Rainymood··on How tracking pixels work
>Safari and Firefox both block many third-party cookies by default (which is why I had to change Firefox’s privacy settings to get this experiment to work), and as of today Chrome doesn’t (presumably because Chrome is owned by an ad company).

Wow. I am very strongly considering switching to Firefox now, just from this paragraph.

Rainymood··on Ask HN: Best Way to Measure Progress?
How?
Rainymood··on Ask HN: My company wants my side project. What can I do?
Step 1. Realize that advice on HN is often wrong and very one-sided (i.e. they were dead wrong about Dropbox)

Step 2. Figure out what you want, and why, and get it in writing. Figure out what your company wants, and why, and get it in writing. Then open a dialogue and its time to start talking and negotiating!

Rainymood··on Ask HN: How to improve code quality while maintaining decent velocity?
>Also a confused guy stopping meetings is the worst - taking time out of the entire team who now has to listen to stuff they already understand explained again. Pull someone aside afterwards for clarification.

"Also a student stopping lectures is the worst - taking time out of the entire classroom who now has to listen to stuff they already understand explained again. Pull someone aside afterwards for clarification."

You are part of the reason why people are scared to speak up and ask "stupid" questions, and I feel like that ends up being a net negative.

>I was trying to make a profit is pretty constraining. You have to satisfy customers or you go out of business. [1]

Hehe this one was pretty good.

Rainymood··on Urbit
Is this some kind of over-the-top joke that I'm not in on? I've browsed and read but honestly still can't understand what Urbit is. When I saw the picture of the stone with the thing on top I thought I was finally "in" on the joke, but they seem to continue on.
Rainymood··on To motivate people, talk about the context of the work to be done
I would argue: leaders lead and managers manage.
Rainymood··on To motivate people, talk about the context of the work to be done
>It's becoming a huge peeve of mine when people seem to have forgotten what thread they're in and take a statement out of all reasonable context or nitpick about things that do not materially degrade the point (quotes are a little fussy that way, who knows how people will interpret them).

Welcome to HN

Rainymood··on What Do You Think about This Seamless “Registering/Login” User Experience?
My prediction: People on HN will hate it, the general public loves it.
Rainymood··on K-means clustering using sklearn and Python
>I should start calling myself a ML expert? I'm 32 year old and most of these "ML algorithms" are called statistics for me. Maybe I'm missing something, where is the LEARNING on k-means? Numerical solutions seems to be on rise now.

Yes, you can. I have studied statistics and I cringe at the watering down of what "machine learning" and "AI" has become; simple statistics.

>Nice write for someone starting, more details about details of algorithm steps would greatly attract more readers.

I disagree, making it even simpler would attract more readers. You see the same with Youtube tutorials that have 22 parts. The first part has 200.000 views, the second 150.000 and the 20th part only has 400 views or so.

Rainymood··on The Little Handbook of Statistical Practice (2012)
This is nothing new. People have always whined about the overgeneralised conclusions from studies with low N counts and the inability to reproduce them.
Rainymood··on Microsoft Wins Pentagon’s $10B Contract
Only after their employees revolted. Never forget this. Only after the employees spoke up.
Rainymood··on McKinsey: Half the World’s Banks Too Weak to Survive Downturn
I'm thinking of applying to McKinsey as a data scientist, could we have a chat sometime?
Rainymood··on Rejected from YC (Again)
I remember reading the article when it got first published in June 2019, this is the same article but with an update at the end. YC W20 batch just got all their letters.

Good luck, I hope you guys succeed and keep grinding!

Rainymood··on Ask HN: What are your biggest regrets?
I'm in my early 20s now :) Do you have any concrete tips/things you wished you did differently?
Rainymood··on Ask HN: Do you work with a “hands-on” VP/CTO?
>No roadmap to be seen. No high-level goal. No security policy in place. No offboarding process. No onboarding policy. No central auth server. A few different job schedulers. Few different container orchestration solutions. etc

Have you asked about these things? Maybe they are there, just not visible to you. A 500-employee company is pretty big already.

Rainymood··on Blizzard bans player from Hearthstone following on-stream Hong Kong protest
That's like, totally your opinion. Blizzard has a huge base in China that is largely invisible to us. As a large (gaming) company you want to stay as neutral as possible, or at least that's what I imagine what large PR firms would consult Blizzard to do.
Rainymood··on Blizzard bans player from Hearthstone following on-stream Hong Kong protest
While I agree with the sentiment that is being expressed here (i.e. it's "wrong"). I can't help but think about the fact that he ... simply broke the rules. There is a clear clause in the ToS that states basically "You are working for us. If you say anything that can damage our reputation, we can cease working with you." Which, to me, makes a whole lot of sense to have as a clause.
Rainymood··on Foundations of Data Science [pdf]
Communication skills, business insights, politics ... those for starters ...
Rainymood··on Show HN: Able – an alternative to Medium
>People are increasingly skeptical of "platforms" and proprietary licensing.

And with people you mean ... ? The general public (i.e. "people") don't really care much about their privacy.

Rainymood··on Why some software developers hate Agile
>Committing to dates and then being accountable for the results

I found a very good way of getting around this. If you need to estimate a task, estimate it honestly in your head (say 2-3 days) and then double the amount.

It almost feels like cheating but with this method I have consistently delivered timely on my responsibilities. This method works because we usually plan way too optimistically.

Rainymood··on Ask HN: Did anyone leave Software Engineering as your profession? If yes, why?
No need for extreme measures. Why not do some gardening in the weekend? Some manual labour?
Rainymood··on Measuring actual learning versus feeling of learning
This stuff is super important and it is good that it is being researched seriously. The money shot is right here in the abstract

>We find that students in the active classroom learn more, but they feel like they learn less.

>We show that this negative correlation is caused in part by the increased cognitive effort required during active learning.

In other word, "real" learning is hard, it takes work, it's not fun. The problem is that "the algorithms" (whatever recommendation ML algorithm YouTube has) works so damned well we are sucked into this endless shallow junkfood dopamine loop of videos that give us just the right amount of dopamine to click on the next one.

If you're struggling, you're learning.

Rainymood··on The Myth of Commoditized Excellence
Indeed, I think "toolness" should be replaced by "impact" or "effectiveness".

Code, for example, can be played with but can also deliver significant impact to a large group of people.

A toy car, as another example, can be played with but delivers value to only one person at once (well, depending on how you use it).

Rainymood··on The Myth of Commoditized Excellence
The (real, complex) plane is equivalent to (toyness, toolness) although it is an interesting idea indeed to express it in polar coordinates hah
Rainymood··on The Myth of Commoditized Excellence
Perhaps they are two completely different dimensions, imagine the x-axis being the "toolness" of something and the y-axis being the "toyness" of something.

A nuclear reactor is something that would have a very low "toyness" score, i.e. you wouldn't "play" with it.

A plastic toy car would have a very high "toyness" score, as it is literally designed to play with (by kids).

I kind of fear my analogy of two different dimensions breaks down here because I'm left wondering what things would have a low "toolness" score ...

Rainymood··on The Myth of Commoditized Excellence
What is a tool and what is a toy? Or do they overlap?

I would classify a motorcycle (I have one too) as a tool for both transport (get me from A to B) and fun (riding it is fun).

That being said, holy mother of god it is stressful when there are other cars on the road, people are freaking scary in cars.

Rainymood··on Gradient Descent: The Ultimate Optimizer
I couldn't find the code anywhere on the web (nicely formatted, easy to use) so I tried to make the code more easily accessible here [1]

Rainymood··on Why It’s Hard for Startups to Create Wealth in Europe
>European consumers and lawmakers here have long decried outsize paydays as unfair and vulgar. A few years ago the Dutch capped bonuses for bankers, money managers, and other financial professionals at 20% of their base salaries.

Well, yeah, because they gamble with other people's money. Prop traders still make a big buck here in the Netherlands. (Dutch here)

Rainymood··on Pizza robot makes 300 pizzas per hour
What have the workers done to "earn" this? They literally signed an agreement to work X hours for Y amount of dollars. They said yes to that. If they wanted a piece of the equity -- the profits, they should have negotiated for that in their contract.
