Shift Remote: JS - Javascript Build Tools: Past & Beyond - Shedrack Akintayo
In this talk, I'd go through the Evolution of JavaScript build tools, their features of most javascript build tools and what we should be expecting in the future from build tools.
ITT Flisol 2013
This document summarizes an approach to modern web development that separates applications into logical components with single responsibilities. It advocates for building APIs with frameworks like Grails to handle data exchange, separate admin interfaces, and static single page applications using front-end frameworks. Key points include using test-driven development, continuous integration, and pre-generating static content to improve performance and reduce server loads.
QuizUp Web Monorepo
The company had multiple JavaScript projects that each had their own repository, causing issues like duplicate setup work, difficult code sharing between projects, and dependencies not being consistently updated. They created a mono-repository to hold all projects, using the Pants build tool and Node.js scripts to manage dependencies and selective deployment from a single codebase, reducing maintenance overhead and improving collaboration across projects. This approach simplified their workflow and allowed code to be more easily shared while keeping dependencies up to date across all services.
Front-End Tools and Workflows
The document discusses various tools for web development including text editors like Sublime Text and Atom, package managers like NPM and Bower, frontend frameworks like Angular and React, and asset preparation tools like Grunt and Gulp. It provides brief descriptions of the purpose and usage of each.
Blazor - The New Silverlight?
WebAssembly is a new Web Standard for portable code that runs in the browser. Blazor is a Microsoft Project where you can write C# and ASP.NET Core Razor code – making use of WebAssembly. In this session you are invited to start the journey to a new world, a world that can change programming for the Web in the years to come.
ASP.NET Core - Phillosophies, Processes and Tooling
Microsoft has built a rich ecosystem around the various flavors of ASP.NET – MVC, Web API and even WebForms have a place in the modern web development world. So what the heck is up with ASP.NET Core anyways? Microsoft has flipped the ASP.NET world on its head with this fast, cross-platform web framework, designed from the ground up with developers from all walks of life in mind – and the change isn’t as scary as you think.
In this session, we’ll learn about ASP.NET Core and its design philosophies. We’ll learn how to leverage several popular development tools frequently used by developers outside of the ASP.NET ecosystem, including Gulp, Bower, Node and NPM, to build and run our application. Finally, we’ll use Visual Studio Code to create and run our very first ASP.NET Core project (on a Mac no less!)
For current ASP.NET developers, we’ll also touch on the portability of your current ASP.NET code.
Microfrontends Monoreops & Trunkbased based
Slides from my talk at the Coimbatore frontend Meetup on how Microfrontends MonoRepos and Trunk based Development go hand in hand with each other
Short-Training asp.net vNext
The document discusses features and changes in ASP.NET vNext, the future version of ASP.NET. It describes how vNext uses project.json for dependencies instead of references, allows editing code without recompiling, and merges MVC, Web API and Web Pages into a single framework. It also discusses tools for building, running and deploying vNext applications in Visual Studio 2015 and how the runtime will be more modular and cross-platform compared to previous versions of ASP.NET.

Why use Go for web development?
This document discusses the suitability of Go for web development. It notes that while Go's built-in HTML template engine is basic, the Gorazor template engine provides a more powerful way to mix Go code into HTML templates. Code generation approaches also allow Go to behave more dynamically at runtime. Go's fast compilation and use of interfaces make it well-suited for dynamic web applications and large websites. The document concludes that while other languages may be more mature, Go is suitable for developing large, stable, scalable websites that need to be maintained over time.
JEE Conf 2015: Less JS!

It provides an overview of web components goals and standards, introduces Polymer and how it builds on web components, discusses JSF and the PrimeFaces component library, and demos how to use Polymer and PrimeFaces. The goals of web components, Polymer, and PrimeFaces are to reduce code, improve readability and reusability through composable elements. Browser support for the various web component specifications is outlined.
Continous Delivery with CQ
Continuous Delivery is the philosophy of creating software that is in a production-ready state and can be easily deployed to a production system.
How can this be achieved with a CQ website? The first step is to implement Continuous Integration as a foundation of Continuous Delivery.
Continuous Integration forces the team to continually integrate their pieces of software. If we are able to integrate all CQ components with an automated testing process, we can start to implement Continuous Delivery. This also requires that we are able to start and stop CQ automatically by script so that we can execute such automated tests. Other parts of Continuous Delivery are automated deployment to test servers and automated delivery to the customer.
This presentation gives a brief overview of Continuous Delivery and how it can be achieved with CQ. We show an example implementation of this philosophy and which tools have been successfully used in the process.
Web Assembly Big Picture
Web Assembly is a new web standard that defines a binary format for executable code in web pages. It is meant to enable executing code nearly as quickly as native machine code. Web Assembly allows other languages like C/C++ to be compiled to run in the browser. It has performance gains over JavaScript due to execution speed and smaller file sizes. Major browsers now support Web Assembly, allowing its use without plugins. Common use cases include games, media editing, peer-to-peer apps, and scientific/CAD applications.

Automation: The Good, The Bad and The Ugly with DevOpsGuys - AppD Summit Europe
A cornerstone of the DevOps philosophy, investment in automation at all stages across the SDLC has increased over recent years. Automation promises velocity and reduced errors, helps foster repeatable processes, and removes the need for long hours on dull, repetitive tasks. So what’s not to like? The downside of automation is that unless applied at the right place in your SDLC it can make a bad process worse. Automation also raises questions around job security, the need for re-skilling in other areas, and tool sprawl if different teams each choose their preferred technology. This session will outline:
-A short chronology of where automation has impacted the modern software stack
-Where it makes the most sense to automate (by identifying your key constraints)
-Best practices for adopting automation and how to identify where it’s working — and where it isn’t

eZ Publish 5: from zero to automated deployment (and no regressions!) in one ...
1. The workshop will cover Docker, managing environments, database changes, and automated deployments for eZPublish websites.
2. A Docker stack is proposed that includes containers for Apache, MySQL, Solr, PHP, and other tools to replicate a production environment for development. Configuration and code are mounted as volumes.
3. Managing environments involves storing settings in the code repository and using symlinks to deploy different configurations. Database changes should be managed via migration scripts rather than connecting directly to a shared database.
4. Automating deployments is important and involves tasks like updating code, the database, caches and reindexing content. The same deployment script should be used for development and production. Testing websites is also recommended.

Benefits of an Open environment with Wakanda
Wakanda is an open source platform that provides benefits of an open environment including freedom, adaptability, interoperability, portability, reusability, and community. It uses open source libraries and has open source and dual licensing. The Wakanda Studio includes tools like a model designer, GUI designer, and debugger. It supports add-ons, external widgets, and web components. The Wakanda backend integrates technologies like HTTP APIs, modules, and supports accessing external databases and technologies.
Build automation best practices
- Build automation helps ensure consistent builds, prevents errors, and speeds up the release process. It helps development teams integrate and deliver changes continuously.
- Common tools for build automation include MSBuild, Team Foundation Server, CruiseControl.NET, and Hudson. These tools help with continuous integration (CI), running tests, code analysis, versioning, and deploying builds.
- Best practices include CI on every code check-in, running unit tests as part of the build to prevent bugs, and continuously delivering integrated builds to environments for testing. This supports rapid and reliable software delivery.
Make It Cooler: Using Decentralized Version Control
A commonly used version control system in the ColdFusion community is Subversion -- a centralized system that relies on being connected to a central server. The next generation version control systems are “decentralized”, in that version control tasks do not rely on a central server.
Decentralized version control systems are more efficient and offer a more practical way of software development.
In this session, Indy takes you through the considerations in moving from Subversion to Git, a decentralized version control system. You also get to understand the pros and cons of each and hear of the practical experience of migrating projects to decentralized version control.
Version control is often used in conjunction with a testing framework and continuous integration. To complete the picture, Indy walks you through how to integrate Git with a testing framework, MXUnit, and a continuous integration server, Hudson.

Vagrant for Effective DevOps Culture
This document discusses how Vagrant was implemented at Wingify Engineering to help establish a DevOps culture. Previously, Wingify had issues with environments not matching production, difficult setups, and isolation between devs and ops. Vagrant provided developers similar environments to production using the same OS and configuration management. It simplified management through tools like "vagrant up", "vagrant ssh", and "vagrant destroy". This improved testing and reduced issues in production. It also improved collaboration by allowing ops to test configurations and devs to better understand infrastructure. Overall Vagrant helped establish closer alignment between devs and ops through shared responsibility of infrastructure.

This was a talk given at the second CT Software Developers Meetup (http://www.meetup.com/CT-Software-Developers-Meetup/). It covers how NorthPage is using Docker and Vagrant with a home grown Preview tool to increase the efficiency of the GitHub Pull Request Workflow.
Enterprise Griffon
Enterprise Griffon provides an overview of the Griffon framework, which is a desktop application framework for Java that uses plugins and addons to extend its capabilities, and it discusses Griffon's plugin architecture, MDI support, UI toolkits like SwingXBuilder and MacWidgetsBuilder, notifications, database integration, printing, and deployment options.
Tuenti Release Workflow
At Tuenti, we do two code pushes per week, sometimes modifying thousands of files and running thousands of automated tests and build operations before, to ensure not only that the code works but also that proper localization is applied, bundles are generated and files get deployed to hundreds of servers as fast and reliable as possible.
We use opensource tools like Mercurial, MySQL, Jenkins, Selenium, PHPUnit and Rsync among our own in-house ones, and have different development, testing, staging and production environments.
We had to fight with problems like statics bundling and versioning, syntax errors and of course the fact that we have +100 engineers working on the codebase, sometimes merging and releasing more than a dozen branches the same day. We also switched from Subversion to Mercurial to obtain more flexibility and faster branching operations.
With this talk we will explain the process of how code changes in ourcode repository end up in live code, detailing some practices and tips that we apply.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Hacking the way you work
- 1. Hacking the way you work: simple tools & tricks for your daily development workflow Fotis Alexandrou JOOMLADAY Greece 2013
- 2. Who am I • Developer at PeoplePerHour.com • Freelance Web Developer (Past) • Automation enthusiast • Nervous when talking in public
- 3. Challenges • Time management • Tracking changes & collaboration • Code structure • Code maintenance (the horror)
- 5. Common problems • “But it worked on my dev machine! What happened now?” • “Oh no! we use version 1.3.15 on the server? I run 2.6.13 which has the feature X implemented!”
- 6. Enter Vagrant • What it provides – Virtual Machines called “boxes” – Provisioning – Requirements: VirtualBox, Ruby
- 7. Configuration • Simple Ruby file called “Vagrantfile” – http://www.vagrantup.com/ • Plethora of pre-packaged boxes – http://vagrantbox.es • Provisioning via Puppet or Chef
- 8. Benefits • Consistency between local dev machine & production server • Ability to use the same provisioning recipes on production • Prevents from bloating the host OS with many services • Production server changes can be tested locally before being applied to production • Cloud integration (knife, vagrant aws)
- 9. Provisioning: Puppet vs Chef • Never ending discussion • Chef – Write Cookbooks in Ruby – http://docs.opscode.com/just_enough_ruby_for_chef.html • Puppet – Puppet manifests in Puppet script language • Both have the same results
- 10. Common Vagrant gotchas • Nginx + Apache sendfile (VirtualBox bug) • Memory increase – config.vm.customize ["modifyvm", :id, "--memory", 1024] • Shared folder – :extra => "umask=0002,dmask=0002,fmask=0002" • Symlinks – https://coderwall.com/p/b5mu2w
- 11. Tracking changes & collaboration
- 12. SVN vs Git • Pros – Simple flow • Cons – Brances are separate directories – Always commiting to repo – Extreme CPU usage on big repos
- 13. Enter Git • Feature branches: No separate directories for branches • Submodules • Stash • Remotes
- 14. Remote Repos • Hosted on 3rd party services – Github – Bitbucket • Can be self-hosted – Gitlab – Gitolite – Gitorious
- 15. Git • Pull requests: Non merged commits –Visual representation of changes • Squash / Rebase: Merge several commits to one – Reverting only one commit if needed
- 16. Code Structure • Design patterns – “Design patterns are reusable solutions to commonly occurring problems in software design” • Help you get a solid start
- 17. Design patterns • Not the holy grail • Help developers read each others code as structure is somehow pre-defined • Avoid duplicate code
- 18. Examples • PHP design patterns: – https://github.com/domnikl/DesignPatternsPHP • Javascript design patterns – http://addyosmani.com/resources/essentialjsdesi gnpatterns/book/
- 19. Best Practices • Avoid hacks • DELETE your code – http://www.youtube.com/watch?v=Ev7lM7SWVHE • Less code is always better • Refactor while you still code
- 20. Other tips • Embrace coding standards – https://github.com/php-fig/fig-standards/ • Exceptions are your friends – Traceable, Catchable • Read other developers’ code – Github => Facebook for developers, browse repos, even in languages you are not familiar with
- 21. Thank you • Questions • Twitter: @falexandrou • Blog: falexandrou.com
