By golly, I do enjoy a Halloween decoration with a message!

Bad day to launch my PHP based certificate authority

Marketing said they wanted a promotional video showing the book "in the wild". I'm assuming the Puget Sound shellfish research laboratory's beach counts as "in the wild".

Show me your Teams team group chat icon and I'll tell you how cool your team is. I go first:

When I was on Xitter, it felt like most of the value was in keeping up-to-date. On BlueSky, I feel most of the value is being reminded frequently that even though there is a lot wrong with the world, there are still many fabulous people, and always more to meet. Thank you, fabulous people.

„Was machen Sie denn mit Computern?“ „Ich habe den ‚Grund dafür‘ Algorithmus entworfen, der bei der Bahn den Verspätungen plausible Ausreden zuordnet.“ Und schon ist man der Fokus jeder Party.

I just added an experimental feature where you can compare european cloud providers next to each other: european.cloud/compare/ Beware it's fresh out of the agent - it may be glitchy here and there. Happy for feedback.

You know what’s an actual existential threat to humanity? Climate change. Weirdly, I don’t see the same people worrying about that. Odd. Wonder why that might be

AI companies in the US and China are losing $ billions per quarter with no clear path to profitability. Europe isn't losing anywhere near as much! 😱 Embarrassing! Europe must get with the program, and start throwing more of our money on the AI dumpster fire as well! We can't be out spent by the US!

Hey .NET Fans! It’s that time of year again! .NET Conf is back November 10-12, 2026. Spend three days learning from the people who build and use .NET, catching up with the community, and launching .NET 11. Learn more and save the date: msft.it/63328aPzWC #dotNETConf

Among many other things, I'm also interested in helping improve legacy code bases (C#, F#, or Haskell; possibly Python), as this is typically a really difficult problem. So get in touch if you think I can help.

I see they've named a bus stop after Gianni Infantino...

Inspired by the pancake party at @github.com, we are dropping the brand-new Studio for Oh My Posh. Studio lowers the barrier to entry for terminal theme creation so anyone can customize their setup. Explore the docs: ohmyposh.dev/docs/studio

EU rolls out a call for tenders to build up to seven AI gigafactories—Europe’s answer to the chip race, but for algorithms. The race to scale AI hardware is now officially open for bids. #AI #EU #TechPolicy #Innovation

Hey @visualstudio.com this is how devblogs.microsoft.com/visualstudio/ looks to me. The featured post is from last year. 🧐

Might I recommend putting your phone down and going outside instead of yelling at strangers on the internet? It might make you happier

We like to say that it's always a people problem, but it's not. It's a communication between people problem.

HTTP gets a QUERY method so complex searches can stop pretending to be POST

I'm reviewing my first pull request from a colleague who wrote the code AI agent assisted. Feeling burdened reviewing code that someone else generated with the help of someone else. Is this the new enterprise Ring-a-Ring o' Roses with tagging?

Dieses Social-Media-Verbot für Jugendliche erinnert mich an eine Chemiefabrik, der nicht verboten wird, ihre Abwasser in den See zu leiten, sondern stattdessen den Jugendlichen verboten wird, im See zu schwimmen.

There are steep learning curves. And there is the #kubernetes / #CNCF learning curve. 😶‍🌫️

Ich habe es mir gerade als Desktop-Hintergrund eingestellt. (Das Video dazu: www.youtube.com/watch?v=Ykb4...)

Das offizielle Teamfoto der norwegischen Nationalmannschaft. Fantastisch.

I'm going to figure out how to sneak the words "Ferto" or "Bangaranga" into my #MSBuild talk IYKYK

Which is why we should be very careful that we don't poison wells, and why "move fast and poison wells" is bad advice.

Because of challenges with budget and headcount, we figured we could get this out faster by offshoring the work to a team halfway around the world

Recently, I've been feeding LLMs photos of hand-drawn diagrams, asking them to turn them into TikZ drawings. This seems to be at the frontier of what LLMs can do. It's not an entire fiasco, but on the other hand not going particularly well, either.

You know what makes me suspicous: GitHub #Copilot has never suggested to me to restart my PC, so far.

Ich horte die Bluesky Firehose rollend für 7 Tage. Nützlich zum Beispiel, um rauszufinden, wann denn die Accounts, die dem neuen NIUS Account folgen erstellt worden sind. 402 von 471 sind jünger als 1 Tag.

A response to recent reporting in Germany, in service of clarity and accountability: First, it’s important to be precise when it comes to critical infrastructure like Signal. Signal was not “hacked” — in that our encryption, infrastructure, & the integrity of the app’s code was not compromised. 1/

Oh good grief, the embedded card generating endpoint on bluesky is called "cardyb"?

Was akzeptiert wird: Vollzeit arbeiten und immer mal fehlen aufgrund von Krankheit. Was nicht akzeptiert wird: Teilzeit arbeiten und nie krank sein.

C# 15 adds union types: closed sets of case types, exhaustive pattern matching, implicit conversions, and even support for custom non‑boxing unions. It’s a big quality‑of‑life boost for APIs that return “one of several shapes.” Full post: devblogs.microsoft.com/dotnet/cshar...

Everytime I learn more about software I am more surprised that the entire world is not on fire, all the time.

We habitually use CRUD and collection terms in our code. It's a knee-jerk decision because libraries are full of them and "go fast!" Our brains become wired to that "language." Pro Tip: Challenge your team to reject CRUD- and collection-think and seek more fitting words directly from the business.
