Joking, just some XSS ;)

Having fun with ;))

@AzureSupport It is not intermittent but full downtime for us!

We’re investigating an issue impacting Azure Front Door services. Customers may experience intermittent request failures or latency. Updates will be provided shortly.

@AzureSupport We are also fully down with all our CDN-hosted endpoints!! I cannot even create a support ticket as Portal is also partially down

@asmah2107 Just use Kubernetes "services", it is 2025 ;)

You've built your first microservice. Service A needs to call Service B. How does it know where Service B is? Simple. "Just put Service B's IP address in Service A's configuration file." but this is one of the most common and brittle design choice...🧵

Recently we held 2 #fsharp Meetups in Vienna, Austria, and here are the slides to them: github.com/zastrpay/meetu… F# does work ;)

@ChShersh All the 3!

After 8 months of fighting with network providers, I finally got a proper broadband at my place! 🙏 I consider dev streaming. If I were to stream, what would you like me to do? My ideas so far: 1. Teaching FP and OCaml 2. Implementing a project in OCaml 3. Review FP content

@ScottWlaschin @alexeyraga Yes, thinking about it, if I get pushed to the extreme by the auditors (will do sonarqube now for our react/typescript frontend). Our backend is 100% F# ..

@deyanp @alexeyraga I do think it would be great for someone to revive it though. A lot of enterprises have compliance rules, and if your tech (like F#) can't meet them, you can't use the tech there. 😕

Is there a static analysis tool, or an automated set of rules for F# that is focused on security? Like Sonar for C# or similar? #fsharp

@almirmesic Same here :)

5 years in with F#. Still a pure joy to write - succinct, expressive and powerful.

@mjovanovictech Totally disagree. Are you speaking from personal experience or theoretically, based on similar statements from other wise guys? Good luck creating a monolith with clean modules/good isolation, and when company grows successfully rewriting it into microservices ...

Don't start with Microservices. ❌ Even if you're confident that your application will be big enough to justify it. And here's why. 👇 Microservices come with a premium: - Team coordination - Dealing with failure - Eventual consistency - Automating deployments - Managing multiple services - Provisioning additional infrastructure You don't need this complexity at the start of a new project. Does this bring value to your users? Probably not. Your team's experience plays a significant role. If you can't manage a large monolith system, you won't do better with Microservices. Service boundaries require a lot of work to establish. How confident are you in your ability to do so from the start? Refactoring service boundaries is challenging if you make a mistake. With a Monolith, however, it is much easier. Here's a less risky strategy: - Start with a Monolith - Discover the service boundaries (Bounded contexts) - Then decide if you need to break them into Microservices Many other factors also play a role. I can't fit them all into one post. But I hope I've given you some food for thought.

@k_cieslak Saying that while we are happily developing the n-th service (n > 20) in F#, 5 years down the road with a small subset of F# features (records, DUs and functions) ;)

@k_cieslak You might be overthinking it. F# is a general-purpose language and the only thing it needed was a bit more love from MS to establish itself a bit better in the enterprise (startups wouldn't pick it anyway because of MS).

@fuglestad @AzureSupport Same for us, down again :(

@AzureSupport Azure B2C went down again..

@AzureSupport @davidjrh You have received already our subscription Id, and the subscription Ids of many other customers of yours. What is the ETA for fixing this huge issue??

@davidjrh Hi, thanks for reaching out. Would you be able to DM us with your subscription ID so we can have a better look into this? ^JP

@AzureSupport, what happened to the 99,99% SLA for AAD B2C, having in mind the current outage of it in West Europe, ongoing already for hours? You've got to have a better plan with so many nines ... #azurecloudservices

@AzureSupport You must be disconnected from the rest of your team ... simply check all the latest complaints to your @AzureSupport twitter account ...

@deyanp Hey there, if you're encountering a specific error, please send us a screenshot of the error, your subscription ID, and a timeline of when this started for you? ^GP

@ChShersh Is the resulting code simple and easy to understand by the other devs on the team?

Today I refactored some OCaml code at work using the Category Theory concept of Kan Extensions. Ngl, I felt really smart doing so. I can see the appeal now 😏

@adymitruk And there is definitely nothing in between ES and CRUD ...

The #EventSourcing struggle.

@openclue result, async, asyncResult and similar is all that we need ... I would only introduce additional if really, really needed(=rather not) ...

Custom F# computation expressions - how often do you use them and for what purpose? #fsharp
