This is what I’ve been up to in August 2019:
I finished the RLMeta VM article. When working on it, I noticed that error handling has not gotten much love. I want to improve it and write about it in another article.
I found Build Your Own Text Editor that explains how to build a text editor by showing and explaining incremental patches. I found the approach interesting.
The above made me think about if programs could be organized in features without the use of literate programming. That would require some kind of plugin architechture where features could be plugged in independent of eachother.
I worked on porting Timeline to Python 3. It is a work in progress, but the application now starts. I have a few items left on my TODO list that I want to complete before considering the port done. I ran into a problem that I blogged about. An another one in progress.
I found this tweet by Michael Feathers interesting:
Fred Brooks said that software is best when it looks like it was designed by one mind.
Mob programming is an attempt to create one mind of many.
Quality goes down as the number of people touching code independently goes up.
Interesting constraint problem.
And a follow up:
Interesting parallel to Alan Kay’s bifurcation of languages into “Agglutination of features” vs. “Crystallization of style.”
The former are almost always defined by committee, the latter by solo designers or very small, tight teams.
And another follow up:
There are quality OSS projects that are made up of individual contributors and a distributed review process. It’s possible for independent workers to maintain and extend a codebase, as long as they buy into a shared style and a shared philosophy. Process matters though.
How can we build software so that it appears to be desgined by a single mind?
I wrote some code for an upcoming article on parsing left associative operators in RLMeta.
I read some of Eli Bendersky’s articles on parsing:
One of them led me to read Bob Nystrom’s article Pratt Parsers: Expression Parsing Made Easy.
I want to learn more about JIT compilation. As I read Hello, JIT World: The Joy of Simple JITs describing a JIT compiler for Brainfuck I thought: Is JIT-ing byte code just getting rid of the interpreter loop? I’m not completely sure of the big picture yet. And how does a tracing JIT compiler differ from a regular JIT compiler. Brainfuck seems to be a popular example in JIT articles.
I read about Cython and though that I should try it for RLMeta VM. Should be quite easy to port it to C and make incremental performance improvements.
