• How to correctly setup Linker in Eclipse IDE 4.8.0M4 for ffmpeg development (Ubuntu)

  28 janvier 2018, par boergi

  I am using Eclipse IDE 4.8.0M4 on Ubunto 16.04. I try to compile the code from a FFmpeg tutorial on GitHUB : (https://github.com/leandromoreira/ffmpeg-libav-tutorial/blob/master/0_hello_world.c). For setting up FFmpeg in Eclipse i used this guide :(https://trac.ffmpeg.org/wiki/Setup_Eclipse_IDE_for_FFmpeg_(Linux)).

  The header files and libaries are all in the folder /home/git/ffmpeg. (e.g. avcodec.h and libavcodec.a is in the folder /home/git/ffmpeg/libavcodec). Included libs : -lavcodec -lpostproc -lz -llzma -lrt -lavfilter -lswresample -lavdevice -lswscale -lavutil -lavformat

  Console output :

  I found out that "int avcodec_parameters_to_context(AVCodecContext *codec, const AVCodecParameters *par)" is defined in utils.c (also in the /libavcodec folder), but i don’t know what can i do to get this running.

• 5 questions you should ask yourself before defining a custom alert in Matomo

  24 janvier 2018, par InnoCraft

  In Matomo, you can create Custom Alerts to automatically be notified of important changes on your website or app. They are a great way to save time, but they also spam your mailbox quickly. Defining good custom alerts takes therefore time and requires some preparations. Here are recommendations on what you should focus on to only get the right alerts at the right time.

  There are several questions you should ask yourself before you define a custom alert :

  1. Do you really want to be alerted ? If the answer is no, then do not use this feature.
  2. What is the level of this alert ? Not important, interesting, highly critical… if it is not highly critical, do not define an alert for this. Probably the emailing report or custom reports feature will be a better fit.
  3. How would you like to be alerted ? SMS, email, sound, homing pigeon (unfortunately we do not support this feature at that time). If you are looking at your emails once a week, then defining a daily email alert won’t make sense.
  4. How would you like the alert to be named ? Give your alert the most explicit name, that’s the first information you will see when you get alerted.
  5. What will be the next step once the alert is triggered ? If you cannot find any action once the alert is triggered, then probably an alert doesn’t make sense.

  Once those questions are answered, you can start configuring custom alerts. There are many alerts you can define but as just mentioned, which alerts you should create always depends on your goals and what is critical to you, or your business. Let’s look at some custom alerts that we see quite often.

  No visit

  One of the easiest custom alert to define. You probably want to be alerted if your website did not receive any visit. As this alert is highly critical, you will want to receive an e-mail, even an SMS. This alert will trigger only if the number of visits is below 1 on a daily basis :

  

  Here the action we will take is to have a look at the website in order to see if it is still live. If the site still works, we will look at the tracking code in order to see if the website is still correctly tracked or not.

  Convinced of this custom alert ? Let’s look at another example.

  Target achieved

  Let’s say you gave a goal to one of your employee to reach a specific threshold in terms of conversions. You can then define a custom alert in order to inform you when the threshold has been reached.

  You can simply do this with an alert saying “Target achieved by Franck” where number of conversions equals the number of actions you defined with him. It takes you only a minute to define something you would have missed otherwise.

  

  Here the actions we can think of are either to congratulate Franck or to ask him what is going wrong if the target is not achieved.

  Did you know that you can also take advantage of Matomo premium features to define custom alerts ? Let’s see one of them.

  Lost SEO ranking

  If you are using the Search Engine Keyword Performance premium feature, there are really interesting combinations you can use to create custom alerts.
  For example, you can be notified when a specific keyword lost or reached a position :

  

  You will be alerted when your website is losing some positions within the search engine results for specific keywords. Here the action we could take is to investigate why we lost a position on Google for this keyword.

  There are many custom alert combinations waiting for you out there. Why not giving them a try ? If you have any questions, feel free to ask them on the Matomo forums.

• Q&A : An interview with Matomo founder, Matthieu Aubry

  20 novembre 2018, par Joselyn Khor — About, Community

  Hey everyone ! Joselyn here. As always the views of our community remain top of mind. So to make sure you guys know the thinking behind these new projects, we reached out to Matomo’s founder, Matthieu, to ask questions you might want answered. Please check it out below !

  Hi guys, it’s Matthieu ! Here to answer some questions about the rebrand and the future of Matomo and Innocraft.

  What’s upcoming ?

  We’ve been busy implementing our rebrand into all aspects of Matomo and there’s also our new website, which is launching today ! The new website will help people better understand what Matomo is and how they can benefit from using modern web analytics.

  Why was Matomo and Innocraft brought onto one website ?

  In the past the separation caused a bit of confusion so we’re taking this as a chance to unite both the business brand, Innocraft and community brand, Matomo, on one website. Putting our focus on one brand, Matomo, makes it easier for people to see us with fresh eyes. We have a community side as well as a business side and while the community is still incredibly important to us, we find we have a powerful analytics tool that is capable of helping businesses too.

  Is Matomo becoming commercial or turning corporate ?

  No. nothing is changing. Matomo is still an open-source project and community. Although we’ll have a pricing page and “start free trial” on the new website brought over from Innocraft.cloud, the Matomo community will still play the biggest part on the Matomo website. We have dedicated sections focused on Community and On-Premise.

  The rebrand exercise helped us gain a refreshed perspective. After reflecting on how far we’ve come, we can feel more confident about Matomo Analytics itself as a platform. We believe it’s a great chance to bring that confidence into the brand and vision. We are proud that it’s an awesome open-source platform and at the same time it’s also powerful as a tool for businesses.

  Why is there no ‘download for free’ button on the homepage ?

   

  
  We feel many users coming to the site will get confused about our hosting options (Cloud and On-Premise) which is something you don’t usually consider when choosing an analytics tool.

  The reason for us to not have that button is when people see a “download for free” button on the homepage next to a “try it for free” button, it creates confusion. For those who do choose to download Matomo often become confused when they are left with a .zip file unaware how to install it and the technical requirements of self-hosting. We feel presenting our users with the simplest installation option first will give them the best chance possible to try Matomo to its full potential, without cost.

  And you can still find the link to Download Matomo in the footer of each page.
  

   

  Is Matomo still free to download and have forever ?

  Absolutely. The free open-source download can be found on the On-Premise section of the website, or download Matomo here.

  Why is it important to have a business behind the project ?

  There’s the reality that we have to make money in order for the Matomo project to survive … and thrive. The reason we still need a business side (Innocraft) is to fund and sustain the Matomo project. Whenever people purchase premium features, this helps finance the development of Matomo for our community.

  Because of the business we’re able to continually maintain and develop Matomo for you guys as well as future users. For example, the next release Matomo 3.8.0 is already mostly developed and will bring lots of interesting features too, like the two-factor authentication, Brute Force Protection, failed tracking requests reporting, lots of JavaScript tracker improvements, a new total summary row below reports, and many more security fixes, bug fixes, and other new features.

  So we see a business being very helpful in supporting our open-source community. Without a business side, our free, open-source project would not be able to survive.

  How will you protect the Matomo project ?

  We’ve ensured the Matomo project will be protected for the future as we wish to turn it into a not-for-profit foundation.

  We’ve also got a safeguard where the open-source code will stay under a GPL license forever. This is so we can guarantee, that no matter what happens, the Matomo project itself will stay completely free software.

  Is there a way for people to help ?

  There are heaps of ways to help ! You can help other Matomo users in the forums, contribute to fixes on GitHub, leave a great review (e.g. alternativeTo), help look for bugs with our Security Bounty Programme or participate and spread the word about Matomo in our community social media pages – Mastodon, Facebook, Twitter. Telling your friends about us would be very helpful too !

  What’s planned for the future ?
  We’ve worked hard to become the #1 open-source analytics platform (1.4 million websites use Matomo today), but now we need to empower even more individuals and businesses to take back control of their own data.

  Showing our community that we have a powerful platform is crucial, but alongside that our values are what define us. User privacy is still of utmost importance and we’re here to make it known that power needs to rest in the hands of people and not large corporations.

  You can rest easy knowing you’re doing your part in using trustworthy and dependable tools. By joining many other companies who are growing this movement to decentralise the Internet, we can build a safer, online world together.
