&lt;p&gt;Software engineering is inherently political, whether you are building capability-based microkernels, managing toxic open-source communities, or resisting corporate exploitation through unionization. True technical excellence cannot exist in a moral vacuum; the legal, social, and labor structures behind the code determine its ultimate value to society.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Porting Helios to aarch64 for my FOSDEM talk, part one&lt;/strong&gt; · Drew DeVault · &lt;a href="https://drewdevault.com/blog/Helios-aarch64/"&gt;Source&lt;/a&gt;
The author explains the process of porting the Helios microkernel, written in the Hare language, to aarch64 in order to present a slidedeck directly from a Raspberry Pi 4. The initial focus is on the bootloader, leveraging an EFI stub and device trees instead of SoC-specific complexities. A major challenge discussed is the EL2 to EL1 exception level transition on real hardware, which differed from the QEMU emulator defaults. Systems developers working on bare-metal ARM boot sequences should read this to understand practical EFI memory mapping and MMU configuration.&lt;/p&gt;</description></item></channel></rss>
