Framework Design Papers

Steven Clarke (a usability researcher here at Microsoft) has published a set of very interesting papers discussing the core concepts of framework usability.   

I thought I'd collect them for your reading pleasure...

1. Dr. Dobbs article on Measuring Api Usability which introduce our approach to measuring API usability.  (Updated link from original post ).

2. The Journal of Visual Languages and Computing (volume 17 issue number 4) has an article on the Cognitive Dimensions framework that includes a section on how we apply the framework and the personas at Microsoft.

3. A short paper presented recently at a workshop in Germany on End User Programming. The paper is a briefly describe the three developer personas we design for. [Associated slide deck]

4. A paper from the Cognitive Dimensions workshop at the IEEE conference on Visual Languages in 2005. It gives a very simple and brief overview of how we profile personas using the framework but doesn’t describe the personas in detail.

Brad.

Problem is host names cannot contain underscores.

This is a file link.

Please not _ in host name.

Raphael: I'm guessing this is a problem with your browser or proxy. I'm having no problems with that link.

Ok, thanks

I think problem is  in proxy.

I use Firefox, and IE does not open the link too.

Please could somebody mail to my inbox following files???

Definitely I cannot retrieve those files, I suppose organization proxy policies are causing this error to happen.

Please send files to:  justresearchman@gmail.com

Api usability is a critical issue during Api design.

Thanks

Thanks for collecting the links, Brad. Very helpful.

The underscore is definitely the problem, cf. to RFC1035 which does not allow underscores in domain names. Thus our proxy rejects access to brad_abrams.members.winisp.net due to "Invalid URL", as it states, and enumerates "Illegal character in hostname; underscores are not allowed" as a possible reason.

Hi Brad,

This link is in the ppt, but I cannot find it:

Thanks,

Same problem here too.

I get an "Invalid URL" error in IE7:

Some aspect of the requested URL is incorrect. Possible problems:

Missing or incorrect access protocol (should be `http://'' or similar)

Missing hostname

Illegal double-escape in the URL-Path

Illegal character in hostname; underscores are not allowed

If it is valid, can someone post the IP address?

TIA

André

Apparently nslookup returns the IP:

192.197.157.24

But the browser still refuses the URL.
