Bruce Schneier 提到了最近幾個剛好相關的議題,關於機器學習在情色產業使用時遇到的隱私議題:「Technology to Out Sex Workers」。

第一個提到的是 PornHub 用機器學習辨識演員以及各種「其他資訊」,這邊引用的報導是 TechCrunch 的「PornHub uses computer vision to ID actors, acts in its videos」:

PornHub is using machine learning algorithms to identify actors in different videos, so as to better index them.

The computer vision system can identify specific actors in scenes and even identifies various positions and… attributes.


People are worried that it can really identify them, by linking their stage names to their real names.

最後是提到 Facebook 已經有能力這樣做,而且已經發生了:

Facebook somehow managed to link a sex worker's clients under her fake name to her real profile.

Her sex-work identity is not on the social network at all; for it, she uses a different email address, a different phone number, and a different name. Yet earlier this year, looking at Facebook’s “People You May Know” recommendations, Leila (a name I’m using using in place of either of the names she uses) was shocked to see some of her regular sex-work clients.

這個議題與 Mass surveillance 有點像...。

用 SAWS 管理 AWS 資源

看開發記錄,應該很久了... 這次是 donnemartin/saws

Python 寫的,所以用 pip 就可以跑,不過目前還是不支援 profile:

Command line options for starting SAWS with a specific profile are under development.

所以自己用還可以 (因為只有一個帳號),公司有一堆帳號得切來切去就沒辦法了,先丟著...

EC2 的 IAM Role 可以動態改了...

EC2IAM Role 根本是開發階段最常重新啟動的理由之一 XDDD

AWS 總算把動態調整 IAM Role 的功能給做出來了:「New! Attach an AWS IAM Role to an Existing Amazon EC2 Instance by Using the AWS CLI」。

不過看到文章完全沒有截圖,心裡大概就猜得到目前 web console 還不支援了... 現在只能透過 command line 操作,像是「Attach the IAM role to an existing EC2 instance that was originally launched without an IAM role」這一段:

$ aws ec2 associate-iam-instance-profile --instance-id YourInstanceId --iam-instance-profile Name=YourNewRole-Instance-Profile

或是「Replace the attached IAM role」這段:

$ aws ec2 replace-iam-instance-profile-association --association-id YourCurrentAssociation-id --iam-instance-profile Name=YourReplacementRole-Instance-Profile

不過有進度總是比沒進度開心,這功能應該會加到 web console...

Stack Overflow 做的 Developer Survey 2016

Stack Overflow 對開發者發問卷後把結果整理出來了:「Stack Overflow Developer Survey 2016 Results」,約 56k 個樣本數:

This year, 56,033 coders in 173 countries answered the call.

整個問卷分成五塊區域:Overview、Developer Profile、Technology、Work、Community,其中 Overview 的部份是給時間不多的人看的,整理了一些比較特別或是有趣的重點:

Most developers prefer dogs to cats. (But not developers in Germany.)



Surveys aren’t perfect. While our large sample size helps offset some biases, it’s still biased against devs who don't speak English, or who don't like taking English-language surveys.

另外是有女性對這份問卷表示不滿:「Stack Overflow’s developer survey analysis hurts women」,尤其是 Stack Overflow 標示了只有 5.8% 的女性,這會導致女性樣本數在答案細分族群時的統計偏差的問題會很嚴重。

另外這篇文章的作者也對 Stack Overflow 裡的結論很不滿意。


其中 Salary 這段應該是很多人都有動力去讀一讀了解的,裡面還包括了各地區與麥當勞的大麥克指數的相對數值分析,讓你有個參考值可以感覺。
