The development of GCC version 16 is in Stage 4, so a release candidate is likely in April.

Now is a great time to test your project against this new compiler! With SIMDe I found a new crash, and I'm likely to make another bug report.

Reporting bugs in compilers early means they get fixed before official release, and then you don't have to carry a workaround for the bug.

To assist with testing on popular CI services, I backported packages of a recent GCC-16 snapshot to Ubuntu 24.04 (including the cross compilers): https://launchpad.net/~misterc/+archive/ubuntu/gcc-snapshot-latest-lts

More about GCC-16 status: https://gcc.gnu.org/pipermail/gcc/2026-January/247347.html

Official Debian Experimental packages for gcc-16 https://packages.debian.org/experimental/gcc-16

Ubuntu 26.04 Resolute packages for gcc-16 https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test

I can make backports to Debian stable or more recent Ubuntu releases, just ask me!

Apptainer / Singularity people using sandbox (unpacked) directories for your containers: where do you put them? Is there a standard location?

(question is in the context of supporting this in the reference implementation of the @cwl standards: https://github.com/common-workflow-language/cwltool/pull/2166#pullrequestreview-3455182878)

#BioHackEU25 Last week Vedran and Matúš visited me for a head start on this week's BioHackathon. We were kindly hosted by Dr. Sven Twardziok at Charité/BIH. With Vedran we dug into the cwljava library and after I made several fixes he opened https://github.com/sanctuuary/APE/pull/138
To follow on with that I will be finally releasing the cwljava library on the Maven Central Repository.
With Matúš we discussed the ongoing work to expand the edamontology.org to more domains, specifically Earth Observation / Geo. He showed me some previous unreleased work and we scheduled a meeting for today with Lorenz Grouper and colleagues, whom I was recently introduced to by Iacopo Colonnelli as part of our CWL4HPC work.

Fwoah, if I could tolerate PHP then I would be applying for this job with @wikimediaDE https://wikimedia-deutschland.softgarden.io/job/60560805

TIL: 1) the "-###" option to gcc/clang 2) How to find out which compiler options correspond to "-march=native", "-mcpu=native", and/or "-mtune=native"

https://github.com/ccache/ccache/commit/29d24c81f42341f8cb725da3dbca7f7357ecbb40

For example:
gcc -### -E - -march=native |& grep "/cc1 -E"

And because Iacopo nerd-sniped me, I started testing riscv-64 wheels for schema-salad: https://github.com/common-workflow-language/schema_salad/actions/runs/18283289222/job/52051503756?pr=963

With an eye towards the upcoming EOL of Python 3.9, I played with the new Structural Pattern Matching feature in Python 3.10 for some of the CWL projects. It was fun! Anything else that we should try out in Py3.10?

On October 4-5 (yup, next weekend!), @NASA is calling people from around the globe to join this year’s #SpaceAppsChallenge, the largest annual global hackathon. ✨🛰️🚀

I’m (once gain) running the official Local Event for Copenhagen in-person at the Republikken co-working space in Vesterbro: <https://www.spaceappschallenge.org/2025/local-events/copenhagen/>.

⭐Create #SpaceApps teams with a variety of backgrounds and skill sets
⭐Use open data from #NASA and from 14 Space Agency Partners (including @esa) to address challenges (https://www.spaceappschallenge.org/2025/challenges/) we face on earth and in space
⭐Engage and learn from NASA Subject Matter Experts (via a dedicated GitHub Discussions forum: https://github.com/nasa/spaceapps/discussions)
⭐Participate for the chance to win one of the ten Global Awards

And no, it is not just about creating "apps". #SpaceAppsChallenge is not just for coders or scientists. A global finalist from Tajikstan created a comic in 2021 to tell the story of NASA's Lucy Trojan Asteroid Mission. A global winner in 2020 from Peru created mascots to help make learning about earth and space science more fun and welcoming for younger audiences. A global finalist from the US created a children’s storybook that included moving illustrations, sound effects, and engaging music in order to tell the story of Parker, the solar probe.

You can register here: https://www.spaceappschallenge.org/2025/

Also, if you are interested not in participating in the hackathon per se but are interested in (a) being a project judge (there’s a clear rubric I’d go over with you) and help nominate local projects for global prizes, or (b) being a mentor to teams, let me know. 🙂

Computer science, said by Alan Kay IIRC to be better described as process science, as the antidote to Jo Freeman’s Tyranny of Structurelessness.

I.e., computer science being to processes as data science is to data.

> Key highlights:

> * Backwards-compatible, most metadata files can simply upgrade `<https://w3id.org/ro/crate/1.1/context>` to `<https://w3id.org/ro/crate/1.2/context>`
> * Formalisation of profile crate, a mechanism for specialising the core RO-Crate profile
> * New option of detached crate for RO-Crate metadata files outside of a folder-like structure (e.g. as part of an API)
> * Specified how to reference other RO-Crates, including their profile
> * Specified how to retrieve an RO-Crate, using FAIR Signposting
> * See publication "Practical webby FDOs With RO-Crate and FAIR Signposting"
> * Editorial changes throughout with clarifications, improved language and examples
>
> RO-Crate 1.2 constitutes a stable long-term release. For a full list of updates, see the changelog.

Oh man, @tetron , this is such a tragedy. I'm going to miss you buddy, you changed my life!

> If pair programming is a part of your work life—whether it's 5 minutes or 5 hours at a time—you’d be doing us a big favor by taking ~20 minutes to complete the survey:

https://will.understan.de/you/index.php/276389?lang=en

> Context: The Software Engineering research group at @freieuniversitaet n has been studying pair programming in professional software development for about 20 years. While many focus on whether pair programming increases quality or productivity, our approach has always been to understand how it is actually practiced and experienced in real-world settings. And that’s only possible by talking to practitioners or observing them at work.

> Right now, we're conducting a survey focused on emotions and behaviors during pair programming.

> If you find the survey interesting, feel free to share it with your colleagues too. Every response helps!
