junippor··on Intriguing new result from the LHCb experiment at CERN
I'm pretty sure that Higgs had 2 independent experiments at >3 sigma which at the time added to more than 5 globally.
junippor··on Intriguing new result from the LHCb experiment at CERN
The world isn't binary where 5 is absolute truth and 4.99 is irrelevant.

3.1 is better than 1, so people think about it more than they think about 1, but less than they think about 5. This is how science _actually_ works.

junippor··on Elon Musk’s anti-union tweet from 2018 must be deleted: U.S. labor board
Isn't the relationship between unions and corporations NECESSARILY confrontational?

A corporation would like to pay its employees as little as possible. The employees would like the opposite. What am I missing? - genuine question.

I KNOW what the answer is :-P
junippor··on Why OO Sucks by Joe Armstrong (2000)
Your argument for why OO is good is that you prefer one syntax over the other? The examples you gave are just syntax and have nothing to do with OO.

You could imagine a language that isn't OO but where you could define the . operator to dispatch certain functions with the same syntax as OO.

You sound like you're trying to make a point. Make a point.
junippor··on Julia and the satellite Amazonia-1 (2020)
Yeah, that's often the case but I wanted to make a conservative claim.

Two personal examples where Julia turns out to be much much faster than Python without me having to do anything but the most naive implementation:

- order of 10 float arrays with order of 1_000_000 elements each. Broadcasting an element-wise function in Julia or just doing a for-loop in Julia is way way faster than a pandas operation like col1 * col2 + col3 etc.

- the first time I tried one of Julia's optimizers (I think Optim.jl) it took 1ms on my problem. Sci-kit took 200ms. That's crazy.

junippor··on Do you really want Linux phones
> What people really want, is a phone that is on their side

100% this.

Why is it so difficult to copy files to/from my phone?

Why is it so difficult to list all the files in a folder?

Why is it so difficult to get a list of what's running?

_Why is it so difficult to know that my phone is working for me_?

junippor··on Julia and the satellite Amazonia-1 (2020)
This post illustrates one of the reasons why I love Julia.

When talking to Python colleagues about Julia one response is "well, but I don't really care about performance _that_ much".

The thing about Julia is that you can code without caring about performance (and the performance will be Python-like). If later on it turns out that you DO care, you CAN optimize it. With Python you don't have that option, as in Python "optimizing" means using cython/numba over numpy arrays, and all the limitations inherent to that approach.

This is obviously good, and I'm not even sure what the trade-off is. What am I losing?

junippor··on Where are all the containers? The global shortage explained
Looking at your comment history, it seems that most of your comments lately are about the lockdown being bad.

You might have been radicalized...

junippor··on Berkson's Paradox
So I actually checked and... turns out you're right.

According to Wikipedia, "paradox" can either mean "logically self-contradictory statement" or a "statement that runs contrary to one's expectation". I always thought that it meant the former only.

These two concepts should really really have separate words.

junippor··on Berkson's Paradox
I like how you put paradox in quotes. I also annoys me when people call these things paradoxes. They're more properly called counter-intuitive phenomena. I wonder if there's a single-word name for that.
junippor··on Berkson's Paradox
> The latter appears when analyzing subgroups gives a different result than analyzing the pooled data.

> The former is about correlations that appear in samples which are not representative of the general population, due to the way that those samples are selected.

You just said the same thing twice. Think about it.

For one you used terms like "subgroups" and "pooled data" and for the other "samples" and "general population". Those are the same things.

Then you used "[the effect] appears in" and in the other "correlations". Well, Simpsons paradox can also manifest itself in correlations. So you just said the same thing twice.

Yes.... exactly....

Thank you. Does anyone understand the difference between this and Simpson's paradox?

Not tactful, but he has a point. Some people are just fundamentalists (with bad fundamentals).
junippor··on Venus could have been habitable for billions of years (2019)
It's none :D

If you knew anything about chemistry past checking wikipedia, you'd just call it none.

junippor··on Venus could have been habitable for billions of years (2019)
I'm just gonna leave this here.

https://en.wikipedia.org/wiki/Venus_atmosphere

Hydrogen chloride 0.1–0.6 ppm

Hydrogen fluoride 0.001–0.005 ppm

junippor··on Venus could have been habitable for billions of years (2019)
Except, there's no hydrogen in Venus.

> analyzed companies/special situations, and created financial models in order to invest my savings

You say you "analyzed" and "created financial models". But did you actually put money into it? And if so, did you make money?

junippor··on Venus could have been habitable for billions of years (2019)
That's been thoroughly debunked.
junippor··on Venus could have been habitable for billions of years (2019)
Venus is almost guaranteed to be currently uninhabited because that planet has almost no hydrogen in it.

Almost all "complex chemistry" that we know of involves hydrogen.

So to those people who say "but but but that's just life as we know it". No, it's also chemistry as we know it.

Literally on the front page.

junippor··on EU vaccine rollout severely lags behind
CTRL-F bureaucracy

Cue HN complaining how much "bureaucracy" and how much "red tape" the EU has, and smth smth socialism.

junippor··on Richard Stallman: “Unjust computing clamps down” – video from LibrePlanet 2021
Does anyone know how these things work? Why did he resign the first time? Was he asked to and he accepted for no reason and now regrets it? Or was there a mechanism used to force him?
junippor··on UK 'heading towards digital skills shortage disaster'
The parent post was downvoted by the HN hivemind who loves opining about things it knows nothing about.

I live in the UK and while parent is obviously hyperbolic, it has some truth in it. Where I work, people with engineer in their job title are _literally_ the ones that come around when your computer breaks and they turn it off and on again.

Come to think about it, parent isn't even that hyperbolic...

junippor··on Working at Goldman Sachs Suuuucks, Leaked Internal Survey Shows
For the question "why would anyone want to work at GS as opposed to their clients", it's not a matter of the number of corporations, it's about the number of good roles.

A very large, say property developer, might hire GS for its fundraising needs, but a GS grad wouldn't want to work laying bricks. He might want to work as CFO or someone very close to the CFO, but those roles are much harder to get than working as grad for GS.

So it's not just about what the grad wants, it's also about what he can get.

This shouldn't be controversial. Anyone who's been in the industry knows that people move "up" from IB to their clients. Of course everyone wants that, but again such roles are harder to get than IB.

junippor··on Tesla orders its first 8k-ton Cybertruck casting machine
Can you explain to me why someone would want to buy such an ugly car? Is it just elon fanboyism, or is there more to it?

Probably there's more to it and I'm out of the loop :D

Yes, but... those jobs are even harder to get into than investment banking :-)
