lfest 0.0.2 Is Released

New Version of lfest Available

lfest 0.0.2 includes the addition of text-only responses in addition to the already-supported HTML and JSON responses. This addition was made in order to more readily support LFE web app developers writing for services such as Google App Engine that expect apps to implement particular resource endpoints (e.g., /_ah/health) which return plain-text responses.

Usability Update: IErlang Notebook (a la IPython)

Updated project source for IErlang makes it easier to use

Back in April, the Erlang community was stunned to hear that we had been given an answer to IPython, IHaskell, and IJulia – IErlang. However, as Robbie noted in the list of outstanding issues at the end of the IErlang demo notebook, not a lot of time had been set aside to develop a more standard project structure. Furthermore, the setup and installation of IErlang to get to the point where you could try it out was a rather arduous process. All of that has now changed …

ErlPort and Python Part II: Making More Calls from LFE

Part II of an Introduction to ErlPort with LFE

A short while ago, I did a teaser post about calling Python from LFE. There was only a tiny bit of code… but! It came with one of the best Erlang/Python pictures EVAR. You know which one I'm talking about.

ErlPort: Using Python from Erlang/LFE

A Quick Introduction to ErlPort via LFE

This post was originally featured on cogitat.io and is being reblogged here as an experiment. This repost is an adventure into GitHub pages as a blogging platform for code-heavy posts. For year, I have found Google's blogger.com cumbersome as a medium for sharing code. The burden has finally grown too great. It makes sense to use the same platform to share the prose description of code as that which shares the code itself (i.e., repositories and README files). I can only imagine this will be much less painful than creating gist code snippets and tweaking them in blogger. As a bonus, code should now appear in RSS/Atom feeds :-)

Erlang @ OSCON 2014

Updates from the conference ground zero

Even though there's no Erlang-specific booth (or a booth by an Erlang company), the Erlang OSCON presence has been palpable, albeit in a small-town, gentle way.

LFE Language Summit Review

A report on how the first LFE language 'summit' went

Erlang Factory was very kind to assist Robert Virding in setting up the first "language summit" for LFE here at Erlang User Conference in Stockholm. (We use the term "summit" playfully, since it's a very unofficial affair within a small developer community.)

The Secret History of LFE

A post to the mail list too good to just keep there :-)

When asked recently about the history of LFE on the LFE mail list, Robert replied with some nice information that we couldn't resist highlighting/duplicating here:
