Compared to last time
Ruby is still motoring ahead, but Python is showing noticeable growth too – it seems that Python is starting to attract more interest – this maybe due to interest falling away in Perl quite sharply, and also a definite negative trend in PHP.
Whats of interest?
There is one other trend that piqued my interest, and that was an up trend for Haskell. This not because I particularly see a use of Haskell for me, but because it points to the stirrings of interest in Concurrent Programming Languages – in this area I’m going to look into Erlang – which has it’s roots in the Telecommunications industry.
While it would be presumptuous to say that book sales are a hard coded indicator of market share, I think that I could argue effectively that book sales reflect “Market Attention” – meaning that they resonate with the collective consciousness of where programmers see their present needs/demands, and their future requirements.
