K's Learning Diary

I love it when somebody can just explain a subject to me in simple English and in less than 20 minutes. A nice video overview of Hadoop, very well done!

Quite a cool App.  I have to say SAMSUNG is really doing a good PR job.

I am temporarily rendered speechless by the ingenuity of this device... with sore eyes of course. People have wild imaginations! Before you go off and attach your eyes to the electric sockets, have a look at another video here:

Here is something to think about. How many of you think that we are ultimately responsible for our own actions, regardless of how we are influenced by others or our environment, because we are the ones that ultimately made the decision to perform the act? What percentage of our law-abiding general public do you think, on average, could be persuaded to deliver a lethal, life-threatening electric shock to an innocent stranger? 1%, 5%? Welcome to Milgram's obedience experiment. Shockingly, more than 60% of those that took part were persuaded to deliver electric shocks of increasing strength to a screaming stranger (in the name of a memory test), and even go as far as delivering the final fatal voltage, in which case the screaming subject went silent. The screaming subject is fake, of course, but those that took part did not know this until the very end. Now, are those supposedly "murderers" guilty for their crimes? It is a shocking revelation into the "weakness" of

Quoting the following information from http://www.argondesign.com Single Core Processors were originally developed with only one core, executing one thread at a time. Programmers regularly employ " multithreading " to allow the processor to switch between threads giving the impression that the threads are running concurrently, although the tasks can only be processed one at a time. The only way to improve processing throughput is to run the core faster which requires more energy. Image Reference: tomshardware.com MultiCore A multicore processor is typically made up of two, four, six or eight independent processor cores in the same silicon connected through an on-chip bus , a central intersection through which all information must flow between processor cores or between cores and memory and I/O. Multicore processors do execute threads concurrently, typically boost performance in compute intensive processes and will use less power than coupling mult

Is "feedback" countable or not? Feedback, feedbacks, a feedback? See here: http://www.englishforums.com/English/PluralForFeedback/vlrx/post.htm I like this answer: "The word feedback has evolved over the years, and is now accepted as a countable noun. Therefore, if feedback shared frequently in certain professions, each feedback unit is countable and hence its plural is now accepted as "feedbacks" . Also, when you use the word feedback in the phrase "one of" as in one of the feedback shared with her, sounds rather incorrect. Hence, in modern times, feedbacks is "ACCEPTABLE"."

Okay, so this really doesn't count as a new skill that I have learned, more like an old skill of which I have lost, or forgotten long ago. It has been a while since I have opened up any chemistry books. After A-Level (high school ), Chemistry was never used again due to my career choice, and I have simply forgotten it all. What a shame! because I remember it took a lot of effort and I was quite good at it (and also the fact that my peers that have continued in chemistry are now making tonnes of money - but who is counting). Another thing I have discovered, and I wonder how many of you feel the same way. Although I don't think I have changed or really learned that much in my undergraduate university days, as I got older, learning seemed to get easier as if I had a good IQ boost. I suppose it has got easier partly because we gradually learn to identify important information quickly with experience, and are more able to sort information (knowing how we learn best) in our
