Tuning the JVM GC to reduce garbage collection time will speed up application performance. If you agree with that statement then I encourage you to listen to this episode where I have Stefano Doni, CTO at Akamas, walk us through 4 Java Tuning Facts & Myths. He is going into details why even in 2021 with great improvements in the JVM it is still important to optimize the JVM specific to the environment, workload and application behavior. If you want some visuals try to catch his presentation from this years Performance Summit called “How AI optimization will debunk 4 long standing Java tuning myths”

To follow up with Stefano check out their resources such as their tutorials on explore.akamas.io, check out their blog posts or videos on their new website akamas.io or follow them on twitter @akamaslabs

Understanding the secret behind the turbo button on his first 486 PC motivated our guest to study computer science. That decision started a journey making him constantly learn new technology ranging from coding languages, operational tasks as well as a focusing on improving developer experiences and boosting developer productivity

Listen in and hear from Michael Friedrich (@dnsmichi), The Ops in Dev Evangelist at GitLab, on why it is important to enable developers to design and develop code that makes it easier for DevOps and SREs to operate and automate. “The biggest challenge is code that breaks production but where there is no clear evidence for DevOps & SREs about the root cause”

“Because 9 out of 10 load testing projects fail due to ignorance and outdated thinking about load testing!”. That was the answer Leandro Melendez, aka Señor Performo, gave us when asking him why the world needs yet another book about load testing.

In too many projects Leandro has to remind and educate decision makers and practitioner’s about load testing best practices, how to ask the right questions and how to approach a project from start to finish. His book “The hitchhiking guide to load testing projects” is a fun and edu-taining read for people that are new to the trade as well as seasoned performance engineers.

For more content from Senor Performo check out his PerfBytes Espanol Podcast, his Spanish YouTube channel and all the performance engineering presentations he has been given over the years.

Building products that people want to use and activating users to try out new capabilities has to be the ultimate goal of every product manager. User and usage data is the enabler to make the right decisions. But data doesn’t come for free – and making the right decisions is something that data alone doesn’t guarantee

Listen in and learn from Manav Chugh, product enthusiast, medium blogger and organizer of ProductTank Linz, what inspired him to choose the path from Zero to Data-Driven Product Manager. In our conversation we cover how to capture what data, the importance of data privacy, what we can learn from companies that do data-driven design well and why he loves organizations such as www.ecosia.org.

Like many frontend developers, Sergey Chernyshev was inspired in the late 2000 by Steve Souders to contribute to and grow the web performance community. Not only did he launch the Meed4SPEEDs as part of the New York Web Performance Meetup. He also worked for meetup.com helping them to improve web performance and user experience. Over the past years Sergey contributed to many projects such as WebPageTest.org, UX Capture Library, Jamstack and more.

Tune in to this episode, learn what has and what hasn’t changed in the quest for better user experience. Get a quick start on Core Web Vitals and current challenges. Most important: get inspired to contribute back to this community.

In his SLOConf talk Production load testing as a guardrail for SLOs and in his blog Production Load Testing, Hassy Veldstra, founder of artillery.io makes the case for load testing in production. It helped him in various organizations to establish SLOs (Service Level Objectives) and change the way engineers think about performance. He got inspired by Building Evolutionary Architectures which introduces the concept of performance as a fitness function.

Tune in into our conversation, hear our arguments pro and contra load testing in the various environments and learn why in the end we agreed on the fact that SLOs – while nothing really new – are a great chance to re-define performance engineering.

How do you convince an organization that just went through a 2 year DevOps transformation to continue the journey by applying SRE practices? What is SRE anyway? What are good SLOs? And how do you get development teams to take responsibility for their code in production?

Bart Enkelaar, Lead Site Reliability Engineer at bol.com, not only got their organization to apply SRE practices, define good SLOs and got dev teams to rotate on-call duties. He also followed the advice of Margaret, Chief Platform Officer, to bring his personal passion to the job. This led to inspiring and educating the community about SRE and SLO through music. To see what I mean check out Barts The Game of SLOs – a three part reliability musical from SLOConf or his funny tech conversations at Friendly Tech Chats.

While some think about the late Austrian musician, Dan POP and the CNCF community thinks about modern security when it comes to Falco.

Listen in and hear directly from Dan (@danpopnyc) who, besides doing many things in the CNCF community, also hosts POPCAST where he started connecting technology leaders during the last year. In the podcast you learn a lot about security, the power of eBPF and how Falco aims to contribute to runtime security like k8s contributed to distributed computing.

Wonder what you learn when building k8s from scratch for a large enterprise? Wonder what you learn when automating delivery by connecting your different DevOps tools together?

Nana Janashia runs one of the most successful technical YouTube channels called TechWorld with Nana where she covers topics ranging from containers, docker, k8s, cloud native and DevOps. She basically takes her lessons learned and explains technologies and concept in a very easy way especially for folks that want to get started with.

In this episode we focus a lot on DevOps, what the right trades of a DevOps engineer are and how to get started. Thanks Nana for your time and all the additional resources we talked about during the episode that are listed below:

Have you ever thought about reorganizing data allocation based on production telemetry data? Have you ever thought about shifting compiler budgets to parts of your code that is heavily executed based on profiling information captured from your real end users? Whether the answer is yes or no you will be fascinated by Taras Tsugrii, Software Engineer at Facebook, who is sharing his experience on optimizing everything from compilers, to databases, distributed systems or delivery pipelines.
