Presented at FITC Toronto 2019 More info at www.fitc.ca/toronto Chris Zacharias imgix Overview The average website loads over 1.5MBs of content per page, making over 75 requests. Many popular websites are serving over 5MBs just to load their homepages. And these numbers represent measurements taken AFTER compression is applied. The full weight of many popular websites is pushing 20+ MBs these days. In an era where performance truly matters to the end user experience, web developers need techniques to help curtail this bloat in data down the wire. No matter how well you optimize, there is no better way to than to delete things you do not need. How does one determine what is essential to the user experience and what is not? One answer Chris posits is to develop a hyper-lightweight version of your website which will provide critical insights into your specific performance priorities. This is a process that he has leveraged on many projects, in particular at YouTube to reduce the size of the video watch page from 1.5MBs to 100KBs. In this talk, Chris will take real-world web pages and show techniques for dramatically reducing their page weight and for identifying areas to optimize, while outlining the key steps to doing this well. Objective Learn a process for building a hyper-lightweight version of your website for establishing reasonable performance budgets, grounded in reality, to work from. Target Audience Web developers Assumed Audience Knowledge HTML, CSS, Javascript, some server-side awareness. Level Intermediate Five Things Audience Members Will Learn How to analyze a web page for performance issues A holistic approach to deconstructing an existing website A clear process for building a hyper-lightweight version of your website Translating your findings into real performance priorities Establishing a realistic performance budget

Speed is essential for a good user experience on the web. Research has shown that page load times over 1 second can negatively impact user behavior like concentration and abandonment rates. Factors that affect page load times include front-end code, images, third-party scripts, redirects, and HTTP requests. Key ways to improve performance include optimizing front-end code, compressing images, loading scripts asynchronously, minimizing redirects, caching resources, and measuring real user performance. The goal is to provide users with fast response times across all devices.

From my presentation "I feel the need..the need for speed: Optimizing the User Experience", given at UXPA Boston 2014. This is the second half of the talk. The first half (are we slow? How slow? Why? And Why That's a Problem) used a ton of animation and rapid patter, and just doesn't make much sense on SlideShare without audio. I need to upload that to YouTube, someday.

This document summarizes strategies for optimizing a website's user experience by improving page load speeds. It discusses researching current page speeds and user locations/devices, setting performance goals, optimizing technologies like images, scripts and caching, improving information architecture to reduce page sizes, addressing trends that slow performance, and visual design techniques to decrease file sizes like using illustrations and CSS sprites. The overall message is that digital strategies must prioritize speed optimization to meaningfully improve the user experience.

Understanding what happens on the client side is not easy. When you user visits your website you need to check his location, his device, connection speed, browser, and what page he is visiting. After gathering all this data, you also need to check what happened. How long it takes for him to see the page? How long it takes until the page is fully loaded and working? If there was a JS error what was it and why can’t you replicate it? Most of the users don’t have powerful machines, with fast-connections. In this talk we will analyze the tools you can use to profile the client, synthetic and RUM analysis and how you can improve the performance on the client side. Basic and more advanced tips with real examples.

This document discusses 4 simple optimizations that can be made to images on websites to improve performance: 1) Reducing image quality, 2) Using optimized file formats like JPEG, WebP and SVG, 3) Resizing images to actual display size, and 4) Implementing lazy loading so images outside the viewport are not downloaded. It provides examples and data on how each technique can significantly reduce data usage and improve load times.

Steve Souders' talk at SpeedGeeks L.A. about new performance numbers from big players, his latest tool developments and importance of progressive enhancement.

The document discusses the importance of frontend website performance. It provides examples showing that speeding up websites by even small amounts, such as 0.4 seconds, can significantly increase metrics like search traffic, revenue, and reduce bandwidth usage. The document recommends techniques for improving performance like concatenating files, minifying files, using content delivery networks, browser caching, and reducing redundant content. It also discusses tools for analyzing website performance.

This document discusses ways to improve web performance for mobile users. It outlines goals like achieving a speed index between 1,100-2,500 and first meaningful paint within 1-3 seconds. Various techniques are presented for hacking first load times, data transfer, resource loading, images and user experience. These include avoiding redirects, using HTTP/2 and service workers, modern cache controls, responsive images, preloading resources, and ensuring consistent frame rates. The overall message is that mobile performance needs more attention given average load times and high bounce rates on slow mobile sites.

Web Sites are to slow and this is costing businesses money. Most performance issues are easy to fix. In this session we review why web performance is important and 10 simple things you can do to make a faster user experience.

Shopzilla redesigned their architecture to improve performance and scalability. The new design simplified layers, utilized caching extensively, and applied best practices for front-end performance. This led to significant business benefits including a 7-12% increase in conversion rates, 8-120% increase in search engine sessions, and a 225% increase in development velocity. Performance testing was a key part of the new approach.

The document discusses optimizing images for fast delivery on mobile websites. It recommends 4 simple optimizations: 1) reducing image quality to 85%, 2) using efficient formats like JPEG, PNG and WebP, 3) sizing images appropriately for different screens, and 4) lazy loading images below the fold. Implementing these optimizations can significantly reduce data usage and speed up page loads. The document also provides tips on vector images, responsive images and converting animated GIFs to video.

The document discusses optimizing web performance. It begins by defining critical rendering path optimization, which involves identifying the minimum CSS needed to render the initial viewport of a page. This critical CSS can be inlined into the page head to avoid an additional HTTP request. Non-critical CSS is then preloaded asynchronously so it downloads in parallel without blocking page rendering. Tracking paint metrics like first contentful paint and time to interactive is also recommended to measure performance improvements. Overall, the document emphasizes optimizing the critical resources needed for the initial page load.

Performance is fundamentally, a UX concern. Sites that are slow to render or janky to interact with are a bad user experience. We strive to write performant code for our users, but users don’t directly interact with our code - it all happens through the medium of the browser. The browser is the middleman between us and our users; therefore to make our users happy, we first have to make the browser happy. But how exactly do we do that? In this talk, we’ll learn how browsers work under the hood: how they request, construct, and render a website. At each step along the way, we’ll cover what we can do as developers to make the browser’s job easier, and why those best practices work. You’ll leave with a solid understanding of how to write code that works with the browser, not against it, and ultimately improves your users’ experience.

Design Systems are most successful when they have a solid process in place to manage, maintain, and share component code across multiple teams and codebases. The best way to achieve this is to manage code using a version control system like Git. Git is the defacto industry standard tool for storing and editing code for a reason - it's powerful, scalable, flexible... but can be confusing or intimidating, whether you're a newbie or you use it every day! In this workshop, Katie Sylor-Miller, the creator of OhShitGit.com, and co-author of The Design Systems Handbook, will teach you all you need to know to use Git as a tool for managing your Design System code. We'll walk through everything you need to know to create, contribute to, maintain, and share your design system code as a standalone repo in Git. We'll go over how the fundamental structures in Git and how it all works under the hood. We'll create our own repos and get comfortable running common git commands in the terminal. We'll learn about best practices, workflows, and tools that will keep your commits in order and reduce the panic caused by merge conflicts. And, we'll cover some cool features in the Github UI to help you document, manage, and share your Design System code.

We developers and designers are obsessed with getting our images “just right” before we display them to our users. We perfect their art direction, selecting images that set the right mood or convey the right information. We fine-tune their performance characteristics and ensure that we serve the right image for a multitude of devices. But what about users who can’t see our finely-tuned images or distinguish between the colors in our beautiful infographics? How do we ensure that our images are accessible so that everyone can experience your site to the fullest ? In this session, we’ll learn about the different types of visual, auditory, cognitive, and motor impairments that affect how users interact with images and other media, and we’ll cover practical techniques for ensuring that your images are accessible to everyone, regardless of how they experience the web.

Git, the widely popular version control tool that just about everyone who works on the web seems to use, is powerful, scalable, flexible. . .and difficult to learn. If you’ve used Git for any amount of time, you’ve probably gotten yourself into some confusing, frustrating, or downright terrifying situations. But don’t panic. You are not alone. Katie Sylor-Miller explains how to avoid getting into Git messes in the first place, demonstrating how the fundamental structures in Git actually work under the hood and sharing best practices, workflows, and tools that will keep your commits in order and reduce the panic caused by merge conflicts. Katie then shows you how to leverage Git’s powerful features to save yourself when everything seems to go wrong.

Image recognition, which comes under Artificial Intelligence (AI) is a critical aspect of computer vision, enabling computers or other computing devices to identify and categorize objects within images. Among numerous fields of life, food processing is an important area, in which image processing plays a vital role, both for producers and consumers. This study focuses on the binary classification of strawberries, where images are sorted into one of two categories. We Utilized a dataset of strawberry images for this study; we aim to determine the effectiveness of different models in identifying whether an image contains strawberries. This research has practical applications in fields such as agriculture and quality control. We compared various popular deep learning models, including MobileNetV2, Convolutional Neural Networks (CNN), and DenseNet121, for binary classification of strawberry images. The accuracy achieved by MobileNetV2 is 96.7%, CNN is 99.8%, and DenseNet121 is 93.6%. Through rigorous testing and analysis, our results demonstrate that CNN outperforms the other models in this task. In the future, the deep learning models can be evaluated on a richer and larger number of images (datasets) for better/improved results.

Pre-trained Large Language Models (LLM) have achieved remarkable successes in several domains. However, code-oriented LLMs are often heavy in computational complexity, and quadratically with the length of the input code sequence. Toward simplifying the input program of an LLM, the state-of-the-art approach has the strategies to filter the input code tokens based on the attention scores given by the LLM. The decision to simplify the input program should not rely on the attention patterns of an LLM, as these patterns are influenced by both the model architecture and the pre-training dataset. Since the model and dataset are part of the solution domain, not the problem domain where the input program belongs, the outcome may differ when the model is trained on a different dataset. We propose SlimCode, a model-agnostic code simplification solution for LLMs that depends on the nature of input code tokens. As an empirical study on the LLMs including CodeBERT, CodeT5, and GPT-4 for two main tasks: code search and summarization. We reported that 1) the reduction ratio of code has a linear-like relation with the saving ratio on training time, 2) the impact of categorized tokens on code simplification can vary significantly, 3) the impact of categorized tokens on code simplification is task-specific but model-agnostic, and 4) the above findings hold for the paradigm–prompt engineering and interactive in-context learning and this study can save reduce the cost of invoking GPT-4 by 24%per API query. Importantly, SlimCode simplifies the input code with its greedy strategy and can obtain at most 133 times faster than the state-of-the-art technique with a significant improvement. This paper calls for a new direction on code-based, model-agnostic code simplification solutions to further empower LLMs.

This is research about a process called field-oriented control (FOC) that is used to control the pmsm motor.
