Other Services

Other services offered to the Math Dept personnel:

• private or shared repositories (no anonymous access) using git, mercurial (hg), or svn
• cloud storage, file sharing, backup tools using Cloud Station at https://cloud.math.cmu.edu
• 3D printing
• survey tools using LimeSurvey: create surveys at https://survey.math.cmu.edu/admin/ (LDAP authentication) and ask the audience to respond using https://survey.math.cmu.edu/

To access any of these services as a new user, please use the credentials from one of the available Math/Physics Clusters with a valid working account. If they don't work, please go to https://account.mcs.cmu.edu/ and follow the forms to create a password for yourself by using either your andrew credentials, or by resetting the password from one of the available Math/Physics Clusters with a valid working account. This is a one time process that will extend the validity of the cluster password to all the new services, but will not affect the andrew password.

For external collaborators (no andrew login), please generate an invitation to create sponsored guest accounts through https://account.mcs.cmu.edu/andrew/ -> Generate Registration Link. Such accounts give them access to all the services described on this page.

Project repositories

Most projects need a file versioning mechanism keeping a history of its development, allowing shared access, branching., and merging the changes from different collaborators. Through services like github, free repositories have significant limitations (e.g. public read access). Our server at https://git.mcs.cmu.edu/ offers a variety of repositories (git, svn, hg) and sharing options, while keeping full control over all the features. Repositories are restricted only to subsets of users of our server. For anonymous access please use one of the existing public services (e.g. github) as a second origin.

For easy ssh access, please configure the repository account with your SSH key:
My Account -> SSH Keys -> add description and content of ~/.ssh/id_rsa.pub
Then create an empty repository of your choice, and populate it with your project by using the following setup:

GIT:

git clone ssh://rcode@git.mcs.cmu.edu/Repository_Name
then push/pull the contents.

SVN:

svn checkout svn+ssh://rcode@git.mcs.cmu.edu/Repository_Name Local_Directory
cd Local_Directory ; svn add files/dirs ; svn commit

If the repository was allocated to a specific group of repositories in the web interface, that should be included in the URL. E.g. the new URL for GIT becomes: ssh://rcode@git.mcs.cmu.edu/Group_of_Repositories/Repository_Name

Cloud storage

The Math Dept offers infrastructure for:

• On-site large capacity cloud storage;
• File sharing through web link;
• Photo backup and organizing using the "Synology Photos" apps for mobile devices (Android, IOS) distributed in the App Stores;
• Backup/sync of public cloud volumes (like Dropbox or Google Drive) using the "Cloud Sync" application in the account.

All these services can be accessed via a web interface at https://cloud2.math.cmu.edu/ or via clients available for Windows/Linux/MacOS and Android or IOS mobile platforms. The cloud software is called "Synology Drive" and was made available by Synology Inc.

Cloud Station client setup

Get the client:

Login to https://cloud2.math.cmu.edu/ using the Math login and password -> Menu -> Synology Drive -> Get dektop and mobile apps now (lower right corner of the new window) -> download and install Synology Drive (for desktops/laptops or mobile) -> Install the client by the proper procedure using the OS package manager
(e.g. for Ubuntu: "sudo dpkg -i synology-drive-client-????.x86_64.deb")

Desktop configuration Linux (Win, Mac similar):

Start the client:
For Ubuntu "synology-drive"
Domain Name: cloud2.math.cmu.edu
User name/password: credentials on cloud2.math.cmu.edu
Enable SSL: check
CloudStation dir: /home/Drive
Local dir (by default): ~/SynologyDrive
Decline to switch to QuickConnect if prompted.

Mobile app configuration:

New connection (https on): cloud2.math.cmu.edu
Login with Math credentials;
Allow requested permissions.

How to share some of your files with other users

1. Login to https://cloud2.math.cmu.edu
2. File Station -> CloudStation -> identify files to be shared
3. Right click -> share -> set password for file or share with local users
4. Send link by e-mail

To delete shared file or modify link properties: File Station -> Tools -> Shared Link Manager

How to backup your files from public cloud systems

Cloud Sync: synchronize with other cloud services
Menu -> Cloud Sync -> pick cloud to be synchronized -> authenticate
E.g. Dropbox
Connection Name: Dropbox
Local Path: cloud -> home -> Create Folder -> DropBox
Remote Path: Pick folder to be synchronized
Next -> Apply

3D Printing in the Math Dept

1. Find a ready-made 3D model at thingiverse.com
   or
2. Make your own at tinkercad.com or with your favorite 3D modeller (blender, FreeCAD, ...)
3. Email your 3D model (.STL file) to 3dprint@math.cmu.edu and tell us what color/filament type you prefer. We currently stock: Black PLA, Silver PLA, Orange PETG, Black PETG and Black ABS
4. Monitor your model being printed at http://prusa.math.cmu.edu:8080/?action=stream (must be on campus network or VPN)
   

   

5. Pick it up from Room 6102

We can advise on the best filament type for your model / use, otherwise refer to https://en.wikipedia.org/wiki/3D_printing_filament
