지난주 테르메덴으로 스파와 온천을 즐기러 가던 길에 만난 짤막한 산길을 소개해드립니다.

카메라가 없어서 경치를 사진으로 담아오진 못했지만 단풍이 들어 곱게 들어 매우 아름다웠습니다. 골프를 좋아하시거나, 온천을 즐기러 가실때 단풍지기전에 한번 들러보시는것도 ..

테르메덴은 위 지도 도착지점에서부터 2 ~ 3 km 가량 마을을 통과 한 후, 좌회전 하시면 됩니다.

Subversion Submitted to Become a Project at The Apache Software Foundation

Subversion Submitted to Become a Project at The Apache Software Foundation

Today, I noticed that Subversion proposal/vote was opened in the general mailing list of Apache Software Foundation.

Hi all,

The Subversion Corporation decided recently to submit Subversion to
the Apache Software Foundation. I've sent the initial proposal to
Apache's Incubator project requesting the move (see below).

There are a lot of ramifications to this step. It would take me quite
a while to write this email if I detailed this stuff. In short, there
will be *no change for users*. This will primarily impact the
development community.

Please stay tuned for more info!

Thanks,
-g

버전 관리툴로 잘 알려진 Subversion이 Apache Project로의 제안이 제출되었습니다. 아직 투표가 진행중이지만, 거의 100% Apache Subversion이 확정된것 같네요. :) 오픈소스는 ASF가 짱 먹을려나 봅니다.

카트라이더.. 한번쯤은 해보셨죠?
처음엔 무척 재밌습니다. 그런데 course 를 다 외워버리고 문득 무한 루프안에 있음을 깨닫게 될때, 우리는 질려버렸다라는 표현을 사용합니다.

요즘 제 삶이 그렇습니다.
왠만큼 이름난 도로란 도로는 다 다녀본것 같습니다.
명소지란 명소지는 다 다녀본것 같습니다.
직장일도 이만하면 많이 한것 같습니다.
맛있는 음식들도 실컷 먹어 보았습니다.

이제는 더 이상 갖고싶은 물건도, 욕심도, 무엇 하나 어디 새로운게 없네요.

지금까지 너무 쾌속질주 해온 것 같습니다. 여기서부터 이제 삶의 끝까지는 과거 한번쯤 겪어본 희노애락의 무한루프가 될 것 같다는 생각만 듭니다.

한마디로 질리기 시작하네요.

Microsoft to Cooperate Closely with Korean IT Biz/ Steve Ballmer, CEO of Microsoft

2009-11-02T04:08:00.000-08:00

Steve Ballmer, a CEO of Microsoft, recently visited Korea and exchanged a memorandum of understanding (MOU) with the Korea Agency for Digital Opportunity and Promotion (KADO) on cooperation in easing the digital gap in the domestic market.

(picture from the rr.com)

Meanwhile, The media of Korea, announced about it with a provocative subject as below:
Steve ballmer said, "Google have to learn more from us"
omg, You've shamed me.

----
Interviewed by Lee Gwang-jae Reporter / voxpop@ittimes.co.kr

Q: Would you briefly explain your purpose of visiting Korea and results?

It is my first visit to Korea since 1998. I don't think I have enough information on the Korean market, dubbed the world's greatest IT powerhouse? My visit is to see firsthand and figure out the Korean market and at the same time to seek partnerships with the Korean government and businesses. I?e had a good chance to learn about Korea's IT industry developments. Negotiations with the government and industry have progressed smoothly.

Q. Which cooperative areas are you discussing with the Ministry of Information and Communication other than removing Korea's digital gap?

The partnership will start with easing the digital gap. I appreciate that Microsoft has a chance to contribute to easing the digital gap in Korea. I am especially impressed by the next generation growth project, the IT 839 Strategy", introduced by MIC Minister Chin Dae-je, and will seek ways in which Microsoft can cooperate in that area.

Q. Any possibility of a Microsoft R&D center in Korea?

We call R&D centers outside the U.S. Innovation Centers" Any projects in Korea will be considered depending on the performance of innovation centers in Europe. Minister Chin proposed an X-BOX and online game-related R&D center construction. We are encouraged by the affirmative response by the Korean government for our whole investment plan due to the copyright issue.

Q. Are you consideing partnerships with domestic telecommunications firms such as KT and SK Telecom?

We have already had business ties with KT, and have a chance to cooperate with SK Telecom. We have common interests in many sectors with Korean concerns and a new business opportunity will be created in the mobile telecom network field. Negotiations will be made with the industry to supply new technology for integrated networks.

Q. What is your opinion on the Korean government's open software support policy?

It is desirable for the Korean government to be open-minded toward all kinds of software. By software, I mean all kinds of commercial software, including that from Microsoft, from which job creation and economic growth is possible. Korea has a high-level commercial software industry, including exports. The government should encourage the use of open software to stimulate industry growth. A problem may occur when the government takes the side of a certain industry. I don't think that the Korean government would do so and implement policies hampering industry growth.

Q. What do you think about the Korean Fair Trade Commission's probe of MS Messenger's option item" sales practice?

The Korean government does not have a very different view from the EU's executive commission. Leading businesses with high market share should also be guaranteed in their work enhancing their products' functions. Only the benefit of consumers matters. We are cooperating with the investigation process. The US federal court made a decision in favor of Microsoft recently and we expect that the Korean government will file a similar ruling in the Messenger case.

백악관 사이트의 새로운 검색엔진, Apache Solr

2009-10-25T18:55:00.000-07:00

O'relly 에 따르면 Apache licensed 검색엔진 공개 소프트웨어인 Solr이 White House 검색엔진으로 사용된다고 합니다. -- Thoughts on the Whitehouse.gov switch to Drupal

대조적으로 '정부 프로젝트는 눈 먼 돈'이라는 말이 있듯, 알아서들(?) open source를 활용하되 그것을 바닥아래 몰래 숨겨 프로젝트 몸집만 부풀리는 한국은 여전한것 같군요. 비단 정부 뿐 아니라 사실 한국은 기업부터도 그러한 것 같습니다. open source를 core components로 활용하면서 순수 기술력의 성과라는 과대 포장과 함께 open source는 한마디 언급하지 않는 모습을 보입니다. 누가 잘못됬다라기보다는 IT 사회 전반의 인식 문제 같습니다.

요즘에 대한 Report

2009-10-10T04:29:00.000-07:00

1) 오늘은 전화하다가 전봇대를 들이받은 하루였다. (-_-;) 나름 애정을 두던 차라서 마음이 쓰라리다. 물리적인 상처는 정신적인 상처로 연결된다.

2) 곧 BSP library와 distributed graph computing 분야에서 Mr.Choi 의 화려한 등장이 예상된다. 내 생각에 이것은 분명 Hadoop cluster 위에 M/R만으로 가렵던 부분을 벅벅 긁어 줄 수 있는 막강한 도구로 자리매김 할 것이라 확신한다. (유사품에 속지 마세요) 절대 어느 누구도 본체만체 할 수 없는... 역시 이건 내 인생에서 가장 즐겁고 신나는 일이다.

3) 사내 일상에 대해서는... 반전이 있나? 싶었으나 나의 초강력 prediction system(이라봐야 허접한 짱구 굴림이지만)으로 연산해본 결과 결국 변한건 or 변할건 없어보인다에 올인.

4) 주식 보유수, 계좌 수, 도메인과 사이트수가 점점 많아짐과 함께 고민과 지출, 빚도 많아지고있다. 아마 한가지 문제만 잘 처리되면 완전무결한 무위도식의 plan이 가능해질것같다.

Friend Suggestion using Hama

2009-10-06T19:39:00.000-07:00

SNS market share is similar with othello game. It means that the adjacent people could change you. Therefore, to prevent emigration from your service, you need to recommend a couple of people to user. Don't leave them alone!! For the gradual settlement of the Social Network Service, Friend suggestion might be a solution or useful tool.

It's a slide on conceptual design stage. The main idea is the k-plex clustering to find out the communities, and then friend suggestion among the people who don't know each other in community.

I'm still updating.....

Hamburg, will be integrated to Apache Hama project soon.

Hamburg is the BSP based graph computing framework on top of Hadoop. We're working on the perfection of a project as a open source. Since the matrix is the great tool to store graph data and process them, we thought the idea of dealing with graph and matrix at one place.

왜 Social Network Service는 흥행하나?

2009-09-15T08:31:00.000-07:00

오늘 굳 가이 '현식 초이' 와의 대화중에 twitter같은 사회 networking 서비스의 흥행은 “사람이 본능적으로 남과 소통하고 연결되고 싶어하는 성향이 있어서”라는 의견이 인상에 깊이 남았다. 물질과 반물질, reductionism으로 내려가서도 생각해볼수있는것인가?

뭐 쉽게 그냥, 아무도 봐주지않는 속옷 패션에 신경쓰는 일이나, 관찰자가 없는 블로그에 포스팅하는것만큼 재미없는 일도 없을것이다. 없는것과 마찬가지니깐.

어쨌건, 미래의 mobile 기기에 관심이 조금씩 커지고 있다. 왠지 2~3년 내에 그 변화를 느낄수있을것 같다. (이미 다가와있는것인지도)

Is this the new venture or just another desperation?

2009-09-15T07:56:00.000-07:00

Recently, I'm trying to figure out another (better) life since I've lost my passion for company.

Of course, despite some failures (e.g. global services), this company has had quite a good year on balance. And, this company is still one of the largest enterprises of its kind.

Well, IMO, the problems are partly due to bad (conservative) management. There's no room for new talent. The fact that many people also think like me adds conviction to my view.

However, I have no plan yet and don't know whether it is right or wrong. Is this the new venture of just another desperation?
