    • Multithreaded programming.



    • Comments on bimonthly newsletter
      • The format should be similar to the ACM Tech News format.
      • The header should contain a title, your name, the class (CSC352) and the date
      • Each paragraph should have a header with a title, the source of news, the date, and possibly a link to the full article.
      • The paragraph describing a news item should be between 3 to 10 lines, give or take.

Week 3
9/17

All the data structures of interest (concurrent non-blocking and blocking) can be found in the Oracle documentation. The information is a bit cryptic, but you need to get comfortable with it!

Week 4
9/24
  • Tuesday: Guest Lecture/Informal discussion with by Tim Draper
    • Some questions to start the conversation:
    • How has the cloud infrastructure changed entrepreneurship, if at all?
    • There is a whole ecosystem growing around the cloud services offered by Amazon and the other players: new companies offering services and using Amazon's AWS for example. What are some of the most interesting companies/ideas/technologies emerging that you have discovered or been involved with?
    • There is tremendous worries about the safety and privacy of data in the cloud. Is this an area of growth students should consider?
    • What other area of growth do you see that students should keep in their view-sight?
    • If a graduating major is interested in joining a start-up company, what are the signs she should be looking for before joining such a group?
    • Some students are interested in a management track, starting at a big company and climbing fast. What is your advice for best preparing for this type of career?
    • What is the most exciting development in your eyes happening now with cloud technology?
    • It has been said that the 21st century is the century of the entrepreneur. Do you see this as true?
    • Companies rise and fall. Microsoft was once the place where all our majors wanted to go. The most prestigious company for programmers. Now it's Google, and Facebook. Which company(ies) do you see as potential new meccas for programmers?
    • If somebody were to form a start-up with friends. Say 10 people. Who/What/Where? Who should the people be? What field should they be experts in? Where should the company locate?



TimMelissaDraper.png


    • Review of Homework 1 and its Solution.
      • Understand static variables
      • don't use global random generators!
      • /usr/bin/time multiplies time by the # of cores for threaded applications
      • be sure to understand if you need the same random seed or a different seed in your experiments
      • create a different user on your laptop with no extra applications loaded in the background (e.g. Skype): less stress on the O.S.



  • Thursday Mountain Day!

        • Are the contributions of paper clear? The section on related research sufficient?
        • What is being compared? Similar machines? Hardware? Software?
        • Are authors partial? Do they have a stake?
        • How does the paper advance the state of research?
        • What does it tell us about the way computer systems evolve?
    • Thinking about the project
      • What do we know better about the overall project. What pieces have we looked at?
      • What is it we don't know?
      • Can we turn any of these questions into a project?



Yahoo has some very good reading material on Hadoop. One reason is that they may be one of the largest users of AWS and of Hadoop.

Week 12
11/19
  • Tuesday:
    • 1 month to go (exactly) before the project is due (Dec. 19)!
    • Student-directed work (DT @ INFOCOMP 2013)
    • Finish the MapReduce lab on AWS and make sure you do the Challenge 2 part of the lab.
    • Food for thought: some videos
      I suggest one of you connects her laptop to the projection system and you all watch these videos together. After each one, discuss it as a group. Take notes and be ready to share your comments during Thursday's class when we resume our regular schedule.
      • The Cave 2 Project at the University of Illinois: Just another hardware solution for presenting the user with a large number of pixels; in this case 27320 x 3072 pixels. Short, 3 minutes.


      • The Creators Projects video
This video is not necessarily anything that can work for us, but it's just "food for thought." Just a different way an artist has come up to make still pictures interesting to look at. Short, 6 minutes.


      • O'Reilly Radar Videos
OReillyPerlBookCover.jpg
Tim O'Reilly is a visionary who figured out a long time ago that computer technology was an exploding field and he started a very successful line of books to support all new technology projects that were emerging and promising. The books all have animals on them and are uniquely easy to spot. O'Reilly now also has an on-line channel (O'Reilly Radar), and organizes conferences with top researchers and intellectuals in the field of computer science.
The first video is with Doug Cutting, one of the creators of Hadoop. He makes some very good points about what Hadoop is, what it is good at, and what it might not be good at (Homework 5 lesson?). After Cutting you can skip the 2nd interview (about video technology) and zip to the 3rd interview with Jeremy Howard, at time-tag 13:47. Then learn about big data and analytics, and what is said of data scientists. About 12 minutes total.


Good interview of Tim O'Reilly describing Web 2.0, and his view of a data-driven Internet. 8-minute long. You may want to think about how our wikipedia data (images, stats) relate to what is said about data as described in the interview. About 8 minutes.


The next video filmed in June 2013 presents Bruno Fernandez-Ruiz of Yahoo, who speaks about Hadoop since 2005, Hadoop today, and what is ahead. An important type of data property Fernandez-Ruiz is interested in is timeliness, which we haven't really looked at for our project, but you will see that it could apply easily to the dynamics of wikipedia. Some interesting statistics about the number of servers, the size of the HDFS they use, the number of processes are given. About 17 minutes.

    • If you have at least 25 minutes left before the class time is over, do the MapReduce-Python lab, without attempting the challenges at the end. We'll do these together.
