BiglyBT 支援 BitTorrent v2

先前提到的「libtorrent 宣佈支援 BitTorrent v2」,BiglyBT 整合完了:「BiglyBT is the First Torrent Client to Support the BitTorrent V2 Spec」。

看了一下 BiglyBT 的介紹,主要是因為當初 https://en.wikipedia.org/wiki/Vuze 變成 adware 之後分支出來的:

BiglyBT is a feature filled, open source, ad-free, bittorrent client.

BiglyBT is the continuation of the Vuze/Azureus open source project first created in 2003, and is being actively developed by the original coders.

不過這是 Java 寫的 client,目前需求也不大,我自己應該還是會繼續等 qBittorrent 支援,看起來在這邊:「BitTorrent v2 #13344」,不過現在看起來沒什麼進展...

Onion Service 第二版的退場計畫

Tor 這邊給出了 Onion Service v2 的退場計畫:「Onion Service version 2 deprecation timeline」,關於 v2 與 v3 的差異,可以參考之前寫的「下一代的 Tor Hidden Service」,裡面有提到 v3 的 spec。

v2 與 v3 最大的差異就是本來 v2 的 hostname 是 16 個英數字 (大約是 80-bit security),現在 v3 變成是 56 個英數字 (大約是 280-bit security),大幅降低 collision 的機會。

目前公佈的時間表是在 2020 年九月先拋警告出來,2021 年七月拔掉 server 支援,2021 年十月拔掉 client 支援:

1. September 15th, 2020
0.4.4.x: Tor will start warning onion service operators and clients that v2 is deprecated and will be obsolete in version 0.4.6.

2. July 15th, 2021
0.4.6.x: Tor will no longer support v2 and support will be removed from the code base.

3. October 15th, 2021
We will release new Tor client stable versions for all supported series that will disable v2.

差不多是十五個月的計畫...

Amazon S3 要拿掉 Path-style 存取方式

Hacker News 上翻的時候翻到的公告:「Announcement: Amazon S3 will no longer support path-style API requests starting September 30th, 2020」。

現有的兩種方法,一種是把 bucket name 放在 path (V1),另外一種是把 bucket name 放在 hostname (V2):

Amazon S3 currently supports two request URI styles in all regions: path-style (also known as V1) that includes bucket name in the path of the URI (example: //s3.amazonaws.com/<bucketname>/key), and virtual-hosted style (also known as V2) which uses the bucket name as part of the domain name (example: //<bucketname>.s3.amazonaws.com/key).

這次要淘汰的是 V1 的方式,預定在 2020 年十月停止服務 (服務到九月底):

Customers should update their applications to use the virtual-hosted style request format when making S3 API requests before September 30th, 2020 to avoid any service disruptions. Customers using the AWS SDK can upgrade to the most recent version of the SDK to ensure their applications are using the virtual-hosted style request format.

Virtual-hosted style requests are supported for all S3 endpoints in all AWS regions. S3 will stop accepting requests made using the path-style request format in all regions starting September 30th, 2020. Any requests using the path-style request format made after this time will fail.
