Eestes: Removed references to Rhel5

Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more.
The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). Its major features are that it's easy to use, supports both procedural and object-oriented (OO) programming, has powerful built-in support for text processing, and has one of the world's most impressive collections of third-party modules.

==Perl Versions==
While most modern operating systems ship with a version of Perl, UMIACS also maintains multiple versions.

===RHEL===
:For RHEL, different versions of Perl can be found via [[Modules | GNU Modules.]]
:The versions in /usr have PerlLocalLib support to allow users an easy way to install and maintain their own perl modules:

:* RHEL 6
:** /usr/bin/perl - 5.10.1
:** /opt/local/stow/perl-5.14.2 - 5.14.2

===Ubuntu===
:For Ubuntu hosts, different version of Perl can be install through the [[Ubuntu/SoftwareCenter | Ubuntu Software Center ]]
:The versions in /usr and /opthave PerlLocalLib support to allow users an easy way to install and maintain their own perl modules:

:* Ubuntu Trusty 14.04
:** /usr/bin/perl - 5.18.2

===WIN32===
:ActiveState Perl can be installed on your PC upon request. Contact [mailto:staff@umiacs.umd.edu staff] for details.

If you find that you need a version of Perl that is not readily available, you can always build it from [http://www.cpan.org/src/ source.]

==Installing Modules==
In order to ensure backwards compatibility and functionality, we prefer that users create their own installations of perl modules so that we can keep the central versions of Perl as vanilla as possible. The following instructions will show you how to [[Perl/Environment | setup and install local copies of Perl Modules.]]

==Documentation==
You can find full documentation for any version of Perl at http://www.cpan.org/modules/INSTALL.html. You can also find Perl tutorials (which can be fonud under the Manuals menu).

Eestes: Removed references to Precise

To provide a more up to date desktop linux experience UMIACS provides support for Ubuntu LTS (long-term support) releases. We will only be supporting LTS releases as there is a large amount of work that goes into testing the auto installer and supporting the more cutting edge Ubuntu releases.

Previous Ubuntu LTS (Long Term Support) releases are supported for 3 years on the desktop and 5 years on the server. Starting with Ubuntu 12.04 LTS, LTS releases will be supported for 5 years on both the desktop and the server.
* <b>Ubuntu 14.04 LTS</b> (Trusty)- End of life date: April 2019

===Features===
* Users have the ability to install software from blessed repositories without staff intervention.
* More bleeding edge desktop software experience than our RHEL offerings.

===Software===
Besides being able to install software from the blessed Ubuntu universes we provide only our binary software common tree to Ubuntu LTS releases. This is analogous to the traditional software found in <tt>/opt</tt> but is now found in <tt>/opt/common</tt>. The software includes Matlab, Mathematica, Compilers, etc. Starting with Ubuntu 14.04 LTS, you can use [[Modules]] to easily load these paths and relevant libraries into your environment. Also, please see [[Ubuntu/SoftwareCenter | Ubuntu Software Center]]

===Data Storage===
Please see the UNIX section in our [[LocalDataStorage]] article.

UMIACS has [[Matlab]] licenses that cover Linux, Windows and Mac. To access them you have to be using a university owned computer. If you would like to run Matlab on a machine that is not University-owned, you can check the pricing through OIT/SLIC [https://terpware.umd.edu/Windows/Title/1866 here]

==Linux==
Below are the different versions of Matlab across our supported linux workstations and servers. The one in bold is our latest version. RHEL5 is no longer supported as of R2013b, and 32-bit Linux distributions are no longer supported as of R2012b. For more information, please see [http://www.mathworks.com/support/sysreq/roadmap.html this page].

[[Modules | Modules]] is the preferred way to interact with Matlab and the page will provide information on adding Matlab into your environment and using it.

* Matlab r2012b
* Matlab r2013a (macOS 10.8+)
* '''Matlab r2013b''' (macOS 10.8+)

==License Troubleshooting==

Campus has a limited number of seats for Matlab itself, as well as the various toolboxes. When calling functions in a toolbox, Matlab will automatically check out a license, making it temporarily unavailable to other users. Sometimes it's necessary to check the number of toolbox licenses available.

===Windows License Troubleshooting===
On Windows machines, the necessary command is as follows. Please note that you may need to adjust the path to reflect the available Matlab versions and the installation path. Additionally, this assumes that you are using a 64-bit version. "win64" needs to be adjusted to "win32" on a 32-bit installation:
$MATLAB_PATH\etc\win64\lmutil lmstat -c "$MATLAB_PATH\licenses\network.lic" -f $TOOLBOX_SHORTNAME

As an example, here is how to query Matlab r2012b on a 64-bit Windows 7 host for the Aerospace Blockset Toolbox:
"C:\Program Files\matlab\r2012b\etc\win64\lmutil.exe" lmstat -c "C:\Program Files\matlab\r2012b\licenses\network.lic" -f Aerospace_Blockset

===Unix License Troubleshooting===
On Unix machines, the necessary command is as follows. Please note that you may need to adjust the path to reflect the available Matlab versions and the installation path. Additionally, this assumes that you are using a 64-bit version. "glnxa64" needs to adjusted to "glnx86" on a 32-bit installation::
$MATLAB_PATH/bin/glnxa64/lmutil lmstat -c $MATLAB_PATH/licenses/network.lic -f $TOOLBOX_SHORTNAME

As an example, here is how to query Matlab r2010b on our 64-bit RHEL6/RHEL7 hosts for the Parallel Computing Toolbox:
/opt/common/matlab-r2015a/bin/glnxa64/lmutil lmstat -c /opt/matlab-r2010b/licenses/network.lic -f Distrib_Computing_Toolbox

===Toolbox Shortnames===
The toolbox names themselves don't always work with this command; Rather, Matlab has a set of shortnames which can be passed to the lmstat command. The following are all the valid shortnames:

Aerospace_Blockset
Aerospace_Toolbox
Bioinformatics_Toolbox
Communication_Blocks
Communication_Toolbox
Compiler
Control_Toolbox
Curve_Fitting_Toolbox
Data_Acq_Toolbox
Database_Toolbox
Datafeed_Toolbox
Distrib_Computing_Toolbox

If you are having problems, feel free to contact [[HelpDesk | UMIACS Staff]], however please note that the Matlab license servers are hosted by campus' Division of Information Technology.

==Matlab Customizations==

You can tweak your Matlab experience using a file "startup.m". If this file is present in the current working directory where you launch Matlab, it will be executed. You can perform a variety of tasks using this file. These include (but are not limited to) customizing the window environment, setting variables for later use, and enabling use of 3rd party toolboxes. Alternatively, you can use the userpath env variable to set a path other than the current working directory for startup and 3rd party toolbox locations. Please see the following links for more information:

* [http://www.mathworks.com/help/matlab/ref/matlabrc.html Mathworks: Startup.m]
* [http://www.mathworks.com/help/matlab/matlab_env/startup-folder-for-the-matlab-program.html#bs6j57e-5 Mathworks: Userpath function]

GitLab

Eestes: Fixed links to permissions and markdown

GitLab is source code collaboration software based on [[Git]] source control management. It allows users to create their own repositories and share them with other users/groups or publicly. It supports built-in project wikis, code review, and issue tracking for each project. A full list of features can be found on the [https://www.gitlab.com/gitlab-ce GitLab] website.

All code is hosted on-site on UMIACS servers and is backed up nightly. We give all UMIACS users 5 projects with a soft limit of 400Mb per project. Projects that you create inside of a group namespace still count towards your project limit. UMIACS Staff can help create Lab groups (called namespaces) and delegate authority to manage the group to one or more faculty members. Permissions are assigned within GitLab. The UMIACS [[ApplicationResource|AR]] system is '''not''' used with GitLab.

To get started, navigate to the following URL in your browser and enter your UMIACS Krb5 credentials in the LDAP tab:

https://gitlab.umiacs.umd.edu

==GitLab Offsite Collaborators==
Any UMIACS user can now create an unlimited number of offsite
collaborator accounts for our Security Groups, GitLab and Object Store. These accounts can not create
repositories or groups, but may be given access to your repositories or
groups. You can find this utility in our [https://intranet.umiacs.umd.edu/requests Requests] application under [https://intranet.umiacs.umd.edu/requests/accounts UMIACS Collaborators].

==User Documentation==
GitLab provides user documentation that can be accessed at https://gitlab.umiacs.umd.edu/help. <b>Note:</b> you will need to log in to view this page.

Some of the most useful sections include:
* Permissions and user roles - https://gitlab.umiacs.umd.edu/help/user/permissions.md
* GitLab markdown for wikis and READMEs - https://gitlab.umiacs.umd.edu/help/user/markdown.md

==Repository URLs==
Users can download and clone directories from the remote repository using git clone. There are two different URLs that can be used: HTTPS and SSH.
You can view the URL underneath the Project title in the Project tab. Change the displayed URL by clicking on the URL type you want to see.
===SSH===
The SSH URL is more direct, though it is harder to set up. In order to do so, you will have to add an SSH key to your Gitlab account. Instructions to do so can be found [https://gitlab.umiacs.umd.edu/help/ssh/README here]. Once you have the SSH key added, you can log in without having to enter any credentials from the machine and account for which you created the SSH key.
===HTTPS===
The HTTPS URL is easier to set up- you just clone directly from the repository using the HTTPS URL. However, you will have to re-enter your credentials for GitLab every single time that you attempt to commit to, push to, pull from, or otherwise access the remote repository.
