Chaser 2010 Election Song Lyrics

admin — Thu, 19 Aug 2010 22:49:58 +0000

This was fabulous. If you haven’t seen it already, watch it on iView RIGHT NOW!

And so we face election day,
each leader take their stand.
The question is to vote which way,
the future’s in our hands.
We may ponder on their policies
before we hit the booth,
trace through each party’s history,
discern the hidden truth.
Who should we write as number 1,
which canditate should lose?
There’s only one clear answer
when it comes time to choose.

They’re all fucked.
They’re all fucked.
Every single one is fucked.
There’s nobody to vote for ’cause they’re all just fucked.
One’s a ranga born in Wales.
One’s a backward sexist male.
And you wouldn’t vote for Greens,
’cause all the do is fondle whales.

Each [] and every candidate is fucked.
You’ve no voice.
There’s no choice.
Every single one is fucked.
Ignore any disagreeing statistics.
Every one is fucked.
One’ll stab you in the back.
One’s a bible bashing hack.
You’d might as wipe that fucking ballot on your crack.
Every single candidate is fucked.

The majors’ fucked.
The minors’ fucked.
Every single one is fucked.
The futures fucked.
The world is fucked.
All of us are fucked.

I don’t want to fuck your hopes.
But we’d [] a fucking rope.
In fact, we’re even more fucked than those refugees on boats.
Let’s face it: every candidate is fucked.
This one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
This one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.
And this one’s fucked and this one’s fucked.

Hold on! Hold on!
I’m not anymore.

Yes you are!

Every single candidate is fuccccccccccccccccked…

hurf durf Biology Time

admin — Thu, 18 Mar 2010 04:41:20 +0000

This time I’ll be following the syllabus so it’s not such a huge mess, but still keep in mind “surface area to volume ratio”, “energy conservation” and “water conservation”.

1. Evidence of evolution suggests that the mechanisms of inheritance, accompanied by selection, allow change over many generations

OK. Read that again carefully. The key words this time are “evolution”, “inheritance” and “selection”. Maybe even evidence, but that’s not as important.

Now, 1st column 1st dot point:
Outline the impact on the evolution of plants and animals of: changes in physical conditions in the environment; changes in chemical conditions in the environment; competition for resources.

The directive term outline means to do a brief blog about it without excessive detail or specifics, so here it goes:

Changes in physical conditions in the environment have caused plants and animals that are better adapted to the new conditions will be naturally selected to survive and pass on their characteristics when they reproduce, thus impacting evolution by changing the dominant set of characteristics within the population. (You can just do a search and replace for chemical).

Increased competition for reasources will mean that natural selection will take place and favour the survival of those in the population with characterisitcs that can most efficiently acquire and utilise the available resources. (Insert the bit from above about how it = evolution).

Onto the 2nd column 1st dot point:

Plan, choose equipment or resources and perform a first-hand investigation to model natural selection

You should’ve written up your prac! >:(

Anyway, you have some pieces of paper with 3 different colours and you roll a biased dice X number of times to kill a member of the population. You then go to the reproduction step. Someone has to close their eyes and pick 2 pieces of paper at random. If both are the same colour, and it’s one of the “pure” breeds, then they will produce an offspring that is that colour. If it’s a hybrid + a pure, then you roll for a 1/2 chance (IIRC) of a hybrid and 1/2 chance of a pure. If it’s a hybrid + hybrid, you roll for a 1/4 chance each for a pure and 1/2 chance for a hybrid.

Basically, a certain “pure” colour had a higher chance of death (red, IIRC) because they were supposedly not adapted to the environment.

How will this be asked in the exam? No idea. Just looking through the 2008 paper, it didn’t seem to be there.

Next!

Analyse information from secondary sources to prepare a case study to show how an environmental change can lead to changes in a species

Now this is quite a long blog. Time to break it down by KEY WORDS.

Analyse: That’s sorta like comparing screenshots from encodes. You’ve got to note down and compare the information then make and write down your judgement.

Secondary Sources: Wikip- err… Text books, internet sites, lolscientificjournals, non-Wikipedia Encyclopedias.

Case Study: Take an example and blog down whatever you can about it.

Environmental Change/Chance in Species: In HOLY BRITTANIA they started the lolindustrial revolution, which meant that there’s volumetric fucktons of smoke everywhere, which meant that predators of moths would find it harder to, and hence not bother (unless they were trolls) to, kill the ones whose colour blended in with all that pollutantant. Due to that process of natural selection, more of those smoke-coloured moths survived and reproduced, therefore they become more dominant in the species, therefore there has been an overall change to smokier colours in the species.

Since Biology isn’t lolimpression marked, there’s no need to be original. The typical 99%-of-the-state case study will be fine.

Whew. That was much easier than the Eco case study.

describe, using specific examples, how the theory of evolution is supported by the following areas of study:

- WHATEVER

I doubt they’ll specifically ask for some pretentious obscure one, so we’ll just use the PENTADACTYL LIMB, since once again, there’s no marks for originality. Basically they’re in basically every man and his dog, even birds and fish-like mammals, etc. Each part is slightly modified such that it provides an adaptive advantage in the environment that they live. Example: birds have omega long fingers (phlanges if you want to be pretentious) for A+++++ feather coverage. Don’t forget, of course, to link back to how that = evolution (the usual crap about some trait become more dominant).

You can also say some crap about DNA hybridisation and how humans and apes and summoned beings evolved from the same ancestor.

Next!

Use available evidence to analyse, using a named example, how advances in technology have change scientific thinking about evolutionary relationships.

Oh right, the DNA hybridisation crap was meant to go here. Basically, they take DNA from 2 different species and heat it to over nine thousand kelvins so that the double helix un-whatevers, then they take a strand from each species and cool them together and see how well they bond, and they get a quantitative result. This totally radicalised thinking because it showed that humans were closer to primates than apes (or something).

Back to 1st column.

Explain how Darwin/Wallace’s theory of evolution by natural selection and isolation accounts for divergent evolution and convergent evolution

Divergent evolution means that from a common ancestor, the descendents become less and less alike one another with time because if a population is split and isolated, genes cannot flow, and as such, their evolution will be dependent wholly on the selection pressures in their particular respective environment, causing characteristics favourable in the particular environment to be passed on through the generations (and therefore = evolution, blah blah blah)

As for convergent, no idea. Need to check notes… Dongs. Not there. Need to check HSC Online. Here’s some copy pasta:

Convergent evolution occurs when two relatively unrelated species develop similar structures, physiology or behaviours in response to similar selective pressures from similar environments. For example, dolphins (mammals) and sharks (cartilaginous fish) have evolved a streamlined body shape and fins that enable them to move efficiently through their aquatic environment, yet they are only remotely related as vertebrates. Communal social behaviour has developed independently in ants, termites and bees.

OK. Onto the next section, because I’m SICK of this year 9/10 rehash junk.

2.Gregor Mendel’s experiments helped advance our knowledge of the inheritance of characteristics

Actually, I think we never got to this…

OK, back to maintaining a balance.

Our best friend, the enzyme:

Each type only does 1 think and they’re A++++++++++ good at it. They only do 1 thing, so that your body can micro around all the chemical reactions that are happening (ie. it can affect 1 particular thing by simply changing 1 particular enzyme without directly affecting other stuff).

How does it work?

It’s randomly shaped and the substrate fits exactly in it (lock and key) or it ALMOST fits exactly in, then once it tries to fit, it changes it’s shape a bit to MAKE it exactly fit (induced fit). TBH, the 2nd model is probably more correct, but we don’t care because the first one is easier.

How does various :stuff: affect enzyme activity?

- Temprature +++ = +++, until the point the enzyme gets borked (denatured) at which point it becomes instantly zerox
- pH. Pretty acidic = good for most enzymes. I’m sure there are exceptions, but most likely they’re just gonna give you a graph or something so you can read it right off for a free 1 or 2 marks
- Substrate concentration. Obviously if it’s got more stuff to do, it can do it faster until it reaches 100% CPU utilisation, then it doesn’t get any faster even if it does get more stuff to do.
- Errrr… Forgot the rest. Oh, according to HSC online, that is all. Great!

Now for homeostatis. That thing we all love to hate.

It works on the concept of NEGATIVE FEEDBACK which means that your body acts to oppose whatever change is happening. Eg. if your water levels are getting low, it tries to conserve water. If your energy is getting waste it, it tries to conserve it. (Yes, my magical answers are still relevant!)

You’ll most likely need an example, so I’ll use temperature since I can’t be assed remembering anything else. Basically when temp rises/drops, your fabulous hypothallamus detects the change, then it can send electro-chemical messages through your nervous system at approaching the speed of light, provided you don’t have cistic fibrosis or similar, to your various body parts to take actions to oppose the change. Eg. if you feel hot, you will subconsciously sweat, fan yourself, turn on the air conditioner if you can affort one, etc. If you feel cold, you will feel ever colder because your body directs the blood away from the surface of your skin to keep it’s insides warm. Your hair would also stand up (more noticable in some parts than others ) to trap air, which is a super A+++++++ heat insulator.

You may or may not need/want to know a model, so just think a thermostat. It’s limitations? It can’t adapt to :long term: variations.

Done. Next. Derp, can’t remember what’s next, gonna take a break. Blagging is tiring work.

Trackerless Torrents, DHT, Peer Exchange and Magnet links

admin — Sat, 21 Nov 2009 05:13:25 +0000

Basically, some article I read on TorrentFreak seems to give me the impression that they’re the best thing since sli- torrents, so I decided to give it a try.

I made a torrent of a small file (< 256 KiB) with uTorrent 1.8.4 and used TorrentSpy to extract the infohash and plugged it into a magnet URI as follows.

magnet:?xt=urn:btih:7e1e4c13d8726730a1982b877c4a310908789b0d (By the way, feel free to (try to) download that to help my testing)

I set uTorrent to seed that torrent and I added the magnet URI to uTorrent on my server.

Currently (30 minutes later), my home laptop and my server have yet to find each other over DHT.

FAIL!

Bio Notes

admin — Mon, 21 Sep 2009 09:39:00 +0000

Cos I’m that ownage at bio! Well actually I suck, so yeh, take these notes with a grain of salt and citations are needed for everything unless otherwise stated.

First matter:

Darwin’s Theory of Evolution or Natural Selection or whatever you want to call it

Basically some smartass called Darwin travelled around the world and co-incidently went to the somethingorother-gas Islands where he found that stuff was like totally different to everywhere else. Some other guy also did something to do with it but no one cares about him because Darwin was more popular or something. By the way, you didn’t need to know that.

So how it works is as follows:

Due to the chaos theory, or whatever you want to believe, not every member within a species is identical in terms of genetics and traits. (It’s probably too late to tell you this, but if you click that Wikipedia link you may get trapped for a good hour or 2 link clicking)
Thanks to the environment which may also vary for some reason or another, some variations in the species allow them to survive better
Since they can survive better, they get to have more sex and have more babies (and vice versa for the environmental suckers)
Eventually that environment will be overrun by members of the species with the more ownage characteristics
Done

Some other theory states that some random individual in the species had some “inner will” and they magically changed some of their characteristics to be more favourable in the environment they are in. That’s total bullshit and it’s no wonder it was never accepted.

Why… questions

The answer will almost always be “water conservation” or “energy conservation”. Not forgetting “surface area to volume ratio”.

Photosynthesis

Chloroplast is very important. It also needs carbon dioxide and you’re probably meant to know the equation for it but I forgot. TODO: go back and write the equation here.

Mitosis

Chromosomes duplicate
Chromosomes line up
Cell splits
???
Profit

Meiosis

Chromosomse duplicate
Chromosomes line up
Cell splits
Cell splits
Profit

And apparantly you don’t need to know the whateverphases, so we’re all good.

Life on Earth

Hopefully you still remember it from earlier in the year, because I don’t.

Stuff before Life on Earth

Hopefully you still remember it, because I don’t, but fortunately it’s not needed.

Sexual Encounters of a Floral Kind

It was a seriously great VHS, and I want to archive it in Blu-Ray quality.

Basically you have to remember that the stigma, the style and the ovary are the female parts. (Make sure you get it right, because I keep getting stigma and stamen mixedup). Anther and filament are the male parts, collectively known as the stamen.

Apparantly plants can incest and they don’t seem to think there’s anything wrong with it, but the male and female are mature at different times to try to prevent that. You don’t need to know that.

So there are 2 main ways to get the male part of one flower to the female part of another. I’m sure there are exceptions where the reverse occurs but I don’t know any.

Wind
“Pollenators”

For wind pollenated plants, under a microscope you can see that the pollen is like spiky so it can easily stick to stuff. That was something you probably did need to know, since they will probably ask questions on practicals to screw over people that didn’t pay attention in practicals. Basically, wind pollenation advantages are:

Energy saving (see, I told you this would be the answer to everything) because it doesn’t need fancy flowers to attract picky pollenators
No need for pollenators

Disadvantage(s):

Very small chance of pollen actually landing somewhere useful (though I beg to differ, since it successfully gets up my nose quite often). Just think of the inverse square law, kinetic particle theory, or whatever other equivalent.

I’m now only 200 words from this being longer than my English essay.

Bascially with plants that need pollenation by “pollenators”, it does all this fancy energy consuming stuff to attract “pollenators” so that they can get their pollen all over them. (I’m sure you can draw your own parallel for this (; ). Some examples of the attractive stuff it does:

Nice odour (to the pollenators, sometimes to humans as well, not that humans are necessarily not pollenators)
Free food
Nice colour

———— I’m gonna continue after I take a shower.

When I finished showering I got distracted my MSN, IRC and some other crap. I don’t feel like doing any more on this now…

OK so disadvantage of pollenator requiring plants:

Wastes energy

And now onto…

Asexual Encounters of a Floral Kind

BOOOOOOOOORING!…

is what I would be saying if someone actually decided to make a video with this name.

Basically a plant sprouts new bits of itself in varying places and becomes a seperate plant.

Bulbs. Think onion…
Stolon. Think, the ground is stealing a part of the old plant.
Runners. Like a stolon, but the original plant specifically sprouts out new bits for the ground to steal.
Rhizome. No idea. Just think ginger. Delicious.
Suckers. Err… new bits come from the base of the old plant, go out sideways and go up. (I can’ t be bothered with a diagram)
Stem tuber. An underground stem with a massive chunk of shit on it.
Root tuber. Same thing, except that it’s the root.

This worksheet I’m using as reference asked why weeds are so successful. Answer: because they‘re ownage reproduce by asexual means, which are very fast.

Also, humans like this because they won’t get any variations of the food which are yucky, since each plant would be identical.

Continental Drift

Stuff moved, climate change, environment change.

Evidence: fitting continental shelves, similar fossils, etc.

Good/bad? Doesn’t matter.

EDIT: I just found a sheet that says that continental drift causes geographic isolation which prevents gene flow (read: sex) between the seperated groups, therefore they will evolve differently over time.

Megafauna

Sucks to be them. They died due to either

Ill
Kill
Chill

(in order of the number of letters in the word). Apparantly just writing the word in the exam will get your zerox marks, so you need to explain it. Taking the first one as an example: Those evil evil humans brough disease beacase they decided to migrate everywhere and sneeze on everything they saw. Evidence is that there are human fossils of a similar age and location to megafauna fossils.

Classification

All classification systems are arbitary, which means the maker of them randomly bullshitted up some criteria and put on the fancy label of “classification system”. Main criteria in ye olden daiz are appearance and physical features, but thanks to some technology, we now use some chemical thing since we think it’s less subjective or something.

Hierarchy (commonly accepted because we’re stupid): Kingdom, Phylum, Class, Order, Family, Genus, Species. (KPCOFGS: Keep Pond Clean or (Ice)Frog Gets Sick). You probaby didn’t need to memorise that, but thanks to Google/UrbanDictionary for the mnemonic.

Dichotomus keys are the best cos they’re totally unabigious, but making them are a pain in the ass, but luckily we will only have to make a really simple one, if any, in the exam.

OK, that’s it, I need sleep. Good luck and have fun for tomorrow!

So basically the jist of it is.

You have a VPS that uses HyperVM (which means close to all VPS companies out there).
Someone else on the same HyperVM installation finds out about this.
They root the physical box.

PROFIT! (for the hacker)

I for one have backed up all the (important) shit that I had stored on any HyperVM based VPSes, and I recommend you do the same.
