Lots of them. A few hundreds, I think. Viability may depend on site. But if there's space nearby for a reasonable array, there doesn't seem to be any reason not to use it no matter how small it gets (any size will result in sa

Technically, it's primarily a DC source. Batteries are a DC sink. It actually seems to make a lot of sense to charge the latter from the former.

Which is quite an incentive to save on electricity as much as you can, I'd think.

But Java conceptually has a lot of drawbacks that require the JVM to have screaming performance to compensate for. Almost everything being a "headered" object being probably the worst offender. Even a slightly worse Go compiler

The problem is that software works the same every time, hardware doesn't have to (for example, if there was some kind of wear in the umbilical, for example).

Lots of interesting things to read, thank you! (To the others as well.)

In my home, a single Powerwall battery could cover 90+ percent (or perhaps 95+ percent?) of nights even in an off-grid arrangement. Covering the rare extremes with a $150 generator would be more cost-efficient than using a larger battery, a

I'm wondering if torrents as such are actually useful for this. I'd figure some kind of virtual file system (perhaps based on BitTorrent) would be very useful. You'd simply pass a file path to an open() routine in your scie

I never understood Excel or any other spreadsheet's database features (as in "why such a convoluted thing?") but we did have set theory in high school. There must be better environments for such data processing tasks. If

Well it's certainly better than what they were doing before, trying to look like the iAPX 432 with their memory segments and all that stuff.

I suspect that Oberon wants you to roll out your own text library. It's actually how C probably wants you to roll out your own string library, too, because "C strings" are no better than Oberon's text facilities. The pro

Just compare the price of a solar panel with the price of coal you'd have to pay for in China. That's the uppermost possible limit of what you could expect for CO₂ emissions if you didn't have to pay for anything else. Just

Even in a 100%-coal grid, I don't think it's likely that >1000 kg CO₂/kWp is necessary. German manufacturers can achieve 400 kg CO₂/kWp in the still-rather-mediocre German grid.

140 W is probably not the cheapest-per-watt panel format. Why don't you visit Germany with a van?

by jakub_h 10y ago
In the US, I'd image tariffs on panels having a much lower influence then elsewhere in the world. Even if panels were completely free in the US, a US-based residential solar system is going to be more expensive to install than even Eur

Or, solar+battery+generator for uninterruped power while still keeping costs low compared to a large battery?

Proper passive house design in the future should ameliorate temperature issues, both in terms of heating and cooling.

Yes, but it was defined after actual assembly/low level languages like BLISS. So it was defined as a way of doing something "assembly-like" (or BLISS-like, or BCPL-like) in an environment that didn't allow for such cod

I'm not sure "serendipity" is quite the proper term for a "nicely timed" death?

Those recommendations together almost sound like "write C in C++".

I sort of think about it the other way round, actually.

You can stop worrying about branchless code and have it generated automatically! ;)

The guy who was looking half a year for a bug in his code and then half a year for a bug in GCC (or something like that) only to find out that it was a bug in an AMD CPU.

Judging from the Matt Dillon case, a lot of "nah, the bug must be in my code" must have been involved.

One could make a number of arguments about at least half of these. Racket/PLT has been free for a long time but ten years ago, a friend of mine simply left it for Common Lisp for the sole reason of speed. Gambit is great - I'd say

Earlier accessibility of a top Scheme implementation could have helped make it more popular earlier. Just like with Smalltalk and Common Lisp before which also got into trouble because of good implementations being out of reach of most peop

Chez took too long a time to get freed. Had this happened a decade earlier, it would have been nice.
