I am trying to track performance on some procedures that run too slow (and seem to keep getting slower). I am using v$session_longops to track how much work has been done, and I have a query (sofar/((v$session_longops.LAST_UPDATE_TIME-v$session_longops.start_time)*24*60*60)) that tells me the rate at which work is being done.
What I'd like to be…
Hi,
In an application harvesting (many) RSS feeds, I want to dynamically schedule the feed downloaders based on the following criteria:
The speed at which content are generated - source which produce content at a higher rate need to be visited more often. After downloading a feed, its content is analyzed and based on the current rate of…
Hello all this is my first post. I'm working on a homework assignment with the following parameters.
Piecework Workers are paid by the piece. Often worker who produce a greater quantity of output are paid at a higher rate.

I have an array set with the heights of each hidden div, but when I use it, the div instantly jumps down, rather than slowly sliding as when there is a literal number.
EDIT: testing seems to reveal that it's a problem with the push method, as content_height.push(item.getElement('.moreInfo').offsetHeight);alert(content_height[i]);gives…
So, I'm building a WPF app and did a test deployment today, and found that it performed pretty poorly. I was surprised, as we are really not doing much in the way of visual effects or animations.
I deployed on two machines: the fastest and the slowest that will need to run the application (the slowest PC has an Intel Celeron 1.80GHz…
Hello.
I'm trying to create a good way to handle all possible collisions between two objects. Typically one will be moving and hitting the other, and should then "bounce" away.
What I've done so far (I'm creating a typical game where you have a board and bounce a ball at bricks) is to check if the rectangles intersect and if they…
I am trying to use PHP to send text to an LED sign so I can send support ticket numbers to it. The sign itself is a piece of work; it came from eBay and is poorly made with almost no documentation. After fiddling with it for a while, I was able to figure out the way it expected stuff to be sent to it and that the baud rate is…

After getting some performance issues for an application using a MySQL database, I'm thinking of using NoSQL solutions.
My architecture is as follows:
One application receives messages from the network at a high throughput (i.e. 50000 messages/sec). Each message is stored in the DB, so…
For some reason, when a WAV file is played back using the snippet below, it randomly plays back screwy, like a high pitch noise. It doesn't happen all the time, just randomly. It seems to happen more often when it is played back more frequently. The WAV properties are below along with…
