I just shipped explicit transaction support in our MongoDB EF Core Provider.
Check out how to use it and how it differs implicit transactions (supported since 2024) and ambient transactions.

Transactions in the MongoDB EF Core Provider - DamienG
Database transactions ensure that multi-record (or in our case multi-document) operations either all succeed or all fail together.

Current A.I. is like that really helpful friend...that you just can't trust. They will always answer your question whatever it is, and usually they give accurate information. But you can never really trust them, because when they don't know, they just make stuff up. 😆

In April, I sowed some woodland wildflower seeds in a dark corner of the garden. They have been doing really well, and are now starting to bloom. Ten pounds well spent! #garden

Here's the party doing all the heavy lifting in my Baldur's Gate honour run. Magic? What's that? Pfft; we just sneak up and hit things really hard! And if that don't work, we blow them up! #bg3

We haven't been getting out enough, so yesterday we went to Cleethorpes. Lovely snowdrops in the Wolds, and then very cold on the seafront! Steels Corner House was the perfect cure for that. Then a drive by Franklin College and the Healing schools. Great mood booster! 💙

Good morning friends! Sending you all a big hug on this Friday morning. Today I will be trying to remember that even small acts of kindness and love matter—and to do a few.

Ann Patchett (author and bookstore owner at @parnassusbooks.bsky.social) recommends BEOWULF (translated by Seamus Heaney) as the book that will allow us to sleep at night and put the world into perspective.

I also found a picture of my #Amiga 500, with GVP 52MB SCSI HD and 2MB fast RAM. There is also an AT-Once board in it, so I could boot into DOS and use WordPerfect! 🤣 🤣

I found photographs that my mother took when I was a kid of my #Amiga screen with generated #Mandelbrot images. (We didn't have a printer, and certainly not a color one!) The quality isn't great, but it _is_ great to have a record of these! #Fractals
