Streamlining CTA version upgrades
/ Afonso, Joao (speaker) (CERN)
The CTA software versioning numbering scheme distinguishes between standard code releases and “pivot” releases aimed at upgrading the CTA Catalogue schema. This separation provides us with a simple and replicable set of steps for upgrading CTA between any two versions.
This talk will present the strategy for versioning the CTA software, explain how CTA Catalogue schema upgrades are integrated into our release cycle, and how it all ties together with the planning of new RPM releases. [...]

Evolution of Continuous Integration for CTA
/ Buegel, Niels Alexander (speaker)
CTA's Continuous Integration (CI) system has been around since the inception of the project. However, numerous limitations had piled up: the CI setup was monolithic, developments outside of CTA were difficult to test (EOS, XRootD and dCache), the pipelines were slow and large parts of the CI system were not nicely structured. [...]

Scaleway S3 Glacier: tape archiving for the masses
/ HATIA, Saalik (speaker) (Scaleway) ; FLORENSA, Florian (speaker) (Scaleway)
For six years Scaleway offered S3 Glacier-class storage fully operated on mostly powered-off SMR disks.
This enabled us to offer our customers fast restore time while remaining cost effective, using a mix of commodity and custom hardware.
As our S3 service grew, and since we cannot control nor predict public cloud workloads, the former glacier stack was unable to keep up while becoming more difficult to maintain and operate.
Storing on tape presents its own set of challenges, optimising a disk-oriented workflow to suit a tape-based backend, while being unable to predict the immediate needs of our clients.
This presentation will talk about lessons learned and what the Scaleway Glacier future looks like..

The CERN Open Hardware Licence
/ Tacchini, Dane (speaker) (CERN)
The CERN Open Hardware Licence (“CERN OHL”) was developed in 2011 to promote collaboration among hardware designers and to provide a legal tool which supports the freedom to use, study, modify, share and distribute hardware designs and products based on those designs. The second version of CERN OHL released in 2020 provides additional flexibility by introducing three CERN OHL variants – the permissive, the weakly-reciprocal and the strongly-reciprocal, thus enabling the selection of a licence adapted to the needs of each project.

Welcome and introduction
/ Serrano, Javier (speaker) (CERN)
This quick presentation will provide an introduction to the event, whose main purpose is to take designers on a journey from design idea to commercial Open Source Hardware (OSHW) in the CERN context. We start with the importance of Free and Open-Source Software (FOSS) tools for Printed Circuit Board (PCB) design, and a presentation of KiCad, which now benefits from commercial support at CERN [...]

Putting it all together: radiation-tolerant lighting in CERN's Proton Synchrotron (PS)
/ Devine, James (speaker) (CERN)
This talk will present the full lifecycle of an open hardware project from initial design to repeat procurement, and share the most important lessons learned.
One of the most ambitious projects for LS2 was the electrical refurbishment of the PS accelerator. A huge part of this project was the design, development, procurement and installation of the first generation of radiation tolerant LED lights, designed under the CERN open hardware licence. [...]
