  • I selected option 4 over option 3 - because most of the data concerning 3 is not big data - rather it is mapping and imagery which are Big Volume Data, but are not Big Data as such mapping and imagery is readily analyzed by GIS and imagery tools.

  • agreed. But causality is not established.

  • Agreed. Correlation is one thing, but causality is another. So much data analytics does not go beyond correlation.

  • A large degree of medical consultation can be handed over to machines. Already a significant percentage of people try to self-diagnose anyway with online resources. I am one of these - and you get good at it too. So especially for more routine consultations I don't see a problem. Many countries don't require prescriptions for many medications and...

  • Good intro course. Well prepared. Just the right length too.

  • @NickGarland we can't

  • Useful glossary.

  • Thanks for sharing the link.

    It's easy to say Trump is dumb - stupid tweets, statements and lies. But he is very deliberate and knows exactly what is saying and doing to appeal to a particular base that got him elected - all on false pretense. This is where US public media got it so wrong for so long. Trump manipulates his base and will continue to do...

  • Useful video. Simple clear messages.


    We see Amazon actually now moving to bricks and mortar.

    " One of Amazon’s reasons for entering into physical stores is that it allows the retailer to show off its wares and entice customers to buy even more into its ecosystem."

  • I am wondering if Gartner, or citing of Gartner, has gone a bit too far in these articles:
    “All aboard the Hype Cycle! What's DataOps? Well, it has no standards or frameworks. Got it?
    Gartner's rollercoaster trundles into exciting world of data management”

  • Actually, a really normal insurance company - they are all dodgy.

  • Also a late starter

  • "Europol has found that Bitcoin $BTC is still the chosen cryptocurrency of the internet underworld.

    The insight comes from Europol’s latest Internet Organised Crime Threat Assessment (IOCTA) report. Among other things, the research claims cybercriminals still favor Bitcoin over other cryptocurrencies – despite its lack of anonymity...

  • Continued:
    Earlier reports that the Pyongyang University of Science and Technology had started offering crypto courses appeared to confirm the country’s intentions to develop its potential in the cryptocurrency space.

  • Very informative "week". Opened my eyes and mind.

  • My 10-year QRISK®2 score was 7.9% against the score of a healthy person with the same age, sex, and ethnicity being 9%.

    What surprised me was the minimal risk reduction of losing weight - a mere 0.3%. Hmmm.

    But trying the QRISK®3 score which includes allowance for 2 standard deviations of systolic, i came down to 7% against the score of a healthy...

  • Good advice from Dr. Hobbs!

  • I definitely agree with the limitations of BMI raised in the video. Many rugby union , rugby league players, especially forwards would have BMIs classed as overweight 25-29.9 or even obese 30+. But they have good powerful shapes.

    Australian Football League (Aussie rules) player turned American football punter Ben Graham 196 cm and 107 kg a BMI of 27.9 -...

  • I used to be so relaxed and never worried about my blood pressure - always 110/75 or thereabouts - since I was 17. Little did I realize that with each stint in Afghanistan, each situation I experienced, how it does get to you and such stressful situations, prolonged do push your BP up. Experiencing conflict younger in life, seemed to be all OK. But as I...

  • @PatriciaFalon I agree that the Fitbit is very useful. I wear mine almost 24/7 and discovered that i have a very low resting pulse - down to around 40 during deep sleep. At points during the day around 50. Fortunately all is Ok and is not uncommon with (some) athletes. So I am a big fan of tools such as fitbit for monitoring heart, exercise etc.

  • Found Jon's video to be very useful.

  • Over the past couple of years I have watched the number of Big Data "Vs" grow from 4 to 5 to 7 to 10. Now I see 42 Big Data "Vs":

    Is this quest for Vs really just Verbomania driven by the Verbile mindsets of Vagarians?

    So I am glad this course has kept it sensible like Gartner did.

  • Glossary is excellent!

  • For general interest - health and well-being. I am looking forward to learning.

  • Looking forward to this course.

  • It may be me, but I found this course more on the hype-side - similar to my business dealings with Fintechs now in several countries. More hype than rigor - so I was disappointed.

    An area not covered is the Russian interest in the technology surrounding virtual currencies. Last year, employees of Russia’s spy agency attended a meeting where international...

  • Thanks @YewandeO . Actually MFA is being increasingly done without human intervention - fully automated. Good examples are digital signature verifications. But I guess it is not perfect.
    Blockchain is not yet perfect either and we all fear the 51% attack. Ethereum seems to have had issues more than others.

    Importantly it would be good to see how...

  • Thanks for sharing. "Oracle - which says the data will be owned by the World Bee Project - will use blockchain to verify that the data is coming from a particular hive and hasn't been tampered with."

    In this case, immutability would seem to be the main objective.
    It would be interesting to know what alternatives were considered - if indeed any. I am...

  • Uber and Airbnb are two examples of companies that took a foothold by avoiding paying the normal taxes and costs that comparable businesses had to pay by law.

    For example, Uber not paying license fees for commercial vehicles and avoiding commercial vehicle insurance - putting the passenger at risk. How good is that?

    Airbnb - not paying hotel taxes and...

  • Correct @JohnHiggins

    It is another set of middlemen - miners.

    How transparent is it - well you don't know the miners anyway - so that is not transparent?

    82% of blockchain mining pools in China. Hmmm

    What has concerned me much about this course is the bent on...

  • Final test has at least one ambiguous Question.
    Q1. We know that in old traditional systems, data is commonly stored in centralized spots. How many servers are to be found on a Decentralized Network?
    I would argue that all answers are incorrect. I disagree with the given answer.
    Decentralized computing networks, are simply networks without a centralized...

  • Thanks @alanbennett
    Just returned to this after a couple of weeks.
    I have the correct answers to both parts, but every time I submit, it always shows "partially correct". Not sure why.

  • Spot on! The example of IP is a good one. In spite of the Berne convention, global IP regulation is very uneven and we have seen countries like China thwart it for decades. China signed on and largely ignored it.

  • Interesting responses. On reflection, it is like solutions looking for problems to solve.

  • "Digital currencies have changed the financial sector forever."
    I strongly disagree with this first statement. The technology is still emerging and that is profoundly portrayed on the very well-respected Gartner hype cycle, 2018, where blockchain and cryptocurrencies are at the stage of Peak of Inflated Expectations. ...

  • Q 4 in the quiz is incorrect. There seems to be a glitch in the showing of the correct answer for the first blank

  • I forgot to add that depth at best is down to about 35 m max - and waters need to be clear rather than turbid.

  • Crowd-sourcing should not be confused with VGI - volunteer geographic information.

  • absolutely correct.

  • What a tough bunch of people!

    Constructive dissatisfaction is more persuasive . In that regard I think @Catherine Dyer has nailed it better than most in her comments. Well done.

    I found the course interesting, informative and useful. Room for improvement - there always is. In particular, video quality was an issue.

    Thanks to the Purdue...

  • well explained!

  • Excellent course - highly educative, outstanding downloads and well presented videos.

  • Excellent demonstration and a very clear explanation.

  • The Obesity video is great. The youtube posting has an interesting set of comments, especially those that seem to be posted by US citizens.

  • The Australian Grim Reaper AIDS prevention TV advertising released in 1987 seemed to have been very effective. Although criticized by some (not all) in the gay community, it nevertheless worked. It was axed after less than 3 months for being too...

  • Worked ok for me.

  • The 5 bullets listed in the Course Summary are excellent.

  • Well prescribed by Dr Collins.

  • I found Tom's messages to be OK, but his written message on his LinkedIn site to be far more compelling.

    But Tom has now moved on to the American Academy of Dermatology.

    But he seems to jump ship too quickly and moves on to other career opportunities.

  • I would suggest that Coca Cola has a 100+ year history of persuasive communications that for the main part has been overwhelming successful, keeping it well ahead of rivals.

    But there has been exceptions when it launched "New Coke" in the mid 1980s and the backlash almost killed it, albeit...

  • After listening to the 15 second clip several times, I am left wondering so what.

  • The transactional communications model is well accepted. It is also sometimes called the circular communications model - the exchange of messages between sender and receiver where each take turns to send or receive messages - but sending and receiving can be simultaneous. Of course, each person reacts differently - based on his/her own culture, education,...

  • Agreed. Interesting book just above Dr Collins' left shoulder:
    Out of Control: The New Biology of Machines, Social Systems, & the Economic World Paperback , Kevin Kelly, 1994. Not a bad read - and not completely out of touch with where things stand today.

    I liked the video too.

  • Geez! There are a lot of tough people here . Anyway I found the video informative.

  • 419 comments to date! There is indeed a lot of interest. My purpose - why not?

  • Hi Morgan - Yes indeed, I was praising the 1 pager under Downloads. The one in the body of the text produces access denial you have reported.

  • How has this changed your thinking? No.

    Do you see the Web in a new way? No.

    Do you think that your activities on the Web will change because of what you have learned? No

    All No, but none of these were expected from me.

    However, the course was a great opportunity, to revisit, reflect and remain relevant. That is valuable, and I thank the...

    True Richard. But what may become the norm is not necessarily good for humanity, health, well-being, peace, stability etc.

  • Actually the internet pre-dates significantly the World Wide Web. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, fault-tolerant communication via computer networks. It was picked up very early by universities for communications. So networking also pre-dates the web.


  • Hi gg
    Boolean search. Sounds eons back, but it is still relevant today.

    Boolean logic may be remembered by those who did 4GL programming back in the 80s. It may sound old, but it still underpins SQL and IBM's Informix.

    SQL is one of the most widely used languages to access, analyze, and manipulate structured data. But as we have seen with Hadoop,...
