In search of ancient files...

It turns out that my original C programming notes are coming back into fashion. Thanks to the archiving efforts of a site in China (thanks foks) I’ve managed to get hold of the PDF of the notes, but I can’t find the 25 year old original of the document. I’ve spent a big chunk of today turning on ancient laptops and finding that their disks don’t go round any more, including this one above. I think the platter has kind of stuck. Or something. I’m tempted to open it up and give it a tiny twirl. After all, it can’t make things worse……

Good Friday Sounds

Number one son has been buying vinyl. Just like I was doing forty years ago. In celebration we got his B&O system down from the loft and fired it up. It used to be my dad’s pride and joy, and it was wonderful to hear it back in action. The word was that if it didn’t go bang when we powered it up it would probably work fine. And it did. There’s something about proper analogue sound that I really like. Perhaps I’ll get my deck (and all the records) down and have a go some time.

Looping the rowing machine

I’m very proud of this. I’ve “rowed” nearly a 1,000 KM now. I bought the rowing machine a while back and I’m using it quite regularly now as a way of keeping less unfit that I might be.

Gardening

I’m not that keen on gardening. It seems to me that you can spend ages making the garden look nice and then, only a few years later, you have to do it all again.

Sometimes it’s more frequent than that.

The latest re-modelling involves the removal of stuff. I’m quite good at this, although I’m a bit of a blunt instrument and I’ve been known to generate a lot of “collateral damage”. Today I was carefully programmed with the items to destroy and left to it.

Pro tip: If you are removing something substantial from your garden, don’t cut it down to ground level before trying to dig out the roots. Leave a nice long stalk to use as a “handle” to give you some leverage on the stump. I did this, but the person who’d chopped down a whole bunch stuff before me hadn’t. As a result I had a happy five hours digging round the tiny bits left, chopping and sawing roots and using appropriate language.

I’ll tell you one thing though, if you think I’ve had a bad day, the objects of my attention had a much, much, worse one…………

Happy Training Day

Robin and I have spent the day training folks on how to work with the Arduino. We had an attentive and engaged audience and a huge table with lots of hardware all over it and a pile of great food at one end.

Good times.

Flickr Denial of Service Attack

So the Flickr app on my iPhone has just decided to forget my settings and then fail to send me the SMS to complete two factor authentication.

Well played.

CheeseFest Fun

Yesterday we went to Cheese Fest . It was great fun. Not enormous, but just enough going on to make it “Cheese Quorate”. They had other things too, including my favourite name for a purveyor of afternoon snacks called “Game of Scones”.

Being polite pays off

I’ve started saying please to my electronic devices. This is not because I’m super-polite (although I like to think I am). My reasoning is that if you put “please” on the end of a request the device can tell that you’ve finished your command, and that it needs to go off and work out what it means and then do it.

From my completely unscientific testing I’ve found that it does slightly improve accuracy and response. Which is nice. I might start saying thank-you next.

Elvington Birthday

Went to the Yorkshire Air Museum today to celebrate a family birthday. Great place to visit.

Not an April Fool

What with things the way they are at the moment, I’m surprised anyone bothers with April Fool pranks. Instead, here’s a nice picture I took in Germany a few years ago.

Train User Interfaces

We went to York Railway Museum today. Two of my favourite attributes. Free to go in and full of trains.

I found all these brightly coloured controls in the front of a large Chinese locomotive. I hope that all the taps do the same thing, otherwise this is an accident waiting to happen.

Be one of the Millions

If you feel strongly that Brexit is a bad idea, and should be stopped, then you could sign up at this petition. I’m not sure if it will do any good, but five million (and counting) people can’t all be wrong, can they?

Drain Unblocking Etiquette

Truly an amazing device

Arrive home on Valentine’s Day to hear the three little worlds that can change your life: “The toilet’s blocked”. Oh well.

The thing with tools like drain un-blockers is that you can only find them when you don’t need them. And so it was on this occasion. Fortunately we have awesome neighbours who are much better at keeping track of their stuff than we are. They were able to lend me a device like the one above. It really is wonderful. You pump air into the reservoir and then release it into the blocked pipe using the trigger. After a couple of blasts we were good to go. And all in time for tea.

What with me being so flushed with success (as it were) I kind of lost track of the fact that I’d borrowed next-door’s sink un-blocker and stuffed it down our toilet. I’d washed it carefully and all, but still….. So it was on to Amazon to track down a clean replacement. It arrived today and I’ve dropped it round. Now, between us we can just about handle anything.

Back in Harness

One of the things I really miss about working at the university is standing up in front of people and telling them stuff. I’ve tried it on busses and trains and it just doesn’t work in the same way, what with the shushing and the telling me to sit down and shut up.

But in a week or so I’ll be back at the university for a short run, talking about digital electronics. I’m doing a bit of teaching for the Mechatronics course and I’ll be regaling an enthralled audience with tales of boolean algebra, De Morgan’s Theorem and Karnaugh (first name Maurice) Maps.

I’m going to enjoy it, I’m not sure what the audience will think…..

Buying train tickets is harder than it should be

I hate it when things make me feel stupid. Buying train tickets online seems to be one of these situations. I wanted to buy some tickets to go from from Hull to London on Saturday. My normal approach (use the phone) was thwarted by the error message “Ooops. Something went wrong” when I tried to complete the purchase.

So I headed off to the web. And was met with the above. This is the page for Hull Trains, but lots of companies use the same UI, so I’m not happy with them either.

Questions abound. Why are the prices not shown? What do the buttons on the top actually mean? Why is the page called a Mixing Deck? And what on earth happens when you press the “Lowest fare finder”? Ugh.

After a bunch of experimental clicking and tweaking I finally managed to select the same trains that the phone wouldn’t let me buy. And I was told that there were no tickets available at that price. So “Ooops. Something went wrong” actually means “I’ve told you about some tickets that aren’t actually available".

So, train people, just a word here. When I go to a site to buy some tickets I want a list of journey options with a price next to each one. And I don’t want you to show me journeys that, for marketing reasons, you’ve decided not to sell me any more.

Assertiveness Level Up

After my “success” negotiating my car tyre price last week I’ve now decided to stop apologising in shops when they ask for a store loyalty card and I haven’t got one.

Negotiator Rob

Sometimes I manage to surprise myself. Like today, when I was buying some new tyres for the car:

BMW Sales Person: Names Price
Rob: Names Lower Price
BMW Sales Person: “I’m afraid that would mean we’d have to sell you the tyres at cost price.”
Rob: “Hmm. I can’t see a problem with that”.
BMW Sales Person: “Yes, but that would mean that we would not make any profit on the sale.”
Rob: “Still searching for a problem for me, still not finding one”.
BMW Sales Person: “OK then”.

Now, I realise that “cost price”, is an interesting phrase, and that somehow the garage will be making money on the deal. But at least I didn’t take the first price that was offered. And for me that is a great step forward.

The Virtues of Virtual Machines

I spent a chunk of today building a brand, shiny, new, Virtual Machine on my PC. Each time I do this I’m impressed by how easy it is.

I want to record some installation videos and I want a clean machine to do that with. Also, it’s wonderful to be able to wind back the machine to pre-install state so that you can have another go.

I had to work quite hard to get the machine to let me create a local user, and not link up to an online account, but it is still possible to do this.

Achievement Unlocked: Sofa Mended

What with today being the start of a new month, I thought I’d do just one of the things I thought I’d get done last month.

I’ve mended the sofa.

This just required a bit of patience, a sharp screwdriver, a big bag of stuffing, and a staple gun.

First step was to take the sofa to pieces and then unstaple the cover from the frame. It turns out that a sofa that looks like it has three separate cushions is nothing of the sort. Once you’ve undone the cover you can just peel it back and take a look at the cushions. In my case it was simply a matter of putting some more stuffing on top of the cushion that was getting a bit tired and then stapling the cover back into position. Although I did also have to replace some of the webbing straps as well, cue for more staples.

If you’ve got a sofa that is going soft, it does seem to work as an approach. And I’ve got a lot of stuffing left over which I’m not sure what to do with. And I don’t want any suggestions….

Fit Family

I’ve started taking keeping fit a bit more seriously. I’m using my Apple watch to track my efforts and I’m trying very hard to make sure that I “close all my rings” each day.

Let me explain. The Apple fitness system (to which I am now a slave) measures three parameters each day: how many times you stand up, how much you move and how much you exercise. You get targets for each of these and during the day a growing arc is displayed that represents your efforts. When the arc closes on itself you’ve “completed a ring” and can go back into couch potato mode.

The stand goal (of 12 stands a day - one per hour) can be a peculiarly tricky one to hit. Too much lazing around early in the day can result in you having to stay up to 11:00 pm at night just so that you can get the final stand in. The watch goes ping at 10 minutes to the hour to tell you to stand up at least once (it’s scarily surprising how often I have to reminded to do this) but if you’re deep in a piece of code you can easily miss that.

Recently other members of the family have linked their Apple fitness regime to mine, so that we can compare our progress. This is going quite well, if only as an instructive lesson on how devious people are at “gaming” a system. One member of the family has adjusted his “move” target to a level where simply getting out of bed and raising one eyebrow will count as a days’ worth of activity. Another has discovered that you can start a workout (and thereby gain exercise credit) at any time, which allows time spent watching athletics on telly can be made to count as keeping fit. And I have perfected a sequence of arm waving that works beautifully in convincing my watch that I’ve stood up and taken a walk.

I guess this means that we are all now “lab rats” dancing to the tune of a faceless corporation.

But at least we’ll be slightly fitter lab rats.
