fr0sty··on Three Equifax Managers Sold Stock Before Cyber Hack Was Revealed
Someone bought 2500 put options. Each option gives the owner the ability to sell 100 shares at the strike price of the option.

If whoever owns those options exercises them today (And covers their short position at a price of $125) they will make ~$2.5m on a ~$200k bet.

fr0sty··on White House Proposes Slashing Tax Rates for Individuals and Businesses
> The founding fathers enabled the tax.

They repealed the tax 5 years later. Also, it was $1 per $500 (0.2%).

> It was re-instated

as part of the Tax act of 1862 to help fund the Civil War and repealed after the war was paid for.

That history does not scream "must prevent creation of dynastic wealth!" to me.

https://en.wikipedia.org/wiki/Estate_tax_in_the_United_State...

According to the IRS, a temporary stamp tax in 1797 applied a tax of varying size depending on the size of the bequest, ranging from 25 cents for a bequest between $50–$100, to 1 dollar for each $500. The tax was repealed in 1802. In the 19th century, the Revenue Act of 1862 and the War Revenue Act of 1898 also imposed rates, but were each repealed shortly thereafter. The modern estate tax was enacted in 1916.

fr0sty··on Why is this little construction crane illegal in New York City? (2016)
I wonder whether the inventor would have better luck shipping his cranes to another state where the regulatory barriers would not be so steep. Lots of mid/high-rise buildings going up in places that are not NYC...

> do you really want to see what happens when you wrap it around your waist?

The last player on each end can safely wrap the rope around themselves if they like. The rope behind them is slack, so the only tension on the rope is the tension they put on it themselves. Where people get into trouble is when they are somewhere in the middle where there is (significant)tension being applied to their section of rope by people on either side.

fr0sty··on How the Instant Pot cooker developed a cult following
Using the pressure cooker for eggs, aside from making the shells easier to peel, skips the "wait for water to boil" step and gives you several minutes of flexibility at the end of cooking since the heat shuts off when the timer runs out. You can also do large batches of eggs while only heating 1 cup of water.

Does not do sous vide, but it certainly can replace your rice cooker and slow cooker. Only trouble is having only one appliance prevents you from cooking parallel (making curry _and_ the rice to serve it over, for instance, would be a problem).
fr0sty··on How the Instant Pot cooker developed a cult following
Biggest difference between the two is the cooking vessel (Teflon-coated vs. Stainless).

Also, the fact that the Power Pressure Cooker XL is "As Seen on TV!" turns me off personally, but I that may not be a universal reaction.

> The instantpot is a bit slower

Are you pressure cooking your rice or using the "rice" setting? I've found rice to cook faster in this vs. my old Aroma rice cooker...

> Steam escapes noisily through the lid locking mechanism for about a minute first

FWIW, I've found that if you push down on the lid firmly once it starts venting steam in any quantity it will lock instantly.

fr0sty··on Why Some Cars Have Gas Tank Fillers on the Left or the Right
I had an '82 Chevy pickup with that shifter arrangement and it actually wasn't that bad even though the bushings had long fallen out all the joints so there was a good inch of slop in the travel of each of the arms.

Still shifted fine. Unless you didn't get it all the way engaged and the gears would bounce instead of mesh and jam the transmission into 2nd and 3rd at the same time requiring you go get out, open the hood and give the control linkage a good yank before continuing.

Still miss that truck...

fr0sty··on Americans Are Putting Billions More Than Usual in Their 401(k)s
> as recently as 2014 it added $25 billion

Yes, but that is $25B out of total receipts of $884B[0]. For every $1.00 paid in over $.97 was paid back out to beneficiaries. In 2015 it was $.975 and 2016 will probably be higher still.

According to this page[1] the trust fund will be depleted by 2035. I know that is a projection and things can change, but to say there is no room for concern borders on hubris.

0. Remove/disconnect the power LED.

1. Consider powering the sensor via a GPIO pin that you set high when you want to take a reading rather than connecting it to the positive rail.

2. Research whether your chip can be easily put into deep-sleep mode (the -01 boards require a jumper wire to be soldered to one of the IC legs which is not super-easy to accomplish).

Forgive the random comment here, but I just ran into an ancient comment of yours[0] mentioning you searching for a Leader LBO-514a Oscilloscope. Was your search ever successful? I just got my hands on the same model and have been searching for a manual without much luck.

fr0sty··on Why I Would Raise Chickens
Commercial chicken hatching operations separate chickens by sex and destroy the males, yes. Backyard operations rarely hatch their own chicks but rather buy them from suppliers (who deliver via USPS, surprisingly enough).

This is at least in part an editorial choice. Woman throwing grain to flock of chickens running around her feet is a much more interesting visual that chickens walking around foraging...
fr0sty··on What it’s like to be unable to visualize anything
In 1880 Francic Galton did a survey[0] to determine the extent to which different people were capable of mental imagery and he identified much the same phenomenon. Some responses to his questionnaire:

_"These questions presuppose assent to some sort of a proposition regarding the 'mind's eye' and the 'images' which it sees….. This points to some initial fallacy…… It is only by a figure of speech that I can describe my recollection of a scene as a 'mental image' which I can 'see' with my 'mind's eye'….. I do not see it… any more than a man sees the thousand lines of Sophocles which under due pressure he is ready to repeat. The memory possesses it, &c."_

Also related, apparently some people can make it all the way to college without knowing they have no sense of taste[1]:

_"...I was stopped dead by the question of what a peach smelled like. Good. That was all I could come up with. I tried to think of other things. Garbage smelled bad. Perfume smelled good. Popcorn good. Poop bad. But how so? What was the difference? What were the nuances? In just a few minutes' reflection I realized that, despite years of believing the contrary, I never had and never would smell a peach.

All my behavior to that point indicated that I had smell. No one suspected I didn't. For years I simply hadn't known what it was that was supposed to be there. I just thought the way it was for me was how it was for everyone. It took the right stimulus before I finally discovered the gap."

fr0sty··on Banning Some HFT Strategies Helped This Market Grow: Chart
> Just to be fair I think any discrete time auction would reduce HFT.

But is the reduction of HFT qua HFT really the goal? Making a market low-frequency will by definition reduce/eliminate HFT as a strategy but you will still have a lot of trading activity done by well capitalized companies using lots of expensive equipment. They will just use different strategies.

fr0sty··on Banning Some HFT Strategies Helped This Market Grow: Chart
> At least that's what the models show.

What models? Increasing the amount of risk a market maker must bear will widen the quoted spreads not narrow them since that increased risk needs to be priced in.

fr0sty··on Banning Some HFT Strategies Helped This Market Grow: Chart
You only get information directly from the market-center once a minute, but the rest of the world (and other markets which trade continuously, or at a different frequency) are generating new information constantly. Clever and/or well-capitalized participants will be taking advantage of that information in much the same ways as with a continuous market.

fr0sty··on A Traffic Cop’s Ticket Bonanza in a Poor Texas Town
I guess my point is that unless you change the monetary beneficiary of the traffic fines you retain perverse incentives even if you try to make the costs more equitable.
fr0sty··on A Traffic Cop’s Ticket Bonanza in a Poor Texas Town
>seems like it would lessen the incentive to ticket to generate lots of revenue.

That still doesn't align the incentives. It just shifts the focus from quantity of stops to quality of stops (the correlation between vehicle cost and yearly income is very stong).

Law enforcement should not be about generating revenue. Full stop.

All that means is you get to queue-jump when you get to security rather than wait in the longer general queue. The actual security screening is the same.
