I think a lot of people need to start from the basics because they don't have a good foundation in math. The core problem is schools will push you along if you can somehow produce the correct answer for 70% of the problems on a test. Combine this with intense pressure not to fail and you will very likely end up in higher level math courses with many gaping holes in your foundational knowledge. You thus end up relying on tricks and memorization rather than useful understanding. Here is a TED talk where Sal Khan of Khan Academy talks about this: https://www.youtube.com/watch?v=-MTRxRO5SRA

After struggling to understand advanced math in a lot different contexts I decided to go through the entire K-12 set of exercises on Khan Academy. I blazed through the truly elementary stuff like counting and addition in a few hours, but I was suprised at how quickly my progress started slowing down. I found I could not solve problems involving negative numbers with 100% accuracy. Like (5 + (-6) - 4). I would get them right probably 90% of the time but the thing is Khan Academy doesn't grant you the mastery tag unless you get them right 100% of the time. I found most of my problems were due to sloppy mental models. Like, I didn't understand how division works -- if someone were to ask me what (3/4) / (5/6) even means conceptually I would not have been able to provide a coherent, accurate explanation. "Uh... it's like taking 5/6 of 3/4... wait no that's multiplication... you need to flip the second fraction over... for some reason..." It was around the 8th grade level that I found myself having to actually work hard. (What does Pi even mean?) And I've been through advanced Calculus courses at the university level.
Thanks for those suggestions
No, just start with a new phone, and never get a Google account. You can then remove most Google stuff, install F-Droid, and download open source replacements.
I'd be interested to learn more about what you're proposing (if this is possible).

I've thought for some time that this is one area where (as you say) there's a clear social need, and that the solution is for a non-profit lending organisation to offer the loans. As in, the lending company would, overall, aim to break even once the cost of operation, loan defaults, and profit from loans are taken into account.

It probably goes without saying that the loans would have a higher interest rate than those seen with longer-term standard loans, but I'd imagine they'd be orders of magnitude lower than some of the awful, predatory rates --many over 1000% APR-- that we typically see with UK 'payday' loans.
I would rarely use a product I needed to pay for. On the other hand the products I pay for I usualu get more enjoyment and/or more productivity.

If I was using it and the price went to a dollar I would probably continue.
"Soon" is not the same as "already hit". Some likely gambled on beating the deadline and may cancel now.

Tesla, Inc. Q2 2018 Financial Results and Q&A Webcast
Because car companies are horridly shortsighted. All of the major US car makers right now are doubling down on building gas-guzzling pickup trucks and SUVs because they have a nice profit margin and because Americans love commuting alone downtown in traffic every day in their seats 7, 20 mpg abominations with trunks and beds that are never used.

Maybe it's what's necessary to survive in the moment and maybe the moment is the nature of the car industry, but all of these car producers seem to forget what happens when gas prices rise and the economy slows. Maybe then they'll actually innovate, but in terms of technology they're already playing catchup to Tesla. If Tesla can figure out how to produce these cars steadily traditional car makers are in trouble.

The last entry in the FAQ (https://news.ycombinator.com/newsfaq.html) says:

"Throwaway accounts are ok for sensitive information, but please don't create them routinely. On HN, users should have an identity that others can relate to."

There's room for interpretation here, but I think it's fair to say that the preferred default is the consistent use of a single permanent identifier. Do you prefer a different approach?
Picking on the code bit more while we are at it, random.choice that randstr uses is of course not backed by CSPRNG so its not ideal for salts. Although I would be shocked if attackers would be able to exploit that in any way.

Kinda interesting is how they decided on specifically 3 characters for salt, which seems really low. Its not like the characters cost anything, why not 30 characters instead?
I can't think of anything that's for purchase on this planet that is actually cheaper than one freaking dollar per year.

well the phase out will cost the least able to afford the car the most. I can still order a LR and get it sooner than the two people I work with who are awaiting the standard edition. Now I haven't asked them if they will continue to wait but even if I did order; I am not; its a random two to four months for me, which means I doubt any standard model would even ship before end of year
I assume that the established auto manufacturers are hamstrung by deep-rooted affiliations with big oil.

Who are the sponsors slathered all over their race cars? Petrol companies.
> Is that graph of their market share true? Do they really have a ~50% market share? It sounds really high. At that sort of percentage can they really grow at the rate they need?

Yes, when comparing to other compact luxury sedans such as the BMW 3-series and the M-B C-Class, yes, they are at 50% market share. The question becomes, are they just selling cars to people who would have bought a car in that class, or are they selling to people who normally would have been in a lower class. Anecdotally, they're growing the class, as there's a lot of interest in the Model 3 from people who otherwise would have bought a Camry, Accord, Malibu, or other mid-grade sedan.
Say they get 30c per user.
You get 1T traffic for $1, so 300G for 30c. That's roughly 40Gbytes per year or 100Mbytes per day. As long as people are on expensive mobile plans, there won't be more data.

Yes I do! I feel much more open/relaxed after speaking up in a meeting, it's like the pressure is off and can feel more normal. But it wears off quickly and then it's back to the usual. I don't know how to create those emotions regularly.
> but why not a standard looking body instead of some weird buggy space-age thing?

I think they're still counting on the signaling. It's said that the Prius was bought by so many in large part because it looked so goofy, in that it didn't look like anything else, so everybody knew it was a Prius, which by proxy meant that you were driving green.

Tesla shook that up, but styling still remains something withheld for the maximum dollars. There are very few stylish cars at cheaper price points because they know that despite whatever features are there, people shop with their eyes predominately.

If they happen to land on a design that's too fetching for the price point they're targeting, it seems likely that they'd uglify it somewhat and withhold the better design for a more expensive vehicle that they may or may not plan to make.
the ugliness is intentional, and i think this was even acknowledge by bmw execs to an extent. the margins on EV are comparitively very low, the (battery) supply chain is fragile. less profit + production headaches = don't make the product any more appealing than it needs to be
https://www.businessinsider.com/tesla-model-3-market-share-c...

Tesla has a history of drawing misleading market share graphs by comparing its cars against cars that reasonably would be considered to be in different market segments. You would have to be pretty charitable to call the model 3 a mid-sized sedan, for example.
Hey, wasn't aware of that. You mean like? :

>The Korean War ended up benefitting South Korea in the sense that they didn’t up like North Korea

This is an incorrect understanding of Korean history. US anti-communist policy played no small part in creating North Korea in the first place.

In the postwar period, US support for the right-wing dictator Syngman Rhee, who murdered tens of thousands of Korean citizens he suspected were his political opponents, empowered and drew popular support to Kim Il-Sung. Sung was further bolstered by the US giving favored status to Japan over Korea, forcing them, for example, to purchase goods and expertise from their brutal, former colonial rulers. With this state of affairs, Sung, a former anti-Japanese resistance fighter, was successful in persuading many that that the US-backed rule of Rhee was just an extension of the pre-War colonial rule, ultimately devolving into the never-ending civil war we have today.

This in no way benefitted the south, but instead has been a nearly 70 year long drag on their economy, as well as their development into a liberal democracy (which really didn’t happen until a popular revolt in the 80s because the continued US to provide financing and support to authoritarian rulers in the south).
Entire yeast genome squeezed into one lone chromosome
The price an advertiser pays to be a full page ad in the NYTimes and printed with the paper is on the order of $150,000, the price an advertiser pays to obscure your entire screen with an ad is as little as $1.00.

What you're missing is that advertising rates for television and print are several decimal orders higher than the rates for internet advertising. Why that is is more complicated than you might guess, but the economics of "printing" a newspaper by sending you the text is a couple of orders of magnitude cheaper than running a printing press. Between those two realities a lot of news web sites are being crushed.

Plausibly. For example BMW 3 + Audi A4 is only around 100,000 per year in the US combined.

The Tesla skeptics have gone out of their way to try to ignore what a dramatic accomplishment selling so many Model 3's so quickly represents (and doing so at such an elevated price point).

To top it off, the reviews keep coming in that several of the more ridiculous early manufacturing problems with the Model 3 have been fixed, such as panel alignment and seat comfort.
A new book came out recently about the history of Silicon Valley called "Valley of Genius: The Uncensored History of Silicon Valley". I've been working my way through the audiobook and it tells the story of General Magic in there. Would 100% recommend- it filled me with the same excitement as reading Steven Levy's original "Hackers".
Yeah, I definitely think that I lack confidence in social situations but too often it's just too much and I withdraw almost completely.
It's weird, reading that article reminds me about all of that talk in the 80s. It was a real, undebated (for the most part as far as my bubble went) thing, the question was, "what are we going to do about it?" Ideas were put forth, etc.

And then it's like we talked ourselves out of it. Then someone found an old copy of Time magazine at a yard sale, and said, "aha! See, they can't make up their minds!" No, "their minds" were kind of made up, don't let a crap article from a weekly news magazine sway you.

I haven't finished the article; I'll do that tonight, because I'm kind of curious in NYT's take on why we changed our minds.
Non-bank lenders have plenty of other motivations besides usury.

- Many immigrant populations thrive because more established members of the community invest in and loan to their peers (especially family members). They may not have twenty years of credit history and market research, but they have close-knit ties that go back generations and a person's reputation as leverage.

- A Planet Money episode after Hurricane Sandy mentioned studies that proved a small business was more likely to survive a natural disaster if it worked closely with other businesses. The conclusion was that businesses would provide informal loans to one another to keep everyone afloat until the insurance claims could be processed (which could take months)
The legal system? Shareholders can vote to replace board members.
Not really, obviously I feel more relaxed around people I know but I'm never really comfortable.
If the app cost $1 per year subscription, most people could afford it, but many wouldn't get their shit together and actually do the payment, and then their accounts would be suspended, and the network effect would be reduced.

And also, WhatsApp wouldn't be making a ton of money. Payment processors take a huge bite out of $1 payments, the service does cost money to run, and it costs more money to continue to develop.

A monetization model that's not a subscription allows very poor people/people who are turned off by putting in a credit card number to stay on the system, while monetizing the majority of users for a much higher per-person value, thus meaning that WhatsApp would take in higher total revenue while maintaining their network effect and ability to appeal to new users.

You can see why they want to do the latter.
