Moke International makes the car in Britain before final assembly in France. The revised chassis has been re-engineered to accommodate four passengers, and look for an all-electric version to be released in the summer. Priced from around $30,000, the Moke can be customized with a choice of 13 colors, including eye-popping Flamingo Pink and Florida Orange. My tester also wears gleaming chrome trim and badging on the hood.

Other stylistic touches include leather hood straps and a retro radio, which is actually able to be heard above the wind noise, at least at speeds below 45 mph. And on a wet day, with weather equipment in place, the windscreen can be heated for improved visibility. In all, this upgraded version is not far off from Sir Alec’s initial car—basic in the extreme and as quintessentially British as fish and chips or a warm pint of beer.

Accordingly, it is reportedly telling customers how to bypass its “genuine” ink bullshit. (translation)

We value you as a customer and a constant user of Canon products. Due to the persistent global shortage of semiconductor components, Canon is currently facing challenges in sourcing certain electronic components that are used in our consumables for our multifunction printers (MFP). These components lead e.g. B. Features such as the detection of the remaining toner level. In order to ensure a continuous and reliable supply of consumables, we have decided to deliver consumables without semiconductor components until normal supply is restored. There is no negative impact on print quality when using consumables without electronic components, but certain additional functions, such as e. B. the detection of the toner level may be impaired.

The instructions appear to be straightforward—for the models I checked all you have to do is ignore onerous error messages—so it seems incorrect to claim Canon blocks the use of third-party cartridges. HP’s ink DRM is clearly more despised —they not only block non-DRM ink, but the ink is region locked and they expect you to pay for and maintain a subscription to it.

According to 热心市民描边怪 “Enthusiastic Citizen”, a tech leaker known from Bilibili and Chiphell social platforms, AMD is now preparing its new series of Ryzen processors for launch. Those should be considered a direct response to the just-released Intel Alder Lake non-K series.

It goes without saying that AMD is in trouble with its low-end to mid-range products. With the release of 65W Alder Lake CPUs, the blue team took the indisputable lead in the cheap processor segment, often offering better performance than AMD’s more expensive 6-core CPUs. AMD is in a tough spot because the company did not launch any quad-core Ryzen 5,000 series on Vermeer silicon, only on Cezanne but even those are hard to come by (Ryzen 3 5300G is OEM only). There were also Ryzen 5,000 PRO series but those are not targeted at consumers.

A group of scientists at the U.S. Department of Energy’s Ames Laboratory has developed computational quantum algorithms that are capable of efficient and highly accurate simulations of static and dynamic properties of quantum systems. The algorithms are valuable tools to gain greater insight into the physics and chemistry of complex materials, and they are specifically designed to work on existing and near-future quantum computers.

Scientist Yong-Xin Yao and his research partners at Ames Lab use the power of advanced computers to speed discovery in condensed matter physics, modeling incredibly complex quantum mechanics and how they change over ultra-fast timescales. Current high performance computers can model the properties of very simple, small quantum systems, but larger or more complex systems rapidly expand the number of calculations a computer must perform to arrive at an accurate model, slowing the pace not only of computation, but also discovery.

“This is a real challenge given the current early-stage of existing quantum computing capabilities,” said Yao, “but it is also a very promising opportunity, since these calculations overwhelm classical computer systems, or take far too long to provide timely answers.”

For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. Achieving this, however, has come at the cost of size. Whereas the transistors used in classical computers have been shrunk down to nanometer scales, superconducting qubits these days are still measured in millimeters—one millimeter is one million nanometers.

Combine qubits together into larger and larger circuit chips, and you end up with, relatively speaking, a big physical footprint, which means quantum computers take up a lot of physical space. These are not yet devices we can carry in our backpacks or wear on our wrists.

To shrink qubits down while maintaining their performance, the field needs a new way to build the capacitors that store the energy that “powers” the qubits. In collaboration with Raytheon BBN Technologies, Wang Fong-Jen Professor James Hone’s lab at Columbia Engineering recently demonstrated a superconducting qubit built with 2D materials that’s a fraction of previous sizes.

MIT physicists and colleagues have discovered the “secret sauce” behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include superconductivity. Although theorists had predicted the reason for the unusual properties of the material, known as a kagome metal, this is the first time that the phenomenon behind those properties has been observed in the laboratory.

“The hope is that our new understanding of the electronic structure of a metal will help us build a rich platform for discovering other ,” says Riccardo Comin, the Class of 1947 Career Development Assistant Professor of Physics at MIT, whose group led the study. That, in turn, could lead to a new class of superconductors, new approaches to quantum computing, and other quantum technologies.

The work is reported in the January 13, 2022 online issue of the journal Nature Physics.

My Chapter Titled ‘’, has been published in ‘Handbook of Real-Time Computing’ in Springer Nature. The chapter provides information on satellite communication networks for different orbits, use-cases, scenarios, link budget analyses, history, and future developments.

Software-defined radio (SDR) is one of many new technologies being adopted by satellite communication to lower the costs both operational and capital by reducing the amount of radio equipment involved in the communication chain and by giving the advantage of remote configuration and regular firmware updates. SDR basically replaces most of the radio equipment by a single computing device with software capable of performing functions of the replaced hardware equipment. SDRs are introduced not only in terrestrial gateways and ground stations, but next generations of LEO and GEO satellites are already adopting the technology. Previously, satellite radio links were limited to the configuration of radio equipment that was installed during the manufacturing of the satellite, which couldn’t be modified throughout the lifespan of the satellite.

Figure 15 displays a generic digital communication transmit and receive RF chain at the physical layer for binary, sampled, and analogue data streams. Data in binary that is collected from data source at transmit end is coming from the higher layers, which is then coded in binary, modulated to sampled, converted to analogue waveform through digital to analogue converter before sending it to the antenna end for transmission over-the-air interface with required transmit power. At the receive end, the wireless signal is received as analogue, converted to sampled for demodulation, decoded to binary, and sent to data sink for integrating with upper layers. The coding/decoding and modulation/demodulation, commonly referred to as MOD/COD, are programmable functions and can be replaced by SDR using a processing device. This can be done at the ground stations, at the gateway, user terminals, and at the satellite using on-board processing.

The metaverse, which requires a massive amount of computing power, is set to benefit global chipmakers— but other tech-related industries could also gain from it, analysts say.

Widely seen as the next generation of the internet, the metaverse refers broadly to a virtual world where humans interact through three-dimensional avatars that can be controlled via virtual reality headsets like Oculus.

Through the metaverse, users can engage in virtual activities such as gaming, virtual concerts or live sports.
