I know each hashtag is an actor in the tags.pub design, but are there that many unique hashtags in the Fediverse (&gt; 500,000 total &#34;accounts&#34;). Is this artificially inflating the number of accounts and MAU in the FediDB statistics?

I knew there were some related git issues, but I didn&#39;t know Evan had created a document for his proposals. Based on that document, servers that don&#39;t support OAuth2 auth code grants would not be considered C2S (Social API) servers. It&#39;s interesting to me that there&#39;s no requirement for outbox POST or inbox GET. It seems like Mastodon would satisfy these C2S server requirements (OAuth2 auth code grants, bearer tokens, 429 rate limits, etc.), but that doesn&#39;t seem correct to me. 2026-06-01T08:33:09Z https://nostr.ae/nevent1qqsqnyvyaqwmyzpre5pmmk9trf8rv62vmr2n4ng0grqcvlprdpst34szyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2g7kht2 What would you consider the minimal features to be considered an #ActivityPub C2S server?

I just implemented vector search in my Mastodon instance. Now, I can search the posts in my instance (about 11 million of them) in a split second using semantic queries. It seems to work very well so far. The next step is create semantic timelines rather than relying on unreliable hashtags. 2026-03-17T06:12:00Z https://nostr.ae/nevent1qqsgd6l3ufhyucyqpkhe3c0gfmgzkh9t9y3kmkx8qntamtc6k95evaqzyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v23m532j What if... you had one Fedi account on a generic headless #ActivityPub server that simply hosts and federates your data... and had C2S UIs for microblogging, long form writing, media editing and sharing, link aggregation, games, fitness tracking, and so on, that all used that same Fedi account. Technically, it&#39;s a similar concept as ATProto (but no relay and app view) and Solid Pods (but no RDF). <br/><br/>It seems possible... if we can improve the AP C2S API/protocol sufficiently. 2026-02-24T14:56:39Z https://nostr.ae/nevent1qqsqu03dsdlkwa83lpz7jl7kn48fe555xywegmudkpv5kt9kqwl6a3gzyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2cevp0y In reply to <a href='/nevent1qqsgynajq8z0af6mdysnyszjweqkwxkavn67er26ashnlylw7rvdamqyxaxe0'>nevent1q…axe0</a><br/>_________________________<br/><br/>Vocata, ActivityPods, rdf-pub, … 2025-07-08T06:56:40Z https://nostr.ae/nevent1qqsq5gd7s22ysss9wp7matclkg92mqplgdy96ngsynju96dtwzhwdrczyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2qcgrdv In reply to <a href='/nevent1qqsrqkrkrzutwznt0q3swv88zvk7rx4964k2fdkt92td3vjnmrjdy2qu7f8zp'>nevent1q…f8zp</a><br/>_________________________<br/><br/>Those workarounds for the undermined extensibility don&#39;t negate my point and will not generally interoperate. According to the ActivityPub book, &#34;One point to note is that correctly parsing and interacting with AS2 objects with extended properties requires a JSON-LD-aware parser.&#34; I agree this isn&#39;t absolutely true (in special cases) but try sending expanded &#34;toot&#34; context term URIs and see how well it works 😉 (since all servers AFAIK expect those terms to be compacted). 2025-07-06T13:27:14Z https://nostr.ae/nevent1qqsye5g0nh430mg4kaj4hke9h4pkvr9nyeg4chkqng5u4xxekr0nwvszyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2hdqmt5 To follow up on my #ActivityPub C2S post from a few days ago, I wrote a blog article on my thoughts about improving the C2S protocol and a description of some related experimentation I&#39;ve been doing.<br/><a href="https://www.stevebate.net/activitypub-client-api-a-way-forward/">https://www.stevebate.net/activitypub-client-api-a-way-forward/</a> 2025-07-06T12:02:57Z https://nostr.ae/nevent1qqstrleqqy95mg9320ynsq9qvdrac0rzaa9ngzuw88rdx8cu0t6vsygzyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v25r9vz6 Just for fun... try this #ActivityPub quiz to test your knowledge of the protocol.<br/><br/><a href="https://apquiz.stevebate.dev/">https://apquiz.stevebate.dev/</a> 2025-05-11T07:18:31Z https://nostr.ae/nevent1qqs00r09lt7ktz00qjyzs4ve7c45u9garknuslalmjzsde6hfu4hpvszyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2gs5taw In reply to <a href='/nevent1qqsrp2pe6la3jzcfwngs4u275yy2t567vl2qrxjj4h4y7c0lfqnv77gj7u0z7'>nevent1q…u0z7</a><br/>_________________________<br/><br/>Announcing Jaseur, an #ActivityPub server in C++, written by AI agents.

One autoresponder will use a local LLM (ollama) to generate responses to direct messages. Overall, the experiment has been useful. The code is not the greatest, but it works, which really surprises me. However, I&#39;m seeing the agent having more issues as the complexity of the code increases.

Having the AI write unit tests has been key because it often creates regressions when adding features. The agents do a surprisingly good job of diagnosing compiler and unit test failures and fixing the problem automatically. 2025-03-17T16:04:13Z https://nostr.ae/nevent1qqspnkgsqpj4pwlwj2x03jrug6l62dugaxd3wfuaqukjgmyldfqynmszyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v224yvnc I&#39;ve been playing with the experimental GitHub Copilot agent mode in vscode. I&#39;ve asked it to start from an empty directory and create an #ActivityPub server in C++, directed only by prompts (no human coding). So far, it has created a C++ project and implemented WebFinger, resource persistence, resource retrieval and a decent set of unit tests. At this point, Mastodon is able to discover our actors. The AI is currently implementing Follow processing. I&#39;m curious to learn how far I can push this. 2025-03-15T15:46:15Z https://nostr.ae/nevent1qqsttdfympahxmcd34k0e3mdv94te7kjucjtsyv02zsgufnq054cxhgzyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2qxt268 I dream of the day when I&#39;m not forced to choose between decentralization and a good user (or developer) experience. #ActivityPub (P.S. if there are replies to this post, you probably won&#39;t see most of them on your instance.) 2025-01-18T08:05:53Z https://nostr.ae/nevent1qqs2s0hhw8tytaz5ady9372rpwxpn54pugu9nfjy0xkxe9r9m7r66qczyqyh7exhr57jpk5sqgn7wjg3xgnt4spvwzglmt4ryxjdtgyv8f0v2exkzpu The &#34;Social Web&#34; (#ActivityPub) Foundation&#39;s support from Meta and their links to Meta and X are even more dubious after Zuck&#39;s policy announcement.
