最近发现在zotero中用webdav方式同步文献不成功，两台笔记本上的文献条目和附件有差别，不知道什么时候起发生的。然后分别配置了使用了一下infini-cloud和坚果云的webdav，观察到连不上和没有同步的情况。猜想可能是学校的网络有些问题，于是找了个盒子装了个固态硬盘，然后改用zoteroportable的版本了，今后随身就得多带一个盘了。
另外，win11上配置的wsl中的emacs又不能正常开机启动了，不知道是什么升级影响了它，于是win下转到了vscode，懒得搞了。

众所周知，amdgpu开源驱动的opengl硬件加速性能比amdgpu-pro闭源显卡更好，但其通过mesa实现的opencl只能支持到1.1版，而且并不总能正常的工作。如果能在开源显卡驱动的基础上安装闭源驱动中的opencl支持，显然是非常好的事情。好在AUR中就提供有这样的方案。

最近收到ankiweb的通知，告知因为长时间没有登录，我的账户已经被注销了。我确有用记忆卡片的需要，但是最近太慢，实在顾不上总去使用它，anki的做法让人很无奈。鉴于此，还是决定自己搭建一个anki同步服务器。
github上的tsudoko建立了一个项目[1]，可以搭建anki 2.1的同步服务;在archlinux的AUR网站上，s7hoang则对它进行了规范化的打包[2]，可以使用systemd来启动和管理这一同步服务器。不过，CentOS和Archlinux有一些不同，s7hoang的方案用在CentOS服务器上需要做一定的调整。
对s7hoang的方案进行小调整后，我在CentOS 7服务器上安装anki-sync-server的过程如下。
s7hoang的AUR包[realasking@myserver]$ wget https://aur.archlinux.org/cgit/aur.git/snapshot/anki-sync-server-git.tar.gz
[realasking@myserver]$ tar -xzvf anki-sync-server-git.tar.gz
[realasking@myserver]$ cd anki-sync-server-git
s7hoang提供的anki-sync-server.service，内容改为：[Unit]
Description=A sync server for anki
After=network.target
[Service]
Type=simple
User=anki-sync-server
Group=anki-sync-server
WorkingDirectory=/opt/anki-sync-server
ExecStart=/usr/bin/python36 -m ankisyncd
StartLimitIntervalSec=1
Restart=always
RestartSec=5
[Install]
WantedBy=multi-user.target
s7hoang的方法创立脚本genpack.sh，内容如下：#!/bin/bash
git clone https://github.com/tsudoko/anki-sync-server
cd anki-sync-server
mkdir -p "plugins/anki2.0"
mkdir -p "plugins/anki2.1/ankisyncd"
mkdir -p "plugins/systemd"
cp ../anki-sync-server.py "plugins/anki2.0"
cp ../__init__.py "plugins/anki2.1/ankisyncd"
cp ../anki-sync-server.service "plugins/systemd"
sed -i "2s/0\.0\.0\.0/$(ip route get 1.2.3.4 | awk '{print $7}')/" \
plugins/anki2.0/anki-sync-server.py
sed -i "3s/0\.0\.0\.0/$(ip route get 1.2.3.4 | awk '{print $7}')/" \
plugins/anki2.0/anki-sync-server.py
sed -i "3s/0\.0\.0\.0/$(ip route get 1.2.3.4 | awk '{print $7}')/" \
plugins/anki2.1/ankisyncd/__init__.py
sed -i "s/python/python36/g" ankisyncctl.py
git submodule update --init
然后执行这个脚本。
nginx服务器脚本anki.conf，内容如下：server {
listen 80;
server_name anki.myserver.tk;
return 301 https://$server_name$request_uri;
}
server {
# Allow access via HTTPS
listen 443 ssl http2;
listen [::]:443 ssl http2;
# Set server names for access
server_name anki.服务器名.tk;
# Set TLS certificates to use for HTTPS access
ssl_certificate /etc/letsencrypt/live/服务器名.tk/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/服务器名.tk/privkey.pem;
location / {
# Prevent nginx from rejecting larger media files
client_max_body_size 0;
proxy_pass http://127.0.0.1:27701;
}
}
root登录服务器，将anki-sync-server文件夹拷贝到/opt下将anki-sync-server.service文件拷贝到/etc/systemd/system下
将anki.conf文件拷贝到：/etc/nginx/conf.d下
建立anki用户
[root@myserver]# useradd -d /opt/anki-sync-server -r -s /sbin/nologin anki-sync-server
[root@myserver]# chown -R anki-sync-server /opt/anki-sync-server
[root@myserver]# chgrp -R anki-sync-server /opt/anki-sync-server
[root@myserver]# sudo -u anki-sync-server ./ankisyncctl.py adduser
[root@myserver]# systemctl enable anki-sync-server
[root@myserver]# systemctl start anki-sync-server
[root@myserver]# systemctl restart nginx
依赖关系的解决本文未提及，因为[1]中已经讲得很清楚了，大家可以直接查阅原作者的叙述。

之前投稿被拒，要更换期刊，结果在用noteexpress（NE）格式化参考文献时发现，有些引用文献的期刊名被正确缩写，有些缩写是错误的，有些则完全没被缩写。将NE自带的对应期刊的Reference Style（RS）复制了一份，然后对照csl修改未果，将几种内置缩写格式都试了一遍，也都不正确，万般无奈下决定更换Mendeley。
要更换Mendeley，需要先删除掉NE已经插入的引用。NE是采用域的形式添加引用的，在网上搜索，很多人都提到搜索全部域，然后删除即可，但是这样会伤及无辜，影响已输入公式、晶向、通讯作者等信息。最后查找微软帮助，解决问题，过程如下：
1. 在正文中显示域代码
在联想笔记本上输入：Alt+Fn+F9
在其它笔记本上输入：Alt+F9
2.打开搜索
Ctrl+H
3.搜索特定域，并用空内容替换
点击替换
点击特殊格式，在弹出菜单中选择域，此时在查找内容中出现:
^d
在其后输入 ADDIN NE.Ref.
即：^d ADDIN NE.Ref.
保持替换为中啥都没有
点击全部替换
4.关闭对话框
5.隐藏域代码
操作同1.
然后就可以看到，NE插入的东西都很轻松的干掉了。

最近在写一些东西，需要翻译一些文献以初步筛选，但是受限于自己的英语水平，完全手动弄太慢了，于是打算找一些自动翻译的办法。
但是尝试了很多办法，遇到了若干问题，比如：（1）谷歌翻译在国内时灵时不灵、且只能翻译一部分，（2）百度翻译必须手动一段一段的粘，（3）先将pdf转换为html、再用浏览器插件调用百度或谷歌翻译会出现某些段翻译了，某些段还是英文的情况，（4）迅捷pdf在线翻译直接传pdf译文和原文就重叠在一起、并且原文未全部翻译，而传转换后的word文档会发现翻译的内容只有前4页或前5页，（5）网上若干python代码都有版本兼容性问题，有些还仅限于特定的操作系统，解决起来很麻烦，并且有些解决之后，使用中发现还是只能翻译文献的部分内容。（6）一些离线的翻译软件现在已经无法安装或安装后无法使用了，新版本没有找到。
最后确定必须使用在线的翻译，而且只能上传word文件，pdf文件翻译会遇到很多问题，具体做法分为两步：
1.把pdf转为word
直接使用联想随小新潮7000预装的office2016里的word打开pdf文件就可以完成转换，然后另存就行了，不需要使用其它工具。
2.把word文档翻译为中文
这一步有两个做法：
一是安装巴比伦客户端，然后直接在文件上单击右键，在弹出菜单上选翻译即可。
这个做法很方便，但是翻译得非常粗糙，基本只有摘要可以勉强看看。
巴比伦客户端的下载地址是：
https://www.babylon-software.com/
另一是访问彩云科技 ，然后用微信扫码登录，并点击在线翻译。
在线翻译左边有一个上传文档按钮，点开上传word文档，然后点击翻译。
翻译完成后，不要点击下载，而是要点击个人中心，在我的文档里点击Word下载，这样就可以获得完整的、基本能看的翻译文献了。
