Rainymood··on Almost every infrastructure decision I endorse or regret
As a machine learning platform engineer these sound like technology choices as opposed to infrastructure decisions. I would love to read this post but really with the infrastructure trade-offs that were made. But thanks for the post.

Side node: There is a small typo repeated twice "Kuberentes"

Rainymood··on Business advice plagued by survivor bias (2009)
A shower thought I had recently is that we should start referring to "Business cases" as "Survival cases" and "Business books" as "Survival books" and that makes the inherent bias so much clearer.
Rainymood··on Why new hires often get paid more than existing employees
So, effectively, there was... no rule.
Rainymood··on List one task, do it, cross it out
I have one notebook that I carry around where I list tasks just in order to cross them out. There is something so viscerally satisfying in crossing out a task that just provides so much momentum to whatever I'm doing. There's just something beautiful about making the implicit explicit and then striking it through.
Rainymood··on Lessons learned building an ML trading system that turned $5k into $200k (2019)
Very interesting post and I read it in full. The article is definitely interesting but I found it a shame that the author didn't talk more about his system that brought him from 5k to 200k as the title implies :)
Rainymood··on Ask HN: How Is Plaid Legal?
I asked this question 5 years ago in an AMA the CEO did once here, but they plainly ignored me and are a unicorn 5 years later. The trick here is to move so fast that the law has trouble keeping up (same with Uber/AirBNB).
Rainymood··on Freezing Requirements with Pip-Tools
Did you ever try poetry[1]?

It is a great tool that I use in all my projects. It effectively solves dependency management for me in a very easy to use way.

Dependency management using requirements.txt used to give me such a headache, now I just have a pyproject.toml that I know works.

    [tool.poetry.dependencies]
    python = ">=3.8,<3.9"
    pandas = "^1.4.3"
This basically means: Use the version of python between 3.8 and 3.9 and use any version higher than 1.4.3 for pandas.

What I like about poetry is that it makes sure that the whole dependency graph of the packages that you add is correct. If it can not solve the graph, then it fails fast and it fails hard, which is a good thing.

This is probably a very bad explainer of what poetry does, but be sure to check it out! :)

Rainymood··on Decentral Bank fixes bug that let one user mint 10T USN for just $10
Very decentralized, until we don't like it anymore, then very centralized.
Rainymood··on A drug that cures alcoholism may be the next anti-anxiety medication
I'm half asian and I get the "Asian flush" [0] which for all intents and purposes induces the same effect as this drug (DSF)

>Individuals who experience the alcohol flushing reaction may be less prone to alcoholism. Disulfiram, a drug sometimes given as treatment for alcoholism, works by inhibiting acetaldehyde dehydrogenase, causing a five to tenfold increase in the concentration of acetaldehyde in the body. The resulting irritating flushing reaction tends to discourage affected individuals from drinking.[9][10]

I literally have a negative feedback loop from drinking alcohol, it makes me feel really bad, my skin flushes, I feel my heartbeat in my chest/neck/head, and I literally feel miserable.

Honestly, it kind of sucks, because when you can't drink you notice how much socialising is based around alcohol. I've found ways to cope with this and am on good terms with myself now but it really took me a long time. Especially to get around the social/peer pressure of having to drink.

On the bright side, I'll likely never become an alcoholic.

Rainymood··on Four Secret Novels by Brandon Sanderson
Very happy that Brandon Sanderson is looking more and more healthy as time goes on :) love his writing
Rainymood··on 'Dutch reach' rule change to Highway Code welcomed
As a Dutch person, I was never taught this, I can see it is good practice but we just don't do it. All we do is check over our shoulders before we open the door because we know there can be a cyclist. Why? Because we are all cyclists so we know it can happen...
Rainymood··on The Power of Defaults
I liked the post a lot, but I am furiously sceptical about this claim:

>This is why Apple Maps has higher market share than Google Maps

Do you have any (recent) source for this or is this just a wild guess? I literally know no one that prefers Apple Maps over Google Maps.

Rainymood··on An Honest Comparison of VS Code vs. JetBrains – 5 Points
I use PyCharm JetBrains for most of my development work, the testing/debugging setup just works too good out of the box.

I just wish PyCharm 100% copied the way search/find works in VS Code. PyCharm search and find is so awkward, and VS Code's is so good.

Rainymood··on Health care is turning into a consumer product
>In NL, you pay ~€110/month annually, with a max out-of-pocket cost of €385 per year. So, maximum €1600 cost annually.

My provider, CZ, charges ~€150/month with max-out-of-pocket ~€385. If you get the full ~€850 out of pocket then your monthly payment drops to ~€110/month.

Rainymood··on Ask HN: Those making $500/month on side projects in 2021 – Show and tell
I love this so much. No frills, just software solving (boring) problems in a scalable way. All the best :)
Rainymood··on Step Away from Stack Overflow
This solution is really bad, read it in as a dataframe and use a groupby...
Rainymood··on How a Kalman filter works, in pictures
I remember this blog post from ~3 years ago when I had to write my MPhil thesis :) thanks for this, it really helped me understand it!
Rainymood··on Googling for Software Development: What Developers Search for and What They Find
Yesterday, I wrote a short blog post titled "Don't mistake the internet's intelligence for your own" [0] which is very closely related to this blog post here. I wrote it it to shine some light on the fact that knowledge on the internet (Google, SO) is not ~your~ knowledge. This fact often gets painfully exposed during interviews. Funny timing.

Rainymood··on How to learn mathematics: the asterisk method
This is the so-called "Illusion of competence/learning" [1] and I have become fascinated with this topic (and learning in general). The only way out of this trap is to self-test.

Rainymood··on Some reasons to work on productivity and velocity
Is there any version of Dan Luu's website with just a hint of css? Plain HTML is unreadable imho, content is usually great but I struggle to get through it because it's so damn hard on the eyes.
Rainymood··on You're Not a 10x Programmer
>If you feel like a better than average programmer, there’s a 50% chance you’re correct.

This is not correct right? The word average should be replaced by the word median. Then this sentence is correct.

More on topic. I strive to be a 10x engineer by multiplying the output of my 1x teammates (including myself) by a factor 2... if I manage to make my team of 5 all twice as productive, boom 10x!

Rainymood··on Ask HN: How do I get fit and healthy as a software engineer?
I do Brazilian Jiu Jitsu (BJJ) to stay fit. It's a really fun and intellectually stimulating (yes, really) grappling martial art. I do it three times a week and am always completely exhausted, sore, and drenched in sweat after every session!

Any other BJJ nerds here?

Rainymood··on To Don't – The reverse to-do list
What you describe is the basis of cognitive behavioral therapy (CBT). I use it personally and has helped me greatly https://en.wikipedia.org/wiki/Cognitive_behavioral_therapy
Rainymood··on The Applecare Hustle
In theory, theory and practice are the same.

If you are interested in this and want to further your studies in this field try looking up this thing called "Prospect theory", it's like game theory+.

Rainymood··on Lessons Learned from 5 years using Pivotal Tracker
>The Unit of Work is not the Unit of Value

Resonated with me a lot. I've been working on a high-value ticket for 2 weeks now and close to cracking it. But it feels bad because I've "only" worked on 1 ticket while my co-workers have been burning through smaller tickets with 1-2 line code changes... makes me feel bad and anxious to be honest that I'm not doing enough work

Rainymood··on How to Remember What You Read
I'm also using flashcards and the Anki app to memorise syntax. I got sick of looking up the difference between list.append and list.extend and all kinds of small things. Hope it helps...
Rainymood··on Launch HN: Slip (YC S21) – Build and sell interactive programming courses
Been following you on twitter since vim.so! Godspeed to you sir!
Rainymood··on Show HN: I built an app to create repeatable checklists to help with ADHD
What is the reason it requires iOS 14.1 or later? I run an old version for iOS and would love this. I make repeatable checklists for everything and I feel like this could really help me out.
Rainymood··on JavaScript for Data Science
Really cool but no one needs this... as a data scientist learning javascript, teach me how to run data science models using javascript! That's where the real gold is... I'm even thinking of writing articles about this myself... JS is great for making things more tangible and interactive
Rainymood··on Fed up with the Mac, I spent six months with a Linux laptop
Wait what? You can make small changes in preview?!
