  • week 05 : 02 oct - 06 oct : lab!
    1. we did homework 1 related stuff.
    2. HW tip: in order for your homework files to be accessible, you should give permissions (755) to all the parent directories of each file, including your home account. this means that all directories involved in this path: your_login/public_html/hws/hw1 should be set to 755; the same holds for all the underlying files and directories of the actual homework. You can do that with: chmod -R 755 ~/public_html

     

  • week 04 : 25 sep - 29 sep : lab!
    1. we made an introduction to adobe photoshop
    2. we learned about layers (tutorial1 - example)
    3. we made a picture fade in the background (tutorial2 - example)
    4. we created a glowing version of our names(tutorial3 - example)

     

  • week 03 : 18 sep - 22 sep : lab!
    1. we all have our accounts by now (and we know our passwords)
    2. we all have ran the "web-ok" command. please check that a public_html directory has been created under your home (login) account before you come to the next lab. if not repeat the procedure!
    3. in the lab we talked about the unix filesystem hierarchy. we also visited various directories using cd and ls and we always knew which our working directory was by typing pwd.
    4. we talked about relative and absolute paths.
    5. we created new directories using mkdir. When we made a mistake we deleted directories using rmdir.
    6. we set the permissions to our home directory in "drwxr-xr-x" mode. we did that by typing:
        • cd (return) // (get to my home directory)
        • cd ..(return) // (get to the cs101__ directory)
        • chmod 755 login // (your login-name)
    7. we found out how chmod works and how to calculate the number that defines the permissions.
    8. note that whenever you are asked to have your homework somewhere by someday, you should:
        • give permissions (755) to all the directories above it
        • give permissions (755) to the actual file of the homework

         

  • week 02 : 11 sep - 15 sep : lab!
    1. we set our accounts (csa & nt). it is recommended to use the same password for both
    2. we opened the SSH (Secure Shell Client). you can also use that from home and practice on your unix skills. download it here. remember, host: csa.bu.edu
    3. we ran the "web-ok" command. we typed "agree" and our csa password and we did not get the "invalid password" message. if you don't see a "public_html" directory under your home directory it means that something went wrong and you have to repeat the process again asap
    4. we ran basic commands ls and cd (unix tut. - unix pres.)
    5. we found out that our "unix home directory" can be visited via "mycomputer/Z:". note that "Secure File Transfer Client" (included in ssh) provides you with similar functionality as the z-drive
    6. we used dreamweaver to make our first webpage. we created a table, we copied images from google images, and we set various background colors in each table cell. our first page looks something like this
    7. we found out that until we have our own public_html directory we cannot publish our pages on the web
    8. we used "pico", the editor, to create another html file. this time we typed html code directly instead of using a graphical interface such as dreamweaver (html tutorial). (tip: you can always create a notepad file in your pc and type in html, save it as "mywebpage.html" and then open it with a browser)
    9. don't forget to ask someone to send you a google-invitation!
