“If Tetris has taught me anything, it’s that errors pile up and accomplishments disappear” is a common quote and it seems we’re living this to its full extend as web developers. We fail to celebrate the successes we have and the tools that are at our disposal but we’re never short of finding reasons why things don’t work. We also tend to pile on technology on technology to solve problems that may actually not exist and thus clog up the web. In this talk Chris Heilmann wants to remind us what we achieved and how we should celebrate it and how we should stop trying to solve problems that are simply beyond our control.
2021 Chrome Dev Summit: Web Performance 101Tammy Everts
What do we mean when we talk about "web performance"? Why should you care about it? How can measure it? How do you get other people in your organization to care? In this workshop at the 2021 Chrome Dev Summit, I covered these questions – including an overview of the history of performance metrics, up to Core Web Vitals.

Stefan Judis "Did we(b development) lose the right direction?"Fwdays
Keeping up with the state of web technology is one of the biggest challenges for us developers today. We invent new tools; we define new best practices, everything’s new, always... And we do all that for good user experience! We do all that to build the best possible web – it’s all about our users.
But is it, really? Or do developers like to play with technology secretly loving the new and shiny? Or do we only pretend that it’s about users, and behind closed doors, it’s developer experience that matters to us? Did we lose direction? Is it time for a critical look at the state of the web and the role JavaScript plays in it?
How slow load times hurt UX (and what you can do about it) [FluentConf 2016]Tammy Everts
There are compelling arguments why companies need to care about serving faster pages to their users. Countless studies have found an irrefutable connection between load times and key performance indicators, ranging from page views to revenue.
In this talk, I outlined research-based reasons why you need to care about web performance and what you can do to make your pages faster. Your takeaways (I hope) will be an understanding of why improving load times is critical to delivering better online experiences and how to identify and fix common performance leeches on your pages.
Topics include:
- User expectations
- The impact of load time on business metrics (revenue, conversions, bounce rate, and user satisfaction/retention)
- The insidiousness of “page bloat”
- 19 things you can do to deliver a faster user experience
Measuring Web Performance (HighEdWeb FL Edition)Dave Olsen
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 web sites look good across that spectrum of devices we may forget that we need to make sure that our web sites 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 web performance of your web sites 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’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.”

Cloud Connect Santa Clara 2013: Web Acceleration and Front-End Optimization (...Strangeloop
One approach to performance is to accelerate the network; another is to optimize the application by reducing how much the network is needed and pushing content out towards the user. In this session, Hooman Beheshti reveals how technologies like Front-End Optimization and Content Delivery Networks work alongside the rest of the cloud computing stack to improve performance and increase user productivity.
When Web Performance Optimization was emerging as a new field of engineering we had a handful of rules to follow. Gzip here, minify there, do some caching. This was 15 years ago.
This year’s Smashing Magazine performance checklist has 62 items with hundreds of links for further research.

A brownbag presentation at IPC media in London about the need to use libraries to make web development much less random and more professional. Get the audio at: http://www.archive.org/details/ProfessionalWebDevelopmentWithLibraries
Dans cette présentation, Chris Heilmann nous parlera des problèmes liés à l'adoption de standards du web récents, et décrira des façons de contourner ces difficultés. Un exemple simple est le manque de prise en charge native de l'audio et de la vidéo, et les problèmes des implémentations actuelles.
La session illustrera concrètement comment régler des problèmes a priori sans solution en les attaquant sous un autre angle. Il s'agit essentiellement de trouver une façon pragmatique de vendre, implémenter et utiliser les standards plutôt que d'attendre que le marché adopte des technologies dont l'utilisation devrait être d'une évidence complète.

These days, you can’t swing a dry erase marker without hitting someone talking about microservices. Developers are studying Eric Evans' prescient book, Domain-Driven Design. Teams are refactoring monolithic apps, looking for bounded contexts and defining a ubiquitous language. And although there have been countless articles, videos, and talks to help you convert to microservices, few have spent any appreciable time asking if a given application should be a microservice. In this talk, I‘ll show you a set of factors you can apply to help you decide if something deserves to be a microservice or not. We’ll also look at what we need to do to maintain a healthy micro(services)biome.

devops, platforms and devops platformsVMware Tanzu
Everyone has a platform. The choice is not between having a platform or not, the choice is between having an ad hoc organic platform or a deliberate structured platform. An army of administrators running scripts is a platform. The emergence of system automation tools provided powerful abstractions to increase the velocity and consistency beyond traditional approaches, but left orchestration and integration to be accomplished by additional scripts or manual processes. These tools and processes formed new platforms for deploying and managing software services. The new automation frameworks, like Cloud Foundry, represent the first generation developed after the advent of api driven cloud computing. This presentation will walk through the evolution of systems and software, the emergence of the process and practices driving innovation at scale, highlight the patterns of successful platforms leveraging both technology and people to deliver value with practical advice for evaluating and implementing change in the context of your organization.

Devops, Continuous Delivery, Microservices, Platforms, what does it all mean?
TL;DR
Automation is a function of what is being automated. Ad hoc automation will not solve deployment and operational problems as much as being thoughtful about the architectures being deployed. The technology and the people mirror each other's communication.
In this session, we will explore the how the recent explosion of devices has disrupted the process of designing a website that we've crafted over the past decade.
When designers only have one instance of website (i.e., desktop) to design, the layout is uniform. The header, content area, sidebar, and footer all remain static. Furthermore, the elements are relatively uniform as well. Buttons, navigation, typography, and images are all basically the same across across the various pages. But if you are designing a responsive website – one whose look and feel adapts depending whether you're using a phone, laptop, or tablet – then these elements and especially the layout begin to diverge.
After this session, you should leave with the confidence to argue the importance of responsive design to your client or boss – and that the with the proper strategy, the extra effort and costs can be justified (and hopefully minimized).

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
