Wonder how long it takes for C++ devs to adopt std::optional over surrogates (-1, 0, npos, etc.) or pointers. 🤔

My talk "When to give up, and how?" from NDC{TechTown} is out on YouTube.

There were numerous problems with the microphone, so the viewing experience is maybe not great.

B/W photo of a lynx facing right. It's sniffing a pole. Huge paws, tufty ears and a short tail that it dark on the end.

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.
This is the saddest day of my professional life. Today is not only the final recording of the latest series of The Infinite Monkey Cage, it is my last ever Monkey Cage. I never thought that I would have to leave the show. I always imagined going on until | dropped dead under the studio lights due to a brain aneurysm caused by my final attempt to understand notions of quantum gravity or the shock of being told about fly maggot infestations in the sacks of macaque monkeys. I resigned in September, after sixteen years of dedication to the show, A show that I named and helped develop over all those years. Unfortunately, my opinions outside the BBC have been considered problematic for sometime, whether it has been voicing support for the trans community, criticism of Donald Trump, numerous other outlandish opinions, including once gently criticising Stephen Fry. These things were considered to conflict with being a freelance BBC science presenter In a recent meeting where BBC Studio executives again voiced problems with me, I realised my choices. Obedience and being quieter to remain making Monkey Cage, or 'Resign and have the freedom to speak out against what I believe are injustices'. • I chose the latter. It broke my heart. I love this show and I love the audience, and it is because of the audience in particular, that this decision was so difficult to make. I kept thinking about all the extremist voices promoting hate and division. They are being given so many platforms, while voices that represent kindness, open mindedness, empathy seem to be scarcer and scarcer. I felt I couldn't pamper myself with the luxury of silence. One of my many privileges is that I am able to resign and I can speak out even if it is to the detriment of my career. I have thought a lot about my heroes, Sinead O Connor, James Baldwin, Audre Lorde, and so many more. I think of Sinead's words, "the job of an artist is to be themselves at any cost". James Baldwin said prejudice was really just a word for cowardice. Audre Lorde, viewing her life, wrote that her only regrets were her silences. I think of my father as I resign, he brought me up to believe in fairness , justice and kindness. Though my heart is broken, it is also full of fire. I apologise to our incredible listeners for my departure, your love of the show means a great deal. I am so sorry to let you down. I hope that you can understand my reasoning. I have to accept that I am not what the current BBC expects of their freelance presenters. Despite this I should add that I have always worked far more than my contracted hours to try and ensure the show was always the best it could be, as well as making myself accessible and responsive to the audience wherever and whenever I met them. Every night, we have recorded, I have been filled with determination to make the best show possible. This was not "just a job" I hope that with my departure I can be a better ally to the LGBTQ community, to the neurodivergent community, to activists fighting against those who aim to brutalise society, to those currently in prison on hunger strike, and to all those who fight for a more inclusive world. From many conversations, I know there are many Monkey Cage listeners who support these communities and activists too. The strawberry is dead. Long live the strawberry. B

The Norwegian Institute for Nature Research set up a wildlife camera near our summer house in the Arctic a couple of years ago. We just realised that it has captured images of lynxes! These are my favourite animals, it makes me so happy to know they are walking around on our land up there.

We lived in a pub when I was growing up and when I was 3 (50 years ago!) we had someone in to draw the pub for a business card. I sat next to him and watched him draw every line. I was transfixed and it was a huge inspiration for me. I’ve dreamt about owning that drawing for years…

We have zero plans to put AI in LibreOffice, of course. Our focus is privacy and letting you control your data. Some users want AI features and they can get them via optional extensions made by the community – but we won't put it in the app itself.

📣 Germany's close to reversing its opposition to mass surveillance & private message scanning, & backing the Chat Control bill. This could end private comms-& Signal-in the EU.

Time's short and they're counting on obscurity: please let German politicians know how horrifying their reversal would be.

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...
