Suggested January 2024 Linkedin Suggests 4 Types Of Posts To Share Amid Covid

As activity on LinkedIn ramps up during COVID-19 lockdowns, the company has published tips on what businesses should be posting.

Unsurprisingly, there has been a dramatic shift in the past month when it comes to the content people are interested in reading about on on LinkedIn.

In January and February, the top two hashtags on LinkedIn were #marketing and #leadership. So far in March, the top two hashtags are #coronavirus and #COVID-19.

The number of articles about coronavirus increased by 17-times on LinkedIn from February 1 and March 17.

Remote working

Social distancing

Crisis management

Business continuity

Online learning


and more

Searches for “remote working” alone tripled on LinkedIn Learning in the month of March.

To keep up with this sudden shift in user interests, here’s what LinkedIn suggests posting about.

What to Post on LinkedIn During Lockdowns Share Your Experiences

LinkedIn recommends sharing personal stories, as they can inspire and help others who are going through the same thing.

As an example, try composing a post by answering the question “what really helped me?”

In answering this question you can approach it like a conversation with a colleague or friend discussing what your new work day looks like.

Did you recently have a video call that would have otherwise been an in-person meeting? Share that experience along with insights you gained from it.

Conversely, you can create a post asking others to share their experiences.

Asking a question like “how do I boost team morale?” can encourage others to share their unique insights and contribute multiple points of view for others to learn from.

Discover & Comment On Relevant Conversations

LinkedIn recommends searching through hashtags to find information and conversations on topics that are interesting to you.

Be Yourself

You don’t always have to post about work-related topics, LinkedIn says.

In fact, some of the most successful posts come from professionals who discuss topics such as:

Lessons learned in their personal lives

Showing appreciation for their team

Sharing words of encouragement

Spreading kindness

And so on

Above all, don’t overthink it, LinkedIn says:

“When posting on LinkedIn, don’t overthink it. The key is to be genuine, which makes you more approachable and better reflects who you really are.”

Share Your Thoughts on (Trusted) News Stories

Staying informed and sharing the latest news from trusted sources is another way to foster engagement and conversation with your LinkedIn community.

LinkedIn notes that its team of editors are working to surface trusted news featuring reliable updates from experts including the World Health Organization and the Centers for Disease Control and Prevention.

Still Unsure?

If you’re still unsure of what to post about on LinkedIn during this time, here’s what you need to keep in mind:

“… if there’s a challenge you’re facing, you can rest assured that others are probably facing it as well. Better yet, there are also people out there who have overcome it, so don’t hesitate to ask your community for help if you need it.”

Guide To Types Of Php Annotations With Examples

Introduction to PHP Annotations

PHP annotations are basically metadata which can be included in the source code and also in between classes, functions, properties and methods. They are to be started with the prefix @ wherever they are declared and they indicate something specific. This information they provide is very useful to coders, helpful for documentation purposes and also an IDE may use this to display certain popup hint kind of things. The same annotation can also be used for other purposes besides validation such as to determine what kind of input needs to be given in a form and also for automation purposes. There are various kinds of annotations like the @var and @int types which can be used for specific uses as their name itself suggests.

Web development, programming languages, Software testing & others

Syntax class Example { public $new; }

Annotation is @var here and whenever it is encountered just before the piece of any code (public $new here for example) it indicates that the $new is to have a value of type integer as told by the annotation.

class Example { public $shop; }

Annotations can also be used for specifying the range where it displays the maximum and the minimum values that are to be accepted as integer values for the function and the label gives the purpose of this function.

Types of PHP Annotations

Given below are the types:

1. Built-in Annotations

There are 2 built-in functions in annotations which are as follows:

a. Compiled: This annotation indicates that if the method/function should be JIT compiled or not. It is also a function scope type of annotation.

b. SuppressWarnings: This is another built-in annotation which means that any warnings thrown as part of the execution of the succeeding code below it must be suppressed.

2. Meta Annotations

These are those type of annotations which can be used to apply for other annotations. They are used for configuration of annotations.

a. @Annotations

There is a kind of annotation classes which will contain @annotation.


[@Annotation] class MyAnnoExample { }

b. @Target

As the name suggests, this annotation indicates those types of class elements or a method upon which the annotation will be applicable.

Property annotation is just before the property class declaration.

Class which is allowed before the declaration of class.

Function is declared before the function declaration.

Method annotation allows proceeding the method declaration.

Annotation is allowed for proceeding to declaration of annotation class.

c. @Repeatable

This annotation means that it may be repeated any number of times when being used.

d. @Inherited

This can also be used on the other user defined annotation classes as a meta-annotation. These inherited annotations are automatically inherited to the respective sub-classes when they are used upon a superclass.

3. Custom Annotations

These are very similar to declarations of the normal class. Each element of the annotation type is defined by each of the property declarations.

Examples of PHP Annotations

Given below are the examples mentioned:

Example #1


[@Annotation] [@Target("class")] class MyAnnoEx { [@Required] public string $prop; public array $arrayProp = []; public embedAnno $embed; } [@Annotation] [@Target(["class", "annotation"])] class embedAnno { } [@Annotation] [@Target("property")] class propAnno { } @Annotation @Target("method") class methodAnno { public string $val; public function __construct(string $val) { } }

This is just a basic example showing the usage of all the different types of annotations which are shown above. All the ones in the example like embed annotation, property annotation, method annotation are custom annotations.

Example #2

<?php /** * @Replace(“exmaple”, “for”, “annotation”) */ class MyNamedComponent { } echo str_replace(“First”, “Second”, “First Example”);


In this example we are naming the annotation as replace since the below code represents the usage of string replace function which is str_replace, an inbuilt function of PHP. Using this function, the first parameter passed in the function is replaced by the second one.

Example #3


<!–Declaring First name for the form First_Name: <!–Declaring Last_Name for the form Last_Name: <!–Declaring Location for the form Stay location: <!–Declaring EMAILID for the form EmailID: <!–Declaring Password for the form Password: <!–Declaring Password for the form Gender: <input type=”radio” value=”Male” <input type=”radio” value=”Female” <?php if(example($_POST[‘confirm’])) { if(!example($error)) { } }


In this example, we are showing annotations in combination with the form validation in PHP. Using annotations we are labeling all the parameters which are required as input parameters to the form such as first and last name, email, location and password.


With the above examples we have noticed how annotations are a powerful tool to use and express metadata about our methods, classes or properties. We have also seen how to combine different kinds of annotations to declare workers who will perform certain tasks by writing some metadata about them. This makes them easy to find and gives actual information on whether or not they can be used.

Need And Types Of C++ Formatter

Definition of C++ Formatter

Start Your Free Software Development Course

Web development, programming languages, Software testing & others

Need of C++ Formatters in Source Code

Let us understand the need for C++ formatters with the help of an example:


using namespace std; intmain() { int num1, num2, add; cout<< “Enter the first integer”; cout<< “Enter the second integer”; add = num1 + num2; cout<< “The result is ” <<add ; return 0; }

The above code is the simple addition of 2 integer numbers. But how it is written makes it very uneasy or difficult to understand. There is a need for proper indentation and required spaces in the code. Code after ‘{‘ should be written and should be indented properly to show that the required block of code is a part of it. It should be formatted as given below:

using namespace std; intmain() { int num1, num2, add; cout<< “Enter the first integer”; cout<< “Enter the second integer”; add = num1 + num2; cout<< “The result is ” << add; return 0; }

Types of C++ Formatters

There are a lot of formatters / beautifiers available in the market. Let us understand some of the commonly used formatters in detail:

1. Clang-Format

Clang format is one of the most popular open-source formatters used to format C, C++, and Objective C source code. It automatically formats the C++ code and helps better understand the code. To format the source code automatically according to Electron C++, we need to run the following command:

clang-format -i

Users can also perform the formatting of code according to the specific requirements (other than the one available by default) by inserting the style in ‘.clang-format’ file or using the option -style = “{key:value, ….}”.

2. PrettyPrinter 3. Jindent

It automatically indents the code according to the syntax and correct coding conventions, which helps in finding the bugs in the code and saves time. One of the cool features of Jindent is that it provides a plugin for almost all popular IDEs like Visual Studio, Eclipse, Netbeans, etc so that it can be used easily by the programmers/ testers working on them. It allows its invocation from the shell scripts. Jindent provides support for all the Operating systems is it Windows, Mac, or Linux. Jindent is very user-friendly as it provides the GUI so that the user can perform actions like formatting settings, changing the environment variables, etc, very easily.

4. Highlighter

It is very user-friendly and hence pretty simple to use. Users must copy the source code in the desired text field, choose the C++ language, and Style dropdown to have the required formatting. It provides other interesting features as well as one can also choose to see the line numbers on the left side of the code and can directly insert the source code in the HTML page without adding any external CSS and JavaScript file to it.

Conclusion – C++ Formatter

The above description clearly explains the various formatters/beautifiers available in the market used to format the source code of C++ programs. Proper formatting and indentation are a must while working on real-time projects as it helps in a clear understanding of code and finding the bugs and hidden errors easily, especially the syntactical ones. It helps the maintenance team also to maintain the code properly and proceed further accordingly.

Top 5 Types Of Oracle Constraints

Introduction to Oracle Constraints

Oracle Constraints clause provides data integrity to the data that is being used by the application from the database by applying certain rules or conditions on a column of a database table which will define a very basic behavioral layer on the column of that particular table to check the sanctity of the data flowing into it like NOT NULL constraint on the column will not allow any data of that column to be NULL as it will not allow users to insert NULL data into the column.

Hadoop, Data Science, Statistics & others

Types of Oracle Constraints

Oracle has multiple types of constraints for multiple purposes. In this section, we are going to go through the different types of constraints in Oracle.


If we just add a column, by default the column is allowed to hold NULL values but in case there is a requirement that the column should not hold any NULL values. We can use NOT NULL constraint on that particular column. This will enforce the column to always have a value and it will not allow any NULL record to be added in the column. We will add NOT NULL constraint using both CREATE TABLE and ALTER TABLE constraint. We will create a table STUDENT with student_id, LastName and zfirstName columns having NOT NULL constraint.

Let us look at the query.



Let us now the query in SQL Developer and look at the result.

As you can see from the above screenshot we have successfully created the table with NOT NULL constraints. Let us now look at the ALTER statement query to add NOT NULL constraint to the age column of STUDENT TABLE.



Let us now run the query in the SQL developer.


As we can see from the output the column AGE has now NOT NULL constraint added to it.


This constraint in Oracle ensures that all the values of the column are different from each other and there are no duplicates. We will again use two examples to understand. First using the CREATE statement and then using ALTER statement. We will create a table STUDENT with student_id having UNIQUE constraint.

Let us look at the query using the CREATE TABLE statement.



Let us now run the above query in SQL developer.


As we can see UNIQUE constraint has been added to the columns of the table. Now let add a UNIQUE constraint to age column using ALTER TABLE statement.



Let us run this query in SQL developer.


As we can see the table student has been successfully altered.


Primary key constraint uniquely describes each value of a column. No duplicates or NULL value is allowed. One important point is that a table can have only one primary key which in itself can be a combination of single or multiple fields.

We will first create a table ‘student’ with student_id as the primary key using the CREATE TABLE statement.




As we can see the Table STUDENT has been successfully created. Let us now add primary Key using the ALTER TABLE statement to student_id column after the STUDENT table has been created.


ADD PRIMARY KEY (student_id);

Let us now run the query in SQL developer and check the result.


As we can see the table STUDENT has been successfully altered.

4. FOREIGN KEY Constraints

A foreign key is a field which refers to the PRIMARY KEY of another table and the table which actually has the foreign key is called child table. Let us now create a table order which we has student_id column as a foreign key refrencing student_id column of student table using CREATE TABLE statement.



Let us now run the query in SQL developer and look at the result.


As we can see the orders table has been successfully created. Now we will use the ALTER TABLE statement to add a foreign key to the student_id column of orders table.


Let us run the query in SQL developer and look at the result.


As we can see the table orders has been successfully altered.

5. CHECK Constraint

The CHECK constraint is used to limit the value of the range that can be placed in a column. In case we want to restrict certain values in a column or a table we introduce the check constraint. We will introduce the CHECK constraint using both CREATE TABLE and ALTER TABLE statement.

We are going to create a table student with age column having a check constraint.



Let us run the query in SQL developer and look at the result.


As we can see the table has been successfully created with the CHECK constraint. Let us now add CHECK constraint on the same column after the table student has been created using ALTER TABLE statement.


Let us now run the query in SQL developer and see the result.


As we can see the CHECK constraint has been added to the table.
