I think many struggle with OLTP relational databases because we do a bad job educating people, and many of our best practices are not actually best practices. RDBMSes can do a lot more than most people think. Wanted to share a few contrarian principles that helped me out w/ them:

We just shipped a new blog post I wrote on the @dagster blog. It's a step-by-step tutorial on how to build a ChatGPT-like bot that can answer technical questions about any GitHub repo using a great new Python library - @langchain - and the @OpenAI API. (1/4)

a few weeks ago, i moved summarize dot tech off of gpt-3.5 and onto @MistralAI's mistral-7b-instruct, an open-source LLM that runs on normie hardware. the model is hosted by @perplexity_ai. it's just as fast, just as high quality, and much cheaper to run. here are the details:

twitter's in the midst of a huge shift towards graphql, and the team has grown to the point that it needs a dedicated manager. i'm pretty sure that twitter is the 2nd largest graphql app in the world after facebook, so if you're interested in managing this team, DMs are open!

Whether react or react native lives or dies doesn’t matter. What’s important is that the programming model pioneered by react lives on.

some principal OOP architect back in the day decided that a URL object must represent the canonical resource in some abstract sense. to do this they need to resolve dns, even to compute the hash code. it is bananas

this is a popular pov but i disagree. you will hire from very different talent pools, and have a very different engineering culture, depending on whether you pick c#, nodejs, or scala
What tech framework you choose is by far the least important thing in building a startup
Which is funny because it’s what everyone seems to spend the most attention and time on
Getting a customer to spend their money by building a product that solves a problem should be priority #1

i wish someone would make a react JSX runtime for tailwind, where every tailwind classname exists as a boolean prop on every html element. so i could do stuff like <div pt6 spaceY4 w24 h24 bgRed100={isFailed} bgWhite100={!isFailed}>...</div> cc @adamwathan

Relational databases like MySQL and Postgres should throw errors when they table scan unless an explicit flag on the connection is set.

one thing that helped @reactjs get adoption early on was we were really nice to people who were mean on the internet, and then they turned into nice people

I think you guys should be way more aggressive in pushing back against this stuff. Throwing out the react programming model and adopting something like signals (or worse, signals plus a dsl) is a huge step backwards and most people haven’t internalized that

I don't understand the useReducer() stans. Seems like it'll result in the same old Redux boilerplate problem where you need to define a bunch of different types for all of your actions. IMO useState() + helper functions is the way to go. Am I missing something?

Before you commit any queries to the codebase, write a script to fill up your local development DB with 100k+ rows, and run EXPLAIN on your query. If it doesn't use that index, it's not ready to be committed. Baking this into an automated test would be better, but is hard to do.

I think one of the reasons JS is so successful is that it has a really strong culture of focusing on cold start performance. Spend some time in JVM land and you’ll quickly appreciate it :)

it turns out that many organizations' Big Data™ can often fit on a single cloud instance. @duckdb is super well poised to step in as the data warehouse in those situations, especially given its features, perf, and testability. however, there's one big problem with it: (1/4)

Diagrams are helpful to have but painful to draw. What if you could generate diagrams from what you already have? From code or project descriptions?

Your dilution math is 10x too low, and you forgot that this is taxed at cap gains not income. Completely changes the story. By my math they’re taking home over a mil after taxes per year. Not bad!
