The RasPiGNSS “Betelgeuse” is an expansion board or module (also known as a “HAT”) for the well-known Raspberry Pi mini computer.
It enables precise positioning tasks to be performed on the Raspberry Pi, which is due to its miniature size and modest power consumption ideally suited as a mobile GNSS recording and navigation device. Using this HAT with suitable software, the Raspberry Pi is capable of receiving and processing signals from the GPS (“Navstar GPS”), GLONASS, GALILEO, and BEIDOU navigation satellite systems.
Mit den XBee Modulen können verschiedene Netzwerkarchitekturen aufgesetzt werden. Ich verwende nur eine direkte Verbindung zwischen den beiden Modulen. Dieser Verbindungstyp ist voreingestellt und funktioniert auf Anhieb mit den XBee Pro Modulen. Natürlich kann man hier noch eigene Einstellungen vornehmen wie der Name der Verbindung bzw. das Netzwerkes heißen soll. Das empfiehlt sich wenn mehrere XBee / ZigBee Netzwerke in direkter Nähe zueinander betrieben werden. Ich benötige die Datenübertragung zwischen meiner Basistation und der mobilen Einheit für die genaue differential GPS Positionierung mit der RTK Bibliothek meines Roboters.
Als erstes werden einfach die XBee Pro Module auf die XBee Explorer USB Adapter gesetzt und via USB-Kabel am Raspberry Pi angeschlossen. Ich habe meine beiden Module jeweils an die Basistation und an die mobile Einheit angeschlossen.
Within Temptation joined forces with Tarja for the first single of the band’s new studio album to be released in January 2014. The cooperation is the lead single of the “Paradise (What About Us?)” EP, which is available now!
"Shot in the Dark" is the third single of Within Temptation 's album "The Unforgiving". Check www.within-temptation.com for more information about the song!
This is the music video of Within Temptation - Faster. The video derives from Within Temptation's "Faster & Mother Maiden Short Film". Listen to all essential WT songs here: https://www.lnk.to/wttp
Within Temptation's fifth studio album "The Unforgiving" is based on the comic storyline, therefore the band has released three short films as well. These short films, Mother Maiden, Sinéad and Triplets are all followed by a band performance and all together, form a dark and compelling tale of life, love, revenge, rage, and regret. The first movie, titled "Mother Maiden", ties in with the band's first single & video for 'Faster', introducing the main characters of the narrative.
An afternoon rooftop show above the Republic liquor store at 7th and Main was shut down by police as a result of the huge crowds that descended on downtown Los Angeles to see the band perform the opening track from The Joshua Tree album in March 1987 for this video by Meiert Avis.
It’s vital to test new technology before rolling it out into your production environment. I like to use Python virtual environments provided by the venv module for developing and testing Ansible playbooks and features. Instead of using the default Python and Ansible commands installed on your system, you can easily set up multiple Python environments and test different versions of Ansible and its component libraries.
Virtual environments are like a virtual machine or Linux chroot, but they create an isolated structure of lightweight directories separated from actual Python system directories. That means you can have different sets of Python environments, each with different versions of modules, files, or configurations.
Ansible is based on Python and leverages many Python modules and plugins. When you test something new, it could require you to update a module that your Ansible installation depends on. Upgrading a component that your production environment depends on defeats the purpose of testing. Still, you can have different versions of Ansible and other important Python modules in a dedicated test directory with a virtual environment.
Ansible Tower 3.0 and later uses virtualenv. Virtualenv creates isolated Python environments to avoid problems caused by conflicting dependencies and differing versions. Virtualenv works by simply creating a folder which contains all of the necessary executables and dependencies for a specific version of Python. Ansible Tower creates two virtualenvs during installation–one is used to run Tower, while the other is used to run Ansible. This allows Tower to run in a stable environment, while allowing you to add or update modules to your Ansible Python environment as necessary to run your playbooks. For more information on virtualenv, see the Python Guide to Virtual Environments and the Python virtualenv project itself.
By default, the virtualenv is located at /var/lib/awx/venv/ansible on the file system but starting with Ansible Tower 3.5, you can create your own custom directories and use them in inventory imports. This allows you to choose how you run your inventory imports, as inventory sources use custom virtual environments.
Tower also pre-installs a variety of third-party library/SDK support into this virtualenv for its integration points with a variety of cloud providers (such as EC2, OpenStack, Azure, etc.) Periodically, you may want to add additional SDK support into this virtualenv, which is described in further detail below.

How to quickly learn new programming languages and frameworks. Plus, an dive into HDFS and how it works.
Ein paar Bilder von meiner ersten TT. Onboard war nicht erlaubt :(
es wird aber ein richtiger Film entstehen, wo auch Onboardaufnahmen und meine ganze Story von der Garage bis zum Rennen gezeigt wird.....
Der Macau GP führt durch die Häuserschluchten der asiatischen Metropole. Irre Aufnahmen vom Schweizer-Steier Horst Saiger im Sattel seiner 10er Ninja. Gewaltig!
This repo hosts the openstack.cloud Ansible Collection.
The collection includes the Openstack modules and plugins supported by Openstack community to help the management of Openstack infrastructure.
NOTE: This solution should only be used in non-production environments as a method to get familiar with Ansible. For production use, I recommend installing Ansible on a dedicated Linux server.
An automated deployment tool is a must have for any IT environment. In my lab, that’s Ansible. I’ve used Ansible in my lab to automate VM deployment/destruction, adding SSH keys for remote access to my servers, joining/leaving AD domain, and monitoring the newly deployed VMs. This is very useful as I frequently deploy/destroy VMs for testing a specific use case.
For a Windows admin, Ansible can seem daunting… For one, it runs on linux. Second, it’s based off of Python. I’m here to tell you, it’s not that difficult. In fact, did you know that Ansible is one of the few configuration management tools out there that can easily/natively use PowerShell code?
In this post, I’m going to review the steps involved in getting Ansible installed & running on Windows Server 2019. While install times may vary due to lab resources and internet speed, I’m able to complete the steps outlined below for installing Ansible in a little over 20 minutes.
