PayPal as a Service

Moved away from
good old java

Changing the way we work
• CSS, HTML and even JS in Java
• Later replaced by JSP for templating
• Open Source Stack
• Bootstrap for frontend
• JavaScript templating via Dust
• Project Delorean: V8 in PayPal’s C++ stack
• Rhino: JS for PayPal’s Java stack

Lusca
Makara
AdaroKappa

Results
• Team sizes decreased
• Doubled requests per second
• 35% decrease in average response time
• Lines of code shrunk by factor 3 to 5
• Increased development pace
• Full stack JS investment

Thank you!
for not killing me

Docker is currently one of the most popular Go projects. After a (quick) Docker intro, we will discuss why we picked Go, and how it turned out for us. We tried to list all the drawbacks and minor inconveniences that we met while developing Docker; not to complain about Go, but to give the audience an idea of what to expect. Depending on your project, those drawbacks could be minor inconveniences or showstoppers; we thought you would want to know about them to help you to make the right choice!

The “People You May Know” (PYMK) recommendation service helps LinkedIn’s members identify other members that they might want to connect to and is the major driver for growing LinkedIn's social network. The principal challenge in developing a service like PYMK is dealing with the sheer scale of computation needed to make precise recommendations with a high recall. PYMK service at LinkedIn has been operational for over a decade, during which it has evolved from an Oracle-backed system that took weeks to compute recommendations to a Hadoop backed system that took a few days to compute recommendations to its most modern embodiment where it can compute recommendations in near real time. This talk will present the evolution of PYMK to its current architecture. We will focus on various systems we built along the way, with an emphasis on systems we built for our most recent architecture, namely Gaia, our real-time graph computing capability, and Venice our online feature store with scoring capability, and how we integrate these individual systems to generate recommendations in a timely and agile manner, while still being cost-efficient. We will briefly talk about the lessons learned about scalability limits of our past and current design choices and how we plan to tackle the scalability challenges for the next phase of growth. https://qcon.ai/qconai2019/presentation/people-you-may-know-fast-recommendations-over-massive-data

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

Dubai, known for its towering skyscrapers, luxurious lifestyle, and relentless pursuit of innovation, often finds itself in the global spotlight. However, amidst the glitz and glamour, the emirate faces its own set of challenges, including the occasional threat of flooding. In recent years, Dubai has experienced sporadic but significant floods, disrupting normalcy and posing unique challenges to its infrastructure. Among the critical nodes in this bustling metropolis is the Dubai International Airport, a vital hub connecting the world. This article delves into the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

Following the popularity of "Cloud Revolution: Exploring the New Wave of Serverless Spatial Data," we're thrilled to announce this much-anticipated encore webinar. In this sequel, we'll dive deeper into the Cloud-Native realm by uncovering practical applications and FME support for these new formats, including COGs, COPC, FlatGeoBuf, GeoParquet, STAC, and ZARR. Building on the foundation laid by industry leaders Michelle Roby of Radiant Earth and Chris Holmes of Planet in the first webinar, this second part offers an in-depth look at the real-world application and behind-the-scenes dynamics of these cutting-edge formats. We will spotlight specific use-cases and workflows, showcasing their efficiency and relevance in practical scenarios. Discover the vast possibilities each format holds, highlighted through detailed discussions and demonstrations. Our expert speakers will dissect the key aspects and provide critical takeaways for effective use, ensuring attendees leave with a thorough understanding of how to apply these formats in their own projects. Elevate your understanding of how FME supports these cutting-edge technologies, enhancing your ability to manage, share, and analyze spatial data. Whether you're building on knowledge from our initial session or are new to the serverless spatial data landscape, this webinar is your gateway to mastering cloud-native formats in your workflows.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system. About authorWith two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.
