We all know Mobile is different, but by how much?
This presentation attempts to quantify the difference between mobile and non-mobile, focusing on CPU, network and browser differences.
Velocity 2012: The 90-Minute Mobile Optimization Life CycleStrangeloop
Strangeloop VP Technology Hooman Beheshti demonstrates – in real time – the impact of advanced mobile optimization techniques on another unsuspecting website.
Over the course of the workshop, witness the mobile optimization life cycle, from start to finish:
- Taking the “Before” shot: Choosing a guinea pig site and benchmarking its current performance, focusing on load time, start render time and round trips.
- Iterating through core best practices, including: Keep-Alive, Compression, Far Future Expiry, and Use a CDN.
- Applying a set of advanced, automated, mobile-specific FEO techniques.
- Taking the “After” shot: Analyzing results using different browsers.
Your visitors interact with content, not with your website. Content consistency is crucial to a successful user experience. Re-publishing is one option but it’s an inside-out action that relies on the authority controlling where the information goes. An API frees your data and the responsibility to where it is published and accessed. Mobile is a major consumer for your API but not every API is setup to handle the mass of requests coming from those devices. Learn how to mobile devices consume API’s with limited or low bandwidth and how to to tailor your API to be as efficient and effective as possible.

Everyone loves fast sites. While "make your site faster" is a simple mantra, the actual steps to achieve this can be daunting. Fortunately, we know where to start: JavaScript. JavaScript consumes more CPU than loading, layout, and rendering combined. Byte-for-byte, JavaScript inflicts more delays on sites than any other resource, and yet the amount of JavaScript on sites continues to grow.
In this session you'll learn the latest techniques for measuring and improving the impact JavaScript on your site, including: using the User Timing Spec and Long Tasks API to track the CPU cost of JavaScript for real users, moving expensive JavaScript off the main thread, using code coverage tools to reduce your JavaScript, and understanding why defer is probably a better technique than async for loading JavaScript.
As browsers explode with new capabilities and migrate onto devices users can be left wondering, “what’s taking so long?” Learn how HTML, CSS, JavaScript, and the web itself conspire against a fast-running application and simple tips to create a snappy interface that delight users instead of frustrating them.
Web Performance & You - HighEdWeb Arkansas VersionDave Olsen
Today, a web page can be delivered to a desktop computer, a television, or a handheld device like a tablet or a phone. While a technique like responsive design helps ensure that our web sites look good across that spectrum of screen sizes we may forget our web sites should also be able to perform equally well across that same spectrum. While more and more of our users are shifting their Internet usage to these more varied platforms and connection speeds our development practices might not be keeping up.In this session we’ll review why optimizing web performance should be an important step in the development of responsive websites. We’ll look at the tools that can help you understand and measure the performance of those sites as well as discuss front-end and server-side techniques that can be used to help you improve their performance. Finally, since the best way to test your site is to have real devices in hand, we’ll share “lessons learned” so you can set-up your own device lab similar to what we have at West Virginia University.This presentation builds upon Dave’s “Optimization for Mobile” chapter in Smashing Magazine’s “The Mobile Book.”
Happy Browser, Happy User! NY Web Performance Meetup 9/20/19Katie Sylor-Miller
xPerformance 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.

So you want to build a mobile app - HTML5 vs. Native @ the Boston Mobile Expe...Yottaa
Building a mobile app - depending upon who you speak with it's a quick way to make a ton of cash (SnapChat), a sign of maturity for a SaaS startup that offers advantages over a desktop solution (ifttt), or the only way your company chooses to do business (WhatsApp). If you get it right...
Today's mobile app developers have to make some difficult choices in their implementations, and a lack of history to provide clear direction doesn't help. In this meetup we'll look at Responsive, Adaptive and Native app development alternatives and how your choice can impact day-to-day necessities like testing and troubleshooting. This will be slightly more technical than our last meetup as we will examine implementations and optimization techniques using mobile applications in the wild.
I was invited by the Hatchery+ to give a presentation and workshop on building products - a brief overview on modern web apps, tech stacks, languages, frameworks, services, APIs and more.
When creating mobile apps, solid performance is now mandatory. We'll expose the patterns and anti-patterns that will impact this critical trait of your apps, while building a performant mobile app live.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

116. The 14K limit
RTT
• TCP slow start
• Initial congestion window: ~14.6Kb (compressed)
• > 14Kb will create another roundtrip
117. We need to separate
ABOVE THE FOLD (ATF)
content
118. ATF in 1s = 1 RTT ~ < 14Kb
HTML + CSS + JavaScript
Images?
ATF
119. Avoid JavaScript frameworks
ATF
• Embrace Vanilla JS
• If you really need them, load them after ATF
• Think on alternatives or partial frameworks
120. Careful with Data URI in CSS
ATF
• Images are non-blocking by default
• Using Data URI in CSS creates blocking images
• Use them only on non-ATF external CSS
130. Responsive Web Design
• Using same URL for mobile/desktop still a good a idea
• Mix it with RESS / adaptive web design
• Load media queries CSS async
• Use server-side libraries
• WURFL or DeviceAtlas
131. After ATF is ready
• Load rest of your content
• Gain experience while rendering ATF:
current performance, screen density, bandwidth
• Make decisions: HD/SD
137. 4- responsiveness & experience
- consistent frame rate
- immediate feedback
- scrolling
- your new enemy
138. consistent fps
Keep framerate high and consistent
• Main UI thread as free as possible
• Avoid repainting (software bitmap calculations)
139. JavaScript
framerate
• Avoid DOM manipulations inside loops/scroll
var e = document.querySelector("#test");
for (var i=0; i<100; i++) {
// change e attributes
});
JAVASCRIPT
165. final thoughts
- measure and profile on the real world
- don’t redirect, reduce requests
- atf content in 1s, defer the rest
- be simple, be aggressive
