This is a proposal for a lightning talk at Reactive Conf. Please 🌟 this gist to push the proposal!
Do you test presentational logic of your components? No? Yes, but you feel like you are writing a lot of dummy tests? You even probably use snapshot tests for that, but don't feel like you make enought value from them..
If so, click 🌟 button on that Gist!
I'll talk how our team is using snapshot testing to iterate faster,
Please 🌟 this gist to vote for this proposal!
No other topic in software development probably has so much controversy as linting.
With a wrong workflow linting can be really a pain and will slow you and your team down. With a proper setup, though, it can save you hours of manual work reformatting the code and reducing the code-review overhead.
Should be work with 0.18
Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !
myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');Those suck for maintenance and they're ugly.

| " How often do you forget which keys you should use to select/modify strings | |
| " in the ' or " or in other pairs? I often use viw/ciw instead of vi'/vi" for | |
| " the first time because it easier for my fingers (but after that I remember | |
| " about vi'). This script allows you always use the same shortcut for all | |
| " cases. When you want to select string in the ' use viv. Do you want to | |
| " select all in the '()'? Use viv. All in the '[]'? Use viv. | |
