RISC-V and Fedora: All Aboard! (Fedora Magazine)

At least once a day I'm reminded of this slide from @bagder last year at FOSDEM

What would a TV ad promoting alternatives to driving look like? What if people who love cycling and progressive transportation reclaimed ideas like freedom, independence and even patriotism? We decided to give it a shot. Check out our new video, "America, It's Just Like Riding a Bike."

Very happy to announce my book The Linux Memory Manager is now available to pre-order at

https://nostarch.com/linux-memory-manager

It's a comprehensive 1,300 page exploration of how memory functions in Linux that goes into great depth on the subject, and is the first book of its kind for 20 years :)

Last day at #Google

In 9 years I got to:
- do bringup on Nexus and Pixel phones
- work on Tensorflow's JIT compiler targeting TPUs (XLA)
- Build the Linux kernel with Clang, LLD, and LLVM binutils
- Organize LLVM Distributor's Conf and the Toolchain track at Linux Plumbers Conf
- Keynote LLVM Dev meeting
- Hack on a new libc
- Participate in embargoed vuln remediation
- Host interns, travel

I think I was able to make and LLVM slightly better. Made great friends, too

👀 #TIL Monopoly wasn't invented by the Parker Brothers, nor the man they gave it credit for. In 1904, Monopoly was originally called The Landlord's Game, and was invented by a radical woman. Elizabeth Magie's original game had not one, but two sets of rules to choose from.
One was called "Prosperity", where every player won money anytime another gained a property. And the game was won by everyone playing only when the person with the least doubled their resources. A game of collaboration and social good.
The second set of rules was called "Monopoly", where players succeeded by taking properties and rent from those with less luck rolling the dice. The winner was the person who used their power to eliminate everyone else.
Magie's mission was to teach us how different we feel when playing Prosperity vs Monopoly, hoping that it would one day change national policies.
When the Parker Bros adopted the game, they erased the "Prosperity" rules and celebrated "Monopoly".

Seville, Spain eliminated 5,000 car parking spaces and built an 80 km protected cycling network in just 18 months with 32 million €. Result: An average 70,000 bike trips a day. Leadership.

@notjustbikes This afternoon in parliament, this research https://www.tweedekamer.nl/downloads/document?id=2024D26259 “Crashes involving heavier vehicles; Empirical relationship between vehicle weight, drivetrain and crash frequency and severity”

"In collisions between passenger cars/delivery vehicles and vulnerable road users (i.e., cyclists and pedestrians) (…) as crash opponents, the severity for the crash opponent was on average higher (…)”

Summary on page 6 and 7 is already translated into English.

Not that I'm promising anything but I've just sent the final patch to fix building #Flang on #Gentoo:

⚠️ ALL IS NOT LOST ⚠️

The news cycle is tremendously disheartening. Wildfires, the spread of climate disinformation in real time, genocides, the rise of the far right, removing fact checking and supports that protect vulnerable communities - it’s heavy.

We have a formidable amount of obstacles in our way.

But don’t lose sight of the fact that it isn’t too late.

Every fraction of action matters - and it’s not over yet.

QEMU is applying for Google Summer of Code again. Are you a QEMU contributor with a project idea you'd like to mentor this summer? Find out how to be a mentor this summer here:

This whole DeepSeek thing, even if it ends up there's some smoke and mirrors, is very indicative of a trend which I expect to dominate for many years, and that's computational efficiency. We've had years of storage is cheap, compute is cheap, just build it so it works. But now neither of those things are cheap, not at the scale we use them at. The focus is going to move back to optimization, and this is the first high profile example.

I'm heading to #FOSDEM this weekend. If you want to meet up to talk about #QEMU, #EC2, #UEFI, #KHO or any other topic I'm a useful conversation partner for, please reach out so we can find each other in the torrent of people! #fosdem2025

We will be around in @fosdem to attend a great event and meet you and maybe find next speakers for Kernel Recipes 2025.

See you there!

Kohei Tokunaga's talk on Running QEMU Inside Browser at FOSDEM '25 intrigues me. WebAssembly lacks some of the low-level primitives QEMU depends on for threading and coroutines. Getting it to work must have been challenging:

There’s a lot I disagree with Drew DeVault with, but I respect this a lot:

Cool project: "Nepenthes" is a tarpit to catch (AI) web crawlers.

"It works by generating an endless sequences of pages, each of which with dozens of links, that simply go back into a the tarpit. Pages are randomly generated, but in a deterministic way, causing them to appear to be flat files that never change. Intentional delay is added to prevent crawlers from bogging down your server, in addition to wasting their time. Lastly, optional Markov-babble can be added to the pages, to give the crawlers something to scrape up and train their LLMs on, hopefully accelerating model collapse."

When NYC started congestion pricing last week, we knew the local mainstream press would be out talking to drivers who were against the toll. So we went out and heard from some people who weren’t driving, including advocates who fought for this historic program.
