Though Meta didn’t give numbers on RSC’s current top speed, in terms of raw processing power it appears comparable to the Perlmutter supercomputer, ranked fifth fastest in the world. At the moment, RSC runs on 6,800 NVIDIA A100 graphics processing units (GPUs), a specialized chip once limited to gaming but now used more widely, especially in AI. Already, the machine is processing computer vision workflows 20 times faster and large language models (like, GPT-3) 3 times faster. The more quickly a company can train models, the more it can complete and further improve in any given year.

In addition to pure speed, RSC will give Meta the ability to train algorithms on its massive hoard of user data. In a blog post, the company said that they previously trained AI on public, open-source datasets, but RSC will use real-world, user-generated data from Meta’s production servers. This detail may make more than a few people blanch, given the numerous privacy and security controversies Meta has faced in recent years. In the post, the company took pains to note the data will be carefully anonymized and encrypted end-to-end. And, they said, RSC won’t have any direct connection to the larger internet.

To accommodate Meta’s enormous training data sets and further increase training speed, the installation will grow to include 16,000 GPUs and an exabyte of storage—equivalent to 36,000 years of high-quality video—later this year. Once complete, Meta says RSC will serve training data at 16 terabytes per second and operate at a top speed of 5 exaflops.

SpaceX’s Starship will be a multipurpose launch vehicle, capable of returning astronauts to the Moon to build a permanent base and enabling humanity to build a sustainable colony on Mars. It is expected to become the world’s most powerful rocket-ship. “Starship was designed from the onset to be able to carry more than 100 tons of cargo to Mars and the Moon. The cargo version can also be used for rapid point-to-point Earth transport. Various payload bay configurations are available and allow for fully autonomous deployment of cargo to Earth, Lunar, or Martian surfaces,” the company said.

SpaceX’s Starship launch vehicle has many potential uses and capabilities that will enable access to space like never before. The cargo version of Starship will be able to launch entire satellite constellations in a single launch inside its payload bay. For perspective, SpaceX’s Falcon 9 can carry up to 60 Starlink in a tight configuration inside its 5.2-meter diameter fairing, Starship will be able to carry 400 Starlink to deploy in a single launch inside its fairing. Starship will be capable of deploying giant spacecraft to space inside its clamshell-like fairing, which has an outer diameter of 9-meters –“the largest usable payload volume of any current or in development launcher,” the company says. SpaceX also plans to design an extended Starship volume capability for payloads requiring up to 22-meters of height.

Starship will also be able to capture already in orbit to be repaired or brought back to be disposed of on Earth, according to SpaceX’s Starship User Guide. “Fully-reusable Starship and Super Heavy systems are expected to allow for space-based activities that have not been possible since the retirement of the Space Shuttle and Space Transportation System, or have never been possible before. With a fully reusable Starship, can be captured and repaired in Orbit, returned to Earth, or transferred to a new operational orbit,” SpaceX’s vehicle guide says. This will be possible with Starship’s large clamshell-like cargo door mechanism that opens and closes, as shown in the image below. The clamshell door can be modified to “chomp up” old and space junk orbiting Earth. “We can fly Starship around space and chomp up debris with the moving fairing door,” SpaceX founder Elon Musk said in July 2021.

By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying signals cannot be amplified or relayed through classical optical methods to maintain quantum security. The resulting transmission loss of the channel can limit its achievable distance to form a huge barrier to build large-scale quantum secure networks. In a new report now published in Nature Photonics, Shuang Wang and a research team in quantum information, cryptology and quantum physics in China developed an experimental QKD system to tolerate a channel loss beyond 140 dB across a secure distance of 833.8 km to set a new record for fiber-based quantum key distribution. Using the optimized four-phase twin-field protocol and high quality setup, they achieved secure key rates that were more than two orders of magnitude greater than previous records across similar distances. The results form a breakthrough to build reliable and terrestrial quantum networks across a scale of 1,000 km.

Quantum cryptography and twin-field quantum key distribution (QKD)

Quantum key distribution is based on fundamental laws of physics to distribute secret bits for information-theoretic secure communication, regardless of the unlimited computational power of a potential eavesdropper. The process has attracted widespread attention in the past three decades relative to the development of a global quantum internet, and matured to real-world deployment through optical-fiber networks. Despite this, wider applications of QKD are limited due to channel loss, limiting increase in the key rate and range of QKD. For example, photons are carriers of quantum keys in a QKD setup, and they can be prepared at the single-photon level to be scattered and absorbed by the transmission channel. The photons, however, cannot be amplified, and therefore the receiver can only detect them with very low probability. When transmitted via a direct fiber-based link from the transmitter to the receiver, the key rate can therefore decrease with transmission distance.

The Guardian reports that the case revolves around George Defteros, a Victoria defense lawyer who previously represented Melbourne gangland figures. He sued Google over claims that its publication of search results showing a 2004 article defamed him.

The article from The Age implied that Defteros had become more than just a lawyer for criminal elements but was also a friend and confidant, crossing professional boundaries. The piece also reported on the murder charges Defteros faced in relation to the killing of three men. Prosecutors withdrew the charges in 2005.

A Facebook robot that wraps fiber-optic cable around existing power lines could help bridge the digital divide by bringing internet access to some of the billions of people who currently lack it.

Why it matters: The 60% of the world population with internet access has social, economic, financial, and educational advantages over the other 40%, most of whom live in developing nations or rural areas.

The cost of expanding internet networks is a major barrier to bringing internet access to those people — if the Facebook robot can cut that cost, it could help close this “digital divide” and make the world a more equitable place.

The more a technology or concept permeates and gets normalized in our day-to-day lives, the more we grow to expect from it. About two decades ago, a sub-56kpbs dial-up internet connection seemed miraculous. Today, with internet speeds as high as 2000Mbps becoming normal, the 56Kbps connection would be considered a failure of sorts—in the developed world, at least. This shift in expectation also applies to AI. Having seen numerous practical AI applications aid human convenience and progress, both the general population and the AI research community now expects every new breakthrough in the field to be more earth-shattering than the previous one. Similarly, what qualifies as AI failure has also seen a massive shift in recent years, especially from a problem owner’s perspective. failure, in most cases, is attributed to technology-centric factors like the quality of data or the capabilities of algorithms and hardware used, ignoring the most crucial aspect of AI success—the end user.

It is clear to see that the variety of businesses, individuals, and entities that could potentially operate in the metaverse is vast. The widespread use and acceptance of decentralization through the growth of crypto, NFTs, and DeFi point to a fully-realized future operating outside of the parameters of today’s established markets.

Evidently, therefore, the metaverse is not a sci-fi fantasy conjured up in a dystopian novel, but a more tangible and natural progression for the current structuring of the internet. The founding principles of the metaverse have already been introduced in many ways. Now its development centers on blockchain technology and DeFi to propel it from the conceptual stage towards the implementation phase. This development will allow us to firmly realize the true extent that the metaverse will impact our lives.

The gaming industry is one such sector that stands to benefit greatly from developments arising in the metaverse. Gaming skins, which are in-game avatar outfits, are expected to trade at a level of $40 billion every year. Eighty-one percent of players aware of these skins want to trade them for real-world money, according to a report from DMarket. Currently, there is no method of transferring skins across gaming universes or trading them for currency. In the metaverse, however, as every separate gaming universe is connected through a decentralized economy, this would be possible. The use of metaverse-based banks would also enable transactions like these.

We will soon need to make some difficult choices.

Given current trends, that number will be reached within a year or so. There are ways to mitigate the effect of these streaks. Painting the satellites and adding reflective panels could reduce their brightness, particularly at infrared wavelengths that are important for near-Earth asteroid detection.

But the study points out that the mitigation strategy currently proposed by Starlink won’t be sufficient to avoid an impact on astronomy.

Say goodbye to that buffering wheel.

The next generation of Wi-Fi is just around the corner.

Taiwan-based semiconductor firm MediaTek successfully conducted the first-ever live demo for Wi-Fi 7 technology, according to a report from DigitalTrends. The company also stated that it expects Wi-Fi 7 products to become available next year in anticipation of the launch of the next-gen Wi-Fi sometime around 2024.
