33 - 我游戏创业失败的教训 - game-startup-lessons.txt

记得2014年的时候，我在一家北欧公司CCP做着次时代PS3/PC相关的游戏引擎研发，我们引擎组的老大是来自英国的一位大牛，曾经是GTA的一位引擎leader。CCP当时在研发氛围，还是福利等方面在行业中绝对是数一数二的，另外技术实力也非常厉害，我们当时把UE3的渲染框架和算法改了个底朝天，就是为了适应我们当时的一款游戏：EVE-Dust514。

那时候外企的经验还是非常吃香的，不像现在，随着外企的陆续关门，外企的背景跟国内大厂的相比还是占弱势。但是，无论现实有多好，还是拗不过年轻的冲动，看到14年手游市场的逐渐火爆，我跟朋友几次碰面后，毅然决然决定离职创业。

我们合伙人共有4位，美术是CCP的，另外两位是来自腾讯：一位策划，一位服务端，我是作为客户端和引擎加入，对于前期的研发，这个配置还是比较豪华的。但是我们当时4人并不是互相都认识，我认识美术，美术认识策划，策划认识服务端，大家互相不熟悉，所以这也是对后面的发展有一定的副作用。

34 - 苹果暂免脸书在线产品30%分成 - apple-facebook.txt

美东时间25日，Facebook表示，苹果已经同意，除游戏创作者外，允许因为新冠肺炎疫情被迫通过Facebook App在线上开展付费活动的小企业，无需支付30%的苹果App Store交易收入抽成，对这种苹果税的豁免期为三个月，即到今年年底，2021年将重新开始征收。

　　这意味着，对那些利用Facebook Pay系统处理支付的小企业来说，直到今年末，他们都不用将自家iPhone App获得的部分收入交给苹果。

　　苹果此后确认，共享租房平台Airbnb和健身课程订购平台ClassPass也得到了Facebook这样的豁免。

35 - 美国法官暂停美商务部WeChat下架命令 - suspent-wechat-ban.txt

据《华尔街日报》等多家媒体报道，加州联邦法官劳雷尔·比勒20日下达命令，要求发出初步禁令，以阻止美国商务部禁止下载WeChat的行政命令于20日23时59分生效。商务部18日发布的行政令禁止20日后在美国境内与WeChat有关的交易。《纽约时报》称，鉴于该法官的裁决，相关禁令在20日晚不会生效。

　　另据CNBC报道，美国加州地方法官比勒（Laurel Beeler）20日在一份命令中称，提起诉讼的WeChat用户“对第一修正案的价值提出了严重质疑，权衡利害后，倾向原告一方”。报道称，比勒的初步禁令阻止了美国商务部的禁令，美国商务部对此没有立即置评，而WeChat用户联盟则称赞该裁决是“美国WeChat用户的一项重要而艰辛的胜利”。

　　美联社称，比勒法官的裁决是应一组微信用户的请求下达的。比勒法官认为，美政府的行动将影响用户的第一修正案权利，针对WeChat的禁令抹杀了他们的交流平台。该法官还认为，美政府有关微信构成“国家安全威胁”的具体证据也“很不突出”。

36 - 苹果公司进入“技术性熊市” - apple.txt.txt

苹果公司进入“技术性熊市”
　　苹果在短短12个交易日内，已从高点回调超22%，跌入技术性熊市。市值蒸发5333亿美金左右，约合3.6万亿人民币。苹果公司宣布1：4拆股后股价在8月份大幅飙升，成为首家市值突破2万亿美元的美国公司。此后该公司股价一路下滑，而最新秋季发布会上5G新款iPhone的缺席也令市场大失所望。

　　在过去几周中，苹果公司股价的疲软也正值科技股遭到广泛抛售，纳斯达克综合指数已跌入修正区域，较历史高点下跌了10%以上。一些投资者认为，对科技巨头的抛售来自对过高过快增长的高估值的担忧。

9月14日消息，据微软官方和涉及Tiktok出售资产谈判的知情人士称，Tiktok的母公司字节跳动已拒绝了微软收购Tiktok美国业务的要约。

　　微软被认为是从字节跳动手中收购TikTok美国业务的最有钱的美国科技公司。此举使甲骨文成为TikTok唯一公开的剩余竞购者。

　　甲骨文是少数几家公开与美国总统特朗普结盟的硅谷公司之一。参与谈判的人士称，字节跳动已表示，甲骨文将成为其“技术合作伙伴”，但尚不清楚这是否意味着它也将获得该应用的多数股权。
