I guess I’ll cover the context first so that we can move on to the good stuff.
Man, everything is going terribly. It’s hard to overstate how bad things are for America right now. We’re just doing the thing: we’ve elected fascists and they’re funding an unaccountable military that will do their bidding. They’re doing the worst possible economic policy and attacking elected officials. The New York Times is actively fighting against New York’s Democratic candidate for mayor by publishing weak hit pieces day after day, and doing their weak-ass quasi-endorsement of Cuomo even after they publicly stated they wouldn’t endorse in local campaigns. Shame on them. As mtsw says, they like...
epanet-js
epanet-js is a new web application that combines modern web maps with the industry-standard EPANET hydraulic simulation algorithm. It’s for people planning and updating water utility systems: connecting pipes and pressures and figuring out what will happen. It’s a problem area that I’m totally fascinated by and know very little about. It’s made by the folks from Iterating - Luke Butler and Sam Payá, who are experts in the field.
If you’ve been following along with my blog and projects, you might notice something familiar about this screenshot of epanet-js:
Yep! A lifetime ago, I built a company and product called Placemark, which was a tool for creating and editing map...
Felinet
https://coopepys.org/helix-the-catch/embed/
On these very hot days the mind wanders about to compensate for the containment in the shadows and it’s only now as temperatures drop a little is there a moment to thread together some of those thoughts, which in the process uncovered previously unexpected connections.
The first of these is Felinet as featured on this HackADay page. After many years tracking so many fringe radio development projects this one slipped by until checking the title for this post! Electra surely has a hand in this but haven’t checked with her yet.
It’s been over a year since we all met up in...
Как я ставил Ubuntu на Xiaomi Redmibook Pro 16 2025
Прошло более шести лет с тех пор, как я пересел на MacOS. В целом, софтом и железом от Apple я доволен. Тем не менее, для моих задач Linux был бы чуть более удобен. А недавно я узнал о линейке ноутбуков Redmibook. Внешне это клоны MacBook’ов. Судя по информации в сети, на них прекрасно запускается Linux. «Как [...]
Кризис Муравьиной Мельницы
( Июнь 2025, idb@kiwiarxiv )
Датский физик-теоретик Йеспер Гримструп, проведя в научных исследованиях около четверти века, в итоге обнаружил, что занятия большинства его коллег-учёных сильно напоминают один известный природный феномен из жизни муравьёв.
Суть этого феномена, по-английски именуемого «ant mill» или «death spiral» (русские варианты: муравьиная мельница, карусель смерти, муравьеворот), заключается в том, что один или несколько муравьёв вдруг начинают почему-то бегать по замкнутому кругу, постепенно вовлекая в этот бесконечный цикл бесплодного движения всё больше и больше других муравьёв. Каждый такой муравей бегает по общему кругу до тех пор, пока не погибает от истощения, а муравьиное кружение в целом так и продолжает...
BusyBeaver(6) is really quite large
For overdetermined reasons, I’ve lately found the world an increasingly terrifying and depressing place. It’s gotten harder and harder to concentrate on research, or even popular science writing. Every so often, though, something breaks through that wakes my inner child, reminds me of why I fell in love with research thirty years ago, and helps me forget about the triumphantly strutting factions working to destroy everything I value.
Back in 2022, I reported an exciting advance in BusyBeaverology: namely, whereas we previously knew merely that BB(6) > 1036,534, Pavel Kropitz managed to show that
BB(6) > 1510.
For those tuning in...
“More ways to skin a cat”: Quacktion Time, The Wedding and Heal the Net – New participatory formats at The Pleasance Theatre
At The People Speak we have many strings to our bow. In May 2025 we had the opportunity to create brand new participatory structures at the Pleasance Theatre for The Critical Conversations series commissioned by Sage and Jester production company. The aim was to involve the audience in discussing misinformation, truth and build dialogue around different perspectives. We followed our principles of creating participatory performance:
Non-hierarchy: facilitators and participants are all equals Structure without content: the content is developed spontaneously by the participants using an accessible structure Co-creation: it is about creating performance collectivelyMikey as Brother Read-the-Room in ‘Heal the Net’ at The...
Raymond Laflamme (1960-2025)
Even with everything happening in the Middle East right now, even with (relatedly) everything happening in my own family (my wife and son sheltering in Tel Aviv as Iranian missiles rained down), even with all the rather ill-timed travel I’ve found myself doing as these events unfolded (Ecuador and the Galapagos and now STOC’2025 in Prague) … there’s been another thing, a huge one, weighing on my soul.
Ray Laflamme played a major role in launching the whole field of quantum computing and information, and also a major role in launching my own career. The world has lost him too...
Возрождение натурфилософии (Новости 11:11)
( Июнь 2025, idb@kiwiarxiv )
Прямо сейчас на стыке большой науки и высокой философии начинают происходить весьма интересные позитивные перемены. Пока что, правда, мало кто это замечает…
В последние дни мая американский Университет Джонса Хопкинса стал местом проведения одной примечательной и весьма представительной по участникам научной конференции, получившей название Natural Philosophy Symposium 2025.
Если цитировать организаторов мероприятия дословно, то они охарактеризовали свою затею следующим образом:
«Международный симпозиум по всем аспектам натуральной философии, включая доклады от философов и учёных самых разных областей. Фокус мероприятия сосредоточен на рубежах понимания — как понимания нас самих, так и вселенной на всех её масштабах. Совместные обсуждения этих тем поверх...
