Solved – The root cause why Netbeans can’t print colored text using latest Maven
Netbeans has bundled an old Maven, version 3.3.9, it can’t print out colored text to the output window. But when we switch to latest Maven 3.6.0, all color gone. I asked Netbeans guys, maven guys and jansi guys for help, but can’t get a solution. So i try to hack the maven code, i found…

Netbeans manually change color to green
Even the jansi library that built-in to maven 3.5.0 or above doesn’t work with netbeans, so we can’t output colored-text in Netbeans output window. But the “BUILD SUCCESS” word still in green. The reason is netbeans manually change the color to green. read count : 5

終於publish左第一個reactjs+typescript的UI component上npmjs
Publish當中最唔明就係點解要自己寫tsconfig同gulp人手張typescript同scss去transpile，呢一點同java好唔同，jar就係jar，唔會理你係邊到行，但nodejs個世界唔同，production同dev版本分別好大。你自己用npx create-react-app去創建新project，的確可以係local行，但就publish唔到上npmjs成功俾人用(可能係typescript同scss太煩)。而家個我個package可以同時俾reactjs同sharepoint spfx去用，可以build UI component library了。 read count : 26

打水程式
「打水程式」的電腦簽賭程式,利用兩個網站間對同一場比賽的不同賠率,自動找出同時押注兩隊均可獲利的比賽,從中賺取差價,獲利率幾乎百分之百。利用不同簽賭網站對同一場比賽訂定的賠率不同,從中賺取差價,早在國外及大陸地區風行多年,並有簽賭集團專門藉此牟利。早期均是靠人力坐在電腦前分析各個簽賭網站的賠率,稱之為「打水」,負責分析者稱為「打水員」,後來則演進為以電腦程式自動在簽賭網站之間找出可獲利的比賽,稱為「打水程式」。 舉例來說,一場A隊對上B隊的比賽,甲站對A隊開出賠率1:1,對B隊開出賠率1:0.9；乙站對A隊開出賠率1:0.8,對B隊賠率1:1.1。如同時下注甲站A隊10000元,乙站B隊9500元,比賽結束後,如A隊獲勝,甲站可贏10000元,乙站輸9500元,可獲利500元；若B隊獲勝,則甲站輸10000元,乙站可贏10450元,仍獲利450元。 弱盤打水：高勝率、高風險、高報酬 打弱盤才是近年打水的主流,目前台灣的球公司普遍都是這種打法,一般沒接觸打水的玩家很難將打弱盤和打水畫上等號,其實許多人在說的「假球理論」、「十賭九輸理論」、「明燈理論」,都是指向「弱盤理論」。打弱盤並不是打雙邊,而是只打單邊,就是永遠站在人少的那一邊；就單一場比賽來看打弱盤是打單邊,然而將整個投注模式放大後,打弱盤即是囊括了所有不公平盤底下得利的那一邊,「假球理論」指的是熱門投注球隊故意放水坑殺散戶,「十賭九輸理論」指的是注碼多的一方會輸球,「明燈理論」指的是賭桌上投注最多的那個賭客通常是其他賭客的明燈,跟他反向投注就會贏錢。 用比較科學點的角度來看,A隊在初始的平衡盤口讓B隊1分,但因為A隊是投注熱門,經過大量投注後變成讓B隊1.5分,此時買B隊等於比平衡盤多了0.5分的受讓,那勝率自然會拉高,所以打弱盤在理論基礎上並沒有什麼太大的缺陷,若能做到場場投注弱盤,也就是永遠站在55%以上勝率的那一方,那將時間軸拉長後確實是穩賺不賠的生意。 當然就短時間內來看,打弱盤的風險一定是所有水單中最大的,單邊投注就會佔到輸贏,而不是真的只賺水錢或分洞,但時間拉長後和別的水單並無二致,只是打弱盤會有更高的勝率,和折損更少的賠率損失,只要資金夠充裕可以承受一時的勝負擺盪,打弱盤無疑是報酬最好的打水方式。 什麼是足球打水？對於初次接觸的朋友可能會感到很陌生,足球打水本質上是利用了平台與平台之間的對賭,自己從中賺取利潤。比如意甲比賽我們在A平台上下注AC米蘭獲勝,在B平台上下注尤文圖斯獲勝,這樣不管最終是尤文圖斯贏,還是AC米蘭贏,我都能買中。因為賠率的關係,除去下注的金額,我們還能有盈利,這個過程我們就稱為足球打水。足球打水為什麼能夠獲利呢？這裡面有一個很關鍵的因素——賠率,上一段中也有提到。賠率是菠菜平台經過嚴密計算綜合得出的,這就跟保險公司確定保險範圍和收費一個道理。一般情況下,一場比賽,根據兩隊交戰歷史紀錄,兩隊最近狀態,主客場勝率等,會確立3個賠率。我們先來簡單了解下賠率,後面我們在說打水套利的公式是怎樣的。 賠率計算公式：a÷b=c cc×10%=d 這裡面d就是最終計算出來的賠率 a是基數,值為100 b是莊家分析師分析出來的百分比概率 c是a / b的結果 舉個例子: 世界杯中巴西與阿根廷的比賽,莊家通過分析得出巴西勝出的概率為40%左右。那麼就用這個公式來計算如下： 第一步100÷40=2.5 第二步2.5-2.5×10％=2.25 那麼,莊家開出巴西的賠率會在2.25左右。 如莊家通過分析得出打平的概率為31％左右,那麼就用這個公式來計算如下： 第一步100÷31=3.22 第二步3.22-3.22×10%=3 那麼,莊家就會開出平局的賠率會在2.89左右。阿根廷獲勝的賠率也可以按照相同的方法計算出。 上面就是賠率的簡單計算過程中,不過賠率並不是固定不變的,Bet公司會根據球隊的狀態已經下注的情況,動態調整比賽賠率,因為賠率有了動態的變動,我們才有足球打水的機會。那麼足球打水套路公式是怎樣的呢？ 計算方法：上盤,假設回水1%,下注2000,水位1.00,輸贏都是2000。下盤,假設回水1%,下注2020,水位0.98,如果下盤贏就賺2020*0.98,2020*0.98 + (2000+2020)*1% – 2000=19.8,賺19.8塊；如果下盤輸,2000+ (2000+2010)*1% -2020=19.8,一樣賺19.8塊。 足球打水之所以能夠盈利,就是因為不同Bet平台有賠率變動的時間差,抓住這些時間差,我們足球打水就能夠獲利。 read count : 131
