Dark side of JS development framework
UI is the first thing which sells your application and it has been a while since we have thought to look for an alternative framework for developing UI other than Javascript. Suddenly the adoption of JS based framework like AngularJS, ReactJS, UI5 and D3JS have made Javascript the de-facto standard to create and build your UI. But is it the only option we have and the bigger question is why or why not some other tech stack replaces Javascript on UI.
Know the dark side of the Javascript frameworks for building UI, its limitation, its bad parts and learn to which extent you can push Javascript while developing UI.

Advanced Techniques for Testing Responsive Apps and Sites -- By Aakrit Prasad
** Full webinar recording: https://youtu.be/Y2MHNnWOznQ **
Responsive web design has become the preferred approach for building sites and apps that provide an optimal viewing and interaction experience on any phone, tablet, desktop or wearable device.
However, automatically testing these responsive sites and apps can be quite a challenge, due to the need to cover all supported layouts, their respective navigation, and visible content.
This presentation is part of an hands-on advanced hands-on session (https://youtu.be/Y2MHNnWOznQ) about how to effectively test apps and sites with responsive design -- and teaches you how to:
* Implement generic tests that work for all the layouts of your app
* Control the browser and viewport size in order to accurately target layout transition points
* Incorporate layout-specific assertions in your tests
* Effectively design responsive page objects
* Visually validate the correctness of your app’s layout
* Bonus: tips for planning and executing responsive website testing
Everything You Know is Not Quite Right Anymore: Rethinking Best Practices to ...
We’re entering a new era where an increasing number of devices with wildly divergent features -- including phones, tablets, game consoles, and TVs -- are connected to the Internet. As the way people access the Internet changes, there is an urgent need to rethink how we use the web to communicate. This doesn't mean creating separate solutions for each device but rather preparing our existing content to meet this increasingly unpredictable future. Dave Olsen and Doug Gapinski will share and examine examples that show how responsive design will help institutions rethink and adjust for the future-friendly web.
Primary topics that are covered are: understanding the reality of web development today, example RWD design patterns, and understanding how to test and optimize the performance of your RWD website.

130511 stop wasting_your_time
Stop wasting time with Java build tools. Large projects do not need complex build infrastructure - source code and configuration are enough. The Z2 environment works like many large business solutions by pulling source from repositories and running it without needing to rebuild. Z2 overcomes issues caused by a mismatch between project structure and runtime/deployment by making the repository structure match the runtime model. A demonstration of Z2 shows how typical Java frameworks integrate easily and development is improved through faster deployments without rebuilds.
React Native: Expectations vs Reality
I had a chance to be part of a team that started developing a decent size React Native mobile app from scratch. As a developer with a solid React background, I had some expectations at first. During my initial research, everything sounded terrific: performance stats, ease of development, learn-once-use-everywhere, debugging tools, etc. But is everything terrific really?
I'm excited to share my journey about how my expectations met the reality. I'll give my personal opinion about the matureness of the technology, for which use-cases it fits well and for which it doesn't. I'll also try to address the most popular misconceptions about React Native, which front-end developers usually have before they have the chance to actually built something.
Stop making these mistakes when using react native to build apps
Just because you’re going to hand over the task of building your app to a react native app development company doesn’t mean you can breathe a sigh of relief. You have to keep tabs on the developers to ensure they don’t make the mistakes described in this write-up.
Embracing Uncertainty: Learning to Think Responsively
This document provides an overview of responsive web design (RWD) for designers. It defines key RWD terms and discusses challenges like managing the design process for multiple screens. It offers tips on where to start with RWD, such as designing for a 768px screen first. It also covers working with writers, bosses, and coders on RWD. Recommended resources on RWD are provided at the end.
Best Practices - By Lofi Dewanto
The document outlines best practices for bootstrapping GWT projects for beginners. It recommends choosing a UI framework like GWTBootstrap3 at the start for simplicity. For microservice-based UIs, it suggests using techniques like TURDUCKEN for composition and InterApp EventBus for communication. It also provides solutions for running UIs independently by mocking services, and integrating GWT UIs into existing web apps by downloading JavaScript. The summary emphasizes that GWT remains well-suited for Java-based single page apps due to its programming model and ability to use Java semantics. It also notes that table/grid components and documentation could be improved.
Two approaches to RWD: Pure & Hybrid. Brendan Falkowski
This document discusses two approaches to responsive web design: pure RWD and hybrid approaches using techniques like responsive proxies, adaptive layouts, and responsive design with server-side components (RESS). It provides an overview and comparison of these techniques, including insights from a survey of RESS users. Key advantages of pure RWD include a single URL, no redirects, and better crawler efficiency, though other hybrid approaches can also be viable depending on a site's needs and resources.
Which Postgres is Right for You?
If you are unsure, which Postgres is right for you, rest assured that others have faced the same challenge. Based on EDB's work with other Postgres users we have developed a guide providing you with the pros and cons of various Postgres solutions so that you can make an educated decision.
This presentation reviews the following scenarios based on usage profiles and the technical and business risks involved:
- PostgreSQL without commercial support
- Creating your own PostgreSQL fork
- PostgreSQL with a consulting partner
- EDB Postgres Standard
- EDB Postgres Enterprise
This presentation will help you select which level of tooling and support is appropriate for your particular use case.
Target Audience:
This presentation is intended for decision-makers and IT leaders who are in the process of evaluating PostgreSQL and EDB Postgres. The knowledge of differences between the solutions discussed will assist in selecting the right database to support your current operations and plans for growth.

Proud to be polyglot
New developers and teams are now polyglot :
- they use multiple programming languages (Java, Javascript, Ruby, ...)
- they use multiple persistence store (RDBMS, NoSQL, Hadoop)
In this talk you will learn about the benefits if being polyglot: use the good language or framework for the good cause, select the good persistence for specific constraints.
This presentation will show how developer could mix the Java platform with other technologies such as NodeJS and AngularJS to build application in a more productive way. This is also the opportunity to talk about the new Command Query Responsibility Segregation (CQRS) pattern to allow developers to be more effective and deliver the proper application to the user quicker.
This presentation was delivered during Devfest Nantes 2014
Real World Application of Development
This document provides information about the author's background and experience in development. It then discusses projects completed at SCPS and tools used. Key points about the current state of development are outlined, followed by the "three pillars" of development: degree, experience, and certifications. Important skills, languages, and career path/timeline are recommended. The future of development is also briefly discussed.
ImthiyazAli_Resume
This document contains a summary of a senior developer's qualifications and experience. It includes details about 6 years of experience in Java/J2EE development, business analysis, and training coordination. It also lists the developer's educational background and provides summaries of 4 projects they worked on, highlighting technologies used and responsibilities like requirements analysis, development, and defect fixing. Contact information is also included at the bottom.
corporateJavascript
This document discusses the role of JavaScript in large non-tech corporations. It addresses both challenges (e.g. tight deadlines, lack of understanding from managers) and opportunities (e.g. using modern tools/frameworks to solve real problems and evangelize JavaScript's capabilities). The author advocates delivering value quickly using frameworks like Backbone.js or AngularJS, data visualization libraries, and best practices like decoupling front-end and back-end code. The goal is to help corporations modernize their JavaScript use in a sustainable way.

PykQuery is a conceptual framework that help organise complexity around data-driven interactive single page apps.
Measuring Web Performance - HighEdWeb Edition
Today, a Web page can be delivered to desktop computers, televisions, or handheld devices like tablets or phones. While a technique like responsive design helps ensure that our websites look good across that spectrum of devices we may forget that we need to make sure that our websites also perform well across that same spectrum. More and more of our users are shifting their Internet usage to these more varied platforms and connection speeds with some moving entirely to mobile Internet. In this session, we’ll look at the tools that can help you understand, measure and improve the performance of your websites and applications. The talk will also discuss how new server-side techniques might help us optimize our front-end performance. Finally, since the best way to test is to have devices in your hand, we’ll discuss some tips for getting your hands on them cheaply. This presentation builds upon Dave Olsen’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.”
The Great Debate: PostgreSQL vs MySQL
This document summarizes a presentation comparing PostgreSQL and MySQL databases. It outlines the strengths and weaknesses of each, including PostgreSQL's strong advanced features and flexible licensing but lack of integrated replication, and MySQL's replication capabilities but immature security and programming models. It also discusses common application types for each database and provides an overview of the EnterpriseDB company.

Android App Performance
Avoid creating unnecessary objects to reduce garbage collection. Direct field access is faster than getter/setters. Make methods static when possible for faster invocation without object state changes. Use static final for constants. Enhanced for loops are faster than iterables. Recycle complex objects like bitmaps. Avoid floating point if possible and prefer double over float. Leverage libraries like System.arrayCopy() rather than reimplementing. Use ViewHolder pattern for lists. Native code is not always more efficient and should only be used for existing native code, not to speed up Java code. Background tasks can use threads, handlers, broadcast receivers or AlarmManager. Layouts can be reused with <include> and <merge> tags.
Usability in the GeoWeb
This document discusses how web design firms can compete with internal GIS teams by providing web-based GIS (WebGIS) applications. It notes that WebGIS requires learning new tools like JavaScript, AJAX, and RESTful services. To protect their work, internal GIS teams need to learn these new web technologies and prioritize usability over features to create responsive applications. The document advocates for an iterative development process with a focus on performance and usability testing.
Workshop About Software Engineering Skills 2019

2. Popular emerging technologies including frontend solutions at Grab and SMAC technologies (Social, Mobile, Analytics, Cloud, IoT).
3. Skills needed for software engineers in 2019 including methodologies for software design, programming, requirements analysis, and development.
Tools and best practices for sustainable software
This document provides an overview of tools and best practices for sustainable software engineering. It begins with defining sustainability in the context of software and hardware. It then outlines several open-source tools that can measure software resource consumption, such as energy usage and machine utilization. These include Scaphandre, codecarbon.io, Kepler, and the Green Metrics Tool. The document discusses interpreting data from these tools and some debated best practices, such as right-sizing VMs and stateless design. It concludes that the most important practices are to quantify your system's resource usage and treat energy and emissions as key metrics.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
Use PyCharm for remote debugging of WSL on a Windo cf5c162d672e4e58b4dde5d797...
This document serves as a comprehensive step-by-step guide on how to effectively use PyCharm for remote debugging of the Windows Subsystem for Linux (WSL) on a local Windows machine. It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
