MacBook early 2016 has come

I am loving my MacBook. But there are several troubles in handling it. I have much to learn to control my pink gadget.

Referendum for Brexit will come soon

Now, Brexit is one of the biggest issues for world economy. The media suggest the risk of Brexit and several investors are preparing for it. They are moving GBP saving to other currencies.

I myself believe the UK will not choose leaving the policy of leaving the EU unless there are some extraordinary events. On the other hand, it is possible that terrorists make a provocation at this time to interrupt the international coalition.

North Korea declared not to use nuclear weapons unless attacked

Very recently, South Korean government stated that it sensed a preparative movement of an intercontinental missile in North Korea. Japan government ordered Self Defense Force to destroy it in the sky. The situation is very tense.

Pixabay, a media storage of public domain

Unfortunately, my attempts resulted in failure. All of my photos uploaded to Pixabay were rejected, and I lost the right to apply photos any more. The standard was too high for me to pass. Now, I am a consumer of Pixabay, not a contributor.

Frequent ejaculation prevents prostate cancer?

Prostate cancer is one of the main malignant tumors which harass aged men. In the US, one tenth of men is said to suffer from this disease. Asian people are less likely to get prostate cancer compared to black and white. But, the prevalence rate of patients is rapidly increasing recently in Japan, perhaps due to Westernized diet style. Fortunately, prostate cancer is relatively easy to treat. It progresses so slowly that some people need no intervention to prevent premature death.

Some risk factors of onset of prostate cancer are identified. Excessive milk drinking is considered to be a risk. Calcium is also likely to make prostate cancer. Then, how is the relationship between prostate cancer and behaviors relevant to the role of the prostate? Recently, researchers investigated the influence of ejaculation on the onset of prostate cancer.

The result was clear. The more frequently you have an ejaculation, the more certainly your prostate is free from cancer. A cohort study subjected more than 30,000 men for 20 years revealed an inverse correlation between them.

Pubmed: Ejaculation Frequency and Risk of Prostate Cancer: Updated Results with an Additional Decade of Follow-up.

However, you should be cautious about interpreting this result. According to this study, you have to ejaculate 21 times in a month in the 50s to reduce the risk of prostate cancer by 20 %. If I accomplish the frequency, I will get some other disease because of exhaustion.

Of course, this study shares a weakness as well as other cohort studies. Some confounding factors are possible. Men with a low frequency of ejaculation are likely to have some problems in their health, which are potential risks for prostate cancer. Recognizing it, the authors excluded the subjects who have an extremely low frequency of ejaculation. However, it is uncertain how many times of ejaculation is the standard for an aged man. It is still not sure artificially increased the frequency of ejaculation will protect you from prostate cancer.

Avoiding milk sometimes is preferable as prevention, I think.

Obama visit Hiroshima for the first time

Balack Obama, the President of the US, visited Japan for attending G7 summit. It was held at Shima Kanko Hotel, a famous facility in Mie prefecture. After the congress, he went to Hiroshima.

Hiroshima was one of the two cities in the world where an atomic bomb was thrown. Obama looked through Hiroshima city and Atomic Bomb Museum. After that, he made a statement in front of audience including victims of atomic bomb disease, so-called “Hibakusha.” He shook hands with hibakushas and devote flowers to the memorial stone of victims.

The Guardian: Barack Obama says memory of Hiroshima 'must never fade'

In his speech, Obama express a deep sympathy to the victims and emphasize the misery of causing a war. He did not make an apology for dropping atomic bombs on Japan. Instead, he said we have a certain responsibility to abandon the threatening power of nuclear weapons.

USA Today: Sympathy for victims but no apology as Obama makes historic Hiroshima visit

Obama’s speech seems to have an impact to both Japanese and American people. I think his statement is very sincere and humane. It is not easy to determine whether Obama should make an apology about having victimized Hiroshima (and Nagasali) of not. In my opinion, he is not responsible for the act the US conducted over 60 years ago, and it is not certain the use of atomic bomb is justified based on the standard at that time. And if he made an apology, it would not be beneficial for Japan and the US, rather it is possible that it could make the Obama’s successor aggressive.

Anyway, this visit is a historic event. I believe Obama has done a great work. His speech will be unforgettable for a long time.

Hottest summer will come

Recently, it is getting hot in Japan. We have adopted a policy of casual wearing at work, so-called "cool-biz." Nonetheless, the hot and moist weather is annoying.

It is terrible that the weather forecasters predict the hottest summer in this year globally. El Niño oceanic phenomenon will be a cause of heat in summer. In addition, human behaviors make the temperature raised gradually.

The Telegraph: 2016 set to be the hottest year on record, Met Office say

In India, heat wave did damage to the roads. Asphalt is basically invulnerable to shock. It can usually melt in 140 centigrade. However, some compounds in asphalt road are easier to be damaged.

Independent: India’s roads melt as record-breaking heat wave continues

This year, as well as the last one, climate change and global warming are often discussed. These themes had been not so familiar to us because we seldom feel these issues as real. However, in recent years, the abnormal weather is not so rare. Therefore, we have to be aware of the environment around us.

My past entry: March in the highest temperature

My past entry: Climate change and rising of sea level

Also Last year, we were struck by dreadful heat in Japan. Fortunately, I avoided the hottest months with being in the UK.

It is considered that the main cause of global warming is excessive use of fossil fuels. If all fossil fuels burn, the earth surface temperature would be ten centigrade higher.

The Guardian: World could warm by massive 10C if all fossil fuels are burned

I think global warming itself is not fatal for humanity. But, many people will be victimized in the process of rapid climate change. It is essential to minimize the risk of environmental alteration. Therefore, becoming independent from fossil fuel is important for sustainable development of our civilization.

MacBook early 2016 has come

I got MacBook (early 2016 model) for business use.

Macbook was developed last year as the first model of Mac mobile notebook with a Retina display. MacBook Air is an excellent one but equips a display with lower resolution. Therefore, I was looking forward a new model.

However, MacBook in 2015 was expensive referring to its spec. The shape of it did not attract me. So, I dare not to buy it.

My past entry: Too thin new Mac Book with Retina Display

This time, the new model of MacBook was released. It has improved CPU and battery. It is regrettable that only one USB type-C port is available as same as the old model. But it is not so problematic for me because I seldom use a USB memory stick. I usually rely on cloud drives to transfer the data.

My past entry: New Macbook 2016

I decided to buy MacBook for the purpose of my work. To be honest, I was annoyed to use Windows PC every time. It is not sure Mac is superior to Windows. But, it should be a beautiful experience to try a new OS.

How do I feel about the new machine?

I have not examined its performance. But it will be OK for my general use. Despite my concern, it seems tough enough for mobile use. Instead, it is heavy than I expected.

Now I am concerned about its battery. I will be satisfied if it lasts all a day.

London is the second best tech city

London was ranked as the second best city in the world regarding attractiveness to investors, following San Francisco.

EY UN’ Attractiveness Survey 2016 suggested that 21 per cent of investors voted to London, followed by New York and Beijing. Furthermore, 57 % of voters chose London as a favorite place for foreign direct investment. The UK created over 42,000 jobs, the most in any year since 1997.

ITProPortal: London is almost the tech capital of the world


This news is welcomed to Londoners. However, the report also suggested several worries about the future. Only 23 % of respondents thinks positively about consistent investment in the UK for the future. This proportion was decreasing by 4 percent from the previous year. And 36 % believe that UK’s attractiveness will improve, decreased by 18 % from the previous years. These results mean that expectation for the UK about its attractiveness as a subject for investment is questionable.

Attractiveness Survey 2016

As a temporal Londoner, I think London is an attractive city. But, aged infrastructure is one of the biggest challenges for further development. Though lacking personal experience, I think newly developed cities are more convenient both for daily living and business performance. On the other hand, diversity in citizens is considered to be an advantage for the UK. The new mayor of London is a Muslim, for the first time as a governor of a major city in the EU.

As described in this article, the result of Brexit referendum will influence on London and the UK in terms of its value for the investment. If they decide to leave EU, many investors will abandon London, I guess.

Erasable tattoo will come

Ephemeral, a startup company, is eager to develop removable tattoo products.

Tattooing is a method to print something in the live human skin. Nowadays, some people would like to carve tattoos as a fashion. However, the tattoo is hard to be removed. It means that you will deeply regret if you make an unwise choice.

The new technology mentioned above is composed of two solutions. The first is tattoo which will disappear after a year. The second is a way to erase carved tattoos.

Technology Fox News: End of permanent tattoos? Startup develops new high-tech ink

These new techniques can change our mind on the tattoo. Previously, the tattoo was a symbol of anarchism. In Japan, members of traditional yakuza (Japanese mafia) were fond of getting carved a big tattoo on their back and arms. Their figure often scared us, for instance in a public bath. Therefore, most public facilities such as spa, pool, and massage services prohibit people with tattoos from use them. A few years ago, Osaka prefectural government made a commitment not to adopt candidates with tattoos as an official. Hence, many Japanese people are allergic to tattoos.

The second solution releases people who would like to cancel the history in which they get tattoos recklessly.

On the other hand, the temporal tattoo is interesting. I think many tattoo-lovers do not accept it, because they believe they will continue to get along with their tattoos eternally.

The temporal tattoo will be utilized to some other purposes. For example, it can be identification. In the hospital, patients get a name band not to be misidentified to other patients. But this band is a little annoying. If tattoo can be printed to the body temporally without pain, it will replace an ID tag.

Some companies will adopt temporal tattooing as a uniform. In the Olympic or other big games, some supporters will carve a tattoo in their arm to show they are true supporters. Such casual usage is possible to be realized, if the temporal tattoo is provided with low cost and risk.

By the way, I do not like tattoo personally, either tattoo seal. I never exclude people with a tattoo. But, I will not try it even if it is removable.
