I’ve been using Windows for years—it always “just worked” for me.

But in 2026, I kept hearing the same thing everywhere: Linux is faster, more private, and gives you more control. So I decided to test it myself.

I switched to Linux and used it as my main OS for 30 days.

The first few days felt fast and clean… but as time went on, I started noticing things weren’t as simple as Windows. Installing apps wasn’t always straightforward, and plug-and-play didn’t always work I had to set things up manually.

But after a week, things started to click. The system stayed fast, no ads, no forced updates—and I actually started enjoying the experience.

So… can Linux really replace Windows in 2026?

I’ve shared my full experience, including what worked, what didn’t, and who should actually switch.

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

 services:    openhamclock:      image: ghcr.io/accius/openhamclock:latest      container_name: openhamclock      expose:        - "3000"      environment:        - CALLSIGN=<CALL SIGN>        - LOCATOR=<Grid Square Locator>        - THEME=dark        - UNITS=imperial      restart: unless-stopped     ssl-wrap:      image: alpine      container_name: hamclock-ssl      ports:        - "3000:3000"      command: >        sh -c "apk add --no-cache socat openssl &&                openssl req -x509 -newkey rsa:2048 -keyout /tmp/key.pem -out /tmp/cert.pem -days 365 -nodes -subj '/CN=localhost' &&               cat /tmp/cert.pem /tmp/key.pem > /tmp/combined.pem &&               socat OPENSSL-LISTEN:3000,cert=/tmp/combined.pem,verify=0,fork,reuseaddr TCP:openhamclock:3000"      restart: unless-stopped 

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:

find /app/dist -name "*.css" -exec sh -c 'echo "div[style*=\"whatsNewSlideIn\"], div[style*=\"backdrop-filter\"] { display: none !important; }" >> {}' \;

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

1. Log in to your PiSignage Admin Panel.
2. Navigate to Assets > Add > Weblink.
3. Fill in the details:
   • Name: OpenHamClock
   • Link Address: https://<YOUR-HOSTNAME>:3000/?kiosk=true
4. Click Save.

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

1. Go to Playlists and add your new “OpenHamClock” asset.
2. Set the Duration: Set this to 0 for a permanent display, or a high number (like 300 for 5 minutes) if it’s part of a rotation.
3. Go to Groups, select your player, and deploy the playlist.

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.

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?

Two-Factor #Authentication (2FA) typically combines a password with a code, whereas Multi-Factor Authentication (MFA) adds more layers, such as biometrics (fingerprint/face) or hardware tokens. Read MFA vs 2FA: What's the difference https://windowspost.com/2fa-vs-mfa/

Key Differences Between 2FA and MFA

Number of Factors: 2FA limits authentication to two layers (e.g., password + OTP), while MFA can incorporate three or more (e.g., password + OTP + fingerprint).

Security Level: MFA generally provides superior security against sophisticated attacks because it relies on multiple independent factors.

Complexity & UX: 2FA offers a more streamlined user experience with fewer steps. MFA may cause more user friction due to additional login steps, but it enhances security.

Flexibility: MFA offers greater flexibility, allowing organizations to adopt adaptive, risk-based authentication, while 2FA is a fixed two-step process

2FA Example: Entering a password (knowledge) and a code texted to your phone (possession).

MFA Example: Entering a password, a code from an app, and using a biometric scan (fingerprint or face)

An OTP (One Time Password) is valid for exactly 30–60 seconds.
Even though no one stores it anywhere. So, how does the server verify it without ever saving it?

Well, that’s usually called a Time-based One-Time Password (TOTP).

Here’s how it actually works:

• A secret key is shared between your device and the server (only once)
• Both use the current time window (like 30 seconds)
• And a secure algorithm (HMAC)

Using these, both sides generate the same OTP independently.

✅ No storage
✅ No database lookup
✅ Just math + time

When you enter the OTP, the server simply regenerates it and checks:
👉 “Does this match?”

That’s how your OTP is verified… without ever being saved. 🔐

High CPU usage in Windows 11 usually means a process is using more CPU cycles than it should. It could be due to excessive background apps, pending Windows updates, corrupted system files, or high-resource processes like antivirus scans and indexers.

Fixes for High CPU Usage (Windows 11)

Restart Your PC: This is the quickest way to clear stuck processes and memory.

Use Task Manager: Press Ctrl + Shift + Esc, find processes with high CPU usage, right-click them, and select "End task".

Disable Startup Apps: In Task Manager, go to the "Startup apps" tab, right-click unnecessary apps, and select "Disable".

Update Windows & Drivers: Go to Settings > Windows Update to ensure you have the latest performance patches.

Check Power Settings: Search for "Choose a power plan" in the Control Panel, and select "Balanced" or "High Performance".

Scan for Malware: Run a full scan with Windows Defender, as viruses can cause high CPU usage.

Disable SysMain (Superfetch): Search for "Services," find "SysMain," right-click to stop it, which can reduce background resource usage.

Disable High Precision Event Timer: In Device Manager, find "High precision event timer" under System Devices, right-click, and disable it

Resetting Windows 11 (using the Reset this PC feature) reinstalls the operating system and fixes performance issues by reverting settings to their defaults. You can choose to either keep personal files (removes apps/settings) or remove everything (full factory reset). It generally takes 30 minutes to one hour, depending on system configuration.
