CJP Founder Abhijeet Dipke Preventively Detained Ahead of ‘Lehra Do Tiranga’ March in Delhi

  Delhi Police on Friday preventively detained Cockroach Janta Party (CJP) founder Abhijeet Dipke at his residence, minutes before he was scheduled to lead a ‘Lehra Do Tiranga’ march at Central Park in Connaught Place. The detention was the second time in a week that the 31-year-old youth leader had been taken into custody amid protests demanding the resignation of Chief Election Commissioner Gyanesh Kumar. Police personnel had earlier visited Dipke’s place of stay in the Jhandewalan area and served him a notice under Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS). The notice cited prohibitory orders in force around Connaught Place and the absence of permission from the New Delhi Municipal Council (NDMC) for the proposed gathering. Officers warned that proceeding with the march without permission would violate the law. During the interaction, a police official told Dipke, “Aap New Delhi nahi jaa sakte. Hum aapko detain kar rahe hain” (“You cannot go to New Delhi. We ...

  The Solonik Protocol: A Forensic Deconstruction of the January 2026 Instagram Data Exposure and the Era of Weaponized APIs Part I: The Awakening – Anatomy of a Crisis 1.1 The Morning of Confusion The digital dawn of January 8, 2026, did not break with the thunder of a ransomware note or the catastrophic failure of critical infrastructure . Instead, it arrived with a persistent, annoying buzz in the pockets of millions of users worldwide. From New York to New Delhi, individuals awoke to a surreal and disconcerting notification on their screens: an official email from Instagram with the subject line, "Reset Your Password". 1 For many, this was initially dismissed as a glitch or a singular phishing attempt . But as the hours progressed, the volume of these notifications intensified. Users reported receiving not just one, but five, ten, sometimes dozens of identical emails in rapid succession. The source domain, security@mail.instagram.com, was undeniably legitimate, verified ...

CJP Leaders Saurav Das, Ashutosh Ranka Sent to Five-Day Judicial Custody

Image
  Saurav Das and Ashutosh Cockroach Janta Party (CJP) co-convenors Saurav Das and Ashutosh Ranka have been remanded to five days of judicial custody and lodged in Tihar Jail following their detention on October 13, after a group of activists entered the barricaded Jantar Mantar site and unfurled the national flag, according to the account provided. The incident has intensified debate over the right to protest, restrictions on public demonstrations in the national capital and the symbolism of the Tricolour. Police say the case concerns alleged unauthorised entry and violations of restrictions, while CJP leaders argue that the action is an attempt to suppress peaceful dissent. How the confrontation unfolded According to the supplied account, CJP members had planned a protest at Jantar Mantar against Chief Election Commissioner Gyanesh Kumar and alleged irregularities in the Special Intensive Revision (SIR) of electoral rolls. On October 10, Das, Ranka and CJP founder Abhijeet D...

Understanding Algorithms: Specification, Verification, and Performance Analysis

Fundamental Questions About Algorithms When presented with an algorithm designed to solve a particular problem, three fundamental questions naturally arise: What is it supposed to do? Does it really do what it is supposed to do? How efficiently does it do it? These three aspects are formally referred to as: Specification . Verification . Performance Analysis . Each of these aspects is critical to understanding and evaluating an algorithm, and their details are often problem dependent. Below, we delve deeper into each of these aspects, exploring their significance and the methodologies associated with them.   1. Specification The  specification  of an algorithm formalizes the problem it is intended to solve. It defines the relationship between the inputs and outputs of the algorithm, providing a clear description of what the algorithm is supposed to achieve. Key Points: Problem Formalization :...

The de-Broglie wavelength associated with a particle of mass m and energy E is h/2mE. The dimensional formula for Planck's constant is :

  The de-Broglie wavelength associated with a particle of mass m and energy E is h / 2 m E . The dimensional formula for Planck's constant is : Here is your right answer To determine the dimensional formula for Planck's constant, we will start by analyzing the given de-Broglie wavelength equation: λ = h 2 m E Here, λ is the wavelength, h is the Planck's constant, m is the mass of the particle, and E is the energy of the particle. First, let's derive the dimensional formula for each term involved: 1. Wavelength λ has the dimensional formula of length [ L ] . 2. Mass m has the dimensional formula M [ M ] . 3. Energy E has the dimensional formula of work, which is force times distance: MLT ML T [ E ] = [ F ] [ L ] = [ MLT − 2 ] [ L ] = [ ML 2 T − 2 ] . Now, let's rewrite the equation in terms of the dimensions: M ML T [ L ] = [ h ] 2 [ M ] [ ML 2 T − 2 ] Simplifying inside the square root: M M L T [ L ] = [ h ] 2 [ M ] [ M ] [ L 2...
