Last week, I attended

 “AI” UK

– which was organised by

 The Alan Turing Institute

and where I served in a minor role on the program advisory committee – and a workshop on

 Responsible “AI”

, co-organised by some fellow fellows of the Software Sustainability Institute.

is an ongoing documentary photography project that we (that is Eugenia and I) are working on. The project covers how small villages &amp; hamlets across rural Argentina – in particular the Argentinean Pampa – are changing and adapting in response to transport shifting from rail to road.

The

 Wassail

or

 orchard-visiting wassail

is an English tradition in which people bless their fruit trees to ensure a good harvest come autumn. Typically, these celebrations and blessings are accompanied by song and dance – including Morris dancing – and bring the local community together.

Happening just a week after the

 London Pride

event/parade, the

 London Trans Pride

gathered more than 25,000 people for a march from Trafalgar Square to Wellington Arch at Hyde Park Corner – despite a rainy start. The more mainstream crowds attending the

 London Pride

have turned the event into a party-like spectacle. In contrast, the

 London Trans Pride

consciously sticks to being a political protest march.

In October 2022, Eugenia and I spent a few weeks in Laos both in Vientiane and Luang Prabang. A big reason for going was that Eugenia gave some workshops in Vientiane, but we also gave some school lectures through Lecturers Without Borders while there.

If you have spent any time on Mastodon and are intested in data visualisations, geography, RStats, or any of the intersections thereof, you are likely to have seen the stunningly beautiful 3D map visualisations that @terence has been creating with the rayshader package. I have been itching to get an excuse to play around more with this myself,   and finally found a lovely one within the context of another little project.

La Grande-Motte is a comparatively new commune in the Hérault département in Occitanie in southern France that was built in the 60s and 70s in what used to be a marsh. The city was planned by a single architect – Jean Balladur – who was inspired by the works of Oscar Niemeyer and pre-Columbian, Aztec pyramids.

Last week I attended the

 The European Festival of Journalism and Media Literacy

, to join a panel on

 Artificial intelligence – Which skills do I need?

. Moderated by Lee Hibbard, the panel consisted of writer Maria Farrell, computational linguist &amp;

Flickr

as one of the old school photo sharing communities celebrated it 20th birthday on February 10th, 2024. To celebrate, there were photo walks in many different places around the globe, including in London. Beyond lots of

 Flickr

themed swag, our photo walk also took us into the

 British Museum

. The

Flickr group has a thread where you can find links and images of a lot of the other attendees.

In April 2023, I went to Argentina with the main reason being attending the 7th CSVconf in Buenos Aires. But of course we also went to visit Eugenia’s family over Easter. And we also managed to squeeze in some Lecturers Without Borders while there, even one in German for myself! Between all of these things we also found some time off for sightseeing.

Having recently moved from Paris to London, it was time to get a new nametag for our dog Ohana – as the old one still displayed Eugenia’s old, French phone number. This wasn’t great as many folks don’t have phone contracts that allow calling abroad (thanks Brexit?).  Ohana’s old name tag was custom-made with a laser cutter – for both cutting the shape and adding her name and the phone number.

Socrates I’m a huge fan of the

 Quantified Self

and

 Personal Science

movement in which one uses empirical methods to answer personal questions. Related to that, I try to collect and mine as many personal data sources as possible. And visualizing the data to learn from this is the part I really enjoy.

Quantified Self

On the weekend of September 17/18, 2022 the annual European Heritage Days took place again. During this weekend many monuments which typically aren’t openly accessible open their doors for the general public. Amongst the buildings that are open to the public during these days is the

 Palais du Luxembourg

, which was built in the 17th century and has been housing parts of the French legislature since the 19th century.

With France being back in a second lockdown (though the rules are a bit less strict this time around), I thought it would be interesting to look at the impact of different habits a bit more.

The COVID-19 confinement in Paris and France at large lasted from March 17th to May 11th, with comparatively strict measures on when you could leave your house, where you could go and for how long &amp; when you could be outside. As a result a lot of folks, including me were forced to drastically change their daily routines, shifting to a home office approach.

The effects the COVID-19 lockdown had on me

at the first European

Quantified Self meet-up. I already showed some of my insights here on the blog, but I added some more data analyses for the presentation, including my movement patterns from the GPS data and details on phone usage.

US Senator Kamala Harris held the launch rally of her campaign for US Presidential election in Oakland on Sunday, January 27th in Downtown Oakland. A crowd of around 20,000 people showed up, filling the streets around city hall at Frank H. Ogawa Plaza. People (and animals) of all ages spent hours in line, waiting to gain entrance to the plaza itself, blocking off a whole city block in a snaking queue.

Santa Con: What started out as anti-capitalist performance art in San Francisco (hanging Santa included), has turned into a ‘reviled bar crawl’, across the US.  So also in San Francisco in 2018 where hordes of Santas took over Union Square on Saturday, 2018-12-08. And it wouldn’t be San Francisco if a group of naked Santa was missing.

On November 8, 2018 the Camp Fire in Butte County started and wasn’t contained until November 25, 2018. With at least 88 dead, 62,053 ha covered by the fire and over 18,000 destroyed structures it was the deadliest and most destructive wildfire in California so far. Over 52,000 people had to evacuate their homes. Soon, the smoke of the fires reached down to the Bay Area, leading to an increase in air pollution.

Participating in the

 Mozilla Global Sprint

is somewhat of an annual ritual for me. This year’s installment took place on May 10/11. As

“

 Algorithm

” is a word that has become more and more meaningless in our day and age – given how it is thrown around everywhere. If you bring it up with people who didn’t undergo some form of tech initiation – be that formal education or self-learning - it’s easy for them to conjure a picture like the one above: A colourful mess of things, too complex to understand if you don’t have some advanced degree in computer science.

President Bartlet of

 The West Wing

is calling his famous “What’s next” to his secretary after managing a task. I just defended my PhD last week, and one question from virtually every person who attended and stayed for the after-party:

 What’s Next?

Which initially felt a bit weird. After all, I already took my next step three months ago when I joined

 Open Humans

as the Director of Research.

Open Humans, what’s next?

The first month in Berkeley – and with that also with

After having had some time to reflect on my writing process I’d like to share some of the things that I found useful during the writing of my PhD thesis. There’s probably already a million of these articles out there, but this also means that one more shouldn’t make much of a difference, so here we go. In principle this should all be applicable for other thesis writings as well.

Today I finally submitted my PhD thesis (🎉) and what better way to celebrate that day than doing some data analysis and visualization, right? So, let’s get some idea on how much time the actual write-up took after all and how I spent my time during these weeks. Luckily, I’m running

 RescueTime

on my machines. The service allows you to monitor how, when and how long you’re using your computer.

Philipp and I again participated in the

In the process of doing research for a snarky tweet I was looking for the yearly subscription costs of

 Nature

. In itself not an easy task, as the corresponding page one finds via Google is devoid of content.

Last week the

 The Royal Society

issued a joint statement about the importance of the international nature of research along with national academies across the UK and Europe. At the same time they started the hashtag

, where individuals reported what nationalities are collaborating in their labs. I, and many others, reported their lab’s composition using the emoji flags.

This website has included a little

 personal API

in the footer for quite a while. But in recent-(ish) months I’ve expanded a bit on it, as you can see in the screenshot above. It now also makes an informed guess on whether I’m likely doing okay on a given day or whether I might be under the weather – for example because of falling sick, having slept poorly or other factors.

In August 2022 I went to visit Wetzlar and the Leitz-Park together with Vinh. Beyond checking out the old city, we were particular interested in going to the Leitz-Park as it is the birth place of Leica cameras and 35mm photography more broadly.

Paris came out on 2020-06-06 for local #blacklivesmatter protests today. A part of it took place in front of the US embassy at Place de la Concorde, with the police fencing off the area widely. Another group gathered at the Champs de Mars facing the Eiffel Tower.      The full image set can be found on Flickr.

Geotagging photos in

 Adobe Lightroom

. After semi-accidentally ending up at SantaCon in San Francisco last weekend, I was wondering how I could geo-tag my photos more easily. If you’re only taking pictures with your smartphone, that’s not much of an issue as the internal GPS applies the metadata automatically. But lots of modern cameras still don’t come with an internal GPS or require some ridiculous add-ons.

Mozfest is

 Mozilla

’s annual festival that brings together technologists, activists, scientists, artists and many more for a weekend in London’s Ravensbourne College. Unlike schedules of many other events, time for passive consumption of talks can barely be found. Instead, workshops make up the bulk of the schedule. And even the science fair &amp; demo parts consist largely of lively discussions between participants.

Being more of a dog-person (or to stay in

The dynamic footer of my website has been powered by a little aggregation of some of my personal data for about 5 1/2 years by now. Until recently, all the data related to my activity and physiology (steps, heart rate, sleep, body) came from an Oura Ring.
