To be fair, specifically the price is a hidden context passed to every function. Hiding it means the programmer needn't expend effort thinking about it as they would if you did this by hand, but in performance terms this isn't really free.
MDC/NDC only reliably works when you don't have asynchronous code (Akka/Vert.x/CompletionStage) through your application. As soon as you start using multiple threads, it becomes significantly more complex to keep MDC context carried over from one thread to the next.

This is based on the assumption that Rust will make you move more slowly — anecdotally, it does at times — and that this is a constant slow down.

I disagree with that premise. Rust is imperfect, and can seem obtuse when you begin using it. But the payoff is moving faster. It compiles, it works; modulo logic bugs. Less painful refactoring, less time spent chasing memory leaks, none of the bullshit memory bugs, no data races.

This isn't trivial stuff, and pays off day to day.

I also have to object to any argument that says something will be 'automagically' fixed in the future. It's a weak position based on something that _might_ happen.

> The classical logical operators form a neat topology. Should we expect there to be such symmetry and structure amongst the quantum operators as well?

From Quantum Logic https://en.wikipedia.org/wiki/Quantum_logic :

> Quantum logic can be formulated either as a modified version of propositional logic or as a noncommutative and non-associative many-valued (MV) logic.[2][3][4][5][6]

> Quantum logic has been proposed as the correct logic for propositional inference generally, [...] group representations and symmetry.

> The more common view regarding quantum logic, however, is that it provides a formalism for relating observables, system preparation filters and states.[citation needed] In this view, the quantum logic approach resembles more closely the C*-algebraic approach to quantum mechanics. The similarities of the quantum logic formalism to a system of deductive logic may then be regarded more as a curiosity than as a fact of fundamental philosophical importance. A more modern approach to the structure of quantum logic is to assume that it is a diagram—in the sense of category theory—of classical logics

Much more money is "poured into" fission than fusion, likely by a few orders of magnitude. There's one mega project around fusion (ITER) that has a price tag of about 1-2 billion dollars a year if you average it out over the many-decade life of the project, while any given fission plant built also costs billions of dollars.

Like, whether or not fusion itself is a "meme," the idea that we spend obscene amounts of money on it is absolutely a meme with no real backing in reality.

The appeal of fusion is really more about getting out of worrying so much about meltdowns and weapon proliferation, and that there is potential for much higher overall energy output if we can figure it out.

That last bit is why, imo, we should be investing in it now even though it won't really help us reach net zero carbon "in time". If we want to reverse our carbon impact, if and when we get to net zero, we're going to need immense amounts of energy to do it.

I prefer Postgres, and the thing I most envy from Maria is first class bitemporal tables. Granted it took me probably a week curiously returning to the topic to fully grasp their value, and I don’t think I’m alone in that lack of immediate intuition. And granted non-SQL databases like Datomic are much better positioned for use cases where people realize they want the feature. And granted it definitely can’t be more storage efficient to store bitemporal data than not to. But I think it’s a much more compelling feature, from the outside.

As far as memory complexity, this got me thinking a userspace implementation (I’ve prototyped one for Postgres using VIEWs for fun and personal education) could reasonably borrow optimization techniques from persistent data structures common in FP languages. But I don’t know how well a query planner would cope with that, and my instinct is that the optimization would be better applied at the storage engine level (again as I see it, advantage: Maria).

I see it the other way around: tracing is essentially logging with hierarchy. If you can keep the context of a "parent" span around, then you can log all of the entries out and build up the entire trace from spans, although you can get pretty confused if you don't write them out in the correct order.

However, if you don't have context, then the log entry is the atomic unit -- metrics are log entries with numbers that can be aggregated, spans are log entries with a trace id and a parent span, and "events" in Honeycomb terminology are logs with attributes covering an entire business operation / HTTP request.

Opinion: High density planned communities that try to take care of almost everything, like you describe, are a at serious risk of being insipid, mediocre, uninspiring, and worse. I think it’s something about the incentive structure, probably, but this is largely an empirical opinion; in my experience it’s just far better to live with a diversity of landlords in the area. New York has a great set of examples: A neighborhood like SoHo or Hell’s Kitchen or the Lower East Side is a magnet. An overproduced condo/office/retailplex like Hudson Yards, without much competition next door, is dull and insipid and soulless. A big complex like Rockefeller Center is actually kind of okay — because it’s embedded in a neighborhood where everyone has a dozen dozen places in a five minute walk they could go to instead.

Well I will say:

Airbags have about 2 feet of "cushion" to catch the driver. A "Bedroom Airbag is going to have more room and time to inflate. Also, I suppose you could strap yourself in. And RVs have a lot more momentum and are inherently safer in crashes, kind of like how schoolbusses don't have seat belts.

As you alluded, you could have a "safety blanket that is normally loose but tightens on impact.

Finally, typically head on crashes are the danger for RV, and the bed is in the back, so that is a gigantic amount of the vehicle to absorb impact and damage.

automation makes both easier to deal with.

"Mean time to repair" is all fine if you don't have to drive 30 minutes to datacenter to swap out stuff.

Even if its cloudy cloud and you have backups, restores can take a lot of time.

Also you will want HA when it's your internet gateway to die

There are also levels of implementation. Making fully redundant set of loadbalancers is relatively easy. But any stateful app is much, much harder.

My RDBMS course at college was really hardcore and SQL code answers for exam questions were enormous.

This way you can decompose very complex queries into simple ones, that can tested independently.

However, as a stickler for quality, I find myself on the wrong end of this discussion in practice. I insist, logging is truly the LCD of software development. Introducing unergonomic data structures generated from protobufs strikes me as something that the long tail would ignore, and instead simply reach for something simpler to instead log `here`, `here1`, etc.

I disagree that it needs "help", which suggests that there is something fundamentally wrong with SQL that needs to change, possibly with help from outside of the SQL community.

> Build a monolith as microservices.

See also, Boundaries[1]. Apologies, I still can’t find a transcript since I last linked to it. The general idea is to write most of your code as functional and isolate small parts to handle state.

I will say I do think money has been spent unwisely on fusion, particularly on approaches that have very little chance of success, with programmatic dysfunction that even fusion advocates have noted with anger.

In my experience that hasn't worked out. Being invaluable just means more pressure gets piled on you, and any reward or leverage you think you might be getting in return doesn't materialise. The credit you earn doesn't translate into anything tangible.

Re: Comptime interfaces

I wonder why Zig didn't decide on the convention of making the allocator type comptime-known. It would make code faster by eliminating a runtime indirect call, and it would let you lower memory usage if you choose a zero-sized type as your allocator, since e.g. every single ArrayList in your app would no longer need to reserve space for the allocator field.
Our biggest project (with a bunch of different infrastructure stuff) is also one with the least time spent per instance). We have months where no ops even logged on their VMs.

Our highest maintenance stuff is entirely "the dev fucked up"/"the dev is clueless". Stuff like server deciding to dump gigabytes of logs per minute or run out of disk space coz of some code error. Only difference compared to k8s is that the dead app would signal dev first, not actual monitoring we had.

And honorable mention for WordPress "developers" that make the first place in "most issues per server" every single year. And we have very few WP compared to everything else. Stuff like "dev uploaded some plugins, got instantly hacked (partially, we force using outgoing proxy and that stopped full compromise), we reverted it, he uploaded same stuff and got hacked again". So, nothing to do with actual servers.

Stuff like setting up automation to deploy ceph cluster took some time... once. Now it takes nothing. We even managed to plug it to k8s cluster.
