Facebook changes its corporate branding to Meta - Techcrunch

Image credit - Facebook Well, it’s official. After 17 years of being called Facebook, the social networking parent company behind Facebook, Instagram, WhatsApp and Oculus has a new name. Facebook’s corporate entity is now Meta. Facebook creator Mark Zuckerberg announced the change at the company’s AR/VR-focused Connect event, sharing that the new title captured more of the company’s core ambition: to build the metaverse. “To reflect who we are and what we hope to build, I am proud to announce that starting today, our company is now Meta. Our mission remains the same — it’s still about bringing people together. Our apps and our brands — they’re not changing either,” Zuckerberg said. “From now on, we’re going to be metaverse-first, not Facebook-first.” The name change comes at a… convenient time for Facebook, which has seen a sustained backlash to its brand, particularly in recent weeks after a former employee leaked a trove of documents to the media and government bodies detailing the m

Apple AirTag Reviews:

Image © Unsplash One of the smallest and most affordable devices from Apple, the AirTag is also interesting for a number of reasons. This tiny, disc-shaped tracking device is made to work within the Apple ecosystem, giving you an easy way to keep tabs on small objects such as keys, wallets, backpacks, handbags, and cameras. There are similar products, including the Tile range of trackers and Samsung's Galaxy SmartTag, but the AirTag is smaller, looks better, and is designed to work well if you're invested in Apple's products and services.  Priced at   Rs. 3,190   for one   Apple AirTag , or Rs. 10,900 for a pack of four, this product serves a very specific purpose – helping you keep track of your belongings. Is it good at what it does? Find out in this review. What is Apple AirTag? The Apple AirTag is a tracking device that can be attached to a small personal object such as a bunch of keys, or placed inside a backpack, handbag, or suitcase. The device uses Bluetooth for con

The mystery of Elon Musk’s missing gas - Techcrunch

Image © Techcrunch The draft programmatic environmental assessment (PEA) for SpaceX’s Starship and Super Heavy launch vehicles, which Elon Musk hopes will soon be shooting into orbit and then on to Mars, was issued last month by the   FAA for public comment . The 142-page document covers construction and daily operations at SpaceX’s Boca Chica facility in Texas, which Musk is hoping to incorporate as a city called Starbase. These include pre-flight operations, rocket tests, launches and landings, as well as fuel, water and electricity supplies. A new pre-treatment system will purify and cool natural gas into liquid methane fuel for the Starship and Super Heavy rockets. Much more gas will be needed for a new 250-megawatt gas-fired power station. A power plant this big typically serves over 100,000 homes and can cost hundreds of millions of dollars. But while rocket launches get a lot of coverage in the PEA, the new power plant receives only a cursory mention. In particular, it is unclea

Do compasses work in space? - Big Think +

Image credit - Pixabay How do you find your direction in space that doesn't involve a magnetic field, out between the galaxies where really there's no detectable magnetic field at all? Everything is moving. There's nothing to say this point is still and this is the reference point we're gonna use and everything moves according to that point. We're moving around the sun at about 66,000 miles an hour right now. The sun is moving around the galaxy, around the core of the galaxy, at about half a million miles an hour. We are actually falling gravitationally into the center of a cluster of galaxies at about a million and a half miles an hour. And that's just when we say relative to what? Relative to the sun. Relative to this group of galaxies. There is no absolute standard of reference in the universe. Let's talk first about compasses, and then maybe talk a bit more about the idea of how we locate ourselves in space in general. A compass is something that respond

NASA’s Ingenuity Helicopter Captures a Mars Rock Feature in 3D

This 3D view of a rock mound called “Faillefeu” was created from data collected by NASA's Ingenuity Mars Helicopter during its 13th flight at Mars on Sept. 4, 2021. Image © NASA/JPL-Caltech NASA’s Ingenuity Mars Helicopter provided a 3D view of a rock-covered mound during its 13th flight on Sept. 4. The plan for this reconnaissance mission into the “South Seítah” region of Mars’ Jezero Crater was to capture images of this geologic target – nicknamed “Faillefeu” (after a medieval abbey in the French Alps) by the agency’s Perseverance rover team – and to obtain the color pictures from a lower altitude than ever before: 26 feet (8 meters). About 33 feet (10 meters) wide, the mound is visible just north of the center of the image, with some large rocks casting shadows. Stretching across the top of the image is a portion of “Artuby,” a ridgeline more than half a mile (900 meters) wide. At the bottom of the image, and running vertically up into the middle, are a few of the many sand ripp

Facebook lied about the risk to teens. Now, its plan to open the app to kids looks worse than ever

Image credit - Unsplash Facebook is in the hot seat again. The Wall Street Journal published a powerful multi-part series on the company this week, drawing from internal documents on everything from the company’s secretive practice of whitelisting celebrities to its knowledge that Instagram is taking a serious toll on the mental health of teen girls. The flurry of investigative pieces makes it clear that what Facebook says in public doesn’t always reflect the company’s knowledge on known issues behind the scenes. The revelations still managed to shock even though Facebook has been playing dumb about the various social ills it has sown for years. (Remember when Mark Zuckerberg dismissed the notion that Facebook influenced the 2016 election as “crazy?”) Facebook’s longstanding PR playbook is to hide its dangers, denying knowledge of its darker impacts on society publicly, even as research spells them out internally. That’s all well and good until someone gets ahold of the internal resear

Walmart to launch autonomous delivery service with Ford and Argo AI - Techcrunch

Image © Techcrunch Walmart has tapped Argo AI and Ford to launch an autonomous vehicle delivery service in Austin, Miami and Washington D.C., the companies said Wednesday. The service will allow customers to place online orders for groceries and other items using Walmart’s ordering platform. Argo’s cloud-based infrastructure will be integrated with Walmart’s online platform, routing the orders and scheduling package deliveries to customers homes. Initially, the commercial service will be limited to specific geogrpahic areas in each city and expand over time. The companies will begin testing later this year. Walmart and Ford have partnered before in a limited test with Postmates in fall 2018. In that pilot program, which focused on Miami-Dade County, they used simulated self-driving vehicles to study the user experience of delivering groceries. Argo was not involved in that study. This latest collaboration will use Ford vehicles integrated with Argo AI’s self-driving technology. The aim

Using Ultraviolet Light to Suppress Electrostatic Noise in Gravitational Wave Observatories - NASA

Image © NASA Gravitational waves are minute ripples in space-time caused by the most energetic events in the universe—like the collision of two supermassive black holes. To detect gravitational waves, we will measure the tiny variations in the motion of purely free-falling test masses housed in three Sun-orbiting spacecraft. The CMD is vital for ensuring that electrostatic charge buildup on the test masses does not disturb their motion and obscure the gravitational wave signal. Gravitational waves enable an entirely new way of observing our universe and therefore provide enormous potential for scientific discovery. The Laser Interferometer Space Antenna (LISA), a European Space Agency mission with a significant contribution from NASA, will be the first mission to detect and observe low-frequ

Crypto Metrics That Every Investor Must Know

Image credit - Pixabay Metrics are numbers that investors use to decide whether to buy, sell or hold a cryptocurrency. There are 6,317 cryptos being actively traded across 405 exchanges! This makes it hard to quickly decide whether a cryptocurrency is worth investing in, and so, If you are a serious investor, you must know about these 5 types of metrics: R = ROI and risk Let's talk about Return on investment (ROI), and risk metrics. Return on Investment (ROI) measures the amount of return on a crypto investment, relative to its cost. Cryptocurrency prices are notorious for large upward and downward swings. The 2 important crypto risk metrics are volatility and Sharpe ratios. Volatility Volatility measures the price fluctuations of a crypto. If a crypto has higher volatility, its value can be spread out over a larger range. The value of volatile cryptos can massively change in a short period. Conversely, a crypto with lower volatility is likely to be stable and subject to smaller sw
