Airbus Vertical Speed Indicators (VSI) primarily use a blended "baro-inertial" system to display precise vertical speed, combining responsive inertial data from the Inertial Reference System (IRS) with long-term stable barometric pressure data. The inertial signal is used for dynamic maneuvers and air data for stability over time. This hybrid... show more

When the Boeing 787 operates on autopilot, its sophisticated flight control system manages the flaperons to maintain stable flight, particularly during turbulence. The system continuously receives data from various sensors, including airspeed indicators, inertial navigation systems, and accelerometers. When turbulence is detected, the autopilot system automatically adjusts the position of the flaperons to counteract any rolling motions caused by gusts or disturbances in the airflow.

OpenAI's Deep Research is getting a run for its money. Deep Lake was just released, and it's a different take on an AI system that can do deep research on your own data. You can use Deep Lake to build AI search with reasoning on your private and public data. (Look at the attached videos to get an idea of how it works.) If you want to research proprietary and sensitive data, Deep Research won't help you because it's limited to public data. Deep Lake, however, will allow you to use your private data. On top of that, Deep Lake supports multi-modal retrieval from the ground up. It uses vision language models for data ingestion and retrieval so that you can connect any data (PDFs, images, videos, structured data, etc.) You can even use mixed-data queries! Deep Lake can search your data from S3, Dropbox, and GCP. It learns from your queries over time, making the results as relevant to your work as possible!

This Footage claimed to be from earlier tonight which shows the use of the “Iron Beam” Laser-Air Defense System in the Shoot Down of Rockets over Central Israel actually appears to just be either a Lens Flare from the Camera or a Reflection in the Clouds; also the “Iron Beam” is not meant to Intercept these kind of Projectiles and will primarily be used for Very Short-Range Interceptions from Mortar and Artillery Shells as well as some Drones.

🚨 CHINA IS PUTTING DATA CENTERS ON THE OCEAN FLOOR AND LETTING THE SEA COOL THEM. Instead of building massive air-conditioned buildings on land, China is submerging sealed server modules on the seabed. The ocean itself acts as a giant natural cooling system. This dramatically cuts energy use, water consumption, and land requirements for power-hungry AI data centers. Why this matters: • Seawater provides free passive cooling no giant chillers or evaporative systems needed • Combined with offshore wind power, many of these facilities run on mostly renewable energy • Projects like the one off Shanghai (Hailanyun/HiCloud) are already operational with hundreds of server racks • Early results show 30–90% lower cooling energy demand compared to traditional data centers The deeper implication is huge: As AI drives explosive growth in computing power, traditional data centers are becoming unsustainable due to electricity and water demands. Underwater data centers offer a clever way to scale AI infrastructure while reducing environmental strain on land. This could become a major trend turning the ocean into the new frontier for the data centers powering tomorrow’s AI. What do you think smart innovation or risky for marine ecosystems? Follow for more frontier technology and future infrastructure.

Bernoulli's Principle It’s a key idea in fluid dynamics named after Daniel Bernoulli. In simple terms: For a fluid flowing smoothly, an increase in the fluid’s speed happens at the same time as a decrease in pressure or a decrease in the fluid’s potential energy. Where: - P = pressure in the fluid - ρ = fluid density - v = flow velocity - g = acceleration due to gravity - h = height above a reference point Bernoulli's Principle basically says that for a fluid that's flowing smoothly, when its speed goes up, its pressure goes down. Think of it like this: fast-moving air or water pushes less sideways than slow-moving air or water. The energy in the fluid stays the same overall, but it shifts between motion, pressure, and height. That's why an airplane wing creates lift. The air moves faster over the curved top of the wing than underneath, so the pressure on top is lower. The higher pressure below pushes the wing up.

Our efforts are working. 69 cities, counties, and towns have imposed bans or moratoriums on new Al data centers driven by community resistance to surging energy and water use, higher utility bills, and lost land for farming and housing. Don’t let up. The fight is far from over. The people, not corrupt politicians in the pockets of billionaires and corporations, deserve to make decision for our communities. For this to happen long-term we must fundamentally change our system from capitalist to socialist.

Unique footage has emerged showing remote control of interceptor drones. The 190th Training Center of the SBS reportedly used a drone-interceptor to shoot down a Shahed UAV remotely, with the pilot located at a significant distance from the launch site. The system used was LITAVR, developed by FDrones. According to the company, an operator can control the interceptor from hundreds of kilometers away from the launch point. The F7 LITAVR is already a well-known and highly effective system. As a reminder, here are the technical details (this is all open-source information): Development of the system began in autumn 2024. It was successfully tested and officially adopted in summer 2025. Serial production and deliveries to the military started in autumn 2025. Maximum speed: 350 km/h Flight time: up to 15 minutes Equipped with two cameras: daytime and thermal imaging The officially stated tactical range is 36 km, though in practice it can reach up to 60 km and operate at altitudes of up to 9.5 km. The warhead (separately codified) weighs 500 g. Detonation can occur via kinetic impact, self-destruction upon contact with the target, or manual activation by the operator. The system uses inertial guidance without GPS and features automatic terminal guidance (“last mile” / target lock system). At present, it reportedly destroys hundreds of targets per week, including Shaheds, Gerberas, Molniyas, Orlans, Lancets, and others. What is fundamentally new? Until now, mobile air defense fire groups and frontline crews using interceptor drones required a qualified pilot on-site. It has now been successfully demonstrated that a different tactic is possible: pilots can operate from protected, remote locations. The only requirement is internet access at both the control center and the launch site. Ukraine’s defense sector continues to develop innovative solutions. 📹 Oleksii Kopytko/Facebook

Another night, another long arc east… London Heathrow Airport to Hong Kong 🇭🇰, the Airbus A350 settling into cruise while the world slides quietly beneath us. Lately there’s been plenty of noise about GPS jamming and spoofing, so here’s the calm, practical version from the flight deck. Jamming is simply interference, other electronic noise overwhelming the GPS signal so a receiver can’t hear it properly. Spoofing is more mischievous, that’s nefarious actors broadcasting a false signal that tries to convince the receiver it’s somewhere it isn’t. Both can be inconvenient. Neither is new. And neither is a show-stopper for modern aviation. Airliners were navigating oceans long before satellites were part of the picture, using inertial reference systems, radio navigation aids, dead reckoning, time, distance, and a healthy respect for cross-checks. Today’s aircraft layer all of that together. If one element like the GPS becomes unreliable, the system doesn’t panic, it recognises it swiftly, dumps it, and reverts to one of the other systems. Crews verify, cross-reference, and carry on. That’s the quiet strength of modern aviation and aircraft, redundancy and judgement. No single sensor gets a veto. No single failure defines the outcome. The airplane doesn’t need GPS to fly safely; it uses it when it’s trustworthy and ignores it when it isn’t. From the cabin, the night looks serene. From the flight deck, it’s deliberate, systems monitored, assumptions questioned, margins protected. Just as it’s always been. If you’d like to learn more about GPS jamming and spoofing, and the tragic event that released this military system for civilian aviation, you can preorder my book JUMBO on Amazon or at any good bookstore. Hong Kong by morning. Same principles. New technology. Calm continuity. #A350 #PilotLife #AviationSafety #AvGeek #FlightDeckView #LongHaul #Navigation #GPS #ModernAviation #AirlineLife #AboveTheClouds #SystemsThinking #GlobalAviation #JUMBO #JUMBObook

🇮🇱Elbit Systems is developing an airborne high-power laser interception system as the next generation of air defense following the Iron Beam. The system is planned to be installed on fighter aircraft or helicopters and will be able to intercept incoming missiles and drones outside Israel’s airspace. Compared with ground-based laser systems, it offers greater mobility and the ability to engage targets both above and below cloud cover. The core technology combines multiple fiber lasers into a single high-power laser source, while enabling stable airborne targeting and precise engagement. Its accuracy has been described as “hitting a coin from 10 kilometers away.” Israel aims to eventually establish a squadron of laser-equipped aircraft that could rapidly take off during large-scale attacks and use low-cost laser interceptions to neutralize large numbers of incoming threats. The capability is expected to gradually become operational within the next few years. source:

HiveMind is a superintelligent network in which a central AI (MIND) orchestrates a swarm of uniquely coded Minds that drive mass data ingestion and limitless content creation. For decades, our approach has been to create content first, then analyze it into data afterwards to understand what worked. This was always backwards - analyzing the aftermath rather than engineering the success from the start. Traditional Flow: Content → Data Analysis → Insights Content isn't one-size-fits-all - a cooking show that captivates a senior audience on YouTube might bore a teenager who craves quick, dynamic experiences. The challenge isn't just creating content; it's creating the right content for the right audience. We need to change this. This is where HiveMind's specialized agents transform the landscape. Each agent, while connected to the central MIND, excels in its unique domain. One agent masters the art of children's educational content, while another crafts compelling cooking narratives. Another might specialize in rapid-fire social content that resonates with Gen Z. Through HiveMind, every piece of content generated becomes new data that teaches the system to create even better content. The system gets smarter with every cycle, understanding at an increasingly sophisticated level what makes content effective and engaging. But the true power lies in the feedback loop. Every interaction, every engagement, flows back to MIND, enabling each agent to evolve and refine its approach. This isn't just content creation - it's content evolution. As audiences engage, agents learn, adapt, and improve, making each new piece more effective than the last. In essence, we're not just building content creators; we're developing specialized digital artists who understand their audience intimately and grow smarter with every creation. You can think of it this way: Data → Pattern Recognition → Optimized Content → Engagement Data → Even Better Content Tzar

What is the RAT? The RAT is a small wind turbine stowed within the aircraft fuselage and deployed automatically when certain failure conditions are met. Once extended into the airstream, it uses the forward motion of the aircraft to spin and generate power—mechanical, hydraulic, or electrical. Primary Functions of the RAT on the 787-8 1. Hydraulic Backup Power On deployment, the RAT drives a variable displacement inline hydraulic pump. It pressurizes the center hydraulic system, enabling continued operation of critical flight control surfaces such as the ailerons, elevators, and rudder. This is vital in maintaining aircraft controllability if normal hydraulic sources are lost. 2. Supplementary Electrical Power While the RAT is primarily a hydraulic power source on the 787-8, it can also, in some configurations, drive an emergency generator. This generator provides sufficient AC and DC power to support essential avionics, flight displays, and communications systems. Deployment Scenarios: When Does the RAT Automatically Deploy? The RAT on the Boeing 787-8 deploys automatically—without crew input—under the following emergency conditions: 1. Dual Engine Failure If both engines fail, resulting in the loss of engine-driven electrical and hydraulic generation, the RAT deploys to maintain critical flight control power. 2. Complete Electrical Loss to Flight Instruments If there’s a total loss of electrical power to both the captain’s and first officer’s primary flight instruments, the RAT ensures these systems remain powered. 3. Low Pressure in All Three Hydraulic Systems If all three systems—Left, Center, and Right—lose hydraulic pressure, the RAT provides emergency hydraulic power through the center system. 4. EMP Failure + Engine Loss During Takeoff or Landing If all four Electric Motor Pumps (EMPs) fail and an engine fails during takeoff or landing, the RAT deploys to sustain flight control power during these critical phases. Automatic and Autonomous Operation One of the RAT’s key advantages is its fully autonomous activation. Pilots do not need to manually deploy it; the system is designed to react immediately to predefined failure logic, reducing workload and ensuring flight-critical systems remain powered. In Summary The Ram Air Turbine (RAT) on the Boeing 787-8 is not just a backup—it's a lifesaving last resort. It deploys automatically to supply hydraulic and limited electrical power when all other power sources fail. Designed with layered redundancy in mind, it is one of the unsung heroes of modern aircraft systems, ensuring that even in worst-case scenarios, pilots retain control to guide the aircraft—and its passengers—safely to the ground.

Our aero kit for the 2024+ Model 3 Performance is designed using CFD to enhance performance while preserving Tesla’s renowned efficiency. Shown here is the exploded view of the aero kit parts to show how we accomplish our goal: to work with the Model 3 Performance foundation without disturbing it. The kit now delivers 1896N of downforce, shifting the car from net lift to substantial downforce with a minimal drag increase of just 1.93%. This is achieved through advanced aerodynamic techniques, such as splitter tunnels that enhance front ground effect—features rarely seen on street-legal vehicles. The kit enhances downforce in areas that already have high-pressure air, such as above the grille, over the side inlets, and on top of the front splitter, but also introduces entirely new shapes like the front undertray. Airflow management around the wheels and side skirts is critical for reducing drag and offsetting the added drag from downforce-generating surfaces. Additionally, placing a wing that is highly optimized to minimally disturb Tesla’s refined wake is crucial for maintaining efficiency. While we’re working out a few more final touches with our production run, we are just as excited to reach out to those who have patiently waited and look forward to providing order updates soon!

Additionally, placing a wing that is highly optimized to minimally disturb Tesla’s refined wake is crucial for maintaining efficiency. While we’re working out a few more final touches with our production run, we are just as excited to reach out to those who have patiently waited and look forward to providing order updates soon!

* SEGA GENESIS/MEGADRIVE - SCALING PART 1 * I've been exploring software scaling on the 68k cpu using a background layer rather than scaling sprites. There are a few advantages, no sprite boundaries to worry about so moving pixels is faster also cheaper vertical scaling by adjusting vertical scroll midscreen. The net result is you can manage larger scales more efficiently as the CPU can spend more time working on the horizontal scaling whilst the VDP helps with the vertical scaling (there is still a non trivial cpu cost there though). Here I'm scaling an early image of the Lufthoheit logo - but the goal is to use this in the game also for very large scales / either background effects or bosses. The scaler and Interupt handler are written in Assembly for speed and I think could be faster yet with some optimisations, word alignment moves etc. The scaler has the ability to expand > full screen in height (from a more limited base height) and up to 3x the image width at present. I need to add double buffering and possibly go a bit larger yet. I'm excited to get these effects into the game as large scaling effects we didn't often see on the Genesis !

Back massage is not only a relaxing practice, but also an effective support method for the musculoskeletal system and neurohormonal balance. In daily life, the back area is one of the areas where the most tension accumulates due to posture, stress, and muscle strain. The controlled pressure applied during the massage provides relaxation in muscle fibers, increases regional blood circulation, and supports oxygenation to the tissues. This process also reduces muscle spasms, contributing to the alleviation of pain. Physiologically, the effects of massage are not only local. Systemic effects such as a decrease in stress hormones like cortisol, an increase in endorphin and serotonin levels, and an increase in parasympathetic activity in the autonomic nervous system provide both physical and mental relaxation. The most frequently observed benefits are: Reduced muscle stiffness, relief from back and neck pain, improved circulation, improved sleep quality, general relaxation, and reduced stress. Incorrect technique or excessive pressure can lead to: trauma to muscle tissue, increased existing pain, and soft tissue damage. Situations requiring attention: Acute muscle injuries, serious spinal pathologies, infections, or febrile conditions. In such cases, an assessment should be made before applying massage. In summary, the effectiveness of massage comes not from the intensity of the pressure, but from the correctness of the application. Therefore, it is very important to have massages performed in places where the correct application is carried out.

We continue to analyze the technical details of the war with Iran, and we would like to note the Iranian novelty - subsonic barraging anti-aircraft missiles Missile 358, equipped with compact turbojet engines. To some extent unexpectedly, they showed good effectiveness against Israeli reconnaissance and strike UAVs Hermes-900. The key role is played by the thermal homing head: it is able to reliably detect and track a wide range of heat-contrasting targets, including UAVs with various flight profiles. An additional advantage is the command and telemetry channel, which ensures data transmission and allows for radio correction of the trajectory. This is especially important in situations when the target attempts to disrupt the capture with infrared decoys or other means of counteraction. According to the stated parameters, the range of application of Missile 358 reaches about 100 km. At the same time, the maximum interception altitude is about 8.5 km, and the speed is up to 700 km/h, which expands the capabilities of the complex in covering objects and intercepting medium-altitude UAVs. Of course, this is a niche tool, and compared to solid-fuel missiles, the turbojet engine provides exponentially higher flight energy. This allows to dramatically increase the range at low speed, and the mass of the main units of the ammunition, its warhead and control system. On the other hand, this is a solution of necessity, because classic anti-aircraft missiles perfectly hit such high-altitude and slow-moving targets. But for such ammunition, no radar, complex and expensive beam installations are required, which greatly improves its survivability under constant air strikes. And in its niche of targets, there are enough of them, as such UAVs of Israel and the USA are the basis of UCAV, and are constantly over the territory of Iran. So with the 358th ammunition, you can score quite a lot of frags, and significantly complicate air strikes on Iran for the Epstein coalition. Russian Engineer -
