In this episode of DC Power Hour, the Battery Blarney duo of George and Allen, along with our resident load bank technician and engineer Josh Fox, delve into the intricacies of load testing and load banks. They emphasize the critical importance of load testing in assessing battery capacity and highlight challenges faced by utilities in allocating manpower for comprehensive testing. The conversation explores IEEE and NERC standards for load testing, including acceptance tests and modified performance tests, and offers practical insights from field experiences. The hosts conclude by discussing strategies like cell jumping and the necessity of adjusting charger voltages, providing valuable tips for professionals in battery maintenance.Episode Highlights:4:59 – A common question I get is "why do we have to do a test for eight hours?"9:41 – When you're recharging the battery, you're shoving maximum current in into it. Depending on the design of the power system, you could be shoving two or three hundred amps into that battery.20:23 – There's also a couple of excellent papers on load testing itself. One by, I'll give a plug here, one by an old friend of mine and yours, Rick Tresler. And Another one by I believe it was Steve Clark on rate adjusted method.22:11 – You're putting yourself at risk because you're working on 120 volts with a lot of current around, and you're putting the system at risk if you get it wrong.49:14 – Are there certain pitfalls or certain things that people need to worry about in order to do a discharge test correctly?

Usually Tuesdays at 11am PT. Older video versions available there too. Brian #1: The Basics of Python Packaging in Early 2023 Jay Qi Good description of a minimal-ish pyproject.toml file, which includes a build backend and project metadata. That's all you need for a Python-only project. Discussion of how to choose a build backend. Mostly it's baed on extra features you might want, like hatchling's include/exclude features for source distributions. Some discussion of frontend choices. Nice discussion of non-Python-only builds. Specifically, if you need to compile C or C++ extensions, you can use scikit-build-core, or meson-python, or setuptools. Related: "Sharing is Caring - Sharing pytest Fixtures" by Brian Okken (PyCascades 2023) My PyCascades 2023 on packaging pytest plugins is up on YouTube Michael #2: vecs via Oli Python collection-like interface to storing and searching vectors in postgres. Vector search is a key component in building AI chatbots, and semantic document search. If you're familiar with the space, it's effectively Pinecone built on free OSS It's under the Supabase github org but it's fully open source, and compatible with any pgvector vendor, e.g. RDS, or locally in docker If you're on macOS and need Postgres, Postgres App is a good option. Brian #3: Introducing Grasshopper - An Open Source Python Library for Load Testing Jacob Fiola “Grasshopper is a library for automated load testing, written in Python.” Open source project from Alteryx, On GitHub and PyPI under the name locust-grasshopper Built on Locust. Adds Tag-based suites for trend analysis and evaluating changes. Custom trends. Useful for actions that span multiple http calls, and you want to see timing trends for the whole action. Checks. Checks validate boolean conditions in the test. Custom tagging for all metrics Send data to time series db & dashboards. Thresholds. Reporting results to other locations. Some reusable base classes that take care of the majority of the boilerplate that tests often contain Readme has a very thorough introduction including configuration and samples. Michael #4: memocast by Daniel Engvall A small iOS app for e.g. iPhone that allow you to add links heard in podcasts into reminders. Good example of how to use Pythonista to build python scripts for iOS Pythonista just made an update (2 weeks ago) so that'd use Python 3.10 on the iOS which makes it even more interesting.

Les tests de charge sont une étape importante du développement d'une application et de son cycle de vie. En effet, ils permettent de tester les limites de certains composants, de valider une architecture et de s'assurer qu'elle se met à l'échelle correctement, mais aussi parfois d'éliminer des bugs de l'application elle-même. Mais avoir un bon outil, capable de vraiment tester l'application au travers de parcours utilisateur et de remonter des données fiables n'est pas chose évidente. Et même Wikipedia a une définition erronée du test de charge. Aujourd'hui, je reçois donc celui qui fait mentir Wikipedia, j'ai nommé Stéphane Landelle. Stephane est le CTO de Gatling, une solution de test de charge open source écrite en Scala et fournissant un DSL Java permettant de créer du test as code.

Carter Morgan and Stephanie Wong host Shopify guests Camilo Lopez and Tai Dickerson this week. Shopify streamlines the online purchasing process so merchants and customers can transact with confidence. Camilo and Tai talk in-depth about Shopify's tech stack and why the choices made are so important to performance. Shopify engineers use a combination of Ruby on Rails, MySQL and Google products like Kubernetes. Resiliency systems like active-active configurations, chat ops for quick solutions, and bot and overload protection are worked in. By leveraging these tools and staying flexible in their resiliency efforts, Shopify is able to adjust to new merchant requirements and teams are able to work efficiently. While tech continues to progress and change, the Shopify culture remains a driving force for advancement, Camilo tells us. The company ideals and axioms help steer the brand and dictate which technologies they'll use to solve new and changing client demands. The 2014 outage shaped the future of these cultural ideals, emphasizing the need for quick action and resiliency components like constraints to ensure system safety. Shopify engineers also built enhanced testing tools like Toxiproxy to simulate poor network conditions and account for potential issues. The 2021 Black Friday Cyber Monday shopping season was Shopify's biggest yet. Camilo and Tai describe how Shopify's resiliency culture and intense prep work made the biggest shopping weekend of the year so successful. By offering educational tools and a support network that values good communication, their company culture continues to grow, and Tai tells us how it's not just the software that should be resilient. Building a resilient, flexible company culture is just as important. Camilo talks about Shopify's recent shift to a completely remote work place and the new challenges and opportunities it presents. Camilo Lopez Camilo has worked at Shopify for more than 10 years, he has been an IC and a manager leading teams that take care of Shopify's scalability and resiliency.

During the recording of this episode, we are in the week of Black Friday. An exciting week for people hunting for bargains. And also for a lot of our colleagues.What this episode coversWhether that is from a commercial point of view or an engineering one.All the eyeballs on our website, bring a lot of traffic. And consequential a lot of load on our systems. In this episode, we focus on one aspect of preparing for a large load: Load Testing. In this episode, we are going to talk about Load Testing with Locust. An open-source load testing tool.Triggered by our guest's presentation during the spaces summit, we wanted to know more about this and share it with you.What is Locust?Why did we start using Locust for Load Testing?Examples of Load tests and Performance tests performed with this toolWhat did we need to setup for it?How to configure your Locust testsHow to run your tests on KubernetesWhat were the challenges?How does it make use of the cloud benefits like scalability?GuestsLeon van Wijk; Full Stack Software Engineer at Craftsmen and engineer in our Logistics TeamNotesDistributed load testing with LocustLocust presentation at the Spaces SummitPerformance testing the Chat App

In a previous Tag1 Team Talk, we discussed https://www.tag1consulting.com/blog/how-analyze-goose-load-testing-results-using-new-relic (How to analyze Goose load testing results using New Relic). During testing, a bug was discovered! This team talk goes into detail about what the bug was, how they narrowed down the scope of the problem, and how to fix it.  In this test, http://tag1.com/goose (Goose) found a problem with Drupal's Quick Edit feature. Quick Edit is a staple of content creators, enabling them to make changes directly in content, even if that content is wrapped in blocks or other Drupal layout features. Once again, join Goose creator and CEO of Tag1 Consulting Jeremy Andrews, VP of Software Engineering and Goose contributor Fabian Franz, and Managing Director Michael Meyers as they dig into the results of a Goose Attack, and how this Goose test found something that other analyses did not. 

Need to put together a load test for your software but don't know where to start? Want to improve your current performance-testing efforts? In this episode, Leandro Melendez (AKA Sr. Performo) will discuss his new book, The Hitchhiking Guide To Load Testing Projects. Discover proven performance principles and practices from this fun, step-by-step walk-through guide. Don't miss it!

“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.https://www.srperf.com/podcast/https://www.srperf.com/el-youtube-channel/https://www.srperf.com/presenter/Pre-order the book herehttps://www.amazon.com/dp/B09C4ZT1LB

In today's Tag1 Team Talk, Managing Director Michael Meyers sits down with VP of Software Engineering Fabian Franz, and CEO Jeremy Andrews for a coordinated demonstration of https://github.com/tag1consulting/goose (Goose) and https://newrelic.com/ (New Relic). Goose is the highly performant load testing framework written in Rust, and New Relic is one of the most highly regarded performance analysis tools in use today.  Jeremy is the creator of Goose and Fabian is a major contributor to the project. In this demonstration, Jeremy and Fabian run a Goose test simulating 1200 users using the Umami profile for Drupal 9, on a R5N 8x large EC2 instance. Join us to see how Goose performs with multiple types of users, and how and why we use New Relic to troubleshoot issues as Goose pinpoints them.

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.Linkedinhttps://www.linkedin.com/in/hveldstra/SLOconf: Production load testing as a guardrail for SLOs - by Hassy Veldstrahttps://www.youtube.com/watch?v=Y20K1mJB6tkBlog: Load testing.

How do you build Python applications that can handling literally billions of requests. I has certainly been done to great success with places like YouTube (handling 1M requests / sec) and Instagram as well as internal pricing APIs at places like PayPal and other banks. While Python can be fast at some operations and slow at others, it's generally not so much about language raw performance as it is about building an architecture for this scale. That's why it's great to have Julian Danjou on the show today. We'll dive into his book "The Hacker's Guide to Scaling Python" as well as some of his performance work he's doing over at Datadog.
