EDA adjustments caused instabilities in mining difficulty of the Bitcoin Cash system, resulting in Bitcoin Cash being thousands of blocks ahead of Bitcoin. To address the problem with stability, a change of the Bitcoin Cash DAA was implemented and the EDA cancelled. The change took effect on 13 November 2017. After the change, the Bitcoin Cash DAA adjusts the mining difficulty after each block. To calculate the difficulty for a new block, the Bitcoin Cash DAA uses a moving window of last 144 blocks.[36]


主人公贾马尔就是作者心目中的神,他对美好事物的不懈追求被影片渲染得感人至深。他在任何情况下都从不放弃对心中圣洁化身的拉提卡的追求,无论是金钱的诱惑,还是生命受到威胁,都没有窒灭他的所求。在看到自己心爱的人被哥哥抛弃时,一向尊重哥哥的他怒不可遏。他参加百万富翁的节目,不是为了成为百万富翁,而是为了寻找拉提卡。他的性格是那样单纯,他的心灵是那样干净,这简直就是作者富有诗意的创造,寄托着作者对美好人性的无限渴望和对世俗对人性美的冲击的深深忧虑。银幕上这样一个简单、率直又可爱的个性赢得了许多观众的“垂青”,他时常说的一句“It's our destiny.”(这是我们的命中注定),更引来了无数粉丝的尖叫。的确,在现实生活中,一个拥有这样美好心灵的人都是很值得我们尊敬的,但在他没有成功以前,这样的人很容易被人看作为是“一根筋”。

  MD5还广泛用于操作系统的登陆认证上,如Unix、各类BSD系统登录密码、数字签名等诸多方。如在UNIX系统中用户的密码是以MD5(或其它类似的算法)经Hash运算后存储在文件系统中。当用户登录的时候,系统把用户输入的密码进行MD5 Hash运算,然后再去和保存在文件系统中的MD5值进行比较,进而确定输入的密码是否正确。通过这样的步骤,系统在并不知道用户密码的明码的情况下就可以确定用户登录系统的合法性。这可以避免用户的密码被具有系统管理员权限的用户知道。MD5将任意长度的“字节串”映射为一个128bit的大整数,并且是通过该128bit反推原始字符串是困难的,换句话说就是,即使你看到源程序和算法描述,也无法将一个MD5的值变换回原始的字符串,从数学原理上说,是因为原始的字符串有无穷多个,这有点象不存在反函数的数学函数。所以,要遇到了md5密码的问题,比较好的办法是:你可以用这个系统中的md5()函数重新设一个密码,如admin,把生成的一串密码的Hash值覆盖原来的Hash值就行了。


“The arguments have devolved over three or four years of bitter debate, the principles are real and they are important to preserve, but a lot of the drama has nothing to do with principles anymore. A lot of this debate is now more about hurt feelings. It’s about bruised egos. It’s about things that were said that can’t be unsaid, insults that were exchanged, and personalities and ego.”

  而 Jamal 是个不折不扣的理想主义者。他善良而执着,对 Latika 一直不肯放弃。 Salim 在火车上数钱的时候, Jamal 脑子里想的都是 Latika ,兄弟俩的人生观一目了然。演员 Dev Patel 现实中也是只有 18 岁,有人说 Jamal 看起来太单薄,跳起舞来都是长手长脚的。但是这有什么关系呢?外型虽然薄弱,意志却无比坚强。 开头被拷打时,胖警察报告审了他一夜,除了名字什么都没问出来——“ He’s a tough guy.” 他的长官说“ What the hell can a slumdog possibly know” 的时候,背后被电晕的 Jamal 吐了一口血:“ The answers.” 这个镜头,我印象非常深刻。 18 岁的 Jamal Malik 因为这种坚强而显得格外性感。如果说这部电影是个童话,那也一定是因为 Jamal 这种近似不可能的执着和坚持,而不是男女主人公的离奇爱情故事。选不出“ Truth Alone Triumphs.” 的 Jamal ,他的人生故事却是这句话的完美诠释。 如果 Salim 是那个社会的代表型人物, Jamal 就是印度人民的精神象征,这就解释了为什么 Jamal 的天真善良和理想主义是理所当然的,也解释了为什么 Jamal 赢大奖后人们都为他兴奋欢呼。


As a merchant one of your main goals is to be able to accept and process payments as quickly and seamlessly as possible so you can make your customers happy and receive payments without any headaches. Bitcoin Cash is the solution, as it has fast and low-cost transactions. As the world goes digital, electronic currencies such as Bitcoin are becoming the go-to method for paying online and in retail shops. Easily accept Bitcoin Cash directly or use third-party providers to accept Bitcoin Cash using their platforms and convert all or part of the sale into local fiat currency.


Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.


To keep the block generation time equal to ten minutes on average, both Bitcoin and Bitcoin Cash use an algorithm adjusting the mining difficulty parameter. This algorithm is called the difficulty adjustment algorithm (DAA). Originally, both Bitcoin and Bitcoin Cash used the same difficulty adjustment algorithm, adjusting the mining difficulty parameter every 2016 blocks. Since 1 August 2017, Bitcoin Cash also used an addition to the DAA, called an Emergency Difficulty Adjustment (EDA) algorithm. EDA was used alongside the original DAA and it was designed to decrease the mining difficulty of Bitcoin Cash by 20%, if the time difference between 6 successive blocks was greater than 12 hours.[36]
