    Editing Protected Sheets Through Google Apps Scripting

    Does anybody know of a way that I can protect a Google Sheet in such a way that it can only be edited via scripts? Ultimately I'm putting something together that acts as a very poor man's ticketing system. I have information displayed in a sheet and a set of buttons with scripts attached to...

    Fluid Dynamics 2 Tynea: Unsolvable Pipe Network Problem?

    Are you taking into account that each of the junctures are at different elevations? It makes the drawing a little easier to visualize. As far as lazy professors, if this prof isn't a brand new one, he's probably assigned this before. That would imply that it has a solution. My Statics and...

    First Crack at Multithreaded Programming

    Homework Statement Create a multithreaded program (Java) that finds a word in a text file and reports the lines one which the word appeared. Word lines should be reported in the order in which they appear. Homework Equations The Attempt at a Solution I know that I can just...

    DSP Software for Communication Systems

    Homework Statement DSP Technology Report Research a particular application of DSP, gathering enough information to deliver a 10 min oral report to the rest of the class. You can focus on hardware, software issues, or a specific algorithm. Give as much detail as possible. Homework Equations...

    Comp Sci Java Non-Recursive du command popping java.lang.InterruptedException

    By what I gather my error was coming from something wacky with the JFileChooser. On my Windows machines it would pop whenever I chose the default directory brought up by the GUI. As for the null pointers, I just haven't gotten to the point where I was worried about dealing with protected...

    Comp Sci Java Non-Recursive du command popping java.lang.InterruptedException

    Homework Statement You are to write a robust program (i.e., a public static void main()) that accepts a file pathname (e.g. 'c:\foo\bar' or '/home/jblow/' under UNIX) as input and then calculates and prints the size of that filesystem object: java FileSize c:\foo\bar 123625 bytes The purpose...

    Conductance per unit length of a co-axial cable (Intro to Electromagnetics)

    Thank you so much for that. I feel ridiculous for not just drawing a picture. It's funny how PHYS212 gets overshadowed by ENGE360.

    Conductance per unit length of a co-axial cable (Intro to Electromagnetics)

    For the surface integral I did this: -\sigma\int_{0}^{2\pi}\int_{a}^{b}\frac{\rho_{l}}{2\pi\epsilon_0r}drd\phi=-\sigma\int_{a}^{b}\frac{2\pi\rho_l}{2\pi\epsilon_0r}dr=\frac{-\sigma\rho_l}{\epsilon_0}ln(\frac{b}{a}) For the line integral I did this...

    Conductance per unit length of a co-axial cable (Intro to Electromagnetics)

    Homework Statement Starting with: G = \frac{I}{V}= \frac{-\int_{s}\sigma\mathbf{E}\cdot d\boldsymbol{s}}{-\int_{l}\boldsymbol{E}\cdot d\boldsymbol{l}} Derive the conductance per unit length, G', of a coaxial cable by assuming a line charge of \rho_{l} on the center conductor...

    How can using color in note-taking improve memory retention?

    I've recently faced a very similar predicament. I have the bad luck to have very regular migraines. This means that at least one or two days out of every month, I'm missing a series of classes. I'm currently heading into my fifth year of EE and it's only becoming more taxing on me. It isn't...
