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.
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.
用 C++ 寫的，另外也已經提供 Scala 的接口，這應該是讓 Twitter 的人可以方便使用：
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)
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.
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%.
According to a Facebook spokesperson, Facebook workers will have to review full, uncensored versions of nude images first, volunteered by the user, to determine if malicious posts by other users qualify as revenge porn.
