What the actual fuck is Statista doing with this graph?

My university teaches stats but not logic and honestly they could do with some jaynes
One way I am quite philosophically conservative is I do basically think that knowledge of logic (like the traditional discipline including in its modern mathematical format) makes one better at following and reconstructing ordinary language arguments, and thus should be mandatory for grad students.

I learned about Nyguist-Shannon ~1year ago and now firmly believe everyone designing time series experiments should know this. I hardly see it being discussed in transcriptomics…

The kinds of databases:

• Fancy files
• 1970s stays winning
• This would be so cool if it worked at scale
• Oh, that's why google has a monopoly on search

If ever you needed evidence of dot com 2.0
Scientists just called out Ursula von der Leyen for claiming that AI will match human reasoning by 2026. Her "evidence" consisted, it turns out, of CEO statements from OpenAI, Anthropic and Nvidia. Not research. Marketing materials. 🧵

Students should absolutely have a say in evaluating their education, but standardized forms measure overall satisfaction/mood and are not a good indicator of quality
In this commentary, I argue that student-based teaching evaluations are problematic bc

✳️ systematic biases (e.g., racism, sexism)
✳️ poor construct validity
✳️ undermine standards and learning

We should evaluate teaching as seriously as we do research. Or don't do teaching evaluations.
It is time to abandon student evaluations of teaching

A double edged sword: not patenting IP saves universities money, and open source is always a win
"Do Universities Investing In Technology Transfer Via Patenting Lose Money?"

This study reaches a conclusion I've believed to be true since seeing how tech transfer offices work. The paper calls for closing tech transfer offices and instead open sourcing all innovations.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

It seems trendy lately to have visualizations of 3D proteins structures generated by AI. These show very ugly artifacts, akin to AI pictures of humans with the wrong number of fingers. It is really not hard to make a visualization of a random protein structure using free software! #AI-slop

Grrrr. We don't call protein phosphorylation or acteylation epiproteomics. So let's not call RNA modification epitranscriptomics. In fact, realisitically, epigenetics has so many definitions, some of them non-overlapping, that this whole epi-XXXX (genetics/genomics whatever) is just not helping us.

learning from a chatbot is definitely possible (i am using it for learning) but it requires approaching it with an adversarial mindset and only works in fields where you can verify the result
You don’t “learn” from a chatbot. You consume. There’s a difference.

They’re spewing slop and people are gobbling it up (and eroding their intelligence in the process).

Misinformation is everywhere. Please don’t rely on a chatbot for anything important.

They can’t replace real human connection
