java - Could the Drools update method potentially be causing my problems -

-

I am currently writing an application using Drools 5.0. This application is running a bit slow, but I have a theory why this app already receives many updates for the facts stored in the Knowledge Session. Under the hood the drals update function is actually a comeback, then there is an entry. There are more than 200 rules in this application: Some rules are written when some facts are removed. Other rules are written in the fire when some facts are called in the knowledge session. Since the update is actually a comeback, then will there be an exhaustion and insertion related rules still under fire during an update? Regardless, nothing can be really 'put' or withdrawn from the knowledge session?

One thing to note, I have bowed down the working memory logger for my knowledge session to get a better idea about what is happening. When I saw many unexpected return / entry rules-activation composition being added to the agenda, but it seems that they are never active. It seems that updating the facts can be expensive depending on your particular model, and I should use a little bit is it right?

I think you have understood it correctly. An update is a kind of withdrawal and an emphasis. The first thing to do is to ensure that if your rules are giving you - that is how it works, but do you want to improve performance only?

In some ways you can think of updates (and can also checkout the "modified" keyword). As part of the evils of disqualification;) When you update - you tell the network that the fact has changed, but it still keeps track of any field level (which is TBD), so it does more work May be necessary, because all these activations have been created which are not really necessary (because they are using areas that have not actually changed in value).

It's hard to be more specific - if you've provided some sample rules / facts models (if you can definitely do it safely!) We have more granular to break it.

Good luck!

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
