Pre Close:

- From Bloomberg re Robinhood and TSLA "number of Robinhood accounts holding Tesla shares (in some form) is at an all-
time high of 496,890. Tesla is the second-most popular stock on the
platform over the last 24 hours, and the 19th-most popular stock over the last 7 days."

Looking at:

- if profitiable check for amount of regulatory credits that Telsa gets from other automakers,
this could be the difference between profitablity and not, though if this is what puts them over them
edge then be a bit concerned

- Is Texax truck factory happening or not? If so, what kind of tax incentives did they get as
these types of tax deals are the first thing that could get cut if reports of Texas', um Texas sized,
budget gaps exits, Tulsa is the other option, maybe with the SC ruling Tulsa is native land there could be some
weird tax deal there??

- Tesla's capex was cut way back from almost $3B forcats to under $1.3, helps make them look profitiable last year
at the expense of that having to be made up this or next year, look for capex to be much higher

- Model Y and X and S are only made in Fremont, though Shanghai will start producing the Y soonish, still lots of
geographical risk as the pandemic and factory shutdown illustrated, Musk must do better here

- Model Y was discounted and its brand new, Model S and X were discounted as well, TSLA really pushing to make
their quarter for cars delivered, watch for gross margins to be down but numbers to be very juiced for a large beat

Numbers:

- Rev $6B vs $5.5B, down from previous highs, but with teh lock down, pretty darn good!!

- profit of 50cents per share on a GAAP basis, nice, though credits really juiced this

- 4 quarters of profitability, though not always pretty or organic is really nice to see

- Net Income was $451M vs ($74M), nice but mostly a factor of major discounting of cars and credit sales

- Cash and cash equivalents @ $8.5B, nice!!!

- Solar, yawn, 27 MW installed, why even bother at this point?

- handed over 90,000 vehicles, different from produced

Outcome:

- market cap is now $320B, wow!!

- stock is flat on day as one would expect with so much vol leading up to announcement. The Post earnings drift traders are probably staying away as you need nerves of steel to trade TSLA earnings:)

- Musk is now able to exercise an additional 1.69 million stock options, meaning he would reap a $2.1 billion gain if he exercised and could immediately sell the shares.

- S&P 500 here we come, so /r/wallstreetbets and robinhood, congrats you guys did it!!!
Given their net income is positive, what is the probability that they are added to s&p500?
Semgrep's pretty slick. I tried out a demo and I was pretty blown away by how I could essentially just guess my way to a signature.
Sounds like a recipe for a chilling effect to me. Why risk being denounced? Just shut up and never interact with anyone in any way that others could use against you. As a society we need to enforce norms that protect everyone's ability to operate in good faith. If a person or an organization doxxes someone or publishes information against their expressed wishes without a clear moral obligation to do so then they should be held accountable. I'm hoping that this case has garnered enough attention that the pressure is being felt by the NYT and others.
Disagree. If someone's choice either is to work for G, or start the company, it is the founders risk to take and give up that job for the outsized risk and return of starting up. It is not YC's need to compensate a founder for their alternative.

> can limit access to the Global except in very desirable patterns

It’s desirable when you don’t do much I/O, only implementing some algorithms that compute something.

It’s not desirable at all when the majority of your complexity is I/O. An extreme example is a videogame, these can update global mutable state (the VRAM, abstracted behind GL or D3D) with the bandwidth measured in gigabytes/second, often concurrently so from multiple threads.

Update: and even for computations, when you want performance, rust’s ownership shenanigans often get in the way. See this C++ code for example: https://github.com/Const-me/SimdPrecisionTest/blob/master/rc... You gonna have hard time porting that to Rust, because this vector https://github.com/Const-me/SimdPrecisionTest/blob/master/rc... is updated concurrently by multiple threads of the pool, without any locks.
I don't consider having the ability to edit a document collaboratively contradictory to the document use case. Sure, the editing plumbing is an app, but the core of it is still a document. Contrast this to something like a game or a web shop, which gravitate much more distinctly towards the app use case. Someone else mentioned how the web was envisioned to be editable from the start.
This is really nice!

I wonder if some of the cli commands like create can be auto-executed on first git push.

Is this open source? Would love to hack onto it.
I'd love some examples of real-world design docs.
> They are only doing this now because ...

Apple announced these devices last year at Black Hat.
Yes, I'm aware of this little nuance - I've been through startup equity meat grinder myself. It's too complicated to quickly explain to a layperson though, and deliberately so. Many people are working for startups not knowing that they'll get bupkis if those startups succeed. I'd venture to say easily the majority. Many founders on HN try to pretend they won't negotiate their often abusive equity offer terms with their best employees (a lie - they will) because that requires "board approval". Most of them are also not huge fans of prospective employees hiring a lawyer to review the equity offer, to at least understand how the employee is being screwed.
It's easy to find many countries with much worse social nets than the USA, but with worse entrepreneurial outcomes. The social net versus entrepreneurial outcome function might not be a monotonically increasing one.
Assuming your developers have malicious intent is a bit strange for me personally. But I get that some companies may have this structure in place.
How is this different than a security through obscurity argument which is so roundly discounted by virtually everyone who reads HN?

I read and work with JSON all the time, logs, responses, code generated from json data. The format suffers from not being readable because of the quotes issue. Especially when what you are putting in there has quotes, the amount of escaping required is ridiculous.

{"time":"2020-07-22T10:59:14.95406-04:00","message":"{\"level\":\"debug\",\"module\":\"system\",\"time\":\"2020-07-22T10:59:14.953909-04:00\",\"message\":\"Running MetricCollector.Flush()\"}"}

this is a very moderate example of what I deal with daily, all because JSON includes quotes around fields.

Point being - there are a lot of factors outside of one's control that affects one risk adversity

* having a place to live if you go broke

* a place within some manageable travel distance ( i.e. same state/country/continent )

* a place where you will feel a warm sense of welcome

* a place where you will have creature comforts: a comfortable bed, a private room, an bathroom with minimal wait times

* a place where you don't need to contribute to living expenses, at least not right away and not until you can get back on your feet

* a place which is a good launching point for your next career

* (US) health care

Successful founders I know have all of these - every last one.

A floating point add works roughly like this:

0. Extract mantissa and exponents from the inputs [basically free in a HW implementation].

1. Combine the two exponents and shift the mantissas so that they same the share scale.

2. Add the two mantissas together.

3. Normalize the result back into a floating-point number.

Now look at the process for a floating-point multiply operation:

0. Extract mantissa and exponents from the inputs [basically free in a HW implementation].

1. Add the two exponents together.

2. Multiply the two mantissas together.

3. Normalize the result back into a floating-point number.

Steps 0 and 3 are identical in both cases. I'm not really knowledgeable about hardware multiplier implementations, but doing an additional "add" operation can be pretty close to free in some implementations. In any case, adding in an extra adder to the process is going to be quite cheap, even if not free.

What this means is that there is not much extra hardware to turn a FMUL ALU op into an FMA ALU op... and if you make just a single FMA ALU op, you can use that hardware to implement FADD, FMUL, and FMA with nothing more than microcode.

In other words, instead of thinking of FMA as something worth pouring more resources into, think of it as FADD as not worth enough to be made its own independent unit.
Care to elaborate on what "rich with availability bias" means? I've never heard that one before.

Also, the individual in reference wasn't the of the gender you're assuming.
"otherwise they are a founder and should be rewarded accordingly with equity."

Of course - as they were. My point was on cash money comp. Never said they worked for free hence their title of technical cofounder which implies equity.

"...and actually be effective at it is extremely rare. What you'll usually find is someone at the beginning of their career that doesn't really understand what they are getting into."

The onus is on the founding team to be sufficiently compelling to attract such a rare breed and if they execute correctly there is no short end to the stick to be had.
All those 'limitations' are too much anthropomorphic for my taste - life can probably exist in far more niches.

Also, at our current tech level, planets are very hard to even observe for existence, let alone their geographical features.
There's a fair amount of manual data collection. I get an excuse to enter into e-mail correspondence with 100s of writers each year, although I have most of the initial contact programmatically driven. There's also automatic annual e-mails of program directors in August to get the latest data from them and for the top schools on the list, I'll make calls if they don't answer the e-mails. In the fall I end up spending an hour or so a day dealing with all the e-mails and data entry.

Yes, to an extent, but the case is not closed by any means. From memory, the logical error rate target is 1e-12. Clearly, quite a
sizeable leap of faith is needed to extrapolate from the Martinis results to this value.
That's crazy! The large lag between clicking and the UI updating is slightly annoying, but that's just me nitpicking at something other than the cool technical feat.
"hipster keto" - - exactly.

I converted over to 30% monkfruit extract powder as a sweetener, no bitter aftertaste, the closest to sugar I have ever tasted, ~$210 a kg., stored in my freezer it will last me 5 years.

It's like 200x sweeter than sugar and has almost zero calories and FDA approved. I can achieve up to a brix level 8 with monkfruit, so it will not sweeten very sour or bitter substances by itself. Some mix it with erythritol to get closer to sweetening bitter chocolate.
My security model actually is “I don’t trust myself”.

One of the obvious conclusions from modern security research is that the user has become the number one vulnerability in pretty much all systems.

The corollary that a lot of people miss is that developers and security researchers are users too. They get pwned too. They some give the wrong permissions to an executable.
I should also point out that this is a common misconception for hardware/solution companies. Very hard to make enough money to fund R&D with consulting. I did that for the first 4 years of the company.

Put bluntly, that model, the consulting bit, is not for the faint of heart. It is just as hard, as in you absolutely have to hustle hard this whole time, to get business. Leaving you with precious little time to develop your ideas.

I've lived it. I don't recommend it, without a partner with a strong income. My wife was a stay-at-home mom for part of this time, and worked at a school as a teacher. Not sufficient income to live off of for 1 person in a house with a mortgage. Nevermind a family.
> Are you going to be charging me less if Apple gave a discount on your app commissions?

Not necessarily, but developers will have a higher margin, which will allow them to continue developing their apps and increase their quality, because they don't have to waste their time thinking about X ways to increase their tiny margins of the product, so they can survive for a little bit longer.

>App developers are highly likely to claim that the platform is monopolistic because they would benefit from such a decision.

Apple is highly likely to claim that the platform is not monopolistic because they would benefit from such a decision. See? the statement can be easily inverted, again it's a vacuous statement. Is their behavior anti competitive and in violation of the spirit of the law? That's the essential question.
The difference in the narrative versus the financial data is stark:

Quarterly revenue has not shown any growth for nearly 2 years, despite introducing more models and expanding global deliveries. Their sales of regulatory credits this year is greater than all of the net income ever earned in their entire history.
HackerNews is a limited-focus link aggregation and comment platform. It doesn't require the kind of moderation that larger scale, broad-focus social media platforms do.

I don't envy the work that Dan and Scott have to do in the slightest, but I don't think they'll end up with PTSD from it. At least, that's what I gathered when I read "The Lonely Work of Moderating Hacker News"[0], especially this description of it: "Pressed to describe Hacker News, they do so by means of extravagant, sometimes tender metaphors: the site is a “social ecosystem,” a “hall of mirrors,” a “public park or garden,” a “fractal tree."

Hmmmm it's probably best demonstrated with an example: if you have users a b and c, a normal rotation of a chore would be a b c a b c a b c ... and so on. If user b has 2X, the rotation would be a b b c a b c ... Does that make sense?

Assignment and rotation happens automatically. A chore is setup with a frequency, etc, then as users are assigned they are notified and they only need to intervene when they do the chore.

TL;DR: for optical wavelengths, with typical image sensors that only detect amplitude and not phase of the electromagnetic wave, you need to do some really hard work to ensure optical coherency. For radio telescopes, it's a lot easier since you measure both amplitude and phase.

Another technique that's a lot easier to accomplish for amateurs is lucky imaging:

Yep - that's life. It's called 'the choices we make close doors'. Responsibilities we take on, have repercussions. Founders with such obligations can work at home after their job like every other person starting a small business that is not tech. That way they have infinite runaway, and personal life stress, but not 'monetary stress'.
Whose isn't?
Part of the point of security research is that practically 0% of consumers are capable of doing this research themselves and making informed purchasing decisions. Security researchers hold businesses accountable when consumers can't.

In light of that, your argument is "Just don't hold Apple accountable!", which Apple would love... but that would also be harmful to consumers.
Beware of the job market. If you can't find a job when you graduate next year, you get to go into the horrible "haven't had a job since I graduated X months ago" which can turn your resume into poison for quite a few industries.

We're using Heroku where I'm at and looking to move off of it for a number of reasons. Review apps are one of the great things about Heroku, but once your team is above a certain size its most definitely not free, or even cheap.

The biggest pain point I'd like to see solved (beyond just review apps) is the provisioning of good staging data. Ultimately we want data that looks like a subset of production data with PII scrubbed. Heroku doesn't give you an easy mechanism for getting this, and we had to sink a ton of time building this out for our specific use case.
> A wealthy black person can easily start their own business.

Certainly, but black people are disproportionately less wealthy than white people, so are far less likely to be in that position.

> A poor white person cannot use their whiteness to pay the bills.

This is also true, but they will not face the structural racial discrimination that a black person of their socio-economic standing would.

The trouble with reducing issues of inequality to class alone is that it obscures the systemic biases that make it easier for white dudes to become rich in the first place.
>if profitiable check for amount of regulatory credits that Telsa gets from other automakers, this could be the difference between profitablity and not, though if this is what puts them over them edge then be a bit concerned

$400MM+ in regulatory credits.

GAAP Profit is around $120MM so far in 2020, with almost $800MM in credit sales. Crazy.
What are regulatory credits? I thought the 7500 credit ran out?
I think things are more complex than "brushing and flossing damages your gums depending on force and utility" because I've got wisdom teeth that I've been forcibly brushing for decades in the interest of making my gumline recede and it just. doesn't. work.

I also eat carbs like they're going out of style. At least one serving every day, minimum. I've also had an insatiable sweet tooth for most of my life, although that tapered off into my mid-30s.

I went fourteen years without seeing a dentist, and when I finally went in, aside from serious plaque buildup, my teeth and gums were in fantastic shape. It may have something to do with the fact that I drink skim milk like a toddler - about two gallons a week.

I will say, one effect that dairy and carbs has on my oral hygiene is that they promote the formation of tonsililoths - but once I was turned on to using a tongue scraper, that problem disappeared completely.

How did I go 14 years without a dentist and end up with great teeth anyway? Avoid sugary carbonated beverages, I floss with Plackers, I brush daily with an electric toothbrush and a baking soda/peroxide toothpaste, I use a tongue scraper, and I rinse with & gargle Listerene.
> The issue is that the universe is extremely old compared to how long it took for earth to develop life

I wouldn't call the universe very old. It's only like 13.x billion years old. If you take into account the amount of time it takes for heavier elements to be created, the time for the universe to settle down I'd say we are in the first cohort. It took us 4.5 billion years to evolve and if humanity got wiped out life on Earth would most likely continue on as it has for millions of years before with megafauna.

Looking at how life appeared immediately after the planet cooled down and had liquid oceans most likely indicates abiogenesis is common, multicellular may be much more rare and intelligence probably is exceedingly rare given how expensive big brains are. I just don't think there was enough time in the early universe for intelligent civilizations to have evolved.
