For the past couple months, I really delved into AI Agents for developing applications. My journey got more serious when my company rolled out a program for AI Acceleration by giving the Product & Tech division a $50 stipend for subscribing to an AI Agent of your choice. It was a great introduction, especially when these tools become more and more capable at helping write code. As time passed by, I started to offload more and more tasks to the AI Agent. My tool of choice is Augment Code, because I heard a lot of great feedback about it. It’s also the easiest tool for me to adopt as it basically lives on VS Code, which is suitable with my existing workflow. It was great and boosted my productivity, helped reduce mistakes, and I could even publish a full-blown full stack application to help my team keep track of our terraform staleness. ...

As a grown man and a father, I often find my focus shifting almost entirely to raising my family and guiding them to become the best people they can be. This mindset, while important, sometimes makes me forget about my own passions and curiosity about the world. I’m talking about starting new hobbies, exploring new activities—just doing things for myself, outside of my usual routine. But over the past two months, I’ve been trying to push myself a little further -— to explore more, to step outside my routine and even outside my comfort zone in the digital world (like starting yet another software project). Suddenly, I found myself on a “new hobby spree.” Honestly, I enjoy all of them, but sometimes I wonder if I’ll ever be able to stop, or if maybe I’m just feeding my inner child. I’m not really sure, but it’s been an interesting ride. ...

November 2024, I got a very bad news from my office. They said that I am one of 13 employee that they have to terminate for cost saving and profitability. It was horible, and was surprising for me because troughout the year, nothing goes into my radar, I dont make any big mistakes, in my opinion I even accomplish quite of achievement. I managed to save aroud EUR 150.000 that year, I am rebuilding the company IT Operation departement by hiring a really good candidate, so on and so forth. But unfortunately, those seemingly not enough for saving the company for pursuing profitability. ...

It is quite common when your project use Kubernetes, your ingress controller of choice is Ingress Nginx. It’s well known, cloud agnostic, huge support from community. The story begin Let’s say you have your shiny new project ready to run on top of kubernetes with Ingress Nginx. You push your image to registry, and configure all lovely yaml from Deployment, Service, and Ingress, one kubectl command later, boom it runs and accessible perfectly. ...

Last week I launch my own project at GitHub called Pasolo, a simple single user authentication server using passkeys. I built all the parts, from backend, frontend, as well as releases. It was really eye opening experience for me, I learn a lot of building whole full stack application Proper release flow Many times in my professional life, I handle CI/CD pipeline, which mainly handling build, release, and deploy. I could even say, thats one of my expertise in Software Engineering. And yet, building my own project, that I wish can be easily used by other, is not that simple. ...

At my current company, we utilize Kubernetes on top of Google Cloud (GKE) as our platform of choice to runs our workloads. The core workload that we runs to serve our users is deployed as Kubernetes Job, created via client library of Kubernetes. Because the nature of our traffic, sometimes Kubernetes Job creation can be burst in high number, and many of the fails due to the following error Operation cannot be fulfilled on resourcequotas "gke-resource-quotas": the object has been modified; please apply your changes to the latest version and try again I can’t deny but this error quite strange, especially this is the return value of the Kubernetes client library. Exploring what’s gke-resource-quotas means, I found that its a ResourceQuota resource on Kubernetes, that automatically injected on our Kubernetes cluster. ...

Kubernetes has a simple volume type called emptydir where it asks the node to spare a disks that mounted on runtime. This type of volume really useful to store temporary files, logs, etc. This volume “survive” on container restarts, but removed on pod removal, makes it helpful for persisting data across restart process, without consumimg unnecessary disks. But things gets more interesting afterward. Imagine a workload that runs as Kubernetes Job, then suddenly failing / misbehaving and we need to check the temporary files that its produces to emptyDir. Sure, mounting PVC could be one way to solve this, but it adds another layer just for debugging purposes. ...

Having always free computes from cloud provider, really open up a new world of “nerd”-ing 🤣 While test this new plugin editor, I’d list all the tools that I currently use Tailscale A great prerequisite to do!
