java - Would one have to know the machine architecture to write code? -

-

Assume I'm doing Java or Python or C ++ programming for a simple problem, a TCP / UDP echo Can the creation of the server or the fabric of the calculation have to disturb me about the architecture details, that is, if it is 32 or 64-bit?

IMHO, Unless I am doing some programming with very low-level content, then I do not want to bother if 32 or 64 bit is going to mistake me? Or am i right

Correct for most situations

Runtime / The language / compiler will be an abstract of those details, unless you are working directly with the word size or binary at a lower level.

Even the byteorder is explained by the NIC / Network Stack in the kernel. This is translated for you. When programming sockets in C, you sometimes have to deal with the byte sequence for the network while sending data ... but it is not related to 32 or 64 bit differences.

When dealing with the blobs of binary data, they can create problems from one architecture to another (for example, form an overlay in the form of C) as others have mentioned , But this is the reason why we develop architecture independent protocols on the basis of characters and so on.

In the virtual machine, like real objects like Java, tabulate the machine Know a little and how this syntax is compiled that you can help to understand the platform and write cleaner, hard code. I know that after studying the compilers, I am disturbing some old code!

c++ - Linux and clipboard -

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. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

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
