I recently started doing some competitive programming and going trough advanced algorithms...not really a side project but i'm looking forward to make a Network Monitoring service something that runs in your computer and acts passively to monitor system changes... to protect against malware mostly . -My current side project isn't even 10% complete but it's on my scope I'm working on a micro virtual file system for important documents...due to the rise of Ransomware and people being lazy I think that making a secure,encrypted virtual filesystem could be a great idea . Those are my thoughts only
