FW: Tesla Computer Hardware Stuns Competitors: “We Cannot Do It”

https://futurism.com/the-byte/tesla-computer-hardware-stuns-competitors Tesla Computer Hardware Stuns Competitors: “We Cannot Do It” Teardown Japanese business newspaper Nikkei Asian Review recently conducted <https://asia.nikkei.com/Business/Automobiles/Tesla-teardown-finds-electroni…> a teardown of a Tesla Model 3, and engineers were shocked at how advanced the electric car company’s onboard computer technology was. “We cannot do it,” an unnamed Japanese engineer at a rival car company said after analyzing the Model 3’s integrated central control unit, as quoted by Nikkei — referring to legacy automakers’ inability to catch up to Tesla’s AI chips. Next Gen The current generation of Tesla’s “Hardware 3” chips, which it started installing in vehicles last year, have enough computational power to enable Tesla vehicles to fully drive themselves, <https://techcrunch.com/2019/10/23/elon-musk-says-tesla-early-access-full-se…> according to CEO Elon Musk. But as of right now, Tesla’s fleet’s self-driving capabilities are limited to Level 2 — out of five, in which level 5 is fully autonomous — or “partially autonomous.” That means they’re able to handle things like changing lanes, making turns, and navigating parking lots without a driver in the seat. Six Years Ahead Nonetheless, according to Nikkei, the rest of the industry is expecting the same level of technology to make it into cars no sooner than 2025, prompting experts to suggest Tesla is a full six years ahead of the competition. The hold up, according to Nikkei, is likely related to established automakers’ legacy supply chains. Tesla is a newer company that can choose its partners more freely, in other words, effectively leapfrogging the competition.

MacBooks may be in short supply after March | Cult of Mac
by Dejan Ristanovic 17 Feb '20

https://www.cultofmac.com/685297/macbook-shortage-coronavirus-quanta/ MacBooks may be in short supply after March Ed Hardy10:40 am, February 17, 2020 The coronavirus outbreak means it isn’t a good time to procrastinate on a MacBook purchase. Photo: Apple Now might be the best time to buy that MacBook you’ve been considering. Factory shutdowns in China because of the coronavirus outbreak will reportedly lead to shortages of components needed to make laptops. Quanta, the company that assembles MacBooks, is ramping up notebook production in Taiwan, according to Digitimes. It’s allegedly using these facilities to make products for a variety US companies. But moving production to its home country might not save Quanta completely from the effects of COVID-19, the disease which has so far killed 1,770 people in China. Laptop makers are reportedly going to start running out of Chinese-made components they need by the end of this month. There are already possible signs of shortages. Those ordering some custom-configured MacBooks face wait times of over a month. Coronavirus hurts the entire notebook market To be clear, it won‘t just be Apple that might be facing shortages. Quanta assembles products for Dell, HP, Lenovo and many other companies. The Chinese government has ordered many businesses — including laptop manufacturers — to close as part of its efforts to stop the further spread of a pneumonia-like illness that has struck over 71,000 people in China. As a result, Digitimes Research predicts notebook shipments worldwide will drop 29% to 36% sequentially this quarter. That said, this is traditionally a slow time of the year for sales, so shipments were already expected to drop 17% before the outbreak. Sent from my iPad 2018

Ups... https://www.theregister.co.uk/2020/02/13/iana_dnssec_ksk_delay/ Internet's safe-keepers forced to postpone crucial DNSSEC root key signing ceremony – no, not a hacker attack, but because they can't open a safe Online security process stalled by offline security screw-up By <https://www.theregister.co.uk/Author/Kieren-McCarthy> Kieren McCarthy in San Francisco 13 Feb 2020 at 06:09 The organization that keeps the internet running behind-the-scenes was forced to delay an important update to the global network – because it was locked out of one of its own safes. “During routine administrative maintenance of our Key Management Facility on 11 February, we identified an equipment malfunction,” explained Kim Davies, the head of the Internet Assigned Numbers Authority ( <https://www.iana.org/about> IANA), in an <https://mm.icann.org/pipermail/root-dnssec-announce/2020/000121.html> email to the dozen or so people expected to attend a quarterly ceremony in southern California at lunchtime on Wednesday. The malfunction “will prevent us from successfully conducting the ceremony as originally scheduled" on February 12, Davis explained. “The issue disables access to one of the secure safes that contains material for the ceremony.” In other words, IANA locked itself out. The ceremony sees several trusted internet engineers (a minimum of three and up to seven) from across the world descend on one of two secure locations – one in El Segundo, California, just south of Los Angeles, and the other in Culpeper, Virginia – both in America, every three months. Once in place, they run through a lengthy series of steps and checks to cryptographically sign the digital key pairs used to secure the internet’s root zone. (Here's <https://www.cloudflare.com/dns/dnssec/root-signing-ceremony/> Cloudflare's in-depth explanation, and IANA's <https://data.iana.org/ksk-ceremony/40/20200212-KC40_Ceremony_Script.pdf> PDF step-by-step guide.) At the heart of the matter, simply put, is the Key Signing Key (KSK): this is a public-private key pair, with the private portion kept locked away by IANA. This is because the KSK is used, every three months, to sign a set of Zone Signing Keys, which are used to secure official copies of the internet's root zone file. That file acts as a kind of directory for other parts of the internet, and these parts in turn, provide information on more of the internet. It is, in a way, the blueprint for how the internet as we know it is glued together: how domain names resolve to computers on the global network, so that when you visit, say, theregister.co.uk, you eventually reach one of our servers at network address 104.18.235.86. Critical root DNS servers are spread out around the planet, each armed with a copy of the latest signed root zone file, and used, in a distributed, cascading manner, by other DNS servers to look up domain names for the internet's users. These servers can check the root zone file underpinning all of this is secured by a ZSK recently signed by the central IANA KSK, and thus can be treated and trusted as gospel. The KSK is thus the domain-name system's trust anchor. Everything relies on it to ensure the 'net's central directory is laid out the way it should be, according to IANA, anyway. This is all necessary because it should be immediately obvious whether or not a root zone file is an unsigned forgery, or an authentic and clean copy secured by IANA's KSK. Otherwise, a well-resourced malicious organization could potentially fool networks into using a sabotaged root zone file that redirects vast quantities of traffic, i.e. billions of internet users, to different parts of the internet. Even worse, if someone were to get hold of the KSK, they could sign their own zone file and have the internet blindly trust it. The result would be a global loss of trust in the 'net's functioning. Security up the wazoo For that reason, IANA takes its Root Key Signing Key Ceremony extremely seriously, and has a <https://www.iana.org/dnssec/icann-dps.txt> complex and somewhat convoluted DNSSEC-based <https://www.iana.org/dnssec> process that briefly unlocks the private portion of the KSK to sign the ZSKs every three months. Only during this ceremony is the KSK used, and put away again when it is over, leaving IANA with a set of ZSKs to authoritatively secure its root zone. Only specific named people are allowed to take part in the ceremony, and they have to pass through several layers of security – including doors that can only be opened through fingerprint and retinal scans – before getting in the room where the ceremony takes place. Staff open up two safes, each roughly one-metre across. One contains a hardware security module that contains the private portion of the KSK. The module is activated, allowing the KSK private key to sign keys, using smart cards assigned to the ceremony participants. These credentials are stored in deposit boxes and tamper-proof bags in the second safe. Each step is checked by everyone else, and the event is <https://www.youtube.com/watch?v=erfsFJsapAs> livestreamed. Once the ceremony is complete – which takes a few hours – all the pieces are separated, sealed, and put back in the safes inside the secure facility, and everyone leaves. <https://www.theregister.co.uk/2019/10/28/arin_rpki_open_source/> <https://www.theregister.co.uk/2019/10/28/arin_rpki_open_source/> You're ARIN a laugh: Critical internet org accused of undercutting security over legal fears <https://www.theregister.co.uk/2019/10/28/arin_rpki_open_source/> READ MORE But during what was apparently a check on the system on Tuesday night – the day before the ceremony <https://www.iana.org/dnssec/ceremonies/40> planned for 1300 PST (2100 UTC) Wednesday – IANA staff discovered that they couldn’t open one of the two safes. One of the locking mechanisms wouldn’t retract and so the safe stayed stubbornly shut. As soon as they discovered the problem, everyone involved, including those who had flown in for the occasion, were told that the ceremony was being postponed. Thanks to the complexity of the problem – a jammed safe with critical and sensitive equipment inside – they were told it wasn’t going to be possible to hold the ceremony on the back-up date of Thursday, either. We understand, however, that following an emergency meeting on Wednesday, the issue should be fixed by Friday, and the ceremony has now been moved to Saturday. In the meantime, some lucky locksmith in Los Angeles is going to have to drill out the safe’s locking mechanism and put in a new one. Fortunately, apart from the inconvenience, there is no impact on the internet itself, particularly in this short term. The current arrangement will simply continue to do its job for three additional days. And IANA has been keen to point out that it has an identical set of equipment on the other coast of the US that can also be used if necessary. “We apologize for the inconvenience for the attendees who had already traveled to participate in the ceremony. This is the first time a ceremony has needed to be rescheduled in the 10-year history of KSK management,” the email announcing the delay noted. There is a certain irony, of course, that the security of the virtual internet has been held hostage by an old-school physical safe. ® Sponsored: <https://go.theregister.co.uk/tl/1877/shttps:/mcubed.london/?utm_source=ther…> M3 - The ML, AL and Analytics Conference from The Register Sent from my iPad 2018

https://www.independent.co.uk/life-style/gadgets-and-tech/news/internet-spee d-fast-cable-wires-terahertz-quantum-cascade-lasers-a9328691.html CABLES 1,000 TIMES FASTER THAN CURRENT INTERNET WIRES COULD BE CREATED AFTER MAJOR BREAKTHROUGH Andrew Griffin Data could be transmitted a thousand times faster than current internet cables after a major breakthrough, scientists have said. The new research uses terahertz quantum cascade lasers that could send data around the world at speeds unimaginable using current technology. The lasers could be used to vastly speed up data communications, according to the researchers behind the study, which is published today in the journal Nature Communications. The study saw researchers make a breakthrough in the control of terahertz quantum cascade lasers, which they say could be used to transmit data at a speed of 100 gigabits. Current - very fast - ethernet connections work at 100 megabits a second, a thousand times less quick. The specific kind of lasers are different because they send out light in the terahertz range of the electromagnetic spectrum, which is largely used to analyse chemicals. But by turning them to use to send data, they could provide much faster connections for research facilities, hospitals, satellite communications or any other situations where very fast network connections are required. To be used to send to data, the lasers need to be switched off about 100 billion times every second. That requires precise control, and engineers have so far been unable to do it. Now researchers think they have found a way of controlling that very fast modulation, using sound and light. "This is exciting research," said John Cunningham, Professor of Nanoelectronics at Leeds. "At the moment, the system for modulating a quantum cascade laser is electrically driven - but that system has limitations. "Ironically, the same electronics that delivers the modulation usually puts a brake on the speed of the modulation. The mechanism we are developing relies instead on acoustic waves." When an electron passes through the optical part of the laser, it travels through a host of "quantum wells" that throw out a pulse of light energy. An electron can emit a number of those photons, and that is controlled - using soundwaves to vibrate those quantum wells - in the new experiment. "Essentially, what we did was use the acoustic wave to shake the intricate electronic states inside the quantum cascade laser," said Tony Kent, Professor of Physics at Nottingham. "We could then see that its terahertz light output was being altered by the acoustic wave." The research is not perfect, and more control is still needed before the lasers could be used reliably to transmit data. But with further work they could lead to major breakthroughs in transmitting data. "We did not reach a situation where we could stop and start the flow completely, but we were able to control the light output by a few percent, which is a great start," said Professor Cunningham. "We believe that with further refinement, we will be able to develop a new mechanism for complete control of the photon emissions from the laser, and perhaps even integrate structures generating sound with the terahertz laser, so that no external sound source is needed."
