Mattermost 推出了 ESR 5.31

在「Support for ESR 5.25 is ending」這邊看到 Mattermost 新的 ESR (Extended Support Release) 釋出了,也就是 5.31 版。

不過看了一下發現 support 期間還是很短,一般的 release 是三個月,ESR 也才九個月:

另外一個大問題是在行動平台上多帳號的支援,官方在「Mobile Apps FAQ」有提到這個問題,然後也有解釋技術上的問題,不過從 issue tracking system 可以看到官方對這個 feature 進展不怎麼快:

At the moment, we only support connecting to one server at a time; however, we are aware that this is one of the top feature requests for the mobile app. We are currently investigating some technical challenges, such as how to handle push notifications coming from multiple servers. To follow our progress on this feature, you can join the RN: Multi-Server channel on our community server.


Wikimedia 弄了自己的 Mattermost

Wikimedia (維基百科後面的基金會) 又多了一個溝通工具:「Introducing Wikimedia Chat!」。

最傳統的方式是在 wiki 的 Talk 頁上溝通 (現在看起來還是有些正式的投票討論需要走這個方式),但那個界面用起來真的頗痛苦... 一般的社群討論還是會在其他工具上進行。

先前有晃進去看過的平台應該是 IRC 與 Telegram 群組,不過後來因為量太大就閃出來了,另外這邊有提到 SlackDiscordFacebook

You can now see Wikimedia-related discussion groups in Slack, Discord, Telegram, Facebook, and many more.


Besides being scattered and inaccessible to people who don’t have accounts in those platforms (for privacy reasons for example), these platforms use proprietary and closed-source software, are outside Wikimedia infrastructure and some harvest our personal data for profit.

freenode 上面的 IRC 算是相對起來比較開放,但還是少了不少功能,所以就自己架了 Mattermost 出來:

IRC on is a good alternative but it lacks basic functionalities of a modern chat platform. So we created Wikimedia Chat, a Mattermost instance hosted in Wikimedia Cloud.

比較特別的是超過 90 天的記錄會被砍掉?不太懂這邊的邏輯...

As a Wikimedia Cloud project, all of discussions, private and public are covered by Code of conduct in technical spaces and due to Wikimedia Cloud privacy policy all discussions older than ninety days will be deleted.

架設 MTProxy 加快 Telegram 的速度

在台灣如果是透過 HiNetTelegram 是沒什麼問題 (不需要翻牆),不過連結的 preview 以及圖片影片讀取的速度實在很慢,試著在 GCP (彰濱機房) 跟 Vultr (東京機房) 上架 Proxy 測試看看,發現速度都改善很多...

這邊用的是官方提供的 MTProxy,我把安裝的懶人包放在自己的 wiki 上了:「MTProxy」,在 AWS 或是 GCP 上安裝時,因為網卡拿到的是 Private IP 而非對外的 Public IP,需要指定 --nat-info 告訴 MTProxy 要針對協定裡面的 IP address 另外處理。


Slack 丟出 S-1 要 IPO...

最近一波 IPO 潮,現在輪到了 Slack

Form S-! 的資料可以在「slacks-1.htm」這邊抓到,裡面有些數字可以看看,懶的看的話可以看 TechCrunch 的整理:「Slack files to go public, reports $138.9M in losses on revenue of $400.6M」。

算是相當快的,2013 年八月到現在還不到六年...

PHP 的 BotMan

看到「PHP BotMan」這個專案 (A framework agnostic PHP library to build chat bots),把各家 IM 工具都串起來讓你直接接上去用,在 initialize 完後,就可以這樣寫:

$botman->hears('keyword', function(BotMan $bot) {
    // do something to respond to message
    $bot->reply('You used a keyword!');


$botman->fallback(function(BotMan $bot) {
    return $bot->reply('Sorry I do not know this command');

把事情專注在 bot 邏輯本身,不需要去管怎麼跟 Facebook 或是 Slack 接的細節...

Slack 的 User Groups 功能

Slack 最近除了推出了 Group Messages 以外 (參考「Slack 支援多人討論群組」),也推出了 User Groups 的功能給付費用戶使用:「Introducing User Groups」:

User Groups are enabled for all Slack teams on paid plans (both Standard and Plus). New groups can be created in the Team Directory panel in your desktop app. You can give each a descriptive name and add a note on purpose to help others understand what each group is for. The team directory will then list your team’s existing user groups and show the details of each, along with the the group’s members.

使用者可以被分類成 Group,然後可以針對某一個 Group 傳訊息。而 Plus Plan 的用戶可以透過 SSO 機制將群組資訊帶進來用:

For teams using Single Sign On (SSO) on the Plus plan, you can even use groups to control provisioning accounts from your SSO tools. Users of Active Directory in OneLogin, PingOne, PingFederate, or Okta can take advantage of this built-in user provisioning support to add employees automatically into Slack User Groups matching each employee’s existing group rights, roles and permissions in your internal directory.

另外也有提供 API 讓你用,所以 Standard Plan 用戶也可以自己寫,然後塞進去。

又一個 Open Source 版本的 Slack Clone:Mattermost

在「Open source Slack-alternative reaches 1.0: Self-host ready, Slack-compatible, MIT licensed」這邊看到 Mattermost 這套 Slack clone,而 Mattermost 的標語是:

Mattermost is an open source, on-prem Slack-alternative

後面也是弄了一個團隊 (Team),有種 GitLab 的感覺...

用 Facebook Chat 當作 VPN tunnel...

在同一天的 Hacker News Daily 上看到這兩篇,這是怎樣 XDDD:

RMS 對 Facebook 的意見就不提了,來討論後面這個專案:

The idea of this project is to tunnel Internet traffic through Facebook chat (packets are sent as base64), the main component is tuntap and also the Google's Gumbo parser which does the interaction with Facebook (login, send/receive messages, etc.).

用 C++ 寫的... 不過 Facebook 可以通的環境通常可以有其他的 VPN 選擇吧 @_@
