Air pressure ppt
Air is made up of tiny particles that move randomly at high speeds, exerting pressure on surfaces according to their kinetic energy. Air pressure decreases with higher altitude as there are fewer particles above pressing down. The pressure exerted by air particles is demonstrated through applications like syringes, siphons, and drinking straws which rely on differences in air pressure.
Air pressure and weather
Air pressure is a measure of the force of air pressing down on the Earth's surface. It can vary depending on factors like temperature, water vapor content, and elevation. Higher elevations have lower air pressure since the atmosphere exerts less force the further one is from sea level.
Air pressure wind
Air pressure decreases with increasing altitude and is affected by temperature, humidity, and elevation. It is measured using a barometer. Differences in air pressure cause winds to move from high to low pressure areas. Global wind patterns like trade winds and jet streams curve due to the Coriolis effect. Local winds are influenced by geographic features and temperature variations between land and bodies of water. Changes in weather occur when different air masses characterized by their temperature and moisture content meet at fronts like cold fronts and warm fronts, which can lead to thunderstorm formation.
Air pressure
Air pressure is the weight of the atmosphere pressing down on the earth. It is measured in units called millibars using a barometer, which often contains mercury in a glass column like a thermometer to measure changes in pressure.
Atmospheric n gas pressure
The document discusses atmospheric pressure and how it is caused by the weight of air above the Earth's surface. It explains that atmospheric pressure decreases with increasing altitude as there is less air above. Instruments like mercury barometers, aneroid barometers, and manometers can be used to measure atmospheric pressure. Gas pressure inside a container is also explained using kinetic molecular theory, where gas molecule collisions with the container walls exert pressure.

The document describes a science lab activity for kindergarteners called "Mister Water" where students will explore the properties of water by observing rain in a glass and discovering how water can change colors with the addition of tempera paint or paper. Students will also explore flavors by mixing and tasting water with items like lemon, grapefruit, syrups and cocoa to discover how flavors can be changed.

1. The document describes several experiments involving light and color, including using a spinning color wheel or prism to demonstrate that white light is composed of the visible color spectrum.
2. One experiment uses colored paper to show that black absorbs the most heat from a light source, while white reflects the most heat.
3. Another experiment uses a prism or water glass to separate white light into a rainbow spectrum, and then uses a magnifying glass to recombine the colors into white light.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

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:

A tale of scale & speed: How the US Navy is enabling software delivery from l...
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
