Ask HN: It's 2024. What would be your ideal blogging service?
Off the top of my head… Tools for transclusion, inserting parts of other docs and rich references to them: https://en.wikipedia.org/wiki/Transclusion i.e. I refer to lobste.rs and Hacker news stories in posts like this: https://www.oilshell.org/blog/2021/04/build-ci-comments.html I wrote a bit of (offline) JavaScript to do it, but I could see it being expanded.

Show HN: Primo – a visual CMS with Svelte blocks, a code editor, and SSG
Looks like that's using lit-html templates inside Svelte, but not any custom elements. Web components would be good because they're an interface that Primo could work with without relying on specific implementation details. They're also encapsulated with shadow DOM, and support interoperable composition (components can have child elements made from any other frameworks or library). So you could still build blocks... - Source: Hacker News / about 3 years ago
BlockSuite: An open-source Notion-like editor with multiplayer support
Any chance this might interact with Block Protocol in any way? https://blockprotocol.org/ The obvious immediate benefit to this would be native editing of Wordpress blocks for your website. But if this became standardized and usable both locally and on the web, it could open up all sorts of interesting use cases. - Source: Hacker News / about 3 years ago
A quick analogy for those still finding fediverse, lemmy, mastodon stuff confusing
I think the “servers” should be abstracted away from the user. Communities should be able to exist seamlessly across multiple servers, and the user shouldn’t need to know what servers a community is on. They should just be able to go to one website and access the entirety of the fediverse. Activities should adopt something similar to the Block protocol (https://blockprotocol.org/) so they can specify how they... Source: about 3 years ago
Are they going to keep going with Gutemberg ?
The universal block thing...that's actually not too far from what is happening. WP didn't invent blocks, they adopted the Blocks Protocol. It's slow moving, with only a couple CMS's supporting it at the moment, but Drupal, Github, and Figma are planned to implement it as well. The idea being to enable a web standard for blocks that makes then platform agnostic. Use them anywhere on the web you like. Source: about 3 years ago

AI Agentic Memory for beginners.
This is usually a challenge that any developer has to take care of when building an AI agent. In fact, managing the context is one of the hardest problems when working with AI agents and there are many companies like SuperMemory, Mem0 which have invested both resources and time to solve this problem. - Source: dev.to / 16 days ago
Best MCP Memory Servers for Teams in 2026: Context Cloud vs mem0 vs Basic Memory vs claude-mem vs MemPalace
