The Haiku, Inc. financial report for 2024 is now available on the Haiku, Inc. Documents page. Our donations for 2024 were higher than any other year, breaking all previous records by almost $10,000! Even with some reasonably high expenses we still managed to have a net positive year. In 2024 our contractor waddlesplash worked the whole year, and we had a new beta release. We had some very generous large donations this year, which is part of what made this a record setting year.

[GSoC 2024]: Implementing Incremental Search [Final Report]

Blog post by calisto-mathias on Sat, 2024-08-24 01:46

Introduction The goal of this post is to document the changes I’ve successfully made during the GSoC period, the current state of the project, future enhancement goals, and a few other topics.
