Continuous Integration & Delivery (CI/CD) Unconference

Tuesday, February 5th, Berner Fachhochschule

We are happy to announce an unconference about the topic of Continuous Integration & Delivery (CI/CD). The event is organized by Swiss Alliance for Data-Intensive Services members Zazuko and Berner Fachhochschule. It will take place on Tuesday afternoon, February 5th 2019. We will start at 13:30 and stop latest at 18:00

What is an unconference?

An Unconference is an event where there is no fix schedule defined upfront, the event will be completely participant-driven. The final agenda is created collaboratively by the attendees at the beginning of the unconference. Anyone who wants to initiate a discussion on a topic can claim a time and a space. Some unconference sessions are led by the participant who suggested its topic; other unconference sessions (for example Open Space meetings) are basically open

DINAcon Linked Data Challenges

The goal of the 90 minutes is to get to know to SPARQL and create some useful queries from existing datasets. Your hosts are Pasquale di Donato, Matthias Mazenauer, Cristina Sarasua and Adrian Gschwend.

SPARQL CONSTRUCT comparison

I had some days left on a physical machine we used for an EU FP7 research project so I took the chance to compare 3 triplestores (update: added some more based on comments here) I or my colleagues worked with in the past months. I do not want to imply anything with this test, it's just me playing around and having fun with RDF. If you have any comments, add it here.

Hardware

The test platform comprises a dedicated server, not a virtual machine, with the following specification:

2 x Intel Xeon E5 2620V2, 2 x (6 x 2.10 GHz) (appears as 24 cores in htop)
128 GB buffered ECC RAM

Ceci n'est pas une pipe

I got asked on Twitter on how I would use Content-Location with Linked Data, see https://twitter.com/elfpavlik/status/605693139119153153.

I'm referring to my remark from the Trifid-LD Readme:

Trifid-LD does not care about HTTPRange-14 and neither should you. We consider the extra 303 redirect round-trip a waste of precious response time. You get back what you asked for in content-negotiation.

As you can see later in the text we did think about the Content-Location header but didn't implement it so far. The reason is pretty simple: While I understand the problem (up to some point at least) from a meta-level I fail to see where this is an issue in the real world. I'm just an engineer and maybe I'm oversimplifying things here but as long as no one gives me a clear explanation on why this will lead to real world problems, I will continue to ignore HTTPR
