2. OBJECTIVES
 Studies about the adoption of Version Control
Systems by EUs;
 Only studies aiming professional programmers were
found.
 Domain-Specific Languages;
 The use of community knowledge on EUSD.

3. DOMAIN-SPECIFIC LANGUAGES (DSLS)
 Different domains of knowledge have different
notations, tasks and goals.
 Domain experts need development tools that take
those differences into account.
 DSLs tend to facilitate coding, but can have
limited expressive power.

4. DOMAIN-SPECIFIC LANGUAGES (DSLS)
 Can be classified into three dimensions:
 Focus
 Vertical – Aims at a specific industry or field.
 Horizontal – Has broader applicability.
 Style
 Declarative – What to do.
 Imperative – How to do something.
 Notation
 Graphical
 Textual

5. COMMUNITY KNOWLEDGE
 Inexperienced users often rely on more
experienced programmers to solve problems;
 Reusability is important for EUs, specially those
involved with scientific programming;
 In this way, social networks can be very useful.

6. COMMUNITY KNOWLEDGE
 The use of online IDEs, such as Cloud9, opens up
opportunities for integration of social features.
 Error messages commonly are useless and do not
help the programmer to debug.
 Interesting project called HelpMeOut detect
errors and suggest solutions previously used in
similar problems.
 Limited prototype but the idea can be useful.
