I disagree. I'm an observability geek, and OTel is... fine. It's missing a few things that I'd like, but I was able to implement them myself. I guess the major design issue is that the sampling decision is made at the _start_

> A typical jaguar Waymo usually carries up to 4 people (usually just one), weighs 2.1 tonnes and is 5.2m long. A more reasonable taxi for single riders is going to weigh around 1.5 tons (e.g. the prototype Tesla Robocab). You also incor

And this is a fundamental issue with transit. It _has_ to travel as mostly empty on avereage to be useful.

Yes? Why is this strange? Drivers emit a lot of CO2, just like every person in the US. A driverless car allows these emissions to be reallocated to other more productive areas.

An average bus load in the US is around 18 people. So if you just compute the raw bus emissions, then an electric bus is maybe about 2x more efficient than personal EVs. But wait, there's so much more! A single bus/subway ride cos

Buses and subways are not necessarily "greener".

To be more precise, we tax (or cap-and-trade) pollution. For example, sulfur emissions and, in some countries, CO2 emissions. > Also should all work sites be taxed, or just "office" ones? Dense offices in downtowns.

I will keep repeating this and I will keep getting downvoted for that. You can't out-build yourself out of high living costs. The only way to fix this is to start taxing dense office space as if it's toxic waste sites. And promote

Yup. Still, it's less than their annual income by several times.

Sure. But you might not even be realizing that something is just at the cusp if the load is spiky enough. The art of large system design is to identify and avoid these kinds of chokepoints. And when something happens, propagate the "ba

A server box now has around 256 CPU cores. So that's about 12000 servers. If each one is $10k that's $120 million. Not a lot compared to Github's income.

The computational complexity is a bit of a red herring. Finding the most optimal solution is hard. But if you settle for a close-to-optimal solution, then it can be solved in a much more reasonable time.

This absolutely can happen in large systems. If some part of the system is at capacity, then slightly increasing the load can cause it to fall behind and start accumulating a backlog. These backlogs can cause clients to make more retries, e

VxD-s technically allowed virtualizing devices, but only in a very limited way. The port IO instructions were easily intercepted but not much else. VxDs could use page protection tricks to redirect MMIO but this was used sparingly. Really t

Our favorite WebAssembly is an example! It specifically excludes trigonometry from the spec, because real hardware doesn't produce exactly the same results. So mathematical libraries in WASM reimplement the trigonometric functions usin

It was not a hypervisor, the hardware was not virtualized. They instead used 16-bit code for the OS kernel, simply transitioning between 16 and 32-bit modes. The 16-bit code was a dead end. It was not re-enterable, so 32-bit code had to ta

Physician/nurse salary is not the major driver of the cost of healthcare. It's around 12-15% spending, depending on the methodology. Even if you force doctors to work for free, it won't meaningfully affect the cost. It's

Insurance prices _dropped_ in NY after the ACA was enacted. Not "slowed down the growth" but actually dropped in absolute numbers. That's because NY had enacted a coverage mandate even before the ACA, so insurance companies w

We do it just fine (not for games). You submit a new binary for review in advance and then do a coordinated release once the review completes.
