I could never justify the time investment to upstream a lot of my python-build-standalone work. I made some attempts. But it always felt like I was swimming against a heavy current and the talk to meaningful action ratio was too high. The p

Some of Apple's code signing is open source (mostly in SecurityFramework). But not enough is open source to be able to build a modern `codesign`. The source you linked is ~10 years old and woefully out of date, for example! I don'

Note that gon is a glorified front-end for executing processes like `codesign`, `altool`, and even `ditto` for zip file generation. This Rust implementation, by contrast, has all the functionality implemented in pure Rust: there is no calli

XAR signing is effectively just an RFC 5652 CMS signature plus some minimal data structure manipulation. Code at https://github.com/indygreg/PyOxidizer/blob/faa7dfcea5d66bf5... . Mach-O and bundles, by contras

rcodesign can sign and notarize applications written in any language. From rcodesign's perspective, Rust is an implementation detail of the tool itself.

While this IFUNC feature does exist and it is useful, when I performed binary analysis on every package in Ubuntu in January, I found that only ~11 distinct packages have IFUNCs. It certainly looks like this ELF feature is not really used m

The index is a power user feature. Its forced presence in Git effectively constitutes a usability barrier for new users. After all, a VCS is effectively a glorified abstraction for "save a file." Any barrier imposed between changi

I once helped maintain a nearly full featured implementation of make in Python (pymake) that grew out of the Firefox project. As much as I would like to support efforts like this, I feel like it is ultimately doomed to suffer from usability

I removed the background image and made the text blacker. Might take a force refresh to pick up the CSS file change. Is it good enough or are further tweaks needed? If more, my web design skills are mediocre, so actionable feedback would be

I converted PyOxidizer's configuration files from TOML to Starlark because I found it effectively impossible to express complex primitives in a static configuration file and the static nature was constraining end-user utility. A common

The criticisms about musl's memory allocator being slower than glibc may be true. However, this specific issue can be resolved by telling the Python interpreter to use e.g. jemalloc as its allocator instead of the system allocator. Unf

The late start was mostly due to having to retain Python 2.4/2.5 compatibility until May 2015 and it was literally impossible to use some future statements or some Python 3 syntax until 2.6 was required. I have updated the post to refl

Obviously not applicable to Linux since it is hosted on Git, but Mercurial has this "clone bundles" feature built in. If you e.g. `hg clone https://hg.mozilla.org/mozilla-central` to clone the main Firefox repo, y

I'm totally OK with Python's threading choice of saying only 1 Python thread may execute Python code at any time. This is a totally reasonable choice and avoids a lot of complexity with multithreaded programming. If that's ho

I wrote the linked post and maintain the Firefox build system. The reason is that in 2018 (and for the past 10 years honestly) and it is far easier to find people who know Python than Perl. Python is essentially the lingua franca in Firefox

Git is actively rewriting many of their shell and Perl code in C. Performance and portability are given as reasons (having shell and Perl as a dependency on Windows is a bit of a kludge). And shell scripts are much slower on Windows because
