this is halloween



This is beyond awesome =D.

Sad how stranger danger doesn't exist in a country where it is a constitutional right to own firearms =P

Posts will be irregular now because I hardly even turn on the computer. Please be crey.


And I'll take it as a "no, nobody wants cases" ='(
Forever alone.

powerful phone protector plus pet peeves

So I found an awesome case for iPhone 4 and iPhone 4S. Ordering from the US, and I might as well get more if anyone wants it, because I don't think they sell it Australia. Saves you from ordering one yourself, as well as only 1 charge for shipping for multiple items (Y). So if you're interested, tell me here, MSN, email, text, I don't care =D

Without further ado, I present the Lifeproof case:
It's shockproof [(Military Specifications MIL-STD-810F-516.5 (2 meters/6.6ft drop on all surfaces and edges. 26 tests) - if that means something to you]
It's waterproof and dustproof (full IP-68 rating against water and dust, and designed to Military Specifications.) Dunno what that is, but it means 2m submersion is safe.
It's also snowproof and I'm sure we'll be needing a lot of that soon. /sarcasm

And here are pictures of the black and white cases (there are pink and purples as well)



If you wanna see it on the original site, you can see it on Lifeproof.com. It lists all its features and etc.

It's much slimmer and elegant-er than you'd expect from something that protects your phone from all that shit. But now you'll probably doubt it's protectiveness, so check the next two videos if you're in that zone.

Here's a video released by Lifeproof. It shows a shitload of abuse, way beyond what normal people do. But it covers dropping the case while it's on your lap and you're exiting the car. Or you just drop it by accident:


Here's one at the beach demonstrating mainly waterproof-ness



Now, the price. It is advertised at $80, but plus p&h will be anywhere up to $95. Obviously, the more people who want one, the closer it approaches $80 xP. This is pretty steep, but if you go sportsing with your phone, hiking with your phone, beaching with your phone, or drop your phone/scared of dropping your phone, then it might be worth it, seeing as your iPhone 4 costs upwards of $800.

Now since I caveat emptor'd the shit out of this, and so should pass on to you, here are pros and cons.

Pros (I gathered these from review vids):
Well it IS kinda waterproof, shockproof, dustproof, snowproof. Unless you're being a massive idiot and pegging it around, your iPhone is freaking safe.
You can take it anywhere! ANYWHERE!
All buttons are accessible, chargeport can be accessed by flipping the bottom catch open (obviously this will de-waterproof it while it's undone but you shouldn't be getting it while wet while charging anyway)
The material on the outer casing doesn't grab lint at all.
It's so thin and sexy!
It uses something that makes the whole case resonate, so that sound from speakers can travel through the waterproof case. Speaker and microphone quality shouldn't be affected - they will replace it if it's terrible.
Apparently the home button feels even nicer to press.
Separated optical lens for flash and camera - no chance of flashback, and hax clarity.

If I haven't mentioned it as a con, you can imagine that it's a pro :L

Cons:
Screen protector is glossy and takes getting used to. It's not adhesive, so it may need to be "broken in" to sit nicely against the screen.
The volume and lock button are not as crisp, but still easily accessible since the case is so thin.
It's not designed to be taken on and off frequently. Unless you're cleaning the interior or repairing, it basically should never come off.
(Minor)Silent/ringer switch is reversed, ie pull to the right for silent, pull to the left to ringer.
The chargeport basically only fits the original Apple iPhone cable.
Pretty freaking expensive
Only for iPhone 4 and 4S


If there's an issue I haven't mentioned, please talk to me =D
Ordering on Nov 1 btw. So tell me before then (Y)






PEW for PET PEEVE
I hate question marks that shouldn't be there. Like when people tell you shit? And it's meant to be a full stop but they do this instead?
Because people designed full stops for a reason - for sentences that aren't fucking questions.
Question mark is for real questions. If you want to tell me something, I should be the one asking questions if any.
I mean, if you're asking "Do you remember how to calculate molar mass?", then it is a freaking question. You can use a question mark, because it doesn't make sense with a full stop. This is totally awesome because you understand basic grammar.
"Do it like you did for sodium hydroxide?" is not a freaking question. It is an imperative, changed to annoying form via the use of incorrect punctuation. This is not totally awesome because you need to go back to year 1 to learn what a question mark is for.
Question mark is called question because you are asking a question. Seems obvious but apparently is not. When in doubt, just don't put punctuation. This usually happens on IM or text, and hence people don't care about punctuation anyway.

WHY ARE YOU ASKING ME A QUESTION.
The justification I hear is: "That's how I'd say it in real life?"
My answer: "It's fucking annoying in real life too."

How often have you heard (primary school) teachers say "Don't answer a question with a question" or "Am I asking the question, or are you?", or just "Are you sure?", until you stop using a bloody question inflection.

Thank you and good night

YAY no more Ag. Enough said.

Chilled with some Ag kids at Carlo Court and were loud and probably disrupted a few people's meal times.

Feels good to have a free morning on Tuesday, and of course, 5 more free study periods a fortnight.


Now some largely unrelated musings about living organisms.

Cells divide without really knowing why they're dividing. They think they're living their own lives and dividing for themselves - but they help us function as a whole organism.

What if life on Earth is really just a huge pseudo-organism? Different species are analogous to different cell types.

Because, do you know why you reproduce? Apart from "to have sex". Which is a major part of it, but why?. Life could have just programmed us to really want to reproduce, with no real reason at all, but the reason is just to keep life on Earth alive.

So just like we drive our minions (our cells) to keep us alive, so does Nature drives minions (us! =O) to keep itself alive.

Why am I even talking I should be sleeping lolol

seedy cp on pc cd.

Before I begin the anecdote, I'll explain the titular pun that I thought of a while ago.
Seedy = ... Obvious ain't it.
CP = It's better if you don't understand. Go ask a guy who would know about this kind of stuff.
PC = Personal Computer
CD = Compact Disc

ANECDOTE!

So we had a massive chain of puns at a Cadet power meeting.

So Kerry (Xue) was spinning his phone on the table, and touching the screen so it leaves circular marks on the screen.

Kerry: "Looks kinda like a CD"
Jeff: "Yeah but it's pretty seedy cos it's all like finger grease and shit"
*facepalms all around*
Brian: "Hey look, it's your CDR*!"
Jeff: "Yeah, the CDR is even seedier**"
Kerry: "My circles aren't really good though. You might need a bit of OCD to get them perfect."

[Shits and giggles]

*CDR is a Cadet Development Report
**It was! It was all stepped on and muddy and shit =(


A picture that I took of our hard work. There are 2 school laptops, 1 home laptop, an iPad, and I was referencing my iPod Touch as well. We used all of them.

If I recall correctly:
Main Laptop - The one used to enter the information into the Rolls and the Training Program
School Laptop (left) - A list of activities that we intend to do but we did not place into the Training Program
School Laptop (right) - Opened to last year's Term 4 Training Program so we have a template to work off
iPad - Training Objectives so we can devise new activities
iPod Touch - Whatever random extra stuff we needed

Training Plan - A list of activities and their timings that we (Brian, Johnny, Kerry and I) write, and intend to train our cadets with for the upcoming term
Training Objectives - A list of things that Australian Army Cadets wrote that they want the cadets in Australia to know about.

When we realised how awesome it was that we had all this crap open and we were actually using it, we knew we had to take a photo (Y).

A high 5 to Brian, Johnny and Kerry for being awesome =D

word neutering

It's amazing how douchebag the general population is. This particular aspect is an everlasting tradition that has been passed down from generation. Take the number of medical terms used to mean "intellectual disability" in the past. Then consider how they have been turned into "you're stupid" slurs. Then consider how overused those slurs were that it became "uncool" to use that word.

Btw all smart-sounding historical facts I quote are from Wiki unless linked otherwise.

This is has a much lower potential to be upsetting as the last one. If you were fine with the last post, you'll be great with this post, and I welcome you. If you were not, you're entering at your own risk.

Don't pretend that this post exists in full somewhere other than after you click "Read More". It doesn't exist in my blog homepage, it doesn't exist in Google Reader, it doesn't exist on your Dashboard cos I changed the feed settings.
In the case of technological fuck-up, you can still turn away because I've waffled on for 2 paragraphs (and 1 to come) that you have the opportunity to leave. (And then tell me how you found the whole post so I can fix that.)

So a break here where you can rethink your life choices and decide if you want to quit while you're ahead (and go somewhere else), or continue and agree not to complain (complain =/= discuss btw. Discuss is fine.) later if you regret your choice.

So yesterday, Period 6, I had my first free ever.

It was a day of smooth sailing.

I sauntered into Ext English, dropped off my orange slip, walked out with a spring in my step, getting as far away from Navigating the Global as my lanky legs can take me.

I leave behind memories of Street Fighter IV over Bluetooth, analysis of Daffodils by writing a poem, Monica's epic Paint-rendered pictures, Tilt to Live over Bluetooth, playing Infinity Blade back to back, and generally having nfi what we're doing until a couple of weeks before the big exam.

But I made sure I broke my free period hymen in the correct way.

I was with Tree at the end of lunch (he came from the same 3U class as I did).

First, we had to rub it in to Brian that he didn't manage to get this free because his teacher was not present. It was like
"HEY BRIAN, LETS GO LETS GO PLAY!"
"Dude I have Bio. I haven't dropped it yet."
"Ohhhh NOOOOOO. How come I didn't know that? Shiiiit that's too bad Brian. That's too bad. Sucks to be you"
"You guys are fags"
*victory dance*

Nextly we found Max in the library and flamed him for doing work. Promptly borrowed Carcasonne and subsequently became the most obnoxious table in the library. We were seated in the dead centre of the desks in the middle, so we could distract a maximum amount of people. No like, literally we were like "LETS GO IN THE MIDDLE SO WE CAN ANNOY EVERYONE". That being said, people started watching us and were like MEH SCREW WORK.

We played herped and derped in Carcasonne. I ended up losing quite badly :L but I had fun fucking up castles and stuff and kinda forgot to make my own shit. And then Tree and Max got their miracle piece and I got destroyed. Creds to you if you understand what the hell I mean.

But credits where it's due, it wasn't the same without you Brian. Your scheming and stupid comments add a new retardimension that we 3 alone could not muster.

We still had fun, though, and you should be sour that you missed out.

But yeah looking at the amount of maths I have atm, I think I might actually use my next few frees to like... do ... work. That thing.


PS Just extra stuff that isn't worth its own post:

got your back, jack. bitches be crazy

3 parts for you today. All based on the quote "Got your back, Jack. Bitches be CRAZY!". Brownie points for recognising xP.

Table of Contents
Part 1 - Saj being awesome
Part 2 - My attempt at being awesome
Part 3 - The controversial part that people might get pissed off at but read anyway, just so they can get pissed off and express their views.


Part 1


Saj (disgusted tone): And those chicks, I swear they all either wear short shorts or yoga pants
Jeff: What's so bad about yoga pants?
Saj: They're pretty bad when you can tell they obviously do not do yoga
Jeff: *respect*

Part 2


I was trying to be witty on Formspring when I answered a question:
What inspires you and why?
And I answered that,
Girls at their best and worst inspire lots of stuff.
The piddly amount of songs not about girls is a tribute to this.

Wow guys think about girls a lot.

All the bloody songs are like really positive like "my girl's the best oooh yeah never wanna let her go, I want this to never end, just like a mobius strip woooo. She should strip like a mobius strip because she's also very hot. Let's have sex now!" or some angry emo shit like "fuck you bitch, it hurts so bad, like a sharp stick stuck into my foot, and then I stacked it and the sharp stick also stabbed into my chest. It hurts so bad in my heart."

Anyways this is the first time since forever that I've actually had no-one on my mind. It's been such a long time. You know how it's "don't miss the water till the well runs dry", but like the other way. It's like "never realised how thirsty you are until you reach a well". And even then it's not correct. It's not like it's not fun being involved or trying to get involved with someone. It's just different.

So the correct saying would be "Didn't realise how good Sprite tastes after you've been drinking lots of Coke." And vice versa when you switch back again.

differentiation

I hear lots of people using the word "derive" to mean "take the derivative of" or "differentiate". I personally don't like this term.

While I cannot definitively say that the usage of "derive" to mean "differentiate" is incorrect, I can definitely say I have never seen a textbook or a teacher use "derive" to mean "dy/dx".

I feel the need to differentiate (haw haw) between the two, and explain the usage of the two in mathematics.

Differentiate
This means to take the derivative of. This means dy/dx. This means "kick the power down, subtract one from the power".

Derive
This means "prove" or "find". This means if "a + b = c", then we can derive that "a = c - b". If a question says "derive this function", it will always mean "look at the diagram and the information given, and use LHS = RHS to prove that the function given is correct". It will never mean "differentiate this function".

moral dilemma

I asked on Formspring the question of how these rank in importance: a person's intention, their method of achieving that intention, and the end result of everything they've done.

I have issues with every choice, which I will propose to you right now.

Before I do so, I should define each
Intention - This is what the person wants. It is an idea, and it is not represented by any physical means. A "good" intention is one that agrees with current social paradigms; a "bad" intention does not.
Method - This is they physical form of one's intentions. A "good" method is one that successfully and efficiently carries out one's intention. A "bad" method is one that either doesn't achieve the intention, or is just a morally incorrect way of achieving one's intention (eg intention to own a car - steal a car is a morally incorrect method)
Result - The final snapshot of the situation after all's been done and said. It ignores what has been done during the Method if the Result does satisfy the Intention.

follow the leader

While we're on AFX stories...

On AFX I had a tacit disagreement with the adult officers about my role as a Cadet Under Officer.

I was a Syndicate Coordinator. Don't worry about what it means, except that it's just not the top job within our Course of 93 cadets, and I was responsible for 29 cadets (Y).

I led the way I liked, and they wanted me to conform to the CUO they liked. So you can see what went wrong there.

The way I interpreted my role was that I would plan stuff, find out what needs to be done, find ways to lift morale, and then pass it down to a Sergeant to actually get down and dirty with the cadets.

The way they interpreted my role was to go around and shout at the cadets myself, and give direct orders to the cadets. Now I didn't believe this was correct, and hence didn't engage in this properly, and ended up ostracising myself from the adult officers and instead developing better relations with my cadets (the other CUOs who conformed to the adult officer's views obviously ended up doing the exact opposite).

Now I'd like to mention that CUO Gao (Brian) led in the way that I intended to (that is, not much shouting at the troops. Instead, officers should be planning stuff and finding out things to fix, then passing it down to someone else to shout about). He ended up winning the Best Coy award (a Coy is a Company, a group of 60-80 cadets). He is a smug douchebag and you should punch him when you next see him kkthnx ;)

Here is the time to point out that, in Cadets at least, there is no such thing as a single good leader. There is only such thing as a good command team. There needs to be some magical chemistry from CUO to Warrant Officers to Sergeants to Corporal to the Cadets. If any of those links have bad chemistry in between them, then it all falls apart and no matter how epic the CUO is, it'll be difficult to run it spectacularly.

Even though Brian is smug forever that his Charlie Company won Best Coy award (don't forget to punch him), he knows that he couldn't have done it if his CSM and SGTs weren't also capable (except for a certain SGT who we won't mention here xP)

In that respect, being a "good leader" means firstly knowing how to make good decisions, knowing your role, then being able to connect with many types of other leaders (inferior or superior). There exists not a universally good leader, but only a leader that has the potential to lead well under as many circumstances as possible.Even the "best" leaders will find someone who they don't get along with, and things won't run as smoothly as desired.

Nextly, semi-relatedly, there's what I call "immediate" leadership and then there's "sustainable" leadership. In my mind, "immediate" leadership is the intimidating, rawrblargh in your face type, where shit gets done, and it getes done quickly, at the compromise of the happiness of your inferiors. It is effective in the short term, but it sacrifices morale, and in the end your troops will end up tired of your shit.
"Sustainable" leadership takes a while to get started, but it develops better rapport with the inferiors. In the beginning, the inferiors might think you soft and may not obey you. Also, without being rawblargh in your face, sometimes the message gets lost. But once it gets going, your inferiors will respect you (assuming that your actions and decisions to date have been good ones), and shit will get done with minimal input.

As Inception kindly pointed out, "positive emotion trumps negative emotion every time."

Here's my model atm for my interpretation of effectiveness:
- Don't say anything unless you are sure of what you want. When giving directions they should be clear cut and be completely unambiguous. Umm's and ahh's also make the inferiors doubt the solidness of your decisions, and hence get done with less conviction.
- Never let your inferiors know that you are flaming them because someone else flamed yourself first. Let's say it was because of rubbish. The CUO would wtf at the Warrant Officer, and the Warrant Officer will wtf at the Sergeant. Now the Warrant Officer should flame the Sergeant because letting cadets leave rubbish around is wrong (not because the CUO flamed the Warrant Officer).
- Don't deny comforts unless there is a good reason to, and you can justify to your inferiors. If cadets are cold and they ask "Can I putz on a jumperz lol?", it's bad for morale if you say "no." You instead say "Don't put on a jumper unless you don't think you're going to survive. The sun's not down yet and it's yet to get colder."
- It's okay if there is a gap in your own knowledge. You just have to know how to find out. For instance, all I knew about asthma was that people can't breathe and they should puff from their reliever. I had the fortune of having a cadet say "Sir, I can't breathe." I knew very little about asthma, but I made sure she was holding her reliever while I sat her down. Note that this was during the abseiling activity, where no adult officers were present yet, and the St John's standby team was yet to arrive. If there are any cadets here, want to take a guess as to how I obtained the knowledge of how I knew how to deal with this attack?
- There needs to be a balance between being close enough with your inferiors so that they can trust you, yet be distant enough that you can give them orders.

Now I asked on Formspring for people to rate in order of importance - Results, Intention, Method. Here again I come back to this to evaluate a situation. I believe that the officers rated my performance valuing method over results and intention. I also noticed on Formspring that almost nobody (only 2 out of 33 people) chose Method as the most important result. My personal view on the rank of importance is [lol jokes you can find out in the next post when I go into this in detail].

In the eyes of the adult officers, my Method was shithole, my Intention was assumed to be good, but it was undeniable that the Results were better than they expected.
The Cook-Off wasn't due to any input from leadership, but the mini Chief of Army Challenge was! Each platoon (~30 cadets) was split up into sections of 9-10 cadets. They went around to various activities as a "test of objectives" to confirm that the week's training was successful and they remember how to do their shit. Out of the 12 sections that participated, first place and third place went to sections in my platoon (3PLT cheer! Lol jokes nobody from 3PLT is reading this).
Due to the nature of leadership that I stated before, it's impossible to claim my cadets victories throughout the week in my name alone - I could only make sure my Corporals were happy enough to keep the cadets happy motivated enough to learn and participate. As cheesy as it sounds, it was a team effort.

Anyways, storytelling aside - what do you think is the most important and least important out of Results, Intention and Method? Remember your answer because my next post will be quite the epic if I do say so myself.

drawingz

I bought a viewee tooee (a notebook thing of sorts) for Cadets, and now I want to draw something on the front of it so I can tell which side is the front.

I have a few ideas in mind (I'm going to Sharpie the picture on)

AAC Crest

Rising Sun

Australian Coat of Arms

Stylised Coat of Arms
James Ruse Crest

JRAHSACU Hat Badge

In the end I settled with the AAC crest and ended up with something that looks like this



Needless to say I am quite proud. The text is a little bit wonky cos it's so hard to write along a curve, and also my right hand had nothing to rest on and was kinda hanging off the edge. Nonetheless it is still readable even though the pen really wasn't fine enough.

Don't worry, I didn't copy this freehand, I traced it using an ingenius method (yeah, fuck modesty). Ordinary lead pencil doesn't draw well on the cover and pressing down with a pen doesn't indent it visibly. But I persevered and succeeded 8D. I hope I never lose this =/

happiness is relative

What makes people happy? Is it purely based on what situation they are in right now?

How do you explain those people living in the cities in apartments, with more than enough food and water to sustain a balanced diet, with access to the internet and mobile phones, who are more down with life?
And compare these people to the islanders who only eat whatever the fuck they can find but are happy anyway?

It's all about frames of reference, and if you do physics, this would help a lot.

Now when people say they have a "need for speed", I find this quite inaccurate. They actually have a "need for acceleration". There is no thrill in travelling at a constant velocity of 100km/h. It feels just as thrilling as not travelling at all. Like, if you've sat on a subway before (hopefully a line that doesn't have many turns), there is no thrill of shooting around underground at 60km/h. Because travelling at a constant velocity exerts no force on the body, and hence you don't feel a thing.

Now the true thrill is when acceleration is experienced, ie when taking a sharp corner or when just straight out mashing the accelerator. The acceleration experienced by the body will cause the thrill.

Now I think the same works for happiness. An improvement in one's current situation will result in happiness. If one's situation is good for an extended period of time, it starts to "travel at a constant velocity", and hence they feel nothing. They can feel satisfied, but it's much harder to feel happy.

What you need to feel happy is a massive change in perspective or frame of reference. Going on AFX was just the thing for me. We lived in hootchies (click to see a pic of one that looks much like the one I set up myself), lived on ration packs for 7 days, constantly got rained on and blown around by the wind, had to deal with pricky officers (I did, at least - Brian had cool officers =C). We didn't have any resources to wash clothes, bodies, or even properly wash our hands. We also had to constantly work to keep our cadets happy despite all this.

This was my frame of reference. And now here's the "acceleration".

Brian and I, on the last day of AFX, when battalion allowed us to chill and sleep with our own home units, set up a hootchie that was spacious (ie, large enough so we could comfortably sit up in). We ate a dinner portion about twice of what the meal plan suggests, and I had a can of Sprite. We brushed our teeth properly and took a dump.
We were, after 6 days, in contact with other Ruse kids. We could do whatever the fuck we liked for about 4 hours.

To us, that was luxury.

Reflecting on this, it's actually in quite poor conditions on the grand scale of things. We weren't clean, we were in a fucking tent (no matter how big), we only had dying torches and glowsticks, we had to walk about 300m to the toilet. But we were smug as hell and happy beyond belief. It's not because we were good on the grand scale of things. But the improvement in conditions was what made it so enjoyable.

So the analogy is:
Where almost dying is 0km/h
Where living in a small hootchie etc etc on the first 6 days of AFX was 20km/h.
Where the last day of AFX with larger hootchie and taking a dump, brushing teeth, etc was 40km/h.
And most of our current living conditions with ample access to running water, internet, etc is 80km/h

Most of us are cruising at 80km/h, and we don't feel a thing. Because a constant velocity has no thrill, and it actually feels the same as sitting in the same place. Now us cadets quickly decelerated to 20km/h (which was thrilling nonetheless, as deceleration is just negative acceleration). While this deceleration didn't make us happy, it did make us somewhat excited. So we cruised at 20km/h, feeling alright but not overjoyed, and when the speed bumped up to 25km/h (the sun was out YAY), there was distinct happiness. Then on the last day, we were bumped up to 40km/h very quickly, and that was a massive moment of joy (as happiness and acceleration are directly analogous).

The stop by McDonald's was a bump for the cadets up to 60km/h (but for Brian and me it was terrible because we weren't meant to stop), but you can tell how happy they were for the unexpected change in situation in such a short time.

So an increase in situation is analogous to an increase in velocity. And so acceleration is analogous to happiness.

Mathematically, if you differentiate distance (strictly displacement) wrt time, you get velocity. If you differentiate wrt time again, you get acceleration.
Similarly if you integrate acceleration wrt time, you get velocity, integrate again and you get displacement.
Now there is no suitable analogy for distance (situation is measured wrt time as well!), but velocity can be analogous to one's situation. If you differentiate the situation wrt time, you get happiness.
Similarly if you integrate the measure of happiness wrt time, you get the situation,

Hence happiness is defined by the measure of change in situation over time.
