Inexplicable things have been occurring around me this week. In other circumstances, this might be fun. With the grim …

    Sounds familiar

    I gently ask my trainee to click on a menu. In response, she clicks her mouse frantically 279 times on random things all over the place before grabbing the title bar of her one remaining document window and dragging it four fifths of the way down her screen. Only then does she click on the menu I suggested.

    I only have to do training a couple of times a year these days, but I always seem to get one of these people. Maybe I did something wrong in a previous life.

    That paragraph did have me genuninely laughing out loud.

      Some people apparently instantly lose no less than at least one thousand IQ points as soon as anyone steps up behind them (while they're sitting at a computer) attempting to accommodate a request to enlighten them. Clicking absolutely everywhere completely randomly for some unexplainable reason, as depicted, seems to be one of the symptoms of this, almost as if it were some form of "padding action" of a thoroughly paralyzed and blanked-out brain, similar to people making "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaah" sounds between words while they have no idea what to say just to avoid shutting the hell up*.

      *some of the lowliest scum actually do that on purpose just to "hog the channel" at all times trying to subdue everyone in the group, making sure nobody gets to speak their mind except them in a "conversation".

      I too, do a few training course a year... any more and I think I'd go postal.

      Some highlights from the last one - student is a 'sys admin' for a company. very 'windoze' focused. This product was on Linux.

      Firstly again and again issues with him typing commands in the wrong case, and then after it being explained to him that linux is case sensitive moaning and complaining.. only to do exactly the same thing about 20 minutes later...

      Vi... oh christ.... it took 30 minutes to walk him through editing one line into a file... no.. press I.. now type the line... no you didn't press I... no you need to start again.. press ESC ! x... ESC - it's the top left... no don't hold it down.. just press it once, press ! then x.. ok now lets start again....aaaaaaaaahhhhhhhhh

      but the best were these 2 gems:

      ok, you are on the command line. type ls -al

      ok what do you see ?

      nothing

      you did ls -al.

      yes.

      in lower case.

      yes

      ....did you press return ?

      no.. you didn't tell me to...

      aaahhhhhhhhhhhhhh

      But the best one... was setting up a linux VM:

      I was on a mac, he was on a windoze box. I took everyone through all the setting the static IPs up, etc - I told them DO NOT COPY MY IP on the projector, use the one your own PC has given the VM (and walked them through ifconfig).

      2 painful hours of setup later, this bod isn't working... turns out he DID copy my IP ranges (172.* instead of 192.* on windows)... then of course, being the 'one eyed man' and this being a windows things... tried to changed vmware player to support the new ranges, and fucked everything right up - nothing worked.

      We were in a classroom with clean PCs, so I figured the best thing rather than spending hours trying to work out how he'd broke this one, was just to do it again properly.

      "OK, it's all screwed up, just go to the PC on the next desk and do that task over again"

      I got on with the rest of the class.

      An hour later, I checked on him - how you getting on ? is it working now ?

      no... same problem.

      same.. how ? I mean.. oh ASFASFASS#@$%%@#^%@#^%%%!!!

      yup.. he has indeed did the task over again... again using my IP address, again hacking the fuck out of vmware to try and get it to work.

    "This means it'll be precisely as reliable as the cheap one he's replacing."

    Ah - but was that the root cause?

    I sold my old car after 13 years to a dealer. Several years later a knock at the door announced a subsequent owner who was having trouble with a flat battery. Being a helpful sort - and it was nice to see my car still going - I took a look under the bonnet. I did point out that doing car maintenance outside on a freezing winter's day was one reason I had stopped owning a car.

    The problem was quickly diagnosed. Someone had replaced the alternator with the wrong type. I had refitted the vehicle with a blocking diode dual battery system that required an alternator to sense the voltage at the battery terminal.

    I asked him if he had looked at my circuit diagram that I had added to the car's workshop manual. He said he hadn't had that manual passed on to him when he bought the car. I doubt if the boot still contained the super strong wheel brace either - that had proved to only way to change tyres without a garage's tools.

      At least was she hot...? Otherwise I can think of quite a few candid words I'd use in a similar situation on a request for assistance with a vehicle I long since no longer own - "oh wait, you're serious - let me laugh even harder" being the absolute mildest of them.

    My colleague has just returned from Excel training...

    And wants to use the fantastic features he's been told about. But he can't find any of them on his desktop. He produces his training manual. Excel 2013 on a Windows 8 machine - one version behind the official company build, which is odd seeing as though the course was delivered by a company trainer in a company learning suite.

    "Where's the view panel in the ribbon?"

    "You don't have one. Use the view menu instead."

    "But I want it to be the same as my manual..."

    "You have a Mac running Office 2010. The functions are all there, but they will be in slightly different places."

    "But why isn't it the same as my training manual?"

    "Because you are using a Mac with Office 2010. This is for a Windows 8 PC running Office 2013."

    "Oh, Ok. But look at this... I can see all the formulae at once if I just... Where's the alt-key? And where's that key with the little bar with a tail at the right hand end?"

    "You're using a Mac. The keyboard has subtle differences."

    "But I want it to be like it is in my training manual."

    "You're 57 years old. You have a PhD. You have been using a Mac for over 10 years. You have been using Excel for over 10 years. Why did you want to go on a training course to learn how to use Excel?"

    "I didn't think I knew enough to be getting the best out of Excel."

    "You are currently getting no use out of Excel. You've come back in a worse state than when you went. All the basic ideas and concepts you've learned these last two days are valid. The options are there, but they might be in a slightly different place."

    "Why isn't it the same though?"

    "Bec... Oh FFS. Here, have a PC."

    "I don't want a PC. I like my Mac."

    etc etc etc until I was rescued by someone who had managed to remove some wires from the spaghetti explosion behind the videoconferencing unit. Again. And bending over upside down with a torch clamped in my mouth, straining my weakened back muscles and compressing my lunch-filled stomach, whilst reaching into the electronic equivalents of the intestines is far, far preferable to trying to explain why some people shouldn't go on training courses.

      One must not mistake "make the real word fit my mental image of it, serf! Immediately!" demands for the innocent-sounding "questions" people try to disguise them as. I don't purport to have a solution to this problem, but it's important to recognize it's not information they're actually asking for, it will not help to answer the question or indeed any number of questions, and they will definitely not adapt to the way things actually work. The only appropriate response to these people is "fuck right the fuck off you entitled fossil" but unfortunately expressing that openly is not actually an option in most cases.

      And only in this one case do I love the Reg's fading off into oblivion of the "rest of the story".

      It perfectly states the mind-numbing changes that have been made to this particular brand of products --- moving menu items, adding candy ribbons, taking over Alt/Cmd sequences, dumbing down everything, forcing "schemes" into gawdful limits.

      I participated in one of these brand focus groups way back when. Of course I am a developer and have a tweakish nature but most of the changes implemented seem to be from a group that only included the 45-55% percentile, a lot of color-blind UI experts, and pseudo-UI-experts that failed optimization of spacial usage tests.

      So much of the wannabe new UI has forced many of us back to that most primal and most effective one: CLI.

    There was a time when I bought a second-hand Mini-Moke. It was painted purple with flower stickers - so I had it resprayed to white.

    After a while the orange dynamo light on the dashboard showed it wasn't charging unless you revved hard. Adjusted the regulator settings - but it made no difference ...except the low oil red indicator was then lit and the battery went flat.

    Then the penny dropped. During the respray the garage had removed the speedometer - which contained all the vehicle's primitive instrumentation of two bulbs for "charging" and "oil". When they refitted it they had swapped the bulbs into the wrong holders. The problem had been that the oil needed topping up.

    Level of trainee

    Sometimes you may have a trainee that can work like an airline pilot and needs to speed through the technical stuff ( I dunno, never had that problem).

    Mostly they will more like fear of flying than airline pilots, techno-phobics, Some of these at least will be on a course in Advanced Office, when they should be on a course for computer basics. And some of those will be there because they are under the cosh. Often for the simple reason that they are terrified of the computer they need to be able to use.

    The random trainee

    I delivered some training in the past, and sometimes you have to accept that some individuals are simply not suited to the job they are being trained in/applied for.

    In my case the employer put up with described individual for years, despite no clear change in behaviour (no idea why). It ended up being quicker to just do their job and let them have a cup of tea.

    I have though, committed the reverse crime of pointing out inaccuracies in provided course notes too. That is just as frustrating for the trainer..

    Battery box...

    We had a Peugeot 206 1.4LX petrol, third owner, only 3yrs old when it came to us. The battery box is a large item in the engine bay, but it contained a weedy 225CCA (cold cranking amps) battery that occupied about half of volume - it even had a small booster board under it so that the restraining strap was secure.

    When it failed, as all eventually do, I replaced it with a decent brand 650-odd CCA battery normally fitted to the leccy-roofed Coupé-Cabriolet model, which filled the battery box completely. The difference in price was only about £15-20, but the car started immediately and was generally a lot healthier (no charging problems either). It's not always the case that bigger is better, but was right for that engine, just not factory-fit for that exact hard top model.

Shame, because it was a nippy little thing. It still had most of the older 205-style chuckability, which finally got killed off with the lardy 207,

      Re: Battery box...

      I had a 1999 version of that model 206 1.4LX petrol (second owner). When the battery failed I had no way to get a new battery back from the car parts shop (and wasn't sure it was the battery) so called out Acme Breakdowns to take a look. He fitted a new battery (handily leaving the old one with me). The new one was something like 240CCA replacing the old one with something like 325CCA. Funnily enough from that point it was very reluctant to start cleanly - and I only realised the cause afterwards. My garage had the solution a nearly new 450CCA battery - as with your experience it burst to life promptly when the ignition key was turned from then on.

      As an aside Acme breakdowns refunded the cost of the underspec'd battery which I gave to a family member for use on their boat.

      Joking aside mine was a nice little runner and very few problems in 10 years. I only got rid because the insurance wrote it off after a taxi driver ignored a Give Way sign and drove into it on an icy day.

    Batteries

    I have had two batteries go on me - one on a VW Diesel, which suddenly died at the age of 4, and another one on a Prius, also suddenly, not in winter, and at the age of about 4. My two current batteries are coming up to 5 years old and I'm thinking about pre-emptive replacement - perhaps with the spiral wound ones that are supposed to last longer. The thing is, Diesel batteries have to work hard but a Prius battery is just there, presumably, because Toyota thought it was cheaper than a step down converter would be for the main battery, and has almost no work to do other than keep the lights on for a few seconds after you leave the car.

    With the increase in car electronics, you'd think someone would have come up with a better car battery technology by now. Gone are the days when if the battery went on my Citroen all I needed was a determined hand crank and I could get home without it.

      My Range Rover series A had a starting handle. Even with a low compression head it would have taken an unusually strong person to turn it over fast enough to work. A big rugby playing friend tried it once.

      On the other hand the Mini-Moke was easy. You just scooted alongside it in gear until it fired - then hopped in.

        "Even with a low compression head it would have taken an unusually strong person to turn it over fast enough to work. "

        That was bad design somewhere.

        I used to work with a guy who was in the African desert in WW2. He and two others were sent out in a truck for some reason, and rather cleverly overnight they left the radio on. Come morning the battery was flat, the Germans were supposed to be somewhere around, and they were very nervous. Well, terrified.

        But they decided to read the manual. It gave precise instructions for starting; when it came to the big about "give a strong swing on the starting handle" he said they actually laughed at the idea of turning over a substantial Diesel engine by hand, not to mention the risk of kickback. But they waited till the sun was up enough to warm things a bit, followed the instructions, the biggest one grasped the handle and gave it a mighty heave - and the engine started at once.

        People start marine engines by hand. If Rover couldn't run to a geared starting handle on a 4 by 4 that might need to be started that way, I think that's a bit feeble.

          My late dad's old Lada, about 30 or more years ago had a starting handle. The car itself was of the old Soviet design. Cheap and solid. One or two pushes on that starting handle and it would start.

            Technically, old Italian design. The first Lada (the VAZ-2101) was basically a 1966 Fiat 124.

            In 1966, Fiat boss Gianni Agnelli ("L'Avvocato") brokered a deal with the Soviet Union which resulted in Fiat building a car factory in Tolyatti, a planned city named after an Italian communist, installing British machine tools supplied by Herbert-BSA.

            Unfortunately, the deal stipulated that Fiat was compensated with automotive sheet steel made in the USSR - which turned out to be of such poor quality that Fiat and its subsidiaries ran into massive quality issues that nearly killed Fiat. Hence the adage of Fiat cars already rusting while still just a picture in a sales brochure.

            Well, water under the bridge... by now, Agnelli, Fiat and the USSR are gone - Fiat morphed into Fiat Chrysler Automobiles NV, incorporated in the Netherlands with tax domicile in the UK.

              Re: Terry 6's dad's old Lada

              Yes, 2101 was a licensed production of 124. With minor tweaks. First batches produced in 1970 had FIAT insignias stamped all over, even on boltheads. 1972 model I happened to have still contained lots of components manufactured abroad - Italy, Japan, Yugoslavia, Hungary, East Germany come to mind.

              Bodywork had its own story: for first 4 years, huge rolls of sheet steel were shipped to Sweden for post-processing, then shipped back. Without this extra processing it wasn't possible to punch body panels out of the sheet. Corners were way too sharp for that.

              Jimbopedia has differences between 124 and 2101 mostly covered:

              "Compared to the Fiat 124, 800 modifications were made in all,[5] including to rear brakes (discs to drums),[5] suspension (for higher ground clearance), carburettor, and some other parts in order to satisfy a wide range of Russian climate conditions, as well as thicker-gauge steel (so the 2101 weighed 945 kg (2,083 lb), the Fiat 90 kg (200 lb) less[5])"

              "Early models included a crank, in case the battery went flat (an item later dropped) and an auxiliary fuel pump.[5]"

              But this part about the engine is fishy:

              "first variant was equipped with a 1,198 cc (73.1 cu in) engine (a overhead valve design, never used in a Fiat)[5]"

              All Lada engines have single overhead cam (SOHC) layout, not OHV. Whereas Fiat 124 used OHV and DOHC engines throughout their production run. SOHC engines appeared much later on 131.

        It used to be that as long as the alternator/generator was good, your car would run with a bad battery. Ever since they started putting computer engine/transmission controls in vehicles, your battery has to be the correct size and properly operating, or electrical gremlins will begin to appear throughout the vehicle. Sucks but there you go.

        Optima batteries (spiral wound/dry cell style) aren't as good as they used to be and are more expensive since they moved production to China fyi. A good marine deep cycle battery is now a better purchase.

            My battery is going, so rather than replace it before it is absolutely dead, I bought a RAVPower "car starter" from Amazon. It's a tiny little box, barely bigger than, I dunno, 3 iPads stacked together, in a neat little case. No way is that going to start a 2.0l diesel, I thought, so I charged it up, threw it in the boot and forgot about it. Maybe it'll help my sister in law out when her little 1.0 won't start, and at least I can use it as weekend USB power when away from the mains ...

            Then a friend, who has an older 3.5 V8 Diesel Range Rover, asked me to help her start her car. Left for months, it was totally dead, not even enough juice for the central locking. It was also parked in a corner making it hard to get another vehicle there for a jump start. So, in a talismanic gesture, I whipped out said little box, connected the puny croc clips to the massive battery and did my best to weather the withering storm of contempt, spanning the spectrum from polite skepticism to unrestrained mockery, from the assembled mechanic / farming / military types who inevitably, in a busy rural yard, gather thoughtfully around a very attractive young woman with a non functioning car.

            Honestly, if that little box never works again it was worth the fifty quid just for the reaction from the assembled crowd when the engine roared into life on the first turn of the key.

              It just takes one of the cells to degrade and it'll keep starting the car until the first cold snap (normally when you are late and need to be somewhere) for it to give up the ghost.

                Had a look at these, inside are essentilly monstrously overpowered (20+C) Li-Po batteries.

                The interesting thing is that some of the better ones use ultracapacitors to absorb the initial current pulse which is *just* enough to overcome inertia and allow the motor to turn.

                I also found that like any Li battery they do degrade over time which is why most new units have an expiry date and a health indicator to advise replacement (similar to smoke alarms)

                Not so much of a problem in the cold weather because self heating from high current normally works well.

              550A over these leads? And from a lithium battery? This thing will become dangerous if used for more than 1-2 seconds.

              For a good engine it'll suffice, of course. One guy made a jumpstarter from large capacitors. Worked quite well in extreme cold, but only for a better part of a second.

        Re: Batteries

        Had that here in Alberta recently my Avalanches old battery couldn't cut the mustard first thing on a cold morning (its not called Cold Crank Amperage for nothing). A very nice man from AMA dropped in a new one for an additional $20 (Unlike Crappy Tire who wanted $200), which saved me the hassle of doing it myself.

        I used to have a TR7 back in Blighty that continually needed jump starts, after various batteries\alternators a humping great battery used on Volvos (about twice the CCA IIRC) just about fitted (it over hung) into the battery bay, main reason being the starter motor harness cabling had developed a impedance & there was a voltage drop across the harness from the battery to the starter motor, that was giving the "flat battery" symptoms.

      Re: Batteries

      The best thing I've ever done - and putting some IT back into the subject - was to buy for my own home an UPS with 24V connectors for external battery packs.

      This uninterruptible power supply, curiously, accepted up to 80Ah batteries on the charger, unusually large batteries for a 1500VA affair. In short, a tiny UPS with a current limiter on the charger sized for 80Ah batts, that could be heard humming from the next room. I could use a truck battery and half-inch thick grade cables if I wanted.

      Being 80Ah its limit, I could, in theory, put 2 x 12V automotive batteries in series and this sucker would keep my server running for some 8 hours without a hiccup. I did exactly that with 2 x 60Ah batts, and it worked ever since (remember, they are in series, so each one provides 12V while the charge is limited to the smallest one before a voltage drop-out, so they should have the same capacity).

      The first set of batteries lasted 10 years, which I promptly replaced for another set that would last me to this day.

      The best part of having this setup? I helped friends and neighbours to start their cars countless times, just removing one of the batteries with the terminals and everything, and taking it to the battery-stricken vehicle. Having 2 batteries in a row also allowed a quick comparison of the voltage between them and the voltage of the stricken battery: they should have, at all times, the same voltage and the same behaviour upon disconnecting from the UPS charger. Defective batteries would simply drop the voltage after unplugged.

      In one particular occasion, my own father's battery went pear-shaped, so I was mostly happy to donate one of the batteries to its original purpose.

      Now, about the hand crank: I've seen large generators being started with compressed air instead of a hand crank. They simply keep a compressor and a reservoir topped up on the premises, (along with an oil heater). If the power supply goes sideways, this thing can start a ship-sized 5MW generator in 10 seconds. I suppose we could have something similar for small vehicles... some form of air reservoir, for cold weather places, or a plug that could accept compressed air from an external source...

    Not dead, Just sleeping

    This is nothing new. I lived near Chicago, and some mornings my car wouldn't hardly crank over once... then nothing.

    Two things could fix the issue:

    1. Turn on the headlights for a minute, get some 'juice' flowing through the battery.

    2. Wait until the sun came around the house and warmed the hood of the car.

    On the note of training sessions... training groups of people who work at different speeds is worse than herding cats...

      But at least you could have more fun with the laser pointer if you were herding cats.
