Beneath Dublin Airport lies a secret.
You may have walked through it.
You may have checked in your bags there.

But it was never meant for passengers.
It was meant for trains. 🚇

This is the 100 year story of how Dublin never got a metro:

[The Sopranos Guy™ @uncle_june]

He popularized Neo-Surrealist cinema, is what he did. He was a brave American director. And in this house, David Lynch is a hero. End of story.

@fitzr1122 I'm still around but rarely post anything 😀

[Black Lodge Cult @BlackLCult]

DAVID LYNCH has passed away. We have lost one of the greatest directors in history, a superlative artist. A unique and timeless cultural figure. Forever in our memory, forever in our hearts. Long live The Greatest.

@fitzr1122 INLAND EMPIRE tends to get some criticism but the soundtrack is up there with the others, this track in particular

[ESA Gaia @ESAGaia]

Today marks Gaia's end of observations: https://t.co/RcogUOq1o3. Gaia now performs a set of technology tests to help future missions: https://t.co/Q5HqOHa14X. The most up to date view of our Milky Way was created thanks to Gaia, with much more to come with #GaiaDR4 + #GaiaDR5.

[ESA Gaia @ESAGaia]

So long and thanks for all the fish! I just observed my last star this morning... #GaiaDPAC and @esa Gaia teams will do their best to make some great data releases from all the data I gathered! #GaiaDR4 in 2026, #GaiaDR5 around the end of the decade. Keep posted for our news items today at 10:00 CET.

With high pressure keeping most of the rain away for at least a week it is a great time for people and local authorities in Ireland to clear drains and be ready for a risk of flooding this coming winter.

[Dublin Commuters @DublinCommuters]

One of the most important things the next Government needs to prioritize is delivering new transport in Dublin.

It’s completely possible for Luas Finglas, Lucan, & the Poolbeg extension to be delivered during the next Dail, our Manifesto calls for parties to commit to it

[Ryan Abernathey @rabernat]

We just dropped something big @EarthmoverHQ - a new transactional storage engine for @zarr_dev.

[Earthmover @EarthmoverHQ]

🚀 We are thrilled to announce the release of the Icechunk storage engine, a new open-source library and specification for the storage of multidimensional array (a.k.a. tensor) data in cloud object storage.

[Derek O'Callaghan @dgocallaghan]

@FortEvilFruit @pshiroishi @mm_allora They arrived yesterday, thanks! Really enjoying the MM so far...

[Derek O'Callaghan @dgocallaghan]

@daveirl There seems to be little or no maintenance of anything nowadays. Paths becoming unusable due to weeds/grass accumulation, overhanging trees, blocked drains just waiting to flood etc.

It feels like regular maintenance that clearly used to happen has simply stopped

[Derek O'Callaghan @dgocallaghan]

Fantastic show by @JOHNMAUS in Dublin last Saturday, thanks @foggynotions

Looking forward to the new album

Hot take 🧵 on the @anacondainc academic licensing fiasco...

Anaconda provides a huge amount of value to large, well-funded academic research institutions who are absolutely fine with paying big license fees to Mathworks, Intel, etc. for software.

The @xarray_dev data model now supports vector data cubes! 🎉 Check out our blog post discussing + demonstrating this exciting development. Thank you to Xvec and others across the OS community for their work making this possible! 👏https://t.co/p5Ah8kSkx5
