ruang··on Tell HN: My Microstartups make $500/day while I'm sleeping
Is it getting harder these days to come up with new similar ideas, maybe due to legal pressures?
ruang··on Ask HN: Been writing code for 40 years and can't get hired
Excellent list, thank you!
ruang··on Stanford CS Curriculum 2021
Can the Stanford compiler course be self-taught given the online material? What's missing?

I've seen it available on Coursera. And a lot of the current material is available online. But I tried the Coursera one awhile ago and got stuck.

I'm finishing a CS degree but there's no dedicated compiler course here.

ruang··on How to increase your luck surface area (2010)
I like Peter Thiel's quote: A-B testing only works if you have a billion years (from Darwin)
ruang··on Distributed Systems Reading List
Is linear algebra useful to learn for distributed systems?

I'm taking graph theory next semester and wondering what else might be useful. I took a distributed systems course already and we used no math at all.

ruang··on Notes for courses taken at Harvard (2015-2019)
These are great. I wonder why he didn't just handwrite the notes. These are much better, but they seem like they would take a long time unless you can type latex quickly.
ruang··on Why is Snowflake so Valuable?
What kind of math is involved in building a faster database? Genuinely curious. I would guess maybe linear algebra, indirectly.
ruang··on How Not to Learn Cryptography (2014)
Thanks, I'm doing a Masters now and I was planning on taking Number Theory and Abstract Algebra next term. I took mathematical cryptography this term and it got me interested in more related math.
ruang··on How Not to Learn Cryptography (2014)
Best courses for mathematical maturity besides the standard CS ones? I'm thinking Algebra, or maybe Real Analysis.
ruang··on Extremely disillusioned with technology. Please help
Lately it's been math majors. Zoom and Stripe founders were math majors.
ruang··on MIT 6.004: Computation Structures
Thank you! I really needed this.
ruang··on MIT 6.004: Computation Structures
Is the site just temporarily down? I was watching one of the lecture videos and when I came back to the site I got a 502 error.
ruang··on Online courses vs. colleges for software engineering
I think derivation proofs are useful (and definition) but other types of proofs such as correctness hasn't helped me as much.
ruang··on Chicken Hypnotism
Tim Ferriss recently had a podcast with a famous Stanford physics PhD on hypnosis https://tim.blog/2019/08/16/safi-bahcall/
ruang··on Sergey Brin’s Resume (1996)
Would be interesting to know which subset of math he thought was most useful. There is just too much to learn.
ruang··on Bootcamps vs. College (2016)
So true, it's the unknown unknowns that tripped me up before going back to get a Masters CS degree.
ruang··on Bootcamps vs. College (2016)
Having a degree confirms you at least knew the math at one point, and could recall is quickly if needed.
ruang··on Pure Maths in Crisis?
Best description I’ve seen! Can sometimes see it in the bimodality of the types of comments too.
ruang··on How to Be Successful
A negative article "How Not to Be Successful" would be interesting, with unobvious observations. It could also include the top reasons why people get rejected from YC.
ruang··on How to Be Successful
Why don't more employees from Google and Facebook start successful companies? They seem to exhibit all of these traits.
ruang··on Harvard Asian-American discrimination case opens with packed courtroom
People are also taking advantage of affirmative action by claiming to be part of a race if they had one relative from that race 10 generations back i.e. Elizabeth Warren. I feel you should have at least 50% of that DNA in order to be able to claim some racially disadvantaged status.
ruang··on Introduction to Differential Equations (2008)
I need the concrete before the abstract just so my mind knows that what I’m seeing is not BS. Because in finance, 95% of the math is BS formulas that have no connection to reality.
ruang··on Stop future-proofing software
David Sacks said in his Twitter that's one of his criteria for investment - "What’s the friction to scale? Can the team solve?"
ruang··on A Conversation with Paul Graham [video]
Much better than vague concept of “MVP”
ruang··on Convincing engineers to join your team
I love how they mention small. I think small problems test for problem solving and understanding while large engineering questions test for knowledge of libraries that anyone can learn. I know I'm probably overinterpreting the use of the word "small" here.
ruang··on Beijing struggles to defuse anger over China's P2P lending crisis
Thanks, that context makes a lot more sense.

So it's the responsibility of smart investors to bail out dumb investors?

Does that still work now?

ruang··on Sam Altman interview on Mixergy
Good suggestion on how you should focus on technology that's 12-24 months out, and not more.
