Oh, `nftables`, especially `libnftables` & `libnftables-json` are such well-designed tools with a neat API. It is very easy to use, and let me configure IP route in C++ with JSON, in plain text!

Today, I let my friend teach me about how to play the Yu-Gi-Oh! Trading Card Game. After a few times of trial and error, we finally figure out how to win against the AI. The link spell is so powerful! It shocks me, a man who have only watched about the Duel Monster bangumi.

Oh, `iptables` the syntax is daunting before reading the docs🤔

It seems that every game I have played will be a programming game in the very end.

I am tired of building large buildings by placing a lot of cobblestones repeatedly, so I end up with a /fill command.

Now, I am looking for scripting in Minecraft......

The most valuable thing I learned from life is do not care about what other people think. Why? Let me give a simple proof.

Obviously, all the other people can be divided into three groups:
lovers, haters and irrelevant. When you have done something wrong, lovers understands you. Irrelevant people even do not know about that. Haters, even you do something really awesome, they hates you all the time. So, why do you care about what other people think about you?

It is hard to learn to use a new build tools such as catkin to compile a hello-world level program for me, so I finally go back to write a simple Makefile and -I -L all the dependencies manually. It just works but works all the time!

After using evil-mode in emacs constantly, I finally found vim is good lightweight editor when editing files directly on the remote server.

I love reading about mathematics and physics, because they gave me the real insight. As I know, this world is a stochastic environment that follows the law of probability. The most important thing to do is understanding this world by gathering, analyzing and interpreting data. At that moment, I feel that I am in my own age of enlightenment.

Adding @tf.function brings a dramatic performance boost. The training time reduces from 50 episodes within 25 minutes to 500 episodes in just 15 minutes!

I wonder why they do not use a super alerting phrases to catch the document reader's attention. In my opinion, "improving performance" means at most 10% improvement, adding @tf.function or not doesn't matter. What the hell it's a 1500% performance leap......

Writing a reinforcement learning system from scratch is quite time consuming. Sometimes, if I have found some bugs, I don't know where they come from. Maybe they are from the game environment I have wrote, maybe they come from the neural network I have devised,
or maybe the algorithm is unreasonable, or maybe the reward function settings is unreasonable.

A long training time makes the agile development totally a joke,
makes the debugging process painful.

最近俺好像发现了恋爱废柴谈恋爱的一种办法:找个分布式女友呗。也就是把精神共鸣,吃什么,玩什么,看什么的自己的各个爱好分门别类,然后每一个爱好都找喜欢这个爱好的女孩聊天,分享生活。和每个女孩都不谈恋爱,完全都是朋友关系,谈也就是分享一下生活,什么情商也不需要。但是合起来就好像有了一个分布式女友似的,比非要找一个各方面都和自己很相似很契合的女孩要容易多了,恋爱的感觉好像也差不多。

愚蠢的人类啊,你们为什么要执着于谈一场集中式的恋爱呢?

没事看看stockfish,看下棋软件怎么写居然比研究怎么下棋更有趣......

找了个自动给日文网页标注Furigana的扩展,舒服了:)这样很多根据上下文一看就明白意思的汉字就不用查了,日文网页阅读难度削减

说实话,netlink这套东西不就是个基于IPC的本地服务化机制么,只是这消息格式属实忒难用了些......

A printer has been connected to the router in my office. Windows users can easily discover it, but not for me using Debian. So I used nmap to scan the localhost and found the port 9001 providing a service named `jetdirect` under 192.168.3.113. Then I used cups to set up a network printer manually for me. Bingo! That's the funniest time.

If I use Windows from the very beginning, I would have missed all of the funny things. Treated as a fool, you would be dull:)

想学读写繁体字,感觉字形比简体字好看多了......

Disabled secure boot and everything work fine:)

Japanese typing is too hard to learn. I can't type contractions easily:(

この場所は俺の新しいノートセイトがある、ようこそ!
