Did something similar to OP. I was writing a controller for a streaming system and managed to accidentally set the volume to 100. This was with speakers not headphones. I had to pull the power plug to stop it. Just about gave me a heart attack.
The bug was a feedback loop in the volume control code that somehow ramped the volume up without any way to stop it. After that I always tested with a physical volume control later in the audio chain, with the volume set to a medium level.
It looks like 5 1/4” drives themselves are getting quite rare, not many on eBay, while there are lots of 3.5”. So even with a controller, getting a drive is not simple.
I’d say the main reason, is that 3.5” drives are much more common, and they overlapped USB They are much more standard than 5 1/4” drives too.
Ray Holt also went on to design the Jolt computer, a very early 6502 based computer which lead to the SYM-1 (also designed by Ray Holt), and TIM-1, which was more of a kit with a pre-programmed ROM. I built my own TIM-1 this year and have been doing a bit of research into these early 6502 boards. The Jolt computer is perhaps most famous for being used as the microprocessor section in the first Atari 2600 prototypes.
Cheese is low in lactose, and gelato is too, it's mainly sugar with only a little bit of milk.
Someone I know, who is lactose intolerant, believes that frozen milk isn't as bad, I've not found any scientific evidence of this, so it's probably not true, but she thinks she is more tolerant of frozen milk products, so maybe there is some reason?
There is also not that much milk in a serving of ice cream since it is usually less than the 1:1 with amount of cream, typically 2:1 cream to milk, plus sugar, stabilizers, flavorings. A milkshake would be much more milk though I’d think.
A large grid is harder to manage and runs the risk of a cascading failure. Especially as HVDC is a lot cheaper and more efficient than it used to be, there's an argument we should actually be breaking our grids down further.
Consider the distance, and speed of light, and the speed of electricity (1/100th of that). I don't think it's truly feasible to keep that much physical space in sync. Hmm...
The speed of electricity isn't 1/100th the speed of light. IIRC it's something closer to 70% in copper. The speed electrons move is much lower, however something more like cm or m per second (presumably depends on voltage.) However, this isn't related to the speed of electricity which is analogous to how the speed of water through an (already full) hose isn't related to how soon water starts coming out the end when the tap is turned on.
I've also heard, but I can't explain so you'll have to look it up yourself, that none of this matters when keeping a grid in sync anyway. It just works out.
That's not a very large area, to be fair. That's about the size of half of the United States, in distance/spread. Europe isn't a continent in the traditional sense, it's a region, and not a huge one.
This might counter the grandparent poster if Asia was on the same synchronous grid, but it's not.
I guess there's two ways of looking at it. The distances spanned by the extreme points net or how dense it is. Not that I have the knowledge to relate any of that to real world use cases or consequences.
The details always matter in these kinds of statements, and I guess there is often exaggeration in a lot of claims to have designed things. Someone that made a one sentence comment on a design then claims to be the one that actually made it work. It’s clear that Woz was a uniquely talented hardware designer, but he also wasn’t living in isolation (although imagine what it would have been like if he had the internet).
In Chuck Peddles oral history at the Computer Museum he has this to say about Apple:
Peddle: Apple II. OK, so Apple I. Peter lived in the Bay Area, and he was my salesman for the Bay Area. So he was selling Atari and all that sort of stuff. And we went to two or three other of his customers and helped them with the ICE. And he called up and said, hey, we got these two young guys working on this computer in their garage, and they can't make it work. So Peter and I took the ICE down, and we made it work.
Peddle designed the 6502 and a lot of 6502 systems, he would have been a great person to have around to get your design going. And an ICE (In Circuit Emulator) would have helped too.
The article does have two good topics, and I can see the connection, but it does detract from the message. There are some very important things said about Coronavirus, and USA should be taking notice of this right now, but unfortunately if I forward the article on to someone, the first thing they will read will be some PC industry history.
I've been living in UK for a long time and working on some very large projects, mostly at architecture level. Now I live in a small town and am looking for remote work. I have a lot of experience with iOS development, and a bit with Android. I've been working with Objective-C since 1991 on NeXT computers. Lately I've been doing contract app development but would like to work on larger and more challenging projects. I've also been doing some more diverse work lately, including a complete system including embedded development, LoRa radios, and a Web management console running on Raspberry-Pi. I've also built a lot of audio apps and know streaming technologies well.
