I created a logo for DAMON using DAMON, just for fun.

You could also create some for yourself. For detailed instructions: https://sjp38.github.io/post/damon_heatmap_logo/

ATC'24 also published two DAMON-citing papers at the same time. The first one[1] proposes a way to improve monitoring accuracy of DAMON, while the second one[2] mentions DAMON can be useful for extensible memory management (mm-ext? ;) ).

DAMO v2.4.2 [1] is out. It makes the report more holistic with hotspot functions in addition to the heatmap, wss, and memory footprints. Refer to USAGE[2] for details and an example report.

I just posted DAMON quaterly news letter for 2024-Q2.

Highlights of highlights: DAMON gained a feature for CXL-based tiered memory management. HacKerMaiL (hkml), a simple mailing tool that DAMON maintainer is developing, made an official commitment to support DAMON community.

As the DAMON maintainer and an AWS employee, I _strive_ to be the best employer of DAMON community. Assisting onboarding of new members is an important part of it.

I'm hence marking[1] 'HacKerMaiL' as a mailing tool for DAMON community that the maintainer is committed to support.

Very pleased to say that I've now finished the first draft of my book, The Linux Memory Manager.

https://linuxmemory.org/

This represents 2 years of evenings and weekends, tons of research, 99.9% from first principles and the kernel source.

There's still plenty of editing to go, but the content is written! 1,351 pages of it (!).

I am not sure on ultimate release date as it depends on how the edit goes, but we're closer now :)

As you can see from the pic, I'm very very tired but also very happy to have finished.

I think I'll chill for a while before I get back to a leisurely edit, read books, watch films, play games, spend time with my wife and cats and do a bunch of stuff the book took out of my life for a long while!

Now I'll go to bed early I think! :)
