I wrote this tutorial because I've seen bits and chips of this topic, but never a full tutorial (especially not an up-to-date one).

This tutorial is intented for miners who want to mine Monero (or any other coin supported by xmr-stak) on a Ubuntu based system, with Nvidia cards (note: the tutorial works fine with CPU-only mining, just skip the driver installing part, and use -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF flags for cmake)

I assume You have a fresh install of Ubuntu, make sure Your system is up-to-date

sudo apt update && sudo apt upgrade

Install the latest version of the Nvidia driver avialable in the apt repository (which is 384 as of now)

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your lokal GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like my Deepl.io to act upon a Web-Hook that's triggered that service.

// Start `node d3-server.js`
// Then visit http://localhost:1337/
//
var d3   = require('d3'),
    http = require('http')

http.createServer(function (req, res) {
  // Chrome automatically sends a requests for favicons
  // Looks like https://code.google.com/p/chromium/issues/detail?id=39402 isn't
  // fixed or this is a regression.

Virtual hosts

Let's say you want to host domains first.com and second.com.

Create folders for their files:

#!/bin/bash
#renew ssl letsencrypt certificate on bitnami server
#https://gist.github.com/printminion/6ec2fc0fefaba8e0a98a63a6d73b0802/edit

sudo /opt/bitnami/ctlscript.sh stop apache
cd /home/user/certbot
#./certbot-auto certonly --standalone -w /opt/bitnami/apache2/conf/ -d example
.com -d www.example.com
./certbot-auto renew
sudo cp /etc/letsencrypt/live/example.com/fullchain.pem /opt/bitnami/apache2/conf/server.crt
