A funny thing happened on the way to the toilet…

Warning: Technical detail ahead! If your eyes start to glaze over, skip to the end where there are some links to videos. 🙂

I had one of those weird experiences this morning where lots of technology and mundane basic things bump up against each other. I was on the way to emptying a full potty when my mobile phone rang in my pocket. Yesterday I had the afternoon off and just as I was leaving a minor crisis blew up so I forwarded my work phone to my mobile in case anyone rang me about it. The colleague who rang me didn’t realise this, called my extension and got through to my mobile.

This was all complicated by the fact that he was phoning from India (he’s Indian) and the large American company for which we work has made the phones in India use VOIP, plus plumbed this in so that they appear as American phone numbers! While I was talking to him, I was trying to work out what route the call was taking, and this made my head spin. I think it was like this:

  1. My colleague’s extension talked to his local switchboard.
  2. The switchboard realised it was an external call, and so handed it over to the company VOIP network.
  3. The VOIP network carried it from India to America, which involves crossing the Pacific Ocean by undersea cable or satellite.
  4. In America, the VOIP network pushed it out to the local phone exchange.
  5. The local US phone exchange realised it wasn’t a local call and so it went up to the nearest US trunk exchange.
  6. The trunk exchange saw that it was a UK call and so sent it over to the appropriate trunk exchange to go over the Atlantic Ocean.
  7. It crossed the Atlantic via undersea cables or satellite.
  8. When it arrived in the UK, it travelled through the UK trunk network to the local exchange nearest to my office.
  9. The local exchange sent it to my office’s switchboard.
  10. My office’s switchboard put it through to my extension.
  11. As call forwarding was set up on my extension it bounced back to the switchboard.
  12. The switchboard dialled back out to the local exchange.
  13. The local exchange realised it wasn’t a local land-line call and so sent it to the nearest trunk exchange.
  14. The UK (land-line) trunk network worked out it was a call to my mobile operator’s network and so pushed the call over to that network.
  15. The mobile network looked up the last base station that my phone had registered with and routed the call through to that base station.
  16. Electro-magnetic waves travelled from the base station to the phone in my pocket!

It all just worked! (If, instead of being at home, I’d gone to France it would have been even more complicated, but it would still have just worked!) My colleague didn’t need to worry about anything more than my phone number – not what kind of phone he was dialling, what kind of network it was attached to or anything.

The reason why it all just works is largely due to standards for phone networks, as governed by the ITU, which is part of the UN. Because of the standards, each part of the phone network involved needn’t worry about anything further than the next step in the journey, for instance the Indian switchboard just said “VOIP network: you deal with it”.

At work we put some of our software on top of something another company sold to mobile phone operators, which meant we felt the sharp end of the ITU standards. (The mobile phone thing looked like nothing more than a large computer to our software.) Our software had to, come what may, produce an answer within so many milliseconds of CPU time otherwise the thing expecting our answer would just give up and assume the answer was “no”.

All this amazing leaping across the world is brain-boggling enough, but that’s just looking at things from the point of view of the phone network. If you dig down into lines of code running on computers, or logic gates in the chips on those computers your head starts to overheat! It’s a bit like the excellent powers of ten film from the 70s (or the more recent versions by The Simpsons or Men in Black).

Set the control to ‘Romans’

When I got home from work today, Doris and clan were still around having tea with our lot, which was a pleasant surprise – apparently a good time had already been had by all visiting the Zoology museum, chatting and taking part in a study on child development (just our lot) – the Zoology museum was handy for the bit of the university doing the child development work which was handy as we’d managed to double book things. Thanks Doris et al for being flexible about this!

I half unpacked the mail order box I’d brought home from work while the hordes ate, but due to some urgent interruption or other didn’t finish it. (It would be nice to have an increased percentage of jobs that get finished in one go, but I think that’s known as having retired.) The next time I went back to the box J had completely unpacked it in a random, fling it around the room, kind of way as he obviously wanted to turn it into a time machine. It now has a detachable control that looks a bit like a speedometer, labelled “Romans”, “Other” and “Home 2006”. Guess who likes reading daddy’s old Calvin and Hobbes books?

This is the first bit of web stuff (and first post) done via the new broadband provider and our computer. I’ve previously cheated and used the new broadband with my laptop temporarily home from work, but this proper set-up involves a looooong extension lead between the micro-filter and the modem – and it works! The furniture shuffling to get the extension lead in place wasn’t too painful, so I know that if my current job comes to naught I could always try pulling cable for a living. Yes, I know we could have gone for wireless, but life’s too short to worry about securing the thing and we haven’t had noticeably diminished lives through not being able to check email on the loo.

Nice conversation with K while getting him ready for bed about echoes, ultrasound, bats and aeroplanes’ radar.

Pimp my blog

Inspired by the selection of smilies over at Making it Up, I’ve expanded the range of smilies on this blog (by pinching theirs). So, if you’ve been frustrated that you couldn’t put a little waving person or a Pacman drinking a pint of Guinness to express yourself properly, your day is a little nicer.

In case you’re interested (and you’re able to fiddle about the innards of your blog, and your blog is powered by WordPress) here’s how to do it.

  1. First, catch your smilies. Do this by visiting them in your browser and doing Save Image As, which is probably on the menu you get when you right-click. Save them to your hard disk.
  2. Put them onto the computer that hosts your blog, into the wp-includes/images/smilies folder, where you’ll already have things like icon_eek.gif.
  3. Take a copy of wp-includes/vars.php, just in case things go pear-shaped.
  4. Edit vars.php. Scroll down a bit and you’ll see an obvious list that shows smilies or magic text going to a .gif file. Add to this list so that new magic text goes to the new .gif files.
  5. Test it out in a new post. If you’re happy you can get rid of the back-up of vars.php.
  6. Smilie-tastic! :clap:

I’m the Dandy Highwayman

Today I experienced a blast from the past because a colleague lent me some music, which covered a wide swathe of my youth from my very first music purchase up to college days. First: Adam and the Ants greatest hits! I was listening to it on my headphones while wading through someone’s document that needed reviewing. My boss, who sits next to me, looked a bit curious as to why a schema change request should make me smile so I told him what I was listening to. He’s about my age and a big classical music fan, but even he knew to cross his arms across his face in true Ant style, which compounded my smile.

Then there was some Cocteau Twins that was so beautiful and brought back such lovely autumnal memories that it nearly made me cry. Oh and some Siouxsie and the Banshees and … I did get some work done, honest!

It still surprises me how much music can be a set of coat hangers on a clothes rail for the rest of your life. It’s like a filing system – “I was listening to X when I did Y” – and a much stronger or more pervasive linking than “I was wearing X when I did Y” or “I had hair style X when I did Y”. I wonder what music our children will absorb into themselves. Currently it’s stuff from our music collection, plus Veggie Tales. I can imagine them in the old folks’ home in many years’ time, joining together in a rousing “If you like to talk to tomatoes; if a squash can make you smile; if you like to waltz with potatoes, up and down the produce aisle…” and getting confused over the lyrics to We Are The Pirates Who Don’t Do Anything (which are rather confusing).

Phew!

Katy will possibly write about this at more length later, but a brief post from me. This afternoon, K, L and Katy were models at the inaugural baby show staged by the local NCT. We went to the venue yesterday to pick up the children’s (gorgeous) clothes and to find out what we to do – no problem until L threw a major strop because she didn’t want to take the nice clothes off at the end of the practice. Huge sports hall with very few people about, so that those who were had no trouble in seeing or hearing us wrestling her out of them. 🙄

This morning I was in the shower when L came into the bathroom and said “I got a beard!” As I hadn’t got my glasses on I couldn’t see well enough to make the beard out. My heart sank as I thought she’d got hold of a black felt-tip pen and scribbled all over her face, which would have been a lovely surprise for the lady whose clothes she would be modelling. K had come in with her and so I asked him what she’d made her beard out of. “Porridge” he said (it was after breakfast). Phew! I was very glad that L had a porridge beard, which isn’t something that happens every day!

The show itself was well run and so on and the venue was good – the normal sports hall floor had been covered up with carpet, so it felt like a proper exhibition centre, apart from the cricket nets and basketball hoops around the walls. J got to take some more photos with the digital camera, some of which came out very well.

Home archaeology

We’ve had the windows at the front of the house replaced – they were single-glazed, with rotting wooden frames and cracked glass in places. Katy took the children out for the day yesterday to a local park (not the neat flowerbeds kind, more the trees and long grass kind) with a couple of other families, and off to London to do a couple of museums today.

When the downstairs windows were removed the fitters discovered a scrap of newspaper stuck in the frame. It was from Farmer and Stock-breeder, Christmas 1958! (Unfortunately it’s unlikely to appear as the guest publication on Have I Got News For You? as it isn’t in print any more.) I asked them if they’d mind putting a fresh bit in with the new windows and as I didn’t have a paper they put in a bit of theirs – front page of yesterday’s Daily Mirror, featuring Richard Hammond’s first interview since his accident. Not sure what future owners will make of that!

Upstairs they discovered the weights and other bits from the sash windows that were in before the windows they were replacing. As the previous windows’ fitters hadn’t removed the sash windows properly there was some wood rotten enough to push your thumb through…

Museums, Masks and an Outbreak of Blue

Saturday was one of those weird days that had bits that were so different from each other that it’s hard to remember them as the same day. It started terribly – everyone seemed very tired, short-tempered and bolshy. Going out with the children rather than attacking the mountain of jobs didn’t appeal to me, but I’m glad that Katy’s common sense prevailed over my bad mood.

Despite the setback of lack of scanner we got the children’s entries off to Nature Detectives OK due to noticing on their web site that it was alright to post them over the weekend! 🙂 Because the morning grumpiness had raged for so long, we only just got to the post office in time, and then got into town in time for lunch. When our local Woolworths turned into yet another Next, the only decent cafe where you can get something simple but good like a baked potato is in the library. There are excellent views over the roof tops of the historic buildings, but there are two problems: washing up is limited to wiping the trays, so everything else is thrown in bins. Also, due to the huge new shopping centre development (to add to the two existing shopping centres and the slightly smaller shopping centre development happening just across the road), the whole library will be shut for OVER A YEAR very soon :-x.

Over lunch J asked why Turkey and Greece don’t like each other – I think this carried on from something else we’d been talking about recently. We said that they had invaded each other over the years, and generally vied for being Top Nation like France and Britain had. I told him about France and Britain competing over whether the meridian should go through Paris or London, which led to a discussion of what a meridian is.

Katy also said that Turkey vs. Greece might be due to Christian c.f. Muslim, and how this is an excuse for some people to be violent. We said that Jesus didn’t tell his friends to invade other countries, but to love each other. This wasn’t the same as being weak – he got angry when people did things wrong, but he kept people and the bad things they did separate. Katy said it was like the Nestle boycott – we don’t like what they do and get angry, but we don’t bomb their factories. We wrote to them and won’t give them our money by buying their stuff until they stop. I write all this now as it’s mostly to show how our discussions with the children are often interesting to us and go over unexpected things that force us (me, at least) to test what we believe in.

The reason for our expedition was a special event at the Archaeology and Anthropology Museum, about faces and masks. I’ve been to other departments and their museums, but none of us had been to Arch & Anth before. In short, it was excellent! J said it was his favourite museum, replacing his previous favourite which was the Science Museum in London. Mostly it was the staff – there were extra staff specially for the day, who really were interested in the children and respected them and wanted them to enjoy themselves. It was linked to the Big Draw, and the first thing we had to do was to draw a smiley face on a circle of card so that we could stick it with some blue tac to the exhibit we liked the best. After a bit of wandering around looking at interesting spears and spear throwers, bows and arrows and things dug up locally we got to someone inviting us to draw faces on big paper cups, which quickly became prosthetic ears.

Then the children made masks, and printed faces using stamps that were copies of art from the around the world. Plus there were loads more exhibits: a three storey totem pole, a huge grizzly bear totem pole, samurai armour and sword, mongolese shaman costume, a statue of the goddess of mercy (lots of arms), a statue of a buddhist sage, a huge ceremonial food dish carved out of wood with huge ducks and dolphins for handles, an innuit qayaq (not spelled kayak) next to a polynesian canoe, native american clothes, innuit fur clothes and boots, and an african mask with a face at the back as well as the front. It was labelled a Janus mask, which prompted discussion with J about the god Janus and when I said that was where the month January gets it name from, J remembered Thor giving his name to Thursday. We bumped into a few families we knew which was nice, and Katy had a chat with another mum over mask making about schools and home education.

A Maori sculptor made lovely huge clear acrylic set of carvings, lit up beautifully. He had full body and face tattoos, and a (maori) kilt, and drew maori face tattoos onto a paper plate for the children to turn into another mask. His tattoos took 20 hours (2 x 10 hours with a one hour break in between – mostly for the tattooist) using a needle and a chisel :shock:, with all his family around to support him. The tattoist was his cousin and you have to be a good wood carver before you can tattoo. You get them at puberty, each one is individual, and it represents having a baby (as men can’t have a physical one). Anthropology in the flesh!

On the bus back, J had conversation with Katy and me about money because I think the museum had reminded him of the culture that has shells threaded onto a necklace as currency. We started with bartering, and how the problems with it (trading a fraction of a cow for 4 apples is a bit tricky) led to the creation of money which is in itself useless.

While cooking tea J scrounged some uncooked pasta for everyone, and K turned his face pots (prosthetic ears) from the museum plus some of the pasta plus some sticky tape into a shaker. A strange game was invented while I cooked, involving some tongs from the kitchen, K’s shaker and the remote control for a toy – all of it was turned into a toaster with a slot for the bread (or something – I overheard bits, didn’t see any, but kept them amused for quite a while).

Just in case you thought the sun always shines in this blog(!), on Sunday morning J found some dark blue nail varnish from a box buried in a corner of their room waiting to be unpacked. He ended up with all blue finger and toe nails, K some of each, L a bit, plus lots on her hands :roll:. They were still rather blue at church, which was JMA Sunday where J and the other children his age or older collected certificates from the Minister for raising nearly Ă‚ÂŁ400. I don’t think he was phased by J’s blueness!

Flying solo

On Friday I had my first whole day as sole parent for a long time, as Katy was off to London to help sell nappies at a baby show.

After the common getting dressed inertia, I managed get everyone into the car and off to the post office to pick up undelivered parcels, then off to Friday Club. The children had all been before but I hadn’t, so the fear of not finding the place and so on was tempered by finding out what they get up to as I’ve heard about it a lot. It was in a village I’d never been to but fortunately it was easy to find.

There were only three other families – the planned nature walk plus bad weather plus half term may have scared people off. Shoes off at the door led to lots of skidding on the polished floor (this appeared to be normal). It is a churchy group, so prayers and songs first, and the we did a bit about autumn weather via percussion instruments which was nice. Each child had to pick an instrument and think how it could represent weather: L had triangle for gentle drops of rain, K had maracca for wind in the trees, J was heavy rain and we all did thunder by stamping on the floor. As the leader told a story everyone had to join in as the weather did their thing.

After that were slightly disorganised but fun games. I had the unenviable task of dividing a mixed age and ability group with several sets of friends into two roughly equal teams. Then was snack time where Katy’s cooking was enjoyed by all. Next was the main event – the nature walk. Down to the local recreation ground for a walk looking at trees (autumn leaf colours, conkers, seeds etc.). The rain had stopped, the sun was out and the children and adults enjoyed themselves. Back for lunch, then painting things we’d collected (L did some abstract art, K did a good set of conkers and J drew a huge mushroom he’d picked showing all the gills). More songs then home via some playing the churchyard. On the way home we got stuck in the [mostly private] school run. Another benefit of Home Ed. to society in general is that, even when we do drive to things, it’s rarely at rush hour if we can at all avoid it.

Tea and bed solo (Katy was still on her way back from London). I was at last re-united with my beautiful wife who was exhausted after standing pretty much all day :(. Being masochistic I decided to end the day trying to sort out our old scanner with our current PC, so that we could submit the children’s entries via email to the Nature Detectives competition at the last minute as the deadline appeared to have just passed. I went to bed late and defeated :(.

Out of the mouths of babes and infants…

This is mostly so we don’t forget them.

Katy was talking about knocking on doors and ringing doorbells and so on and said when the postman comes he’d just go “RRIIINNNNGG RRIIINNNNGG RRIIINNNNGG!”. K said “What, make the noise with his mouth?” (like Katy had just done) :). I can just imagine our postman standing on our doorstep with a parcel in his hand, not knocking on the door or pressing the doorbell, but saying “RRIIINNNNGG RRIIINNNNGG RRIIINNNNGG!” in a loud voice. Then moving along to next door and repeating it…

One Sunday recently we succumbed to the gorgeous smell of curry from the restaurant next door but one to our church and went there for lunch. The children were all a joy to be with – they tried all the food (although we limited ourselves to things we thought they’d like) and behaved very well and also seemed to be enjoying themselves and interested in the pictures on the walls. There was a lady sat near us having her lunch and as we left she commented on the children to Katy. As we were walking down the road afterwards, Katy said “The lady said to me ‘You have the most delightful children.'” (or something like that). K said “Don’t worry Daddy, I think she meant your children too!

This morning the boys had got dressed without any encouragement from me, which was nice. As they finished breakfast J said “I’m dressed!”. K said “Me too!” L said “I dressed too!” Being a boring parent, worried about the literal truth of things rather than seeing the Big Picture I said “No L, you’re completely naked.” She said “I wearing my plaster!” – which is true, she has a lovely pink plaster on that she got yesterday, so she wasn’t completely naked.

In case you’re wondering, the title comes from the Bible, either Psalm 8 or, when Jesus quotes the Psalm, from Matthew chapter 21, verse 16, except you’d need to pick a different translation to get those exact words – NIV uses “babes and children” and the King James uses “babes and sucklings” 🙂
