又了解到一个新技术(坑)ReScript
听名字，就是出来与TypeScript抗衡的，以下是网络上了解到的情况
以目前从 Github 的 star 数量来看，ReScript 还不足以撼动 TypeScript 近乎“垄断”的“统治地位”，不过随着技术的发展，鹿死谁手还不知道呢
尽管 ReScript 和 TypeScript 的出现都是为了更好地使用JavaScript，但两者还是有很大的不同，比如:
1.类型系统的实现思路就不一样，TypeScript 的目标是涵盖整个 JavaScript 功能集，而 ReScript 仅涵盖 JavaScript 的一个精选子集;
2.ReScript 代码没有 null/undefined 错误;
3.ReScript 速度非常快,它是用于 JavaScript 开发的最快的编译器和构建系统工具链之一;
4.不需要类型注释,这些类型是由语言推断出来的，并且非常正确;
5.迁移到 TypeScript 是广度优先的，而迁移到 ReScript 是深度优先的。
ReScript的编译性能远远超过TypeScript：ReScript的整个工具链都是用原生语言写的，构建系统的关键部分也是C++写的，能轻松handle一个超过100K文件的monorepo, 绝大部分项目200ms能增量编译完，而TypeScript可能在一个10K文件的monorepo就直接out of memory挂掉了。
至于怎样去选择是自己的事了，没有最好的，只有最适合自己的

Decades of psychological research show that if you have a fixed amount of time to learn something, spacing out the lessons is a much more effective strategy than grouping them." The distribution of learning over several days has a tremendous effect: experiments show that you can multiply your memory by a factor of three when you review at regular intervals, rather than trying to learn everything at once. The rule is simple, and all musicians know it: fifteen minutes of work every day of the week is better than two hours on a single day per week.
几十年的心理学研究表明如果你有固定的时间要学点东西，把课程分成不同的部分比分组效果更好。把学习任务分配到几天完成效果超级棒：实验表明当你定期复习，而不是试图一下子学会所有东西的时候，你的记忆力将达到三倍的效果。规则很简单，所有音乐家都知道这一点：一周中每天工作15分钟比一周中只有一天工作2小时效果更好。
Why is the spacing strategy so efficient? Brain imaging shows that cramming the problems into a single session decreases the brain activity they evoke, perhaps because repeated information gradually loses its novelty. Repetition also seems to create an illusion of knowledge, an overconfidence due to the presence of information in working memory: it seems available, we have it in mind, so we do not see the point of working any harder. On the other hand, spacing out the learning increases brain activity: it seems to create an effect of "desirable difficulty" by prohibiting simple storage in working memory, and thus forcing the relevant circuits to work more.
为什么间隔策略如此有效？大脑成像表明把问题塞进一个单独的课程会降低问题所激发的大脑活动，或许因为重复的信息会逐渐失去新鲜感。重复似乎还会制造知识假象，一种由于工作记忆中信息的存在而产生的过度自信：它似乎就在那里，存在我们的大脑里，所以我们看不到任何努力学习的意义。另一方面，将学习内容间隔化增加了大脑的活动：似乎通过在工作记忆中禁止简单的存储就创造了‘理想困难’的效果，就使得相关电路工作更多。

Intel has also failed to make any headway in smartphones, the most popular computers ever made. An effort in the late 1990s to build graphics chips, which have also proved handy for artificial intelligence (AI), and to which Nvidia owes its enviable valuation, petered out. Attempts to diversify into clever new sorts of programmable or memory chips—in 2015 it paid $16.7bn for Altera, which makes them—have so far not paid off in a big way.
英特尔在智能手机这一有史以来最受欢迎的计算机领域也未能取得任何进展。上世纪90年代末，英特尔公司致力于研发图形芯片，事实证明，图像芯片也有益于人工智能（AI）。英特尔逐渐放弃了研发工作，而英伟达在图形芯片上的努力使其获得了令人羡慕的估值。英特尔试图实现产品多样化，开发新型可编程芯片或内存芯片，2015年，英特尔斥资167亿美元收购制造上述芯片的阿尔特拉公司（Altera），但迄今尚未获得大的回报。
Mr Gelsinger has yet to say how he plans to deal with the challenges. He does not look like a revolutionary. He began working at Intel aged 18, before leaving in 2009 to preside over EMC, a data-storage firm, and for the past nine years heading VMware, a software firm. In an email to Intel’s staff after his appointment was announced he invoked its glory days, recalling being “mentored at the feet of Grove, Robert Noyce and Gordon Moore”, the last two being the firm’s founders. Like them but unlike his predecessor, Bob Swan, Mr Gelsinger is an engineer, who in 1989 led the design of a flagship chip.
基尔辛格还没有说明他计划如何应对这些挑战。他看起来不像一位革命者。他18岁时开始在英特尔工作，2009年离职后执掌数据存储公司易安信（EMC），过去九年来一直领导软件公司威睿（VMware）。宣布就任后，在给英特尔员工的一封电子邮件中，他提到了英特尔的辉煌岁月，回忆起自己“曾接受过格罗夫、罗伯特·诺伊斯和戈登·摩尔的指导”（后两位是英特尔的创始人）。基尔辛格与他们一样是工程师（这点与前任总裁鲍勃·斯旺不同），他在1989年领导了一款旗舰芯片的设计。
当智慧与我无益，哲学贫瘠，所有给我安慰的格言在我嘴间化为灰烬。那微小的,可爱的,安静的,爱的回忆，把我从悲伤的深井中解封，让沙漠灿若玫瑰，把我从孤独流放的痛苦中解脱，和这个世界里，伤痛，破碎，伟大的心和解。当人们懂得，不仅美丽的行为是什么样子，并且为什么这对于我来说意味很多，将会对我意味良多。他们就会意识到用什么样的精神状态来靠近我。When wisdom has been profitless to me, philosophy barren, and the proverbs and phrases of those who have sought to give me consolation as dust and ashes in my mouth, the memory of that little, lovely, silent act of love has unsealed for me all the wells of pity: made the desert blossom like a rose, and brought me out of the bitterness of lonely exile into harmony with the wounded, broken, and great heart of the world. When people are able to understand, not merely how beautiful -'s action was, but why it meant so much to me, and always will mean so much, then, perhaps, they will realise how and in what spirit they should approach me. . .

Mindful ~ Preferable
1. Mindful ~ adj. Being mindful means paying close attention to or being especially conscious of something. If you are aware of the fact that your friend is upset, you're mindful of her feelings. Sometimes mindful has the sense of "careful," as when a farmer is mindful of the amount of water she uses during a drought, or when you're mindful of the fact that your little sister easily gets her feelings hurt. In Old English, myndful meant "of good memory," or "having a good mind."
2. Preferable ~ adj. When>
An 80-year-old couple was having problems remembering things, so they decided to go to their doctor to get checked out to make sure nothing was wrong with them.
When they arrived at the doctor’s, they explained to the doctor about the problems they were having with their memory. After checking the couple out, the doctor told them that they were physically okay but might want to start writing things down and make notes to help them remember things. The couple thanked the doctor and left.
Later that night, while watching TV, the man got up from his chair and his wife asked, “Where are you going?”
He replied, “To the kitchen.”
She asked, “Will you get me a cup of ice cream?”
He replied, “Sure.”
She then asked him, “Don’t you think you should write it down so you can remember it?”
He said, “No, I can remember that.”
She then said, “Well, I would also like some strawberries>
