The document discusses the process of capital accumulation through the production of iPhones. It shows that while the total cost of parts for an iPhone is approximately $188, the phone retails for $800 in Australia, generating a profit of $605 for Apple. This profit is generated primarily from the labor of workers, who are paid far less than the value they create, demonstrating the inequality between the working class and capitalist class under modern global capitalism.Word press security

This document discusses securing a WordPress website. It begins by explaining the typical LAMP stack environment used to run WordPress and each component's known vulnerabilities. It emphasizes the importance of knowing your hosting environment, only using secure connection methods like SFTP, using strong unique passwords, and staying up-to-date on software. The document then outlines common attack vectors like injections, backdoors and defacements. It provides tips for hardening WordPress through configuration changes and plugin use to limit access and vulnerabilities.Team Urbanism - Driving to Happiness

The document discusses how driving may not actually promote happiness and proposes alternatives that could improve happiness. It analyzes how driving relates to factors of gross national happiness like health, community vitality, and living standards. Obesity and subsidies are increasing while community engagement and costs are decreasing in car-dependent areas. The document presents examples from other cities where car-free solutions like walking school buses and public transit have increased health, community, and affordability over driving.

The document describes two mini-projects analyzing Twitter data:
1. It analyzes the prominence of followers for celebrities Britney Spears, Mariah Carey, and Ashley Tisdale by calculating a prominence ratio and finding statistics. It finds Mariah Carey has the most prominent followers based on the median ratio.
2. It extracts tweets from Seattle, WA and Southampton, UK containing phrases like "I want pizza" and "I want to sleep" to compare preferences. It also analyzes tweets with "Monday" vs "Friday" to study mood. It finds pizza is more popular in Seattle tweets while sleep is slightly more popular in Southampton tweets. Both cities seem more negative on Mondays than thankfulSoc prashanth harish

The document analyzes data from Twitter to compare preferences and sentiments between two geographic locations. It:
1) Extracted tweets containing the phrase "I want" from Seattle, WA and Southampton, UK and analyzed the prevalence of terms like "pizza" and "sleep" to compare food and activity preferences. It found pizza more commonly mentioned in Seattle tweets.
2) Also extracted tweets mentioning "Monday" or "Friday" paired with terms like "I hate" and "Thank God" to analyze sentiment towards weekdays. It found more negative Monday mentions compared to thankful Friday mentions, especially in Seattle.
3) Used statistical tests to analyze the results and plot the findings, finding preferences and sentiments differed somewhatProblem

Women in Pakistan face many issues such as being treated like slaves, not being able to vote or go to school, and not being able to own property even after divorce. The document proposes letting women make their own decisions, allowing them to vote, and changing laws to give women the same rights as men to solve these problems.Problem

Gradient image blendingPrashanth Kannan

The document discusses a technique for gradient image blending that seamlessly blends a foreground image into a background image using Poisson image editing. It formulates the blending as a system of linear equations where the gradient of the blended image must match the gradient of the foreground image inside the blended region, while matching the background image on the boundary. The system is solved using Jacobi's method through an iterative process to minimize the error between the calculated and actual gradient values.

This document contains prominence ratio data for celebrities Britney Spears, Mariah Carey, and Ashley Tisdale, including their mean, median, and standard deviation values. Britney Spears had the highest mean prominence ratio of 0.493 and largest standard deviation of 3.403, while Mariah Carey had the highest median prominence ratio of 0.154.Dual photography

This document describes the concept of dual photography, which uses Helmholtz reciprocity to interchange lights and cameras in a scene. It discusses how the transposed transport matrix can be used to generate virtual captured images from virtual projected patterns. It also describes different methods used to capture the transport matrix, including fixed pattern scanning and adaptive multiplexed illumination. Limitations discussed include scenes with significant global illumination effects and situations where the camera and projector are at a large angle.Recovering high dynamic range radiance maps from photographs

This document summarizes a technique for recovering high dynamic range radiance maps from multiple low dynamic range photographs with varying exposures. It involves constructing an aggregate mapping from sensor irradiance to pixel values using a least squares approach to solve for the unknown camera response function and irradiance values. This allows combining exposures to reduce noise and obtain radiance maps that can be used for image-based rendering with an extended dynamic range compared to a single photograph.SAP Education - Essential for the Success of each Digital Transformation

The document discusses the importance of education for successful digital transformation. It states that skills are essential for taking advantage of digital possibilities, and lack of knowledge is a major barrier. The SAP Education portfolio provides training, consulting services, and software solutions to help employees develop relevant digital skills and ensure organizations can effectively manage learning. Examples are given of how the portfolio supports the needs of business users and IT professionals during digital transformation.More Related Content
