我習慣在通勤或是睡前刷一下手機，看一下各類媒體有什麼資訊 (參考「為什麼我還繼續用 RSS (Feed)」這邊，是我找「未知的來源」的一部分)，但這麼一來會遇到幾個問題：
前陣子有些朋友問到為什麼 Twitter 上會有些明顯跟我的意見不同的 tweet，原因就是這樣啦...
而在昨天，Twitter 推出了 Full-archive search API：「Introducing the premium full-archive search endpoint」，從 Rate limit 就可以看出來對 Enterprise 不夠用，但對 Startup 應該有機會使用：
台灣用 Twitter 的量偏低，也許對專注在台灣的應用來說還好，但對國外的單位來說應該是多了不少變化可以玩...
在上一篇提到的「控制瀏覽器裡的 Web API」，用了一兩天後有遇到一些問題，大概整理一下...
mail.google.com列入白名單 (一個阻擋條件都不能設)，這是因為遇到瀏覽器的 bug，在「General breakage on specific site · Issue #55 · snyderp/web-api-manager」這邊作者有找到問題，他判斷是瀏覽器的問題後開了 ticket 給 Firefox 與 Chrome，不知道什麼時候會好...
www.google.com.tw，看你用的網域) 另外開一組設定管理，另外一個是直接把 WebGL Specification 的阻擋關掉。
The PostgreSQL Global Development Group is pleased to announce the launch of the official community Twitter handle: https://twitter.com/postgresql
@postgresql will contain a mix of automatic and manually curated postings from a group of volunteers that feature various aspects of PostgreSQL and the community-at-large. Content will contain a mix of news, advice, and highlights around PostgreSQL, and enable the PostgreSQL Global Development Group to further engage with the community. If you would like for @postgresql to highlight PostgreSQL-oriented content, we encourage you to reach out to @postgresql via Twitter’s direct message feature.
本來的 Planet PostgreSQL 也會繼續服務：
The live feed for blog entries syndicated from Planet PostgreSQL will continue to be available at https://twitter.com/planetpostgres
還是繼續用 RSS 訂閱就好 XD
在「The rates of traffic flow on different kinds of 4-way intersections」這邊看到有趣的東西，利用遊戲 Cities: Skylines 模擬各種道路設計對流量的影響：
This is an animation of traffic flows simulated on 30 different kinds of four-way junctions, from two roads intersecting with no traffic lights or signs to complex stacked interchanges that feature very few interactions between individual cars. It was recorded in a game called Cities: Skylines, a more realistic take on SimCity.
然後裡面有看到很多常見的設計，還有一些沒看過的神奇設計 XD 另外有些設計超級複雜，第一次開的人真的會知道怎麼開嗎 XDDD
之前看到「Hard Questions: Is Spending Time on Social Media Bad for Us?」這篇，一直不知道要怎麼吐槽... 然後看到 Twitter 上的這則 tweet XDDD
Facebook staff scientist says people are unhappy on Facebook because they’re not posting enough. But there’s a cure! The cure is post more on Facebook. https://t.co/vZMkNpnZvN pic.twitter.com/SIvN8knahz

We’re rolling out an update to login verification.
You’ll now be able to use a third party app for two-factor authentication instead of SMS text messages.https://t.co/UXl3xKLEaG

在上面的「How to use login verification」連結可以看到 HOTP 的設定方式：
Vireo is a lightweight and versatile video processing library that powers our video transcoding service, deep learning recognition systems and more. It is written in C++11 and built with functional programming principles. It also optionally comes with Scala wrappers that enable us to build scalable video processing applications within our backend services.
在 Tools 的部份也可以看到很多功能，像是：
thumbnails: extracts keyframes from the input video and saves them as JPG images
viddiff: checks if two video files are functionally identical or not (does not compare data that does not affect the playback behavior)
另外要注意的是，預設不會將 GPL 的套件納入編譯，需要指定
The following libraries are disabled by default. To enable GPL licensed components, they have to be present in your system and --enable-gpl flag have to be explicitly passed to
看起來主要就是最常見的那包... (libavformat / libavcodec / libavutil / libswscale / libx264)
TechCrunch 上看到的，俄羅斯政府不只在美國選舉時這樣做，同時也在英國脫歐公投的議題上進行操作：「Twitter says Russians spent ~$1k on six Brexit-related ads」。
In response to the Commission’s request for information concerning Russian-funded campaign activity conducted during the regulated period for the June 2016 EU Referendum (15 April to 23 June 2016), Twitter reviewed referendum-related advertising on our platform during the relevant time period.
Among the accounts that we have previously identified as likely funded from Russian sources, we have thus far identified one account—@RT_com— which promoted referendum-related content during the regulated period. $1,031.99 was spent on six referendum-related ads during the regulated period.
With regard to future activity by Russian-funded accounts, on 26 October 2017, Twitter announced that it would no longer accept advertisements from RT and Sputnik and will donate the $1.9 million that RT had spent globally on advertising on Twitter to academic research into elections and civil engagement. That decision was based on a retrospective review that we initiated in the aftermath of the 2016 U.S. Presidential Elections and following the U.S. intelligence community’s conclusion that both RT and Sputnik have attempted to interfere with the election on behalf of the Russian government. Accordingly, @RT_com will not be eligible to use Twitter’s promoted products in the future.
在「140 Vs. 280: Users Engage With Longer Tweets Data Shows」這邊分析了在 Twitter 上 0～140 與 141～280 字的 tweet 所帶來的互動差異：
可以看到較長的 tweet 會有比較多的 retweet 與 like，不過更細一步的分析就沒有了... 文章內也有提到資料的分析是怎麼來的：
The data parameters: 30,000 publisher tweets that included links between November 29 – December 6.
The results: The click-through rate was roughly equal for both tweet length types but overall engagement nearly doubled for longer tweets. On tweets containing 141-280 characters, the average retweet was a staggering 26.52% – compared the 13.71% for tweets with 0-140 characters. For likes, tweets containing 141-280 characters had an average of a whopping 50.28%, compared to 0-140’s 26.96%.
