Environmental impact of cryptocurrency

Ten years ago, an anonymous cryptographer laid out the principles of an online currency that would operate beyond the reach of governments and central banks. — dpa

BITCOIN was supposed to solve the problems of analogue currencies. Instead, it created a new one: an enormous amount of global energy consumption that rivals the power usage of an entire country like Ireland.

According to findings of a new study, the implementation of this cryptocurrency could lead to enough emissions being produced so that global temperatures rise 2°C by 2033.

The study, which was published in the journal Nature Climate Change, found that the hardware and electricity needs of Bitcoin alone could significantly impact climate change for the worse.

“Currently, the emissions from transportation, housing and food are considered the main contributors to ongoing climate change. This research illustrates that Bitcoin should be added to this list,” said Katie Taladay, one of the paper’s co-authors from the University of Hawaii at Manoa.

The technical design of how transactions are processed causes Bitcoin and many of the growing numbers of rival cryptocurrencies to consume an enormous amount of energy in so-called Bitcoin mining centres around the world.

And yet the digital currency Bitcoin is still enjoying hype as one of the greatest financial phenomenons of our time.

The foundation for Bitcoin was laid out 10 years ago when an anonymous cryptographer using the name “Satoshi Nakamoto” published a paper laying out the principles for autonomous digital money.

The ideas it contained were revolutionary: No control by central banks, no national borders.

Instead, a mechanism called blockchain would provide trust and security in the system. In broad strokes, blockchain is a publicly viewable ledger of transactions, each saved one after the other.

But as the cryptocurrency’s wild fluctuations and electricity needs have attracted a lot of media attention, the ramifications of the latter have only recently been brought to light.

In a different article published in May by financial economist and blockchain specialist Alex de Vries, the electricity consumption of Bitcoin was estimated to be around the same as the electricity use of the Republic of Ireland.

De Vries also predicted that Bitcoin could be using as much as half of a percent of the world’s total electricity consumption by the end of this year.

“To me, half a percent is already quite shocking. It’s an extreme difference compared to the regular financial system, and this increasing electricity demand is definitely not going to help us reach our climate goals,” de Vries said.

“With the ever-growing devastation created by hazardous climate conditions, humanity is coming to terms with the fact that climate change is as real and personal as it can be,” said Camilo Mora, associate professor of geography in the College of Social Sciences at UH Manoa, Hawaii.

“Clearly, any further development of cryptocurrencies should critically aim to reduce electricity demand,” Mora, the lead author of the new study warns.

So as Bitcoin celebrates 10 years since its creation and it gains more and more supporters each year, we should probably take a moment and give this energy-sucking technology a re-think. – dpa By AMY WALKER

China's J-20 Stealth Fighter Stuns by Brandishing Full Load of Missiles at Zhuhai Air Show

In the last day of China's biennial air show and weapons expo in Zhuhai, a pair of the country's J-20 heavy stealth fighters added a surprise twist to their routine—they popped open their weapons bays and showed off full magazines of missiles. This is the first time such a full load of weapons has been fully exposed and the first time China has officially shown off the jet's complete internal weapons configuration in the flesh.

China’s J-20 Stealth Fighter Will Likely Look Like This At Its Air Show DebutBy Tyler Rogoway 

What we see isn't necessarily surprising, but it is interesting nonetheless. In the main ventral bays, the J-20 is carrying four PL-15 medium-to-long-range air-to-air missiles. The type is somewhat analogous to the American AIM-120D AMRAAM. Speculation about what missile actually would hold the PL-15 designation has bounced around a lot, with very long-range missiles and those fitted with throttleable ramjets also potentially receiving the designation, but now it seems the PL-15 is indeed a dual-pulse motor and AESA equipped missile with a similar profile as its predecessor PL-12. The PL-12 is loosely analogous to the AIM-120A/B.

Chinese Internet

Note that even with their clipped fins, only four PL-15s are mounted in the J-20's bays in a similar fashion to the YF-22's missile configuration. It isn't clear exactly what the launch mechanism for these missiles is based on these photos. A staggered arrangement with six PL-15s may be possible in the future by the looks of the bays, but this depends a lot on the how the missiles are ejected from the bay itself. The F-22 uses a trapeze launcher system to chuck the missiles clear of the bay. The J-20's main weapons bays also look remarkably uncluttered, which makes one wonder if the missiles are just mounted to static hardpoints inside, but this is doubtful as what appear to be launchers have been visible in the J-20s bays for years. 

Chinese Internet

The most interesting part of this display of the J-20's lethal payload carrying abilities is the pair of PL-10s deployed on the outside of the jet's side weapons bays. This novel configuration is one of the most fascinating aspects of the J-20's design. I was one of the first to point it out and explain its utility back in early 2013, when I wrote the following:

"The F-22, a very loose analog for the J-20 (emphasize very), uses a canted trapeze that pushes the AIM-9’s seeker out into the air-stream for proper establishment of a lock before launch once the bay doors are swung open. Only once the missile has acquired a target and the pilot 'receives tone' (the AIM-9 series has an audible growl as it hunts for a heat source, once it finds one it goes from an intermittent growling sound to a solid tone, cueing the pilot to fire) the missile can be fired and only then do the launch bay doors close up.

This method increases the F-22’s radar signature dramatically while also disturbing the airflow around the jet which makes for lower performance and a rougher ride during close-in air combat maneuvering, or dogfighting. Soon, the F-22 will have the AIM-9X Block II which features lock-on after launch data-link capability. In other words, the pilot can 'acquire' a target via his or hers onboard sensors, including the hopefully forthcoming Scorpion helmet mounted display... Once the target is 'virtually locked' within the AIM-9X Block II’s engagement envelope the pilot can quickly fire the Sidewinder, with the bay doors opening and closing momentarily, and allow the data-link to transfer the acquiring secondary sensor’s info to the missile after it has left the bay in the form of a vector [to the target]. The missile will fly in this prescribed direction so that it can acquire the target itself, at which point the AIM-9X Block II becomes truly 'fire and forget.'

Once the AIM-9X Block II is integrated into the Raptor, and especially once the helmet mounted display is operational, the F-22’s side bay doors only have to briefly open to let the AIM-9X on its one-way mission. All this begs the question: If China loves copying the US when it comes to weapons systems, why not just build something similar for the J-20 when it comes to deploying its short-range air-to-air missiles?
The answer is quite simple, lock-on after launch capability is not an easy one to achieve. It is technologically complex, requires deep systems integration (software architecture permitting), and robust testing using live missiles, and thus it is expensive. China, being the resourceful and cunning folks that they are, figured out a way to employ any new or relatively archaic high-off-bore-sight short ranged air to air missile while keeping the jet’s aerodynamics relatively intact (doors closed during prolonged maneuvering while the missile hangs out on its rail) while also minimizing the impact a 'deployed missile' has the J-20’s low radar cross-section.

That is right folks, China just said "we don’t want to have to rely on LOAL capability, so why not just temporarily (as in for seconds or minutes) mount a similarly agile, but much less complex and expensive, short ranged air-to-air missile outside of the bay during times when close range combat is imminent?”

This is exactly what they did, and honestly, I think it is genius. Radar signature becomes a small factor when fighting for one’s life at close range, having a reliable missile ready to make a u-turn off the rail and subsequently turn your enemy into chaff is so important that is can be seen as a life and death requirement [especially for a big, not remarkably maneuverable fighter]. The alternative, such as the reality the F-22 has faced for the better part of a decade, is that you open the bay up for prolonged periods of time and pay a large penalty in radar cross section and [some] performance. Also, by building a relatively simple contraption, kind of similar to one of those bars that goes on your lap on a roller coaster, albeit with a missile attached, Chinese engineers simplified the launch system and also probably made it much lighter than an F-22 type design. Once again, genius.

Another point to be taken from the J-20’s short-range air-to-air missile launch mechanism revelations are that designers absolutely thought it was necessary to give this jet high-off-bore-sight close range missile capability from day one, and in a reliable and persistent nature when needed. This could be due to lack of maneuverability and/or because of its mission, which I have said for years is to break through the enemy’s (American, Taiwanese etc.) fighter cover and take out their enablers (see tankers, AEW&C, C2 and connectivity nodes). In such a case, being electronically silent is your best bet at surviving, so using infra-red passively guided missiles, which require no electronic emissions, at medium-close ranges may be your only play, at least for anything that does not put out a continuous or semi-continuous form of radiation (see AWACS or JSTARS). In that case, a passively guided anti-radiation missile may be the J-20’s weapon of choice, or a medium-long range AAM that can get within locking distance and featuring active radar or IR for terminal homing, via a traditional data-link feeding the J-20’s targeting picture to it provided by passive sensors (IRST, ESM etc).

Malaysia's Human Resource Development Fund (HRDF) a 'personal piggy bank of sr managers!

Moving ahead: (From left) HRDF board director J. Rasamy Manikkam, GOC chairman Tan Sri Rebecca Sta Maria, Kulasegaran, HRDF board director Datuk Quah Thain Khan and HRDF chief executive Elanjelian Venugopal at the townhall meeting.

 Petty cash in the millions

Millions were pouring into the HRDF. And for some high-ranking personnel, their exorbitant salaries and bonuses weren’t enough. Greed got the better of them and they treated the fund as their personal bank, helping themselves to some RM100mil, maybe more!!

KUALA LUMPUR: High-ranking staff of the Human Resources Development Fund (HRDF) misappropriated about RM100mil or about a third of the RM300mil in the fund.

While certain management staff members were overpaid with high salaries and bonuses, some training providers and a number of HRDF management personnel misused the fund in the name of training to purchase commercial properties.

Large sums of money were diverted without the authorisation of the HRDF board and there was collusion between managerial staff and external parties to award contracts.

Human Resources Minister M. Kulasegaran revealed these wrongdoings at a townhall meeting with representatives of employer associations and HRDF-registered employers yesterday.

He said that some members of the HRDF board of directors also did not declare their vested interests to the board.

“There have been wrongdoings, such as abuse of duties, criminal breach of trust and exceeding procedure without reporting to the board.

“(They were) running (the HRDF) as though it was their own company,” he said.

Kulasegaran, who initiated a five-member independent Gover-nance Oversight Committee (GOC) to review and probe the allegations, said that there were elements of fraud in the misuse of the fund in the name of training.

The HRDF is an agency under the Human Resources Ministry that manages a fund for human resource training and development that were contributed by employers.

Regarding the alleged misappropriation of the fund, Kulasegaran said that the HRDF board was only informed after the money was spent.

“Out of RM300mil, nearly RM100mil has been spent,” he said, adding that some department officers, in other instances, also exceeded their authority and approved projects beyond their authorised limit.

When asked, Kulasegaran said that some staff allegedly involved in the wrongdoings are still holding positions in the agency, while some had left.

“After the Pakatan Harapan government took over, three directors have since resigned.

“If they have done anything wrong, action will be taken against them. We will let the process take place. It is not fair at this juncture to make allegations,” he said, adding that two police reports have been lodged based on the GOC report.

Not denying that more former and current HRDF staff are expected to be called up for questioning, Kulasegaran said that parties at fault would be pursued through civil and criminal proceedings.

“After this, I hope the HRDF management will make the agency transparent and accountable to the public,” he said.

Meanwhile, a source that has left the HRDF organisation told The Star that in the week before the townhall, three senior figures within the organisation were subject to domestic inquiries and released from the company.

Another three senior members were on contract and when their contracts expired recently they were not renewed.

A key figure implicated in the scandal resigned soon after GE14.

“Some senior figures have survived, but there is a definite clean-up exercise under way,” said the source.

In some cases, those due to leave found themselves locked out of their offices and escorted off the premises by security when they arrived for work.

The sources said finance personnel and those in special projects who released funds without going through the proper channels, and those who invested money without any accountability are believed to be among those implicated.

“A lack of accountability on the 30% given by companies to the HRDF led to certain figures treating it like a personal piggy bank,” said the source.

He said the culprits are now looking at making deals by providing evidence against the leadership in return for an easy way out.”

“The rot runs deep, and the money runs into billions,” he said. “That’s why there was no choice but to stop the 30% policy and fix the system before restarting it.”

The source said that a key figure implicated in the wrongdoings used tactics such as poor appraisals and internal audits to try to force out those who spoke out against dubious practices.

Some of the questionable property transactions may have involved property in Bangsar South, said the source. - The Star by allison lai and martin vengadesan

World's first artificial intelligence (AI) news anchor

The new AI anchors, launched by Xinhua and Beijing-based search engine operator Sogou during the World Internet Conference in Wuzhen, can deliver the news with “the same effect” as human anchors because the machine learning programme is able to synthesise realistic-looking speech, lip movements and facial expressions, according to a Xinhua news report on Wednesday.

Develop and control: Xi urges China to use AI in race for tech future

“AI anchors have officially become members of the Xinhua News Agency reporting team. They will work with other anchors to bring you authoritative, timely and accurate news information in both Chinese and English,” Xinhua said.

The AI anchors are now available throughout Xinhua’s internet and mobile platforms such as its official Chinese and English apps, WeChat public account, and online TV webpage.

https://youtu.be/GAfiATTQufk

The world's first artificial intelligence (AI) news anchor made "his" debut at the ongoing fifth World Internet Conference in east China's Zhejiang Province.

The news anchor, based on the latest AI technology, has a male image with a voice, facial expressions and actions of a real person. "He" learns from live broadcasting videos by himself and can read texts as naturally as a professional news anchor.

The AI news anchor was jointly developed by Xinhua News Agency, the official state-run media outlet of China, and Chinese search engine company Sogou.com.

According to Xinhua, "he" has become a member of its reporting team and can work 24 hours a day on its official website and various social media platforms, reducing news production costs and improving efficiency.

Celebrity anchors are regarded as important assets at major news networks in the US. The highest paid news anchor, CNN’s Anderson Cooper, is reportedly paid US$100 million a year, while Diane Sawyer at ABC and Sean Hannity at Fox News earn US$80 million each. Celebrity anchors in China are generally paid a lot less because they work for state-run TV stations but they often earn extra money from product endorsements and book sales.

Predicting Beijing’s thinking via AI and People’s Daily

But AI anchors may one day challenge the human variety because of their ability to work 24 hours a day provided human editors keep inputting text into the system.

Xinhua said the achievement was a  “breakthrough in the field of global AI synthesis”, pioneering the synthesis of real-time audio and video with AI-created anchors in the news field. Search engine Sogou, which also does research and development in AI, is providing the underlying technology for the project.

China plans to be a world leader in artificial intelligence by 2030

The AI technology has a “endless prospects” because it will greatly improve the efficiency and reduce the cost of producing daily TV news reports, Xinhua said, adding that it could also quickly generate breaking news reports to improve the timeliness and quality of such reports. - South China Morning Post
