design - Efficiently record and store page view counts in the database? -

-

Show sites like Stacks overflow count, save, and display visual counts for pages. How do you do it efficiently? For example, we take the number of views for stack overflow queries. I look at the following options.

Option 1 When the application receives a request for a question, the count in the question table increases. It is very disabled! The majority of questions are read-only, but you are attacking every single update.

Option 2 Keep any type of cache that calculates the new view of the map questionIds. When the app receives a request for a question, increasing the view number cached for the question id you are caching marginal increase in ideas. So far, so good. Now you need to count in the cash from time to time. This is the second part of the problem. You can use another thread or some sort of scheduling component. This is actually a different question and partly depends on your server platform (I am using Java). Or, instead of using a different thread, after the number stored in a certain number in the cache, you can make an update within the request thread that reached the threshold Some IQ points in the cache can be updated in the cache.

I like the idea of ​​a cash when a threshold is reached. I want to know what others have done and if there is a better way.

I agree that writing every page in the database is disabled. My approach is to cache the requests, then do them once in one hour. Every time I update the cache, I compare the current time for the last lighttime, and if more than an hour has passed then I write. This is an ASP.NET application, so I have a final commitment in the application's shutdown method. The latter is not guaranteed to run, though acceptable loss is considered.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
