Turning the Thames into a swimming pool is a nice way to reclaim a city's dead public space

There's a lot of water in the Thames, so wouldn't it be nice to give people access to it for a bit of fun?

The urban design trend in the major cities of the world is for the reclamation of disused infrastructure, for conversion into something more civic-minded. The progenitor is the High Line, New York City's newest park, lovingly-cultivated along the length of a disused elevated freight line along the western edge of Manhattan. It's very nice - not revolutionary, but certainly revelatory.

For planners in London looking to do the same thing, the best option would probably have been the Kingsland Viaduct if it hadn't been repurposed for the London Overground's extended Dalston-to-New Cross East London Line in 2010 (and a damn good thing too, how it's already in need of capacity improvements to cope with passenger demand). No, Londoners will have to make do with the much-fêted Thomas Heatherwick-designed pedestrian Garden Bridge, which, if it gets planning permission and funding, will cross the Thames from Temple to the South Bank. Maybe, though, that's skipping over and ignoring and under-used resource that's been in front of planners the entire time - the Thames.

Late last year, the Architecture Foundation put out a call for entries to a series called "London As It Could Be Now", searching for "new ideas and visions for self-selected sites along the Tidal Thames reflecting on relevant changing social, economic, cultural and environmental conditions and concerns". That means things like bridges, airports, houses - the usual. But one of the entries, which was revealed in November but which I've only just come across, is Thames Baths, by Studio Octopi. It's a cute public pool constructed on the Thames, at the site of where Blackfriars Pier (one of TfL's water taxi stops) is:

The studio writes:

Swimming has always featured in the River Thames. The ability to do so has become harder and harder as river traffic has increased and London’s population has outgrown the ageing sewage system. However plans are in place to upgrade Sir Joseph Bazelgette’s sewers and therefore dramatically improve the quality of the river’s water. The Thames Baths Project is about imagining the possibilities of safely swimming in the river and opening up a discussion about the future."

It's interesting that they mention sewers, as the River Fleet - once effectively an open sewer, now an enclosed sewer - empties out into the Thames beneath Blackfriars Bridge, mere yards away from the pier. That's not something you want to have to find yourself swimming in when the tide switches direction and brings it back upstream. 

Still, it's a nice idea, and the kind of thing that would allow London to express itself architecturally without nicking good ideas from New York City. Semi-wild swimming is a very London thing - see: Hampstead Heath ponds, clubs taking dips in the Serpentine, the use of Shadwell Basin as an outdoor watersports centre - and it would be fantastic if it was a genuinely public space, as the trend in the capital is for the privatisation of new public amenities like squares or parks.

It can also be seen as a less-ambitious version of the LidoLine, a 2012 proposal by Y/N Studio to convert the mostly-disused Regent's Canal, which runs from Islington to the Thames via east London:

It was pitched as an alternative route for commuters, but since the canal kind of skirts around the edges of central London (where people tend to work) it might be better-suited for leisure time. However, the difficulty of keeping rat faeces and shopping trolleys out of the water - seriously, it's big problem in the canal for anyone who happens to try swimming in it at the moment - make it unlikely. Alas.

This Ada Lovelace Day, let’s celebrate women in tech while confronting its sexist culture

In an industry where men hold most of the jobs and write most of the code, celebrating women's contributions on one day a year isn't enough. 

Ada Lovelace wrote the world’s first computer program. In the 1840s Charles Babbage, now known as the “father of the computer”, designed (though never built) the “Analytical Engine”, a machine which could accurately and reproducibly calculate the answers to maths problems. While translating an article by an Italian mathematician about the machine, Lovelace included a written algorithm for which would allow the engine to calculate a sequence of Bernoulli numbers.

Around 170 years later, Whitney Wolfe, one of the founders of dating app Tinder, was allegedly forced to resign from the company. According to a lawsuit she later filed against the app and its parent company, she had her co-founder title removed because, the male founders argued, it would look “slutty”, and because “Facebook and Snapchat don’t have girl founders. It just makes it look like Tinder was some accident". (They settled out of court.)

Today, 13 October, is Ada Lovelace day – an international celebration of inspirational women in science, technology, engineering and mathematics (STEM). It’s lucky we have this day of remembrance, because, as Wolfe’s story demonstrates, we also spend a lot of time forgetting and sidelining women in tech. In the wash of pale male founders of the tech giants that rule the industry,we don't often think about the women that shaped its foundations: Judith Estrin, one of the designers of TCP/IP, for example, or Radia Perlman, inventor of the spanning-tree protocol. Both inventions sound complicated, and they are – they’re some of the vital building blocks that allow the internet to function. 

And yet David Streitfield, a Pulitzer-prize winning journalist, someow felt it accurate to write in 2012: “Men invented the internet. And not just any men. Men with pocket protectors. Men who idolised Mr Spock and cried when Steve Jobs died.”

Perhaps we forget about tech's founding women because the needle has swung so far into the other direction. A huge proportion – perhaps even 90 per cent - of the world’s code is written by men. At Google, women fill 17 per cent of technical roles. At Facebook, 15 per cent. Over 90 per cent of the code respositories on Github, an online service used throughout the industry, are owned by men. Yet it's also hard to believe that this erasure of women's role in tech is completely accidental. As Elissa Shevinsky writes in the introduction to a collection of essays on gender in tech, Lean Out: “This myth of the nerdy male founder has been perpetuated by men who found this story favourable."

Does it matter? It’s hard to believe that it doesn’t. Our society is increasingly defined and delineated by code and the things it builds. Small slip-ups, like the lack of a period tracker on the original Apple Watch, or fitness trackers too big for some women’s wrists, gesture to the fact that these technologies are built by male-dominated teams, for a male audience.

In Lean Out, one essay written by a Twitter-based “start-up dinosaur” (don’t ask) explains how dangerous it is to allow one small segment of society to built the future for the rest of us:

If you let someone else build tomorrow, tomorrow will belong to someone else. They will build a better tomorrow for everyone like them… For tomorrow to be for everyone, everyone needs to be the one [sic] that build it.

So where did all the women go? How did we get from a rash of female inventors to a situation where the major female presence at an Apple iPhone launch is a model’s face projected onto a screen and photoshopped into a smile by a male demonstrator?

The toxic culture of many tech workplaces could be a cause or an effect of the lack of women in the industry, but it certainly can’t make make it easy to stay. Behaviours range from the ignorant - Martha Lane-Fox, founder of, often asked “what happens if you get pregnant?” at investors' meetings - to the much more sinister. An essay in Lean Out by Katy Levinson details her experiences of sexual harassment while working in tech: 

I have had interviewers attempt to solicit sexual favors from me mid-interview and discuss in significant detail precisely what they would like to do. All of these things have happened either in Silicon Valley working in tech, in an educational institution to get me there, or in a technical internship.

Others featured in the book joined in with the low-level sexism and racism  of their male colleagues in order to "fit in" and deflect negative attention. Erica Joy writes that while working in IT at the University of Alaska as the only woman (and only black person) on her team, she laughed at colleagues' "terribly racist and sexist jokes" and "co-opted their negative attitudes”. 

The casual culture and allegedly meritocratic hierarchies of tech companies may actually be encouraging this discriminatory atmosphere. HR and the strict reporting procedures of large corporates at least give those suffering from discrimination a place to go. A casual office environment can discourage reporting or calling out prejudiced humour or remarks. Brook Shelley, a woman who transitioned while working in tech, notes: "No one wants to be the office mother". So instead, you join in and hope for the best. 

And, of course, there's no reason why people working in tech would have fewer issues with discrimination than those in other industries. A childhood spent as a "nerd" can also spawn its own brand of misogyny - Katherine Cross writes in Lean Out that “to many of these men [working in these fields] is all too easy to subconciously confound women who say ‘this is sexist’ with the young girls who said… ‘You’re gross and a creep and I’ll never date you'". During GamerGate, Anita Sarkeesian was often called a "prom queen" by trolls. 

When I spoke to Alexa Clay, entrepreneur and co-author of the Misfit Economy, she confirmed that there's a strange, low-lurking sexism in the start-up economy: “They have all very open and free, but underneath it there's still something really patriarchal.” Start-ups, after all, are a culture which celebrates risk-taking, something which women are societally discouraged from doing. As Clay says, 

“Men are allowed to fail in tech. You have these young guys who these old guys adopt and mentor. If his app doesn’t work, the mentor just shrugs it off. I would not be able ot get away with that, and I think women and minorities aren't allowed to take the same amount of risks, particularly in these communities. If you fail, no one's saying that's fine.

The conclusion of Lean Out, and of women in tech I have spoken to, isn’t that more women, over time, will enter these industries and seamlessly integrate – it’s that tech culture needs to change, or its lack of diversity will become even more severe. Shevinsky writes:

The reason why we don't have more women in tech is not because of a lack of STEM education. It's because too many high profile and influential individuals and subcultures within the tech industry have ignored or outright mistreated women applicants and employees. To be succinct—the problem isn't women, it's tech culture.

Software engineer Kate Heddleston has a wonderful and chilling metaphor about the way we treat women in STEM. Women are, she writes, the “canary in the coal mine”. If one dies, surely you should take that as a sign that the mine is uninhabitable – that there’s something toxic in the air. “Instead, the industry is looking at the canary, wondering why it can’t breathe, saying ‘Lean in, canary, lean in!’. When one canary dies they get a new one because getting more canaries is how you fix the lack of canaries, right? Except the problem is that there isn't enough oxygen in the coal mine, not that there are too few canaries.” We need more women in STEM, and, I’d argue, in tech in particular, but we need to make sure the air is breatheable first.
