> no lockout if you aren't employed anymore

But, I imagine, no stock either?


Why? Whatever's vested is yours.

Not exactly? Options vested is yours to exercise within typically a 60 day[1] window or they expire if you are no longer in the employ of the company.

Exercising your vested options is a taxable event[2] and requires you to upfront some cash to buy the stock depending on what price(and rounds) your options were issued at- this price usually is considerably less than enterprise value of the same share lets say it is $1 and FMV of $100 at the time of issue, however even just $1 for vested 500,000 options is still $500,000 now.

For this simple[4] scenario you need $500,000 immediately to exercise the options into stock before they expire and about ~$13.86M by April to own[5]all stock if ends up say trading at $200 you are worth $100M then.

There are all kinds of funds who would loan you the money or buy the stock off you now on the secondary market, but vested options does not mean owned stock, and selling quickly after exercise is much higher tax under some scenarios.

[1]Some companies have generous(relatively) terms ex-employees to exercise up-to 5-10years later; but it not default in the industry.

[2] This close to IPO that should be relatively small risk; i.e. if the company pulls IPO you still have to pay tax end of the year; if you exercise them.

[3] NSO/ISOs work quite differently, and options vest monthly in most corps and there are lot of creative structures out there; so cannot say how it would be for ANT employee specifically.

[4] Simple - because there usually more than singe 409A valuation and more than single set of options plan issued and plenty of other complex calculus only a finance expert would advise on.

[5] You could sell the shares to pay the ~14M-ish in tax but that could be disqualifying sale(2 year after grant, 1 year after exercise) for ISO meaning you will need to pay effectively 40M tax on your 100M holdings versus only ~$27M otherwise, so you would a take loan against the shares rather than sell to pay the tax.


Wait, I don't quite follow the logic. How is charging car owners (and only car owners) more money the same as investing into auto transport? Does the state have to use the extra money in a certain way?


The money goes to road infrastructure, yes, including a road tunnel they wanted to build under lake Geneva which would be better as a train tunnel.


Great work. I loved the technical innovations.

For the grayscale, I'm guessing each physical display would need to be individually calibrated? I also wonder whether the calibration is sensitive to environmental factors, i.e. gets out of whack if the display is too hot or too cold.


Or with aging.

There has to be a reason the e-ink industry hasn't done this yet...


Maybe not, it could have just been, "Good enough, ship it and move on to the next thing."


I think the standard drivers take temperature into account.


It would be interesting if the driver could sense whether the pixel had fully transitioned or not, allowing it to measure transition time and accurately generate greys.


I have no idea whether it's feasible, but having a direct feedback mechanism would be pretty awesome.


I was thinking some kind of current monitoring on the line. Surely there's some difference in draw when transitioning versus fully transitioned.


But if a display only officially supports black & white, its driver just needs to know the duration of the slowest transition across the operating temperature range. It could then use that duration for all transitions, regardless of the temperature.


For me, the word salad on the front page isn't helping.


Or, as Matt Levine put it, "We will create God and then ask it for money."


Gosh that man has a way with words


That's insane. What type of company are you at? (Or even the actual company if you're OK sharing.)


One that is all in on AI, and wants to be sure its engineers are too.


Ideally one called Jonathan?

"We give a deterministic algorithm that computes the discrete Fourier transform at every length n in O ( n ( log ⁡ n ) ** (1 − 10 ** −13)) operations. The model uses exact complex arithmetic, unrestricted coefficients, specified Fourier roots, and unit-cost logarithmic-size indexing; scalar preparation and array organization are included."


This looks more like word salad instead of any other FFT algorithm paper I've seen, such as the tangent FFT paper that broke the lower bound previously established by split-radix. I'd have to defer to someone who might be able to decode this.
