Just for factual background, engaging data has a new infographic about California energy production that is useful [1] Worth noting that there isn't a lot of room for growth of solar that isn't battery-backed. California exports a

Subversion does not require a server :-) You can ask Subversion to create a repository anywhere you like in the filesystem.

Subversion. It was made by CVS maintainers and a lot of care and thought was put into how it works and how the commands work and what the names of the commands are. Subversion is limited in being an older model of version control where ther

The optimization mentioned in this article is to literally use memcpy for certain types. As you mention, the code is from 2005, so the options are memcpy (when applicable) or a full copy constructor. The article discusses some old-school te

Why can they call it the "American Diabetes Association" is a pretty easy question. The First Amendment. Part of the First is that the government cannot ban you from using a word unless there is a very good reason do so. "Ame

There are plenty of places that are installing nice streetlights. For example, in Berkeley when they underground utilities they install nice old-school lighting fixtures. This is very much a "these things are true and terrible" es

Sometimes a person is in the right place at the right time and has an opportunity to become rich. It's important to resist the human urge to account success as a product of one's own intelligence.

The video of the owl is a great example of doing a terrible job without the average Joe noticing. The real owl has fine light/dark concentric circles on its face. The app turned it into gray because it does not see any sign of the circ

My comment was in response to someone who was an order of magnitude off on price and time. Wasn't really meant as a review of the experience. Regarding your bad experience on the train... it seems to me that a lot of quality went downh

Your comment is entirely false. It takes just over 3 days to travel from the Bay Area to NYC. The price is $281 [1]. Now if you throw in some rooms, you are talking about first-class travel that includes all meals free. You need to consider

Yes, that annoyed me. What they really mean is that they claim this rail line will be in operation before CA High-Speed Rail. I find that hard to believe, but I would be happy to be surprised.

Ok, but folks are perfectly willing to drive to Rancho Cucamonga if it means avoiding the 200-mile long traffic jam on I-15 on Sunday afternoon. A full transit system for everyone in LA would dwarf the cost of this rail line and it would ta

The tricks in the 80s were different than today's tricks. (1) Single-pass compiler. No separate pass to convert to object or executable. (2) Written in assembler (!). Helps that Pascal has fewer dark corners. (3) No use of disk. A sing

Turbo Pascal was so fast in the 80s that if I saw a syntax error further down the page it was faster to hit "compile" and let the compiler move the cursor to the error than it was for me to move the cursor myself. It was a very sp

This seems like a rather extraordinary claim given that linguists have not even come to a consensus about American languages other than that there are dozens of language families. Seems odd to publish an extraordinary linguistic claim in th

I don't know the literal answer to your question, but I think it's hard to compare these things in a simple way because they are different kinds of damage and occur to different kinds of species. For example, wind energy in the Ba

I have no issue with experiments. But putting particulates into the air of a population center seems like a pointless risk and will generate needless controversy.

As others have mentioned, using SCCS and RCS leaves you constantly having to ask others to unlock certain files so you can have a turn editing them. Getting groups to move to CVS was hard. Devs were terrified of conflict resolution if they

Allowing plug-in hybrids to continue to be sold simply ensures that people will buy plug-in hybrids that are never plugged in and simply carry around extra weight for no useful purpose. And when those cars are passed on to the used market,

Normally modern brakes do not contain asbestos. All major car manufacturers have not used it in decades. Why was it still being used at all?

That's incorrect. The immune response is to simple fragments of the covid virus -- which is literally how all traditional vaccines work. The only difference with mRNA vaccines is that instead of giving you a single shot of virus fragme

Just to clarify a bit of confusion here ... Covid infections do not expose you to additional mRNA. The mRNA is an instruction sequence used to trick a small number of your cells into producing small virus parts for a short amount of time. F
