Not content to keep things simple or easy, SpaceX plans to catch its upcoming Super Heavy booster rockets at the launch tower, allowing for subsequent relaunches a mere one hour later.

Not to be confused with the Falcon Heavy, the Super Heavy will serve as the booster stage for SpaceX’s upcoming Starship system. The second stage of the system will be Starship itself, which is designed to launch and land on its own. When paired with the booster, however, Starship will be transformed into a formidable launch system, capable of delivering cargo and dozens of passengers to Earth orbit, the Moon, and Mars.

The Super Heavy, like the Starship second stage, is still in development, and specifications are very much in flux. Originally, the Super Heavy booster was supposed to land with retractable legs similar to those seen on the company’s Falcon 9 reusable rocket. But as SpaceX CEO Elon Musk explained in a recent series of tweets, they’ve rejigged the concept.

“We’re going to try to catch the Super Heavy Booster with the launch tower arm, using the grid fins to take the load,” he tweeted in response to an inquiry. “Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount—ready to refly in under an hour,” added Musk.

That SpaceX is designing a system capable of launching Starships at one hour intervals points to the company’s future ambitions. It remains to be seen if these gigantic boosters—which will measure 230 feet tall (70 meters) and 30 feet wide (9 meters)—can indeed be caught in this way, but Musk’s impressive track record means we need to take this prospect seriously.

Equipped with over two dozen Raptor engines, the Super Heavy booster will exert over 16 million pounds of force. By comparison, Block 2 of NASA’s upcoming SLS system will provide 9.5 million pounds of thrust.

On December 12, SpaceX performed a high-altitude test of a Starship prototype rocket, which blew to pieces while attempting a landing. Musk described it as a “successful ascent,” adding that “we got all the data we needed.” New Starship prototypes are currently being readied for further testing, but no dates for these launches have been released.

Graphcore Series E Funding: $710m Total, $440m Cash-in-Hand

https://www.anandtech.com/show/16346/graphcore-series-e-funding-710m-total-440m-cashinhand

For those that aren’t following the AI industry, one of the key metrics to observe for a number of these AI semiconductor startups is the amount of funding they are able to generate. While funding is no explicit guarantee of success, it does indicate perhaps how much faith the venture capitalists (as well as OEMs and other silicon vendors) have in the technology. One of the most well-funded ventures in this space is Graphcore, and the company just announced its latest Series E funding round of $222 million, taking it to $710m total across the five rounds.

Graphcore, based in Bristol UK, is already on its second generation product, launching the Colossus MK2 GC200 in 2020. This chip contains 60 billion transistors, 900MB of built-in memory, is manufactured on TSMC’s N7 node at 823 mm2, and can achieve 250 TFLOPs of AI compute. Graphcore bundles four of them into a 1U chassis along with an Arm-based control chip and a crazy amount of networking to enable a network containing up to 64000 chips. Customers can order this IPU-M2000 unit, or 16 of them in a dedicated rack. Graphcore also provides the POPLAR software stack, with direct support for PyTorch, TensorFlow, ONNX, and PaddlePaddle machine learning frameworks.

The latest $222m Series E funding round was led by Ontario Teachers’ Pensions Plan Board (what?), with additional funds managed by Fidelity International and Schroders as new investors. Previous investors also participated, including Baillie Gifford and Draper Esprit. With the latest round of funding bringing the total up to $710m, this would put Graphcore at #2 in terms of AI Chip pure-play startups. This is just behind the $850m invested into Chinese semiconductor startup Horizon Robotics, founded by a CEO Yu Kai a Baidu veteran, of which the latest $150m round finished in December. SambaNova is #3 with $456m, and Nuvia has $293m. The latest round of funding brings Graphcore’s valuation to $2.77 billion.

With Graphcore’s first generation product, the company aligned with Dell to provide server units featuring eight add-in PCIe cards, each with two of its first generation IPUs. The company is claiming that the newest second generation MK2 is rolling out to more customers even during COVID times, especially to academic research such as UMass, Oxford, and ICL. Official details on its corporate customers seem somewhat thin, beyond an official tie-in with Microsoft, however Graphcore has said that they are currently working with hyperscalers and financial service companies.

This is perhaps why Graphcore also stating that it has $440m cash-in-hand is quite important. As every startup has an effective burn rate of capital, this should be sufficient for the company to also go out to enable more customers, as well as develop next generation products. Graphcore has already announced through TSMC that it is already scoping TSMC’s 3nm process for a future product line. Graphcore is also a member of the recently formed MLCommons, the governing body behind MLPerf, and expects to participate with its first submissions on MK2 in Q2 this year.

Zelda: Breath Of The Wild NPCs Are Reportedly Advanced Miis, Modder Discovers How To Insert New Ones

https://www.gamespot.com/articles/zelda-breath-of-the-wild-npcs-are-reportedly-advanced-miis-modder-discovers-how-to-insert-new-ones/1100-6485832/


The Legend of Zelda: Breath of the Wild appears to use a modified version of the Mii character creator for its NPCs, and clever modders have even found a way to insert their own Mii files into Hyrule.

Eurogamer reports that dataminer HEYimHeroic discovered the files, which are referred to as “UMii”s in the Breath of the Wild code. The UMiis use facial components from the classic Mii designs, albeit with a greater level of detail and some stylistic touches to make them match the Breath of the Wild art style. UMiis do lack some features from their Wii/3DS counterparts, like moles and certain hair designs.

The discovery quickly led to the realization that modders can inject their own custom Mii designs into Breath of the Wild. That goes for many human and Hylian characters, but not the more distinct and less humanoid races like Gorons.

Main characters are bespoke designs that can’t be replaced via UMii editing. Still, it’s a neat way to inject some fresh faces into the Nintendo Switch classic, if you want your customized NPC to have a brush with the legendary hero.

In India, Smartphones and Cheap Data Are Giving Women a Voice

https://www.wired.com/story/india-smartphones-cheap-data-giving-women-voice/


Ravi Agarwal, author of the 2018 book India Connected: How the Smartphone Is Transforming the World’s Largest Democracy says that for many Indians, the smartphone is their first private TV screen, personal music player, computer, and camera. Agarwal compares it to the experience of owning a car for the first time—autonomy, privacy, and mobility.

Its influence goes far beyond other phones—the infrastructure that made the iPhone also enabled drones, smart-home gadgets, wearables, and self-driving cars.

This is particularly true for women, who are less likely to be literate or employed in the formal workforce. Even among the literate, many read and write in one of India’s more than 30 official languages—another hurdle to accessing the internet on personal computers and laptops with English keyboards. In 2015, only 10 percent of internet users in India’s rural areas were women. As smartphones and data plans have become more accessible, that figure has risen to roughly 30 percent, according to IAMAI, a trade group of internet and telecom companies.

Companies including Google, Intel, and Facebook have worked with local organizations to make it easier for women to access the internet. Google and Tata Trusts, for example, run the Internet Saathi, or Internet Friend, program, which trains rural women to be digital pioneers. They are taught to use smartphones in sessions where they are provided with phones and power banks. By December 2019, the program had trained more than 83,300 women to be Saathis. In turn, they had introduced over 34 million women to the internet.

Raman Kalyanakrishnan, the head of strategy at Tata Trusts, says the Saathis can decide what and how they want to teach, though the four-day training period emphasizes using voice commands in local languages. “We don’t assume we know what interests women all over the country,” he says.

Pinky Katariya, 36, is a Saathi from Jind, northwest of New Delhi, who joined the program in May 2018. She married young and lived with her in-laws when her husband took work in another city. “I always wanted to run a small shop,” she says. “But I wasn’t allowed to have money of my own, I didn’t have the resources to be an entrepreneur.” In 2016, women represented less than 5 percent of the formal workforce in Jind’s state of Haryana.

Today, her life looks different. “I look for high-quality cloth in the market. I look up new trends on YouTube and learn to stitch different designs,” she says. Her clothes sell at a premium. “In the village, I would earn about 200 rupees (less than $3) per dress. In the market, my designs sell for 450 to 750 rupees ($6 to $10),” she says.

In April, during the pandemic-induced lockdown, Katariya created a WhatsApp group of friends and acquaintances. “If I saw an interesting video, I would share it with the group and take preorders,” she said. Katariya created a visual catalogue and built inventory in anticipation of a future uptick in demand, especially towards the end of the year. “Now, with the festival season, my business is picking up again,” she says. Being internet savvy has given her both credibility and a larger social network in Jind. “If anyone who doesn’t have a phone needs to look something up, they come to me,” she says.

Service can be spotty, as India’s 700 million cell phone users compete for limited bandwidth. Katariya often must wait for videos to buffer. Mallika has to go to specific spots in the forest to use her phone. The Indian government is working to upgrade the networks, which will also make it easier for millions of women to learn, earn, shop, argue, resist, and talk in a society that often micromanages their lives.
