幹壞事是進步最大的原動力
在「GPU Survival Toolkit for the AI age: The bare minimum every developer must know」這篇看到的工具，雖然裡面是講 GPU 相關的事情，但看到這段：
inxi -GThis command provides information about the graphics subsystem, including details about the GPU and the display.
inxi 這個工具是用 Perl 寫的，在 manpage 的說明是：
inxi - Command line system information script for console and IRC
提供一些資訊給使用者，方便使用者在問問題時順便複製貼上到 IRC 或是論壇。
看了一下系統的 dependency，我的桌機是因為 xubuntu-desktop 這個套件相依裝進去的，這是 XFCE 桌面環境的套件。
而 Ubuntu 的預設環境沒有包這個套件進去，會需要額外安裝。
Google 的 SRE 團隊整理出過去二十年的心得，當看故事的心態在看的：「Lessons Learned from Twenty Years of Site Reliability Engineering」，在 Hacker News 上也有討論：「Lessons Learned from Twenty Years of Site Reliability Engineering (sre.google)」。
裡面的項目大多都會在公司成長時不斷的導入，都是夠大就會遇到的。
比較有趣的是第六條，這是唯一一條全部都用大寫字母列出來的：
COMMUNICATION CHANNELS! AND BACKUP CHANNELS!! AND BACKUPS FOR THOSE BACKUP CHANNELS!!!
到 Google 這個規模的架構，這邊就會規劃找完全獨立於 Google 架構的方案來用；我猜應該是傳統的 colocation 機房 (像是 AT&T 之類的)，上面跑 IRC server 之類的？
在 Hacker News 上面也有其他人提到 Netflix 也有類似的規劃，需要有一個備援的管道是完全獨立於 AWS 的；另外同一則 comment 裡也有提到 Reddit 的作法是在辦公室裡面放 IRC server 備援：
Yes! At Netflix, when we picked vendors for systems that we used during an outage, we always had to make sure they were not on AWS. At reddit we had a server in the office with a backup IRC server in case the main one we used was unavailable.
IRC 還是很好用的 XD
翻了一下「IRC Network Libera.Chat」與「IRC Network freenode」：
During last connections to Libera.Chat its servers reported an average of 40267 users and 19125 chat rooms. Use the following menu to get more information about IRC network Libera.Chat! Take a view to the generated statistics and search within the list of chat rooms for topics of your interest!
During last connections to freenode its servers reported an average of 26145 users and 23410 chat rooms. Use the following menu to get more information about IRC network freenode! Take a view to the generated statistics and search within the list of chat rooms for topics of your interest!
一陣子沒關注，發現已經甩開了...
前幾天在「freenode 又在提醒大家搬到 Libera.Chat 了...」這邊猜測這個月月底大概會有交叉，結果發現這幾天 freenode 選擇自爆，直接把上面的註冊使用者與頻道都清空：
Ha ha freenode appears to have just removed basically all registered nicks and channels
— Matthew Garrett (@mjg59) June 15, 2021
這個自爆行為直接讓 Libera.Chat 大幅成長，超越了目前的 freenode：
netsplit.de 上的資料看起來是某個比較長時間的平均值，會需要再拉長一些時間才會反應出來。
看到「Last remaining >1000 user community channel seized by freenode staff」這篇，freenode 把 ##linux 頻道給綁走了：
Late in the evening of June 12, 2021, freenode staff seized the largest community channel left on freenode.
新家在 Libera.Chat 上面：
Similar hostile takeovers happened to the Python community, GNU and the FSF. More than 700 FLOSS projects have abandoned freenode and now the Linux.Chat community has left as well; find our new home at #linux on Libera and our multi-platform community website here.
翻了一下「IRC Networks - Top 10 in the annual comparison」這邊的資料，看起來這個月月底有機會交叉？
另外文章裡有提到 OFTC (The Open and Free Technology Community)，看起來也是個對 open source community 開放的資源...
