Google says it will shut search engine in Australia if forced to pay for news

SYDNEY – Google said on Friday it will disable its search function in Australia if the government proceeds with a media code that would force it and Facebook Inc to pay local media companies for sharing their content. Australia is on course to pass laws that would make the Big Tech giants negotiate payments with local publishers and broadcasters for content.

If they can’t strike a deal, a government-appointed arbitrator will decide the price. The code’s arbitration model with bias criteria presents unmanageable financial and operational risk for Google,” Mel Silva, managing director for Australia and New Zealand, told a senate committee. “If this version of the code were to become law, it would give us no real choice but to stop making Google Search available in Australia Google’s comments drew sharp rebuke from Australian Prime Minister Scott Morrison who said the country makes its rules for “things you can do in Australia.” “People who want to work with that in Australia, you’re very welcome. But we don’t respond to threats,” Morrison told reporters. The United States government this week asked Australia to scrap the proposed laws, which have broad political support, and suggested Australia should pursue a voluntary code instead. Australia announced the legislation last month after an investigation found Alphabet Inc-owned Google and social media giant Facebook held too much market power in the media industry, a situation it said posed a potential threat to a well-functioning democracy. Google’s threat to limit its services in Australia came just hours after the internet giant reached a content-payment deal with some French news publishers. Google’s testimony “is part of a pattern of threatening behaviour that is chilling for anyone who values our democracy,” said Peter Lewis, director of the Australia Institute’s Centre for Responsible Technology.

Astrosat satellite spots ‘dinosaurs of the universe’ globular star cluster:

(The team of scientists found about 34 UV-bright stars were found to be members of the globular cluster.)

Astronomers, with the help of India’s first multi-wavelength space satellite Astrosat, have spotted a massive intriguing globular cluster in the Milky Way galaxy with rare hot UV-bright stars in it, the Department of Science and Technology said on Thursday. These stars whose inner core is almost exposed, making them very hot, exist in the late stages of evolution of a Sun-like star.

It is not clear how these stars end their lives as not many of them are detected in these fast-evolving phases, making their study crucial. The old globular clusters referred to as dinosaurs of the universe, present excellent laboratories where astronomers can understand how stars evolve through various phases between their birth and death with spectacular ultraviolet images of the cluster from Ultraviolet Imaging Telescope (UVIT) on board. Astrosat satellite spots dinosaurs of the universe globular star cluster: Dept of Sci-technical The old globular clusters present excellent laboratories where astronomers can understand how stars evolve through various phases between their birth and death.

Image credit: Wikipedia/Richard Hook, ESO With AstroSat, astronomers from the Indian Institute of Astrophysics, an institute of the Department of Science and Technology, distinguished the hot UV-bright stars from the relatively cooler red giant and main-sequence stars which appear dim in these images.

The findings of this study have been accepted for publication in ‘The Astrophysical Journal’. The team of scientists comprising Deepthi S Prabhu, Annapurni Subramaniam and Snehalata Sahu from IIA combined the UVIT data with observations made using other space missions such as the Hubble space telescope and the Gaia telescope along with ground-based optical observations were also used. About 34 UV-bright stars were found to be members of the globular cluster.

From the data, the team derived the properties of these stars such as their surface temperatures, luminosities and radii. “One of the UV-bright stars was found to be about 3,000 times brighter than the Sun with a surface temperature of about 1,00,000 kelvin,” Subramaniam said.

Buying Bitcoin is the most crowded trade; reminiscent of the 2018 crash

Experts are warning of a bubble building up in Bitcoins, especially considering the sudden spike in volatility and increasing institutional participation The latest global fund manager survey published by BofA Securities showed that buying Bitcoin is being viewed as the most “crowded trade”.

After Bitcoin’s massive rally in recent months, it is hardly surprising that this cryptocurrency is fast regaining its lost glory. From a low of $4,000 in mid-March last year, the price of the world’s first and most famous cryptocurrency has risen by nearly 900%.

Currently, Bitcoin is trading at $34,750. Long Bitcoin jumps to top with 36% of fund manager survey investors saying it is the most “crowded trade” dethroning “Long tech” for the first time since October 2019,” said the survey report. “Investors who have been tracking Bitcoins in the past would recollect that a similar rally in 2017 was followed by a crash. In 2017, Bitcoin rallied from the low of around $790 to a peak of $1,9041 in December. Interestingly, in the December 2017 BofA survey, Bitcoin topped the list of most crowded trades.

In 2018, it crashed by 74%. Even now, many experts have been warning of a bubble building up in Bitcoins, especially considering the sudden spike in volatility and increasing institutional participation. “Most cryptocurrencies are notoriously volatile, and the increase in institutional participation may be making things worse.

While demand would increase and volatility ease should corporations hold Bitcoin for business purposes, the opposite is true when institutions gain exposure for speculative purposes. Empirical evidence from other asset classes suggests that higher participation by institutional investors could increase volatility due to their more opportunistic investment approach,” Michael Bolliger, chief investment officer, global emerging markets, UBS Switzerland AG said in a report on 14 January.

Ultimately time will tell what holds true for Bitcoin investors but those in the bullish camp see further upside. For instance, according to JPMorgan Chase & Co, Bitcoin has the potential to reach $146,000 in the long term as it competes with gold as an asset class. Posted by Technical Mechzone

Bitcoin (BTC/USD) Forecast

Bitcoin sell-off a threat to major cryptocurrencie Bitcoin prices have rebounded slightly, following a sell-off from Friday’s high, where BTC/USD broke above $40,000, before facing a wall of resistance formed by the key psychological level of $42,000.

The three day sell-off resulted in a $10,000 depreciation in the digital currency, raising concern that the Bitcoin ‘bubble’ had officially burst. However, the pullback in prices is no comparison to the massive 949% surge from March 2020 low. Bitcoin TradingBitcoin Trading Meanwhile, fundamental factors appear to be influencing price action, with Bitcoin recently portraying the same characteristics as Gold, Silver and other safe-haven assets, which benefit from US Dollar weakness. On the regulatory front, additional drivers of price action have been attributed to warnings from both the New Zealand and UK regulators (FMA & FCA respectively) who have cautioned individuals against trading Bitcoin and other digital currencies.

BITCOIN (BTC/USD) TECHNICAL ANALYSIS After plunging approximately 11% in yesterday’s trading session, Bitcoin bulls were able to bounce off trendline support, pushing price action to a zone of resistance, formed by the 23.6% Fibonacci retracement (between November 2020 low and January 2021 high) at $35,866. The 20-period Moving Average (MA) continues to provide additional support, while the Relative Strength Index (RSI) now rests beneath 70, indicating that BTC/USD may be exiting overbought territory. Building Confidence in TradingBuilding Confidence in Trading What does it take to be a confident trader? . Get My Guide Bitcoin (BTC/USD) Daily Chart If bulls are able to break above current resistance, a bullish continuation could be probable, with the potential retest of $40,000. However, if bears are able to drive prices lower, a break below current support, could bring the 50% Fibonacci retracement into focus at $29,023 BITCOIN (BTC/USD) SENTIMENT Bitcoin (BTC/USD) Bulls Bite the Bullet How to Use IG Client Sentiment in Your TradingHow to Use IG Client Sentiment in Your Trading RECOMMENDED BY Technical Mechzone How to read client sentiment Get My Guide At the time of writing, retail trader data shows 84.05% of traders are net-long with the ratio of traders long to short at 5.27 to 1.

The number of traders net-long is 7.02% higher than yesterday and 16.14% higher from last week, while the number of traders net-short is 15.08% lower than yesterday and 20.86% lower from last week. We typically take a contrarian view to crowd sentiment, and the fact traders are net-long suggests Bitcoin prices may continue to fall. Traders are further net-long than yesterday and last week, and the combination of current sentiment and recent changes gives us a stronger Bitcoin-bearish contrarian trading bias.

Whatsapp की नई तरकीब, Status लगाकर समझा रहा प्राइवेसी नियम!!!!!!!

इंस्टैंट मैसेजिंग एप व्हॉट्सएप को प्राइवेसी पॉलिसी (Whatsapp Privacy Policy) में बदलाव को लेकर आलोचना का सामना करना पड़ रहा है। दुनियाभर में इस बात को लेकर चिंता जताई जा रही है कि व्हॉट्सएप यूजर्स के डेटा को फेसबुक से साझा कर सकती है।

ऐसे में व्हाट्सएप लगातार यूजर्स को यह समझाने में जुटी है कि नई पॉलिसी से यूजर्स के प्राइवेट डेटा को किसी प्रकार का खतरा नहीं है। कंपनी ने पहले सोशल मीडिया प्लेटफॉर्म्स और फिर न्यूजपेपर्स में बड़ा विज्ञापन देकर अपनी बात रखी। अब कंपनी ने यूजर्स को प्राइवेसी नियम समझाने के लिए नया तरीका अपनाया है।

Whatsapp ने पहली बार लगाया स्टेटस? दरअसल व्हाट्सएप अपने Status फीचर के जरिए यूजर्स तक पहुंच रही है और प्राइवेसी नियमों को समझाने की कोशिश कर रही है। यह शायद पहली बार होगा जब व्हाट्सएप ने खुद कोई स्टेटस लगाया है। हालांकि अन्य स्टेट्स की तरह इनमें रिप्लाई का ऑप्शन नहीं दिया गया है। व्हाट्सएप ने कुल 4 स्लाइड की स्टोरी पोस्ट की है, जिसमें कहा गया है कि कंपनी यूजर्स के कॉन्टैक्ट या लोकेशन को फेसबुक के साथ शेयर नहीं करती और ना ही उनकी बातों को पढ़ या सुन सकती है।

व्हाट्सएप स्टोरी की पहली स्लाइड में लिखा है, ‘हम आपकी प्राइवेसी को लेकर प्रतिबद्ध हैं।’ दूसरी स्लाइड में लिखा है, ‘व्हाट्सएप आपकी पर्सनल बातचीत पढ़ या सुन नहीं सकता, क्योंकि ये एंड टू एंड एनक्रिप्टेड हैं।’ वहीं, तीसरी स्लाइड में कहा गया है, ‘व्हाट्सएप आपकी शेयर की गई लोकेशन नहीं देख सकता।’ और आखिरी स्लाइड में दावा किया गया है कि, ‘व्हाट्सएप आपके कॉन्टैक्ट्स फेसबुक के साथ शेयर नहीं करता।’ नई पॉलिसी लाने की तारीख बढ़ी उधर व्हाट्सएप ने पॉलिसी में बदलाव (अपडेट) को 15 मई तक के लिए टाल दिया है। व्हॉट्सएप ने ब्लॉग पोस्ट में लिखा है कि यूजर्स के लिए पॉलिसी अपडेट की शर्तों पर अपनी मंजूरी देने की तारीख को आगे बढ़ाया जा रहा है।

इससे पहले व्हाट्सएप ने 8 फरवरी 2021 को पॉलिसी मंजूर करने की आखिरी तारीख तय किया था। व्हॉट्सएप ने कहा, ‘हमारे हालिया अपडेट को लेकर काफी असमंजस है। काफी गलत सूचनाएं फैल रही है, जो चिंता की बात है।’ नई पॉलिसी के फैसले के बाद से ही बड़ी संख्या में यूजर्स टेलीग्राम और सिग्नल जैसे ऐप्स पर अकाउंट बना रहे हैं। Posted by Technical Mechzone

After dizzying gyrations, what’s bitcoin really worth?

The virtual currency barrelled to new highs to rise more than 400% over the past year, before promptly sliding some 20% and then settling around $36,000 After the latest wild ride took the poster child of cryptocurrencies above $40,000 before a stomach-churning plunge, the million dollar question won’t go away: how much is bitcoin actually worth? The virtual currency barrelled to new highs to rise more than 400 percent over the past year, before promptly sliding some 20 percent and then settling around $36,000. When it started life in 2009 as open-source software, bitcoin was essentially worth zero — though within a year it had reached the heady heights of eight cents. At today’s market rates, bloated by a surge in institutional demand, the digital unit’s market capitalisation is worth some $670 billion with myriad other crypto coins such as ethereum lifting the sector nominally close to the trillion mark. Although that’s small potatoes compared to the $68 trillion or so swilling around world stock markets, it is nonetheless the sort of financial territory staked out by Wall Street tech royalty such as Google, Apple or Tesla. One tech site, AssetDash.com, notes that bitcoin is currently worth around as much as Facebook and a little more than Chinese e-retail giant Alibaba Although deep-pocketed investors have recently become enthusiasts, crypto was in its early days the preserve of geeky amateur investors. It is the latter who have mainly suffered as an estimated four million of the roughly 19 million bitcoin units currently in circulation have been lost. “Lost” does not mean the coins have fallen down the back of the sofa or through a hole in a trouser pocket: they have been electronically zapped from the record, often because their owner has forgotten a password to coins hoarded on a USB stick. One US developer mislaid his password after storing 7,002 bitcoins on one such flash drive, forcing him to wave goodbye, on paper (or rather, the trading screen), to around $280 million. This week, Welshman James Howells desperately offered his local authority a quarter of his fortune to dig up a landfill site where he believes a hard drive he accidentally tossed away — and which has since soared in value to around $270 million — is buried.

The council refused, citing the cost and logistical restrictions. According to analysts at JP Morgan, bitcoin may be highly volatile but could go as high as $146,000 per unit, putting it in competition with gold as an asset class in terms of private sector investment. That volatility, as well as the unregulated and decentralised nature of the bitcoin beast, are key reasons why many seasoned financial observers are scared off — as well as the risk of “losing” their stash. “Most of the lost bitcoins were acquired in the early days,” said Philip Gradwell, economist with Chainalysis. Gradwell said that around one in five bitcoins in circulation today have not budged from their location in five years — since days when the unit was worth not much more than $100. “One or two million of those belong to Satoshi himself,” added Gradwell, referring to the creator of the coin, whose identity remains unknown. He added that the bulk of investors are not day-to-day traders, but people making a long-term punt — and he estimates that the spectacular price boom of recent weeks has involved only around five millions units. Patrick Heusser, head of trading at Swiss trader Crypto Broker, said that following the trading volumes of a variety of cryptocurrencies, rather than just bitcoin, would give a better idea of how the market is faring. “Ethereum has a lot of activity on the chain, but on the litecoin side there is almost nothing going on,” said Heusser, with the former valued at some $138 billion currently, and the latter at $10 billion. Heusser suggested the rises have been largely a bitcoin slipstream effect, and he cautioned against drawing parallels with gold. “To be honest I don’t believe that it is a very powerful or insightful metric inside what’s going on in the crypto market,” Heusser concluded. After years of experience on traditional currency markets, he judged that it was early days for the crypto equivalent. Posted by Technical Mechzone

How to manage your contacts on the WhatsApp Share Sheet for iOS WhatsApp offers the support to show your WhatsApp contacts on the iOS share sheet. In this article we explain how to manage these contacts, and how to fix all issues that may occur. WhatsApp allows to show your contacts and groups on the iOS share sheet on iOS 13.6 and newer updates. But is there a way to manage your contacts and groups there? Definitely yes. Add a new contact: You can add a new contact on the share sheet simply sending a message to that specific contact. WhatsApp automatically adds contacts and groups in the share sheet every time there is a new outgoing message in the chat. Note that Screen Lock, in WhatsApp Settings > Account > Screen Lock must be disabled. Remove a contact: If you don’t like to see a specific contact in the share sheet, you have two possibilities, based on which iOS version you’re on: iOS 13: you can remove him blocking and unblocking that contact. WhatsApp automatically removes contacts from the share sheet every time the user is blocked. Note that the contact will be added again every time you chat with him. For groups there isn’t actually a fast way (excluding the possibility to exit from the group). We understand it’s very uncomfortable, but it’s the only way on iOS 13. iOS 14: tap and hold the contact/group on the share sheet and you can remove it. Remove all contacts: You can remove all contacts simply enabling Screen Lock. For privacy reasons, WhatsApp automatically removes all contacts from the share sheet every time you enable Screen Lock. Sometimes the iOS share sheet has issues and WhatsApp contacts doesn’t appear or they do nothing. How to fix? WhatsApp contacts are disappeared: This likely happens after updating your WhatsApp version from the App Store. You have to open WhatsApp and every time you send a new message in a chat, WhatsApp starts to populate the share sheet again. Nothing happens when selecting contacts: The reason is the same above mentioned: just open WhatsApp again after an update and they should start working. If this doesn’t fix the issue, send manually a message to a contact (to update the contact in the share sheet) and try again. If the issue isn’t fixed yet, block and unblock the contact to remove it from the share sheet (because it might be a “bad shortcut”), send a message to that contact and it should work. Some people have also reported that restarting the iPhone definitely helps to fix this bug, because WhatsApp extensions are reloaded. Contacts never appear in the share sheet: As mentioned above, when Screen Lock is enabled, WhatsApp doesn’t add contacts in the share sheet, for privacy reasons. You have to disable Screen Lock if you would like to see them there. Unfortunately you cannot have Screen Lock enabled and contacts in the share sheet at the same time. Posted by Technical MECHZONE

Quantum cryptography network spans 4600 km in China

Quantum lightQuantum light: a 2000::km fibre optic network enables quantum key cryptography between four cities in China.

A network for quantum key distribution (QKD) spanning thousands of kilometres has been built in China. It links four quantum metropolitan area networks (QMANs) in cities in eastern China with a remote location in the far west of the country.

The system comprises a 2000 km fibre optic link between the cities of Shanghai, Hefei, Jinan and Beijing and a satellite link spanning 2600 km between two observatories – one east of Beijing and the other just a few hundred kilometres from China’s border with Kazakhstan.The network was built by Jian-Wei Pan at the University of Science and Technology of China in Hefei along with colleagues in academia and industry.

QKD uses the principles of quantum mechanics to allow two parties to share a secret cryptography key. A crucial feature of QKD is that the two parties can tell if an eavesdropper has intercepted the key while it is being shared. Once the secrecy of the key is established it can be used to exchange encrypted messages using a conventional telecoms network.Quantum states of photonsIn standard QKD implementations, information is encoded in the quantum states of photons – which are exchanged between the two parties. Photons are used because they can travel several hundred kilometres in optical fibres before their quantum information is lost.

Photons can also carry quantum information between ground stations and satellites, allowing QKD to be performed between locations thousands of kilometres apart.The Chinese network serves about 150 users and comprises more than 700 fibre links and two high-speed satellite-to-ground free-space links – all of which support QKD transmission. The fibre links are supported by 32 “trusted relay nodes” that are capable of forwarding quantum information. The individual QMANS contain trusted relay nodes as well as user nodes and optical switches.

The Jinan QMAN is the largest, containing 50 user nodes supporting 95 users.The satellite portion of the network makes use of the Micius quantum communications satellite, which was launched by China in 2016. Just one year later, Micius was used to make a QKD connection between Beijing and Vienna, which are separated by 7400 km. Technical Information , Technology,Inventory,Technical Mechzone

5am, the Beach

As long as I was on the path I walked hard, but when I came to the black beach I had to run. For the tide was now nearly flowed; and to get through with my powder dry between the surf and the steep hill, took all the quickness I possessed. As it was, even, the wash caught me to the knees, and I came near falling on a stone. All this time the hurry I was in, and the free air and smell of the sea, kept my spirits lively; but when I was once in the bush and began to climb the path I took it easier.

The fearsomeness of the wood had been a good bit rubbed off for me by Master Case’s banjo-strings and graven images, yet I thought it was a dreary walk, and guessed, when the disciples went up there, they must be badly scared. The light of the lantern, striking among all these trunks and forked branches and twisted rope-ends of lianas, made the whole place, or all that you could see of it, a kind of a puzzle of turning shadows. They came to meet you, solid and quick like giants, and then span off and vanished; they hove up over your head like clubs, and flew away into the night like birds. The floor of the bush glimmered with dead wood, the way the match-box used to shine after you had struck a lucifer. Big, cold drops fell on me from the branches overhead like sweat. There was no wind to mention; only a little icy breath of a land-breeze that stirred nothing; and the harps were silent.
