I am having trouble deciding on whether to classify my application as 'real time' or 'near real time', or perhaps even something else. The software receives data immediately as it is generated from the source, then based on certain rules, raises an alert when certain conditions are met. It takes the approach of checking the last 30 seco...
Hi, I may be doing an iPhone-based application doing near-real-time sound-processing (filtering, etc). I was wondering the best way to get started. Would I want to create an audio cue for recording and processing sound, as described here? Edit: I should be clear. I am not asking how to do signal processing, in general. I know some of...
A while ago I came across an interesting array of video presentations on a German company's website. They deal with modifying a video stream while it's playing, and I remained pleasantly impressed by the accuracy and smoothness of this technique. Out of all these presentations, I considered one of them quite fascinating in terms of text ...
Consider following assumptions: I have Java 5.0 Web Application for which I'm considering to use Lucene 3.0 for full-text searching There will be more than 1000K Lucene documents, each with 100 words (average) New documents must be searchable just after they are created (real time search) Lucene documents have frequently updating inte...
Hey all, I would like to make a Google map overlay with changable pins. An easy way to visualize this would be to think of a near real time overlay, where the pins are constantly changing location. However, I can't seem to think of a safe way to do this with the ItemizedOverlay. The problem seems to be the call to populate - If size(...
Background: I have a PostgreSQL (v8.3) database that is heavily optimized for OLTP. I need to extract data from it on a semi real-time basis (some-one is bound to ask what semi real-time means and the answer is as frequently as I reasonably can but I will be pragmatic, as a benchmark lets say we are hoping for every 15min) and feed it...
<?php // Execute a shell script $dump = shell_exec('bigfile.sh'); // This script takes some 10s to complete execution print_r($dump); // Dump log to screen ?> When the script above is executed from the browser, it loads for 10s and the dumps the output of the script to the screen. This is, of course, normal. But if I want the dat...
I have a need to convert audio samples from 11025 and 22050 to 44100; I'm looking for the fastest and best sounding conversion routine. I require that the answer be given in pure Java, without the need for external routines or libraries. The source is an array of short values representing left and right channels, interleaved like so LRLR...
