A techy story I heard from NTT Com's Eva Miyagawa at a bar in Nishi-Azabu

At the bar in Nishi-Azabu, the customer who was tilting the glass was Mr. Shin Miyagawa, a network evangelist of NTT Communications. Now, let's stop taking notes at the bar tonight and listen to Mr. Miyagawa's techy internet story with a glass in his hand.

Intro: At a bar in Nishi-Azabu

"(Is SDN or IPv6 visible in amber?)" (Miyakawa) "Ghee" (door sound)

"Not Casval, see, Mr. Miyagawa!" (Otani) "Oh, Mr. Otani" (Miyakawa)

"It's a strange situation. Well, please" (Miyakawa) "By all means, even in the old stories of the Internet" (Otani)

"Then, do you have a story that seems to be in storage today?" (Miyakawa) "I'm looking forward to it" (Otani)

Mr. Miyagawa who was a UNIX student and his pleasant friends

Mr. Miyagawa's encounter with the Internet dates back to the early 1990s. The seniors in the Department of Computer Science at Tokyo Institute of Technology, to which I belonged, all liked UNIX, and many were involved in the Japanese localization of UNIX. Mr. Miyagawa, who has been familiar with hardware and programming with 8-bit computers since he was a junior high school student, said that he was involved in computer research and development like a fish that got water there.

"I myself was doing mathematical logic in software engineering and was studying the automatic generation of programs. I learned the theory from my teacher, wrote software with a part-time job, and hardware at the robot technology study group of the circle. I had UNIX and network as sub-themes. "

"My teachers, Yoichi Shinoda (currently Hokuriku Advanced Science and Technology University) and Akira Kato (currently KMD Keio University Graduate School of Media Design), are the sources of SunOS 3.5 generated by the BSD version of IBM AIX and reverse compilation. I had the code. Professor Shinoda translated X10, the predecessor of X11, into Japanese in 3 days, one senior had a code conversion called nkf, another had a k14 font, and another had a xterm called kterm. I was making verbalized versions, and I was releasing these as free software. "

At that time, Professor Jun Murai of the WIDE Project moved from Keio to the University of Tokyo through an assistant at Tokyo Institute of Technology, and Professor Hideki Yamaguchi ((then: Graduate School of Osaka University, now: Professor of Nara Institute of Science and Technology)) and Professor Hideki Sunahara ( At that time: Keio University Graduate School Assistant to Telecommunications University, now Keio University Graduate School of Media Design Professor) was also a graduate student and at most an assistant (current assistant professor). At that time, my seniors recommended me. , Contributed to magazines and books.

"You should go in and out of ASCII and write an article? I started going to ASCII in Minami Aoyama long before Mr. Otani entered. Before and after that, my classmate who was working part-time in the A edition at that time. So, I'm going to talk to ASCII editor-in-chief Hortens Endo about FM synthesis. I made my debut not with monthly ASCII, but with a serialization that evaluates each company's workstation in UNIX Magazine, and it continued for quite a while. We were working with people such as Katsuhiko Gondo (currently a professor at Tokyo Tech) and Takashi Imaizumi (currently a professor at Chiba University) in the laboratory. "

"I had a series of evaluations of each company's workstations in UNIX Magazine, and it continued for quite a while."

"I was invited by my seniors in the laboratory, Takeshi Hatayama (currently the director of the NTT DATA Quality Assurance Department) and Masahiko Tomoishi (currently a professor at Tokyo Institute of Technology), to join the PC98 version of the MINIX transplant team. That's why I was also involved in MINIX 1.5 published by ASCII, and I also published "Book for using MINIX 256 times" (published by ASCII). At that time, the architecture of MINIX changed from 286 to 386. Around that time, protect mode was available and the address space expanded. At that time, Linux was born as an alternate kernel for MINIX. "

"A long time ago, I talked with Ogo-chan (Mr. Masami Ikukoshi, the first chairman of Linux in Japan), but the early code of Linux is often a little itchy for people who were doing computer science. There are a lot of things that go beyond memory management and let processes go directly to I / O, or is it something that shouldn't be done? But, for example, if you make a system call to draw X Windows. It was designed that way because it would be slower. In other words, it seemed like the idea of ​​ignoring security to some extent and doing what we could. "

"I can't think of it in the current distribution, but when I install Linux, it's normal for anonymous FTP to go up, or whatever. I wonder if this is okay, but 386BSD comes out and I can go with it. So, when I started working on 386BSD when my master's degree was over, and when I started serializing it in the magazine "Super ASCII", I was just getting used to TCP / IP technology. After that, "Book for using BSD 256 times" I also wrote. "

Doctoral course that discovered the appeal of TCP / IP and the potential of the Internet

In the early 1990s, when I was living a UNIX-immersed student life, TCP / IP emerged as an Internet protocol in place of UUCP. As the implementation of TCP / IP has been refined, even at Tokyo Institute of Technology where Mr. Miyagawa was, we will set up Ethernet by ourselves, draw a dedicated line of 64 kbps, and form a TCP / IP network between universities. Became. This will become the foundation of Japan's Internet.

"Sure, I think the University of Tokyo, Tokyo Institute of Technology, Kyoto University, Keio University, and Osaka University were connected. So, try mounting the file system of the University of Tokyo with NFS from Tokyo Institute of Technology, or finger command a friend in Hongo University of Tokyo. I broke the screen with the talk command and threw it at "I'm going to swallow it now" without worrying about people's inconvenience. I thought that TCP / IP was interesting. TCP / IP network I used email, FTP, Telnet, IRC, etc., and the doctoral course was over when HTTP came out. "

"Professors Murai and Sunahara have also begun to say that the Internet was only connected to universities, but from now on, they will also be doing commercial business. IIJ was established, and AT & T's JENS landed before and after. Around that time, NTT also started connecting with TCP / IP. This was around 1992-3. I still remember IIJ's first service. After all, Mr. Takamichi Mitsuzen (currently a senior in the laboratory) IIJ Managing Director) came to carry the router (laughs). At that time, there was no Interop yet, and an event called "UNIX Fair". I also had a cable on site. "

Mr. Miyagawa, who is obsessed with the appeal of TCP / IP, continues to hone his network skills in the field while being a student. Meanwhile, she worked on TCP / IP networking at Tokyo Women's Christian University.

"At that time, my father was the dean of the Tokyo Women's Christian University. Apparently, the story of TCP / IP conversion of the campus network came up, and when I got home one day, my father asked me," Are you good at UNIX? " When I asked him why he knew UNIX because his father was a liberal arts student, he said, "Miyakawa's son is familiar with TCP / IP, so please help me." I was told that I was asked. "

With this connection, Mr. Miyagawa, who was a second-year master's student at the time, will be involved in the introduction of UNIX machines and TCP / IP conversion at Tokyo Woman's Christian University. Since the computer center of Tokyo Women's Christian University does not have the know-how, Mr. Miyagawa designed the campus network, acquired the domain name, and drew a dedicated line to connect with the outside. He worked with vendors to direct the introduction of network equipment and workstations, and even made the config. Through this experience, Mr. Miyagawa realized the impact of commercialization of the Internet.

"At the time when computer communication such as Nifty-serve and ASCII-net was in its heyday. What is the Internet for ordinary people? But I had the intuition that this would be something that everyone would use. It was a religious experience in a sense that I was convinced, not something like that. When I was young, I was really happy to meet the technology that will come 10 years later. "
