from code to UML (PlantUML) to diagrams

by Philip Durbin

Michael, I'm still thinking about your "draw more, code less" talk and today I got it in my head that a nice way to learn the PlantUML syntax might be to start with existing code (Java, in this case) and have a tool generate the PlantUML for me. I'm sure various IDE's might have a way to do this, but I figured I'd start with the command line: javadoc -private -quiet -J-DdestinationFile=abstract-classes.uml -J-DcreatePackages=false -J-DshowPublicMethods=true -J-DshowPublicConstructors=false -J-DshowPublicFields=true -doclet de.mallox.doclet.PlantUMLDoclet -docletpath ~/bin/plantUmlDoclet.jar -sourcepath . Duck.java FlyBehavior.java FlyNoWay.java FlyWithWings.java MallardDuck.java RubberDuck.java java -jar ~/bin/plantuml.jar -graphvizdot ~/bin/dot -t png abstract-classes.uml It works great! I'll attach a couple UML files and class diagrams. See also http://plantuml.com/doclet.html Phil p.s. Here's the source I'm operating on: https://gist.github.com/pdurbin/f2a34896377b6777acc6 On Sun, Jan 12, 2014 at 12:13 PM, Bar-sinai, Michael <mbarsinai(a)iq.harvard.edu> wrote: > > Hello everyone, > > The slides and code for Thursday talk (diagrams etc.), with some internal projects mentions removed, are available here: > http://www.mbarsinai.com/blog/2014/01/12/draw-more-work-less/ > > -- Michael > > (Thanks @philip_durbin for suggesting to post it) > _______________________________________________ > TechTalkFollowup mailing list > TechTalkFollowup(a)lists.iq.harvard.edu > > This list is shared with the public.

UML vs. TLA+

by Philip Durbin

I just listened to http://www.se-radio.net/2014/04/episode-203-leslie-lamport-on-distributed-s… and Leslie Lamport 's comparison of UML vs. his TLA+ system reminded me of Michael's talk about PlantUML. I don't think I can do TLA+ justice so it would be best to listen to the podcast above but I'd like to point to a practical use of TLA+ he mentioned at Amazon. According to https://groups.google.com/d/msg/tlaplus/C7Rmka3iSGE/zLQjQh0NeSEJ Chris Newcombe will soon be publishing a paper called "Why Amazon Chose TLA+". He goes on to say: "Part of my evaluation is already available, in a talk that I gave at HPTS (bi-annual workshop on High Performance Transaction Systems) in 2011 Slides including notes : http://hpts.ws/papers/2011/sessions_2011/Debugging.pdf Specifications for 2 'real world' algorithms for transaction isolation, in both Alloy and TLA+ : http://hpts.ws/papers/2011/sessions_2011/amazonbundle.tar.gz " His LinkedIn profile at http://www.linkedin.com/pub/chris-newcombe/1/a08/b33 says "Successfully introduced formal methods to Amazon, using Leslie Lamport's method (TLA+ and PlusCal)" That tarball has some interesting TLA+ examples (textbookSnapshotIsolation.tla and serializableSnapshotIsolation.tla, attached.) They're reminiscent of Michael's PlantUML examples but more rigorous and mathematical, I'd say... For more on TLA+ see http://research.microsoft.com/en-us/um/people/lamport/tla/tla.html Phil On Sun, Jan 12, 2014 at 12:13 PM, Bar-sinai, Michael <mbarsinai(a)iq.harvard.edu> wrote: > Hello everyone, > > The slides and code for Thursday talk (diagrams etc.), with some internal projects mentions removed, are available here: > http://www.mbarsinai.com/blog/2014/01/12/draw-more-work-less/ > > -- Michael > > (Thanks @philip_durbin for suggesting to post it) > _______________________________________________ > TechTalkFollowup mailing list > TechTalkFollowup(a)lists.iq.harvard.edu > > This list is shared with the public.

Re: [TechTalkFollowup] TechTalkFollowup Digest, Vol 7, Issue 3

by Quigley, Elizabeth

Hi Brad, I haven't done much with web standards for accessibility requirements but it is in the plan for Dataverse 4.0 Beta (dataverse-demo.iq.harvard.edu/) to make sure we are complying. I have met with a woman at HUIT who does a lot of accessibility testing for Harvard websites and applications. She informed me that they use WCAG guidelines: http://www.w3.org/WAI/intro/wcag The minimum is to have your product compliant with WCAG 1.0. Also, I'll be testing Dataverse 4.0 Beta with JAWS screen reader and Dragon speech recognition software, which are used here at Harvard, to see how WCAG 1.0 compliant it is. I believe, but could be wrong, that being WCAG 1.0 compliant would help with potential dyslexia problems. I'm not sure how user friendly it would be to have to know to switch to a dyslexic friendly format. Once I run testing on Dataverse 4.0 Beta, I could put together some of what was found to send out so everyone can see what types of issues are found. That might be useful. Hope this helps!

I was curious how much you deal with web standards. I spent a great deal of time formatting one specific webpage to be as standards-compliant /and/ accessible as possible, which meant following HTML5 and ARIA for the most part. They have a test tool here: http://wave.webaim.org/ but it doesn't cover everything. I learned that certain formatting can assist people with dyslexia, and there are guidelines to improve their user experience: http://www.bdadyslexia.org.uk/about-dyslexia/further-information/dyslexia-s… . I concluded that it would essentially require a separate CSS file, and a little JS maybe to allow users to switch between the two. But other wise doable I think. (Sadly I didn't quite get that far myself, and there doesn't seem to be any other guidelines for this.) Any thoughts on something like this? Are there other visual/neurological impairments that you've come across that websites can format for? Brad

Meta question: allow non-IQSS or non-Harvard members on this list?

by Philip Durbin

Chris Perry and I approve people who want to subscribe to (and be able to post to) this list and so far, since I've recognized all the names as IQSS people, I've approved them all, but I just noticed a request to join from a non-IQSS, non-Harvard individual with a title of "Computing Infrastructure Manager" from UC Berkeley. I don't know this person but I'm fine with letting him join in and participate. If I don't hear any objections, I'll approve the request next week but if anyone has any concerns, please say so. In general, I favor public discussion, as I mentioned in the first post to this list: https://lists.iq.harvard.edu/pipermail/techtalkfollowup/2013-May/000000.html Phil -- Philip Durbin Software Developer for http://thedata.org http://www.iq.harvard.edu/people/philip-durbin
