世間本無「耶和華」

「耶和華」的希伯來文只以四個輔音符號JHVH為代表,
讀作「亞偉」(Jahveh)。由於猶太人不敢妄稱上帝之名,
於是遭到JHVH時就讀「阿東乃」(Adonai),即稱「主」(Lord)代替之。

公元六,七世紀時,猶太教瑪瑣拉學者創造希伯來文元音符號後,
為要提醒人對JHVH應讀「阿東乃」,
所以把「阿東乃」的三個元音e, o, a標注於JHVH之下。

後來基督教繼承猶太教《舊約》,
誤將JHVH和原屬「阿東乃」的三個元音e , o ,a拼讀在一起,
於是就出現「JeHoVaH」(耶和華)這個新名字。

所以「耶和華」是猶太教神名字基督教的誤讀,
現今教會常常高呼「耶和華」是我們的主,實在是一種諷刺。

SATA 6Gbps

原來筆者一直對SATA介面有著錯誤的理解,
筆者看有很多人跟筆者一樣吧。
先看看這份來自SATA-IO的表格:

SATA-IO Specifications & Naming Conventions
Specification RevisionTechnology GenerationData Transfer RateInterface Name
SATA Revision 3.x
(Not 'SATA III')
Third generation
not 'Gen 3'
Up to 6Gb/sSATA 6Gb/s +
[product name]
SATA Revision 2.x
(Not 'SATA II')
Second generation
not 'Gen 2'
Up to 3Gb/sSATA 3Gb/s +
[product name]
SATA Revision 1.x
(Not 'SATA 1')
First generation
not 'Gen 1'
Up to 1.5Gb/sSATA 1.5Gb/s +
[product name]

Important: Do not use the incorrect terms 'SATA II' or 'SATA III'

The references embedded within the SATA specifications to 'Gen 3', 'Gen 2', or 'Gen 1' are technical spec naming conventions only and should not be used for marketing and product naming purposes.

看了這表格後大家也會嚇一跳吧,
原來掛在口邊多時的SATA II並不是介面的名稱。
有趣的是:有很多商店及廠商也犯了同樣錯誤。
難怪SATA-IO要提出書面的澄清了
