简单的解决办法就是，使用WINRAR，添加到压缩文件-压缩后删除源文件。
搞定。

git下载指定版本的代码并制作patch以及如何打patch
首先使用git clone把代码更新到本地。
使用git log –grep=word 搜索指定的版本。
gcc@gcc-x64:/mnt/AX3600$ git log –grep AX3600
commit 9d8a34c9abb6c13f9bebc28d9c4c10fe512491d4 (HEAD -> newBranch)
Author: lean <coolsnowwolf@gmail.com>
Date: Mon Jun 14 20:08:28 2021 +0800
ipq807x: add Xiaomi AX3600 and ath11k support
生成指定版本的patch：
git format-patch -1 9d8a34c9abb6c13f9bebc28d9c4c10fe512491d4
应用patch：
先检查patch文件：git apply –stat newpatch.patch
检查能否应用成功：git apply –check newpatch.patch
打补丁：git am –signoff < newpatch.patch
(使用-s或–signoff选项，可以commit信息中加入Signed-off-by信息)
如果需要撤回刚才打上的那个Patch，使用命令：git apply -R ***.patch

使用git apply –reject file.patch 这个命令会自动合入不冲突的代码，然后保留冲突的部分，同时在冲突的文件夹下面会生成后缀为.rej的文件，用于保存没有合并进去的部分，可以参考这个进行冲突解决。
解决完冲突后，删除后缀为.rej文件，并执行git add . 添加改动到暂存区，然后git commit -m “注释语句” 增加commit。
最后git log 查看刚才的commit，然后生成指定版本的patch：
git format-patch -1 9d8a34c9abb6c13f9bebc28d9c4c10fe512491d4

unixbench使用方法
wget –no-check-certificate https://github.com/teddysun/across/raw/master/unixbench.sh
chmod +x unixbench.sh
./unixbench.sh
登录ssh之后，输入上面的脚本回车即可开始测试。

可以看出，J1900的CPU还是很强悍的。I5-8250U理论上相当于5倍的J1900性能，但是由于在hyper-v虚拟机下面测试，性能折损较大。
关于不同CPU性能测试，可以参考这篇文章。

openwrt运行青龙面板不联网的解决办法
openwrt下创建基于bridge模式的容器，默认是无法访问公网的，只能lan访问。
解决办法就是创建host网络而非bridge。
host模式下容器是直接联网的，无需端口映射，也无需debug。
直接在ssh下运行
docker run -dit \
-v $pwd/ql/config:/ql/config \
-v $pwd/ql/log:/ql/log \
-v $pwd/ql/db:/ql/db \
-v $pwd/ql/scripts:/ql/scripts \
-v $pwd/ql/jbot:/ql/jbot \
-e ENABLE_HANGUP=true \
-e ENABLE_WEB_PANEL=true \
–name qinglong \
–hostname qinglong \
–restart always \
–net host \

刚给猫打了一针，叫声那个凄惨啊。
狂犬和猫三联买回来快一周了，拖延症发作加上畏难情绪迟迟没有下手。
今天晚上终于果断开打，先带上伊丽莎白圈，然后用胶布捆住猫腿，老婆带上厚手套摁住猫。
打针视频看了几遍，感觉是时候开始实践了。
捏起脖子后面的皮，找准位置，第一针没经验，扎进去一点点。猫开始挣扎惨叫，中止。
第二针扎进去了，但是手没放在推注射器的位置，猫剧烈挣扎大声惨叫，果断拔出。
老婆开始表现出不耐烦：叫你去宠物医院打，你不去，非自己折腾，没那个材料就不要学人家嘛。看看都把猫折腾成啥样了。
其实不是不想去宠物医院，主要是信不过他们，假猫三联疫苗太多了，他们打疫苗的价格比我从网上买来自己打都便宜很多，我看够呛。
心里默念凡事都有第一次，果断顶住压力，进针，先是有阻力，随之突然轻松，有扎进空腔的感觉。到位了。
猫开始撕心裂肺的狂叫，果断推入，成功。
解开捆绑拆下脖圈，猫蜷缩在电脑椅上显得十分委屈，赶紧蒸了点肉来安抚一下。
这会又开始活蹦乱跳了。
