What is the difference between dynamic languages and functional languages? -

-

I often find that developers use together working language and dynamic language words, and think that Why are they always kept together, what is the difference between them? What language can be dynamic and functional? Are they complementary to each other? Why do we want them anyway? I am a C # programmer and so far it is not understood as a full dynamic / functional thing (there are some dynamic features in C # to 4). Will it also be functional? What's going on here?).

To put it in a simple (but not correct) answer

  • They are: Type (class name) is not important Languages ​​typed with the stability of its namespace can be different types of objects given at any given time at any given time. Method invocations are resolved at run-time, that means you lose the benefits of stable typing (compiler warnings), but generic by normal means - sort (list) string. Such as Ruby at all
  • Price irreversibility programs are written in the context of big and big tasks (usually down) The concept of object position and variability is in this context < Strong> self-sufficient (terminology is pure according to Wikipedia): Everything that requires production, gets in the input it receives. This is no side effects (unless it is explicitly mentioned) and returns consistent output for a given input. This can be an elegant code (see: Fluent Interface), where input data is pipe through the FIFF functions to produce interval output. LISP et.all

However, it is disturbing with the boundaries of choosing the best languages ​​in all languages ​​... You can make a language that is both, both one or two . E.g. Taking the Lambda Expressions mainly in static C # 3.0 and driving capabilities with 4.0 is brought.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it.

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
