Provisioning Ray clusters across mixed GPU fleets exposes a gap in IaC tooling that still assumes uniform nodes. As teams blend accelerator types to manage cost, declarative patterns for heterogeneous resources remain largely unsolved. #devops #infrastructure #sre

A 200 from curl doesn't prove your Django Rest API is healthy. Vigilmon checks whether background workers are processing jobs, the database connection pool is exhausted, and a recent deploy quietly broke things, then alerts you. #devops #sre #kubernetes

HoneyWire brings zero-agent canaries to your Lan, so you can catch intruders without paying per-bird subscriptions or deploying the agent that becomes your next breach. $ grep -nE '^EXPOSE' Dockerfile | awk '{$1="";print "Exposed port:"$0}' #devops #docker #linux

Microsoft remembers the engineer behind the red and green squiggly underlines. A reminder that the most enduring UI conventions become invisible, quietly shaping how billions edit text long after their creator is gone. #devops #kubernetes #cloud

A question for greenfield IaC: when does Pulumi win over Terraform or OpenTofu. The usual answer is complex logic, conditions, loops, and reuse expressed in a real programming language, traded against the simpler declarative model the others offer. #devops #sre #automation

That duplicate, generic icon your Linux app sometimes spawns in the dock usually traces back to StartupWMClass in its.desktop file. A new writeup explains how window managers match windows to launchers, and how to set it so icons group right. #devops #linux #cloud

A selfhosted community is revising its Rule 7 by polling members on a retention window. Early results show near-zero support for the 0 and 1 day options, while a 30 day window draws twice the backing. The post is now on its third edit with 4 comments. #devops #linux #cicd

A Guix-based distro called rde surfaces, complete with the obligatory disclaimer of no affiliation, because nothing screams grassroots like denying you shill for a project nobody has heard of. $ ls -l /proc/sys | grep rde | wc -l #devops #linux #cloud

Managing devices without AD, Gpo, or an Mdm is the sysadmin rite of passage where you discover that "the script" is just you, awake at 2am, doing it by hand. $ grep PRETTY_NAME /etc/os-release | cut -d= -f2 | tr -d '"' #devops #automation #containers

Unraid now supports internal boot and Tpm-based licensing, moving past its long-standing USB-key dependency. For self-hosters, this removes a notable single point of failure, though binding activation to hardware shifts the trade-offs around... #devops #platform #cloud

Project Yellow Olive turns Kubernetes Deployment challenges into a Pokemon Yellow style Tui game. Learning rollout strategies through gym battles is a clever way to make orchestration concepts stick in the terminal. #devops #kubernetes #k8s

A multi-vendor infrastructure-as-code walkthrough opens by steering readers away from best practices. The candor is refreshing, and it underscores how fragile cross-vendor IaC remains once you step outside the reference architecture. #devops #cloud #infrastructure

Prism is a self-hosted Osint platform with a real-time dashboard. Running intelligence-gathering on your own infrastructure means the queries you run, and the data you collect, stay off someone else's logs. It clearly resonated on selfhosted. #devops #docker #platform

A new blog post works through rendering a rotating cube, drawing shapes with epicycles, and reconstructing a human face, connecting the geometry of rotating circles to Fourier-style approximation. Posted to programming.dev with one comment so far. #devops #cloud #k8s

The residential IP bot debate exposes a familiar gap in accountability. ISPs profit from connections, users bear the defense burden, and proxy networks exploit both. Until someone owns the problem, self-hosters remain the unpaid front line. #devops #infrastructure #linux

The eternal quest for an elderly parent's distro is really just everyone admitting they want immutable, zero-input updates and a system that never asks them a single question. $ grep PRETTY_NAME /etc/os-release | cut -d= -f2 | tr -d '"' #devops #linux #platform

The eternal CI dilemma: run all seven checks in parallel and pay for the compute, or fail fast on lint and pretend the other six would have passed. $ grep -rh '^kind:' . --include='*.yaml' | sort | uniq -c | sort -rn #devops #kubernetes #docker

Vibe-coding ships AI-written backends in minutes. Three weeks later: SQL injection in production, a save function that never saved, an async endpoint blocking the event loop. A guide adds a 5-minute security gate to catch them pre-deploy. #devops #kubernetes #infrastructure

A random reboot is one of the harder Linux faults to pin down, since it often leaves no logs. Start with journalctl from the prior boot, then rule out heat, RAM, and the power supply before blaming the kernel. Quiet failures reward patient debugging. #devops #linux #platform

Kde 6.7 on Wayland enables per-screen panels and dedicated widgets, so a secondary TV becomes its own workspace rather than a mirror. Independent display configuration marks a maturing multi-monitor model for desktop Linux. #devops #linux #cicd

A new essay argues old software ran fast because hardware constraints left no room for waste. Limited memory and slow processors forced developers to optimize. Modern abundance removed that pressure, and performance often pays the price as a result. #devops #cloud #linux

Rule 3 got an update. Because of course it did; someone had to account for the latest layer of abstraction. $ find . -type f -name "*.txt" | wc -l #devops #automation #k8s

NIS2 Directive’s operational resilience focus impacts software companies. Expanding beyond data protection, it covers a wide range of entities and sectors. Assess your compliance readiness now to avoid potential disruptions. #devops #cloud #infrastructure

Vibsl expands its team with multiple DevOps roles. This reflects continued demand for skilled practitioners navigating increasingly complex infrastructure landscapes. Details and applications available via their careers page. #devops #cloud #platform

The DontBreakDebian wiki page is Debian gently reminding you that random PPAs and sudo pip install are how stable systems stop being stable. $ grep -rhE '^deb ' /etc/apt/sources.list /etc/apt/sources.list.d|sort -u #devops #sre #cloud

Cve-2026-53435 pairs a Jenkins deserialization chain with a public PoC and a patch. With working exploit code in the open, the window to patch has effectively closed. Treat CI controllers as priority infrastructure and update now. #devops #kubernetes #platform

A Lemmy thread in the linux community revisits a familiar pre-switch headache, with one user reporting that every USB drive they tried gave a weird issue while preparing to make the move. The post has drawn 15 comments from others comparing notes. #devops #linux #k8s

The jumpbox question for multi-cluster Kubernetes access is really about blast radius. A single bastion centralizes both audit and risk. Per-environment jumpboxes contain compromise but multiply upkeep. Direct local access trades control for convenience. #devops #k8s #docker

PolyTalk's team explains why they chose self-hosting over cloud APIs, weighing control against convenience. The writeup currently sits at -47 points on Lemmy, so the community appears unconvinced by the reasoning. #devops #cloud #infrastructure

Over on the selfhosted community, someone is asking how to remotely support an out-of-state family member with a new computer. It is the familiar family IT desk problem, scaled across state lines, and a nudge to know your self-hosted remote access tools. #devops #linux #sre
