Good Math, Bad Math

Latest / page 2

A little bit of knowledge is a dangerous thing. There’s no shortage of stupidity in the world. And, alas, it comes in many, many different kinds. Among the ones that bug me, pretty much the worst is the stupidity that comes from believing that you know something that you don’t. This is particularly dangerous for…

This past weekend, my friend Orac sent me a link to an interesting piece of bad math. One of Orac’s big interest is vaccination and anti-vaccinationists. The piece is a newsletter by a group calling itself the “Sound Choice Pharmaceutical Institute” (SCPI), which purports to show a link between vaccinations and autism. But instead of…

A while ago, I wrote a couple of posts that claimed to talk about finger trees. Unfortunately, I really botched it. I’d read a bunch of data structure papers, and managed to get myself thoroughly scrambled. What I wrote about was distantly related to finger trees, and it was useful to help understand how fingertrees…

Stellardrive, Inlandsix: Reasonably good instrumental prog. They’re not particularly exceptional, but they’re decent. Gong, “The Octave Doctors and the Crystal Machine”: Gong is a perfect example of one of the differences between the great prog bands, and a lot of the neo-progressive stuff. I can’t quite describe exactly what it is – but you listen…

Book Update

Very quick post here: the third beta of my AppEngine book “Code in the Cloud” was released this morning. If you’ve bought a copy of the beta, you can go to your pragmatic account, and download a fresh copy with all of the fixes and new material. If you haven’t bought a copy… Well, if…

Against my better judgement, I’ve ended up writing a lot about the financial mess that we’re currently going through. If you’ve read that, you know that my opinion is that the mess amounts to a giant pile of fraud. But even having spent so much time reading and studying what was going on, the latest…

I am a racist

(Unfortunately, this post has been linked to by a white supremacist site. Instead of providing a forum for their foulness, I’m shutting down comments on this post.) Unfortunately, I lost the link that inspired this. But I recently saw a post by a conservative about “reclaiming” the word racist. It went on to list a…

I’m glad to report that electricity has been restored to the Chu-Carroll household. So now I’m trying to catch up. During the outage, I got a bunch of questions about the latest news coming out of the big financial disasters. A major report came out about the failure of Lehman Brothers, and one thing that’s…

As I’ve mentioned before, I’ve been spending a lot of time working on a book. Initially, I was working on a book made up of a collection of material from blog posts; along the way, I got diverted, and ended up writing a book about cloud computing using Google’s AppEngine tools. The book isn’t finished,…

A bunch of people have been asking me to take a look at yet another piece of Cantor crankery recently posted to Arxiv. In general, I’m sick and tired of Cantor crankery – it’s been occupying much too much space on this blog lately. But this one is a real prize. It’s an approach that…
