2024 Ok I’m still playing catch up. Many of these I read some months ago. I’m unsure in which order but I start off as usual with a re-reading of: Tender is the Night F. Scott Fitzgerald Which I enjoyed more than ever and indeed am now convinced that this is his greatest novel. I loved the opening prose so much that I picked it up a few weeks later …

At the ultimate point Where extinguishing flips A cold switch, chilling dip And the lights go out One by one, one by one: Each a picture, each an image Of people, person, place; The furnishing awareness Dusted with half-remembering, Dissolves into people, person, place: The milliseconds of the only movie I ever made But never could publish Subsists for me alone: mon oeuvre Unique et solitaire: ma vie. The loves …

This week in Modern Plain Text Computing we put together some of the things we’ve been learning about cleaning and tidying data. Here’s a somewhat sobering example using data from the Fatality Analysis Reporting System, which is how the NTSA tracks information about road accidents in the United States. Our data file shows counts of pedestrians aged <16 killed in road accidents on each day of the month in the …

I was thinking earlier today that I haven’t posted here in a while. I also have been thinking that I should worry less about publishing finished ideas, as I frequently tail off before that point. Then, the idea goes, forgotten, forever. So why not plant that seed here? It will go unnurtured but at least it can get a couple roots down, to let it weather the storm of amnesty …

Got a question, suggestion, correction? Let me know!

After taking a long break from working on belief systems(and writing a book in the meantime), I think it’s time to get back to belief system. The problem that got me stuck was how to define the term ‘Belief Systems’. The concept is not new(the oldest usage I could find goes all the way back to Plato and his...

$\newcommand\C{\mathbb{C}}$ I came up with the proof below while preparing a lecture for my complex analysis course. I learned from Sinan Gunturk that Peter Lax showed him the same proof back in 2007. Let \(O\subset\C\) be open and convex. Let \(z_0 \in O\) and \(c: [0,1] \rightarrow O\) be a closed piecewise \(C^1\) curve. Recall that the winding number of $c$ around $z_0$ is defined to be \[ W(c,z_0) = …

After several years of keeping it going in semi-retired, keep-the-lights-on (KTLO) mode, I’ve decided to officially fully retire this blog. The ribbonfarm.com domain and all links will remain active, but there will be no new content after November 13th, 2024, which happens to be my 50th birthday. There will be one final roundup post before […]

What will affect the earth’s temperature the most in the next 10 years?Aerosols“Aerosols” is a fancy name for “tiny particles in the air”. Aerosols are the most potent climate lever in the world, because they act near instantly.Some aerosols warm the planet, for example, soot (‘black carbon’). Some aerosols cool the planet, for example, sulfur dioxide.CO2 and methane have to accumulate for decades to cause the warming impact shown above. …

I’m not technically a boardgame designer, but I will be at the Hythe Community Games Day on Saturday 9 November taking place inside St. Leonard’s Church in Kent. I’ll mainly be hanging out by the Frostgrave table run by some friends. I expect it to … Continue reading →

(One of my summaries of the one-day Pycon NL conference in Utrecht, NL). Brett is the writer of the effective python book. As an example, he picked a calculator that can add and multiply integers. The numbers, the operators: everything is an object in his example. You can do it with one big function, object oriented or with dynamic dispatch. One big function: just a big old recursive function with …
