  • I suppose it depends on the language? For the most part I think you’re right. Exceptions are only used (if at all) in situations where a program diverges unexpectedly from its normal flow. But take a language like Python. They’re just everywhere. Even your plain old for loop ends on an exception, and that’s just business as usual.

    But the mining, milling, and production of nuclear fuel, as well as the construction and decommissioning of nuclear plants, emit greenhouse gases at levels ranging from 10 to 130 grams of carbon dioxide per kilowatt hour of power — lower than fossil fuels but higher than wind and hydroelectricity (and roughly on par with solar).

    That’s interesting. The article they link gives a bit more detail:

    These energy intensities translate into greenhouse gas intensities for LWR and HWR of between 10 and 130 g CO2-e/kWhel, with an average of 65 g CO2-e/kWhel.

    While these greenhouse gases are expectedly lower than those of fossil technologies (typically 600–1200 g CO2-e/kWhel), they are higher than reported figures for wind turbines and hydroelectricity (around 15–25 g CO2-e/kWhel) and in the order of, or slightly lower than, solar photovoltaic or solar thermal power (around 90 g CO2-e/kWhel).

    The wide range for nuclear apparently comes from difficulties in estimating the carbon footprint of mining/processing the uranium, but that nuclear is sort of in the middle of the pack in carbon footprint relative to renewables in spite of the fueling costs is good to know.

    I suppose these sort of numbers may change dramatically in years to come. Take solar. A lot of focus seems to be on the efficiency of panels, which would almost certainly lower the carbon cost per unit of energy as it improves, but a breakthrough in panel longevity would also do that in an amortized emissions sort of way.


  • I guess the central premise of capitalism is that while every society has its haves and have nots, capitalism is supposed to encourage the haves to invest in the economy rather than hoarding their wealth. In return, they stand to get even wealthier, but a stronger economy ought to generate more employment and generally improve the lives of commoners as well.

    Unfortunately, in a never-ending quest to make wealth-generation more efficient and streamlined, employment is being eliminated through automation, outsourcing, etc. and the system is eating itself out from the inside. I doubt it can persist much longer, but what will replace it remains unclear. I pray that it will be something sensible that ensures everyone has their basic needs met and can still find rewarding pursuits in life. But there are so many ways it could go very wrong, and that includes staying on the current course.





  • Any New Yorkers here? I’m interested in your perspective on Giuliani. I only have a cursory knowledge of him. He first came to my attention when he made headlines busting some crime family as a DA way back when. Then he was in the news a lot as the mayor of NYC during 9/11. He seemed pretty respected at the time? I dunno. And next thing you know, he resurfaces as an enforcer for the Trump administration, winding up getting disbarred and generally shunned by society. I guess I’m curious as to whether he was always a scumbag or grew into the role?








  • I’ve actually been having more trouble with Apple Maps lately.

    My last trip was to perform at a country fair type thing and it couldn’t locate the venue. So I thought maybe if I put on the satellite view, I could spot it and drop a pin? But the whole area was behind a cloud. Wow.

    Then later, when we were returning, it tried to send me on a shortcut through a mall parking into an overgrown field.
