@JamesWard @grok Not familiar with those enough to really say. For functional style stuff I know f# has a lot of that built in, for non functional c# has quite a bit included and for Actors you have Orleans or @AkkaDotNET by @Aaronontheweb

Generally developers think of Java as being great for concurrency. Its not. .NET approaches are vastly superior. And even some of the best in the whole industry when you include async/await, Channels, TPL, Dataflow, ThreadPool magic, CancellationTokens.

@elonmusk I mean, you said “yeah” on another post, but it would be nice to get another more explicit answer dude. Nonetheless awesome \m/

@elonmusk Finally! But will FSD HW3 owners in Europe be offered a free upgrade to HW4? Tesla Y in particular. I couldn’t find any clarification on this. Just rumours. Cheers.

It is
Tesla Inside@TSLA_inside_
Finally. After 18 months of patience, FSD is officially approved and live in the Netherlands. I’ve been driving with it for 2 days now. And the experience is on another level. It feels like the future unfolding in real time. The precision. The intelligence. The confidence of the system. This is not incremental progress. This is a clear step forward in how mobility works. Huge thanks to Elon Musk and the entire AI team at Tesla. From a professional perspective, this shows what is possible when software, data, and real-world deployment come together at scale. The question is no longer if this will take over. The question is how fast it will expand. This is a turning point. @elonmusk

Let's face it: for such a small tool, entirely vibe-coded, there is zero advantage to using .NET.
Among the people who use coding agents as a CLI, I expect that cargo is more widely deployed than the dotnet sdk.
And people who use VS will prefer a VS extension to a console tool. x.com/nietras1/statu…

I like Copilot CLI but the billing model stresses me out a little. Because there's no hourly or daily limit, I worry that I might run out of requests before the end of the month, and use them very conservatively. Then I end the month with a lot of unused quota.
So I built a simple CLI tool to tell me how many more requests I can use for the day without worrying, along with a few additional stats.
You can install it with cargo:
cargo install copilot-usage

tldr has semantic search built in for free and the hooks pipe in the info when Claude reaches for grep
so there’s no reason to pay for something you can do natively
optionally outside of hook, gonna explore if tldr as a native mcp tool works better but that’s a test for next week

92.5% token reduction
139k → 10k tokens
$0.42 → $0.03
welcome to the game, kid
dei@parcadei
the new code intelligence layer is probably the best thing i've orchestrated to date 92% token reduction. works with any model and harness beyond excited to launch v3 and it's tooling today anthropic may have taken your OAuth but they can't take the token savings I'm giving you

Here’s a real task from my job.
I have a 100GB binary file. Produced daily. I can’t grep it. But I can decode it.
However, I can’t store the decoded version either. It’s too big.
How do I efficiently query it?
Decoding piped to grep takes 2 minutes.
I want 2 seconds.

@tmeire_ @DanielLockyer What’s stopping someone from using a protobuf transport with trpc?
English
Atlassian switched from JSON to Protobuf for one of their services, resulting in:
- 75% less memcached CPU usage
- 80% smaller data
- 33x faster deserialization
- a 55% smaller memcached cluster
English
@itsfarseen @DanielLockyer Dude you are clueless. Go and read about protobuf per example, and then include it in your “benchmark”.
English

JSON is not slow. I recently benchmarked a few binary formats in Golang along with JSON. Results: - Custom binary format, don't store field names - fastest, most compact. - Custom binary format, store field names - as fast as JSON, as big as JSON. - Gob - 2x as slow as JSON, as big as JSON. github.com/itsfarseen/bol… There is no reason for JSON to be slower than another serialization format just because it uses ASCII chars for structure and separation. Of course, you can save memory and compute by not serializing the field names, but that comes with trade offs. - Stops being self describing. - Schema needs to be managed out of band. - Harder to introspect. - Harder to debug - is it a bug in my code or is the schema out of date? JSON is the best serialization format for structured data for most use cases. Much simpler than XML, much easier to read than S-expressions.

Agent workflows shouldn’t be a black box.
KurrentDB + LangGraph =
✔️ Complete memory of every state
✔️ Queryable, replayable event streams
✔️ Integration with Jaeger + OTel tools
Better memory. Better debugging.

@swissionary @mjovanovictech The domain events are the reflection of your business logic and they are private. The integration events are the public facing events.
English
@mjovanovictech If you mix, you have to update when you change business logic even if you're just someone who wants to consume data. Entity types and events should be in separate dlls
English
Want to get started with event-driven applications?
Event notifications are one of the simplest patterns to try out.
Domain events in DDD are a great example of this pattern.
Aggregates act as a consistency boundary in a domain.
Naturally, we'll need to communicate between two aggregates at some point.
We can do this in a loosely coupled way with domain events.
An aggregate raises a domain event.
Other aggregates can subscribe to this domain event and handle it accordingly.
Here's how you could implement this with EF Core: milanjovanovic.tech/blog/how-to-us…

@yacineMTB I’ve been pretty disappointed with code on Grok and ChatGPT. What did you recommend?
English
The insane thing about the heavy weighting on coding is that it's not including cursor and API chads like myself. LLMs aren't general intelligence. They are code intelligence. That's where the demand is coming from - across the board

Big day! We’ve revealed the next major step forward in our company’s evolution: we’re rebranding from Event Store to Kurrent. We believe this new name more accurately describes our vision and mission.
I wrote a blog explaining our rationale: eventstore.com/blog/event-sto…
