Not only is it too low, but it is the discontinuity in support. This leads to perverse incentives where for the wage you could make, you’d barely clear the threshold to lose benefi…

Cars do go too fast through neighborhoods: one ran into a house and killed someone inside. https://www.nbcnews.com/news/us-news/1-person-killed-tesla-a...

Things may get more expensive, but if more Americans can live a middle class life even accounting for the inflation of consumer goods I think that is a good tradeoff.

There is a joke in applied mathematics that we’re like Taco Bell. We all use the same six ingredients, mixing them in different ways. For myself, I’ve found several techniques I us…

When I was working with NREL back in 2017, they were thinking about coordinating water heater electricity use with a “smart grid.” Each device attached to the smart grid would meas…

If you want to start cutting money from the budget, cut the things that are the: defense spending. There is just so much waste defense procurement.

“Boss makes a dollar, I make a dime. That’s why I shit on company time.”

I concur. As a postdoc for many years adjacent to this work, I was similarly unimpressed. The best part about PINNs is that since there are so many parameters to tune, you can get …

I taught numerical linear algebra in grad school and was really frustrated that even the applied math department took so long to build up to solving linear systems and eigen-decomp…

“Once you have their money, you never give it back.” First Rule of Acquisition.

The first space shuttle prototype (Enterprise) started construction in 1974. The first shuttle launched in 1981. To the best of my knowledge, there were no major upgrades to the de…

It would be great if that tool existed, but it doesn’t seem to right now. I can appreciate the instinct to improve packaging, but from an occasional Python developer’s perspective …

As someone who works in numerical optimization, this is a dirty little secret of our profession. The optimization algorithms in the literature are great at finding local minima, bu…

Once I was working on a government funded small business grant trying to do something that was mathematically impossible (and literally the first example of intractability in textb…

Many of the algorithms in BLAS are not easily parallelized. For example, a QR factorization an inherently sequential algorithm. Optimizing BLAS performance comes mainly from rewrit…

But Metafilter’s fee is only one time; not annual like X is proposing.

This is a nice exposition, but it would have been more clear if they laid out the difference between inertial and gravitational masses. So far, these two varieties of mass are equi…

For reference, a typical adjunct (non tenure track instructor) will make $5000 per course per semester with no benefits. Tenured and tenure track faculty in STEM are typically paid…

I've adapted the same work flow as well. It's really nice to have one script that generates data (often taking a few minutes or hours) and then another (in TeX) that configures dis…

A good place to start might be Bret Devereaux, who regularly appears on the front page here https://acoup.blog/2022/01/14/collections-rome-decline-and-f... TL;DR it depends on what…

Only on a short term basis. As the snow is melting, this creates a large number of small, shallow ponds where mosquitoes can breed without being eaten by fish. As the year progress…

There’s plenty of precedent for corruption with respect to tax incentives, see, e.g., what Foxconn did in Wisconsin: https://www.theverge.com/21507966/foxconn-empty-factories-wi...…

...but it will almost certainly hurt the taxpayers as a whole.

I would be interested in seeing how different branding terms evolve in the literature; e.g., "machine learning" vs "artificial intelligence" vs "neural net" or "surrogate model" vs…

I'd also add C. T. Kelley's "Iterative Methods for Optimization" for more non convex theory. Nemirovski also has a variety of books and course notes that are available, but I haven…
