A backup job missed 24 days of runs. Nobody knew. The CronJob looked fine in kubectl get cronjobs. No alerts fired. The last successful run timestamp in the status field just sat there, quietly getting older. The root cause: the CronJob controller had silently given up scheduling after missing 100 runs. Logged an error. Stopped trying. Moved on. This article explains why Kubernetes CronJobs are st
A defaced website is a curious problem. It's loud — anyone visiting the page can see something is wrong. But it's also quiet from a server's perspective: HTTP returns 200, your uptime monitor is happy, your TLS cert hasn't moved, and the CMS logs show a "successful" content update from a legitimate-looking session. The signal is on the rendered page, not in the metrics. I run a site at hi3ris.blue
A gestão de armazenamento na AWS sempre exigiu uma escolha difícil: a escalabilidade e o baixo custo do Amazon S3 (Object Storage) ou a facilidade de montagem e baixa latência do Amazon EFS (File Storage). Para aplicações legadas ou fluxos de trabalho que dependem de comandos de sistema de arquivos nativos, essa escolha muitas vezes significava reescrita de código ou custos elevados de infraestrut
You just ran a dependency scan and the report shows 133 vulnerabilities. 34 are Critical. 68 are High. The dashboard is red, the backlog is exploding, and every item looks urgent. The engineering team asks the obvious question: where do we start? This is where vulnerability remediation prioritization matters. Without a clear framework, teams either panic and chase the loudest CVE, or they ignore t
We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin
Three times in a decade. That's how often a Linux copy-primitive bug has blown a hole through container isolation. In 2016 it was Dirty COW. In 2024 it was Leaky Vessels. In 2026, a new class of Linux copy-primitive bugs is proving, again, that containers share a kernel. And that kernel keeps betraying them. The pattern is hard to ignore. Bugs in how the Linux kernel copies, references, or manages

Denver likes a good origin story. The city still keeps a marker for Louis Ballast and the Humpty Dumpty Barrel, the local spot tied to the cheeseburger's Colorado claim. That detail felt oddly right for SnowFROC 2026. A cheeseburger is a small upgrade that changes the whole meal. This year's conference kept returning to the same ideas in AppSec, such as how meaningful security progress often comes
