##### Other / Using Technology to Pick up Chicks (or the male equivalent)
« on: February 17, 2011, 01:20:01 pm »
How many of y'all have ever used your knowledge of technology and programming as an ice-breaker with a hot girl? Or hot guy, if you're not into girls? It doesn't have to be for romantic reasons, either. I have used my knowledge of technology and programming as a conversation topic numerous times, none of which were romantically driven.
I'm asking mostly out of curiosity, but also because I have been offered a "job" of sorts to tutor a woman old enough to be my grandmother (at least, she claims to be a certain age, which, if true, would make her about as old as my grandmother) how to use a computer for her classes.

##### Math and Science / A "new" way of looking at the formula for the area of a triangle
« on: January 11, 2011, 05:28:06 pm »
So I've always had problems remembering the formula for the area of a triangle. Until last night, when my mom pointed out that a triangle is half of a square, and suddenly it all made sense (she also remarked that she had had the same problem with that formula until someone had pointed that fact out to her).
It's not that we're missing the obvious. The reason is that math teachers don't (usually) explain the formula for the area of a triangle in those terms, and most people's brains are not wired to make the connection on their own, especially at the point in their development when they are first introduced to these formulas (in fact, the way math classes are often structured can even aggravate the problem, as the formula for the area of a square is introduced much earlier than the formula for the area of a triangle).

Quote from: Formula for the area of a Square
L x W = Area, where L is the length of the square and W is the width of the square
Quote from: Formula for the area of a Triangle
1/2 x B x H = Area, where B is the base of the triangle and H is the height of the triangle

For those of you who are more visually inclined:

##### Anime and Manga / Hetalia
« on: January 09, 2011, 04:56:01 pm »
I've not seen any of the anime (my sister has, though), but I've read volumes one and two of the Hetalia: Axis Powers manga.

One of my favorite things about Hetalia is the historical trivia littered throughout the series.

##### Site Feedback and Questions / Random Idea about the Gender Icons
« on: January 08, 2011, 09:50:07 am »
I don't know if this can be done, but can we use different icons for the genders? I mean, the ones we currently have are kinda small and easy to miss...

P.S. I'd absolutely love to make the new gender icons, if it is possible to have custom gender icons.

##### Site Feedback and Questions / Issues with new avatar
« on: January 07, 2011, 02:32:23 pm »

^This is what I'm trying to use as my new avatar (it's a rotating image, if you reload the page, it should show a different picture). Only problem is that it isn't actually showing the image for more than a handful of nanoseconds (if at all).
I used to have a different rotating image avatar, before I switched to the static one I had prior to creating this new one (I'd go back to the old one, but that site closed down a couple weeks ago), and it worked fine.
If I was getting any error messages, I'd be able to figure out the problem on my own, but I'm not getting any error messages at all!

edit: and as you can see, it works fine when used in a post...
edit 2: It worked in another thread on the forums, but it still doesn't seem to work in this thread.
edit 3: And when it does appear in other threads, it is doing that flashing thing again.

##### TI-BASIC / Ready to give up on a program (since I can't just pull my hair out)
« on: December 26, 2010, 10:57:29 pm »
Strings and I have a love-hate affair going on right now, particularly where my program Chemitab 83+ is concerned. I can't get the program to display all 112 elements correctly. It displays Hydrogen fine, though, and at one point today, I got it to display Hydrogen for all 112 elements. The exit option ('0') also works fine too.

Here's a rough concept of what the code looks like (I'd be completely insane to provide the entire code like this, it's almost 1k lines in length):
Code: [Select]
:Lbl A:Input "NUMBER? ",N:If N=0:Goto X:If N=1:Then:"HYDROGEN"->Str1:"H"->Str2:Goto B:If N=2:Then:"HELIUM"->Str1:"HE"->Str2:GotoB...:If N=112:Then:"COPERNICIUM"->Str1:"CN"->Str2:Goto B:Lbl B:ClrHome:Disp Str2:Disp Str1:Pause:Goto A...

##### TI-BASIC / Using asm( inside a program?
« on: December 16, 2010, 11:55:53 am »
I'm trying to create a program that will run a compiled program specified by the user.

Here's what I've tried (and none of them work, I keep getting ERR:Syntax):
Code: ("Version 1 (with prgm not included in Str1)") [Select]
:Input "PRGM?", Str1:asm(prgmStr1
Code: ("Version 2 (with prgm included in Str1)") [Select]
:Input PRGM?", Str1:asm(Str1
Any way of making this work?

##### Other Calculators / What would you do?
« on: December 14, 2010, 10:38:45 am »
What would you do if someone walked up to you and asked you how to program a calc? Would you point them to some tutorials? Would you take it upon yourself to teach them? A most inquistive person (i.e., me) would like to know.

##### Miscellaneous / 100% is Impossible (continued from another topic)
« on: December 12, 2010, 10:56:27 am »
**This discussion is continued from a tangent started somewhere in this thread**

NLP is providing structures and methods that work on 99% of the people. And if one method does not work on person A then changes are very slim a other method wont work either. NLP also wields the power of language. Both verbal and nonverbal language. NLP has some much tricks in it that it has a 100% succes rate because no one is completely immune to NLP (except for the dead xD)
It is impossible to have a 100% success rate--at least, not without someone fudging the data. And until you provide me with quantifiable, unbiased, scientific fact, I am inclined to be very dubious of your claims.

impossible to have a 100% success rate?

- every time i take a breath, i breathe in air. 100% of the time. successfully.
- this soccer season, i successfully played in every single JVA game. that's 100%.
- i didn't miss school the entire first quarter. i was successfully, 100%, in attendance.

clearly, someone is fudging the data on my life, because it is impossible to not miss school for 45 days. you must have at least one absence.
-Your body doesn't release all of the carbon dioxide that it produces.
-Depends on your definition of "successfully played"--was every pass completed? Did you shoot on the goal and make it every time?
-Both physically and mentally? Did you not go to the bathroom during class? Were you ever late to school/a class?
To fudge data, you manipulate it. Depending on the confidence value used, for example, you can manipulate the data. Another way of manipulating data is in how you describe the parameters of what is "success" and what is "failure".

that word impossible is thrown around too much. i don't agree completely with matthias either, but i'm not going to call his theory impossible.
I didn't call his theory impossible. I said that until he provided concrete scientific evidence to back up his claims, I was going to remain dubious of his claims.

##### TI-BASIC / How does this line of code work?
« on: December 11, 2010, 01:35:38 pm »
I was teaching my mom a little bit about using TI-Basic last night while we were waiting for our flu shots, and we ended up trying to reverse engineer one of the programs on my calc--one that I didn't write myself--and we got stuck on this one line:
Code: [Select]
:sum(2(Ans=3)+4(Ans=5
Could someone please explain how this line works for us?

##### Other Calculators / Boredom = "Stupid" Programs
« on: December 10, 2010, 08:50:21 am »
So last night, instead of being a good student and paying attention in my forensics class (the last couple of folks were presenting their projects, so it wasn't like I was actually missing any material), I played around on my calc.
I ended up creating a program that displays "BORED, SO BORED!" over and over until you press CLEAR or ON, as well as making a picture of a tank using the most complex method possible to create straight lines--first I covered the graph screen with horizontal and vertical lines, then I colored in the squares made by the intersections of those lines that I wanted to have colored in using Pt-On, and then I finished up by erasing the extra lines with Pt-Off.
Until I can figure out a program that draws the picture I made for you, you'll just have to imagine what it looks like (I don't have a link cable with which to upload it to a computer--which actually wouldn't matter, now that I think about it, since I'm currently stuck using a computer I can't download anything on due to my computer crashing last Saturday). But I can share the program I made, so here it is, if you want to try it out:
Code: ("prgmFIDGETY") [Select]
:ClrHome:For(A,1,20):Repeat Ans=45:getKey:If Ans:Disp "BORED, SO BORED!":End
Anyone else have programs they've made while bored that they're willing to share? I'll share some of the other programs I've made while bored in the past once others have shared some of theirs (and most of them are actually some what useful, especially when compared to FIDGETY).
