slidesharing
just played a bit with slideshare, where I uploaded my march presentation at the TLUG :
notes to self :
- the first page should be the title page (but I like to have a blank page while people arrive / gather)
- too much bullets
- がんばります。。。
in general :
- sharing slides != presenting them
Slideshare is nice. Reminds of that very interesting blog post about PowerPoint battle plans.
talking at the tlug, the movie
The video of my presentation of OpenWFEru at the Tokyo Linux User Group is available now (along with the excellent presentation of Edmund Edgar about Second Life).
The slides are available as well (without my funny swiss accent).
Many thanks to the TLUG guys for the opportunity.
Cyclo Saikuro
Yesterday evening was the revival of Ninjava, a gathering of programming enthusiasts (not only Java) in the Tokyo area.
Zev Blut presented one of his open source projects : Saikuro.
“Saikuro” is a japanese transliteration of “Cyclo”. This tool analyses a set of ruby code and outputs a report about its “cyclomatic complexity”.
In short, this metric looks at how many branches there are in a piece of code and returns a complexity score.
In this example, the complexity is “3″ : the easy way to compute the metric is by counting how many areas are “encircled” by the graph representing the code (plus the area surrounding the graph).
Pointers to articles about that metric are available from Saikuro’s home page.
I ran Saikuro over my OpenWFEru project. Saikuro generated two reports, one about Cyclomatic Complexity and one about the count of tokens per line.
For OpenWFEru the very first written methods (the one dealing with interfacing with the Java engine over REST) were flagged in red. As Zev pointed out, such ‘parsing’ code sports loads of ‘ifs’ and thus yields a high CC score.
To the reports.
At the end of the talk, the discussions centered on the usefulness of the metric for a developer and especially a project manager, and on how to integrate it in a development process. (check in, code review, …)
It’s a simple and effective metric, nice addition to a Ruby toolboox. This utility deserves to be gemified.
It would be nice if the reports actually displayed the methods (at least the ones in the red), maybe with a bit of Erb and a ruby.css…
Emerson Mills will talk about “agile software development process” (”scrum à la Mills” as he said) in the next (April) meeting of Ninjava.
Thanks to the Cerego guys for hosting this meeting !
talking at the tlug
I’ll be talking about OpenWFEru, Ruby workflow and BPM (technical point of view) tomorrow afternoon at the TLUG technical meeting of march.
Thanks to Zev and his team for this lively Linux User Group they are supporting.
sqs & s3
I just attended a technical meeting of the Tokyo Linux User group. Emerson Mills of Amazon Web Services talked about SQS and S3. He also talked about the Elastic Computing Cloud and the Mechanical Turk.
Since I first learnt about the Simple Queue Service, I wanted to build an OpenWFE adapter for it, this service might be ideal as a base for a worklist. The Simple Storage Service on the other hand would be suitable for a document management system (DMS), maybe some versioning and locking would have to be added on top of it, but well, the hard work has already been done by Amazon.
Workflow + DMS persisted in Amazon services… Only the transient things would run on their own servers, and those servers could be Elastic provided.
