I have a hp deskjet 3920. Today when I wanted a printout what my printer gave was a readable printout but with all the vertical lines being discontinuous. My black (21) cartridge was almost empty and I tried inserting a new one. But the problem persists. Can you help me to figure out what is wrong with my printer please?

There was a chat between me and an unknown person on Y! chat long time ago. It was just few lines although. Today when I logged on to FB, here it shows me that person's name under "People You May Know". FB has been continuously asking me to provide access to my email account saying "Friend Finder" or something like that. But I've never accepted it because I don't want to connect with my Y! contacts on FB. I suspect Facebook have unauthorizedly accessed my contacts in my Y! account. What is going on?

I'm 100% sure we don't have friends in common. Maybe its just coincident?

1. Quantum mechanics

2. General Throey of Relativity

Which of the above is harder to understand? (presumably at undergraduate level)

Your answer may reflect the nature of philosophy behind the subject, mathematics involved, etc

I remember once someone told me that "probable" and "being possible" are to entirely different things.

Can you please explain this statement to me?

What makes "Probability = 0" different from "Impossible"?

I frequently download large amounts of data. Is it ok to keep my macbook pro switched on overnights?

Let ψ₁, ψ₂, ... , ψᵥ be an orthonormal basis set.

And,

ψ = c₁ψ₁ + c₂ψ₂ + ... + cᵥψᵥ

It is given in the lecture note I am provided with that since 〈ψᵤ|ψᵥ〉 = δᵤᵥ we can find

cᵣ = 〈ψᵣ|ψ〉

The proof is given and I understand that. The problem is, how can one apply this to find cᵣ without really knowing c₁, c₂, ..., cᵣ, ..., cᵥ? (ψ = c₁ψ₁ + c₂ψ₂ + ... + cᵥψᵥ)

Tell me something interesting about starting to get lot of thumbs-downs only after being honest and stop defending an incorrect answer...

Due to its polarized a bound volume charge density can be obtained for the region inside the dielectric. Is laplace's equation still applicable to the region inside the dielectric?

Their previous layout was great and revolutionary. But they don't even provide an option to stay with the previous layout for people who dislike new ugly mess. Yes its true that they provide their service for free, but is it ethical for a recognized company to do this forcibly? :(

I have to complete a stat take-home assignment for which any of Minitab and SPSS is permitted.

But there is a question in the assignment that I have to conduct a hypothesis test based on a sample~Bin(n,p), in which only n and p but no actual data are given.

Even though in Minitab there is an option to input the parameters and proceed the test without having to specify the actual data I am unable to find a solution in SPSS.

But I love the output of SPSS which is easy to interpret and understand.

Please help me to solve my problem

(I use Minitab 15 and SPSS 17)

I'm a new comer to irc network. Today I tried to chat with someone through irc. But nobody replied me, maybe because they don't know me. In one IRC network (I don't remember the exact name) there was a room named 'rosaporn'. In search of any friend, I joined it. But there was only one person. She said that she is 14 years old and she is from london. And she asked me to upload my photo. She asked me to take the photo without wearing a shirt. After that the chat went to a different side. But suddenly she replied 'Federal Bureau of Investigation has monitored this chat. [rascalflatz] You will be arrested under ....". Rascalflatz was my nick name. And then she asked 'Are you online still? Im asking this for your own safe'. I replied 'Yes. But what is this? Is it true?' Then she replied 'Yes. Eat s#!t ni99er!". I want to know is this only a fake or not. Please help me! Can people see my IP through IRC? Oh god! Will I be arrested?

I use a free file sharing. It limits the download jobs I can carry out to only 5 downloads per day. But I think this is fairly unreasonable. Most of the files I download are smaller files (between 10 to 200 kB). But some of my known friends download large files from that same site and so they download more than 500MB a day though I can download 50kB to 1MB . Is there an easy way to spoof my MAC address? (I use a router and an ADSL link)
