solutions instead of government intervention. Personally, I disagree, but I don't think it's fair to just assert that people like me don't "believe in climate change" by supporting free markets.

You're typing this on HackerNews, a forum hosted by YCombinator which is the most capitalist and free-market type of organization that exists!
I appreciate your sentiment. At the same time, looking at side projects runs the risk of discriminating against qualified candidates who don't have time for side projects because of other commitments (e.g. childcare or care for elderly relatives) or who choose to pursue non-IT hobbies to keep a work-life balance. How do you avoid treating such candidates unfairly?
Tesla is currently at 250kw with the v3 superchargers, but it's been said they can handle more and are about to be software upgraded to 300kw. A v2 supercharger is capable of 150kw.

Electrify America's are supposedly capable of 350kw but there isn't really an EV in existence yet that can hit it.
Why every successful product has to be bloatware?
All memory access in Java goes through fields or array offsets.

There are runtime checks around class structure that ensure that a field load cannot actually read some unexpected portion of memory.

There are runtime checks that ensure that you cannot read through a field on a deallocated object, even when using weakreference and therefore triggering a GC even while the program has access to that field.

There are runtime checks around array reads that ensure that you cannot access memory outside of the allocated bounds of the array.

I have no idea why "susceptible to something like ROP" is especially relevant here. ROP is not the same as "writing over the return address" ROP is a technique you use to get around non-executable data sections and happens after you abuse some memory safety error to write over the return address (or otherwise control a jump). It means "constructing an exploit via repeated jumps to already existing code rather than jumping into code written by the attacker".

But just for the record, Java does have security monitoring of the call stack that can ensure that you cannot return to a function that isn't on the call stack so even if you could change the return target the runtime can still detect this.
I'm excited for this change, but only if they make more chargers available. I had a quick road trip from NC to VA and at the supercharger station, there was a line of cars waiting to charge - I can't imagine what that line would look like if it's open to everyone else.
If they'd have done that, we'd have missed out on 10+ years of improvements. Now seems like a fine time to standardize, especially since adaptors are feasible.

Nitpick: THW has the capabilities (hydraulic spreaders and cutters) and trains for vehicle extrication, but it's true that the fire department usually handles these situations because they are far quicker to arrive. Since vehicle extrication is usually rather time-critical due to the injuries that are to be expected in such accidents, and the fire department has more experience with it, THW rarely does it. Some local chapters do on-call Autobahn shifts (Technische Hilfe auf Verkehrswegen), maybe there?

Making one stall CCS wouldn't be that hard, but without details we have no idea what this will look like or the scope of what Tesla intends to do. This could easily be EU only.

I love my model 3 sr+, but am under no illusions about the company failings. Elon shoots his mouth off on twitter all the time and it wouldn't surprise me at all this is the first any tesla staff have heard of this plan, which would mean no one has any idea what this looks like in practice.

> Why would the Chinese government be interested in comparing what % of Linux users use the "reverb" function vs. Windows users?

Who knows? Personally I don't even really think it's about analysing the data, it's really just about having the data. Because "big data".

But from my perspective the philosophy isn't really about understanding why the data harvesters do what they do so much as protecting ourselves from the ridiculous number of possible misuses the data could have. It's the same principle that causes me to default to wearing a condom.

Is it a bubble? Or is it devaluation of the dollar?
Question: I live in Europe, I thinkI might end up buying to EVs in the next years. If, say, I buy a Tesla and a Kia, or a Tesla and a Seat, or a Kia and a Volkswagen, will I be able to charge all of them at home with a single charger? Is this "CCS"?
It's always been the case for me that it'll update everything I have installed, and won't let me proceed with installing a package until that finishes. No idea why, but it's obnoxious enough to make me never want to use it again.
How does this compare to https://github.com/GoogleCloudPlatform/terraformer -- looks like it is more continuously updating and user friendly?
AFAIK, China has invested considerably in controlling African port infrastructure and operations, not trade policy in the abstract. While owning a port often implies direct control over what goes through it, the converse is not true: a government can still control its own port infrastructure while being completely laissez-faire about what goes through it.
This actually seems to be mostly done already. EU mandated CCS and China GB 20234. So if Tesla has to support these anyway, it doesn't really make sense to maintain a Tesla-only charging network in these markets.

As I doubt the US will adopt GB 20234, my bet would be on CCS.
I believe the issue always was they'd have to use Tesla's billing infrastructure as there are no screens etc on the superchargers. I hear you though.

On second hand books, the Fabled Land gamebooks are almost a solo RPG/analogic RPG video game which can be played with no power :).

Also, a lot of the older books on technical terms are far better because the skills on similar education levels were far higher back in the day. For example, today's Electrical Engineering books from the first year in College were on par on senior HS years.
Let's just say, genomicists really do play fast and loose with these sorts of things. For exmaple, with the human/ape comparison, they only compared highly conserved regions and totally ignored regions that didn't match up. So that's just totally misleading because it's heavily biased.

This work is just attempting to use probabilistic reconstruction to determine the tree topology of genetic history, the pull quotes are sort of to make it sound more accessible to the public. The underlying reality is that this is an ongoing area of research with a lot of contention and most of the ideas are actually undersupported by the evidence, but scientists gotta publish.

It is funny how we created a mess with sexual liberty in the past century, and now we're trying to fix without giving up the debauchery. Sexual Morality reduces the problem of fatherless homes, rape, incest, sexual harassment, etc. Yet, people want to solve these problems with less sexual morality, not more. I hear people talk about consent. Yes, consent is important, no question about it! But hey, Sexual Morality is a better and bigger shield if consent is not combined with Sexual Morality, you have an empty effort that solves only a small piece of these problems.

The Chademo and Us CCS plugs are terrible. Objectively bad (expensive, heavy, etc).

The European CCS plug isn’t quite as good as Tesla’s but is probably good enough.

The Us should adopt either Tesla’s plug or the European plug.
That was a trojan horse offer. Tesla required anyone accepting the deal to give up their right to ever sue tesla over any patent infringement of any kind. Any automaker's legal department that allowed their boss to sign that would have needed to be immediately fired.

That's right. That's why when this experiment is actually done, the mirror is typically rigidly mounted to an optical bench, which is sitting on the surface of a planet. If the mirror were freely floating in zero G, the outcome would be different. It is a worthwhile exercise to calculate how small the mass of the mirror would have to be before you would actually notice a difference in the results.
