.zshrc tmuxinator tease | Command Line Heroes EP3 - Bengaluru

Jan 31, 2026

Command Line Heroes is a meetup series for developers, SREs, and terminal nerds who love living inside the shell.

​In episode 3 from Bengaluru, Saurabh Hirani (Principal SRE at One2N) walks through a real-world debugging story where Kiro CLI quietly breaks his beloved Tmuxinator setup.

​This talk is a deep dive into how a “simple” autocomplete feature ended up sitting between Ghostty/VS Code, tmux, and zsh, and why things started to go weird: tmux panes showed commands but refused to execute them, shell startup got slower, and mysterious processes began to appear.

​Along the way, Saurabh uses LLMs, exec, and process inspection to peel back the layers and explain what’s really happening inside your terminal sessions.

CLI Heroes Ep3 was an in person meetup held on 31st Jan 2026, thanks to Smarsh Inc - Bengaluru for providing the venue, this is just a small snippet of the things that happened at the meetup. Make sure to follow One2N events on luma to be notified of upcoming events: https://one2n.io/meetups

Kubernetes for Hybrid Cloud Environments - Harshwardhan Mehrotra - #60 Kubernetes Pune Meetup

Harshwardhan Mehrotra

SRE @One2N

Scaling Kubernetes workloads across 40+ data centers is hard – especially when you must meet strict data residency and latency requirements while still leveraging the public cloud. In this talk from the Kubernetes Pune Meetup, Harshwardhan Mehrotra (Site Reliability Engineer at One2N) walks through how his team designed and operated an EKS hybrid setup for a large betting platform with data centers across the US, UK, and Europe. You’ll see how they connected on‑prem worker nodes to an AWS EKS control plane, handled networking at scale, and kept the developer experience close to a “normal” EKS cluster. What you’ll learn: - Why EKS hybrid was chosen over fully on‑prem or fully cloud, and how regulatory and latency constraints shaped the architecture. - How to design pod vs node networking, routable vs non‑routable pod networks, and when to bring in BGP. - How to connect 40+ data centers to AWS using Direct Connect / site‑to‑site VPN and Cilium/Calico CNIs. - How to expose apps using F5 and Istio/NGINX ingress when ALB is not an option. - Real‑world issues with DNS (CoreDNS, Route 53 limits, node‑local DNS) and traffic distribution, plus how they fixed them. - Lessons on egress control, firewall bottlenecks, add‑on placement (Argo CD, KEDA, Prometheus, etc.), and building repeatable playbooks for on‑prem nodes. - This talk is ideal for platform engineers, SREs, and architects running Kubernetes across data centers and cloud, or evaluating EKS hybrid for regulated workloads.
