metro_wifi_tullys_nishi-shinjuku This cafe is very convenient for me to get free Wi-Fi and it is called "METRO FREE Wi-Fi", because it is close to Nishi-Shinjuku metro station. By the way, before users are authorized by the server, users can send ping any destination but aren't allowed to transfer any TCP/IP packets. It's to be expected that the provider wants to restrict the unauthorized user to prevent any unexpected and malicious behavior.

Logs of ping and ssh before I start to authorize:

$ ping google.co.jp

pebble_box The smart watch "Pebble watch" was delivered to me today from Amazon US. I think that Pebble is the best smart watch from among the other current smart watches available in terms of battery life. Pebble's uninterrupted usage time is about 5 -7 days, but others are about 1 -3 days. I'm interested in programming apps for Pebble, so I'm planning to look for instructions on how doing it this weekend. Anyway, I'm happy to get it (^_^) Thank you for reading.

seccon2014_xss_stage9 I participated in SECCON at the Japanese competition of information security with my colleagues as a team in 19th, July. The final ranking was 43 out of 425 teams. (Japanese official site)

We started from 9:00 and ended at 21:00 (12 hours!) so I was very exhausted but I was so excited when I was able to solve the parts of some problems. Moreover, I could improve my security skills and recognize my weak points in the field. It was a very valuable event. When I have a chance to attend such competition in the near future, I'll participate again and of course, I'll prepare by improving my skill every day to contribute.

I didn't go off the track from the main theme of meeting. The aims of the meeting are the following points: 1) Share the acknowledging and knowledge. 2) Come to a conclusion or next action plan after discussion. Especially, 2) is important for me because 4 days ago, I failed moderate the meeting and uphold the above point of view. From now, I will pay attention to moderating the meeting.

When I was a university student, I wrote the technical blog in this site to improve my skill and further my studies in programming, network, software design but recently, I can't write it constantly because I'm busy with work. Writing blog to study is effective for studying because you need certain stills to write a blog such as: 1. Gathering knowledge about a theme 2. Logical thinking and writing Now that I work for a system engineer in a bank and need to learn new skill, it is hard to take the free time after work. So I usually write articles in advance on Saturday or Sunday for three or four days as a buffer.

How to put off many books

I continue to clean up my room after I've moved to new house. I worry about how to put off many books that I brought from family home and I can't store in new house such as technical books and novels. It is "MOTTAINAI" to put off as dust so at first I'm planing to sell in Amazon market place but I recognize it is troublesome and low margin task with respect to spend much time to register the book, respond to buyer, send book, inform them. So I'll request to cutting vendors to cut books and after that I'll scan them as PDF or JPG data to read by some devices and I can save the space in my house.

From today, my sister and I have started to share our study progress in order to maintain our motivation to continue to study. Because we consider that it is difficult for us to maintain it after daily work by oneself. We choose Facebook groups as the tool to confirm our progress because it is convenient to share our daily progress such as "Today I've studied AAA" and "How to start to study is BBB". At first, we will try to use it whether it is an effective or not. After that, We'll rule about how to report our daily progress with trial and error.

Whilst I was working in the office today, I was asked to work jobs intermittently by colleagues and business partners. In order to finish the jobs effectively, I prioritize them. After that, I start completing them in order. This article was corrected by Satelle in Lang-8. Thank you very much.

28. It goes without saying that her condition is fatal. 29. Encountering a inevitable problem, we should solve it steadily. 30. What is juvenile delinquency caused by in the school? 31. "In all likelihood, my intuition will be right under these circumstances!" "huh..." "What!?" "Oh, Nothing in particular." 32.This seat is vacant because it's the priority seat. 33. If anything, I'm making much of quality over quantity.
