Remains: Challenging Patriarchy and Caste

With the rise of the Bharatiya Janata Party (BJP) and Hindu fundamentalism, Indian feminists criticize so-called development. Under globalization and economic success—especially in the IT sector—women and minorities are often neglected. Feminist resistance, therefore, targets more than just patriarchy. Indian society celebrates shakti (the divine feminine creative power), yet controls women through sharam (shame/modesty). A woman’s sexuality is tied to izzat (family honor), meaning women carry the responsibility for male behavior, female desire is policed, and patriarchal control is naturalized.

In The Remains of the Feast, Rukmini, a 90-year-old Brahmin widow, has lived a life shaped by:

• Gender

Processor & Memory Interface

Processor & Memory Interface: The maximum size of the memory that can be used in any computer is determined by the addressing scheme. For example, a computer that generates 16-bit addresses is capable of addressing up to 2¹⁶ = 65,536 (≈ 64K) memory locations. Machines whose instructions generate 32-bit addresses can utilize a memory that contains up to 2³² = 4,294,967,296 (≈ 4G) locations, whereas machines with 64-bit addresses can access up to 2⁶⁴ ≈ 1.84 × 10¹⁹ locations. The number of locations represents the size of the address space of the computer.

The connection between the processor and its memory consists of address, data, and control lines. The processor uses the address lines to specify the... Continue reading "Processor and Memory Interface: CPU Datapath, Registers & ALU" »

Keyword Research and Analysis

SEO keywords are the important words and phrases related to the developed website content. A list of keywords needs to be carefully chosen to optimize the search. Keyword Research and Analysis is an important part of Search Engine Optimization (SEO) as well as Search Engine Marketing. For Search Engine Marketing, one can pay for certain keywords. There are various online Keyword Planner tools (such as Google Ads Keyword Planner) to shortlist keywords. This is more useful to compare the cost of various keywords if the website designer opts for Paid Search Engine Marketing.

Futures Markets: Margins and Hedging

The Role of Margin Payments

Margin payments exist to eliminate counterparty credit risk in futures markets. Futures contracts are marked-to-market daily and losses are settled through variation margin, while initial margin acts as collateral. This system ensures that neither party can default at maturity.

Speculation vs. Hedging

Futures can be used for speculation by taking long or short positions to profit from expected price movements. They can also be used for hedging to offset the price risk of an existing exposure. For example, an equity portfolio can be hedged by shorting stock index futures. If the market falls, portfolio losses are offset by gains on futures, and if the market rises, portfolio gains...

The Restoration and the Origins of the English Novel

Restoration and Intellectual Origins of Enlightenment

The Restoration begins in 1660 with the return of the monarchy under Charles II after the Commonwealth. It marks a reaction against Puritan austerity and censorship. England experiences political stabilization and cultural renewal.

Science and Empiricism

There was a strong development of scientific thinking based on reason and observation. The influence of empiricism suggested that knowledge comes from experience. Francis Bacon promoted the scientific method, leading to the foundation of the Royal Society, which encouraged experimentation and rational inquiry.

Philosophy and John Locke

Emphasis was placed on rationalism, skepticism, and critical... Continue reading "Restoration Literature and the Rise of the English Novel" »

Why protection is needed
In multitasking or multi‑user systems, two programs might try to use the same memory at the same time, which can corrupt data or crash the system.
Protection mechanisms isolate user programs from each other and from the OS, and also help detect bugs by checking whether each memory access and instruction obeys certain safety rules.
Overview of 80386 protection
80386 has four protection levels (0–3), where 0 is most trusted (OS kernel) and 3 is least trusted (user apps).
It uses two main mechanisms: segment‑level protection and page‑level protection, and every memory access is checked against these rules before the actual memory cycle startsSegment‑level protection (idea)
Segment‑level protection has five parts:

Introduction to Financial Derivatives

Definition of a Derivative

Financial instruments allow contracting parties to buy or sell an underlying asset at a future date at a price agreed upon at the time of contracting. The underlying asset may be an equity asset, bonds, currencies, interest rates, commodities, and more. The effective purchase is only made on the maturity date and settlement, in some cases by physical delivery and in others by cash settlement for differences between the price originally agreed and that prevailing on the date of settlement or maturity of the transaction.

With these types of derivative instruments, it is possible to act in a leveraged manner since their purchase or sale does not require the availability of funds or... Continue reading "Financial Derivatives: Mechanics of Futures, Swaps, and Options" »

Lithium-Ion Battery: Construction, Working, and EV Application

Construction: A Lithium-ion battery consists of the following components:

• Anode (Negative Electrode): Made of graphite or carbon-based material that can intercalate lithium ions.
• Cathode (Positive Electrode): Composed of lithium metal oxide such as LiCoO2, LiMn2O4, or LiFePO4.
• Electrolyte: Lithium salt (such as LiPF6) dissolved in organic solvents that allows ion movement.
• Separator: Porous polymer membrane that prevents physical contact between electrodes while allowing ion flow.
• Current Collectors: Copper foil for anode, aluminum foil for cathode.
• Case and Terminals: Protective housing with positive and negative terminals.

Working Principle

During Discharge: Lithium ions (Li+) move from... Continue reading "Electric Vehicle Battery and Charging Systems: A Comprehensive Analysis" »

Polygon Rendering Methods Defined

• Polygon rendering methods are techniques used to calculate how 3D polygon surfaces appear when displayed on a 2D screen.
• They decide the distribution of light, color, and intensity on polygonal faces for realistic visualization.
• These methods control how smooth, bright, or sharp the surfaces look after illumination.
• They help convert geometric data into shaded, visible surfaces through lighting equations.
• These methods balance image quality and computational speed in computer graphics applications.

Types of Polygon Rendering Methods

Constant Intensity Shading (Flat Shading)

• Lighting is calculated once for the entire polygon, giving one uniform color.
• Produces a faceted appearance, where individual polygons are clearly
