But this person was laid off. His help was (apparently) not appreciated, and he's not helping anyone by sitting alone in his car on the parking lot. Do you think it is healthy behavior to go to a parking lot at 0900 every day and do no

As I understand it, there can be concurrent writes as long as they don't touch the same data (the same file system pages, to be exact). Also, the actual COMMIT part is still serialized and you need to begin your transactions with BEGIN

SQlite as a database for web services had a little bit of a boom due to: 1. People gaining newfound appreciation of having the database on the same machine as the web server itself. The latency gains can be substantial and obviously there a

Couple thousand simultaneous should be fine, depending on total system load, whether you're running on spinning disks or on SSDs, p50/99 latency demands and of course you'd need to enable the WAL pragma to allow simultaneous

Regular exams definitely take more than a single hour though. How is this bad?

Perhaps but you while you can maybe predict where the rocket will fall, you cannot reliably predict who it might kill if it hits. People move around and even if you can see it will hit a house for the elderly, you cannot see how many (grand

The energy is not free, since the solar panels cost money and don't last forever. Even at optimistic prices, it's still something like 0.03 USD/kWh. Install them on a boat and they have to deal with constant vibrations, humid

I was bored so I did the math and you are not correct. Even if you don't care about the people themselves, a normal citizen in an industrialized society like Israel has about 40 years of working life. Let's assume for simplicity t

I think what Cantrill is getting at here is that a running program necessarily consists of both code and hardware. If the software is missing, the hardware will be idling. If the hardware is not present, then the software will be just bytes

Yes, I read the article. I still think it's incorrect. Most software (especially by usage) is already not artisanal. You get the exact same browser, database server and (whatsapp/signal/telegram/whatever) messenger clien

This essay, like so many others, mistakes the task of "building" software with the task of "writing" software. Anyone in the world can already get cheap, mass-produced software to do almost anything they want their compu

I know they run truly parallel when they're doing work, but GC still stops the world, right? Assuming you mean "because with Ruby::Box classes and modules have an extra indirection to go though." in the second paragraph, I

I'm kinda hoping that eventually each ractor will run in it's own ruby::box and that each box will get garbage collected individually, so that you could have separate GCs per ractor, BEAM-style. That would allow them to truly run

Nobody in this thread ever claimed it was better for the users. It's better for the people involved in the decision.

The time reported by the "gladvent" package when running with the "--timed" option. AFAICT that does not count compilation (if needed), VM startup time, any JITting happening, or reading in the text file. I'm fine w

I've definitely built the same piece of software hundreds of times over, probably thousands. I've even set up CI to automate the build process. The problem is that the construction equivalent of a software developer is not a trade

Maybe you should re-read the "do things that don't scale" article. It is about doing things manually until you figure out what you should automate, and only then do you automate it. It's not about doing unscalable thin

Oh cool, thanks for providing the correct way around :) Do you know if there is some type of guide around the state machines?

Tigerbeetle is very cool and I would love to see more of it. AFAIR they have been hinting that you could in theory plug in storage engines different from the debit/credit model they've using for some time. Has any of this materi

That is correct.

There are (some) guards available though? You could rewrite your example as: case x { n if x < 0 -> ... n if x > 10 -> ... n if x <= 10 -> ... } Guards are a bit limited in that they cannot c

Gleam is really quite a nice language. I did AoC in it this year as well and came away with the following: (incomplete list for both positive and negative, these are mainly things that come to mind immediately) Positive: - It can be pretty

From the wiki about IEX: "It was founded in 2012 in order to mitigate the effects of high-frequency trading." I can see how they don't want to track internal latency as part of that, or at least not share those numbers with o

"Modern" chess openings are from somewhere between 1860 and 1900. Hypermodern openings emerged after world war 1. One can only imagine what the old masters would call current chess theory.

Kardashev 2 has a Dyson sphere. Of course anything on a single planet can never have that much.
