** I wrote some APL at work and I like historical fiction **
This summer my oldest kid — 8 years old — asked to learn more about programming. They’ve already got about a full time job’s worth of experience with Minecraft’s red stone, Super Mario Maker 2, Logo, and Scratch so I knew we weren’t starting from nil, but, despite having done a bit of teaching about programming with kids in the past, I hemmed and hawed. After hemming and hawing for a bit, though, I realized that I was hemming and hawing abou … ⌘ Read more

奥运乒乓球决赛，为什么莫雷加德的衣服干爽而樊振东却大汗满身？
作为一名纺织品化学工程师，我就从纺织材料这个角度来和大家好好聊聊这个问题。
全篇干货没废话，先说下我个人的3个结论
1）衣服看起来出汗明显≠速干效果差，反而可能更好
2）日标的速干衣标准更适合剧烈运动出汗场景
3）樊振东是真的爱出汗体质
一：速干衣为什么比常规的衣服更加容易干燥？很多消费者都会吐槽涤纶、尼龙这类化学纤维做的衣服穿起来闷热不透气，但实际上恰恰相反，涤纶、尼龙是运动速干衣的主流材料
在问题开始前，有个核心知识点一定要给大家讲清楚，那就是大众所说的“面料透气”是个非常复杂指标，不是面料孔隙多穿上去透气（直接测试透气性其实是防风指标）。
穿着透气不闷汗的本质， 其实是让面料尽可能的吸收皮肤上的汗水，只要皮肤表面干爽你就会觉得穿着透气我们日常觉得棉T吸汗透气，是因为棉花的公定回潮率有8.5%（100g棉花能吸收空气中8.5g的水蒸气），你可以简单的理解成“饼干受潮变软”的这个过程。

Here I am with my daughter on the new bike :)

@bender@twtxt.net It cost what you mentioned here too, but they had a special discount, and the shop gave 20% discount for all the gear we needed (since I bought the bike + gear for two persons), so all in all I got a really good deal on it. Also interest rate is locked for 3 years (low rate) so that was also a good deal.
I just took the longest time I could on the loan, to have a low price each month, and then i just pay extra whenever I can to get it payed down faster.
Luckily the Marlyn, my son, and my daughter all fit the same gear, so the 3 of them share that, that saved a lot of money too :)
When i met Marlyn (before we had kids) I asked here to go on her first trip with me (I had a bike before I met her back then), and we went on a 2 week ride from Norway to Italy and back (venice) through the alps and all that. Was super fun, and I think it’s pretty cool of her to say yes to a 2 week trip as passenger :)

历代的《三国志》里有哪些细思恐极的细节？
看了一圈没有说三国志12的，三国志12人气这么低吗？补充几句。
1. 高览在本作是单挑王，战法一开无人能制，不愧是“河北四庭柱”之一。如此看来，设计组应该研究过张国良的《评话三国》 。
(高览武力82，战法降敌方30点武力，也就是说武力112才能打平，可吕布+方天画戟才108，可以想象武力七八十的碰到高览该有多绝望。）
2. 作为吉祥物，刘禅能力值全班倒数第一，看起来这辈子就基本告别战场了。但问题是，他的战法是“全攻城强化”。本作有个设定：系统非常青睐拥有攻城类战法的武将，不但让他们出征，而且是第一顺位。由此，吉祥物摇身一变成为战争狂魔，动辄带着四五千士兵敲人城门。这一点与文明系列的“核平使者甘地”有异曲同工之处，不知道是不是光荣有意为之。说好的“乐不思 … ⌘ Read more
