Normcore LLM Reads

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

Foundational Concepts

Pre-Transformer Models

ES2015
Optimisation
proper tail calls (tail call optimisation)
Syntax
default function parameters
rest parameters
spread syntax for iterable objects
object literal extensions
for..of loops
octal and binary literals

Everything I Know About UI Routing

Definitions

  1. Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
    1. pathname - The "file/directory" portion of the URL, like invoices/123
    2. search - The stuff after ? in a URL like /assignments?showGrades=1.
    3. query - A parsed version of search, usually an object but not a standard browser feature.
    4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
    5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Gram Schmidt Process to orthogonalize a matrix's columns using NumPy
#!/usr/bin/env python
import numpy as np
import numpy.linalg as la
def orthogonalize(U, eps=1e-15):
"""
Orthogonalizes the matrix U (d x n) using Gram-Schmidt Orthogonalization.
If the columns of U are linearly dependent with rank(U) = r, the last n-r columns
will be 0.

Guide to Developing Addons and Blueprints for Ember CLI

Converting libraries to Ember CLI addons

In this guide we will cover two main cases:

  • Ember specific library
  • vendor library

Ember library

The Ember library will assume that Ember has already ben loaded (higher in the loading order) and thus will assume it has access to the Ember API.

A light comparison between Rust and Java generics and type system features.

Introduction

If you are familiar with Java's generics, and are coming to Rust, you might be lead to assume that its generics are working the same way.

However, due to the different type systems, and different implementation details, there are quite a few differences between generic code in both languages.

This document tries to give a short summary about those differences:

Core functionality

Falsehoods programmers believe about prices

  1. You can store a price in a floating point variable.
  2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
  3. All currencies are subdivided in decimal units (like dinar/fils)
  4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
  5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
  6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
  7. For any currency you can have a price of 1. (ZWL)
  8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)
