#SciX is created by the #ADS team & operates out of the Smithsonian Astrophysical Observatory under a NASA Cooperative Agreement. Created and developed by scientists, for scientists, SciX builds on decades of open research infrastructure and collaboration: https://bit.ly/CfASciXNews

For #openscience, the key is data ♻️, and everyone has a role!

AI Carpentry? Helping learners make better choices with genAI. In two recent community discussion sessions, we explored what mental model of machine learning/deep learning we could teach to learners already familiar with the basics of programming, to help them sa...

My latest post on @carpentries.carpentries.org blog is a call to action for the community to engage in curriculum development for workshops about genAI. How can we help our target audience make more informed choices about when and how to use it?

Collaborative Git: Teamwork Without the Chaos

Working on code with others can get messy fast. 😵‍💫

Our #CollaborativeGit session teaches you how to work with teammates, contribute to projects, and never fear merge conflicts again. 🚀

Brilliant! This should be made mandatory not only for every college freshman but for every educator, student, scientist, journalist, politician, decision maker, citizen... Preferably once per week, just in case we forget.

This is a big deal! 2i2c is supporting mybinder.org traffic with a BinderHub that is almost 5x cheaper than previous deployments. I think it is a great sign for mybinder.org's sustainability.

Here's a brief explainer (1/x)

list of banned keywords

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

Lukijan mielipide | Meitä tummaihoisia kiusataan jatkuvasti Pysähtyykö kukaan ajattelemaan sitä, miten syrjiminen oikeasti vaikuttaa meihin tummaihoisiin?

"Pahin kokemukseni rasismista oli silloin, kun olin 11-vuotias. Olin pyöräilemässä keskustassa ja olin juuri aikomassa ylittää suojatietä, kun eteeni käveli nainen. Tämä nainen alkoi huutaa minulle ja haukkua minua n-sanalla. Sen jälkeen hän sylki kasvoilleni."

Open-source and FAIR Research Software for Proteomics Scientific discovery relies on innovative software as much as experimental methods, especially in proteomics, where computational tools are essential for mass spectrometer setup, data analysis, and in...

Recently, We saw a discussion on the role of open-source in proteomics. Here, experienced developers & researchers maintaining OS tools for years shared this comment to guide newcomers in the field about OS and its role in the field. 💻 #Proteomics #OpenSource chemrxiv.org/engage/chemr...

Haluatko ryhtyä kotona hiukkasfyysikoksi? CERNin tutkimusdataa v 2010-2016 ladattavissa netistä omia tutkimuksia varten. Siitä vain etsimään uusia alkeishiukkasia. opendata.cern.ch #cern

@teemuroos.bsky.social @hannu-toivonen.bsky.social Saanko kysyä? Onko termistä workflow käytössä suomenkielistä vastinetta? Esim. yhteydessä computational workflow tai workflow language.

🎓: In addition, in Finland, we help teachers bring authentic open data to schools - not only particle physics but all domains according to teachers' needs (not ours!). #digitalskills #dataliteracy

Read about it e.g. in iopscience.iop.org/article/10.1... Credits go to brilliant Peitsa Veteli!

♻️: The #reusability of open data at the research level remains my main interest: #knowledgepreservation through #analysispreservation is needed!
Currently leading the "Data Lifecycle panel" set up by ICFA (International Committee for Future Accelerators).
More about it later!

🤝: I have now passed the CMS OD leadership to @tpmccauley.bsky.social & Julie Hogan: they are doing great🤩
Happy that I forced myself to 📝 all what is involved in the data release preparations - a humbling experience as it exposes all my flaws🫣. #FAIR is for open data but also for how to get there🤷‍♀️

And also 😊 to see how the #opendata experience gained from what we did convinced those who expected trouble

and we could set up new standards in our field🏆

This is what we've done with a small and dedicated team (🥰) during past ten years 🥳

Not going to lie, I'm pretty proud of this💪

I'm new here so a brief introduction:
PhD, experimental particle physicist @cmsexperiment.bsky.social
based at CERN, employed by HIP - Helsinki Institute of Physics (🇫🇮 for those who see flags)
Analysis background in Higgs physics, but long time active in #datapreservation, #opendata, #openscience
