（大学时期加入的协会）

有同学发[帖子](https://hackertalk.net/posts/317200937748385792)提到这个问题，想必很多人也很好奇，我就简单讲一下。

### 为什么有这个网站？

我是一个比较 hack 的人，喜欢捣鼓各种技术，以前硬件玩的比较多（数字、模拟、射频都有），现在做的都是软件相关。这个过程中我就发现交流是非常重要的，即使能力很强也不能闭门造车，特别是技术选型，选错了会走很多弯路，充分交流能够暴露各种技术栈的优缺点，在毕业之后，交流途径更少了，我尝试在网上寻找交流的渠道，但都无法匹配我的需求：实时性、优质垂直内容、良好体验、开放公平。

* CSDN：大量抄袭、低质内容、界面体验差
* 掘金、SF：长内容质量不错，但缺少实时交流渠道（只能发站内信）
* 知乎：长内容质量高、功能丰富，但人群&内容泛化，不够垂直定制 & 实时
* v2ex：短内容质量高、垂直度高，但 UI 体验不够好，导致很多丰富功能无法拓展

于是打算自己实现一个短内容平台，就像黑客说的口号一样：技术驱动优质交流。

### 如何的实现？

做技术的时候我不会去考虑我会不会的问题，我只分析可行性，然后挑战实现过程的每个困难，我觉得 web 更加开放、公平，那就用 web 技术栈；我觉得编辑器能够明显改善用户体验，那我就去实现（编辑器开发是前端 top3 的难题）；大量广告会影响用户体验那就砍掉（只留一个做统计分析）；用户设备种类多，那就去实现 UI 全端兼容、多点登录、数据同步（目前支持同一账号 5 个设备同时登录、同时聊天）。

（大二做的一个信号发生器，带一个椭圆滤波）

各种框架、编程语言本质都是工具，都有优缺点，不要限制自己，python 适合数据分析，react 更灵活、Java 在 web 后端生态更丰富、golang 更加轻量、优雅，nodejs serverless 友好，只用这些技术好的一面，不求强行推到各个领域。如果按这个的思路去解决问题，你会发现做出来的东西会优于现有产品。

### 如何盈利？

软件盈利方式本质只有几种：广告收入、服务收入、电子商务。

**广告收入** ：目前广告在 web 端基本是凉了（大陆范围），用户普遍对广告反感，点击率和点击单价都低，英文站点会好一点，黑客说不会把这个当作主要盈利方式，目标能够支持网站的基本运营即可，如果影响用户体验则砍掉。

**服务收入** ：这种是后续主要的盈利方式，如 docker 企业私有化部署版本、第三方服务对接等、模块拆分、想象空间比较大。这种方式可以兼顾大部分人的使用体验的同时实现盈利，但前提是社区要能够做起来（目前比较困难，希望大家多多支持）。

**电子商务** ：无计划。

同理，flutter reactNative 也是一样的

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。

拉取了rustbuster的v3.0.3版本文件, 二进制文件无法使用, 执行结果如下:

```bash
[root_cn@archlinux target]$ ./rustbuster-v3.0.3-x86_64-unknown-linux-gnu
./rustbuster-v3.0.3-x86_64-unknown-linux-gnu: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
```

拉取了main源码, 想自行尝试编译, 然后卡在了openssl, 以下为报错信息:

  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
warning: build failed, waiting for other jobs to finish...
```

经过检查openssl与rust均为最新版本, 

```bash
[root_cn@archlinux target]$ sudo pacman -S rust
[sudo] password for root_cn:

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.
