紐約市也將禁止雇主詢問薪資

去年麻州立法禁止雇主詢問前工作的薪資 (參考「麻州立法禁止詢問前一份工作的薪資」),而紐約市也要加入這個行列了:「New York City bans employers from asking potential workers about their past salary」。

New York City joined Massachusetts, Puerto Rico, and Philadelphia in banning employers from asking job applicants about their pay at current or past jobs after the city council passed the measure in a vote on Wednesday.

Adblock 與 Paywall 帶來的影響

這邊探討了新聞網站引入 Adblock 反制與 Paywall 帶來的影響:「Sites that block adblockers seem to be suffering」。

作者拿了 WIREDBild (Axel Springer)、ForbesCity AM 以及 Washington PostAlexa 數字來歸納,可以看出新聞網站的取代率太高 (甚至看不到就算了),可以看到 bounce rate 大幅增加 (很多人發現不能看就不會繼續看下去),而且 pageview 也大幅下降。

不過文章還是很粗糙,有太多變數沒有考慮進去...

舊金山要求新的建築物都必須有太陽能設備

舊金山通過在 2017 年之後的建築物必須有 15% 的屋頂面積必須是太陽能相關的設備:「San Francisco Is Requiring Solar Panels on All New Buildings」:

The ordinance, passed unanimously by the city’s Board of Supervisors, extends an existing California law which requires 15 percent of roof space on new buildings to be “solar ready” — available and unshaded. That ordinance applies to residential or commercial buildings 10 stories or shorter.

也就是說,可以是太陽能的發電,也可以是太陽能集熱的設備:

Under the new ordinance, which will go into effect in 2017, new buildings need to have solar energy of some kind installed, either electricity-generating panels or solar heating units.

希望在 2020 年達到 100% 再生能源的目標:

San Francisco took a major step toward its own goal of meeting the city’s electricity demands with 100 percent renewable energy by 2020.

這成為美國第一個主要城市通過這樣的規範:

This week, San Francisco became the first major U.S. city to require all new buildings to have solar panels on their roofs, according to Scott Wiener, the city supervisor who introduced the bill.

Airbnb 被抓到操作站上資料以美化數據

在「How Airbnb's Data hid the Facts in New York City」這篇文章裡提到了 Airbnb 在去年 (2015 年) 十一月時操作站上資料,美化數據的證據。

Airbnb 在 2015 年 12 月時發表了一篇「Data on the Airbnb Community in NYC」,說明 Airbnb 對紐約地區的貢獻的種種之類的 PR 文章。

Airbnb 的文章裡面提到了資料是取自 2015 年 11 月 17 日的資料:

As of November 17, 2015 there were 35,966 active Airbnb listings in New York.

而作者則發現了 2015 年 11 月 17 日當天,Airbnb 站上的資料被「清理」過:

A major part of Airbnb's recent data release was a snapshot of New York City listings as of November 17, 2015. This report shows that the snapshot was photoshopped: in the days leading up to November 17, Airbnb ensured a flattering picture by carrying out a one-time targeted purge of more than 1,000 listings. The company then presented November 17 as a typical day in the company’s operations and mis-represented the one-time purge as a historical trend.

而且只針對紐約地區清理:

No similar event took place in other cities in North America or elsewhere.
