前些天一直在找便宜的云服务器，偶然间发现一免费的云平台，这里推荐给大家。

就是阿贝云，网站是https://www.abeiyun.com

说一下感受

1、阿贝云虽然是一小众的云平台，重在免费，该有的东西都有，还能免备案这是最舒服的。

2、使用了一天，上了项目，网速不慢。

3、唯一要指出来就是磁盘太小。

  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install libssl-dev
      # On Arch Linux
      sudo pacman -S openssl
      # On Fedora
      sudo dnf install openssl-devel

  See rust-openssl README for more information:

      https://github.com/sfackler/rust-openssl#linux

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

经过检查openssl与rust均为最新版本, 

```bash

在网上找了一下, 查到资料, 在[rust-openssl的issues](https://github.com/sfackler/rust-openssl/issues/1227)中提到类似报错, 得到解释如下:

> If you are cross compiling to MUSL, you either need to point openssl-sys to the location that you have a copy of OpenSSL cross compiled to MUSL, or tell it to build a copy of OpenSSL itself with the vendored feature.
>
>	如果你是交叉编译到MUSL，你需要将openssl-sys指向你有一个交叉编译到MUSL的OpenSSL副本的位置，或者告诉它用vendored特性构建一个OpenSSL本身的副本。

由于不会rust, 依靠关键词"交叉编译"+"cargo"搜索到了[cargo交叉编译rust程序](https://blog.csdn.net/tyc880616/article/details/104371502), 顺着找到文件:

```
[root_cn@archlinux .cargo]$ cat ~/.cargo/config
[source.crates-io]
replace-with = 'sjtu' # 指定使用下面哪个源，修改为source.后面的内容即可

# 中国科学技术大学
[source.ustc]
registry = "https://mirrors.ustc.edu.cn/crates.io-index"

# 上海交通大学
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index/"

# 清华大学
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"

# rustcc社区
[source.rustcc]
registry = "https://code.aliyun.com/rustcc/crates.io-index.git"
```

没有找到交叉编译的设置, 由于本人不会rust, 线索断了, 尝试向大家寻求一波帮助, 非常感谢阅读.

【轉貼】ASP.NET Core Developer Roadmap in 2024

> 前段时间看到了站长发布的[帖子](https://hackertalk.net/posts/363299262696828928)提到了`latexify`这个库，最近有点兴趣研究了一下，写下此文作学习笔记吧

首先留一个官方[github](https://github.com/odashi/latexify_py)，官方提供了一个`ipynb`存储的示例，考虑到翻墙不易这里就留一个那份文件的[备份](https://github.com/Expector-Hutch/demo/blob/main/latexify_example.ipynb)吧。

# 现在进入正题

安装很简单了，这里直接用`pip`，需要注意的是`latexify`库并不支持最新的`python`版本：

```bash
$ pip install latexify-py
```

官方文档介绍了三种使用方法，分别是`latexify.function`，`latexify.expression`和`latexify.get_latex`；而在我搜到的大量中文教程上还都提到了方法`
latexify.with_latex
`，以下将逐一介绍。不过无论哪一种方法，导包都是必不可少的：

```python
import math
import latexify
```

### `latexify.function`

我们需要以装饰器的形式使用`latexify.function`，比如对于一个简单的一元二次求根函数：

```python
def root(a, b, c):
    return (-b + math.sqrt(b**2 - 4 * a * c)) / (2 * a)
```

我们只需要将其装饰为：

```python
@latexify.function
def root(a, b, c): ...
```

接下来`print(root)`打印我们的函数：

```latex
\mathrm{root}(a, b, c) = \frac{-b + \sqrt{b^2 - 4ac}}{2a}
```

让我们以`latex`的形式查看：

$$
\mathrm{root}(a, b, c) = \frac{-b + \sqrt{b^2 - 4ac}}{2a}
$$

是不是非常 amazing 呢？

### `latexify.expression`

`latexify.expression`的使用方法及功能与`latexify.function`非常像：

```python
@latexify.expression
def root(a, b, c): ...
```

仍然使用`print`打印并使用`latex`显示：

$$
\frac{-b + \sqrt{b^2 - 4ac}}{2a}
$$

相信聪明的你已经看出来这两种方法的区别了，接下来请你试试调用我们的`root`函数看看和装饰前有没有什么区别吧~~（显然是没有的）~~。

### `latexify.get_latex`

如果你不喜欢装饰器的写法~~（怎么可能有人不喜欢装饰器）~~，大可以以函数调用的方式获得`latex`字符串，下面的代码将达到与`@latexify.function`一致的效果：

```python
def root(a, b, c): ...
print(latexify.get_latex(root))
```

##### `latexify.with_latex`

这个装饰器的使用方法与效果似乎与`latexify.function`一致，我还没有来得及深究，如果有清楚的同志还请评论区补充……

## `latexify` 参数

接下来介绍一些控制最终输出的参数

### `identifiers: dict[str, str]`

上述参数用于控制一些简单的变量或者函数名的替换

```python
identifiers = {
    "my_function": "f",
    "my_inner_function": "g",
    "my_argument": "x",
}
@latexify.function(identifiers=identifiers)
def my_function(my_argument):
    return my_inner_function(my_argument)
```

$$
f(x) = \mathrm{g}\left(x\right)
$$

### `reduce_assignments: bool`

这个参数设为`True`将把`return`语句中的所有变量与函数内赋值的变量进行组合，以下是示例：

```python
@latexify.function(reduce_assignments=True)
def f(a, b, c):
    delta = b**2 - 4 * a * c
    numerator = -b + sqrt(delta)
    denominator = 2 * a
    return numerator / denominator
```

$$
f(a, b, c) = \frac{-b + \sqrt{b^{2} - 4 a c}}{2 a}
$$

`False`的结果显而易见，此处略。

### `use_math_symbols: bool`

该参数控制是否自动将具有符号名称的变量转换为LaTeX符号。

```python
@latexify.function(use_math_symbols=True)
def greek(alpha, beta, gamma, Omega):
  return alpha * beta + math.gamma(gamma) + Omega
```

$$
\mathrm{greek}({\alpha}, {\beta}, {\gamma}, {\Omega}) = {\alpha} {\beta} + \Gamma\left({{\gamma}}\right) + {\Omega}
$$

### `use_set_symbols: bool`

该参数控制是否使用二进制运算符进行集合运算。

```python
@latexify.function(use_set_symbols=True)
def f(x, y):
    return x & y, x | y, x - y, x ^ y, x < y, x <= y, x > y, x >= y
```

$$
f(x, y) = \left( x \cap y\space,\space x \cup y\space,\space x \setminus y\space,\space x \mathbin{\triangle} y\space,\space {x \subset y}\space,\space {x \subseteq y}\space,\space {x \supset y}\space,\space {x \supseteq y}\right)
$$

### `use_signature: bool`

查看下面的示例，顺带对比一下`latexify.function`和`latexify.expression`，这个参数的作用就显而易见了。

```python
@latexify.function(use_signature=False)
def f(a, b, c):
    return (-b + math.sqrt(b**2 - 4 * a * c)) / (2 * a)
```

$$
\frac{-b + \sqrt{b^{2} - 4 a c}}{2 a}
$$
