创意总会有枯竭的那天,但创新不会,唯有创新才有可能源源不断、永无止境

根据网上查到的资料,创意这个词是创新的子集:创意是创造意识或创新意识的简称,亦作“剙意”。它是指对现实存在事物的理解以及认知,所衍生出的一种新的抽象思维和行为潜能。但是我认为从实践中讲,更准确地,应该这样定义创意。假设创新是一个集合$A$,那么创意就是任意一个单射$f: B\rightarrow A$且满足$f(B)\subsetneqq A$。By abuse of notation,我们直接将其记作$B$。显然,此定义推广了创意的文字定义。怎么理解这个定义呢?首先两个定义的共同之处是——创意小,创新大。在生产实践中,创意的例子比比皆是,比如说一个商品的包装、一个产品的界面和logo、相同食材的不同煮法等等。这些创意有些是有限的,而有些看似无限其实也是有其上确界。我们可以将这个说法写成一个命题。命题/定义1. 任意一个创意$B$,都存在一个最小实数$M\in\mathbb{R}_{\geq0}$使得$\|B\| \leq M$。此数被称为创意$B$的上确界,并记作$\sup(B)$。为什么说创意是有限的?从生产实践中考虑,绝大多数有创意的产品,经过激烈的商业竞争,在不断的 产生新创意 ...

Flutter、Tauri、React Native、Android原生的四次开发经历,为何最后我选择了React Native?

Flutter、Tauri、React Native都是目前移动端流行的跨平台开发框架,并且他们还能胜任全平台开发。React Native是最早开源的跨平台框架,而Flutter紧跟其后,并且Flutter最近几年超越React Native成为当前世界上最流行的跨平台框架。Tauri则是最近几年诞生的新跨平台框架,跟其他框架显著不同的一点是,它允许你使用任何前端框架,即你能够自由使用整个Web生态进行跨平台开发。Flutter、Tauri、React Native、Android原生我都尝试过,接下来我说一下我分别使用他们的开发经历。首先,我第一个使用的跨平台框架是Tauri,当时Tauri V2.0已经发布,我看它能够使用Nuxt.js或者Next.js进行开发,觉得蛮不错的。毕竟我有两个网站,一个是Nuxt写的,另一个是Next写的,这样我就只需要在原有代码基础上修改一下就行了。于是很快我就栽跟头了,首先是Nuxt的桌面端应用,我在dev模式下,没有发现任何问题,$fetch请求也能正常发送。结果build以后,发现所有的请求都废了,全是404,将url改为完整url,结果就是 ...

中国当前的教育最缺少什么?

在我看来,目前国内教育最大的问题之一,就是不告诉学生这个社会残酷的真相,只会不断给学生灌输好好读书,以后勤奋工作才能出人头地、赚钱的错误观念。这导致大学里一个非常奇怪的现象,很多人明明没有赚钱的本事,却拿着父母赚的辛苦钱无所事事,在学校享受人生,俨然一副天堂的样子。因为到了大学,好好读书这个意念也随着高考结束而逐渐淡化,没有人再管你的学习,你只需要期末考试及格,干啥都可以,甚至不及格还能补考。然而殊不知这样的学生出来以后,大概率很快会被社会毒打。被当成螺丝钉是小事,最怕的是连当螺丝钉的资格都没有。目前国内教育的目的就是为了产生好的螺丝钉。但是讽刺的是,学校即便连螺丝钉都不能好好培养出来。因为学校教育与社会现实严重脱轨,以计算机编程类的课程为例,很多课里面的内容还停留在十几年前,完全没有与时俱进,也没考虑生产实际。这也意味着,在学校哪怕你认真上好每一节,学好所有的知识,也并不能在社会的竞争中脱颖而出,你必须自学加量,疯狂内卷,在自我内耗中度过。学校只是个没有感情的流水线工厂,只会机械性的给你灌输教材的内容,不会教你如何赚钱、如何社交、如何对待感情等等更加重要的问题,最后导致很多人遇到感情 ...

是否存在人类大脑永远无法理解的数学结构?

是否存在人类大脑永远无法理解的数学结构?答案是存在也不存在。这个问题重点在于“理解”这个词,怎么样才算是理解?本文中,我们就将理解分为直观理解和抽象理解吧。所谓直观理解,指的是能够通过五官直接感受到。基于这个定义,数学从线性代数中最基础的n维线性空间开始,就不是人脑能够直观理解的了,毕竟人脑只能理解四维以下的空间,即只能理解三维的空间,不能理解处在第四维度的时间。到目前为止,四维时空是否存在都还存在争议,因为并没有直接证据表明四维时空真实存在。因此,从物理世界来看,人脑从四维线性空间开始就无法直观理解了。抛开四维空间是否真实存在的物理争议,考虑纯粹数学上的定义,四维空间是存在的。那么有可能通过作图的方式来直观理解高维空间呢?不能。那些所谓画出四维及以上空间的图,其实是通过投影等方法实现降维,将高维空间的东西通过三维的形式表现出来,并不是真正的高维空间。既然存在那么多大脑无法理解的数学结构,这时数学就派上用场了。数学正是人类用于理解人脑无法直观理解的工具,因为人脑有个很强大的功能——抽象化,既然你无法想象、也无法理解,那干脆就将它抽象化为一个数学对象来研究,即抽象理解。人类对于高维空间的 ...

数学与物理公式可以精准简洁地描述自然现象,究竟是世界本就如此巧妙,还是科学家努力简化后的结果?

这个问题有点像数学究竟是人发明的,还是人发现的?每个人基于不同理念、哲学观,会有不同的答案。而如今这个问题,可以引申出几个类似的问题。世界的底层运行规律究竟是复杂的,还是简洁的?物理定律究竟是真理,还是人类为解释宇宙而创造的?(类似于数学是否人造?)数学定理或者物理定律是绝对真理吗?或者说存在绝对真理的数学定理或者物理定律吗?这些问题都涉及到一种哲学观,没有标准答案,只是你观念的不同。回到这个问题,我是持爱因斯坦的那种观点,认为宇宙能够由简洁而优美的数学所描述,因为宇宙的底层规律本身就是足够简单的,只是人类未曾发现。换句话说,这就有点像线性空间的基底一样,只需要几条简单的定律,就可以通过线性组合,不断复杂化,最终产生如今的宇宙。这里又涉及到一个问题,即这个线性空间到底是有限维的,还是无穷维的?不过基于世界本质的简单性,从审美角度出发,我更倾向于假设这个线性空间是有限维的。因此,从这个角度看,如果数学或物理公式不够简洁和美妙,那么其本身所蕴含的奥秘也就越浅显,并且距离世界的本质就更远,即引用高斯的话“距离神更远”。故而简洁的数学或物理公式,更多的是科学家们发现的结果,是自然的,而不是刻意 ...

今天我在知乎宣传弦圈的时候,回答了一个问题有哪些数学论坛值得推荐?,结果发现有好几个回答里的数学网站已经访问不了了。这些回答里的几乎所有数学网站,我都未曾听说过(正如弦圈很多人不知道一样),这证明国内曾经也出现过很多数学论坛,有些或许曾经也辉煌过,但是最后都坚持不下去了。我做数学的时候,用的数学论坛基本上都是国外的MathStackExchange和Mathoverflow,知乎也很少用。可以说国内目前除了知乎,就没有高人气的数学论坛。毕竟本来纯数学就是一种非常小众的文化,而数学这种严肃的内容,也注定不会有高活跃、高互动的用户。因此可以看到很多国内的数学网站都已经不能访问了,有些还“活”着的,其实也是半死不活,空有用户量,但活跃度却低得可怜。而知乎的数学也早就变味了,彻底娱乐化了,真正有营养的内容已经没多少,真正有实力的大佬也相继退乎,回答都删得干干净净的。似乎中文互联网中已经没有太多数学文化的栖息之地了。国外虽然也好不到哪里去,但却跟国内天差地别,最大的MathStackExchange和Mathoverflow两个数学论坛,虽然也是不能盈利,纯粹靠捐赠维持生计,但是却能保持纯粹的数 ...

前端跨平台开发框架对比:Flutter vs Tauri vs React Native

传统移动端开发往往需要同时兼顾Android和IOS的开发,而桌面端开发又需要同时兼顾Windows、MacOS、Linux系统。如果你想要全平台覆盖,不仅意味着要同时维护多套完全不同的代码(极大提高了维护成本),并且代码和逻辑还可能不能复用,这意味着高昂的开发成本(极低开发效率),每个平台都得从零开始写。现在国内还多出个鸿蒙系统,这意味着你要同时开发和维护更多套代码,哪怕补贴钱,这成本也不是小企业能够负担得起的。于是,跨平台框架应运而生,Facebook开源的React Native,曾经是最流行的框架,不过近几年被Flutter超越。它不仅能让你使用React语言同时开发Android和IOS APP,甚至还能进行Windows桌面端开发。而谷歌开源的Flutter,是目前最流行的跨平台框架,略微领先React Native。它能让你使用dart语言开发移动端与桌面端应用。而Tauri则允许你使用任何前端框架进行全平台开发,不过也需要你懂得一些Rust语言。我们先从开发体验出发来对比这三个跨平台框架。首先,React Native能够让你完全用JSX语言来进行跨平台开发,这对于本身 ...

给Web开发者写的React Native简介,React Native与React的区别与对比(2)

本文我们继续之前的话题给Web开发者写的React Native简介,React Native与React的区别与对比(1),在上文中我们讲到在React Native想要写<p>或者<span>需要用Text组件。除了展示文本,还有一个很重要的东西就是展示图片。在React Native中你无法使用HTML的<img>,而要用React Native提供的Image组件。处理图片可以说是React Native中的一个难点,因为在React Native中无论是什么图片都需要你设置一个宽度和高度,见实例:import React from 'react'; import {Image} from 'react-native'; import {SafeAreaView, SafeAreaProvider} from 'react-native-safe-area-context'; const DisplayAnImage = () => ( <SafeAreaProvider> <SafeAreaView s ...

弦圈登录功能完成更新,之后只要登录一次便可长期保持登录

原标题:弦圈登录功能完成更新,之后只要登录一次便可长期保持登录。目前该功能仍在测试阶段不稳定,如果发现有登录后掉线问题,可以试试清空cookie。这几天,我对弦圈的登录功能进行了更新,换了目前最新的OAuth2技术,取代以前的session登录。基于OAuth2的登录功能有很多好处,首先第一个就是能够长时间的保持登录状态,现在大家上网,无论是哪个平台,你都会发现自己只要登录一次,哪怕过了很久再打开,仍然是登录状态。第二个好处就是,token是无状态的,因此会占用更少的服务器资源,这意味着弦圈负荷更小、访问更顺畅。旧登录功能基于session是有状态的,如果人多起来,服务器负荷直线上升,这或许也是之前卡的原因之一吧。由于我是第一次在Web端使用OAuth2实现登录功能,因此刚开始更新的时候,网站还是有很多bug。比如说最大的一个bug就是,关闭浏览器后重新打开,需要重新登录,这显然问题很大。而这个bug今天经过我整整一天的艰难调试,终于是修好了。别小看一个简单的登录功能,尤其是OAuth2,前后端实现真的挺复杂。最后虽然网站代码已经更新好了,但是用户浏览器里的cookie是不会因此自动删 ...

给Web开发者写的React Native简介,React Native与React的区别与对比(1)

React Native是React下的一个跨平台框架,能让你用熟悉的React JSX语法来进行跨平台开发。所谓的跨平台开发是如今的一种趋势,即用同一种语言来同时进行Web端、手机端安卓与IOS、桌面端Windows、MacOS、Linux的开发。这样不仅能极大的提高开发效率,同时大大增加了代码的可维护性,节省了大量的成本。然而React Native虽然带个React,用的也是JSX语言,却跟React有很多不一样的地方。因为React Native不仅面向网页端,还面向手机端APP,而React Native的代码会直接编译为native原生代码。在本文中,我将会列举说明几个React Native的不同之处。首先,在React Native中我们不能像React那样直接使用HTML语言,因为无论是Android还是IOS,都无法编译HTML语言。因此,我们需要使用React Native提供的组件。在React Native中,如果你想要写<div>,则需要换成<View>。View组件在Web端会被编译成<div>,而在Android和IO ...
