Matomo NAMED 2023 Hi-Tech Awards finalist
1er août 2023, par Lance — Press ReleasesWELLINGTON, N.Z., April 20, 2023 – InnoCraft, the makers of world-leading open-source web analytics platform Matomo, has been named an ASX Hi-Tech Emerging Company of the Year finalist in the 2023 Hi-Tech Awards.
Matomo founder Matthieu Aubry says, “At Matomo, we believe in empowering individuals and organizations to make informed decisions about their digital presence. By providing an open-source website analytics platform, we have created a more transparent and trustworthy digital ecosystem. We are proud to be recognised as a finalist for the Hi-Tech Awards, and we will continue to work towards a more open and ethical digital landscape, and grow the business in New Zealand and worldwide.”
About Matomo
Matomo, launched in 2007 as an open-source, privacy-friendly Google Analytics alternative, is trusted by over 1.5 million websites in 220 countries and has been translated in over 50 languages. Matomo tracks and analyses online visits and traffic to give users a deeper understanding of their website visitors to drive conversions and revenue ; while keeping businesses compliant with privacy laws worldwide, such as the EU’s General Data Protection Regulation (GDPR) and The California Consumer Privacy Act (CCPA).
Aubry says Matomo is performing extremely well internationally as consumers and organizations look for privacy-focused analytics solutions, with several European countries already ruling the use of Google Analytics illegal due to data transfers to the US. In addition, Matomo’s user increase was recognized earlier this year with W3Tech’s award for the best web analytics software in its Web Technologies of the Year 2022 – with previous winners including Google Analytics and Facebook Pixel.
A record number of companies entered the 2023 Hi-Tech Awards, with entries coming in from across the country and from all areas of the Hi-Tech sector. This depth is reflected in the line-up of finalists this year, according to David Downs, Chair of the Hi-Tech Trust, who says the standard of entries continue to grow every year. ”
The hi-tech sector continues to flourish and it’s fantastic to see the success that so many of our companies enjoy on the international stage. This sector continues to prove its resilience and is at the forefront of our export economy in turbulent times,” says Downs.
The Hi-Tech Awards Gala Dinner will take place on Friday, the 23rd of June, in Christchurch.

Frames from Video Using OpenCV in Ubuntu with Java 17
2 août 2023, par bstrdnI've been trying to extract frames from a video using OpenCV in an Ubuntu environment with Java 17, but all my attempts have been unsuccessful so far. The main issue is that ffmpeg is not detected by the OpenCV library on ubuntu.


Here's my test code :


Main class


import org.opencv.core.Core;
import org.opencv.videoio.VideoCapture;

public class Main {
 public static String videoPath = "";
 static {
 String osName = System.getProperty("os.name").toLowerCase();
 if (osName.contains("win")) {
 System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 videoPath = ClassLoader.getSystemResource("video.mp4").getPath();
 } else {
 videoPath = "/video.mp4";
// System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
 System.load("/usr/lib/opencv_java470.so");
 }
 }

 public static void main(String[] args) throws InterruptedException {
 VideoCapture videoCapture = new VideoCapture(videoPath);
 if (!videoCapture.isOpened()) {
 System.out.println("Error opening video file.");
 } else {
 System.out.println("Everything is fine.");
 }
 System.out.println(Core.getBuildInformation());
 Thread.sleep(1000000000000000000L);
 }
}
