Geothermal is fantastic for heating. Speaking as an Icelander, we have so much hot water in Reykjavík that we even use the residue to keep our pavements clear of ice in winter. Pipes under the sidewalks carry exiting geothermally heated water from nearby houses. It's great technology and has served us well.
"There are clever, hardworking, stupid, and lazy officers. Usually two characteristics are combined. Some are clever and hardworking; their place is the General Staff. The next ones are stupid and lazy; they make up 90 percent of every army and are suited to routine duties. Anyone who is both clever and lazy is qualified for the highest leadership duties, because he possesses the mental clarity and strength of nerve necessary for difficult decisions. One must beware of anyone who is both stupid and hardworking; he must not be entrusted with any responsibility because he will always only cause damage." -- Kurt von Hammerstein
Yes. I maintain some open source Mac apps in my spare time (and even develop new ones from time to time) using Objective-C. I've known and used this programming language for 20 years, and don't really see the point of investing in Swift given the way the Apple ecosystem has developed.
Sloth author here. To clarify, Sloth does not run with or require root privileges. However, it allows you to (optionally) run lsof itself with root privileges via Apple's Authorization framework. The application is Developer ID signed, but not notarized by Apple (which is a PITA). I guess it's "unaudited", but the source code is right there for anyone to view, analyze and build from scratch.
Also, I'd be curious to know what "blocks of code copy-pasted from stackoverflow" you found. As far as I know, I wrote all of Sloth myself, starting 19 years ago. As for references to "Mac OS X" in code comments, that seems rather pedantic given that this is very old code and Apple keeps changing the name of their operating system: Mac OS X -> OS X -> macOS.
That being said, thank you for identifying the appcast deployment script, which shouldn't have been in version control to begin with.
Dr. Strangelove : It would not be difficult, Mein Führer! Nuclear reactors could - heh, I'm sorry, Mr. President - nuclear reactors could provide power almost indefinitely. Greenhouses could maintain plant life. Animals could raised and slaughtered. A quick survey would have to be made of all the available mine sites in the country. But, I would guess, that a dwelling space for several 100,000 of our people could easily be provided.
President Merkin Muffley : Well, I would hate to have to decide who stays up and who goes down.
Dr. Strangelove : Well, that would not be necessary, Mr. President. It could easily be accomplished with a computer. And a computer could be set and programmed to accept factors of youth, health, sexual fertility, intelligence and a cross-section of necessary skills. Of course, it would be vital that top government and military men be included to foster and impart the required principles of leadership and tradition. Heil! Actually, they would breed prodigiously, yeah? There would be much time and little to do. With a proper breeding techniques and a ratio of, say, ten females to each male, I would guess that they could interact their way back to the present gross national product within, say, 20 years.
This is a very good and important point. As our technology becomes more complex and our global structures more essential, the system surely must tend towards ever greater fragility. Just like software, really.
