It is an awesome talk. I have never thought to find heroes and nurture them in a community. But now I understand the importance of heroes as a community manager.<br />
Get them connected with each other/Challenge them/Nurture them/Help them inspire future generations;<br />

He introduce to make a Facebook application using Heroku. His presentation in Japanese can be found in his blog. <a href="http://blog.candycane.jp/archives/1496">http://blog.candycane.jp/archives/1496</a><br />

I followed his explanation and click them. What you need is 1) github account, 2) heroku account, 3) Facebook account, that's it. You could make a Facebook application without any coding. very simple.<br />
<br />
The application which I made in Five minutes is the following. It is a tutorial of Facebook application.<br />

I am using Mac Book Air since last friday (April 13, 2012). Although I used Mac and Powerbook in early '90, it is the first Apple product in 21 century. I don't use iPod, iPhone, iTunes, iPad, nor any of Apple products.</div>

Last weekend I set up new Mac Book Air (mba, here after). By the way, it is a corporate computer so I don't pay it. I had wanted to make software development environment, so did google. I learned Xcode is popular tool. So I tried to download and install it.</div>

You need Apple ID to download it. What is Apple ID? You need to register developer's site to install it. In order to register Apple ID, you have to provide your name, address, birth of date, telephone number and/or credit card number, and so on, to Apple, Inc. In order to register developer's site, you need to provide your Apple ID, affiliation, interests, development OS, products information, many personal information to Apple, Inc.</div>

I have a netbook which is built by Asus. When I started using it three years ago, I did not accept Microsoft agreement which means that Windows were erased from my netbook and I didn't use Windows on it but I installed Ubuntu. So I have never provide my personal information to any companies, like Microsoft nor Asus.</div>

Thanks Ryoko Akaike<br /><br />HIGHLIGHT<br /><br />This explains the debug techniques fully under the long term development of Linux Kernel and application development process. This book covers the necessary preparation, its knowledge, quick finding tools of problems and how to solve them quickly by using the most useful techniques and tools. There are many examples to be used in the book. This book helps the Linux development engineers.<br /><br />Mr. Yukihiro Matsumoto, creator of Ruby strongly recommends this book for the process of programming development.<br /><br /><br />DESCRIPTION<br /><br />This book provides the feature of the debugging techniques of Linux development<br />Engineers.<br />The readers can :<br />- Know how to find the problems.<br />- Prepare for the knowledge to find the problems.<br />- Find the bugs of the system.<br />- Amend the problems.<br />- Get the useful techniques and tools.<br />- Get the most effective tools in the development stage.<br /><br />Master the problem solving techniques by the detailed examples.<br /><br />ABOUT THE KEY AUTHORS<br />Mr. Hirotaka Yoshioka<br />Dr. Kazuhiro Yamato<br />Mr. Naohiro Ooiwa<br />Mr. Toyo Abe<br />Mr. Shunsuke Yoshida<br /><br />All engineers belong to Miracle Linux Corporation, which provides the Linux<br />System packages and its global consulting services of Linux to the various<br />Corporations in Japan.<br /><br /><br /><br /><blockquote></blockquote>hyoshiokhttp://www.blogger.com/profile/10003071216648195544noreply@blogger.com8tag:blogger.com,1999:blog-2166105636130114826.post-42766155036806174812009-04-25T11:21:00.002+09:002009-04-25T11:27:29.055+09:00Debug HacksDebug Hacks is a book to introduce tips and tools for removing bugs. Debugging is one of time consuming process in the software development. However there is few books to describe debug.<br /><br />Debugging is a kind of black art. We have never been taught in a class room. We need to have debug skill. Each programmer has own debug techniques but almost nobody try to describe their tips.<br /><br />This is our challenge to describe the art of software debugging. The authors are linux kernel engineers of Miracle Linux Corporation (<a href="http://www.miraclelinux.com">http://www.miraclelinux.com</a>). I am one of the authors :-)<br /><br />It covers from C/C++ application debugging to the Linux kernel debugging. We show the real world examples which we have fixed in our services.<br /><br />Chapter 1 Warmingup, Chapter 2 Preparation for user land programs, Chapter 3 Preparation for kernel debugging, Chapter 4 Debugging for Application programs, Chapter 5 Debugging for Kernel Programs, Chapter 6 Various Tips and Tools.<br /><br />This book covers GDB, strace, objdump, Valgrind, kprobes, jprobes, KAHO, systemtap, proc file system, oprofile, VMware vprove, fault injection, Xenand so on.<br /><br />You will learn many tips to debug your programs.<br /><br />Bad news is that it is written in Japanese. You may ask O'reilly Japan to translate this book to other languages, that is, English, Chinese, Korean, and so on.<br /><br /><iframe src="http://rcm-jp.amazon.co.jp/e/cm?t=dhatenejp015d-22&o=9&p=8&l=as1&asins=4873114047&fc1=000000&IS2=1&lt1=_blank&m=amazon&lc1=0000FF&bc1=000000&bg1=FFFFFF&f=ifr" style="width:120px;height:240px;" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"></iframe>hyoshiokhttp://www.blogger.com/profile/10003071216648195544noreply@blogger.com2tag:blogger.com,1999:blog-2166105636130114826.post-8135645016772230072009-03-11T18:04:00.005+09:002009-03-11T18:25:21.486+09:00YLUG (Yokohama Linux Users Group) and Kernel Code Reading PartyThis memo is inspired by the blog written by Ted.<br /><a href="http://thunk.org/tytso/blog/2009/02/04/how-active-are-your-local-linux-users-groups/">http://thunk.org/tytso/blog/2009/02/04/how-active-are-your-local-linux-users-groups/</a><br /><br />Let me describe Yokohama Linux Users Group (YLUG).<br /><a href="http://ylug.jp/">http://ylug.jp</a> (Many pages are written in Japanese)<br /><br />More than 10 years ago, I was living in the Silicon Valley and worked for an RDBMS company as a RDBMS kernel engineer. My job was nothing related with Linux. It was 1998. Netscape opened the source code aka the Mozilla Project. <a href="http://www.svlug.org/">Silicon Valley Linux Users Group</a> had an offline meeting which hosted Marc Andreessen of Netscape who made this crazy idea on April, 1st of 1998. Marc said, "It is April, 1st, it is not April Fool but real." I know nothing about Open Source nor Bazaar model at that time.<br /><br />I came back to Japan on the end of 1998. There were Linux bubble and many LUG (Linux Users Group) in Japan were established.<br /><br />YLUG (Yokohama Linux Users Group) is one of LUG which was established in January of 1999. I joined YLUG. Mailing list was very active in those days. I asked an easy question to the mailing list. How does the linux kernel implement a system call? The answer was "int 0x80" and "read the source code." Hmm, I find/grep "int 0x80" and browse the code. I happened to think that it might be fun to read the code with YLUG members. It was a little bit bother to read the code by myself, but reading the code with colleagues may give us other insight. It might be fun.<br /><br />So I set up an offline meeting to read and have a party. It was held April 28th, 1999 and more than 30 people joined it. It was *fun*. Many people said, let's have another one. Many who could not attend the meeting asked us to have another one. We have more than 90 times and almost once a month since then.<br /><br />I named it "Kernel Code Reading Party."<br /><br />Although, we have not read the code these days, Kernel Code Reading Party has two parts, 1) a speaker makes a informal technical seminar, 2) we have a beer party. We will have 10th anniversary and 100th Kernel Code Reading Party in this October or November time frame.<br /><br />From Junior high school students to 50 something like me, from linux beginners to kernel hackers, audience are very wide.<br /><br />YLUG's Kernel Code Reading Party is very active and we really enjoy it.<br /><br /><a href="http://someday-join-us.blogspot.com/">Someday Join Us</a>.hyoshiokhttp://www.blogger.com/profile/10003071216648195544noreply@blogger.com1tag:blogger.com,1999:blog-2166105636130114826.post-67015825895257570082009-03-09T15:44:00.000+09:002009-03-09T15:54:29.905+09:00Let's Get StarttedHi,<br /><br />okdt recommended me to write a blog in English. so here it is.
