The triangle of the value-creation industry

A project is an activity, limited in time and scope, which transforms an organisation from an initial state into a target state. The project management triangle [1] correlates cost, time, scope and quality of a project and emphasizes that project management choices regarding these factors affect results. All interpretations of the project management triangle I'm … Continue reading The triangle of the value-creation industry →

Azure: Service API already exists

Update 2023/01/04: I was wrong. Microsoft Support pointed out that each external APIM instances is assigned a globally unique DNS entry and mine was just too generic. Giving the API management resource a unique name for the region it runs in (eg. by appending a random number) solves the issue. I'm writing a Terraform template … Continue reading Azure: Service API already exists →

Running clamav in Docker under Linux

I'm running ClamAV [1] on an Ubuntu 18.04 server in Docker and wanted to document, for posteriority and my own dementia, the setup process and considerations. Thankfully there is an official (?), well-maintained ClamAV image on Docker hub. ClamAV can run stand-alone or as a tandem of CLI tool and daemon - I prefer the … Continue reading Running clamav in Docker under Linux →

My home NAS setup, 2022 edition

This post is an update of the my 2020 home NAS setup. A few things changed since then, the most important the introduction of snapraid for the media and archiving portion of the NAS. The hardware hasn't changed much apart from a (preventive) hard-disk replacement; my admiration and gratitude goes to HP for building a … Continue reading My home NAS setup, 2022 edition →

構建完美、廉價的家庭使用網絡附加存儲 (NAS)

這是第一次出現在這裡的帖子的自動翻譯： https://blog.georgovassilis.com/2020/04/01/building-the-perfect-cheap-diy-nas/ 這篇文章在 Hacker News 上得到了廣泛的討論。這篇文章討論了硬件注意事項、安裝 Linux、設置軟件 RAID、穩健性和處理數據損壞。我已經在家裡運行了十年的自建 NAS，所以我想我會寫下我的經驗，以便其他人可能會為我的許多失敗而幸災樂禍，並為我的幾次勝利而驚嘆不已。 HP Proliant 微服務器 gen8 價格實惠、結構緊湊，可在 Ubuntu 上運行 NAS 是完美的，因為它簡單、安全、模塊化和可擴展，而且價格便宜，因為它是由二手商品零件製成的。 NAS 主要將文件（文檔和媒體）存儲在軟件 RAID 6 上，並通過 Windows 共享將它們提供給本地網絡。我遠離專有 NAS 解決方案，因為如果沒有完全相同的硬件更換，硬件故障會使數據恢復變得幾乎不可能。在這十年裡，從硬盤到機箱和主板的每一塊硬件都被換成了別的東西，有時甚至不止一次，所以對模塊化的關注是有回報的。由於長期數據完整性和穩健性是一個問題，NAS 應該運行某種冗餘 RAID 級別。目標目標描述解決方案功能NAS作為家庭使用的網絡附加文件系統； NAS 每天運行幾個小時，大部分時間處於關閉或待機狀態商品硬件，開源軟件，模塊化，保持簡單互操作性常用的計算機平台應該可以訪問 NAS 上的文件。商品硬件應該能夠連接到 NAS。Ubuntu、USB、SATA 上的 Samba（又名 Windows 共享）。將 LAN 連接到 Wifi 路由器，進行名稱解析和時間服務器。使用 SSH 訪問和管理。模塊化硬件和軟件組件應可互換，無需重新設計整個系統x86 … Continue reading 構建完美、廉價的家庭使用網絡附加存儲 (NAS) →
