10 Things I Hate About Scala
I love Scala, I really do. I find Scala both more productive and more fun then any of the many languages I have worked with before. There are many reasons to use to Scala; however, I will not be talking about them.
Instead, in this talk I will cover some of the things I find annoying or disappointing in Scala. For each I will explain the issue, why it is so, whether or not it is likely to ever change, and what, if anything, we can do about it in the mean time.
The issues covered will include:
Limitations on type inference
Type Erasure
Binary incompatibility
Limitations on overloading
Standard library quality
And more
The lecture is geared towards those who have written between 10 and 10 millions lines of Scala code.
Introduction to java
This document provides an introduction to Java. It discusses the history of Java, noting it was developed by James Gosling at Sun Microsystems in 1991. It states that Java resides on many platforms like mobile devices, desktops, servers, embedded devices, and the cloud. The key principle of Java is "write once, run anywhere." It also discusses Java libraries, versions of Java, features of Java like being object-oriented and portable, and how to install and set up Java. It provides an example of a simple "Hello World" Java program. It also covers Java data types, variables, typecasting, arrays, comments, and the Scanner class.
“Insulin” for Scala’s Syntactic Diabetes
See http://www.scalapeno.org.il/#!tzach-zohar/jwhyy:
One of the most common criticisms of Scala, and indeed one of the most concerning ones - is its "Syntactic Diabetes": There's so much "Syntactic Sugar" - so many different ways to code the same thing - that developers might easily get lost. This makes many developers and organizations weary of adopting Scala as a primary language, fearing the training and maintenance costs this problem might entail.
In this talk we'll explain the problem through some real-life examples from Kenshoo's 2- year experience with Scala, and move on to the solutions applied at Kenshoo and elsewhere to resolve this. Among these, we'll discuss style guides, automatic style checkers, Odersky's "Scala Levels", code review tips and more.
If you're a developer thinking about trying Scala out, or a Scala enthusiast trying to convince your teammates or bosses to do so - this talk is for you.

Scala jargon cheatsheet
This document provides a dictionary of scala programming concepts including definitions of common jargon like ADT, typeclasses, extension methods, and call-by semantics. It defines ADT as algebraic data types, which were introduced in languages like Algol 60 and ML, and pattern matching which allows decomposing ADT values. Typeclasses are defined as rules for types like equality, with instances providing implementations. Extension methods and implicit conversions add methods to types via implicit parameters. Call-by-name and call-by-need semantics are discussed in relation to lazy evaluation.
Scala cheatsheet
This document provides a cheat sheet overview of Scala concepts including packages, imports, variables, constants, classes, traits, generics, methods, functions, operators, arrays, main methods, annotations, assignments, selection, iteration and references. Key points are that Scala uses packages similarly to Java but with curly brace delimiters, imports can be used anywhere in a file, variables use 'var', constants use 'val', classes inherit from Any and can use traits for mixins, generics are defined with type parameters, functions are objects, operators are methods, arrays are classes, main returns Unit, and assignments use = while iteration prefers recursion over loops.
Java Intro
The document outlines the topics covered in an advanced Java programming course, including object-oriented programming concepts, Java programming fundamentals, GUI programming, networking, and server-side programming. It also provides examples of Java code demonstrating basic syntax, methods, classes, strings, and math functions.

Context bounds and implicitly make working with type classes cleaner. @ImplicitNotFound provides helpful error messages. Low priority default implicits are suggested for providing type class instances without causing issues for user-defined instances.
Scala fundamentals
This document provides an overview of Scala fundamentals including:
- Scala is a programming language for the JVM that supports both object-oriented and functional paradigms.
- It defines variables, values, lazy values, functions, types, classes, objects, traits, and higher-order functions.
- Classes can extend other classes and traits, allowing for multiple inheritance. Objects are used as singletons.
- Functional concepts like immutability, anonymous functions, and higher-order functions are supported.
Few simple-type-tricks in scala
This document discusses various techniques for working with types in Scala, including:
1. The main alternatives for Scala types including classical OO, algebraic, generic, and structured types. It recommends choosing styles based on use cases and setting guidelines.
2. The differences between run-time and compile-time dispatch and how they are implemented in Scala.
3. Techniques for working with types including tagged types, type aliases, and implicit evidence to provide different behaviors based on types known at compile-time.
4. Resources for learning more about advanced type-level programming in Scala, particularly the Shapeless library.
Types by Adform Research, Saulius Valatka
Scala has a static, strong, and Turing complete type system that can infer types. It supports object-oriented programming with named types like Dog and functional programming with parameterized types like List[Int]. New types can be defined through classes, traits, case classes, and type members. Types are more general than classes and include structural types. Variance controls subtype relationships for parameterized types. Type bounds and existential types provide additional type safety. Higher kinded types allow types to be parameterized over other types.
Unsafe to typesafe
Regis Leray will give a talk about shifting from unsafe to typesafe programming in Scala. He discusses how functions are the fundamental unit of computation and how the Scala compiler helps catch errors through strong typing. Examples are given of unsafe code that can cause errors at runtime versus safer alternatives using options, sealed traits, and case classes that enable the compiler to catch problems early. The talk encourages using the power of functions and typesafety to build more robust programs.
Introduction To Scala
Short introduction to the Scala programming language which I presented on the Ebay/Marktplaats Tech Tuesday
Oops in PHP
The document discusses object oriented concepts in PHP. Some key points:
- PHP 5 introduced a complete object oriented programming model, allowing PHP programmers to code like Java and C#.
- Object oriented programming in PHP revolves around classes, which act as templates to define objects. Classes contain properties (variables) and methods (functions).
- The document provides a step-by-step process for developing an object oriented PHP application, including creating classes, instantiating objects from classes, setting and getting object properties and methods, and restricting access using modifiers.
Scala - the good, the bad and the very ugly
The document discusses the pros and cons of the Scala programming language. It outlines some of the good aspects of Scala like its functional and object-oriented nature, immutable collections, and ability to reuse Java libraries. However, it also notes challenges like slow compiler and IDE tools, a steep learning curve, and the potential for overly complex code. While Scala has drawbacks, the author believes it could be suitable for small side modules but not general new projects due to its deficiencies, and that guidelines are needed to prevent misuse of its expressive capabilities.
Scala’s implicits
A gentle introduction on the use of implicit values & conversions in Scala.
It also introduces some design patterns for which implicit(s) are the building blocks.

Advanced Reflection in Pharo
This document discusses advanced reflection capabilities in Pharo. It describes how instance variables are currently represented as strings but could be modeled as objects using layouts and slots. It also explains how method structures are not currently modeled at a fine-grained level and proposes using abstract syntax trees (ASTs) to represent methods as objects with sub-elements like message sends, assignments, and variable access. This would enable capabilities like behavioral reflection through meta-object links on AST nodes. The document advocates "ASTs everywhere" and sub-method reflection with meta-links in future versions of Pharo.
FFW Gabrovo PMG - PHP OOP Part 3
This document provides an overview of object-oriented programming concepts in PHP including static methods and properties, constants, abstraction and interfaces, overloading, object iteration, cloning, serialization, namespaces, and autoloading classes. Key points covered include how to define static class members, constants, abstract classes and interfaces, magic methods for overloading, implementing interfaces for object iteration, cloning objects and the clone constructor, serializing and unserializing objects, using namespaces to organize code, and defining an autoload function to include class files automatically.
PHP Classes and OOPS Concept
PHP Classes and OOPS ConceptDot Com Infoway - Custom Software, Mobile, Web Application Development and Digital Marketing Company
This document provides an introduction to object-oriented programming concepts in PHP including defining classes, creating objects, using methods and properties, inheritance, and the differences between OOP in PHP4 and PHP5. Classes define objects with attributes and behaviors, objects are instantiated from classes and can access methods and properties, and child classes inherit attributes and behaviors from parent classes.Swift in SwiftUI
The document discusses several Swift Evolution proposals including:
- Implicit returns from single-expression functions and closures which allows omitting the return keyword from functions/closures with a single expression.
- Opaque result types which allow abstracting away types using some to preserve type identity and information hiding.
- The Identifiable protocol which provides a standard way to identify values based on an ID property to enable change tracking in SwiftUI lists and other APIs.
- Property wrappers which define custom attributes to encapsulate property storage and behavior, eliminating boilerplate and providing patterns to define properties like @State, @Binding, @Published etc.
