I couldn't find a comprehensive list of links for the RC2014 so I started one. Suggestions welcome.

Documentation

• RC2014 Website - descriptions of all official RC2014 boards
• RC2014 Github Repo - official ROMs and example code
• RC2014 CP/M Guide - guide to setting up CP/M on the RC2014
• Decoding RC2014 ROM Labels - explanation of what RC2014 ROM labels mean
• RC2014 Module Template - Kicad template for building RC2014 boards

Performance on Synology RAIDs

(especially while expanding)

Warning: The exact commands may not match for your particular linux OS / Synology(NAS) device. I had to customize the commands after exploring my particular system's setup.

If you're new to linux, or this is a new piece of hardware / a new synology device, jump down to the section called "Inspecting a setup"

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Russian translation of this article can be found here, contributed by Timur Demin.
• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
