...in a database management system (DBMS), allowing transactions to run concurrently has significant advantages, such as better system resource utilization and higher throughput. However, it is crucial that these transactions do not conflict with each other. The ultimate goal is to ensure that the database remains consistent and accurate. For instance, if two users try to book the last available seat on a flight at the same time, the system must ensure that only one booking succeeds. Concurrency control...

“If I Look Like That, Maybe I’ll Be Enough” — The Lie We Keep Believing
I am writing to you not only as a concerned citizen but as someone who can no longer stay silent about the devastating impact body image culture is having on young people in our country.
Right now, somewhere, a teenager is standing in front of the mirror, eyes full of disappointment, asking themselves a question no child should ever have to ask:
“What’s wrong with me?”
Not because they’ve...

Re: When the world is ablaze, will we douse the flames or dare to speak There are moments in history when silence ceases to be neutral — it becomes an act of surrender. Today is such a moment.

We live in a world where young people are relentlessly told to “prepare for the future.” Yet, paradoxically, we are expected to do so with the very tools of that future forcibly stripped from us. I write to you not with the naive rebellion of a teenager desperate to cling to their phone, but with

Somewhere, right now, a teenager is standing in front of the mirror, eyes full of disappointment, asking themselves a question no child should ever ask:
“What’s wrong with me?”
Not because they’ve failed a test. Not because they’ve done something cruel. But because their stomach isn’t flat enough. Because their skin isn’t smooth enough. Because their body doesn’t look like the ones they scroll past, day
...Control Should Not Come at the Cost of Connection: The Case Against Banning Mobile Phones in Schools
By [Your Full Name]
4 June 2025
We live in a world where young people are constantly told to “prepare for the future.” Yet, paradoxically, the very tools that define that future — mobile phones — are being stripped away from us in schools. Banning mobile phones in educational settings is not an act of discipline; it is an act of denial. A denial of how we live, how we learn, and most crucially,
