报名信息:由于人数限制,此次活动需要在对应的豆瓣同城活动上报名(通过点击“我要参加”按钮)。详情请大家查看活动主页。

参加上一次聚会的朋友可能已经知道了,那就是下一次的聚会就在这个周六下午,并且这次我们很荣幸的能够在豆瓣的北京办公室里来举办。想必很多豆瓣的用户都很想亲眼目睹一下豆瓣的员工是在怎样的环境里工作的。:)
这次我们也邀请到豆瓣的彭宇为我们介绍豆瓣 API,和目前的一些使用 豆瓣 API 的应用。有机会的话,我也会谈谈自己使用豆瓣 API 的一些体会。
另外,苹果的 WWDC 刚结束一周,而 iOS 4 也即将正式发布。对于开发者来说,即便没有用到 iOS 4 的新 API ,那也需要对已有的 app 进行一些更新,以更好的支持 iOS 4。同时如果需要利用新的 API,那么有些事项是需要注意的。所以针对这些问题,我也准备了一个讲座。(注: iOS 4 将于美国时间6月21号正式发布,届时就可以公开的讨论 iOS 4 的相关话题了。)
具体的日程安排:
14:00 – 15:00 《豆瓣 API 介绍》,演讲者:彭宇(豆瓣软件工程师)
15:00 – 15:30 《谈谈今年的 WWDC》,演讲者:陈犇(碰巧今年去参加了)
15:30 – 16:30 《为 iOS 4 做准备》,演讲者:陈犇

距离上次聚会已经过去很久了..北京也终于变得暖和了一些,想必大家也想出门走动走动了吧。
等待不会太久了,因为下一次的聚会时间地点已经确定:5月25日(周二)晚上在奇遇花园!
此次我们将再次邀请到来自 AdMob 的 Bernie。Bernie 去年十月作为演讲者参加过我们的聚会,那次聚会人满为患。此次 Bernie 再次来到北京,除了来为大家介绍 AdMob 的服务,更重要的是他将和他的商业伙伴一起为大家提供一个帮助做 app 的推广的方案。详细的内容,请大家期待 Bernie 的演讲。
除此之外,按照传统,我们将安排一次技术讲座。这次将邀请到 天舟 来为我们做一个关于如何用 Cappuccino 开发网络应用的演示。Cappuccino 是一套开源的用于开发网络应用的框架。它基于标准的网络技术(如 JavaScript, HTML),但实现了许多 Cocoa API,所以使用起来很类似于 Cocoa。
日程安排:
19:30 – 20:15 《如何使用 Cappuccino 和 Atlas 开发网络应用》,演讲者:天舟
20:15 – 21:00 Bernie 的演讲
21:00 – 22:00 自由聊天时间
期待大家的参与!

刚把以前的文章都恢复了,以后也还是改用中文来写文章了。如果真的被封了,也就认了。不过如果就从上次聚会到场的人数来说,我们要引起防火墙的注意还得很长一段时间
(可能有朋友还不知道,上次聚会由于到场人数太少而取消了。)
很感谢上次来参加聚会的几位朋友,真可谓铁杆了。也很抱歉聚会前太忙了,没有做好宣传工作。有了这次教训才知道其实真正从网站上直接获得聚会消息的朋友可能还是少数。另外也提醒我一件事情就是我们可能没有安排大家最想听的讲座。我注意到人数最多的两次聚会,一次是 AdMob 和 UI 设计,一次是游戏开发。我有个感觉,真正对技术感兴趣的听众其实占得比较小。这也让我有些矛盾,因为 CocoaHeads 本质上还是一个技术讲座。不过可能也有没有真正搞明白大家真正想听的技术问题。另外一个担心就是不知道只是讲座,是不是有些单调了。是不是可以加一些别的形式,具体我也没想好。
下一次的聚会至少要等春节以后了,差不多得要到三月份以后了。算算到时候搞 CocoaHeads 也快一年了。不算这次取消的,我们一共搞了七次聚会。第一次在清华的教室;第二、三次都在清华旁边的 Flow Cafe;第四、五次在奇遇花园;第六次在三里屯现代传播;第七次在 Apple Store。通过这些聚会,最可贵的是认识了不少朋友,并且看到大家在为自己不同的理想而奋斗着。
有时候在想到底是为什么要搞 CocoaHeads ,是真的为了让大家讨论技术?可能还未必能够做到。感觉每次讲座谈到的技术问题貌似引起共鸣的比较少,很难有讨论的气氛。亦或是提供一个机会让大家在一块聊聊?如果是这样,我倒觉得下次的聚会我们可以换个形式,比如大家就坐下来讨论一下27号苹果发布的新产品会对我们开发者有什么影响。
说道27号的发布会,我现在在美国,说不定到时候可以给大家在 @CocoaheadsBJ 做文字直播,大家届时可以关注下。大家对我们有什么建议都可以在这里留言,或者给 @CocoaheadsBJ 发推。
先预先祝大家新春快乐!

So starting today, I will only write in English here, because I’m concerned that someday our site will be blocked, if we continue to use Chinese. I will gradually translate all old posts into English in the future, and until then, I will hide them.
We will hold the meeting in same place where we held the gaming tech meeting at Sanlitun (NOT the Apple Store!). This time, we will have Mark Mao to give us a talk on AppleScript, and I will talk about UITableView. And at the end, we will have a big Q&A session. Which means I will invite some guys to sit on stage, and anyone in the audience can ask them any Cocoa-related (Mac & iPhone) questions.
Here is the details:
Date & Time: Jan 16th (Saturday), 14:00 – 16:45
Address: 4F, China View Building No.1, Intersection of East & North, Worker’s Stadium Road,
Chao Yang District (Two floors above the Hooters Restaurant)
Agenda:
14:00 – 14:45, Introduction to AppleScript, by Mark Mao
15:00 – 15:45, UITableView basis, by Ben Chen
16:00 – 16:45, Q&A session

跟大家抱歉一下,由于工作需要,需要离开北京几天,这周四在 Apple Store 的聚会我不能到场了。届时 Gin 同学会出面主持一下。
另外就是我在想下一次聚会的主题,目前我的想法是安排一个 Apple Script 的入门讲座,另外我可以讲讲 UITableView。还有时间就定在1月16日下午。不知道大家有啥意见?

Some friends may have already seen the post on Apple’s website that we will have our next meeting in Sanlitun Apple Store. Yes, it is true! We will have Antonio Xu from iFun Studio, and Hong Liang from orangefish to give us two talks within half-an-hour (sorry, Apple only gave us that much time).
This time, the topics will be on how to obtain the idea of a good iPhone game, and how to promote a game in App Store; we will focus much less on technologies.
I have to clarify that, due to some mis-communicating, Apple’s websites initially said I’m the co-founder of iFun Studio, and Antonio is the co-founder of orangefish… which is totally WRONG! I’m still a FileMaker employee, and have never joined any other companies, put aside co-founder. And Antonio is the co-founder of iFun, NOT orangefish. I’m sorry for any inconvenience.
Meeting Details

Date & Time:Dec 17th, 09, 19:00-19:30
