体验Follow与回归TTRSS #

前几个月，赶着Follow Alpha内测的末班车拿到邀请码，恰巧也收到六千多Power的空投，由此动力十足，深度体验了Follow，有一些感受。

Follow似乎将RSSer孤岛连接起来了，原来还有这么多人在使用RSS。通过列表分享和查看别人的订阅，能发现一些优质订阅源；
Follow降低了RSS的门槛。现在几乎可以无成本的获取订阅源并阅读，不用担心RSSHub风控（现已上线第三方RSSHub订阅），不用再为阅读器付费，不用费劲部署自托管程序；
仅作为一个RSS阅读器，目前的Follow做得并不比其它工具好。网页端的全文获取时常不可用、图片防盗链没解决、更新时间间隔无法自定义等。但是Follow对图片、视频、社交分类浏览做的处理是我用过的最好的。

用了一段时间后，觉得Follow并没有提升我个人的阅读体验（相较TTRSS+FeedMe）：我自制的订阅源反而受到了抓取间隔的限制；部分自制订阅源没有发布在公网上，仅由内网Nginx托管；多媒体仍然习惯在来源网站/APP观看，即便Follow已经做得不错了，但似乎永远不可能媲美来源网站；Follow似乎有被墙的趋势，直连有时不太顺畅。

且让Follow再成长一段时间，我先回归TTRSS，借此对其进行升级和打理。

对Follow的热情消退

整理订阅源 #

精简订阅 #

由于年末的忙碌和体验了一段时间Follow，TTRSS里的未读文章数已经积压到五位数了。有些订阅源居然给我“灌水”了几百篇。大量同质和我不感兴趣的内容淹没了对我有价值的文章，我的信息获取效率实质上降低了。

开刀操作当然是取消订阅，根据TTRSS历史收藏量数据，我排除了一些可能一直是RSS圈的热门订阅，但我却很少阅读的频道。我取消了reddit、果壳、丁香园、知乎日报、掘金、机核等十几个订阅，每日的新增文章居然下降了快一半；
下一步是取消同质化内容订阅。典型的就是中文AI三大顶会：机器之心、量子位与新智元（雾）。至于取消哪些，后面再观察比较一下；

做分类 #

根据订阅源的类别，重新优化了一下分类。

分类很重要：不同类别的内容混杂在一起，浏览效率非常低，按类别浏览可以让大脑预设好严肃或放松状态；
分类也可以让过滤更有效（详见"过滤器"章节）；
我做了9个大类，16个子类，比如科技（大类），视听（大类），学术 | 机器人，学术 | 综合，学术 | 力学小类。

过滤器 #

在之前的TTRSS设置中，我没有清理旧文章，RSS的优势体现出来了：我很方便的按订阅源查看历史文章，为关键词的设置提供了帮助。TTRSS的过滤器支持正则表达式。

以自动标记已读操作为例，我订阅了一些材料方向的频道，但材料领域太大了，我是个外行，且感兴趣的只是一小撮，因此，在学术 | 材料分类内作过滤催化|单晶|原子|太阳能|环氧|蛋白质|量子|铁电|隔膜|高熵|电池|陶瓷|烯|光谱|肽|腐蚀|硅基|自旋|基因|硅酸|拉曼|RNA|DNA|芯片|手性|雷达|合金|电磁，同时在学术 | 综合内作过滤催化|化学|祝贺|细胞|纳米|微信订阅|肿瘤|分子|喜报|癌|基因|免疫|淋巴|病毒。
同理，用过滤器过滤出若干预定义标签，如人形机器人，在全部订阅源中过滤关键词具身|人形机器人|仿人机器人|类人机器人|通用机器人|双足.*机器。

做完以上精简操作后，顿感轻松，每日的新文章数少于一百五，由预定义标签过滤而来的也不过十来篇。有时忙起来而积压的文章，不读也罢，一键标记已读！

升级TTRSS #

我的TTRSS已经一年多没更新了，借此做一下升级，也发现一些小问题。我使用的是HenryQW@Github编制的Awesome-TTRSS，他添加了一些额外插件，以提升用户体验。关于TTRSS的更新，[[https://ttrss.henry.wang/zh/#数据库更新或迁移]]写道:在升级时，请勿跳过多个大版本，例如直接从 13.x 升级到 16.x 是不支援的，并可能导致数据丢失。我现在使用的Postgres版本是13，好吧，那就老老实实按步骤升级吧，由于Postgres加密方式由Version13中的md5改为Version14及以上的SCRAM-SHA-256，因此，Postgres升级13->14时，多加一步重置密码，文档里没有写明这一点。正确的步骤如下：

备份数据库;

mkdir backup
cd backup/
sudo cp -r /var/lib/docker/volumes/ttrss_feed-icons ./
sudo cp -r /var/lib/docker/volumes/ttrss_postgres ./
sudo cp -r /var/lib/docker/volumes/ttrss_themes ./

导出数据库docker exec postgres pg_dumpall -c -U 数据库用户名 > export.sql，wangqiru/ttrss默认数据库用户名为postgres;
停止容器docker compose down;
拉取新镜像docker compose pull;
启动容器docker compose up -d;
导入数据库cat export.sql | docker exec -i postgres psql -U 数据库用户名;
由于postgres加密方式由Version13中的md5改为Version14及以上的SCRAM-SHA-256，因此，postgres升级13->14时，多加以下一步重置密码：

docker exec -i postgres psql -U 数据库用户名
\password
# Enter the password at the prompt!
# ctrl+D to exit

重复以上2-6步，完成postgres14->15,15->16的升级。

此外，几点说明：

我原来只用docker创建了卷，没有在docker-compose.yml所在文件夹内设置映射路径，现将/var/lib/docker/volumes/ttrss_postgres迁移至docker-compose.yml文件夹内；

# docker-compose.yml
services:
	database.postgres:
		volumes:
		  - ./postgres:/var/lib/postgresql/data
#volumes:
#  postgres:

升级完发现订阅源的自定义图标消失了，翻看了wangqiru/ttrss容器内的文件树，发现图标文件存储在了/var/www/cache/feed-icons内，而不是wangqiru/ttrss仓库里写的/var/www/feed-icons；主题文件则是保存在了/var/www/themes和/var/www/themes.local里，而不是/var/www/ttrss/themes。

自定义TTRSS主题 #

用了多年的浅色主题，有点腻了，换个暗色主题。自带的feedly-sepia_night也不那么好看，根据CrackTC/ttrss-nord-theme作了一点细节修改，在偏好设置-主题-自定义弹框内填入以下CSS片段即可：
