The #HPC starter pack has been used by many people new to BlueSky who want to immediately start following a decent cross-section of the HPC community

I caved in and bought an air fryer.

So far I am deeply unimpressed. Deeply!

Hoping that its because I haven’t figured out how to use it properly yet and not because it was an overrated piece of tat.

This article from The Guardian discusses many of my own concerns about AI right now:

Needed to do a computer thing so opened my notes file HowToDoThing.md it contained one line:

TODO: Write detailed notes about thing.

In what is now a solid tradition, the most important post-SC event ... publication of Glenn's SC notes!

I wrote up my notes from #SC25. Have a look: blog.glennklockwood.com/2025/12/sc25...

I’ll keep picking away at the editing, but would love to hear more from others about what stood out to them. I wasn’t at the conference itself as much this years as in the past, so I know I missed a lot.

"We were raised to believe over the decades that machines will outgrow us[, but] automatons are not consuming the globe brilliantly. They are not outsmarting us—they are overfitting on us."

Snehamol Joseph & Jeena Joseph (2025)
Digital decay: when AI eats its own homework doi.org/10.1007/s001...
Unless AI is kept in check, it will not only eat its own homework but it will also eat its legibility. We will lose the skill to distinguish a composition of a type of work, a deliberate work, against a hybrid work, a piece of work, an argument, fabricated out of past fragments. Audiences will be conditioned to believe that good enough is good enough, until even mediocrity will seem like plenty. Culture will be turned into monocropped and deprived of nutrients. The creative commons will be exhausted. And as is soil when it is overfarmed, once lost, it will not be easily recovered. Let us not flatter ourselves. It is not that AI will soon surpass us in thinking, it is more likely that it will surpass us in boring. When we leave machines to eat their own homework we are not training a generation of geniuses but beige. The cry is straight: do not confuse abundance with richness, fluency with thought, content with creation. Surprise still matters. Originality is not luxury but lifeline. Unless we defend it, we will drown in competence without creation.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

I feel these vibes very strongly. I use LLMs all the time and understand them in much more detail than most of the people who insist I should use them more!

When I point out weaknesses of the tech, I get accused of being an anti tech luddite who doesn’t get it.
jessdkant.bsky.social Jessica Kant @jessdkant.bsky.social · Oct 10
One curious thing on this site about speaking out against the encroachment of LLMs is that inevitably you get accused of being anti-tech. I don’t hate technology. I’ve used machine learning in my own code before. But I also recognize that oligarchs are so hellbent on pushing this tech for a reason.

I held a Samsung Galaxy Z Fold 7 recently and it was the first time in years that I had genuine gadget lust. I really wanted it!

I moved from android to iPhone a few years ago solely for improved battery life but this almost made me go back….almost.

In a discussion with publishers this morning, we were reminded of this Springer Nature data showing that 19% - 66% of paper authors develop new software as part of their research, where the 19% is more or less for all fields, and the 66% is for computational science.

In my day, '42' was the number we'd try to force into everything. Want to see a random number generator? '42'
Choose a number between 1 and 100? '42'

Now it seems to be 67 and I have no idea why!
