Lucas and Luna examine the Linux ecosystem as it powers everything from cloud servers to embedded devices. They trace the evolution of major distributions — Fedora's upstream-first philosophy, Debian's stability-first governance, and the commercial strategies behind Ubuntu and RHEL — without rehashing release notes. Each episode picks one layer of the stack: the container runtime that changed deployment (Docker, Podman), the systemd debate, or why Wayland still hasn't fully replaced X11 on the desktop. They also cover real-world migrations: a startup moving from CentOS to Rocky Linux, a government agency choosing OpenSUSE Leap for long-term support, and the kernel patching workflow at a FAANG-scale datacenter. Lucas brings the command-line fluency — package managers, filesystem hierarchy, SELinux contexts — while Luna asks the questions that matter to sysadmins and developers: What breaks when you upgrade? How do you audit a distro's supply chain? Can Linux ever win the desktop without

How Linux Kernel BPF Transforms Network Security
Sep 9, 202612 minS4
We look at how eBPF has moved from a niche debugging tool to the backbone of modern cloud networking, using Cilium and Envoy as primary examples. With over two hundred thousand contributors now interacting with the kernel through this interface, we examine why enterprises are rewriting their security policies in userspace rather than waiting for kernel updates. This shift allows for near-zero-latency packet inspection, fundamentally changing how companies like Google and Netflix handle traffic encryption and load balancing without sacrificing performance. #eBPF #LinuxKernel #NetworkSecurity #CloudNative #Cilium #EnvoyProxy #OpenSource #DevOps #Infrastructure #TechTrends2026 #SystemAdministration #ContainerNetworking #FexingoBusiness #BusinessPodcast #LucasAndLuna #LinuxPodcast #TechnologyNews #EnterpriseIT Keep every episode free: buymeacoffee.com/fexingo
How Linux Containers Solve the Dependency Nightmare
Sep 8, 202611 minS4
Most developers treat containerization as a deployment tool, but the real value lies in dependency isolation. We explore how modern distroless images and build-time pinning eliminate the 'it works on my machine' problem. Using Ubuntu Jammy and Alpine as case studies, we break down why stripping away unnecessary libraries reduces attack surfaces by up to sixty percent. This is a deep dive into the operational reality of shipping reliable software stacks. #LinuxContainers #DockerImages #Distroless #DevOpsLife #SoftwareEngineering #CloudNative #TechInfrastructure #SystemAdministration #OpenSourceTools #BuildPipelines #SecurityBestPractices #ApplicationDelivery #ServerStack #FexingoBusiness #BusinessPodcast #TechTrends2026 #CodeQuality #OperationalExcellence Keep every episode free: buymeacoffee.com/fexingo
Linux Kernel Watchdog: How OOM Killer Saves Systems
Sep 7, 20269 minS4
We dig into the Linux Out-Of-Memory killer, the kernel feature that makes hard decisions when RAM runs dry. Lucas and Luna break down how the OOM score works, why it sometimes targets the wrong process, and what system administrators can do to protect critical databases from premature termination. We look at specific tuning parameters like oom_score_adj and real-world scenarios where letting a service crash is better than freezing the entire server. #LinuxKernel #OOMKiller #SystemAdministration #ServerStability #MemoryManagement #TechEngineering #OpenSource #DevOps #SysAdminTips #LinuxDistros #CloudInfrastructure #DatabaseReliability #FexingoBusiness #BusinessPodcast #TechTalks #SoftwareDevelopment #LinuxCommunity #ITOperations Keep every episode free: buymeacoffee.com/fexingo
How Linux Kernel Lockdown Hardens Enterprise Security
Sep 6, 202613 minS4
We examine the practical implications of Linux kernel lockdown mode for enterprise security. With modern deployments increasingly reliant on immutable infrastructure, understanding how this feature restricts user-space access to kernel memory and device files is critical. We break down the three levels of lockdown, analyze why organizations like Red Hat enable it by default in Fedora Server, and discuss the trade-offs between strict security controls and legitimate administrative tasks like debugging or custom module loading. #LinuxKernel #LockdownMode #EnterpriseSecurity #RedHat #FedoraServer #ImmutableInfrastructure #KernelHardening #SystemAdministration #Cybersecurity #OpenSource #TechPolicy #ServerManagement #FexingoBusiness #BusinessPodcast #LucasAndLuna #DevOps #CloudComputing #TechnologyNews Keep every episode free: buymeacoffee.com/fexingo
We break down how Linux cgroup v2 memory pressure controls work in practice, using a real-world scenario where a misconfigured container triggers throttling before OOM kills. Lucas and Luna explore the difference between soft limits and hard limits, why reclaim paths matter for latency-sensitive apps, and how to read memory.stat to catch issues early. This episode covers concrete metrics, kernel behavior under load, and practical debugging steps for DevOps engineers managing server stacks in September 2026. #LinuxKernel #CgroupV2 #MemoryManagement #DevOps #ServerStack #OpenSource #Containerization #SystemAdministration #PerformanceTuning #LinuxSysadmin #TechPodcast #FexingoBusiness #BusinessPodcast #TechnologyNews #Engineering #CloudInfrastructure #LinuxDistro #ITOperations Keep every episode free: buymeacoffee.com/fexingo
Every question we get asked before someone starts their trial.
If you have a concern about deliverability, AI quality, data privacy, or whether this will actually work for your specific situation, it's probably answered below.
What is the difference between Founder Solo and Founder Pro?
Founder Solo gives you 50 AI pitches per month using the credit model (Standard pitches cost 1 credit, Enriched pitches cost 2). Founder Pro raises that to 200 credits per month and adds full Booking Probability access, unlimited Magic Match, Apollo enrichment credits, and data export capabilities. Both plans use the same credit system, so you can stretch your monthly budget further by using Standard-mode drafting.
How do agency tiers work?
Agency tiers have no base fee. You pay per managed client and per talent profile. Agency Standard is $199 per client per month; Agency Pro is $399 per client per month. Both add $39 per talent profile per month. Your own team's user seats are always free.
What is a talent profile?
A talent profile represents one person (founder, executive, or spokesperson) you are booking onto podcasts. It includes their bio, topics, headshots, and outreach history. Team plans include 5 profiles; agency plans are pay-as-you-go.
Can I switch plans later?
Yes, at any time. Upgrades take effect immediately; downgrades apply at the end of the current billing period. Contact support if you need help migrating between plan families.
Do you offer a free trial?
Every paid plan includes a 15-day free trial. Your card is saved at signup but you will not be charged until day 16. Cancel any time from your dashboard.
What happens if I cancel?
You keep access until the end of your current billing period. No charges after that. Your data is retained for 30 days in case you reactivate.
Is the 20% annual discount automatic?
Yes. Select Annual on the pricing toggle and the discounted price is applied automatically at checkout. The annual price shown is the full year cost.
What if I have more than 50 profiles or 20 clients?
That is our Enterprise tier. Contact our sales team and we will build a custom plan with volume pricing, a dedicated account manager, and SLA guarantees.
