Hello everyone! Welcome back! This is cs50! How’s the C$50 Finance? It was fun, right? Hehe..Umm.. well, today I’m going to write about Problem Set 8. OMG, the last!!! OK, so what it is all about? It is all about JavaScript and third-party APIs.
As always, take your time to read :https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide
Why is the cs50.h file not being found? Is the file being installed correctly? I searched for similar questions but others seemed to be experiencing a slightly different problem: Harvard CS50 Library, Need Help Installing on Mac OS X. Adding a header file to Xcode. Cs50 library wont link to file in cs50 appliance. I’m taking this course from cs50.tv, which is Harvard extension school and in the course they are using a library they made called cs50, on this link its available for download https://manual.cs.Getting Started
Per the instruction http://cdn.cs50.net/2014/x/psets/8/pset8/pset8.html, if you don’t have Chrome installed on your computer (not inside of the appliance), download and install the latest version of Chrome from http://www.google.com/chrome.Then using Chrome, download and install the Google Earth Plug-in from http://www.google.com/earth/explore/products/plugin.html. Note that the plug-in requires Mac OS or Windows unfortunately. Once the plug-in installed, you may need to reload that page or restart your browser, but you should see a 3D Earth embedded the page. If unable to get Google-Earth plug-in, you may skip this problem set.Best to minimize the number of programs and windows you have open while working on this problem set. The Google Earth Plug-in likes to consume CPU cycles and RAM. In fact, if you ever feel your computer slowing down, you might want to quit some programs or even reboot (after saving your work).Next, start up your appliance, open a terminal window and execute :
To ensure that your appliance is up-to-date!Like Problem Set 7, this problem set comes with some distribution code that you’ll need to download before getting started. Go ahead and execute :
Then execute :
In order to download zip file of this problem set’s distro. Then execute :
You should see that you now have a file called pset8.zip in your ~/vhosts/localhost/public directory. Unzip it by execute :
Then :
You should see that you now also have a directory called pset8. You’re now welcome to delete the ZIP file with the below :
If you next execute :
Followed by
You should see that pset8 contains index.html and four directories (css, fonts, and img, and js). Ensure that all files inside of the pset8 (and its descendants) are world readable by executing :
So that the appliance’s web server will be able to access your work. Then ensure that all directories inside pset8 are world-executable by executing the below :
Finally, ensure that few other directories are still world-executable by executing the below :
If you opt to create files or any other directories for this problem set, keep in mind that :• any files should probably be readable and writable by you but only readable by anyone else (i.e 644).• and any directories should world-executable (i.e 711).
Unlike Problem Set 7, your code for Problem Set 8 will indeed live in a virtual host (aka vhosts) called localhost rather than one called, e.g., pset8. Using localhost will make it easier to access your code from Chrome on your own computer (outside of the appliance).
Now head to the URL below using a browser on your own computer (outside of the CS50 Appliance), where w.x.y.z is your appliance’s IP address (which should be displayed in the appliance’s bottom-right corner), and each of w, x, y, and z is thus a number between 0 and 255:
You should see University Hall! If not, do double-check that you’ve not missed or mistyped a step.
Incidentally, anytime you’d like to print some debugging information to the Console tab of Chrome’s Debugging Tools during this problem set, a la printf in C, know that you can include a line like
in your JavaScript code. So long as Chrome’s Console is open, you’ll see that text. Just be sure to remove any such lines before submitting your work. Do keep an eye on that Console during development, too, as syntax errors and more tend to appear there in red. Alternatively, you can include a line like
in your JavaScript code to display messages to yourself, but the pop-up that results tends to be more annoying, especially if you accidentally call alert in a loop!
Your mission of this problem set is to implement your own shuttle service that picks up passengers all over campus and drops them off at their houses. Your shuttle equipped with an engine, a steering wheel, and some seats. Assuming that you’re still at http://w.x.y.z/pset8 looking at University Hall, here’s how to drive the keyboard:
Oops! Where did I go? I think I’ve lost my way…
