Steam 停止使用 Bitcoin 購買遊戲

Steam 宣佈停止使用 Bitcoin 購買遊戲:「Steam is no longer supporting Bitcoin」。

官方提到的原因是因為交易費用太高 (雖然是讓使用者付):

In the past few months we've seen an increase in the volatility in the value of Bitcoin and a significant increase in the fees to process transactions on the Bitcoin network. For example, transaction fees that are charged to the customer by the Bitcoin network have skyrocketed this year, topping out at close to $20 a transaction last week (compared to roughly $0.20 when we initially enabled Bitcoin).

另外一個原因是波動問題:

Historically, the value of Bitcoin has been volatile, but the degree of volatility has become extreme in the last few months, losing as much as 25% in value over a period of days.

所以這樣推測,Steam 不是直接換成法幣?我記得他們合作的交易所 (BitPay) 可以馬上換成法幣...

去電視廣告的服務又來了...

看到「Plex’s DVR now lets you skip the commercials… by removing them for you」這篇文章,介紹 Plex 要推出去電視廣告的服務...

維基百科上的介紹比較清楚:「Plex (software)」,主要有兩個元件組成,media server 與 player:

  • The Plex Media Server desktop application runs on Windows, macOS and Linux-compatibles including some types of NAS devices. The 'server' desktop application organizes video, audio and photos from your collections and from online services, enabling the players to access and stream the contents.
  • The media players. There are official clients available for mobile devices, smart TVs, and streaming boxes, a web app and Plex Home Theater (no longer maintained), as well as many third-party alternatives.

然後這次要推出的功能是直接在錄影的時候把廣告拿掉:

Plex confirmed it’s rolling out a new feature that will allow cord cutters to skip the commercials in the TV programs recorded using its software, making the company’s lower-cost solution to streaming live TV more compelling. Unlike other commercial-skip options, Plex’s option will remove commercials from recordings automatically.

這讓我有些印像... 當年 TiVo 也有類似的功能,不過文章裡有提到 TiVo 是提供 skip 而非直接拿掉:

The new feature works by locating the commercials in your recorded media. It then actually removes them before the media is stored in your library. That sounds like it could be even better than TiVo’s commercial skipping option, for example, because you don’t have to press a button to skip the ads — they’re being pulled out for you, proactively.

不過主要是認識了 Plex 這個軟體... 如果是電視兒童的話應該用的到 XD 台灣目前的電視節目好像看的比較少...

man 的復活節彩蛋

有人在 Unix & Linux Stack Exchange 上抱怨他的自動化測試在清晨會爛掉,但其他時間都好的:「Why does man print “gimme gimme gimme” at 00:30?」。

We've noticed that some of our automatic tests fail when they run at 00:30 but work fine the rest of the day. They fail with the message "gimme gimme gimme" in stderr, which wasn't expected. Why are we getting this output?

然後兇手跟作者都自己跑來出來說明 & 修正了 XDD

該 tweet 出自:

最近 man 怎麼這麼紅啊 XDDD (像是「10 Year Old Root Exploit Found in 'man' Command」),你們這些人不要亂搞啊 XDDD 這樣很吃大家通靈的時間啊 XDDD

AWS 推出新的 Cost Explorer API,不過 API 不是重點啦...

AWS 的「New – Interactive AWS Cost Explorer API」這篇文章在一開頭就提到了 Cost Explorer API 的情況,所以他們要推出新的 API 改進:

We launched the AWS Cost Explorer a couple of years ago in order to allow you to track, allocate, and manage your AWS costs. The response to that launch, and to additions that we have made since then, has been very positive. However our customers are, as Jeff Bezos has said, “beautifully, wonderfully, dissatisfied.”

不過讓我笑出來的是選圖啊... 大概是 Jeff Barr 夠硬的關係,直接選了這張:

我喜歡這張 XD (尤其配合著出現在官方 blog 上的時候)

在北美盜版 IPTV 產生的流量比 BitTorrent 還多

算是前陣子的新聞,在北美地區的盜版 IPTV 流量比 BitTorrent 的流量還多:「IPTV Piracy Generates More Internet Traffic Than Torrents」。

During peak hours, 6.5% of all downstream traffic on fixed networks is generated by TV piracy services.

To put this into perspective; this is more than all BitTorrent traffic during the peak hours, which was “only” 1.73% last year, and dropping.

如果把影音網站都考慮進去,最大的還是 YouTubeNetflix 這兩個啦,不過盜版的量也不小...

然後也有把最大的量分析出來,這裡面最大的量是 Indian Star Plus HD,應該是印度裔或是印度籍的人看家鄉的東西?

The most viewed of all in North America, with 4.6% of all pirated TV traffic, is the Indian Star Plus HD.

不過 Sandvine 一直都有方法分析整個北美流量,讓人感覺不太舒服...

大家在吵漢堡的 Unicode 呈現...

前幾天在 Twitter 看到這個 tweet,然後在高雄的時候 (MOPCON 2017),跟 zonble 聊天時他也提到這則 tweet 很有趣 XD:

然後有人回必要條件 XDDD:

結果微軟是對的 XDDD

然後這邊有實物照片:

不過比較有實際價值的是知道了「📙 Emojipedia — 😃 Home of Emoji Meanings 💁👌🎍😍」這個站台,可以查每個平台的呈現方式...

AlphaGo Zero 演算法的 Open Source 實做

Leela 的作者 Gian-Carlo Pascutto 依照 paper 的描述寫完了,放在 GitHub 上的 gcp/leela-zero

不過他在 Twitter 上也提到了,open source 實做不是真正的困難,真正的困難在於訓練完的資料,那個部份需要大量的成本才有辦法作到:

另外他推估 AlphaGo Zero 的計算量是 1700 年 (以 1080 Ti 來計算):「[Computer-go] Zero performance」。

另外 Leela 0.11.0 也推出了,還是先維持 policy + value 的方式,但引入了不少新演算法加強。另外一個蠻特別的地方是 Windows 版改用 clang 而變快不少:

Windows version is now compiled with Clang/LLVM 5.0 instead of MSVC2017. This makes the Monte Carlo evaluations about 15% faster.

雖然 DeepMind 說要收手,但還是留下不少方向讓大家走...
