I have been using a Lenovo Thinkpad X1 Carbon laptop (210 DPI) for four years and a Nokia 8 phone (550 DPI) for a year. I enjoy their HiDPI screens: text is crisp and easy to read. To get a similar experience for my workstation, I bought a pair of Dell P2415Q monitors:

The famous ISP-style mail server tutorial lives here. Learn how to set up your own fully-functional mail server using Postfix, Dovecot IMAP/POP3 and MySQL backend on a Debian server just like your favorite mail or website hosting provider. This guide is a voluntary project with no profit in mind. Go ahead and learn to run your own mail server within hours.

So you’ve just rented a new server, in some random data center, from one of the popular hosting providers. You don’t have physical access to the machine, but you rely on your data to be stored securely on the server. You probably want to encrypt the entire system, even the swap partition. The server needs to be able to decrypt the filesystems to boot, but you don’t want the encryption key to be accessible by it, so nobody with physical access can access your data or even tamper with it.

This article describes how to configure Windows to automate the logon process by storing your password and other pertinent information in the registry database. By using this feature, other users can start your computer and use the account that you establish to automatically log on.

Important The autologon feature is provided as a convenience. However, this feature may be a security risk. If you set a computer for autologon, anyone who can physically obtain access to the computer can gain access to all the computer's contents, including any networks it is connected to. Additionally, when autologon is turned on, the password is stored in the registry in plain text. The specific registry key that stores this value can be remotely read by the Authenticated Users group. This setting is recommended only for cases in which the computer is physically secured and steps have been taken to make sure that untrusted users cannot remotely access the registry.

A couple of days ago an interesting step-by-step guide on how to install Debian with full disk encryption, including /boot, using debian-installer was posted on the debian-boot mailinglist. This reminded me of the steps I used and wrote down a couple of month ago to create a similar setup. These steps describe a full disk (including /boot) encrypted setup on a non coreboot enabled system using the great grml live distro. (And just to be sure I just redid the same setup on a test device with the newest grml release Gnackwatschn):

aenigma provisions a fully functional and out-of-the-box secure XMPP server you can get running today.

It does for XMPP what Mail-in-a-Box has done for email, Streisand for VPNs, and Easyengine for wordpress.

The installation takes you on a 15 minute, clearly worded, step-by-step setup and takes care of everything automagically.

This is a guide to set up a modern XMPP server focused on security and mobile messaging. The whole guide assumes Debian stable running on the server, the fact that you will end up hosting a few of your friends and that you have some basic skills working on a linux command line. Please note that if you’ve followed this guide in the past you might need to have a look at the update considerations

This guide is for people who want to craft a custom Kubernetes cluster. If you can find an existing Getting Started Guide that meets your needs on this list, then we recommend using it, as you will be able to benefit from the experience of others. However, if you have specific IaaS, networking, configuration management, or operating system requirements not met by any of those guides, then this guide will provide an outline of the steps you need to take. Note that it requires considerably more effort than using one of the pre-defined guides.

This guide is also useful for those wanting to understand at a high level some of the steps that existing cluster setup scripts are making.

If you have questions, join us on the kubernetes slack, channel #kubespray.

• Can be deployed on AWS, GCE, Azure, OpenStack, vSphere, Oracle Cloud Infrastructure (Experimental), or Baremetal
• Highly available cluster
• Composable (Choice of the network plugin for instance)
• Supports most popular Linux distributions
• Continuous integration tests

Add-ons extend the functionality of Kubernetes.

This page lists some of the available add-ons and links to their respective installation instructions.

Add-ons in each section are sorted alphabetically - the ordering does not imply any preferential status.

kubeadm helps you bootstrap a minimum viable Kubernetes cluster that conforms to best practices. With kubeadm, your cluster should pass Kubernetes Conformance tests. Kubeadm also supports other cluster lifecycle functions, such as upgrades, downgrade, and managing bootstrap tokens.

Because you can install kubeadm on various types of machine (e.g. laptop, server, Raspberry Pi, etc.), it’s well suited for integration with provisioning systems such as Terraform or Ansible.

kubeadm’s simplicity means it can serve a wide range of use cases:

New users can start with kubeadm to try Kubernetes out for the first time.
Users familiar with Kubernetes can spin up clusters with kubeadm and test their applications.
Larger projects can include kubeadm as a building block in a more complex system that can also include other installer tools.

kubeadm is designed to be a simple way for new users to start trying Kubernetes out, possibly for the first time, a way for existing users to test their application on and stitch together a cluster easily, and also to be a building block in other ecosystem and/or installer tool with a larger scope.

You can install kubeadm very easily on operating systems that support installing deb or rpm packages. The responsible SIG for kubeadm, SIG Cluster Lifecycle, provides these packages pre-built for you, but you may also on other OSes.

There are multiple ways to run a Kubernetes cluster with Ubuntu. These pages explain how to deploy Kubernetes on Ubuntu on multiple public and private clouds, as well as bare metal.

In this guide, we will be setting up a simple Python application using the Flask micro-framework on Ubuntu 16.04. The bulk of this article will be about how to set up the uWSGI application server to launch the application and Nginx to act as a front end reverse proxy.

Distributing software efficiently accross your platform can be difficult. Every distribution comes with a package manager which is usually suited for this task. APT can be relied upon on when using Debian or a derivative.

Unfortunately, the official repositories may not contain everything you need. When you require unpackaged software or more recent versions, it is possible to setup your own local repository.

Most of what is presented here was setup for Dailymotion and was greatly inspired by the work done by Raphaël Pinson at Orange.
