About _dps

I roam the world trying to make things better with computational mathematics. Once upon a time I taught applied math at USC.

    Russia provides something like 20% of global wheat supply, something like 15% of global agricultural supplement input, and something like 12.5% of global oil/gas. They also have an…

    You raise an important distinction, but one thing I've always found to be troublesome with K-H is that I've never seen a discussion of whether the winners would have undertaken the…

    Two likely contributors: 1) due to population effects, academic positions are much more competitive now than they were in say 1970; if you figure that the top 50 research universit…

    It was implemented by Bismarck but it was an explicit plan to outmaneuver the left wing by taking a popular part of their platform, which I've seen translated as "stealing socialis…

    As mainly a bottom-up person, I completely agree with your analysis but I wonder if you might be using "top-down architecture" here in an overloaded way? My personal style is botto…

    I think you've misunderstood what I meant; I mean incentives for businesses to pay their people more (or to offer something like apprenticeships). As for status not being lowered b…

    I worry that believing the jobs are not coming back is a self-fulfilling prophecy – one with dangerous consequences of locking its believers into perpetual dependence on supply fro…

    In the three European countries I've lived in (2 in EU + UK), licensed engineers must sign off on new building construction plans, and take responsibility for the suitability of th…

    I don't know what kind of latency vs throughput tradeoff you're facing, but given these constraints (and being on windows) I might try running multiple python processes each with t…

    I don't know if Kelley would agree with my characterization, but I don't see comptime as metaprogramming. Instead it opens the very interesting possibility of having types as value…

    This is a very large gap, but as someone who has recently had four appraisals done in the space of 6 months (long story), I have had a swing of 40% from the highest to the lowest (…

    This kind of flexibility is one of the advantages of consulting/freelancing. Obviously the career security aspect is different, but in a hot hiring market there isn't a shortage of…

    Money under the mattress does affect the economy, by changing its owner's willingness to part with a marginal dollar. If I have $1k under the mattress I probably won't risk $100 on…

    I think a very large number of people (myself included) would rather drive a 1990 Rolls Royce than a 2021 Accord, all else equal. I drove a 1990 BMW well into 2010 and I would very…

    This model circulates a lot but I haven't understood why; it literally treats them as the same thing. The model is outcome = idea x execution So both are "multipliers" in the langu…

    Unity famously hired Mike Acton (a minor hero in parts of the C++ world, and a major hero if you restrict to games). I am quite certain they pay people like him, doing infrastructu…

    I'll confess my bias up front: pairing has never worked for me, and I really just can't write serious code unless I'm in my own head. Having said that, let me now ask pairing propo…

    I like this video a lot, both because it shows the lion in peril against the pack of hyenas but also because it shows that it only takes one additional lion to change the balance c…

    I only meant to comment on the article's neutrality with regard to evaluating the meta aspect of the headline quality. I personally think that the kinds of measures proposed here a…

    Indeed this headline is editorialized against HN guidelines. The original headline is: "To Promote Equality, California Proposes a Ban on Advanced Math Classes" and it seems, at le…

    I'm with you re: "pay more if you want more applicants" but this does not sound like a situation where the jobs are economically unviable. When I was a student in LA in the mid-200…

    I share your view of what working mathematicians think like on this subject. I summarize it thus: how many interesting theorems are there in Category Theory? And the answer you get…

    In the right position, excellent SWEs have enormous leverage. A median SWE might maintain some line-of-business app for an insurance company, and an excellent one might create soft…

    I take no position on talent or wisdom, but yes the kinds of people capable of being F500 CEOs are mostly already in this category of richness.

    Many people with the skills to be CEOs of important companies would consider $1M a rounding error. It makes no difference to their economic outlook. Also, there are many ways to ma…
