I love this place. I feel so lucky to have a fully #remotework and can go for a walk to visit the castle and other amazing places nearby. No $$$ can make up for this.

It's Patch Tuesday and ASP.NET Core has a doozy, with a CVSS score of 9.9, our highest ever. Let's examine why.

The bug enables http request smuggling, which on its own for ASP.NET Core would be nowhere near that high, but that's not how we rate things...

I think my data-binding library for creating Excel spreadsheets is almost ready for a 1.0

github.com/SimonCropp/E...

Already using it in anger at work.
Spreadsheet code that would have taken a few hours to build now takes a few minutes.

In my experience: if a feature is not documented, it may as well not exist.

The corollary of this is: The cheapest way to create a feature is to add that documentation

Send me libraries that deal with network serialization 👀

We need to design a nice protocol to send/receive requests/responses/WebSocket events between processes in MSW. Looking for inspiration. Retweet appreciated!

So apparently my client has decided that we should (1) start using Cursor, and (2) show up at the office four days a week.

After more than 6 years there, I’m thinking this might be my cue to eject.

Anyone looking for a coder for a remote gig (or hybrid in Stockholm)?

ok i have smoke tested github.com/SimonCropp/D... in approx 15 solutions. seems to work ok.

i am sure there are some edge cases i have missed, and will fix them as they come up.

but i think it is good to be consumed by more than me.

Snapshot testing for Excel documents via ClosedXml

This took me way longer than expected. Mostly in the area of forcing excel documents to produce repeatable deterministic binaries over multiple test runs.

for us it is taking data from ef. so we just make the ef query map directly into the shape that the report needs. as a side effect it also avoids pulling back unnecessary data from the db
