Fun with magnets by Bhagya
This document discusses different types of magnets such as bar magnets, ring magnets, and cylindrical magnets. It explains that magnets have north and south poles and that unlike poles attract while like poles repel. Some uses of magnets include in credit cards, TV/computer screens, and data storage devices. Magnets can lose their magnetism if exposed to impacts, heat, or other stresses.
Fun with magnet
This document summarizes different types of magnets and how they were discovered. There are four main types of magnets: horseshoe, bar, cylindrical, and ball-ended. Magnets produce invisible magnetic fields that attract ferromagnetic materials like iron. Permanent magnets are objects made of magnetized materials that create their own persistent magnetic fields, like refrigerator magnets. Ferromagnetic materials like iron, nickel, and cobalt are strongly attracted to magnets.
CH-FUN WITH MAGNET
According to Greek legend, magnetism was first discovered by a shepherd named Megnes in Megnesia, Greece. His iron stick and nails had become attracted to a magnetic rock, which was named magnetite after the shepherd or country. Magnets have two poles, a north pole and a south pole, which always exist in pairs and cannot be separated. A compass uses a magnetic needle that aligns in the north-south direction, with its red end pointing north.
Magnets
Iron particles are lined up when a magnet is brought close to iron. When two bar magnets are placed close together with the same poles facing, they will repel each other. The magnetic field consists of field lines that emerge from the North pole and reenter at the South pole. Magnets are made of iron, nickel, or cobalt. Magnetic materials such as iron and steel are attracted to magnets, while non-magnetic materials like plastic and wood are not. To preserve a bar magnet, it should be stored with another magnet to maintain its magnetic field.

A Greek shepherd named Magnes discovered magnets in ancient times when he found that nails in his shoes and the tip of his stick were attracted to stones in the ground while digging. Magnets attract certain materials like iron, nickel, and cobalt that are called magnetic materials. All magnets have two poles - a north pole and a south pole - and can attract or repel other magnets depending on which poles are interacting. Magnets are now used for many purposes like refrigerator door closures and magnetic pins or stickers.

1 induced magnetism
An induced magnet only becomes magnetic when placed within a magnetic field, such as near a permanent magnet. The induced magnetism is temporary and lost when removed from the magnetic field. The most effective way to induce magnetism is by passing a direct current through a solenoid coil containing the material. Materials can also be demagnetized by heating, hammering, or exposing to an alternating current within a solenoid coil. Soft iron is easily magnetized but loses magnetism quickly, while steel is harder to magnetize but retains magnetism longer.
magnets
A shepherd named Magnus discovered an unusual black rock that mysteriously pulled his iron staff and sandal nails towards it. This led to the discovery of other rocks with similar magnetic properties, which were named "magnets" after either Magnesia or Magnus. Magnets come in various shapes and sizes and are known to interact with certain metals.
Unit 3 magnets
This document describes different types of magnet shapes including U-shaped, ring, horseshoe, circular, bar, and cylindrical magnets. It notes that while some shapes look similar, they are different. The document also discusses magnetic poles, explaining that magnets have two poles and will attract when poles are opposite, but repel when poles are the same.
Magnetism Science Physics e Learning
This document discusses magnetism and magnetic fields. It describes testing magnets by bringing specimens near magnet poles to observe attraction or repulsion. Induced magnetism occurs when an unmagnetized material becomes a magnet when near a permanent magnet. The document also discusses the theory of magnet domains, methods of magnetization and demagnetization, and plotting magnetic field lines. It provides examples of magnetic field patterns for single and multiple magnets, including the neutral point between magnets with like poles facing. Finally, it compares the magnetic properties of iron and steel.
Magnetism
Bar magnets are permanent magnets that always have two poles: a north pole and a south pole. Unlike poles attract each other, while like poles repel. Magnets create invisible magnetic fields that are strongest at the poles and can be detected using iron filings. To test if a metal object is a magnet, you check if it repels another known magnet, since both magnetic and non-magnetic metals are attracted to magnets.
Magnetic poles
Magnets have two poles called the north and south poles located at either end. The rule of magnets is that like poles repel each other, while unlike poles attract each other. This means that two north poles or two south poles will push away from each other, while a north pole and a south pole will be drawn together.
MAGNETISM
This document discusses different types of magnets including natural and artificial magnets. Natural magnets are obtained directly from nature while artificial magnets are prepared by humans using elements like iron, cobalt, or nickel. It also describes the general properties of magnets including that they have two poles (north and south poles) and opposite poles attract while like poles repel. Applications of magnetism are discussed such as maglev trains which use magnetic levitation to move fast without wheels touching rails. The document also explains how the Earth itself acts as a giant magnet and was discovered to have magnetic poles by William Gilbert, known as the "Father of Magnetism".
SIMPLE PHENOMENA OF MAGNETISM
This document discusses the basic properties and phenomena of magnetism. It describes how magnets have two poles (north and south) and magnetic field lines that run from the north to south pole. Magnetic materials like iron and steel can be magnetized when placed near a magnet, while non-magnetic materials like copper, aluminum, and plastic are not affected. Electromagnets produce temporary magnetic fields when electric current flows through a coil wrapped around an iron core, whereas permanent magnets retain their magnetism. The document also covers the Earth's magnetic field and how to identify magnetic field patterns using iron filings or a compass.

Summary fun with magnets
Magnets can be natural or artificial. Natural magnets are made of magnetite, an iron ore with magnetic properties. Artificial magnets are made from iron, nickel, or cobalt. Magnets have different shapes like bar, horseshoe, cylindrical, or ball. They attract iron, nickel, and cobalt. Magnets have north and south poles and can attract or repel each other depending on whether the poles are opposite or the same.
Magnetism science physics e learning
- Testing a magnet involves bringing each end of a specimen near the north pole of a bar magnet. Attraction indicates a magnetic material, while repulsion indicates a permanent magnet.
- Induced magnetism occurs when an unmagnetized magnetic material like iron becomes magnetized upon contact with a permanent magnet. However, induced magnets only maintain magnetism temporarily.
- The magnetic field is the region around a magnet where other magnetic objects experience a force. Magnetic field lines are used to represent the pattern and direction of this field.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
