I recall The Gold-Bug contained an interesting puzzle.

*It worked great for the data set it was given

Feeling a bit miserable today? Jump on a bus, train or tube and get off 8-10 miles from home then walk back. Don't think about it. Just do it. Always works wonders. #ArtOfBreathing #mindfulness

My son just called the Fediverse 'the linux version of social media'.

Planning on using Professor Steve Dutch's Enumeration of Polyhedra page as a reference for a future post. Dutch enumerates polyhedra by number of facets through 9 (and looks into 10-sided polyhedra). My goal is to enumerate polytopes by number of of vertices (including dimension > 3). I'll […]

One of the big US election equipment vendors was just acquired. While this may be interesting industry/business news, it's not by itself particularly interesting election security news. With protocols like Risk Limiting Audits, we don't depend on the integrity of tally equipment (or their […]

DHS zeroed out $34 million in NYC antiterrorism funding by 9/30, but Trump didn’t find out until Gov. Hochul called him on October 5. (Among other things) https://www.emptywheel.net/2025/10/07/do-something-bitch-kristi-noem-dressed-russias-useful-idiot-up-to-cosplay-cbp/

If I understand the Homan thing correctly: - Last year, undercover FBI agents gave him a bribe, $50,000 in cash. - The plan was to wait and see whether he followed through with what he was bribed to do once he became part of the new Trump administration, which would strengthen the case. - But […]

Nebraska Sen. Ricketts supports an ICE detention center in McCook #Nebraska The name of the camp, Cornhusker Clink, made me think of Col. Klink, from the TV show Hogan's Heroes, who ran a Nazi POW camp. I used the AI program Face Fusion to combine Col […] [Original post on mastodon.online]

Celebrating our tenth anniversary of going car-free!

I was just thinking to myself "It would be good if #mastodon let you follow someone's original posts without seeing all the stuff they boost, which is not relevant to me". Then it occurred to me to look and see if it does ... and it does! Click on the person's username, then click the […]

Keep 'em coming Via Klasfeld: A federal judge blocked the Trump admin's attempt to end New York City's congestion tolling. U.S. District Judge Lewis Liman is a Trump appointee. https://storage.courtlistener.com/recap/gov.uscourts.nysd.637159/gov.uscourts.nysd.637159.129.0.pdf

In my line of work I hear a *lot* of phrases that boil down to "I'm not a mathsy person because I'm creative". The idea that mathematics is necessarily non-creative seems to be quite popular, but I don't think it's true. In fact, I think creativity is a key part of being a mathematician. I think […]

"Enhancing pedestrian routing in #openstreetmap by incorporating shade into route computations" https://www.openstreetmap.org/user/zorun/diary/406587

TIL: Hyphy is a word.

For n = 3, 4, or 5 it is possible to dissect a triangle (equivalently: any polygon) into convex n-gons. For n > 6 it is fairly straightforward to show that it's impossible, using the fact that the average degree of vertices of a planar graph is < 6. So it seems like the interesting case is n=6 […]

Achievement unlocked! Emailed the offices of the #BCNDP #BCCP #BCGreens and every elected MLA. A similar message as last week's to Municipal leaders/staff. Tweaked the message to emphasize the "BC Made" element in this time of a trade war with the USA. Bluesky […] [Original post on socialbc.ca]

One of my favourite bits of #maths #history#mathsis, in 1557, Robert Recorde (🏴󠁧󠁢󠁷󠁬󠁳󠁿) gets so fed up repeating the same thing over and over again that, in order... "to avoid the tediouse repetition of these woordes: is equalle to" ... he just gives up and invents the equals sign: = 🏛️🎓 […]

I’m heading out to Ashburn, London Co., VA - end of the Silver Line. I’ll jog back along the W&OD trail as far as I can & return to DC via Metro.
