Linux & open source

Linux and open source covers kernel releases and the projects the rest of the stack depends on, from the mailing list thread or the commit.

Linux Deleted a $10 Billion Intel Chip in One Commit. Itanium Took 23 Years to Die

Intel and HP spent roughly $10 billion building Itanium, the chip that was supposed to replace x86 forever. Analysts projected $38 billion in sales by 2001. In Linux 6.7, released in January 2024, the kernel deleted about 65,000 lines of Itanium support in one go, because nobody was left to maintain it. I went through why the most expensive bet in CPU history ended as a pile of deletions, and what it taught Linus Torvalds about anyone who promises the future needs a clean break.

AI Is Quietly Dismantling the Thing That Kept People on Windows and macOS

For 30 years the reason you could not simply switch to Linux was the software. Photoshop, Office, the apps you needed and the file formats they locked you into. In October 2026 a single developer used Claude Code to rebuild Adobe’s core creative apps in Rust and gave them away. I think the moat that protected proprietary software just sprang a leak, and the legal fight over whether that is allowed is going to be the real story.

How Intel, Microsoft, and Linux Took Down the UNIX Server Kingdoms

Going into the 1990s, a serious enterprise server meant a proprietary UNIX system running on custom RISC silicon, and it cost a fortune. By 2005 most of that market had been eaten by cheap Intel boxes running either Windows or Linux. I went back through how that happened, because it is one of the cleanest examples in computing history of a business model getting beaten on economics while its technology stayed ahead.

The 23-Year Lawsuit That Claimed to Own Part of Linux Just Died

On 10 August 2026 a US appeals court threw out the last live appeal in a legal fight that started with a forgotten 1998 UNIX project, ran through a $5 billion lawsuit, a bankruptcy, an asset sale, and a fresh filing in 2021. For 23 years a private company kept claiming it owned code sitting inside the Linux kernel. I went through the whole saga, because it is the closest the open source world ever came to a genuine extinction event, and because the thing that finally killed it was not a ruling on who was right.

Siemens Deleted a Popular Open Source Project on Its Way Out the Door, and the AGPL Made Sure That…

In October 2026, months after buying Altair for $10.6 billion, Siemens retired the OpenRadioss website and deleted its GitHub repository, pointing users to a paid product. The code was under the AGPL, so within days a Rocky Linux founder had forked it into a new project called OpenCourant. I went through what happened, why deleting the repo was the self defeating part, and what the license actually guaranteed.
