You missed my point (and the author’s it appears).

You’re claiming to understand learning. People do phds in learning from multiple domains (psych, neuro, ux, etc). You already know it all?

The rabbit hole is deep. Coming in here and saying yeah yeah we all get it already is a sign that you don’t.

> Learning isn't coming up with new analogies for concepts you already completely understand over and over again.

You completely understand learning? :)

Re:Fractal Learning on Sunday October 11, 2020 @09:13AM (#24745528)
Oh my goodness, you literally wrote the ideas I was thinking about from a learning perspective.

I wrote about very similar things from a teaching perspective here: https://lelon.io/blog/how-to-teach-math

In fact, I've thought a lot about how to generalize these techniques to a data structure (i.e. knowledge graph) so that anyone can zoom in or out to whatever level of abstraction they please:

Would love to chat sometime!

which meds are you taking?
> Which companies are you referring to?

None specifically - I'm just interested in pivot points where companies decided to switch from technology x to technology z, and what made them do it.

> When did that happen? If everyone did "leave PHP", what will happen to all those websites:

Sorry, bad phrasing. I meant, "When did people stop deciding to greenlight new projects using PHP?"

Thanks!

Would you be interested in such a chart? or perhaps a tweaked version?

Ask HN: Resource for learning the history of software dev best practices?

I'm a young developer and I feel like I have such little context for where and why we are today.A few examples:- what tradeoffs did companies examine before concluding to move to microservices from monoliths? Which companies decided not to? Why?- When Angular.js first came out, what made companies adopt it? What were they using before?- Why did everyone leave PHP?- What made Postgres become...

This is really cool!! I hope this becomes popular. Imagine having all theorems etc indexed like this!

This doesn't make much sense to me. How can there be a new scientific method?

Shouldn't these somehow boil down to the same thing: hypothesis, experiment, evidence against the null?

I feel like my company is a little too liberal with it. I suspect it might be a sign of some sort of fragmentation, but I'm not sure what kind (e.g. org chart, proj mgmt, no established point of contact for certain things).
Re:Ask HN: What made you abandon learning to draw? on Wednesday July 15, 2020 @10:59PM (#23855260)
For me, personally:

> what motivated you to learn to draw

Half of me wanted to impress my friends. The other half of me wanted to make stories come to life.

> what you were interested in drawing

Mostly animated characters. Faces. Portraits.

> biggest roadblock/weakness

PROPORTIONS. I hated how I'd draw something and it would always look "slightly off" but I couldn't really put my finger on exactly why

> how many times you've tried to learn

Probably about 3 times..

Re:Ask HN: Did you take any fresh MOOCs as of 2020? on Friday July 03, 2020 @11:14AM (#23724710)
No offense, but are you joking? This is an extremely cynical take.

You don't see any benefit to having one mega amazing course?

You think there's no way to overcome the limitation you mentioned (bad information) at all? How about a peer review process?

FWIW I thought they were both pretty spot on. In fact, you mentioned this about DNS:

"As I read articles and tried stuff out (and broke my server config more than once) I started to grasp the system, to get glimpses into how it all worked, until eventually it “clicked” and I felt comfortable working with it."

Have you written about your mental models for DNS? Color me interested!

Ask HN: Most interesting trade-off phenomenons in your field?

As I talk to different folks from different domains, it's always interesting to me to learn what they're optimizing for and what the variables are.Usually there's a sweet spot between two extremes.Examples:- Bias-Variance trade off from statistics and machine learning- Freedom vs Security from philosophy- Explore vs Exploit from computer scienceI'd love to hear some other examples from e.g....

Ask HN: Tools or mental model for answering subjective questions quantitatively?

Hello HN!I'm interested in tricks, tools, or mental models to help answer subjective questions with accuracy and precision (and eliminate biases).For example, how do you turn the following questions into insightful, actionable data?- How much does this hurt?- How much do you like this product?- What are you feeling right now?Backstory:I'm 28 and I developed tinnitus out of nowhere a few months...

That's my problem as well.

The docs told me I have ADHD. Maybe you do, too?

Re:Do whatever you can't stop thinking about on Sunday March 08, 2020 @04:43PM (#22520474)
Not who you replied to, but you described me to a T.

Problem is - I have no idea what to do about it.

It's so hard to do anything fun in my free time because the moment I think about doing / starting something, goal oriented t thoughts follow, which means stress follows.

I wish I could just go into "kick the can" mode whenever I wanted and turn off the part of my brain that wants to see results, progress, and checkmarks.

A lot of what you're talking about is discussed in the following link, so I figured I'd mention it:

I'm also very interested in tech education and edtech.
