Recently, I’ve been asked about my smart home setup and decided that I’ve gathered enough experience to share it with others, so people can avoid the pitfalls that I fell into. What Is a Smart Home? A smart home consists of many scattered devices that interconnect with each other to follow your orders. For example, a thermostat that measures temperature and turns your air conditioner on or off on demand. It doesn’t only make your life easier—it will also reduce your electricity bill. ...

Almost a year ago I purchased a Beelink Mini S12 Pro (N100-based mini PC) from AliExpress. Initially I wanted to install only Home Assistant and looked for something simple and cheap. I never thought I would need something more powerful. How wrong I was. Initially I planned to install HA OS, but then thought that installing it using a container and docker-compose would give me more room to test and debug. I knew that if something broke, it would be much easier to restore than using HA OS. ...

The Problem I was using k9s to check logs on my K3s homelab cluster when I hit this frustrating error: to create fsnotify watcher: too many open files stream closed: EOF for development/drawdb-ddf8d9569-grfff (drawdb) The log stream would just close immediately, and I couldn’t see anything. Annoying. What’s Actually Happening Here’s the thing - this isn’t a problem with k9s on your laptop. It’s happening on the K3s node itself. When applications watch files (like development tools, file syncing services, or even k9s monitoring your cluster), Linux uses something called inotify watchers. There’s a limit to how many of these you can have. ...

Note: This post preserves and references the solution from Ivan Aloneguid’s original article. Full credit goes to the original author for this elegant solution. Quick Solution If you use IntelliJ IDEA with a dark theme but want a white Markdown preview, here’s the simplest fix: Go to File → Settings → Languages & Frameworks → Markdown In the “Custom CSS” field, add: body { filter: invert(1); background: #fff; font-family: 'Segoe UI'; font-size: 16px; } img { filter: invert(1); } Click Apply and OK Why This Works The CSS uses filter: invert(1) to flip the dark preview to light. Images are also inverted to preserve their original appearance. You can customize the font family and size to your preference. ...

I’ve been noticing more political content and engagement on LinkedIn lately. While I understand we’re living through complex times both in Israel and globally, and people naturally want to share their perspectives, I wanted to offer a gentle reminder about the potential professional risks. When recruiters and hiring managers review your profile, they inevitably see your activity—including political posts you’ve liked or shared. Even the most professional individuals can be unconsciously influenced by views that differ from their own. This bias might affect their perception of you as a candidate, even if they’d never admit it to themselves. ...

I may not be the smartest person in the room, but after working closely with Claude and ChatGPT over the past few months, I want to share some observations. AI won’t replace programmers—at least not anytime soon. For AI to truly replace programmers, one of two conditions must be met: Accept that our codebases will eventually become completely unreadable to humans. Once no human can maintain the code, all bugs must be fixed by AI. Inevitably, the AI will encounter a bug it can’t solve, and we’ll need human programmers to refactor and essentially rewrite everything from scratch. ...

Just installed and played a little bit with Claude Code, and it’s disturbingly good. I played with it for a few hours—it took me that time to write an MCP server from scratch, create a simple OAuth proxy, debug it, and then perform some refactoring to make it modular and maintainable. Yes, without human touch it writes spaghetti code that works but is barely maintainable. However, the nature of programming is changing; you will need to read more than write. But without writing, you won’t be able to read and understand. I think developers with many years of experience who know how to write code and are able to adopt new AI tools will be invaluable, because one such developer can easily replace a small team. But for newcomers, it will be extremely difficult to gain the required experience to work productively with AI tools. ...

You know what the biggest appreciation for an employee is? It’s not a title, not a good review, and not even a salary raise. The best appreciation comes when your old teammates or managers call you to join them at their new company. When there are no company rules involved, no need to be nice just to keep good work relationships—when your former manager needs to hire someone and remembers you, decides to message or call you to join their new team. ...

No, AI won’t take jobs from us, not yet. Claude struggled to write a script to unseal the vault in my k8s cluster until I split the job into small chunks and guided it step by step through what needed to be done.
