Celebrating PopToo’s First Year

PopToo recently has become one year old!

I thank every PopToo Friend for finding this meager iOS app and using it everyday.

To a solo developer like myself, who never had his own personal project before PopToo, any kind of interest means a lot. I can’t help but feeling grateful and be humbled by all the PopToo-ings made by our Friends. Thank you so much!

Because of the experience in developing PopToo as my own personal project, I was able to prove my proficiency in software development and eventually got full-time employment.

Though I had to compromise time I may spend to improve PopToo more rapidly, having financial security freed me from the pressure to find the business model for PopToo.

So, I could keep PopToo as a free app without advertisements. By treating it as a non-commercial project, I didn’t have to ask for the user’s attention for the ads, but just for their satisfaction in using PopToo everyday.

About 3 months after PopToo’s release, an awesome app called Soundtracking was introduced. Other than its name, the app and its service were exactly how PopToo dreamed to be. Instead of feeling beaten, it taught me about the importance of knowing the limits of PopToo project. Without serious capital and additional development resources, trying to make PopToo as good as Soundtracking while having full-time job could have been the fatal disaster. It did solidify PopToo’s mission to stay non-commercial project, to be used for training me to become better iOS developer and for building meaningful relationships with PopToo Friends.

The future of PopToo is about becoming the Real Service. Though I’m not sure about keeping it non-commercial, I want to build great community of people who love to use PopToo. Three of the important objectives for continuing PopToo project are upgrading to have aesthetically pleasing user experience, building the web platform and utilizing geolocation more effectively. For these objectives, I guess I should learn more about graphic design and web development.

Again, I would like to thank all my PopToo Friends. Thank you so much for enjoying your favorite music with PopToo!

iOS Tech Talk 2011 in Seoul

[This blog does not contain any technical information. Also, I am an Apple fan, probably my blog will be purely subjective.]

iOS Tech Talk World Tour

Today, December 8, was very special day for me.

It was my birthday, which was meaningful to me and my parents.

Also, it was the event day for iOS Tech Talk in Seoul, which was meaningful to every iOS developer in S. Korea.

One of the greatest things I didn’t expect from this event was to be able to meet the same instructors who were at the WWDC. In other words, this Tech Talk event can be considered as the extension of WWDC, not the another kind.

To some people, including myself, these instructors are the Rock Stars. They were touring around the world to excite their fans. Some people took pictures with their stars. I didn’t do it because I thought it could be perceived as objectifying them, which could be impolite. However, I just hope I don’t regret not taking pictures with them, later.

Aside their professional authority in the field of software development, the instructors were extremely friendly. They were so generous enough to pay good attention to people they never met before, who kept asking annoying questions. Probably, it’s their job requirement as the  Apple Evangelists. However, it’s impossible to ignore but respect their effort.

This one day event did impress me a lot, strengthening my positive perception about Apple and its people. They do know how to make their fans happy.

Allow me to reuse the tweet I shared: With these enthusiastic, friendly and yet extremely professional masters, the future of Apple will stay to be bright, I think. Even if Steve is no longer with them, with us.

I definitely want to attend WWDC 2012. Not only because I am eager to learn new technologies, but also I want to continue the joyful conversation I was having with the masters. Now it’s clear to me that, everything about Apple has become very personal to me.

[Korean] About my comment on the book, ‘Real iOS Programming without Interface Builder’

This is the comment I left at following URL: http://www.acornpub.co.kr/blog/406  ‘인터페이스 빌더 없이 하는 아이폰 리얼 프로그래밍’

It’s about questioning the intention of the book about doing iOS development WITHOUT using  Interface Builder. It’s written without reading the book yet.

I’m a strong proponent of Interface Builder and its usefulness, and my comment was about that not using the Interface Builder may not be useful for those who need to read this book, who may be new to programming. And ironically to the author’s intention, it may not be able to help creating the application which should be easily maintained and expanded.

(내용을 읽지 않고, 별도의 프로그래밍 관련 주제의 댓글입니다. 소개글만 읽고 적은 것이므로. 책에 대한 평가로 오해하지 말아주세요.)

좋은 책이 나온 것 같습니다. 인터페이스 빌더’만’ 쓸 줄 아시는 분들에게 무척이나 유용하고 의미있는 내용을 가지고 있을 것이라 생각됩니다.

정교하고 디테일한, 100% 통제를 해서 모든 요소들을 일일이 다 챙기는 것이 중요한 프로젝트라면 당연히 코딩으로 VIEW 또한 손수 다 그리는 것이 좋을 수 있습니다.
또한, .xib 은 일종의 XML 로서 parsing 과정을 거쳐야 하기 때문에, 0.001 초라도 아껴야하는 경우에는 분명 사용하지 않는 것이 맞습니다.

하지만, MVC 분리법에 대한 충분한 이해가 되지 않은 초보 개발자, 실제로 응용해본 경험이 적고, 그 가치를 제대로 이해하지 못한 개발자들에게는 잘못하면, VIEW-CONTROL-MODEL 에 속하는 코드들이 우후죽순 막 섞히는 결과물을 내게 만들기도 합니다. 마감날짜가 급한 경우에는 더더욱 유지보수에 문제가 있는 (앞으로 문제가 생길) ‘위험한 코드’를 만들게 되지요.

이렇게 되면 소개글에 나타난 대로 유지보수에 탁월한 해결책이 되어주지 못하게 됩니다.

분명 하드코딩은 중요하고, 어떤 개발환경도 반드시 이것을 가능케 해야 합니다. 하지만, 이것은 과거의 생산물이 가진 생명력을 연장하는데 좋은 것이지, 미래를 위한 혁신적인 결과물을 만드는데 장애가 되는 것이라 생각합니다.

그래서, 혹시라도 미래를 위해서 일해야할 초보 개발자들에게 잘못된 습관을 가지게 하거나 자칫 혼란을 주지 않을까 하네요. 컴퓨터가 할 수 있고, 컴퓨터가 해주는 것이 훨씬 더 좋은 일인데도 불구하고, 단지 자기는 이렇게 가르침 받았고, 이렇게 하고 싶다는 이유만으로 하드 코딩을 고집하는 것은 미래에 대한 좋은 준비자세가 아니라고 생각합니다.

또한 단지 코멘트를 많이 남기기 위해서도 좋은 이유라고 생각되지 않네요. 코멘트 대신에 코드 그 자체로 모든 내용을 표현할 수 있다면 제일 좋다고 많은 분들이 얘기하시는 것 같던데.

반대로, 인터페이스 빌더를 쓰면 그에 대한 설명을 구구절절 코멘트로 어딘가게 남겨둬야 하니, 아예 코멘트 없이 코딩을 하기 위해서라도 하드코딩을 하는게 좋다고 하려 하신 거라면, 적극 동감할 수는 있습니다.

책의 내용은 분명 추정컨데 회사내 베테랑 개발자들에게 무척이나 도움이 되겠지만, 책없이 공부할 줄 아시는 그분들에게 정작 책이 필요하지 않을 것도 같고요. 왜 그동안 이것을 공개적으로 다룬 책이 씌여지지 않았을 지 좀더 냉정한 고민을 하셨기를 바랍니다.

당연히 그런 고민을 하셨다면, 어떻게 하면, 인터페이스 빌더의 장점과 하드코딩의 장점을 융합해서 양쪽 모두가 가진 탁월함을 같이 쓸 수 있는 방법도 책에 써주셨을 거라 믿습니다.

이런 목적으로 두마리 토끼를 다 잡는데 유용한 내용을 쓰셨다면, 이런 책이 다른 곳도 아닌 한국에서 한글로 먼저 출간된 것에 엄청난 자부심을 느끼셔도 좋을 것 같습니다.

My understanding in naming a Class with Prefix

Many source codes, especially those which are written in kinds of C languages, almost always named their classes using prefix.

Intuitively, I adopted to use this way of naming, since many GOOD ones were written in this way. My usual way of learning is by imitating.

As I’ve gained more experience, it became obvious to me why it’s critically helpful for programming.

In my case, I care quite a lot how methods and variables are named. Nicely named ones can help understanding the workflow, minimizing any confusion, thus producing reliable lines of codes.

However, one must careful not to use same syntax for the name of class and instance of it, since it’s difficult to distinguish if one is meant for the instance or the class. It gets worse if the class name and the instance name are as common as something like ‘WebViewController.’

Since naming instances of class happens more often than naming a class, it’s better to name the class with less common way. To make it less common, one of the easiest way is to use a prefix, elongating it to be syntactically different. For example, by using prefixed, ‘FXDWebViewController’ for the class name, one can use ‘webViewController’ as a name for an instance.

Though this instance name is quite common, you can use it as often as possible, without causing the programmer to be confused and even preventing compile time or run-time errors, as long as they are separated by scopes.

It gets even better when one has to use Find and Replace function, since syntactically different words are much easier to be found more quickly.

Also, using the prefix, you can leave it as some kind of signature, claiming your authorship and responsibility on the source codes.
