Please explain to me how you view how reality works then. I'm not related to SF in any way btw.

The total legal occupancy of SF is smaller than the number of people who want to live there. The city delays the issuance of permits for expanding occupancy.
True, this was a very nice suprise on my last tax filing. I had even almost forgotten myself about those donations!
You don't need to replace engines on new cars though, and that's the main discussion to have here - what do people care about when buying a brand new car? For a lot of buyers there's no maintenance cost for the first 3 years, so EVs have zero advantage for new buyers. I had a brand new Qashqai for 3 years, negotiated a 3-year service pack for it to be included in the price, and over those 3 years it needed nothing - no new tyres, brakes, bulbs, servicing was "free" so the car was as cheap to keep as an EV would be, except that it was a lot cheaper to purchase. And sure, over a longer period of time it is going to start costing money in maintenance - but I(as a new buyer) couldn't care less - it's simply not my problem.

Or as another example - we bought a new VW Polo for my wife some time ago, and there was absolutely no way to make a case for an EV instead - the price difference was so big that it will have paid for the fuel for a petrol Polo many times over, getting an EV made zero sense.
How Data-Driven Decision Making Is Driving Businesses Towards Success
A Decade in Review in Tech
> It will tell you how to start a conversation. Help you get dressed on a first date. Help you hold a conversation. Teach you étiquettes. Tell you what to do when you don't get an answer. These are all real relationship building tips that dating apps don't bother with.

I don’t think that’s what most people need help with, especially most females. The only people left would be supremely introverted males with a high dose of self-awareness (those few rare people openly admitting they need such help). Based upon my personal relationships who have used dating apps to meet people the audience is mostly people who have trouble finding people for dates or people completely lacking self-awareness. As a result that’s the audience most dating apps target and try to connect, which is why the real world results are sometimes underwhelming for many users.

Honestly, if the apps connected people with as strong compatibility as they claim users would not need multiple disappointing dates. The problem, in many cases, isn’t the app though (at least when the app does pick desired criteria). Some people seriously look into a figurative mirror and see something extremely different than what much of the world sees which likely explains why they might need a dating app in the first place.
> German automakers not only stopped their R&D to develop the next generation of cars.

Volkswagen is currently running a multi-billion euro initiative for the next generation of cars.
Even back in the 1980s, author Lance Leventhal who wrote some great programming books on assembly always warned that productivity wise you write the same number of lines of code whether its 6502 or C.

As that 6502 example in the article shows, you don't great great productivity with assembly. And even macros don't improve on it that much.
> As of 2016, around 40% of the electricity in the country is generated from coal.

As of 2019 this is 28%.

> Germany has been opening new coal power plants until recently

While closing many older ones.

> following a 2007 plan to build 26 new coal plants

Which it didn't.
It is a good reminder, which needs to happen more often.
Only a gut feeling (no real proof), but it seems like the younger generation does not care because they're so exposed from an early age to all kinds of social media, influencers, streamers, etc.
The older generation does not seem to care because they're a bit technologically impaired and it's hard enough to try to keep up.
There are exceptions though, and depending on the bubble you live in, the number of exceptions will differ a lot.
Date computations like this are not at all tricky.
I use TextExpander. I wanted to do some custom stuff and discovered this recently [federico-terzi/espanso: Cross-platform Text Expander written in Rust](https://github.com/federico-terzi/espanso)

I tried espanso a bit and it seemed to work pretty well and is customizable.
In my opinion, this does not mention the main point. Individuals (plus families, small communities, small businesses) loosing their power (privacy in this case) means corporations and governments get (even) more power. I’ll live it as an exercise to the reader to see why the latter trend might not be so good in the long run.
Yes there’s a supercharger there but as my colleague explained it you can forget about it when you’re at an event where many other Tesla drivers go, as you’ll have to queue a long time to use it. As I said EVs will be awesome when the infrastructure is finally there, right now it isn’t though so for most people gasoline cars are still more convenient.
Rarely do I have income not on a W2 or 1099. Should automated.
Increase in the money supply and velocity of money. The money supply has increased dramatically and is why the bull market has been so long. However velocity is very low which has so far limited inflation. UBI would thus likely cause significant inflation.

The bay area is rich and the rents follow suit. They are still limited to the overall supply of money in the area. Obviously increasing supply of real estate would help the issue of course.
True that, I’ll add those!
It is not inflammatory or false. VAT taxes are regressive consumption-based taxes, and poorer people disproportionately bear the costs compared to the wealthy. It's very well established among economists https://www.quora.com/Why-is-value-added-tax-regressive

> I doubt you've lived through any sort of poverty or have felt like the walls were closing in on your life, but people live that everyday. For those that have been through it, it hardly feels like a "weird 10x play"

The poor and working class of this country clearly have a candidate they stand by, and it's Bernie Sanders, who is about to set a record for the largest number of small dollar contributions in US history. You won't find them at $5600 a plate dinners at Sam Altman's mansion in California. To their great credit, the working poor in this country seem much more interested in an agenda that proposes real change to systemic inequality and poverty, rather than just pouring some regressively funded UBI candy coating over the existing broken system and expecting it to not get much, much worse.
There are many ways to do this. A valid reason for wanting to do this is that doing database imports takes time and sometimes you just want to get to the joined data set without having to wait for that.

A few years ago, I was trying to turn open streetmaps dumps into json documents. OSM ships as a huge bzipped XML dump of what is essentially 3 tables that need to be joined to do anything productive. One of those tables containes a few billion nodes. Importing that into postgreql takes many hours and takes up diskspace too. Bzipped, this stuff was only around 35GB. But it unpacks to >1TB. So, I wrote a few simple tools that processed the XML using regular expressions into gzipped files, sorted those on id and then joined files on id by simply scanning through multiple of them. Probably far from optimal but it got me results quick enough. Without taking ages or consuming lots of disk.
Yeah, let’s see how it evolves!
IMO mutexes, semaphores, spinlocks should be used only in special cases (e.g. games or other high perf logic where you need to maximize performance by a fixed percentage) because they are anti-patterns for scalability. They only help to scale up to a point after which all the threads either spend all their time waiting for each other to release the locks or they can never acquire the locks because the demand for that shared memory is too high. There are exceptions for example if you have unlimited reader threads/processes compared to a fixed number of writer threads/processes but even in those cases, I feel that shared memory locks add invisible bottlenecks to scalability as the code evolves over time.

For most of my use cases, I prefer to keep processes/threads parallel and communicate via IPC chanels/sockets. This makes it easier to write code that can scale without limit.

For most use cases, I don't see much point of writing scalable code that you know only scales up to a certain point and then needs to be rewritten.

Avoid using shared memory if you have an embarassingly parallel problem.

Quick way to do it would be to calculate some high index in a fibbonacci sequence at compile time using templates.
Yeah! We used to play Slicks ’n Slides a lot for example back in the days..
I see this argument ("similar capabilities for 20.000 € or less") a lot, and I'm not buying it. I supposed it depends on what "capabilities" you're talking about (number of passengers?), but a Tesla is going to be faster, quicker, safer, cheaper to fuel and cheaper to maintain than any 20.000 € car I can think of.
Informed Voters (1993)
I'm in LOVE with my side project, OneFiftyOne (onefiftyone.run). It gives me intense satisfaction, and I get to take part in politics on the ground floor and feel like I'm really making a difference and having an influence.

That being said, I'm currently at exactly $350 MRR. I'm a young (25) newlywed with no parental financial support and my wife is a student.

I'm trying to get into an accelerator (just applied to my local TechStars) to help give me a runway that I don't have to have a full-time job. That's plan A. Regardless of plan A's success, though, I'm working my ass off to get it more profitable to be able to support my wife and I.
those shitty jobs are most vulnerable to outsourcing, automation, made obsolete, etc

Most of those jobs will be the hardest to automate because Moravec’s Paradox. Automation will wipe out lawyers and accountants long before it reaches sewer maintenance and refuse collection.
As mentioned elsewhere in the thread, we're working on a major rewrite of the Redux core docs. If you've got any specific suggestions on how we can improve them, please let me know.

When you say "no quick and easy way to get started", are you referring to code or docs?

In terms of explanations, RTK is currently documented as a separate layer on top of Redux, because that's really what it is. So yes, we do assume that folks have learned what Redux is and how to use it already, and RTK is then a faster and better way to write Redux logic instead of doing everything "by hand".

As part of the core docs rewrite, we do intend to completely redo the tutorial sequence, and we'll be introducing RTK somewhere in the tutorials and encouraging its use.
How I Started My Company While Working Full-Time
US income and disposable income figures for the middle class are among the highest in the world. Only a few wealthy countries like Switzerland and Norway compare. In terms of household disposable income, the US is the highest in the world. The full-time median US job pays about $50,000 now.

The US household disposable income figure is drastically higher than in most of developed Europe. 50% higher than Sweden, the Netherlands or Finland:

https://www.statista.com/statistics/725764/oecd-household-di...

This is has been true for a long time:

https://skift.com/2013/05/15/u-s-has-the-highest-disposable-...

The median household disposable income figure typically places the US in the top few nations:

https://mises.org/wire/when-it-comes-household-income-sweden...

The median household wealth figures are higher in the US than in Germany or Sweden (but lower than France or Britain).

The US also has an extremely progressive income tax setup, with the middle class having among the lowest income tax burden of any developed nation.

At $50,000 in a typical city like Atlanta or Pittsburgh, the typical person will pay 20% in total income taxes. In Texas (no state income tax) you can climb up to around $70,000 and still stay under a 20% rate. In most of the US you can make $200,000 and still be close to a 30% rate. The US middle and middle-upper class is entirely oblivious to how hyper low their taxes are (as a trade-off they are not getting guaranteed universal healthcare either of course, their employer must cover it or they have to).

If the US ever fixed its healthcare disaster and brought costs under proper control (shaving a trillion dollars in annual costs), in financial respects at least it'd be nearly a paradise.
the timing is hard to get right

Yes the timing is tricky and decay is a bitch.

My thesis is that the market will begin to drop in January. Perhaps as soon as January 2. The puts are to protect my portfolio from that scenario. If the market doesn't drop I will quickly blow out of my put options.

The time decay over a few days or even weeks on a 90 day option isn't that significant. Of more concern is that the price of a put will decline if the market continues to move up away from the strike price. It's a double whammy because, as a market moves up, the inherent cost of options (the implied volatility) usually goes down as well.

Or if you're a true believer, then you'd roll over your options, and keep throwing money down.

Yes it's foolish to keep rolling put options in a rising market. You must use them tactically for when you expect an inflection point might soon be at hand.

You can also use put options for more practical reasons. E.g. in my case I need to periodically sell stocks because I have tuition to pay for my daughter currently in college. Two scenarios:

1) stay in the market, buy puts, lose some of the upside because of cost of puts.

2) sell stock now against future tuition needs, lose all of the upside.
It looks like there's a few iPod Video models on eBay for $16.
It's just a multi-year initiative. Takes a bit time to develop the cars, have the factories for them and bring the cars to market.

If you follow Volkswagen news, you can see that they are steady making progress and and have a very large initiative.
To be fair, this is three-and-a-bit years of experience in this area, so it's not like I've learned this in my eight weeks of lectures...
I see. So I guess it wouldn't make much sense, without adding more new rules.
By simply spending too much of their income to buy said overpriced assets
My program’s much more mundane than using templates as a Turing complete language at compile time. Just a slightly tricky static node pool for a persistent segment tree. Allocating a larger pool causes more RAM usage at compile time, at a 20+x ratio. Probably not gonna share code since I didn’t bother to distill it down to the cause.
Right-to-left styling: a guide on how to style for RTL in CSS
That would seem to work.

Another approach could be that yes you must fill the first two rows of your side initially, but players would take turns in doing that piece by piece. You would see how your opponent places their army piece by piece on their side and you would adjust your placements accordingly.
If you're using a regressive VAT tax to pay for UBI you are not redistributing wealth, you are disproportionately taxing the poor to distribute to themselves (https://www.quora.com/Why-is-value-added-tax-regressive) much of which will be lost as the prices of goods increases to match equilibrium. Amazon won't "pay the tax" it will pass the tax along in the form of higher consumer prices.

If the primary concern is tax evasion, there are many ways to improve this while still maintaining progressive taxation.

And I'm sorry, but even if this would work, I'm still not going to be sold on the idea that the world should be lorded over by a few trillionaires from California.
Ask HN: An alternative to TI EZ430-Chronos watch/dev board?

Your analogy is ironic because there is almost no cafes in Germany with free wifi. The telecommunications infrastructure in general is terrible. Even directly in the city center I barely have mobile internet reception and I have doubt that with EV charging stations it will be different, especially with all the corruption coming from the car manufacturing corporations.
If you’re living in the countryside it’s usually not an issue, most people in major cities park their cars on the street though, so for EVs to become viable you would need a much better infrastructure. This will happen but I estimate it will take at least 5 more years.
VW is owned by Porsche not the other way around.

This is incorrect, and the story behind VW buying Porsche after Porsche attempted to buy VW is one of the greatest stories in corporate finance. Additonally the two sides of the Porsche/Piëch (Ferdinand Piëch - VW Chariman - was Ferdinand Porsche's grandson) family were rivals, and Ferdinand Piëch had an affair with his sister-in-law Marlene Porsche.

https://ftalphaville.ft.com/2018/10/31/1540962002000/The-day...

Here's the second half of that story, where VW got there revenge on Porsche for the attempted take overs.

How is the rate of demand for dollars growing?

Hint, global assets are all available for purchase on dollars. As more and more products get built in China and other countries and they are all willing to accept dollars for them, the rate of demand for dollars increases.

As for visa on arrival, most countries on it are similar GDP-wise. Which means their citizens have a low cost to convert to USD and their capital accounts are open so citizens can freely chnage into USD.

So their domestic currencies are almost as good as USD (or even Euros to some extent)
If by kind of fits, you mean the entire problem? Yeah.

Of course, the epoch is so arbitrary that a decade means nothing anyway, whether or not it's a year off.

If people like numbers flipping back to zero, we should just tell time in binary.

The Japan government has a huge debt. But it is mostly owned by Japanese people and firms. If you look at the whole Japan country, state, people and companies together Japan is not in debt, but is a net creditor. So very different from the US as a whole.

It’s because all of the skills that are required to become an executive are just as, if not more, important to have when you actually are one.

The mirror has to move out of the way and the aperture must close to the chosen value.
Well that would be fantastic, I think the model 3 is a nice car but for what it is I find it quite overpriced right now (probably a good strategy for Tesla though as anyway they need to ramp up their production first so they sell at a price that creates just enough demand for their capacity). I think at 25.000 € I would be happy to buy one. Right now I could still buy a Mercedes C class hybrid for the price of the Tesla here. As I don’t need a car urgently I’ll wait a couple of years in any case, it seems there will be a lot of movement in the EV space in the coming years.
and Andrew Ng's ML course?
> Bubbles happen when everyone in the market is stupid.

No. Bubbles happen when interest rates are low or via other mechanisms ( QE, etc ) excess capital is created.

> Stupidly believe nothing could go wrong.

No. This is just standard nonsense we teach entry level financial analysts who know nothing or something the business news parrots. The "stupid" masses don't create bubbles. The highly "intelligent" financial masters do - FED/banks with the help of politicians and media.

> The only risk I see right now is China. Simply because the market is so opaque we have no idea what is really going on.

Another one of these. Once again, somebody has to link china with something that really has nothing to do with china. Also, the chinese markets aren't any more "opaque" than any other markets. Really, you have no idea what's going on there? I thought china was collapsing because of all the "ghost cities"?

The anti-china crowd is so hilarious. On the one hand, china is a risk because we know exactly what's happening there. On the the other hand, china is a risk because they are "opaque" and we have no idea what's happening there. Sometimes it's hard to tell whether these comments are from propagandists or those mindlessly parroting the propaganda.

But in the meantime, people who know nothing will argue about silly nonsense PE, EPS, Beta, etc. There is a bubble because the big boys want there to be a bubble. APPL rose 84% because the big boys wanted it to. The bubble will pop and there will be a recession when the big boys decide.

"I nearly stopped reading after this. In hindsight I should have done exactly just that.". Amen to that. Should be the HN motto.
there is many uses where charging will be at least problematic. e.g camping away, or doing a road trip, or doing farm work. It's not enough for cafe's to provide chargers, because it's not as if people park right outside businesses, especially in old european towns.

i live in an island that is powered by an Oil power plant. it would be bad for the environment to use an electric car, power outages do happen, and the city is old and badly designed so that for the vast majority of people it's not possible to charge at home, they d have to add charging stations on every street.

i guess for the tesla's market - which is above average buyers - it is possible to charge easily. or it also happens to be their second car
They're quite awful cars thpugh. I had a rental C3 Aircross in Portugal, it wouldn't climb a moderately steep hill without pressing the pedal to the metal.

It is exactly the way I'm thinking. More importantly, the order of the digits doesn't matter, so if 12 is divisible, so is 21, 102, etc.

> German carmakers make as many cars per day as Tesla makes in a year

This may have been true three years ago, but Tesla made over 350000 cars last year. By your math the German carmakers are making 128 million cars per year. They are not.

My issue with brakes is that they rust because I don't apparently use them enough.
