This episode is about OSGi, the dynamic module system for Java. Our guests are Peter Kriens (OSGI's Technical Director) and BJ Hargrave (OSGI's CTO). We'll discuss what OSGi is all about and why and in which contexts it is useful. Additionally we are having a look at the different layers of OSGI and where and how they are used. Other questions discussed are: What means dynamicity in an OSGI environment? Where is OSGI used? What’s the future of OSGI? How does OSGI interact with existing middleware solutions? How can I run several versions of the same JAR at the same time? Where are OSGI’s problems?

John Wilkes from Google talks with Charles Anderson about managing large clusters of machines. The discussion starts with Borg, Google’s internal cluster management program.

Jeremy Jung talks with David Calavera about zero-downtime migrations and rollbacks with Kubernetes. In this episode we define migrations, rollbacks, and discuss how Netlify was able to migrate to Kubernetes and roll back off of it multiple times without impacting their users. David explains how developers can run old and new systems simultaneously, the importance of defining errors in your system, and when to apply fixes vs rolling back. We also discuss their decision to move to Kubernetes, and the benefits they received.

Andy Suderman, CTO of Fairwinds, joins host Robert Blumen to talk about standing up a kubernetes cluster. Their discussion covers build-your-own versus managed clusters provided by cloud services, and how to determine the number of kubernetes clusters an organization needs. Andy describes best practices for automating cluster provisioning, and offers recommendations about customizations and opinionation of cloud service providers, choice of container registry, and whether you should run complementary services such as CI and monitoring on the same cluster. The episode also examines the day 0/day 1/day 2 lifecycle, cluster auto-scaling at the cloud service level, integrating stateful services and other cloud services into your cluster, and kubernetes secrets and alternatives. Finally, they consider the container-network interface (CNI), ingress and load balancers, and provisioning external DNS and TLS certificates for cluster services.

Yeckezkel Rabinovich, CTO of Groundcover, speaks with host Philip Winston about observability and eBPF as it applies to Kubernetes. Rabinovich was previously the chief architect at the healthcare security company CyberMDX and spent eight years in the cyber security division of the Israeli Prime Minister’s Office. This episode explores the three pillars of observability, extending the Linux Kernel with eBPF, the basics of Kubernetes, and how Groundcover uses eBPF as the basis for its observability platform.

William Morgan, founder of the Linkerd service mesh and CEO of Bouyant, joins SE Radio’s Robert Blumen for a discussion of sidecars, service mesh, and a forthcoming enhancement to kubernetes to support sidecars natively. The conversation explores the origin of sidecars, sidecars and service mesh, and migrating service mesh to kubernetes. They take a deep dive into some aspects of running service mesh on kubernetes, the difficulties in running a sidecar container in a pod, and Kubernetes Enhancement Proposal (KEP) 753, which is intended to provide better native support for sidecar containers. William also gives some thoughts on the continuing relevance of service mesh.

Infrastructure engineer and Kubernetes ingress-Nginx maintainer James Strong joins host Robert Blumen to discuss the Kubernetes networking layer. The discussion draws on content from Strong’s book on the topic and covers a lot of ground, including: the Kubernetes network's use of different IP ranges than the host network; overlay network with its own IP ranges compared to using expanded portions of the host network ranges; adding routes with kernel extension points; programming kernel extension points with IP tables compared to eBPF; how routes are updated as the host network gains or loses nodes, the use of the Linux network namespace to isolate each pod; routing between pods on the same host; routing between pods across the host network; the container-network interface (CNI); the CNI ecosystem; differences between CNIs; choosing a CNI when running on a public cloud service; the Kubernetes service abstraction with a cluster-wide IP address; monitoring and telemetry of the Kubernetes network; and troubleshooting the Kubernetes network.

According to the religious liberty advocacy group Becket, Philadelphia-based foster families will be in court Monday fighting to end a new City of Philadelphia policy that is currently leaving numerous foster homes empty. In Sharonell Fulton, et al. v. City of Philadelphia, the City issued a new policy barring Catholic Social Services from placing children with foster families, solely because the City disagrees with the agency’s religious beliefs. That policy is causing serious problems for foster kids and families, and Catholic Social Services has asked a court for an urgent ruling by June 30. In March, the City of Philadelphia issued an?urgent call for 300?new foster parents to provide loving homes for some of the over 6,000 kids in Philadelphia foster care. That same month, the City abruptly barred Catholic Social Services, one of the city’s top-rated foster agencies, from placing children with foster parents like Sharonell Fulton, who has fostered over 40 kids in the last 25 years. This decision makes it exponentially harder for hundreds of children in need of foster care to find homes. Represented by Becket, Sharonell Fulton, Cecelia Paul, Toni Simms-Busch, and Catholic Social Services are asking the court to halt the City’s harmful policy and allow kids to be placed in a loving home.   What:  Oral Argument in Sharonell Fulton et. al. v. City of Philadelphia   Who:  Lori Windham, senior attorney at Becket Philadelphia foster families  When:  Monday, June 18 at 2:00 p.m. EST (arguments are expected to go three hours)   Where:  U.S. District Court 601 Market St., Philadelphia, Pa.    ###  Becket is a non-profit, public-interest law firm dedicated to protecting the free expression of all religious traditions?and has a 100% win-rate before the United States?Supreme Court.?For over 20 years, it has successfully defended clients of all faiths, including?Buddhists, Christians, Jews, Hindus, Muslims, Native Americans, Sikhs, and Zoroastrians?(read more here). 

Assistant Professor Richard Crowley from SMU’s School of Accountancy examines financial accounting using both archival and analytical methods for his research. Much of his archival work deals with large sets of unstructured data using high-powered computing algorithms to address accounting issues that are otherwise infeasible to approach. He has recently written two research articles on using a machine learning technique to assess the content of companies’ disclosures. In this podcast, he discusses how fraud and misreporting can be detected by studying a company’s financial statement using a machine learning technique, and shares how companies disclose financial information on Twitter, and how feedback from investors and others can influence this.
