Printing

  • How to add Math printers in Leopard

    Mac OS 10.5 (Leopard) doesn’t auto-discover printers on Math’s network to the same effect as 10.4.If you have administrative rights on your machine, follow this url:http://localhost:631/admin?op=config-serverand find these lines:

    # Show shared printers on the local network.

    Browsing On

    BrowseOrder allow,deny

    BrowseAllow all

    You need to add a new configuration setting, so that this section of the config file looks like this:

    # Show shared printers on the local network.

    Browsing On

    BrowseOrder allow,deny

    BrowseAllow all

    BrowseProtocols cups

    • Click the “Save Changes” button, enter the username and password of a user with administrative rights and the cups server should restart.
    • Reboot the computer, open up System Preferences, and then the “Print & Fax” pane.
    • You should now be able to add the Math printers to your list of printers.
    • Again, you need administrative rights to do this.

  • How can I use the Math Department letterhead in a tex document?

    Brad Lucier has installed new math department letterhead macros for amstex and plain tex for the new tex.
    You need to have /pkgs/texlive/2005/bin/sparc-solaris/ early in your unix path to use these new macros.

    There are sample files showing how to use them at:

    /pkgs/texlive/2005/texmf-local/tex/plain/local/

    The short version is that after the

    \input amstex
    \documentstyle{whatever}

    lines (if any) say

    \input mathletter2006
    You can use the macros \address, \salutation, and \closing for the obvious things. By default, it uses a black-and-white version of the Purdue logo; if you have a color printer and want to use the black-and-gold version, say \goldlogo after you input mathletter.
    Tell Brad Lucier if you have problems (but please see plaintest.tex and amstextest.tex first).

  • How do I print one-sided using dvips?

    You can print one sided using dvips by using the following command:

  • How do I resolve missing font errors when launching Mathematica?

    This information contributed by Edray Goins.

    To use Mathematica via X Windows you must either have a local copy of or a font path directed to the following two directories:

    /pkgs/mathematica/SystemFiles/Fonts/BDF/
    /pkgs/mathematica/SystemFiles/Fonts/Type1/

    For example, on a Macintosh running X11 these folders should be copied and placed in the directory:

    /usr/X11R6/lib/X11/fonts/

    This way Mathematica will load without any error messages on missing fonts.

    • Again, you need administrative rights to do this.

  • Mac Mail.app is locked

    Mail.app locked mailboxes

    Email clients, like Mail.app and Thunderbird, like to know that they’re the only program accessing email stored on the local machine. This avoids potential email file corruption.

    Sometimes, however, these email clients get confused and insist that another program is writing to their files. If this happens to you, you can assure Mail.app that its files are okay by removing a lock file.

    From the command line, run this command:

    rm ~/Library/Mail/Envelope\ Index.lock

    From Finder, navigate from your home directory, to Library, to Mail and drag the Envelope Index.lock file to the Trash.

    Of course, sometimes Mail.app files really do get corrupted. If you continue to experience problems, you can reset Mail.app and wipe out all of its settings and start fresh*.

    From the command line, run this command:

    rm -rf ~/Library/Mail ; rm ~/Library/Preferences/com.apple.mail.plist

    Now open Mail.app and (re)create your mail account.

    * Sometimes a fresh start is a bad thing. If you use POP to grab your email from the server, you should not do this. If you have spent lots of time writing client side email filter/rules, you should not do this.

  • How do I reset my Math password?

    Have you ever forgotten your math password? Has your math password ever been reset due to that 120 day limit?

    Instead of waiting for Math IT to reset a forgotten or unknown password, you can now reset it yourself!

    All that’s required is that you provide the answers to some questions now. Later, when you wish to reset your math password, you’ll be asked those same questions and will need to provide the exact same answers.

    1. Pick and answer the questions on this page: https://www.math.purdue.edu/mathnet/securitychallengequestions/
    2. Forget your password.
    3. Follow the instructions on this page: https://www.math.purdue.edu/resources/resetpassword to reset your password.

  • How can I password protect a directory in my Math Web space?

    1. You need to create two files.
      1. ~/WWW/protecteddir/.htaccess
      2. ~/.htpasswd
    2. An .htaccess file can be used to specify webserver settings at the directory or file level. Here is a sample .htaccess file:
      • AuthName “Display name of protected area”
        AuthType Basic
        AuthUserFile /homes/ivetter/.htpasswd
        #require user ivetter
        require valid-user
    3. Your .htaccess file points to a file of usernames and passwords, commonly named .htpasswd
      1. To create your .htpasswd directory and place a user in the file on one of the departmental unix servers, run a command like this:
        1. htpasswd -c ~/.htpasswd username
        2. You’ll be prompted for the password twice.
        3. Voila! You should now have a username and encrypted password in the ~/.htpasswd file.
      2. To add another username to your .htpasswd file, run this command:
        1. htpasswd ~/.htpasswd username2
    4. Please note that your .htpasswd file can go anywhere in your home directory, but must be readable (but never writable!) by the ‘nobody’ user (or the world). Additionally, it’s best to not place the ~/.httpasswd directory under your WWW folder.

  • How to use www.mathjobs.org

    The Department of Mathematics is using the AMS backed mathjobs.org job application system for tenure-track and research assistant professors.

    Mathjobs.org provides nice documentation for Logging on, getting started as well as a User Guide and a short video introduction (in flash). Any question not answered by the available documentation can be asked of Math’s Web-Helpdesk.

    1. You should have received (yet another) password in an email to your math email account. Using that password you can Login to Mathjobs.org at https://www.mathjobs.org by clicking the “… as Faculty or staff at employer institutions” link (under the “Login to MathJobs.org” heading). Use your email address at which your received your temporary password for your username. Upon logging in, you will be asked to change your password. You must pick a password that does not include a “dictionary word”.
    2. Upon logging in, the list of applicants is displayed for our two open positions. TT is the Tenure Track Professor position, RAP is the Research Assistant Professor. (Please make sure both entries in *[RAP0018362007 TT0018372007]* are shaded green. If, for example, *RAP0018362007* is shaded gray, the listed applicants will not include those applying only for RaP’s. Click on either of these entries to go back and forth from green to gray.) Also, as the list of applicants grows, they will not all be display on the first page. Please click on the “ALL” button at the top (or bottom) of the page to display all applicants.
    3. Clicking on a name will open a new window with that applicant information. Here you can read the various parts of the application separately (cover letter, letters of recommendation, teaching statement, research statement, etc.). You can click on the “All” button at the very top (to the right of “Address“) to generate a single pdf file which is just like a complete paper application.
    4. For each applicant, one can assign Ratings, Refer the applicant to another faculty member, and even jot down private notes.
      1. Refer this appl to“: You can select other faculty on the list (right to the left of this box) who you think should also read it and select “email notify” to have the system send email to that person. Note: to select multiple usernames, one must hold down the the command key on a Mac (Mac command key icon), or the Ctrl key on a Unix or Windows machine.
      2. Your Private Notes. These notes appear as “yellow smiley faces” right below the applicants name once you return to the main Application List and after you click on the list again to update the system. These notes are only visible to you and the “managers” of the system who are the Department Head, Sally Goeke and the Webmaster.
    5. IMPORTANT: Please make sure you click on the “submit” button at the bottom of the screen or else your work will not be recorded!
    6. A useful tool for finding applicants that match specific parameters is the “Search” link at the top of the mathjobs.org webpage.

  • How do I show my publications from MathSciNet on my “bio” publications list?

    If you want to update your Publications list from MathSciNet by
    redownloading a list from MathSciNet, here’s how:

    1. Go to MathSciNet (the Resources page on the web site links to Rice’s mirror, which is quite fast).
    2. Search for yourself in the “Author” search box and hit return.
    3. It will give you a list of papers, some of which will be by you. Find a paper with your name and click on your name. Ensure that the list of papers is really by you.
    4. In the upper left of the page, beside “Batch Download:” choose “Citations (BibTeX)”.
    5. If you have 50 or fewer publications, hit “Retrieve First 50″ to the right of “Batch Download:”. If you have more than 50 publications, then one will have to mark the checkbox besides all the publications and then click “Retrieve Marked”.
    6. Copy all the data in the typewriter font to a file; I’d name it username.bib.
    7. On one the Solaris math servers (ie bessel), run this command in a terminal window:
      /opt/csw/bin/bibtex2html -nobibsource -nodoc -noheader -nofooter -q username.bib
      This will create username.html.
    8. If all your papers are in MathSciNet, copy username.html to
      ~/WWWbio/Publications/index
      Otherwise you can use username.html as the start of a more extensive web page of publications.
    9. If you want to indicate that the publications are from MathSciNet as of a certain date, then add a line like the following example to the top of the file named index:
      <h2>Papers listed in Math Reviews as of December 8, 2008</h2>

  • How do I edit my math bio page?

    Documentation for Math Bio pages exists here:
    www.math.purdue.edu/resources/computing/webdocumentation/bio/.

  • How do I have my personal homepage not listed on Math's Web Directory?

    To stop your Math homepage from being listed in the Departmental Web Directory, you should not have any files named: ‘index.php’, ‘Welcome.php’, ‘Welcome.html’, ‘index.cgi’, ‘index.html’, or ‘main.html’ in your WWW directory.

    Any files named ‘mainindex.html’ or mainindex.php’ will be served as the default main/index/welcome page and will not be linked to from the Web Directory.

  • How do I have my personal homepage listed on Math's Web Directory?

    If your homepage is on the math servers (at www.math.purdue.edu/~username) and a file on your webpage is named ‘index.php’, ‘Welcome.php’, ‘Welcome.html’, ‘index.cgi’, ‘index.html’, or ‘main.html’, the Web Directory will automatically link to your webpage.

    If your personal webpage exists somewhere other than the Mathematics Department servers, but you would still like it listed in the Departmental Web Directory, you should place redirect file in your Math Web Space. Specifically a file named index.html containing the following:
    <html>
    <meta http-equiv=”refresh” content=”0;url=http://www.yourhomepage.com/whatever” />
    </html>
    Please replace the url with your appropriate external url.

  • How do I put my webpage in my Math Web Space?

    Your Web Space exists at http://www.math.purdue.edu/~username You must replace username with your own username. To place content on your Web Space, you must create a WWW directory in your home directory. Everything within this WWW/ directory will be accessible from the web via www.math.purdue.edu/~username.

Email

  • Should I ever type my password into an email?

    No. Never type your password into an email.

    For more information see Is this a real email?.

  • Is this a real email or a spam or phishing email?

    “Phishing” is an attempt to criminally and fraudulently acquire sensitive information, such as usernames, passwords and other sensitive information, by masquerading as a trustworthy entity (from Wikipedia).

    Neither ITaP nor Math IT will ever ask you to reveal your password in an e-mail response, or over the phone, or in person. They will never send you a URL in an e-mail to click on that will ask you for your password; if necessary, they will give you instructions on how to get to a certain web page from the Math department home page or the Purdue home page. Additionally, neither ITAP nor Math IT will ever ask for any sensitive information (your date of birth, your Social Security Number, etc.).

    Please feel free to email helpdesk@math.purdue.edu if you’re wondering about a specific email; however, if you have any suspicions about an email, it’s probably spam.

    Sometimes, however, these email clients get confused and insist that another program is writing to their files. If this happens to you, you can assure Mail.app that its files are okay by removing a lock file.

    From the command line, run this command:

    rm ~/Library/Mail/Envelope\ Index.lock

    From Finder, navigate from your home directory, to Library, to Mail and drag the Envelope Index.lock file to the Trash.

    Of course, sometimes Mail.app files really do get corrupted. If you continue to experience problems, you can reset Mail.app and wipe out all of its settings and start fresh*.

    From the command line, run this command:

    rm -rf ~/Library/Mail ; rm ~/Library/Preferences/com.apple.mail.plist

    Now open Mail.app and (re)create your mail account.

    * Sometimes a fresh start is a bad thing. If you use POP to grab your email from the server, you should not do this. If you have spent lots of time writing client side email filter/rules, you should not do this.

  • Using Thunderbird from home or on a laptop

    Due to the way Math’s email servers are configured, email cannot be sent through them (to another destination) unless you are on the Math network (in the building and plugged into a Math network jack). Although one can still read mail from their math.purdue.edu email account, they must send through a different smtp server. Below is illustrated how to set up Thunderbird to receive email from a math account while sending email through Purdue’s servers. This configuration works anywhere and requires that you know both your Math login/password and your Purdue Career Account login/password.

  • Securing Email

    One, relatively easy, method for encrypting your email can be had through the use of an S/MIME certificate. Thawte is an international company that provides free email certificates.

    The below links provide some rudimentary documentation for signing up with Thawte, generating your certificate and installing it in your email client.

    1. Digital Signatures and Email Security
    2. Obtaining a Thawte Login
    3. Creating your Thawte Certificate
    4. Downloading your Thawte Certificate
    5. Installing your Thawte Certificate

    Please report any errors to helpdesk@math.purdue.edu.

  • Alligate options

    Alligate is the server-side spam blocking software that we love to hate. It blocks the vast majority of spam messages to .math.purdue.edu email addresses and is careful not to block legitimate emails. Below are some commands that you can use to get even more out of Alligate:

    To execute these options, send an email to the following address and include the option in the subject line.

    alligate@mailrelay.math.purdue.edu

    Note: You may receive a confirmation message you must respond to before the action is completed.

  • Purdue People Lookup in Mac Mail

    One can easily add lookup functionality to their email client that makes it trivial to find people’s email addresses given their names. By simply typing a name in the To: or CC: fields, Mac Mail will query an IT@P server for email addresses that belong to the typed name.

    Here’s how to set it up:

    • Open Mac Mail
    • From the top Menu goto Preferences:
      picture-3.png
    • Next, open the “Composing” tab on the top of the dialog windows and choose the “Configure LDAP” button:
      picture-4.png
    • Once the “Configure LDAP” window appears, click the +button in the lower left-hand corner. This window should appear:
      picture-6.png
    • You need to fill the fields as shown in the below image:
      picture-7.png
    • If you want to use the lookup functionaliy from off-campus, you should enter your Purdue Career Account username and password and set the “Auth Type” to SSL.
    • Click the “Save” button.
    • If you want to query the Mathematics Department server as well as Purdue’s, click the + sign in the lower, left-hand corner and fill out the fields with the below values:
      picture-8.png
    • Finally, click the “Done” button.
    • Be sure to check the “Automatically complete addresses” button on the “Composin” tab of Mail’s Preferences.

    Start a “New” email message, and type the name of a Purdue person, the name should automatically be translated into an email address.

  • What is Banner? why do I care?

    BANNER is the new administrative software that maintains student, financial and personnel data. The impact of Banner will result in three important changes beginning Fall 2008:

    (1) Course rosters will now be obtained online from Banner (or Blackboard Vista) . The old system SIS will no longer exist.

    (2) Final course grades will now be submitted online via Banner (or Blackboard Vista) . The old green sheets will no longer exist.

    (3) Plus or minus grades are now possible .
    (a) All 100 and 200 level courses are required to give final grades that may include +/- grades (where necessary).

    (b) For all single-section courses above 300, giving final grades that may include +/- (where necessary) is strongly recommended.

    (c) All multi-section courses above 300 are required to have a consistent policy regarding the giving or not giving +/- final grades (where necessary).

    Reminders:
    # You must use your Purdue Career Account, not your Math account.

    # You must be FERPA (Family Educational Rights and Privacy Act) certified in order to access BANNER (or Blackboard Vista). Certification information is available at: FERPA Certification

    # Be aware that you will have access to student data, most of which you don’t need. Privacy and security should be maintained when accessing student records.

    More information on Banner can be found through the departmental Banner webpage.

  • Where can I find New Account Information?

    You can find information about making adjustments to your Department of Mathematics account and other helpful information for new users on the New Account Information page.

  • How to use www.mathjobs.org

    The Department of Mathematics is using the AMS backed mathjobs.org job application system for tenure-track and research assistant professors.

    Mathjobs.org provides nice documentation for Logging on, getting started as well as a User Guide and a short video introduction (in flash). Any question not answered by the available documentation can be asked of Math’s Web-Helpdesk.

    1. You should have received (yet another) password in an email to your math email account. Using that password you can Login to Mathjobs.org at https://www.mathjobs.org by clicking the “… as Faculty or staff at employer institutions” link (under the “Login to MathJobs.org” heading). Use your email address at which your received your temporary password for your username. Upon logging in, you will be asked to change your password. You must pick a password that does not include a “dictionary word”.
    2. Upon logging in, the list of applicants is displayed for our two open positions. TT is the Tenure Track Professor position, RAP is the Research Assistant Professor. (Please make sure both entries in *[RAP0018362007 TT0018372007]* are shaded green. If, for example, *RAP0018362007* is shaded gray, the listed applicants will not include those applying only for RaP’s. Click on either of these entries to go back and forth from green to gray.) Also, as the list of applicants grows, they will not all be display on the first page. Please click on the “ALL” button at the top (or bottom) of the page to display all applicants.
    3. Clicking on a name will open a new window with that applicant information. Here you can read the various parts of the application separately (cover letter, letters of recommendation, teaching statement, research statement, etc.). You can click on the “All” button at the very top (to the right of “Address“) to generate a single pdf file which is just like a complete paper application.
    4. For each applicant, one can assign Ratings, Refer the applicant to another faculty member, and even jot down private notes.
      1. Refer this appl to“: You can select other faculty on the list (right to the left of this box) who you think should also read it and select “email notify” to have the system send email to that person. Note: to select multiple usernames, one must hold down the the command key on a Mac (Mac command key icon), or the Ctrl key on a Unix or Windows machine.
      2. Your Private Notes. These notes appear as “yellow smiley faces” right below the applicants name once you return to the main Application List and after you click on the list again to update the system. These notes are only visible to you and the “managers” of the system who are the Department Head, Sally Goeke and the Webmaster.
    5. IMPORTANT: Please make sure you click on the “submit” button at the bottom of the screen or else your work will not be recorded!
    6. A useful tool for finding applicants that match specific parameters is the “Search” link at the top of the mathjobs.org webpage.

  • How can I use the Math Department letterhead in a tex document?

    Brad Lucier has installed new math department letterhead macros for amstex and plain tex for the new tex.
    You need to have /pkgs/texlive/2005/bin/sparc-solaris/ early in your unix path to use these new macros.

    There are sample files showing how to use them at:

    /pkgs/texlive/2005/texmf-local/tex/plain/local/

    The short version is that after the

    \input amstex
    \documentstyle{whatever}

    lines (if any) say

    \input mathletter2006
    You can use the macros \address, \salutation, and \closing for the obvious things. By default, it uses a black-and-white version of the Purdue logo; if you have a color printer and want to use the black-and-gold version, say \goldlogo after you input mathletter.
    Tell Brad Lucier if you have problems (but please see plaintest.tex and amstextest.tex first).
