连续两个周末都出去飞无人机，先后购置了DJI Air 3s和Neo 2

Air 3S第一次起飞时我感到十分敬畏。联想到了第一次试骑PCX 160时的感觉。我真切地意识到这是一架飞机，我发自内心认同管控，700多g的重量从高空坠落的话很可能造成伤亡，桨叶可以割破皮肤。飞行对可靠性要求极高，这飞行器居然几千块就能买到。

Neo 2是另一种感觉。电子宠物，飞行的自拍杆。虽然已经安装了图传模块，暂时计划主要用它来自拍。电池续航短了一点，我的只能10分钟。

两架飞机都买了二手产品。很满意。

闲鱼上卖HHKB键盘，遇上一个买家直接拍下付款，收货地址是转运地址。但却不和我交流，也不回复我的消息。我提出一些疑问后，他自己选择退款。我后来发现他是台湾人，因为ptt上有同名id。由于是半夜，我感到很寂寞，就跟他说了我对他的了解，并且表示愿意再次卖给他。他很快又付款了，并且把id改成“账号没有实名认证所以不能回复消息“。啊，我终于明白他的评价是“回复快，下单爽快，收货快”了。。所谓的回复是指付款吧。

PS：本来卖掉公司用的HHKB是为了买一个Realforce R3。但再仔细了解后发现R3的Delete Esc和`键与HHKB不同，所以仍然在犹豫。

Issues when trying to migrate WordPress site to Oracle Linux:

1. iptables is replaced by nftables; 80/443 ports are blocked by default and I know nothing about nftables
2. cannot install WordPress due to various errors when using yum

At last I give up and reinstalled Ubuntu.

Jonathan Ive, who is now Senior Vice President of Industrial Design at Apple Inc., praises  Windows Phone fondly on WWDC 2013. Read quoted text below:

“…I think there is a profound and enduring beauty in simplicity, in clarity, in efficiency. True simplicity is derived from so much more than just the absence of clutter and ornamentation. It’s about bringing order to complexity. Windows Phone 7 is a clear representation of these goals. It has a whole new structure that it is coherent. and it is applied across the entire system…”
