Roles are an excellent object-oriented tool both for allomorphism and for
reuse.
Roles facilitate allomorphism by favoring "does this object do X" versus "is
this object a subclass of X". You often care more about capability than
inheritance. In a sense, roles encode types better than inheritance.
Roles also provide an excellent faculty for reuse. This effectively eliminates
multiple inheritance, which is often the only solution for sharing code between
unrelated classes.
Roles can combine with conflict detection. This eliminates accidental shadowing
of methods that is painful with multiple inheritance and mixins.
Parameterized roles (via MooseX::Role::Parameterized) improve the reusability
of roles by letting each consumer cater the role to its needs. This does
sacrifice some allomorphism, but there are ways to restore it.

Why TypeScript?
with Jeff Francis
OVERVIEW
TypeScript is a type-checked superset of JavaScript that benefits medium-sized to complex JavaScript projects. Why would you want to learn a new language, instead of another JavaScript framework? You have all this existing JavaScript code, so how can you adopt something new without throwing the old stuff out?
This session is about the benefits of using TypeScript on top of JavaScript in your projects, and demonstrate step by step ways of migrating an existing JavaScript project to TypeScript. We will dive into code generated by the compiler and look at resources and tools that make working in TypeScript a pleasurable experience.
OBJECTIVE
To understand when it’s a good idea to use TypeScript.
TARGET AUDIENCE
JavaScript developers.
ASSUMED AUDIENCE KNOWLEDGE
Intermediate JavaScript experience.
FIVE THINGS AUDIENCE MEMBERS WILL LEARN
The basics of TypeScript – types, classes, modules, and functions
How TypeScript’s design makes getting started simple and helps projects
What compiled TypeScript looks like and how to debug
What tools can help take advantage of TypeScript’s type information
How to migrate a JavaScript project to TypeScript
Create your own PHP extension, step by step - phpDay 2012 VeronaPatrick Allaert
Ever been interested by contributing to the PHP core team?
In this workshop you will not only learn how (easy it is) to create your own PHP extension from scratch but you will also strengthen your knowledge of PHP by disecting its internals.
After this workshop, you will be able to create an extension on your own, whether it is to optimize the most CPU intensive parts of your code, to create new bindings to C libraries or just to leverage your PHP knowledge.
And what if PHP was a web framework for the C developer?
This workshop requires a bit of C knowledge and preferably a *nix system.
Presented at Codemotion 2016. Discusses the beginner-level dynamics of the performance-improved PHP 7. Gain expanded knowledge of the spaceship and null coalescing operators, anonymous classes, the new error exception, and the security features of PHP 7.
I demonstrate a small slice of Rakudo, an implementation of a dynamic language with some advanced features.
During the actual talk I used the REPL to do live demonstrations, often taking suggestions from the audience.
Learn Ruby 2011 - Session 5 - Looking for a RescueJames Thompson
In this final language-focussed session we covered the three kinds of blocks used in Ruby: blocks, Procs and lambdas. We also covered error/exception handling in Ruby and reviewed iteration mechanisms.
These are slides from a lecture on Red Flags in Programming that took place at an Israeli Open Source Developers meeting.
Red flags in programming are signs that you likely made a mistake with your application design or code.
Noticing and avoiding these mistakes help us write better code, at any language.
The subject related to mostly dynamic (higher level) languages, even though the sample code is in Perl.

Embracing Clojure: a journey into Clojure adoptionLuca Grulla
What happens when a small team of very experienced developers with no real functional programming experience decides to use Clojure to run a core system architecture component?
This is the story of a 2 years journey of my team with Clojure, sharing learnings, epiphanies, success as well as some of the challenges we encountered.
Clojure is a new dialect of LISP that runs on the Java Virtual Machine (JVM). As a functional language, it offers great benefits in terms of programmer productivity; as a language that runs on the JVM, it also offers the opportunity to reuse existing Java libraries. Simon’s interest is in using Clojure to build desktop applications with the Java Swing GUI library. In this presentation Simon discusses how the power of Clojure can be applied to Swing, and whether it hits the sweet spot.
These are the outline slides that I used for the Pune Clojure Course.
The slides may not be much useful standalone, but I have uploaded them for reference.
This slide aims to describe the basic introduction about Java with the Eclipse platform. Many examples were applied in order to understand the main features of programing by using Java.

Scaladroids: Developing Android Apps with ScalaOstap Andrusiv
Android is a fast-growing mobile operating system with millions of users worldwide.
Scala is a modern programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Why not combine both of them?
There is an increasing interest in functional programming from Java developers and the organisations in which they work. For many companies the challenge now is how to make use of the competitive advantage of functional programming. For developers, how do you adapt your mindset to this newly reimagined paradigm? Through the use of examples and a modular approach to design, Clojure made simple will show how developers can be productive quickly without a major change to their current development life-cycle. We will also cover the Clojure build process, tools and exciting projects out there.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources.

5. Problems with Java as a language
lack of functional programming (FP) support
More FP! (OOP and static typing are not necessary)
verbose syntax
More simplicity!
lack of exibility/extensibility
More freedom!
6. JVM language comparison
from my own point of view
factor Java Groovy Scala Kotlin Clojure
FP support × △ ◯ △ ◯
simplicity × ◯ △ ◯ ◎
exibility × ◯ ◯ ◯ ◎
7. Using Clojure,
we can say goodbye to Java as a language!!
Adieu, Java !
Now we have to say farewell to you, Java (;_;)/~~~
9. Origin of the name Clojure
Clojure is pronounced exactly like closure, where
the s/j has the zh sound as in azure, pleasure etc.
The name was chosen to be unique. I wanted to
involve c (c#), l (lisp) and j (java).
Once I came up with Clojure, given the pun on
closure, the available domains and vast emptiness
of the googlespace, it was an easy decision.
― Rich Hickey, creator of Clojure
cf. meaning and pronunciation of Clojure
10. Clojure /ˈkloʊʒɚ/
* NOT /ˈkloʊd͡ʒɚ/
element meaning
/ˈkloʊʒɚ/ closure, functional programming
C C#(.NET) as a platform, .NET language
l Lisp dialect
j Java as a platform, JVM language
11. 1. Clojure as a FP language
2. Clojure as a Lisp dialect
3. Clojure as a JVM language
19. S-expressions
(f a b c ...)
f: function, macro, special form
a, b, c, ...: arguments
cf. Java
f(a, b, c, ...)
20. Even a function/method de nition
// Java
public void greet(String name) {
System.out.println("Bonjour, " + name + " !");
}
is an S-expression.
;; Clojure
(defn greet [name]
(println (str "Bonjour, " name " !")))
21. Even namespace/package declaration and imports
// Java
package demo_app;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
are S-expressions.
;; Clojure
(ns demo-app.core
(:import (java.io IOException)
(java.util ArrayList List)))
25. BTW,
defn used for function de nition
user=> (macroexpand
#_=> '(defn greet [name]
#_=> (println (str "Bonjour, " name " !"))))
(def greet (clojure.core/fn ([name] (println (str "Bonjour, " name " !")))))
is a macro composed of def, fn special forms.
26. Hard to handle a lot of parentheses?
