Haskell
I read an article recently about how amazingly efficient functional programming, and Haskell in particular is. So I thought I’s give it a go and see how I got on. You can try it out in your browser: http://tryhaskell.org λ let factorial n = product [1..n] in factorial 99 9332621544394415268169923885626670049071596826438162146859 2963895217599993229915608941463976156518286253697920827223 7582511852109168640000000000000000000000 :: (Enum a, Num a) => a λ Pretty impressive! So I thought I’d try a simple web application.

When I first set up this web site, I looked for a simple web analytics program so that I could see if anyone actually looked at it. After faffing about with a couple of well known open source packages, I decided that they were way over the top by several orders of magnitude. Then I found SlimStat. However it appears to be no longer actively maintained, which it why the previous link is via the Way Back Machine.

When I got my Pi some months ago I bought a wifi adapter for it, as you do. But I couldn’t get it to work reliably in Raspbian, and I didn’t even try in Arch Linux. So I tested the adapter on my windoze box, and it worked just fine, and I tried it with Linux and it worked just fine, so I put it in the ‘too hard’ box.

I’ve studiously avoided Python up till now, even though it appears to be fairly popular, because it violates the first law of compiler design: ‘Blank space shalt not be significant except to separate tokens where necessary.’. That’s why you can minimise a lengthy JavaScript script like jQuery to one enormously long line and it still works just fine. But, she-who-shall-be-ignored (self categorisation) decided she wanted to enter an advent calender competition which involved checking a web page to see if your name has come up and sending an email if it does.

Introduction Whatever-o-meter is a WordPress and Hugo plugin that shows a tachometer-like dial with a pointer, asks a series of predefined questions which are answered by moving a slider, shows one of several predefined results, and moves the tacho pointer to a position determined by the value of the result. The project is on Github. Documentation Whatever-o-meter uses the shortcode [whatever-o-meter] or {{<whatever-o-meter>}} to insert the whatever-o-meter display into the page.
