The autumn 2019 season is here

Once again it is time for a new season of foss-gbg. We’ve already lined up a couple of speakers with various topics, but we want to know what you are interested in. If you want to hear about something, or speak about something – do get in touch.

We are also looking for venues so if you want to host one of our meetups – reach out and we can set something up.

In the mean time, here are some sneak peaks at what is coming during the autumn.

One of the topics planned is a talk on LabGrid – a Python based framework for testing and automation.

Another topic that is on the list is Godot Engine – an open source game engine that is gaining a lot of traction.

foss-north IoT and Security Day

On October 21st, the first foss-north event outside of Gothenburg will take place at the WTC in Stockholm. There, we will spend a day with the theme IoT and Security.

The Call for Papers is open until August 18, and the final programme will be available in the beginning of September.

So – make sure to get your talk submitted, and save the date so that we can meet in October!

OPENHACK in Gothenburg

Are you a creative problem solver or enjoy coding? Do you have a passion for working with humanitarian issues? If the answer to these questions is yes, then join OPENHACK for their hackathon the weekend of 24-26th May!

OPENHACK started as a project within engineers without borders and is a collaborative community where ideas and knowledge are being exchanged in order to solve humanitarian challenges through open source development. Our hackathons serve as the foundation of our community where physical meetings take place and innovations are sparked to life. This is where we bring tech volunteers, aid organizations, social actors, and sponsors together in the same building to work together.

For 48 hours, developers, designers and motivated people from all over Sweden will gather for a hackathon in Gothenburg. The focus will be to leverage Open Source code to solve challenges society faces.

foss-north 2019: Community Day

I don’t dare to count the days until foss-north 2019, but it is very soon. One of the changes to this year is that we expand the conference with an additional community day.

The idea with the community day here is that we arrange for conference rooms all across town and invite open source projects to use them for workshops, install fests, hackathons, dev sprints or whatever else they see fit. It is basically a day of mini-conferences spread out across town.

The community day is on April 7, the day before the conference days, and is free of charge.

This part of the arrangements has actually been one of the most interesting ones, as it involves a lot of coordination. I’d like to start by thanking all our room hosts. Without them, the day would not be possible!

The other half of the puzzle is our projects. I am very happy to see such a large group of projects willing to try this out for the first time, and I hope for lots and lots of visitors so that they will want to come back in the future as well.

The location of each project, as well as the contents of each room can be found on the community day page. Even though the day is free of charge, some of the rooms want you to pre-register as the seats might be limited, or they want to know if they expect five or fifty visitors. I would also love for you to register at our community day meetup, just to give me an indication of the number of participants.

Also – don’t forget to get your tickets for the conference days – and combine this with a training. We’re already past the visitor count of the 2018 event, so we will most likely be sold out this year!

foss-north 2019: Training Day

The 2019 incarnation of foss-north is less than a month away. This year we’re extending the conference in two directions: a training day and a community day. This time, I wanted to write about the training day.

The training day, April 10, is an additional day for those who want to extend the conference with a day of dedicated training. I’m very happy to have two experienced and well known trainers on side: Michael Kerrisk and Chris Simmonds. Both has years of training experience.

Michael will teach about the details in dynamic linking. The topic may seem trivial, but when you start scratching the surface, there are a lot of details to discover such as how to handle version compatibility, how symbol resolution really works, and so on. You can read more about the Building and Using Shared Libraries on Linux training here.

Chris will run a getting started with embedded Linux training. Using BeagleBone Black devices the participants will learn how to build linux for the target, how to get devices such as GPIO and i2c working and more. You can read more about the Fast Track to Embedded Linux training here.

The best part of enrolling for training at foss-north is that you also get full access to the two conference days, and that you help fund the conference itself. If you are interested, check out the tickets page.

Friday and foss-north

What a great Friday! The entire schedule for foss-north 2019 is done.

Make sure to get your ticket now! We’re filling up fast. 123 tickets are already gone!

foss-gbg 2019-02: Containers without Docker

It is time for the first foss-gbg of 2019 and this time we will listen to Anders Björklund speaking about Containers without Docker.

In this presentation Anders will talk about the Podman and Kubernetes projects, and show how to run Linux containers – without using a Docker daemon. It will include a brief introduction and a historic background of container technology, as well as some demonstrations on how you can run it locally.

Linux containers are technologies that allow you to package and isolate applications with their entire runtime environment – all they need to run. Containers share the operating system (OS) kernel and therefore do not require an OS per application, requiring less resources than virtual machines.

Kubernetes (k8s) is an open-source container orchestration system for automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery, and was originally released by Google in 2014.

And some words about the speaker:

Anders Björklund is a system developer working with continuous integration and continuous delivery using distributed build systems based on Linux. He has been working with Linux and containers for a long time, and is part of the Docker Machine community and a maintainer of Kubernetes Minikube.

Our host for the evening will be Scionova who provides some lighter food and beverages.

foss-gbg 2018-11: Mender and hacking

It is time for the November foss-gbg. We will meet on the 14th and listen to Mirza Krak talk about Mender, followed by a hacking workshop by Philip Karlsson, so make sure to bring a laptop!

Robust software updates on Embedded Linux devices is complex, and doing robust software updates over-the-air adds to the complexity. The hardships come of course from the embedded environment which differ in many ways compared to desktop or server Linux installations, where you must handle poor mobile network connectivity, sudden power-loss and never leave a device in a unusable state (brick) when doing the update OTA.

There are a lot of examples that have gotten attention in media, where unstable software update solutions have caused real-life problems which could have been mitigated by a robust software solution that is able to handle the corner cases that exist in the embedded environment.

In this talk Mirza Krak will present Mender, Apache 2.0 licensed end-to-end software update solution. This is a deep-dive session that will cover:

– project ecosystem and community
– technical insights
– security insights

And will of course include a mandatory demo.

Mirza Krak is currently part of the open source project to deploy OTA software updates to embedded Linux devices. He is an embedded Linux solution specialist with seven years of experience in the field with expertise in within Board Support Package development which ranges from hardware bring-up, boot-loaders, Linux kernel and build systems (Yocto/OE-core).

Mirza was an Mender community member for a couple of years which led to an employment in 2018 to continue to work on the Mender project full-time.

Mirza has spoken at various conferences including Embedded Linux Conference and foss-north.

The hacking workshop starts with the MiGiC Guitar to MIDI Converter and focuses on how the free software x64dbg can be used to understand how the copy protection to MiGiC was circumvented.Shortly after the commercial release of MiGiC 1.0, the product was found cracked at one of the more known torrent pages. Since development hours were spent trying to protect the product he became curious in how the attackers broke the protection. In order to investigate this the open source debugger / disassembler x96 dbg was acquired to perform an analysis of both the cracked and uncracked binary.

In the session Philip will show you parts of the analysis as well as presenting three so called ”crackmes” that you will get the opportunity to find weaknesses in using the x64dbg tool. Therefore, its a good idea to bring a PC so you can use the tool yourself.

The venue host for the evening are ictech. They will provide lighter snacks and beverages, as well as the location.
