幹壞事是進步最大的原動力
AWS 推出了在直播時就自動上字幕的功能：「Introducing Live Streaming with Automated Multi-Language Subtitling」，其實就是把現有的服務兜出來：「Live Streaming with Automated Multi-Language Subtitling」。
The solution deploys Live Streaming on AWS which includes AWS Elemental MediaLive, MediaPackage, Amazon CloudFront. The solution also deploys AWS Lambda, Amazon Simple Storage Service, Amazon Transcribe, and Amazon Translate.
對於比較沒那麼要求翻譯品質的情況也許可以玩看看...？
Facebook 上的行動電話號碼除了被拿來當作 2FA 的備案外，也被強制分享。更糟的是還被拿來當作廣告的條件：
For years Facebook claimed the adding a phone number for 2FA was only for security. Now it can be searched and there's no way to disable that. pic.twitter.com/zpYhuwADMS

This is so crazy: even if you deliberately don't include your mobile number in your Facebook profile, they'll harvest it when you use it for two-factor authentication, and let advertisers target you with it. https://t.co/0TIr0zsJOt pic.twitter.com/TigHlGR2zF

因為在寫 ansible 的 playbook，有些地方想要偷懶，把檔案放進在 playbook 本身...
網路上搜了一下找到「In YAML, how do I break a string over multiple lines?」這篇，最常用的應該是 |、|- 以及 |+ 了，用這三招塞檔案應該是夠用...
裡面的範例拿 JSON 的格式來解釋還蠻有趣的，代表 JSON 真的很好懂...
Amazon Aurora 推出了兩包玩意，第一包是 Serverless，讓需要人介入的情況更少：「In The Works – Amazon Aurora Serverless」。
在 Serverless 的第一個重點是支援以秒計費：
Today we are launching a preview (sign up now) of Amazon Aurora Serverless. Designed for workloads that are highly variable and subject to rapid change, this new configuration allows you to pay for the database resources you use, on a second-by-second basis.
然後是極為快速的 auto-scaling：
The endpoint is a simple proxy that routes your queries to a rapidly scaled fleet of database resources. This allows your connections to remain intact even as scaling operations take place behind the scenes. Scaling is rapid, with new resources coming online within 5 seconds
這兩個組合起來，讓使用端可以除了在 Amazon EC2 上可以快速 scale 外，後端的資料庫也能 scale 了...
第二個是 Multi-master 架構：「Sign Up for the Preview of Amazon Aurora Multi-Master」。
Amazon Aurora Multi-Master allows you to create multiple read/write master instances across multiple Availability Zones. This enables applications to read and write data to multiple database instances in a cluster, just as you can read across Read Replicas today.
(話說我一直都誤以為 Aurora 是 R/W master...)
Anyway，這個功能不知道怎麼疊上去的... 不笑得會不會有嚴重的 distributed lock issue，反而推薦大家平常都寫到同一台 (像是 PXC 就會這樣)。
新版的 Firefox 已經支援 Multi-processes 架構 (Electrolysis)，但 Ubuntu 上會因為預設值的關係而被關閉，這篇文章就是講原因以及怎麼打開：「Enabling This Makes Firefox More Responsive On Ubuntu」。
由於大家都會裝一堆套件，看起來得用 Force Enable 這邊提到的方法打開，也就是手動在 about:config 內加入 browser.tabs.remote.force-enable，並設為 true。
Firefox 的轉換還有很長一段時間要走...
然後錢就...：「After years of warnings, mobile network hackers exploit SS7 flaws to drain bank accounts」。
O2-Telefonica in Germany has confirmed to Süddeutsche Zeitung that some of its customers have had their bank accounts drained using a two-stage attack that exploits SS7.
Mozilla 說明了 Multi-Process 最近的一些進度：「Update on Multi-Process Firefox」。
就目前測試的資料看起來，速度大幅提昇：
Those users have been enjoying the 400% increase in responsiveness and a 700% improvement when web pages are loading.
現在的 Firefox 是 50 版，目前的情況是當 extension 標成 multi-process compatible 就會啟用：
With Firefox 49 we deployed multi-process Firefox to users with a select set of well tested extensions. Our measurements and user feedback were all positive and so with Firefox 50 we deployed multi-process Firefox to users with a broader set of extensions, those whose authors have marked them as multi-process compatible.
下一個版本 (51) 則是會全面開啟，除非有 extension 標成 multi-process incompatible：
Beyond Firefox 50, we have more work to do to enable multi-process Firefox for users with as yet unsupported extensions. In Firefox 51, if all testing goes according to plan, we’ll be enabling multi-process Firefox for users with extensions that are not explicitly marked as incompatible with multi-process Firefox.
總算要把整個架構換過去了...
看到「Multitouch gestures with libinput dirver on X11, Linux」這個專案，可以在 Linux/X11 下偵測到多點觸控，然後設定對應的按鍵，從他的設定檔就可以看到這套軟體的功能了：
swipe:
3:
left:
shortcut: 'alt+Right'
right:
shortcut: 'alt+Left'
up:
shortcut: 'ctrl+t'
down:
shortcut: 'ctrl+w'
4:
left:
shortcut: 'super+Right'
right:
shortcut: 'super+Left'
up:
shortcut: 'super+a'
down:
shortcut: 'super+s'
pinch:
in:
shortcut: 'ctrl+plus'
out:
shortcut: 'ctrl+minus'不知道實際跑起來如何 @_@
昨天跟朋友吃飯的時候談到這個問題，回家幫他找一下解法。主要的限制是各 ISP 對單一 mac address 限制分配一個 IP，所以問題只在於要怎麼在 Linux 下的單一網卡建立多個不同的 mac address，後續的就好做了。
主要是參考 Macvlan and IPvlan basics 這篇文章的指令測試。
首先是建立 fakevlan1 (卡號系統會隨機產生)，然後啟用他，最後呼叫 dhclient 請 ISP 提供 IP：
# ip link add fakevlan1 link eth1 type macvlan mode bridge # ifconfig fakevlan1 up # dhclient fakevlan1
這邊細部沒有處理 routing 的問題 (dhclient 會收到 ISP 提供的各種 routing 與 dns 資訊)，看起來可以透過「Can I prevent a default route being added when bringing up an interface?」這邊的方法處理掉。
PPPoE 的方法我相信也類似啦... (手邊沒有 HiNet 線路可以測試 XD)
Firefox 的 Multi-process，也就是 Electrolysis，正式進入 Release 版了：「What’s Next for Multi-process Firefox」。
依照說明，會分成這幾個不同種類的 process：
Electrolysis child processes are currently in use for the following tasks within Firefox:
- Legacy NPAPI plugin hosting
- Media playback
- Web content ('content processes')
Mozilla 給的這張圖則是 UI 與 Web Content 分離：
目前是設計成只有 1% 使用者會啟動，而如果你想要測試的話可以用 about:config 修改 browser.tabs.remote.autostart。不過只要有 extension 掛著，就不會啟動，像是這樣：
當我把 extension 全部關閉後：
所以短時間內應該也沒辦法測...
