1) Sails and flags placed in urban areas and convection currents can transfer heat energy upstream or slow the loss of energy to the atmosphere. 2) By creating friction, sails and flags can convert kinetic air energy to heat energy, intensifying convection currents and increasing the overall heat in the area. 3) Strategically placed sails in an urban environment could harness convection currents to power transportation and ventilation, and potentially cause combustion if enough energy is accumulated in the center of the rising convection mass.

Energy transfer 15.2
The document discusses energy transfer in the atmosphere. It notes that the sun provides most of Earth's energy, with about 35% reflected back into space and 65% absorbed. Of the absorbed energy, 15% is absorbed by the atmosphere and 50% by Earth's surface. Heat is transferred through the atmosphere via radiation, conduction, and convection. Radiation transfers energy from the sun, conduction transfers energy through contact between warm and cool objects, and convection transfers heat through circulating air currents. The water cycle is also summarized, where water evaporates from surfaces and transpiration, condenses to form clouds, and falls as precipitation.
Energy transfer in the atmosphere and oceans
The document discusses various ways that energy is transferred within the atmosphere and between the atmosphere and oceans/land. It describes how the sun's radiation is absorbed, reflected, scattered, or transmitted by gases in the atmosphere. Thermal energy is also transferred via conduction, convection, and radiation. Convection currents globally distribute heat. Prevailing winds are influenced by these currents. Ocean currents similarly redistribute warm and cold water around the world through processes like the global conveyor belt. Latent heat absorption and release also influences global climate patterns.
Atmosphere, Energy, & Wind
The document describes characteristics of Earth's atmosphere including its composition of nitrogen, oxygen, argon, and other gases. It discusses air pressure and how it is created by the weight of the atmosphere above. The atmosphere provides services like moderating temperatures, protecting from radiation, and powering weather systems. It describes how energy is transferred through the atmosphere using radiation, conduction, and convection. Specific layers of the atmosphere and processes like the greenhouse effect and water cycle are also outlined.
Energy transfer in atmosphere & hydrosphere
The document discusses energy transfer in the atmosphere and hydrosphere. It explains that the atmosphere and hydrosphere absorb and store thermal energy from the sun, acting as heat sinks to help regulate Earth's temperature. Radiation from the sun is mostly absorbed by gases in the atmosphere like water vapor, carbon dioxide, and ozone. Conduction and convection transfer heat within the atmosphere. The hydrosphere includes water in oceans, lakes, ice, and vapor in the air. The water cycle involves evaporation, condensation, and precipitation. Ocean currents influence global and regional climates.
Earth science 8.2
This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
My power point
The document summarizes how energy from the sun is transferred within the Earth's atmosphere and surfaces. It explains that some solar energy is reflected by gases and particles in the atmosphere, while some is absorbed by the land and water, warming the Earth's surface. It also describes the different methods by which heat is transferred, including radiation from the sun or fires, conduction between touching substances, and convection through fluid movements like air currents.
Marine Wave Notes
Waves transport energy through a medium and can be characterized by their amplitude, wavelength, frequency, period, and speed. There are two main types of waves - transverse waves where the medium moves perpendicular to the direction of energy transport, and longitudinal waves where the medium and energy move parallel. Ocean waves are created by wind pushing on water, with larger fetches and faster winds producing larger waves. Wave properties change in deep and shallow water, and different types of ocean waves include seas, swells, and surf breaks near shorelines. Tsunamis are large waves caused by earthquakes or other seismic events.
Syncline
Convection currents transfer heat through the mass movement of heated particles into cooler areas of fluid. They occur in oceans, rivers, seas and under the Earth's surface, moving magma and being used in some military weapons. Convection currents flow from areas of higher temperature and pressure to lower temperature and pressure.

Enegy transfer v5
There are two main ways that energy from the sun is transferred around Earth - through the atmosphere and oceans. In the atmosphere, convection currents caused by uneven heating from the sun create wind patterns and transport thermal energy from the equator to higher latitudes. In the oceans, warm and cold water currents similarly transport thermal energy around the globe as denser cold water sinks and warmer water rises. Ocean currents such as the Gulf Stream carry energy from the equator to northern latitudes.
Solar energy and it's affect on Earth's atmosphere
This PowerPoint explores how the sun's radiant energy affects the different layers of atmosphere. Specifically, it focuses on the effect solar energy has on Earths surface to create wind through the uneven heating of Earth's different surfaces (land vs. water)
Earth Systems Science Notes
This document discusses key concepts in systems science. It defines a system as interconnected parts forming a whole and describes open systems that exchange matter and energy with surroundings and closed systems that do not. Feedback occurs when a system's output becomes its input and can be negative, stabilizing around an average, or positive, driving large changes. Earth system science considers interactions between the atmosphere, hydrosphere, geosphere, and biosphere as well as human impacts. The hydrosphere includes all water, the biosphere all living things, the lithosphere the solid Earth, and the atmosphere the air surrounding Earth.
Winds
The document describes characteristics of Earth's atmosphere and different types of winds. It defines winds as air movement caused by differences in air pressure from high to low pressure areas. Heat rises because hot air is less dense than cold air, as heat makes air molecules move faster and take up more space. The document lists different types of prevailing winds like trade winds, westerlies, and polar easterlies. It also defines local winds and jet streams.

The document discusses harvesting energy from urban heat islands through wind turbines placed in cities. It explains that the uneven heating of urban surfaces creates convection currents and warm rising air masses, which can be captured by wind turbines. However, other urban cooling strategies like green roofs may reduce the potential for heat island energy harvesting. Overall, the document considers how wind and air flows in cities could be better understood and engineered to more effectively extract energy from the urban heat island effect.
Meteorological discussions
Convection occurs when lighter, warmer air rises and is replaced by heavier, cooler air sinking. To effectively harvest urban heat, wind turbines must be precisely placed where replacement air is entering to take the place of rising warm air. The rising air itself is not causing the wind, but the movement of cooler air into the space left behind. Any distance from this location means the effect dissipates. Harvesting heat in this way may slow the air flow cycle and create unique energy patterns. It could reduce the volume and density of air after energy removal, requiring more air to displace warm air and slowing convection. Heating during the day may return air flow to normal patterns or cause higher pressure over cities. Some heated air energy may conduct
Things we can do to keep power in the lines
There are several ways to store excess power generated during periods of low consumption, including:
1) Recycling processes and street lights could operate during these times.
2) Manufacturing may also be able to shift to off-peak periods.
3) Lifting weights via tracks that lower to generate power could store energy.
Storing power in this way creates a "loop" where energy remains within the system through various forms like electricity, heat, and wind.

concept of reentry heating
1. There are three main modes of heat transfer: radiation, conduction, and convection. Radiation transfers heat through electromagnetic waves, conduction through physical contact between particles, and convection through fluid flow.
2. During atmospheric reentry, a shock wave forms in front of the vehicle as it compresses the air. This shock wave heats the air molecules, which then transfer heat to the vehicle primarily through convection. Higher reentry velocities result in higher heating rates.
3. Vehicles with more blunt, rounded shapes experience lower maximum heating rates compared to streamlined shapes due to differences in how the shock wave interacts with the vehicle surface. Blunt shapes spread heat transfer over a larger area while stream
Convection concepts for the ancients and beyond
This document discusses airflow patterns in ancient architecture and their implications. It suggests that religious structures like temples, pyramids and cathedrals may have been designed not just for religious purposes but also to improve airflow and public health by gradually warming and cooling the air, preventing rapid temperature fluctuations and disease outbreaks. It notes how ancient populations would have been highly sensitive to microclimates created by buildings and how subtle architectural features could have significantly impacted living conditions and population capacity over time through trial and error.
Understandings of a second sun, volcanoes
The document discusses using volcanoes and structures like flags to create a second sun through convection currents. A network of sails and flags around a volcano would create friction in the convection current, transferring heat energy from the volcano through the air mass. This would allow the area to store thermal energy longer than through natural convection alone. Flags and other objects in the convection current would further increase heat and slow the dispersion of energy by converting some air kinetic energy back to heat through friction. The goal is to generate enough heat and pressure to cause combustion and a self-sustaining "second sun" that would provide benefits like cleaning the air, increasing wind power, and attracting people to the area.
The pyramids
The document proposes that the pyramids may have been built to create convection currents and airflow through densely populated ancient cities. By being taller structures that heated up differently than the surrounding areas, pyramids could draw in cooler air from outside and circulate it through the cities. This would help disperse pollutants and make the urban environments more comfortable to live in.
Atmosphere & surface energy balance
The document discusses concepts related to solar radiation and Earth's energy balance. It begins by describing how the Sun generates energy through nuclear fusion and emits it as electromagnetic waves. It then defines insolation as the amount of solar radiation reaching a given area, noting it varies by location and time. Finally, it explains that Earth's climate is powered by solar energy and achieves radiative equilibrium when the amount of incoming solar energy balances the amount radiated back to space, keeping global temperatures stable.
Physics
Physics is the science that describes the fundamental forces and interactions in nature. It explains everyday phenomena like light, sound, motion and heat through concepts like energy, matter and forces. Physics underpins many modern technologies from electronics and computers to transportation and medical devices. It has applications in areas like mechanics, optics, thermodynamics, electricity and magnetism. Physics seeks to understand the universe from the smallest subatomic particles to the large-scale structure and history of the cosmos.
Wind Power Presentation
The document discusses the generation of wind and factors that influence wind patterns such as uneven heating of the earth's surface and differences in land and water. It then covers Bernoulli's principle and how lift force is generated on airfoils in wind, allowing wind turbines to harness this force. The key types of wind turbines - horizontal axis and vertical axis - are compared in terms of their design, efficiency, and power output. The Betz limit for maximum theoretical power extraction from wind is derived based on kinetic energy equations. Challenges of new high altitude wind power concepts are also mentioned.
Speech one.
Sail-enhanced wind turbines and widespread adoption of sailing for freight transport could establish a global sailing network. This would allow for increased harvesting of wind energy and could lead to a scenario where increased energy consumption results in more available energy overall. As infrastructure and techniques develop over time, it may become possible to capture and store nearly all energy on Earth, enabling unprecedented access to energy.
wind energy.pptx
This document discusses where wind energy comes from and how wind turbines harness that energy. It explains that wind is caused by uneven heating of the atmosphere from the sun, and the rotation of the Earth influences global wind patterns. Wind turbines convert the kinetic energy of wind into electrical energy using rotor blades, a drive train, and generator housed in a nacelle. Siting considerations for wind turbines include average wind speed, wind distribution and structure, altitude, terrain features, and proximity to infrastructure.
The radiant energy receiver system of nikola tesla
Nikola Tesla proposed a system to capture energy from the Earth's natural electric field using a "Radiant Energy Receiver". In the late 1890s, Tesla hinted at discovering a way to directly power devices by connecting them to the "ambient medium" or natural electric and magnetic fields surrounding Earth. Tesla believed this vast, inexhaustible source of energy could be tapped to help mankind. In a 1900 article, Tesla described his idea to use a thermopile extending between the Earth and outer space to convert the natural heat gradient into electricity. However, he realized a more practical method was needed without reaching such heights. Tesla proposed creating an "artificial cold sink" that could continually draw heat energy from the
18660767 basics-of-wind-energy-conversion
This document discusses principles of wind energy conversion. It begins by explaining that wind turbines transform the kinetic energy of moving air into mechanical energy. It then summarizes Albert Betz's early 20th century work developing the theoretical limits of energy that can be extracted from wind, known as Betz's law. The document goes on to provide mathematical expressions for kinetic energy of air and volume flow rate. It also discusses common wind turbine designs, construction details like blades and towers, and operational concepts such as tip speed ratio and variable pitch. Finally, it covers factors that influence wind patterns like differential heating, mountain winds, katabatic winds, and geostrophic winds.

Global warming occurs when the incoming solar energy exceeds that being radiated back into Space from the upper atmosphere in the form of infra-red radiation. Well over half the outward transmission of energy from the Earth’s surface through the troposphere occurs in the form of convection. There is often a significant barrier to convection within a “boundary” layer in the lowest two kilometres of the troposphere. This impediment can be reduced by several methods. One of these is arguably the vortex engine.
vortex_version_2016
This document proposes utilizing updraft systems to sustainably generate electrical power by taking advantage of the latent heat released when atmospheric water vapor condenses. It discusses how water vapor in the atmosphere contains a significant amount of energy, comparable to 1,200 cubic km of fuel oil. This energy can be partially harvested through systems like vortex engines to not only lift water and initiate precipitation but also generate non-polluting electrical power. Enhancing tropospheric convection through these means could help mitigate global warming by more effectively transporting heat from the lower to upper atmosphere.
Ocean,Tidal and Wind Energy
The document provides an overview of various types of ocean energy resources including wave, tidal, ocean thermal, and salinity gradient energy. It notes that the theoretical global resource for wave energy is 8,000-80,000 TWh/yr, 800 TWh/yr for tidal current energy, and up to 10,000 TWh/yr for ocean thermal energy. This is a significant amount of energy that could meet or exceed current global electricity consumption of 17,000 TWh/yr. The document also describes some of the technologies used to capture these resources such as oscillating water columns for wave energy and tidal barrages for tidal energy.
A smart way to extract tidal energy
This document describes a simple method to extract tidal energy using a long barrel placed in the ocean. As tides rise and fall, they force air in and out of the barrel, spinning a turbine connected to a generator. Only a barrel, turbine, generator and placement site are needed. It can provide low-cost electricity to power street lights in coastal villages. The system captures free kinetic energy from tides rather than wasting it, meeting basic energy needs in a sustainable way.

Crowded interiors would be a defining feature of private ships. Supply bags and containers would fill the interior spaces, leaving barely any room to move around. Characters would have to squeeze between bags and would only be able to see each other between them. For poor contractors and salvagers, leaving anything behind would be unthinkable, so they would pack their ships to the point where movement could be dangerous during high-G maneuvers. Experienced spacers, however, would feel uneasy without being surrounded by bags. Being placed in the open spaces of holding cells could even trigger panic attacks for spacers accustomed to tight, packed quarters.

This document describes a proposed space drone racing game. It discusses allowing players to:
1) Place gates on different space-themed arenas and save/share custom maps.
2) Select from different drone configurations and tune their power, weight, and fuel.
3) Have an "edit mode" where gates can be placed and reordered by connecting to them freely without physics.
4) Save, export, import maps and play in free flight or timed race modes against other players.
FAQ.docx
- The document is a set of FAQs regarding the creator's controller project. The creator prefers prototyping over making shells due to comfort and customization reasons. They do not want to start a business as that is not their objective, and getting all manufacturers on board would better achieve their goals of new games. The fundamental inspiration was a lack of existing games in a specific environment they want to experience. While others have made similar games, none are a complete match. The creator looks forward to but does not try to make their own game due to lack of skill and project size. They share their project to hopefully increase demand for the types of games they want rather than start an uncontrollable kickstarter. Their ultimate goal is
There's no Space Drone Racing Simulator
The document proposes the idea of a space drone racing simulator. Some key points:
- It envisions drone races taking place inside the ISS, with small drones navigating hoops. Races would focus on efficiency and navigating courses before exhausting fuel.
- The drones would be modeled after NASA's SPHERES, powered by compressed gas like CO2 with 20-30 seconds of thrust.
- An ideal simulator would allow customizing courses, drone properties, control schemes, and physics models to explore different racing scenarios in space.
- Rather than developing it alone, the author hopes their idea inspires others to create such a simulator, as they think it could be very engaging if done well.
space FPV racing
Pilots on the ground could compete in space FPV drone racing by flying small, slow drones launched from a suborbital vehicle or space station. The drones would use cold-gas monopropellant for propulsion, limiting them to traveling only a few meters at very low speeds within a small inflatable course. A suborbital vehicle could achieve enough zero-gravity time for multiple 2-minute racing heats before the drones and vehicle fall back to Earth and are destroyed upon impact. This approach allows competitive racing with minimal latency for drone controls from the ground and avoids the high costs and challenges of operating drones in orbit.
first arguments for complex controllers and manual robotics
discussing why despite improvements in automation, users should control robots, and exactly how is the best way to go about it:?::
Variations on the expanse (1)
This document outlines an idea for an alternative sci-fi setting inspired by the TV show "The Expanse." In the setting, a fungus-like organism called the protomolecule is developed by humans on Earth instead of being of alien origin. When tested on the asteroid Eros, fragments spread to Venus after Eros is destroyed, allowing the protomolecule to terraform Venus into a habitable planet. The document discusses how hybrids and colonization of Venus might occur in this alternative scenario.
The Legend of Super Mario Bros. (Revisited)
The document reimagines the story of Mario Bros. in a future where a massive moon-based infrastructure called the "Superstructure" has been built. Mario and Luigi work as plumbers in the Superstructure's vast drainage system. They become embroiled in a rebellion against the upper classes and go on the run. They encounter strange new animals, including Yoshi, and work to stop Bowser's plan to destroy the Superstructure's energy system, which would endanger all its inhabitants. In the end, both Mario and Bowser sacrifice themselves to stop a flood and save the Superstructure, while Yoshi also gives his life to help them save the city.
mariobros (updated)
The Mario Brothers find themselves lost in the enormous drainage system of a future megastructure called the Superstructure. There they encounter evolved animals like Yoshi the dinosaur. Yoshi helps the brothers and shows them that the Superstructure is in danger of collapsing, which would kill most of the world's population. Bowser plans to cause an energy overload that would destroy the Superstructure. Using their skills as plumbers, Mario and Luigi work with Yoshi to stop Bowser's plan by stabilizing the infrastructure. However, Yoshi sacrifices himself so the brothers can save the Superstructure, and Mario, Luigi and Bowser all perish in the resulting flood that stabilizes the structure.
Mariobros
The Legend of the Super Mario Brothers is set in a future where a massive superstructure that houses more people than ever before has been constructed. Mario and Luigi work as plumbers in the superstructure's enormous infrastructure. They must race to save the superstructure after the militant Bowser plans to overload the energy system through a construction project, which could destroy the structure and kill its inhabitants. Mario, Luigi, and their dinosaur friend Yoshi work to stop Bowser's plan, though it ultimately leads to Yoshi sacrificing himself so the brothers can flood the area and safely disperse the overloading energy, even if it means they and Bowser perish in the process.
Ufo's and no_sonic_boom
The document discusses the possibility that particle collisions in the Large Hadron Collider could produce tiny localized gravity effects. It suggests that within the area of such a collision, some particles could experience a force similar to gravity due to energy turbulence. However, this would not result in a net gravitational pull outside of the collision area. As an analogy, it compares this to how a paddle creates small whirlpools that pull on nearby water but do not change the overall water level. It further speculates that such localized gravity fields could enable new forms of propulsion for spacecraft by reducing g-forces during acceleration and allowing easier interstellar travel.
How to lift rocks in the ancient world
a walkthrough of a mechanical concept of the ancient world, that appears to be difficult to find a description of online.
Pilum into shield
The document questions whether a Roman scutum shield would rotate when hit by a pilum spear based on a video. It notes that in the video, the shield was fixed in place, allowing the pilum to easily penetrate without resistance. However, if the shield was able to rotate as a soldier would hold it, the movement could create friction to slow or stop the pilum from fully penetrating, as the sides of the hole in the shield would pinch the pilum. It concludes by asking if such rotation could result in bending the pilum.
Pogo rocket
The document describes a proposed "Rocket-Pogo" device that would allow astronauts to maneuver in space. The Rocket-Pogo would have simple controls, including thrust, stabilize, and brake. Thrust would come from a downward facing thruster, allowing the astronaut to orient the device as needed. Stabilize would lock the attitude of the Rocket-Pogo to arrest any rotation. The basic usage would involve using stabilize to position the body, then position and stabilize the Rocket-Pogo before thrusting. Some key advantages discussed are that a handheld device like this would help maintain a stable posture during acceleration and allow acceleration in any direction by pointing with the hands.
Resistance bomber scene newtonian
The document discusses the strategy and physics of using bombs in space combat according to Newtonian physics. It explains that bombers normally deploy bombs from a safe distance to intercept enemy ships in orbit, but the Resistance bomber had to approach the enemy Dreadnought directly and deploy all of its bombs at once to destroy it, which was an extremely risky maneuver. Deploying bombs can also force enemy ships to maneuver and prevent them from launching fighters for a period of time.
Fake swords everywhere
The document discusses the design and manufacturing process of gladius swords. It provides several key points:
1) Gladius swords were designed to be very strong and durable weapons that would serve their purpose if needed by the hero wielding them.
2) Modern historians are biased in their analyses based on what artifacts have survived, rather than considering that most swords produced were likely ordinary quality given the high costs of expert craftsmanship.
3) Swords have a round cross-section because hammering out the metal from an ingot naturally curves it as the material thins, in addition to a round shape producing a sharper blade.
Space game concepts 1
This document outlines ideas for gameplay mechanics in a space-based game focused on close-quarters navigation and drone-style racing. Key points include:
- Orbital mechanics would not be a core focus; gameplay would involve navigating nearby objects with short distances traveled.
- Rotation would be stabilized by thrusters or reaction wheels, each with pros/cons like jittery control or need for cooldown.
- The game would include many non-racing navigation courses for skill improvement, along with options for player-created courses and multiplayer racing.
- Drone racing courses could also be imported to take advantage of their design expertise and community sharing features.
- Delivery or taxi games set in dense fut
Death star approach newtonian
The X-wing must execute a near-impossible maneuver to destroy the Death Star. It must approach at maximum speed, perform a perfect full-power turn around the Death Star, and come to a complete stop at the exhaust port while firing. The torpedo must fly directly down the port without hitting the walls. Only by stopping inside the trench surrounding the port can the pilot avoid being vulnerable to the Death Star's defenses during this maneuver.

This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Mythology or energy science
- 1. Mythology or energy science? From the chamber of secrets
- 2. A sail transfers energy upstream in the wind. By creating friction the sail causes energy to transfer into the sail as heat, and then back into the wind, still as heat (effectively transferring the energy upstream). Also the sail focuses wind energy, making it possible to focus energy up or cross stream directly as kinetic energy.
- 3. A flag in the convection current is a source of friction.The friction of the flag will cause an energy transfer and conversion. Some kinetic energy of the flowing air will become heat once again. The heat will cause the air to expand, and the normal convection will occur. The heat of the overall convection system is still more intense than a flags heat, so the system retains its general flow. This WILL alter the convection current overall, but will also have the effect of increasing the heat, and slowing the dispersion of energy from the area. The energy is, in effect, “pulled back”. The heat then contributes to the normal heat, resulting in more powerful convection, and more intense friction.
- 4. An urban area loses heat through convection As the air warms, it becomes lighter and rises off the city. In a city with a central high point, the air makes an airflow pattern as depicted.
- 5. If placed strategically in the urban area, sails would slow the loss of energy from the urban environment.
- 6. The area normally loses significant amounts of energy to the atmosphere. By creating a delay, the area would contain much more energy than without the sails.
- 7. As this energy increases in magnitude, there would become a clear center of energy.
- 8. With enough energy, Combustion!
- 9. As the energy “mass” increases in size, it’s center will be higher in the sky. So, as the sailors skillfully increase the available urban energy, the center bright spot will rise.
- 10. This could be where this song came from: A STAR, RISING IN THE EAST!
- 11. Why raise the star? • Wind could drive ventilation and transportation. • A well built urban area could have a circular sail road powered by this shape of convection if the wind were powerful enough. • This would be like a city-wide highway with 24 hour powered transit. • Ventilation would allow for increased population density in more ways than one. Rooms can hold more breathers at once, and urban areas can remain clear of pollutants like human sh*t! (and disease!)
- 12. Why don’t WE make one? Dub Railroad movie poster 1 (draft) urban heat index power company
