 Now that you're able to create and run a Dart application
 and have a basic understanding of DOM programming,
 you are ready to leverage code written by other programmers.
 Many interesting and useful packages of reusable Dart code
 are available at the
-<a href="http://pub.dartlang.org/">pub.dartlang.org</a>
+<a href="https://pub.dartlang.org/">pub.dartlang.org</a>
 repository.
 
 This target shows you how to use `pub`&mdash;a package manager
 that comes with Dart&mdash;to
 install one of the packages in the repository,
 the vector_math package.
 You can follow these same steps to install any package hosted at
-<a href="http://pub.dartlang.org/">pub.dartlang.org</a>;
+<a href="https://pub.dartlang.org/">pub.dartlang.org</a>;
 just change the package name when you get to that step.
 This target also describes some of the resources you can expect to find
 in a well-built package.

 ##About the pubspec.yaml file {#about-pubspec}
 
 To use an external package,
 your application must itself be a package.
 Any application with a valid pubspec.yaml file in its top-level directory
 is a package and can therefore use external packages.
 When you create an application using Dart Editor,
 Dart Editor automatically creates a `pubspec.yaml` file.
 
 Start Dart Editor and create a new application with the name `vector_victor`.
 Double click pubspec.yaml to view its contents.
 
 ![Dart Editor with pubspec.yaml file](images/victor-files.png)
 
 The pubspec.yaml file contains the package specification written in YAML
-(visit <a href="http://pub.dartlang.org/doc/pubspec.html">Pubspec Format</a>
+(visit <a href="https://pub.dartlang.org/doc/pubspec.html">Pubspec Format</a>
 for in-depth coverage).
 Dart Editor provides a user interface for editing the pubspec.yaml file
 so that you don't have to worry about the YAML format.
 Or you can click the **Source** tab at the bottom of the Editor pane
 to edit the YAML code directly.
 Below is the pubspec.yaml file that was
 created for the vector_victor application.

 Dart Editor adds the package name to the list.
 
 ![The application is now dependent on vector_math](images/after-add.png)
 
 Notice the **Version** field.
 `any` means that this application can use
 any version of the vector_math package.
 You could instead specify a particular version of the package.
 When versioning becomes important to your project,
 check out

-<a href="http://pub.dartlang.org/">pub.dartlang.org</a>
+<a href="https://pub.dartlang.org/">pub.dartlang.org</a>
 is the primary public repository for Dart packages.
 `pub` automatically checks that
 website when resolving package dependencies.
 To use one of the packages from that site,
 you can specify it by its simple name,
 as we have done here.
 
 ##Install the package dependencies {#install-dependencies}
 
 In Dart Editor, save pubspec.yaml with **File > Save**.
 When you save the file,
 Dart Editor automatically runs
-<a href="http://pub.dartlang.org/doc/pub-install.html">pub install</a>,
+<a href="https://pub.dartlang.org/doc/pub-install.html">pub install</a>,
 which recursively installs the Dart libraries
 from the packages in the dependencies list.
 You can also select **Pub Install** from the **Tools** menu in Dart Editor.
 
 Pub puts the libraries in a directory called packages
 under the application's top-level directory.
 Click the wee arrow to expand the packages directory.
 There you will find the vector_math directory,
 which links to the Dart libraries from the vector_math package.

 the vector_math package has other resources that might be useful to you
 that do not get installed into your application directory.
 Let's take a step back for a moment to look at what
 you got and where it came from.

Why this change? I think it's GitHub, located at github.com.

(Just confirmed by visiting the site.)

cuz I use github in a thousand other places! ;-)
