The Sidewalk was announced by Amazon in 2019 and ready to launch in the middle of next month. Photo: Amazon This is a project that Amazon has been researching and developing for years, it was first announced in 2019. Amazon Sidewalk will connect things like yard lights, pet trackers, or sensors on mailboxes. Sidewalk’s aim is to provide wireless infrastructure for these devices by turning Amazon devices like Echo speakers into connection points that any Sidewalk-enabled device can use. Amazon will use Sidewalk’s low-energy bluetooth connections as a home wifi backup network. On the Echo front, Amazon plans to take advantage of Sidewalk’s low-energy Bluetooth connections as a backup network for your home wifi, which means better stability during device setup and Reconnect to the router faster when you update the network name or password. Amazon says that Sidewalk is expected to support multiple wireless protocols such as Bluetooth Low Energy, Lora low-bandwidth protocol in the 900 MHz band and others, opening the network to more third parties while providing the ability to connectivity and better battery life. Developer LoRa Semtech Corp. said they are partnering with Amazon on the Sidewalk initiative. The combination of Amazon and Tile tracking company to expand Tile’s search network for Find with Tile devices and device partners leverages search technology. Customers can rely on Tile trackers in conjunction with Amazon Sidewalk to find related items such as for money, other keys, or everything.

An Amazon pilot program will combine Sidewalk’s long-range connectivity with CareBand technology to support features such as indoor and outdoor activity tracking, help buttons, and automated analysis of samples. work. The biggest problem with Amazon Sidewalk is privacy and security, many questions are posed and which Amazon answered that, Sidewalk is built to keep your data safe and give you control. my experience. Data shared over the Sidewalk network is protected with three layers of encryption, accessible only to the devices you choose, and automatically deleted every 24 hours to protect your privacy. Amazon Sidewalk will launch on June 8, users do not have to upgrade hardware from selected devices such as the 2nd generation, 3rd generation spherical Amazon Echo, Amazon Echo Show 10, Ring Floodlight Cam and session The Ring Spotlight Cam is wired and many more, but there are no Eero devices that Amazon purchased in 2019 on this list. Most recently Apple introduced to consumers the Apple AirTag device with a small circular design to track forgotten devices such as keys or wallets, they will be tracked in My Find on iOS, it is for is a feature similar to Tile and will be a direct competitor to the tracking technology firm.

He added that the Abel Prize (considered the Nobel Prize for Mathematics) in 2021 was awarded to a pioneer in the field Zero Knowledge Proof – Scientist László Lovász (Mathematical Institute Alfréd Rényi and University of Eötvös Loránd in Budapest, Hungary), and Avi Wigderson (Institute for Advanced Study in Princeton, USA). The puzzle is as follows: Isla works in an office with 100 employees. One day, she discovered that her favorite paperclip was stolen by someone else. She identifies the suspicious object. Annabel, her colleague, said she was also suspicious of a person. Isla wants to know if she and Annabel are suspicious of the same person, but the two don’t want the other to know who they are doubting, in case they suspect different subjects. Isla thinks over and over how she and Annabel can check if they suspect the same person without revealing the information they find suspicious to the other party. The question is whether Isla and Annabel can find a way to reconcile their thoughts without letting the other know who they are doubting? This method should ensure that, after comparison, Isla knows whether she and Annabel are suspicious of the same person. Second, they need to make sure the other person doesn’t know they are distrusting. This verification is part of the protocol Zero-knowledge . At first glance, Alex Bellos judged that this was a puzzle without a solution. For example, Isla cannot say “The person I suspect was late for work on Monday” because it revealed some information about the other person. He also came up with a third party two-man solution, Dan, a good friend they trust a lot. Then, Isla and Annabel numbered the office staff from 1 to 100. Next, they write the number to replace the name of the suspect on a piece of paper and give it to Dan. If Dan confirms the two numbers are the same, they suspect the same person and vice versa. However, this solution is not perfect as no one can guarantee Dan from disclosing his number to the other person. Everything depends on the level of trustworthiness of the third party. Therefore, it cannot guarantee the non-disclosure of information as the quiz requires. Nearly 200 people participated in discussing Alex Bellos’s riddle and proposing measures to verify that Isla and Annabel were suspicious of the same person. Then, the author Alex Bellos together gave 3 relatively suitable methods. Can you take any measures to ensure the request of the assignment or not, ie Isla and Annabel know if they are suspicious of the same person and do not disclose information about the suspect to the other person?

New cryptocurrency – Chia coin, also known as “Green Bitcoin”, was created by Bram Cohen, who is famous for his peer-to-peer BitTorrent protocol. Hard drive fever from Chia The popularity of cryptocurrencies like Bitcoin has led to a shortage of graphics cards when miners buy them in bulk. Now, Split coin – a new cryptocurrency set to create another component shortage, this time hard drives and SSDs will become hard to find. The increase in GPU supply will occur this quarter, said Nvidia Chief Financial Officer Colette Kress, a multinational corporation for graphics processor development. So with any luck, the products might be a bit easier to buy in the coming weeks and months. “ The problem faced by the market was crypto miners who bought GPUs. In response, Nvidia released a line of dedicated mining graphics cards called CMP, which professional cryptocurrency miners are starting to buy. ”Kress said. The new cryptocurrency – Chia coin, also known as “Green Bitcoin”, was created by Bram Cohen, who is famous for his peer-to-peer BitTorrent protocol development. According to the report, Chia used Bitcoin’s “proof of work” model instead of Bitcoin’s “proof of work” model. That difference means Chia is dependent on storage capacity rather than processing efficiency to mine, and a lot less electricity is wasted in the process. While Chia hasn’t been traded yet, it looks like potential miners in China are gearing up by buying as many hard drives and SSDs as possible, all drives from 4TB to 18TB in high demand. Prices are expected to rise and shortages are likely to be seen unless manufacturers react quickly enough to keep up. On China’s Taobao and JD.com e-commerce platforms, many large-capacity enterprise-class hard drives have been sold out. According to Jiahe Jinwei, one of the major domestic manufacturers in China, the Gloway and Asgard’s 1TB and 2TB high-performance NVMe M.2 SSDs have both been sold out. The manufacturer plans to put in place restrictions to prevent miners from buying large amounts of consumer SSDs. After that, the company will also increase production to meet demand. “ Farming on consumer SSDs is feasible, but more serious miners will likely be geared toward the business side. Durability is just as important as capacity and performance, and enterprise or data center SSDs often meet these three criteria. ”, Said Jiahe Jinwei. Back in 2018, Chia raised $ 3.395 million in “seed” funding, which demonstrated a great degree of interest in this new cryptocurrency. For the most part, that interest could be from investors expecting them to see the potential early and invest a lot when it first arrives. Along with that, many cryptocurrencies appeared and collapsed, so the formation and development of Chia also caused curiosity among the crypto participants. A few years ago, no one took Bitcoin seriously and today it has reached a value of over $ 65,000 / BTC. Cryptocurrency mining itself is the process by which a machine performs certain tasks, calculations validating transactions on the platform, and enhanced security, in order to obtain an amount of cryptocurrency. As a reward to miners for using their hardware to service network transactions, they charge transaction fees for the transactions they confirm. Although Chinese law does not recognize Bitcoin as a legal currency, the country does not completely ban Bitcoin mining. Even this billion-population country accounts for about 70% of bitcoin blockchain operations worldwide. The surge in electricity consumption related to cryptocurrency mining has also attracted the attention of Chinese regulators, amid the country’s efforts to save energy and reduce pollution. Inner Mongolia is a major bitcoin producer in northern China due to cheap electricity prices, saying it will close all bitcoin mining sites before May this year. Is there an abnormality? In addition to the hard drive craze, computer storage space has become a hot commodity lately, with protocols like Filecoin and Filebase rolling out to take advantage of unused storage. It seems that Chia is not without its drawbacks as some have tested and criticized its energy efficiency and pointed out that the rewards take 5 months to come true. Dividing into storage space rather than processing efficiency to mine and known as “green Bitcoin” is creating a hard drive race in Southeast Asia. Blockchain critic David Gerard warns that the reported shortage could have a direct impact on the cryptocurrency market and other industries. However, the project is going on an unusual path. Split no limit, prioritize constant inflation, is predictable as an alternative and the company has a cache of 21 million Pre-mined Chia. And while “spatial proof” is meant to strengthen decentralization, it’s a goal that Chia will not track for itself, rather, it will be made public. Besides that, a roster will allow proponents to treat Chia’s equity as a Chia coin ETF, using the 21 million Chia coin as the primary asset. Talking to the Business Forum, Mr. Dinh Hong Son, General Director of the new generation Finance Joint Stock Company, said that Chia is a digital currency that has appeared since 2018 but has not created a fever like today. The fever that the market is feeling is not the currency, but the market for the hard drives. In fact, large corporations in the world like Intel still do not show signs of “flinching” for shortages, maybe this is just one of the waveforms to push Chia’s appeal against the blur. its pale. “ This is also easy to cause local reactions, as many manufacturers tend to want to take short cuts by increasing production. While in the field of electronics, electronic components require many supporting details that must be processed in large quantities to ensure production as well as reasonable prices. Therefore, it is not known how sustainable or how long-term Chia is to be, but focusing on large-scale production can pose a risk to manufacturers. Hopefully, any impact on consumption patterns will be short-lived “, Mr. Son said. Currently, Chia has not appeared in Vietnam, but it is also necessary to observe and monitor this coin to avoid following the trend like the past Pi mining phenomenon. In particular, electronic component manufacturers or merchants avoid the “hugging” too large for hard drives or products with storage capacity, and at the same time push the prices of goods higher than their value. real.

Chemotherapy Illustration. Not all chemotherapy causes eyebrow hair loss. There is usually a standard protocol that if you don’t lose your hair, you will lose your eyebrows. Infection If you have a fungal infection, scabies, syphilis and leprosy, your eyebrows will fall out from scratching a lot. Autoimmune disorders This causes hair loss all over the body, including the eyebrows. Immune disorders that cause brow loss include symptoms like lupus that can cause thinning of eyebrows and hair loss. Vitiligo can sometimes cause inflammation that is severe enough to cause hair loss and hair loss. In general, eyebrow hair loss often occurs with other symptoms more severe when lupus and vitiligo visit. Onions and honey to thicken eyebrows In onion contains a lot of sulfur, a compound that stimulates hair growth, enhances blood circulation very effectively. Honey contains many important vitamins that support the growth of eyebrows. Materials need to prepare: – 1/3 onions 1/2 teaspoon honey – Blender, sieve, bowl and spoon The ingredients you need to prepare Doing: – Onions peeled, washed, sliced ​​and then put in a blender, puree.

China’s test network connects 40 top universities in preparation for a society powered by artificial intelligence (Image: Shutterstock) Located at Tsinghua University, “Future Internet Technology Base” connects 40 universities, the country’s leading research institute with much lower bandwidth and latency than the current Internet. ; According to the Xinhua state news agency. This facility will serve as the “backbone” for the China Network Innovation Environment (CENI) – a research facility linking the largest cities in China – to confirm the effectiveness and safety of the public. network technology in the future before bringing it into commercial use. When completed in 2023, the CENI facility will become a prototype of the “Internet of the Future”, connecting almost everything – from home computers to cars on the street – to serve information without compromise. disruption in a society powered by artificial intelligence (AI). “We will put a lot of effort into it. The Internet of the future needs to withstand all kinds of attacks. It is important to our national security, ”an anonymous computer scientist who was involved in the project at Tsinghua University told SCMP. China’s current Internet is built with Western technology and is full of backdoors. The US government’s Prism project, for example, took advantage of these weaknesses to penetrate the Chinese government and some of its research institutes, including Tsinghua; according to “whistleblower” Edward Snowden. Following Snowden’s revelation, the Beijing government has stepped up efforts to replace Western hardware in its information infrastructures. In recent years, a number of Chinese telecom companies, including Huawei Technologies Co., have outperformed Western firms in 5G network development and many other technologies. But their lead is limited to certain areas, while foreign software and protocols still prevail in the Chinese network. The US government has also launched a multitude of test networks, including the Global Network Innovation Environment (GENI) to maintain their leadership position in networking technology. Other players – such as the EU, Japan and South Korea – have also started similar projects. According to Tan Hang, the lead scientist working on the CENI project, the construction of the Chinese test network began in 2019. China’s base is to counter the US GENI program, with completely different technology. For example, China will develop a brand new operating system to manage data flow and “conversation”. between devices on the future Internet network, with the support of domestically produced hardware – from routers, servers to computer chips…, according to Mr. Tan. This 1.7 billion yuan ($ 260 million) network base will “enhance our country’s competitiveness and allow us to gain an edge in the international cyber competition,” said Mr. Tan. more. China has now embarked on building the world’s largest 5G network, and in the foreseeable future, a large number of smart devices – including self-driving cars – will connect to the Internet. These devices can produce and request huge amounts of data, while allowing only minimal communication delay and each device needs a unique ID. According to Mr. Tan, the current Internet base, based on military technology from the 1980s, is not strong enough to meet future requirements. And the more things connected to the Internet, the greater the damage caused by a network attack. New security protocols developed by Chinese researchers to locate and identify any device in the future network will be tested in the CENI network; according to Mr. Tan. The CENI network “will support attack and defense training” by allowing more than 4,000 teams across the country to conduct separate experiments at the same time; he said. Of course, China’s network will not be isolated, but will connect to existing Internet networks, as well as test networks in other countries, including the Future Internet Research and Test Network (FIRE) of Europe; according to the EU.
