the Navigating AI as an Author or Editor panelists at WorldCon

Several very different points of view on the panel. Let’s hope this stays civil.

Crystal does not yet have proper SIMD support, but this article shows how you can already use SIMD instructions with inline assembly:

Release v2.4.8 of Ktistec

Ktistec v2.4.8 has many small fixes and improvements, but includes one significant fix to ActivityPub garbage collection, which was the major feature introduced in the last release.

⚠️ Important Note: Building with Crystal Language version 1.17.x is not supported due to two breaking changes. See:

(Maybe it's three changes—compile times are also far slower and executable sizes are much larger.)

Added

  • Send "User-Agent" header identifying Ktistec on outbound HTTP requests.
  • Add accept/reject action buttons to top panel on actor pages.

Fixed

  • Add index on "username" on "actors" table. (Fixes a regression introduced in e659e84a.)
  • Rejection now correctly sets follow relationships as confirmed (previously they remained pending).
  • Fix garbage collection issues with threads created in earlier versions.

Changed

  • Prioritize the author's self-replies in thread view.

Enjoy!

Ktistec PSA

Ktistec (temporarily) only builds with versions of the Crystal Programming Language 1.16.3 and below. There was a significant change to the libxml integration in the Crystal Standard Library in version 1.17.0. Ktistec implements some extensions on top of the standard library that need to be updated as a result. A permanent fix in in progress.

upcoming plans:

i pains me to miss Gen Con this weekend, but it would be three cons in ~5 weeks!

i think my whole family may make it to dragon con this year—it started out as our annual family vacation, so it's very nice when that still works out.
