From early morning to late evening; from registration to reception: it's a wrap for the first day of #ECMTB26! Looking forward to more exciting talks, discussions, and the first round of poster presentations tomorrow!

Early morning: fully staffed registration desks. Organisers and student helpers waiting for participants to pick up their nametagsBusy gathering next to the conference office after a plenary talkWelcome Reception: musical performance of Timber (Michael Gordon) by STUDIO PERCUSSION GrazLate evening, welcome reception: social gathering in the main building courtyard

this was actually quite fun to build; short-ish share links for a static page / no backend or database. :-) (no credit for ui/ux for me, that was all @anja.codes)

Slowly getting worried our ticket might have gotten drowned over Christmas + New Year's... still hoping for the best that our stuff can be recovered. 🤞🍀

It's been about 2 weeks since our GitHub organization has been deleted, we're still working on resolving this and are waiting for our friends from @github.com to get back to us. In the meantime, find a mirror of some of our main repos over at codeberg.org/ManimCommunity!

It's pretty hard to follow up to cool number years like (20 + 25)² = 2025, but I hope you have a great start to 2¹¹ - 2·11 = 505 + 506 + 507 + 508 = 2026. Happy new year! 🥂🍾🎉 (Bonus fun fact: 2026 is the number of disconnected 4-regular graphs on 17 vertices, via oeis.org/A033483 🧐) #mathsky 🧮

📢 WE HAVE A NEW NAME We are excited to share that VSC has undergone a slight rebranding and will now operate under a new name: 𝗔𝘂𝘀𝘁𝗿𝗶𝗮𝗻 𝗦𝗰𝗶𝗲𝗻𝘁𝗶𝗳𝗶𝗰 𝗖𝗼𝗺𝗽𝘂𝘁𝗶𝗻𝗴 (𝗔𝗦𝗖). The name was chosen to reflect the nationwide scope of the consortium - read the official statement here ➡️ asc.ac.at/news/2025/ne...

spent my day playing around with parallelizing an exhaustive search over a large space from a combinatorial problem in rust. 🦀 pretty solid experience, very fun! stuff that took ~3h before is now down to like 10mins. ⏱️👀

And one of these DN is ALMOA! Excited to be the coordinator of it. Looking forward to collaborating with a great consortium and training the next generation of Mathematical Optimizers! @uniklagenfurt.bsky.social #optimization #mathematics #MSCA

from the makers of evergreens like "your parcel has been deposited at a self-service station" and "nobody was at home when we tried to deliver your parcel" comes a new instant classic: "upon your request, the parcel is being held for collection." ⛽🔥🥲
