Discovering Swansea's Industrial Heritage #2

The boat trip up the River Tawe was very interesting but to get more intimate with a ruin, you have to go to the Aberdulais Tin Works and Waterfall. It's a National Trust site located in the Vale of Neath. My mother went there years ago when all that was apparent was the waterfall.

But there has been a lot of restoration and conservation work since, and it has revealed the ruins of the most recent industry to occupy the gorge - the tin-plating works. The site has housed a succession of mills since 1584 : copper smelting, iron-working, textiles and grain mills and, in the nineteenth century, tinplate.

Behind me is the old school, now the café
In its heyday, tinplate from the works was exported all over the world, and only stopped when the Americans slapped huge tariffs on tinplate imports to protect its own infant industry. Some of the Welsh workers went to the US to use their skills in the factories there.

The museum really tries to convey the conditions of the workers. There are videos, a small cinema, displays and objects dug up from the site. Local children tell the stories of their forbears on film, how they were put to work at the age of eight, and the terrible conditions they endured. It was so hot, for example, that sweat ran out of their shoes.

The wheel, that uses 400 year old technology, was built by students and apprentices of British Steel at Port Talbot. It's the largest electricity-generating wheel in Europe. It wasn't working when we were there, but it normally produces 100-120kw of electricity per day.

The turbine has a generating capacity of 200kw and provides electricity to most of the neighbourhood!

Small site, global impact!
Apparently the river is quite something when it's in spate. It was already quite dramatic during our visit after raining overnight.

It was an exceptionally interesting visit; well done the National Trust for all the work they've done to make the museum as fascinating as possible. 

They even provide picnic tables for those who bring their own food, which we did, and the rain held off while we ate it!

Discovering Swansea's Industrial Heritage #1

The fun part of holidaying with three generations is that you get to do lots of different types of activity. It's easier if the youngest is a teenager and not subject to the tyranny of naps, and that he is amenable to tagging along to things he might not be initially interested in.

Gower is full of history, and the Swansea area in particular, has an amazing industrial past. The Waterfront Museum at the Marina will have your eyes on stalks at the sheer quantity and variety of industry that has existed in Wales. Did you know, for example, that Swansea was known as 'Copperopolis'? It was the heart of the world copper industry in the nineteenth century.

Copper ore was mined in Cornwall and shipped to Swansea, a prime location because of its harbour and easy access to local sources of cheap, suitable coal. You need three to four tons of coal to smelt one ton of copper ore so it made sense to transport the ore by ship up the River Tawe to the copper smelting works in the Swansea valley. The copper was then transported to the factories in the Midlands.

If you take a boat ride from the Marina on the 'Copper Jack', you can see some of the remnants and ruins of this industrial powerhouse.

We floated slowly up the River Tawe along with a full boat-load of passengers ranging from pushchair young to wheelchair-bound old. Once out of the Marina, a DVD started on a screen at the front of the boat and described in real time what we were seeing and why.

We learned a lot about the industrial history of Swansea, and the damage done to the environment because of the success of the factories.

Chimneys and remnants of Hafod-Morfa copperworks
Separating copper from copper ore produced mountains of furnace ash and slag, and clouds of smoke laced with arsenic and sulphur. Workers were consumptive and the countryside all around was a desert. My mother was among the people on the boat who were locals and remembered what it was like, where absolutely nothing would grow.

They marveled at the transformation of the banks which are now a verdant green and abundantly covered with bushes and trees. The pollution ended only with the decline and extinction of the copper industry. Good for Nature, bad for business.

However, the Hafod-Morfa copperworks is being regenerated. It's on a twelve-and-a-half acre site that contains twelve significant industrial heritage buildings and structures. Wales has woken up to the importance of its history, and there is funding to make the most of what remains.

The Swansea project was started back in 2010 by the council in conjunction with Swansea University, lead by Professor Huw Bowen, and plans include the creation of a centre for tourism, business, education and work. They are creating interpretation trails and a living history laboratory where visitors can learn about Swansea's leading role in the Industrial Revolution and development of the global economy.

Swansea is the place to go with teenagers!

The end of the summer is approaching; my son is looking at school bags online as he left his on the TGV coming back from the UK (with ID card, carte jeune, crisps and a few clothes inside); I've been back at work for a week.

We went for two weeks to England and Wales, as usual, but did not do just usual things. For our trip to London, we visted the Bethal Green Museum of Childhood where I saw, to my joy, an owl just like my own "Sage".

Toy from Bethnal Green Museum of Childhood
Mine is a bit bigger than this one, and has a blue and green body in a material printed with feathers. He came from Heal's sale and the story goes that I was about 4 or 5 and could be seen staggering along with the owl almost as big as me, saying "Can I have this?". He had one wing a bit loose but that was quickly remedied with a sharp needle and cotton, and he's been in my room (chez parents) ever since. The museum is lovely, but the noise of screaming kids was phenomenal. Take ear plugs.

In Wales, we stayed in a lovely little bungalow in Bishopston near Mumbles. It also has a story. The owner, who lives next door, built it for his father-in-law about 7 years ago. He incorporated all the specifications required by the old man. Then, when it was all finished, and ready to roll, the father-in-law, an inveterate hoarder, couldn't face leaving his own home.

It had an amazing bathroom, with, most unusually for rented accommodation, a thousand pound's worth of free-standing bath on feet.

My youngest was the only one to get to try it because my mother decided she'd never be able to get out of it, and I preferred the shower. He found it was lovely to soak in after a good hour at Limitless, Swansea's trampoline park.

This is a fabulous place for kids and adolescents, or indeed students who want to play a game of dodgeball or organise a bouncy party. The noise levels were pretty high, so my mother and I retired to Starbucks about 100m away for a cup of tea while my youngest got on with bouncing off his energy.

While we were at that end of Swansea, we visited the new engineering faculty and management school of Swansea University. It's been built on reclaimed land from the docks, and is enviably close to the beach, called the ("pied dans l'eau") Bay Campus.

The town has two universities that are both expanding, and bringing much-needed investment into the area.

Another activity that we did, that was eminently suitable for teenagers, was FootGolf, along the Mumbles Road. By that time, my brother and family (two ado girls) had arrived, and this was one of the activities that we could all enjoy. My mother kept score, and I distinguished myself not one bit as an ace footie player. 

I remember the greens, sandwiched between the promenade and main road, as a 'pitch 'n' putt' where my brother loved to thrash me and got very annoyed when I didn't take it seriously, which of course made me all the keener to be silly. The new owners have enlarged the holes and bought a bunch of footballs, and created a very entertaining activity that even I enjoyed without being too much of an idiot. I had to cheat on the odd occasion of course, but I enjoyed trying to kick the ball more than hitting it with a stick. No one will be wanting to sign me up for their team any time soon though...

My youngest wanted another go at shooting innocent targets, so we went back to Perriswood where he shot the hell out of a range of metallic creatures and printed baddies.

Mother and I, on the other hand, were enjoying meeting Alice the lazy Eagle Owl, and Dave the dim Peregrine falcon as Perriswood is, primarily, a falconry centre where they do displays and rear rapaces. It also has lovely views over Oxwich Bay.

So a good time was had by all, and we even had good weather! Next up, hopefully, our visit to the Tin Works Museum at Aberdulais, and cruise on Copper Jack up the River Tawe.

A weekend in Lyon with motorbike ride into the Monts d'Or

While the UK has been agog with Brexit, the French with the footie and Tour de France, I (who couldn't vote) have been battling with my new project of learning C sharp, in the heat, with a rubbish internet connection and laptop that keeps overheating.


By way of distraction last weekend, I went to help my DB move from one well-appointed flat that he wasn't paying for (director's perks during his trial period) to one that he will be paying for (his trial period being at an end). (And while I was at it, take advantage of his super fast internet connection.)

The last time I was in Lyon it was also to help him move, funnily enough. This was a fairly painless affair because he was moving from one furnished flat to another furnished flat within the same city, so it just took a couple of car loads, a reasonable amount of humping up stairs, and a limited amount of cleaning (for me at any rate).

He moved from a flat with no view, to this:
Overlooking the Confluence district
The trees form part of a park that residents can enjoy, that goes right down to the river Saône, only separated from it by a main road.

Looking towards the centre of Lyon
The Alps are almost visible in the far distance.

The building is a former convent school
The flat, and building are full of original features, but it's all been nicely renovated too. Quite the des res!

On Sunday morning, we took a break and went for a motorbike ride into the Monts d'Or and Beaujolais. The local stone is a remarkable vibrant orange/yellow and makes for some charming villages.

The scenery was typically rolling hills, pasture, meadows, fields of cattle, scattered villages, leafy woods and, of course, vineyards.

This church positively glows in the sun
We were on the new bike (BMW1200 GS) which purred through the villages, and roared through the countryside. My DB loves the engine... The passenger seat is comfy too.

The pink ribbon was to celebrate some sort of Rosé day, I think
Beaujolais country
Either the fields in the photo above are on a slant or the village is. I can't quite make up my mind. As I took it from the back of a moving bike it could be either! The vineyards are part of the Beaujolais appellation. Let's hope they have a good year this year and produce lots of delicious wine.

Rolling hills, charming villages in les Monts d'Or
One village that we went through obviously had some eccentric inhabitants with a fine line in graffiti.
This is the best graffiti I've seen in France
We didn't stop to find out any more about who had created the artwork but I know that s/he is not impressed with the modern state of France...
Most graffiti around Montpellier is of the basic tagging type
My favourite said: "Julien Coupat - Eric Hazan (radical lefties) -> un livre d'opinion mène en prison au nom du terrorisme!".
Nifty artwork and wonderfully radical messages, plus a lovely red door

Love the skull on the left

Someone's been very busy!
We finished the day, later, with an apero outside a bar in the Croix Rousse quartier which is where all the bobos live. The air was balmy, the rosé iced, and it was lovely and peaceful, with just the murmur of conversation from tables nearby.

I could get used to that.

A day out at the Touratech Travel Event

Touratech is a German company that makes accessories for motorbikes. We're not talking seat covers with little hearts on or 'go faster' stripes here, but everything you need 'for your next adventure': vehicle equipment, riding gear, travel equipment, navigation and clothes. Their catalogue is the ultimate biker porn.

Bike with kit and Touratech teddy
They have a shop in Orange, and every year, organise the Touratech Travel Event at the Parc des Expositions. The programme is a varied mix of talks, rides out, workshops, skill testing, etc. We go, naturally, as Orange is just an hour up the autoroute, and it's a good day out. Not just for the stands that sell adventure packages in far-flung spots across the globe for thousands of euros each, or the vehicles of all sorts on display, but for the presentations by bikers who have actually been and come back from an expedition.

We thought about buying this for fun... (€32K)
If you think this sounds like a bunch of hairy bikers showing a few holiday snaps of big bikes and pints of beer, it isn't. Yesterday we listened to two women talking about what they had done, where they had been, and what they had seen.

One was a young woman called Stéphanie Bouisson whose team participated in this year's BMW GS Trophy
"Adventure, foreign cultures, new friendships, gravel, sand and dust make BMW Motorrad's International GS
Trophy an Enduro challenge that is second to none. International teams compete in intensive daily stages as
well as numerous special challenges. This also applied to the International GS Trophy 2016, which took place
in spring in the impressive landscape of Southeast Asia."

Look at this beaut!
Another speaker was Marie-Hélène Cambon, who, with her husband Jo, rode from Bordeaux to Iran on their motorbikes, stayed a month in Iran, and rode all the way back again! Their video of the trip was just stunning. Iran has some fantastic scenery, beautiful monuments, and welcoming people. A blog describing their trip with some of their photos can be seen on their website here.

Is is a bike, is it a car? No, it's a 3-wheeler d'enfer!
One of the themes we heard in all the talks was the desire by the biker adventurers to meet people along the way. Not just fellow bikers, but the local population, and they all talked about some of the amazing people they came across. A far cry from insular biker gangs who are just interested in themselves and duffing up others.

My toes touch the ground - must be my size... !
We listened to a talk by a guy who had shipped his bike over to South America and ridden from Valparaiso to Ushuaia and back. Again, amazing stories of the people he met, places he stayed, and the most incredible scenery.

Most of the bikers who gave talks were sponsored, or helped in some way by Touratech and other groups. In return, they agreed to talk about their trip at events such as the one this weekend.

The cutest car
The penultimate talk, however, was by Philippe Perrenoud, the guy who set up a Trail-Rando with his wife. He goes out and discovers trails and routes for Enduro adventures, then sets up an itinerary, makes all the arrangements and sells the result. He told us about he goes about discovering the trails which is a long and pain-staking business going down every single likely path.

He has set up trails all over the world, including in France, with, for example, a diagonal route from Deauville to La Ciotat. These trips have to be accompanied by a guide because the trails go through farms, need permission from everyone along the way (some 200 paysans) and can thus only take place a certain number of times per year. You meet the farmers along the route, and are welcomed rather than cursed. Baggage is carried on ahead, and all you have to do is enjoy the route.

We came away with our heads spinning with all the views, the stories, and enthusiasm for adventure.

Video Presentation of my Python Project

I had to present my Python project to the other students in the MOOC, and I did this using a very nifty software called Screencast-o-matic which lets you film yourself using the webcam and also records your screen and mouse action at the same time. For free, too, in the basic version which was perfect for what I had to do.

See me in action on my video explaining what I did, here:

My Python Capstone Project

I've done it! I've made it all the way through the Python for Everybody MOOC by the University of Michigan with the très sympa Dr Chuck (Dr Charles Severance) at the helm who took us through the highways and byways of Python and supported us with substantially complicated scaffolding. Much needed, in my case.

The last module in the 5-part course was the Capstone where we had the opportunity to do an optional project. Always game to get the most out of things, I decided to take the bull by the horns and sign up.

For the project, we had to find a data set, 'scrape' it to find some specific information, put that into a database, and finally, visualise the results. There are data sets about many different fascinating subjects such as:

  • the last words of inmates in Texas before execution since 1984
  • the "Million Base" of 2.2 million chess matches
  • a Twitter data set
  • World Health Organisation data set
  • Family food data set
  • Million Song data set

and so on. For my project however, I chose the Transport for London data set available in their Application Programming Interface (API). It provides access to real time data on the most highly requested information across all modes of transport. It also provides data on accidents across London. I wanted to find out about bicycle accidents (just because), and discover where most accidents happen. I thought it would probably be the City of London which is densely populated during the day and has high cycling activity (couriers etc.).

The first thing I had to do, I discovered, was apply for an API key giving me permission to scrape the data. Then I had to write the code, which I based on code we had seen during the course (click on the images to see them bigger and better).

This code creates the database, connects to the TfL API, asks for the year to download and inserts the longitude, latitude, severity and victim (cycle, car, motorcycle, etc.) into the database for that year. Then it saves the data and closes the connection.

It took me a few days because I wasn't sure about exactly what I needed to do - did I need to create a dictionary, or two, or none...? That's half the problem actually, for me - identifying the structure of the code you need to write for the job you want to do.

My code is really simple too. It just asks for one year, not multiple years. It assumes there are no errors in the year entered (e.g. 2016 which is not available yet). I could make it more robust, but to start with, I just wanted to make it work!

This is what the data looks like in the API:

TfL API raw data

This is what it looks like 'pretty printed':
TfL API data in readable format
You can see more clearly the information I wanted to download in the 'pretty printed' format.

This is what the database my code created looks like, it has 23116 rows of data:

I was astounded the first time the code worked and saw the database loaded with data. Someone I spoke to recently called the feeling a 'nerdy moment'. Never thought I'd ever have one of those, I must say!

Having got the data, I then had to write some code to select the cyclist accident set, choosing 'severe' accidents rather than fatal ones (too sad), iterating through the data, and writing the longitude and latitude locations only to a javascript file.

Code to select geolocation data
I was thankful to have some scaffolding to help me write that too!

The geolocations of severe cycle accidents in London

Once I had the geolocation data, I then had to visualise it. I had already used some visualisation code earlier in the MOOC, so just had adapt it to visualise my data. It actually took me three days because I ran into a problem and had no idea what to do. The code was written in html, which I know nothing about. I hunted around for a solution on the internet, including that fabulous resource Stackoverflow, but couldn't find an answer.

I was stumped. Then I moaned to my DB about my problem, and he said that I should check the latitude and longitude coordinates because they might not be in the right format. And he was right! They were back-to-front in my code! Once I'd fixed that, up popped the little red labels as they should (with another nerdy moment).
Great London severe accident sites
These maps show the severe accidents for 2008. There were 429, and you can see from the second map that the highest concentration was indeed the City of London.

Central London severe accident sites
Job done!

It's been a really satisfying few months, going from being a complete Python beginner/never having touched coding before, ever, and having been crap at maths, to producing an amazing, functioning final result that I had to understand to make work (more-or-less, let's just ignore the html...). Dr Chuck was an entertaining teacher who could engage with us across a screen (no mean feat), and who even set up live 'office hours' during the Capstone so we could interact with him directly. He was aided and abetted by a team of kindly mentors who were available to help us out and give advice in the forums.

I am very happy with the results, and aim to go on and tackle C# next!
