I would like more users to register my side project ( http://getmousetrack.com ), but I can't seem to convert anyone who visits the project site. At this point, I think I would pay for some service that gives me honest feedback on my landing page and maybe suggest ways to improve conversion rates.

Create a tagline. I should be able to figure out what I'm looking at in 5 seconds, not ~40 seconds.

Here you go :) http://balancedpayments.com

Thanks for the link! I didn't specify that it would have to work outside of the US, which is my mistake. That said, I had no idea this existed and it's definitely on my radar now. Thank you again.

Have you thought about forming a US corporation (C Corp or LLC)? Yes, you would have to pay some taxes, but you could choose a low/ no tax burden state like Delaware or Wyoming.

Assign a local agent, with physical/ mailing address, and open a US business banking account is pretty much all there is to it (not all). I've actually considered offering this as a service, but convincing myself there is an actual need has been difficult.

If you can reduce the act of registering a Delaware C Corp and opening a US bank account to entering my billing details, you'll have my business.

Probably not worth solving, certainly not something I would solve myself but... I'm up late all the time working. True nightowl you could say. The earliest I'd go to bed is 6am. I sleep during the day and wake up around noon at the latest. I don't lack sleep, this schedule works for me. Point is, I'm up late and I'm sure there are others like me. I get hungry often. I don't cook. Few places if any are open. Those tha…

Given how few places are open at, say, 1am, Yelp tends to work fine. Just use the 'open now' filter

It does not. I even specifically mentioned this in my OP. Yelp filters are busted because most of the hours posted on many establishments on Yelp are off basis in my experience. Some lack hours altogether.

I work on numerical simulations, where I deal with colossal arrays of floating point numbers on hundreds or thousands of nodes. I want tools that can help with the following:

1. Visualizing code. Rendering C++ and/or Fortran as LaTeX would be very helpful for lines of code like this, where I've spent too much time tracking down misplaced parens:

    k1(1,1)=-Im*(Omega_minus_n*(rho13(i,j)+conjg(rho12(i,j)))-Omega_plus_n*(rho12(i,j)+conjg(rho13(i,j))))+gamma1*(rho22(i,j)+rho33(i,j))
2. A better way to debug and test mathematical programs. Debugging is extremely hard when you have thousands of processes doing calculations that aren't reproducible by hand, so it's very difficult or impossible to create test cases for subunits of the program. The only tests are Fermi calculations and comparison of the whole program's output with an analytical solution, which is often not possible, and is not useful for debugging.

3. A language with the following characteristics: - Within 10% of Intel/PGI Fortran on tight numerical loops - Array and distributed/concurrent syntax with lightweight threads and syntactical support for GASnet/MPI. - Parallel load balancing, preferably across nodes. A few of the algorithms I use are adaptive or have parts of the solution domain that require much more work than other parts, leading to situations where naive/maintainable MPI code leaves most processors idle. - Hindley-Milner type inference, typeclasses/typeclass-like features, operator overloading/syntax extension, and effortless interoperation with C/Fortran. An IDE with syntax rendering like Maple or Mathematica's would be a HUGE plus. I don't know why this doesn't exist for usably fast languages. - Supports an interactive mode with easy visualization

The closest language I've seen is Cray's Chapel, but there are several things I don't like about it. Its imperative/oo design and lack of first class functions/tco are unacceptable, since the algorithms I use need to use the integer side of the machine as well as the floating point ones. Right now I use either Charm++ (http://charm.cs.uiuc.edu/) with Intel's array syntax, or Fortran 2008 for some inherited code. C++ has non-ideal semantics for numerical code, and doing non-trivial algorithms in Fortran is still a nightmare, especially when using MPI, as communication code quickly becomes the main part of the program. Something like Sisal (http://sourceforge.net/projects/sisal/), if it was modernized and extended to distributed architectures, would be amazing. It used to beat typical Fortran by 20%.

4. I absolutely need to account for cache behavior, otherwise my simulations will take months to run instead of weeks. I would love anyone who wrote a practical tool that automatically tiled loops, since doing this manually turns code into an unmaintainable rat's nest very quickly, or wrote a library of skeletons for tiled loops and cache oblivious algorithms.

1. I want to finish my CS bachelors degree online from somewhere reputable

2. I want an "Uber for babysitters" (yes I know of sitter city and the like, not impressed) ... we are very last-minute and spontaneous so our regular sitters aren't always available.

3. I often want to try making new/different cocktails but I never have all the ingredients ... ("birchbox for cocktails"?)

4. I have a close female family member that is overweight/obese and on a trajectory to get worse. No one else in the family knows how to help or even approach the subject.

In regards to 1: Any decent editor should have highlighted parens matching. What do you use for coding?

Sorry, missed that part.

Out of curiosity, where do you live? AFAIK, Yelp's hours are user-submitted, so you might just be in a place with low yelp usage.

I reside in their home city (SF), and I've rarely ever had issues with faulty hours. In your case, you might just need to hire someone to collect the data, since individually no one has enough incentive to do so.

The focus on finding problems to fix is a bit shortsighted. Focus on building what is missing . Somehow, hackers seem to forget this important detail. A problem that is fixed is no longer a problem. But building something that was missing is now a tool used my many. Facebook does not fix a problem. It built something that was missing (a good social network). Google did not fix the search problem. Is built something t…

Anything that is missing can be re-phrased as a problem to fix.

e.g. It's really hard to keep up with what's going on in all my friends' lives It's hard to find stuff on the Internet if I don't know who hosts that information Hotels are too expensive for medium-length stays

I'd love to have an easier way to get involved in some open source project for improving my skills, enhancing my CV, etc. My main challenge is being overwhelmed with information and I can't seem to find a good place to get started on any project.

I remember someone saying, "if you don't know where to start, search for '//TODO:' on Github." :)

Do you have any sources that elaborate? I've actually spent several hours trying to figure out how to contribute to open source, and given up out of frustration.
