Offensive cyber security: Smashing the stack with Python
: A necessary step in writing secure code is having an understanding of how vulnerable code can be exploited. This step is critical because unless you see the software from the vantage point of a hacker, what may look to be safe and harmless code, can have multiple vulnerabilities that result in systems running that software getting p0wned. The goal of this tech talk is to provide a step-by-step illustration of how not adhering to secure software design principles such as properly bounds checking buffers can open up computing devices to exploitation. Specifically, we will show that by using a very easy to use scripting language like python, we can do the following: 1) Smash the stack of a system running vulnerable code to gain arbitrary access. 2) Install a key logger that can phone home to a command and control server.

The Raspberry Pi is a series of credit card–sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.
The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online. Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers.
The original Raspberry Pi is based on the Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and was originally shipped with 256 megabytes of RAM, later upgraded (models B and B+) to 512 MB. The system has Secure Digital (SD) (models A and B) or MicroSD (models A+ and B+) sockets for boot media and persistent storage.

05 module managing your network enviornment
Upon reading the document, the key steps in a router's start-up process can be summarized as follows:
1. When power is applied, the router performs a power-on self-test and loads the bootstrap code from ROM to initialize hardware and find the IOS image.
2. The IOS image is then loaded from flash memory or another source such as TFTP into RAM where it is decompressed and executed.
3. The startup configuration is loaded, typically from NVRAM. If no configuration is present, the router enters setup mode to configure initial settings.
Sockets
Sockets provide an abstraction for network communication between processes. They define endpoints for connections that are identified by IP addresses and port numbers. There are two main types - stream sockets which provide reliable connected service using TCP, and datagram sockets which provide unreliable datagram service using UDP. To use sockets, an application creates a socket, binds it to an address, listens/accepts for incoming connections, and sends/receives data. Key functions include socket(), bind(), listen(), accept(), connect(), send(), and recv(). Select() allows monitoring multiple sockets to avoid blocking. Proper use requires consideration of addressing, port numbers, error handling, and blocking behavior.
I2C Drivers
The document discusses Inter-Integrated Circuit (I2C) drivers in Linux. It covers I2C protocol basics like start/stop conditions and transactions. It then describes the I2C subsystem in Linux including I2C adapter, client and core drivers.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
