Turn Off Windows Sound Notification Banner

Operating System: Windows 10

In an earlier article I posted how to How to Disable Windows Volume Popup, but that required a small 300 KB program to be installed.

In my opinion the real-offensive element is actually the browser notification banner that gets attached to the media control popup. This is what I mean:

Both Chrome and Firefox notification banner attaches to this volume popup. Disable it like this:

Chrome

  1. In Chrome address bar, type chrome://flags/
  2. Then find the setting Hardware Media Key Handling and set it to Disabled.

Firefox

  1. In Firefox address bar, type about:config
  2. Then set media.hardwaremediakeys.enabled to false

Enjoy just the volume control bar without the ugly offensive banner!

Add Gitignore in Visual Studio

Objective: You have multiple Visual Studio projects (using the same technology stack) under a single git repository and you need to manually add a .gitignore file.

Instead of copy/pasting an existing .gitignore file, let Visual Studio generate it for you.

2 Steps to Add the .gitignore File via Visual Studio

  1. Inside Visual Studio, open your solution and click the tab “Team Explorer”
  2. Then click “Add” under Ignore & Attributes Files -> Ignore File
Steps to add .ignore file in the Team Explorer tab
After successfully adding the .gitignore file

This will add the .gitignore file in your root git repository folder. So you should not need to repeat the projects for other Visual Studio projects in the same folder (provided they are all using the same technology stack).

Dark Mode for Sumatra PDF

Windows: version 10
Sumatra PDF: version 3.2 64-bit

A dark mode for Sumatra PDF is really easy – you just need to tinker with 3 lines of code in the settings.

Why Use Sumatra PDF?

In my opinion, it’s the best PDF reader. It’s small in size, super-fast and doesn’t have any annoying cruft.

Why a Dark Mode (Night Mode)?

If you code for long periods of time, then it’s really great to have your code editor run in dark mode. This greatly reduces the strain on the eyes.

But let’s say you are also following along an e-book, maybe a PDF and you switch to Sumatra PDF. The default setting is black text on white background. Immediately your eyes are shocked with bright luminescent white light. It’s as if you were relaxing in a room with the lights switched off and suddenly someone walked in and abruptly turned the lights on.

As you are coding along you have to switch back and forth multiple times between your PDF reader and code editor. It can be really jarring for the eyes and nerves.

How to Enable Dark Mode?

In Sumatra PDF, click on the Menu -> Settings -> Advanced Options

This should open the SumatraPDF-settings.txt file in your text editor. Change the following 3 lines under the heading FixedPageUI:

TextColor = #eeeeee
BackgroundColor = #111111
GradientColors = #000000

TextColor changes the text color of the PDF document. Background color changes, well the background color of the PDF document. GradientColors will change the background window of Sumatra PDF.

You will get a confirmation box, hit the Apply button.

Directly Edit Config File my.ini

An alternative would be to directly edit the my.ini file and set the property:

default_time_zone = +8:00

In Windows 10, you can find the file here:

C:\ProgramData\MySQL\MySQL Server 8.0\my.ini

Set the JDK Path in GlassFish

GlassFish version: 5.1.0
Windows version: 10

Motivation

You may have several version of the JDK installed on your machine. By default you may be using JDK 11 or even 13, but GlassFish requires JDK 8.

Issue

Running asadmin generates the following error

Fix

Edit: ~\glassfish\config\asenv.bat
Assuming JDK 8 installation path is C:\Program Files\Java\jdk1.8.0_241

Add the line:

set AS_JAVA=C:\Program Files\Java\jdk1.8.0_241
