Prioritize your tasks: Not all tasks are created equal, so it's important to prioritize your work. Figure out which tasks are the most important and tackle those first. This will help you stay focused and avoid getting bogged down by less important tasks.

Stay organized: A cluttered workspace can lead to a cluttered mind, which can make it difficult to focus and be productive. So be sure to keep your workstation organized and tidy. This will help you stay focused and on top of your work.

Automate where you can: Automating tasks can save you a lot of time and effort. Look for opportunities to automate repetitive tasks, such as code formatting or linting. This will free up more time for you to focus on more important tasks.

Learn from others: Finally, don't be afraid to ask for help or learn from others. Whether you're stuck on a problem or just looking for ways to improve your workflow, other developers can be a valuable resource. So be sure to ask for help when you need it and seek out opportunities to learn from your peers.

By following these tips, you can boost your productivity and get more done as a developer in 2023. Stay focused, stay organized, and don't be afraid to seek out new tools and techniques to help you work more efficiently.

Thalhatou Yahya — Thu, 17 Dec 2020 09:10:04 +0000

1.INTRODUCTION

In this tutorial, we are going to show you how to install MongoDB on Windows 10 operating system .Lets start by briefly understanding what MongoDB is all about.

History of MongoDB

MongoDB was created by Eliot and Dwight (founders of DoubleClick) in 2007, when they faced scalability issues while working with relational database. The organization that developed MongoDB was originally known as 10gen.
In Feb 2009, they changed their business model and released MongoDB as an open source Project. The organization changed its name in 2013 and now known as MongoDB Inc.

What is MongodDB?

MongoDB is a NoSQL database. There are different types of NoSQL databases, so to be specific :
MongoDB is an open source, document oriented database that stores data in the form of documents (key and value pairs).

What is a document?

If you came from a relational database background then you can think of them as rows in RDBMS.

2.INSTALLATION

###STEP1
Go to MongoDB official download Page following this link select your operating system as windows and click download as shown in the screenshot below.

A .msi file like this mongodb-windows-x86_64-4.4.2-signed will be downloaded in your system. Double click on the file to run the installer.

Step 2:

Click Next when the MongoDB installation window pops up.

Step 3: Accept the MongoDB user Agreement and click Next.

That’s it.Wait for it to install Click Finish once the MongoDB installation is complete.

3.Configuration

Step1

Go to the server path of mongoDb in Program Files and copy the bin folder path as shown below on the screenshot

Step 2

Now we need to add the path we copy to the system environment variable path so we can access mongoDB from our windows terminal directly and carry out operations.lets do this as show on screenshots below

Lets click on Environment Variables and Click on Path Variables

click on new

Now lets paste the path to the bin folder we copied earlier to the new variable path we created

Now to check if its working we are going to run our command prompt as an administrator and run the command mongo --version and if you see as shown on the screenshot below then its working.

Thanks for reading see you next time.

How to Install MySQL Workbench and XAMPP on Mac

Thalhatou Yahya — Thu, 19 Nov 2020 09:04:34 +0000

lets start by installing XAMPP .
Procedures :
Download the correct version of XAMPP
Run the installer with the default options
Launch XAMPP
Start the services.
Go to Apache Friends and download the correct version of XAMPP.
For this tutorial, I'll be using XAMPP 7.2.28 for OSX.

After Downloading
Once you open the .dmg file you'll see a window, as follows.

To install the XAMPP on your macOS machine, simply double-click the application inside the installer window and it'll open the main installer window for XAMPP.

Just click Next, Next, and Next until it installs. No need to change any settings in the installer.

Run XAMPP
To run XAMPP, go to Applications Folder on macOS, locate XAMPP Folder and inside that folder, locate an app manager-osx and run it.
Now, it's time to use XAMPP but before we can do that, we need to activate and run its services which we need to run the servers.
Once the application is open, go to "Manage Servers" tab and click on "Start All" button.

Wait for it to give all the green lights and then, it a go.
You can access the servers on your browser through localhost
Now its time to install MySQL Workbench.
Lets start by understanding briefly what is MySQL and Xampp.
What is MySQL?
MySQL is powered by the oracle corporation, and it is an open-source relational database management system (RDBMS) that works on many platforms.
It uses a client/server model, which means the database typically runs on a server.
It provides multi-user access to support many storage engines and not only these, but it also offers various other features like it provides good connectivity so you can connect with multiple databases and clients.
MySQL uses Structured Query Language(SQL) to define, update, and query the database.
It provides a low total cost of ownership and It is very flexible and scalable.
It provides various other tools such as MySQL workbench.
It is very robust and secure.

What is MySQL Workbench?
MySQL Workbench is nothing but a visual or Graphical
tool/IDE by which you can work with MySQL servers/databases and perform database connectivity.
It is a dashboard that enables you to prepare models, perform server administration, monitor and configure your data and also perform data migration.
It allows you to connect with the MySQL database. It makes working on the databases a lot easier because it has all the tools included to be able to build databases, tables and also administrate the database itself, for example, you can add users manage their rights.
It allows you to do queries and other things.
MySQL Workbench is available for all major operating systems like Windows, Linux, and Mac Os X.But our main focus here is to install it on Mac .
lets start by downloading MySQL Workbench from this link

Select the operating system as macOS and then click on the Download link to download the DMG archive file.
As soon as you click on the download link, you will be redirected to another webpage, and it will ask you to Login or Sign Up to the oracle web account.
But if you are only concerned about downloading the file, then click on the link “No thanks, just start my download” as shown in the below figure.

After you have successfully downloaded the MySQL installer MSI file in your system, Now you need to install it in your system.
Double click on the installer file, and you will see that the setup wizard of MySQL Workbench will open.
Click the Next button to proceed

Wait for a while until MySQL Workbench is copied to the Applications, and MySQL Workbench will be successfully installed in your system.
To start MySQL Workbench, go to Finder>>Applications and then double click on the MySQL Workbench icon to open it.
On opening for the first time, you will see something like this user interface, as shown in the figure below

To connect MySQL Workbench with MySQL Server, click on the location highlighted with the red arrow, as shown in the above figure.
As soon as you click on it, a dialog box will appear, and it will ask you to fill the password.
This is the same password that you have given during the installation process of MySQL Server, so fill in the correct password and click on the OK button.

Essential extensions for Angular developers

Thalhatou Yahya — Mon, 05 Oct 2020 11:59:24 +0000

Visual Studio Code (more casually known as VS code) is a lightweight but powerful cross platform open source code editor that runs on your desktop. With built in support for debugging, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git. I quickly fell in love with the editor the more I used it to build my projects.

Another reason for its broad popularity is the various extensions available in the marketplace that enrich the development workflow. Today we are going to be looking at Angular Essentials extension pack for angular developers and some of the extensions included in this pack.
lets start by navigating to the Extension Menu of vs code and Search for the Angular Essentials keyword and click on the install
button.

This Angular Essential pack comes with 12 extensions to help angular developers boost their workflow and productivity some of them include.

1.Angular TypeScript Snippets
The Angular Snippets extension contains a collection of TypeScript and HTML code snippets for various Angular artifact, such as components,root app component,module,pipe,404 route path etc.
note
All available Angular snippets start with the a- prefix.

2.Angular Language Service
The Angular Language Service extension is developed and maintained by the Angular team and provides code completion, navigation,Go-to navigation and error detection inside Angular templates and its part of the angular essentials extension pack.To see some of the powerful capabilities of the extension, let's have a look at the code completion feature. Suppose that we want to display a new property called lead in the template of AppComponent. We can set this by defining the new property in the component class.

then Start typing the name of the property in the template. The Angular Language Service will find it and suggest it for you automatically.

3.Nx Console
Most of the time developers want to concentrate on delivering top notch Angular applications instead of trying to remember the syntax of every CLI command they want to use so Nx Console is an interactive UI for the Angular CLI that aims to assist developers that are not very comfortable with the command-line interface (CLI) or do not want to use it at all.To used the extension all you have to do is click at Nx console icon at the vs code menu and select your workspace and your good to go.

4.Material icon theme
VS Code initially comes with some built-in set of icons that it uses to display different types of files in a project. This extension provides additional icons that conform to the Material Design guidelines by Google.
Using this extension, you can easily spot the type of Angular files in a project, such as components and modules, and increase developer productivity, especially in large projects with lots of files.

NB
You need to reload VS Code after this extension is installed for the icon changes to take effect.

5.TSLint
TSLint is an extensible static analysis tool that checks TypeScript code for readability, maintainability, and functionality errors by applying a set of rules. These rules are defined in the tslint.json configuration file, which can be found in the root folder of an Angular CLI project. It is maintained by Microsoft and must be installed separately since its not part of the essential pack.

6.Peacock
Peacock vs code extension helps you to Quickly identify each of your Visual Studio Code instances using your favorite colors and its part of the Essential extensions for Angular developers as seen below.its very import when your working with multiple code instances (separate vs code windows with different part of the projects)

7.EditorConfig
VS Code editor settings, such as indentation or spacing, can be set at a user or project level. EditorConfig can override these settings using a configuration file called .editorconfig, which can be found in the root folder of an Angular CLI project. You can define unique settings in this file according to your project requirement and all your team Members can follow this configuration to ensure the consistency of the coding style across your team.

8.npm
This extension supports running npm scripts defined in the package.json file and validating the installed modules against the dependencies defined in the package.json.
Notice The validation is done by running npm and it is not run when the modules are managed by yarn.

Other extensions in the pack include
Debugger for Chrome
Debug your JavaScript code running in Google Chrome from VS Code.
ESLint
Prettier - Code formatter
Winter is Coming Theme
