junippor··on Tesla orders its first 8k-ton Cybertruck casting machine
Wait..... they're actually making these?

I thought it was a joke...

junippor··on Data Science in Julia for Hackers
"For hackers" is a trick so you don't discourage people in HN. If you omit "for hackers", they'll say it has too much math and therefore no practical use. These are the same kind of people who think that the reason people use math is so they can feel smart about themselves, because practical people who want to do practical things don't need math - they have computers.
junippor··on 5 years of leetcode with no progress. I'm giving up
Very nice to see this here, as I recently signed-up to leetcode (and bought premium). I just went and check, and in the past 2 weeks I've solved 4.2% of the problems in leetcode, which means it would take me about a year to solve all problems, just like the post you linked.

Let me tell you something: hard work DEFINITELY plays a big role. I'm not saying "talent" isn't a factor too, of course. Other than sharing this, I'm not sure what kind of advice I could have. At least on paper you've done as much as you can.

If you allow me to guess something about your person with no basis at all: is it possible you just don't enjoy it? I know that for myself if I enjoy something I spent a lot of time thinking about it, even "down time" when your mind just wanders. I've always enjoyed little problems, and I can get lost in them for hours. If you do that a lot it's impossible not to get better at solving little problems. I think this possibly one overlooked aspect of "do something you enjoy". It's not _just_ that you'll get more enjoyment, it's also that you'll be better at it.

Good luck.

junippor··on Caricatures (2020)
The author seems to me surperficial enough as to believe he could get away with purposefully being ambigous and hoping that he can be flattering in the CEO's eyes while damning him with faint praise in the eyes of everyone else.

> The other example is actually our CEO – I think that there is a certain caricature required for public appearances & earnings calls, but he sometimes seems to speak genuinely at company all-hands meetings

Dear Engineer. If you're not pattern matching him, he's pattern matching you.

junippor··on Telegram is booming but needs advertisers and $700M soon
Why is this such a big issue? When I use Telegram in the past (and I did for years) every chat I had was encrypted. Enabling isn't that complicated.
junippor··on Telegram is booming but needs advertisers and $700M soon
Obviously you're missing that there's more factors to a person's choice than default encryption.

Not parent, but to me this one stood out.

junippor··on What's New in SQLite 3.35
> SQLite is called ‘lite’ for a reason. If you need functions, add them yourself.

Ok, lets say that SQLite developer believe this position has merit (they must've have, since they held it for 20 years, right?)

So what changed now which led to you implementing such functions?

Nothing changed, you just didn't _feel_ like doing it.

junippor··on UK to depart from GDPR
HN has always been bottom of the barrel. Bunch of people repeating memes to each other.
junippor··on Biggest void in space is 1B light years across (2007)
2007 was already 14 years ago. We don't even know if this is still there.
junippor··on Drop millions of allocations by using a linked list (2015)
In Julia if you have an estimate of the size (not necessarily a hard bound) you can `sizehint!` to reduce the number of allocations.

Can't read?

Julia is great, thank you for your work <3
junippor··on We created a fake language to root out resume liars
Russian gov say that Crimea voted to be part of Russia. What do you think of that?
junippor··on We created a fake language to root out resume liars
"Yazyk - Язык" is "language" is Russian. You know, because Russia took Crimea and eastern Ukraine is in civil war.

I learned Russian just so I could make politically edgy jokes, so this seemed like a good opportunity. Hopefully this will allow other ground dwellers to have a chuckle.

junippor··on China and Russia to build lunar space station
Unadjusted: $1.4Tr

Adjusted: $4Tr

I guess that whether or not it makes sense to adjust, in this case, depends on whether the expense will leave the country or not.

If you imagine that Russia's contribution to the project will be providing scientists and technology, maybe it makes sense to adjust.

"language" in Ukrainian is "yazyk".
junippor··on Bill Gates Says that Bitcoin is bad For the Planet
Moving the goal posts.

First you said "Just because Bill Gates is a billionaire, doesn't mean he knows what he's talking about"

Now that you've learned that most likely he DOES know what he's talking about, you changed your argument to "Other people think other things, so it's uninteresting" (What? WE're not talking about random people here.)

Lets just say it: you already arrived at the conclusion you want, now you're grasping for arguments to support it.

junippor··on Bill Gates Says that Bitcoin is bad For the Planet
No, just because he's a billionaire doesn't mean any of those things.

It's just that Bill Gates is legendary for the amounts he reads and his recall ability, and his contributions to many topics outside of just managing MS (state of the art algorithms, erradictinc malaria, nuclear energy etc). I thought everyone knew this, but apparently not. So you can see how funny it is when a random guy on HN says "just because he's a billionaire" :D

junippor··on Bill Gates Says that Bitcoin is bad For the Planet
Calling Bill Gates uninformed about anything is breathtakingly uninformed.
junippor··on Symbolics.jl: A Modern Computer Algebra System for a Modern Language
I'll make one (probably unpopular) comment.

On HN every time the subject of language wars or platform wars or browser wars comes up, the idea also comes up that "everything is about the number of users". The self-reinforcing cycle is that the language/platform/browser with the most users also has the most development time put into it, which then attracts more users, etc.

Fine, I don't deny that the phenomenon exists. But I think that it's often overlooked that it's not just about the number of users. It's also about the quality of the users. If we could quantify "an excellent developer", I wouldn't claim that Julia has more of those than Python. But I'm convinced that Julia has more "excellent developers who are also excellent at numerics" than Python. I think the idea that the productivity as function of "developer excellence percentile" is a power-law applies even more strongly in multi-domain expertise situations, like numerical computing. So forget about 100x coders. The contributions of some people like Chris et al are closer to 10_000x as significant as that of an ok contributor.

It's not just about the quantity, it's also about quality.

Ok fine. As far as footguns go, that's not the most subtle one.

junippor··on YouTube Suspends Rudy Giuliani Again for Election Fraud Claims
> When even a major Party Politician can no longer spew lies on (internet) television because the dominant corporation deems his lies to be unacceptable, Freedom of Speech is dead

Looking at it from Europe, this looks like the obvious consequence of decades of "free market fundamentalist" in America. If the free market magically solves all problems, eventually corporations will be making the rules. No surprises here.

You sound like those people who complain when new kingdoms of life are added :D

That's just how science works. We learn things.

Do you have any actual evidence of this?
