This is a simulated map based on published transit schedules. As I’m typing this I sit on a bus that’s nowhere to be seen on the map.

I’ve found this article lacking. Like some other articles in this space, it introduces isolation levels through the lens of the phenomena described in the SQL standard, but I find that there’s a different, more intuitive approach.
I think it’s more tractable to define this problem space starting from the concept of (strict) serializability, which is really a generalization of the concept of thread safety. Every software engineer has an intuitive understanding of it. Lack of serializability can lead to execution-dependent behavior, which usually results in hard-to-diagnose bugs. Thus, all systems should strive towards serializability, and the database can be a tool in achieving it.
Various non-serializable levels of database transaction isolation are relaxations of the serializability guarantee, where the database no longer enforces the guarantee and it’s up to the database user to ensure it through other means.
The isolation phenomena are a useful tool for visualizing various corner cases of non-serializability, but they are not inherently tied to it. It's possible to achieve serializability while observing all of the SQL phenomena. For example, a Kubernetes cluster with carefully-written controllers can be serializable.

> Is it just me or is the screen not vertically centered on this device?
It's a 3D render. The actual display seems to be more or less centered[0].
> Also the wake up button is on the left instead of the right
One could presumably flip the device and the rotate the screen rendering by 180 degrees. This is how Apple Watch handles right wrist use.

> There has been no drop in productivity.
As in, your output is the same as with a 5 day work week? So essentially a 20% pay cut per unit of work performed?

This specific problem was already dealt with during the introduction of arrow functions[1]. It makes sense to keep the same parsing semantics.

Wouldn't "Alchemists" fit even better?

> they have yearly CPU instruction limits
This sounded too ridiculous to me, so I started digging. Lo and behold, [1]. Appendix 8, sections 2 and 3.
The entire thing is a fun read, with pearls such as:
in the case of an Intel CPU with either the Sandybridge or Ivybridge
chipset where the competitor chooses not to exploit the AVX feature; the
competitor must explicitly declare and be able to demonstrate that they are
not using the AVX feature in the CFD solve process. If the non‐usage of the
AVX feature is proven to the auditor, the Intel Sandybridge and Ivybridge
chipset cores can be rated as 4 FLOP/cycle/core rather than as 8
FLOP/cycle/core.

Each company C_n would own 51% of the company C_{n-1} (with C_1 being the actual company). At every point each company owns a sizable chunk of equity.

Why would the rice cooker need to be programmed for it, though? For any given quantity of rice, the two variables during cooking is the amount of water and the power of the heating element[1].
It is known that brown rice requires a different ratio of water, but this is something that can be replicated with any method. Does the special brown rice setting change the heat output of the rice cooker?
[1]: Fancy rice cookers use non-constant power, or so I've heard. Not sure how much it influences the taste, though.
