Proxy Traps Cheat Sheet

There are various shenanigans around the Proxy API, including issues with Array.isArray and Object.ownKeys so that this gits purpose is to describe all the undocummented caveats to help anyone dealing with all possibilities this half-doomed API offers.

The 3 + 1 Proxy Types

• object: any non primitive value can be proxied but apply and construct traps won't work with it. If the object somehow wants to represent an array without being one, it's impossible to survive Array.isArray brand check (it will be false) and with ownKeys the target needs to have a non configurable length property or it will also fails once reached
• array: it's like object but it survives the `

WebReflection

This gist is a simple no-brainer description of the 3 ways (actually 2.5) the Web handle events.

<tag onclick />

The declarative inline HTML event listener is mostly an indirection of DOM Level 0 events, meaning this simply uses the equivalent of tag.onclick = listener behind the scene.

rsms

Common terminology found in across literature and implementations:
  Page
    Region of memory. Usually 4096, 8192 or 16384 bytes
  Page Frame
    Same as a Page but when talking about physical memory. Same size as a Page.
  Page Table
    Per virtual address space table mapping virtual addresses to Pages.
  Page Directory
    Like Page Table and is often the same thing. The first level of Page Tables.
  PTE - Page Table Entry

The Rise of "Worse is Better"

By Richard Gabriel

I and just about every designer of Common Lisp and CLOS has had extreme exposure to the MIT/Stanford style of design. The essence of this style can be captured by the phrase "the right thing." To such a designer it is important to get all of the following characteristics right:

Simplicity-the design must be simple, both in implementation and interface. It is more important for the interface to be simple than the implementation.

• Correctness — the design must be correct in all observable aspects. Incorrectness is simply not allowed.
• Consistency — the design must not be inconsistent. A design is allowed to be slightly less simple and less complete to avoid inconsistency. Consistency is as important as correctness.

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)
