Curious to see how your essay on volatility will compare to Nassim Taleb's writing on anti-fragility if you are familiar with it. πŸ™‚

Popped up on my feed. Looked at your neckspert profile. About to make the educated guess that Charmander must have been your starter. But you have already answered it. 😬 Anyways, good taste! πŸ”₯

Ultimate Bolognese Sauce – My Two-Day Meat-Sauce Recipe
Ultimate Bolognese Sauce – My Two-Day Meat-Sauce Recipe YouTube video by W2 KITCHEN

I look up Bolognese recipes on YT. Here comes this guy. He adds sardines and soy sauce and else. I feel sth is off but this is not it. I go to the comments. First comment: He wears a white shirt. Bingo. Lesson learnt: Cooking in a white shirt upsets people. m.youtube.com/watch?v=Ec5Y...

The Hundred-Page Machine Learning Book by Andriy Burkov This is companion wiki of The Hundred-Page Machine Learning Book by Andriy Burkov. The book that aims at teaching machine learning in a concise yet systematic manner.

I am currently reading the 100-pp ML book. Have you read it by any chance? Mainly wondering how it compares in terms of scope and level of detail. themlbook.com/wiki/doku.php

Fully agree. Stated as clearly as this, it reminds me of the preface to Le Petit Prince: What you say is obvious to aspiring founders on the outside. But it gets twisted once you get sucked into the vortex of VC, evaluations, etc.

Was about to say that it looks homemade. Like those authentic hole-in-the-wall shops that would serve this over rice in a metal bowl. Definitely do not want it to come across as a backhanded compliment. Anyways, looks yummy! Well done, stranger!

You and Macaulay Culkin are the formative child actors for a nineties kid that grew up watching too much TV. I still idolize Embeth Davidtz and you for your performances in Matilda.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

I like that he used the term 'better angels'. I know it is a common expression. But as a non-native speaker, I strongly associate this with the Steve Pinker book. I find the book helpful to stay optimistic and empathetic, and remind myself of what is ultimately at stake here.

You are right! How did I forget about comments?! 🀦 Distant third place is probably that there is no distinction between ints and floats. For me, this completes the trinity of simple things that would have made JSON so much better.

I feel dumb now because my first thought was simply: XML is too verbose. 🐦 And my gripe about JSON is equally simplistic: Whenever I prettify it, I wish it allowed for trailing commas. πŸ₯²

Fell into a rabbit hole this morning. Apparently, Bradley Cooper looks different now but denies allegations? Not here to judge but would love more honesty. Like data points for parametric regression. Baseline is this, invested this, thus looks like that.

Wondering if this is so shocking since Snowflake is for OLAP. Constraints such as non-nullability are enabled in modern table formats like Apache Iceberg. But not sure how to efficiently enforce unique constraints in a distributed system. Or if FKs are desirable with eventual consistency.

Python Sorted Containers β€” Sorted Containers 2.4.0 documentation

The sorted containers docs have a good write-up on performance, and the implementation is remarkably simple. grantjenks.com/docs/sortedc... Before I read this, my textbook education had taught me to use B-trees in databases, and balanced BSTs in memory, full stop.

BSTs are also great to start thinking about real-life performance. E.g., the Python sorted containers implementation is closer to B-trees than balanced BSTs because (i) sequential access is so much faster than random access, and (ii) two extra pointers per node means fewer elements in L1-3 cache.
