Joseph Ardolino is a senior software engineer with over 12 years of experience building quality software using technologies including Java, C#, .NET, SQL Server, Oracle, MongoDB, Redis, Linux, Windows, and more. He currently works at Moneysupermarket where he has implemented REST services, authentication systems, caching strategies, ETL processes, and cloud deployments on AWS. Previously he held software engineering roles at Peninsula Business Services, Swinton Insurance, Laterooms, and Moneysupermarket where he delivered projects using agile methodologies.
What do the terms serverless, containers, and virtual machines mean? Which should I use to build my app? The answer (as always) is "it depends." In this session learn the tradeoffs between these different approaches, whether you're building your app from scratch or want to move an existing web or mobile application to the cloud. We'll discuss open source tools such as Kubernetes, Istio, and Knative, and we'll discuss Google Cloud Platform tools like Compute Engine, Google Kubernetes Engine (GKE), App Engine, and Cloud Functions.
The document discusses how the NetBeans IDE can help developers quickly integrate HTML5 with Java EE 7. It provides an overview of the HTML5 platform and tools available in NetBeans for working with HTML5, JavaScript, CSS, and mobile development. NetBeans also offers robust support for Java EE, including features for JSON processing, web sockets, concurrency, batch processing, and RESTful web services. The document emphasizes how NetBeans improves developer productivity and provides seamless integration between HTML5, Java EE, and other technologies. It concludes with an invitation to try the free tools and a contact for the author.
The document compares the performance of JavaScript engines in different browsers. It discusses the V8 engine in Google Chrome, SpiderMonkey in Firefox, Chakra in Internet Explorer 9, and Carakan in Opera 11. Benchmarks show that V8 consistently outperforms the other engines, with Chrome 16 being 2-5 times faster than Firefox, Internet Explorer, and Opera in the Kraken and V8 benchmarks. The document attributes V8's performance to optimizations like hidden classes, dynamic code generation, and its garbage collector.
Isomorphic JavaScript applications can share the same code and run on both the front end and back end. It is also a spectrum containing applications that share minimal bits of validation logic with ones that share a bulk of the application code. Nashorn is a new JavaScript engine for Java that was released with Java 8. The Nashorn JavaScript engine makes isomorphic web apps on the JVM possible by allowing the exact same browser code to run on the server. This enables us to achieve the don’t-repeat-yourself (DRY) principle, by reducing repetition in a multitier architecture. This presentation covers the key concepts, rationale, and categories of Isomorphic JavaScript and how it makes your large applications maintainable.

Browsers and Web Runtimes for Automotive: Alternatives, Challenges, and Curre...Igalia
By Juan José Sánchez Penas.
Automotive web browsers and web application runtimes have specific needs, compared to platforms such as mobile, STB/TV, desktop and other embedded devices.
When building your own web middleware for an automotive platform, many different aspects need to be considered in order to define the right technologies, the architecture to be used, and a good strategy regarding the collaboration with open source projects and communities.
In this talk we will discuss those aspects, focusing specifically on WebKit and Chromium, the two main technologies that are being used to build and derive browsers and web runtimes.
We will review the alternatives and their status, describe the challenges, explain the functionality and performance, and show demos based on our work at Igalia developing and adapting browsers for automotive, in the context of AGL
(Automotive Grade Linux) and GENIVI.

Chrome v8 web: the open source javascript
1. Chrome v8 web
assembly engine
Presentation by Abin E Sajeev
Class:S6 Computer science
Register no:210021028032
2. What is v8?
● V8 is Google’s open source high-performance JavaScript and WebAssembly engine
● It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and
Linux systems that use x64, IA-32, ARM, or MIPS processors.
3. ● V8 is a free developed by the Chromium Project for Chromium and Google Chrome web
browsers.
● The project’s creator is Lars Bak. The first version of the V8 engine was released at the
same time as the first version of Chrome: 2 September 2008. It has also been used on the
server side
4. V8 can run standalone, or can be embedded into
any C++ application
V8 is written in C++ and is used in Google
Chrome
5. Function of v8
● V8 compiles and executes JavaScript source code, handles memory allocation for objects, and garbage
collects objects it no longer needs. V8’s stop-the-world, generational, accurate garbage collector is one
of the keys to V8’s performance.
● V8 enables any C++ application to expose its own objects and functions to JavaScript code. It’s up to
you to decide on the objects and functions you would like to expose to JavaScript.
6. Working of v8
● V8 translates JavaScript code directly into machine code so that computers can actually understand it,
then it executes the translated, or compiled, code. V8 optimizes JavaScript execution as well.
7. From a high-level view, the V8
JavaScript engine execution
consists of 5 steps.
• Initialize environment in the
host
• Compile JavaScript codes
• Generate bytecodes
• Interpret and execute
bytecodes
• Optimize some bytecodes for
better performance
8. Components of v8
● The V8 engine gets its speed from the Just in Time (JIT) compilation of JS code to native machine code.
● The ignition interpreter, a key component of V8, compiles the JS code and generates non-optimized
machine code. On runtime, the machine code is analyzed and re-compiled for optimal performance.
● This optimization is handled by the TurboFan and Crankshaft components of V8.
9. Ignition:
Ignition is V8’s interpreter, responsible for quickly parsing and executing JavaScript code. It utilizes
bytecode rather than directly interpreting the source code, which helps in speeding up the initial execution.
It generates bytecode from the Abstract Syntax Trees (ASTs) produced by the Parser. This bytecode is
executed more efficiently than the original source code.
Ignition also collects profiling information about the code’s behavior during the initial execution phase,
providing valuable data to optimize critical parts of the code later.
10. TurboFan:
TurboFan is V8’s optimizing compiler, which takes advantage of the profiling information gathered by
Ignition.
It optimizes the bytecode generated by Ignition by analyzing the profiling data. TurboFan aims to generate
highly optimized machine code tailored to the specific execution profile of the JavaScript.
TurboFan optimizes critical paths in the code, applying sophisticated optimization techniques to further
enhance performance.
This component focuses on producing optimized machine code for performance-critical sections of the
JavaScript program, thereby improving overall execution speed.
11. Alongside the above-mentioned components, V8 engine has a few other important
components, namely Liftoff and Orinoco.
• Liftoff is responsible for machine code generation and performs its tasks in a highly optimized
fashion. It’s a simpler code generator that generates code for each opcode and performs ten
times better than TurboFan.
• Orinoco is responsible for garbage collection. Its job is to look for disconnected memory
allocations and perform evacuation and compaction to free up space for more objects. Orinoco
also updates pointers to new memory locations and marks the living objects in black to speed
up the iterative marking process.
12. V8 optimizes code execution
• V8 had two main execution tiers: Ignition, the interpreter; and TurboFan, V8’s optimizing
compiler focused on peak performance.
• All JavaScript code is first compiled to ignition bytecode, and executed by interpreting it.
• During execution V8 tracks how the program behaves, including tracking object shapes and
types.
• Both the runtime execution metadata and bytecode are fed into the optimizing compiler to
generate high-performance, often speculative, machine code that runs significantly faster
than the interpreter can.
13. What
is
Node.js?
Node.js is a runtime environment for executing JavaScript code, and
it is built on the Chrome V8 engine. It is asynchronous, which means
that it does not have to wait for one process to complete before
starting another one. Like V8, Node.js is free and open-source
