I’ve been working with Azure on a day-to-day basis for the past five years. I never took any official courses—everything I learned came from real client requirements and hands-on problem solving. One day, I started wondering: How strong is my Azure knowledge really? That’s when I decided to take an Azure certification exam to test myself. The last IT certification I earned was back in 2003 (Windows Server). It felt like the right time to renew myself professionally. Reality Check I started immediately with the Microsoft practice test. Out of 50 questions, I could confidently answer only about 10. That was a wake-up call. WhenRead More →

If you want to provide authentication for your App Service without writing a single line of code, you can turn on the Authentication in App Service configuration. When you turn on this option, Azure will verify the users before sending the traffic to the application. There is a challenge when it comes to monitoring, if our monitoring tool can’t pass this authentication, we’ll not be able to monitor this application. There are many case the application is not working, but Azure still ask the user to login before seeing the errors. Here is a simple script that can authenticate using a principal account. #!/bin/bash #Read More →

The Oil Pressure Switch is designed to detect any issues with your car’s oil system. Many online videos and posts only show one type of switch—the normally closed (NC) type—but in reality, there are two types: Normally Open (NO) Switch: Closes the circuit when oil pressure is low, turning on the warning light. Normally Closed (NC) Switch: Opens the circuit when oil pressure is low. The challenge is that you might not know which type is installed in your car. That’s why it’s important to test both scenarios: a normal test and a test using an air blow. If you see the switch status changeRead More →

Initializing n8n process n8n webserver failed, exiting The fix is to add this line -e N8N_LISTEN_ADDRESS=0.0.0.0 In my case, the problem was that IPv6 was disabled in my kernel. Since at least version 1.107.4, the default listen address is ::. sudo docker run -it –rm \ –name n8n \ -e GENERIC_TIMEZONE=”America/New_York” \ -e TZ=”America/New_York” \ -e N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=false \ -e N8N_RUNNERS_ENABLED=true \ -e N28N_SECURE_COOKIE=false \ -e N8N_METRICS=true \ -e N8N_LISTEN_ADDRESS=0.0.0.0 \ -e QUEUE_HEALTH_CHECK_ACTIVE=true \ -v ./n8n_data:/home/node/.n8n \ docker.n8n.io/n8nio/n8nRead More →

I recently bought a Honda H3001 riding mower, it was sold for parts. I have tried to fix everything, but the most challenges for me is the deck belt. I bought 2 deck belt and i could not install it in the first place because none of them fit perfectly. They are all 5/8in x 72, after many tries, days, this is what i figured out. The correct part # is 76181-763-A02 or any equivalent 5/8in x 72 in deck If your belt is too tight or too loose, adjust the tension belt. When you install the deck, install the belt first, connect the beltRead More →
