See you at MVP Summit

2005-09-25T21:56:00Z

I will attend MVP Global Summit, Seattle. This is my third time to attend the summit. I'm very excited because I can get a chance to meet very famous developers, e.g. John Robbins, Don Box. At last summit, at the opening event I saw a person an thought I knew him already, but I had never met him before, and I finally knew I saw him on the cover of Profession C#(Wrox Press). Hahahaha.

I'm very looking forward to seeing you at Seattle. :-)

The Memory Jogger™ II

2005-08-17T10:48:00Z

Do you know 'The Memory Jogger™ II'?

Today, there was a seminar about Software Estimation. During the seminar, the speaker explained the way the CMMI level 5 company estimates many attributes of quality. Anyway, he introduced many charts that the company uses to express its attributes, and I asked how many charts there are. He said there are many charts and also give me a little pocket book as a sample.

I think if you are interested in Software Estimation, maybe, you already might have known or heard about it. I didn't dig into the book, but as the speaker said, I think it will be helpful. So if you are interested in this book, visit homepage, http://www.amazon.com/Memory-Jogger-II-Michael-Brassard/dp/1879364441.

It was raining...

2005-07-09T03:55:00Z

Yesterday, I had a heavy rain. It was a sudden shower. I was waiting a bus for Suwon, standing in a line. There was a person who didn't have a umbrella, so I let him under my umbrella. I like the way that I can get together with a new person naturally. Anyway after getting on the bus, I sat down next to him. We said to each other about something, you know, it's about the company, the reason he didn't have a umbrella, where he lives, something like that. But not in 5 minutes, we was unable to keep the ball running. He was working for a foreign company. You know, I want to work for a foreign company, so I asked about many things like how difficult the interview is, what attitude I need to succeed, and some thing like that. He really gave me good informations, and I think it will be helpful for me someday.

Even if it was a small thing that I let him under my umbrella, I got very useful informations with Starbucks Coffee. :-)

Attending Korea Computer Congress 2005

2005-07-05T12:25:00Z

I'll attend the Korea Computer Congress 2005 from this Wednesday to Friday. This is first time, and I'm just curious what will be on there. There will be more than 5 sessions and I'll attend one session which introduces Computer Languages. In fact, I'm not interested in that field, but there is nothing but that session that is worth attending. Anyway, I'll have fun and really enjoy the KCC.

Preparing seminar.

2005-07-04T09:29:00Z

On next Monday, there will be a seminar at KITRI. If you are not a Korean, you maybe don't know what KITRI is. It's like a insitute for a person wants to get a job, but didn't have a job, yet. I'll give them a presentation about debugging and what the programmer is for about 3 hours. So I'm now preparing the seminar. It will be a good time for me to share my skill with beginners.

Look for the silver lining...

2005-07-01T12:55:00Z

Did you ever listen to the 'Look for the silver lining' that is part of O.S.T of L.A. Confidential. I love its lyric.

Check it out and if you like it, buy the O.S.T. CD(of course, I'm not doing advertise it)

Look for the Silver Lining

As I wash my dishes,
I'll be following your plan,
Till I see the brightness
in ev'ry pot and pan.

I am sure your point of view
Will ease the daily grind.
So I'll keep repeating in my mind:

Look for the silver lining
When e'er a cloud appears in the blue.
Remember somewhere the sun in shining
And so the right thing to do
Is make it shine for you.

A heart, full of joy and gladness,
Will always banish sandness and strife.
So, always look for the silver lining
And try to find the sunny side of life.

Look for the silver lining
When e'er a cloud appears in the blue.
Remember somewhere the sun in shining
And so the right thing to do
Is make it shine for you.

JoelOnSoftware

2005-06-29T17:42:00Z

Did you hear about the JoelOnSoftware. I think many of you already heard about it. From yesterday I have read Joel's book. He is very good and famous writer. He explains many things related software(and development). There are many interesting topics, but I won't read it during a day because it gives me a idea and I want to understand what Joel wanted to tell me in his book. I just read a topic a day.

If you are a Korean, you can get the book translated into Korean. :-)

Off-by-one error

2005-06-07T13:54:00Z

A friend of mine asked for me to solve his bug, saying that he is suffering from it. You know, I am running my own site, Debuglab.com, and he posted the bug. When I read the problem statement, I could find off-by-one error.

HRESULT CFileUpload::_MultiToWideChar(PBYTE _pbytStartPos, PBYTE _pbytEndPos, LPWSTR &_pwszBuffer, LONG &_nLenOfBuffer)
{
...
if(NULL == _pbytStartPos || NULL == _pbytEndPos)
{
   _pwszBuffer = L"";
   hr = S_OK;;
   goto _FUNC_END;
}

bytTemp = *_pbytEndPos; //Exception

*_pbytEndPos = '\0';
}

and the code calling that function is the following.

if(FAILED(_MultiToWideChar(&vecFormData[0], &vecFormData[vecFormData.size()], pBuffer , nLenOfBuffer)))
{
goto _FUNC_END;
}

Can you find a bug in this source immediately? I did. It took only 3 seconds. This is the traditional off-by-one error. If you are a C++ programmer, you know that every array's range is from 0 to n-1. But in this source the programmer ignored or missed the basic concept.

&vecFormData[vecFormData.size()]

I bet this code should be like the following code.

&vecFormData[vecFormData.size()-1]

Not -ed, but -ing.

2005-06-06T15:01:00Z

Yesterday, while I was talking with girl friend, I said to her that I want to be a -ing person, not -ed person. What is -ing person? It means I want to and should keep doing my best.

* Today's good expression :

The haves and the have-nots.

I'm little tired.

2005-06-05T13:17:00Z

I have four day's holiday running from last Friday to next Monday, so I think this holidays will be the rest from the hard work, but it went wrong. Today I went to the my girl friend's home, Dangjin, in Chungcheongnam-Do. It took about 2 hours, originally it should be about 1 hour. Anyway, when we arrived, it was 1:00 p.m., and after 4 hours I left for Daejon.

Tomorrow, I'll study for this semester final exam. There will be four exams next week, the week of final. :-(

Sleepless in Daejon

2005-06-01T16:17:00Z

I don't want to go to bed. It's too waste to sleep in my life. There are so many things that I want to do and should do, so in these days I go to bed at 3 a.m. or 4 a.m. and get up at 9 a.m. It's only 5 hours. Do I need to take a nap during day? No, I don't.

I'm a loser.

Do you like to play soccer? I love to play soccer! There was a soccer league at KAIST from March to May. Our team had six games with other laboratory teams. During the league, I scored 6 goals and 2 assist. The record is not bad, it's almost on the top ranking. Today, I had a semi-final game, and our team was defeated by 5. I did my best, but the competitor was very strong.

Translate some articles

2005-05-30T11:43:00Z

As a .NET Advisor, I just translated some article from MSDN into Korean. It was kind of easy work.But whenever I translate, I feel I need more time to make the article more easy to read. As you know there are a little difference between English and Korean. I need to have a knowledge of literature.

Anyway, here is the articles that I translated.

I just arrived in Daejon from MVP Singapore Summit!

2005-04-28T07:58:00Z

On last Sunday, I went to Singapore to attend MVP Asia summit. It was my first trip to Singapore. Before I went to there, I collected many informations about Singapore and it gave me idea how I could enjoy this trip. Above all, Singapore is very hot and very humid. I can't help taking a shower every day!

Overall, this summit was pretty good (8 or 9 point). Thank you, Cally Ko, ASIA MVP Lead. The best section, I think, is .NET Tips & Tricks. I like to hear from MS employee, of course, but some sections are a little boring to me. I want to some pics on this blog, but it would take some time because I don't have a digital camera (I lost it!).

Before I left Singapore, I asked some MVPs if they have a plan to attend MVP Global Summit and they answered 'yes', so I'm looking forward seeing them. :-)

I'm going to be a graduate student at KAIST!

2004-12-10T09:27:00Z

Have you happened to hear about KAIST? If you live in Korea, I bet you alreday did. Finally, I get the chance to study at KAIST next year! I'm a lucky guy!

Winter is just around the corner!

2004-12-07T23:09:00Z

In Korea, Winter is just around the corner. It's getting cold, but I didn't prepare for Winter. 1 week ago, it snowed a little. Because my girl friend wanted me to come to her when it snows, I ran to her with a big present, me. :-)

I prefer Summer to Winter.

We need Hands-On-Labs about Debugging.

2004-12-07T12:02:00Z

Many developers that I have met before want to get HOL materials about debugging. They already know what they want to have, but ,you know, debugging is kinda special thing that we can only get the idea by exercising something. We just need many examples and case-studies, so I am going to make HOL from scratch. Any idea? or Any help?

New site open! www.debuglab.com

2004-01-29T17:46:00Z

I just opened my web site (www.debuglab.com). This site is only for debugger(not TOOLS but guys), especially interested in .NET technology. If you have any interested in debugging, please visit my web site. One more thing, you should read Korean. :-)
