這門課為誰設計?
幾乎所有人! 資深的 JavaScript開發者將可比別人快一點完成這門課,這門課的設計以讓學員覺得可親近且有趣為主。
有些影片所談的主題對有些人可能會覺得有點傷腦筋,如 scoping、 keyword this 與 prototypal inheritance.
這不是從基礎開始的 JavaScript課程,所以如果你在找初學者的課,這可能不是你的選擇。 你需要有一些函數(functions)、變數(variables)、物件(Objects)、陣列(Arrays)和其他基礎知識。
1. 依賴jQuery者:想要更好地了解JavaScript核心功能
2. 既有JS開發者:想要跨過個人的學習缺口並將ES6從頭到尾走過
3. PHP和WordPress開發者:想要在client端變得更強
4. 任何想要精進 JavaScript且想好好從基礎到進階觀念實用性地參透

📜 [專欄新文章] 0xDonate — An Ethereum donate service for streamers

給實況主的區塊鏈斗內服務
透過 Ethereum Smart Contract,讓觀眾可以一鍵斗內給實況主,並讓斗內訊息在實況中即時推播出來的小服務
0x Donate
前言
現在的實況主大多是透過PayPal、歐付寶等第三方支付來接受觀眾斗內。但如果實況主不想被抽手續費,或想讓觀眾直接斗內加密貨幣給他呢?直接留下錢包地址是一個方法,但誰斗了多少很難即時查看也缺乏跟觀眾的互動。
因為最近剛好有點閒時間,所以就寫了個網站,透過智能合約讓實況主也能跟斗內的乾爹們互動。
How it works
網站的架構相當簡單,只要有一個錢包地址就可以開始使用了。實況主輸入錢包地址就產生對應的3個連結
1. Donate Page
就如同傳統的第三方支付,實況主將斗內連結放在個人的介紹頁面中,觀眾直接透過那個連結捐款。填完想說的話和金額,按下按鈕使用 Metamask 送出交易就完成了。
以Twitch為範例
2. Notification Page
這個頁面會監聽合約上的event,當有人斗內時就會跳出斗內訊息、斗內人名稱和金額。實況主只須於OBS Browser source把這個連結設定好即可。
3. History Page
誰是最大乾爹? link
不免俗的每個實況主都有他的Top donation list,這個頁面會把鏈上的斗內紀錄抓下來彙整成一個排行榜,讓實況主輕鬆看出誰是最大乾爹,乾爹們也不用擔心自己的心意不會被看到,都已經寫在鏈上了。
Features
0 fee, 0 setup, only a 0x address required
0 fee
對比現在第三方支付,本服務不抽手續費。以歐付寶為例,如果有人信用卡斗內十元,就有高達五元會被抽走。而0xDonate只需送出交易的人負擔交易本身gas費用,實況主可以獲得全額捐款。
0 setup
不需要註冊,不需要綁定任何API Key。不論是Twitch、Youtube Gaming 或是其他平台都能夠使用。
0x address
有一個錢包地址就可以開始使用了!
The Contract
其實合約本身也蠻簡單的(?),目前是部屬在Ropsten Testnet上。
donate 負責將ETH轉到實況主的地址,並觸發NewDonation ,讓斗內資訊可以在實況中顯示出來。而為了省gas,合約並沒有將斗內訊息的內容寫到鏈上。
getDonation 查看鏈上的紀錄,以用來產生乾爹排行榜。
一些開發上的雜談
在半年前於Reddit上看到類似的服務 NanoTwit.ch,就有想說來玩玩看一個ETH版本的。最早的prototype是之前寫的 SimpleEth,一個一鍵打交易的jQuery插件。雖然拖了很久我猜市面上已經有類似的服務了,不過秉持著『頂著幹,做中學』的精神,還是把這個專案寫完了。
都2018年了寫網頁怎麼能不用框架呢?
平常寫前端沒什麼在用框架,這次嘗試看看用快過氣的React 把半成品 ETH-Stream-Donations 包得更現代化些。過程中要特別感謝 @wingemerald 提供技術上的支援。但不得不說React跟一些雜七雜八的dependency真是肥大,有時候webpack跑一跑小筆電的風扇就轉起來了。
開發上有遇到一些小阻礙,一個是web3的雷,為了要支援火狐所以就換了版本。另一個是新版本web3為了要監聽合約的Event必須要使用 Websocket Provider,就改成使用infura的ws節點。
其他都還算順利,畢竟合約部屬好前端包一包就差不多完工了,資料都在鏈上不用處理後台也是挺方便的。
結語
很多人說區塊鏈是不是過譽了,但我相信Ethereum健康的開發者社群,總是會有些新的點子生出一些有趣的DApp或應用出來。
雖然是個寫好玩的 side project,但歡迎不論是有在實況或是有興趣的朋友都去玩玩看,在測試鏈上人人都可以當乾爹!

麻煩大家幫忙
留下優秀的一家人
他們來自波多黎各
父母親都是名校約翰霍普金大學的電腦碩士
(Master Degree in Computer Science - Johns Hopkins University at Laurel, MD)
他們著五個孩子,到全世界學習
Diego 17歲 Paula 13 歲 Alonzo 12 歲
Felizi 8 歲 Matteo 6 歲
八月,他們到了台灣
發覺這是一個非常適合的生活環境
有好的醫療、中文學習環境、電腦產業、和超好吃的水果
九月,Diego , Paula, Alonzo進入惠文高中寄讀
他們來了之後,學校形成一個很棒的英語學習情境
台灣學生都被迫用英文跟他們互動
星期五與台北歌德學院簽訂德國「PASCH夥伴學校」時
他們三個和學校弦樂社一起合奏卡農(見影片)
非常非常有教養的一家人
然而他們11月就必須離開台灣
因為他們來台灣的第五天
得到美國總公司的通知
他們收掉波多黎各的公司
爸爸Tommy失業了
所以這幾天,他在台中接一個英文家教
但經濟仍是問題
如果台中的朋友可以提供11月4日前的短期英文、西班牙文家教工作
或是提供長期電腦工程師的工作
麻煩和Tommy聯絡
以下是他的聯絡方式及完整資歷
(願意幫他們申請工作簽證更好)
他們很願意把台灣當成第二個家
PS
覺得政府說要把英文變成第二語言
最棒的方式是吸引國外的學生進入我們的校園
在人才即國力的年代
讓優秀的國際人才留在台灣
如果在台灣就有很好的英語學習環境
我們就不用一窩蜂跑到國外

Web Developer / Web Master for the Department of Veterans Affairs in DC
Mr. Irizarry developed a web based application for the State Home Per Diem Office, which manages millions of dollars in payments to the state homes, to replace an Access database. The Access database was converted to MS SQL Server database and all data was migrated successfully. He created a web based interface using the standard VA intranet look and feel. He also developed a custom interface for each of the 3 roles (CBO, VAMC and VISN). Tools were built for the administrator to view current reports, view missing reports lists, and configure many parameters in the application. The VAMC report form was heavily automated using jQuery to perform auto calculations, increasing data validation and saving time to the users. After the application was launched users commented frequently about how user friendly is the new interface and about the time savings. Tasks that will take 2 hours to be completed now take 15 minutes. We have close to 12,000 reports in the system.
There were various requests to the IT office for a web based training registration system of different types.

Developed an alternate cascading style sheet for SharePoint 2007, converting the out of the box look and feel to the Department of Veterans Affairs standard website look and feel.
After one of the VA’s laptops was stolen Mr. Irizarry worked to develop a Risk Assessment web based application. He created an Excel template which management will upload to an FTP server with information and details about remote employee access and the sensibility of the data accessed by those users. He also created VB Scripts to validate those Excel files an upload that information into an MS SQL database. Reports for upper management in Central Office were then created which prompted management to enforce stronger security measures, like hard drives encryption. In total more than 500,000 records were processed for the reports.
