Signature Opportunities

[David Martorana]

Dearest Pledges:

The following tasks are first come, first served. Please read the instructions carefully before you claim a task. You may "Reply All" to the listserv (except for brainteasers) so your fellow Pledges are aware of which tasks have already been claimed. I will provide additional signature tasks later in Pledge, but the difficulty of my tasks are a negative function of time remaining in Pledge. 

I. 48 LAWS OF POWER

1) The first three (3) pledges who volunteer to (jointly) develop a 10 min PowerPoint to deliver to their class on the book linked below (you don't have to read the entire book, but follow the link below and read a few online summaries) before the end of pledge will each get my signature. You must already have your group of three established when you sign up.

2) The first (1) pledge who volunteers to read the entire book and develop a (engaging) 10-20 min PowerPoint to deliver to their class by the end of pledge will earn my signature and be exempted from up to 5 other signatures, depending on the quality of the presentation.

First-come, first-served: option 1 and option 2 are mutually exclusive.

II. FURNITURE MODIFICATION

3) The first (1) pledge with artistic talents who volunteers to lead (plan, coordinate, take responsibility for) the modification (mostly painting) of a multi-purpose Scale and Coin furniture item with the help of the entire Pledge class will receive my signature and be exempted from 3 other signatures. You will not be responsible for paying for the materials used on the project.

III. NAMES QUIZ

4) The first (1) pledge who volunteers to coordinate, administer, and grade a quiz on the names of every other pledge no later than Midcourt will each receive my signature.

IV. BRAINTEASERS

5) The first (1) pledge who solves the following brainteaser and sends me a coherent explanation will receive my signature. If I find out you Googled the answer or cheated in any other way, you will earn a strike and the honor of five additional mandatory signatures.

There are 1000 bankers in a room--500 of which have brown feathered hats and 500 of which have black feathered hats. They are forbidden to communicate with one another or take their hats off. There are no mirrors or reflecting surfaces in the room. Because of an unspoken rule that all of the bankers understand and abide by, if at any time during the course of the day someone discovers the color of the feather in his hat, he or she must leave the room at midnight that evening. Every person in the room is a perfect logician, can see the color of every other banker's feather (except his or her own), and knows the number of bankers in the room at any given time.

One day (when all 1000 of the bankers are in the room), Ben Bernanke who wears a white feather, walks into the room and proclaims, without looking at any specific banker, "I see a banker with a brown feather," and then sits down in a corner, refusing to answer any other questions and abiding by the same rules as every other banker in the room.

The question is when, if ever, do any of the bankers leave the room? What color feathers are they wearing? How many leave?

6) The first (1) pledge who volunteers to correctly explain the solutions to the following 3 brainteasers to the entire pledge class (email is OK) will receive my signature.

(a) I have two buckets - one filled with Sprite and the other filled with Coke. The volumes of Sprite and Coke are equal. Using a standard Solo cup, I scoop one cup-full of Sprite out and pour it into the Coke bucket. I mix the Sprite-Coke mixture until it is of equal composition throughout the bucket. Using the same Solo cup, I scoop one cup-full of the Sprite-Coke mixture out and pour it into the pure Sprite bucket. I mix that mixture until it is of equal composition throughout the bucket. Which is greater: the concentration of Sprite in the Coke bucket or the concentration of Coke in the Sprite bucket?

(b) I have a tap, a drain, a 3 gallon bucket, and a 5 gallon bucket. I can get unlimited water from the tap and pour unlimited water down the drain. Using only these items, how can I measure 4 gallons of water?

(c) I have a string and a lighter. The string burns from one end to the other in 30 minutes but not necessarily at a constant rate (i.e., the first half might burn in 5 minutes while the second half burns in 25 minutes). How do you measure 15 minutes time?

V. FINANCE KNOWLEDGE

7) The first (1) pledge who volunteers to teach their pledge class the causes, effects, and proposed solutions for the European Debt Crisis will receive my signature and be exempted from up to 2 other signatures, depending on the quality of the presentation.

8) The first (1) pledge who volunteers to learn how to correctly conduct a DCF analysis and teach their pledge class will receive my signature and be exempted from up to 2 other signatures, depending on the quality of the presentation.

got task 5

[Rebecca B. Xu]

Hi all,

Explanations for the 3 brainteasers! :)

a)

 suppose there are 10 cups of coke/sprite in each bucket at first. 

after scoop one cup sprite into coke bucket, the sprite concentration in the  coke bucket will be 1/11 (10 cokes and 1 sprite)

then, after scoop this new mixture into the pure sprite bucket, the coke concentration will be (1-1/11)/10=1/10

so the concentrations are the same.

b)fill the 3-gallon bucket twice and pour it into the 5-gallon bucket, then one gallon of water will remain in the 3-gallon bucket. pour the water in the 5 gallon bucket out and then pour the one gallon of water remaining in 3-gallon bucket to the 5-gallon bucket. then fill 3-gallon bucket again, and pour it into 5-gallon bucket, finally we will get 4 gallons of water in the 5-gallon bucket.

c) it takes 30 mins to burn when starting from one end, then if we start by burning both ends, then it will be 15 mins.

Best,

Rebecca Xu

Hi all,

sorry for the bombarding your email! 

i just realized i had a typo, the coke concentration in the sprite bucket should be (1-1/11)/10=1/11, instead of 1/10.

Sorry about confusions!

Best,

Rebecca Xu

Hi all fellow pledgers,

I was surprised to see one of the pledge brothers, Rebecca, has submitted her version of solutions prior to me, as I was a little confused over the rule of "first come first serve". However, I discovered later that for the brainteasers, the criteria for earning credit are 1. first to come up solutions 2. it has to be correct. I had my own version of solutions before Rebecca submitted her answer, and I found my solutions differ from that of Rebecca Xu, mainly for the part (a). Thus, I would like to take this great honor, and share with you guys my answer. 

(a). The concentration of Sprite in Coke bucket is larger than the concentration of Coke in Sprite. 

We may safely suppose that initially both buckets have 5 cups of soda or sprite. Once the Sprite is scooped out, and poured into Coke bucket, the concentration of Sprite in Coke bucket is unchanged regardless of how many scoops you take from this newly mixed solution. The concentration of Sprite in Coke is 1/(1+5)= 1/6. Then, as we examine that one scoop is taken from the mixed solution(essentially the same mixed solution), 5/6 of the scoop is Coke, and 1/6 of the scoop is Sprite. When it is poured into the Sprite bucket, the total volume of liquid in Coke bucket remains unchanged in comparison to the initial state, as one scoop is poured out, and one scoop is poured in (which means the total volume is 5, still). However, the amount of Coke, now in the Sprite bucket is 5/6 of the cup, as I have explained above. Thus, the concentration of Coke in Sprite would be (5/6)/ 6, which is less than 1/6. 

(b). fill the 3-gallon bucket twice and pour it into the 5-gallon bucket, then one gallon of water will remain in the 3-gallon bucket. Clear the water in 5-gallon bucket, and pour the 1 gallon water remaining in 3-gallon bucket to 5-gallon bucket. Finally, fill the 3-gallon bucket, and pour the water in the 5-gallon bucket. Adding the previous 1 gallon water just transferred, this would give 4 gallons of water in the 5-gallon bucket.

c)  15 mins is the time that it takes to burn the entire string by burning from both ends.

Suppose the length of string is L. Burning from one end takes 30 mins, thought the speed of burning is unknown, the average speed of burning is L/30mins. Since we want 15 mins, thus we need to come up with a way to double the average speed. Thus, burning from the both ends would double the average speed, and given the fixed-length-string, the time would be 15 mins, which is half the original time. 

If there is any confusion in explaining, please let me know. Thank you!

With regard,

(5)

Answer:
On the 500th night; brown; 500.

Explanation:
Ben Bernanke makes it clear there is at least one brown feathered hat. If there is exactly one, the one who wears it will see the rest of them don't wear brown, so he knows he wears brown and will leave on the first night. If there are 2 brown hats, either one of them will see only one with brown, and he will not leave since he isn't sure weather he himself wears brown or not. If the other doesn't leave the first night, he will know he himself also wears brown so he will leave the 2nd night. If there are 3 brown hats, any of them will see 2 with brown, and nobody will leave during the first 2 nights since nobody can be sure whether he himself wears brown. On the 3rd night, since the other 2 haven't left after two nights, he will know he himself also wears brown so he will leave the 3rd night.

...

Since there are 500 wearing brown hats, any of them can see 499 people wearing brown hats, and nobody can be sure whether he himself wears brown for the first 499 nights. On the 500th night, any of the 500 wearing brown will know he himself also wears brown, so they all leave on the 500th night.

Dear Pledges,

Congrats on making it this far! While the process is stressful and difficult, I wish all you the best of luck in completing the pledge process. As a reminder, certain signatures are needed in order to be initiated and I would like to provide some signature opportunities for those who do not have my signature (VP Admin):

Task #1:

Remember that email I sent out about pranking Brother David Martorana? Well that actually was a legitimate pledge task and it is still up for grabs. Pledges who are interested in pranking David M. may email me privately, and depending on the prank, will receive my signature, and very likely, the signatures of other brothers.

Task #2:

Scale and Coin is currently looking for a talented website designer to create the Scale and Coin website. The first two (2) pledges who volunteer to create this website will receive my signature, and very likely, the signatures of other brothers.

Task #3:

The first two (2) pledges who volunteer to create a Harlem Shake video of their pledge class and/or Scale and Coin Brothers will receive my signature, and very likely, the signatures of other brothers. The video should be at least 45 seconds long and be as ridiculous as possible.

Let me know if any of you have questions about the pledge process and/or about my tasks. Good luck!

Best,

My name is Maggie Lawson, and I am very enthusiastic to join the Internet of Think study program at STIKOM University. I am very interested in the world of technology and how software can help solve real world problems.

Since young, I have had a passion for programming. I started learning my first programming language at the age of 18, and since then, I have never stopped learning and developing my skills. I've worked on several small projects and worked on several applications Slot Demo Indonesia, which helped me understand the software development process from start to finish.

I am very interested in learning concepts like web development, mobile app development and database management. I also believe that collaboration is the key to creating great software, and I am passionate about working in teams to tackle complex challenges.

While at university, I hope to deepen my understanding of various programming languages, software development methodologies, and also understand how to solve problems in software development effectively. In addition, I plan to engage in group projects and practicums to gain deeper practical experience.

Outside of academia, I enjoy exploring side projects, learning about the latest trends in the tech industry, and participating in developer communities. I also believe that continuous learning is the key to staying relevant in the rapidly changing world of technology.

I really enjoyed meeting my classmates, lecturers and professionals in the software industry. Let's explore this exciting world together and collaborate to create innovative solutions.
