Finding least squares solution of Ax=b?

AI Thread Summary
To find the least squares solution of Ax=b on a TI-89 graphing calculator, users should input their x values into one list and their y values into another. The process involves accessing the statistics menu, selecting the linear regression option, and executing the calculation to obtain the least squares solution. While specific commands for the TI-89 were not detailed, the approach is similar to that of the TI-84, which involves navigating to the 'stat' menu, choosing 'calc', and selecting the linear regression function. This method is useful for verifying answers to linear algebra problems.

I have a ti-84 and i am not with it right now so don't quote me on this lol but did you enter your x values into L1 and your y values into L2? on my Ti84 after that, you go to stat --> calc --> 8 (which is LinReg(a+bx)) and press enter.
 

Thread 'The Human Cost of AI'

This week, I saw a documentary done by the French called Les sacrifiés de l'IA, which was presented by a Canadian show Enquête. If you understand French I recommend it. Very eye-opening. I found a similar documentary in English called The Human Cost of AI: Data workers in the Global South. There is also an interview with Milagros Miceli (appearing in both documentaries) on Youtube: I also found a powerpoint presentation by the economist Uma Rani (appearing in the French documentary), AI...

Thread 'Cooling a processor chip'

I have been idly browsing what Apple have to offer with their new iPhone17. There is mention of 'Vapour cooling' to deal with the heat generated. Would that be the same sort of idea that was used in 'Heat Pipes' where water evaporated at the processor end and liquid water was returned from the cool end and back along a wick. At the extreme high power end, Vapour Phase Cooling has been used in multi-kW RF transmitters where (pure) water was pumped to the Anode / or alternative Collector and...
