Javascript in Linux Desktop
The document discusses using JavaScript in Linux desktop applications. It describes how JavaScript can be used for layout, styling, and programming of desktop apps through platforms like Mozilla's XULRunner and GNOME's Seed/GJS. These platforms provide JavaScript runtimes and bindings that allow access to native desktop libraries from JavaScript code.
Quick Review of Desktop and Native Apps using Javascript
This document reviews several options for building desktop applications with JavaScript, including GLUEScript, Seed, GJS, Qt Script, QtQuick, and TopCube. It finds that the GTK-based options like Seed and GJS have issues, while Qt-based approaches need more investigation. It also discusses using Node.js with TopCube or HTML5 for desktop GUIs, and native platforms like Java and Objective-C for phone apps. The document concludes that further options should be explored but typical bindings for C++ and Python may be better for desktop for now.

Introducing Yeoman 1.0 beta
This document introduces a front-end workflow consisting of three tools: yo, bower, and grunt. Yo is used to set up a project structure and folders. Bower manages front-end library dependencies. Grunt is a task runner that can compile Sass/Less to CSS, run tests, and minify files for production. The workflow allows setting up a new project, adding libraries, running tests, and deploying minified code with one command.
Happy hacking with Plone
We, Plone developers invest time in Plone to build something nice and attractive that users love. There is a need for a hacking tool that allows non-technical users to easily change and customize Plone sites through a modern web interface, rather than relying on hackable systems. Rapido is proposed as a solution, which would allow creating custom content chunks and scripts using basic HTML and Python knowledge, and injecting them into Plone through Diazo theming. Rapido scripts would have access to Plone APIs and content in a secure manner, and it includes a REST API and Plone content rules integration out of the box.
Devenez le plus heureux des Front-end avec Gulp.js
This document discusses using Gulp as a task runner for front-end development. It introduces Gulp and compares it to Grunt, explaining that Gulp uses streaming for faster performance. The document then demonstrates how to set up a basic Gulpfile to compile Sass files to CSS. It covers the main Gulp functions like gulp.task(), gulp.src(), gulp.dest(), and gulp.watch(), and shows how to create dependent tasks. Finally, it recommends some common Gulp plugins for tasks like autoprefixing, uncss, concatenation, minification, and more.

Understanding how concurrency work in os
This document discusses concurrency in operating systems and different programming languages. It explains how concurrency works at the OS level using schedulers and threads/processes. It then compares implementations of concurrency in Python, Java, and Go. Python uses threads but is constrained by the GIL, Java uses native threads, and Go uses lightweight goroutines scheduled across OS threads. The document cautions that while goroutines make concurrency easy, there are still costs to consider. It concludes by noting languages evolve over time and no approach is inherently unable to handle high concurrency applications.

Geb+spock: let your functional tests live long and prosper
Functional testing, as any other testing, is important to ensure the health of our apps. However, functional tests are often tricky, too susceptible to change, and their maintenance ends up being a nightmare. Are we hopeless then? Not at all! Luckily, there are tools to ease this task like Geb and Spock, which help us to create well structured, comprehensive, and easy to maintain tests. In this talk we will review these tools, showing different options for creating the tests.

Planbox Backbone MVC
Migrating MVC to the Front-end using Backbone JS.
Planbox is a single-page web application for Agile project management. It was built using the traditional MVC stack with CodeIgniter (PHP) and jQuery (Javascript). AJAX was heavily used to update DOM elements to offer a dynamic user experience. UX logic code quickly became spread across Javascript and PHP. The application code base quickly became unmanageable and scaling functionality became difficult. Things had to change.
A decision was made to change architecture: bring all the UX logic in the front-end, and turn the back-end into an engine in charge of business logic.
This talk is about this experience. How we moved the MVC stack from the back-end to the front-end. How we used Backbone JS as the foundation of our front-end framework and built on top. How the backend became a black-box with a Restful API. What lessons we learned, what benefits we gained, and what reflections we made about the future of MVC in Javascript.

An introduction to React.js
This document provides an introduction to React.js, including:
- React.js uses a virtual DOM for improved performance over directly manipulating the real DOM. Components are used to build up the UI and can contain state that updates the view on change.
- The Flux architecture is described using React with unidirectional data flow from Actions to Stores to Views via a Dispatcher. This ensures state changes in a predictable way.
- Setting up React with tools like Browserify/Webpack for module bundling is discussed, along with additional topics like PropTypes, mixins, server-side rendering and React Native.

React JS and why it's awesome
This document provides an overview of React, including initial reactions to it, fundamental concepts like components and one-way data flow, and how the virtual DOM works. Some key points covered include:
- Initial reactions to React were mixed, with some finding it "ugly" but others seeing benefits like separation of concerns with components.
- Everything in React is a component, with data flowing in one direction from parent to child via props. State is mutable within a component.
- By using a virtual DOM, React can efficiently update the real DOM by only making necessary changes, keeping the interface fast and pure.

Javascript, the GNOME way (JSConf EU 2011)
Javascript can be used to develop applications and interfaces for the GNOME desktop environment. GNOME 3 introduced the GNOME Shell, which uses Javascript and the GObject Introspection system to interface GNOME libraries. GObject Introspection extracts metadata from C libraries to make them accessible from Javascript via bindings. This allows Javascript programs to import and use functionality from GNOME libraries. There are two engines for running GNOME Javascript code: GJS, which uses Mozilla's Spidermonkey, and Seed, which uses Apple's JavascriptCore.

This presentation introduces Go to system programmers and cover some of the novel/useful features of the language.
A First Look at Google's Go Programming Language
Go is a new systems programming language from Google. Go has many interesting features such as 'communication channels' that makes it suitable for use in multi-core machines, and network programming. With Ken Thompson (of Unix fame) as one of its designers, Go has elegant and minimal design that is appealing to most programmers. This talk gives a technical introduction to Go that is of interest to anyone working in system software.
[Presentation I have in 2010 - I haven't updated it with recent changes to the Go language]
Golang introduction
Go is a programming language created at Google to address issues with slowness, clumsiness, and lack of scalability in other languages like C++ used at Google. Key goals in developing Go were to eliminate slowness in development, improve effectiveness, and maintain or improve scale. Go provides features like built-in concurrency and goroutines to help solve problems at Google involving large, distributed systems.
Opensource Software usability
This document discusses improving the usability of open source software. It explores options for developing graphical user interfaces for open source projects. Developers can work on existing open source projects or start new ones focused on areas like operating systems, applications, frontends, configuration files, or translations. Popular graphical libraries like GTK+ and Qt can be used to develop GUIs, and bindings exist for languages like Python, Perl, and C++. Tools like Glade and Qt Designer allow visual design of user interfaces. Frameworks like wxWidgets aim to create truly cross-platform applications with native looks and feels. The document provides examples of "Hello World" programs using different libraries and languages.
G T K+ 101
GTK+ is a highly usable and feature-rich toolkit for building graphical user interfaces that is written in C but has bindings to many other languages. It provides stability, cross-platform compatibility, and an accommodating interface. GTK+ is part of the GNU project and relies on supporting libraries like GLib, GObject, GDK, Pango, and ATK. Applications using GTK+ follow a standard structure, initializing the environment, running the main event loop, using data types like widgets, and defining callback functions to handle events.

Golang : A Hype or the Future?
Created by Robert Griesemer, Rob Pike and Ken Thompson for Google, GoLang was reportedly built by developers when they were waiting for the code compilation to complete in a project. The three main capabilities they certainly sought-after were the ease of coding, efficient code-compilation and efficient execution. Bringing all these capabilities in one language is what made Go so special.
Fundamentals of Golang
Go or Golang is a programming language created by Google in 2009 that uses syntax similar to C. It features simplicity, built-in concurrency mechanisms, object-oriented programming, and a fast compiler. A typical Go program has three main sections - packages, imports, and functions. Packages contain reusable code, imports bring packages into the current file, and functions define reusable blocks of code. Variables can be declared, functions defined and called, and input/output handled to write complete Go programs.
Android is going to Go! - Android and goland - Almog Baku
This document discusses using the Go programming language for Android development. It begins with an introduction to Go, showing basic "Hello World" examples. It then demonstrates how to use goroutines for concurrency, channels for communication between goroutines, and Go's standard library features. The document introduces Go Mobile, a tool for building native Android and iOS apps and libraries entirely in Go. It provides examples of creating native Go apps and Go libraries that interface with Java/Swift through bindings. In the end, it discusses some disadvantages of the Go mobile approach.
Android is going to Go! Android and Golang
I recently talked in Droidcon about building using Go with Android
We talked about what is Go? And why it's so awesome? And how can we use it with Android?
On this session we've learnt a little bit about Go, and how can we use it with Android- about the use cases, and the secret
tricks to use it with mobile applications.

Dependency management in golang
Having trouble managing dependencies with golang ? Here's how to resolve those issues using some of the best tools built by the community for the community.
PhoneGap
PhoneGap is a free and open source framework that allows developers to build mobile apps using standard web technologies like HTML, CSS, and JavaScript. It works by wrapping native device APIs with JavaScript interfaces so that apps can access features like cameras and device sensors. PhoneGap apps are hybrid - they are essentially web apps that are wrapped inside a native container and deployed to mobile platforms. The document provides an overview of PhoneGap and instructions for setting up a basic PhoneGap Android project in Eclipse. It also discusses plugins, tools, and how to create custom plugins.
Introduction to go lang

Go programing language
Go is a programming language created by Google engineers to be concise, compile quickly, and support concurrency. It shares similarities with C in syntax and compiled output but includes automatic memory management and built-in support for concurrency. A basic Go program consists of packages, imported packages, functions, variables, and statements. The document then provides examples of a simple Go program that prints "Hello" and explains how to save, compile, and run it. It also discusses Go's performance advantages over other languages and how it is compiled to efficient machine code like C.
