The author has the “problem” of knowing too much. I’ve seen this myself where presented with a Singapore Math problem solvable easily by a 3rd grader I reach for more complex algebra because “I know that’s what the problem really is” when t

What good is end to end encryption if the OS is prebuilt with a method of breaking that encryption? This is definitional backdooring, and you’re back to trusting Apple’s goodwill (and/or willingness to resist governments) to keep your

Heirloom varieties (more properly “open pollinated”) are themselves cultivars, which just means something that was selected/bred/domesticated. I think you’re trying to get at “hybrids” (which just means the breeding isn’t stable,

The materials in a solar panel are recyclable, but practically speaking it’s extremely difficult since they’re epoxied together. There’s also the issue of heavy metal content like cadmium.

Your employer analogy doesn't hold up because you have not yet tendered the services to your employer for which they would be indebted to you in the future. A better a analogy would be your mortgage, which is in fact a debt you owe in

Maybe because that commits you to a specific implementation with all of its particular choices instead of being able to compare the class of problems and solutions. Edit: Typo.

I’d bet the unsubsidized economics of residential solar for the utility actually make this likely a pretty reasonable number. I have solar myself, but we have to be honest that residential installs really destroy the economics of traditiona

> We must have wasted that safety buffer; there is no other explanation for how it disappeared. Or you just accept the research that people aren’t able to estimate time, and so it wasn’t a safety buffer on top of a real estimate so much

I don’t think the article assumes an engineer can produce reliable estimates for complex work; in fact it claims the opposite: > But the reality is that if you can make a probabalistically accurate estimate, then its likely that the task

I think adding the index to the “seven” table is probably the more meaningful change. You said the index was ignored, but based on that plan output the planner made the right choice since the filter on the “sierra_zulu” table (only one ther

It’s more nuanced than either of these ways of putting it. They lobby for specific regulation packages that work well for keeping competitors out. Regulation does set up barriers to entry, generally by definition. Needing to have lawyers

Since when has the US government felt limited by its own laws? The naïveté here is incredible. That doesn’t prove they have done it. But arguing they can’t is crazy.

The GP is saying (IIUC) that you should have 2 outlets and opposite phases. But that’s exactly what split-phase looks like in house wiring, right? (Whether that’s how the inverter functions or not).

How is what you’re proposing different than split-phase, which is already how houses are wired, and how inverters connect? This is why inverters generate 240VAC and why your electrical load panel had alternating circuits across the split ph

I’m guessing the index in question was a partial index defined with a “WHERE column NOT NULL” restriction? This was a limit of the optimizer previously (IN clauses are broken down into AND/OR groups to prove inferences but only if <
