macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.

Oracle SQL Developer Installation. Unfortunately Oracle doesn't make it easy to import a new colour scheme into SQL Developer, thus a little bit of hacking is required. Close SQL Developer. This is important. If you modify the scheme file while SQL Developer is open, your changes won't be saved. Oracle SQL Developer 19.2.1 Downloads, Mac OS X Installation Notes. This download does not include the Oracle JDK. SQL Developer supports either Oracle JDK 8 or 11. Ensure you have a JDK installed, if not, download here (For 64-bit Intel Macs, download Java for Mac OS X 10.5, Update 1.

All-new Interface

macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.

Widgets

Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.

Safari Extensions

With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.

The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.

Machine Learning

With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.

Mac Catalyst

Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.

User privacy on the App Store.

Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.

Tools and resources

Use Xcode 12 and these resources to build apps for macOS Big Sur.

I previously explained how to install SQL Server on a Mac via a Docker container. When I wrote that, SQL Server 2017 was the latest version of SQL Server, and it had just been made available for Linux and Docker (which means that you can also install it on MacOS systems).

In late 2018, Microsoft announced SQL Server 2019 Preview, and subsequently announced general release in late 2019. The installation process for SQL Server 2019 is exactly the same as for SQL Server 2017. The only difference is that you need to use the container image for SQL Server 2019 instead of the 2017 image. Here I show you how to do that.

Also, if you already have SQL Server 2017 installed, and you want to install SQL Server 2019 without removing the 2017 version, you’ll need to allocate a different port number on your host. I show you how to do that too.

Docker

The first step is to install Docker. If you already have Docker installed you can skip this step (and jump straight to SQL Server).

Docker is a platform that enables software to run in its own isolated environment. Therefore, SQL Server 2019 can be run on Docker in its own isolated container.

Install Docker
To download, visit the Docker CE for Mac download page and click Get Docker.
To install, double-click on the .dmg file and then drag the Docker.app icon to your Application folder.
Launch Docker
Launch Docker the same way you’d launch any other application (eg, via the Applications folder, the Launchpad, etc).
When you open Docker, you might be prompted for your password so that Docker can install its networking components and links to the Docker apps. Go ahead and provide your password, as Docker needs this to run.
Increase the Memory (optional)
By default, Docker will have 2GB of memory allocated to it. I’d suggest increasing it to 4GB if you can.
To do this, select Preferences from the little Docker icon in the top menu:
Then finish off by clicking Apply & Restart

SQL Server

Now that Docker has been installed and configured, we can download and install SQL Server 2019.

Download SQL Server 2019
Open a Terminal window and run the following command.
This downloads the latest SQL Server for Linux Docker image to your computer.
You can also check for the various container image options on the Docker website if you wish.
Launch the Docker Image
Run the following command to launch an instance of the Docker image you just downloaded:
Just change Bart to a name of your choosing, and reallyStrongPwd#123 to a password of your choosing.
If you get a “port already allocated” error, see below.
Here’s an explanation of the parameters:
-e 'ACCEPT_EULA=Y'
The Y shows that you agree with the EULA (End User Licence Agreement). This is required.
-e 'SA_PASSWORD=reallyStrongPwd#123'
Required parameter that sets the sa database password.
-p 1433:1433
This maps the local port 1433 to port 1433 on the container. The first value is the TCP port on the host environment. The second value is the TCP port in the container.
--name Bart
Another optional parameter. This parameter allows you to name the container. This can be handy when stopping and starting your container from the Terminal. You might prefer to give it a more descriptive name like sql_server_2019 or similar.
-d
This optional parameter launches the Docker container in daemon mode. This means that it runs in the background and doesn’t need its own Terminal window open. You can omit this parameter to have the container run in its own Terminal window.
mcr.microsoft.com/mssql/server:2019-latest
This tells Docker which image to use.
Password Strength
You need to use a strong password. Thiruvempavai lyrics in tamil pdf with meaning. Microsoft says this about the password:
The password should follow the SQL Server default password policy, otherwise the container can not setup SQL server and will stop working. By default, the password must be at least 8 characters long and contain characters from three of the following four sets: Uppercase letters, Lowercase letters, Base 10 digits, and Symbols.
Error – “Port already all
