Online Cheating

She goes by the name Jogann and for a price will do all of your homework!


jogann profile

But she’s not the only one. Dozens of so called “tutors” are available
for hire on the site JustAnswer.com. This site is supposed to be a tool
where you can ask a question, set a price, and then get an expert answer. However, it’s
commonly being abused by students who are looking to hire someone to do
their homework. At the bottom of this post is a screenshot of cheating in action.

Basically what happens is you upload your homework to a file sharing site (mediashare in this case), post your price, and then the tutor downloads it and completes the homework for you. Then the tutor will upload the complete homework to mediafire and post the link. Then after the student gets the answers, the link in the post is deleted so that no one else has access to the answers.

This is the perfect way to cheat, since, if your professor wanted to search for proof on the internet that you plagiarized, there is no way she/he will find your answers as it’s protected behind a LOCKED thread. Furthermore, if the professor found the thread and even paid the $3 to view the locked answer, then she/he still won’t find the answers you handed in, since the tutor already deleted the link to the answers.

Cheating is not fair to anyone but unfortunately is way too common (and pisses me off way too much – if I ever meet this Jogann, she’s getting a punch in the face).

Cyanide & Happiness Comic

Cyanide & Happiness is a very popular webcomic written by four different people.

Cyanide and Happiness, a daily webcomic
Cyanide & Happiness @ Explosm.net

It’s not a math comic but the above is the closest they got to having math in it ;-)

Silly Omegle Chat

Omegle is a site where you can chat one-on-one with strangers. The service randomly pairs up users online into one-on-one chat windows, where they can chat anonymously using the handles “You” and “Stranger”. Either party can disconnect at any time.

This particular chat is rather amusing:

Just don’t check the math ;-)

A few math jokes

Joke 1:

Four friends have been doing really well in their calculus class: they have been
getting top grades for their homework and on the midterm. So, when it’s time for the
final, they decide not to study on the weekend before, but to drive to another
friend’s birthday party in another city – even though the exam is scheduled for Monday
morning. As it happens, they drink too much at the party, and on Monday morning, they
are all hung over and oversleep. When they finally arrive on campus, the exam is
already over. They go to the professor’s office and offer him an explanation: “We went
to our friend’s birthday party, and when we were driving back home very early on
Monday morning, we suddenly had a flat tire. We had no spare one, and since we were
driving on backroads, it took hours until we got help.” The professor nods
sympathetically and says: “I see that it was not your fault. I will allow you to make
up for the missed exam tomorrow morning.”

When they arrive early on Tuesday morning,
the students are put by the professor in a large lecture hall and are seated so far
apart from each other that, even if they tried, they had no chance to cheat. The exam
booklets are already in place, and confidently, the students start writing. The first
question – five points out of one hundred – is a simple exercise in integration, and
all four finish it within ten minutes. When the first of them has completed the
problem, he turns over the page of the exam booklet and reads on the next one:

Problem 2 (95 points out of 100): Which tire went flat?


Joke 2:

A mathematician, statistician and accountant were finalists for a position as VP in a
large corporation. The hiring committee asked them all the same last question:

The mathematician was first.”How much is 500 plus 500 ?”, they asked.
“1000″ he replied
without hesitation.
“Thank you”, they dismissed him.

Next the statistician.
“How much is 500 plus 500?”
“On the average, 1000 with 95 %
confidence” replied the statistician.
“Thank you”, they dismissed him.

Next the accountant.
“How much is 500 plus 500?”
“What would you like it to be?”
responded the accountant.

They hired the accountant.


Joke 3:

Several people are asked to prove that all odd integers greater than 2 are prime.

Tenured mathematician: 3 is prime, 5 is prime, 7 is prime, 9 is not prime. Ha! A
counterexample.

Statistician: Let’s verify this on
several randomly selected odd numbers, say, 23, 47, and 83.

Computer programmer: 3 is prime, 3
is prime, 3 is prime, 3 is prime…

Politician:
Shouldn’t the goal really be to create a greater society where all numbers are prime?

Sarah Palin: What’s a prime?

Best of MLIA

My Life Is Average (MLIA) is a site where you can submit average things that happened to you. Here are some of my favorites:

Today, I got the results of a math test. One of the answers was (2, infinity), and on the side I wrote “and beyond!” I got extra credit. MLIA

Today, we were taking a math test when someone’s cell phone rang. It was dead silent
as we heard, “my milkshake brings all the boys to the yard…” Everyone looked around to see whose phone it was. It was my teacher’s. My teacher is a man. MLIA

Today, we got our math tests back after being graded. One of my answers I knew was
wrong, so I had drawn a stick figure next to it with the caption “this is a ninja in
disguise. He is here to guard my answer from the Red Pen.”. Next to my answer my
teacher wrote “you need a new ninja.” He had graded my test in blue. MLIA.

“Today, on MSN, I mistyped something to my boyfriend: I said, ‘You’re such an angle,’
but I meant ‘angel’. Without missing a beat, he replied ‘Aww, you’re so acute. MLIA.”

Today, in my calculus class, I sat like normal listening to the lecture and taking
notes. Out of nowhere, I get passed a note from the guy next to me. The paper was
covered with drawings ranging from flowers to aliens and at the top it said, “Everyone
draw something.” The note went around the room multiple times. Glad to know I’m not
the only one bored in calculus. MLIA.

Dudeney numbers

This is pretty neat. A Dudeney number is a positive integer that is a perfect cube such that the sum of its decimal digits is equal to the cube root of the number. For example:

5832 = 18 x 18 x 18… and 5 + 8 + 3 + 2 = 18.

How many such numbers do you think exist?

Well, it turns out there is exactly 6. They are: 1, 512, 4913, 5832, 17576 and 19683.
