Connecting Physical Devices to the Web - Event Driven Architecture using WebSocket for the Internet of Things

•

3 gefällt mir•822 views

Before the Web, clients connected to back-end servers without compromises. As the Web came along with HTTP, we had to give up some of the power of our connectivity. With the evolving open Web communications standards, now we have a unique opportunity to move on from a request-response based REST world to a true, event-driven architecture. Learn what it takes to connect physical devices, such as Arduino and the Rasberry Pi to collect sensor data, or control physical devices over the Web. Commercial aviation's biggest challenge when things go wrong is that flight data is stuck on the plane inside the black box. Until the black box is recovered, we barely know anything about what went wrong. This presentation offers detailed insights into how IoT and modern Web communications concepts have the power to change all this. If you're a maker, you will learn about "flight sensors" attached and controlled by Arduino, data transmitted over long range WiFi as well as satellite networks. If interested in real-time Web communications, you'll learn about a highly secure WebSocket implementation with extreme scale, publishing flight data to tablets and laptops used as monitoring dashboard. If protocol layering, enterprise messaging, or JMS is your thing, this talk is for you. Code samples and plenty of interactive live demos (with Things) add color to the talk.

Building Real-Time Enterprise Applications for the Internet of Things

Peter Moskovits

Nowadays almost everyone uses web browsers on a daily basis for various tasks such as reading emails, surfing on social networks or purchasing goods on ecommerce shops. Despite this, web developers often tend to forget that a browser is a piece of software that has deliberately been designed as a remote code execution engine, which is the dream spec for any attacker. The focus of this talk is to explain how some of the newly introduced headers (HSTS, HPKP, CSP) can help to easily add an extra layer of security in order to defend your web apps against common web security vulnerabilities. Recorded talk: https://youtu.be/i0CHVP139k4?t=4h22m7s

In a world with increasingly sophisticated adversaries employing both targeted and automated attacks, what can we do to keep our users and our web apps safe? While Rails provides pretty decent security options straight out of the box, we can go further and make attacks more difficult to accomplish. For example, why and how to implement a Content Security Policy. Should you use HTTP Public Key Pinning? How do you know if you've configured HTTPS correctly?

Websockets in Node.js - Making them reliable and scalable

Gareth Marland

Acegi Security is quickly becoming a widely respected security framework for Java applications. Not only does this security framework solve many of the deficiencies of J2EE's security mechanisms, but it's also easy to implement and configure. This tutorial will help you learn more about Acegi Security, as well as how to integrate it into your web applications. The Roller Weblogger project (currently in Apache's incubator) uses Acegi Security for many of its features: authentication, password encryption, remember me and SSL switching. After learning about Roller and Acegi, you will see how to deploy Roller onto Tomcat and Geronimo. Following that, you will learn how to hook Roller/Acegi into Apache Directory Server for authentication. Finally, you will learn how to integrate Roller with a Single Sign-on System (Yale's Central Authentication Service).

The .htaccess file is famous for helping us set redirects but it can also help improve our website’s loading times as well as help with some crawling and indexing issues that I will cover in a bit. Learn where the file can be found, how it compares to https.conf, how it can be used for redirects, deal with duplicate content, what performance issues it can encounter, how it can help you create custom 404 pages, how it helps you leverage browser caching, gzip, disable image hotlinking, add canonical tags and robots directives in the HTTP headers and what tools and resources can help you learn even more.

Shoppers are more engaged when they have access to timely and relevant information. When used for internal education, employees are more engaged and better prepared to assist customers. There are also revenue generating opportunities for those retailers who (securely) share their beacon networks. A single Eddystone-URL beacon, managed with PHY.net, can serve different content to different Physical Web browsers. In other words, retailers can lease  their beacon networks to brands. Imagine shoppers using a product’s  branded app to see rebate information… Using the store’s app offering extra  loyalty rewards if purchased today… Or an open beacon browser like Chrome,  promoting an incentive to download  the store’s branded app for sign-up  rewards points or a special coupon. Shoppers can also benefit from this app  approach if they choose to filter results in  their app and only show beacons that are  relevant to that location or brand. No worries of seeing the nail salon’s beacons  next door, or the random Twitter feed being  broadcast by another shopper’s personal beacon.

NFC vs iBeacon ? NFC+iBeacon !! 애플이 최근 NFC 관련 특허를 등록했다는 소식이 전해지면서 아이폰6에 NFC가 탑재될 가능성이 높아졌습니다. iBeacon이 등장하면서 NFC가 결국 사라질 것이라는 전망이 대두되었으나 애플이 NFC를 탑재하게된 근본적인 이유는 바로 보안입니다. NFC는 10cm이내에서만 통신이 가능하고, iBeacon은 최대 49m에서도 통신이 가능하기에 결제를 위해서는 NFC, 푸시 등을 활용한 프로모션에서는 iBeacon이라는 "합"의 논리가 나오게 됩니다. 이 NFC 시장의 새로운 패러다임을 제시할 시솔을 소개합니다!

microXchg 2019, Berlin: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware) === Please download slides if blurred! === Abstract: Only a few years ago the move towards microservice architecture was the first big disruption in software engineering: instead of running monoliths, systems were now build, composed and run as autonomous services. But this came at the price of added development and infrastructure complexity. Serverless and FaaS seem to be the next disruption, they are the logical evolution trying to address some of the inherent technology complexity we are currently faced when building cloud native apps. FaaS frameworks are currently popping up like mushrooms: Knative, Kubeless, OpenFn, Fission, OpenFaas or Open Whisk are just a few to name. But which one of these is safe to pick and use in your next project? Let's find out. This session will start off by briefly explaining the essence of Serverless application architecture. We will then define a criteria catalog for FaaS frameworks and continue by comparing and showcasing the most promising ones.

We know interactivity is the key to keep our user's interest alive but we can't reduce animation to UI anymore. Twitter, Waze, Slack... users are used to have real-time data in applications they love. But how can you turn your static API into a stream of data? By pulling? Pushing? Webhook-ing? When talking about data streaming, we often think about WebSockets. But have you ever heard of Server-Sent Events? In this talk, we will compare those technologies to understand which one you should opt for depending on your usecase and I'll show you how we have been even further by reducing the amount of data to transfer with JSON-Patch. And because real-time data is not only needed by web (and because it's much more fun), I'll show you how we can make drone dance on streamed APIs.

Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.

Foundation models are machine learning models which are easily capable of performing variable tasks on large and huge datasets. FMs have managed to get a lot of attention due to this feature of handling large datasets. It can do text generation, video editing to protein folding and robotics. In case we believe that FMs can help the hospitals and patients in any way, we need to perform some important evaluations, tests to test these assumptions. In this review, we take a walk through Fms and their evaluation regimes assumed clinical value. To clarify on this topic, we reviewed no less than 80 clinical FMs built from the EMR data. We added all the models trained on structured and unstructured data. We are referring to this combination of structured and unstructured EMR data or clinical data.
