More SOE blogs

Apocalisp, who is also working through SOE, pointed out his new blog on the subject, yay!

Lambdacamels, slime, and a syphilitic stoat.

1. In which a challenge is thrown, but there is a spanner in the works! Haskell suddenly became “important” in the Perl community when Audrey Tang started to blog about Pugs, the prototype version of the Perl 6 interpreter/compiler. So, when I started looking at Haskell, I did so with another Perl-monger, larsen, one of […]

Trigonometry reprise

I whined on IRC about my inability to do simple trig and dakkar kindly took me through the basics of a cosine. So I sat down later to look again at an exercise I'd skipped: 2.2 to defined the function: > regularPolygon :: Int -> Side -> Shape> But I realised that I still couldn't […]

Chapter 3. SOE

If I found the exercises in chapter 2 a little hard, the fact that thereare only two of them in this chapter should have been a warning… Amusingly, Hudak suggests that the module SOEGraphics will notevolve, as it is designed for the textbook, however, as it happens, ithas changed its API in a significant way […]

Notes on Chapter 2 of SOE

Hello Planet A couple of weeks back, I got an email from Antti-Juhani who'd just processedmy request to have this blog added to planet Haskell.  He pointed outthat I seemed to have gone awfully quiet…  Basically, not had a lot oftuits recently, but now I'm working through SOE a bit more seriously,here are my notes […]

On learning Haskell

Haskell recently became trendy in the Perl community after Audrey Tangprototyped a compiler for Perl 6 at an incredible pace.  With this levelof interest, and the frequent exhortation to "learn a new programminglanguage every year", I decided to learn it. It's slightly more difficult than it sounds.  Occasionally you hearpeople saying that Haskell is easy […]
