The Internet of Things Is Here

The Internet of things… sounds interesting. Smart cities, smart homes, smart cars, smart everything.

It’s estimated by 2020 there will be 50 billion objects connected to the internet.  The current internet protocol, IPV6, creates more potential addresses than there are atoms on the surface of the earth.

How it Works

  1. Sensors that transmit data are embedded in the physical things around us.
  2. This data may be processed locally in the individual devices.
  3. If the data is too large or the device is not connected on the internet, it is stored locally.
  4. The next level is networking, where the device is connected to the internet. WiFi developments are making the internet of things work better.
  5. Cloud processing with more power than local processing, where data from different sensors is processed and analyzed.
  6. And finally cloud storage where processed data is stored to be consumed and used in different applications.

As these intelligent systems of devices share data and analyze it over the cloud, they are transforming our world in countless ways.

  • monitoring the weather
  • monitoring our personal health
  • giving real time updates on where to park our cars
  • IoT on cars and streets to facilitate rush hour traffic
  • smartphones, tablets, smart TVs, smart refrigerators

Yes. The internet of things is already in effect. There are so many startups. Very many ideas and projects in our colleges and universities. Big corporations are investing billions on IoT. And I really look forward to how this could save lives, especially in health monitoring and emergency services.

IoT will come with security issues. Yes I love IoT, but this part gets me a little bit terrified. Technology that you may not even be aware of is monitoring your every move. I once made a video on this but I was threatened so I scrapped it off immediately. Anyway it’s no secret that I am an optimist.  I don’t want to talk about many DDoS attacks and creepy children toys. The internet of things can be a weapon of  mass destruction.

Next week I’ll tell you how easy or hard it is to take over the world. How we can eliminate this situation where access to health depends on income, monitoring climate, technocracy and privacy, one of the big societal concerns.

Let’s talk tech!

Prime Number Magic

Math is central to our daily lives. This is a fact, whether you love it, hate it, or don’t even understand it in the first place.

Numbers are weird objects; and I’m particularly fascinated by prime numbers.  A prime number is only divisible by itself and 1. Another mysterious fact is that every even number is the sum of two primes. Today I’ll talk about an algorithm, as an example of how math is crucial to our online security.

As a mathematician I love algorithms; instructions that solve problems. Algorithms are ancient. As much as I’d talk about technology, they are not exclusive to the world of technology. The first algorithm was to find the Greatest Common Divisor(G.C.D) of a number. One modern algorithm you may have heard of is the Pagerank algorithm by Larry Page and Sergey. If you’ve not heard of it, then you’ve used it. This is the algorithm used to rank web pages by Google, the world’s leading search engine. Creating algorithms requires a lot of creativity and genius. It’s no surprise only a few come up with world-changing and award-winning algorithms.

Now, back to prime numbers. E-commerce and the internet wouldn’t be safe without these special numbers.

Banks, websites and other systems use the RSA public-key encryption algorithm to keep our internet secrets. RSA are the initials of the people that came up with the algorithm; Rivet, Shamir, Adleman.

RSA encryption is achieved by producing a public key and a private key. The public key is two massive primes multiplied together. The public key is available for anyone to use.  If you want to decode the secret key, you need to know the original prime numbers. The only way to do this would be to take that massive number and factorize it. This is impractical with current technology. And this is how prime numbers uniquely secure our information.

This is just an example of the many ways math impacts our lives and an application of prime numbers. If you love cryptography and code cracking don’t go far as more is coming. Let’s talk tech!

This is My Passion

It’s Ancentus again! First of all I thank everyone who has been following this blog when it’s been up and when it’s been down. And especially those who have inspired me to resume writing. I came to the realization that I could give my story today and hopefully inspire some people. I’ll talk about how I’ve realised my passion and inner awesomeness!
Passion makes every minute of my life counted and valued. My passion is about science and technology. Something I’ve had since childhood, but which I only discovered while in high school.
I spent a quiet early high school life confused by religious beliefs, history and the existence of life in general. This did not hold me back though. Physics and Computer Studies were my favorite subjects. I focused on what I liked and it didn’t take me long to realize that I was awesome. Since then I came up with exciting challenges and goals which helped and are still helping me a lot. These include:
-typing speed challenges.
-using the computer without a mouse. Helped me achieve fast coding and debugging skills.
-writing a program every day. I am now advancing this challenge to include AI in my daily programs.
-reading tech news daily. My goal is that I be the one writing daily tech news.
I believe I have now fully realized my awesomeness; designing, writing and coding guided by three principles:
1. Sorrounding myself with encouraging people.
2. I know what I want. Money has never been my motivation. And if it was, believe me I wouldn’t be in school now. I have had poor concentration since I was young and tend to fantasize a lot when listening to a teacher. I’ve never taken that as a weakness as my imaginations and fantasy help me realize what I want. It is during such moments that I get great ideas, some realistic and others unrealistic.
3. I take my coffee seriously. Late into the night debugging code, working on a project or doing my artificial intelligence research. I try to learn something new every day and this is what is helping me develop myself and keep up with current tech trends.
Living my passion has helped me get some expertise skills up my sleeve. These include mobile, desktop and web application development, algorithm design and development as well as robotics. My first AI related program was a simple mock-up of an intelligent assistant. Check it out at https://www.youtube.com/watch?v=rPnszq7cv7I&t=20s My first AI program was a supervised AI program simulating a soccer match, which I wrote in the Java programming language. It was a good challenge for me as I came up with ball possession and goal-scoring algorithms using simple probability. Everything comes with challenges and my biggest challenge currently is balancing what I do with my mechatronics course work. Anyway it’s all science and technology so I’ve gotta get down to it.

This is my passion. Tech is my passion.

Artificial Intelligence

The Promised Life of Intelligent Machines

If there are terms in this article which you may not understand, it’s advisable to read it from the Ancentus Tech app so that you can ask Techie bot to define them for you. Get the android app at https://play.google.com/store/apps/details?id=com.ancentus.tech

I don’t want to talk abut the future. I want to talk about now. I don’t want to talk about AI fiction. I want to talk about the AI we have now. Since the term Artificial Intelligence was coined in the 1950s, many predicted that this will be a century of intelligent machines and technology. Are we living that life?
There has been a wide talk about the dangers of intelligent machines and scientists being worried about them. I won’t go into that now as it is more an issue of the future. But I want to beleive that they would be our friends, the same way I would not think of my best friend turning against me. It’s all about how we make and use them.
I first noticed AI in advertising 4 years ago, when I was 15, while browsing on a home computer. I noticed that most ads displayed were within my interests. That is what we call machine learning. You may also put it under cognitive intelligence, which is all about our needs, wants and behavior, which machines are able to mimic. Advertising is not only about a catchy line or a creative design. Marketers are now facing the challenge to give the customer what they want. Most agencies are taking this challenge and using insights from cognitive intelligence to create personal experiences to clients. Look at Facebook, for example, among your friends, whose posts appear most on your feed? There must be some AI there, right?
Siri, OK Google, Cortana, Amazon Alexa… You must have come across one of these and other bots in your device. These are Intelligent Personal Assistants; which can perform tasks or services for you. I personally love chatbots, especially those that are able to predict my intents, of course without digging into my privacy. All this is artificial intelligence at your service.
Many corporations are currently racing to put self driving cars on the road. Google is actually facing stiff competition as other companies whose core business is autonomous cars have come up. Most of these companies are looking to hit the road by 2020, so we may call the next decade the promised life of autonomous cars. I wont talk much about them for now, but if I got the chance to ride on one, I cant fail to brag about it, believe me.
In robotics, AI is the most controversial field. It has become hard to define Artificial Intelligence, just like the term ‘robot’ itself. We have robots automating manufacturing and other processes in industries, but are they intelligent? As much as most of them have a mechanical construction and electrical components, I would still put industrial robotics under AI as they contain some level of computer program that determines what, when and how they do something.
If you now feel like you want to join the revolution, I’ll give some information. Common fields of artificial intelligence research are expert systems, neural networks, robotics, fuzzy logic and natural language processing. Fortunately, there are many doing research on artificial intelligence, so we can just make use of their products. If you are a developer, for example, you have Google’s TensorFlow which is now open source. TensorFlow is an open source software library for machine learning in various kinds of perceptual and language understanding tasks. Google also has a speech API which you can use in your applications. You may also decide to be like one of my friends, learn programming and focus on writing smart algorithms.
We can all be part of the AI revolution in one way or another. Let’s embrace what artificial intelligence has for us and transform our world to a sophisticated technological marvel while we still have it. We are living in the promised life of intelligent machines, and there is no going back.
