For apps built before the image_processing gem became the default, the migration will involve two steps:

1. Migrating to the image processing syntax while still using ImageMagick;
2. Switching to Vips and updating the compression options;

Migrate to the image processing syntax

Before changing from ImageMagick to Vips, it's better to first test the new syntax and ensure everything is still working.

1. Move everything that has to do with compression to a saver hash:

variant(format: :jpg, strip: true, quality: 80)

Install and use pip on macOS without sudo / admin access

Most recently tested on macOS Sierra (10.12.6)

1. Download the installation script; curl https://bootstrap.pypa.io/get-pip.py -o ~/Downloads/get-pip.py
2. Run the installation, appending the --user flag; python ~/Downloads/get-pip.py --user. pip will be installed to ~/Library/Python/2.7/bin/pip
3. Make sure ~/Library/Python/2.7/bin is in your $PATH. For bash users, edit the PATH= line in ~/.bashrc to append the local Python path; ie. PATH=$PATH:~/Library/Python/2.7/bin. Apply the changes, source ~/.bashrc.
4. Use pip! Remember to append --user when installing modules; ie. pip install <package_name> --user

Setting up RetroArch on a Raspberry Pi

I just put the finishing touches on my Raspberry Pi 3 emulation machine running RetroArch. I was not a huge fan of RetroPie due to the reliance on Emulation Station - more moving parts meant that there were more things that could potentially break. I just wanted something that would run raw RetroArch, no frills.

This tutorial is mostly recreated from memory and was most recently tested with a Raspberry Pi 3 running Raspbian Stretch and RetroArch 1.7.7. If there is a mistake or a broken link, PLEASE message me and I will fix it.

Step 1: Install Raspbian

I used Raspbian Stretch Lite from this page. Write the image to your SD card using something like Win32 Disk Imager, or if you're using OSX/Linux follow a tutorial on how to write the image using dd.

Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.

Answering the Front-end developer JavaScript interview questions to the best of my ability.

• Explain event delegation

Sometimes you need to delegate events to things.

• Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

• Explain how prototypal inheritance works.
