Showing up in the news

Situation in the situation room

Power supply/demand situation is getting a bit tight in Korea this year - there's this unusually hot weather coming up, and several large nuclear plants got shut down due to faulty parts being put into due to corruption.

As a result, power grid situation room is up and running early, and I'm taking part in the operation. This means I'll be showing up in the news broadcasts a few times throughout this summer. Yesterday saw some significant coverage from the media, and here are the results.

Tool-Box.info is back online

wesley96@gmail.com (Wesley) — Mon, 25 Mar 2013 11:06:00 +0900

Wesley's Tool-Box was offline for a 53 days since February 2, 2013, when the iMac (Early 2008) that ran the website since May 2008 broke down.

Replacement system was sought, and a souped-up Mac mini (Late 2012) was chosen to pick up the task. Unfortunately, there had been a few issues - recovering the files and database from the iMac didn't go as smoothly as planned; Mac mini didn't get along with certain brand of SSD; family stuff.

All that's behind now. Enjoy the site once again - thank you for your patience.

Full moon for Chuseok holidays

Bright and full, as I wish everyone to be. Photo taken with my Kodak camera on max zoom.

iPhone 4 + $40 telescope yields some more detail of the moon's surface. Click for full resolution.

Chuseok (Korean thanksgiving) holiday week is closing, but the weather cleared up and I had the opportunity to snap some photos of the full moon. The $40 toy telescope acting as a makeshift zoom lens for iPhone 4's camera worked okay and reveals lots of details. Enjoy!

"화제의 전력인" 정우덕 대리

1년만에 신문에 인터뷰 기사가 실렸습니다. 전문지인 "이투뉴스"에서 지난 8월 중순 아이폰 앱 개발한 것과 관련하여 인터뷰를 가졌는데 얼굴과 함께 실어주었네요. 안타깝게도 지면으로 발행된 것에는 제 이름이 잘못 나가는 바람에 ("조우덕"이라...) 한바탕 해프닝이 있었습니다. 온라인과 PDF 버전은 수정 요청해서 제대로 나오고 있습니다. 자세한 내용은 아래를 참고하세요.

App now listed in "What's Hot"

wesley96@gmail.com (Wesley) — Thu, 02 Sep 2010 13:02:00 +0900

Korean Power Grid Info is selling like hotcakes (click for full screenshot)

A couple of days ago, before end of August, Korean Power Grid Info app for iOS devices surpassed 2,000 downloads. That took only about three weeks, and considering the somewhat obscure nature of the software, I think it's selling pretty well. It's consistently present in top 50 free downloads chart in the Business category. I think the word is going out somehow, and there's always quite a bit of people who download it every day.

Now, it seems that Apple has noticed this and put the app under "What's Hot" section of the Korea iTunes App Store's Business category. That's pretty hot! I'm glad it's getting a favourable recognition. Thanks for everyone who downloaded.

Selected again - this time in US App Store

wesley96@gmail.com (Wesley) — Wed, 11 Aug 2010 09:18:03 +0900

Recognized in the USA, too (Click to enlarge)

I suppose the Korean Power Grid Info app isn't particularly interesting to the people in the United States. The rank has been steadily moving down (started at 113, now at 160). Maybe I need to find a way to let the folks in the power grid business in the US know about the app? Still, at least I can take comfort in the fact that the app will nevertheless be staying on top of the Business category for a while. The Apple has selected it as "New & Noteworthy" for the US App Store, as well. Thanks for recognizing!

ADDENDUM 12:18 - The New & Noteworthy has added a few more apps and now my app is pushed out of the first page, although it's still in the list if 'See All' is clicked. Meanwhile, the visibility did apparently garnered some interest as the rank got boosted to #109 for now. Interesting...

ADDENTUM 17:38 - Hey, it's now #95. Finally broke into top 100! Pretty cool.

App selected as "New & Noteworthy"

wesley96@gmail.com (Wesley) — Tue, 10 Aug 2010 13:42:00 +0900

Thank you for noticing! (Click for larger image)

Only into its third day of sale, Apple recognized the "Korean Power Grid Info" app and put it right on top of the Business category of the Korean App Store, listing it under "New & Noteworthy" section. It's doing okay on the popularity as well (peaked at #15 on the free apps in the category, and doing #16 as of this writing), so I hope a lot more people will notice and download the app for some time to come.

Meanwhile, the app is chugging along slightly below top 100 in the Business category in the US App Store. I'm guessing a few Koreans are downloading from there, which in turn keeps the rank up. An app review and listing site called PodGate is listing the app as one of the top 100 most popular. Rank floats around #92 to #98 so far.

Chip off the old block

wesley96@gmail.com (Wesley) — Mon, 09 Aug 2010 13:34:00 +0900

Left: Me (1981), Right: Daughter (2010)

People ask whom my daughter resembles the most - me or my wife. To them I answer with this photo I took yesterday. On the left, a picture of myself when I was barely a year old is on the screen. On the right, my daughter Celine is being hugged by my wife. We look a lot alike, don't you think?

First iPhone app now in App Store!

wesley96@gmail.com (Wesley) — Sun, 08 Aug 2010 09:44:00 +0900

Korea Power Grid Info (대한민국 전력망 정보) listed in iTunes App Store

Three months of labouring has finally seen light. Apple has approved my first iPhone app and is now listed under 'Business' section of iTunes App Store worldwide. It's called "Korean Power Grid Info" - more info on WDSoft.com or App Store. Folks who want to see how much Korea as a whole spends electricity in real-time should find this app useful.

FYI, the app is released under Korean Power Exchange instead of my name or WDSoft.com because it represents the app best. All relevant data and information comes from there.

WDSoft.com gets a makeover

wesley96@gmail.com (Wesley) — Mon, 02 Aug 2010 03:03:04 +0900

WDSoft.com Logo for 2010

WDSoft.com website got a complete makeover, and moved the hosting to XiGL.net instead of a subpage in Tool-Box.info. The old pages still exist, but are not actively linked anymore. Why the change? One reason is that the old one was languishing - it has been left as it is for about five years now. But of course, if there was nothing to add, there wouldn't have been much of a reason to overhaul it. So... you know what this means. A new application is coming up! And it's for iPhone, no less.

You can head over to the Products page at the new website to check out what's new. This new app called "Korea Power Grid Info" is a result of 4 months of self-teaching and 2 1/2 months of hair-pulling development. This app should be most useful to folks in the electric industry, but general users who has an interest in conserving electricity should take a look, as well.

The app is currently in the review process at Apple, and I hope it gets approved soon.

Grandpa passes away

wesley96@gmail.com (Wesley) — Thu, 06 May 2010 14:11:48 +0900

My grandpa had become seriously weak since last year, and his health never really recovered since then. I did took two days off to visit him a couple of days ago with my wife and daughter - grandpa was barely able to open his eyes then. Little did we know that this was the last we would see him alive.

He finally passed away around 8AM today.

I'm taking a plane to Ulsan now. May he rest in peace.

KTV 한국정책방송 취재에 잡힘

wesley96@gmail.com (Wesley) — Thu, 11 Mar 2010 12:02:00 +0900

지난 3월 8일부터 10일까지 서울교육문화회관에서 '2010 범부처 녹색기술 포럼'이 열렸습니다. 팀장님과 차장님을 보좌하려 참석하였는데, 트위터로 알려드리기도 했던 내용입니다.

정부 관련 행사라 KTV 한국정책방송에서 취재를 당연히 해갔습니다. 3월8일 저녁6시에 방송이 되었는데, 친절하게 사이트에 동영상과 대본이 올라와 있습니다.
[ 정보와이드 6 관련 페이지 ]
[ 동영상만 보기 ]

방송 내용을 보니 아쉽게도 워낙 참여기술 수가 많다 보니 팀에서 진행하는 K-EMS 개발사업이 방송에 나가지도 못했고 팀장님의 장관 표창장 수여장면도 편집되었더군요. 그런데 유심히 보니 참석자 전체 화면을 담는 과정에서 저를 포함한 저희 팀 모습이 다 찍혔습니다. 1:23 ~ 1:25 사이에 나오는 화면이 이렇습니다.

1: 이효상 팀장 2: 김성구 차장 3: 정우덕 대리

화면 캡쳐에서는 너무 작게 나왔는데, 당시 행사 참석하면서 찍은 셀카와 비교해보시면 확실해집니다.

참석 인증은 된 셈인데, 회사에서 홍보효과를 인정해줄지는 미지수이군요.

Earthquake in Seoul

wesley96@gmail.com (Wesley) — Tue, 09 Feb 2010 20:21:49 +0900

It might not be much to folks living in Japan or California, but Seoul and the neighbouring area had an earthquake that a lot of people were able to clearly feel a couple of hours ago. That does not happen very often. In fact, it's the first quake I was able to feel while I was in Seoul area.

Preliminary analysis from Korea Meteorological Agency states that the magnitude was 3.0 and the epicenter was at 37.45N 126.80E, which is 8km north of Siheung, near Siheung IC of Expressway #100. That's just southwest of Seoul.

It definitely ignited a flurry of twits from all over. I hope things don't get worse than this.

Curiously, the President was out of the Blue House to visit Chuncheong province today. Maybe he knew something?

전력수요 폭등! 예비율 비상! 그 배경과 문제점

wesley96@gmail.com (Wesley) — Thu, 14 Jan 2010 11:02:16 +0900

요즘 폭설과 맹렬한 추위 때문에 전력수요가 무진장 올라간 상태입니다. 언론에서는 전력낭비가 심하다면서 절약을 종용하는 기사도 흘리고 있고요.

하지만 여러분은 전력수요 폭등에도 딱히 뭔가 전기를 쓰는데 느껴지는 게 없을 겁니다. 정전이 되는 것도 아니고 말이죠. 그건 저희 회사에서 전력수요에 따른 공급량을 정신없이 맞춰주고 있기 때문입니다.

이게 잘 되려면 '버퍼'에 해당하는 '예비율'이 있어야 하는데, 지금 그 예비율이 사상최저로 떨어진 상태입니다. 그래서 비상이라는 것입니다. 보통 10% 이하로 떨어지면 안 좋게 보는데 어제 6.1%까지 떨어졌습니다.
