Through Meteor to the stars - Developing full-stack SPA's with meteor.jsWekoslav Stefanovski

You've successfully learned all the ins and outs of Javascript, and can code up a website's front-end in minutes. Great. But, you always had to rely on some pesky back-end developers, with their weird way of speaking, using their weird server languages... Well, not any more - With meteor.js, you can create, build and deploy a completely complete website using only Javascript - and all from your favorite editor. Come and see the magic!

Use all the buzzwordsJared Faris

This document discusses using Backbone.js over Ruby on Rails for building web applications. It describes how the author built out different levels of an application, starting with a basic Rails app and then enhancing it with additional JavaScript frameworks like Backbone and CoffeeScript, as well as switching the database to MongoDB and adding a JSON API. The document also provides recommendations for development resources and environments for Ruby, Rails, JavaScript, and Backbone development.

みんなのNode.jsogom_

Node.js is an event-driven JavaScript runtime built on Chrome's V8 JavaScript engine. It uses an event loop model that handles asynchronous I/O efficiently by allowing non-blocking operations like networking to finish in the background while the main thread continues to run. This allows Node.js to respond quickly even under high loads with thousands of simultaneous connections without blocking. Common uses of Node.js include real-time web applications, cloud services, JavaScript development tools and build systems.

Using type script to build better appsColdFusionConference

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It allows you to write JavaScript in a more structured way using types, classes, and interfaces. Using TypeScript can help catch errors early and provide better code completion through tooling. While TypeScript adds types and other features, JavaScript code is still valid TypeScript code. The TypeScript compiler outputs plain JavaScript that runs on any browser or environment.

Concurrent Programming in iOSSam Mejlumyan

This document discusses concurrent programming and concurrency APIs on iOS. It covers threads, Grand Central Dispatch (GCD), operation queues, and challenges of concurrent programming such as race conditions, deadlocks, and priority inversion. GCD provides a low-level API for dispatching work to different queues without directly interacting with threads. Operation queues allow specifying dependencies between operations and canceling operations.

It discusses what ClojureScript is, why Clojure and JavaScript were chosen, data types, functions, macros, immutability, laziness, interactive development with REPL, core.async for concurrency, interoperability with JavaScript, Google Closure Tools, libraries like Figwheel and Devcards, shadow-cljs, and interfaces to React like Om, Reagent and Rum. It also briefly mentions desktop, mobile, Lumo and Planck.

Back to the future with static site generatorsChris Ward

If you remember when web sites were all created with plain HTML pages, then you'll know that CMSs and dynamic web frameworks saved us and solved all our problems. Or did they? In fact, we instead spend a lot of time customising existing code to meet our requirements, grappling with deployments and then whacking caching on top of over-powered servers to get an ounce of speed. Static Site Generators aim to sit somewhere in the middle and are perfect for semi-dynamic sites and with a little learning, better for content creators. In this session, Chris will look at an overview of the principles and options for static site generators and deep dive into one or two to explain further how the work and can fit into your projects.

Features & benifits of ipv6 firewallAnthony Daniel

IPv6 is an updated version of IPv4 that provides more IP addresses and improved network management. An IPv6 firewall can be configured using commands to view and set port and adapter settings for IPv6 protection. IPv6 addresses are 128-bit and can be unicast, multicast, or anycast. Unicast sends data to one device, multicast to groups, and anycast to the closest matching device. IPv6 firewalls provide benefits like more address space but challenges include more complex addresses and transition time from IPv4.

Check Point: Security in virtual environmentASBIS SK

This document discusses security in virtual and cloud environments. It begins by explaining the benefits of virtualization and private clouds for efficiency and cost reduction. It then addresses the growing problem of "VLAN sprawl" as more virtual machines are added. The document introduces Check Point's Security Gateway Virtual Edition as a solution to securely manage growing private clouds by automatically securing new virtual machines, inspecting traffic between VMs, and protecting from external threats. For public clouds, it discusses the need to securely connect, manage security within diverse cloud platforms, and secure the cloud itself with multi-tenant environments. Check Point provides unified management of physical and virtual systems as well as customized security policies to address these challenges of securing virtual and cloud computing.

IPv6Peter R. Egli

Overview of IPv6 protocol along with various transition scenarios for the migration from IPv4 to IPv6 IPv6 is the current and future Internet Protocol standard. As anticipated, IPv4 addresses became exhausted around 2012. The IP address scarcity is the main driver for IPv6 protocol adoption. IPv6 defines a much larger address space that should be sufficient for the foreseeable future, even taking into account Internet of Things scenarios with zillions of small devices connected to the Internet. IPv6 is, however, much more than simply an expansion of the address space. IPv6 defines a clean address architecture with globally aggregatable addresses thus reducing routing table sizes in Internet routers. IPv6 extension headers provide a standard mechanism for stacking protocols such as IP, IPSec, routing headers and upper layer headers such as TCP. ICMP (Internet Control Message Protocol) is already defined for IPv4. ICMP was totally revamped for IPv6 and as ICMPv6 provides common functions like IP address and prefix assignment. Lack of business drivers for migrating to IPv6 is responsible for sluggish adoption of IPv6 in carrier and enterprise networks. Numerous transition mechanisms were developed to ease the transition from IPv4 to IPv6. Many of these mechanisms are complex and difficult to administer. The transition mechanisms can be coarsely classified into dual-stack, tunneling and translation mechanisms.

The shift to the edgeJakub Wadolowski

WebAssembly became 4th official language on the Web (following HTML, CSS and JavaScript) and was initially meant to run in the browser in order to improve client side rendering. It quickly turned out that WebAssembly on the server is also a thing and can revolutionise the way we think of web applications. Fastly and Cloudflare adopted WebAssembly and allow you to run custom code at the edge. That opens up completely new possibilities - authentication, personalised content rendering, A/B testing - you name it. Everything as close to end users as possible.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
