NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

Simpler stack / less moving parts
Works directly with ssh, ssh-add and ssh-keygen on most computers
Simpler
Private key can never leave the FIDO device

Cons of FIDO

Can we create a smart contract VM on nodejs using Dat?

Ethereum is a trustless network of VMs which run smart contracts submitted by users. It uses proof-of-work to synchronize state across the network, and has every node execute the contracts in order to verify the state's validity. Each transaction is stored in the blockchain for replayability. Read more about it here.

Ethereum's "trustless network" model has some disadvantages:

Transaction processing is slow - it maxes at roughly 25tx/s right now for all contracts combined.
Every transaction costs money to execute.
The entire blockchain state must be shared across the computing network.
No private transactions.

Introduction

This is about documenting getting Linux running on the late 2016 and mid 2017 MPB's; the focus is mostly on the MacBookPro13,3 and MacBookPro14,3 (15inch models), but I try to make it relevant and provide information for MacBookPro13,1, MacBookPro13,2, MacBookPro14,1, and MacBookPro14,2 (13inch models) too. I'm currently using Fedora 27, but most the things should be valid for other recent distros even if the details differ. The kernel version is 4.14.x (after latest update).

The state of linux on the MBP (with particular focus on MacBookPro13,2) is also being tracked on https://github.com/Dunedan/mbp-2016-linux . And for Ubuntu users there are a couple tutorials (here and here) focused on that distro and the MacBook.

Note: For those who have followed these instructions ealier, and in particular for those who have had problems with the custom DSDT, modifying the DSDT is not necessary anymore - se

These links no longer work. Springer have pulled the free plug.
