fluorinerocket··on The collapse of the econ PhD job market
It's fine to want to solve interesting math problems for the sake of it I suppose but they shouldn't be so certain about things when telling politicians what policies will work

but is it element by element multiplication, or matrix multiplication? I honestly just prefer calling matmul.

Let me guess, they are calling landlines. And no one picks up unknown numbers on cell phones. They are hopelessly behind the times

fluorinerocket··on A simple way to generate random points on a sphere
What about generating 4 random numbers, each uniformly distributed. Make it a vector and normalize it. Now use it as a quaternion rotation, apply it to to vector (1,0,0)

I was constantly chided as well, The teachers seem to have regarded my poor handwriting as moral failure,ike choosing to do something naughty, rather than as something that they needed to give me more tutoring on.

fluorinerocket··on How Boom uses software to accelerate hardware development
In MDAO you definitely know all the constraints at compile time, but inequality constraints can be active or inactive as the optimizer progresses.

That's how SNOPT, IPOPT, presumably KNITRO and nonlinear programming optimizers work.

Yes MDAO is "just" constrained nonlinear optimization.

You come up with a model for your thing, which often involves multiple "disciplines" like mass, propulsion, aerodynamics, loads, trajectory/equations of motion, and then usually use some framework to calculate the constraints values and objective value and their gradients

Yes, direct immersion cooling coupled with an organic rankine cycle could do this. But you won't recover much electricity because of the relatively low temperature of the heat source- 60 to 70 deg c dielectric fluid.

fluorinerocket··on The FPGA turns 40
National Instruments made programming FPGAs accessible to engineers who are not EEs like me via LabVIEW. It was really cool to have loops running at tens of kHz up to 100MHz speeds

It's really too bad that it was locked to NI products and they've kind faded away.

I sometimes like to think of what could have been, if the ability to program FPGAs so easily would have become more popular.

A lottery ticket is legal but expected value is negative. Same with casino games. Sure it's legal and sometimes people win but in my book it's a scam, even if not technically one.

What I particularly resent is the pretence from companies that a lower salary can be compensated by options. Such BS

fluorinerocket··on Startup Equity 101
I've concluded that options are a scam after owning them in many companies. It's never amounted to anything
fluorinerocket··on Grid-Free Approach to Partial Differential Equations on Volumetric Domains [pdf]
What I'm interested in seeing if this could be used for multidisciplinary design optimization. Currently it is possible to do coupled aero structural optimization of wings and the like but of course you have to deal with all the mesh stuff and make it deformable as wing changes shape. And then get the gradients out.

Very curious to see if it might be possible to greatly simplify the problem with this method
