Here in Seattle, public school teachers would not have even the most basic cost of living adjustments without the union. And they have to bargain strenuously to get even the meager COLA they are able to get. If the unions were dissolved the

IMO this the most apt comparison with the US. Unfortunately we don't have a robust leftwing alternative. We had our Lula in the form of Sanders but we saw the DNC's response. I think if we fail to prevent fascism in this case it i

So, I guess the asymptotic behavior does matter, and what I saying was relevant?

This never made any sense to me. Why are so many programmers math phobic? You'd think an interest in math and an interest in programming would go hand in hand, especially since they aid and abet one another so beautifully. My programmi

It is? How do you know? You're saying there are no uses in statistics, data science, numerical linear algebra, etc?

Hmm, I don't buy it. The simplicity of just normalizing some Gaussian random deviates (especially since you generate them two at a time using Box-Muller) seems better than accept-reject. Especially considering that the ratio of the vol

This is totally false mathematically. Please look up the extended real number system for an example. Many branches of mathematics affix infinity to some existing number system, extending its operations consistently, and do all kinds of usef

The author is describing less a theory and more a framework or system of heuristics bases on extensive practicap experience. There's no need for rigor if it's practical and useful. I think your desire for grounding in something &q

I really like Cinnamon. Basic, basic tiling window management that covers most cases, but DE is fleshed out enough that it's actually capable of running an external monitor with my laptop's lid closed, and can even recover from th

It's a great feature, and D has a bunch of support for this kind of thing. But D and C++ have just enough differences to make extern(C++) not be automatic. It can take some pretty arcane metaprogramming to get things to work, and some

Yeah. All of this is born out of a desire to avoid meshing, for some definition of meshing. I'm on a jag that explicitly meshing or computing topology should be unnecessary for this kind of simulation. People have done contact simulati

I've got a long term project trying to see how far I can get writing a contact simulation using techniques from Klaus Hollig's book on B-spline finite element methods. I'm using D for this. I've been focusing on level se

I think we should take away people's right to live in suburbs. ;-)

Getting theoretical results along these lines that can be operationalized meaningfully is... really hard.

This is what you wrote: "Managing down isn't actually that hard to get the hang of if you have strong technical skills and reasonable communications skills. But managing down is very similar to being a good teaching professor: abs

Now this is in the US, but I've met and worked with numerous absolutely top quality teaching professors and they had a disproportionately positive impact on their students. Many of them were happy and well adjusted and did not seem in

They can also complain and make snarky comments. You don't have to read them or comment. You'll be fine if you don't.

Vast majority of this book covers DSP in very broad generality, much akin to what you would see in an undergrad EE course on the topic. Compare with Oppenheim and Schafer. Different focus but much of the same content.

Hey, I'm sorry, but such a blanket statement is pretty weak on its own. I'm interested in your perspective. Can you provide some concrete details that support your point? Because the people I know feel like AI in the classroom is

Yes... exactly my point.

Interesting thought but my impression is that the democrats are much more beholden to other forces at play in the school system. I have friends who are teachers in the public school system, have been active in the union, and are indeed agai

A calculator uses some type of finite precision arithmetic internally. If you run afoul of the limits of this arithmetic system, it may very confidently give you a wrong answer!

I think it's a great mix of features. I agree it would make sense to separate the wheat from the chaff, but if you're a mature adult, you should be able to decide which features are useful to you and figure a dialect that works. I

This is what neoliberal serfdom looks like... "60 hour weeks" until 60, unhealthy attachment to employer, using your 9 month severance as a "foundation" for the business you plan on starting... why not just retire? If th
