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.

Cyber Security Comics?

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.

The first one is Super Smart Security Novel:

Technology in 2017 & trends for 2018

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).

IBM offers (if you don’t mind sharing with them some personal information) free download of Blockchain for Dummies.

What’s next in 2018? We will see… But according to website trends in 2018 are: Artificial Intelligence, IoT and SDE – Software Defined Everything.

Wish you a succesful and futuristic 2018!



News: Windows Mobile hotspot?

Recently I got on-screen notification from Microsoft that they recommend Windows update to newer version because version 1507 will end its support for security updates.

Subnetting: engineers hidden secret

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.

Patch cables

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.

IT career – good example of CV: Elon Musk

Recently I found this amazing article on Business Insider, it’s one page long example of Elon Musk’s CV. The good thing about this CV is that is short – you see everything he does concentrated in this one page, it’s full of useful information: such as past projects, recent projects and skills, languages, education.

Spring/Summer plans? On-line courses!

Another thing I love about free time its ideal to start a new project and keep myself busy, that’s pretty much how 24itworld started.  I wanted to do something new and share my passion about tech. But after a while I used all my aces in the sleeve. How to expand your IT knowledge to the next level? I mean yeah we IT people share our tips and tricks on-line on forums or by the coffee machine in the office, but let’s be honest that’s helpful but not enough.

Cisco Packet Tracer Software

So on-line courses during spring or summer are ideal solution to learn new tricks, start new project and maybe to meet new people.

IPv6: time for transit?

There are currently three operative technologies for trafficking packets in IPv6. The main question here is, how to developed system that can be used on IPv4 and IPv6 applications on existing machines? This means that for example if you have server running on IPv6 that can communicate with IPv4 clients or vice versa. This might sound like a simple problem to solve, but complexity is much bigger. You can solve that kind of problem with additional hardware upgrades or software solutions – however this solutions and development doesn’t come cheap and it takes some time to put it in production.
