[Isolating Differences Between Files][paper]

Advantage over Other Algorithms

The diff output is more specific:

[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.

>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.

if _, err := os.Stat("/path/to/whatever"); os.IsNotExist(err) {

	// path/to/whatever exists

Mutt + isync multiple accounts Unfinished

This is the setup that I use for mutt, I have two google domain account (read as gmail) and an institution where I work and study account. This means I have two gmail accounts and one outlook 365 account that i want to sync and read via mutt.

I want to store all my email locally as I travel a lot and will be in countries without easy internet access. For this I use mbsync (iSync). As it can handle multiple account types easily and efficently.

The setup works this way

[Remote Mail Servers] <= mbsync => [Local Mail Folders]

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

Vim Script for Python Developers

This is a guide to Vim Script development for Python developers. Sample code for the various expressions, statements, functions and programming constructs is shown in both Python and Vim Script. This is not intended to be a tutorial for developing Vim scripts. It is assumed that the reader is familiar with Python programming.

For an introduction to Vim Script development, refer to usr_41.txt, eval.txt and Learn Vimscript the Hard Way

For a guide similar to this one for JavaScript developers, refer to Vim Script for the JavaScripter

This guide only describes the programming constructs that are present in both Python and Vim. The constructs that are unique to Vim (e.g. autocommands, [key-mapping](https://vimhelp.org/map.txt.html#key-m
