Thanks for creating Gensim!
Sinidir··on What Is Hammock Driven Development?
Yeah. More like hike driven development.
Sinidir··on How JavaScript engines achieve great performance
Javascript is singlethreaded. No locks and therefore no lockfree datastructures necessary. Even webworkers are only communicated with via copying messages.
Sinidir··on The Reactive Monolith – How to Move from CRUD to Event Sourcing
It seems the benefits of eventsourcing can be had from using an immutable database. Auditing, Backing up state while the db is running, previous states and diffs.
Sinidir··on How I debate
>If p=0.05 is sufficient confidence to publish, one in twenty published findings will be wrong

This is a wrong understanding of p values. Imagine an urn with only fair 50/50 coins and taking out coins to test them. If you reject the coin being fair at 0.05<p then you will on average have 1/20 statistically significant results. All of your statistically significant results will be wrong.

Now imagine an urn that only has biased coins. Every time you reject the null hypothesis you are correct.

How many statistically significant results are actually true depend on the metaphorical urn that people draw hypothesis out of. If someone is very good at picking likely hypothesis to pan out their statistically significant results are more likely to be true.

Also if a field of study has many bad paths you could go down on then you would expect more statistically significant results to be actually wrong.

Sinidir··on New Ways to Be Told That Your Python Code Is Bad
Brilliant.
Sinidir··on Banach-Tarski and the Paradox of Infinite Cloning
Can someone correct me if im wrong?

What i see here is a splitting of the set of points in the sphere? However the set of points in the sphere is not really the sphere. A point has no volume so no matter how many you add together you don't get something with a volume. This seems more akin to splitting the natural numbers into odd and even numbers which are all equally large.

The language that i see in this article and elsewhere however is suggesting that we actually duplicated the sphere (doubled the volume).

This seems incorrect.

Sinidir··on Show HN: I made an interactive anti-procrastination video course
Bookmarked ...
Sinidir··on Principal Component Analysis Explained Visually
Question: is there any difference between the highest variance dimension pca finds and a line that linear regression would find?
Sinidir··on Show HN: I'm working on a open-source, self-hosted alternative to Disqus
Smart strategy. Maybe someone could even make a project out of that called RedditAlternativeTo.
Sinidir··on Docker without Docker
How many landing pages have i scrolled down 2 pages and still barely a clue what the service is supposed to do.
Sinidir··on EU experts to say nuclear power qualifies for green investment label: document
I had the same impression. Quite sad that this anti renewable propaganda bit taints the entire post.
Sinidir··on Researchers looking for mRNA were ridiculed by colleagues
Perfectly put.
Sinidir··on How to be more productive without forcing yourself
How do you manage a job with this?
Sinidir··on Veloren – Open-source MMORPG written in Rust
no
Sinidir··on Ask HN: What is your “I don't care if this succeeds” project?
Wow. I have never seen someone project this amount of anger onto a random person on the internet. Maybe take a day off before your head explodes.
Sinidir··on A 25-Year-Old Bet Comes Due: Has Tech Destroyed Society?
Great minds think alike :P
Sinidir··on How hard should I push myself?
Yeah i have similar problems. I seem to be very momentum based, as in it costs time to get into a state where i can put in effective work (also takes time to get back into a relaxed state). With that being the case i construct scenarios in my head where i put lots of tasks together so i can do them when i got the ball rolling and there is a synergistic effect of not duplicating effort. Plus there is a strict divide between stress and relaxing.

But through that all these tasks form a big daunting mountain of stress and effort together and then i keep putting them off and procrastinate.

Sinidir··on What Is Life? (2019)
So you're making an assertion about something that the human mind cannot comprehend. Nice contradiction + random dig at people to make yourself feel superior.
Sinidir··on Ask HN: How to Take Good Notes?
This has been sooooooooo true for me in unversity.
Sinidir··on ML From Scratch, Part 1: Linear Regression
Understood everything up until this:

        ∇ΘJ=∇Θ(y−XΘ)T(y−XΘ)
expanded into

        ∇ΘJ=∇ΘyTy−(XΘ)Ty−yTXΘ+ΘT(XTX)Θ

Can someone explain why ∇Θ is only applied to the first term? Also i have never seen gradient notation used like that before.
Sinidir··on The wisdom of never leaving your hotel room
Not reading, but he just did a joe rogan podcast. https://www.youtube.com/watch?v=udlMSe5-zP8
Sinidir··on Introduction to Decentralisation
I have seen this phenomenon so often in explanations/tutorials of different things. People seem to not have a concrete target audience in mind. They simply write of cuff.
Sinidir··on Next-Paradigm Programming Languages: What Will They Look Like?
An overview of a problem that I run into is the need to pair some input, validate that input, query the system based on the input, expose the intermediate stages for inspection and modification by arbitrary consumers, conditionally modify the underlying system in some way, and provide well defined semantics around the outcome while handling failure recovery, distributing the processing into multiple, cancelable stages, and sharing the system context and other forms of memory with concurrent operations.

This sounds like a dream for data analysis.

Sinidir··on The End of Scientific Linux
Thats pretty cool.
Sinidir··on A cure for cancer: how to kill a killer
Godspeed
Sinidir··on How the octopus got its smarts
That's adorable.
Sinidir··on How the Go runtime implements maps efficiently without generics
I really don't understand why go doesn't have generics. Shouldn't it be even easier because go has no inheritance? So the problem of covariance and contravariance goes away.

Seems really strange.
