(A presentation given at Velocity Conference, London 2012)
Mobile Optimization is complicated, and there’s no single silver bullet. Many different bottlenecks take their toll along the way, and while some have a huge impact, others still add up. In this presentation, we’ll take a website and optimize it step by step. In each step we’ll touch on a problem, discuss how to solve it – perhaps in multiple ways – and show the effect of the solution. In the process, we’ll also touch on topics such as measuring mobile performance, differences between browsers, and which pitfalls are common
Aptimize Website Accelerator is a software that speeds up SharePoint websites by 33-75% by reducing round trips between the server and browser. It uses patent pending techniques to optimize pages for performance before sending them to the browser. No additional hardware, code changes, or costs are required. It merges files, removes unused code and images, compresses files, and caches content to improve page load times without any developer work.
Doug Sillars presented four simple optimizations for delivering fast and beautiful images and video on mobile: 1) reduce image quality, 2) use optimized formats like WebP and SVG, 3) size images appropriately, and 4) lazy load images below the fold. He demonstrated how these techniques can significantly reduce page load times and data usage. Sillars also discussed best practices for video delivery and alternatives to animated GIFs that can reduce file sizes substantially. Throughout, he provided real-world examples and tools to help optimize multimedia content for mobile performance.
The document discusses how Akamai's Intelligent Internet Platform addresses challenges posed by increasingly sophisticated websites and rising consumer expectations for faster load times and richer content. It does this through a global network of servers that optimize routing, cache content closer to users, compress data and prefetch resources to accelerate page loads. Case studies show how Akamai has helped customers like Best Buy and Urban Outfitters improve performance, scale to handle traffic spikes and reduce infrastructure costs.
Cloud Performance: Guide to Tackling Cloud Latency [Cloud Connect - Chicago 2...
Performance matters. And in the cloud, performance matters more than ever—layers of complexity and third-party, shared environments separate users from applications. Services are elastic, which means you can have any SLA you want, as long as you're willing to design it yourself. And you can have a fast application, too—if you're willing to deal with the bill at the end of the month.
So how should you think about cloud performance? In this in-depth workshop on the performance of cloud computing, three cloud computing and Internet performance experts—Steve Riley (Riverbed, Amazon), Hooman Beheshti (Strangeloop, Radware) and Alistair Croll (Coradiant, CloudOps)—take you on a tour of the challenges on-demand computing poses to reliable, fast user experiences.
What you'll learn:
- The new models of delay, capacity, and uptime that on-demand computing requires
- What and how to measure when it comes to performance, and how to think about metrics
- Where delay happens across the cloud environment
- How shared computing and back-end contention affect user experience
- What the WAN and the Application Delivery Network mean in a cloudy compute model
- How to spread load and optimize application front-ends to speed up applications
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.
The document discusses using database permissions to manage application authorization. It describes a basic tiered application architecture with a web server, application, and database layers. Implementing permissions at the database layer avoids limitations of application-managed permissions but requires some additional work. The document outlines approaches for implementing database roles and permissions, integrating them with an application via stored procedures, and handling authentication in the application framework. Both advantages and disadvantages of the database permissions approach are presented, including consistency across layers but lack of direct row-level controls.
This document discusses optimizing mobile application performance through testing. It begins by explaining that performance is a human perception, with delays of 100ms feeling instantaneous, 1s still allowing for an uninterrupted train of thought, and 10s being the limit to maintain focus. It then discusses benchmarking applications to understand current performance, identifying fixes, optimizing through things like image size and format, caching, and lazy loading. The overall message is that thorough testing across devices and networks is needed to optimize mobile applications for speed.

Specific techniques covered include profiling network conditions, testing on low-end devices, setting speed goals, optimizing JSON responses, image sizes/formats/quality, and caching. The overall message is that thorough testing across devices and networks is needed to optimize mobile application speed for the best user experience.
The document discusses the rise of Comet technology, which allows for highly interactive websites by enabling real-time updates from servers to browsers without polling. It covers the technical challenges of implementing Comet, different connection options like long polling and websockets, API styles including pub/sub and data sync approaches, and considerations around inboard vs outboard Comet architectures. The goal of Comet is to make the web more like a persistent connection instead of a traditional request-response model.
This document discusses mobile application performance testing. It begins by explaining how fast is perceived by humans, with 100ms seen as instant, 1s as an acceptable delay, and 10s as the limit to maintain focus. It then discusses various performance studies showing user frustration and abandonment rates related to load speeds. The document goes on to describe benchmarking applications, identifying fixes, optimizing through various techniques, and retesting. Specific areas covered in more depth include optimizing images through size, quality, format, caching and lazy loading. Other topics include content delivery networks, animating GIFs, and network information.
In last 4 years, two new image formats were added to the web technology arsenal -- WebP & JPEG XR. These image formats are far superior to their predecessors, but unfortunately are only supported by very specific browsers, and aren't always easy to generate. Akamai has recently added support for these image formats, and learned a lot in the process. In this short talk, Ido will explain more about these formats and share some of our experience working with them.
This document provides tips for optimizing images for fast loading on mobile websites. It discusses how image size, quality, format, caching, and lazy loading can significantly impact performance. Specific techniques recommended include resizing images to appropriate screen sizes, using formats like WebP and SVG that compress well, lazy loading images below the fold, and adding responsive breakpoints to serve optimized images for different devices. Benchmarking tools are suggested for testing image performance in various scenarios. The overall message is that with the right optimizations, images can load quickly without sacrificing quality.
The document provides an overview of options for accessing data stored in Lotus Notes databases from other systems. It discusses generating feeds using the ReadViewEntries API to output data in XML or JSON format, as well as creating calendar feeds using the iCalendar format.

The document discusses Android media player development. It covers characteristics of video streams like frame rate, interlacing vs progressive, aspect ratio, color depth and video compression methods. It then discusses the Android media player API, limitations and advanced development using FFmpeg library. Key points covered include supported video formats, media player class methods, state changes and errors that can occur. Customizing the player is described as providing benefits like security and real-time ads but also drawbacks like increased errors.
This document discusses 3D video encoding and delivery standards for Android devices. It covers 3D video formats like side-by-side and top-bottom, support in H.264 profiles and HDMI standards, and how to configure the encoder on TI and Qualcomm processors to add 3D signaling information to the encoded video stream. By inserting frame packing and stereo metadata, devices can automatically detect 3D content and display it correctly without user intervention.
The document discusses the four types of sentences: interrogative sentences which ask questions and end with question marks, declarative sentences which make statements and usually end with periods, imperative sentences which give commands or directions and can end with periods or exclamation marks, and exclamatory sentences which show strong emotion, begin with "what" or "how", and end with exclamation marks. Examples are provided for each type of sentence.
The document discusses varying sentence structure to make writing more interesting. It provides examples of simple sentences with one clause, compound sentences with two independent clauses joined with coordinating conjunctions or semicolons, and complex sentences with one independent and one dependent clause. The second paragraph is more effective because it uses a variety of sentence structures including compound and complex sentences rather than just simple sentences.
This document provides information on how to vary sentence structure to make writing more interesting. It discusses using simple, compound, complex, and compound-complex sentences. Simple sentences contain one independent clause, while compound sentences contain two independent clauses joined with a conjunction. Complex sentences have one independent clause and one dependent clause. Compound-complex sentences contain two or more independent clauses and one or more dependent clauses. The document provides examples of each sentence type and guidelines for using commas with different clauses.
The document discusses the four types of sentences: declarative, exclamatory, interrogative, and imperative. A declarative sentence makes a statement, an exclamatory sentence expresses strong emotions and ends with an exclamation point, an interrogative sentence asks a question and ends with a question mark, and an imperative sentence gives a command. It provides examples of each sentence type and has the reader identify the type of four example sentences. In conclusion, it reviews the four sentence types and explains the difference between a sentence and a fragment.
Performance Implications of Mobile Design (Perf Audience Edition)
(This version of the presentation is oriented at a web performance audience, and includes some mobile design 101 content)
Mobile Web Design is complicated, and several design paradigms have been created to help deal with the challenges the mobile landscape creates.
Amongst other implications, each paradigm also carries its own performance pitfalls, which can turn a well designed site into a horribly slow user experience.
This presentation covers the top design paradigms - Dedicated Websites (mdot) and Responsive Web Design, gives some background on each, and digs into the performance do's and don'ts for your design of choice.
This document discusses strategies for improving the performance of single page applications (SPAs). It begins by introducing common SPA frameworks and trends. It then discusses challenges like framework overhead and constant reinstallation that can degrade performance. Solutions presented include light first visits using skeleton pages, server-side rendering, virtual DOM libraries, JavaScript packaging, resource deferral, caching optimizations, and monitoring SPA-specific metrics. The document emphasizes the importance of choosing the right framework, designing for performance, and testing SPAs using modern techniques.
Making Single Page (SPA) Faster was a presentation done at Velocity NY 2016
It covers 3 main points:
- selecting the right framework (performance oriented)
- best practices and optimizations
- monitoring

The document discusses front end optimization (FEO) which refers to techniques for improving the performance of how web pages load in browsers. It focuses on reducing the number of round trips, bytes transferred, and improving caching and page rendering. The document outlines specific FEO techniques companies can implement manually but notes it requires significant resources. It then discusses the emerging FEO automation industry and challenges around automating the process while avoiding breaking pages or optimization issues.
Thomas Higdon from Akamai Technologies discusses how they use OpenNebula to clone virtual machine instances of Akamai's global content delivery network. This allows them to more quickly provision development and testing environments that mimic Akamai's production instances. OpenNebula manages the virtual machines and resources while an Akamai instance service exposes machine types and services. Teams can then use the same instance across development, QA, and testing stages to improve process unification.

Thomas Higdon from Akamai Technologies discusses how they use OpenNebula to clone virtual machine instances of Akamai's global content delivery network. This allows them to more quickly provision development and testing environments that mimic Akamai's production instances. OpenNebula manages the virtual machines and resources while an Akamai instance service exposes specific machine types and services. When changes need testing, they can clone an existing instance to a new environment rather than rebuilding it from scratch.
The document discusses responsive web design and how Akamai solutions can help address common problems with RWD. It describes strategies for RWD like adaptive delivery and responsive client-side design. Common issues with RWD include over-downloading content and image-related problems. Akamai solutions like adaptive images, responsive images, Edge Server Includes, and responsive server-side design can help optimize content delivery for different devices and networks. These solutions can improve page load times and the user experience compared to traditional RWD approaches.
The document discusses how Akamai's Dynamic Site Accelerator (DSA) can help websites address performance, scalability, security, and availability issues. DSA leverages Akamai's global edge network to speed page loading, optimize caching, improve TCP performance, and offload website infrastructure. It provides an example of how DSA helped Cathay Pacific boost online bookings and reduce infrastructure costs. In summary, DSA leverages Akamai's edge network to improve website performance, scalability, and availability while reducing infrastructure needs and costs.
The document discusses how Akamai's responsive web design (RWD) and image optimization solutions can improve website performance for desktop and mobile users. It shows that Akamai's Ion Standard solution improved page load times by 92-99% and that Ion Premier improved load times by 125-235%. Pairing Ion Premier with additional image optimization and design tools improved load times even further by 272-400%.
This document discusses Akamai's content delivery network (CDN) and its peering relationships. It provides an overview of Akamai, describing its intelligent platform of over 150,000 servers worldwide. It explains how Akamai uses mapping rather than BGP routing to direct users to optimal edge servers. The document also discusses why Akamai peers directly with internet service providers - to improve performance for users, reduce costs, and increase reliability during high traffic events. Finally, it notes that peering benefits internet service providers too by enhancing content delivery and reducing transit fees.

Learn how to setup Apache for high performance sites and leverage many of its available modules to deliver a faster web experience for your users. Discover how Apache can max out a 1 Gbps NIC and how to serve over 140,000 pages per minute with a small Apache cluster. This presentation was given by Spark::red's founding partner Devon Hillard in March 2012 at the Boston Web Performance Meetup.
Being able to review and assess configurations is key in improving efficiency and performance for our websites. During this session, we will discuss and demonstrate how to review your Akamai configurations in order to move towards updated and efficient methods. In order to improve all aspects of websites, we will cover areas including images, protocols, DNS, caching, and more. Not only will we essentially teach you how to perform mini configuration assessments, but we will also walk through several basic steps using industry tools and Akamai solutions that can help address performance pitfalls within a website today. These tools will range anywhere from using WebPageTest, PageSpeed, to more Akamai focused areas such as Log Analysis, Portal Reports and other Akamai solutions.
The document discusses website performance and optimization. It notes that nearly half of users expect a site to load within 2 seconds and will abandon a site taking longer than 3 seconds. Common issues causing poor performance are bloated templates, unnecessary code, and too many HTTP requests. Suggested optimizations include minimizing assets, prioritizing visible content, image optimization, caching, compression, and lazy loading. Case studies show significant speed improvements after implementing optimizations. Metrics like Speed Index measure how quickly visible content displays to influence perceived performance.
This document discusses web performance optimization and provides tips to improve performance. It emphasizes that performance is important for user experience, search engine optimization, conversion rates, and costs. It outlines common causes of performance issues like round-trip times, payload sizes, browser rendering delays, and inefficient JavaScript. Specific recommendations are given to optimize images, stylesheets, scripts, and browser rendering through techniques like compression, caching, deferred loading, and efficient coding practices. A variety of tools for measuring and improving performance are also listed.
Serverless means handing off server management to the cloud platforms – along with their security risks. With the “pros” ensuring our servers are patched, what’s left for application owners to protect? As it turns out, quite a lot.
This talk discusses the aspects of security serverless doesn’t solve, the problems it could make worse, and the tools and practices you can use to keep yourself safe.
Required audience experience
Basic knowledge of how FaaS and Serverless works
Objective of the talk
As many companies explore the world of serverless, it’s important they understand the aspects of security this new world helps them with, and the ones they need to care more about. This talk will provide a framework to understand how to prioritise and approach security for Serverless apps.
Guy Podjarny breaks into a vulnerable serverless application and exploits multiple weaknesses, helping better understand some of the mistakes people make, their implications, and how to avoid them.

Some of the very things that make JavaScript awesome can also leave it exposed. Guy Podjarny and Danny Grander walk through some sample security flaws unique to Node’s async nature and surrounding ecosystem (or especially relevant to it)—e.g., memory leaks via the buffer object, ReDoS and other algorithmic DoS attacks (which impact Node due to its single-threaded nature), and timing attacks leveraging the EventLoop—and show how these could occur in your own code or in npm dependencies.
npm packages are awesome, but also introduce risk.
This presentation explains how packages may introduce known vulnerabilities into your application, explains their impact, and most importantly, shows how to protect yourself.
The few slides were complemented by running several vulnerability exploits against the vulnerable demo app Goof from here: https://github.com/Snyk/goof
Stranger Danger: Securing Third Party Components (Tech2020)
Building software today involves more assembly than actual coding. Much of our code is in fact pulled in open source packages, and the applications heavily rely on surrounding third party binaries. These third parties make us more productive - but they also introduce an enormous risk. Each third party component is a potential source of vulnerabilities or malicious code, each third party service a potential door into our system.
This talk contains more information about this risk, create a framework for digesting and tackling it, and lists a myriad of tools that can help.
High Performance Images: Beautiful Shouldn't Mean Slow (Velocity EU 2015)
The web is becoming increasingly image rich. Between high-resolution mobile screens, Pinterest-style design, and big background graphics, the average image payload has more than doubled in the last three years. While visually appealing, these images carry a substantial performance cost, and — if not optimized correctly — can make a web experience slow and painful, no matter how beautiful it is.
In this tutorial we’ll discuss ways that let you provide the eye-pleasing experience you want without sacrificing your site’s performance.You’ll learn about the three primary aspects of image optimization:
- Image compression: how to best encode your images, delivering the same picture with the fewest bytes
- Image loading: once your files are as small as they can be, we’ll cover the best ways to make them show up quickly in the browser
- Operationalizing image optimization: different tools and techniques for integrating image optimization on your site

HTTPS: What, Why and How (SmashingConf Freiburg, Sep 2015)
When users use our sites, they put their faith in us. They trust we will keep their information from reaching others, believe we provided the information they see, and allow us to run (web) code on their devices. Using HTTPS to secure our conversations is a key part of maintaining this trust.
If that’s not motivation enough, the web’s giants are actively promoting HTTPS, requiring it for features such as HTTP2 & ServiceWorker, using it for search engine ranking and more. To make the most of the web, you need to use HTTPS.
This deck reviews what HTTPS is, discusses why you should prioritize using it, and cover some of the easiest (and most cost effective) steps to get started using HTTPS

The document discusses the four types of sentences: interrogative sentences which ask questions and end with question marks, declarative sentences which make statements and usually end with periods, imperative sentences which give commands or directions and can end with periods or exclamation marks, and exclamatory sentences which show strong emotion, begin with "what" or "how", and end with exclamation marks. Examples are provided for each type of sentence.
The document discusses varying sentence structure to make writing more interesting. It provides examples of simple sentences with one clause, compound sentences with two independent clauses joined with coordinating conjunctions or semicolons, and complex sentences with one independent and one dependent clause. The second paragraph is more effective because it uses a variety of sentence structures including compound and complex sentences rather than just simple sentences.
This document provides information on how to vary sentence structure to make writing more interesting. It discusses using simple, compound, complex, and compound-complex sentences. Simple sentences contain one independent clause, while compound sentences contain two independent clauses joined with a conjunction. Complex sentences have one independent clause and one dependent clause. Compound-complex sentences contain two or more independent clauses and one or more dependent clauses. The document provides examples of each sentence type and guidelines for using commas with different clauses.
The document discusses the four types of sentences: declarative, exclamatory, interrogative, and imperative. A declarative sentence makes a statement, an exclamatory sentence expresses strong emotions and ends with an exclamation point, an interrogative sentence asks a question and ends with a question mark, and an imperative sentence gives a command. It provides examples of each sentence type and has the reader identify the type of four example sentences. In conclusion, it reviews the four sentence types and explains the difference between a sentence and a fragment.
Performance Implications of Mobile Design (Perf Audience Edition)Guy Podjarny
(This version of the presentation is oriented at a web performance audience, and includes some mobile design 101 content)
Mobile Web Design is complicated, and several design paradigms have been created to help deal with the challenges the mobile landscape creates.
Amongst other implications, each paradigm also carries its own performance pitfalls, which can turn a well designed site into a horribly slow user experience.
This presentation covers the top design paradigms - Dedicated Websites (mdot) and Responsive Web Design, gives some background on each, and digs into the performance do's and don'ts for your design of choice.

It focuses on reducing the number of round trips, bytes transferred, and improving caching and page rendering. The document outlines specific FEO techniques companies can implement manually but notes it requires significant resources. It then discusses the emerging FEO automation industry and challenges around automating the process while avoiding breaking pages or optimization issues.
Thomas Higdon from Akamai Technologies discusses how they use OpenNebula to clone virtual machine instances of Akamai's global content delivery network. This allows them to more quickly provision development and testing environments that mimic Akamai's production instances. OpenNebula manages the virtual machines and resources while an Akamai instance service exposes machine types and services. Teams can then use the same instance across development, QA, and testing stages to improve process unification.
OpenNebulaConf 2013 - Keynote: Clone your Network with OpenNebula by Thomas H...OpenNebula Project
Thomas Higdon from Akamai Technologies discusses how they use OpenNebula to clone virtual machine instances of Akamai's global content delivery network. This allows them to more quickly provision development and testing environments that mimic Akamai's production instances. OpenNebula manages the virtual machines and resources while an Akamai instance service exposes specific machine types and services. When changes need testing, they can clone an existing instance to a new environment rather than rebuilding it from scratch.
The document discusses responsive web design and how Akamai solutions can help address common problems with RWD. It describes strategies for RWD like adaptive delivery and responsive client-side design. Common issues with RWD include over-downloading content and image-related problems. Akamai solutions like adaptive images, responsive images, Edge Server Includes, and responsive server-side design can help optimize content delivery for different devices and networks. These solutions can improve page load times and the user experience compared to traditional RWD approaches.

Serverless Security: What's Left To ProtectGuy Podjarny
Serverless means handing off server management to the cloud platforms – along with their security risks. With the “pros” ensuring our servers are patched, what’s left for application owners to protect? As it turns out, quite a lot.
This talk discusses the aspects of security serverless doesn’t solve, the problems it could make worse, and the tools and practices you can use to keep yourself safe.
Required audience experience
Basic knowledge of how FaaS and Serverless works
Objective of the talk
As many companies explore the world of serverless, it’s important they understand the aspects of security this new world helps them with, and the ones they need to care more about. This talk will provide a framework to understand how to prioritise and approach security for Serverless apps.
Guy Podjarny breaks into a vulnerable serverless application and exploits multiple weaknesses, helping better understand some of the mistakes people make, their implications, and how to avoid them.

Some of the very things that make JavaScript awesome can also leave it exposed. Guy Podjarny and Danny Grander walk through some sample security flaws unique to Node’s async nature and surrounding ecosystem (or especially relevant to it)—e.g., memory leaks via the buffer object, ReDoS and other algorithmic DoS attacks (which impact Node due to its single-threaded nature), and timing attacks leveraging the EventLoop—and show how these could occur in your own code or in npm dependencies.
npm packages are awesome, but also introduce risk.
This presentation explains how packages may introduce known vulnerabilities into your application, explains their impact, and most importantly, shows how to protect yourself.
The few slides were complemented by running several vulnerability exploits against the vulnerable demo app Goof from here: https://github.com/Snyk/goof
Stranger Danger: Securing Third Party Components (Tech2020)Guy Podjarny
Building software today involves more assembly than actual coding. Much of our code is in fact pulled in open source packages, and the applications heavily rely on surrounding third party binaries. These third parties make us more productive - but they also introduce an enormous risk. Each third party component is a potential source of vulnerabilities or malicious code, each third party service a potential door into our system.
This talk contains more information about this risk, create a framework for digesting and tackling it, and lists a myriad of tools that can help.
High Performance Images: Beautiful Shouldn't Mean Slow (Velocity EU 2015)Guy Podjarny
The web is becoming increasingly image rich. Between high-resolution mobile screens, Pinterest-style design, and big background graphics, the average image payload has more than doubled in the last three years. While visually appealing, these images carry a substantial performance cost, and — if not optimized correctly — can make a web experience slow and painful, no matter how beautiful it is.
In this tutorial we’ll discuss ways that let you provide the eye-pleasing experience you want without sacrificing your site’s performance.You’ll learn about the three primary aspects of image optimization:
- Image compression: how to best encode your images, delivering the same picture with the fewest bytes
- Image loading: once your files are as small as they can be, we’ll cover the best ways to make them show up quickly in the browser
- Operationalizing image optimization: different tools and techniques for integrating image optimization on your site

HTTPS: What, Why and How (SmashingConf Freiburg, Sep 2015)Guy Podjarny
When users use our sites, they put their faith in us. They trust we will keep their information from reaching others, believe we provided the information they see, and allow us to run (web) code on their devices. Using HTTPS to secure our conversations is a key part of maintaining this trust.
If that’s not motivation enough, the web’s giants are actively promoting HTTPS, requiring it for features such as HTTP2 & ServiceWorker, using it for search engine ranking and more. To make the most of the web, you need to use HTTPS.
This deck reviews what HTTPS is, discusses why you should prioritize using it, and cover some of the easiest (and most cost effective) steps to get started using HTTPS

Slides from my Web Directions South 2014 Talk.
Abstract:
Responsive Web Design (RWD) is upon us, and it seems like every website has either gone responsive or planning to do so. And in this rush to implement – performance is left behind…
Last November (2013), I ran a test identifying the responsive websites amongst the top 10,000 sites, and inspected their performance traits. The results were depressing, showing many sites have gone responsive, and hardly any tackled performance.
In this talk, we’ll track the progress (or lack there of) we made as an industry. We’ll look at the results of a new test, tracking our progress in adopting RWD and – more importantly – in addressing its performance implications. We’ll share high level stats, highlight key trends, drill into representative examples, and come away with a better understanding of what we should be doing better, both on our own sites and as an industry
Third Party Performance (Velocity, 2014)Guy Podjarny
Third party components are a part of any modern site: JS libs, analytics, trackers, share buttons, ads. Many components, each adding its performance cost, cause render delays or can effectively take your site down. This isn’t your code nor your servers, so what can you do about it?
This presentation will answer this question with strategies and tactics for keeping 3rd parties from taking you down.
This talk was given at Velocity Santa Clara, 2014: The presentation from Velocity Santa Clara, 2014 (http://velocityconf.com/velocity2014/public/schedule/detail/35448).
This document discusses how a URL is no longer sufficient for content delivery given modern dynamic web pages. It proposes implementing "rules driven delivery" where delivery definitions are structured as reusable, hierarchical rules that define criteria for when to apply delivery behaviors. These rules would be pushed to CDN edges to enable offloading and improve performance over simply relying on URLs and caching. Examples of rules provided include redirecting mobile users, image format negotiation based on Accept headers, and granular caching based on request header values. The goal is more flexible content delivery and caching optimized for a wide variety of dynamic web page scenarios.
Responsive In The Wild (SmashingConf, 2014)Guy Podjarny
Awareness to Responsive Web Design has grown substantially over the last few years, and practically any major organization has some RWD project in their Mobile Strategy decks. However, are we just talking about it, or actually doing it?
I ran a mass test to identify the responsive websites amongst the top 100,000 websites in the world. Eventually, we'll be able to rerun this test to track RWD adoption over time, but for now we can use it to see how RWD sites compare to each other and to non-RWD sites.
This short presentation, given over beers at the awesome SmashingConf, shares some such insights.

Putting Your Images on a Diet (SmashingConf, 2014)Guy Podjarny
Images are quickly becoming one of the most critical factors for web performance. On one hand, users are demanding more visual websites, driving an increase in the number of images on a page and making background images cool again. On the other hand, technology trends such as Retina displays and RWD are making it much harder to choose the right image to download at any given time, avoiding the download of excess bytes.
In this talk, I go over what you can do to maximize the impact of every image byte. I explain the concept of Image Compression, understand how it applies to different image formats, and show the tools and techniques you should use to communicate the best visuals with the fewest bytes. Lastly, I show how to combine image compression and Retina displays, and discuss some newer image formats and how you can take advantage of them today
Third party-performance (Airbnb Nerds, Nov 2013)Guy Podjarny
Almost every site on the internet today serves 3rd-party assets and code - jQuery, analytics, trackers, share buttons, ads - from both their own servers and others - cloud providers, dedicated hardware, CDNs, google hosting. These third parties can have a significant effect on performance, delaying the load event, deferring actions, and being a single point of failure beyond your control. This deck discusses techniques and strategies for working with 3rd parties within these limitations, and shares some relevant community work.
Third parties are a part of our reality, and offer great business value - but also present some very real performance concerns.
This deck attempts to define and offer strategies, along with some practical tips, on how to deal with this problem.
Images seem simple - they're static, independent from each other, and don't mess up the DOM. However, images make up 60%-70% of page bytes, and their visual nature makes them critical for user experience. Investing in Image Optimization is a highly worthwhile investment.
This presentation covers 4 aspects of Image Optimization:
- Optimizing Image formats (including background on GIF, PNG, JPEG, WebP, JPEG XR and more)
- Optimizing image delivery
- Optimizing image loading in the page
- Responsive Images - optimizing images for mobile screens
The Mobile Web is a complicated beast, making Mobile Web Performance a tough problem to tackle. Is an iPad on WiFi a part of the Mobile Web? How about a laptop with a 3G stick?
This presentation tries to split the Mobile Web into three categories, to make it more manageable: Network, Software & Hardware. For each, it reviews the performance challenges this category entails, and offers possible solutions to those challenges.

Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
