Preface

I owe my very rapid learning journey in the world of ConfigFs to several key sources which aren't necessarily relevant to this result, but I feel deserve a mention anyway.

This really demystified configfs for me, and stopped me being afraid of it: http://events.linuxfoundation.org/sites/events/files/slides/USB%20Gadget%20Configfs%20API_0.pdf
I borrowed heavily from this Mindstorms EV3 script: https://github.com/ev3dev/ev3-systemd/blob/ev3dev-jessie/scripts/ev3-usb.sh
Desperately trawled this thread for answers: https://answers.microsoft.com/en-us/windows/forum/windows_10-networking-winpc/windows-10-vs-remote-ndis-ethernet-usbgadget-not/cb30520a-753c-4219-b908-ad3d45590447?auth=1

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

Poomels Battlefield 4 Config

This is my constantly updated BF4 config.

Put user.cfg in ...\Origin Games\Battlefield 4 !

Put profsave_profile in C:\Users\$USER\Documents\Battlefield 4\settings !

Project Title

One Paragraph of project description goes here

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

This guide is a best-effort to configure a system with just debootstrap.

It has been updated so as not to be actively incorrect as of June 2022, when I realized it was still being used, but it was first written in 2015 and I can't guarantee that it's not missing essential parts of the process.

If it breaks, you get to keep both pieces

Download a Debian live standard CD: https://cdimage.debian.org/cdimage/release/current-live/amd64/bt-hybrid/
Login with user:live (if needed, it will probably automatically login)
Check that you have internet with ip a. If you're using ethernet it should already be connected, otherwise you'll need to configure interfaces(5) and probably wpa_supplicant(8)
