LLM Introduction: Learn Language Models

Purpose

Bootstrap knowledge of LLMs ASAP. With a bias/focus to GPT.

Avoid being a link dump. Try to provide only valuable well tuned information.

Prelude

Neural network links before starting with transformers.

ESLint rules for migrating projects from CommonJS to ESM

ESLint rules

The ESM standard is considered stable in NodeJS and well supported by a lot of modern JavaScript tools.

ESLint does a good job validating and fixing ESM code (as long as you don't use top-level await, coming in ESLint v8). Make sure to enable the latest ECMA features in the ESLint config.

Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

Advanced memoization and effects in React

Advanced memoization and effects in React

Memoization is a somewhat fraught topic in the React world, meaning that it's easy to go wrong with it, for example, by [making memo() do nothing][memo-pitfall] by passing in children to a component. The general advice is to avoid memoization until the profiler tells you to optimize, but not all use cases are general, and even in the general use case you can find tricky nuances.

Discussing this topic requires some groundwork about the technical terms, and I'm placing these in once place so that it's easy to skim and skip over:

  • Memoization means caching the output based on the input; in the case of functions, it means caching the return value based on the arguments.
  • Values and references are unfortunately overloaded terms that can refer to the low-level implementation details of assignments in a language like C++, for example, or to memory

Optimization

Optimization

Correctly prioritizing and targeting performance problems and optimization opportunities is one of the hardest things to master in programming. There are a lot of ways to do it wrong: by prematurely optimizing non-bottlenecks, or preferring fast solutions to clear solutions, or measuring problems incorrectly.

I'll try to summarize what I've learned about doing this right.

First, don't optimize until there's an issue. And issues should be defined as application issues: performance problems that are either detectable by the users (lag) or endanger the platform – i.e. problems that cause downtime, like out-of-memory issues. Until there's an issue, don't think about peformance at all: just solve the problem at hand, which is "creating value for the end-user," or some less-corporate translation of the same.

Second, only optimize with instruments. By instruments, I mean technology that lets you decipher which sub-part of the stack is the bottleneck. Let's say you see slowness around fet

import R from "ramda";
var divisibleBy = R.curry(R.pipe(R.flip(R.modulo), R.equals(0)));
var fizzbuzz = R.map(
R.cond([
[R.both(divisibleBy(3), divisibleBy(5)), R.always("FizzBuzz")],
[divisibleBy(3), R.always("Fizz")],
[divisibleBy(5), R.always("Buzz")],
[R.T, R.identity]
])
);

Do we need types in JavaScript? Or maybe not?

This is my lightning talk submission to ReactiveConf 2018 https://reactiveconf.com/

In this talk, I want to share my experience gained during the development of frontend applications in several programming languages.

I think it's not a secret for anybody that developing large JavaScript applications is not so easy as it seems at first glance. We all want something simpler and more reliable. Therefore, many developers and even entire companies switch to different, compiled in JavaScript, programming languages. The bulk of such transitions is accounted for TypeScript and flow, and often, developers faced with more problems than they were before.

I wasn't the exception. Moving to a new project, I started using TypeScript and was disappointed. Luckily in my next project I used ClojureScript and it was like everything is illuminated!

Introduction To Flow

Introduction To Flow

Intended for developers interested in getting started with Flow. At the end of this introduction, you should have a solid understanding of Flow and how to apply it when building an application.

Covers all the basics needed to get started with Flow.
