This article (which I indeed found very interesting) is part of last week’s issue of Linux Weekly News, a technical online magazine who focuses on the Linux kernel development, but also has varied content on other projects in the FLOSS ecosystem. LWN makes it content freely available to all, except for the very last issue that is “subscriber only”. There exists a mechanism, SubscriberLink, for any subscriber to let others access a not-yet-available article, that is being used for this article – it isn’t available to non-subscribers yet.

If you find this or other LWN articles interesting, I would encourage you to subscribe. There are varied subscription levels, some of which would be affordable to many (I pay $7 a month, it starts at $3.5 a month). I consider subscription as a form of donation to support a high-quality source of technical journalism – the best I personally know.

Some examples of past articles I found very interesting are:

• What’s new in TeX, part 2, by Lee Phillips, is part of a series on the current (La)TeX ecosystem
• A library for seccomp filters, by Jake Edge; more generally, LWN has been my source of information on the BPF-based “seccomp v2” revamp, conducted mostly by Will Drewry, which has been the recent change to Linux security that I found most exciting
• XDC2012: Graphics stack security, by Michael Kerrisk; security questions on X and Wayland
• Linux kernel design patterns, a fascinating series of articles by Neil Brown on the programming techniques used in the Linux kernel codebase.

So emacs unexec has been the fucking bane of OpenBSD developers for more than ten years now.
