All/most electric motors are also electric generators. Similar to how electric cars convert braking energy back to electricity.

Isn't per capita the best measure? Someone going from pure electric heating to heat pump for instance, thus reducing electricity usage for same utility, that should count as greener

Origin of Species exists, yet somehow there's the Intelligent Design community arguing that evolution is BS. How do you properly evaluate? Would you say that Origin of Species constitutes a priori proof of the concept? No, you need a l

I disagree that evolution can be "understood" by one person readily explaining it to someone else. Yes you can get a brief summary of what it is about. But you are not at all in a position to evaluate how sound it is without spend

Wait wait... appeal to the scentific community is a logical fallacy? You can say this same thing about almost any scientific finding. A less controversial example: General Relativity is extremely odd and widely accepted. If someone refuses

"Everyone knows that the earth has warmed and cooled since it existed" This is where things get wrong. Previously warming and cooling has happened over thousands of years. What we see now is something different. A couple hundred y

It is not as clear cut as that at all. Wikipedia has a page on Denial.. What is "established" is part of the debate too and obviously it is in some deniers interest to instead label themself sceptic. Apparently there has been a de

Argument against is simple: Mitigating effects climate change as you suggest will be extremely expensive. (Protecting cities from rising sea levels is really the least of problems...) If we can do something much cheaper (prevent climate cha

Saudi Arabia might have enough oil to last until demands drops..... It is also some of the cheapest oil to extract, so sometime before they might start lowering prices to push everyone else out of the market. Keep in mind their production i

by dagss 8y ago
It would be much weirder (crazy?) for Saudis to invest in oil. They have lots of fresh income when oil goes well, so the fund should be designed to do well if oil does not go well.

Does anyone know why the rotation force is not transferred mechanically to ground level?

Getting "systemic change or significant pressure" starts by individuals spreading awareness and campaigning politically, and determining what goods are produced using slave labor is a big part of that.

...that would be nice except you need to reimplement LogIf or Must again for every single function signature due to lack of metaprogramming..

Seems I misread your post. I guess I very seldom think of JSON as having anything to do with JavaScript even if that is where it originated..

by dagss 8y ago
I don't understand that argument at all. Jsonnet generates JSON. Why does it itself need to be in JSON? XSLT was brilliant except it was extremely verbose and difficult to use due to wanting to be expressed in XML. XSLT as prior art de

Well technically this is reflection which is something else than generics. You say "that's not true" but it IS true that go lack generics (or metaprogramming in general). You point out that it supports reflection which is som

If there was a 10x larger market for shipping then UPS and its competitors would have already taken it. Some things actually are zero sum games. And we are a lot closer to that now than 50 years ago when there was so much more room for grow

Has anyone worked on Lisp-like macros in Go? Executing code at compile time to emit AST and compile it.. That is what I feel is really missing. Even with strictly a compile-time phase (no run-time macro evaluation) it could be quite useful.

In that case you should likely have used fixed point arithmetic to start with. Doubles larger than 2^52 are no different from smaller numbers in context of scientific computing etc. which is what floating point is for. E.g. in a particular

Sounds like you are writing tests at the wrong level then. I was talking about a regression test for a fix for a bug found in production. For a typical backend, write such tests against the publicly exposed API. If you end up breaking tests

As long as the process had been that the only way to get a pull request for a bugfix accepted is by proving the bugfix worked with an automated regression test, then you can change the code as much as you want...

ccache is just for c/c++.. Did you consider that it could be other things with ccache that makes it slow? E.g., the need to fully expand C headers and turn it into a text stream (NOT needed for a build tool). Everything with git is lig

I've tried scons, waf, CMake, etc, always ended up hating them and return to standard Makefiles. SCons is the worst I've tried ever. As to the cost of hashing: "git status" runs on 0.009s and requires a full diff of my w

CMake generates a standard Makefile for dependency change tracking doesn't it? Just timestamp-based on hash-based?

by dagss 8y ago
I wish there was something like an updated Make, a tool that works for everything but updated to 2018. For instance Make works based on timestamps and therefore works very poorly together with git. Switch to another branch and you can get w

In many projects the database is way more important than the "backend" or what have you. Business logic in SQL (DB table schemas is 80% of business logic anyway...); Java or Python or whatever is just some glue to connect user int
