This one hurts. I've really enjoyed Tim's work in the past But let's just be totally bloody clear here: every single person using a text fabrication engine to replace their work, research and writing skills: THIS MOMENT IS COMING FOR YOU TOO It is truly just a matter of time. It's inevitable ⏱️

I recently wrote a piece critical of Matt Chun's essay about the shootings at Bondi Beach. In it, I attributed a quote to him that were not his words. This was an egregious mistake and I apologise unreservedly. At his request, I have removed the piece, but I wanted to make sure everyone here was aware of the error. I really have no excuse other than my own carelessness and a degree of hubris. I used AI to search for other examples Of how people had responded to Chun's piece, asking for links and key quotes. It brought up mainly mainstream pieces from Australia but some Reddit links, and links from overseas sources. I also asked it to summarise the piece, not in lieu of reading it but in addition. (I had first read it after reading Guy Rundle's comments about it.) I clicked through on some of the links. I noted down the quote, wrote a drop in paragraph using it, and added it to the draft at some point. That I didn't double-check it or recognise it as not part of the original essay is entirely on me. So, yes, this is a case Of AI generating a false quote, but the issue is that I should've been far more careful in checking it and I am deeply sorry, and embarrassed, that I didn't do it to the extent necessary. Obviously, we are all aware of this issue of falseSo, yes, this is a case of AI generating a false quote, but the issue is that I should've been far more careful in checking it and I am deeply sorry, and embarrassed, that I didn't do it to the extent necessary. Obviously, we are all aware of this issue of false quotes and attributions with AI, but I had enough hubris to think such a thing would never get past me. It did. When Matt Chun first contacted me, I initially responded by saying "It came from a email discussion with people I know and generally trust and I should've been much more careful." I was pretty sure I knew what the issue was, but this was a fob to give me time to think about it. Obviously, I should've just said, let me look into it, but I actually thought that sounded worse, more like a fob than the false reason I gave. That's not an excuse, just the thought process in the moment. I also apologise for this. I will leave further discussion of the the problems with using AI in this way for later. For now, I really want to make clear the error and to apologise publicly to Matt Chun for the false quote and the initially misleading response. As I say, I have no excuse beyond my own carelessness and hubris. B 987x686px, WMatt Chun Subscribe @mattchun Update: After initially lying to me about the source Of the misattribution, Tim Dunlop has now admitted that he used Al to write his article, which generated the entirely false paragraph attributed to me as a 'quote'. The false 'quote' is central to Dunlop's article, and essential to his criticism of me. It's the basis from which he develops a number of defamatory imputations, and from which he invites his readership to conclude that I am frankly, grotesque'. Dunlop has now removed the article and has posted a public apology. However, the article was published for 30 days, during which time it enjoyed wide engagement and shares. It drew a significant number of comments by admiring readers who found his misinformation convincing. The article also remains in the inboxes of his many subscribers. It appears that Dunlop is a journalist for national mastheads, a published author, and a •sought-after' public speaker with a PhD in 'political philosophy and communication'. He has a large audience including hundreds of paid subscribers, and is currently '#45 rising in world politics' on this platform. @ May 26 Matt Chun I did not say the words •quoted' below. I've never seen these words before. and they certainly don't appear in my writing as Tim Dunlop claims. Nevertheless, Dunlop develops a critique of me based on this complete misattribution. In the comments section of his article, Dunlop is congratulated as •clear-sighted and thoroughly informed'.

My desktop PC is 5 years old and showing its age. What do you suggest I look at for a new machine for scientific computing? The current specs are - Intel i7-11700 with 32GB RAM - NVIDIA RTX 3070 GPU - 1TB SSD + 1TB HDD disk space

In what is now a solid tradition, the most important post-SC event ... publication of Glenn's SC notes! #HPC #SC25 #supercomputing #HPCignites

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. #HPC
