The fastest open source CPU ever, Facebook shares AI algorithms fighting harmful content, and more news
|
||||
======
|
||||
Catch up on the biggest open source headlines from the past two weeks.
|
||||
![Weekly news roundup with TV][1]
|
||||
|
||||
In this edition of our open source news roundup, we share Facebook's choice to open source two algorithms for finding harmful content, Apple's new role in the Data Transfer Project, and more news you should know.
|
||||
|
||||
### Facebook open sources algorithms used to find harmful content
|
||||
|
||||
Facebook announced that it has [open sourced two algorithms][2] used to find child exploitation, threats of terrorism, and graphic violence on the platform. In a blog post on August 1st, Facebook shared that PDQ and TMK+PDQF–two technologies that store files as digital hashes, then compare them with known examples of harmful content–are [now live on GitHub][3].
|
||||
|
||||
The code release comes amidst increased pressure to get harmful content off the platform as soon as possible. After March's mass murder in New Zealand was streamed on Facebook Live, the Australian government [threatened Facebook execs with fines and jail time][4] if the video wasn't promptly removed. By releasing the source code for these algorithms, Facebook said that it hopes nonprofits, tech companies, and solo developers can all help them find and remove harmful content faster.
|
||||
|
||||
### Alibaba launches the fastest open source CPU
|
||||
|
||||
Pingtouge Semiconductor - an Alibaba subsidiary - [announced its Xuantie 91 processor][5] last month. It's equipped to manage infrastructure for AI, the IoT, 5G, and autonomous vehicles, among other projects. It boasts a a 7.1 Coremark/MHz, making it the fastest open source CPU on the market.
|
||||
|
||||
Pintogue announced plans to make its polished code available on GitHub this September. Analysts view this release as a power move to help China hit its goal of using local suppliers to meet 40 percent of processor demand by 2021. Recent tariffs on behalf of the U.S. threaten to derail this goal, creating the need for open source computer components.
|
||||
|
||||
### Mattermost makes the case for open source collaboration apps
|
||||
|
||||
All open source communities benefit from one or more places to communicate with each other. The world of team chat apps seems dominated by minimal, mighty tools like Slack and Microsoft Teams. Most options are cloud-based and proprietary; Mattermost takes a different approach by selling the value of open source collaboration apps.
|
||||
|
||||
> “People want an open-source alternative because they need the trust, the flexibility and the innovation that only open source is able to deliver,” said Ian Tien, co-founder and CEO of Mattermost.
|
||||
|
||||
With clients that range from Uber to the Department of Defense, Mattermost cornered a crucial market: Teams that want open source software they can trust and install on their own servers. For businesses that need collaboration apps to run on their internal infrastructure, Mattermost fills a gap that [Atlassian left bare][6]. In an article for Computerworld, Matthew Finnegan [explores][7] why on-premises, open source chat tools aren't dead yet.
|
||||
|
||||
### Apple joins the open source Data Transfer Project
|
||||
|
||||
Google, Facebook, Twitter, and Microsoft united last year to create the Data Transfer Project (DTP). Hailed as a way to boost data security and user agency over their own data, the DTP is a rare show of solidarity in tech. This week, Apple announced that they'll [join the fold][8].
|
||||
|
||||
The DTP's goal is to help users transfer their data from one online service to another via an open source platform. DTP aims to take out the middleman by using APIs and authorization tools to let users transfer their data from one service to another. This would erase the need for users to download their data, then upload it to another service. Apple's choice to join the DTP will allow users to transfer data in and out of iCloud, and could be a big win for privacy advocates.

开源新闻综述：有史以来最快的开源 CPU、Facebook 分享对抗有害内容的 AI 算法
|
||||
======
|
||||
|
||||
> 不要错过最近两周最大的开源新闻。
|
||||
|
||||
![Weekly news roundup with TV][1]
|
||||
|
||||
在本期开源新闻综述中，我们分享了 Facebook 开源了两种算法来查找有害内容，Apple 在数据传输项目中的新角色以及你应该知道的更多新闻。
|
||||
|
||||
### Facebook 开源算法用于查找有害内容
|
||||
|
||||
Facebook 宣布它[开源两种算法][2]用于在该平台上发现儿童剥削、恐怖主义威胁和写实暴力。在 8 月 1 日的博客文章中，Facebook 分享了 PDQ 和 TMK + PDQF 这两种将文件存储为数字哈希的技术，然后将它们与已知的有害内容示例进行比较 - [现在已放在 GitHub 上][3]。
|
||||
|
||||
该代码是在 Facebook 要尽快将有害内容从平台上移除的压力之下发布的。三月份在新西兰的大规模谋杀案被曝光在 Facebook Live 上，澳大利亚政府[威胁][4]如果视频没有及时删除 Facebook 高管将被处以罚款和入狱。通过发布这些算法的源代码，Facebook 表示希望非营利组织、科技公司和独立开发人员都能帮助他们更快地找到并删除有害内容。
|
||||
|
||||
### 阿里巴巴发布了最快的开源 CPU
|
||||
|
||||
上个月，阿里巴巴的子公司平头哥半导体公司[发布了其玄铁 91 处理器][5]。它可以用于人工智能、物联网、5G 和自动驾驶汽车等基础设施。它拥有 7.1 Coremark/MHz 的基准，使其成为市场上最快的开源 CPU。
|
||||
|
||||
平头哥宣布计划在今年 9 月在 GitHub 上提供其优质代码。分析师认为此次发布旨在帮助中国实现其目标，即到 2021 年使用本地供应商满足 40％ 的处理器需求。近期美国的关税调整威胁要破坏这一目标，从而造成了对开源计算机组件的需求。
|
||||
|
||||
### Mattermost 为开源协作应用提供了理由
|
||||
|
||||
所有开源社区都受益于可以从一个或多个地方彼此进行通信。团队聊天应用程序的世界似乎由 Slack 和 Microsoft Teams 等极少数的强大工具主导。大多数选择都是基于云的和专有产品的；而 Mattermost 采用了不同的方法，销售开源协作应用程序的价值。
|
||||
|
||||
“人们想要一个开源替代品，因为他们需要信任、灵活性和只有开源才能提供的创新，”Mattermost 的联合创始人兼首席执行官 Ian Tien 说。
|
||||
|
||||
随着从优步到国防部的客户，Mattermost 走上了一个关键市场：需要开源软件的团队，他们可以信任这些软件并安装在他们自己的服务器上。对于需要协作应用程序在其内部基础架构上运行的企业，Mattermost 填补了 [Atlassian 离开后][6] 的空白。在 Computerworld 的一篇文章中，Matthew Finnegan [探讨][7]了为什么在本地部署的开源聊天工具尚未死亡。
|
||||
|
||||
### Apple 加入了开源数据传输项目
|
||||
|
||||
Google、Facebook、Twitter 和微软去年联合创建了<ruby>数据传输项目<rt>Data Transfer Project</rt></ruby>（DTP）。DTP 被誉为通过自己的数据提升数据安全性和用户代理的一种方式，是一种罕见的技术上的团结展示。本周，Apple 宣布他们也将[加入][8]。
|
||||
|
||||
DTP 的目标是帮助用户通过开源平台将数据从一个在线服务转移到另一个在线服务。DTP 旨在通过使用 API 和授权工具来取消中间人，以便用户将数据从一个服务转移到另一个服务。这将消除用户下载数据然后将其上传到另一个服务的需要。Apple 加入 DTP 的选择将允许用户将数据传入和传出 iCloud，这可能是隐私权拥护者的一大胜利。
