LOOPS code is still quite readable and not too dense to me.

LOOPS feels well designed and supports paradigms that still have value, such as access-oriented programming.

Object-oriented programming like it's 1986: I'm doing a fun project with LOOPS, the object extension of Interlisp.

While reading this post on what we lost with the abandonment of XML this passage caught my Lisper eye:
> XML's structure is immediately familiar. It is essentially s-expressions with angle brackets instead of parentheses. An element is a tagged list; attributes are metadata; nesting is composition.

Can you recommend modern hardware recreations (no software-only emulators) of the ZX Spectrum that are 100% compatible with the BASIC of the original 48K model and don't cost a fortune?
The devices should be fully assembled but kits or boards with no case are an option. They should also provide connections to modern displays and possibly also external keyboards.
I'm aware of these recreations:

The article is a bit thin on the technical details that matter to Firefox users seeking alternatives.
I checked out Vivaldi and I'm positive it's awesome. But I don't need fancy features as the basics browsers provide are mostly enough for me. What I want to know is how the built-in ad-blocking and privacy features of Vivaldi compare with Firefox augmented with good add-ons such as uBlock Origin and Privacy Badger.
The closed source status of Vivaldi is not necessarily an issue, but reducing the diversity of browser engined is a concern.

Multi-language IDEs that interact with interpreters via protocols are now common, from classic Emacs with its inferior process protocols to VS Code with LSP and similar modern environments.
This paper described an early exploration of these ideas: a language-independend, Interlisp-based environment that interfaced with language processors over the ARPANET. In 1974.

Immich is often called an open-source clone of Google Photos which, although accurate, doesn't convey the fundamental difference between the systems: Immich is designed with people in mind, not profit or metrics.
A revealing example of the difference is the options for searching photos not in any albums or by camera make and model (here in @npub1w56…t4ha) Google Photos users have been loudly begging for such features since day one.

☝️ To celebrate the 30th anniversary of Netscape Navigator 2.0 here is my copy I bought around 1995 when it was still a paid product. I ran the browser under Windows 95.
Shortly after snapping this photo in 2017 I tossed the product in the trash, which I regret. I took the photo as I got a sense the artifact had some historical significance, but I wasn't into retrocomputing yet and didn't realize the importance of preserving such material.

If you don't mind using Google products occasionally, the Transit option/layer of Google Maps does that. I mean clicking the Transit button on the map, not the step by step route planner.

Interlisp-D supported copy-paste between different applications, e.g. copying a bitmap or graph (lattice) and pasting it into a text or line drawing editor:
