At an Airbnb tonight ahead of a trip to Lapland UK tomorrow. Freezer is frozen solid (I guess that's because it's so close to Lapland!). It's listed to sleep 6. In the drawer are 3 knives, 2 spoons and 1 fork. Thankfully we are here for only 1 night.

I've been using TUnit recently for in-memory integration testing of #aspnetcore and I really like it so far. The assertion syntax takes a little getting used to but the ease of setting up dependencies such as Elasticsearch is nicely done. #dotnet

It's that time! #dotnet

First: I am really proud of this blog post title. It’s for the girlies (IYKYK). Second: .NET 10 drops tomorrow, so I did a whirlwind tour of the big and small features I worked on this cycle. Third: go read it! #dotnet #aspnetcore 📰 :https://blog.safia.rocks/2025/11/10/aspnetcore-ten/

🧵 For a side project, I've been hacking on two practical usability "features" onto top of the Activity API and #OpenTelemetry processors. I'm calling them, "rollup spans" and "conditionally suppressed child spans". 1/4

Made my first use of the new field keyword in #csharp 14 today with a lazily initialised property.

I've been having a fun little #dotnet hack to support automatically encrypting and decrypting sensitive values during serialisation using System․Text․Json. It's spiraled from a small POC to a more complex semi-real world example. I'll try to work out how to carve it up for blog and video content.

Today is a small milestone in my health management. Last home infusion with the support of a nurse. From now on, I fly solo every 3 weeks. #cvid #cvidlife #cvidawareness #commonvariableimmunedeficiency #immune #immunedeficiency #immunoglobulintherapy #ig #scig #igg #hyqvia

With the release of VS 2026 insiders, I've been trying to embrace #github #copilot agent mode. It's worked for some things but we fell out this morning! This was a simple change. I thought CoPilot might be able to save me some typing with but it took longer and more keystrokes than doing it myself!

I've been absent from social media and content creation for a bit. A few months back I got a medical diagnosis which has taken a while to digest. I have Common Variable Immunodeficiency (#CVID) which is a rare, and if untreated, potentially life-threatening chronic condition. #chronicillness (1/5)

Getting the new bits! #dotnet #visualstudio

It's already 26°C in my small home office, and the Dyson is not taking the edge off. I'll be migrating outside to the garden soon, as there's a nice breeze today.

The sun is out so I working outside in the garden this morning.

My mean time to covered in baby sick after a shower and clean T-shirt is about 2 mins!

It's been two weeks since this little lady entered our lives. We're adjusting to life as a family of four. I'm taking several weeks to enjoy the baby bubble and adapt to the lack of sleep!

The price per 100 sheets is pretty steep!

The March edition of my newsletter has just gone out. Lots of dev news items, a comic pick, and a dev tip. Sign up for a great way to keep up to date with what's going on in our industry! 😊 danclarke.beehiiv.com/p/newsletter... #programming #dotnet

Up early this morning as I was keen to get back to the ideas I had on this. Now have a working solution using TUnit as the test framework.

This evening, I've been hacking on ideas for testing #opentelemetry instrumentation for an app using the #aspnetcore WebApplicationFactory integration tests. I'm getting close with something reasonable and will write it up as a blog post once I've let the idea percolate and refined it. #dotnet

#mvpsummit FOMO for me this year due to higher priorities.

Finally cracking into one of my birthday gifts from some good friends this evening.

Good morning!

Is it just me, or is the `dotnet format` CLI command becoming an unusable mess? I'm hitting three blocking issues (on #dotnet 9, at least), so I'll have to skip using it in CI for now.

The @techorama.bsky.social NL call for papers is open! Submit your session now! sessionize.com/techorama-20...

I published the second part of my series of article about writing a .NET garbage collector in C#. This time, we build the simplest possible GC, capable of running basic .NET apps without ever freeing memory. minidump.net/writing-a-ne... #dotnet

Today is the last day of CFPs for @dddsouthwest.bsky.social's 20th anniversary conference. It is a free #softwaredevelopment conference and a great reason to visit Bristol UK this April. sessionize.com/ddd-south-we...

I just noticed that I packed my presentation clicker, but my talk at #ndclondon today has zero slides! 🤷‍♂️

It's that time of year again. #ndclondon

Day 1 on the Elastic booth at #ndclondon talking all things #elasticsearch #kibana #elk. Excited to see @stevejgordon.bsky.social's talk later. Not a bad view here either. 😊 If you're around come and say hi 👋

Later than planned, but I am on route to London ready for #ndclondon tomorrow.

TONIGHT! Doors open 5pm, Mads will take the stage at 5:30 to talk about all the awesome stuff that's coming up in C#. Venue & food provided by the awesome folks from @ndcconferences.com; there's a cash bar, we'll finish by 7pm and head to the pub. Still space to sign up if you want to come along!

I'm spending this morning rehearsing and refining my talk for #ndclondon next week. Pretty happy with it, but there's so much I want to cover, and 60 minutes goes fast. Managed to hit the time limit, but then I thought of one extra thing I wanted to show, and now working out how to squeeze that in.

I wasn't sure my recovery would allow me to get to #ndclondon next week. I'm pleased to say that I think I can do it. I'll need to manage my energy and take lots of breaks. I've been able to mostly finish prepping my talk this week and I'm excited to present it.

Thanks for all the well wishes. Antibiotics are doing their thing, and I'm slowly improving. I'm home today and back in for a few more daily doses of antibiotics. Will take a while to fully recover, but hopefully, most improvement in the next few weeks. NHS staff were great.

So 2024 was the year of shingles. 2025, it seems, is pneumonia and sepsis. Yey! I'm in the hospital and doing fine. I've been feeling rubbish for over a week and assumed it was flu. At least now I'm on IV antibiotics and in the right hands. It's not the productive start I planned for 2025!

Ring in 2025 with some OpenTelemetry love! ❤️🔭 Are you a developer using #OTel? Then take our OTel developer experience survey to let us know what you think! Your feedback helps us make improvements to the project. Survey runs through January 31st, 2025. https://buff.ly/4gyZ6VP

Finally had time over the holidays to realize a long-standing dream of mine: a hex editor that knows about the PE file and .NET metadata format. You can click any byte and it will show you which data structure it is in the tree. Every byte is covered. The parser is at github.com/KirillOsenko...

Happy New Year. May 2025 be filled with fun, happiness, and bug free code!

Woke up this morning and discovered someone had been in the house leaving stuff around, eating cookies, and drinking our milk. I'm on the phone with the police now! Merry Christmas!

My outdoor Christmas lights i bought a year and a day ago exactly have died, so the front garden looks a bit bare. Will try to resurrect them tomorrow!

I've been part of the SIG putting this together. We're keen to pinpoint some key areas for improvement of the developer experience when introducing OTel. Please share your thoughts so we can kick off 2025 with some things we can work on across #OpenTelemetry.

#Elasticsearch 8.17 has been released and here are some of my favorite features the team has delivered: the logsdb index mode, the new Elastic rerank model and full-text search support for ES|QL. ⤵️

Won another CI battle today. Slowly ticked off the things causing failures. Tests are now green!!

After an intense week of coding and CI problem solving, I'm ready for the weekend and a rest. That said, I'm off to indoor soft play with dad friends and three 2 year old tomorrow, so I'll be getting my exercise in with no real rest! Might manage a cup of coffee if the toddlers permit it! 😀

I won a week long war of attrition with CI build issues while updating our Elastic Distribution of OpenTelemetry SDK to #dotnet 9. Ended up being several small things happening coincidentally at the same time that made it painful.

I got out a "new" notepad this morning. A blast from the past! Does anyone else remember this place fondly?

Made some good progress this week on tweaks to the Elastic Transport API in support of our Ingest library work. Also hits some walls in other repositories with strange CI failures and also failed attempts to switch to the #dotnet 9 SDK requiring more investigation.

A shard is a #lucene instance that runs on a node, that's part of a cluster, and is replicated for fault tolerance. If that didn't make 100% sense - we now have a 10 minute video explaining #elastic infrastructure. (it's basically a super efficient library with librarians on roller skates?)

There's a starter pack if you are looking for the growing community of Elasticians! #Elastic #Elasticsearch #ElasticObservability go.bsky.app/6XG6iPf
