2 likes•9,163 views
Developers are knowledge workers, not just encoders or typists. Coding is just a small part of software development, which is primarily about understanding people and business needs. Modern programming requires knowledge of multiple languages and technologies, and developers will use existing packages rather than writing all code themselves.

The document also covers challenges and lessons learned with adopting XP.
software myths
The document discusses several common myths about software engineering. It presents myths such as the idea that requirements can easily be changed, that adding more programmers will solve scheduling problems, and that coding is the major effort. For each myth, it provides the reality, such as how requirement changes often degrade software, coordination gets harder with more programmers, and coding is usually only 10% of the effort while other post-delivery activities account for 50-70% of the work. The document advocates for formal reviews, documentation, and a team approach rather than relying on individuals.
Software Myths
The document discusses several common software development myths. It is written by a group of 7 software engineers. The myths discussed include: 1) that clients know exactly what they want, 2) that requirements are fixed, 3) that quality can't be assessed until a program is running, 4) that adding more people fixes schedule slips, 5) that security is only a cryptography problem, 6) that a tester's only task is to find bugs, 7) that testing can't begin until development is fully complete, and 8) that network defenses alone can provide protection. The document aims to dispel these myths and provide more accurate perspectives.
Got Myth? Myths in Software Engineering
The document summarizes a working session on software engineering myths held on October 4, 2007 in Paris. The session included discussions of common myths in areas such as complexity, bugs, clones, aspect-oriented programming, and project management. Participants shared and debated myths in small group discussions. Some examples of myths discussed include the ideas that complexity leads to more bugs, clones are always bad, and aspect-oriented programs are inherently easier to maintain. The session aimed to evaluate whether such perceptions are truly myths or if aspects of them have been found to hold true in various studies.
Myths in Software Requirements
Sheraz Pervaiz will present on myths in software requirements. He has over 14 years of experience working in various roles in software development. Common myths include clients fully knowing their requirements, requirements being fixed, and one solution fitting all problems. Specific myths to be covered are that clients know everything, requirements are now fully known after initial meetings, requirements will not change during the project, assumptions can replace explicitly stating requirements, and there is a single definition of what makes a good requirement. The presentation will be followed by a Q&A section. Future presentations in this series will focus on handling myths and the relationship between myths and project management.
introduction to software enginering
Software engineering is an engineering discipline that applies scientific principles and methods to the development of software. It aims to deliver reliable and efficient software on time and within budget by defining processes and procedures. The need for software engineering has arisen due to factors like increasing changes in user requirements and environments, large and complex software projects, ensuring scalability and cost-effectiveness, and managing quality.

Introduction to software Engineering
Software is ubiquitous in modern society and can have huge impacts, both positive and negative. However, simply programming a software is not enough - software engineering principles must be followed to develop reliable, high-quality software that meets customer needs. Some common software development issues include not fulfilling customer requirements, being difficult to improve or extend, and lacking documentation. Following a systematic process involving requirements analysis, design, implementation, testing, and maintenance can help address these issues and produce software delivered on time and budget that works as intended.

This document summarizes a study on developers' motivation to document code. Through interviews and surveys, researchers identified hindering and motivating factors for code documentation. Hindering factors included documentation being tedious, difficult, time-consuming, and interrupting coding work. Motivating factors included documentation improving code comprehensibility, order, and quality. The researchers propose designing a solution to encourage documentation by emphasizing motivating factors and mitigating hindering ones. They plan to further validate findings through a quantitative questionnaire. The goal is to increase developers' internal motivation to document code.

Five essential elements for successful software development
This presentation explains the overview of Five Essential Elements for Successful Software Development.
Let's review it: What designers can learn from (code) review
What if designers approached collaboration and critique more like developers? Could it make us better designers, and could it better collaboration between designers and developers? Presented at Yggdrasil 2018 in Sandefjord, Norway
Code review at large scale
When you work in a small collocated team many engineering practices and approaches are relatively easy to use and adapt. In large project with many teams working on the same product this task is not so simple. I want to share experience report in implementing Code Review practice in big product development team (more than 150 people, 10+ feature teams). In this talk we will review what approaches works in such setup and what don’t work, what tools and additional practices are needed to support Code Review and make it more effective, what difficulties and blockers will you probably see in the real life cases, what useful metrics could be produced by this practice.
DevOps Challenges and Mitigation
This document discusses challenges organizations may face when implementing DevOps and proposes mitigations. The key challenges covered are: 1) Having separate DevOps and SRE teams instead of integrating roles, 2) Prioritizing feature development over DevOps responsibilities like quality and responsiveness, and 3) Collecting too many meaningless metrics and logs without proper use cases. The document recommends rotating team members, empowering SRE, maintaining a DevOps backlog, evaluating metrics per feature, and designing metrics and data retention with proper use cases and regulations in mind. In conclusion, the document emphasizes focusing on DevOps principles and engineering rigor over specific tools.

SFScon19 - Riccardo Felluga Andrea Janes - Personas-Driven Approach to Test C...South Tyrol Free Software Conference
Testing a software product is an essential part of the development process. The tests have the goal to improve/optimize defined quality attributes of the product. Unfortunately, sometimes software is developed based on the needs of a single programmer or just because a recent technology enables new product developments, and later—once a prototype is available—the question arises for whom this product might be interesting. In such cases, it is difficult to develop the appropriate requirements that best fit the needs of the final user.
In this talk we describe a personas-driven testing approach, which derives personas based on an initial product idea. Based on the derived personas, we define requirements and tests to guide the further development of the product.
The talk will present a case study in which we applied the method: from the initial prototype, we derive four personas that use the prototype in various ways, we extract requirements and tests.Test Driven Development
Test-driven development allows developers to find and fix bugs more quickly by writing automated tests before developing code. This reduces debugging time and improves productivity. Constant testing is crucial for short release cycles and gives developers confidence to refactor and improve code quality throughout development. Automated testing enables developers to test thoroughly without losing focus.

This document summarizes the rules and values of the Extreme Programming (XP) software development methodology. It outlines the core practices of XP which include planning with user stories, managing through daily stand-up meetings, designing for simplicity, coding with pair programming and unit testing, and testing all code through automated unit tests and acceptance tests. The values that XP is based on are also summarized as simplicity, communication, feedback, respect, and courage.

This document is a presentation about design engineering given at the Swift Conf in Cologne, Germany. It discusses:
1. What design engineering is, which combines traditional design, design thinking, and computational design by encoding design decisions using computer code.
2. The philosophy of design engineering, which is that the human experience, not the code itself, should be the focus. Speeding up iteration cycles by reducing steps in the process is also important.
3. How to create a culture of rapid prototyping where design works directly with engineering to find people who build as part of the design process and remove unnecessary steps.

Specification Of The Programming Language Of Java
- First generation languages are machine languages that use binary code directly, requiring programmers to manipulate toggle switches to program computers in the 1940s-1950s. This allowed for very efficient execution but made programs difficult to write and fix errors in.
- Programming languages have evolved through 5 generations, with each generation bringing programming to a higher level of abstraction and easier use for humans. Early generations used machine language directly while later ones introduced assembly languages, high-level languages, and object-oriented languages.
- The passage discusses first generation machine languages as the lowest level, directly using binary for computation on early computers without compilers or assemblers yet. This allowed for

Version Control with Git for Beginners
This document provides instructions on installing and using basic version control functionality with Git. It covers downloading and verifying Git installation, initializing and committing to a Git repository, viewing commit history and file status, staging and unstaging files, reverting and resetting commits, and tagging commits. The key points are initializing a Git repository, making commits to track changes over time, and various commands to move between commits, view history, and recover from mistakes.
Rails is Easy*
The document provides an overview of the history and evolution of the Rails web framework from 2006 to 2013. It discusses how Rails initially aimed to make web development "easy" but this led to issues with code quality. It then outlines how conventions and best practices developed over time to structure Rails applications according to the MVC pattern and provide guidance on testing, deployment and other aspects of developing with Rails. The document also notes that many advanced Rails topics were not covered.
Things Future IT Students Should Know (But Don't)
The document discusses what future IT students should know about their field of study and career. It emphasizes that the goal of an IT degree is to learn how to solve human problems using computers. It stresses developing strong problem-solving, communication, and social skills which are more important than specific technical skills. Companies hire based on an individual's ability to solve problems rather than their particular degree. The document advises students to gain experience through projects, explore new technologies, and collaborate with others to prepare for an ever-changing career where adaptability is key.
Things IT Undergrads Should Know (But Don't)
This document provides advice for IT undergrads on things they should know but often don't. It emphasizes that the goal of an IT degree is to learn how to solve human problems using computers. It stresses that the most important language for undergrads to know is SQL. It also notes that employers hire programmers based on their problem-solving skills rather than specific languages. Undergrads should focus on learning fundamentals in college and exploring outside projects as soft skills and adaptability are crucial for success in the real world of constantly changing requirements and impossible deadlines.
From Novice to Expert: A Pragmatic Approach to Learning
From Novice to Expert discusses a pragmatic approach to learning based on the Dreyfus model of skill acquisition. The model describes five stages from novice to expert: novice, advanced beginner, competent, proficient, and expert. As individuals progress through these stages, their decision making shifts from relying solely on rules to developing intuition through experience. The document suggests applying this framework to understand the different needs of developers at various experience levels.
Lambda Expressions in Java 8
The document discusses Java 8 lambda expressions and how they can be used to filter, map, and reduce collections. It provides examples of filtering a list of employees to only those over age 60, mapping a list of employees to a list of their full names, and reducing a list of employees to calculate their total salary. It notes how lambda expressions allow bulk data operations on collections in a similar manner to SQL queries.
Preparing for the WebGeek DevCup
The document provides tips for preparing for a hackathon event called the WebGeek DevCup. It recommends preparing your application framework ahead of time by choosing technologies and setting up modules like authentication, but not completing the full application. It also suggests preparing your development environment, using version control, potentially deploying code, and ensuring good team communication and self-care during the event. The goal is to minimize time spent on setup during the hackathon in order to focus on coding the full application within the limited timeframe.
Productive text editing with Vim
This document provides tips for using the Vim text editor. It begins with an overview of Vim, describing it as an old but common text editor present on many Unix systems. It then provides 9 tips for using Vim, including using insert mode only when needed, using motions beyond just "i" to enter insert mode, using normal mode for faster navigation, learning text manipulation commands, combining commands with motions, using visual mode to select text, splitting screens and tabs, using plugins, and learning something new each day. It concludes by thanking the reader and providing links to the author's GitHub, Twitter, and personal website.
Ruby and Rails by Example (GeekCamp edition)
The document provides examples of how to perform common programming tasks in Ruby and Ruby on Rails compared to other languages like C#. It shows how Ruby and Rails allow doing more with less code through features like hashes, object oriented programming, metaprogramming, and the MVC framework.

What it takes to be a Web Developer
Web developers require a passion for continuous learning across the fields of web design, software engineering, domain knowledge, and infrastructure. To succeed, they must stay up-to-date with new tools and methodologies through online resources and by building their skills in languages like HTML, CSS, JavaScript, PHP, and frameworks like Ruby on Rails.
Ruby and Rails by example
This document provides examples of how to perform common tasks in Ruby and Ruby on Rails using less code compared to other languages like C#. It begins with an overview of Ruby's simplicity and complexity. Several examples are given that show how to create hashes, print output, build binary trees, define classes and modules, call methods, perform calculations, sort and select data, define instance behaviors, and include modules. The document concludes by providing examples of generating a basic Twitter clone app in Rails and scaling it up.
Ruby on Rails
Ruby is a dynamic, open source programming language that is interpreted, object-oriented, and functional. It focuses on simplicity and emphasizes programmer productivity. Ruby on Rails is a web application framework built on Ruby that follows the model-view-controller architectural pattern. It aims to make web development faster and easier through its conventions, including generating scaffolding for basic CRUD operations on models.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
