Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

// you need `op` tool for this, download it here https://support.1password.com/command-line/
// create items.json like so:
// op list items | jq > items.json
// then run this script 
// this script outputs uuids of dupes as keyed by item title, create, and modified date,
// feed it into the delete command like so:
// node process.js | xargs -I{} op delete item {}

An introduction to alternative keyboard layouts

This is a post to satisfy your curiosity about alternative keyboard layouts, why some people use them, and whether they're for you. It is intended to discuss the topic in broad terms, but I will share my personal preferences towards the end. Due to time constraints and my own limited knowledge, I will focus on layouts optimized for the English language (ANSI variants, with an occasional nod to ISO).

First off, it's important to understand how much debate there is about how we got here: I will not even attempt to settle the issue of who invented the 'first' typewriter layout, because the modern device had many predecessors going back centuries. The usual legend of typewriter evolution holds that American Christopher Latham Sholes debuted the typewriter in 1868 with a 2-row layout that was (nearly) alphabetical. A horizontal stagger between the rows made room for the lever arms attached to each key:

 3 5 7 9 N O P Q R S T U V W X Y Z
2 4 6 8 . A B C D E

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

# compinit optimization for oh-my-zsh
# On slow systems, checking the cached .zcompdump file to see if it must be 
# regenerated adds a noticable delay to zsh startup.  This little hack restricts 
# it to once a day.  It should be pasted into your own completion file.
#
# The globbing is a little complicated here:
# - '#q' is an explicit glob qualifier that makes globbing work within zsh's [[ ]] construct.
# - 'N' makes the glob pattern evaluate to nothing when it doesn't match (rather than throw a globbing error)
# - '.' matches "regular files"
# - 'mh+24' matches files (or directories or whatever) that are older than 24 hours.

Vue.js and Vuex - best practices for managing your state

Modifying state object

Example

If you have to extend an existing object with additional property, always prefer Vue.set() over Object.assign() (or spread operator).

Example below explains implications for different implementations.
