**I have a job now!**
I'm a Chinese shitizen, but I generally don't post in Chinese to avoid being suffering from other Chinese.
I'm physically a male, but I don't care how people think about my gender. I can be male, or female, or cat. But if you ask, I'd prefer to be referred to as male. Also, I support LGBT+ people, and I'm a copyleft. I don't think I'm too aggressive in arguing things, but sometimes I do. You should handle it with care.
I post about programming (most time is Java and Kotlin, unless I have a new love), and some random things I find interesting. I also post about my mental health, which is in a stable state of instability, thanks to my parents and Chinese society.
Anyway, if you want to follow me, I'm glad to see you. And, have a nice day.

I suggest we set up a specific instance for Twitter people, so we can block them based on instance, LOL.

当我读《资治通鉴》的时候，就反复被灌输一个理念：国家要大一统不要分裂，国君要英明不要昏庸。这个理念是中国人现在还深深认可的。
我们确实发现一个问题，那就是当一个朝代结束的时候就是乱世，非常痛苦。所以我们就觉得，哎呀不好，我们必须要避免这种情况，要一直维持盛世，要守正，要有美德。
这是一个困扰了我几十年的一个陷阱。我们看到事实是，中国永远在盛世——乱世——盛世——乱世，不断循环。你有没有发现哪里不对？
问题就出在，不是说盛世有多好，乱世有多不好（盛世其实也不是多好，只不过是坐稳了奴隶的时代，这且不表），而是盛世和乱世就是这个系统的标配。你必须两样都得有。这就像自行车，一个前轮，一个后轮。甚至你可以说：乱世之所以存在，就是因为盛世的存在！这其实就是“圣人不死，大盗不止”。
乱世是从哪里来的？当然是从盛世那里来的。乱世之前就是盛世。那么盛世为什么会生出一个乱世呢？我们可以说，盛世埋藏了乱世的种子。那么这个种子是什么？其实就是这个系统的不稳定性。也就是说，这个系统在比较理想的情况下，它可以出现盛世，但情况是在一直变化的，而这个系统本身并没有一个有效的纠错机制。当情况出现变化的时候，乱世就不可避免地出现了。一个系统偶尔能工作，但冷不丁就坏，这当然是一个严重的设计缺陷。
那么《资治通鉴》就说，我们要发挥我们的主观能动性，用道德来让它不坏。这个想法当然很美好，但系统的运行不是依赖于最坚固的那个零件，而是依赖于最脆弱的那个零件。只要最脆弱的那个零件坏了，系统就坏了。所以主观能动性能起到的效果有限。就好像你一直盯着一个东西它就没事，这是你的主观能动性，但你闭一会儿眼就出事了，那就是主观能动性的局限性。
所以你必须有一个机制来自动对系统进行纠错。一旦问题出现，它会自己跳出来，这就可靠多了。一个纠错机制不行，那就两个。这就是三权分立，民众监督。这样当然不是说就永远不会出错，但不管是从逻辑上还是从实际的经验上，这样就是能够少出错。
我希望更多人明白这个简单的道理。

In case you want to know why this filesystem requires a such amount of RAM:
Because it's JAVA.
A fully working read-only FUSE, backed by my own MerkleDAG structure, namely the https://github.com/hurui200320/Ariteg
By caching everything in RAM and using 2.8GB RAM at the start-up, then growing to 5.5GB when playing 12 videos at the same time (bottlenecked by the GPU's video decoder), the filesystem itself is working pretty well. The random reading is fairly good, too: sliding through the progress bar in MPV results in an almost instant response (data stored on an NVME SSD).
I would call it a day.
Also, 295GB of video files only occupied 290GB after block-level deduplication. I would argue that compressing the same data would require an infinite amount of time (my program can handle more than 50MB/s when reading and writing happen on the same disk, while 7z can only get 20MB/s) and wouldn't get a better compression ratio than this.
hmmmmm, Chinese piracy vscode.

Video: A Toyota pickup truck slowly pulled the shuttle across the bridge.
Me: That must be a modified pickup truck.
Wikipedia: The journey was famous for an *unmodified* Toyota Tundra pickup truck pulling the Space Shuttle across the Manchester Boulevard Bridge.
Me: WTF? 78 tons of spaceship, unmodified truck?

The raspberry pi rebuild version is amazing.
The original version would be fantastic in terms of engineering.

I'm not sure if it's Mayday or not (maybe Mythbusters?), but from some TV program, I learned that modern airplanes are designed to be able to land safely by a passenger with autopilot and instructions from the tower.
The engineering is amazing.

Q: Why did the IRS decide to investigate a software company that makes command interpreters?
A: It's a shell company.
Just watched the first video, amazed by the technique used in the vid.
Also reminded me of the second video, which is also pretty amazing.

Copyright is not always a good thing. Of course, I don't want people to abuse my content, and I want to control them. But when your contents have some value to preserve, copyright is just a bunch of shit.
Especially when the owner doesn't care. I mean, Nintendo, closing the 3DS eshop and don't care about those old games.

And it is another normal evening, where splatoon3 still failed to make connections, exactly when I was in a perfect mood for some online gaming.
Good job, Nintendo.
And for others, Good night from UTC+8.
