If an organization is serious about reducing from , commensurate with IPCC pathways to stay below 1.5C, it should:

* Manage total travel budgets in terms of CO2 emissions rather than cost;

* Set a baseline budget based on current travel patterns

* Reduce the total travel budget (in CO2) by 7% each year, every year, starting immediately.

(And no futzing around with offsets)

Link rot is so very, very real.

I just visited a site that 'archives' articles from 2015. The majority of links no longer works.

What to do? You could archive pages, and link to the archived pages (I've seen many people do this). But how durable is that? Will those archival sites exist still in 10 years time?

I'm used to consult books that are centuries old. That we're unable now to archive digital stuff for longer than a couple of years is terrifying.

New blog post: The Big FIFO in the Cloud

I was recently made aware of an interesting issue, which appears to be a pretty fundamental property of the departure time-based traffic shaping that is used by BPF-based data planes, such as in the Cilium Bandwidth Manager.

It’s one of those things that seem really obvious in hindsight, but that no one thought about beforehand (apparently; or at least I didn’t). So I thought I’d write up an analysis to explain what’s going on and why it is a problem.

Disabuse yourself of the false belief that kindness is something you are, and that if you are a kind person, then kind conduct should come effortlessly to you.

Kindness is a practice that takes effort, and although it does come easier with practice, there is no way to be kind without actively doing something.

Just like a musician must move and breathe with musicality to play their instrument, so to must you move and breathe with kindness to be kind.

So anyway, if you liked my incendiary toot the other day, then you might also like the long form version.

In summary:
❎ AI isn't reliable, and even if it was
❎ AI does real harm in the real world, but even if it didn't
❎ AI hypesters are not acting in good faith, but even if they were
❎ AI can't know things or understand your complex system

Even if all that were true, making ourselves into reviewers for AI written code is still selling out ourselves and our futures

The brilliant Molly White (@molly0xfff) has given us the best coverage of the scam-ridden cryptocurrency "marketplace" -- a public service in a time when tech journalism resembles fanzines.

In a new piece, she turns her attention to deeply unattractive but central tenets of Silicon Valley's current mania, AI.

PSA: not having an IPv6 link-local address assigned on an interface breaks neighbour resolution probing, leading to subtle intermittent connectivity issues.

Don't ask me how I know this 🙈

Next years @linuxplumbersconf will be in Vienna, Austria during the Week of 16 Sep.

To quote from the private " Conference is a Wrap, see you next year" mail I just received:

""we're looking forwards to seeing you at next year's Linux Plumbers Conference (possibly even in person?) which will be in Vienna, Austria on the Week of 16 September 2024 (co-located with OSS EU). We haven't found the actual space we'll be using yet, so we don't have exact days of that week to give you.""

It's funny (not funny) how the single-digit issue numbers for any kernel driver repos stored in github/gitlab have become completely useless.

You see, a lot of bug reports and commits contain backtraces and lockdep splats. And they, in turn, contain a lot of #1 and #2 etc.

And github/gitlab think they are references to issues.

For examples, see https://github.com/intel/gvt-linux/issues/3 or https://gitlab.freedesktop.org/drm/intel/-/issues/1.

Greetings everyone ! My name is François Rincon, I am a theoretical physicist working in France at CNRS. I spent the first 20 years of my career doing research on nonlinear astrophysical fluids, plasmas and magnetic dynamics in astrophysical systems spanning many scales, ranging from the Sun, to protoplanetary accretion disks, to clusters of galaxies and the primordial […]

Dear junior to mid career technologists,

You deserve to be here, you are good enough. The imposter syndrome is normal. Try to find comfort in knowing you are not alone, we all experience imposter syndrome and for most of us it never fully goes away. I am a Distinguished Engineer at Red Hat, have over 20 years experience, a BS and MS of Computer Science, multiple patents pending, and I still have that feeling sometimes. You are not alone. You do belong. We are a community. Be kind to yourself ❤️
