The document discusses Haxe, an open source programming language that can target multiple platforms like desktop, web, mobile and server side applications. It summarizes Haxe's current version and roadmap, differences from ActionScript 3, package and class structures, basic types, constructors and main functions, generics, typedefs, iterators, function pointers, casting, and how to install and compile Haxe projects. It also lists popular IDEs and online references for Haxe.
Two years ago I inherited jsdom, a project of breathtaking scope. In essence, it aims to simulate a browser in JavaScript, by implementing JavaScript versions of a wide variety of web standards (much more than just the DOM). While maintaining jsdom for the last two years, and eventually bringing it to a 1.0 release, I learned an incredible amount about the web. I want to share with you what I’ve learned: the history of the standards and implementations of them that make up the web; the interaction between seemingly-disparate parts of the platform; and all about the strange APIs we’ve come to know and love. You should walk away from this talk with a new appreciation for how browsers work—and how, through the ongoing effort of a community of contributors and package maintainers, we’ve been able to recreate one in pure JavaScript.
Our favorite language is now powering everything from event-driven servers to robots to Git clients to 3D games. The JavaScript package ecosystem has quickly outpaced past that of most other languages, allowing our vibrant community to showcase their talent. The front-end framework war has been taken to the next level, with heavy-hitters like Ember and Angular ushering in the new generation of long-lived, component-based web apps. The extensible web movement, spearheaded by the newly-reformed W3C Technical Architecture Group, has promised to place JavaScript squarely at the foundation of the web platform. Now, the language improvements of ES6 are slowly but surely making their way into the mainstream— witness the recent interest in using generators for async programming. And all the while, whispers of ES7 features are starting to circulate…
JavaScript has grown up. Now it's time to see how far it can go.
Slides from a presentation that David Lopez (@lopezator) and me made for the students of the University of the Basque Country (UPV/EHU) where we talk about current technologies and methodologies used in professional web development.
CSS3, jQuery, Composer, MVC, Clean Code, Git, etc. are different items we talked about.

JavaScript Everywhere! Creating a 100% JavaScript web stackTom Croucher
One of the costs of working on the web has traditionally been having to work in multiple languages. JavaScript has been the only choice for web front-ends, but as soon as you start back-end work, it can be anything from PHP to Python to Perl to Ruby or even C. Anything, that is, but JavaScript.In the last year server-side JavaScript has leapt forward with a passion, partly due to CommonJS but also due to NodeJS. With these new advances we have an opportunity to enjoy more code re-use, and faster, more efficient pages.
We’ll explore server-side JavaScript and look at how we can use a JavaScript DOM/BOM to run YUI3 on NodeJS, allowing us to reuse the same code on the client and the server, deliver targeted experiences to various classes of client, and smoke test DOM operations during continuous integration.

Automatically Assessing Code Understandability: How Far Are We?sscalabrino
Program understanding plays a pivotal role in software maintenance and evolution: a deep understanding of code
is the stepping stone for most software-related activities, such as bug fixing or testing. Being able to measure the understandability of a piece of code might help in estimating the effort required for a maintenance activity, in comparing the quality of alternative implementations, or even in predicting bugs. Unfortunately, there are no existing metrics specifically designed to assess the understandability of a given code snippet. In this paper, we perform a first step in this direction, by studying the extent to which several types of metrics computed on code, documentation, and developers correlate with code understandability. To perform such an investigation we ran a study with 46 participants who were asked to understand eight code snippets each. We collected a total of 324 evaluations aiming at assessing the perceived understandability, the actual level of understanding, and the time needed to understand a code snippet. Our results demonstrate that none of the (existing and new) metrics we considered is able to capture code understandability, not even the ones assumed to assess quality attributes strongly related with it, such as code readability and complexity.

Clean Code at Silicon Valley Code Camp 2011 (02/17/2012)Theo Jungeblut
Clean Code presentation for the Silicon Valley Code Camp 2011 based on the Clean Code Developer initiative created in Germany by Ralf Westphal & Stefan Lieser. Showing how to improve Code Quality by applying
Best Practices and Design Pattern while utilizing existing tools for better maintainable code.
Over the lifetime of a product, maintaining the product is actually one - if not the most - expensive area(s) of the overall product costs. Writing clean code can significantly lower these costs. However, writing clean code also makes you more efficient during the initial development time and results in more stable code.
At this talk, you will be presented design patterns and best practices which will make you write better and more easily maintainable code. You will learn how to apply them by using an existing implementation as the starting point of the presentation. Finally, patterns & practices benefits are explained. This presentation is based on C# and Visual Studio 2010. However, the demonstrated patterns and practice can be applied to every other programming language too.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
