Friendly IoT or Daemon of WarGames

Is the Internet dangerous? Well, yes, we know all the hazards of spending all the work hours behind monitor screens, browsing the web at home, doing social networking, playing online games, watching YouTube, staring at smartphone little displays, or for whatever reasons we sit above our keyboards most of the time every day. That's indeed what we first think of—all the negative aspects of the mighty global network—but today I am not referring to all the potential medical issues inherited from sitting too long on the chair or looking every day into the LCD screen. I also don't mean the obvious social and/or physiological outcomes from letting the virtual world take over the real one for more and more people every day. No, I mean the real danger. Did the Internet overcome the pure network system and become a tool for mass destruction or a background tool for criminal activities? Can someone use the internet to hurt somebody or to perform a murder? Either directly or indirectly? Can some organization, country, or corporation use it to start a war? I mean, wars in the past began by more trivial things than by one global network. There was one war in the year 1969 between El Salvador and Honduras, initiated by a football game. True story. Google it.


You can relax. The Internet is still far from being a player. Or a rifle. It is getting sophisticated by the day, but currently it is still lacking two things to become something more than just a network. Two things are in development as we speak. And yes. You can stop relaxing now. The Internet IS going to be potentially capable and very dangerous when these two things become reality in the future. Very near future, if you ask me. And one of those two doesn't even have to be perfect. Like any other internet thingies, they have cool acronyms. AI and IoT. The first one will provide internet to be self-aware... or... in simple words, to start thinking. It means 'Artificial Intelligence', of course, and even though current development is far away from creating a real replacement for a human mind, some sort of NAI (near AI) will be sufficient to act independently on many occasions. NAI is not real AI. It is rather a complex logic that emulates thinking behavior in some spatial scenarios with predefined and predicted all or most of all directions and events. For example, the current two operational robotic rovers on Mars, Curiosity and Opportunity, are capable of driving on their own with their operating software. Or here on Earth, many metro systems in large cities are operated by complex control and are fully automated, without humans behind train controls. Something like in this embedded video was unthinkable only a couple of decades ago.

To be honest, true AI is not really a real threat. Even if science and technology build an AI entity tomorrow with certain doses of emotions and reason, it will be just another child in the neighborhood. True danger in the background of the global worldwide web is only the programmer's anticipation and powerful IF-THEN-ELSE command. And we have both today. AI being a mad mastermind of the future is not needed. The only thing preventing the Internet from being dangerous today is the still-early phase of IoT. "Internet of Things". Think of it like this: if you have brains and no body or senses, you are as good as a conductor without an orchestra. This is the inevitable part of the future Internet. It will get a body and a wide variety of sensing abilities. Basically, until now, IP addresses were reserved for devices with brains, or CPU units if you will. Home computers, business servers, phones, tablets, smart TVs, and microcontrollers are happy units today with internet access and proud owners of IP addresses. The trend is for tomorrow that all technology-based devices get online too. Remote controllers, motion sensors and any type of sensing converters, home and kitchen appliances, cars and any type of vehicle, industry tools, medical sensors, 3D printers, clothing items, and literally anything at all will be able to get a 'smart patch' and be allowed to be monitored or controlled over the internet. Think of this futuristic network from today's Google and Android smartphone perspective.


If you are a user of Google networks and devices (like I am, and this is just an example; the same goes for other providers and internet giants), from their databases (and I am not saying that they are doing it), it's possible to know what you are browsing to the simplest detail by your usage data in searching the net and the history of your browser, who you are following on social networks by which timeline or wall pages you are opening the most, what you like and dislike, what your watching habits are by your YouTube statistics, how your life looks in writing by your usage of Blogger, and all your whereabouts of your Android smartphone by Google Timeline. Not to mention that they have access to all of your online photos, videos, and files through your usage of all of their services and cloud storage. Oh, yes, and they have all your passwords you typed on various websites. Google is not even on the top of potential 'smart' providers with access to your, well, everything. If you are a user of, for example, Microsoft or Apple and their operating systems, then they are able (and again, I am not saying they are doing it) to know and have access to your localized data that is not clouded online. The story continues into the business environment further. If you are the proud owner of a rack of servers in some cool data storage building and you didn't write all the software and used so-called 'third party' code, the simple fact is that you are not the only one with potential access to all of your racks. And you are not the only one capable of monitoring all the network traffic. Those who manufactured network cards can do it too. Again, I am not saying that big internet corporations are doing all those spying and sniffing of people and other entities online, just that if they wanted to, it would be technologically possible.

Anyhow, all the worries of today's digital world end with privacy concerns. If you are a villainous criminal or a mad hacker, all you can do is steal somebody's identity data and log into other people's accounts for whatever malicious reasons you would do that, but you can't physically and directly harm somebody. In the past I have had these encounters with online thieves, and one of them cracked my password, logged into my dial-up account, and used free internet for a while until I went physically to the internet provider and overrode him for good. After that experience, I am creating complex passwords, and on a couple of occasions, they are so complex that even I forget them after a few weeks. I guess now is as good a time as any to thank all those "Forgot your password?" links standing timidly next to login forms.


However, the Internet of Things will have the power to end all of those 'benignities' of today's online world. Smartphones will not be the only systems with a 'smart' prefix. I am imagining all the varieties of SmartHomes, SmartCars, SmartShips, SmartRoads, SmartOffices, SmartFields, SmartTraffic, SmartEnergy, SmartPolitics... Ok, let's not push it. Some things will never happen. Nevertheless, and seriously speaking, even though this post looks like I am against the future breakthrough in the Internet size and means, many of the IoT-based gadgets will be extremely helpful. Think of the future SmartForest with many embedded fire sensors and intelligent surveillance cameras or SmartHealth gadgets actively monitoring your health signs and alarming anything potentially hazardous, either from within your body or by sensing bad food or air or any type of toxin in your near proximity. Surely every bright medal has the opposite side, and with the possibility of accessing all the gadgets online and controlling them from a distance, I am more than positive that we will be facing SmartViruses as well, and still, just people's passwords to access their mailboxes or bank accounts will be completely dwarfed by the online crime of entering somebody's house system and starting to leak gas while everybody is sleeping.

I am not quite sure that the Internet of Things will exactly be "The Fourth Industrial Revolution", but in one way or another, after a decade or so of transition years, it will be our everyday reality, and the next generations will embrace it and take it for granted just like we do with our current technological surroundings. Or our fathers and grandfathers and their lives within old-fashioned telegraphs, radios, and CRT television sets. Or their fathers and grandfathers with newspapers and books.


Anyways, we will be dealing with IoT when it happens, and I am sure I will be writing about it in general or in specifics on this blog or elsewhere in the future, but today I only want to end this story with a recommendation of one great related novel. About thirty years ago, I was watching WarGames on one of my first VCRs, and it instantly became one of my favorite films. I was more or less the same age as Matthew Broderick back then, in the middle 80s, when he played the lead role in the movie, and needless to say, I spent numerous hours watching it again and again and even read David Bischoff's book based on the original screenplay and enjoyed it all the same. At least for me, it was definitely an influential book of the decade. Every now and again in the previous thirty years, after WarGames, I was wondering why no decent book or movie was made to represent the real successor of the original story only in the realm of nowadays' Internet instead of WarGames' military background. And after three decades, finally, last week, on a friend's recommendation, I purchased Daniel Suarez's "Daemon". In the 'book' thread of the blog, I reviewed many titles without much of a spoiler, and to continue in the same fashion, all I can say is that it's one of those books you hate to leave, and as I am very close to the end, I don't see what would happen to force me to not give it a full five stars. "Daemon" is exactly what I was expecting after WarGames. I read that Walter F. Parkes, co-writer of the original WarGames screenplay and producer of the Man in Black movies, was interested in producing the movie "Daemon" and its sequel, "Freedom" (or "Darknet" in some editions), but this is still in "the clouds", probably due to the extremely technical plot and twists. Perhaps "Daemon" is more suitable for a mini-series or sci-fi TV show... Time will tell.

As for me, my time in the near future is locked and reserved for "Freedom", eagerly waiting in my Kindle's memory. With the same enthusiasm, I am embracing a not-so-near future full of "Internet Things" and what they will bring to our technocracy.

Interview With an Expert

Have you ever thought about the most common software application installed on your computerized devices in your home? Is it some super tuned operating system you can't live without? Or is it some sort of office application you use to write, make presentations, and connect with your friends and business acquaintances? Maybe it is your favorite browser you are using on a daily basis to connect to your social network? Or some photo gallery application with tons of your digital photos and video clips? Perhaps it is some Skype-like communication device that is always within reach? Whatever it is, and depending on who you ask, I am more than positive that there are no unique answers.

Microsoft's HoloLens

I am sure everybody knows (?) why they are so fused to computer screens these days, but in our case there is no doubt. In total sum of our digital home appliances that can be found on various desktops or fit nicely in our backpacks or pockets, the most dominant cross-computer application is Minecraft. That includes a couple of Androids and Windows Phones, various personal computers, and one Xbox console. Not only that, we tried the most of Minecraft installations, maps, and mods, but we are also hosting a small server with our own growing world. Well, by 'we', I surely include myself with a teeny-tiny share in the plural meaning of the world, but the majority of the 'we' belongs to Viktor, who is our in-house expert for Minecraft affairs.

But before giving some thoughts on the Minecraft game, I asked our expert couple of questions in hope of understanding why one not-so-graphically demanding application and one not-so-typical game that requires not-so-much-of-real-gamer skills when it comes to quick interaction between the characters and other players is so popular and truly became a worldwide phenomenon and won so many awards over the years.

In-house expert for Minecraft affairs in action

Following is a short interview with me asking questions and Viktor answering them. To be honest, I am not really that familiar with all the Minecraft world; let's face it, over the years it grew into a full internet movement with MineCon and everything, so I hope my prepared questions are not off-the-topic or old, rusty, and non-interesting.

Anyhow, I will be taking that risk, and here's the full interview between father and son and more than 30 years of generation gap in between:

When did you learn about Minecraft, and how did you feel playing it for the first time?
At first I didn't like it that much, but later, after I watched "The Asian Guy Gamer" and their Minecraft videos on YouTube, I bought a Minecraft disk for Xbox 360 and started making my own worlds. I am playing it almost every day ever since.

Why do you like Minecraft so much and how is it different from other games?
Because I can build things and make my own worlds. Also, there are so many worlds out there, and every game can be different, and I can do whatever I want.

What do you like the most in the game?
To search and mine diamonds and make armor, swords, tools, etc. To build large houses and castles and to play within online servers.

How would you rank Minecraft installations and why?
1. PC 2. Xbox 3.WP 4. Android. PC version is the best, simply because I can play in multiplayer mode with my friends online. It also allows typing commands and cheats. And I have a server of my own with my IP.

Who are your favorite characters and skins in Minecraft?
Hulk and Foxy for skins and Ender Dragon for characters. Horses in Xbox are also great.

What is the most complicated structure that you ever built?
Roller-coaster in PC and large, eight-story house in Android game.

Who are the best Minecraft gamers you are following online?
Definitely Pat and Jen, Channels: PopularMMOs & GamingWithJen. Also Think's Noodles, The DiamondMinecart, and Stampy.

If you could, what would you do to improve Minecraft in the future?
I would like to see portals between servers somehow. So I can make a portal on my server that ends on some different server. Also more interesting machines.

Which one do you prefer: Creative or Survival mode?
Survival.

Is Herobrine real?
Only in some mods.

Well, there you go. I can't be completely sure, of course, but it is pretty certain that if you asked any other seven-year-old Minecraft gamer, you would get the same answers. More or less. However, this game attracts players of any age. I was no different. I remember when I turned it on for the first time, and after spending half an hour in the tutorial, my first reaction was "What's this?" followed by "What should I do now?". And then I realized. This is not the ordinary game. Like most of the other games, where you clearly know what to do and what your goal is. No, here, there are no goals and there are no levels. There is no ultimate ending you are reaching toward. The only thing Minecraft is giving you is the environment. The rest is all yours.

Creeperized Wallpaper for true Minecraft gamers

As soon as I figured that out, it was pretty obvious that in order to turn the game on, you have to deal with two switches. One is to click on the icon to start the game, and the other is in your head. The one that says "Imagination Power On". So I clicked on that one too, and everything started to make sense. The next thing I knew was that hours passed in the real world while I experienced a truly great and short entertainment inside. In a nutshell, Minecraft doesn't require some expensive VR gadget to render the world for you. It does all that with elementary graphics and ordinary three-dimensional programming. What it is extremely successful with is the interaction with that other switch in your head that makes everything possible. Very few games are capable of such things, and this is the main reason Minecraft has been so successful for so long. For that matter, I have fears for the direction of future Minecraft and the vision in Microsoft in order to use it inside of their version of Google Glass, called HoloLens. I surely understand the need for next-gen gadgets and that VR is always trying to get into gamer's worlds effectively, but in this particular case, it could destroy the very essence of Minecraft imagination. I am sure that HoloLens, when it comes or in one of it's future versions, will effectively merge the real world with the imaginary one and, in this case, perfectly render the Minecraft world into your living room. Imagine that.

But is this really necessary?

Maybe.

Perhaps not. Playing imaginative games like this one is just like reading books. You don't need extra help to render the virtual world. You have the ultimate gadget already. For free.

The little gray cells.

Scientific Copenhagen

Do you have that strange feeling when you are about to visit a new city abroad and are a little afraid of what you will stumble upon when it comes to simple things? Like how to use the metro line or how to buy a bus ticket or how to identify your next destination? Or how to book your flight back to your home? Or how to handle a simple dilemma: should you exchange the money to the local currency, or is it wise to put your card in every ATM or any other 'slot' machine on your way?

Hello™ at Microsoft Campus Days, 2014

Ericsson, a Swedish multinational provider of communications technology and services, has the answer for you. And me too. Last week, I took my entire family on the trip to Copenhagen for both business and pleasure hours in the Danish capital. During my previous visits I didn't have much time for tourism or any off-work activity for that matter. So I did a little research this time, and Ericsson's "Networked Society City Index" helped a lot. With the well-developed ICT infrastructure, economy, and social development, as well as environmental progress, Copenhagen is located in the top five within the NSC index, among 31 well-developed worldwide cities. After our visit we left Denmark with a feeling that everything, or most of it, went perfectly smoothly and the applied IT was extremely helpful, simple, and useful. Unified communications (UC), integrated into people's business life from within smart gadgets and laptop computers, were also a big part of it, and I can proudly say that, in a way, I took part in the active development of Rackpeople's* Hello™ for Microsoft® Lync®—UC software that integrates with Microsoft's Lync and Exchange and presents video conferencing within a single click on a wide variety of screens and devices. The business part of last week's Copenhagen trip was to visit Microsoft Campus Days, where Hello™ had a big feature presentation and successfully presented what it can do in the current edition. From the developer's point of view, I have a good feeling that this project will have a long life with plenty of room for more versions in the future, especially if Skype and Lync integrate and create space for non-business users as well.

However, Copenhagen, besides the business side of the medal, has plenty more to offer. History, arts, sport and music events, amusement parks, museums, royal and naval sites, shopping streets and malls, restaurants, walks along the canals, sightseeing from the sea, and many more, but this time we chose to glimpse the city's unique scientific side. With a seven-year-old boy in our small family, along with me being a big fan of science and skeptical of society, our stay was really special. If you add last week's Black Friday hysteria, which brought an enormous smile on my wife's face all day long, I can safely say that we spent one of those memorable times you never forget.

The Rundetårn, a 17th-century astronomical observatory**

The very first day we went to see Rundetårn, an almost 400-year-old observatory built by King Christian IV after the first major success of naked-eye astronomical observation of planetary motion, performed by famous astronomer Tycho Brahe. His incredibly accurate measurement of 6 planets motion at the time was used by Johannes Kepler after Tycho's death in 1601, and for the first time in astronomy, three laws of planetary motion were established, including the one that all planets in the solar system move in elliptical orbits with the Sun at a focus. Even though there are still suspicious thoughts about honest relations between Brahe and Kepler and even uncleared circumstances related to Tycho's death (traces of mercury in hairs from his beard were found in the 1901 autopsy), these two colorful characters of the early 17th century made crucial contributions to our understanding of the universe, including the discovery of Newton's law of gravity, which was a direct outcome of Kepler's laws.

Anyway, the Round Tower in the heart of Copenhagen is still active and one of the oldest functioning astronomy observatories. The dome is 6.75 meters high and 6 meters in diameter and contains a refracting telescope with 80–450x magnification with an equatorial mount. Without an elevator or stairs, walking up and down its unique 209-meter-long spiral ramp that spins 7.5 times is something special I never saw before. Not to mention we had the opportunity to look through the 'scope with two very friendly astronomers who warmly welcomed us and patiently answered all the questions we had.

Apollo 17's moon rock

The next stop in our astronomy tour was the Tycho Brahe Planetarium. It is located not too far away from the observatory and hosts 'The Space Theater' with a 1000-square-meter dome-shaped screen, and seeing a giant 3D Earth rotating in front of you or 30+ meter high mammoths in "Titans of the Ice Age" is the experience you don't want to miss. They also hosted an "A Journey through Space" program and permanent exhibition with meteor specimens and one of the largest moon rocks from the Apollo 17 mission (in the above image).

Science is not science if you don't experiment in the lab, and to have at least a feeling of what scientists do on a daily basis, you have to visit Experimentarium City. The main exhibition last week was "The Brain", with tons of posts waiting to be explored and played with. Needless to say, my favorite was the game with the cool name "Mindball"—in which you have to push the ball only by using brain wave sensors. The more you are relaxed and focused, the more it will get into your control and move in the desired direction.

Mindball—moving the ball with brain activity

If you like to have your brain scanned and to see which part is activated when you move fingers, or if you want to see really cool optical illusions, or to learn more about scientific facts and how stuff works, or to play memory games, or... simply to experience a great family time, visiting Experimentarium City is mandatory.

Finally, no trip to Copenhagen would be allowed to have the adjective 'scientific' in the title without visiting the national aquarium and the zoo. Opened last year, Den Blå Planet, National Aquarium Denmark, located near Copenhagen's airport in Kastrup, is something you would need to see to believe. Especially if you came from a continental country like Serbia. Equally interesting was the zoo, which went viral earlier this year when they decided to euthanize Marius, the young giraffe, because of a duty to avoid inbreeding, approved by the European Breeding Programme for Giraffes. Right or wrong, it is not mine to say, but we humans are responsible for the health of the animal life, and at least it is a good thing that there are scientific organizations that are taking the breeding of animal species seriously. Anyway, perhaps the best impression in both the wild animal and fish exhibitions, to me, was their climate-controlled environments—in the zoo their "Tropical section" with jungle climate conditions, and in the case of the aquarium, it's the "Amazonian region" with tropical plant life, strange-looking fish, and lots of piranhas.

The Little Mermaid

Finally, I want to thank all my coworkers at Rackpeople for having a good time on and off the office, especially Lasse, who invited us for a visit and gave me the opportunity to spend my yearly bonus in Copenhagen. Trips like this are also a great opportunity to learn more about the country and region you are visiting, and I mean not just about the sites, history, monuments, and other attractions, but also about people, hospitality, and friendship. Sometimes, the result is more than you hope for... sometimes less. Perhaps the best advice when you are visiting abroad, no matter if you are doing it as a pure tourist or within a business agenda, or both, is to leave high expectations at home. Nevertheless, Copenhagen is one great corner of the world, more than worthwhile to visit, and this scientific side I wanted to show in this post is something not many cities in the world can offer.

The Little Mermaid

I am wondering if is it possible to combine, in just one blog post, a short story about one country, one modern IT business, several great friendships, air flights, professional challenges, and friendly people everywhere you look. I know the answer is probably no, but I will try anyway. Let's start with an easy puzzle: if you thought of The Little Mermaid and Hans Christian Andersen, quantum mechanics and Niels Bohr, the famous Hamlet's "To be or not to be" in Shakespeare's old play, and amazing cuisine with cookies, pretzels, Carlsberg beer, and Legos? The answer, for a very few of you who didn't guess, is, of course, Denmark. One of the top developed countries of the European Union. According to the United Nation's first-ever World Happiness Report from this year, Denmark has taken the top spot, followed by Finland, Norway, and the Netherlands. When I first read about this, I was skeptical since happiness is a relative thing and I am sure all people in the world are equally happy and unhappy from time to time depending on daily moodiness and events that drive us.


The Little Mermaid

However, now after my second visit to Denmark, I tend to change all the skepticism and maybe better understand the global happiness or social happiness, if you will. According to the study, one of the conclusions could be this (and I am paraphrasing the report): "While basic living standards are essential for happiness, and after the baseline has been met by the majority of people, social happiness varies more with the quality of human relationships than with income." Simple truth with no simple explanation, but if you ask me, I think that the history of any society is deeply embedded into everybody's DNA, and as long as it is not filled with lots of conflicts, wars, animosities, and hard times, the better human relationships become.

Several years ago, around the time of the birth of my son, I started outsourcing for a Danish consulting company within a team of developers providing coding in the Microsoft .NET environment for various purposes. A very big number of Danish companies are using Windows servers and other client-server solutions for their businesses based on the Microsoft environment, and according to my humble opinion, I fit in nicely due to my expertise and experience in the field in general.

The Rackpeople Team

Actually, contrary to most other jobs, being involved in IT development, more than having various degrees and initial knowledge, requires the ability to change and learn the new stuff. The technology is changing rapidly, and after more than five years of telecommuting, when it all started with simple web applications, we are currently involved in more sophisticated technologies like Lync and SharePoint development, connecting them with the mobile world and providing the right information at the right time. All those activities are followed by financial subsystems centered around Microsoft Dynamics C5, equally challenging from one developer's point of view. I remember the days back in the 80s and 90s when developing business software was completely different compared to the present day. This is no one-man show anymore. The complexity of the IT support, consulting, and development reached a higher level of understanding, and I mean for both sides, developers and customers. Even though I am outsourcing about 1600 kilometers away from the office, this would not be possible without internet, daily communications, reporting, solving puzzles, audio and video conferencing, brainstorming, and live meetings. The dynamic IT world is also affecting consulting companies, and five years is a very large period of time for all of us as well, so recently, as a result of last year's merger, the old/new company continued joined efforts within new surroundings and teamed up for future challenges.

Not so long ago I visited my friends at Rackpeople for a couple of meetings and some other on-and-off work activities in regard to future projects and also for simple socializing with the guys and some brainstorming sessions in a local brewery house (where else do brilliant ideas come from?).

Baltic Sea between Poland and Denmark

Of course, like any business trip, the best part came after work hours, where the office environment was replaced by the "Custom House" restaurant and an "ice cream" walk along with the brewery house in the 17th-century Nyhavn district at the end of my visit. This is part of Copenhagen you don't want to miss. I still can't choose what was the best: American classic steak, delicious ice cream in domesticated cones, or perfect draft beer. Regarding the whole event from a sightseeing point of view, what maybe impressed me the most was the sun still standing very much above the horizon while the local clock tower was showing 22 hours and a change. It was the cost of living on a round Earth so much north away from the equator. I enjoyed very much the sightseeing while driving through Copenhagen, visiting the famous Little Mermaid, and most of all our talks about lots of different topics. With this blog post I would like to thank Jesper, Claus, and Mark for an amazing evening.

I am not a frequent flyer, but every now and again I am using air traffic, and maybe now is my chance to write about my experience flying in a south-north straight line between Belgrade and Copenhagen. This last flight was pretty much smooth without much turbulence, probably because the weather was more or less the same during the whole 1600km long trip. However, two years ago I was taking the same flight during the hot summer, and the weather wasn't the same in the beginning of the flight compared to the last half hour and the descent itself. The moment the plane entered the Baltic Sea from continental Poland, the weather changed dramatically for the worse. I remember I was having a wing seat and saw the jet engine start seriously vibrating up and down. It was pretty scary, but the crew did not pay much attention, so I reckoned it was pretty much normal. The other travelers weren't so calm, especially one older lady that had to use the oxygen mask after landing, which was also a little disturbing, as the plane needed to take a couple of sharp turns at very low altitude in order to align with the runway. One more thing also attracted my attention, and this is how clean and spacious the Danish capital, suburbia, and small towns in the countryside are. Due to lots of rain over the year, everything is green and very compelling.
