Amazon RDS 的 RI 也支援彈性計價了

AWS 宣佈 RDS 的 RI 也支援彈性計價了:「Amazon RDS Reserved Instances Offer Instance Size Flexibility」。

也就是說跟 EC2 的 RI 方式切齊,買 db.m4.2xlarge 的 RI 後,可以用在兩台 db.m4.xlarge 上:

For example, let’s say you purchased a db.m4.2xlarge MySQL RI in US East (N. Virginia). The discounted rate of this RI can automatically apply to 2 db.m4.xlarge MySQL instances without you needing to do anything.

包括了相當多種類的 RDS,主要是沒有 license fee 的類型都包括在內了:

Amazon RDS Reserved Instance size flexibility is offered in all regions for the MySQL, MariaDB, PostgreSQL, and Amazon Aurora database engines, as well as the “bring your own license” (BYOL) edition of the Oracle database engine. To learn more about flexible RIs, please visit the Amazon RDS Reserved Instances Page.

但不包括要另外收 license fee 的 SQL Server 與 Oracle LI edition:

Size flexibility does not apply to Microsoft SQL Server and the License Included (LI) edition of Oracle.

Uber 在倫敦將會被停業

Uber 在倫敦將會被停業:「Uber has license to operate in London revoked」、「London regulator announces Uber ban」、「Uber London loses licence to operate」。

更精確的說是不再續發 license,舊的 license 只到 9/30:

Transport for London (TfL), which operates public transport in the capital, has made the decision not to renew the app-based taxi’s license in the city.

The license was renewed in May, but for a period of only five months. It will run out on 30th September, though the company will be allowed to continue to operate during the appeal process.

看起來主要原因是圍繞於 Greyball (利用演算法躲避執法人員的工具):

According to the TfL regulatory board, the ‘approach and conduct’ of Uber showed a lack of corporate responsibility, which could have resulted in public safety and security issues. It also raised concerns with the company’s ‘approach to explaining the use of Greyball, software that could be used to block regulatory bodies from gaining full access to the app.’

新任 CEO 則是出來道歉:「Uber CEO apologizes for “mistakes” in London」。

其實是利益團體之間的衝突... 這戲還在繼續演。

Facebook 決定修改原先的授權條款

Facebook 在各個單位的砲火下決定將本來的 BSD+Patents 授權改為 MIT license:「Relicensing React, Jest, Flow, and Immutable.js」。

Next week, we are going to relicense our open source projects React, Jest, Flow, and Immutable.js under the MIT license.

後面講了很多場面話,聽聽就好... 改成 MIT license 最大的理由應該還是在 PR 面的傷害。

Matt Mullenweg 決定對 React 的專利議題投下反對票

React 的專利問題繼續燒... (可以參考「React 的專利授權議題」,不過陸陸續續還有發生一些事情沒寫...)

Facebook 表態他們不會修改 React 的條款後,Matt Mullenweg (WordPress 的共同創造人,以及 WordPress.com 現在的老大) 直接宣佈了 Gutenberg (WordPress 新的 editor) 將全面停用 React 改用新的 library 開發:

[...] I'm here to say that the Gutenberg team is going to take a step back and rewrite Gutenberg using a different library. It will likely delay Gutenberg at least a few weeks, and may push the release into next year.

算是相當大的一個決策改變...

這件事情剛好讓人想到當年 MovableType 因為 license 問題而失勢 (而讓 WordPress 長起來),究竟 React 會不會逐漸被取代呢...

React 的專利授權議題

ASF (Apache Software Foundation) 全面禁止 Facebook 的 BSD+PATENTS 後 (「Apache Foundation 宣佈禁止使用 Facebook BSD+Patents 的軟體」),整件事情開始熱起來了...

簡單來說,Facebook 有意為之,而且不打算撤回這個有攻擊性的授權模式,參考「Explaining React's license」這邊官方的說明以及有人寫了一篇解讀:「If you’re a startup, you should not use React (reflecting on the BSD + patents license)」。

Facebook 內的意見其實也不一樣,像是 Yarn 之所以沒有 PATENTS 是因為爭取出來的:

接下來應該會有更多爭議討論了...

Apache Foundation 宣佈禁止使用 Facebook BSD+Patents 的軟體

在「RocksDB Integrations」這邊討論到 RocksDBFacebook 所使用的 Facebook BSD+Patents License。

不過因為 RocksDB 最近在換 license (從 Facebook BSD+Patents 換到 Apache License, Version 2.0),移除了 PATENTS 內的限制,需要看 PATENTS 的舊檔案可以在 PATENTS 這邊看到。

Chris Mattmann 正式發出決議禁用 Facebook BSD+Patents License。(參考最後)

另外也提到了 Facebook 是故意埋下這些限制:

Note also Roy's comment that he has discussed the matter with FB's counsel and the word is that the FB license is intentionally incompatible. It is hard to make the argument that it is compatible after hearing that. Pragmatically speaking, regardless of any semantic shaving being done, having a statement like that from the source of the license is very daunting. If they think it is incompatible, we need to not try to wheedle and convince ourselves it is not.

這個 license 之後應該會有更多挑戰...

Hi,

As some of you may know, recently the Facebook BSD+patents license has been
moved to Category X (https://www.apache.org/legal/resolved#category-x).
Please see LEGAL-303 [1] for a discussion of this. The license is also referred
to as the ROCKSDB license, even though Facebook BSD+patents is its more
industry standard name.

This has impacted some projects, to date based on LEGAL-303
and the detective work of Todd Lipcon:

Samza, Flink, Marmotta, Kafka and Bahir

(perhaps more)

Please take notice of the following policy:

o No new project, sub-project or codebase, which has not
  used Facebook BSD+patents licensed jars (or similar), are allowed to use
  them. In other words, if you haven't been using them, you
  aren't allowed to start. It is Cat-X.

o If you have been using it, and have done so in a *release*,
  you have a temporary exclusion from the Cat-X classification thru
  August 31, 2017. At that point in time, ANY and ALL usage
  of these Facebook BSD+patents licensed artifacts are DISALLOWED. You must
  either find a suitably licensed replacement, or do without.
  There will be NO exceptions.

o Any situation not covered by the above is an implicit
  DISALLOWAL of usage.

Also please note that in the 2nd situation (where a temporary
exclusion has been granted), you MUST ensure that NOTICE explicitly
notifies the end-user that a Facebook BSD+patents licensed artifact exists. They
may not be aware of it up to now, and that MUST be addressed.

If there are any questions, please ask on the legal-discuss@a.o
list.

Thanks.

Cheers,
Chris Mattmann

美國聯邦法院認定 Open Source License 是有效的強制性合約

這是是韓國廠商 Hancom 在加州被告上法院:「A federal court has ruled that an open-source license is an enforceable contract」。

But after it began using Ghostscript in its software in 2013, Hancom did neither: it did not open-source its software, and it did not pay Artifex a licensing fee.

At the end of 2016, Artifex filed a lawsuit against Hancom in the US District Court for the Northern District of California.

Hancom 的理由是授權 (license) 不是合約 (contract):

That happened when Hancom issued a motion to dismiss the case on the grounds that the company didn’t sign anything, so the license wasn’t a real contract.

而法官認定 GPL 是合約的一種:

“Not so,” said Judge Jacqueline Scott Corley in her order on the motion on April 25. Corley said the GNU GPL “provides that the Ghostscript user agrees to its terms if the user does not obtain a commercial license. Plaintiff alleges that Defendant used Ghostscript, did not obtain a commercial license, and represented publicly that its use of Ghostscript was licensed under the [GNU GPL]. These allegations sufficiently plead the existence of a contract.”

MP3 專利全數過期

看到有人提到,查了維基百科上面的 MP3 條目,看起來在 4/16 就全部都過期了:

The basic MP3 decoding and encoding technology is patent-free in the European Union, all patents having expired there by 2012 at the latest. In the United States, the technology became substantially patent-free on 16 April 2017 (see below).

If the longest-running patent mentioned in the aforementioned references is taken as a measure, then the MP3 technology became patent-free in the United States on 16 April 2017 when U.S. Patent 6,009,399, held by and administered by Technicolor, expired.

The three exceptions are: U.S. Patent 5,878,080, expired February 2017; U.S. Patent 5,850,456, expired February 2017; and U.S. Patent 5,960,037, expired 9 April 2017.

算是可喜可賀?

完全分散式的 BitTorrent 搜尋引擎

BitTorrent 已經有足夠的技術與環境 (ecosystem) 做出完全分散式架構的搜尋引擎了,類似於 eDonkey Network (或是說後來變成主流的 eMule) 上的 search 功能,但一直沒看到類似的東西...

magnetico 算是一個嘗試,完全透過 DHT 搜尋取得結果:

不過這套軟體的 license 是攻擊性超強的 AGPLv3,算是實驗性質吧。要真正普及應該要像 eMule 一樣直接做進 client 內...

OpenSSL 將轉為 Apache 2.0 License

OpenSSL 最近打算把原本的 license 換成 Apache License, Version 2.0:「Licensing Update」。

主要的原因是希望相容於現有大多數的 open source project:

OpenSSL Re-licensing to Apache License v. 2.0 To Encourage Broader Use with Other FOSS Projects and Products

但這非常詭異啊,舊的 license 最大的問題就是與 GPLv2 不相容,而預定要換的 AL 2.0 也還是不相容啊,搞屁啊。
