A crash course in setting up your Python Reddit bot on Heroku

You'll need to do the following:

You need to make your bot a python app. Do this by making another directory (can be the same name as the regular one) and put all your python code in that, and make an empty file called __init__.py in it as well. See how I structured mine if this isn't clear. In your base directory, create two files: "requirements.txt" and "runtime.txt". The requirements.txt file should be the output of pip freeze (you can run the command "pip freeze > requirements.txt"). If you're not using virtualenv, you'll need to go through after and delete all the lines with packages your code doesn't actually use. Check out mine to see what I mean. Runtime.txt just specifies with python version for heroku to use. Mine just has the line "python-2.7.4" in it. All of this will tell heroku to recognize your bot as a python app.
Make a heroku account and

I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

What's an Effective Engineer?

First set out your build scripts In your package.json scripts and install the gh-pages npm module

"build": "gatsby build",
"test": "echo \"no test specified\" && exit 0",
"preDeploy": "gatsby build --prefix-paths",
"deploy": "npm run preDeploy && gh-pages -d public"

Connect Travis CI to your repo and in the repo settings add an enviroment var call GITHUB_TOKEN with the value of your github token from:

Auto reconnect to wifi when lost connection

Before you start, make sure ip command is available on your system. In modern Linux distributions, ip replaces older ifconfig command. If net-tools package (that includes ifconfig) is not installed and you prefer using it, you can install it via sudo apt-get install net-tools.

Create script file

Use touch /home/pi/wifi-reconnect.sh to create a shell script file, with the following content:

#!/bin/bash

Frontend Technical Interview Prep

EDIT: Well this has been linked now so just an FYI this is still TBD. Feel free to comment if you have suggestions for improvements. Also here is an unrolled Twitter thread of a lot of the tips I talk about on here.

I've been doing frontend for a while now and one thing that really gripes me is the interview. I think the breadth of knowledge of a "Frontend Engineer" has been so poorly defined that people really just expected you to know everything. Many companies have made this a hybrid role. The Web is massive and there are many MANY things to know. Some of these things are just facts that you learn and others are things you really have to understand.

Every time I interview, I go over the same stuff. I wanted to create a gist of the TL;DR things that would jog my memory and hopefully yours too.

Lots of these things are real things I've been asked that caught me off guard. It's nice to have something you ca
