People hate making decisions that aren't easy. Apparently I can't stand the awkwardness or tension that lingers for even a second or two when everyone looks around to see who's going to take charge and make the decision or take action.
I want to be that person that does. In the past few days I HAVE been that person (not full of myself I swear). I had to push myself in my mind to do it but I guess there are baby steps if I want it to be something innate, something that's instinctive.
Just some reminders so when I forget:
1. You took charge when someone suggested that we should get captain to check that we were doing the pictures right
2. You took charge...a lot in dealing with some project decisions. That guy might be smart but he really doesn't like making even the slightest difficult decision
3. Language project, you definitely volunteered to be the leader first when that chick asked who wants to be the leader and everyone looked around awkwardly.
Take charge.

4 Ways how NOT to write a textbook
Specifically for sciences, math and engineering:
1. Describe a theorem, have maybe one or two examples and the proof of the theorem.
Why: More examples. Now. At the least 5-7 examples. The more examples the students can look at with step by step explanations the better they'll understand the theorem/topic/whatever. Proofs are almost always space-wasters but can be helpful if it's explained in a less dense form. Please oh please explain them better.
2. Placing at the end of the chapter only problem sets that are many times harder than the ones in the examples.
Why: Ease the student into applying the theorem/topics they learned in the chapter. You don't just throw a kid into deep water after only showing them a video on how to swim. There needs to problems for all topics covered in the chapter spanning ALL difficulties. In fact this is the reason that motivated me to write this post in the first place. It wastes the student's time and it wastes your time when the students come into your office hours wondering whether or not there was a chunk of the chapter(s) that the publisher forgot to include because of the disparity between the depth of the problems and the depth of the material.
3. No solutions in the back
Why: You don't even need to provide an explanation if the answer to the problem doesn't ask for justification. Give. Us. Answers. We need to compare the work we've done to see if we've done it right. Otherwise we'll do the problem, it'll be wrong and we won't have the slightest clue until after the solutions are posted if posted at all. It's not at all about "oh kids these days don't know how hard we used to have it, we used to have to figure things out and work together..blah blah". No. I just want to know if I need to spend more time figuring out this problem or not or if I applied something wrong to a problem. That's it.
4. Obscure illustrations and quotes
Why: Simply irrelevant. If I wanted to read the history behind the guy that made up Eulerian graphs/see what the guy looks like/read a quote he wrote I'd go on wikipedia and look him up. Saves you ink and saves your editor time. This crap doesn't give the student any advantage in learning the material or doing well on your exams. It's just one more picture we can draw a penis or hitler stache on. Seriously, we do that.

Three Dimensional Arrays
How do you access a three dimensional array? It's on my exam tomorrow, I'll try to explain it and in the process maybe I'll understand it better myself.
Say you have initialized a three dimensional array:
int array[x][y][z]
and you want to access:
array[A][B][C]
the offset will therefore = zyA + zB + C. Add that to the array's base address and you will have the address of the element at array[A][B][C]
Similarly for two dimensions
int Array[x][y]
offset = yA + B
I'll try to add illustrations after my exams, but it makes sense when you draw out out the memory array itself.

Makefile macro $@ and $^
$@ refers to the left side of the : and $^ refers to the right side.
The left side represents the object where as the right side represents the object's dependencies.
Took a while to find this actually, found it mid sentence in an explanation of an example make file.
List of macros:

Woes of Microsoft Word and Visio 2010
Visio 2010...Why did I ever download you? Oh because you're new and people like new shiny things. You were also free because of MSDN through my school. Should've gone the old route with your older and more fun loving sibling though..
Can't get your lines in Visio 2010 to point the right way? Draw a line! That is, if you can find the option. You can't.
Right click the ribbon bar -> Customize -> Create a custom group on the right (mine is named "line" -> add the line capability.
Also if you don't want the same header for each page in Word, go to your ribbon, go to the "Page Layout" tab -> breaks -> next page. This should be done on the page before the page you want a different or no header on.
Now click on the header space in the page you want cleansed. The design tab should pop up. Unclick "Link to previous". Now you can clear the header space without clearing the header for the previous page.
Maybe there's an easier way but google failed me. Or I failed google? I don't care I have reports to write and diagrams to make.

Mealworms Drown
So..I've been raising mealworms for a project.
I put carrots in their tub and the majority of them won't touch it, I've also got oat bran in there so they can burrow and stuff. Well I thought they were maybe thirsty since I haven't been giving them water and they haven't been eating the carrots. I read online that some people sprinkle water. So I put a little water in the tub and it hits some worms on the way. The ones that get splashed on squirm like they're having a seizure and eventually stop, not moving at all. I think they died..
Anyway..don't water your mealworms, I guess I over did the "sprinkling".
