* [Anmol Sarma](https://www.anmolsarma.in/) wrote a blog post requesting that developers "[Stop Memsettings Structures](https://www.anmolsarma.in/post/stop-struct-memset/)". This is relevant to the Project as `memset(3)` system call is often used to ensure deterministic output of packages or of binaries themselves; if the build artifacts contain the contents uninitialised memory, to ensure a reproducible build a developer would typically "zero out" the memory using `memset(3)` to ensure that it does not contain the so-called random data.

The [Go](https://golang.org) programming language has been making progress in making their builds reproducible. Ximin Luo had previously created [issue #16860](https://github.com/golang/go/issues/16860) in 2016 requesting that the compiler generates the same result regardless of the path in which the package is built. However, progress was recently made in [Change #173344](https://go-review.googlesource.com/c/go/+/173344/) (and similar) that will permit a `-trimpath` mode that will generate binaries that do not contain any local path names, similar to [`-fpath-prefix-map`](https://reproducible-builds.org/specs/build-path-prefix-map/).

In Debian, [Chris Lamb](https://chris-lamb.co.uk/) added 90 reviews of Debian packages, adding to [our knowledge about identified issues](https://tests.reproducible-builds.org/debian/index_issues.html) and 14 issues were automatically removed. Chris also added two issue types: [`build_date_in_egg_info_directory_name`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/61bf6116) & [`randomness_in_perl6_precompiled_libraries`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/b718ab29).

Cyril Brulebois then made an [upload of the `debian-installer` package](https://bugs.debian.org/920676#50) to Debian that included a number of Chris' patches and Vagrant Cascadian filed a patch to [fix the reproducibility of "u-boot" images](https://salsa.debian.org/installer-team/debian-installer/commit/deeee34bc0ee5ec879182111b809896752ad0df9) by using `-n` argument to `gzip(1)`.
