Dev Environment for Agentic Coding
이 글은 AI 코딩 에이전트를 활용한 개발 환경의 중요성과 최적화 방안에 대해 다룬다. 특히 개발 속도와 품질을 높이기 위해 병렬 에이전트 운영, 컨테이너 기반 개발 환경, 핫 리로드, 버전 관리된 dotfiles, 그리고 원격 접근성 향상을 위한 Tailscale 활용 등을 강조한다. 또한, 대규모 프로젝트에서의 테스트 자동화와 보안 문제 해결 방안도 함께 논의한다. 메타의 OnDemand 시스템과 같은 빠른 개발 환경 구축 사례를 소개하며, 개발자가 에이전트와 함께 효율적으로 작업할 수 있는 환경 구축이 핵심임을 제시한다.

Pro-Grade Ham Radio Displays: Integrating OpenHamClock into PiSignage

758 words, 4 minutes read time.

A Helping Hand Needed for a Fellow Programmer

I’m reaching out to see if you can lend a hand to a talented software developer who’s currently on the job hunt. With over 30 years of experience in C#, .NET (Core/6–8), REST APIs, SQL Server, Angular/Razor, Kubernetes, and cloud CI/CD, he’s a seasoned pro with a proven track record of leading modernization projects and delivering production systems.

Some of his notable accomplishments include DB2 to SQL migrations, building real-time SignalR apps, and developing full-stack API and frontend projects. Based in Southeast Michigan, he’s looking for senior engineering, architecture, or technical lead roles that will challenge him and utilize his skills.

If you’re in a position to help, you can check out his resume and portfolio at http://charles.friasteam.com.

Let’s all look out for each other – if you know of any opportunities that might be a good fit, could you please consider passing this along to your network?

If you are a ham radio operator, you know that a HamClock is the ultimate shack companion. But what if you want to move beyond a dedicated small screen and integrate that data-rich display into a professional digital signage environment?

By using PiSignage, you can rotate your HamClock with other station metrics, weather, or club announcements. However, getting a clean, secure, and “pop-up free” experience requires a few tricks.

In this post, I’ll show you how to deploy OpenHamClock using Docker and how to strip away the UI clutter for a seamless kiosk experience.

The Setup

To follow along, you will need a PiSignage server instance. I personally run mine as a Docker container, which keeps the server stack isolated and easy to back up.

1. The Docker Compose Configuration

PiSignage and modern browsers often require secure contexts (HTTPS) for certain features. Since the standard HamClock output is HTTP, we’ll use a two-service setup: the clock itself and a lightweight SSL-wrap sidecar using socat and openssl.

docker-componse.yml

2. Silencing the “What’s New” Pop-ups

When using HamClock as a signage element, you want it to be “set and forget.” The “What’s New” slide-ins are helpful for desktop users but ruin a clean kiosk display.

While there is a formal change request pending for a toggle, you can currently “force” these elements to stay hidden by injecting a bit of CSS directly into the distribution files. Run this command within your app environment:

3. Setting Up the Slide in PiSignage

Once your containers are humming along, you need to tell PiSignage how to display the clock.

Create the Weblink Asset

Pro Tip: The ?kiosk=true suffix is critical. It tells HamClock to hide its own internal menus and headers, giving you a dedicated, high-contrast dashboard perfect for a wall-mounted display.

Deploy to Your Player

Your screen should refresh and show a beautiful, clean HamClock interface within seconds!

Running PiSignage in Docker?

For those of you looking to keep your entire server stack contained, running the PiSignage central server in Docker is the way to go. It keeps your host OS clean and makes management a breeze.

If you’d like me to discuss how to set up a dockerized PiSignage server, please comment below!

Call to Action

Getting this stack to play nice wasn’t a “one-and-done” install. It was a hard-fought process that took multiple attempts to finally crack the code on bypassing those “What’s New” screens and forcing a clean kiosk display. But the victory is in the uptime.

Don’t just lurk. If you’ve got the guts to show how you’re rebuilding your station on the wreckage of the old ways, drop a comment below. How are you occupying the victory today?
