Ever wanted to build and control a 3-5 meter high flame ? Even higher ? Than this is the talk for you!

Want to know how to build it safely, not blow up yourself in the process and enjoy making your own flame effects to be used on hackercamps/steampunk events/festivals ?

It (re)-uses readily available materials and improvements can be made to suit your own requirements.

Mike is currently working on a book who aims to uncover the story behind a rare Danish built and designed series of computers called the "ICL Comet", and yes ... you might wonder, "ICL is not a danish company" - and you would be right, the machine was sold by ICL, but build, designed and produced by different small Danish Companies.

I have spent three years collecting sources for this books, and the project just exploded in scale and that in itself has become a great story, which I am going to tell you about.

If you like old computers you most definitely want to attend to my talk!

The Update Computer Club was founded in 1983 as a student club at Uppsala University. It aims at connecting people who are interested in all kinds of computer related topics such as hardware, software, running modern or historic computers, computer architechtures, operating systems, or programming. Over the years the club has collected a large amount of historic hardware that documents the history of computing in Sweden. The collection includes a DECSYSTEM-2060, a Cray Y-MP EL, a Symbolics 3650, and a (mostly) working PDP-12. With the upcoming move of the Uppsala University IT department to a new building Update is at risk of losing its rooms, and therefore its collection. We need your help to preserve this bit of computing history!

I will quickly touch on what NetBox is and why we have been using it as inventory for Ansible on our on-prem systems at QuickPay.

Then show/explain some of the issues that we've had to work around.

Cactus Comments is a federated comment system for the open web built on Matrix.

It is GPLv3 licensed, written in Elm, and we host a public backend that's free (as in beer) to use.

Check it out and play with the demo at: https://cactus.chat

In this talk, I introduce the digital ride-hailing apps in Indonesia, Gojek and Grab, and show how they evolved from transport to a broader platform of financial services, including the private issue of ‘e-money’ for their integrated payment systems GoPay and OVO. I examine how they advocate for the expansion of cashless so-called peer-to-peer (P2P) payment systems, and use algorithmic labour management to mobilise their driver fleets to facilitate the use of digital money by customers of the app. I argue that promoting the notion of peerhood by the companies both obfuscates how their apps configure users to participate in new hierarchical exchange relationships, as well as minimizes the companies’ role as intermediary, and how the transactional constellation of P2P camouflages the financial interests that these companies have in generating platform activity. Through this work, I show that the exchange of digital money through these ride-hailing apps constitutes far more than the financial transaction and contains much more than can be summarized in an elegant acronym.

Eine Groupware mit integrierten Online Office verlegt das Office in den Browser. Nicht nur für das Corona-Home-Office, Orts- und Clientunabhängig.

In EGroupware kann Collabora Online als klassisches Online Office und/oder zum Erstellen von Dokumenten genutzt werden. So können Formulare, Protokolle, Zeitnachweise, etc. direkt aus EGroupware erzeugt, geteilt und versendet werden.

Der integrierte Dateimanager/Fileserver (mit Filesharing) und Collabora Online (COOL) ermöglichen das gemeinsame und ortsunabhängige Bearbeiten von Dokumenten. Externe können ebenfalls Dokumente bearbeiten, Verzeichnisse können per SMB, WebDAV oder FTP eingebunden werden und per WebDAV kann von Clients/Dateimanager zugegriffen/geöffnet werden.

EGroupware stellt fast alle Felder (auch die benutzerdefinierten) als Variablen zur Verfügung. Diese Felder werden, eingefügt in ein Dokument/Tabelle/Präsentation/Zeichnung (oder E-Mail), bei Aufruf gefüllt.

So ist in vielen Fällen bereits ein digitaler Workflow ohne viel Aufwand oder spezielle (Branchen-)Software möglich.

Traditionally, individual servers are provisioned with Foreman/ Katello and they can be configured with Ansible, Puppet and Salt which is a host centric deployment. However, a modern application typically consists of multiple services running on different servers but connected to each other. The new plugin Foreman_acd defines application centric deployment and describes an approach to provision and configure hosts to run an application which requires predefined set of services.

This presentation compares host centric and application centric deployment, talks about how you can seamlessly deploy the application with only few clicks, a user friendly approach to utilize your ansible playbooks directly from Github or Gitlab, import/export your application services and configurations rather than creating it in systems from scratch, and how you can vertically and/or horizontally scale up your application fast.

The plugin Foreman_acd is a recently released open source Foreman plugin to deploy your applications containing multiple services and interconnected servers with only few clicks.
