Today I Learned

Great Pyramid of Giza, via Wikimedia Commons NOTE: An edited version of this article appeared on The Skeptic (UK). “The limits of my language mean the limits of my world.” Ludwig Wittgenstein, Tractatus Logico-Philosophicus, section 5.6 Language may be the most powerful tool we have, and I believe it must be used responsibly. But what is language? What’s a tool? What does it mean to use it responsibly? Such questions are deceptively simple, because “everyone knows” what langu

Hacker Silhouette, via Wikimedia Commons They want to help keep people safe. That’s a motivation I certainly support, but it’s important to be sure that your actions actually support your goal. On the 1-Dec-2025 episode of Cybersecurity Today, host David Shipley (whom I have mentioned before) talked about a new (at that time) website called Stop Hacklore! They describe themselves as “a group of current and former CISOs and security experts” who “want to offer guidance that ma

Cyclospora cayetanensis, via Wikimedia Commons I was surprised to learn that Waldo is actually Wally, and that he’s only been around since 1987. I first heard of him as an adult, but always assumed that he had been around for years before that period where he appeared to be everywhere. Just like Robert F Kennedy, about whom I have written several times. Most recently, I described the changes he made to the Food Pyramid, but I have also discussed his anti-vax views and his app

Charity meme, via www.rallycorp.com I sometimes find it useful to dig into assumptions, particularly when they are hiding in the “everyone knows...” category. While charity and philanthropy are related, most comparisons of the two words seem to focus on charity as a short-term provision of aid or support, and philanthropy as more strategic and focused on longer-term, systemic change. But when I started looking into how philanthropy is promoted, I found some interesting assump

Touched by His Noodly Appendage, parody of Michelangelo’s Creation of Adam, via Wikipedia.org Reactions to the above image range from religious ecstasy to abject horror. I find it amusing and interesting, so I guess I’m somewhere in the middle. The Flying Spaghetti Monster was, according to the consensus of scholarly opinion, a satire on creationism, created by Bobby Henderson, a physics graduate at Oregon State University. It was first published as an open letter to the Kans

Louis Armstrong, via Wikimedia Commons Louis Armstrong was one of the truly great musicians, and What a Wonderful World is one of the truly great songs. To get just a hint of his influence, have a look at his discography. Section 1 consists of releases on 78 and 45 rpm, released between 1923 (before either of my parents were born) and 1970 (when I was a toddler), while section 2 consists of LPs and EPs, released between 1944 and 1971. Absolutely unbelievable, and if you think

Scutum – Roman shield This is a shield. Not the one I wanted to show, but a shield nevertheless. I actually wanted to show an image of the coat of arms of Canada, even though it was created long after the point at which it might reasonably have been placed on an actual shield, but I stopped when I found a notice on the Governor General’s website stating that the heraldic emblems may not be reproduced without written consent. (I strongly suspect that my using that image would

Appointing incompetent loyalists, via Wikimedia Commons I’d really like to describe the Trump administration as an example of Weaponized Incompetence, but I really can’t. Intuitively, the term seems to fit, but it already has a definition in the psychological literature. Setting Trump aside for the moment, the term refers to strategically avoiding responsibility by pretending to be incapable so that someone else helps, takes over, or stops delegating tasks. Over time, the per

“Beware of the Leopard”, from Hitchhiker’s Guide to the Galaxy, via Wikimedia Commons In the classic scene from the Hitchhiker’s Guide to the Galaxy (I refer, of course, to the 1981 TV version), Arthur Dent confronts the person trying to bulldoze his house, who explains that the plans for the demolition had been placed on display. “On display? I eventually had to go down to the cellar.” “That’s the display department.” “With a torch.” “The lights had probably gone.” “So had t

Da Vinci sketch of the human brain and skull (c. 1510), via Wikimedia.org NOTE: An edited version of this article appeared on The Skeptic (UK). “No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of government except all those other forms that have been tried from time to time.” Winston Churchill, 11-Nov-1947 The term “neurodiversity” has been used in recent years to describe the natural variations in human neurolo

Bubbles, from Finding Nemo, via YouTube.com Finding Nemo was a great film, filled with endless references, sight-gags, and characters, making it the sort of movie you can watch again and again. Among the wonderful scenes is one with Bubbles (voiced by Stephen Root), who gets a bit... excited when he sees bubbles. As Gill says, “Fish aren’t meant to be in a box, kid. It does things to you.” But why would people be thinking so much about bubbles? It’s not as if we’re in the mid

til-technology.com When we hear music, there’s usually a go-to association, which can say a lot about the listener. Take, for example, Wagner’s famous Ride of the Valkyries, from Der Ring des Nibelungen (The Ring of the Nibelung). While I have heard it many times (in isolation, as I have never actually listened to a Wagner opera in its entirety), the version that my mind always goes to is the one in What’s Opera, Doc?, with the famous lines: “Kill da wabbit! Kill da wabbit! K

The Quantum Leap, via Wikipedia.org When I write, I often try to come up with two topics that are linked in some interesting way, and find it fun when the link is unexpected or particularly tenuous. The more unexpected the connection, the more fun it can be, particularly when I learn about something new. So, the first time I wrote about quantum computers and encryption, I discovered the band Mammút, through finding their song “Shore” while searching for more information about

PSEUDOSCIENCE: Human and animal physiognomies, via Wikipedia.org NOTE: An edited version of this article appeared on The Skeptic (UK). Computer science is science, right? It’s in the name. This is actually a topic of some debate. Is it a scientific discipline? An engineering discipline? A branch of mathematics? Yes. All of that, and more. Probably best to describe it as a “multi-disciplinary field” and note the intersection points with mathematics, cognitive science, linguist

Phrack, via https://phrack.org/ Language is constantly evolving, not only by time and location, but also because of usage and changing cultural associations. When I think of the word “manifesto”, the example which leaps to mind is the Communist Manifesto, obviously due to the title, but also because it is short and clearly laid out. Manifesto is defined as “a written statement declaring publicly the intentions, motives, or views of its issuer”, and such statements are general

Principles behind the Agile Manifesto Experience is learning the hard way that something won’t work, is harder than it looks, or will come back to haunt you. Learning from history is where you find that something didn’t work, was harder than it looked, or came back to haunt someone... and then you go ahead and do it again. The well-known quote that “history does not repeat itself, but it rhymes” is, of course, attributed to Mark Twain. Quotes like this can be very hard to tra

Minion Sculpture – Brisbane 2024, via Wikimedia Commons Minions have a wonderful combination of traits which make them both dangerous and sweet. They want to help, but usually end up creating more problems than they solve. It seems as if their purpose in life is to be the henchmen of a villain, but they’re comically bad at it – incompetent and easily distracted, though not evil. At times, they seem almost like old stereotypes of interns – eager, but inexperienced and a bit c

Cover of The Alan Parsons Project album, Pyramid, via Wikipedia.org The Alan Parsons Project is one of those acts where many people don’t “know the band”, but will recognize several songs, such as Eye in the Sky , or Prime Time . Those familiar with progressive rock from the 1970’s and 1980’s, on the other hand, likely know them well. The only official members were Alan Parsons and Eric Woolfson , augmented by a large group of session musicians who worked in various capacit

Fallen Caryatid Carrying Her Stone, Auguste Rodin, via Cleveland Museum of Art When I first read Stranger in a Strange Land , I was too young to fully understand much of it. Of course I only realized that when I read it again, several years later. Over the years, I have read the book a dozen or so times, and picked up a bit more each time. This is the nature of good books – you can read them again, and pick up something new. Sometimes, you pick up some subtlety in the story o
