I'm curious about what kind of visualization does the ATC have at the disposal about the current occupancy of the individual tarmac segments? I'd assume if an airplane is approaching for landing on a specific runway, that runway should have been clearly marked as restricted for access until the plane would actually land and clear it?

In the US, airplanes can be cleared for landing while the runway is occupied (you can be number two, three, etc. for landing and still be cleared). It's different in other countries, where you can only be issued a landing clearance if the runway is clear or anticipated to be clear before you land (e.g. the plane before you is already exiting the runway).

Still, the runway could be reserved for landing aircrafts only, still preventing access to all other types of vehicles.

How are fire trucks supposed to respond to incidents involving airplanes, as it appears this case involves, if the runway is off limits to them?

The way it's supposed to work, the ground controller first verifies that there are no traffic conflicts before clearing vehicles to cross an active runway.

Which is exactly what failed here, so saying "it shouldn't fail by not failing" doesn't help terribly much.

Having grade-separate crossings for vehicles might, but that introduces new issues (plane skidding off runway could hit the incline and break up).


O’Hare has those but it’s not helpful for emergencies that happen on the runway itself.

Well, sure, but in that case it's expected that the runway is closed.


After OpenAI?

I assumed Nintendo of America was top.

Can you recommend some brands with good quality over-ear headphones?

As long as it will be pixel-exclusive, it will remain useless to the vast majority of android-capable phone users.


For astronomy bigger pixels is also better.


It depends on sampling and sky conditions. My only point was that some astronomy cameras have smaller pixels (like 1.45um).


Airlines are not public transportation. Usually they're all privatized.

And these additions are the opposite of privatization, they are federal requirements, de facto socialization.


Implementing 'fast lanes' is not a federal requirement and is the opposite of fair access to commonplace services.


The whole thing gave off a feeling that the author was desperate to prove something.


In quantum chemistry, you decide where the bonds should be drawn. Internally, it's all an electron density field. So yes, you can model chemical reactions, for example by constraining the distance between two atoms, and letting everything else reach an equilibrium.


If I'm hiking or cycling alone through the woods with high bear populations, I will often play some music to alert them to prevent an unpleasant encounter.


Nothing about time series-oriented databases?

Not much happened I guess. Clickhouse has got an experimental time series engine : https://clickhouse.com/docs/engines/table-engines/special/ti...


QuestDB at least is gaining some popularity: https://questdb.com/

I was hoping to learn about some new potentially viable alternatives to InfluxDB, alas it seems I'll continue using it for now.


I'm running an experimental side project where I doing some kind of glue between various time-series APIs and storage engines.

For example it has an InfluxDB compatible ingestion API, so Telegraf can push its data to it or InfluxDB can replicate to it. It also has a Prometheus remote read and remote write API, so it's compatible with Prometheus.

The storage can be done in various systems, including ClickHouse, SQLite, DuckDB, TimescaleDB… I should try to include QuestDB.
