IPC would be a suitable institution to distribute the writer's rock music magazine because IPC already publishes a large number of magazines and has experience distributing magazines in the rock genre, such as NME. Choosing IPC could allow the magazine to benefit from IPC's existing distribution network while the magazine's focus on a younger audience would provide IPC an opportunity to reach a new demographic.
El documento describe dos principios del aprendizaje: el aprendizaje autónomo y el aprendizaje significativo. El aprendizaje autónomo se basa en que el estudiante es el protagonista de su propio aprendizaje, mientras que el profesor provee recursos. El aprendizaje significativo ocurre cuando los estudiantes relacionan nuevos conocimientos con sus conocimientos previos bajo su interés, facilitando la adquisición, retención y aprendizaje activo de la información. Ambos enfoques reconocen la importancia de los conoc
Bitcoin transactions can be malleated by altering how data like signatures are encoded, changing the transaction hash while still remaining valid. This property, called transaction malleability, was exploited in attacks against MtGox in 2014, allegedly enabling the theft of 850,000 BTC. However, research presented found that using malleability attacks, likely less than 386 BTC could have actually been stolen from MtGox prior to its bankruptcy. The presentation then detailed how transaction malleability arises in Bitcoin due to the flexible encoding of data in transactions and how signatures are not tied to the transaction content or structure.
[Usenix's WOOT'14] Attacking the Linux PRNG and Android - Weaknesses in Seedi...srkedmi
1) The document discusses weaknesses in the seeding of entropy pools and low boot-time entropy in the Linux PRNG used in Android.
2) It presents a proof-of-concept attack that allows recreating the internal state of the Linux PRNG during early boot by leveraging an active leak of a random value and knowledge of the boot flow and PRNG behavior.
3) The attack is demonstrated through two scenarios: an IPv6 denial of service attack and bypassing Android stack protection to enable buffer overflow exploits.
This document discusses social media marketing and the role of an SMM manager. An SMM manager is responsible for developing successful social media strategies through objectives and targets, market research, and using various promotion tools. Common errors made include relying on bots, focusing only on subscriber numbers, frequent style or content changes, expecting quick results, using tricks or experiments without an audience, thinking SMM is easy or cheap, focusing only on one's enthusiasm rather than the visitor experience, and relying only on paid advertising. Effective SMM requires strategic planning and understanding one's target market.
Greg gets pressured into trying cocaine by his friends just once, but becomes addicted. The film aims to show that drugs never end well and can lead to problems like debt or fights with dealers. It also wants to demonstrate that peer pressure should be avoided, as saying no is sometimes best to prevent unwanted outcomes like addiction.
This document discusses several topics related to Chinese culture and ethnic groups, including traditional Chinese medicine, Chinese minorities, expressions of love for China, Tibetan Buddhism, Chinese folk songs, and the Mongolian people. The document touches on a variety of cultural aspects in a short list without much additional context.
La investigación-acción es un proceso sistemático para mejorar las cuestiones que afectan la vida cotidiana a través de la participación, con el objetivo de facilitar el desarrollo profesional de los educadores. Se lleva a cabo en espiral de tres pasos - planeación, acción y resultados - para estudiar problemas en la práctica docente y encontrar formas nuevas de apoyar el aprendizaje de los alumnos. Privilegia el análisis cualitativo para describir situaciones y entender los efectos de intervenciones.

[Blackhat EU'14] Attacking the Linux PRNG on Android and Embedded Devicessrkedmi
This document discusses attacking the Linux pseudo-random number generator (PRNG) on Android and embedded devices. It begins by motivating the attack by describing a previous vulnerability discovered in the Android keystore. It then provides an overview of the Linux PRNG and describes how an attacker could reconstruct the PRNG's internal state by simulating PRNGs with different seeds and comparing to leaked values from the real PRNG. It discusses problems with mounting the attack and where leaks could be obtained, such as during the kernel or platform boot process. It then describes a local attack method using a malware to obtain a PRNG seed and bypass stack canary protection.
Laptops are portable computers that contain most of the same components as desktop computers, including a display, keyboard, pointing device, and speakers in a single compact unit. Common laptop features include an integrated display screen, keyboard, AC power source or rechargeable battery, and ports/slots. Laptop processors are designed to use less power and create less heat than desktop processors to allow for longer battery life. Displays are typically built-in LCD, LED, OLED or plasma screens ranging from 7 to 20 inches.
This document discusses child labor in Bangladesh. It states that around 5 million children aged 5-14 are economically active in Bangladesh, and 3.2 million are considered child laborers according to ILO definitions. Child labor is widely accepted socially and economically in Bangladesh. The document outlines some of the common forms of child labor such as working in tea stalls, roadside sales, welding shops, auto workshops, tobacco factories, and more. The health risks to children who engage in labor are also discussed, such as physical injuries, poisoning, growth deficiencies, and long term health problems. Bangladesh has enacted some laws aimed at protecting children and eliminating child labor, such as the Labor Act of 2006 and the National Child Labor Elimination Policy of 2010
The document discusses the need for multiliteracy in the 21st century classroom. It explores various sources that argue students must develop skills beyond traditional literacy to communicate and learn in a technology-driven world. Multiliteracy involves teaching students to interpret and create multimodal texts using visual, audio, and spatial modes of meaning in addition to print. Effective multiliteracy pedagogy employs strategies like scaffolding, multiple intelligences, project-based learning, and fostering students' home languages in diverse classrooms. As technologies continue advancing, multiliteracy skills will remain important for lifelong learning.
