Talcum powder is at high risk of being contaminated with asbestos, you basically should not use it on your body because you can't be sure.
It has been known since the 60s, but it took until 2023 (and 30k lawsuits) for J&J to finally come to the conclusion that killing people this way is now no longer lucrative.
pfff, root, back in my day we hacked a vending machine with a lighter and got free coke.
No idea who discovered it, but the machine back at my school had an infrared interface for servicing, and you could trigger an interrupt with the flash of the flintstone of a lighter. Because it's just some 90s microcontroller, it would simply reset after failing to receive a valid command and forget what it was doing previously.
All you had to do was order a coke, and right when it drops out, before it subtracts the amount, you flash the lighter in front of the IR port like a magician, say the magic words and bam - free coke!
I used a saline glitch trick in the 90s. I cannot remember the exact sequence of events, but one injected saline into the coin or bill receptacle, which made the sensor believe money was being continuously inserted into the machine. This method had the benefit of clearing the machine of change after purchase since it registered the candy bar was bought with a substantial amount of money.
That doesn't work very well on a humid day outside in the summer.
And the payphones in the city I grew up in didn't operate using ground-start signalling, so the paper clip/safety pin/pull-tab/static trick didn't work there at all.
But an innocuous walkman with a cassette tape that had some red box tones on it, with a bonus of having the rest of the cassette available for music to listen to? That worked great.
This was in the late 1950's for me, in the San Fernando Valley where summertime humidity was very low. But a few years later the phone company put shields in the headsets so you could no longer puncture the foil.
I'm old enough to remember payphones being completely ubiquitous (with whole banks of them inside of each entrance for one large department store, usually with one or two more outside), but I'm not old enough to remember the 1950s. :)
I did find one old phone at a state park not too far out that could be tricked by grounding it, but that was in GTE territory instead of the Ohio Bell BOC that I was more familiar with.
That is not free, that is stealing. It's like going to a grocery store and calling it a hack that you can walk around the registers and leave without paying.
True. So sad to think that hackers are exploiting - and yes, there can be no doubt, this is EXPLOITATION - weaknesses in coin-operated services. I weep to think how far has this once-noble vocation has strayed from its roots ...
John Draper and his fellow hackers were EXPLOITING coin-operated payphones and switchboards in the 60s, so I'm not sure how far back you have to go to reach the noble vocation you describe.
> It does not seem very "viral" or income-generating
Yeah because that should be the end goal of everything right?
And from the response:
> 1. re: the first part, many people want something plug and play. and even if they were plug and play, the problem is that the user experience (on windows at least) with online drives generally sucks, and you don't have disconnected access.
Bingo. I am a really quite experienced Linux user (I've been using it since it came on two floppy disks and didn't really work) and I too want things that are just plug-and-play. Time spent dicking about making things work is time not spend doing something fun, although I get that for some folk their goal in using Linux is to "Be Using Linux". For most of us I suspect that extends out to "Be Using Linux to solve problems we actually have, not just be using Linux for the sake of it".
Makes sense if the drawers completely fill the volume of the fridge, so most of the air is inside the drawers and there is minimal air loss when the door opens. If the drawer fronts were insulated, each drawer would effectively be its own chest.
Edit: On a reread, I'm guessing you were talking about individual refrigerated drawers? Multiple drawers in a single insulated box (as I interpreted it) could work though, as it would have less exterior surface area, use less insulation for the same thermal resistance and useable volume and have a single cooling unit, which might be more efficient. It would also fit existing fridge alcoves.
If you designed around it, it would fit where existing kitchens have drawers, and the space typically reserved for a vertical fridge would be occupied by shelving. Kind of a neat idea. Microwave drawers are a thing.
Under-counter refrigerators are also a thing. They're often not cheap, though. KitchenAid has a two-drawer one for around $3,000. But you can find off-brand ones for $700, too. I don't know if the KitchenAid is that much better. There are things to take into account. It's not just as simple as 'put short, 24" deep fridge where drawers go."
