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.

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.

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. πŸ˜†

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

I'm proud to announce that today I start a new job at MongoDB as a staff engineer in the Database Experience team. Really excited to be working with a lot of great folks to make using MongoDB in your applications even better than it already is! #lifeatmongodb

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! πŸ’™

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 matterβ€”and to do a few.

The author and bookstore owner stands in front of a shelf of book holding a copy of the book BEOWULF translated by Seamus Heaney.

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! 🀣 🀣

(The ergonomics here suck, but it was the best I could do while renting a room as a neuroscience intern.)

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
