Patching is an essential part in server maintenance. For Windows servers and clients you have WSUS to coordinate updates and security patches. But how do you patch Ubuntu, Debian, RHEL or Fedora machines? The linux distro field is very dispersed, how do you do patch all these systems? In this post I will show you how I install package updates and ensure that specific packages cannot be updated using version pinning.

Update Windows Subsystem for Linux

Tue, 30 Jan 2018 10:32:51 +0000

Today I learned that certain Ubuntu package versions are bound to the release version of Ubuntu. For example the only available version of the password store tool pass for Ubuntu LTS 14.04 (trusty) is 1.4.2-3. If you need a newer version you have to update Ubuntu first. Usually this no big deal, however, if you work with Windows Subsystem for Linux (WSL) it is a big deal. The WSL release is bound to the Windows version. In result to update a package you have to update your Windows first.

Download full playlists and all songs by an artist from SoundCloud

Tue, 13 May 2014 07:53:13 +0000

Introduction

First of all I want to apologise for what I’m writing about in this post. SoundCloud is a music platform where you can listen to almost every song for free. This is a great network and only works as long users don’t download the songs from SoundCloud. Great artists advertise their content to get more attention, the last thing they want is that you’ll download their songs. However there’s no way to prevent people from doing so, as you will see not even the guys behind SoundCloud can prevent their content from being downloaded. I’d ask you to donate for or buy the songs from the artists you like on SoundCloud.
