About ROSEdu

ROSEdu is a community that brings together

people with passion for programming, open-

source software and IT.

At this point most ROSEdu members are

students at the Automatic Control and

Computers Faculty, University POLITEHNICA

of Bucharest. New members are welcome

regardless of their background.

Our belief is that everyone should benefit

from our projects and activities. This is why

everything we create uses an FOSS (Free and

Open Source Software) licensing system. The

copyright nevertheless belongs to the people

taking part at various ROSEdu projects.

Although many of our projects are related to

the university educational environment, other

kinds of projects may be created depending on

the preferences and needs of ROSEdu

members.

For any information regarding ROSEdu pleaseuse the Contact information at the end of this

booklet.

Team

ROSEdu consists of volunteers and enthusiasts

passionate about free/open-source software,

open technologies and communities.

Started as a community project in the spring

of 2007, ROSEdu is currently working on

becoming a fully-fledged non-profit

organization.

Most ROSEdu members are students at the

Automatic Control and Computers Faculty. At

this point there is no formal status defined,

such that a ROSEdu member is a person with

constant involvement in community activities.

Members of ROSEdu include (but are not

limited to): Alex Eftimie, Andrei Buhaiu, Vlad

Dogaru, Sergiu Iordache, Mihai Maruseac,

Andrei Soare, Lucian Grijincu, Daniel Rosner,

Mihai Dumitrache, Razvan Deaconescu, Lucian

Cojocar, Andrada Georgescu, Alex Juncu, Vali

3Projects

ROSEdu coordinates two types of activies:

open-source development projects community development

Most of the projects are focused on easing the

transition to an open-source development

environment (operating system, basic

applications, GUI, development tools).

We are trying to blend as much as possible the

fun/passion/enthusiasm factor with the

usefulness of a project. The development

projects are aimed at solving a particular

problem or optimizing certain aspects of day

to day activities.

Most of our activities take part under the

umbrella of the CS Department. Some projects

(WoUSO, Cspay, vmchecker) have been

integrated in educational or administration

activities of the department.

We are always open to new ideas and valueinitiative and involvement. A new interesting

project or activity is welcome as a ROSEdu

project even if it's not coming from a

community member.

ROSEdu Summer of Code is a frame project

whose aim is to give students an alternative

summer internship program. Students andenthusiasts can be a part of existing or new

ROSEdu projects.

We aim to help the participants become better

programmers and familiarize themselves with

the FOSS (Free and Open Source Software)

development environment and working in a

community.

As it name shows, the development

environment took its inspiration from Google

Summer of Code. Students may apply to one

of the projects presented on the dedicated

site. Development occurs during the summer

holiday but further collaboration is welcome.

This summer (2009) we will continue the

tradition and host RSoCv2. Many of RSoCv1s

projects year will be included and continued.

Hosted at RSoCv1 (2008 summer):

Hammerfall general purpose graphics

engine written in Python

VMChecker automated tool for

homework evaluation

WoUSO educational game for 1st year

students

CSpay administration tool for automating

the creation of salary documents

Tigus bar code test generator

ROSEdu summer of codeWorld of USO

WoUSO (World of USO) is an educational

game targeting students of the Operating

System Usage (OSU) course of the Automatic

Control and Computers faculty. It is meant to

encourage acquiring knowledge in an

educational and competitive mode.

The game, backed-up by an interesting and

captivating context story, is in its second year,

attracting over 100 students in the 2008-2009

academic year. The best students were givenspecial awards at the end of the competition.

WoUSO is being actively developed and will

continue into the 3rd version. The

technologies used are web specific: PHP,

MySQL, Smarty and XML.

WoUSO is a free open source software and is

distributed under an open source license. It

was awarded the first prize during the

Scientific Student Presentations of 2008.

ROSEdu


CSPay, one of the first projects developed at

ROSEdu, is an administration tool used for

automating the creation of salary documentsin University POLITEHNICA of Bucharest.

Its main software components were two

underlying libraries and a set of user interfaces

(CLI and WebUI).

CSPay was developed using C, PHP, Python,

and shell scripts. This was our first occasion to

learn how to use revision control systems and

mailing lists and how to work as a community.

The project was part of ROSEdu Summer of

Code during which it was restructured and

improved. CSPay is used by university staff at

the Automatic Control and Computers Faculty.

CSPayHammerfal Graphics Engine

The Hammerfall project aims at creating a

graphics engine using portable and open

source tools. Development and

implementation technologies include:

OpenGL, Python, SVN and Trac.

The project was launched over an year ago

and was part of the first edition of ROSEdu

Summer Of Code. This period was used for

establishing the projects baselines and

purpose. Development has continued to this

day and Hammerfall will be included in

ROSEdu Summer Of Code v2.

Our team consists of 1st, 2nd and 3rd year

students from the Automatic Control and

Computers Faculty, UPB.

The current goal is creating a generic graphics

engine that can be used in as many

applications as possible ranging from

simulators to computer games.

Automated homework evaluation increases

the assignment quality and educational

experience of the students. This alsoencourages students to create better

homework.

vmchecker is a scalable homework evaluating

framework that can be used for a wide range

of courses, enabling the evaluation of

homework that need complete administrative

rights on a system.

vmchecker is used to test homework for

several courses at the Computer Science

department in Politehnica University of

Bucharest: Compiler Course (java homework

for source code translation), Operating

Systems (C/C++ homework using

Linux/Windows syscalls), Operating System

Design (kernel drivers and modules needing

complete access on the system).

vmchecker was awarded the first prize during

the Scientific Student Presentations of 2009.

vmcheckerRobocheck

Robocheck is a software application designed

to verify the common problems found in

software written by young students.

Its mainly indented as an automated

homework tester for student-developed

software applications. Its target is

represented by teaching assistants that are

responsible for the verification and evaluation

of student homework, and by students who

want to evaluate and improve their coding

style.

The common software issues that the program

checks for include:

memory allocation problems

security vulnerabilities

static code analysis

synchronization problems

bad coding style and commenting

It is based on various Linux utilities designed

to verify different coding problems, and the

final result can be seen as a tool for

performing multiple test suites. The test suites

use tools like valgrind, splint, electric fence or

mcheck.

For the time being, the program only checks C

based homework, but it will be expanded in

the future to support other programming

languages.

The user interface is a command-line

interface, designed to be integrated with other

shell based homework evaluation software.

Xpresso is a project with the primary goal of

offering an automated tool for drawing logical

circuits starting from a natural or Verliogdescription.

The program is intended to design the circuits

while taking into account numerous design

restrictions: types of gates, number of gates,

surface area covered, total cost of physical

implementation, and others.

Xpresso receives on input a description that is

either Verliog based, or algebra formulas

based, and returns an SVG based image of the

actual circuit (with conventional drawn logical

gates).

Within RSoC 2008, Xpresso was developed as

a first version prototype. During RSoC 2009,

based on the previous implementation

experience, the code was mostly rewritten in a

much more scalable and robust version. The

software is developed in Haskell, and uses GTK

for the graphical interface.

XpressoEDSS

Drawing neat and clean electrical circuits for

educational proposes has always bean a

challenge, as most commercial solutions are

designed for corporate usage.

We decided to build our own Electrical Design

and Simulation Software, custom developed to

meet our demands.

The application is developed in Java, so as to

be as mobile as possible, and was used SVG to

have scalable and flexible drawings.

The first stage of implementation was

included in RSoC 2009. In this first stage, we

built the drawing and model components.

Presently, the application allows the user to

draw basic electric diagrams, save them in SVG

and PDF format, and modify them. The user

has at his disposal an initial library with about

100 basic electrical components.

Currently, we are working on the last details inthe drawing module, and will soon start work

on the simulation modules.

4Events

ROSEdu is built around the idea of an active

community assembled from enthusiastic

people, and it is constantly growing andadapting to the reality of the global open

source community.

As one of our primary goals is to promote

open source code and to bring to this

community new people interested in using

and developing open source projects.

One way of achieving this goal is by organizing

various events, either social based, either

centered on promoting open source software

as well as offering hands on support for

installing and initial configuration of operating

systems, developing tools, and other general

use open source projects.

Ubuntu Install Fest

One of the first community events that

ROSEdu organized was Ubuntu Install Fest. We

have coordinated two Ubuntu Install Fests

following the same recipe used by other

Ubuntu Communities.

The main target group were freshmen and

people new to Ubuntu and open-source

technologies, but the initiative was open to

everyone.

Although Ubuntu was the primary distribution

used for installation and configuration, weprovided support for other distributions as

well.

11

Social Thingie

We all need a little R&R every now and then.

ROSEdu Social Thingie is focused on the more

social part of a community.

All work and no play makes John a robotic

programmer, and we dont want that at

ROSEdu. We want to include as much fun and

passion both in our projects and also other

activities. A little bit of fun is particularly

useful for team building and community

binding.

After two successful editions we decided to

organize Social Thingie events on a regular

basis. So far social activities included bowling,

air hockey and other games we consider fun.

The Open Source Development Course is an 8

week event consisting of various activities

(courses, hackathons, application based

workshops) for students at the University

Politehnica of Bucharest. It focuses on useful

open source development tools and working

in an open source community.

At its first year, the course was attended by 16

students (around 80 students applied). It was

divided in two components:

a course during which theoretical

knowledge about working on a project is

presented

a workshop where students learn practical

skills of using open-source tools

The course aims at preparing students for their

first experience with free/open-source

applications and communities.
