Oil Skimmer Obama

Add a new nickname to the political scene. Alongside "Schoolbus Ray Nagin" we now have "Oil Skimmer Obama."

Senator George LeMieux has brought it out into the light in indisputable fashion, the President has made himself as much an obstacle to dealing with a disaster as Mayor Ray Nagin did in the disaster his city suffered. In fact, he's done worse. At least Schoolbus Ray didn't keep turning away schoolbuses after allowing his own fleet to be flooded out.

Oil Skimmer Obama reassures his hand-selected politicians that oil skimmers won't spoil their view of oil-soaked seas.

No matter what the President says about the value of oil drilling and offshore oil production (which he appeared to support with political actions taken just before the BP oil spill), we have a big spill now. It's possible to deal with this spill. The means for doing so are proven and in hand. But he's stood in the way the whole time, first through inactivity then through outright opposition.

Check out the Senator's page for the details on the oil spill response.

Phreak Your Final Exam Tests!

Crush the Curve!


Here's the tried and true technique for beating out the Final Exam. It beats the grading mechanisms. It's an end-around, a secret handshake. It's the push of the button that ain't supposed to get pushed.

The Standard Substandard Method


OK, you know the drill. You're given a syllabus with the grading breakdown for your class. So many percent for this, so many for that, yadda yadda.

It'd work fine if you only ever took one class at a time. But every teacher expects you to build your entire life around their class. It doesn't matter if it's a five unit lecture plus three unit lab, or a two unit time-filler in underwater basket weaving. Your time belongs to them.

So they bleed you. Time for lecture, time for quiz, time for studying/revision, papers, midterms. A pint at a time, four to six time vampires attached to you, leaving you bloodless and limp just in time for finals.

So here's how to fight them.

Phreak the Final Exam!


First, you gotta know this technique ain't gonna get you in the honors society. It's gonna get you a passing grade, that all. But if you're in a position where that's in question, that's good enough, right? Especially if you can do it to more than one class where passing is in doubt.

Sometimes You Gotta Lose to Win


First, pick and choose what matters. Chances are, what really matters are the midterm and the final exams. The rest is blood taps. So, here's the deal. You're going to ace the final, possibly the midterm (if it's not already too late), skip the rest and retire with a cool 'C'. On top of that you'll still have a life, a body, and probably more real knowledge than if you'd flogged yourself to death on all the filler work. Heck, you may not even waste your time on classes any more.

How?

Yes, I have actually done this.


Guess what? Your college is not the only place in the world to learn things. In fact, most government-run schools (and some private ones) are among the worst places to learn. They do provide resources...labs, clubs where students of like interests can get together, libraries, they act as focal points for bookstores in the community, and so on. All this good stuff is what they hide lousy, boring curricula behind. The textbooks are chosen by crooked committees more interested in kickbacks than the quality of the material, the professors and instructors do what they can, but they have an administration forcing all sorts of requirements on them to satisfy the demands of people who have nothing to do with what you really want and need out of your education. And let's face it, some of them have either given up or weren't all that hot to begin with.

So, let's go where the knowledge is. You're not stupid, and you're not against learning. You're just against spreading five minutes of information across several hours of dry tedium.

Take your subject. Chances are you already know something about it and what it's for. There may even be an interest in your part. Sometimes the real use of a school subject is deeply buried, but it's there.

Now go where the people who use that subject actually learn it, or share their love of it. It's not school! Find the articles online, find the books writtten by interesting authors (there are interesting authors who write textbooks, but you wouldn't know it when the textbook editors finish with them.) Find a textbook from 50 years ago, when results were still expected and people were still naive enough to think that knowledge can be fun and interesting.

Now learn. Really learn. Have fun doing it. Fill your head with it and play with it. Make things, test ideas, play at being a crackpot with a wild idea about your subject. Build intellectual castles, then move the surf over them.

Know your subject cold, from the best perspective possible--that of someone who knows it for the sheer joy and love of it.

Guess what? This takes less time than classes and homework. Stay cool, and stay with it. Keep looking for the good stuff.

The Final Exam


Then, walk into the final an expert on the subject. You've used it. You've done it. It's yours. Know more than the teacher. Recognise the mistakes in the way the questions are asked, and anticipate what it is they're looking for rather than trying to search your memory for some comment from class you can parrot.

I have done this.

I got a C every time I did it.

I never went to any class but Final Exam for some classes, both Midterm Exam and Final Exam for others.

I never failed.

In most classes I had the highest score in the class on the final (or a tie for highest.)

And I got to have fun reading things I enjoyed reading, playing with ideas on paper, writing simple programs to play around with math, or languages, or history, or whatever as a way of playing with the concepts I was actually learning. I not only knew the bare facts, but why they were that way. If I forgot something, I could remember everything around it and piece it out for myself--while staring at a final exam paper.

Crash and Burn


OK, it's a scary idea. And fear will kill you. It shuts off the brain, keeps you from settling in and learning. And the potential for failure is huge if you can't be trusted to be honest and firm with yourself.

Accept failure. Fear nothing. Just learn because you want to. Perhaps start before you actually enroll in the class--you knew you were headed that way, right. Then you'll have your feet already under you once class starts. You might even enjoy class time, since you'll have something interesting to discuss with the instructor (and maybe even liven things up for your classmates.)

It's not necessary to start ahead of time. I often didn't. When I did, I often ended up showing the teacher my knowledge and interest so strongly at the start of class that they took me aside to make a special deal. In some classes the teachers sounded me out, then said "Here's the deal, I'll just give you an A in the class if you'll..." In one case I was asked to tutor a sports player who was struggling with staying on the team, in another case I was asked to write some articles for the school paper. How's that for a grade exploit?

Live and Learn...and LIVE!


Anything, anything, that makes you stand out from the muddled mindless masses in your class will mark you to your teachers. So long as they don't have some inferiority complex (many do), they'll welcome the difference in you.

And even when they don't, don't let them draw that life out of you.

Beat the system. Learn with enjoyment, control your time and your life. Pick your own way, get recommends from others who actually love the subject (your instructor may be one of those, ask and see!) Spend less time and get more, and get a passing (or better, maybe) grade.

And walk out with not just a diploma, but a mind filled with the joy of understanding.

Guam Tipping Over: Use a Skyhook!

He had the answer to global communications. Perhaps he saw how we can save Guam from tipping over?


There's a Congressman who's deeply concerned that Guam tipping over. He's shows a great degree of concern for the inhabitants of the island, and rightly so, given the nature of the threat to them this would pose.

Something must be done. We must understand the problem, then find a solution.

Stress Test the Islands


Maybe he's onto something that the rest of us are blinded to by our "conventional" thought, however. In the spirit of leaving no stone unturned, I think it's important that we start doing careful tests of the islands managed by the U.S. to make sure they won't tip.

First, we need to clear paths between the two sides of some of our smaller islands--across the narrow way, of course. Then, have the population march from one side to another while satellites measure the amount of movement. Perhaps draw them there with free beer and soda. Once they've sated themselves on one side of the island, open up restrooms on the far side. Put out bowls of chips and popcorn, then they'll be back at the sodas soon.

Careful measurements should allow us to figure out which islands need to have outriggers and pontoons attached to them for the safety of their population. Perhaps this would be a good reason to develop the "skyhook" technology Arthur C. Clarke was talking about. It would:
  • Steady the island, and hold it up if necessary (perhaps raising it above tsunamis!)

  • Provide a convenient navigational reference to islanders travelling in traditional means, without GPS aids.

  • Boost the local economy, allowing the locals to lift satellites to orbit without the use of noisy, expensive, and ecologically unsound rockets.

Sounds like a win-win-win scenario!

The Real Concern

I'm more concerned about the Congressman, myself. From the sounds of things he should be getting medical care, rather than being sent to Congress. He's got real mental problems with a medical cause, and it's unfortunate that he's being used this way by those around him.

What's the excuse for the people who elected him, the people in the party that put him in this position, and those people that call themselves "reporters" in his district?

Actual Scantron Exploits

Chapstick don't work. Face it, fiddling with the Scantron form is going to get noticed, especially if it makes it sticky. And guess what? It won't spoof the reader, either.

Light lines across the bubbles, or shading? OK, now you're just rolling dice on whether the scoring machine is going to pick up a right answer off one of those--and not a wrong one, or a double-mark (insta-wrong!) You're better off with a blind guess!

Cutting the form and other such nonsense will just get you into academic probation.

What to do to beat the Scantron?

Before The Test: The Ultimate Exploit


Pre-test prep is crucial when you're graded on the curve. Spread crap about the Chapstick and form-spoiling exploits among your classmates. Send them to websites about it, hand out chapsticks and exactos and colored pens before the test, show them a (dummy) hacked form of your own and tell them how cool it is. Make crap up about sucking a Mentos and licking the form, or spilling green tea then drying it in the oven. Whatever.

Then, when their Scantrons get bounced and flagged, you'll be golden!

Now, let's get real...

Play the Test, NOT the Tech


First, don't try phreaking the Scantron form reader unless you're the one working on it and running the tests through. Different readers work differently, and most spoofs are going to either get the form spit out, get the form marked wrong, get ignored, or hose the machine.

None of these gets you what you want, and two of them put your spoofed Scantron sheet in a human's hands where trouble starts. Not good.

So, first, don't eff up the form. When you know an answer, don't screw up marking it. Use the right pencil and mark it properly. Exploits are worth nada if they take away what you can do right (whatever that may be.)

Working the tech is asking for trouble. It leaves a trail marked "this way to loser." So...

A scantron is just a multiple choice test. MC tests have been getting worked since they've been given. Scantron neither detects nor corrects these techniques. They leave no tell-tale marks on paper. And they can turn failure into hope for survival (which you don't have otherwise, or you wouldn't be looking up hairbrain schemes for putting lip wax on your test form on the internet, right?)

First, how's the test scored? If you don't know this, learn it or drop the class. Are blanks ignored or marked wrong? Does a blank count against you more than a wrong marked answer? How many points do you get/lose for each right/wrong/blank?

Let's say blanks are worse than wrong marked answers. You are now a wild guessing machine--no answers goes blank. See below for cutting down on the wrong guesses.

Wrongly marked answers are worse than blanks? Mark nothing on the Scantron that you either don't know or haven't got a strong guess on--keep reading to fill in as many bubbles as you can...

Exploit the test as follows:
Go through the whole test fast, answer only what you're sure of. Often the answers for some questions are built into others.

Watch for tricky words "are not often mainly" "less regularly than at first" and garbage like that can wait. Skip it and do fine parsing later (if at all.)

Go back, picking up anything that a later question answered. Get the marks in the right freaking bubble! Do not get half the test off by one then discover it too late!

It might seem risky to bounce around the test, rather than going top to bottom one by one, but really your chances of picking up an off-by-one bubble row shift is better this way, and you'll affect less of the test if you do it. Few things such as bad as having to move 300 test bubbles up one when you're moments away from "pencils down".

How many possible answers are there on the questions you have left? If it's two it's worth guessing, especially if you've got even the faintest clue of which seems better.

If it's more, throw out the howlers. If you can get it to two, you're in guessing territory even for a wrong mark is worse than a blank. Once you've done this as far as you can, sweat your way through as many blanks as you can in the remaining time.

If a blank is worse than a mark, get it to three possibles and guess. Then finish off with your totally random shots in the dark. Flag the total guesses, and use any extra time to go back and see if you can eliminate any of the answers you've marked as wrong. When you do, pick another of what's left.
