UFO films released by Pentagon?

Pentagon declassified some records regarding UFO.

BBC: Pentagon releases UFO videos for the record

According to the media, there are three videos in which unidentifiable flying objects were seen released by the US Department of Defense. But they were already leaked by someone before.

Some people claim that the US officially admit the existence of aliens coming to the earth. I hardly understand it, however. The US never admitted UFO, but simply admitted there were some films of unidentified objects.

To be honest, I do not believe intellectual beings live outside the earth. These films may be a product of an unintended noise.

I am not sure why the US government released such a silly source recently. We are in a serious situation of the battle with corona virus. It is some kind of conspiracy theory to connect these two issues directly. On the other hand,  some people are concerned about UFO, or other occult issues, when fully anxious, of course of COVID-19. I am afraid that similar doubtful theories will emerge one by one soon.

Zoom's value is rocketing

Zoom video communications, a famous telecommunication company is rapidly increasing its market value.

Its stock price is now 165 USD, and its market value has reached 30 billion USD, by four fold higher in this half year.

Money Control: Zoom is now worth more than American Airlines, Expedia and Hilton combined

It is obviously because we have to stay home at the COVID-19 pandemic. Now people utilize video conference systems most vitally than ever before.

Zoom was criticized on its vulnerability to wiretapping. Nonetheless, its usability is admired by many people. The fact that even in the current tragic situation some companies are growing encourages us.

Home cooking due to pandemic

It is often heard that the opportunity of home cooking has been increased since the novel corona virus pandemic made us stay home. Actually, I myself take almost every meal at home now, while approximately half of them were taken outside previously.

Home cooking can be healthier than dinner in a restaurant, some researchers say.

The Conversation: Home cooking means healthier eating – there’s an opportunity to change food habits for good

In my opinion, the main advantage of home cooking is the fact that you can take much vegetable at home. Most restaurants as well as fast-food franchises offer meals with too little vegetable. Also, the meal they provide contains much fat, red meat, and dairy products. They are suspected to harm our body in a longitudinal way.

It is useful to choose some products believed as good for your health in this opportunity. Nuts, red vegetables, some fruits, olive oil are likely to be beneficial.

On the other hand, cooking at home is a serious work for non-skilled people. Relying on preserved food too much for daily meal is no more healthy. Balanced diet is essential for us to maintain our health, especially in this crisis.

Google Card coming?

Google seems to develop its own branded debit card.

TechCrunch: Leaked pics reveal Google smart debit card to rival Apple’s

Tech Crunch leaked some images of Google Card which is similar to Apple's one. If it is true, Google will expand its field of products from information technology to finance. It is not surprising because an independent payment system is crucial for an IT company with a certain size to grow up their business.

Therefore, this event will be a usual activity of Google. I do not believe Google card itself will change our daily life at all.

Dutch court accept mercy killing for demented person

Dutch supreme court accepted mercy killing for demented parsons.

Reuters: Dutch Supreme Court expands euthanasia laws for dementia patients

In this case, the doctor carried out euthanasia on a person who had severe dementia. The person is supposed to have committed a living will of welcoming mercy killing when seriously demented. However, the prosecutor accused the doctor on murder.

The court declared that a doctor can carry out an written request for euthanasia even if he is now not able to express his own will.

This verdict seems rational. If a living will is no more validated when you get demented, people can no longer decide their life after losing their competence.

I believe not a few people do not want to survive their life without their definite will. On the other hand, it is acceptable that a person want to live longer as much as possible even if depending on others. It is an issue of philosophy of life.

Therefore, leaving a living will with a entirely legal way is very important. It is horrible that a doctor who carried out euthanasia with adhering to the patient and his family's will is accused on a murder.

Amazon faces strike because of corona virus

Amazon will face a massive strike of the employees.

According to the media, the motivation of the employees planning the strike is their unsafe condition. They insist there is considerable risk of being infected by the novel corona virus.

Techxplore: Amazon workers to strike over 'unsafe' conditions amid virus

So far, Amazon was criticized for its serious working condition. Amazon.co.uk abandoned fast delivery to keep employees working after broadcasting its gigantic storage in which many workers are engaged to busy and delicate picking. Also in Japan, Sagawa, a famous delivery company, withdrew the contract with Amazon because it could no longer commit Amazon's strict demanding. After that, Amazon prepared direct deliverers on its own.

As a consumer, Amazon provides very helpful services. My life depends on Amazon a lot. But, if its quality of service sacrifices employees' health, it cannot be acceptable.

Facebook bans pseudoscience from advertisement

Facebook removed pseudoscience as a category for advertizement.

Reuters: Facebook gets rid of 'pseudoscience' ad-targeting category

This solution was a reaction to recent situation that many incorrect information about prevention from COVID-19 emerged as the WHO declared "infordemic." Similar to events occurred previously, we are often confused among massive information in a life-threatening situation. Meanwhile, not a few evil people are willing to trick citizens with introducing wrong, or even harmful solutions.

In this sense, Facebook's decision is rational and admirable. But, I am doubtful that it will contribute to get rid of incorrect information from the internet. Most providers of pseudoscience are not aware of the fact that they do not adhere to the principle of science. Objective judgment of the validity for each information is necessary to clean up the internet. Of course, however, it is extremely difficult to distinguish true things from others.

Google and other companies are eager to check the factfulness of each website. Some AI algorithms have been developed to judge them automatically. But their sensitivity and specificity are not satisfactory.

For a while, or decades, we have to be keen to develop our eye to find the truth on our own.

White roof is better for the environment?

White roof is environment friendly, according to some scientists.

Inverse: THE SCIENTIFIC REASON WHY A WHITE ROOF IS BETTER FOR THE ENVIRONMENT

The reason is that white is reflecting color. Some studies suggest that cities composed of many white-roofed houses are less likely to be hit by the heat island phenomenon.

This result is a little surprising. But we often experience that wearing a black jacket makes us feeling warm. It is for the heat keeping effect of black color, not only for the clothes itself. Considering that, a white city may be cool.

In real, some city governments regulate the color of roof and wall of the houses mainly to maintain the harmonious landscape. In Japan, there are few cities with such legislation. But at some areas in Kyoto, some colors destroying the atmosphere of the town are prohibited. Convenience stores in such regions decorate their wall with specific color, different from usual ones of the franchise.

In the near future, white color painting will be mandated for new housing, perhaps for mitigating global warming.

Foolish Rakuten to sell examination kit of COVID-19

Rakuten. Inc. has begun to sell handy examination kit of COVID-19 very recently.

According to the media, this kit is not a medical device. You have to scratch your mucous membrane with a cotton swab, to send it to the examination center. Then you will receive the result.

Nonsense!

Medical examination is not a definite way to determine a person's status. I guess most people believe this kind of test kit will give the answer with 100% of confidence. But, any tests have a risk of false positive as well as false negative. Even in an excellent test kit, sensitivity is up to 90%, and specificity is up to 99.9%. Furthermore, scratching the nose mucous is not an easy way. In my experience of a physician, we often fail to collect the sample, in the flu case.

I am extremely afraid if unskilled people will take this kit to check their status. If thousands of people take the test on their own regardless of the symptoms, there will be massive subjects with false positive or false negative. People of false positive will go to hospital in vein, leading to burdening medical staffs. People of false negative will go out recklessly to transfer the virus.

Rakuten's product is perhaps an excellent one. But, delivering this device to non-expert people is the worst act in the world. We should drop it immediately.

Behavior modification as a solution for COVID-19

In recent, we often hear the term "behavior modification" in the context of COVID-19. Shinzo Abe, The Prime Minister of Japan mentioned this words repeatedly in the declaration of emergency.

Behavior modification is originally a technical term of behavioral science. Our behavioral trait is formed by several factors such as biological characteristics, personality, environment in nurture, and experiences. These traits are deemed as a personality itself. For instance, reckless people often act a risky behavior.

But this behavioral tendency can be altered with some simple interventions, according to latest research. If we get rewards after a particular act, the act will be done more often. How to increase the rate of beneficial behaviors with eliminating harmful behaviors is crucially wanted answer from behavioral scientists. Thus, behavior modification is a core issue.

After corona shock, we have to keep social distance from neighbors. We should avoid crowded spaces. These acts are perhaps coerced by the government. But in Japan, there is no legislation to restrict citizen's activity directly. Therefore, the government expects citizens to modify their behaviors.

As a psychiatrist, behavior science is one of my specialty. I am glad to see the concept of behavior modification is spread to the society, though never welcoming the disaster of COVID-19.

Agricola Revised Edition released

Agricola is a popular board game whose theme is management of a farm.

It is categorized as a worker placement type game. Each players use some workers to take an action every turn. The actions occupied by others cannot be available. Therefore, you have to predict what kind of actions opponents want to do.

Also, you have to feed your workers every harvest phase. If you add workers with an action, the amount of foods needed is increased. Balancing between storing foods and develop new products is essential to win this game.

Agricola had been the best board games chosen by players all over world for a long time on the site of BoardGameGeek. Many players sought the optimized strategy for maximizing victory points.

You can play Agricola on iPad. This app is well made. I have played it many times. The AI is not so strong, but I sometimes lose the game with a hard luck.

And very recently, Revised Edition of Agricola was released. The revised edition is a newly form of Agricola. The original version included some balance-breaking cards such as "Lover (immediately add one worker)" and "Taster (you can take an action in advance of every turn)." These cards were excluded or arranged  in the revised edition.

Unfortunately, the app of revised edition has some critical flaws. Card drafting rule is not introduced. The 5-players game is not available. Also, there are some serious bugs I found. I am waiting for the update.

IT as a solution for lockdown loneliness?

In the state of lockdown, we are forced to stay home. It causes us several problems not only physically but also mentally.

Sense of loneliness has been proven as a factor of shortening life expectancy. And social isolation is no other than loneliness. Thus, we have to manage our solitude somehow to maintain our health.

Latest neuroscience has clarified the characteristics of loneliness as well as the solution for it. Cognitive therapy is beneficial to modify our sense of solitude. As well, behavioral experiment will be effective to actually decrease desperate feeling.

However, several ways of treatment are unavailable now because of behavioral restriction. We cannot talk each other directly. Gyms are closed even if you want to take physical exercise.

Therefore, robotics and other information technologies have to be utilized properly. So far, online session was deemed as inferior to direct conversation in satisfactory level and degree of mutual understanding. It may be correct. But engineers are enthusiastic to overcome the gap.

The Conversation: The neuroscience of loneliness – and how technology is helping us

In my precision, the current situation will last for months, or even years. We have to adapt this status anyway.

Exercise will prevent liver cancer

Here, another benefit of exercise is suggested.

According to a newly published study, regular exercise will stop the development of liver cancer. It had been estimated that people exercise regularly are unlikely to have liver cancer. But its biological basis was unclear. The latest study used mice which were exposed to carcinogen. The group allowed to take exercise regularly grew less percentage of liver cancer.

Independent: Exercise may directly protect against liver cancer, study suggests

This experiment is interesting. But, a dominant cause of liver cancer Hepatitis viruses. Excessive alcohol consumption also leads to liver cancer. Especially in Japan, several people are suffering from hepatitis due to blood transfusion in the past. Also, obesity rate is not high in Japan. Therefore, even if the outcome of this study is correct, it will not have an impact in Japan, I guess.

Entertainment in lockdown situation

In recent, many people are trapped in the house because of the risk of the novel corona virus infection. This situation affects our life in several ways.

Lack of physical exercise causes us many symptoms. Not only metabolism, but also mental activity can be interrupted.

There are some reports that lockdown is a risk for domestic violence. Too much close relationship in a tough and uncertain situation cause anger and hostility to our mind.

In such a case, relaxation and entertainment are essential for maintain our mental health. Fortunately, many companies are offering components which are available via the internet. For example, DriveThruRPG, a huge portal selling role-playing game tools, sells massive PDF articles for low cost. Marvel Unlimited also provides some historic comics such as Avengers for free in a limited term.

The serious situation will continue for a while. We need entertainment. Do not hesitate to enjoy something now.

Amazon lower the fee for affiliate

Amazon will cut the rate of interest of its affiliate program dramatically.

Folio: Amazon Cuts Affiliate Commission Fees for Certain Product Categories

Amazon, as well as some other e-commerce companies, offers affiliate marketing program. Thus, blogger and website organizers can get some rewards when a customer purchase Amazon's goods after clicking advertisement appeared on his web page. The late of reward was up to 8% of the sales.

But Amazon will lower the rate by 30-80% since next week. This decision will strike many bloggers relying on the income from affiliate programs.

Because of COVID-19 pandemic, many people hesitate to go out to shopping. Amazon's sales must be drastically increased in recent. I guess Amazon would like to improve its balance sheet through cutting the cost for affiliate program.

I am not familiar with the advertisement business. I have no ads on this blog. As far as I remember, Amazon lowered the rate of incentive also in the past. Thus, the reward of affiliate will never be risen.

Amazon itself will become more stable, and conservative, company. It is a rational policy for Amazon to survive the next era, I think.

Trump to suspend funding to the WHO?

The US is threatening the WHO with funding.

Donald Trump, the US president, said to suspend funding to the WHO, very recently. He blamed the WHO on its management for COVID-19.

Wirefax: Trump to suspend funding to the World health organisation

Tedros Adhanom, the director-general of the WHO, asked Trump to continue supporting financially to the WHO, emphasizing the good relationship between the US and the WHO.

The Hill: WHO chief says he has good relationship with Trump despite president's comments

Tedros has been broadly criticized that his comment were biased to the Chinese side. Taiwan, not belonging to the WHO because of the opposition of China, is also conflicting with Tedros. He was blamed on discrimination against Taiwan, as well as WHO's reluctant stance for data sharing of COVID-19 with Taiwan.

Thus, Trump's hostility to the WHO seems relevant to the national conflict between the US and China. Also, the fact the US is the nation worst seriously struck by COVID-19 is irritating him.

I believe, however, Trump will cancel his policy soon. He is altering the comments every day. It is in no ways wise for the US as well as the whole world to be against the WHO. Deriving an apology from Tedros will be advantageous for Trump in the coming Presidential election. It is his intention, I reckon.

Anyway, everyone should be collaborative against the COVID-19 crisis. Not hostility, but the fact and solution, should be shared.

Conflict between US and China badly influence on Huawei as well as COVID-19 situation

We are at war against the novel corona virus. Besides, the US and China have fighting on the field of technology for years.

In recent years, Huawei rose to be a giant in this region. Its products were as good as those by Apple and Samsung, or at least not so much inferior. Also, they were far cheap. Therefore, Huawei was recognized as a great threat of the US.

The US government has been taking several ways to ban Huawei's products from the US and global market. It is an example that installing Google's Android on Huawei's tablet became illegal.

As a result, Huawei lost many profits. But the influence was not limited to Huawei itself. International collaboration between the US and China in the industry was also damaged. Some researchers suggest that the conflict between two nations caused broadened infection of the novel corona virus in the US. According to them, if both governments had been collaborated to share the exact information about COVID-19, the current situation would have been different.

Now, the US seems not to stop the battle against China. I do not support the US policy. As a citizen, there is no good of conflict between influential nations.

Thailand and Malaysia weightlifters are banned from Tokyo Olympic

Some athletes of Thailand and Malaysia are banned from Tokyo Olympic games.

Hindustan Times: IWF: Thailand, Malaysia banned from weightlifting at Tokyo Olympics

The International Weightlifting Federation decided to ban Thai Amateur Weightlifting Association (TAWA) and Malaysian Weightlifting Federation (MWF) from participating. Its decision means the athletes belonging to these organization have no right to compete their skills in the coming Tokyo Olympic.

Tokyo Olympic games was postponed by one year due to the novel corona virus pandemic. Nonetheless, the possibility that they can join in the game is still desperate.

The reason of the decision was doping of the athletes, according to the media. Doping is still a major issue in athletes community. I guess there are many suspected athletes who did not take such a trick actually because the modern doping examination has considerable amount of possibility of false positive. On the other hand, it is not surprising that some persons, as well as organizations, and even nations, would like to dope for better record for the reputation and actual benefits.

As far as there are some incentives for doping, similar cases will not be perished. As a physician, doping should not be permitted for its risk to the body. It is a difficult issue to promote healthy and fair competition.

Sweden's situation and lockdown

Sweden is struck by COVID-19 seriously because of avoiding lockdown, according to the media.

Forbes: After Rejecting A Coronavirus Lockdown, Sweden Sees Rise In Deaths

Sweden was a nation which had not adopted lockdown different from EU countries. Its policy possibly have led to more victims. Indeed, the death rate in Sweden is nearly 8%.

While Sweden's situation is quite sorry, we have to learn something to overcome the crisis. Also, delicate interpretation is needed in this issue before jumping into conclusion. It is also possible that a lockdown will cause social confusion leading to more fatality.

Xerox failed to get HP

Xerox abandoned to buy Hewlett-Packard Company.

Reuters: Xerox abandons $35 billion hostile bid for HP

Xerox is a big printer maker. Xerox is representative of copy machine in Japan. It planned to gain HP with a hostile bid.

HP is also a big printer provider. It produce personal computers as well. Buying HP must be beneficial for Xerox.

However, this deal ended unsuccessful. It is said that novel corona virus  pandemic had influenced to the conflict process.

To be honest, I had not known about this news. The current situation get rid of our usual activity.

Boris returned from the ICU

Boris Johnson, the Prime Minister of the UK, seemed to have been recovered from a critical state.

France 24: UK's Johnson moved out of intensive care, 'in extremely good spirits'

According to the media, he was moved from the ICU to a general ward. A spokesman expressed he was in a good spirits. It is very relieving news.

There are some cases reported, however, of reinfected COVID-19. It is unsure why patients are infected again soon after recovering from COVID-19 in spite of ongoing immune. It could be an issue of the PCR test sensitivity. Anyway, I hope Boris will soon perfectly get recovered.

Is wearing a mask effective against corona virus?

The COVID-19 is still expanding rapidly. Very recently, Japan government declared an emergency at last. Prevention from further spread of the novel corona virus is essential to keep our community functional.

Wearing a mask is generally believed as a precaution from transmitting viruses. In Japan, many people wear a mask in winter. I myself, wear a mask not only for viruses but also for mitigating the symptoms of hay fever in early spring.

But wearing a mask was not so common in Western countries. I seldom saw people with a mask in the UK even in cold days.

Regarding COVID-19, the effectiveness of wearing a mask is still controversial. Previously, many government did not recommended people to wear a mask because of its doubtful effect of preventing transmission. Also, if many people buy surgical masks, people at high risks such as medical practitioners cannot get ones.

However, as being revealed of asymptomatic infected persons, officials had to change the policy. Now, several governments ask citizens to wear a mask when going out.

South China Morning Post: To mask or not to mask: WHO makes U-turn while US, Singapore abandon pandemic advice and tell citizens to start wearing masks

It is not easy to examine the preventing effect of a mask exactly. In my sense, wearing a mask is somehow beneficial.

On the other hand, there are not enough amount of masks to all citizens. Indeed, I never see masks sold at a drug store for these weeks. Some worrying people can monopoly the masks. Otherwise, some distribution can be crippled.

Japan government has decided to deliver a couple of reusable masks to all citizens. I believe this act is admirable, at least among some realistic solutions.

Boris Johnson moved to ICU

Boris Johnson got worse to be moved to intensive care unit.

BBC: Coronavirus: Boris Johnson moved to intensive care as symptoms worsen

Boris Jonson is the Prime Minister of the UK. He was ex-mayor of London, and claimed that the UK should leave from the EU. After the Brexit vote, he did not seat the Prime Minister soon. But Theresa May resigned the Prime Minister due to longitudinal confusion of the Parliament, Boris succeeded her. It was a little surprising for me.

Recently, Boris was infected by the novel corona virus. He was hospitalized to get the best medical treatment. But, his status looks worsening. Boris is 55 year old, not so young. I truly hope his recovery.

On the other hand, it is very important that the leader of a nation is healthy and functioning. In the era of Eastern Japan earthquake and Tsunami disaster in 2011, the Prime Minister Naoto Kan and his ally were engaged to address the difficulty. I do not think they took the best way. But, it was fortunate Naoto completed his work at least for a year.

I am afraid that the nonexistence of Boris will cause further confusion to the UK.

Let's Note QV8 here

I renovated a laptop PC from Microsoft Surface to Panasonic Let's Note recently.

Let's Note is a flagship series of Panasonic products. It is not popular not only globally, but also in Japan, mainly because of its high cost. Let's Note series were adopted as an official model PC in the Tokyo Olympic 2020, postponed to the next year unfortunately.

But, I believe its performance is supreme compared with any other laptops.

Let's Note's advantages are high performed CPU, total weight, many types of interface including VGA and LAN. The latest Let's Note equips a USB type C connector. It can be powered via type C, only in the case the adapter can provide over 65W power.

Let's Note QV8 has limited batteries. In my sense, after using it for three or four hours, the battery is expired. It is a terrible disadvantage.

Above all, this machine is cool but somewhat inconvenient. Cost effectiveness is bad, to be honest. I do not recommend to buy it unless you can take some financial support.

Internet conference rises and falls

As novel corona virus pandemic emerges, many companies have to change their business styles.

Among all, connecting with unidentified people is a great risk of infection. Refraining from using public transportation as well as conference is recommended.

However, most businesspersons need to commune to their company. Also, there are several important meetings at work as well as schooling.

Then, online conference can be a solution to keep important contacts. Fortunately, video chatting is now popular in many developed countries. Also in developing nations, not a few people use a chat with a smartphone.

Zoom is one of the most famous video chat systems. Its traffic rose by 20 times due to the pandemic, according to the media.

However, there are several cases reported recently regarding Zoom accident. For example, some strangers intruded to the chat room, to make a hate speech. These cases are called “Zoom bombing.”

Every internet tool has vulnerabilities. If an unaccustomed user recklessly present their meeting ID and password on a public space, it will be a hint for crackers. However, it is said that Zoom has flawed security management. A skilled cracker could get the password at a certain Zoom meeting with over 10% of possibility, according to some media.

If so, Zoom is responsible for exposing customers to the risk of wiretapping. The New York City government declared to ban Zoom from their school settings.

FastCompany.com: Zoom banned from New York City schools due to privacy and security flaws

Being wiretapped of a secret meeting is a great risk for some situation. While several cases were reported about Zoom bombing, most of all seems to be a silly trick, even never acceptable. Culprits may be frustrated to the current situation. Otherwise, they have waited an opportunity to present their twisted ideology. Internet and social network tend to visualize human’s malice. It is an adverse effect of convenient tools. We are tested with not only the pandemic but also infodemic.

Brain tumor can be erased by Vitamin B3?

A research team found a possibility that niacin (Vitamin B3) would be able to cure brain tumor.

Inverse: A “REMARKABLE” FINDING LINKS A COMMON VITAMIN TO FIGHTING BRAIN CANCER

According to V. Wee Yong, a professor at the University of Calgary's Cumming School of Medicine, niacin has a role of promoting immune systems. The result of studies with mice suggested extended survival time of subjects with glioblastoma.

Glioblastoma is one of the most difficult malignant neoplasms. I hardly believe such a simple component as Vitamin B3 will be a solution, to be honest. I hope their research will be successful.

Maintaining your mental health in chronic stress

Corona virus spreading has turned into a new stage, a pandemic, unfortunately.

It can no more be completely controlled. Therefore, we have to take a defense to maintain the current situation until some innovative solution is developed.

Though different from an emergency, long lasting battle is also exhausting. Especially when we cannot know the period it will be over, we tend to feel more stressful.

It is another issue than COVID-19 that you can deteriorate your health status because of chronic lock down. You have to keep yourself clean and alert as far as possible.

There are some tips below you can do everyday.

The New Daily: The five things you can do for your mental health in coronavirus lockdown

Nature: Seven tips to manage your mental health and well-being during the COVID-19 outbreak

I completely agree with the opinion described in these articles. Regulatory life is very important. Human can bare at acute stress for a short term. But if your circadian rhythm is chronically confused, it will get rid of your vitality sooner or later.

Humor is also essential in a tough situation. Do not blame on persons who make a silly joke. They are trying to endure their sorrow. Listening to music is also an easy and cheerful habit you can enjoy now. Stretching your body is one of best practices in daily life.

The battle against COVID-19 will be continuous. We have to change our mind for an adaptive behavior.

Bitcoin after corona shock

As the world is attacked by COVID-19, cryptocurrency is also in a peril.

The price of Bitcoin fell down by a half before corona virus outbreak. After that, it is recovering gradually. But the prospect is still uncertain.

Bloomberg: While coronavirus rages, bitcoin has made a leap towards the mainstream

Previously, Bitcoin was identified as a safe haven because it was independent from any governments or authorities. However, referring recent situations, the price is following the basal currencies.

In my sense, the idea that cryptocurrencies are invulnerable to financial crises is an illusion. Actually, the price of Bitcoin is determined by marketers absolutely. Any official forces cannot create new coins, different from fiats.

However, there are some factors to influence the price of cryptocurrencies outside from its mining process.

For example, when the energy cost is increased by oil shock, many miner will have to give up their work. It leads to downgraded reputation of Bitcoin.

Also, business confidence affects the price of Bitcoin, in my sense. In the boom, many investors are willing to buy Bitcoins. In a depressive state, they would not. Their feeling is somehow influential to the price itself.

In my opinion, recent breakdown of Bitcoin price was reflected with wide-spread pessimism of the market. I do not believe someone would by Bitcoin for safety now.

Therefore, the price of cryptocurrencies will be fracturing for a while, as COVID-19 pandemic will not be terminated soon.

Gloomy April Fool

Today, I write this entry on 1st, April.

Every year, I wrote some silly joke as an idea of April Fool. But this year, I would not like to write something.

The biggest reason is COVID-19 pandemic. More and more patients emerge everyday. We cannot see the termination of growing infectious storm. This situation is quite painful.

In addition, there are some false information, such as conspiracy theories, spread to the society following the tough situation. We have to be calm, neutral, and scientific. We have to avoid the risk of believing false facts.

Furthermore, my business as a researcher is unsuccessful. Therefore, I feel a little pessimistic.

More or less, everyone are inflicted damage by this situation. We have to maintain our daily life with least sacrifice.

Huawei release flagship smartphone without Android

Huawei's newest smartphone will not equip Android, according to the media.

The Jakartapost.com: Huawei flagship phone goes Google-free

Huawei, as well as other Chinese companies, has been sanctioned by the US. Since suspecting some spywares are installed in Chinese products, the US government prohibited Google and other companies to make an alliance with Chinese companies. Therefore, Huawei cannot produce smartphones powered by Google Android. Instead, it developed an original OS for smartphone.

I personally like Huawei's product because it is the only provider releasing 8 inch tablets with an LTE module. I wonder why other companies try to release similar tablets. The withdrawal of Huawei from Android did damage to me a lot.
