Desirable? Certainly! Practical? It depends. Modern packaging and surface mount technology do not lend themselves to replacement by someone armed with a soldering iron. There's no way an enthusiast can reattach a large ball grid array to a multilayer board with buried and blind vias. The connection points are simply not reachable. The world has long moved on from dual-in line packages (DIP) with through-hole vias and sockets. Maintaining spares for subassemblies is of course possible, but very expensive. Who would pay for this? 29 minutes ago, PupCam said: Aging effects are probably a minor consideration in the overall scheme of things I would have thought. The major source of obsolescence in semiconductor based devices, planned or otherwise, is the actual availability of replacement key complex and particularly programmed devices. Aging is very real. It is less evident with older, larger transistor geometries. My old Sharp calculator from the 1980s still runs just fine (or did the last time I tried to use it). What will the lifespan of a fast processor with billions of transistors, made in a contemporary <10nm foundry and intended for say an autonomous vehicle actually be? Of course these are built with safety considerations, but conceptually it only takes one failed transistor for a chip to no longer function. The problem of maintaining the foundries used to produce components from decades ago (or today's components for decades hence) remains. It's hit or miss. Some old fab lines are kept around for a long time but most of them are decommissioned and scrapped. Most of the companies that manufactured semiconductors as recently as ten years ago no longer do so, even if the company is still in business. 29 minutes ago, PupCam said: And even that doesn't guarantee long-term reliability of military equipment - go speak to the Army, Navy and Air Force! Of course not. Maintaining electronics inventory for 25 years or more is very problematic - in terms of physics and logistics.

The Mac on which ER issuing read just cannot keep up with it so it must be working faster. The CCTV - agree 'only OK for councils etc but not individuals'. - bet they are now 'good' neighbours - but ideally settings should only be for own premises these days - previously I understand they could not be 'properly' set. Gwiwer - I too have trying etc, qualifications and hated some of the training sessions that had to be attended particularly when they considered that 'a long dinner break' was needed - for me the shorter the break the better ( just in case know about 5 hours etc.). Antivaxers at schools -ID 'treason' sounds good and also like the suggestion that they be charged. Note that Covid infections are rising at all ages. Also noted that latest research suggests that 'LFT' is 90% correct (but with the proviso that they must be taken correctly). Printers - avoid HP like the plague if you need to print a lot - they do not accept other cheaper inks. There must be something wrong when ,generally apart from red, the cheaper versions work well at a fraction of the cost. Have to admit that currently am using genuine company inks from a tank.

The IET was formed in 2006 from two separate institutions: the Institution of Electrical Engineers, dating back to 1871, and the Institution of Incorporated Engineers dating back to 1884." They are professional bodies of academically qualified members. For example, the Institute of Advanced Motorists is an amateur organisation. I will also point out for reference (and will go no further on this soap box) that in all cases above, the word 'Engineer' is capitalised. Heating, refrigeration, plumbing and electrical (et alia) ""engineers"" who present to fix your household appliances are excluded! Hence the 'need' for salutations like 'Dipl Ing' and (IIRC) Eur Ing which have been introduced to trump CEng to reflect the academic status. Only in america was Casey Jones an engineer! Well I never did! And there is me .. a lowly CEng MIET not being allowed to make a small joke out of some of the Engineering Institutions.. to get to be a CEng MIET you had to have (in my case) at least an accredited Batchelor of Science Degree with Honours plus typically 5 years of Professional experience post graduation. (You now need an Accredited MSc). When I passed my hour long Appointments Board interview I achieved my new Professional Status which actually, in employment terms, gained me nothing but the need to pay an annual fee and to receive a lot of magazines which now seem to be proving that you can re_invent the wheel on a 10 yearly cycle).

As you are all probably aware they (the friends) are very much anti-drink. So it was a surprise that the hand sanitiser that they provided was whisky scented!

How many times has it kicked in since you installed it and for how long? Once for about five+ hours when a car took out a pole just up the road and another time for about two or three hours, but I do not know why for that one. There may have been a couple of other times but I have not kept track . The main reason that I got the thing is for heat in the winter to keep the pipes from freezing, water as I am on a well, and to keep food in the icebox from going bad. When I lived in south Florida, I was once without power for three weeks after Mrs. Wilma kindly paid us a visit. My neighbor had a generator and I would drop off my ups in the morning on the way to work and pick it up when I got home. I had my computer, light, and a small fan in the bedroom. Plenty of canned food kept me going and some ice brought home from work helped in the beverage department. 1 2 17 Link to post Share on other sites More sharing options...

RMweb Premium Popular Post Dave John Posted October 14, 2021 RMweb Premium Popular Post Share Posted October 14, 2021 I don't normally wander into wheeltappers, but I saw BarryO s quote and read up. I have almost the same letters as you, but mine is a B.Eng. I'd agree, nobody much has a clue about what it means and its all kinda pricey for a magazine which these days veers towards the philosophical rather than the practical. I liked it with MIEE, I do feel I fit better as a hands on engineer. Whether that is an engineer or an Engineer matters not a jot, I potter on doing a bit of real engineering, mainly involving historic buildings. So , here is one I did earlier. Design and install, all on my own. 800 m + of armour . Sorry , late night post, but sometimes it gets like that. 21 2 Link to post Share on other sites More sharing options...
RMweb Premium TheQ Posted October 15, 2021 RMweb Premium Share Posted October 15, 2021 (edited) Mooring Awl inner Temple Hare, 4 hours sleep so far, I'll try for more shortly. At one point I was working towards letters after my name but the increasing level of qualifications needed for them just made it impossible. It was noticeable for maybe the first 25- 50years of such institutions there were no qualifications needed because they didn't exist. Later those making the requirement for the ever increasing qualifications generally didn't have them, and were trying to turn them into smaller private clubs. A bit like who taught the first teacher.. I'm sceptical about many of the qualifications required for some jobs. But on the other hand, I'd like a legal description of what for instance is an engineer, and other grades. Many are given over inflated titles for what they do and have training for. At one point I bought a generator 3kw, enough to keep essential services going. As we got maybe half a dozen power cuts each winter.... Manual start, turn off mains input, open the garage door start generator.. Whereupon they replaced many electricity poles in the area, and replaced all the bare triple power lines with triple twisted insulated cables.. Since then hardly a power failure.. and the Genny hasn't run for some time... Somewhere I've got a ups, mains power in, socket on the output. Power fails computer stays on for a half hour.. However the batteries inside have long since failed, and the ups is sat in a cupboard. GEC and the company I currently work for, have done a lot of work on keeping things supported for at least ten years after last production, it's a military requirement as well as good business. For PCBs it's generally a stock of spares as many are unrepairable even for us. Sometimes a routine commercially available spare that they thought stocks of spares would not be needed for, goes suddenly unavailable, and a new board using replacement part gets rapidly designed. This happened to one of they high accuracy thermometers I calibrate, the main A to D chip became unavailable. So they had to design a complete new thermometer, and offer it at a substantial discount to those who bought the old one . Time for more sleep..

Prompted by Stewart, I have worked out the travel timings and look forward to my first breakfast in 'Spoons, at St Pancras, for quite a while. The line to Uckfield is an island of diesel power in an electric ocean and will make a pleasant change. Before all that I need to garner essential supplies.

RMweb Premium Popular Post Barry O Posted October 15, 2021 RMweb Premium Popular Post Share Posted October 15, 2021 Ey up! An interesting meeting last night with some County Scoters Officers. A great group of very knowledgeable people. I am trying to get an appointment for diabetic blood tests etc as well as a discussion on why my medication is giving me cramps .... the Marie Celeste sails serenely on with the phones unplugged... when I visited last week for my flu jab, two receptionists were on duty..neither were answering the phone calls coming in... It costs a lot of money to be a member of an Institution. These continue, as @Dave John pointed out, to ramp up the educational entry requirements for new members. Strangely there are a lot of Academics in top level posts...I can be very cynical about the reasons why the education requirement continue to rise. and on to Friday. Should I have bacon and egg for breakfast? Should @chrisf find a moreasons to try their less substantial breakfast? Questions, questions... Stay safe! Enjoy your day however you can! baz Drivelling on in the North West Leeds Highlands. 19 2 1 Link to post Share on other sites More sharing options...
Popular Post iL Dottore Posted October 15, 2021 Popular Post Share Posted October 15, 2021 Good Morning, Friday awaits and I, for one, can’t wait for the weekend to begin. Toddled into town yesterday with Mrs iD and the doggies to see our financial advisor (given that nearly all Swiss have private pensions in various forms, it is not unusual for a Swiss to use a Treuhand and a financial advisor). Apart from the “good” news that I’ll be working for another two - three years post-retirement (I should have retired this year!) there was also the news that cash savings aren’t a good idea right now - as inflation is foreseen for the near future: good for investments but not for the piggy bank - apparently Inflation could be a problem for Switzerland as the Swiss are serious savers: the Swiss manage to save - on average - 17.47% of their household income (2nd in the world after Luxembourg at 18.09%). PostFinanz (the savings bank of the Swiss Post Office) alone has 124 billion Swiss Francs of customer savings. (Captain Cynical is now wondering what to do with his £1.56 billion in small change…). Like many of my generation I was taught to be thrifty (which is not the same as penny pinching or being mean with money) and consumables that are designed to fail and/or be unrepairable are a particular bug-bear of mine. A fairly well equipped workshop does help as does an old set of screwdrivers adapted to deal with security screws - but even so… What’s even worse is that the few local repairs shops that there are around here, charge an average flat fee of around SFr 150 (about £120) just to look at an item - repair work and spare parts extra.. So much for “recycling”, “upcycling” and “saving the planet” ID 4 2 14 Link to post Share on other sites More sharing options...

RMweb Gold Popular Post grandadbob Posted October 15, 2021 RMweb Gold Popular Post Share Posted October 15, 2021 Good morning all, Very dull out and from what I can see it is very cloudy. The forecast mentions patchy rain but none here at the moment and the skies should clear later leaving us with a dry and bright day. Good Oh. Usual early morning aches and pains in back and limbs which will hopefully ease when I get off my backside and move around a bit. The ongoing lack of enthusiasm for decorating abounds but I better do something. I'll be on my own today as The Boss is going to Nicki's for the day to help her with some housework as she still can't do anything very strenuous. Bin men didn't come yesterday, seems like this is now going to be the norm for a while. Tea needs to be offered to Herself so farewell for now.

RMweb Premium New Haven Neil Posted October 15, 2021 RMweb Premium Share Posted October 15, 2021 (edited) Morning from a 5c, dry, still and chilly rock, where 'People Management' magazine no longer darkens the doormat. The high point of CIPD membership was seeing that same title parodied on 'Have I Got News For You'! (Edit: IIRC Angus Deayton 'outed' his brother as a member!). It had one page of interesting and professionally relevant case law, and many of job adverts and other fairly meaningless drivel, for which we had to pay a tidy sum each year for membership. Which of course I no longer do, therefore technically cannot use the letters after the handle. I should like to point out to detractors though, that my HR practice was in the NHS, where we treated staff as valuable humans. I did spend a year as the Medical Staffing Officer, basically recruiting doctors, which gave me a hearty dislike of many of them though. Oddly, recruiting Consultants, whom you would imagine to be the most difficult, generally were fine to deal with, it was the junior doctors who were a long way up their own......opinions. Oops, bit of a rant. 'Marine Engineers Review' had at least interesting articles about developments spread out between all the adverts. I see it is now IMarEST, things have changed, but is still an Institute, as is the CIPD. Edited October 15, 2021 by New Haven Neil 15 1 3 Link to post Share on other sites More sharing options...

Popular Post Sir TophamHatt Posted October 15, 2021 Popular Post Share Posted October 15, 2021 Morning all. Not a great start to the day. Mrs STH messaged saying the boiler was low on pressure again. She thinks the boiler filter that was serviced nearly a month ago looks wet. A couple of weeks ago, we figured this was a point of failure so they came back to fit the one and only replacement O ring. Seems like it's still been leaking, which means everything below it is likely damp now. But as they don't make that filter any more (apparently it was old when the installer put it in just two years ago), difficult to get parts for it, which means at lest £250 for a new filter (and having to move the fridge again for space), which I don't really have to spare right now. It's more the hassle of it all rather than the cost. I don't know if I should approach the original installer or try the manufacturer but it's just over the two years old of the guarantee as due to covid, the date the boiler got serviced was a few months different from when it was installed. A local boiler servicing company was pretty good last year but this time, it seems like the guy was rushing a little. Just don't want the hassle but also don't want to let it lie if the first service person has initially damaged it - worked fine up until then. 20 Link to post Share on other sites More sharing options...
