Remote working questions
Your first point of contact should be your
you can then drag (or paste) these pictures into a word document.
Homework grades are available on websubmit.
Your first point of contact should be your teaching fellow,
who is empowered to review and re-grade homeworks.
The most effective strategy is active recall. Reading the book, notes and examples alone will give you a false sense of familiarity. Instead, you must actively digest the class material, and practice your recall of it in question and answer form.
After each class meeting, review the class notes and examples, and especially points that I spend time elaborating upon. For each of these "main points" -- there are probably about 4-6 of these per class meeting -- you should write out a challenging question about the point, and prepare the answer.
By actively preparing questions that you know you can answer, you will be surprised how many of those show up on the quiz/exam.
If you had an authentication problem (e.g. login screen did not accept username/password), then it is an issue with your university username/id -- and it might get fixed by just closing and restarting the browser.
If the problem was either that you never made it to the authentication screen, or else that you authenticated and then had an error, please let me know more specifically what happened -- maybe by taking a screenshot of it and emailing it to me.
There is a file-size limit for submissions -- 500KB.
The most likely cause of this is that your file is too big, and this generally happens
because your screen shots are huge (too high a resolution). Think about the number of pixels...
Try editing your screen shot (e.g. in Microsoft Paint or ColorSync Utility on mac) to
reduce its quality/number of pixels/size.
Just resubmit your file. Websubmit always keeps the latest copy (and archives the older versions), so you can submit many times, and we'll grade that latest submission only.
You can use FTP (file transfer protocol) to access your home directory. You'll need a secure version of FTP to connect to csa.bu.edu or csa2.bu.edu.
Running winscp is a bit like putty, you enter a host (csa or csa2) and use your account to log in.
It's also possible to mount your home directory as Z drive on your laptop, but it requires additional setup and I don't know how to do it. If you're interested, please ask the tech people at the computing lab.
You should download a program called Fetch, which is a File Transfer Protocol client. Go to the http://fetchsoftworks.com/ website, and "buy" the free academic license.
To connect to the "Z:/" drive, open Fetch and connect to the hostname
You need to use the CS UNIX account password you created at the CS lab, and not your regular BU Kerberos password that you use for everything else. If you do not remember the password, you can go to the lab staff and ask them to reset it for you.
