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 required to power a high speed train when the sun is shining. 18,000 watts / 100 meters is 180 watts per meter. At 180 watts per meter, 50 km gives you 9 MW, which is about what a high speed train consumes at cruise.
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 a fire.
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-submarine warfare business in the 1970s and some of what he wrote in Red October I only knew from classified sources.
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 don't live in the US, which has a large number of IPv4 addresses per capita. Also IPv6 changes things.
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 packet and have it arrive at my house, and I can't send a SYN packet to your house. That means we are entirely dependent on the big guys like Facebook if we want to communicate with each other. Yes, there are some protocols like bittorrent that get around this, but that's the default situation today.
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 the early 1980s engineering workstations like Apollo and Sun, which also came out before Macintosh.
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. And there have been some huge costs associated with the wildfires.
There's a bit more technical info on California battery storage here:
Yes. This was more than 50 years ago. The store owner let me examine the device. It was wired into his alarm system. It even had the frequency listed on the label.
Children too. My own hearing extended to about 23 kHz until I was in my early 20s, and I don't think I was exceptional. There was a jewelry store in my town that I couldn't go in to because the "ultrasonic" motion detector was so painfully loud. But I doubt these devices would be a problem for children or pets because the pulse is so short.
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 "cd" to whatever tag, branch, or individual commit you wanted. No checkouts required. Very cool, I wish we still had that today. DSEE was spun off as Clearcase, acquired by IBM, then I don't know what happened to it after that.
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 1st Ave NE, which is way on the other side of town. And this isn't an aberration, most of the streets work the same way.
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 played popular or folk songs that the other musicians would have known. To answer your question, no, she was just another musician in my uncle's circle. I remember her because they worked together, not because of her music.
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.
It's a specific technique where you deliberately modulate the signal so as to interfere with the color subcarrier. This can be used to produce colors that are otherwise not available.
Engineering notebooks were required at my first job in the 1970s, for patent reasons. The notebook pages are numbered and it has a real sewn binding, making it harder to remove or insert a page without being noticed. We were required to date and sign each page and start a new page every day.
By the time I retired I think I was the only one at my company using one. I had to special order to get a proper one with the quad ruling, numbered pages, and sewn binding.
