Idea: a Smartphone based generic scan app for IoT

There is a fundamental problem in managing Internet of Things (IoT) sensors. IoT sensors need to be of the smallest possible form factor as well as be designed to optimise battery life. Thus any unnecessary power use needs to be restricted as well as the sensor needs to have power hungry integrated circuits such as the radio in sleep mode when not transmitting. The result is that it is not feasible from a power and financial cost point of view to have a GPS sensor in every IoT device. What this implies is that the management of IoT devices become problematic as in a large eco-system the accuracy of where each sensor is located is non-optimal. the reason is that each device needs to have these details manually recorded by the installer. This also has problems as transcribing introduces further human errors.

easywall - Web interface for easy use of the IPTables firewall on Linux systems written in Python3.

Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

No Scrubs: The Architecture That Made Unmetered Mitigation Possible

When building a DDoS mitigation service it’s incredibly tempting to think that the solution is scrubbing centers or scrubbing servers. I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
