Recently, I upgraded my system OS from ubuntu 20.04 LTS to 22.04 LTS which I have been waiting for a long-time. It seems all goes well until I faced issues while sharing my screen over MEET or ZOOM meetings. I searched for solutions and found most of the solutions on Stackoverflow suggesting to disable the Wayland display feature and working with X11 which was used in earlier versions of Ubuntu OS. But disabling the Wayland UI scheme is not the correct solution,  because will slow down the system because the Wayland display feature is very fast in performance as compared to Xorg X11. Moreover, the Wayland display feature is more secure than Xorg X11 while providing access to the system. Actually, it is not a problem with Ubuntu OS itself. It is problem with the browser hasn't developed a feature compatible with Wayland security protocols. If anyone is facing problems with screen sharing because of OS upgraded to ubuntu 22.04, Here is the solution (without disabling the Wayla...

When talking about securing the Laravel application, we might also want to restrict IP address to access our application, especially when we have Laravel setup as a Backend server providing data through APIs or web services. As of today, you might find no. of Laravel package providing IP address restriction functionality but I found it does not make any sense to install a package when it is achieved through only One class.  Yes! we can just do this with a simple middleware class.  Let me explain to you little details on how we can achieve it using the Middleware class. First, let's create a middleware class using the Laravel artisan command: php artisan make:middleware RestrictIPAddress It will create a new class in your Laravel project under the ` app/Http/Middleware ` directory. It will have a default empty method handle(), where you have to write your logic. Logic is simple, you just have to get the IP address from where the request is coming. here is the method...

This is something I experienced and observed in my life till that time. I strongly believe - Trust, Honesty, Loyalty and Forgiveness are essential 4 elements that strengthen the relationship. How? let me explain. Trust Trust is a very essential element of any relationship we build. A relationship can't go long without trust.  When you trust your partner or one you are in relation with, it makes you overlook or avoid the things that others used to say about them.  You never fall into distrust easily by listening to others. Honesty If you are honest with your partner or someone you are in a relationship with, you must always tell truth about whatever happens in the relationship. Even if something wrong happens un-intentionally and we speak upon truth honestly, most of the time front person forgives us for knowing the truth and our honesty about the relationship. Loyalty If you are loyal to your partner or someone you are in a relationship with, you must not do anything wron...

Our Parents in old age learn to adopt changes in life faster than us. Still, we thought they are rigid and old thoughts people. In modern times we are more intelligent to understand the situation and time changes. But actually, we are not. It's a kind of myth. Our old parents are more intelligent to understand the changes in life.  Most of the time I saw our parent silently accepts the change even if it doesn't suit them, because they have seen the world evolving, and new thing happenings more than we have seen in our life.  And they know either way they have to accept it (change) to keep going on with the world. On other hand, we found difficult to adopt a change most of the time and we keep ourselves to be the same as we are.

Papertrail is basically a log management tool used for catching Heroku systems and build but not limited to. It has been useful because on Heroku we can check live logs and can't check logs for the previous requests except for logs for the deployment process. So below are some of the key features which paper trail providing us: Recording the system logs live and we can also look into the logs of the past (from n no. of days up to a year) based on the plan we choose. It allows searching past logs by date-time, string or regex. It also allows us to configure alerts (emails, Slack) for a specific type of request failure response like time-out, system error or even request taking time more than a particular limit. It allows us to set filters for logs to save or not to save. Some advantages we seek from Papertrail are: Heroku adon is available with one-click installation like other adon. Fast and easy search interface. Able to store long time period logs history (up to 1 year) Custom al...

If you are using Heroku and Postgres adon in your project, by the time you may want to upgrade or downgrade Heroku Postgres adon plan based upon your project's database size decrease or increase with time. Although you can follow Heroku documentation for the purpose: Changing the Plan or Infrastructure of a Heroku Postgres Database But I wish to introduce you to another way to upgrade or downgrade the Heroku PostgreSQL Database adon plan. In this process we have 3 steps to follow: 1. Add additional Heroku Postgres adon with the desired plan (you want to switch) using the below command:      heroku addons:create heroku-postgresql:adon-plan --app your-appname Where `adon-plan` can be replaced with the desired plan from the plan list and `your-appname` with your application name. 2. Now copy your database from the old Postgres adon to the newly added Postgres adon.           heroku pg:copy HEROKU_POSTGRESQL_MAUVE_URL HEROKU_POSTGRESQL_PINK_URL ...

You may have read differences between PostgreSQL datatypes JSON and JSONB. If not, let see the difference between both theoretically and practically. Although, both json and jsonb are types of PostgreSQL JSON datatypes and accepts almost same format as input values i.e. json. But still there are some difference which one must know to efficiently use or can choose from both json and jsonb.  The main different is how they actually store data; the json data type stores input value as it is but  jsonb stores value in a decomposed binary format which lead to difference in  efficiency .  Jsonb is slower as compare to json while saving the input values because of converting json values to binary format before saving. Jsonb fast in processing the data because no re-parsing needed as compare to json datatype which needs processing function to re-parsing on every execution. Few other differences between json and jsonb are: Jsonb supports indexing which is advantage over j...

Today I am going to share, How we can use Laravel validation rule `unique`. If you have worked with laravel and familiar with laravel validation, you must know what does 'unique' rule checks. If not let me give here a brief about this. In simple words, It is similar to a unique key constraint applied to a column in the database table. 'Unique' rule check there is no similar value exists in the given database table column, to value matching with the provided input value. The general format of the rule is: unique:table //when input name is similar to column name OR unique:table,column OR unique:Model,attribute Examples: 'email' => 'unique:users' //here users is table name OR 'email' => 'unique:c,email_address' //can give custom column name. OR 'email' => 'unique:User,email'  //here User is a model class This is a very simple usage ...
