Install a New Document Class to Bakoma LaTeX

Tuesday, May 29th, 2007 -- By ET
  1. Download the file xxxx.cls, xxxx.sty.
  2. Copy the style and class files to the folder ‘\LOCAL\TeX\LaTeX’ of the BaKoMa TeX installation directory. (normally this would be under C:\BaKoMa.TeX\LOCAL\TeX\LaTeX).
  3. If there are template files, copy the template file ‘xxxx_template.tex’ to the folder ‘\BaKoMa\Template\Dir\User’ of the BaKoMa TeX installation directory (C:\BaKoMa.TeX\BaKoMa\Template\Dir\User).
  4. Copy the file ‘xxxx_template.lcd’ to the folder ‘\BaKoMa\Template\Class’ of the BaKoMa TeX installation directory (C:\BaKoMa.TeX\BaKoMa\Template\Class). This file usually defines the customizable document properties of the template.
  5. Now rebuild the folder structure. Open the CENTAUR Text Editor or BaKoMa TeX Word and choose from the menu ‘Options/Directories’. Select the entry ‘$TEXMFLOCAL’ from the list and click on ‘(Re)Build ls-R’. Close this window.
  6. The template is now successfully installed. To apply this template for a document, you have to create a new document in BaKoMa TeX Word and choose the template from the list ‘User/xxxx_template’. After clicking on ‘open’ you can customize the specific document options you prefer for your document.

ISMT101 Final Score

Monday, May 28th, 2007 -- By ET

I have finished grading my first course: ISMT 101. This course is called “Introduction to Information Systems and E-Commerce”, offered to all first year undergraduate students in the business school. It was a very intensive semester for me, as it is the first time to teach, not to mention the size of the two sections of 240 students.

I think the semester went well. I proved that I am a great professor. Student not only liked my classes, they also respected me for broadening their horizon. I wish this course could be offered to second year students, that way, I can probably teach more quantitative materials to them.

Just to see how my students did, I plotted some figures below:

The following one is a scatter plot of mid-term score versus final score, they obviously have a positive relationship, especially in the range of high scores. What I learn here is that good students tend to be good students consistently.

The next figure gives the distribution pie chart of the scores, I have roughly 20% A’s, 40% B’s, 35% C’s, then roughly 3.5% D’s, there are 2 F’s, they got the lowest score in midterm and final exam, and missed all my classes, and the labs.

I rank order the scores and plot a nice cumulative figure below:

Finally, I have the histogram to show the score distribution. The curve is nice, as anyone with score above the mean gets at least B-.

The top 5 percentile people get A+. People within one standard deviation below mean get from C+ to C, and people within one standard deviation above mean get from B- to A-.

Overheard

Monday, May 21st, 2007 -- By ET

Your time is limited, so dont waste it living someone elses life. Dont be trapped by dogma – which is living with the results of other peoples thinking. Dont let the noise of others opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

Were here to put a dent in the universe. Otherwise why else even be here?

Innovation distinguishes between a leader and a follower.

Be a yardstick of quality. Some people arent used to an environment where excellence is expected.

The only way to do great work is to love what you do. If you havent found it yet, keep looking. Dont settle. As with all matters of the heart, youll know when you find it.

You know, we dont grow most of the food we eat. We wear clothes other people make. We speak a language that other people developed. We use a mathematics that other people evolved I mean, were constantly taking things. Its a wonderful, ecstatic feeling to create something that puts it back in the pool of human experience and knowledge.

Theres a phrase in Buddhism, Beginners mind. Its wonderful to have a beginners mind.

We think basically you watch television to turn your brain off, and you work on your computer when you want to turn your brain on.

Im the only person I know thats lost a quarter of a billion dollars in one year. Its very character-building.

I would trade all of my technology for an afternoon with Socrates.

How a good photo was taken

Thursday, May 17th, 2007 -- By ET

Found this here.

“No makeup artists, no stylists, no trendy fashions, no managers, no publicists, no record label politics, no artificial lighting, no gimmicks, no self-conciousness. Just natural light, some foliage, and Bjork.”

bjork.jpg

Bjork (1991, Woodstock) – I’m often asked if I have a favorite photo and I can say without hesitation that it’s this one right here. All of the elements combined to make it one of my favorite moments as a photographer, and it happened purely by chance. I met Bjork the night before when she invited herself along and joined some friends and me for a late night pool game up in Woodstock. At the time she was upstate recording with the Sugarcubes. I was already a fan, and had always wanted to photograph her, and when I asked her if I could she said sure. Just like that. We’d been talking all night, she trusted me, and I guess that was all she needed to go on.

The next day I picked her up and brought her to my friend Ben’s house, who helped out as my assistant for the shoot. I knew he had a lovely forest glade behind his house and I thought the setting fit in nicely with her freespiritedness. As happens often in shoots I’ve done (don’t ask me why), she gradually began to to shed her clothes. I picked out a couple of oversized leaves (a la Eve in the Garden of Eden) and she stepped onto a large boulder. At that moment it started to drizzle, she stood on tippy-toe and opened her mouth to catch a raindrop on her tongue. Click.

Having spent a long time talking with her the night before I felt this image really captured her essence - a woodland sprite, a free spirit, playful, earthy, and open . (Some other reasons why this is a favorite? No makeup artists, no stylists, no trendy fashions, no managers, no publicists, no record label politics, no artificial lighting, no gimmicks, no self-conciousness. Just natural light, some foliage, and Bjork.).
