This is an ongoing JavaScript learning exercise. Tons of fun. I used THREE.js for the 3-d effects. It includes a (really inefficient!) solver.

There are radio buttons that select from among eight sub-problems that progress through levels of difficulty, culminating in the full cube.

The 3-d graphics aspects of the implementation were interesting - I wrote an alternative "change camera position" function that suits the symmetry of the Rubik's cube better than the default one in THREE.js. It was very interesting implementing mouse-based face selection and movement in the presence of a perspective projection.

I added a "Record/Rewind" feature, which is in fact a big hint on the key idea for solving the cube: commutators. (If two top pieces are similarly wrong, fix one of them and record the fix. Then, move the other one to where the first one was, and "rewind" your fix!)

Future ideas:
1 - add a scroll bar so that users can explore solutions one move at a time, and go backward and forward.

2 - add links to a text-based web page with hints and suggestions.

3 - add more intermediate sub-problems, with "scramble" options. I.e., have a sub-problem with only the top face and one corner cubie out of place. Have the "scramble" put that one cubie somewhere else, but leave the rest of the top level in place.

4 - HN: any other fun thoughts, suggestions, or ideas?
I’ve listened in on a few community board meetings on road safety in New York City in order to better understand the situation, and was really put off by how the bicycle advocates were simultaneously demanding more protection from the police while openly mocking the suggestion that they need to stop running red lights. The hypocrisy of disrespecting the law while requesting more severe enforcement of the law against their opponents felt really gross and caused me to check out on the issue of bike safety completely.
"The State of Linux Debuggers". This is ... not that. Perhaps "One inexperienced user on an uncustomized system briefly trying several default-configuration front-ends (some of which are apparently malconfigured or missing dependencies) to GDB, without resorting to any documentation whatsoever, and gauging them solely on layout and visual appeal."

Pro-tip. When working with a new debugging environment "I haven't found a way to display the backtrace, list local variables or view memory" would be where most would look at documentation or seek advice, not move on to the next tool. That the author didn't is more of a comment on the reviewer than the product.
Even if Tesla does everything great there will be irrational exuberance and selloff: to compensate for the high growth of the company, the volatility has to be much higher for than a traditional car company.
''Essentially, the AIM method involves informing suspects of these facts. Specifically, interviewers make it clear to interviewers that if they provide longer, more detailed statements about the event of interest, then the investigator will be better able to detect if they are telling the truth or lying. For truth-tellers, this is good news. For liars, this is less good news.
Indeed, research shows that when suspects are provided with these instructions, they behave differently depending on whether they are telling the truth or not. Truth-tellers typically seek to demonstrate their innocence and commonly provide more detailed information in response to such instructions.
In contrast, liars wish to conceal their guilt. This means they are more likely to strategically withhold information in response to the AIM instructions. Their (totally correct) assumption here is that providing more information will make it easier for the investigator to detect their lie, so instead, they provide less information.'

......

This asymmetry in responses from liars and truth-tellers - from which the AIM technique derives its name - suggests two conclusions. When using the AIM instructions, if the investigator is presented with a potential suspect who is providing lots of detailed information, they are likely to be telling the truth. In contrast, if the potential suspect is lying then the investigator would typically be presented with shorter statements.''
Other car makers also make a lot more than just cars. More so than Tesla, probably.

Most of them include banks, for example. They usually started out financing their customers' car purchases but in many instances have expanded beyond that.

Peugeot makes pretty nice bicycles :)
This is going to backfire spectacularly. There is no filter which can isolate the good from the bad. If you let the flood gates open the scum will come in too.

No, it's just that Europe and China have the priority for the larger manufacturers because they have stricter fleet emissions standards.

Most sidewalks are way too damn narrow for passing a pedestrian IMHO. I stick to bike trails and side streets, sidewalks only exist in my route planning for emergency maneuvers.

Also I live in New Orleans where having a few feet of very broken, ragged sidewalk due to a tree's roots bursting up through them as the pavement slowly sinks is a very common sight. Trust me you do not wanna bicycle on that shit.

''We found that when the AIM technique was used, it was easier for the interviewer to spot liars. In fact, lie-detection accuracy rates increased from 48% (no AIM) to 81% – with truth-tellers providing more information.''
My experience as a long-time Googler has been that people do 20% projects for two main reasons:

1) They want to change their role and view the 20% project as a means to an end. As an example, I worked with two 20%'ers that wanted to transfer from non-SWE to SWE roles. One of them has already succeeded, and another is hoping to be able to do so as soon as head count permits.

2) As a labor of love. As an example, we have an epitaphs page containing information about/farewells from people that have departed Google. It's not an officially supported project but is still quite popular. These kinds of projects don't necessarily lead to promotions (although the criteria for promotion have recently changed), but on balance they make people's lives better.

Tesla is making big investments in building factories, both for cars and batteries. Those numbers should increase significantly over next 5 years.

They have more vertical integration, less reliance on suppliers.

They own their 'dealership', charging network and are also getting into auto insurance.

Also, residential solar and energy storage. Oh yeah and they are getting into mining as well to ensure they can keep up the battery production.

How many of those 92 million cars are EV? Tesla isn't really in competition with ICE car production - the next ten years is all about EV production and legacy car makers are off the back.
The large print giveth, and the small print taketh away.

They have raised the price of a shell corporation from $0 to just the barest possibility of $10,000, but actually never. Also, if you make a "hedge fund" ($0) the law doesn't apply to you anyway. NP.

Just like before when they passed all kinds of money-laundering laws, but completely exempted real estate. So, you want to launder money? Real estate. NP.

Hedge-fund controlled shell corporation buying and selling real estate? NP.
As one example, the Michigan case King v Whitmer:

https://www.courtlistener.com/recap/gov.uscourts.mied.350905...

https://www.courtlistener.com/recap/gov.uscourts.mied.350905...

In the plaintiff's prayer for relief, one of the reliefs requested was that illegal ballots be thrown out (illegal ballots, meaning ballots counted in a manner that did not comply Michigan Election Code)

The judge however has determined that the requested redresses would not be available, because it would disenfranchise voters. Because of this, she would not be able to provide redress "Even assuming that Plaintiffs establish injury-in-fact and causation under this theory".

This was one of the main reasons for the opinion. There were other reasons (e.g. laches). The issue of redress / equal protection, however, was repeated several times in the judgement.

For the most part, the judgement does not address the actual claims being made. Below is one of the few quotes where she does address the actual claims:

> For example, the closest
> Plaintiffs get to alleging that physical ballots were altered in such a way is the
> following statement in an election challenger’s sworn affidavit: “I believe some of
> these workers were changing votes that had been cast for Donald Trump and other
> Republican candidates.”9

The above statement, as far as I can tell, is just factually not true. The plaintiffs do allege that physical ballots were altered in a fraudulent way. See the section: "Election Officials Added Votes and Removed Votes from “OverVotes”.
It's just astonishing how casual an attitude we take to cars when they've done so much to bring carnage to our road and damage to our environment and when they squander so much public land in our cities.
And yet not a single one of them was able to make electric cars attractive enough to buy until Tesla showed them the way.
Coinbase's insurance is limited to say the least. Namely, it only covers losses from hot storage (<2% of holdings) and it doesn't cover losses due to compromises of an individual account.

Coinbase maintains 98% or more of customer digital currency in cold storage, with the remainder in secure hot servers as necessary to serve the liquidity needs of our customers. All digital currency that Coinbase holds in its online hot storage is insured. If Coinbase were to suffer a breach of its online hot storage, the insurance policy would pay out to cover any customer funds lost as a result.

Interesting. Seems sorta like the English shorthand "if a less-than b, do this" (as opposed to "if a IS less than b, do this"). "Equal" is almost a different story since it works as a verb as well as an adjective.
No, he’s saying judging Tesla’s market cap based on car manufacturers is like measuring Apple relative to other watch manufacturers. Ford doesn’t do direct to consumer sales, own a charging network or even gas’s station etc. Yep, they happen to build cars but if that’s the kind of analysis you’re doing the market will eat you alive.

I don’t think it justifies their current market cap, but plenty of companies looked over priced 10 years ago yet ended up being great investments. Hell, I remember thinking Bitcoin was pricy at 30$, watching it crash etc.
Electric vehicles are not cheap.

Toyota should just market their hot electric sports car under the Lexus brand.

Those that can afford a Lexus can easily afford a luxury electric car. Or shell out $80,000+ for a fancy whiz bang electric car.

This gave me chills.

If I understand this correctly, they'll be able to write their own checks because they will essentially...

1) Own self-driving and thus, most personal transportation

3) Own / replace a large segment of public utility / power companies

4) Own / replace a large segment of insurance

5) Own / replace transportation power network

Right now, it's silly to think of Tesla as some kind of mega-monopoly across industries. So we invest in them betting on them becoming that. Is that what we want?

My counter-argument is that one of the bigger markets for automobiles, the U.S., is designed around personal choice, personal autonomy, etc. Many people just want a working car to give them freedom, and will buy whatever popular, trusted brand is available. The rest want one of the smaller brands, something that seems different from the mainstream (even if it's really barely skin deep). That has kept quite a few big players in the automotive marketplace, and despite consolidation over time, there's still variety, which buyers want. This argument really only addresses them as a car maker, though... and not at all for their spread across industry lines.
It may sound silly but I try to project forward to the end of the day and simply have my future self judge what my current self is doing. Would I be happy if I wasted time or would I be happy if I made progress on a project? That usually centers me to get the "right" things done.

I don't find tags useful for many of the same reasons that I invented this system.

What's the tag for the payroll schedule? Is it 'Payroll'? 'Finance'? Something else?

Who manages the tags? Can anyone add one?

Tags need managing just as much as -- if not more than -- a well-organised folder structure. Tags aren't just some free magical way to organise stuff ... otherwise I dare say they'd be more popular.

>Tesla is they are still very much trying to figure out the manufacturing and logistics pieces of building cars (rolling out new lines, scaling them, etc). The existing automakers know how to do all that

I have to disagree to some extent with that. I think by now Tesla has figured out the logistics of assembling cars at least as well as other manufacturers, but they still nees to build more lines however.

However Tesla is not stopping there and is continuously improving its logistics past the industry standard, it's not catching up anymore, it's pulling out. For example a lot of effort right now is invested into streamlining battery making and integration, this is something no other OEM is really doing right now. Tesla is willing to take on battery production and even potentially mining, allowing them to fine-tune and optimize the process end to end as much as possible, while traditional OEM rely on suppliers for everything and any improvement needs to be negotiated and takes forever.

Tesla last battery day had an extremely interesting presentation about battery making and logistics that illustrates just how deep the stack they are willing to go for the sake of optimization.

Better Records – 'No two copies of a record sound the same'
Who isn’t allowed to talk about that, and how?
Not really. The previous comment was suggesting that sexism in the marketplace (the perception of a female CEO) is somehow being accounted for in a VCs decision. I’m arguing that VCs need to look at things differently - not just playing to the ‘strengths’ of the market just for a quick return, but actively creating opportunities for a perception change.
No one is arguing a compromise of the update server doesn't allow compromising all customers. They're arguing that the benefits out auto-updating software (especially consumer software) outweigh the risk of a compromised update server, which is generally true.
I am not so sure about the loosen regulations thing. The US had periods of time with virtually no regulations. Rivers caught on fire, people were maimed and died of industrial accidents at much higher rates, water was unsafe to drink, ect. The countries now without much regulation are usually poor, dirty and dangerous. I want to live in a safe, clean, healthy environment.

I agree with you on the tariffs. China should not be able to outcompete us because they pollute and use slave labor. Force them to compete on fair terms.
But with a bank you don't look at market cap, so still a bad comparison.
I have invested (read: gambled!) on and off in Tesla. The Elon factor concerns me as a long term investment. Do people think the company will continue to grow at the rate they are if something happens to him? Worries me to put so much faith in one guy, despite his insane accomplishments.
For a second there I was wondering who this famously gay "MBS" was supposed to be.
That’s not really how it is though, these are very different companies with very different products. For example, Ford makes its money on trucks. An F-150 has very healthy profit margins. It’s believed that Ford’s truck business is in fact worth more than Ford as a whole [1]. The Fiesta hasn’t been sold in the US since 2019.

That's not a fair comparison...

Perhaps it could have been phrased better, but I think all he's trying to say is something to the tune of:

"by current estimates, scientists think the pandemic will be largely dealt with by next fall due to the efficacy + distribution of the vaccine, so the thing stopping us all from being together outside will probably go away, so we can finally go to the movies again"

I don't think it's an entirely unreasonable claim, but at the same time... I think he's just venting since he's (understandably) frustrated.
Very enjoyable. And makes you appreciate the challenge of EV infrastructure in the developing world.
Global by Nature: Public Companies to Watch
Triggered. :)
I wish my company did this, it would give me time to flesh out all those ideas that I have as I do my regular job, but "we don't have time for that" that I refuse to take home with me :) 8-9 hours of coding a day is enough for me. I actually worked on an automation system (mostly on my own time) that literally reduced the "manual human intervention time" to an 8:1 ratio. I'll admit it was rough first and I estimated it would take me time to train a typical technician a day or two to wrap their head around it but it could be done (I actually trained one tech on it during an all-nighter demo to him, and he loved it). Anyway fast forward a bit, I presented it to my manager and his manager and he said "we don't time to train techs on that, we have to get work done" and I had already trained 1 tech on it, and we did it on our on time! I was so dejected after that that I left the company about a month later and was much happier.

> And low interest rates (part of government stimulus).

What do low interest rates have to do with this?

All stocks are up somewhat due to low interest rates -- why should Tesla's stock be an outlier unless something else explains its rise over the past year?

I'd like to see some numbers on this, but I don't think most Tesla buyers finance their cars. I bet most pay cash. So low interest rates don't really explain their sales numbers either.

So, how do you think low interest rates help Tesla?
> The openness of the APIs offers those interested the ability to create their own features on top of a base

The tough thing is that those companies often close or undocument those public APIs because serving you ads is always more profitable than not. Open APIs also encourage aggregating and refinement behavior, which if done outside the parent company would be a detriment to their profits as well.

You're, in essence, asking one of two things:

- Figure out how to monetize APIs

- Change the incentives of the web to be less corporate

The latter would require that the web be significantly cheaper to run. The former would create quite an equal access and innovation problem.
