This lunch is 500 yen ($4.80) at Sukiya, a Japanese fast food restaurant which belongs to a category with about three big competitors.

I love the aesthetics of this category and they’re under remarked upon.

I think people underestimate QSRs in terms of social utility, but Sukiya et al describe themselves as mission-oriented enterprises. I believe this is largely sincere, and goes back to the 60s and 70s, when the clientele was primarily manual laborers who had migrated to work.
Japan was not a rich nation at the time, and day laborers in particular were both unlikely to be able to cook for themselves and unlikely to have much of a food budget, and so the chains sprung up offering an honest-to-goodness cooked meal delivered in under a minute for cheap.
This heritage continued over the years, even after Japan became a much more wealthy nation, and these chains function as social support and dignity for folks in diminished circumstances.

They also are a wee bit of a cartel, and I appreciate the aesthetics of the cartel:
Back when I was first in Japan, in the mid 2000s, there was an increase in the price of beef.

And the heads of the three chains got together, and decided that the price of the basic beef bowl needed to increase, but given the economic circumstances how could they hold the line.
And what they came up with, from memory, was:

“We are very sorry, given the economic environment, to raise the price from 165 yen to 180 yen, but we are doing our level best to keep it there, and have mutually decided that approximately one yen of margin is appropriate.”
(That dish is, 15 years later, about 350 yen here. I thought there was a +/- 250 yen option still available, and the mini size is around there, but historically the political economy of the dish was based off that offering. I’m slightly disappointed seeing it at 350.)
Oh a fun foodtech (really!) thing I wish caught on more in the US:

If your offering is “I plate a bit of five big pots of things I cooked in the morning and keep heated as serving temperature all day” you can get the offering almost arbitrarily cheap.

Explains bowls, curry, etc
It doesn’t take more training to prepare rice than it does to prepare a McDonalds burger but by definition the only thing in rice is rice, and the only thing in the egg is egg, etc. (There’s a bit of seasoning/sauce on the beef, prepared centrally. Only prep here is heat + plate)

I like this heuristic, and have a few which are similar in intent to it:


Hiring efficiency:

How long does it take, measured from initial expression of interest through offer of employment signed, for a typical candidate cold inbounding to the company?

What is the *theoretical minimum* for *any* candidate?

How long does it take, as a developer newly hired at the company:

* To get a fully credentialed machine issued to you
* To get a fully functional development environment on that machine which could push code to production immediately
* To solo ship one material quanta of work

How long does it take, from first idea floated to "It's on the Internet", to create a piece of marketing collateral.

(For bonus points: break down by ambitiousness / form factor.)

How many people have to say yes to do something which is clearly worth doing which costs $5,000 / $15,000 / $250,000 and has never been done before.
So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.


The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.

This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.

The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."

This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.

"Suprise, Kacchan!"

Izuku happily wiggles, hopping from one foot to the other like an excitable toddler, despite the fact that he's 6 foot something and a venerable powerhouse of a pro hero.

In his hand is a plate of… something… messy from each edge.


There's a message written on top in some sort of sauce, but the sauce had gotten absorbed in the rice. The mishmashed mush of vegetables (?) kind of looked like something you would pull out of a shower drain.

But the meat looks good? Browned chicken, maybe a little overspiced.

"The hell's this?"

"I made you dinner!" Izuku ushers Katsuki towards the dining table, hardly letting him take off his jacket first.

As soon as Katsuki sits, a napkin gets shoved in his lap as if they're at a fancy restaurant. Izuku becomes a whirlwind, flitting this way

and that in their home until there are a number of candles lit.

It would make the ambiance more romantic if it wasn't still daylight outside. It was closer to lunchtime than dinner, but Katsuki would let him have this.

He, instead, stares down at [the meal] and carefully schools his features. He isn't sure if he looks deadpan or intrigued like he means to, because as soon as he looks close, the veggies /jump/ on the plate, bubbling like they're still boiling.

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

https://t.co/FBfXhUrH5d


Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
