It’s probably a boy!

Today we have been for the 20 week “anatomy scan”, once again Mrs SomeBeans was invited to fill her bladder before attending the clinic for an ultrasound scan (pictures to be found at the end of this post), a scheme whereby good timekeeping is important.

Strangely we found the images less easy to interpret than those in the dating scan, much more internal structure of the brain, the heart and so forth is visible but the overview is less clear. I don’t know whether it was simply the bedside manner of the sonographer but this scan seemed much more business-like than the last one.

This time I took care to check out the model number of the ultrasound scanner, it was a GE Voluson E8. Alongside the ordinary scans shown below, we also saw Doppler shift scans: an overlay in blue and red which shows the flow of blood through the heart.

Finally, the sonographer suggested that it’s probably a boy. I feel this places on me a great responsibility to act as a role-model!

Photographing Chester

I’ve lived in Chester for 7 years but realised recently I have scarcely any photos of the city, so a few weeks ago I went off on a morning of indiscriminate photography using a Canon EF-S 10-22mm f3.5-4.5 on my Canon 400D. You can see the results of my labours on this and an earlier trip here.

The 10-22mm lens is a nice, very wide-angle lens but as you can see below it can produce some odd effects when used close-up to take picture of buildings. This can be seen in the picture of Chester Library shown below:

Chester Library

The library is housed in the old Westminster Coach and Motor Car Works, built around 1913-14 with a rather nice brick and terracotta front (see history here).

Aside from my usual problem of apparently having one leg shorter than the other, the verticals in the building converge. The “short-leg” problem can be fixed using Picasa, the aesthetic problem of converging verticals needs a different approach.

It’s worth pointing out that the image shown above is “correct” in the sense that the vertical lines of the building should converge because the top of the building is further away from the photographer than the bottom of the building. This problem is more severe when using a wide-angle lens. I want something that looks like the image below; what’s sometimes known as an “architectural projection”.

TheatreRoyalBirminghamWyatt1780

In the old days an architectural projection could be achieved using tilt-shift lenses or rather odd darkroom techniques. By the way, Cambridge in Colour, linked to for tilt-shift above is my first port of call for the mechanics of all manner of photographic things.

These days perspective corrections of this sort can be achieved using software, such as Hugin. Hugin is designed as a photostitching software but as a side-effect of this it needs to have all manner “projective geometry” knowledge. Projective geometry relates the real, 3D world to what will appear in a camera (a 2D projection of that world); it’s important in machine vision applications, computer graphics and in this sort of image processing.

The process of “correcting” converging verticals is described in a very good tutorial on the Hugin website. There is also a related perspective correction tutorial, this stops both horizontal and vertical lines from converging, this can have the effect of shifting you from an oblique view to a square on view (sort of). Applying this to my original image of the library we get this:

Chester Library

Which I find rather pleasing. This is Chester Town Hall, built in 1869, similarly treated:

Chester City Hall

Finally, the Blue Coat “Hospital” which was never a hospital but actually a school, it’s also a demonstration of the perspective correction pushed a little too far, something odd is going on with the dome tower. This is because the things I am applying a warp to are not all in the same plane.

Blue Coat Hospital

It’s easy to grow familiar with a place, not realising it is a little bit special. Chester really is architecturally special although it’s at times like this I wish there was a filter for modern signage and vehicles. There are a number of black and white “timber framed” buildings, often these are “mock” dating back to the late 19th century:

Building on the Watergate/Bridge Street Corner Whilst others are genuinely old, such as the Bear and Billet Inn built in 1664:

Bear and Billet Inn

The Three Old Arches is reputedly the oldest shop front in England:

Three Old Arches dates 1274AD

And there are all manner of interesting little twiddly bits, I keep spotting more of these each time I visit now:

Friday rant

t-mobile get the pointy end of this because they come at the end of a day wherein I was assailed from all sides by idiocy.

18 months ago I became the proud father of Shiny, an HTC Desire phone on a contract for £20 per month, a novel experience for me. Shiny is mainly used as a internet access device rather than a speaky texty phone and I’ve been very happy with it.

So at the end of 18 months I am free of my original contract to t-mobile and can seek something cheaper, the key thing being unlimited* internet access. I look on the t-mobile website: it says they’ll offer me £6 off my contract going forward for a 12 month lock-in or some such. Carphonewarehouse, on the other hand, offers me a £10 per month SIM Only contract with t-mobile on monthly rolling basis, oddly 12 month contracts are £15. This, anyway, is a “no-brainer”, I get a monthly rolling SIM only contract with t-mobile contract for £10 which is less than the t-mobile renewal offer of £14. This requires a conversation with carphonewarehouse’s call centre which sounds a little cramped because I can hear my man Paul’s neighbour demanding a stapler and another having somewhat groundhog-day sounding conversation about “which shop did you get this better offer in?”

Anyway this is sorted, all I need to do is ring up t-mobile once my new SIM card is delivered and get my number transferred from my old account to my new one. Apparently this requires t-mobile to provide my PAC number to themselves (don’t ask me!).

Fail one is that on ringing the t-mobile 150 service I get a list of numeric options: I need option 2 but the service doesn’t recognise my many and creative ways of pressing the 2 key on my keypad. Actually it’s a softkey rather than an actual real key but it had 2 written on it so I pressed it.

By pressing 1 I get through to an actual person who establishes that I need transferring to their cancellation department – you see I currently have two contracts with t-mobile and I want to cancel the old one and transfer the number to the new one, as an interesting aside the chap at carphonewarehouse told me my credit rating is so good I can have 4 contracts! The person I’m talking to has a pleasant Irish accent although I can’t help thinking she is actually an Indian who has been trained to speak with an Irish accent to reassure me#.

After waiting on hold for a few minutes I get another person this time with a pleasant Welsh accent (proviso as above), anyway she tells me I “can’t” transfer my phone number from one t-mobile account to another. Now I’m a bit hardline on these things: I can transfer a number from a non-t-mobile account to a t-mobile account by invocation of the PAC number therefore logically I “can” do the described transfer therefore “can’t” actually means “won’t”. However, it turns out that I can convert my existing contract to a £5 per month contract equivalent to my new SIM only contract but with a 24 month contract period. Needless to say this was not visible on any website. We agree to do this.

So at the end of two rather complex phone calls I have reduced my phone bill from £20 per month to £5 per month (actually £6 with VAT). I do have a PhD, and whilst this may not endow me with great nouse, it does mean I’m not a dribbling idiot – yet to me this process has been ridiculously Byzantine and complex. It’s taken me two 20 minute phone calls to do what should be a couple of button presses.

I do feel sorry for the poor souls that inhabit these call centres because I’m actually a polite sort of chap but the wrangling I have to engage in does make even me a bit tetchy and they, through no fault of their own, get the pointy end of that.

Addendum

Wednesday and I’ve just had a chat with t-mobile again, because my online account info doesn’t match what I agreed on the phone on Friday, currently it indicates that my contract is for £8.51 per month exc VAT and that I don’t have the farcically named “unlimited” internet access I signed up for. They assure me that when I get my next bill it will be for £5 plus VAT and the required “unlimited”.

The problem here is that they’ve sent me several messages telling me how great their online account info system is, meaning I’ve gone off and looked at it. What they’re actually trying to do is hide how little they’re willing to charge me for a mobile phone contract. This is all explained nicely in Tim Harford’s book “The Undercover Economist“, the trick is to find out the maximum someone is willing to pay for a service and offer it to them, without prejudicing your efforts with other customers who have a higher maximum price. Price transparency would spoil this game.

Footnotes

*for values of internet access which are limited; actually how do they get away with describing limited internet access as “”unlimited”?

#Personally I don’t care that the call centre might be in India but I am offended that they feel the need to fake an accent to “reassure” me. It’s quite possible that t-mobile’s call centres are actually in England and I have maligned an Irish lady and a Welsh lady.

The Sandstone Trail

SandstoneTrailCropped

The Sandstone Trail walks (click to go to Google Maps)

These days we frequently hear stories of heroic acts of walking: to the Poles, across the Andes, up the Amazon, often undertaken at great speed or under conditions of considerable disability.

This little post is a record of our trek down the Sandstone Trail, 34 miles close to our home in Chester. Our route, drawn from “Circular walks along the Sandstone Trail” by Carl Rogers, adds up to a total of 77 miles. These distances are the sort of things that serious trekkers would cover in less than 24 hours, probably combined with a swim and a 100 miles cycle. Our effort was rather more leisurely – it took us about 14 months. Traditionally we walk on a Sunday morning, usually finishing before lunch.

The Sandstone Trail is covered in 13 walks:

  1. Frodsham
  2. Manley Common
  3. Delamere Forest
  4. Primrosehill Wood
  5. Tarporley
  6. Beeston Castle
  7. Peckforton
  8. Burwardsley
  9. Rawhead
  10. Hampton Heath
  11. Malpas
  12. Tushingham
  13. Whitchurch

These range in length from 5 to 8 miles.  To start off, here is some of the eponymous sandstone, in this case from above Frodsham:

The sandstone is from the Sherwood Sandstone Group laid down in the Early Triassic, 250 million years ago.

The small town of Frodsham lies close to the Mersey Estuary and after you have climbed up onto the sandstone heights above the town you get a fine view towards Liverpool and across the industrial works at Stanlow refinery and Runcorn. I’m rather fond of these, Runcorn is a fine collection of pipes, tubes and the odd ball shaped thing whilst the Stanlow refinery looks like something out of Bladerunner; at night they are lit up with gas flaring off on some of the chimneys.

The walks to Primrosehill Wood are rather pleasant, at Manley Common we were inspected by enthusiastic pigs.

Pigs!

We also saw a lot of cows:

And a llama (rather further along the Trail):

The llama was very inquisitive, perhaps overly so since there was a small diversion around its field with a note highlighting that dogs and walkers with sticks had interacted with it rather more than was strictly desirable. As we walked past its field it followed us very closely over the fence with a look of what could have been either llamaly inquisitiveness or aggression.

For me the Tarporley and Beeston Castle walks were a bit of a slog, they span the Cheshire Gap, a flat area of clay farmland. The Beeston Castle walk in particular comprises a trip out into the plain and then back again with the Castle the sole point of interest for the whole walk. The Castle is pretty impressive but you have to pay to get in, so we didn’t.

The next three walks, Peckforton, Burwardsley and Rawhead are my favourites, at this point the Sandstone Trail heads up onto a wooded ridge with lovely views in all directions. The Peckforton Estate has left some classy stonework along the route.

The last four walks: Hampton Heath, Malpas, Tushingham and Whitchurch take you off the  ridge for more walking across rolling farmland with a couple of stretches along the canal. We did manage to get very wet one day:

Me, wet

This was achieved by crossing a field of oil seed rape not long after heavy rain, I think this is the wettest I’ve ever been following a walk (and I’ve walked in the Lake District!). As you can see the crop reached a height of approximately five feet and held an awful lot of water.

I must admit to not being too fond of this type of walking but we could not leave walks undone. This little arch, in Jubilee Park in Whitchurch, marks the end of the Sandstone Trail.
