《吹响吧！上低音号》圣地巡礼。

在迷宫般的东京站找到了前往京都的新干线站台，下一站，京都！

完成博士答辩，等committee签完字把thesis交上去之后，成功毕业跑路。归国后旅行的第一个目的地就是阔别已久的日本，就当是久违的毕业旅行了。

圣地亚哥对我而言也算是有特殊意义的城市了，六年前在申请季步入尾声之时，从大洋彼岸飞过来参加ICCAD，误打误撞开启了Ph.D.之旅。现如今在漫长旅途接近终点之时，从伊萨卡再次重返这座城市参加ASPLOS，不禁有种“君以此始，必以此终”的宿命感。

今年三月初有幸去爱丁堡参加HPCA 2024公费旅游，因为是和PPoPP，CGO一起举办，还是蛮热闹的。虽然我除了present论文和听了几个keynotes之外大多数时间不是在宾馆补觉就是在爱丁堡的大街小巷闲逛拍照片探店，难得出趟门，还是记录一下。

最近闲来无事通关了《异度之刃2》（一周目），随手写点感想。

I have not updated my blog for a LONG time. It seems that my blog is on the edge of distinction again history repeats itself. The post Twenty Two Plus Plus in memory of my undergraduate years has been staying in the _drafts folder for nearly three months. I NEED to finish it before it is too late 24歳、学生です.

The underlying reason is quite simple another new excuse I made to justify my laziness: I was struggling with graduation last summer semester. After I arrived at Ithaca, I found a new way to keep a personal diary/journal. I had tried lots of tools, including paper textbooks, Word, DayOne, OneNote, etc., to help myself keep a personal diary since I was a little boy. None of these attempts lasted for more than two months. But for now, I have successfully kept a diary for two months. Thanks to mdbook: Create book from markdown files. Like Gitbook but implemented in Rust.

There are many tutorials and posts introducing environment setup for the prominent operating system course MIT 6.828. However, most of them do not target at macOS. Even if some of them do, they often choose to directly compile and install the related tools without using any package management technique to keep everything clean.

After searching on the Internet for quite a while, I finally found a promising solution: By creating one’s own Homebrew tap, toolchains for 6.828 could be deployed swiftly & cleanly.

To make my commits marked as “verified” on GitHub, I tried to sign them locally using GPG. It worked fine using the following command line command:

1

> git commit -S -m your commit message

But when I tried to sign commits within JetBrains IDEs, like Clion, things did not work out so easily. JetBrains IDEs do not provide native supports/integrations for GPG. So I need to make use of GPG Suite to sign commits automatically without being prompted for password from the terminal. This post records how to do so.

The original Python release of shadowsocks supports multiple users through configuration, by assigning different passwords on multiple ports.

{
    "server": "0.0.0.0",
    "port_password": {
        "8381": "foobar1",
        "8382": "foobar2",
        "8383": "foobar3",
        "8384": "foobar4"
    },
    "timeout": 300,
    "method": "aes-256-cfb"
}

Currently I am using shadowsocks-libev, which is the libev port of shadowsocks. And I also need to support the usage of multiple users.
