  • Ah that makes sense.

    I think another thing that might be uniquely Canadian is when you're paying at a drivethru and you see the machine emerge from the pickup window taped to the end of a hockey stick. That was a big thing during the pandemic for social distancing. I guess more recently, they've been moving to less improvised solutions, which is a shame. I really liked the hockey stick!

  • The cash I have on hand comes exclusively from playing pub gigs in a band. That is still very much a cash-driven economy where I am. When I accumulate enough, I usually wind up spending it on music gear, so I don't think this hobby of mine is major wealth-builder. But while many businesses are moving away from cash, it seems music stores are used to people like me and still allow fairly hefty cash transactions.

    The other day I was settling my tab at the pub and the guy hands me a machine. I say, I'll pay by cash thanks. He says really?!? Dude, you literally just handed me cash for the gig tonight. Oh yeah…

  • Canada has universal tap to pay also, but what surprised me about the UK—at least in the London area—was how quick it was? The payment processing was near-instantaneous. In Canada, I think the machines make a phone call behind the scenes to a bank or something? There's a significant delay before it goes through.

  • Yeah that sounds awesome!

    I was just trying to say that once you privatize something like a mall to make it housing or whatever it is, you will never get it back. The city or some public trust should hold onto the property. What you actually do with it depends on what would be best for the community I guess?

    Being a Canadian, just having some indoor places where you can gather in to get out of the cold in the dead of winter is something I don't think we should give up.

  • I can't say too much about it but we're in the mining sector.

    And yeah, if I had to do it all over again from scratch, I'd definitely be looking at a real-time OS. There just weren't many options back in the day besides coding it all yourself. Even now, I'd have to benchmark the OS to see what its latency is actually like? We had it down in the microseconds range with our custom OS but if it's more like milliseconds with an off-the-shelf OS, for example, that would change the whole ball game.

  • Well we built some instrumentation around it at work back in the 90s and still use it today. It was ahead of its time. It had hardware loops, a hardware call stack, hardware circular buffer addressing, and a DMA controller. In one instruction, you could do 2 FPU operations and a memory move with a DMA transfer going on in the background. It was an insane architecture. And it could handle 3 separate memory spaces, so even though it's a 32-bit chip, you could access well over 4 GB of RAM.

    The best thing about chips of that era though is you could tell ahead of time exactly how long your code will take to execute. Like you just type numbers into a spreadsheet and add up the instruction cycle counts. That kind of analysis is hopeless these days, but it informed the design of the instrument. More recently, we've been looking at RISC-V for a newer generation, but it's harder to predict ahead of time how it will perform?

  • If you need an expert on the long-discontinued Motorola 96002 digital signal processor, I'm your guy! I wrote an entire graphical operating system in its assembly language and still need to maintain it from time to time, so my skills remain sharp.

  • Be sure to look at what they consider a serving size is when you do this. I've seen cases where you have something that is packaged as a single serving, but the nutritional facts say the serving size is half of that. I think this is just criminal. Like anyone would eat only half an instant ramen or whatever.

  • Well the toothpick shifts to one side as you put the screw in.

    The problem with a stripped hole is that the hole is now as wide as the screw, so the screw has nothing to grip anymore. Conventional wisdom in this case is that you should get a wider screw and try again, but that's not always something you have on hand, especially when travelling.

    But the toothpick hack takes it the other way. It's effectively narrowing the hole again by taking up space in it, and now your same screw can work again.

  • My experience with exerting in the winter is I start feeling hot around the neck and upper torso first. So if I'm wearing a thermal jacket below a windbreaker, I'll start with leaving the thermal zipper down a bit but have the windbreaker's up all the way.

  • One time I was in Mexico with my wife while our daughter was still a baby and the lady at the front desk of the hotel where we were staying offered us a crib we could borrow. It was a kind gesture, but I was a little concerned because the crib seemed wobbly. I realized there were some screws loose but though I had a multitool on me, the holes were stripped.

    So later, I was talking with a local and he's like "I can fix that." He comes over and pulls a pack of toothpicks out of his pocket. He sticks one into each hole and breaks it off so that it's not sticking out anymore. Then he drives the screw back in. I shook the crib after that and it was rock solid!

    Now I always keep some toothpicks handy. Fast-forward to just this year. My daughter is now an adult living in a condo, and was complaining the screw popped out of a kitchen cabinet door when her roommate yanked on it too hard. "I can fix that."

  • The thing about the MPW Shell is it was sort of the only game in town if you actually wanted a command line with the classic Mac OS. (There's an awesome little emulator called SheepShaver if you ever want to explore it btw.) Well, I suppose there was A/UX. I thought it was a miracle when that came out. You have to realize in those early days a good chunk of the operating system itself was actually baked in to ROM. (You had to do desperate things to squeeze a GUI out of such limited resources as existed back then!) So to this day I have no idea how they managed to spin off a 'nix despite that.

    Anyways. I wonder, if you made some sort of template format today, to what extent you could write some sort of conversion tool that would scrape a man page or whatever to rough it in and then you could tweak it to get what you want? man pages aren't super standardized in their format I guess, so it's probably more trouble than it's worth. I like to use Python's argparse when rolling out scripts myself, and its --help format is pretty rigid given that it's algorithmically generated. Might be more plausible with something like that? I had a quick look just now to see if you can drill down into the argparse.ArgumentParser class itself to pull out the info more directly, but it seems a rather opaque thing that doesn't expose public APIs for that. Oh well…
