Configure the protonmail bridge linux client on CentOS server and Fedora

Protonmail on CentOS server

#protonmail #centos #fedora #linux

Before you start

Currently protonmail bridge for linux is distributed as part of an open beta program, but soon it will be made public (https://protonmail.com/bridge/install).

Consider that the bridge linux client requires a paid protonmail account to work.

Tutorial for installing a 64-bit Arch Linux ARM system on the Raspberry Pi 3B+, with an encrypted root filesystem, and the option to remotely unlock it via a pre-boot SSH daemon.

Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

  • probably better performance
  • can run 64-bit software
  • comes without the proprietary video-driver blobs

Complete Guide for Hosting CS:GO Dedicated Servers

Complete Guide for Hosting a CS:GO Dedicated Server

Creative Commons License.

I tested the setup on Debian Stretch (naive installation) and Jessie (LinuxGSM installation). The setup should work on Debian 8 (Jessie), Debian 9 (Stretch) and Ubuntu (16.04). However, If you're running on Windows or other non-debian based Linux OS (e.g. CentOS, openSUSE), this guide doesn't apply to you.

Firing up Latex on macOS

Firing up LaTex on macOS 🔥

As I'm writing this small tutorial, I assume you've read my previous one about setting up macOS, so if for any tool I'll use without explanation, look to that other article.

MacTex

The full version IS NOT MANDATORY, as in the tutorial that follows I installed the smaller version of MacTeX and proceded installing every needed dependency. Installing the complete package is about ~3.5GB of download and ~5GB on disk, the smaller one is just about 80MBs.

Click here to download the complete version or here to download the smaller version.
