"Sadservers.com" 是一個軟件即服務 (SaaS) 網站,專門為想要練習和提升他們在Linux伺服器疑難排解方面技能的使用者設計的。這個網站通過提供真實Linux伺服器上的“捕旗(Capture The Flag)”式挑戰來幫助使用者練習。用戶會獲得一個有問題的遠程Linux伺服器,然後他們需要嘗試解決這些問題。這些挑戰包括與Linux相關的常見軟件,如數據庫或Web伺服器等,雖然不一定需要對特定應用程序的細節有深入了解,但也包括需要熟悉相關技術的場景,例如Docker場景。這些場景大多是現實世界中的問題,類似於實際遇到的問題。
該網站主要面向需要伺服器調試和疑難排解技能的專業軟件開發人員、系統管理員、DevOps工程師、SRE以及相關職位的人員。特別是,Sadservers希望以一種對工作面試中的疑難排解部分有用的方式來測試這些專業人士或有志從事這些工作的人。
除此之外,該網站的GitHub頁面還提供了關於如何參與和協作的信息,包括如何創建新的場景和提供反饋。網站的創建者對於新場景的幫助表示歡迎,但他們不需要網站開發方面的幫助。
總之,Sadservers.com是一個適合那些想要提升Linux疑難排解技能、準備SRE/DevOps面試或只是想要在真實環境中測試自己技能的專業人士的平台。它提供了一種實際和互動的學習方式,有助於增強在現實工作環境中遇到的問題的處理能力。
A how-to guide for creating a collaborative and supportive culture
New managers often want to get everything right from the get-go. But, ironically, that would be their first mistake. Why? Because that's the total opposite of authenticity.
A week ago, I attended Kubecon 2023 in Chicago. I read a few blogs and attended some 101 tutorials... Tagged with kubernetes, beginners, architecture, devops.
Go也有struct padding可以優化
Reflecting on my 20-year journey as a software developer, I realize some things I wish I had started doing sooner. These practices, habits, and mindsets would have accelerated my growth, expanded my knowledge, and enhanced my overall experience as a developer.

Approaching interviews with the right attitude can go a long way: stay humble, ask questions, think in tradeoffs, communicate your thought process and listen to your interviewer.
Introduction After struggling a lot with my mental health (anxiety, depressive condition) for several years, I was diagnosed with Attention-Deficit/Hyperactivity Disorder, commonly known as ADHD, at the age of 44. This diagnosis shocked me a lot: I wasn’t a wild child, in fact, I was even a good pupil. With the help of my therapist, […]

你的不明確要求,是他們時間的浪費
在辦公室與遠程工作之間的選擇
Just as Docker makes tasks easier for us, it is interesting to consider the surface risk from a security perspective and the possibilities it offers for privilege escalation.
When you discuss your promotion with your manager, how do you bring it up? What about when you tell a story in an interview? Or give feedback to a coworker? In each of these situations, our intuition often lies. Our intuition tells us things like: If I just tell my manager how much work I’ve done, he’ll appreciate me.
我以為人的生活可以分作三層:一是物質生活,二是精神生活,三是靈魂生活。物質生活就是衣食。精神生活就是學術文藝。靈魂生活就是宗教。「人生」就是這樣一個三層樓。懶得(或無力)走樓梯的,就住在第一層,即把物質生活弄的很好,錦衣肉食、尊榮富貴、孝子慈孫,這樣就滿足了。這也是一種人生觀。抱這樣的人生觀的人,在世間佔大多數。
其次,高興(或有力)走樓梯的,就爬上二層樓去玩玩,或者久居在這裡頭。這是專心學術文藝的人。這樣的人,在世間也很多,即所謂 「知識分子」、「學者」、「藝術家」。
還有一種人,「人生欲」很強,腳力大,對二層樓還不滿足,就再走樓梯,爬上三層樓去。這就是宗教徒了。他們做人很認真,滿足了 「物質欲」還不夠,滿足了「精神欲」還不夠,必須探求人生的究竟。他們以為財產子孫都是身外之物,學術文藝都是暫時的美景,連自己的身體都是虛幻的存在。他們不肯做本能的奴隸,必須追究靈魂的來源,宇宙的根本,這才能滿足他們的 「人生欲」。這就是宗教徒。
我們的弘一大師,是一層一層的走上去的……故我對於弘一大師的由藝術昇華到宗教,一向認為是當然,毫不足怪。
