This is amazing. EA1FUO has built nec2c into WebAssembly, and now you can do antenna simulations on your phone or desktop without depending on nec2c running on a server. You can also deploy it locally, and he provides instructions for how to do this on docker or bare, and you can run nec2c on the server if you like.

Takes seconds to simulate my inverted V, and it even displays updates on what it is doing while running the simulation. It then gives a 3d rendering that you can drag around to get a better intuition. As you hover your mouse over the model, it shows gain in dBi with elevation and azimuth.

Beautiful work!

I don't know where else he's active, but he's been posting about this on Reddit as he's been developing it:

I started a new chapter of my Agentic Engineering Patterns guide about anti-patterns - things NOT to do

So far I only have one: Inflicting unreviewed code on collaborators, aka dumping a thousand line PR without even making sure it works first simonwillison.net/guides/agent

The LLM revolution continues to provide perplexing trolly-problem moral quandaries, such as this thing: github.com/lombax85/clawguard

On the one hand, do I want a vibe-coded security product, whose value proposition is "alert fatigue as a service", holding root credentials to all of my critical data? Probably not. On the other hand, this project exists because the alternative is just LETTING THE LLM JUST HAVE ROOT ON EVERYTHING WITH NO OVERSIGHT. Would I rather that folks do THAT?!?!

Using AP federation to re-unify fediverse dev discussion across multiple forums

Danyl Strype @strypey@socialhub.activitypub.rocks

Continuing the discussion from Possible C2S Implementation in LAUTI:

Possible C2S Implementation in LAUTI

What is the reason that this thread does not federate? It looks like it should..

SocialHub federation has been broken for a long time, and shows no sign of being fixed. This is another reason I'm abandoning it for greener pastures. It's great that @angus is maintaining SH as a historical archive to keep the many links that point here from breaking. But it's clearly no longer the community centre it once was.

Possible C2S Implementation in LAUTI

Even though it is a medium that is not up to the task of holding a grassroots open-standards based ecosystem together, microblogging has become the preferred channel for communication in the app-centric fediverse.

I agree this is far from ideal. As I made pretty clear in my topic last year arguing against forum fragmentation. But I'm not sure that's exactly what's happening.

Some dev discussion seems to have moved to ActivityPub.space, which is a nodeBB forum, not a microposting service. Other discussions seems to be happening in communities on Lemmy services, etc. The challenge now is to realise the promise of the "threadiverse". By figuring out how to use AP federation to weave all these discussions together, so it feels like it's all happening in a unified space, and all the discussions can be discovered via any of the participating forums.
