The Future of Programming

A very interesting presentation: http://vimeo.com/71278954 by Bret Victor presented at Dropbox’s DBX conference on July 9, 2013.

My first feeling after I’ve seen it was really sad. Did we, programmers, really lost last 40 years ?

My second thought was slightly more optimistic. Maybe we didn’t lost those years at all ? Maybe we used it to learn limitation of “conservative” apprach. Maybe we used it to develop techniques and technologies to make all those “forgoten” principles economically cost effective ?

And most important conclusion – Never think that you really “know what you are doing” and never stop looking for other solutions.

Spring Security by example: securing methods

This is a part of a simple Spring Security tutorial:

1. Set up and form authentication
2. User in the backend (getting logged user, authentication, testing)
3. Securing web resources
4. Securing methods
5. OpenID (login via gmail)
6. OAuth2 (login via Facebook)
7. Writing on Facebook wall with Spring Social

Securing web resources is all nice and cool, but in a well designed application it's more natural to secure methods (for example on backend facade or even domain objects). While we may get away with role-based authorization in many intranet business applications, nobody will ever handle assigning roles to users in a public, free to use Internet service. We need authorization based on rules described in our domain.

For example: there is a service AlterStory, that allows cooperative writing of stories, where one user is a director (like a movie director), deciding which chapter proposed by other authors should make it to the final story.

The method for accepting chapters, looks like this:
