--- Quote from: Specmaster on July 04, 2022, 06:57:42 pm --- If companies also perceive that Android is a serious threat to their security, then let them issue iPhones / Blackberries to their staff. I have never known a company that actually expected their staff to provide a mobile phone, it was always a company asset and had to be handed back upon leaving their employment and strictly NO private calls were allowed. --- End quote --- Blackberry is dead. in Sweden, people provide or get issued phones, depending on work. I've had an issued phone the last 26 or so years, and the restrictions on private calls have initially been different. My stance was, that either $EMPLOYER swallows the bill, no questions asked, or I turn the phone off when I leave work for the day. It's worked out well. Employer did not make a fuss. With the phone being very much a infocentre for your complete life (and that's something you can't avoid, period.), the question is if you want your employer to own your phone. I chose to split work and private phones simply because of this. And I'm very much conscious what apps and which data that go on which phone, just because. Today, one gets free minutes and SMS, in the entire EU, and a sensible blob of data. I get 25GiB a month on my private phone. Never run out. My work phone gets unlimited data in Sweden and something like 100GiB in the EU. And free calls/SMS. The US market of course is shat, and the UK will be too, but that's something you can thank the über-twit Rees-Mogg for. Bottom line, you get a working phone or you lose. It's not nice, but that's where it is. We chose to give our children second-hand iPhones that have been professionally refurbished, and that keeps cost at a reasonable level. For computers, the curve isn't as steep. At least if you buy a sensible computer. My laptop is very old; a "Early 2015" 13" Retina MBP. It still runs a supported OS, and it works for my needs; but the battery is near-toast and the storage is full. Both can and will be dealt with this autumn. The work computer of course is newer, a 16" Intel MBP with large storage and barely a year old. Those muscles are needed for "Bad web sites turned into apps" like Teams and others. |

Oh boy I didn't think old cars coudl be so much fun on TEA, almost as good as old floppies eh ? ! :-DD Suddenly I am thinking.... what if I shoved a floppy into my Safrane's tape deck ?! What might that produce, even MORE fun ?!! :D |

Discussions about the efficiency of cars is somewhat physics related. But, please, can we stop talking about or mention political situations? In my opinion, this is pure whataboutism, especially here in the TEA thread. It doesn't help at all, except pouring more fuel into the fire. Thank you. |

I've never had this problem on over a dozen 546xxx scopes where I've serviced the panel; every one has come back 100%, even this most recent 54600A, which literally had spots eaten out of the PCBs... Are you guys scrubbing both the PCB and the pads on the membrane with IPA? You have to, both front and back in order to get a reliable read. I don't use Q-tips; I scrub both the membrane and the PCB with a cotton kitchen towel (fine short nap; terry loops will snag on solder joints and edges of PCB) soaked in IPA. Trick with the membrane keypad is to hold the body of the button in one hand and scrub each one individually; this allows you to scrub the conductive pad pretty aggressively with the IPA/towel in the other hand. I also scrub around the solder joints on that intermediary cable with IPA and a toothbrush; that area collects cruft due to the tape stuck over it and will make the scope misread as it scans the buttons. On assembly, just leave those solder joints bare, or if you're anal aboot such things, a fresh strip of Kapton tape over the solder joints. Also, it is important to loop that ribbon cable exactly the same as HP made it; if you fold it over itself you'll have poor read problems. mnem :-BROKE --- End quote --- ok, mnem didn't like the use of aluminium tape over those carbon buttons in the 54622d switches. so i went to michaels craft store and bought a book of silver leaf. pulled out the aluminium rectangles and replaced them with silver leaf of the same size and shape. used a cotton ball to push it down on the buttons. exercised all 6 switches a bunch of times and then pulled it apart for visual inspection. looks good. if anything the buttons now seem even more sensitive than with the aluminium tape. i expect that mnem will now advise a trip back to michaels for gold leaf. ok.....silver tarnishes, but silver tarnish is highly conductive and should not be a problem. will it fail eventually? maybe. |

You end up paying more keeping something which is why I got rid of that fucking awful Fiat and will be getting rid of my Citroen soon. Edit: rise in fuel prices = inefficiency liability. --- End quote --- This might make you rethink that strategy --- End quote --- LOL no. 19-23 mpg. In no way that makes sense. Even in America. --- End quote --- No, I wouldn't either, but the points he raises are what I was hinting at. If you have a car that is running well, reasonably cost-effective to run and has no major body / rust / mechanical issues, then why the hell risk junking that for something like he says that is really designed with the good for 70,000 miles ethos and then scrap it for another plastic car etc, which is not good for the planet either. --- End quote --- That doesn't make economical sense here due to the petrol prices. Say 2014 C3 ... 100k miles lifespan for a car at 66mpg, that's 1515 gallons. 4.55 litres to the gallon = 6893 litres ... £1.92 / litre. £13,236 for fuel Say Vince's Safrane ... 100k miles lifespan at 34mpg, that's 2941 gallons. 4.55 litres to the gallon = 13,382 litres ... £1.92 / litre. £25,694 for fuel If you sell the Safrane and buy a C3 with 25k miles on the clock it'll cost you £6000. In 100k miles you will be better off by £6,694. The safrane is worth £0 when you sell it. The C3 £1200 at 100k. Put the £6694 in the bank, buy a nice smartphone with the difference and then get a newer C3 in 3-5 years. Total cost of ownership is MUCH lower with efficient engines. The scary thing is if I sell my C3 now it's worth £1000 more than I paid for it because the rising fuel prices are compressing the market into efficient cars. --- End quote --- Well that argument does to some extent hold up, until you consider the fact that Vince says he has no money, so he would have to burrow the 6K but from who, with no income no bank etc will entertain a loan, its a vicious circle, take any one link out of that circle and it crashes. Now it seems that the worlds most efficient engines use a cylinder capacity of just 500cc and the world's best overall compromise in engine size a 4 cylinder 2 litre engine which is mine, diesel is also more efficient than petrol, as it squeezes more power and MPG from its fuel. So with that in mind, why doesn't the worlds Govts make it must have engine size in all new cars, banning anything larger. That really would concentrate minds on how to squeeze even more efficiency from the engines in all aspects, power, MPG and also emissions which would benefit everybody and the planet right now? |
