The most obvious thing is that I post things out when I want people to see it, and LW/Twitter is mostly about how serious I want to be.
I don’t really. Idea get revisited when I stumble on it again, but I rarely try to plan and focus on some ideas without external stimulation.
The rules are not completely consistent over time though, also it is just not articulatable in 1 minute of effort lol. I’m sure I can explain 80% of the internal rule with effort
Obsidian/LW Shortforms/Twitter for slightly different types of ideas, can’t articulate the difference though
Don’t really want to touch the packages, but just setting the EVALS_THREADS environmental variable worked
Tried running but I got
[eval.py:233] Running in threaded mode with 10 threads!which makes it unplayable for me (because it is trying to make me to 10 tests alternating
Wealth $10k, risk 50% on $9999 loss, recommends insure for $9900 premium.
The math is correct if you’re trying to optimize log(Wealth). log(10000)=4 and log(1)=0 so the mean is log(100)=2. This model assumes going bankrupt is infinitely bad, which is not accurate of an assumption, but it is not a bug.
You can still nominate posts until Dec 14th?
Thought about community summaries a very little bit too, with the current LW UI, I envision that the most likely way to achieve this is to
Write a distillation comment instead of post
Quote the first sentence of the sequences post so that it could show up on the side at the top
Wait for the LW team to make this setting persistent so people can choose Show All
There is also the issue of things only being partially orderable.
When I was recently celebrating something, I was asked to share my favorite memory. I realized I didn’t have one. Then (since I have been studying Naive Set Theory a LOT), I got tetris-effected and as soon as I heard the words “I don’t have a favorite” come out of my mouth, I realized that favorite memories (and in fact favorite lots of other things) are partially ordered sets. Some elements are strictly better than others but not all elements are comparable (in other words, the set of all memories ordered by favorite does not have a single maximal element). This gives me a nice framing to think about favorites in the future and shows that I’m generalizing what I’m learning by studying math which is also nice!
It is hard to see, changed to n.
In my life I have never seen a good one-paragraph explanation of backpropagation so I wrote one.
The most natural algorithms for calculating derivatives are done by going through the expression syntax tree[1]. There are two ends in the tree; starting the algorithm from the two ends corresponds to two good derivative algorithms, which are called forward propagation (starting from input variables) and backward propagation respectively. In both algorithms, calculating the derivative of one output variable with respect to one input variable actually creates a lot of intermediate artifacts. In the case of forward propagation, these artifacts means you get for ~free, and in backward propagation you get for ~free. Backpropagation is used in machine learning because usually there is only one output variable (the loss, a number representing difference between model prediction and reality) but a lot of input variables (parameters; in the scale of millions to billions).
This blogpost has the clearest explanation. Credits for the image too.

or maybe a directed acyclic graph for multivariable vector-valued functions like f(x,y)=(2x+y, y-x)

Donated $25 for all the things I have learned here.
Strongly agreed. Content creators seem to get around this by creating multiple accounts for different purposes, but this is difficult to maintain for most people.
I rarely see them show awareness of the possibility that selection bias has created the effect they’re describing.
In my experience with people I encounter, this is not true ;)
Joe Rogero: Buying something more valuable with something less valuable should never feel like a terrible deal. If it does, something is wrong.
clone of saturn: It’s completely normal to feel terrible about being forced to choose only one of two things you value very highly.
Yes!
By default I expect the author to have a pretty strong stance on the main idea of a post, also the content are usually already refined and complete, so the barrier of entry to having a comment that is valuable is higher.
Bob can choose whether to to hide this waste (at a cost of the utility loss by having $300 and worse listening experience, but a “benefit” of misleading Tim about his misplaced altruism)
True in my example. I acknowledge that my example is wrong and should have been more explicit about having an alternative. Quoting myself from the comment to Vladimir_Nesov:
Anyways, the unwritten thing is that Bob care about having a quality headphone and a good pair of shoes equally. So given that he already has an alright headphone, he would get more utility by buying a good pairs of shoes instead. It is essentially a choice between (a) getting a $300 headphone and (b) getting a $100 headphone and a $300 pair of shoes.
If the bad translation is good enough that the incremental value of a good translation doesn’t justify doing it, then that is your answer.
I do accept this as the rational answer, doesn’t mean it is not irritating. If A (skillful translator) cares about having a good translation of X slightly more than Y, and B (poor translator) cares about Y much more than X. If B can act first, he can work on X and “force” A (via expected utility) to work on Y. This is a failure of mine to not talk about difference in preference in my examples and expect people to extrapolate and infer it out.
Again, seems like we are in agreement lol. I agree with what you said and I meant that, but tried to compress it into one sentence and failed to communicate.
This is pretty cool. A small complaint about the post itself is that it does not explain what Squiggle is so I had to look around in your website to understand why this Squiggle language that I have never heard of is used.
