OP put in 60 amp service. I can't imagine why you would need that much, even with the minisplit. My flat is three times the size of his office and has an electric water heater and washing machine and it has 32 amp service.

In 2000 you could go to the library and look up the number in the Polk directory. There was one for each borough. There was an alphabetical section, a section by street address, and a section by phone number. You can still go down to the li

Also about 16 GW. They don't say what the installed capacity is but average midday generation is 40 GW for usage of 40% which is not bad.

It uses R-22 so it's pretty old, but probably not 1950s. Maybe 1970s. R-22 was phased out starting in the 1980s, and banned in 2010 (that's in Europe, maybe later in US). When I lived in the US I tried to get a minisplit and they

Serious and maybe stupid question, also note I don't live in the US. Is this really needed? If you put a scoring pad and a couple pencils in each lane would your customers say "what is this shit", turn around and walk out?

What a useless article! I found some actual information here: https://www.techspot.com/news/97995-data-center-uses-waste-h... The "data center" produces about 28 kW of heat and the swimming pool has cut its g

It's obviously not 180 kWp/m. If it was I could put 1 meter of panels on my roof and power my house and 200 of my neighbors. I didn't try to calculate the amount of energy it produces in a year, just the length of panels requ

by dn3500 2mo ago
They're getting 180 watts per meter, so it would take 50 km of panels to power one high speed train. And that's when the sun is shining. Double this at least if you want to store the energy and run trains in the evening.

In the US Navy at least, you don't "fire" a torpedo, you "shoot" it. The lore is that "fire" has a very specific, very urgent meaning on a warship and you don't use that word unless there actually is

I'm not a handgun expert at all but I've caught a few of these, like the guy who racked the slide on his revolver. The author who really impressed me, although not with his handgun knowledge, was Tom Clancy. I was in the anti-subm

You could be right. I haven't had one since 2018. ChatGPT says 70% of residential customers worldwide do still have routable addresses so I may have spoken too much from my own experience. I'm sure it depends on where you are, and

I was there when we turned on the Internet in 1981. At the time I would have defined the Internet as the set of all endpoints reachable using IPv4. By that definition, none of us today are even on the Internet. You can't send a SYN pac

I don't understand the kernel problem. Why did he feel he had to rebuild the kernel weekly? When the amdgpu stopped working why couldn't he just go back to the last working kernel?

Square pixels were certainly not an innovation of the Macintosh. The earliest raster scan workstation I'm aware of is the Alto, released in 1973. It and the ones that came after it like the Star and Dorado all had square pixels. So did

California imports a third of its electricity, and that's expensive. It gets almost another third from natural gas. They've been changing rapidly from fossil fuels and nuclear to renewables and that's pretty capital intensive

There were several proprietary systems in the late 1980s and early 1990s. The one I remember was DSEE from Apollo Computer. It was integrated with the file system such that commits and branches worked like zfs snapshots. You could just &quo

Seattle is crazy. I used to live on 1st Ave N, which is the same physical street as 1st Ave and 1st Ave S, but don't confuse them because they all have their own numbers and some of them overlap. It is however completely different from

That's why I wish I'd paid closer attention. If she played her own compositions, I wasn't aware of it. My aunt and uncle were both serious amateur musicians and often had people over to play music. It's more likely they

I knew her in Ann Arbor. By then she had stopped performing but I heard her play a couple of times at my uncle's house. I now wish I'd paid closer attention, I was just a stupid teenager at the time.

I bought a Tektronix 4014 in 1991 and had it until 2016. During that time it never required any repairs or calibration. Built like a tank. The guy I sold it to had to replace capacitors in the power supply, and still uses it today.

I live in the tropics and there is plenty of sunshine here. So my skin doctor told me to avoid the sun at all costs, always wear suncreen and a hat, don't go out in the daytime. A few years of that and now I have a vitamin D deficiency
