SAML Holder-of-Key SSO Profile Handler

Today I updated the wiki on the SAML Holder-of-Key GSoC project. For those of you not familiar with the project, during the last few months I implemented a Holder-of-Key Single Sign-On profile handler for a SAML Identity Provider (the Shibboleth IdP). With this profile handler, a Shibboleth IdP can issue holder-of-key SAML assertions to property authenticated non-browser users.

In this scenario, a non-browser client (in my implementation, an HTTP User Agent written in Java) issues a SAML Request and sends it together with a self-signed X.509 certificate to the SAML IdP. The user behind the User Agent authenticates to the IdP with a username/password via HTTP basic auth. The IdP binds the key in the certificate to the SAML holder-of-key assertion, signs it and returns it to the User Agent. A demo of this message exchange is hosted at NCSA. Instructions for how to build and install the Holder-of-Key SSO profile handler are available at the project wiki. Any comments are most welcome.

As we approach the official end of the program, I must say it has been very exciting to work with Globus. The Globus developer community is friendly and helpful at all times. Also, Tom Scavo is the perfect mentor: he gives me freedom to be creative and proper guidance so I don't deviate too much from the right path :-)

gRavix service composition UI prototype

I just posted about the seeding of the gRavix gsoc svn repository, and thought I could follow up with a quick note on what this is built to accomplish in the long run, as well as give everyone a screenshot of what it looks like.

The idea is very simple - discover services which have already been deployed and use their different operations in order to compose a new, more complex workflow service. A simple idea, with potentially powerful outcomes.


What you see here is a filetree on the left which would be populated with both local (user owned) services and discovered (cloud) services, which can be dragged and dropped onto a new service in order to create a workflow.

Comments, suggestions and ideas are most welcome! And if you want help with getting it working, check out my previous post or just shoot me an email (narcvs@gmail.com).

SVN repo seeded with gRavix

I have seeded the Globus svn repository for the gsoc projects with a gravix repository. It is currently empty, but a first prototype should be in the "prototype" directory before the day ends.

Check out development at any point at http://svn.globus.org/repos/gsoc/gravix/.

It should be pretty straight forward to get it running by just pointing your browser to the index file, but more specific instructions will come up soon enough as well.

Update: Get a look at the first service composition UI prototype with:

svn co http://svn.globus.org/repos/gsoc/gravix/prototypes/gravix-proto-graph-1.0/

Then point your browser to gravix-proto-graph-1.0/index.html.

woo woo first commit! and first impressions.

I have just committed the first contribution from Milena who is working on type checking for Swift.

For what ended up as a very simple change (11 lines of pretty simple code) it has taken quite a long time to get it into our SVN - the basic code was written some weeks ago (before the official start) but we've had plenty of fun since then getting test cases to pass (this year I seem to be tripping on test cases more than I have in the past) and the like - new-to-the-project developer things that we won't have to do again for the rest of the summer.

I've helped mentor students before, but always students that "belong" to one academic researcher or another; it is an interesting and refreshing change to have a student working on a project that I suggested, rather than be supporting somebody else's project.

So I am pleased.

Diagnostic Administrator Interface Framework

Hello!

I'm Karl Norby, and I am current a second year undergraduate CS major at the University of Chicago. I will be working with Charles Bacon as my mentor on a Diagnostic Administrator Interface Framework, which should make configuration much simpler.

I keep a blog, which is not specific to this project, but I am sure to update it with my progress.

If you would like to get in touch, you can try my on gTalk (karl.norby {--at--} gmail {**dot**} com), on the MUD, or:

• my personal site

It should be a fun summer; I look forward to working with you all. Good luck to all!

Development of dynamic resource trading service for Virtual Workspaces

Hi,

First of all I would like to congratulate all accepted students !

I am Artem Harutyunyan, a first year PhD student at the Department of Computer Systems and Informatics at State Engineering University of Armenia in Yerevan, Armenia. My mentor is Tim Freeman and I will be working on the development of dynamic resource trading service for Virtual Workspaces.

I have set up a blog here, it's currently empty ;) , but I am planning to write there about the progress of my work, as well as other interesting technical stuff I will come around, so check it out from time to time :).

Needless to say, that I am very happy to be the part of community, and I hope to know everyone better. Feel free to drop me a line at hartem[at]gmail.com, alternatively one contact me via MSN or Jabber (ID's are the same as my email).

Here are links to my profiles on LinkedIn and Faceebook.

Cheers and fruitful coding,
Artem.

Type Checking and Inference for SwiftScript

Hi there!

I am Milena Nikolic, a CS student at the Faculty of Electronic Engineering, University of Nis, Serbia. I will be working with Ben Clifford as a mentor on Type Checking and Inference for SwiftScript. 

I am really thrilled about this project because I have major interest in grammars and compilers. Also I am happy I'll be working with this community during summer!

If you have any comment/idea/anything about my project or anything else please contact me via mail, IM or MUD. Here are some links more:

- My homepage, unfortunately in Serbian

- My Facebook profile
