I don't know if anybody else suffers from this but every now an then I get homework requests. Here is one form today which may make you all laugh and cheer you up after a long week. PS I NEVER DO PEOPLES HOMEWORK FOR THEM! I wish there was some way to filter who is allowed to use your FEX email. I have removed the offenders contact details so as not to completely humiliate them.

Dear Nick,
 
I saw your FDTD file on mathworks.I have a matlab assignment due on sunday and i am completely lost.Please help me otherwise i will fail the course.I will really appreciate your help.I know you might be thinking who i am and why should you help but i will pay $ 200 if you can help.
I am really sorry if any of this makes you mad.I am a person who is looking for help.here is the assignment
i am sure it is easy for you
 
Project: 2D FDTD in MATLAB!
! " Write a 2D FDTD program in MATLAB that solves Maxwell’s equations for an “interesting”
problem. Examples could include the following. If you want to do another, ask.!
! " 2D photonic crystal, i.e. an array of dielectric or metallic cylinders!
! " PEC slab waveguide and coupling efficiency and a “step” problem with reflection !
! " Dielectric slab waveguide, plot the confinement of the field, insert “step” with reflection!
! " Resonant frequency of circular/square metallic nanoparticles!
! " PEC resonant cavity with a nanoparticle perturbation, and how do the cavity modes change!
! " Measure the far-field diffraction from subwavelength slit apertures in a PEC, compare to
standard diffraction theory!
! " The problem should provide some measurements, such as coupling efficiency into a
waveguide, the resonant mode of a system (excite with a pulse, sample the field and do FFT,
or simulate many times at different wavelengths), etc…!
! " The problem could take advantage of various boundary conditions (periodic, symmetric, anti
-symmetric, or absorbing if you are ambitious), or just make the simulation region large
enough!
! " You should incorporate the Drude model, or your problem must include some more complex
multi-dielectric structure !
! " You could use the other polarization (TE) if you want to study the H field from, say, an
arrangement of metallic wires!
! " Refer to the papers cited here, especially Yee’s original paper, if you have problems

Wow. This is just sad. I also get a few requests, but
never this bad. How could they offer you so little
money? I would suggest charging at least twice that
much. ;-)

Hahaha, we almost need a Matlab eBay for these requests. Start the bidding high and go lower in price until you find someone who will do it for the lowest price. This person really has their work cut out for them over today and tomorrow.

Quoting from my response to the latest person to the latest person asking me
for complete source for their senior project or something similar:

   Are you offering to pay me my consulting rates to attempt to locate
   such software for you? If so, then please be aware that my minimum
   consulting fee for any MS Windows related matter is $C50,000 (fifty
   thousand Canadian dollars) -- a fee which basically just covers my
   listening to the question seriously and does not cover any of the
   work involved.

The wording I use is a bit more polite if they email me at my work account, but
I interpret nuisance requests sent to my work account as requests to hire the
organization I work for for some Fee For Service work... and my organization's minimum
Fee For Service fee with people we don't know is pretty much $C50,000.

I was recently asked by a company in India to write a Matlab code (A GUI no less!) that solved the inverse problem for resonant frequencies of anisotropic, inhomogeneous samples in complex geometry. They needed it "urgently" (5 days if I remember) and of course, "would appreciate" my "help." After a tortuous, lengthy deliberation (only slightly longer than: tic,toc), I declined.

I'm surprised they didn't also ask you to figure out the secret of immortality! I guess that would have taken an extra day. =)

I found one of my own students here (years ago) trying to get a free ride with one of my computer assignments in a basic signals and systems class. If I remember correctly, I posted a reply in the form of my office room number and office hours.

Guess what, the dude never showed up ;-)

Sorry to hear you are part of this crowd. I can barely count how many
requests I get, possibly because of my blog and interactions here. Too
bad others are being swamped as well.

Yes, having a popular blog will do that! Mine is not that big and we get a bunch of ludicrous requests as well.

Some actually do pay, even if you offer them the project for free. I would know, I bought a PS3 and several games thanks to the FEX. Also, a number of requests are from educated people who simply do not have the time to program. It is very easy for me to picture myself being the one asking the questions instead of the one doing the work.
