I have realized many projects based on webapplications. When you jump into this topic you tend to use XAMPP and there is nothing to say against it. To be honest, I still use this application. It is super easy and very efficient because you do not have to spend too much time with the configuration of your local server. But there is a very common failure many beginners tend to make: they do not use the full power of the tool.
One of my biggest problems is that I am having so many different projects. So if I do not write down important steps I tend to forget them and I have to find the solution again from scratch. Because I am doing this now for the third time I am now writing it down.
Communicating with a huge number of clients requires a simple, fast and reliable solution. Message queues seem to solve this problem in a very efficient way. There is a reason why many people treat MQTT as the "language of the Internet-of-Things".
Due to the limited ressources of our IoT-devices we should try to optimize our code, in case we do not want to wait long time each time we access our nodes. In this post I will present you some simple tricks how you can make your device more reactive. The actions are listed from very quick steps to a bit more complex tasks. (May I am going to update this post after some time.)
The last few weeks showed us that the Internet-of-Things can be pretty dangerous, e.g.: Mirai Again: DT Outage a Precursor to Larger DDoS Attack. Especially if the devices are able to communicate with the internet there is a high risk! But I think this is not the only hazard. What happens if someone gets into your network because of an insecure device? This posting will list some actions the possible of such an attack.
