Roam Capture Bookmarklet

Building on the work of the +Roam bookmarklet, here is a version that allows you to capture text from webpages and articles in a few different ways:

It will copy the text automatically. A red "copied!" pill will show in the top right of the page to let you know it worked.
If you do not select anything it will give you only a markdown link to the page
If you select something it will give you the selected text in italics with a markdown link to the page
If you select more than one thing (firefox only I believe) it will give you a markdown link to the page with the selected text as child blocks nested underneath.

To try it, drag this link to your bookmarks and then select text on a page and then click the bookmark.

Super Preliminary Elm - Web Assembly Research

Back in December 2017, I started working on something I called Elmish-Wasm, which was just an experimental repo to compile something Elm-like to Wasm. I made some progress, but the helpful people I talked and I came to the conclusion that most of what I had so far (Haskell and Regex to interpret .elm files into rudimentary wasm) was something the Elm compiler and the Elm AST already did. Writing that code was a lot of fun, but maybe not the most valuable way to explore Elm and WebAssembly. Before jumping back into this project I would like to record the important facts and questions related to compiling Elm to Wasm.

What is Wasm?

A lot of people talk about Web Assembly as if its C++ that runs in the browser. Thats not the case. This belief must come from that fact that C can currently compile to web assembly. Wasm is human-unreadable bytecode. There is a human-readable version of wasm, called wat. It looks like this..

A vision for data interchange in Elm

How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?

These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.

Literature Review

By now there are many approaches to communicating between client and server. These approaches tend to be known within specific companies and language communities, but the techniques do not cross borders. I will outline JSON, ProtoBuf, and GraphQL here so we can learn from them all.
