Date: Aug 02, 02 09:44:48 AM -0400

SPECIAL NOTICE:

The SSP PC, located in the area outside p/332/P333, has had two new 
programs installed on it, available for use by an SSP person. Photoshop 
- the image and photo editing program, and Canvas, a drawing and 
illustrating program are now installed. Manuals can be borrowed for use 
at the computer from Pete Nisenson and there are on-line help files as well.

Subject: new compute servers, cfassp0 and cfassp1
Date: Tue, 16 Oct 2001 12:10:31 -0400 (EDT)

  The division has purchased two compute servers from unexpected year-end
funds, allocated at the very last minute (literally). Due to the weird pricing
structure of Sun equipment, we bought two 2-CPUs machines rather than a single
4-CPUs (such a server is approximately 5 times more expensive).

  The new host names are CFASSP0 and CFASSP1. Both are a SunBlade 1000 with two
750MHz UltraSPARC III processors, with a 8-MB cache each, and 1024 MB of
memory.  They have been installed in the CF's machine room and are as of today
available for login and for your compute-intensive jobs. Please (re)nice your
non-interactive jobs to 10 to help share that resource, and enjoy.

Subject: SSPLC color printer new setup
Date: Tue, 9 Oct 2001 16:59:10 -0400 (EDT)

  The CF has fine-tuned the configuration of `ssplc' (the new HP2250TN color
  printer). As of now, the printer will use by default the `fast' print
  quality mode (instead of `best').

  You can select a different print quality mode when sending a (postscript)
  file to the printer, using either 'pslpr' or 'cprint', as follow:

  % pslpr  -d ssplc -SOutputMode=Normal FILENAME.ps
or
  % cprint -d ssplc -normal FILENAME.ps

and

  % pslpr  -d ssplc -SOutputMode=Best FILENAME.ps
or
  % cprint -d ssplc -best FILENAME.ps

From: SSP Computer committee (Pete N., Scott K., Sylvain K.)
To:   SSP division
Re:   New divisional computer hardware

  The division has bought some new hardware and supplies with the meager
divisional year-end funds available this year. The new hardware consists of
more disks, a color printer, and a public PC. Supplies consists of blank tapes
and recordable CDs.


  * Additional NetApp disks for SSP's pool and data disks:

      /pool/ssp has been increased from 120GB to 288GB.
      /data/ssp has been increased from  60GB to 108GB.

    To promote a more even use of SSP's pool space, files stored under
    /pool/ssp that are older than 90 days (3 months) will be deleted
    (automatically, every night). Remember that none of the /pool disks are
    backed up. /pool/ssp is ment for large temporary storage, see
    /pool/ssp/README.

    All /home and /data disks are backed up by the CF, use /data/ssp for long
    term storage.  The quota on /data/ssp has been increased to 4GB per user,
    see /data/ssp/README.

    **  All users of /pool/ssp should be aware that they might have files  **
    **  older than 90 days. These files will disappear overnight once the  **
    **  new scrubbing policy is in place (i.e., Monday Oct 1st).           **
    **                                                                     **
    *************************************************************************

    The new disks will be configured by the CF tomorrow morning (Sept. 25th)
    and should be available in their new configuration as of Wednesday
    (Sept. 26th)



  * A new color printer:

    An HP Inkjet color printer, located by Lisa Linarte office (next to the
    FAX machine), is available from all CF-managed machines, and has been
    named `ssplc'.

    Remember:

    1) Please do not change the printer setup. 

    2) Color printing is expensive, please use it only if and when
       appropriate.

    3) This is a low cost, hence lower quality color printer. Keep in mind
       that the CF supports better color printers.

    4) Do not use supplies that might damage the printer (in doubt, ask).



  * An Intel/MSWinME PC:

    A PC running Microsoft Window ME is available to all SSP users. This PC is
    located next to the public workstation (by P-333) has been named
    CFASSPC. 

    It is connected to the network, it is equipped with a CD writer, and has
    the complete suite of Microsoft Office software.

  Note:

   1) There is no system administrator for this machine. 
      Do not bother the CF if something is not working the way you want or
      need. 

      Pete Nisenson has volunteered to configure it and help keep it
      running. If you need any configuration change, ask or e-mail him.

   2) Do NOT install or remove any software.
      Do NOT change the system configuration, printer queues, etc... 
      Do NOT use/install any pirated software.

      Again, ask Pete for any configuration changes and/or enhancements.

   3) Please keep your files under D:\USERS\, and remember that
      there is no backup. Remove your file once you don't need them anymore.

   4) Please remains vigilant as to avoid infecting that PC with a virus.



  * The division keeps the following supplies:

     - DAT tapes               90m: 2GB
     - Exabyte tapes          112m: 5GB (on 8505 drives), 2GB (on 8500)
     - DLT tapes           DLT III: 15GB 
                       and DLT  IV: 40GB
     - blank CD-ROM disks      16x: 650MB

    These are kept in the cabinet under the b/w printer `ssplw' (by
    P-333). Use the black log book to help us keep track of supplies use. 

    The price of a tape scales with it's capacity. Try to use the right tape
    for the job (i.e., use only the large capacity tapes when needed).

Subject: membership in the "ssp" group on the CF-managed hosts
Date: Wed, 8 Nov 2000 11:11:00 -0500 (EST)

 The CF has informed me that when new accounts are created, new users are not 
automatically part of any divisional group (ie, like the group `ssp'). In
order to use some of the SSP computer resouces (like /pool/ssp and /data/ssp),
you must be part of the `ssp' group.

 To check what groups you are part of, use the unix command `groups'. To be
added to a group, contact SunHelp (sunhelp@cfa).

Subject: SSPLW: duplex assembly installed
Date: Wed, 27 Sep 2000 14:05:53 -0400 (EDT)

  The two-sided printing (ie duplex printing) adapter has been installed on
SSPLW. Check w/ the CF help pages how to print on bots sides...



From: Sylvain Korzennik 
Subject: new SSPLW printer
Date: Tue, 26 Sep 2000 17:13:14 -0400 (EDT)

  The aging and failure prone SSPLW printer (by P-333) has been replaced by a
new (HP 4050TN) printer. The new one works like the old one, and you should
see no changes.  Soon, the duplex printing optional accessory should be
delivered and SSPLW will be capable of printing on both sides of a page (with
the appropriate command option).

  This printer comes with two trays: when one is empty it switches to the
other one. These are called trays #2 and #3, each holds 250 pages; when both
are empty, please fill in paper in both trays. 

  Tray #1 is for manual feed, and is fed by opening the front panel marked
with a (1). Up to 10 pages can be piled up for manual feed (eg: letter head
paper). To print from the manual feed tray (aka tray #1), use the command
`hprint -manualfeed psfile', where psfile is the PostScript file to print. You
can also request paper from a special tray with the '-lowertray' and
'-uppertray' options to hprint. (Consult the CF help pages on printing for
additional info on printing options).



From: Sylvain Korzennik 
Subject: additional divisional disks and new workstations
Date: Wed, 13 Sep 2000 16:35:30 -0400 (EDT)

Dear SSP member,

  Thanks to the 2 for 1 deal w/ SUN, the division was able to purchased two
new 36 GB disks (in addition to the three anounnced earlier). These disks will
be very soon mounted on the NetApp (aka, the toaster called moonbeam).
 
  The total divisional disks space will remain configured with a 1/3 -- 2/3
split between /data/ssp and /pool/ssp. Hence (very soon):

  - /data/ssp:

     total quota: 60 GB
     user quota:   2 GB
     files are backed-up
     .snapshot is turned on

  - /pool/ssp:

     total quota: 120 GB
     no user quota
     no backups
     automatic deletion of files older than 6 months
     .snapshot is turned on

  The initial "expiration" time of 6 months for /ssp/pool, and the 1/3 - 2/3
split as well as the user quota can be adjusted according to the needs of the
division.

  Some 15 new workstations will also be purchased (12 from div. funds, 3 from
indiv. grants), allowing us to replace all sparc-class machines by ultra-class
ones.



From: Sylvain Korzennik 
Subject: new disks for SSP's users
Date: Fri, 11 Aug 2000 19:04:22 -0400 (EDT)

Dear SSP member,

  The division has acquired three new 36 GB disks, that are mounted on the
NetApp (the toaster called moonbeam). These disks replace the disks that were
mounted on ssp0 and ssp5, SSP's old servers. These servers (ie ssp0 and ssp5),
will be retired (turned off) as of Friday August 18th. The content of the
disks served by ssp0 and ssp5 will be moved to the new disks (see list below),
some time soon (either Tuesday 15th and Wednesday the 16th). The CF will
schedule these moves with the individual users who will be affected.

  The new disks have been configured as follow:

  - 1/3 as /data/ssp, ie:

     total quota: 36 GB
     user quota:   2 GB
     files are backed-up
     .snapshot is turned on

  - 2/3 as /pool/ssp

     total quota: 72 GB
     no user quota
     no backups
     automatic deletion of files older than 6 months
     .snapshot is turned on

  If and when more divisional funds will be available we expect to augment the
divisional disks. The initial "expiration" time of 6 months for /ssp/pool can
be adjusted according to the need of the division.

  For long term storage, use /data/ssp (by creating a subdirectory under
/data/ssp, I'd recommend to use your login name). Each user cannot have more
that 2 GB of storage under /data/ssp, the total storage capacity for all users
is limited to 36 GB .(This means indeed that there is not enough room for
everybody to store 2GB). Files stored under /data/ssp will be backed-up by the
CF.

  For large temporary storage, use /pool/ssp (again create a subdirectory
under /pool/ssp using your login name). There is a total storage capacity for
all users of 72 GB, with no individual quota.  Files stored under /pool/ssp
are not backed-up (although some short term recovery is available via the
.snapshot mechanism). Files stored under /pool/ssp and older than 6 months are
automatically deleted. 



FAQs
1. Where can I find a ZIP drive? 
There is a ZIP drive on the CF's public PC.



2. How do I create a PDF file from a LaTeX document that looks good
   in acroread? 

   To create PDF files of LaTeX documents that are easy to read 
   with a PDF reader (acroread) try this:
   
   a) First, generate a PS file from the .dvi file produced by LaTeX   
      with the -Ppdf option:

      dvips -Ppdf mypaper.dvi -o mypaper.ps

This is dvips(k) 5.86 Copyright 1999 Radical Eye Software (www.radicaleye.com)
' TeX output 2002.08.13:1645' -> mypaper.ps
...

   b) Next, run the Acrobat distiller (only in Solaris) with the -noprefs option:

      /opt/adobe/AcroBat/bin/distill -noprefs mypaper.ps

Distilling mypaper.ps (985,051 bytes)
5.5 seconds (0:06)    985,051 bytes PS  =>  553,127 bytes PDF  (56%)

   c) Check it out:

      acroread mypaper.pdf



3. Is there a way to incorporate LaTeX into a Power Point document?

Here is a site with downloadable sofware that allows easy use of Latex
symbols and formulas in Powerpoint presentations.
into powerpoint.

Texpoint (together with miktex, which may be optional if you use other
font files) allows you to use Latex in a window on a powerpoint slide in
order to generate a bitmap. This figure can be reduced, compressed or
otherwise distorted.
The web site from which you can download texpoint is

        http://raw.cs.berkeley.edu/texpoint/TEXPoint.htm 
There is also a tutorial in powerpoint that can be downloaded
and viewed.

4. How to set Sun's m64 video card to be 8 bit (or 24 bit) deep.
For Sun computer that have a m64 video card (like the SunBlade-100 and the SunBlade-1000), the video card can do either 8 or 24 bit color -- not both simultaneously. To work with IDL -- the way most people are use to -- it should be set to 8 bit (PseudoColor rather than TrueColor visual). A reboot of the computer is likely to reset it to the default 24 bit mode. To check, do /usr/sbin/fbconfig -prconf and look at the last 3 lines Possible depths: 8, 24 Current resolution setting: 1280x1024x76 Current depth: 8 or Current depth: 24 To reset it, do /usr/sbin/fbconfig -res 1280x1024x76 -depth 8 (or whatever resolution appeared above). Also, try: /usr/sbin/fbconfig -help and/or man fbconfig to learn more about frame buffer (aka video card) configuration.
