Braindump thread on 🇮🇳/math/acc after I spoke with many experts on this:

At International Math Olympiad, Indian students do okay on number theory and algebra but struggle with geometry which "needs serious creativity that is tough to learn in regular school. Problem #6 in IMO is where India has struggled the most across the years"

(1/N) A big factor for India's math olympiad performance has been that many students are not even attempting this exam, simply due to lack of awareness.

If you're in school and enjoy mathematical problem-solving, consider taking IOQM, even if just for fun. (2/N)

I'm going through @AndrewYNg's prompt-engineering course today. Sharing key slides and my notes in this thread:

1/N: Base LLM predicts next word. Instruction-tuned LLM (like ChatGPT Web UI) follows instructions. Most practical applications use the latter.

2/N: First principle for prompting an LLM is to write clear and specific instructions (even if the prompt gets longer)

A few tactics are recommended for this.

(a) Use delimiters (eg: ```, """, < >, <tag> </tag>, :) to clearly indicate distinct parts of the input

It's also amazing that all media coverage of Signal refers to it as a "non-profit" or "open-source" - both of which are now false as they built MobileCoin (85% pre-mined) integration in secret.

And the UX is trash - the one thing which @moxie justified all the compromises for.

Blockchain is best understood in geopolitical frame. Internet is now a sovereign country, now able to give its residents property rights using blockchain and people are immigrating to it. Doesn't have an army yet. Nation states need to decide if they want to be allies or enemies. People have been moving to Internet with their attention and consumption and productive capacity for a while but they could never build property rights on internet. Now they can.

It's a loose analogy. Food, sex, kids are still in the real world.

Documenting the death of AMP pages in this thread.

@TwitterEng will no longer be sending mobile users to AMP pages. AMP to be phased out completely by Q4-2021: searchengineland.com/twitter-rolls-… Next: @MacRumors is dropping AMP altogether:

I've been going through Math syllabus (till grade 10) so many topics seem out of place in today's age. These topics have very little pedagogical value and almost none usefulness. Here are a few:

(a) Solving system of equations using cross multiplication This is just a shortcut for solving by substitution /elimination and doesn't even generalize well for > 2 variables or linear algebra. Why should we optimize for speed of solving by hand in this age?

(2) Statistical novelties: Mode, Ogives, fancy formulas for grouped data:

Education: Where family, community & government determine what's best for the child. Sure, all 3 love the children, but at the same time, they also want to use them as "human resource" to some extent.

Nothing wrong with it, but important to understand this. The student, by definition being ignorant, is left out. We just hope that somehow, with these 3 competing interests, the individual interest will be preserved.

There's a troubling thought: When thinking about the aims of education, we use ideals like these.
