In the early days, Digg was actually a wiki. All the content was created by users. This is the essence of Digg and the biggest difference between Digg and the old news websites. In my opinion, the voting mechanism is more in order to provide a better user experience, so that users can feel that they are "taking the lead" (in fact, they do not use voting, it is also possible to rank news by clicking rate ).The current Digg has added a re
The Wiki engine of codeplex is now open-source. In addition to basic la S such as lists and tables, wikiplex also provides embedded videos (such as flash, QuickTime, and YouTube), Silverlight components, and RSS sources, and provide corresponding macros. For RSS feeds, up to 20 items can be displayed in title mode or full content mode.
Because this is orientedProgramSo wikiplex can also color some popular

The template engine based on regular expression substitution can easily meet the limit of the maximum backtracking/recursion of regular expressions.
Lazy matching is not scary, normally the template is not enough, often does not exceed the limit, the Discuz template engine is heavily used. But instead of paying attention and not learning, it is easy to write mist
I 've been writing this for the last 20 days... it's finally finished (the road to endless reconstruction ...)... I would like to thank the author of VC and re2 for their blog guidance and the source code reference of VC. thank you very much! Great inspiration. The scheme of traversing part of the regular syntax tree of VC aggregation is really subtle! Previously, although I knew how to traverse heterogeneous trees in the visitor mode, I did not know how to write the vistor framework to meet the

Python has its own regular expression engine (built-in re module), but the supported features are thin, and none of the following features are supported:
Curing Group Atomic Grouping
Occupy priority quantifier possessive quantifiers
Variable length reverse-order surround Variable-length Lookbehind
Recursive matching Recursive patterns

Regular expressions are basically used by every programmer, but implementing the regular expression engine seems like a difficult task. In fact, a simple regular expression engine can be realized by mastering the lexical analysis of the front-end of the compiling principle. This is a recommended course for NetEase Clou
Usually writeCodeCertainly, mistakes are inevitable. How can we reduce the chance of making mistakes? We can only exercise more and pay more attention to it. The difficulty of software development is the complexity of the processing nature, that is, the complexity of the business logic itself, rather than solving some technical difficulties. As developers, on the one hand, we need to read more books, increase the knowledge width, learn new technologies, and maintain technical sensitivity. On the

With the previous chapters, we are certainly confused. How can activiti be integrated with actual business, such as a purchase order, and how can it be associated with a process instance?
Here we need to use activiti to set the businessKey of a process instance when starting the process instance (usually store the id of one of our purchase orders)

Rule 1: The Regular Expression Engine Starts matching the input string as soon as possible. It searches for one character at a time until it finds a match.
For example:
String = 123 ABC 456 def
RegEx = [A-Z] *
Matching starts from ABC.
Rule 2: After a matching start is found, the Regular Expression Engine con

A jumble of notes, may be the noise, the same note through the composer's hand, you can draw a very beautiful music, a performer can also play the music of the melody, but he/she may not know how to change the combination of notes, make the music more beautiful.
As regular users also, do not understand the principle of the engine, the same can be written to me

I haven't encountered a PHP problem for a long time. This Regex problem takes a little time, and it is still the biggest backtracking and recursive restriction problem of the old problem. It is not difficult to modify the regular expressions with such problems after the learning is done. The main points are as follows. The template engine based on regular expression replacement is prone to the limit of maxi
