marius

Mostly a programmer.

Implementing #ActivityPub in the #Go programming language.

Current projects:

* #GoActivityPub - a library to use ActivityPub in Go.

* #FedBOX - a generic ActivityPub service supporting the client to server API.

* #brutalinks - a link aggregator inspired by (old) reddit, hacker news and lobste.rs built on top of FedBOX.

* #oni - a single user ActivityPub server with minimal fuss.

My posts are mostly related to ActivityPub and web development.

I'm not sure which instance you mean, these two actors are different.
@nprofile…n04x
@nprofile…t476
The first one is on an instance that should have RFC9421 enabled, but the second isn't.
I enabled request debug on it, if you want to try again.

@nprofile…3ftj on the other hand Sailfish OS is a full blown linux distribution. I am not knowledgeable enough to know if it also relies on android for the hardware access drivers (as it does for the Xperia models they support) but maybe Jolla did some underground work to have linux native drivers for it.

@nprofile…9kds the one bitter tasting pill I got from Drew's writing is that he's seemingly unable to accept that perhaps he interacted with people during their "asshole" phase of their lives and that others can change and grow too. Perhaps he needs them to write a mea-culpa blog post, who knows. I've seen him at the forefront of at least two vilification campaigns at least in the past couple of years... and that feels somewhat hypocritical...

2026-03-31 15:42:18 UTC

@nprofile…nptm does Mitra handle this kind of Image object?
I forgot how complicated the structure gets: https://marius.federated.id/uploads/storage-pg-almost-done
(Basically the client I create these with generates web-optimized versions, uploads them, and then aggregates them into this final Image. Individually they are also valid Image objects.)

@nprofile…nptm lol, based on the "claims" at the begining, why do I feel like the "thanks" at the end should be in quotations?
Also I take umbrage with calling what I've been doing for the past 8 years as "being not difficult to build nor an interesting concept". I feel like, you and other developers having the benefit of dynamically typed programming languages, underestimate how that can be worked into robust APIs when you're limited by less versatile stacks.

@nprofile…nptm I see, then yes, after=URL and before=URL and then maxItems=XXX to govern the amount of items on a page.
The FEP is about using the ActivityPub object keys as a query parameters to filter, but After/MaxItems/Before are an implementation detail of GoActivityPub.
I treat them as opaque elements of the IDs corresponding to the next/previous/first properties of collections.

2026-02-21 19:03:10 UTC

- reply

@nprofile…nptm the collections have a next property which consumers should follow, no need to mess with the individual query parameters.

@nprofile…f3zv personally I was also irked a little about the fact that Meredith chooses to side-step completely any mention of alternatives to the mainstream OS choices, and alternatives to mainstream cloud providers.
I'm not sure if they have blinders on, or there's some deeper conflict of interests there, but it's definitely a discourse that is serving to gaslight Signal users.

@nprofile…f3zv something similar to the zoom pan effect Mastodon has on images. I was thinking I was going to be cleverer and use drag and drop to keep track of the mouse movement, but that is where it fails for me. :D

@nprofile…f3zv sure, sure, I'm trying to use it for a somewhat unorthodox purpose which is not to drag and drop. :D

2025-10-17 16:53:24 UTC

Well, it looks like the drag and drop Web API is f*ed up beyond any recognition, and can't be reliably used for cross browser stuff.

@nprofile…84gr people trying to shame framework the company for sponsoring Hyperland and Omarchy, which have maintainers that are bad people according to the internet. (Again, I am not trying to debate this, but I am not ready to state it as fact until I see them personally actually being bad people, which is probably won't happen as I'm not interested one bit in reading their opinions on anything really. PS. I hate adding disclaimers upon disclaimers, but I feel like good faith discussions about this subject are hard to come by, and I feel the need to preemptively clarify what I am and what I am not saying.)

2025-10-14 08:09:57 UTC

- reply

@nprofile…84gr I think the main distinction is that originally it was about giving access to as many people as possible to high quality software, and today is about denying that access (to create, use or get funds) to the "bad" people. Personally I think the later is tilting at windmills. And mind you I'm not trying to debate "if" or "how" bad these people are.

@nprofile…vax5 I suspect that the thing that's preventing you from doing that in the fediverse is not ActivityPub itself, but how Mastodon compatible servers decided to use web finger - which is a completely separate discovery mechanism anyway.
A bit of a pointless exercise but you can find my blog using webfinger like this: https://marius.federated.id/.well-known/webfinger?resource=https://marius.federated.id

@nprofile…0tle if the perspective is that Mastodon is doing a poor job as a platform leader, then yes, it does.
They captured so much interest and capital in the past 5 years and they chose to completely ignore proper ActivityPub spec conformance in favour of things like arguing about quote posting. Sigh...

For such a young project it is able to do quite a lot, including CSS and inline images.

It is now available on the first run and every modification can be done afterwards using client to server #ActivityPub calls. Yay!

@nprofile…t9gy jitter is when you add/subtract some value from a computed value to provide some obfuscation.
In this case @nprofile…7nc8 is probably thinking about masking the exact location of a potential user by converting it to an area with a random radius, but I might be wrong. So you'd know that there are other users "in vicinity" but not their pin-point precision location.

@nprofile…3w02 personally personally I think telling a huge chunk of the Romanian voters that their vote doesn't matter if it's for the "wrong" candidate is not the right way to conduct democracy. We (but especially the politicians) need to empathise with the people that do not feel represented by anyone else except the crazy anti-system candidate instead of pissing on their choice.

@nprofile…3w02 no I do not think that at all. Maybe he didn't know the extent of the operation, but most likely he was aware something was planned. However, knowing it or proving it are very different things.

> everything Georgescu and Russians did
@nprofile…3w02 I think you should stop assuming things. Georgescu is not proven to have done anything except being a right-winger, messianic asshole. Things being done on his behalf does not make him directly involved. Nuance is important.

@nprofile…27xz I think the only reference in the aggregated ActivityX specifications is that attributedTo has "Range: Object | Link".
Which one do you consider "acct:..." would qualify as?
My opinion is none. Webfinger resources are not a compatible method of directly referencing objects in the fediverse.

@nprofile…s5e3 if I understand correctly what you want to do, I think the idiomatic solution would be to write your own http.RoundTripper implementation which does only what you need, and delegates to the previous Transport for the common http parts.
