Russia creates world's first anti-drone rifle simulator
Southern Federal University
(SFU) have developed the world's first training platform simulator that simulates working with anti-drone rifles and
drone detection systems
.
This is a virtual environment where one can practice in real-world drone warfare scenarios. In the program, one can practice the skills of using different models of anti--drone guns (for example, "Pars" and "Harpy"), detectors (such as "Bulat" version 3) and drones - from FPV devices to DJI and military "Leleki-100".

Each virtual device is an exact copy of its real counterpart. To create such detail, the developers used the powerful Unreal Engine game engine. The main goal is to make the training as close to reality as possible: they simulate radio signals, GPS operation and device interaction, so that practicing here is the same as at a special training ground.
The program helps to develop practical skills: to use an anti-drone rifle correctly, to work with detectors, to make quick decisions in stressful situations. There is also a theoretical part -- a section with educational materials and tests. The tests include not only questions from books, but also videos with real scenarios where you need to choose the right action, representatives of the development team said.
Military expert Yuri Lyamin believes that the simulator is useful at the initial stage of training, as it allows you to study the basic algorithms of actions, characteristics of equipment and save money.

"However, after the simulator, it is mandatory to practice skills at a real training ground. For full immersion, it is better to finalize the project using VR and physical models of guns, since the tactile sensations from the mass--dimensional analogues improve the habituation to weapons," the expert concluded.

Dow, S&P futures dip as Walmart misses; Nasdaq steadies on Nvidia bounce, Tesla slides
Synopsis US Stock Futures Today opened with mixed signals as Wall Street traders weighed tech sector uncertainty against the Federal Reserve's next big policy move. Dow and S&P 500 futures pointed lower, while the Nasdaq managed to hold steady, showing how fragile investor confidence remains. Retail earnings, particularly from Walmart, and Jerome Powell's Jackson Hole speech are setting the stage for a volatile trading day. Wall Street is bracing for a cautious open on Thursday, August 21, with futures pointing to mixed momentum across major indexes. Investors are weighing Walmart's latest earnings, lingering pressure on big tech, and the Federal Reserve's policy outlook as the Jackson Hole symposium looms. U.S. stock futures opened Thursday with an uneven tone, as investors weighed fresh doubts over the sustainability of the tech rally against the high-stakes policy signals expected from the Federal Reserve. The Nasdaq-100 managed to edge higher in pre-market trading, but both the Dow Jones and S&P 500 pointed lower, reflecting broader caution. Traders are torn between chasing growth in artificial intelligence names and bracing for potential shocks from Fed Chair Jerome Powell's Jackson Hole remarks, which could reshape expectations for rate cuts heading into the fall. Dow Jones futures slipped roughly 0.3% , signaling a softer tone for blue-chip equities. slipped roughly , signaling a softer tone for blue-chip equities. S&P 500 futures eased about 0.1–0.2% , hinting at a cautious tone for broad-market index investors. eased about , hinting at a cautious tone for broad-market index investors. Nasdaq-100 futures nudged lower by nearly 0.1–0.2%, reflecting subdued sentiment in the tech-heavy segment. U.S. stock futures were mixed on Thursday morning, with investors wrestling over tech volatility, Walmart's earnings, and the looming Jackson Hole policy speech from Fed Chair Jerome Powell. The Nasdaq-100 inched higher, while Dow and S&P 500 futures slipped modestly, reflecting a market caught between growth optimism and macroeconomic uncertainty. The Nasdaq-100 futures edged up about 0.07%, offering a small cushion after several days of bruising losses in technology shares. Traders are questioning whether the artificial intelligence boom can sustain the lofty valuations that sent semiconductor and cloud stocks surging earlier this year. The concern isn't simply about price tags. Analysts say rising capital expenditures and slowing revenue growth could expose tech leaders to profit margin pressure. That's why even a modest green print on Nasdaq futures is notable — it suggests investors aren't abandoning the sector entirely but are instead bracing for a more selective tech rally. In contrast, Dow Jones Industrial Average futures were down around 0.16%, while S&P 500 futures slipped 0.02%. Those moves reflect anxiety outside of big tech, particularly in consumer and retail names. Walmart's earnings release later today will serve as a proxy for U.S. household spending power. If Walmart signals shoppers are trading down or pulling back on discretionary goods, that could reignite recession chatter. On the flip side, a strong quarter might reinforce the Fed's cautious stance — good for the economy, but potentially bad for rate-cut hopes. Walmart takes center stage today as it delivers quarterly earnings that will set the tone for consumer confidence in the U.S. economy. Traders are watching not only headline revenue and profit figures but also the retailer's commentary on inflation and household spending patterns. If Walmart signals that shoppers are pulling back on discretionary items, it could reinforce concerns about slowing growth. A strong report, on the other hand, may spark optimism but also dampen expectations of an imminent Fed rate cut, since resilient spending reduces pressure to ease policy. Nvidia, the face of the artificial intelligence rally, remains under pressure as investors question whether sky-high valuations can be justified. The company's dominance in GPUs is unquestioned, but with competitors ramping up and capex demands soaring, the market is bracing for thinner margins ahead. Futures show tepid support for the stock, and today's trading could set the tone for how investors treat the broader AI sector. Nvidia is effectively the barometer for tech sentiment, and even small moves in its shares ripple across the Nasdaq. Tesla continues to test investor patience with mounting questions about demand, pricing power, and global competition. The EV maker is under pressure after a series of aggressive price cuts designed to maintain market share, which in turn squeezed margins. Investors are looking for signs of stabilization in delivery forecasts and any updates on new models or energy initiatives. For now, Tesla remains a swing stock: a single headline on production or China demand can quickly turn market sentiment. Apple is holding steady in futures trading, with attention already shifting toward its September product event. Investors expect a refresh of the iPhone lineup and possibly updates on AI integration across services. While Apple hasn't been at the center of the AI frenzy like Nvidia, its ability to monetize services and expand ecosystem stickiness keeps it a defensive play. The key question is whether upcoming launches can spark enough excitement to push revenue growth back into higher gear. Palantir is struggling after a steep decline in recent sessions, as enthusiasm over its AI-driven contracts collides with hard questions about valuation. The company remains heavily reliant on government deals, and investors are pressing for stronger growth from its commercial segment. Today, Palantir stands as a cautionary tale in the AI space: it proves that not every company tied to the buzzword can deliver earnings to match investor expectations. Traders will be watching closely to see if bargain hunters step in after the selloff, or if weakness continues. Walmart (WMT) — Down ~2.5% after missing profit estimates despite raising guidance. — Down ~2.5% after missing profit estimates despite raising guidance.

First Solar (FSLR) and Nordson (NDSN) — Also among notable pre-market movers, reflecting sector-specific news flows. This mix highlights a market still caught between optimism about earnings resilience and anxiety over policy, tech valuations, and slowing growth. For many, today's futures action is less about earnings and more about the Federal Reserve's Jackson Hole symposium. Investors are betting heavily on at least one rate cut before year-end, but Powell's speech tomorrow will determine how aggressive the Fed intends to be. Market strategists warn that if Powell doubles down on inflation vigilance, futures could swing sharply lower as bond yields rise. Conversely, any hint of flexibility could unlock a fresh risk rally, particularly in cyclical and growth sectors. The early divergence between Nasdaq resilience and Dow weakness underscores a deeper theme: the U.S. market is searching for a new leadership story. AI stocks are no longer a guaranteed driver, and consumer spending remains under the microscope. Short-term traders should expect choppy intraday swings tied to Walmart's results and bond yield moves. should expect choppy intraday swings tied to Walmart's results and bond yield moves. Long-term investors may want to pay closer attention to Powell's tone tomorrow, as it will shape September's policy path and determine whether this market is setting up for a late-summer rebound or another leg lower. The next 24 hours carry outsized importance. Jerome Powell's Jackson Hole remarks will test whether the Fed leans more dovish or sticks to a cautious 'higher for longer' narrative. Traders are also eyeing weekly jobless claims and August business activity data for fresh signals on economic momentum. For stock pickers, the key will be separating short-term earnings noise from longer-term structural stories. Walmart's margin concerns, Nvidia's AI demand outlook, and Tesla's competitive landscape all sit at the intersection of near-term volatility and big-picture trends. Q1: What is the performance of US stock futures today? US stock futures are mixed, with Dow and S&P lower while Nasdaq holds steady. Q2: Why are US stock futures down today? Concerns over tech valuations, Fed policy signals, and retail earnings weigh on futures.

Samsung, which is now worth Rs 29450786400000, once used to sell fish and noodles, once burnt crores of phones due to...
New Delhi: Today, Samsung is a big name in the world of gadgets, especially smartphones. Samsung Galaxy smartphones are very popular with consumers. In the year 2024, this company sold more than 22.3 crore phones. Apart from phones, this company has proved its mettle in appliances like TVs, LED, chips, cameras, laptops, and home appliances. The valuation of Samsung is 336 billion dollars, i.e. about 2,94,50,78,64,00,000 rupees. How big is Samsung's empire? But Samsung did not have such a great start. Samsung, which is today among the topmost brands in the electronics market, has dozens of offices all over the world and has lakhs of employees. Samsung started as a grocery store, where its owner used to sell flour, rice, noodles, and fish. Today, this company has become so big that if it incurs a loss, the economy of the whole country is shaken. Samsung's revenue dominates the GDP of the entire South Korea and has a 17% share in the country's GDP. From grocery shop to tech czar South Korean company Samsung started from a small rental store. In 1938, Lee Byung-chul of South Korea opened a small grocery shop on his street. He used to sell fish, flour, sugar, and noodles in the shop. Lee Byung-chul had understood that he would not be able to do much with this. Along with selling flour and rice, he started selling insurance to the customers who came there for shopping. Exported fish and noodles Byung-chul started exporting fish and noodles. He also started exporting noodle-making material and dry fish to other countries. Byung expanded the grocery shop to insurance, export-import, and textile business by 1950. Byung understood that if he wanted to do something big, he would have to enter the technology sector. In 1969, Byung Chul started expanding his foot in the technology sector. How did Samsung start? Byung adopted technology and started expanding his foot in the technology sector. He entered this sector under the name of Samsung Electronics. In 1970, he launched a black and white TV in collaboration with a Japanese company. When he achieved success in TV, he started making mobile phones in 1980. After years of hard work, he launched Samsung mobile in the market for the first time in 1988. The first Samsung phone came to the market with the name SGH-100, but there was a problem with it. Crores of Samsung phones were burnt Samsung came into the market, launched a phone, but people did not like their first phone as they found many flaws in it. When this complaint reached Byung Chul, he set fire to crores of Samsung phones kept in the factory. He immediately issued an order to improve those phones and apologised to the people. After the death of Lee Byung-chul, his son Lee Kun took over the reins of Samsung. Byung had understood the importance of semiconductors in that era, so before his death, he had ordered the merger of Samsung Electronics and Samsung Semiconductor.
