It ends like this: all codebases become unmaintainable spaghetti after agentic AI spends years on it. Then after every agent in existence will spend minimum 24 hours reading the codebase to add a simple feature, the software is abandoned.

I code mostly in APL and J. It’s much faster to type the code than explain everything to AI.

Teaching is about moving our knowledge (the stuff we’ve collectively learned ourselves, from others and our parents [instead of everyone needing to find out on their own]) to the next generation. While some skills may become obsolete in some parts of professional life due to AI, the purpose of academia does not change much.

I think assigning coding tasks to AI is a sort of literate programming without the programming part.

My kid went to brain MRI because of migraines (standard procedure here for kids to check if there is e.g. a tumor causing the headache). I was pretty nervous due to this kind of research and the preparatory material saying that they might need to use a contrast agent. In the end they didn’t use a contrast agent and I stressed unnecessarily.

In mechanics simulations we often change the units to avoid adding small and large floats.

I am donating my other kidney to a child (1 year old with nephrosis). In any case he is living the rest of his life with this condition. I am doing this to minimize the risk of rejection during childhood. There are living people with this condition (since being babies) who are 40 years old and have families.

Great! I am also about to donate my other kidney. The difference in the long term outcome of the patient between living and dead donation is significant enough for me to go through this. My total kidney function will drop to 50% and I will be sick for 2-3 weeks but if everything goes well I will be up to 70% after few months if the remaining kidney accomodates and back to work in about 4 weeks. Of course there are some other long term risks to consider. However, I probably would not agree on this if there was an abundant supply of working pig kidneys…

Perhaps you then consider donating your kidney?

This "buffer zone" demand is much older than 30+ years. Putin wants another Molotov-Ribbentrop pact to invade his neighbors, to be called 'Putin the Conqueror'. Everything we see are his ambitions to rewrite history. He won't resort to nukes because then there is a risk of no one reading the history of the new glorious Russian empire by Putin the Conqueror, and that's against his life goals.

Take a random group of students from the general population and one of those examples (Edit: or any single given example whatsoeve). Turns out 95% are not really interested.

Edit 2: The teacher probably gave some example from biology or something that you didn't care about and therefore forgot about it.

What makes you think so? I quickly skimmed through and found nothing of the sort.

Edit: My take home message was that there is an equivalent higher order formulation which allows more structure and might be theoretically interesting. Usually higher order formulations are numerically more challenging.

I assume that the classical exposition to fluid mechanics uses newtonian concepts, mainly forces.

New comment by kyykky in "How to make your anger work for you"

It is important for the children to learn about different feelings, their control, and so on. This is not an excuse to use anger to control kids but I think you shouldn't avoid it at all costs or you will burn out or lose faith in humanity. It's not binary, angry or not angry, because there is a full range of emotions between the two end points. For example, there are few things that make me angry anymore but my older child hitting the younger one to hurt him, e.g., to revenge something trivial such as stealing a toy, which has unfortunately happened once or twice, makes my blood boil and I am happy to make it clear that there is a limit to my (and everyone else's) tolerance. As a sane person you then feel bad about losing your temper. Dealing with difficult emotions and explaining them is part of raising children.
