Review from previous weeks

Human factors

Add to list:

Class web server

The class web server is located here:

The example home page is located here:

Your student home page will be located like this:

Class web server credentials

You will need FTP credentials:

  • Host
  • Username
  • Password
  • Subfolder

Instructor will provide these credentials.

Secure your credentials:

  • Keep secret
  • Do not share
  • Be respectful other students and instructor, this is a shared FTP account

File Transfer Protocol (FTP)

File Transfer Protocol (or simply FTP) is a widely-used protocol for transferring files across computer networks.

FTP consists of two programs:

The FTP server has two tasks:

  • Receive uploaded files from clients
  • Send downloaded files to clients

FTP servers are typically associated with web servers. If you have a web server account, you probably have an FTP account to go with it.

The FTP client has two tasks:

  • Upload files to server
  • Download files from server

In this course, we will use FTP clients to upload and download files.

  • We will not download, install, or work directly with FTP servers

FTP clients

Many FTP clients are available. All do essentially the same thing.

For this class, You may use any FTP client you like.

FileZilla

FileZilla is a popular FTP client:

  • Free and open source
  • Available for Mac, Windows, Linux

FileZilla uses a two-panel display:

  • Local files (on your computer)
  • Remote files (on web server)

Fetch

Fetch is available for Mac only.

  • Fetch uses a single window to display remote (web server) files
  • Use a Mac Finder window to display local (your computer) files

Using FTP clients

You will need:

  • An FTP client
  • FTP credentials
  • Log in using your FTP credentials
  • Upload files (transfer from local to remote)
  • Download files (transfer from remote to local)
  • Close your FTP program

Document with screenshots:

Limited FTP connections

We have limited FTP connections.

Please do your part to share the limited number of FTP connections:

  • Run your FTP client when you need it to download or upload files
  • Close your FTP client as soon as you have finished your tasks

How many is this "limited number" -- ?

It could be as few as three or four total FTP connections in the classroom.

That's not entirely clear. The numbers vary from class session to class session. And the numbers may be different inside the classroom, as opposed to outside.

In any case, we have limited resources -- please use them courteously.

Digital images

See:

HTML img element

See HTML img element.

Background images

See Background image (web design).

Graphics software

See:

Responsive images

Responsive images resize to fit different circumstances.

This is done with media queries.

Responsive images in Bootstrap

In Bootstrap, you make an image responsive by adding the img-responsive class: 

<img src="image.jpg" alt="example" class="img-responsive" />

The image will expand to fit the available space, up to the full image size.

See Bootstrap responsive image.
