Somehow I couldn't find the answer in Google. Probably I'm using the wrong terminology when I'm searching. I'm trying to perform a simple task, convert a number that represents a character to the characters itself like in this table: http://unicode-table.com/en/#0460 For example, if my number is 47 (which is '\'), I can just put 47 in a char and print it using cout and I will see in the console a backslash (there is no problem for numbers lower than 256). But if my number is 1120, the character should be 'Ѡ' (omega in Latin). I assume it is represented by several characters (which cout would

【并发那些事】可见性问题的万恶之源 <br> > 硬件工程师为均衡 CPU 与 缓存之间的速度差异，特意加的 CPU 缓存，竟然在多核的场景下阴差阳错的成为了并发可见性问题的万恶之源！( 本文过长，如果不是特别无聊，看到这里就可以了 ) 前言 还记得那些年，你写的那些多线程 BUG 吗？明明只想得到个 1 + 1 = 2 的预期，结果他有时候得到 1，有时候得到 3，但偏偏有时候他也会返回正确的 2。明明在本地运行的好好的，一上线一堆诡异的 BUG。你一遍一遍的检查代码，一行一行 debug，结果无功而返。<br> <br>变量为何突然变异？代码为何乱序运行？条件为何形同虚设？欢迎收看今天的《走进科学》之半夜。。。哦，不对，欢迎阅读今天的《并发那些事》之可见性问题的万恶之源。就像上面说的，我们在写并发程序时，经常会出现超出我们认识与直觉的问题，而按我们的以往的经验，很难去察觉到他的问题所在。而又因为我们不了解他发生的诱因，即使我们按照书上的方案解决了，但是下次还是会出现。所以本文的主旨并不是解决问题的术，而是解决问题的道。一起来探究多线程问题的根源。<br> <br>首先揭开谜底，大多数并发问题的发生都是这三个问题导致的， 可见性问题、原子性问题、有序性问题 。那么又是什么导致这三个问题的出现呢？本文将一步步解析可见性问题出现的原因。<br> 核心矛盾 众所周知

For internationalized data it would be great to work with the \ResourceBundle class from PHP's "intl" extension. I got the extension running (PHP 5.3.4; Windows) and created a .dat file using the ICU Data Library Customizer *, but I don't get the expected result from the resource bundle class. Now I do this $bundle = '/var/www/libs/icudt48l.dat'; $resource = new \ResourceBundle('en_US', $bundle, true); var_dump($resource, is_file($bundle)); //--> NULL, TRUE The problem is $resource returns NULL without any errors being raised. What's going on? *(Only the last two data sections were checked

Apple says that NSRegularExpression is based on the ICU Regular Expression library: https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSRegularExpression_Class/ The pattern syntax currently supported is that specified by ICU. The ICU regular expressions are described at http://userguide.icu-project.org/strings/regexp . That page (on icu-project.org) claims that Named Capture Groups are now supported, using the same syntax as .NET Regular Expressions: (?<name>...) Named capture group. The <angle brackets> are literal - they appear in the pattern. I have written a
