yau8edq12i··on CSharpRepl: C# REPL with syntax highlighting and intellisense
What do you mean? With dotnet fsi? I just tried it and it reads UTF8 just fine, at least in windows terminal.
yau8edq12i··on BB(3, 4) > Ack(14)
The initial state is A, the tape is full of 0 (on both sides).
yau8edq12i··on BB(3, 4) > Ack(14)
Infinite tape of zeros.
yau8edq12i··on How to compare two packed bitfields without having to unpack each field (2019)
Based on my quick and dirty benchmarking, it's similar in terms of performance. The vector comparison is consistent, the unpacking comparison is about 1.5x faster if it can exit early, but 4x slower otherwise. Here are the results: https://pastebin.com/QL4sNzhj (the code is straight from the article, the benchmarking done with google benchmark).
yau8edq12i··on What's the difference between a motor and an engine? (2013)
Fun fact: the French word engin still retains its original meaning of contrivance, contraption. But we still translate "search engine," which refers to this archaic English meaning, as moteur de recherche ("search motor").
yau8edq12i··on The Denmark secret: how it became the most trusting country
It's funny how little time it takes to go from "cultural" to "ethnic". Say what you think instead of using whistles: you think that Denmark conforms to your racially focused worldview, that it's "pure", or whatever. Am I correct?

Funnily enough, Denmark is a few places below France in "ethnic fractionalization", yet somehow, racists worldwide insist that France has become a shithole because of immigration.

yau8edq12i··on How and why to make a /now page on your site
What do you mean by "for reference"? That URL is feature prominently in the linked blog post.
yau8edq12i··on "No way to prevent this" say users of only language where this regularly happens
I program MCUs as a hobby. I wish I could use something better than C. Even C++ with RAII would be better. But somehow, even C++ support is spotty, with unsupported features, broken debugging, etc. for seemingly no reason. And all device-specific libraries are written in C, so I'd have to write C++ wrappers for every little thing. Send help...
yau8edq12i··on Amber: Programming language compiled to Bash
It's not much of a "runtime", though. How is it better than a plain executable?
yau8edq12i··on Amber: Programming language compiled to Bash
I guess I don't understand the point. Could someone summarize why I would use this rather than writing my utilities in something that doesn't compile to a quirky, limited programming language?
yau8edq12i··on US Companies Move Behind American Shield to Delay Global Tax
As usual, the US plays lone wolf and screws its "allies" over. We have a saying in France: promises only bind those who believe them. I'll belive the US is actually intent on curbing global tax evasion when I see it.
yau8edq12i··on Grothendieck’s use of equality
Uh... I have a PhD, I'm a tenured professor, and I even supervise a couple of PhD students. How about you? Given your snarky tone, it sounds like you'd have mentioned something like this. Not sure why you'd try to flex when you don't know much about me ;)

With my font, the letter l looked like a vertical bar |. Hence why this looked like symbol soup. But okay, let's say it's about projective spaces. Then surely, you realize that the equal sign still denotes equality. The point [1:2] is literally equal to [2:4] in P^2, not "proportional". Perhaps you need a refresher: https://en.wikipedia.org/wiki/Equivalence_class#quotient_set

yau8edq12i··on Grothendieck’s use of equality
... What? That's just symbol soup. What are you trying to write? Do it in latex if it helps.
yau8edq12i··on Big Tech to EU: "Drop Dead"
> "Initiating legislation" for example, is just another way to say "decide what the law is".

It's not.

> It can only acquiesce to or slow down the Commission's decisions.

That's not all it can do.

yau8edq12i··on Grothendieck’s use of equality
How can you frame a paper from 1965 as "very old" when the linked article is about Grothendieck, who started his math PhD in 1950 (and presumably studied math before that)?
yau8edq12i··on Grothendieck’s use of equality
As a mathematician, I have never, ever seen the equal sign used to denote proportionality. I cannot tell what you mean by "identity" that wouldn't be equality. And a definition in the sense you seem to mean is, indeed, also an equality. I guess this issue not mentioned in the paper because it doesn't exist.
yau8edq12i··on Grothendieck’s use of equality
I think it's the first time that I witness this comic https://xkcd.com/793/ happening but with math as a target.
yau8edq12i··on Migrating Uber's ledger data from DynamoDB to LedgerStore
Forgive me because what follows will sound harsh, but I think you need to hear it based on your response.

> HaystackDB is designed from the ground up for write intensive workloads

Okay.

> so it’s much more economical than existing off-shelf-solutions for that type of workload.

That's a leap in logic. Just because you designed it with this workload in mind, well, doesn't automatically mean that it's any good for this workload (or any workload). If solving a problem was as easy as declaring "I will design my solution from the ground up for this problem", then we'd all live in peace and harmony. So that's what people are asking you here: how do you make your DB "much more economical" for that type of workload? What technology, what ideas have you had to make it possible? If you don't want to reveal that, then you need proof that it's better than the competition, not a declaration, that it's better than the competition.

> Is that not clear from the landing page?

It's clear that you want to market your solution as something good for write-heavy workloads. Why should we believe you've done a good job designing your solution?

> From pricing: “$0.2 per million writes, $20 per million reads”. The typical cost profile is $2 per million read/writes, or even more for writes.

Who knows how you came up with pricing? Perhaps you're betting on your customers being stupid and not realizing that taking a 10x hit on the price of reads will lose them (and earn you) more money in the long run. After all, what good is writing to a DB if you never read from it...? Or perhaps it's some kind of promotional / loss leader pricing that will change soon in the future. In any case, it's, again, not proof that your solution is adapted to the customer's problem.

yau8edq12i··on Discussion: Job seekers can't find a job and Employers can't find an employees
Even a single person can be hypocritical or self-sabotaging sometimes. And "an employer" is often not a single person but an organization with a bunch of people pulling in different directions. Some people making hiring decisions or deciding on hiring procedures may not necessarily care about the procedure being "bad". Maybe they e.g. care about maintaining "standards" or whatever justification they came up with.
yau8edq12i··on Big Tech to EU: "Drop Dead"
At first it was "making decisions", then it was "initiate legislation", and now it's "decide what the law is". It's tiring to argue against moving goal posts and bad faith. Besides, the first sentence of a Wikipedia article is not the ultimate, complete and exhaustive definition of what something is.

> Something that cannot decide what the law is

Good thing the EU parliament decides what the law is, then.

yau8edq12i··on Men's Shirts Button on the Right. Why Do Women's Button on the Left?
Seriously? In my experience, having lived in several places in Europe and in the US: Americans like to pretend that calling it "pop" or "soda" depending on where you are in the country, or Chicagoans having a deeper pizza while food in the bayou is spicier, or Californians liking surf while Iowans are into hunting, constitutes fundamental differences. Meanwhile, they all share the same overall culture: same language, same tv shows, same movies, same school systems, same university systems, same sports, same music, same historical figures and references, same laws, same political figures and topics... There are slight variations here and there, of course; just like in any European country. But ask a Hungarian and a Spanish person if they watched the same shows as kids or learned the same stuff in school, and see where that gets you. Most Americans I've met take their country's cultural baseline for granted and magnify the slight differences among themselves.
yau8edq12i··on Big Tech to EU: "Drop Dead"
I wasn't aware that "make decisions" meant exclusively "initiate legislation". You don't have to play coy, though: it is also middle school level knowledge that the parliament cannot formally initiate the legislative process. It's also written in the Wikipedia article I linked.

> The European Parliament has legislative power in that the adoption of EU legislation normally requires its approval, and that of the Council, in what amounts to a bicameral legislature. However, it does not formally possess the right of initiative (i.e. the right to formally initiate the legislative procedure) in the way that most national parliaments of the member states do, as the right of initiative is a prerogative of the European Commission.[7][8] Nonetheless, the Parliament and the Council each have the right to request the Commission to initiate the legislative procedure and put forward a proposal.[9]

What is your conclusion from this? What point do you want to make? Don't leave your readers guessing.

yau8edq12i··on Big Tech to EU: "Drop Dead"
The EU parliament can absolutely make decisions. https://en.wikipedia.org/wiki/European_Parliament#Powers_and... This is middle school level knowledge...
yau8edq12i··on Men's Shirts Button on the Right. Why Do Women's Button on the Left?
The USA is much, much more homogeneous than Europe.
yau8edq12i··on Men's Shirts Button on the Right. Why Do Women's Button on the Left?
Eastern Europe, Northern Europe etc are not "continental"? That's weirdly reductive.

yau8edq12i··on LoRA Learns Less and Forgets Less
Yes, you got the joke.
yau8edq12i··on The case against dual axis charts (and what to use instead) (2018)
Fahrenheit is not an absolute scale, so there is nothing special about 0F, you're right about that. As for your other two examples (atmospheric CO2 and stock tickers)... Yes, the scale should start at 0. Why shouldn't they?
yau8edq12i··on Non-Euclidean Doom: what happens to a game when pi is not 3.14159 (2022) [video]
Have you actually read recent SF novels? Think what you will about awards, but I've never been exceedingly disappointed when I read a novel that won a couple out of Hugo, Locus, and Nebula. I'd suggest you start there.
yau8edq12i··on Deutsche Bahn introduces "MetaWindow"
A decades old national train company is about as far from a startup as can be. That's a really strange comment.
