Debian is one of the first Linux/Unix-based operating systems and it’s also used as a platform for costume designed Linux operating systems like Kali Linux etc. It’s a bit more complicated install full of different steps – the good thing in the whole story is that the install is guided but for additional reading I recommend this online manual: https://www.debian.org/doc/manuals/debian-handbook/
I’ve decided to share a short tutorial how to install Debian in Virtualbox. Afterwards I plan to play with firewall install a bit, but I will used that in next blog post. I need to google things around, but if anyone has an idea or suggestion which firewall to install feel free to email me at: firstname.lastname@example.org

Patrick Kua is CTO of N26. What is N26? It’s a online bank. We all have bank accounts and use banks, but N26 is interesting because it’s the first mobile first bank with a European banking license. This means this isn’t a traditional bank, this is the bank that offers classic bank services (like credit cards for example) – online. I think this is interesting product of the future. You can read Patrick Kua biography here and more about his cool skills and knowledge.
This are cybersecurity comic books or slide shows, how ever you prefer to call it, powered by Cisco. I came across this while surfing online and I think that is a fun share.
Graphic novels are written by Kevin Maney and artwork is by Mark Holmes. It’s not the same genre as famous XKCD – but it also captures recent reality of everyday life in the IT with a funny comic book spin.
I also added the Cisco’s slide show on Smart Cities, which is another interesting story in the world of technology right now.
It’s been a long year full of interesting things in 2017. I think highlights on the scene of technology in 2017 are …
Larger screens on smart phones – which is good and I love the futuristic design manufacturers are making. Since the official colour of 2018 is ultraviolet, the well know colour of cyberpunk, I think design in 2018 will get even more in futuristic direction.
Electric car development – beside Tesla, which is electric car only company, other well know car manufacturers are also selling electric cars. The story was also covered on Business Insider. That story of electric cars will probably follow in 2018…
And crypto currencies. Even The Guardian posted a story on the digital coin phenomena. What is the point of blockchain and cryptocurrencies anyway? It’s available for anybody in the world who has a computer and internet access. And there are stories online on co-called bitcoin millionaires like Winklevoss twins (that guy’s who sued Mark Zuckerberg because of Facebook project).
Tonight a short guide in the world of subnetting. What is subnetting? Well taken from Wikipedia it’s:
A subnetworks or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting.
So it’s like this we have hosts, clients and network stations. Hosts are usually main computers, servers or mainframes. Clients are usually computers from users. Network stations are switches, routers and other network devices. To make things work we connect this devices in to network that we provide information flow. Every device in ethernet environment has IP. We can configure this IP’s in logical network. We have different topologies, but that’s not relevant now.
Recently I found this amazing article on Business Insider, it’s one page long example of Elon Musk’s CV.
