I have thoughts. Lots of thoughts. They never stop thinking. Never stop thunking.

It’s just infuriating to me that there is zero amount of money I can pay to ensure that a family member does not get scammed or victimised or otherwise taken advantage of

Every other experience in life has a “pay more for safety” option except for the ONE thing we made necessary to access life care
It is surprising to me that none of the major platforms have actual _parental control_ features so that we can limit the amount of time that our parents can spend online, and which apps they’re allowed to use. I don’t worry about my teenager’s use of the internet at all, just my octogenarian dad’s.

Can't wait for the loosened up, non-perfect, but quickly shipped AI-enhanced updates to hit my banking and insurance services next year.

Im sure there will be no issues there at all.

The two hardest problems in Computer Science are

1. Human communication

An easy way to explain this:

Which is easier to do, bake a cake from scratch, or fix a cake that someone baked after they accidentally used salt instead of sugar?
Just a thing about this: a common statement in writing is that you can fix crap, but you can't fix a blank page.

I have heard AI apologists claim that this is why it's fine to generate a first draft.

Now, to be clear, fuck this.

But also: an AI draft is a fucking blank page.
I know I don’t talk about writing much. It is because I am writing so slowly.

But I want you to know that I am taking a part of this story that absolutely sucked and took me months to produce four of the worst chapters I have ever written and in the edit I figured out how to fix it.

Happy holidays, Bluesky! I got you a megathrust earthquake, soil liquefaction, spine-tingling papers about the way our networks confound knowledge, and a PDF in a pear tree. It's my wrap on a year of trying to make sense of how we make sense of what's happening to us.

The lack of a top sheet in European bedding is just so outrageous to me. Like why?! Put a bunch of extra letters into our flavour of spelling English, sure, but no extra sheet between you and the duvet? Absolute scandalous behaviour

Cat and Ashley work so hard to do justice to both:

- the scientific rigor of their fields

- the human duties of making those fields serve us equitably, honestly, without distortion or manipulation

You have been misled about girls and math ability. Don’t miss this one:

When we say "no, everything hasn't been digitized," I need you to understand that we really mean is that virtually nothing has been digitized. This is because the realm of primary sources that historians use is incomprehensibly large.

What’s the European equivalent of this monstrous concoction that is apparently a crime against both nature and the nervous system?

For science reasons, I need this
Between this post and this review I absolutely had to try this. Tracked some down. Wish me luck

I have a whole laundry list of beloved things in this industry that are actually pretty horrific and problematic and one of these days I’m gonna feel safe enough to actually write an article detailing out that list

I just hope people can separate their identity from the beloved yet flawed ideas :(
"it seems reasonable" is the absolute curse of developer experience afaict
There's some techniques you shouldn't use that seem so reasonable! It's our responsibility to plug the ears of the next generation, lest the siren's song lead them to ruin.

Other "c'mon, it's gotta work!" techniques like SMOTE are in this class.

PLS-SEM considered harmful
Some days ago a student struggling with her master’s thesis e-mailed me, asking me about partial least squares structural equation modeling. I told her I can only tell her not to do that, and then she sent more details.>

Yay! I was so sad to see this not happening. I’m glad people have been able to take it on! Community work can be so difficult and draining without enough support. People often want to help! But making that possible is hard

It makes me overjoyed to see that the community was able to help after all ❤️

this genuinely keeps me up at night

like I don't think you go into learning science and education research as hard as I did without having this fundamental terror about how we're using humanity's potential and problem-solving

and it's REALLY HERE for me with software

For me there’s something I haven’t really seen expressed about AI that I like, and it’s where I see a ton of potential, but I do wanna clarify that I’m separating “AI” here from gen AI, the unethical issues, etc etc…

Anyways: I like the potential of ill defined and proximate program synthesis
I hear this often, but if people were trying to replace programming languages why would they be trying to generate so much programming language output though?

I think it's pretty clear that people want multiple things here
What’s really amazing about vibe-coding is how people are replacing programming languages which are strictly deterministic with human speech which is highly ambiguous and expect programming to be faster and better.

Cluster analysis for developer productivity research is like that shape sorter meme. Every fucking shape just goes in the hole that you want it to go into

Which naturally should make you suspicious that the hole implies anything about the shape (it doesn’t!)
I have been beating this dead horse re: cluster analyses & I'm back. I regret to say I just played around with creating some clusters from my own developer research but one of the charts looks ......how do I put this ....... like something that would be drawn on a teenager's desk? so I cannot share
This is from the 2025 DORA report. As ever, the report is pretty obsessed with forcing clusters to emerge. I am quite skeptical.

It’s that time of the year where Home Alone is going to be on tv a bunch. As relatives go “they should have had a battery powered alarm” and make other judgments on the family’s lack of responsibility in forgetting their kid, get a better source to learn from what happened.

Just gave my last talk of the year!

2025 was quite packed, I gave talks about:

- making rigorous causal inference more mainstream
- mediation analysis
- marginaleffects
- causal graphs (x10)

Shame on the ACM. They should know better.

In fact, here's a fun exercise to the reader: How many points from the ACM's own code of ethics does this move violate?
