THE INTERNET OF THINGS: The upcoming biggest tech trend in history explained in free, online courses


Encouraging students to study subjects they enjoy is always good advice.  Nevertheless, there are subjects that are so important in our education.Despite whether we enjoy them or not, we simply need to at least have some good basic understanding of them in order to have a smoother progression in life. One such subject is the “Internet of Things” (IoT) – its potential is extraordinary, it will be a basic key ingredient of life and work in the 21st century, and is touted to become the biggest tech trend ever.  Previous tech trends were generated by the introduction of personal computers and later, the internet.  IoT – is generating  a similar trend but at an incredibly far greater scale. It’s the new megatrend unfolding right now and is likely to reshape the world as we know it.


The Internet we use today is actually an “Internet of Computers (IoC)” which links up and allows communication between people, between computers, and between people and computers. The coming “Internet of Things” has an additional group of players linked to the system – i.e., “things”. This includes practically anything with an on/off switch.  In this new scenario, there will also be communication between “things” themselves, between “things” and computers,” and between “things” and people. By 2020, it is  estimated that the number of devices connected range from 26 to 100 billion.  It has been stated that the new rule of the future is going to be, “Anything that can be connected, will be connected.”


Connecting equipment, tools, and machines to the IoT network will make them smart.They will be able to respond to or be directed remotely by another “thing,” a computer, or a person.  Some examples of communication under the IoT scenario include:
·         Your alarm clock wakes you up at 6 a.m. and then notifies your coffee maker to start brewing your coffee ;
·         Your car figures out the best route to your meeting venue and takes it;
·         Knowing that traffic is heavy, your car realizes that you will arrive late and texts the other party notifying them of your late arrival;
·         Your office equipment knows it is running low on supplies and reorders more.


Discussions on IoT have been taking place all over the world as people try to understand how it will impact their lives.  People are also trying to identify and understand the many opportunities and challenges that will come up as more and more devices start to join the IoT network.

For now, the best thing we can do is educate ourselves about what IoT is and its potential impacts on how we work and live.

FREE MONEY FOR HIGHER EDUCATION: Scholarships for American and International Students


While studying at the University of Hawaii (UH), a friend told me how fortunate he was to be at UH. He did not apply for his scholarship till the very last minute, as he thought that there are so many students better than him and that he would not have a chance to get into the University.  He did not know that “everyone” was thinking the same negative thought - he was finally awarded the scholarship because he was the only one that applied.

It seems that the above incident is not an isolated case.  Christopher Gray found that each year some $100 million in scholarships go unclaimed while students drown in debt.  He confirmed that there is a lot of scholarship money out there. Through hard work and diligent searching, he landed himself a whopping $1.3 million in scholarships.

Gray came up with the idea for a mobile app to make things a lot easier for other students seeking scholarships. Later Gray teamed up with Nick Pirollo and Bryson Alef to become co-founders of what is known today as “Scholly” – a popular scholarship search platform.


“” recently made an assessment of 28 most popular scholarship search platforms in current use – including “Scholly”.  They found 11 sites not meeting their minimum criteria so these sites were not subjected to further assessment. They then carried out detailed evaluations of the remaining 17 sites which are listed below in descending order starting with the overall best. 

“Scholly” ranked  6th  and “Fastweb” was found to be the best site overall.  "Fastweb" is the easiest to use as it requires no registration to browse scholarship listings; it has both a searchable database and personalized matches; and is mobile-friendly.

“Fastweb” also has the most tools of any platform.  That fact, combined with a high score for scholarship availability, means “Fastweb” is the best platform for finding scholarships, managing deadlines, and tracking applications.


1)      Fastweb (9.3/10)
7) Sallie Mae (6.9)
13) Peterson’s (5.1)
2)      Cappex (8.1)
8) [TIE] Big Future (6.2)
14) Broke Scholar (4.6)
3)      Unigo (7.8)

What Else is New?


A recent report headline read: “You can now go to college for free in two of the most expensive places in the US” – referring to California (San Francisco city in particular) and New York.  Our response was, “What else is new?”  Free university and college studies have been  in the news a lot in recent years but have also been followed by one sort of problem or another.  For those thinking of relocating to take advantage of the announced free education, you should be reminded that your yearly income has to be at least $86,000 or $100,000 to live comfortably in New York or San Francisco.

Last year, a BBC report questioned whether free university tuition would work in the U.S.  The report pointed out that other countries use taxes to fund free university education  and have far fewer students than the US. For example, 2013 statistics showed that Germany had 2.7 million students in higher education and Norway had 255,000 compared to the US’s 20 million.

In response to the recent report headline above, some potential students may find it more appropriate to ask, “Wouldn’t it be better to explore free online courses or programs?”


Pros of an Online Education
·         Flexible schedule, as students can log onto the course material at their convenience, making it possible for them to keep up with other responsibilities;
·         Increased availability of programs, as more schools are offering online programs, increasing the available options for studies and allowing students to search until they find one that meets their needs;
·         Access to courses 24/7, as online courses are available round-the-clock to any student with a computer and Internet access, unlike on-campus courses that require students to be in class at certain times;
·         No need for relocation or travelling, as online students can study right from their homes, saving time, gas, and vehicle wear and tear. It also eliminates having to drive in inclement weather;
·         Multi-media format allows online students to learn through a variety of ways, including Web cams, CD/DVDs, animation and virtual classrooms.  This can make courses more interesting and easier to understand;
·         A wide variety of courses/programs available and students can choose to study almost any program online;
·         Students can log into their programs at their convenience and learn at their own pace; and
·         Reputation of online education compared to on-campus programs has continually improved.

Cons of an Online Education
·         Lack of social interaction among students;
·         Less student/Instructor interaction and students may have to wait for hours for a reply to questions;
·         Technology problems can interfere with students’ progress;
·         Without a teacher’s push, online students, may have low motivation and may procrastinate;
·         Transferring credits can be problematic as some schools still do not acknowledge online schools in the same light as on-campus schools; and
·         Financial aid is not available for some online schools.

MOOC vs On Campus / Carey vs Muth
In his recent book, “The End of College,” Kevin Carey explained how he had taken Prof. Eric Lander’s MOOC (see in REFERENCES below) and earned a certificate for completing the same work as that of a first year students at MIT. Carey did all the online class activities, also took the time to visit the class in real time – and came away convinced that online  courses is better because it allows him to:
·         Hit the pause button during the lecture to write notes in a more complete way than trying to write down words as they stream out in real time;
·         Concentrate on the class in a quiet place, such as the comfort of their home, instead of being distracted by the student next to him who is focused far more on their phone than what is going on in class;
·         Hear Prof.  Lander clearer; and
·         Clearly see what Prof. Lander does through multiple camera angles, instead of a far away view of him from the back of a lecture hall.

Carey showed that this particular MOOC class teaches students the material in ways that are even better than if the students were on campus taking the class in person. In addition, Carey also underscores how the new technology, combined with the discoveries in the fields of neuroscience and education science about learning, can help to individualize the experience of taking MOOCs.

Carey tries to convince his readers that colleges and universities will be falling by the hundreds (or even thousands) in the next several decades.  Some research results seem to support Carey’s prediction. According to a 2010 Sloan Survey of Online Learning says there has been a 21% growth rate in online enrollment, compared to a 2% growth with higher education student population overall. However, Parke Muth points out that Carey has left out at least 5 things that will undercut any relatively fast transformation of the education landscape:

·         Despite what research data shows, many people still believe that on campus experiences make for a much deeper and fuller preparation for what will happen after graduation;
·         The schools will fight off their competitors and will not just wait around while being overtaken by MOOCs;
·         Some course activities are difficult to accomplish online, e.g. conducting labs, and other hands-on activities;
·         In the U.S., testing companies (e.g., Educational Testing Service (ETS)) also have a vested interest in trying to keep things as is and will fight off completion by MOOCs; and
·         Security is still a big challenge as it is still difficult to totally control online cheating.

·         First it should be noted that cheating also occurs in on-campus classes and improved technology will make it more difficult to cheat; and
·         The rate at which online/MOOC classes expand in comparison to on-campus classes can be debated. However, it seems obvious that we cannot deny the fact that online/MOOC classes will become more recognized and play a key role in future U.S. and international education.

·         Check out a free or low cost online/ MOOC course or program that could start the ball rolling for you;
·         For the U.S., the National Center for Education Statistics (NCES) allows students to find/ filter programs based on distance learning options, education fields and geographic location.  To check them out, please click here;

Why you should be checking out free online courses on cloud computing?

What is cloud computing?
·         If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes. Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers. They typically charge for cloud computing services based on usage, similar to how you’re billed for water or electricity at home.
·         Below are a few  things you can do with the cloud:
o   Create new apps and services;
o   Store, backup, and recover data;
o   Host websites and blogs;
o   Stream audio and video;
o   Deliver software on demand;
o   Analyze data for patterns and make predictions.
·         Top benefits of cloud computing include:
o   1) lower cost –  as it is cheaper and more convenient to pay monthly electricity bills than making your own electricity,
o   2) greater speed,
o   3) global scale – system is flexible and can deliver the right amount of computing power needed,
o   4)  high productivity,
o   5) high performance, and 
o   6) reliability – robust data backup.

·         With cloud computing, collaboration between students and teacher can happen from anywhere from any device - tablet, laptop, or phone;
·         Teachers are no longer going home with a bag-full of papers to mark;
·         Via the cloud, and with no need for USB flash drives, students can easily share their essays with their peers and teachers. The peers and teachers may then provide comments so the students may  make the necessary changes;
·         Teachers are more fluent in their curriculum design. E.g., a teacher might see a great example from first period, snap a picture of it and upload it into his/her presentation for  the second period's benefit. 
·         Students can create their own TED Talk and upload it onto the cloud where the teacher can access and assess it;
·         Students who were sick or unable to attend class don’t miss out because they have immediate access to what was done that day. The cloud keeps them up to speed with their classmates;
·         Parents can see grades, check to ensure that all assigned homework has been completed, and nudge their child along if a piece is missing; and
·         Educators outside of urban and private school environments have equal access to world-class, global educational sites and teaching environments.

Joe Mullich, came up with 16 major ways in which the Cloud will change our lives after interviewing numerous experts in the various fields of cloud computing. Nine of them are as follows:

1)      Everyone will become a gamer:
Gaming is called the “killer app” of cloud computing, and the same gaming principles are now being extended to many other areas. E.g., the new generation of wellness and chronic disease management programs use gaming techniques to educate and coach patients in real time.

2)      Repairing objects will be easier:
You can expect to get earlier notification when things around your house or office are about to go on the fritz. E.g., a cloud-based app alerts drivers of electric cars when their batteries will run out of juice.

3)      Computers will become invisible:
You will be able to walk into a room where there may be hundreds of sensors that could respond to your gestures and movements.

4)      You’ll be able to make smarter decisions:
The cloud can turn any mobile device into a “supercomputer” meaning you can access processing power as needed from the cloud to analyze virtually any type of information wherever you are.

5)      Laptop security breaches will decline:
The cloud can eliminate concerns of security breaches by having all data securely stored on the Internet. The laptop no longer stores the data; rather, it simply becomes the instrument by which to access it.

6)      Public/private clouds will make homes healthier:
E.g., the cloud allows doctors to wirelessly monitor patients with sleep apnea, collect information and then tap into a network of experts to devise a treatment plan.

7)      Developing countries will become new markets and new competitors:
Developing countries can embrace the cloud quicker and exploit new opportunities faster, since they won’t be as delayed by tasks like integrating legacy technology.  The cloud will also provide new opportunities in these emerging countries as mobile devices will become the outlet to open up huge new markets.

8)      Everyone will bootstrap:
The cloud offers individuals exciting ways to collaborate, develop products and test ideas rapidly and cheaply, which could accelerate the rising rate of entrepreneurialism. “You see small startups using the cloud to do complex modeling of new product offers,” Hagel says. “The speed at which you can identify what people are interested in, and what they will pay, really changes the nature of innovation.”

9)      Language barriers will fade: 
Today, cloud computing already gives mobile-device users a level of speech recognition accuracy that is virtually on par with call center-based transcription services.  In the future, your mobile device will enable you to communicate with someone who speaks a different language. The words that are exchanged  are instantly translated into each other’s languages using voice recognition and translation software.

·         Major cloud technology companies invest billions of dollars per year in cloud Research and Development. For example, in 2011 Microsoft committed 90 percent of its $9.6 billion R&D budget to its cloud.  Research by investment bank Centaur Partners in late 2015 forecasted that SaaS (cloud computing) revenue would grow from $13.5 billion in 2011 to $32.8 billion in 2016.
·         Cloud computing has come of age.  The business and commercial opportunities are enormous and many companies are already enjoying significant business benefits.

The number and quality of free online cloud computing courses have continued to grow.  You can find some of them via the links below:
