Erlang on O'Reilly's radar


Some numbers on computer language books from an O'Reilly article.

It says
Minor Programming Languages -- 1,000 - 9,999 units in 2007

So the news in this category is that Groovy came out of nowhere and moved quickly up the charts. SAS, and MATlab had nice growth. Erlang, Processing and Nxt-G had no units in 2006 and each sold a nice quantity in 2007. Remember from above, this is the language grouping that grew the most in 2007. More than 14k units were produced by this grouping in 2007 versus 2006.

Well is 14k units really 14,000 books (or pdfs) sold? If we look at the table

*Minor* U N I T S T I T L E S M A R K E T S H A R E
Language 2006
basic 10,660 9,374 10 7 1% 1%

groovy 210 4,791 2 3 0% 0%
matlab 2,565 4,602 10 15 0% 0%
assembly 4,727 3,762 14 13 0% 0%

latex 2,827 2,718 4 6 0% 0%
erlang 538 624 1 2 0% 0%
awk 3,031 2,572 3 2 0% 0%

lua 1,563 2,367 4 3 0% 0%

processing - 1,991 0 3 0% 0%
nxt-g - 1,659 0 1 0% 0%
lisp 2,085 1,593 7 5 0% 0%
tcl 2,052 1,588 4 5 0% 0%
scheme 1,199 1,271 5 7 0% 0%
haskell 416 1,268 2 4 0% 0%

it means that Erlang's "nice quantity" is attached to 624 sold books. That's too low. Either the number is wrong or unit means a larger number of books sold.

What's all this fuss about Erlang?

A nice short description of Erlang and its benefits from Joe Armstrong.

AIR/Flex meet Erlang

Your Bear just noticed a post on Erlang by Ted Patrick. This is interesting because Ted works for Adobe as AIR/Flex evangelist.

Obviously Your Bear is not the only one who thinks AIR (one of the hottest technologies for creating GUI desktop applications), Flex (the JavaScript sibling used for many modern web applications) and Erlang on the server would make a great combination. You'll see the usual suspects in the comment section of that post.

See these posts on ErlAMF too.

LFE: Lisp Flavoured Erlang

Robert Virding, one of the main contributors to Erlang, has come up with LFE (Lisp Flavoured Erlang) which seems to be a Lisp interpreter for Erlang. Robert wrote:
I have finally released LFE, Lisp Flavoured Erlang, which is a lisp syntax
front-end to the Erlang compiler. Code produced with it is compatible with
"normal" Erlang code.
Read the announcement.

Erlang Blog Spotting

Blogs dedicated to Erlang show up like mushrooms after rainfall, so Your Bear decided to list them here:


New book project: Practical Erlang

After the very friendly reception of Joe Armstrong's new Erlang book last year the climate for new Erlang books seemed good.

Alas the second book project which was announced, a project by Joel Reymont, was stopped.

Now the word got out on another book project, this time by Francesco Cesarini and Jan Henry Nyström of Erlang Training and Consulting, one of the few commercial players in the Erlang world. The project is called "Practical Erlang", the publisher is O'Reilly and involved too is Mike Loukides, editor of "Real World Haskell". Read more here.

Jan Henry's OTP course teaching was excellent, so Your Bear is looking forward to this book.

Ericsson Functional Programming Seminar

Ulf Wiger posted another great article on his blog, this time about a seminar on functional programming which was held at Ericsson on February 21st, 2008.

The list of speakers is indeed impressing:
  • Simon Peyton-Jones, Microsoft Research
  • Satnam Singh, Microsoft Research
  • John Hughes, Chalmers
  • John Launchbury, Galois
Ulf provides slides (pdf) and videos (flv) of the talks.

I have read some of the slides and it looks very interesting, e.g. Simon talking about
contracts and John Launchbury talking about the Galois company.
