此文将讨论acg.watch网站的定位，运营模式，以及潜在应用等。
This article will discuss the positioning, operating mode, and potential applications of the acg.watch website.
缘由
自从18年第一次尝试建站以来，追求流媒体播放服务一直是我所追求的目标。
历史
从2018年三月，我第一次通过腾讯云Win Server 2012实现了对摇曳露营第3集的发布，从而使其能够在网页上访问。到2018年9月，基于video.js，我第一次搭建了一个视频网站，使用华为云对象存储以及mysql数据库进行集中管理，并将其发布在video.yimian.xyz。2018年11月，配合树莓派3B以及一个红外摄像头，我通过推流实现了对宿舍的24小时监控。2019年2月，我购买了acg.watch这个域名，并将视频站转移至此。此后，我站视频被爬多次，由于华为云存储巨额的流量费用，我觉定暂时停止公开提供服务。2019年11月，在英国，我重构了视频站，不再使用华为云存储这个烧钱的服务，转而寻求onedrive存储方案。此外，新的视频站不再拥有后端，而是使用file-cache机制通过分析onedrive的视频目录自动生成数据集。2020年8月，随着ushio用户系统竣工，视频站开始支持为用户提供个性化服务，包括跨设备播放记录同步等。2021年1月，确定acg.watch的发展方向为多功能在线播放器，此外网站还将提供番剧搜寻功能。同时，考虑到版权问题，我之前私藏的所有视频全部转为私有，只有认证过的朋友们才有权限观看。

定位
Acg.Watch视频站拥有三个发展定位：
- 番剧资源辅助搜索
- 多功能视频播放器
- IoTcat的私藏视频站
发展状态
网站将持续开发，欢迎大家常来踩踩呀(:з」∠)
Reason
Since the first attempt to build a website in 18 years, the pursuit of streaming media playback services has always been my goal.
History
From March 2018, I realized the release of the third episode of Sway Camp through Tencent Cloud Win Server 2012 for the first time, so that it can be accessed on the web. By September 2018, based on video.js, I built a video website for the first time, used Huawei Cloud object storage and mysql database for centralized management, and published it on video.yimian.xyz. In November 2018, with the Raspberry Pi 3B and an infrared camera, I realized 24-hour monitoring of the dormitory through push streaming. In February 2019, I purchased the domain name acg.watch and transferred the video site to it. Since then, my site’s video has been crawled many times. Due to the huge traffic cost of Huawei Cloud storage, I feel that I will temporarily stop publicly providing services. In November 2019, in the United Kingdom, I restructured the video site and stopped using Huawei Cloud Storage, a money-burning service, and turned to onedrive storage solutions. In addition, the new video station no longer has a backend, but uses the file-cache mechanism to automatically generate a data set by analyzing onedrive’s video catalog. In August 2020, with the completion of the ushio user system, the video station began to provide users with personalized services, including cross-device playback and recording synchronization. In January 2021, the development direction of acg.watch is determined as a multifunctional online player, and the website will also provide a fan drama search function. At the same time, taking into account the copyright issue, all the videos that I have privately collected before are all turned into private ones, and only authenticated friends can watch them.
Website address
Positioning
Acg.Watch video station has three development positions:
- Assisted search for fan drama resources
- Multifunctional video player
- IoTcat’s private video station
Development status
The website will continue to be developed, and you are welcome to step on it often_(:з」∠)_

最近在物联网开发中使用Arduino搭建LoRa网关和节点，发现在调用String时总遇到一些奇奇怪怪的现象。经过排查，发现是由于其它地方[]=运算符的重载所导致。
Recently, I have used Arduino to build LoRa gateways and nodes in the development of the Internet of Things, and I found that some strange phenomena are always encountered when calling String. After investigation, it was found that it was caused by overloading of the []= operator elsewhere.
为了方便，在开发节点时，我们使用了LoRa-Socket和ArduinoJSON作为依赖。我们发现这两个依赖分别使用时表现良好，但如果在同一个项目文件中使用，则会导致一些怪异的问题。
情况一
通过指针调用函数时String参数传递异常。代码如下：
1 | inline static void _onReceived(const String& msg, const String& from, const String& to, const String& type){ |
在这个案例中，我们发现msg等String在此函数中的数值是一切正常的，可是却没有能够成功传递到_f中。经过一系列骚操作，我们得出如下结论：
- 发现如果将String换成int或其它类型，则参数传递至_f一切正常。有问题的只有String和char类型。
- 我们尝试过将String转换为其它类型，再转回，但是没有效果。
- String或char类型全局变量的声明会使单片机崩溃。
- 当我们将ArduinoJSON依赖删去，String参数的传递则一切正常。
我们从而可以得出，这种怪异现象是由于与ArduinoJSON包的冲突所致。
情况二
在使用ArduinoVector制作String类型Vector时，我们也发现了String类型的不稳定现象。神奇的是，这种现象只出现在String的使用中，其它如int类型运作良好。
这些不稳定现象可以总结如下：
- 赋值时被截断
- String值局部乱序
- String值部分乱码
- 作为参数传给函数时会失败，读取出来是空(与案例一类似)
综述
通过上述两个案例，我们可以初步总结出，这是由于[]=赋值运算符的重载与String有冲突。只要使用[]=重新定义String，即有可能出现String怪异的问题。
For convenience, we used LoRa-Socket and ArduinoJSON as dependencies when developing nodes. We found that these two dependencies perform well when used separately, but if used in the same project file, it will cause some weird problems.
Situation One
When calling a function through a pointer, the String parameter passing is abnormal. code show as below:
1 | inline static void _onReceived(const String& msg, const String& from, const String& to, const String& type){ |
In this case, we found that the value of msg and other String in this function is all normal, but it was not successfully passed to _f. After a series of Sao operations, we come to the following conclusions:
- Found that if you change String to int or other types, the parameters passed to _f are all normal. Only the String and char types are problematic.
- We tried to convert String to other types, and then back, but to no avail.
- The declaration of global variables of type String or char will crash the microcontroller.
- When we delete the ArduinoJSON dependency, the passing of String parameters is normal.
We can conclude that this strange phenomenon is caused by the conflict with the ArduinoJSON package.
Situation Two
When using ArduinoVector to make a String type Vector, we also discovered the instability of the String type. The magic is that this phenomenon only occurs in the use of String, other types such as int work well.
These instabilities can be summarized as follows:
- Truncated during assignment
- String values are locally out of order
- Part of the String value is garbled
- It will fail when passed as a parameter to the function, and it will be empty (similar to case 1)
Summary
Through the above two cases, we can preliminarily conclude that this is due to the conflict between the overload of the []= assignment operator and String. As long as you use []= to redefine String, string weird problems may occur.
