    Upsetting non-techies can be hard

    My old Fluid Dynamics lecturer used to tell the story of his time testing aircraft models at the Royal Aircraft Establishment as an example of how geometric similarity (all dimensions exactly scaled down in models) and physical similarity (model should produce the same aerodynamic results as the real thing) were very different.

    He used to be presented with beautiful models in velvet lined cases by master machinists, whom he would then profusely thank...and promptly get out the sandpaper to roughen up all the leading edges: the flow behaviour was otherwise unrepresentative. On the occasion of one of the machinists seeing the model in the wind tunnel, he was quite upset!

      Ahh yes, sandpaper and shiny surfaces. I can say from experience it hurts a little deep down if you're the one doing the roughing up too.

        Re: Upsetting non-techies can be hard

        I am reminded of the time a lawyers' office decided to try and speed up their secretarial work, by getting the lawyers to do some of the text processing themselves. Given that they had an office full of luddites and two-finger typists, this was a non-starter until someone had the inspired idea of using speech-to-text software. Most people had their own private offices so noise wasn't an issue.

        After initial training of the software, everything seemed fine. The senior secretaries found the system effective, but some preferred typing. The lawyers were more of a mixed bag. Sometimes it worked, sometimes it didn't and no amount of training changed this. Until a pattern slowly started to emerge...

        Failures to recognise speech were much rarer in the mornings and late afternoons, and commonest right after lunch. Eventually the fault was discovered to be that whilst humans can understand almost any other accent best out of three, machine speech recognition software really struggles with "Lawyer after lunchtime drinkies".

        Short of training the system on lawyers both sober and tipsy and thus having to admit that lawyers drank physiologically effective amounts of alcohol over lunch, there was very little that could be done, and eventually the matter was dropped in favour of trying to teach lawyers to type.

          Lawyers and speech-to-text

          There was a senior partner at a law firm in Edinburgh in the mid-late 90s who didn't bother with the typing pool. Used Dragon Dictate with a long cable on his microphone so he could watch the world out of his office window. It did a great job too - he was delighted.

          One day we upgraded him to Dragon Naturally Speaking, which would process fluid speech, rather than having to halt briefly at each word. (He was very practiced with Dragon Dictate, so this style of speech was no problem, but newer is better and all...) It choked every time he said 'notwithstanding', which (as a solicitor) was rather a lot. Every time it would enter 'not with standing'.

          Took a week before he gave up and went back to Dragon Dictate. Until he retired, to my knowledge.

          I understand the minutes of their monthly partner meetings became quite hazy part-way through. And don't bother trying to get anything near the end of the agenda actioned...

            There were and are too f-ing many bits of Windows that do this. Stuff happens, because a random key combination gets knocked and there is no visible way of getting things back to normal. Ideally there ought to be a button that reveals status of various options, so that users can see what has been set.

            BUT, mostly the real problem is that Help in Windows is and has always been total crap. Usually if you go and search for anything unusual that's happening it won't actually be mentioned. These are settings ffs.

              You can always make a God Mode folder, which gets you close to that.

              Create a new folder on your desktop--or anywhere you'd like--and name it: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}. Don't include the final period. The resulting folder will contain 270 items, representing virtually every configurable option in Windows.

                  So-called "GodMode" has been around since 2006 or thereabouts (when Win7 was in pre-Beta). It has been one of the first things I do when forced to evaluate a Win7/8/10 system[0] ... or when blackmailed into fixing a b0rken one. You can change "GodMode" to "HideThisRedmond" if you like.

                  Note that Win2K and Vista have their own variation on the theme, which is why I went searching for it when Win7 came out in pre-Beta.

                  [0] Can't sell a FOSS system to CorporateAmerica unless you can thoroughly debunk the Redmond marketing hype with facts ... it's not that I don't know how to use Windows, it's that I really, really don't like the way it does things.

                  I find the biggest problem to be the glued-together piece of crap that is settings on Win10. There's there Settings app, in which individual settings are in the most bizarre places (notifications are in "system", app permissions are in "privacy" instead of in "apps"). Then there's still the old control panel we know and love, with a few things removed, or even still there but disabled. (startup in msconfig is now in Task Manager, but with the tab still there and a helpful link - why move it then?)

            Re: @Dan Holdsworth

            Have to agree with Nick Kew here. Two reasons why:

            1. A friend of mine has some severe hand problems and as such, before she was diagnosed, typing became a real problem. She invested in Dragon NaturallySpeaking (DNS), and in fact is now a premium dealer for Nuance (who make it) because of her extensive expertise in it (and everything around it). She deals with lawyers a lot, and they seem to have similar issues (mostly morning or really late evenings). She hersef has said that when she gets tired, DNS doesn't quite understand her and she *really* has to work hard as clearly enunciating her words to get it to recognise what she is saying.

            2. I used to have to transcribe interviews a lot, often late into the night after a long day on a race track. Following my friend above's advice, I invested in DNS and during the day (the day *after* an event), the transcription would be ok, but after a long day? Forget it. It would truly make a hash of it. It was mostly the inflection that changed sufficiently for DNS to understand slightly different words (not garbled, but slight misunderstanding), which in the end turned out to be more work to correct than the original typing I did. So... just like the lawyers, I canned that investment. :-/

          A lawyer I know was working on a case years ago involving technology. They hired an expert to help explain the complex nature of the case in court. The case was to do with the security of WiFi and how something might have been intercepted. The expert they were using was a new one because the previous bloke had "blotted his copybook". Apparently he was asked in a meeting how far away we were from 100% accurate voice recognition and he replied "By the year 2000 people won't be using a physical keyboard anymore you'll talk to your devices.

          Well the millennium arrived and this was still not even on the distant horizon so they gave him the elbow. That and the expert on the other side in the case had proved to be a more expert expert and had virtually won the case for the other side.

    Noisy phone lines in building

    While I was fixing specific things in West Africa, I would always try to find if they had any other problems I could fix at the same time.

    Turns out the phone lines were noisy. I checked our internal cabling.. all fine. I then looked where the cable came into the building, about 2 m from where the cable landed from the pole. However that was not the route the cable took.

    It went all the way around the building, with countless "expert" joins (the wires kind of twisted together). Some of them even had tape on!

    One proper join later and the cable length had been reduced by a good 2-300 m, and call quality significantly improved.

    Pint because I deserved it going up the REALLY dodgy ladders.

      Its more obvious with Ethernet.

      At a company where I used to work, they were moving machines in one of the manufacturing areas, and they didn't tell us (IT) beforehand. After they'd been moved, they called and reported that their network connections weren't working. We asked for and got the line numbers from the jacks, and after suiting-up and entering the clean room, we discovered that the cables no longer terminated where our database said that they did. After calling back, we were able to find where they'd move the equipment. We tested the lines, and while they had patched them correctly, they shouldn't have patched them because they added 100m to each of the cables taking them well over-spec, and making them completely unusable for anything other than analog telephones...

      This was one of the events that ended up with IT working more closely with building engineering to prevent this type of screwup in the future. We provided them with some guidelines like:

      no cable runs over 100m

      if you can't reach a wiring closet in 100m it means that you're in new territory and we need a new closet

      cables should only run towards the destination wiring closet, even if that means a new hole has to be drilled in the ceiling

      no splicing of cables

      if you move jacks, you must tell us

      We had it down to a science. We'd test and label every cable on installation and unless there was a suspected fault in the wiring at a later date, we totally eliminated having to use a tone generator to locate cables. This was a huge cost-savings since it meant that 99% of issues could be resolved by a single wiring tech in a single trip; whereas previously, it took two techs and a tone generator before anything could be fixed.

        Re: Noisy phone lines in building

        It is possible to make sure they tell you when they change things.

        I gave the fitters a dump of the data table that told the controlling computer which ports did what in the machine they were building. When they changed the wiring on-the-fly they could copy the table into RAM, use the machine code monitor to edit it, and blow it to a new EPROM. They could then write the amendments on the print-out so I knew what had changed.

        I explained that each time I gave them a new version of the code I would first come and get that print-out and copy all the changes they had written on it into the new version.

        And that if they had missed writing any changes it was Not My Problem when their machine no longer worked.

        They were very careful, and didn't miss any.

        Re: Noisy phone lines in building

        Ahh the problems when people don't take into account cable lengths. Couple of years ago we had some major building work done at one of our sites. As part of this, they shifted the access gate for the car park and planned to move the security hut (small building with a couple of PCs and IP phones in it). Everything was planned to shift the hut and have a cabling firm in the same day to run new data feeds.

        Except that later that day, the site called to say that the connectors looked different. Upon investigating, the old location for the hut was 80m from the nearest comms room, so just had a couple of lengths of CAT5e run to it. New location is 125m away, so the cabling firm ran a fibre feed instead.

        And of course, nobody had budgeted or planned for an extra switch. The hut was without phones and PCs for a couple of weeks whilst everyone scrabbled around for more budget to purchase a switch and fibre GBIC for it...

        I would add a couple of comments.

        You don't move jacks, you add some at the new position when it is needed. The old ones should remain untouched as they will be used very soon by the new user of the premises.

        IT is a support service, like finance is. No department would think about running their own finance, why would they run their own IT? Network infra belongs to IT and can only be managed/maintained by IT.

      When I started at a previous company as IS manager the DP Manager, who became my junior, had previously had a free hand at IT. We still had mainly dumb terminals on an AS/400 connected via Twinax (it ran from the concentrator then terminal to terminal with a terminator on the last connection). No real problem, except that every time a new terminal had been added he'd simply run two new cables from/to the nearest two terminals even if they were across the room. The end result was that the cable runs in the main office zigzagged across the floor.

      It took about 20 minutes after hours to recable the entire office so that the runs went down each side. I've hated cable covers in offices ever since!

        Re: Noisy phone lines in building

        Here's an old post of mine from 2009, originally titled "That's just the switch, they do that!" ...

        The scene: Old house in Mountain View, converted to Vet clinic.

        The time: Late 1999.

        The job: Convert the Vet's database from non-Y2K compliant PSI/Idexx on HP/UX to Cornerstone on Win98 (I know, I know, but that was what the Vet wanted).

        Considering that Cornerstone included the database conversion in the cost of the 8 hour staff training session, my job was basically setting up the Windows boxes, installing software, and pulling wire. Easy. In fact, I did the complete network setup back in my lab, so all I had to do was make space for the computers, printers, label makers etc., plug it all in, and turn it on.

        Unfortunately, the house was built in the post-war building boom, and originally had 2 prong plugs for mains power. Some had been converted to three prong, but not all. I had to convert the six locations where the Vet wanted the computers installed. Three new breakers, pull some wire ... Again, pretty easy.

        Day of install, the Saturday afternoon before the Sunday the Cornerstone rep was to hold the staff training session. The Vet wanted me to plug a scanner into her personal machine. The floppies that came with the scanner didn't come with Win98 compatible drivers, so I used the new-fangled V.92 modem to dial into my ISP ... But the connection speed reported as 2400 baud instead of the expected 56K (or so). I broke the connection, redialed, same result. And again. Now, I had already used the modem from my lab, just to verify it worked, so I knew it wasn't my hardware ... I picked up the phone. Line noise. 60hz line noise, to be precise.

        I turned to the Vet and asked how long the phones had been buzzing ... she brightly answered that "That's just the switch, they do that!" ... WTF? After further questioning, it turned out that instead of having six phone lines coming in, she had a small switch with six extensions. It was installed when she took over the practice about a decade earlier. (You can probably see where this is going ...).

        She lead me to a storage and washing machine room in the back, and pointed at the wall. Hanging there was a dusty, cobweb covered, slightly sad looking $TELCO supplied switch. It had a three-prong cord ... plugged into a two prong socket. The $TELCO tech who did the install had cut the ground pin off the power cord to fit the availabe mains power. I asked her to go get me a cordless 'phone and grabbed a wire coathanger. With phone to ear, I grounded the case of the switch to the cold water pipe with the coathanger ... No more AC hum.

        I explained the situation to her, and she went ballistic. After she calmed down a little, I asked if she wanted me to call $TELCO for her. (I could have put a new cord on it myself, and put in another 3-prong socket, but if you touch $TELCO gear, they will refuse to fix it if anything goes wrong in the future.) On further questioning, she allowed as to how in the last decade she had had techs out half a dozen times or so to service her telephones, including what sounded like a firmware upgrade to the switch itself.

        Long and short of it, we had a $TELCO tech out 45 minutes after I hung up the phone.

          Re: Noisy phone lines in building

          This sounds like a bigger nightmare coming with the old wiring and cut-off grounds. We purchased a house that had wiring like that and we hired an electrician to update the wiring for us. After pulling about 10,000 feet (not exaggerating) of dead lines out of the ceiling, and finding some cut-off live ones too, we're finally safely wired up. That wasn't all. To add insult to injury, the basement wiring was a single lamp cord wired to the wrong side of the fuse box!

          But the telephone issues were interesting. When we first moved in, we used modems for internet service. We would dial out only to be kicked back, as you noted above, from 56K to 2400, or other times we couldn't get out at all. One day while the modem was dialing, we heard a local radio station interference on the modem! We called the local phone company office and the tech came out and did something on the pole to fix the problem, which I don't recall. In the end he said that it didn't surprise him, and was shocked that we got anything to work at all given the age of the phone lines in the city.

        One of our worker bees came to me with 60Hz interference on his CRT monitor. Different monitor didn't help. Could not find the source. He didn't have anything that would generate interference like that.

        I guess I finally beat my head against the desk enough to shake something loose in my brain, because I suddenly remembered that the main distribution box for that entire floor of the factory (...ok, half of it) was on the other side of the wall that end of the desk was pushed up against. Well... Technically it was inside the wall, of course. What was in the corridor was just access. But you get what I mean.

        A quick test confirmed it. Next morning I reported the diagnosis and the victim happily rearranged his desk in mirror image. Problem solved.

        It only took two monitor swaps and three nights of frustrating diagnosis.

          One of our worker bees came to me with 60Hz interference on his CRT monitor

          Had a couple of those (albeit 50Hz in the UK).

          First was most of the CRT terminals (Wyse 60) in the accounts dept with shimmering screens that all came/went at random times. I guessed magnetic field and asked the sparkies if they'd been doing anything recently. Turns out they'd been working on the sockets ring in the shop downstairs and a wire has slipped out of one of the terminals. Result was that when the electric heater came on, the live current went two ways round the ring, but the neutral current went one way - creating enough field to affect the CRTs. Finding the loose wire and fixing it banished the problem.

          More entertaining was when they were extending the offices - steel frame that was bolted and welded together, and I bet some of you are ahead of me already. They'd just stuck the welding earth clamp where it was handy and were roaming around welding the joints - thus creating a rather large and complicated network of steelwork carrying heavy duty welding currents and thus creating magnetic fields. The effect on the CRTs (still Wyse 60s mostly) was "quite interesting" to say the least - enough "shimmer" to take the image completely off the side of the screen !

            A process plant a friend used to work at suffered more serious effects. During a shutdown the welders extended the steelwork and also didn't bother to attach the earth clamp close to where they were welding. The resulting stray currents burned out a rack of instrumentation and the start-up was delayed by a few weeks, at a cost of millions of lost production per day.

          I had that issue as well caused by an elevator (lift). The office admin's desk was located just to the side of the elevator and every time the elevator was called, and the motor kicked in, her display would wobble and bounce. It was interesting to watch, but probably annoying for her. We moved her to the other side of the lobby and away from the motors and that solved the problem. The phenomenon was quite fascinating actually and made me wonder white kind of effects the EMF was having on other things around nearby beside her NEC monitor.

          Having worked with CRT video terminals in the past, I saw a rather interesting thing with displays not mounted properly in the chassis for the destination country. Due to the earth's magnetic poles and pull, the image on the CRT can be off kilter if, for example, the image is aligned for somewhere in the Northern Hemisphere, but the display is sent to somewhere below the Equator. The good thing is today this is all obsolete due to CRTs going away and being replaced by LEDs. Still way cool how the magnetic fields can affect them.

      Re: Noisy phone lines in building

      We once had our group moved to a trailer while renovations were being done. The image on some of the computer monitors would jitter. It seems that there was a 60 Hz magnetic field causing this. I built a coil of wire, amplifier, attached earphones. Finally discovered one of the fluorescent lights had switched the neutral and ground and that there was about 5 amperes of current running through the safety ground. Fixing that solved the problem.

      The site electricians found out about the device and wanted it so I gave it to them. Very useful for tracking buried power wires.

    Falling on hard times

    A young engineer (not me) was working on microwave propagation and got permission to work in a disused section of an old part of the site on the second floor. It had lots of empty space over long distances and he could move stuff if it was in the way and so it was ideal for his work.

    He needed a strong sheet of wood to set up a bench and had noticed a large old interior-grade wooden door lying on the floor so he decided to lift it and move it and use it. He was careful to bend his knees and not his back, etc and he lifted, shuffled and pushed the door towards where he wanted it to be.

    A short time later, he fell through the hole in the floor that the door had been covering.

    I have learnt the hard way, that if you're opening up and old computer to give it a clean, it's best to take it outside first, if possible.

    Breaking out the canned air and blowing chunks of dust throughout the entire office will not make you any friends.

    Oh, and while we're on the subject of cleaning, take my advice and treat keyboards and mice as consumables and just hand over new ones when they get old. Other people are disgusting, filthy, animals when it comes to what they'll do on and around their keyboards *shudder*.

      Remember the old cans of cleaning solvent marked "non-inflammable"? The senior tech when I got started in support used to demonstrate them with a match in front of the can - shooting a stream of flame halfway across the room.

      His lesson was that the solvent was non-inflammable ... but the propellant wasn't. It's not a lesson that you forget.

        Well, "flammable" means "easily set on fire" so the double-negative "non-in" still means "easily set on fire"!

          "inflammable" and "flammable" both mean the same thing, so "non-in" in this case is not a double negative.

            Either it flams or it doesn't, simples :)

            Actually the proper word is inflammable but some safety people thought that sounded like "not burnable" so they coined the word "flammable".

      Yes absolutely spot on here!

      I had splits in my fingertips from using antibacterial goop on my hands when I was working from cleaning my hands after working with user's PCs. Yuck is beyond describing that. I've since retired and don't miss that!

      Oh to save a few bucks/quid, get a Rocket. They're about $20.00 US on B&H or even Amazon. It's a squeeze-bulb in the shape of a rocket and it's a lot cheaper in the long run and nicer for the environment too. I've got one and it does a nice job getting the dust clumps out of fans and the crevices inside the case.

      Definitely do this outside as you recommend.

    Shouldn't Jason have been one for Monday's column?
