Palestra: “Performance: Are Your Computers Fast Enough?”

Data e Local:   5 de maio,  15:00 h      sala L774 (Prédio Cardeal Leme)

Abstract: Many people think that their computer programs are “fast enough” simply because they get the answer in a reasonable period of time. But “speed” is often not the only measure of performance. Battery life in a phone is also important, as are various real-time characteristics.This talk will not only give you insight to why your programs may be wasting time and electrical power, but tell you what to do about it. It will also announce a new competition sponsored by Linaro which will work to make GNU/Linux better for everyone.

Seminário: Network Survivability and Polyhedral Analysis – A. Ridha Mahjoub

For the past few decades, combinatorial optimization techniques have shown to be powerful tools for formulating, analyzing and solving problems arising from practical decision situations. In particular, the polyhedral approach has been successfully applied for many well known NP-hard problems. The equivalence between separation and optimization has been behind a big development of this method.  The so-called « Branch and Cut » method, which is inspired from this equivalence, is now widely used for obtaining optimal and near-optimal solutions for hard combinatorial optimization problems. In this talk we present these methods, and discuss some applications to survivable network design models.

Palestra dia 10/04 às 16:00 na 511 RDC: How Developers Reason about Module Cohesion? – Cláudio Nogueira Sant’Anna (UFBA)

Título: How Developers Reason about Module Cohesion?
Palestrante: Cláudio Nogueira Sant’Anna (UFBA)

Abstract:

Several cohesion metrics have been proposed to support development and maintenance activities. The most traditional ones are the structural cohesion metrics, which rely on structural information in the source code. For instance, many of these metrics quantify cohesion based how methods and attributes are related to each other within a given module. Recently, conceptual cohesion metrics have been proposed for computing cohesion based on the responsibilities a given module realizes. Besides different flavors of cohesion, there is a lack of empirical evidence about how developers actually perceive cohesion and what kind of cohesion measurement aligns with developers’ perception. In this paper we fill this gap by empirically investigating developers opinion through a web-based survey, which involved 80 participants from 9 countries with different levels of programming experience. We found that: most of the developers are familiar with cohesion; and they perceive cohesion based on class responsibilities, thus associating more with conceptual cohesion measurement. These results support the claim that conceptual cohesion seems to be more intuitive and closer to the human-oriented view of software cohesion. Moreover, the results showed that conceptual cohesion measurement captures the developers’ notion of cohesion better than traditional structural cohesion measurement.
