Comment on MITx 6.002x Course Review by gil

Josh,
I am a controls engineer. So, I do not usually analyze circuits on my typical day to day job. I work more with electrical automation and controls, process control, motion, machine design and things like that. That being said, got into this course to re-fresh what I learned in my electronics course some more than 15 years ago. And yes, it is nice to know that what you were taught is not too different than what is taught at MIT.
So far as per what I could see on the class, these techniques presented are really important in circuit analysis and it is definitely something you want to remember in the future. So, if you work in the field of electronics, you will be coming back to what you learned on this class over and over again. It really sets the foundation for everything else in circuit analysis.

Gil,

Thanks for your response. That sounds good to me too. You are right, they would be mad to give the same questions year after year.

I’m curious, you being an EE, and your experience taking this class. I know two EEs, but I’m not one, and when I showed them the book, they said stuff like “Good God, I’d fail that class” and “Learn and understand this stuff, but after school is over, you’ll never see it again”.

I guess it depends which field you are in, but what’s your experience as an EE? Are you taking the class just to see how MIT does things?

Thanks,

Josh

Hello Josh,

I have been using Python with Numpy/Scipy for years now but found Sage really easy to use. Being able to use the Notebook interface on a normal browser windows is also a plus. Sage is very powerful and have quite a bit of plotting capabilities as well.

After going thru the mid-term exam, I wished I would have saved all my past homework notebooks, it would have made the mid-term a whole lot easier…

I think you can and should publish your sage notebooks. Provided that you publish after the homework deadline, you should be ok. I believe it would be helpful to others on the class and on future classes. Future classes should have different problems (what kind of class gives the same problems year after year ?- hope not MIT ) .
After you post, let us know on the MITx forum, I would certainly like to take a look at it. There are people all over the world that probably have not even heard about it…

Gil,

I am an MITx student as well, and I’ve just started to learn SAGE, pretty much for the same reasons you use it.

Paul Lutus has an excellent primer on Sage that I am using to learn it, which is here: http://www.arachnoid.com/sage/index.html

Things seem a little a**-backwards sometimes, but I’ve also never used MATLAB or Mathematica or anything like that. Anyway, I thought maybe it would be helpful to go back and publish my Sage notebooks for past homework problems. How does that strike you? Is that cheating? I mean, the HW is past already but will future classes have the same questions? I have no way of knowing.

The part of me that does want to publish them says that by putting these out there, we can also increase the use of Sage, which is always good.

What do you think? You can email me at the address given if you like. Thanks,

Josh

Sim Con: I have checked your link and I wish I had come across your VBA-Powered Excel sheet at the time of writing this post. It would definitely have made my job easier. Please let me know if you ever plan on incorporating more assets optimization on the spreadsheet. I would like to check it out…

In reference to downloading historical stock prices from Yahoo finance, there’s an easier way to retrieve the data automatically from Yahoo using VBA. It’s not that difficult deciphering the Yahoo finance API, but I have a spreadsheet at http://optimizeyourportfolio.blogspot.com/2011/05/importing-historical-stock-prices-from.html that already has the VBA necessary. Simply type in a ticker symbol, enter in two dates, and Excel will retrieve the data automatically.

Comment on The Social-Media Standard for Project Management by Dr. Edward Wallington

Dr. Edward Wallington — Fri, 19 Nov 2010 17:27:58 +0000

I agree that starting small is essential, to ‘test the water’, gain buy-in, and also to gain experience. Project managers do not have a great handle on social media (generally speaking!), and so little chuncks at a time which deliver benefits at each stage is appropriate — i.e. implement social media like any other project!

There is also organisational politics to counter, i.e. ‘we don’t do it that way here’, and this needs to be handled well, again small steps is essential.
