My opensource commits statistics in 2024

As today is the last day of 2024, I checked my open source commits statistics using my simple and buggy scripts. Similar statistics for 2023 is available at another post.

Note that the script may have bugs, and numbers don’t tell everything.

In short, I made 7th and 2nd biggest changes to Linux kernel memory management subsystem among the 340 people, in terms of lines of changes (2,347) and commits (102).

For the Linux kernel whole tree, the numbers become 235-th (3,754 lines) and 74th (150 commits) among 5,278 people.

I also made around 45,000 lines of changes with around 2,500 commits for non-Linux open source projects.

Linux kernel statistics

I ran my buggy script[1] to show some 2024 statistics for memory management subsystem and whole tree of Linux kernel as below.

Memory Management Subsystem

In 2024, 340 people participated in Linux kernel memory management subsystem development by making 82,650 lines of changes with 1,938 commits.

I made 7th and 2nd biggest changes among the 340 people, for lines of changes (2,347) and commits (102). Note that I counted only files under mm/ directory of the source tree, though.

Distribution of the numbers can be plotted like below.

$ ./authors.py ~/linux --commits linus/master \
        --linux_subsystems "MEMORY MANAGEMENT" \
        --since 2024-01-01 --until 2024-12-31 --skip_merge_commits \
        --sortby lines --max_nr_authors 400 --pr_for_plot | \
        ../gnuplot/plot.py --ylog --pointsize 0.3 mm-lines-per-author-2024.png

The plot for the distribution of the number of changed lines per author for memory management subsystem in 2024 is like below. Note that y-axis is in logscale. My number on the graph is 2,347.

The plot for the distribution of the number of commits per author for memory management subsystem in 2024 is like below. Note that both x-axis and y-axis are in logscale. My number on the graph is 102.

Linux kernel Whole Tree

In 2024, 5,278 people participated in Linux kernel development by making 4,598.294 lines of changes with 71,163 commits.

I made 235th and 74th biggest changes among the 5,278 people, for lines of changes (3,754) and commits (150).

The plot for the distribution of the number of changed lines per author for the whole Linux kernel source tree in 2024 is like below. Note that both x-axis and y-axis are in logscale. My number on this graph is 3,754.

Non-Linux Kernel Contributions

In 2024, I also I spend some of my time on projects other than Linux kernel including

• DAMON user-space tool (damo),
• an email tool for DAMON and Linux kernel contributors (hkml),
• my personal scripts toolbox (‘lazybox’), and
• perfbook Korean translation (https://github.com/sjp38/perfbook-ko_KR).

Let’s see simple record of my contributions on those.

Like other years, I made no small amount of changes for non-Linux projects in 2024. Around 2,500 commits of around 45,000 lines of change in total. I remind and find a few interesting points below from the numbers.

The last commit to perfbook Korean translation was February 2024, since I completed the translation of the second edition, which I started since 2021. I may do the translation from the scratch again, once the third edition is tagged. I highly recommend every programmer to read the book, since it is not only about performance and parallelism but general software engineering, in my opinion.

My last commit to lazybox was July 2024. It is a bit surprise to me, since most of my hobby programming time was spent on it for many years. I might became a boring man, or just became busy for other projects. Hopefully I will revisit it next year.

The number of changes to hkml is pretty impressive to me. I made changes for hkml even more than those for damo. I actually made an official support commitment this year, and looking forward to introduce it to more people in FOSDEM'25, to promote more DAMON contributors.
