Firefox supports hardware video acceleration via VA-API and Wayland. Both Intel and AMD support VA-API. NVIDIA needs to use the open-source Nouveau or nvidia-vaapi-driver. “Hardware video acceleration” and “Firefox” on ArchLinux are very useful and detail resource. (more…)

CRM 不單純是一個資訊系統，他的欄位與作業流程，其實就是不斷演化的業務工程管理 (Sales Engineering)

Steve Sue 在 LinkedIn 分享閱讀財務煉金術的感想：“…將公司財務部門從單純只作收付與記帳的後勤單位，升級成主動透過財報檢視提高公司競爭力並降低財務風險的策略單位…提升企業的資本配置能力，可以讓公司走得更長久…” 我非常贊同他的觀點：從記帳升級到財務管理，才能提高資本配置效率，發揮資料的價值。 不光是財務部要拉高視野與思維，業務部門同樣需要反思傳統管理業務的日報表，引入科學化的現代銷售管理方法論，學習審視資源配置，才能提高業績。 CRM 不單純是一個資訊系統，他的欄位與作業流程，其實就是不斷演化的業務工程管理 (Sales Engineering)。考慮到單純將紙本作業改為電腦紀錄並不會自動提升銷售業績，因此，在系統導入的同時，我組織多場課程，說明各種銷售方法論（例如 IBM 的…

Business Analyst 的工作職掌每家公司差異很大，不要被頭銜迷惑。細讀說明並且在面試時確認未來發展方向，挑選適合自己的職涯！

Business Analyst 是一個近幾年在顧問圈之外開始受到關注的職位，但在電子製造業還是比較新的工作，在金融與電商比較常見。 關於 Business Analyst 的工作，Snoza Tang 已經寫清楚商業與業務分析師的工作職掌，大前研一的企業參謀就是紀錄當時他作最基層的顧問 Business Analyst 的心得筆記。 來自 J.P.Morgan 的小 Lin也有錄製短視頻說明美國的 DA/BA/DS 工作內容。 我認為分享內容中的業務分析師是 Business Analyst，而商業分析師是 Data Analyst，我的客戶也有各自的定義，建議閱讀與問清楚 Job…

CRM 的寶貴資料不只是協同作業與記錄，進階應用有快速建立內部知識(Knowledge)；設置 Business Analyst 定期分析，改善作業流程。讓數位化的資料搭配管理科學發揮更多價值，才是 CRM 的真正優勢。

最近因為先前購置的電腦記憶體有問題，透過原廠網站回報。在客服人員積極協助下，判斷是問題商品與包裝敘述不同導致。最後以 RMA 流程換貨，順利解決我的問題。 更精確一點：在電商購買 CL19 的標準記憶體，但實際收到的是 CL16 的超頻記憶體。因為外包裝標示 CL19，記憶體標籤寫 CL16，才無法在第一時間判斷。詳細過程請參考 1 與 2。 根據我的經驗，商品瑕疵可能有下面三種方案，通常會走第 3 種。 找出有問題的批號回收，重工更換商品標籤再寄回，客戶會抱怨於事無補。找出有問題的批號回收，重工更換記憶體再寄回，客戶會抱怨記憶體延遲增加。等待客戶抱怨或維修，由代理商或客服部門走 RMA 流程更換，客戶會抱怨記憶體延遲增加。 Intel Pentium 的 FPU 瑕疵是第 1 種，但是 C2000 與相關 Atom 系列瑕疵是第 3 種，而且僅是由採用 CPU…

Load dri3 module and enable tearfree to improve screen refresh with Intel GPU on Ubuntu.

I use the portrait mode in Ubuntu 20.04 running wayland on i5-9500. The build-in Intel HD Graphics 530 has tearing issues: refresh slowly while scrolling. After several testing, the solution is to load the dri3 module and enable the “TearFree” option in 20-intel.conf or 20-intel-graphics.conf: $sudo nano /etc/X11/xorg.conf.d/20-intel.conf Section "Module" Load "dri3" EndSection Section…

The Max Power for an ATX 4-Pin CPU Power Connector is 108W

Because the i5-9400F consumes 80W at-wall while loading 300 tabs in Chrome, which is a huge jump from 30W at idle, I want to know if it is safe using the only 4-pin CPU power connector on Gigabyte H310M S2V 2.0 (rev. 1.0).

Wiki： ADO

DAO focus on local database. The performance is poor while accessing remote database through ODBC.

RDO supports accessing remote machines through ODBC.

ADO contains ADO DB that is an API layer of OLE DB which is another layer of ODBC. It replace DAO and RDO. It requires JRO for replication which is build-in in DAO.

ADOX = ADO extension for DDL and secutiry.
