歐盟對 Google 的 24.2 億歐元的罰款確定

從「Google loses challenge against EU antitrust ruling, $2.8-bln fine」這邊看到的，新聞的標題寫的是換算後的美金。

新聞裡提到歐盟主要有三個主題在跟 Google 訴訟，這次確定的是利用搜尋引擎偏好自家的購物比較服務，產生不公平競爭：

Competition Commissioner Margrethe Vestager fined the world's most popular internet search engine in 2017 over the use of its own price comparison shopping service to gain an unfair advantage over smaller European rivals.

另外兩個還在進行的是 Android 與 AdSense：

The company could face defeats in appeals against the other two rulings involving its Android mobile operating system and AdSense advertising service, where the EU has stronger arguments, antitrust specialists say.

應該是還有個 YouTube 才對，不過印象中主要是版權相關的問題，跟 antitrust 這邊的關係好像少了一些...

eBay 把 MongoDB 當 cache layer 的用法...

在「How eBay’s Shopping Cart used compression techniques to solve network I/O bottlenecks」這邊 eBay 描述了他們怎麼解決在 MongoDB 上遇到的問題，不過我看的是他們怎麼用 MongoDB，而不是這次解決的問題：

It’s easier to think of the MongoDB layer as a “cache” and the Oracle store as the persistent copy. If there’s a cache miss (that is, missing data in MongoDB), the services fall back to recover the data from Oracle and make further downstream calls to recompute the cart.

把 MongoDB 當作 cache layer，當 cache miss 的時候還是會回去底層的 Oracle 撈資料計算，這用法頗有趣的...

不拿 memcached 出來用的原因不知道是為什麼，是要找個有 HA 方案的 cache layer 嗎？還是有針對 JSON document 做判斷操作？

電視節目上表演從 Amazon Echo 買東西...

然後觀眾家裡的 Amazon Echo 就跟著買了 XDDD：「TV anchor says live on-air 'Alexa, order me a dollhouse' – guess what happens next」。

A San Diego TV station sparked complaints this week – after an on-air report about a girl who ordered a dollhouse via her parents' Amazon Echo caused Echoes in viewers' homes to also attempt to order dollhouses.
