Q: MathJax basic tutorial and quick reference

To see how any formulas was written in any question or answer, including this one, right-click on the expression it and choose "Show Math As > TeX Commands". For inline formulas, enclose the formula in $...$. For displayed formulas, use $$...$$. These render differently: $\sum_{i=0}^n i^2 = \...

@Malachi ^^

I found that one. thank you...lol

just parsing it for the symbols and such that I am looking for

not a very well formulated answer, could be better but it has been a while since I have done Geometry

A: Triangles area question

You can assume that the lines are parallel otherwise the shaded area would not be the same area as the un-shaded area. Because those areas are equal we can say that $\overline {AD}$ divides the original triangle in 2 equal halves which means that ΔBAD $\cong ΔCAD$ so $\overline {BD}$ and $\overl...

Math is confusing °_°"

I used to love math

I still have my calc 101 book

I don't remember half the trig to work through it though

That's an awesome error message.

yeah, it's only missing "SNAP" as a caption ;)

that's the .net framework 4.5.2 developer pack -_-

i'd really love being a .net developer if it didn't involve using windows

@mjolka IKR

@mjolka Have you seen SNAP before? It's a trip!

@Phrancis no, what is it?

You sure? You won't be able to un-see it... Right @Mat'sMug? ;-)

now i'm worried

Q: Simplifying A Class Template

I wrote this code over night for a little project that my friend and I have been working on. This Class template was created over a year ago during as a class assignment for C++ programming. I recently reviewed this program and I saw that I created multiple instances of my classes in order to p...

One happy customer:

you just taught me something new and very cool. i had no idea that i could create function calls like that. i still consider myself very new to programming and C was my first choice. i guess you could say i just dove in the deep end of it all (and im still learning and reviewing, gotta get into structures again soon). as i wrote the program, i could tell there were better ways to do what i was attempting to do, i just didn't know how and since i'm teaching myself, i thought some peer review might lift my spirits and give me some good feedback. which so far, i'm very impressed. — jargonjunkie 6 mins ago

Morning

Guys, do we review answers like we do question codes in Code Review?

@Mehrad if you post your answer's code as a question (linking to the original post for context), there's no reason why we couldn't review it :)

has to be your answer though

@Mat'sMug, somebody answered my question. However I really can't understand what is he talking about

no it's not mine

perhaps it's better to invite him to chat

can you create a room?

I just want to know if I am missing out on the point he wants to make (or she. No gender December. you know)

10:39 PM

Answer link?

I should be able to

feel free to comment on their post; if the conversation get lengthy the SE System will create a chat room for you

A: How to achieve less repetitions for applying the same method to multiple properties?

The two variables include: a) Multiple properties b) Multiple operations. For condition (a), having a class will encapsulate everything there itself. For condition (b), you can have a ConverterUtil class with static methods having multiple operations and also one String-related-function that cal...

imo, all he want to tell me is that I can have a separate class to handle operations on my strings...

i guess

@Mat'sMug. interesting. didn't know that.

I'll shoot him some questions

(well you'll have to click on a link to actually create the room - the system merely provides a link at one point)

all good. I can manage that

There are 10 types of people, those that understand binary and those that don't: 01 is pee. 10 is poop. 11 is both. — user3321 2 hours ago

My knowledge on Reflection is very new and I haven't had a chance to use it in my code so I opologise if this question is a total non sense. @Mat'sMug. Do you think I can benefit from reflection to reduce repetitions in the snippet I posted in my question?

Like, getting the properties of my class and applying this sole method on all of those properties contents?

@janos that is a good answer

haven't really looked at your question, but that's what reflection does - getting the properties of my class... (among other things)

I need to get to work though on some website Quoting

@Malachi I have a feeling it's not

probably the whole point is proving without assuming the lines are parallel

10:49 PM

@Mehrad do note however that using reflection incurs a performance penalty - most of the time there's another way out

@janos the perpendicularity is given

or proving that the lines are inevitably parallel

@Malachi I used the wrong word, corrected that comment

@Malachi is the upvote from you?

@janos yes

But using reflection also makes you look 1337 as fuck so it's a tradeoff between performance and e-penis

oh thank you

@JeroenVannevel you should write documentation for msdn

AD Bisects because the shaded and unshaded parts have equal area meaning that both triangles ABD and ACD are congruent triangles

@mjolka twitter.com/Shit_MSDN_Says

I think the asumption that the lines are parallel is 'premature'.

@rolfl yes?

thanks for the RT @janos :)

@mjolka what did I RT?

10:55 PM

"Unsafe code is less secure than safe alternatives."

that your twitter account?

yup

Q: Heuristic Function in C

int heuristic(Maze* maze, int x0, int y0, int x1, int y1) { return abs(x0 - x1) + abs(y0 - y1); } I am searching heuristic function for a maze which includes the altitudes. I found a code with two parameters(x and y). Is there a possibility to have heuristic function which includes ...

@mjolka looks like a fun account (followed ya)

night :)

@rolfl from the Graphic on that Geometry question there are lines connecting the two similar looking shaded and non shaded areas. I would argue that means something.

@jargonjunkie You have some questions about the use of function pointers?

11:15 PM

@Malachi And I would argue, that for a math question, you should not make assumptions ... Not that i know how to solve that, but you can bet that assumptions will bite your derriere.

@rolfl agreed

@JeroenVannevel, just read your opinion on using reflection. c00l

I suppose since I was learning about reflection I was looking for an excuse to use it.

Jeroen Vannevel

That's normal

half of my code is first written with reflection and then refactored to.. no reflection

Good to know. The MSDN reference that I covered so far didn't mention anything about downsides of using it

I use this code snippet which gets any type of list using Generics and Reflection and creates a comma separated string to be used in CSV format. Now I'm thinking of getting rid of it...

11:53 PM

I use reflection for meta stuff, like fetching and instantiating all implementations of ISyntax implementations in a Parser class; that way I can concentrate on implementing ISyntax knowing that my Parser will just automagically pick it up. The non-reflection way would be to have a method that manually instantiates all ISyntax implementations, and hoping none was forgotten.
