--- Quote from: xrunner on July 05, 2022, 12:10:19 pm ---Got curious and found some info on iPhone 6s support. Might be ending when iOS 16 is out. Don't know any more than what I'm finding at the moment. https://www.macworld.com/article/561009/ios-16-support-iphone-6s-iphone-se.html --- End quote --- They say that somebody else says that someone else says that. At least they have the honesty to suggest themselves that you take it with a pinch of salt. :) That leads to a philosophic question. What classification goes with each of the levels of "someone said"? One layer "reliable intelligence", two layers "gossip", three "rumour", ..., six "wild unfounded speculation"? Anyway, continued support until Sept 2022 is guaranteed, anything after that is a bonus and I would speculate that, based on past performance, Apple are likely to stretch the support beyond the guaranteed 4 years. It's going to need a headline feature that requires hardware that only exists in the iPhone 7 and later before they have a real reason to drop support "on time". |

My guess is an inductor, but why that peculiar construction? * is there anything interestingly special about the reed relay, Electrol R4174-1 * how long would it take for a ferengi to spot the gold and other components? --- End quote --- I think it is a delay line. It's construction is a bit like a non-inductive power resistor but it's clearly not a power circuit. --- End quote --- Certainly not a power circuit. I presume the solidity is to ensure mechanical stability and hence electric stability. It might be a helical delay line, but from what little I've seen those tend to have an associated shield like a coax line. It might be a resonant helical delay line, e.g. used for sharp bandpass IF filters. It might be part of a low-pass filter; the "dielectric" would have low loss and hence a high Q. |

It's going to get released into the atmosphere and do what? Build up to become a huge big gas cloud that we are going to be breathing in and then one day a lightening strike ignites it and the entire planet erupts into a huge fireball and incinerates everything and everyone or worse, the planet blows apart and ceases to be a planet any more. :-// :-// :-// --- End quote --- You must be pulling our plonkers. Natural gas that has happily spent millions of years underground is suddenly going to start floating up into the air if we don't use it? --- Quote ---I don't know the answers really, and I'm pretty sure nobody else does, we may think that we do..but do we really :-// Looking at the animal / plant world for instance, it would seem that each animal, insect or plant has a specific role to play in the grand scheme of things and in one form or other all rely on each other for food and regulation. So how can we really be certain that fossil fuels aren't just a spoke in the great circle / wheel of life and that man was meant to discover it and use it like we do :-// Didn't early man have fires in their caves and use fire to scare off predators like wild lions etc. It makes you think what if... don't it? --- End quote --- That position that "each animal, insect or plant has a specific [designed] role to play in the grand scheme of things" and "that man was meant to discover" requires some variant of the "everything was planned, designed and made by [a] sky fairy/fairies" theory. I very much doubt that any sane sky fairy would plan for fossil fuels to exist just so we could use up too much of them to bugger the planet over. Then again, in most mythologies the sky fairy/fairies seem to suffer from one or more of the variants of psychological disorders along the narcissistic/sociopathic/psychopathic continuum so I suppose it isn't something that one should rule out merely because it would be the plan of a mad entity/entities. --- End quote --- Human beings have always created their gods in their own image. While I have no wish to offend those who do believe, and I appreciate the sense of community that organized religion gives some folk, I am a neutral in this war; an agnostic. I figure that if there is a god, and s/he is one worth believing in, s/he is going to have enough ego strength to deal with a honest skeptic. Under any circumstances... if you do believe, it has got to be very hard to reconcile our abject failure as stewards of her masterpiece, this planet earth. mnem As I grow older and a bit more jaded, I feel more and more that if there is a god, he is a fucking absentee father, and really needs to be taken out back of the celestial woodshed... |

Not sure why someone hacked-in a 7 segments display ? https://www.ebay.com/itm/134158692838 --- End quote --- IIRC, that "digit" is just a long neon bulb for a "1". I don't believe there is an actual digit, is there? mnem *knocks self unconscious with a nixie mallet* --- End quote --- Nope. :palm: EDIT: LOL!!! Specmaster found this very video while I was snoozing... :-DD mnem :-/O |

It is a scam to distract people. They invested more money in advertising it than to reduce THEIR "CF", whatever it is. |
