AWS 的瑞典機房開了,那香港呢...

AWS 開了 Stockholm 區 (eu-north-1):「Now Open – AWS Europe (Stockholm) Region」。

在「In the Works – AWS Region in Hong Kong」這邊宣佈香港區會在 2018 開放,現在只剩下兩個多禮拜的時間了。

可以看到 subdomain 已經準備好,但還沒上線 (查 ap-southeast-4 的 NS RR 是直接給 NXDOMAIN):



Amazon DynamoDB 的 Global Tables 推到東京了...

DynamoDBGlobal Tables 可以把 DynamoDB 複製到其他區域,讓各地存取自己的資料:

剛剛看到 AWS 宣佈這個功能展到 ap-northeast-1 (東京) 了:「Amazon DynamoDB Global Tables Now Available in Three Additional Asia Pacific Regions」。

Global tables is now available in the Asia Pacific (Tokyo), Asia Pacific (Seoul), and Asia Pacific (Sydney) Regions.


Amazon MQ 在 ap-northeast-{1,2} 推出了...

Amazon MQap-northeast-{1,2} 推出了,先前自己架的,現在可以直接拿現成的服務了:「Amazon MQ is Now Available in the Asia Pacific (Seoul) and Asia Pacific (Tokyo) regions」。

不過 AWS 上的開發主要還是以 SQS 之類的服務為主,可以避免 scalability 的問題 (另外一種可能是一開始就打定要搬出來,所以選擇 open protocol 的方案)。在這樣的前提下,Amazon MQ 的定位就變成將現有軟體丟上去跑... (而不想自己管 XD)

Amazon EFS 在首爾先開了...

Amazon EFS 其實就是 AWS 提供的雲端版 NFS 或是 CIFS,這對於某些應用來說很好用,尤其效能不是主要考量時,像是從外面買來的商用軟體需要找個空間放資料...

不過沒想到在亞洲第一個開的點居然是首爾 (i.e. ap-northeast-2):「Amazon Elastic File System (Amazon EFS) Available in Asia Pacific (Seoul) Region」。

提到 AWS 的首爾區,台北過去的直線距離雖然比大阪與東京都近,但各家的路由都是從日本繞過去,不然其實首爾的點應該會是台灣的首選... 不曉得北京與上海到首爾的連線情況又是如何,找機會開台機器測試看看。

Linksys 的 WRT54GL

前幾天跟同事聊到 Android 刷機的事情,而最近剛好看到介紹這台無線分享器裡的名機,LinksysWRT54GL:「
The WRT54GL: A 54Mbps router from 2005 still makes millions for Linksys」,第一款被廣泛應用在各種客製化硬體的機器。

取自維基百科的「File:Linksys WRT54G.jpg

從 2005 年開始賣,到現在 2016 年還是繼續在賣,而且這東西支援的無線規格很舊,還比其他的無線分享器貴不少:

Witness the Linksys WRT54GL, the famous wireless router that came out in 2005 and is still for sale. At first glance, there seems to be little reason to buy the WRT54GL in the year 2016. It uses the 802.11g Wi-Fi standard, which has been surpassed by 802.11n and 802.11ac. It delivers data over the crowded 2.4GHz frequency band and is limited to speeds of 54Mbps. You can buy a new router—for less money—and get the benefit of modern standards, expansion into the 5GHz band, and data rates more than 20 times higher.


Despite all that, people still buy the WRT54GL in large enough numbers that Linksys continues to earn millions of dollars per year selling an 11-year-old product without ever changing its specs or design.

量大到 Broadcom 還是繼續支援,然後產品 PM 就抱怨他搞不懂:

"To be honest, it somewhat baffles my mind," Linksys Global Product Manager Vince La Duca told Ars. But production won't stop any time soon as long as Linksys' suppliers, including chipmaker Broadcom, keep selling the parts needed to build the WRT54GL. "We'll keep building it because people keep buying it," La Duca said.
