Purchase of 4K Display (Dell P2715Q)

I bought Dell 4K Display P2715Q. I’m using with New Macbook (12 inch) and Vaio Z Canvas.

DELL P2715Q

DELL P2715Q

It is difficult to set up. Many problems had happen. It might be because of large bandwidth usage.

Screen flickering with Included cable

This problem had happened when connected with Vaio Z Canvas. The cable connecting was the cable which converts mini DisplayPort into DisplayPort.
Sometimes screen flickering happend, sometimes it became blank screen. Sometimes becomes stable. They happened in any resolution mode.

I noticed that it became stable when putting up the cable little bit. I think connectors or cable around connecter had broken, so I purchased new cable. I bought Cable Matter’s mini DP to mini DP cable from Amazon.
My display became very stable when using this cable. This flickering problem was caused my the included cable.

Some people said the included cable was wrong at some review sites (Reviews for P2715Q at Yodobashi Camera, thread of this display at 2ch and so on.)

Unstable when 4K

This problem was also happend when using with Vaio Z. Sometimes I could not select 4K resolution mode. Or sometimes become unstable when select 4K.

This problem caused by combination of Vaio Z Canvas and Windows 10. I updated my BIOS Firmware at Vaio’s site (BIOS R1090VE Windows 8.1/Windows 10アップグレード用) then this problem had dissapeared.

Few flickering when using with New Macbook 12 and HDMI 4K30p

This problem was rarely happened. This combination was almost stable. But sometimes white screen flickering happened repeatedly (about 30 seconds period).
This was because of 7m long HDMI cable which I used. I had shorter (2m) cable, so I switched cable to it, then this problem had dissapeared.

I bought 4K monitor, but no machine can play 4K60p contents

I cannot see any 4K60p contents smoothly.
I had not any PC’s which could play 4K60p movies. My Vaio Z Canvas could not too. Dissapointed.

No problem with Linux

I’m using this display with Linux on Vaio Z Canvas, no problem happens after installing BIOS update firmware. I could use as 4K 60Hz with Gnome3 normally.

Misc.

I had used 2K Dell monitor. New 4K display is lighter than my old display. My display arm became able to move up and keep. Light thing is good.

Also USB 3.0 Hub functionality is a little bit useful. Good.

Vientiane: Central Bus Station has been Moved (2015/10/14)

BUS-EC

Central Bus Station (CBS) in Vientiane had been moved. CBS has many buses which goes to north Thailand and many places in Laos.
Maybe this is a temporary moving because of construction of new bus station building. New temporary bus station is located about few hundreds meters from original place. So it could go by walk.

List of destinations

There was a sign like this:

Information sign about Bus station (Maybe)

Information sign about Bus station (Maybe)

I cannot read Lao language (Tell me if this is wrong understanding) but maybe this is like this:

Under construction

CBS is under construction. Bus station divided two places. Please go there.

CBS1 (North) has buses depart for:

  1. Laos – Thai International Bus
  2. Bus 29: Dongdok
  3. Bus 23: Thangon
  4. Bus 20: Dongkhamxang)
  5. Bus 32: Donepamai

CBS2 (South) has buses depart for:

  1. Bus 14: Friend ship bridge (* and also goes Buddha Parl)
  2. Bus 08: North Bus Terminal
  3. Bus 30: Thongpong – Tadthong
  4. Bus 32: Phontong
  5. Bus 33: Nongtha
  6. Bus 49 Nongteang)
  7. Bus 05 Namxouang)
  8. Bus 06 Pialard
  9. Bus 19 Paksap

North Stop (CBS1?)

Buses for Thailand etc. departs from here.

This is a little bit south from original position. Not far from.

This is a photo of CBS1. It becames a litlle bit messy, and tight place.

CBS North (CBS1?)

CBS North (CBS1?)

South Stop (CBS2?)

Buses for Friend Ship Bridge (Border gate place for Thailand), Buddha park etc. departs from here.

This is a little bit fat from original position. It is a road side bus stop rather than “Bus Station”.

CBS South (CBS2?)

The end of bus from Thailand which I rode was here.

By the way, old bus station place was like this. Entirly nothing.

So be careful if you will go Vientiane now.

Shops around CBS is crowded even now.

Salmon Sushi flavoured Potate Chips

サーモン寿司味ポテチ

Salmon Sushi flavoured Potate Chips

This is a snack sold in Seven-Eleven at Hong Kong. Salmon Sushi flavourd Potato Chips.
I’ve never seen in Japan. It looks good, so I tried it.

There was two bags in outer bag. One is a wasabi powder bag, and another is a potato chips bag. According to instruction written in back, I should put wasabi powder in the potato bag, and shake it.

Without wasabi powder, it tastes like an Ebisen. But aftertaste was like Salmon. I couldn’t feel “Sushi” flavour. (Also I don’t know what sushi flavour like…)

Wasabi powder was exactly wasabi. It was good. You should eat together.

BTW, why did they make a salmon sushi flavour snack rather than tuna or something?
There is many salmon menus in sushi restaurants. Are they popular in Hong Kong?

I visited Hong Kong (Hong Kong Pro-democracy Protests)

EYECATCH

HK-0006

Selfie! (A little bit outdated?)

I’ve seen around Hong Kong and Macau.
I have many purposes visiting Hong Kong like sightseeing, shopping etc.
But first of all, I’ like to write about Hong Kong Pro-democracy Protests.

Now Hong Kong is…

Currently (2014/11/22), I think everything in Hong Kong is normal except very limited exceptions. It is safe. If you don’t anything thoughtless things like violences or breaking something, it is okay.

There is so many photographers, and so many people taking picture with their smartphones. (Sure, I’m one of them.)

About protesting

There is two large demonstrators groups. One is around Mong Kok Station (旺角駅) at Kowloon. Another one is around Admiralty Station. (金鐘駅) Roads at both of them is blocked with a barricade. Mong-Kok is like an shopping street. Admiralty is the distinct of government offices and large banks.

Mong-Kok (旺角)

Barricade

Barricade

Mong-Kok is located at Kowloon area.

Here is an shopping street. There is many visitors and locals.
Cars were blocked by the barricades, but pedestrians can walk into there. Shops were open.

There is some people speeching, but so few demonstrating people. Here is relatively mild.

 Protester's Barricade and Polices

Protester’s Barricade and Polices

Left back side is the Protester’s Barricade, other side is polices and police’s cars. Pedestrians walks at the middle of them.

These cars are towards Protester’s Barricade. Many polices in cars.

Speeching Person

He was speeching in Chinese language (maybe). Polices listen his speech, but not tense atomosphere.
I didn’t recognize his speech because I didn’t recognize Chinese language.

People of the press climbling roof on Station Building

They probably want take good videos anyway. It is normal in here now.

Papers posted in a Bus Stop

There was so many things to protest.
Almost of them are in Chinese Language so I could not read them. But I could read Kanji, so I understood meaning of about half of them.

Some people said different thing than main stream protesting. Maybe person in this picture was saying about unfair treatment of a trial.

(Maybe) An Protest Blocking Roads by Hong Kong Protest

(Maybe) An Protest Blocking Roads by Hong Kong Protest

This is easy one to understand for us. Probably this says like “Return a right to use roads! I’m protesting blocking roads!”. (Perhaps misunderstanding…)

Admiralty (金鐘)

Admiralty Protesters

This is Admiralty which has government buildings, and many banks.
It is placed at north of Hong Kong island.

It was in night of friday, there was so many protesters. Some people was speeching central in this group.

They made stairway to enter the protesting place.

They were very thoughtful of safety, and of effectively saying to outside. Many things are made carefully, and thoughtful. It is awesome.

Many labeled Wall

Many messages were putting on this wall. Some of them written English, and Japanese Language.

My WordPress site has improved performance (In particularly Admin pages)

WordPress is too heavy for my small instance. In particularly Admin pages is heavy. Pages viewers is not really because of page caches. (These pages are heavy too when not on caches.)

However, I found a web page about WordPress running time. I installed a plugin “001 Prime Strategy Translate Accelerator” which introduces in the page then my WordPress web site improved a little bit. This plugin improve performance with MO files (translation files) caches.

I am using W3 total cache for overall performance. Some blogs say it is good for admin pages performance to disable Object Cache of W3 total cache. ( ((Japanese) WordPressの管理画面が重い場合の対処法) ) I did it. But I don’t know how good it is.

Some people might say anyone would not care about performance of admin pages. But I do. Because it makes me very frustrating. I gave up writing posts many times because of it.

Varanasi to Kathmandu, Mt. Everest

EC-HIMALAYA

I got out from India, go to Kathmandu, Napal.

Varanasi

Ganga

Ganga

  • I see Ganga (Ganges river). It is large river.
  • So many of f**king touts.
  • I visited Marnikanika Ghat. There is also so many cheaters here. They said they need money for wood to burn poor person’s bodies, or person who has no family. They are ABSOLUTE CHEATERS. DO NOT GIVE MONEY! NEVER!
  • They have no humanity. I hate them.
  • I went to airport just in time. But my flight (Air India) is delayed about half hour. I think staff (at least ticket counter staff) should tell me about that, but no kindly staff in there. Moreover, the flight delayed thirty minutes more. Silently.

Kathmandu, Nepal

Around Mt. Everest. It seems that a mountain in center which hides in cloud is Everest.

Around Mt. Everest. It seems that a mountain in center which hides in cloud is Everest.

  • It is a little warm than I expected. (But very cold in night and early morning)
  • I went to Mountain flight to see Mt.Everest by Buddha Air. But I can see only the foot of the mountain because of clouds.
  • It is very quiet than India! Also few garbases in road side. (It is like after festival moment in Japan) So many people cleans entrances their home.
  • Cars and motorcycles drives rough, but a little bit milder than India.
  • So many polices in roads. They do traffic control sufficiently.
  • Interruptions of the power supply happens very frequently. But I think it is almost same as Varanasi. (Perhaps it depends on seasons?)
  • Internet connections is good. Some WiFi spot reaches 700kbps. It is better than India’s hodel I stayed.
  • Many shops of SIM and Smartphones as same as any other cities.
  • So many cables above roads. Power line or signal line? How many used? How it made? It is mysterious.

I’ll go back to home tomorrow, via Delhi.

India Impressions And The SIM Card

INDIA-GATE

  • Many Indians.
  • I went to India Gate. No impression particularly.
  • Walk around delhi. Dirty. Bad smell. Danger. Violent people.
  • I went to Nehri Place which said indian “Akihabara”. They recommended me laptops many times. I don’t neet.
  • Breakfast was curry with something. Launch is McDonalds. Dinner is Domino pizza. I love america.
  • This hotel is a little noisy. Someone played music in midnight with large volume. It is hard to me. I’ll use earplugs.

Seriously India is best place ever visited. Very tired.

How to configure Airtel SIM

I had believed that it could use immediately after an activation without any configuration, but it is not.
We probably need to configure APN (Access Point Name) .

I configured it with my Xperia Z2, but other machines might be able to configure almost same way.

(1) Let’s activate as I wrote yesterday. (Insert SIM. Turn off roaming and Wifi. Call 59059 and answer the questions)

(2) Open [Setting] > [More…] -> [Mobile networks]

(3) Make sure that airtel is selected, It could from [Service providers] at (2)

(4) Open [Access Point Names] at (2)

(5) Tap add button, and enter below (Any other options than below should be keep in initial state. Maybe.)

  • Name: Airtel Internet
  • APN: airtelgprs.com
  • Proxy: 202.56.231.117
  • Port: 8080
  • MCC: 404 (Entered initially in my case)
  • MNC: 10 (Entered initially in my case)
  • Authentication type: Not set
  • APN type: default

(6) Save. I could use network with them. If you cannot, try rebooting.

Below is my screenshots of setting screens. (But it is in Japanese)

AIRTEL_XPERIA_1

AIRTEL_XPERIA_2

AIRTEL_XPERIA_3

Probably there is information about this configuration in airtel homepage or elsewhere, but could not find them. I found this config way with googling and try many partial information.

Some informaion says they send about configuration via SMS. But I could not receive them.

I’m in India

I’m very tired.

Some memos For person who will comes India whenever.

How to get out of airport and go to hotel

Many sites says that you will face some difficulties when getting out of the Indira Gandi International Airport. So you should ask pick-up service or something to your hotel. But I could get out and go to New Delhi Station with the Airport Express easily without any problems. If you will not arrive at midnight (The trains will suspend at midnight), it is probably good way. I think there is no need to stay airport until morning.

At New Delhi Station

You should leave this station ASAP. Sometimes many indians come here (Rush hour?). Many people push each other because there is no space to walk. Some people are fighting (literally). Station staff beats the counter window to banish people for some reason. Very fearful.

SIM Card

Today’s mission. Getting SIM Card. docomo (A mobile network provider in Japan) serves roming service in india, but it is too expensive.

I bought a SIM card at Airtel counter in the airport. It was easy. I showed them my passport. They take a picture of me. I told them my name, my father name and my hotel name. Then they wrote application paper for me.

AIRTEL

I bought around 6 pm. They said that I should call 59059 to activate around 9pm – 10pm.

First try is failed. It might be because of my roaming setting. Probably we must disable roaming when call them to activate. (They told me about the problem on the phone in English. But it is hard to understand to me…)

In second try, I switched off the roaming option, and selected mobile network to “2G airtel”. Then they ask me the expected question (Name, Father Name, Hotel Name). I could activated my SIM card correctly.

But I could not use their network. I will solve tomorrow because sleepy.

Difficulties to find my hotel

  • The hotel address shown at reservation site was different from actual hotel address.
  • The hotel place shown on google maps was different from actual place of hotel obviously.
  • The rule (or order) of address numbering is not understandable.

So I lost way because of these problems. I walked alone the town several hours at night. It might be so dangerous.

Eventually, I recommend you to ask pick-up service.

I had stayed four nights at “Hotel Private Affairs”. It is around 3000 yen per night. It was large room, good internet connection, good bathroom. This hotel might be good for business.

I bought GPS Logger (i-gotU GT-900Pro) & wrote reader program

i-gotU GT-900Pro

i-gotU GT-900Pro

Accuracy of my tablet’s GPS is bad. And app for recording is also too bad. So I decided to buy dedicated GPS Logger. I bought i-gotU GT-900Pro. It is watch type GPS logger.

Pros I think:

Cons I think:

  • A little bit large (It’s okay for me)
  • No way to erase GPS logs? (I don’t know. There is a hard reset but it maybe erases configure.)
  • Accessory software is for Windows-only. gpsbabel cannot read data from this device. (It means hard to use in Linux)

I hope to contribute OpenStreetMaps. There is not enough data of some isolated islands. Google Maps is not enough too.
(Currently, OpenStreetMap is better than Google Maps in some islands. But not enough for some islands.)

By the way, it cannot used with gpsbabel. There is some software for i-gotU series supporting Linux.

Former is GUI program written in Java. Latter is too old and maybe not working with GT-900Pro which is newer model. (And it could not build in my environment)
Probably there is no CLI program working with GT-900Pro.

So I wrote a small CLI program in Python. It can be downloaded in my Mercurial repository:

It can read data from GT-900Pro. Purge is not working now. I have been implementing it now. (It’s difficult…)

Visiting Tokyo Port Wild Bird Park

DSC_8631

Last Sunday, I visited Tokyo Port Wild Bird Park (東京港野鳥公園: Tokyo-kou Yachou Koen).
This park is in Oi Pier area. It’s near from Ota Market.

In this park, there is artificial tideland and a lot of birds in there. Also there are some huts and a visitor center for watching birds.

This park is not famous. So a small number of people is in there.
It is 300 yen for an entrance fee of this park. You can

You can visit here with walking 15 min from Ryutsu Center Station of Tokyo-Monorail. But it is a little far. So visiting with car or taxi is good choice.

There are two areas in this park, West Area (small) and East Area (large). When I visited, there are just few birds in West Area. But there are many birds in large East Area.

Birds in the park

I could not find it in this park, but there are some in Mizumoto Park in Katsuchika-Ku.
I want to go there next time.

Anyway, Tokyo Port Wild Bird Park is good place for bird lovers.

This article is continuation of “
Japan Median Tectonic Line Islands Touring (1) – Kamishima, Tojishima, Sakatejima

Kashiko-jima (賢島)

This island is in complex terrain area at Shima city. There is two road bridges and a railroad bridge between this island and the mainland. So this island do not looks like island. There is a lot of buildings like an aquarium (Shima Marine Land), resort hotels , sea-food restaurants and Pearl shops.
Not only this island, but also this area is famous place for pearls.

Masaki-jima (間崎島)

This island is also in cove at Shima city. It looks like connected with the mainland at first sight, but actually it is isolated.

It looks good place for sea bathing. There is facilities like lavatories and showers. The beach is clean and smooth sea because this island placed in a cove.

Also it is good place for walking, but there is only few rest places and promenades. It’s a little disappointing.

Basically it is an uninhabited island. But there is campsites and some old hotels (Probably they have not been in business).
