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 ...

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_...

Laravel validation rule 'Exists' with secret feature.

-
In this post, I wish to share one secret feature of laravel validation rule 'Exists'. If you have worked with laravel and familiar with laravel validation, you must know what does 'Exists' rule checks. If not let me give here a brief about this. In simple words,  'Exists' rule check if a record exists in the given database table with column value matching with the provided input value. Format: 'exists:table,column' So this is what as mentioned in laravel documentation too. So looking at the format we understand that this rule is to validate given input value by check if any records exist or not for that particular input value matching with the given column values of the table. Let's take an example. 'booking_id' => 'exists:bookings,id' Here we are validating provided booking_id with exists, if records exist in bookings table matching the column id (in most of the cases but can use any column as per your requirement.) ...

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...
