    ## solution 其实是升级后 tailscale 提示我的. ```shell ❯ tailscale status # Health check: # - dns-manager: systemd-resolved and NetworkManager are wired together incorrectly; MagicDNS will probably not work. For more info, see https://tailscale.com/s/resolved-nm # - dns-os: setLinkDNS: Could not activate remote peer. ...

    CS9 (CentOS Stream 9) 发布也挺久了. 一直没有升级, 主要是官方一直没有发布升级指南. 这一点 CentOS 比较坑 (当然, RHEL用户是可以从RHEL8 升级 RHEL9的). reddit 上甚至有 RHEL 的员工回复: Q: How to upgrade from Stream 8 to Stream 9? A: > rbowen2000 1 yr. ago > Red Hat Employee > No. There is not currently a way to do an in-place upgrade between C8S and C9S, nor do we expect for there to be one. This is one of the questions that gets asked at each of our CentOS Dojo AMA sessions, and the answer is typically along the lines of "Red Hat Engineering isn't interested in this feature for RHEL, and so it won't be worked on for CentOS. However, if someone from the community works on it, that would be awesome." ...

    ## 缘由 其实是 O'Reilly Learning 终止了和 ACM 合作. 毕竟 499刀的会员, 几十美元买个 ACM 会员就能白得. O'Reilly 估计觉得这已经影响到它自己卖 O'Reilly Learning 会员了. 这无疑是 ACM 的损失, 也是我们这些羊毛党的损失. 没有了 免费 O'Reilly Learning 资料库的 ACM 会员对于我来说, 毫无用处. https://web.archive.org/web/20220702061717/https://learning.acm.org/e-learning/oreilly Use promo code ACM10022 to receive an introductory one-year subscription for $399 (plus VAT/Tax). ...

    今天检查邮箱发现 https://github.com/toml-rs/toml-rs/issues/392 这个 issue 有更新. 由于 `toml` 这个 crate 完成的时候, TOML 标准本身还没有达到 1.0.0 稳定版, 因此这个 crate 实际上只实现了 TOML 标准 0.5 版本的功能. 但是现在 TOML 标准已经到了 [1.0.0 版本](https://toml.io/en/v1.0.0), 而 `toml` 这个 crate 的维护者却一直没有更新. 由于有了这个 issue, 讨论何时更新到1.0版本. 这是一个 2020 年的 issue. 一直没啥动静, 值得高兴的时候, 昨天终于有变动了: ...

    老灯用的是 Nvidia 显卡闭源驱动. 显示器是 4K 的. 这操作基本上是每次装机后必备的, 这里记录下. ## Linux Console 字体太大了 默认情况下有个问题就是: console 下面的字体太大了. 字体太大了, 是因为 frame buffer 分辨率太低了, 最简单的做法就是把 console 字体调小一点. 纯 console 下的字体是点阵字体. 默认的字体有点丑, 装个 terminus 吧: ```shell paru -S terminus-font ``` 切到 console 看下效果: ```shell setfont ter-d14b ``` 我这里设置 14 号是因为默认的太大了, 14相对较小一些. 另外 12 的话点太明显了, 不够清晰. ...
