AlphaGo 的開局庫分析

Facebook 上看到 Aja Huang 的訊息,介紹了 DeepMind 放出的新資料,由 AlphaGo 分析人類開局的各種勝率 (不是先前發表出來更凶的 AlphaZero,但不曉得是 AlphaGo Zero 還是 AlphaGo Master...)。

網站在 AlphaGo Teach: Discover new and creative ways of playing Go,盤面上的數字都是指黑棋勝率。

This tool provides analysis of 6,000 of the most popular opening sequences from the recent history of Go, using data from 231,000 human games and 75 games AlphaGo played against human players.

Explore the board and learn how AlphaGo's moves compare to those of professional and amateur players.

由於這是暴力法算出超大量的開局資料,而且是完整公佈在網路上,可以預料接下來的職業比賽,開局應該會參考這邊的資料進行修正...

直接從 IMDb 編號看影片

看到「Now Anyone Can Embed a Pirate Movie in a Website」這邊介紹的東西,直接輸入 IMDb 的編號 (包括 tt 開頭的那串編號),他就自動拉出 embed code:

然後可以直接線上觀看:

然後還支援字幕 (唔):

Interestingly, should one of those sources be Google Video, Vodlocker says its player offers Chromecast and subtitle support.

官網有寫來源是到處找:

VoDLocker searches all general video hosters like youtube, google drive, openload...

看起來整塊技術其實都是現成的。透過 search engine 加上定期的檢查機制與回報機制就可以做完 @_@

Adobe 居然決定加碼投入資源更新 Linux 上 NPAPI 版的 Flash (也就是舊版 API)

在「Beta News – Flash Player NPAPI for Linux」這邊看到 Adobe 要投入資源處理 LinuxNPAPI 版的 Flash Player...

先前 Linux 下是 NPAPI 與 PPAPI 兩個版本都有 Flash Player,但是 NPAPI 維持在 11.2,只做安全性更新:

Linux users have access to both NPAPI and PPAPI versions of Flash Player. However, for the last four years, the NPAPI version has been held at 11.2 and regularly updated with only security fixes while the PPAPI version (used in Chrome and Chromium based browsers), is in line with the standard Windows and Mac releases.

然後決定加碼讓兩邊同步:

Today we are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23). We have done this significant change to improve security and provide additional mitigation to the Linux community.

Flash Player 你趕快退場啊啊啊...

Mozilla 的 Shumway 登陸 Firefox Nightly Channel

MozillaShumway 專案是用 JavaScript 實作的 Flash Player,算是把 Flash Plugin 淘汰掉的方案:

Shumway is an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance.

由於是跑在 JavaScript 內,安全性受到 SpiderMonkey 的 Sandbox 保護,相較於 Adobe 常常出 security update 讓人有點頭痛...

最近 Shumway 的大進展是在 Firefox Nightly Channel 啟用了部份網站,可以測試 Amazon.com 上的影片:「Firefox Nightly now plays Amazon.com Flash videos using Shumway」。

不知道有沒有機會 porting 到 Google Chrome 上面...
