Where in the US do you live? I've lived in Florida and Chicago and every supermarket sells 100% grape juice. Costco too. Welch's and Kedem are the two big brands. There's also grape-flavored "100% juice" that's primarily apple and pear juice with grape flavoring, but the actual grape juice is on the shelf next to it.

Normally? Zero. LGA has a curfew from midnight to six AM, April 5-December 31.

In practice? It depends. Delays have a tendency to cascade in the air travel system and the Port Authority can curtail or cancel the curfew at their discretion. How frequently do exceptions to normal ops have to happen for it to be unreasonable to use "normal ops traffic" as a justification for scheduling a single controller? Ultimately, controllers have to control the traffic that they get, not the traffic that they want/expect to get, and a system that is overly optimized becomes brittle and unable to deal with exceptions to the norm.

It depends, obviously, but when installed by governments, "cost reduction" almost always takes into account labor to replace faulty lamps, which is especially relevant when there are thousands of the things out there. So governments (for the most part--there are exceptions) avoid the cheapest ones, correctly identifying them as a false economy. The cheap ones are most likely to be found in private parking lots, because parking lot owners are generally only responsible for a handful of lamps and it's a pretty minor part of their business, so they're not going to put much thought into it.

It depends strongly on implementation. LEDs can produce white light at any color temperature and CRIs ranging from terrible to great. Quality LEDs are quite nice indeed (when they're not turning purple).

Most LED streetlights replaced sodium vapor lights, though, which produce the sickliest, most horrible orange color known to humanity. Just about any LED is an improvement over those.

No, I'm objecting to what I view as a quite extreme reductionism. If the way you interpret events like the protests in LA is first to classify all people as "Democrat", "Republican", and "Other", you greatly impoverish your view of things.

Democrats? Democrats??? Like Karen Bass and Gavin Newsom are out there burning cars. Come on, man. These things are done by impulsive opportunists, not as some kind of political strategy. They happen during sports celebrations, regularly, all over the world.

The alternative minimum tax is certainly not the default for most people; you have to make quite a lot for that to be relevant. Do you mean the standard deduction?

I think things like Halstead complexity or cyclomatic complexity are more heuristic than law. To read code, the most important thing to me is the abstractions that are built, and how effectively they bury irrelevant complexities and convey important concepts.

As an example, I recently refactored some Java code that was calling a service that returned a list of Things, but it was paged: You might have to make multiple calls to the service to get all the Things back. The original code used a while loop to build a list, and later in the same function did some business logic on the Things. My refactoring actually made things more complex: I created a class called a Spliterator that iterated through each page, and when it was exhausted, called the service again to get the next one. The upside was, this allowed me to simply put the Things in a Stream<Thing> and, crucially, buried the paged nature of the request one level deeper. My reasoning is that separating an implementation detail (the request being paged) from the business logic makes the code easier to read, even if static code analysis would rate the code as slightly more complex. Also, the code that handles the pages is fairly robust and probably doesn't need to be the focus of developer attention very often, if ever, while the code that handles the business logic is much more likely to need changes from time to time.

As programmers, we have to deal with a very long chain of abstractions, from CPU instructions to network calls to high-falutin' language concepts all the way up to whatever business logic we're trying to implement. Along the way, we build our own abstractions. We have to take care that the abstractions we build benefit our future selves. Complexity measures can help measure this, but we have to remember that these measures are subordinate to the actual goal of code, which is communicating a complex series of rules and instructions to two very different audiences: The compiler/interpreter/VM/whatever, and our fellow programmers (often, our future selves who have forgotten half of the details about this code). We have to build high-quality abstractions to meet the needs of those two audiences, but static code analysis is only part of the puzzle.

> I would agree that the hierarchy thing is broadly correct, and many use this definition, but I find it unsatisfactory, as it does not move me in any way. "Yeah hierarchy is so cool man" said no one ever.

And yet, the two quotes you put forth as "psychologically correct" both use hierarchies as assumed priors. In the first, a hierarchy between "the well-turned-out and beautiful" and everyone else, and in the second, a hierarchy between "ugly deformed freaks" and "normal [people]". Do you feel that these are useful distinctions to make when setting public policy?

> Taking left-wing ideology at face value is a mistake

Taking any ideology at face value is a mistake. Words are cheap; it's easy to say one thing and do another, especially when political parties control entire media ecosystems due to the consolidation of media companies that the root comment of this thread was discussing. Is the Chinese Communist Party communist in any meaningful sense? Does it serve to weaken or reinforce hierarchies? Does it seek to empower its constituents, or consolidate power for the benefit of the few?

> How do you "make money more diffuse"?

There are tons of ways to do this, some better, some worse, and I think it's out of scope to go through them all. We do at least have a direct measurement of this one, though, called the Gini coefficient.

Broadly, left-wing politics favors making money and power more diffuse and is suspicious of hierarchy, right-wing politics favors making money and power more concentrated and embraces hierarchy. Politics is, of course, messy and not everything fits neatly into this framework (and people have idiosyncratic opinions sometimes), but that's how I view it in broad strokes. What about you?

It seems to me that your main mistake here is assuming that parties like the US Democratic Party, the UK Labour Party, the Canadian Liberal Party, etc. are left-wing. They aren't. They've been practicing "Third Way" politics for decades now, and there's very little left-wing about their proposals. IMO this is the source of a lot of public discontent with these parties: They don't offer a true alternative, just a diet version of the same policies that largely harm the public.

> Was Bill Clinton "right wing" because of his free trade politics (eg NAFTA)?

Yes! This is the point. Who benefited from Clinton's economic policies? It certainly wasn't the employees of the companies who offshored production because they were incentivized to by NAFTA. By capitulating to the right on economic issues and trying to differentiate only on the basis of social issues, the Democratic Party ceded its strongest argument: That turbo-capitalist (as you put it) economic policy only benefits corporations and the wealthy, and harms labor and the country as a whole. Democrats as a party cannot credibly make that argument anymore, because they're fully complicit. A few politicians carry lonely torches for actual left-wing politics (e.g. Bernie Sanders), but for the most part, there's close to zero power behind left wing ideas today.

Modern heat pumps can work in very cold weather, but they're much less efficient, which is reflected in their COP numbers. In my house in Chicago, we have a hybrid system--the heat pump works down to 20F or so, and we have a natural gas furnace for colder times. Natural gas is very cheap here, so this is the most cost-effective solution at the moment. I'm very eager to electrify and remove my dependence on natural gas, but I think it will be at least a few more years unless there's some breakthrough in cold-weather heat pump efficiency, or an enduring spike in natural gas prices--last time I did the math, the breakeven point for electrification here is around a COP of 4, which no heat pump can do at typical Chicago winter temperatures.

If I were building a brand new house, I probably would do it 100% electric. But most people here already have natural gas furnaces, and when they reach end-of-life they're usually replaced with another natural gas furnace. Hybrid systems like mine are catching on, but it will be a while before 100% electric is commonplace here.
