Solo business, Schedule C question

As I consultant, when I travel on client business, I pay for travel with a card and the client reimburses me (on top of my fee). Likewise with other expenses -- I buy a projector for use on a project, client keeps projector and reimburses me as above. So do I include such reimbursement amounts in both my income and expenses on Schedule C?

Teach me to robot.

I have an Arduino, and I want to make it do things. I gather that what I really want is a Raspberry Pi in addition to my Arduino. The trouble is, I don't know Python and my C and circuitry skills are severely rusty. So do you know of any online courses or physical books that will teach me all of this as a general subject of "making devices" rather than individual Python, C, and electrical engineering courses of study?

Why won't this code open a file for output?

I'm learning C++ and I have this code that's supposed to ask a user for the name of a file to read from, then perform some editing of what it read, and then write the result to another file, the name of which was also provided by the user. The code opens and reads and performs the edits just fine, but reports that it cannot open the file for output. Out put to the screen works fine with cin >>. [more inside]

My kid stumped me with a question about the speed of light

On a car trip yesterday my kid posed a hypothetical question. I was blown away, and I have no idea how to answer it. This is what she said. "So light takes 90 minutes to go from Saturn to Earth. What if, instead of shining a light on Saturn, you had a long metal chain that stretched from Saturn to Earth. A person on Saturn pulls on the chain. How long would it take the person on Earth to feel that pull?" [more inside]

Acid/Vitamin C and ADD Meds

For someone who takes Adderall for ADD, will drinking acidic drinks (including say juice, soda, or homemade drink with apple cider vinegar) and/or taking vitamin C supplements mute or dull or interfere with the medication? Talking to pharmacist and googling has yielded some very mixed and confusing answers, and I'd love it if somebody knew enough to give a definitive answer.

Why does this work in a Windows Forms solution but not a as Class Library?

I have a driver written in C++; it's set up as a solution within a VS 2008 project. If I go and create a new "Windows Forms" solution and reference the driver, it works fine (Intellisence works, it compiles etc). But when I try to do the same exact thing with a "Class Library" solution it will not see,link, whatever anything in the driver. I know I'm light on information, but its that simple "Class Libary"->Fail Winforms-> "No Fail"! I can't seem to come up with any good google searches for this either. Please help me hive mind!

What does it mean when someone flashes you a "C" while driving?

Tonight around midnight, in South City St. Louis, MO, my mom pulled up to a stoplight left of a pickup truck, and the thirty-something, white, crew-cut haired driver flashed her a hand sign that looked, from her perspective, like the letter "C." He did this several times over the next couple minutes whenever he pulled along side her, until she managed to lose him. Has anyone seen this before or know what it means?
