libraries. higher level makefiles specify the services they want. when the libraries for a service change only the lower level makefiles will have to change. keep a Repository Most companies have no idea what code they have. and most programmers still dont communicate what they have done or ask for what currently exists. the solution is to keep a repository of whats available. in an ideal world a programmer cocould go to a web page, browse or search

multiple search-replace operations within the global scope of the target object, you can use the parameter "g", that is, s/love/lust/g. In addition, if we do not need to restrict the matching case format, we can use the parameter "I ". For example, M/JewEL/I The above regular expression will match jewel, Jewel, or JEWEL in the target object. In Perl, the special operator "= ~" is used ~" Specifies the matching object of the regular expression. For example: $ Flag = ~ S/abc/ABC/ The above regula

, the load failure is displayed. The statistical data above shows that the same behavior in Chrome, FF, and IE is loaded with invalid Datauri Scheme. The delay is also relatively short and stable. So jsdeffered uses this approach to speed up asynchronous execution!Iv. SummaryThis is only the IMG element loading HTTP, JavaScript and data URI scheme, and so on, coupled with experimental methods and other issues, inevitably lead to statistical data is not comprehensive, if there is a mistak

Lonely brother has recently been busy writing something about interaction and user experience.Article, Has been busy, even to stay up late to fight. As a result, the blog has not been updated over the past few days. I am sorry to you. From today on, I will resume content updates. First, we will share a PPT entitled "Internet Development Trends abroad". This PPT was shared to me by a friend via Google Docs yesterday.

difficult for traditional iterations and Array Operations. Don't be discouraged. Writing compatible and refreshing code and APIS is the most important thing.Conclusion Just like all the syntax features added later (Do you remember the Java Generics feature? And the php oop features of the past few years), they all need time to work together and ultimately stabilize. As PHP5.3 and PHP6 become more popular in the future, more and more skills and features are believed to be gradually mined by smar

"; The above can also be written in this way. At this time, we find that the comma in Perl is used here: Print "the answer is", 6*7, ". \ n "; 13. variables can be directly written into double quotes, so Perl will replace the variable value. Note that unspecified variables will be printed as empty strings, in addition, if Perl's warning is enabled, Perl will complain that we are referencing undefined variables. If we want to print a $ symbol, it is OK to use the backslash escape directly. Like

This cocould be very handy in case of debugging when you need to know whats the exact error message. Also for this code to work properly you need to configure your ls app to useSecurityadministrationPermission while debugging.This can be set via proper

who are still wondering whats going? Basically use the same idea, but instead of looping over the entire number, sum up the number in blocks of 3 (octal) and count them in parallel. After this statement ucount = N-(n >>1) 033333333333)-(n >> 2) 011111111111 );Ucount has the sum of BITs in each octal block spread out through itself. So if you can a block of 3 bits U = a2 * 22 + A1 * 2 + a0;U> 1 = a2 * 2 + A1;U> 2 = a2; U-(u> 1)-(u> 2) is a2 + A1 + a
