BornHack 2021 is almost over at this point. We would like to say farewell for now and see you again at the next event in 2022. We will walk over what we believe has worked and what we believe should change the next event. This is an excellent opportunity to submit ideas for BornHack 2022 while the memories are still fresh. about this event: https://bornhack.dk/bornhack-2021/program/goodbye-world/

Come and meet the network team who will talk about the design and operation of the network at BornHack. about this event: https://bornhack.dk/bornhack-2021/program/state-of-the-network/

I have for a few decades worked in networking and security, and everything seems to have grown. I will try to lay out a path for people who wants to get into networking and security, with some references to pentesting, software security, and related areas. Where to start and which skills you should start learning. I will use my existing courses as a guide. These are taught as part of the of the Di...

In this talk Holger Levsen will give an update on Reproducible Builds of Debian and beyond. He’ll briefly sum up the status in Buster, then present developments in and for Bullseye and give an outlook on Bookworm, what’s planned, being built and wished for! Bullseye will be the third Debian release since work on Reproducible Builds of Debian has really started: we started with the beginning of the...

Ever since trying the Orbital Ion Cannon from C&C red alert, I've had a dream of sending a laser into space (on purpose) - while this certainly would be an interesting backstory, the truth is somewhat more boring... When making cubesats and micro satellites, the data downlink is one of the more difficult and costly things. By moving from traditional radio-based downlinks to a optical system, data...

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. about this event: https://bo...

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 t...

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...

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. about this event: https://bornhack.dk/bornhack-2021/program/netbox-as-ansible-inventory/

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 about this event: https://bornhack.dk/bornhack-2021/program/cactus-comments-web-comments-built-on-matrix/

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 mana...

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 an...

Nachdem ich am Anfang vom ersten Lockdown im Frühjahr 2020 zwei Wochen straight vor lauter Sorgen Kopfschmerzen hatte und fertig war, hab ich mich mit der Situation irgendwie arrangiert. Ich hab zwar etwas vergessen, wie man tanzt oder in die Kneipe geht und Freund*innen umarmt, aber dafür paar andere Dinge gemacht. Zwischendurch bin ich auch auf den Begriff "Scanner"-Persönlichkeit gestoßen, der...

Inspired by Niels Serups inspirational talk about unspectacular personal failures, here is one about my first excursion into the relm of dependently typed programming. When learning about dependent types, one is often presented with cannonical examples such as a list that is parameterized with its lenght. However, dependent types turn out to be quite useful for inferring properties about terms. An...

Matrix ist ein offenes Chatnetzwerk für sichere, dezentrale Kommunikation. Keine Lust mehrere Chat-Clients zu installieren um alle Freunde zu erreichen? Kein Problem, denn Matrix vereint verschiedene Chat-Netze und bringt zusätzlich noch sehr coole Features mit. In diesem Vortrag möchte ich euch näher bringen wie man in Matrix Bots nutzen kann und wie man selbst welche erstellen kann. about this e...

Terminals sind immer noch das Mittel der Wahl für viele. Aber wie in einem Programm robust Tastatureingaben interpretieren? Und wie erkennen welche Funktionen das verwendete Terminal unterstützt? Termpaint ist eine Low-Level-Terminal-Abstraktions-Library, um Entwicklern genau diese Fragen abzunehmen und eine moderne Abstraktion für Terminals anzubieten. Terminals sind immer noch das Mittel der Wah...

Covid-19 took me off the road and I turned back to my trusty guitar. Surprisingly there are many great resources on line to help you learn ,or relearn, how to play. This is a examination of those resources and my ride from extreme mediocrity to modest mediocrity with six stings . I used to travel 25-40 percent of each month as a software evangelist until Covid-19 made me stay home. Then I rediscov...

Schon bisher ist die Ausstattung von IT-Laboren bzw. PC-Räumen an Hochschulen - mit ihren schnell wechselnden und vielfältigen Anforderungen - eine Herausforderung, die wir an der Fachhochschule Burgenland mit unserem "Vlizedlab" (eine Open Source Eigenentwicklung - siehe www.vlizedlab.at) sehr gut bewältigen können. Das Vlizedlab ist seit vielen Jahren in Betrieb, auch an Schulen in Österreich in...

Turris Sentinel is a network security oriented project maintaining a network of honeypot-like probes running on Turris routers. In the last few years we developed an open source framework for data processing and explored several message queuing and storage technologies which powers our data processing pipelines. In this lecture I would like to talk about our experiences with Redis, InfluxDB and Po...
