[ J ] a [ Y ]

I've been seeing this girl for about three solid months now (since late January). At one point, she said that I wasn't communicating with her enough (I'd really only call / text her to organize our next get together). As I started getting more attached and everything, I found myself texting her a few times throughout the day - which is I guess what she wanted. Then all of a sudden I'm "smothering her", so I thought I'd back off for a few days and let her make the next move.

In my mind though, I'm not going to be waiting around forever. I was thinking that if I haven't heard anything in the next few days, I should pretty much give up and move on.

What do you think though? How long should I wait?

Hi all. This question has been hovering in my mind for a while now. Lets say I buy a protein bar that has roughly 30g protein, 10g fat and around say 10g carbs including sugar per 100g. This only adds up to 50% of the total mass and I see this trend a lot with nearly every consumable on the market.

What makes up the remaining mass of the product?

Cheers.

1. Money and status

2. Knowing that you're making a difference in people's lives

3. An amazing experience that almost nobody else would have.

I'm trying to decide between a few career options, but wanted to keep my question very high level. So, which would you rather?

Hi every1.

I'm at a bit of a crossroads career-wise at the moment. I've almost finished my undergraduate degree (got one exam left to do then I'm out) and I've already enrolled in another university to do my teaching degree to teach in secondary school. I wanted to teach in secondary school because I thought I'd have more creative control over assignments and such (so I can make them interesting and fun) and because you see your students more, you can build a more intimate relationship with them. At uni, I noticed most people (myself included) just show up for their classes (if even) and then take off.

I guess the only thing that tastes a little sour in that picture is that I'm an academic and the prestige of "High School Teacher" is a lot lower than "University Professor".

If anyone in YA is actually teaching in high school / university at the moment, could you give me any advice?

Cheers.

Hi every1.

I was just curious about how one would commonly offer a hand in doing something or offer help in the Japanese language. I know of "tasukeru" as a verb (to help / to save), but I was looking for more of a noun form...I'm thinking <noun> ga hoshii desu ka?

But then again, if its not the commonly used form of expression, that wouldn't be useful. So yeah, in day-to-day Japanese, how would one usually offer help or assistance to someone else?

Thanks heaps.

Hi every1.

I need a bit of a hand calculating the intersection of two probabilities, even in a probability matrix. Given the matrix below:

....E.....F

A--.1---.03---.13

B--.04--.12--.16

C--.27--.06--.33

D--.31--.07--.38

-----.72--.28--1.0

Calculating something like P(A union E) is just P(A) + P(E) - P(A intersect E). Thats simple, since P(A intersect E) is given in the matrix, but one of the subquestions of this asked me to calculate:

P(A union B). Since I don't know the value of P(A intersect B) in the matrix, how can I calculate this? I know the actual values of P(A) and P(B) and have some trend information about how they intersect with E and F, but I'm not sure what to do with that. I looked at the multiplication rule, but I need the value of P(B | A) in order for that to be of any help. Any tips?

Thanks every1.

Hi every1.

I'm just curious if it was possible to force a fractional number into an integer, and how we might express that. I found out recently that you could force a positive sign on a number like this:

y = square_root( x ^ 2)

Raising x to the power of itself causes a negative by negative multiplication, making it positive. Then the square root of the result is the positive co-efficient of the original value, thus forcing a positive sign.

That comes in handy sometimes, like in the formula for calculating variance or standard deviation.

I was curious now though if there might be a similar way to force a fractional number into an integer. With the equation: y = x; I was wondering what operations I could apply to x so that y would contain an integer variant of x. Eg: x = 1.7 and y = 1 or 2, rounding either way would be ok.

Is this possible using mathematical operations alone?

Hi every1.

I wanted to ask people who are using smartphones atm (Android, iPhone, etc) how often would you download a new app? Would you download more than one a day? If so, how many?

I'm about to release a new game for iPhone at the moment and am wondering how many hits its likely to get.

Thanks ^^

Hi every1.

I wanted to ask, especially for those of you who have solar panels installed on your home, roughly how much energy do you actually get out of those? Is it enough to power your whole house? If not, how much of a saving (in the long term) are you actually looking at by implementing solar panels?

Thanks heaps.

Hey all.

I think this habit started when I was 18ish and started having a couple beers or a few glasses of Gin and Tonic around 8pm to relax before bed. I've since given up the alcohol but every now and then it hits 8pm and I'll kick up on the couch to watch a few sitcoms and I end up through nothing other than habit snacking on mandarines or sakata or something.

Is there a way that I can kind of break this habit? I mean its not something that happens often, maybe once every couple weeks, but because its not really out of hunger but out of habit, I usually feel pretty crap afterwards, when really all I'm trying to do is relax at the end of the day.

Any tips?

Hey guys.

I was just curious, especially for anyone who has ever owned a Mazda RX, how does it compare to other engines in terms of fuel consumption?

I was reading about rotaries (the wankel, in particular, which is used in the RX) and noticed that per cylinder, it isn't as fuel efficient as a standard internal combution engine. But considering that the RX-7 for example is able to achieve 250+ hp with only a 1.3L rotary (which I'm thinking is a single cylinder?), so I mean comparing that to a 2.0L inline 4, provided that the driver isn't revving the thing out (which I guess most do, but especially in a manual you don't have to) wouldnt you actually get better gas mileage?

Or if not, exactly how bad is it? For a 1.3L, I really can't imagine it'd be bad.

Thanks every1.

Hi every1.

I wanted to ask firstly if it was possible to represent a boolean condition using mathematical notation, and if so, how to do it.

For example, lets take the following statement:

f (x) = 2x

Lets say I want to modify this function, so that if x < 10, it returns 2x, otherwise, it returns 3x. This is quite a common and simple thing to do in a system flowchart or algorithm using pseudocode, but I'm not sure how to do it (if it would even be acceptable) using mathematical notation.

Any help would be great.

Thanks heaps.

Hi minna,

I just finished watching Elfen Lied, loved it, and need something else to move onto after a long-ish absence from animes in general. Any ideas?

Thanks ^^

Hi guys. I've noticed that you seem to be hearing lately about a whole bunch of ppl who have made a fair bit of cash making mobile apps. Coming from a development background, I'm thinking about trying to capitalize on this consumer trend myself (having just come out of a dead web development business).

Do you think that there is genuine potential in mobile app markets as a way to create wealth? And do you think that eventually the whole thing will blow over like the dot-com boom?

Thanks guys.

Hey YA.

I'm building an iPhone game at the moment and was just wondering what everyones preferences were. Do you prefer games that have individual stages (stage 1, stage 2, etc) or a game that has more or less one stage that loops infinitely until you die, with the aim being to achieve the highest score, not complete the most stages?

Thanks every1 ^^

Hey every1.

I'm trying to strip body fat atm and am doing about 40 minutes of cardio 5 days a week. Anyways, I used to run a circuit about 6.6km that was about 1/3 uphill, 1/3 downhill and 1/3 flat. I could complete 40 minutes of that no problems.

Recently, I changed tracks to a football field nearby, since I figured a flat plane would actually be easier. As it turns out, I struggle to complete 20 minutes on the flat track. I always thought a flat surface would be easier than an "ups and downs" circuit.

Is a flat track actually harder or am I overlooking something here like maybe hydration, ambient temperature or focus? Oh, and would you say it'd make a major difference in weight loss training anyway (assuming that the gradients we're talking about here are fairly minor).

Thanks ^^.

Hey all.

I just started Judo a couple months ago and, while Judo is definately more than enough to occupy me for the moment, there are Aikido lessons being offered at the same dojo where I train Judo (by a different sensei). A few sempai from my Judo kan took an Aikido class when it opened, but they're pretty pro-Judo so their responses might have been a bit biased.

Anyway, I just wanted to ask anyone whose actually tried both Judo and Aikido exactly how close the syllabuses are for both styles of Jujutsu? I read that Judo was a combination of Kito Ryu and Tenshin Shinyo Ryu, but Kito Ryu was actually derived from Aiki Jutsu (as was Aikido) so I'm curious as to how much of Kito Ryu that had bridged into Judo's syllabus matches up to whats in Aikido.

Thanks heaps everyone.

Hey all. I started driving manual about a week ago and I'm loving it so far. The only thing is, I've been sort of cheating at a set of lights by keeping the clutch just below friction point so I can take off really quick and not tick off the guys behind me. I've since realized that by doing this I'm really eating away at the teeth of my clutch plate. I wanted to ask, which of the below ways to start a manual from a red light entails the least wear and tear on the car?

1. Clutch just below friction point, shift stick in first, footbrake pressed. (current method)

2. Clutch fully pressed, shift stick in first, footbrake pressed.

3. Clutch engaged, shift stick in neutral, footbrake pressed.

4. Clutch engaged, shift stick in neutral, handbrake engaged.

As a side note, what wears out faster, a footbrake or a handbrake? When I think about it, you use your footbrake to decelerate (with downshifting), so using the handbrake at a set of lights to stop the car rolling back shouldn't cause it to wear out faster, right?

I cant quite figure out how an std::string or char* can hold a seemingly infinite number of characters and yet be only 4B in memory. Logically, 4B can only hold 4 characters, since each ASCII character takes 1 byte to store...

Hey all.

We all learn about the digestive system from around grade 4, but even after having done senior biology at high school, we don't really cover exactly how the human body absorbs energy from food. I've read in a few articles that food actually doesn't contain energy. That is, you can't say this bowl of rice has 200 calories in it. Rather, the body generates 200 calories from it. I'm really not sure if thats true, but I'd really like to learn more about the whole process.

Thanks all.
