Vlad zelinschi optimizing the critical rendering pathCodecamp Romania

The document discusses optimizing the critical rendering path (CRP) of a web page. The CRP refers to the steps between receiving HTML, CSS, and JavaScript and rendering pixels on the screen. These steps include parsing HTML to build the DOM tree, parsing CSS to build the CSSOM tree, combining them into a render tree, running layout to compute geometry, and painting to the screen. Optimizing the CRP means minimizing the time spent in these steps. Some tips include getting CSS to the client fast, eliminating blocking JavaScript from the CRP, and focusing on above-the-fold content. Tools like critical CSS extraction can help optimize the CRP.

FULL stack -> MEAN stackAshok Raj

Node js Krishna Chaytaniah

Node.js is a JavaScript runtime environment that uses Google Chrome's V8 engine. It allows for high concurrency without threads or processes by using an event loop and callbacks for non-blocking I/O. While it can be used for server-side JavaScript applications, its lack of access to the DOM from the server-side presents some drawbacks compared to traditional client-side JavaScript. Overall, Node.js enables highly scalable applications but its non-blocking nature requires some adjustment for developers accustomed to blocking I/O models.

WebAssembly vs JavaScript: What is faster?Alexandr Skachkov

- WebAssembly is a new low-level compilation target that runs at native speed by taking advantage of common hardware capabilities available on a web platform. - While WebAssembly is very fast for pure computations, calling JavaScript from WebAssembly can lead to slowdowns. Interacting with the DOM or host APIs may also be slower than native code. - WebAssembly is best suited for applications that require a lot of computation, are developed with a focus on performance, and have minimal interactions with JavaScript or the DOM. This includes porting existing C/C++ libraries and algorithms to the web.

How John started to like TDD (instead of hating it) (ViennaJUG, June'25)Nacho Cougil

Let me share a story about how John (a developer like any other) started to understand (and enjoy) writing Tests before the Production code. We've all felt an inevitable "tedium" when writing tests, haven't we? If it's boring, if it's complicated or unnecessary? Isn't it? John thought so too, and, as much as he had heard about writing tests before production code, he had never managed to put it into practice, and even when he had tried, John had become even more frustrated at not understanding how to put it into practice outside of a few examples katas 🤷‍♂️ Listen to this story in which I will explain how John went from not understanding Test Driven Development (TDD) to being passionate about it... so much that now he doesn't want to work any other way 😅 ! He must have found some benefits in practising it, right? He says he has more advantages than working in any other way (e.g., you'll find defects earlier, you'll have a faster feedback loop or your code will be easier to refactor), but I'd better explain it to you in the session, right? PS: Think of John as a random person, as if he was even the speaker of this talk 😉 ! --- Presentation shared at ViennaJUG, June'25 Feedback form: https://bit.ly/john-like-tdd-feedback

zOS CommServer support for the Network Express feature on z17zOSCommserver

The IBM z17 has undergone a transformation with an entirely new System I/O hardware and architecture model for both storage and networking. The z17 offers I/O capability that is integrated directly within the Z processor complex. The new system design moves I/O operations closer to the system processor and memory. This new design approach transforms I/O operations allowing Z workloads to grow and scale to meet the growing needs of current and future IBM Hybrid Cloud Enterprise workloads. This presentation will focus on the networking I/O transformation by introducing you to the new IBM z17 Network Express feature. The Network Express feature introduces new system architecture called Enhanced QDIO (EQDIO). EQDIO allows the updated z/OS Communications Server software to interact with the Network Express hardware using new optimized I/O operations. The new design and optimizations are required to meet the demand of the continuously growing I/O rates. Network Express and EQDIO build the foundation for the introduction of advanced Ethernet and networking capabilities for the future of IBM Z Hybrid Cloud Enterprise users. The Network Express feature also combines the functionality of both the OSA-Express and RoCE Express features into a single feature or adapter. A single Network Express port supports both IP protocols and RDMA protocols. This allows each Network Express port to function as both a standard NIC for Ethernet and as an RDMA capable NIC (RNIC) for RoCE protocols. Converging both protocols to a single adapter reduces Z customers’ cost for physical networking resources. With this change, IBM Z customers can now exploit Shared Memory Communications (SMC) leveraging RDMA (SMC-R) technology without incurring additional hardware costs. In this session, the speakers will focus on how z/OS Communications Server has been updated to support the Network Express feature. An introduction to the new Enhanced QDIO Ethernet (EQENET) interface statement used to configure the new OSA is provided. EQDIO provides a variety of simplifications, such as no longer requiring VTAM user defined TRLEs, uses smarter defaults and removes outdated parameters. The speakers will also cover migration considerations for Network Express. In addition, the operational aspects of managing and monitoring the new OSA and RoCE interfaces will be covered. The speakers will also take you through the enhancements made to optimize both inbound and outbound network traffic. Come join us, step aboard and learn how z/OS Communications Server is bringing you the future in network communications with the IBM z17 Network Express feature.

Microsoft Azure is a cloud platform that empowers businesses with scalable computing, data analytics, artificial intelligence, and cybersecurity capabilities. Arguably the biggest hurdle for most organizations is understanding how to get started. Microsoft Azure is a consumption-based cloud service. This means you pay for what you use. Unlike traditional software, Azure resources (e.g., VMs, databases, storage) are billed based on usage time, storage size, data transfer, or resource configurations. There are three primary Azure purchasing models: • Pay-As-You-Go (PAYG): Ideal for flexibility. Billed monthly based on actual usage. • Azure Reserved Instances (RI): Commit to 1- or 3-year terms for predictable workloads. This model offers up to 72% cost savings. • Enterprise Agreements (EA): Best suited for large organizations needing comprehensive Azure solutions and custom pricing. Licensing Azure: What You Need to Know Azure doesn’t follow the traditional “per seat” licensing model. Instead, you pay for: • Compute Hours (e.g., Virtual Machines) • Storage Used (e.g., Blob, File, Disk) • Database Transactions • Data Transfer (Outbound) Purchasing and subscribing to Microsoft Azure is more than a transactional step, it’s a strategic move.
