What was the Problem? :() When playing with my RP2040, following the official SDK instructions, I wonder why I have to type cmake then do make, why does it take two steps to build my project? Well, long story short: Cmake is a cross-platform Makefiles generator, while make “reads the makefile and invokes a compiler, linker, and possibly other programs to make an executable file...
Intro I’ve been pretty into the Raspberry Pi Pico family lately—it looks nice, and it’s new, there is a fast-growing community there, and it would be cool to play together. Pico W is the newer member with the…well, you guess…the Wireless capability. I thought it would be nice to set up some code to allow me to send data from the terminal to the Pico through wifi...
Lately, I was into the studying process of machine learning, and outputting(taking notes) is a vital step of it. Here, I am using Andrew Ng’s Stanford Machine Learning course in Coursera with the language of MATLAB. So the rest of the code I will write in this post by default are based on MATLAB. What is ML? “A computer program is said to learn from experience E with respect to some...

What？ 随着Minecraft的多年发展与版本迭代，现在终于可以分为三大派： 1.基岩版（XBOX，WIN10 UWP， 手机） 2.JAVA版（也就是之前电脑上玩的那种） 3.网易版（辣鸡） 基岩版（BedRock)是从PE手机版脱出的版本，以前的版本总是和JAVA版大步脱节，可现在已经平头齐步走了。个人非常看好BR版，因为其平台整合的很不错，各个设备都可以玩，不论是个人联机还是教育应用都很有优势，未来开发者社区会倾倒更多资源。 Why？ 这里可能有人要问了，既然已经有了领域了，为什么还有自己开基岩版服务器？ 首先，领域服延迟高，其次，对多人支持不是很好，最高也就10个人，也不便宜。 最后客制化程度也很低。 How？ 这里可爱的开发者团队已经开发出了基岩版服务器包（Alpha）所以只要按照我这里的步骤一步步来，在5分钟内就能配置好属于你的基岩版Minecraft服务器...
Rookie speech 🙂 When a little young baby just born, learning occur at every moment the person lives on the earth, study let people become completed, also helps them to live in this society. One’s future is to decide by learning. Teachers teach students? Right? But how many of these relationships could be in a highly efficient way? When you in school, how many times you see there are some students...
It’s just a funny and chill little project, but I still believe no one did such research before 🙂
暗网，隐网，深网，听着很吓人，是吧。在媒体的推波助澜下，这些东西的确变得神秘而又不可触碰起来。但是，说实话，有什么难的呢，难道每个暗网用户都是计算机高手不成？ 什么是暗网？ 这里有点区别，倒不如这么说吧，无法直接由搜索引擎搜索到的页面都属于隐网，也就是The Hidden Web。 媒体搞了一个冰山理论，什么绝大多数的网络都是罪犯的天堂，也是可笑之极， 那我知乎的个人编辑页面也成为犯罪天堂咯？这里所要澄清的是，隐网的确很多，但是我们即将要讨论的暗网却并非如此。 暗网， 数量在几万左右，不时关闭，不时开启，有违法色情，毒品与枪支的交易，当然还有FBI的钓鱼网站。这也是大家所熟知的。如果要深入了解下具体，可以看看这篇文章：出于好奇，我去暗网里瞧了瞧 —— 你就别去了 暗网网站的网址一般都如此：，而这是无法用普通的浏览器访问的，而是一个加密浏览器，也就是我们的Tor。 如何使用Tor...
Since I moving my telescope to my school for my Astronomy Club, I put it for a long time because my club is still weak and no one in the club could be seem as a real club number. But I set up a small observation recently with another guy who are not in my club, and I took 16 photos of moon by my lovely A7RIII, however, the truth prove that it is useless to stack 16 photos, but I think it is a...
前言： 我不信任像百度云，dropbox什么的公有云，并不是说怕资料外泄什么的，主要是不想让数据流落在外（不然多可怜啊）：）我常常需要大文件的快速转运，也不想把钱花在那些花花绿绿的功能上，我就想要一个干净高效的私有云。 VPS： 我的第一个想法是搭建一个在VPS上的owncloud，想想上次在vultr上搭vpn懒得停，欠了他26.78刀，不想还了，就用我第二个邮箱建了一个账号—然后发现我第二个邮箱也被我注册了一些奇奇怪怪的东西—又试了几个，发现我7个邮箱全都用来注册了，哎，算了那还是还他钱吧，毕竟用的主邮箱注册的。 三下五除二搞定，测试主机速度，ping主机，销毁重建被墙的ip然后发现还是洛杉矶机房最快，也没多快啊！！！现在vps就没有便宜的净土了，一开始还好，能到1/2的速度，然后就开始以kb/s为单位。不行，太不稳了，实在受不了，就想起自己买个nas。...
