Dec 05, 2019 from Max Brenner Minikube vs. kind vs. k3s - What should I use? These days there are a few tools that claim to (partially) replace a fully fledged Kubernetes cluster. Using them allows e.g. every developer to have their own local cluster instance running to pla...
Nov 14, 2019 from Remains of the Day Smoke and Mirrors “When a judge walks into the room, and everybody stands up, you’re not standing up to that guy, you’re standing up to the robe that he’s wearing and the role that he’s going to play. What makes him...
Nov 13, 2019 from Remains of the Day Status Update, and How Everyone IPO'd in the 21st Century Sorry for the long hiatus. I've been doing some formal advisory work and a bit of angel investing these past months, and so more of my writing has been private.More than that, though, the Internet,...
Oct 31, 2019 from Renfei Mao on flujoo 自学成牛的作曲家 阿诺德·勋伯格(Arnold Schoenberg),可以说是现代音乐的开山鼻祖,一位历史级、世界级的作曲家。但你可知道他基本是靠自学的?本文将谈谈他的这部分经历。 他有多牛? 什么样的作曲家称得上牛逼?可能得满足以下条件: 作曲技术精湛,创作了一些高质量的作品,这些作品被世界级的演奏家、乐团演奏。 有自己的一套作曲技法,这套技法对其他作曲家或音乐的发展有一定影响。 音乐史书上会提到 TA,...
Sep 12, 2019 from Coding Horror The Rise of the Electric Scooter In an electric car, the (enormous) battery is a major part of the price. If electric car prices are decreasing, battery costs must be decreasing, because it’s not like the cost of fabricating rubbe...
Aug 20, 2019 from Coding Horror Electric Geek Transportation Systems I’ve never thought of myself as a “car person.” The last new car I bought (and in fact, now that I think about it, the first new car I ever bought) was the quirky 1998 Ford Contour SVT. Since then,...

Jun 15, 2019 from Renfei Mao on flujoo 不爽,但有效的学习方法 本文要介绍一类学习方法,一方面,它们能让你记忆更持久,学习效果更好,有大量研究支持;但另一方面,它们使用起来会让你不太爽,所以通常不是人们下意识的选择。这类方法下面有很多个变种,表现形式不同,但核心相似。我们先通过下面的实验来认识其中一种。 背单词实验 这项实验发表于 1979 年,实验流程简化一下是这样的:1 科学家找到了你,你的朋友天天和月月一起来背单词。 单词以「中文-英文」这样的形式...
Jun 02, 2019 from Renfei Mao on flujoo 学习时要避免犯错吗? 错误这种东西通常以反面形象出现,难让人喜欢。人们谈到学习中的错误时,也往往是说,要避免错误,或是改正错误。这里透露的信息是,错误是不好的,最好能从学习中去掉。错误这么不受待见,可能有两方面的原因: 第一,错误对学习效果有消极的影响。比如学钢琴时,你要是养成了错误的弹琴手势,演奏效果就会受影响。而且之后要改也会很麻烦,得花去不必要的时间精力。所以不如一开始就小心翼翼,避免犯错。 第二,错误给人...
May 30, 2019 from Coding Horror An Exercise Program for the Fat Web When I wrote about App-pocalypse Now in 2014, I implied the future still belonged to the web. And it does. But it’s also true that the web has changed a lot in the last 10 years, much less the last...

Apr 26, 2019 from Renfei Mao on flujoo 什么是智力测验? 智力测验 人们用尺子量身高,用智力测验「量」智力。智力测验就是用来量你有多少智力的尺子。 智力不像身高,看不见摸不着,怎么量呢? 思路和考试很像:心理学家会先设计一些题目让你做,这些题目会用到你的智力。你智力越高,题目做得就越好,得分就会越高。心理学家最后就根据你的分数来推断你的智力水平。 我们直接看具体的例子。 韦氏智力测验(Wechsler Intelligence Scale)是目前最...
Apr 08, 2019 from Renfei Mao on flujoo 儿童情商培训靠谱吗? 靠谱。 靠谱体现在四个方面: 科学理论 科学证据 课程体系 行业规范 本文围绕这四个方面展开。 情商是什么? 大众口中的情商在心理学里称为社会-情绪智力,英文是 social-emotional intelligence,它包括五个方面(Collaborative for Academic, Social, and Emotional Learning, 2003): 了解自己:了解自己的想...
Mar 25, 2019 from Renfei Mao on flujoo 什么是科学的课程设计? 在教育行业,说一个东西是「科学的」往往是很高的评价。家长希望孩子上的培训课是科学的,培训机构也喜欢用科学来标榜自己。 那怎么样的课程是真正科学的?这篇文章从课程效果评估的角度来谈这个问题。 从课程效果说起 课程有没有效果,有什么效果,这些是家长非常关心的问题。 有的课程,效果评估起来比较简单,凭借直觉就可以判断。比如你上了减肥课,结果发现自己无情地胖了,那么你可以愤怒地说,这个课没效果!比如...
Mar 22, 2019 from Renfei Mao on flujoo 记忆训练有用吗? 简单地说,有用。 但是记忆训练或者记忆策略并不只有单一的一种,本文将要探讨三类,这三类记忆训练侧重点并不相同: 第一类让你记得更「快」。 第二类让你记得更「多」。 第三类让你记得更「久」。 而这三类记忆训练的效果也各不相同: 第一类暂时缺乏有力的证据证明其有用。 第二类有用,但是效果的范围有限。 第三类有用,但是效果的程度有限。 第一类记忆训练:记得更快 简单粗暴地打个比方:记住东西的过程就...
Mar 14, 2019 from Renfei Mao on flujoo 要不要奖励孩子? 奖励在教育中非常普遍。孩子考试得高分,父母买玩具作为奖励。父母这么做通常是希望通过奖励来进一步激励孩子的学习热情。 但你可能也听过这么一种观点,奖励不但没法激励学习热情,反而可能损害。奖励会让孩子觉得学习就是为了获得奖励。久而久之,孩子会失去对学习本身的喜爱。 哪种观点是对的?心理学对此有过深入的探讨,颇为曲折。我们来看一看。 核心概念:内部动机 批判奖励的观点认为,奖励会损害孩子的学习热情...
