Flow control in Python
Flow control statements determine program execution based on conditions. Boolean values in conditions are either True or False as determined by comparison operators. Common flow control statements include if/else/elif to check conditions and while/for loops to repeat actions, and functions from imported modules like random and sys can be used to generate random numbers and exit programs.
Java Chapter 05 - Conditions & Loops: part 2
This document discusses conditionals and loops in Java programming. It covers boolean expressions that evaluate to true or false, which are used in conditional statements like if and while statements to control program flow. Logical operators like && and || can be used to build complex conditions. If statements allow executing code conditionally, while loops repeat code execution. Collections like ArrayList are also introduced to store and iterate over multiple values. In summary, conditionals and loops allow controlling program flow, boolean expressions are used in conditions, and logical operators help build complex conditional logic.
Java Chapter 05 - Conditions & Loops: part 1
The document is a chapter about conditionals and loops in Java. It discusses boolean expressions, if and if-else statements for making decisions, comparing data, while loops, iterators, and the ArrayList class. It focuses on programming statements that allow programs to make decisions and repeat processing steps in loops to control the flow of execution through a method. Key concepts covered include using logical operators to construct conditions, proper indentation, how if-else statements and nested if statements work, comparing strings, avoiding infinite loops, using iterators to process groups of items, and how ArrayList objects store and access lists of objects.
Java Chapter 05 - Conditions & Loops: part 6
Iterators are objects that allow sequential access to elements in a collection. An iterator has methods like hasNext() to check if there are more elements, and next() to access the next element. Several Java classes like Scanner and ArrayList are iterators. The example code shows how a Scanner can act as an iterator to read lines from a file and parse URLs on each line into path components.
Swift, a quick overview
This document provides an overview of Swift, including some key features such as no header files, type inference, computed properties, property observers, generics, extensions, closures, optionals, and interoperability with Objective-C. It notes that Swift aims to be a safe language with features like array typing, optional values to mark nil, and requirements to handle all cases in switches. The document concludes by stating Swift code can be accessed from Objective-C with the @objc prefix and that Swift classes can inherit from Objective-C classes.

Introduction to Functional Programming
Functional programming is a programming paradigm that emphasizes functions and immutable data. The key principles of functional programming include:
1) Functional purity by avoiding side effects and making functions dependent only on their inputs.
2) Favoring expressions over statements by writing small, pure functions that take inputs and return outputs.
3) Treating functions as first-class objects that can be passed into other functions as arguments and returned from functions.
Haskell @ HAN Arnhem 2013-2014
This document provides an introduction and overview of the Haskell programming language. It discusses:
- The speaker's background and an introduction to Simon Peyton Jones, a researcher at Microsoft.
- An overview of what Haskell is - a purely functional, lazy, higher-order, strongly typed general purpose language.
- Why learning Haskell is useful even if you don't use it primarily - it encourages different thinking that can improve programming in any language.
- A brief history of the development of Haskell and how it has evolved over time through various versions.
- Examples of real-world applications of Haskell like text tools, GUI programming, databases, networking, and the tiling window manager xmonad

Swift aims to be more modern, safer, and easier to use than Objective-C. Key features include not needing semicolons, optionals for null checking, tuples, and strong typing. Swift also focuses on optimizations to be faster than C and provides memory management without needing to use retain/release like in Objective-C.
5 things you need to know about the Scala compiler
How much do you really know about how the Scala compiler works? This talk gives a high-level intro to a few things that can help you understand why Scala compilation is slow sometimes.
Concurrent Applications with F# Agents
This document discusses F# agents and the actor model of concurrency. It begins with definitions of concurrent and parallel programming. F# agents implement Erlang-style message passing using the actor model, where independent actors receive and process messages asynchronously. However, F# agents differ from Erlang in that they are contained within a single process and lack features like supervisors and durable mailboxes. The presentation includes demos of F# agents and additional resources for learning more about concurrency in F#.

Xtend - better java with -less- noise
This document discusses features of the Xtend programming language that make Java code cleaner and more concise, including active annotations, extension methods, lambda expressions, switch expressions, and more. It provides code examples to demonstrate how Xtend allows generating boilerplate code through active annotations, adding methods to existing types via extension methods, using lambda expressions and the with operator for cleaner code, and more powerful switch expressions. The document recommends resources for learning more about Xtend, including documentation, presentations, blogs, and example source code.
Bank OCR Coding Dojo
This document describes a Coding Dojo, which is a safe place outside of work to practice software development skills through deliberate practice of techniques like test-driven development (TDD) and pair programming. It provides an example assignment to practice an outside-in TDD approach for a bank optical character recognition (OCR) problem that involves parsing account numbers from scanned documents. Participants are instructed to work through the outer application programming interface initially by either ignoring a failing guiding test or stubbing dependencies to make it pass initially before implementing the full solution.
The IoT testing atlas
The document describes The IoT Testing Atlas, which is a method to systematically test all possible states of an Internet of Things (IoT) system. It does this by mapping out all potential states of each component in a circle diagram called an atlas. It then generates test cases by rotating the state of one component at a time while holding the others constant. This allows testing all combinations of states in a visual and comprehensive manner. The atlas approach scales well to complex IoT systems and provides a common framework to coordinate testing across teams.
Lambdas
This document discusses Java 8 features including defining methods in interfaces, functional programming concepts, lambda expressions, and the stream API. Key points include: interfaces can now define default and static methods; functional programming uses declarative code, avoids mutability, and handles concurrency; lambda expressions define anonymous methods; and the stream API processes data in parallel streams to leverage multi-core architectures.

It also includes screenshots and code snippets from demos and tests of a basic calculator using the library to parse arguments, read and write arguments to XML, and measure code coverage.
RubyConf Taiwan 2016 - Large scale Rails applications
This document discusses strategies for scaling large Rails applications. It advocates separating applications into thin controllers, fat models, and following principles like single responsibility and stateless objects. The document also recommends separating applications into layers like services, forms, policies, queries, adapters, and models. Services describe processes, forms convert inputs, policies describe permissions, queries access data, adapters translate between languages, and models manage data. It argues this architecture makes applications more flexible, testable, and debuggable while allowing for easier migration between providers.
RoelTyper
RoelTyper is a tool that uses heuristics to quickly reconstruct types for Smalltalk instance variables by analyzing bytecode. It examines messages sent to and assignments of instance variables to infer their possible types. The tool has been implemented for both VisualWorks and Squeak, with some minor class differences between the environments. RoelTyper provides type information to development tools and can help catch type errors.
Functions, anonymous functions and the function type
This document outlines functions in Kotlin including what a function is, calling a function, the anatomy of a function, named vs anonymous functions, function types, implicit returns, the it keyword, type inference, higher-order functions, lambda functions, function inlining, closures, and how functions are supported differently in Kotlin and Java. It also provides questions and answers on topics like backtick symbol naming, top-level functions, default arguments, named arguments, Nothing type, and the TODO() function in Kotlin.

Google App Engine - exploiting limitations
Google App Engine is a PaaS that allows developers to build and host web applications on Google's infrastructure. It provides automatic scaling and simulates a production environment through its SDK. However, applications must comply with App Engine's rules, including a read-only filesystem, 30 second response times, and no socket connections or processes. Data is stored in Google's distributed Datastore, which uses entities instead of tables and does not support joins, aggregation, or transactions across entity groups. To work within these limitations, developers must change their approach to focus on the Datastore's strengths like simplicity and denormalize their data models.

The document discusses why software testing is important. It notes that software today controls many safety critical systems and embedded devices. Software failures can have catastrophic consequences, costing lives and billions of dollars in losses. Testing aims to find faults early in the development process and prevent failures by verifying software meets requirements. The costs of inadequate testing are high, so testing is necessary to improve quality, reduce costs from bugs, and ensure customer satisfaction.
Software Requirements engineering
The document discusses key concepts in software requirements engineering including requirements, requirements engineering activities, and types of requirements. It defines a requirement as a statement that captures stakeholder needs and must be met for a system to solve a problem. Requirements engineering involves eliciting, analyzing, specifying, and managing requirements throughout the system development lifecycle. There are functional requirements that define what a system should do and non-functional requirements relating to qualities like performance, security, and usability. The document outlines common requirements engineering processes such as elicitation, analysis, specification, and management.
Software architectural patterns
This document discusses several software architecture styles including layered architecture, client-server, master-slave, pipe-filter, broker, peer-to-peer, event-bus, model-view-controller, blackboard, and interpreter. Each architecture style is briefly described and examples are provided for common uses of each style.
Class based modeling
The document discusses class identification for a system. It identifies potential classes like homeowner, sensor, control panel, system, and sensor event by examining nouns in use cases. It then evaluates the potential classes against characteristics like retained information, needed services, and common attributes to determine which should be defined as classes in a requirements model. The security system, sensor, control panel, and sensor event classes are selected as they meet the evaluated characteristics.
Class diagram
Class diagrams are used to show the different objects in a system, their attributes, operations, and the relationships among them. They are the main building block in object-oriented modeling and are used to visualize and design the structure and interactions of application objects. Class diagrams help design and develop object-oriented systems by modeling real-world concepts as classes.
State diagram
Use cases are best suited for reactive and interactive systems, but have some shortcomings. They do not adequately capture activities for systems that are algorithm-driven or data-intensive, and may leave out important parts of the environment. State diagrams show the behavior of a system in response to external stimuli by illustrating the actual state changes, rather than the processes that created them. They identify states, transitions between states triggered by events, and can have an initial and terminating state.
Use case Modeling
Use case modeling involves describing how users will interact with a system to achieve goals. A use case represents a dialog between a user and the system, specifying what information must pass between them without detailing the system's internal workings. Each use case should have a name that includes a verb describing the user's goal. Actors represent people or systems that interact with the system-to-be to accomplish responsibilities. Sequence diagrams visually depict the information exchanged between actors and the system in specific use case scenarios.
User stories
a) The user can run the system on Windows XP and Linux.
This is specifying an implementation detail rather than a user goal or need. Good user stories focus on what the user needs, not how it will be implemented.
b) All graphing and charting will be done using a third-party library.
This specifies an implementation detail rather than a user goal or need. Good user stories focus on what the user needs, not how it will be implemented.
g) The system will use Log4J to log all error messages to a file.
This specifies an implementation detail rather than a user goal or need. Good user stories focus on what the user needs, not how it will be implemented
Dev ops
This document discusses DevOps, which aims to bridge the gap between development and operations teams. It involves merging these teams so engineers work across the entire application lifecycle. Key DevOps practices include adopting Agile project management, shifting testing left through continuous integration and delivery, using tools to automate processes, and monitoring applications. DevOps can improve speed, reliability, collaboration and security. Implementing DevOps requires cultural change and using the right tools and practices.
Agile Methodology
This document discusses agile analysis and modeling processes and methodologies. It describes the core principles of the Agile Manifesto which emphasize individuals, working software, customer collaboration, and responding to change. It then outlines the agile analysis process of identifying users and goals, defining usage patterns and solutions. It also discusses the core principles and practices of extreme programming and scrum, including events, roles, and artifacts. It notes some limitations of agile methodologies in terms of dependence on user involvement and small team sizes.
Software Process Model
This document discusses different software process models including waterfall, prototyping, incremental development, spiral, RAD, and V-models. It explains the key stages and benefits and limitations of each model. The document emphasizes that each model tries to provide a framework for software development but that borrowing from multiple models may be necessary. Real-life examples like Windows development are given to illustrate using the spiral model.
Introduction to Software Engineering Course
This document provides an overview and introduction to the CSE 2205 Software Engineering course. It discusses the educational objectives of learning that building large software systems requires more than just programming. It introduces the instructor and describes how the course will be taught based on real-world experience rather than just textbooks. It also outlines the major course components, including a large multi-person project with milestones, lectures, presentations, and exams. Finally, it briefly defines software engineering and discusses why studying it is important given the size and critical nature of software today.
C files
Files are containers used for storing data in computer storage devices. They allow data to be preserved even after a program terminates, and make it easy to enter large amounts of data and transfer data between computers. There are two main types of files: text files which contain plain text and have a .txt extension, and binary files which store data in 0s and 1s and have other extensions like .bin. Common file operations include creating, opening, closing, and reading from or writing to files using functions like fopen(), fclose(), fprint(), and fscanf() in C.
C pointers
Pointer in C is a variable that stores the address of another variable. The document discusses pointers in C including syntax, accessing pointers, and common mistakes made when working with pointers. It shows how to declare a pointer variable, take the address of a variable and store it in a pointer, dereference a pointer to access the value at the address, and how the value is changed when accessed through a pointer or variable.
C structures
Structures in C allow programmers to define user-defined data types that combine different data types together. A structure is defined using the struct keyword followed by structure name and members. Structure variables are then declared, which allocate memory for multiple variables of different types under one name. An example demonstrates defining a Student structure with members like name, age, branch, and gender, then creating structure variables to store student records.
How to Create Python scripts
This document discusses how to create and run Python scripts on Windows. It explains that Python scripts are files containing Python commands that can be executed like programs. It also notes that Python scripts require a shebang line to specify the Python interpreter when running from the command line. Additionally, it provides steps for creating a batch file to conveniently run Python scripts, including saving the Python file with a .py extension and using a template to create the batch file.
Regular expressions using Python
This document discusses regular expressions (regexes). It explains that regexes allow you to search for text patterns in strings by using special characters to represent repetition, optional elements, character classes and more. The document provides examples of regex patterns to match phone numbers and discusses regex methods like search(), compile(), findall() and sub(). It also covers options for case-insensitive matching and managing complex regexes. In the end it proposes projects for using regexes to extract phone numbers and emails from text as well as detect strong passwords.
Password locker project
This document outlines the steps to create a password locker program: 1) Design the program to take a command line argument for an account name and retrieve the associated password from a dictionary to copy to the clipboard. 2) Handle the command line argument to get the specified account name. 3) Copy the correct password for the given account name from the dictionary to the clipboard. It also mentions installing third-party modules and creating a batch file to run the program.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
