Good job and thanks for sharing.

FYI: after pressing q or a keys, most of the time my firefox thinks I'm trying to execute a search on the page and thus prevents the next keypress to reach the document. Explicitly focusing an element on the page at each keypress and/or interrupting keypress propagation are possible fixes.

cheers

Re: How to Create an Erlang First Target System

Hi.

Thank for the tutorial, it works :)

Just one thing is strange: when I unpack FIRST.tar.gz, erts-5.7.2/bin/ contains start_erl.src instead of start_erl.

It's not a big deal, a rename and chmod +x and everything works, but still.. why?

Any idea? Thanks.

Glad to hear that.

If you feel like sharing your charting stuff, drop a line :)

A possible alternative to the sidecar file is to embed semantic hints in the markup, like microformats or RDFa.

While we wait for the mess to cleaned up, maybe this is useful: http://scraperwiki.com/

no, the idea is that after 100 levels of nesting you finally have a crappy element <tr>td>cool title</td></tr> that contains the title.
you just add attributes to specify its semantic meaning. The above in RDFa would be like

<tr><td property="dc:title">cool title</td></tr>

I think RDFa requires xhtml. In microformats, that would look like

<tr><td class="entry-title">cool title</td><tr>

The proposed hAtom microformat: http://microformats.org/wik...

@JeroenPulles E4X seems sexy, but have yet to dive into it. Thanks for the hint.

Hi Ivan,

yes, I passed the file path, the disqus key and forum name and I double checked the values were correct.

Tnx

Anergy,
you're right, should be a StringBuilder. Thanks for spotting it.

Hi Christian,
I've updated the post with your observation.

Thanks.

Hey Robert,
interesting observation:
Javadoc for java 1.4 says "String concatenation is implemented through
the StringBuffer class and its append method"
(http://download.oracle.com/...
While in java 1.5 it's "String concatenation is implemented through
the StringBuilder(or StringBuffer) class and its append method" (I've
updated the post)

It actually makes sense, as StringBuilder has been introduced as a
faster (non thread-safe) version of StringBuffer.

To answer your question, i think it's likely the JIT compiler finds
an opportunity for optimization in a concat loop, but I have no idea
on how to go at testing this, other than disabling the JIT and
comparing the results. Seems to be good material for an other post!

Thanks!

Forax,
apparently the option has been there since Java 6 Update 20. It would be interesting to see if the optimization happens during compile or JIT...

EDIT: javac does not accept that option, so it's sure a JIT optimization

Hi Pankaj,
I found really little information about the whole subject, but I will post some links in the next few days.

Thanks for your comment.
