@nina_kali_nina You're welcome, it's an interesting corner of user interface history. I've asked to some of the original Interlisp-D developers.

@nina_kali_nina Interlisp-D has provided a hourglass pointer icon since its earliest releases betwen the late 1970s and the early 1980s. I don't know when the first Interlisp-D version came out and whether it already had the icon but the system's display facilities didn't change much since then.

The 1983 edition of the Interlisp Reference Manual mentioned the hourglass icon, see WAITINGCURSOR here:

@koen_hufkens This was indeed the case. From the latest update:

The cause for the performance degradation was identified to be unprecendented AI crawling on our servers. We have had to do more aggressive proof-of-work challenging for various expensive URLs. A novelty is that AI crawlers not only access links that are actually generated by our web frontend, but they seem to convert the URLs into a format that bypassed existing filter rules.

@koen_hufkens Possibly, given the status message:

We are currently investigating high traffic on Codeberg that has degraded the performance of our database cluster. We are still investigating. Some attempts to remediate the problem did not yield the required results.

@garthbeagle Is that Apple Bob?

@alexshendi Right, you can pass a quoted symbol to DF.

@masinter @interlisp @screwlisp

@alexshendi DF is an NLambda function, so quoting isn't needed).

@masinter @interlisp @amszmidt@mastodon.social @screwlisp

@alexshendi I get the error "Unable to load conversation 68fbc373-3980-832d-b6fd-a1a40a3a04bc".

@jackdaniel Holy sheet! 😀

@bitsplusatoms After all am is for AM. 😀

@weekend_editor I found a couple of Interlisp-D source files for color support timestamped 1986.

@symbolics

@weekend_editor What timeframe was that? Interlisp-D supported color on secondary displays no later than 1990, but probably not much earlier than a couple of years.

@symbolics

@weekend_editor That's why yours were toys.

@symbolics

@ChuckMcManis Maybe Alan Kay came close to envisioning handheld devices doing most of what PCs did. As for Gordon, his vision was remarkably deep.

@weekend_editor While you guys were playing with those toys my very first personal workstation was this.

@symbolics

@symbolics That sure qualifies.

@fluidlogic Thanks for the context, definitely a star studded cast.

@laboescapes Bene grazie.

@n1kdo Great memories.

A 1988 keynote by Gordon Bell on the history of personal workstations. The concept of personal workstation he covers is broader than machines like Suns and has deeper roots.

What's remarkable is Bell was fully aware that PCs were soon going to make workstations extinct.
