Google Chrome browsers have a weakness on memory systems, especially when multiple tabs are open, but the most popular browser in the world today got an upgrade to optimize both device battery power and memory use.

With Chrome’s latest version on the desktop, Google will present two new performance settings: Saver by memory and saver of energy. When used, Google said Chrome will consume up to 30% less memory and extend the battery from a device when it is running out.

They said “We’ll be rolling out both Memory Saver and Energy Saver modes over the next several weeks globally for Windows, macOS and ChromeOS,” Mark Chang, group product manager for Chrome.

When the new features arrive, they will run natively until users choose to turn them off manually or mark “important websites” to make them exempt from Memory Saver.

The features will be available with the release of Chrome 108, globally for Windows, macOS, and ChromeOS in the coming weeks.

今回はFlutterでAndroidのminSdkVersionとtargetSdkVersionを変更する方法を共有します。

android/app/build.gradleを開きます。そして、以下のコードを見つけます。

defaultConfig {
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
}

defaultConfig {
        minSdkVersion 16  
        targetSdkVersion 28 
}

minSdkVersionとtargetSdkVersionのところで変更したい値を変更することができます。

Today I would like to share the list of oauth libraries for NodeJS. Let’s take a look.

As all know, OAuth is an open-standard security framework that allows us to authorize different apps to communicate each other and gain access to protected resources.

Here are the popular and most used node js oauth libraries. Each list below can be clicked for more details by redirecting each github repository.

• jsonwebtoken
• node-oauth2-server
• simple-oauth2
• passport-oauth
• grant
• express-oauth-server

This is all for now. Hope you enjoy that.
