How are AI tools helping solve real, complex, and time-consuming problems faster?

-
Nowadays, almost everyone is either using AI tools or thinking about incorporating them into their daily work. At the same time, many professionals are still hesitant, worrying that AI might replace their jobs. While those concerns are understandable, I believe the bigger risk is ignoring these tools altogether. From my experience, AI isn't replacing engineers—it is helping engineers work faster and focus on solving more meaningful problems. Like any other tool, its value depends on how effectively we use it. The more we learn to collaborate with AI, the more productive and efficient we can become. Here are two real examples from my recent work where AI tools helped me solve complex and time-consuming engineering problems significantly faster. AI helped me audit and upgrade my project's tech stack by checking dependency compatibility and flagging version-specific issues in advance. Instead of manually reviewing every package and verifying the latest compatible versions, I was ...

Solution for Screen Sharing not working on Ubuntu 22.04

-
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...

Laravel Middleware - Block IPs using Middleware class

-
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...

Differences between json and jsonb - JSON data type in PostgreSQL

-
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...

Laravel Validation - Unique rule with multiple column and condition.

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 ...

Using Virtual Columns in Laravel - Accessors and Appends

-
What are virtual columns?  While developing any web application sometimes we need virtual columns - columns don't actually exist in our DB table, but we drive them from other columns. Why we need them? For example, generally, we use first_name and last_name  in the  users table. But sometimes we also need user's complete name i.e. full_name . There is no benefit of saving full_name in user table if we have already first_name and last_name in the table OR even if we have full_name  as a column in our table then there is no benefit of saving first_name and last_name in the table. So in a scenario like this, we prefer to use the virtual column. Using Virtual Columns in Laravel Considering the first case, in Laravel to get virtual column i.e.  full_name  from the users table will have Accessors. Accessors are methods defined automatically called by Eloquent when select is called on that particular column. Let take an example here: To get full_...
