The Project Control Meeting
Agenda for Monday April 12, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
Installation of the LLO PSL
has commenced
George Grant construction has started erecting steel for our support
building. The skeleton takes shape.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
After HYTEC wrapped up their visit installing and schooling us on the
Actuation Control Rack on 4-1, the Crossbeams were installed on BSC4.
A
few more items required for the next tasks were procured, modified,
and
cleaned and we were ready to move on to Phase 2 for the in-vacuum hardware.
On 4-6 the BSC4 Dome was pulled and our work platforms installed.
On 4-7
the two Support Tubes were installed without using the Rail System!
Our
installation fixture here consists of a spreader beam that lifts the
Tube
from the Roller fixture, runs the Tube inside until a transfer to inside
lift points can be made and then continues the Tube to its final position
where it's held by the Jib Cranes (Bellows Maintenance Fixture.)
This
worked very well with the exception of the very clean SST turnbuckles
that
are used to transfer the pick points-these did not like turning with
the load.
Currently the Downtube/Optics Table heading to BSC4 is ready for inspection
and cleaning 4-8pm before installation. We expect to have the
remaining
items (Springs & Seats) for the completion of BSC4 early to mid
next week.
Meanwhile we will fire up the Control Rack again and position the Optics
Table in BSC8 before the Optics installation planned ASAP.
Optics:
----------------
(D. Cook)
We have had slow progress toward the FM and ITM installations this
week. We have had delays in the optic bake, magnet failure problems,
delivery delays as well as installation fixture setbacks. We are hoping
to
at least get the FM installed before Friday while Ken Mason is on site.
The
ITM will more than likely be postponed until Monday. We have made a
new
lapping fixture for the magnets and will have some of the other gluing
fixtures soon.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
This past week was spent pulling cables for the PEM dust monitors and
microphones. All the cable are in place and terminating has begun.
The
BNC cables to the microphones have all been terminated and we plan
on
terminating the dust monitor's cables next.
Began installation of the O2 monitors for all the buildings. This
is an
alarm system that will sound should we have a catastrophic failure
of the
LN2 system and oxygen is displaced.
In an attempt to mitigate our bug problem we shut off the exterior lights
on the buildings. They were acting as quite the homing beacon
for our
insect population. We hope that by shutting off the lights we
will only
have to battle local insects instead of the invading armies from miles
around.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
We have reached our bake temperature of 168 C.
We tried a new way to
regenerate the Cryopumps by the use of an electrical isolator.
This
allowed us to regenerate and keep power on the tube. The only
time we shut
down is for the installation of the aux turbo pump used for the
regeneration at each port and then their removal afterward. Using
this
procedure we lost only 10 to 15 C. We have repaired some insulation
problems and replaced some bad thermocouples found during this bake.
We
continue to prepare equipment for shipping to Livingston for their
bake.
Controls: Fixed scalable fonts on graphic user interface displays. Installed lights, receptacles, illuminated exit signs & laser safety sign in the "big house" (PSL enclosure). Installed power supplies and crates in 1x3, 1x5, 1x6 & 1x7. Moved cable tray and fittings into the big house. Received traansfer switch for UPS in mass storage room. Received and installed replacement power supply for Fore Systems in MSR returned broken unit to manufacturer. we are continuing to order parts and equipment for the electrical lab (Rus Wooley, Juilien Svoboda).
Beam tube bakeout preparation: A kickoff meeting with Ed Watt
of Pacific Industrial Insulation was held on
4-5-99. Some of the topics that were discussed are:
Optics & Vacuum Labs: (Jonathan Kern): PSL Safety Enclosure is completed. The suspended ceiling, and electricals should be finished by the end of the week. Culligan system remaining steady at 16 meg-ohms. PSL group are in site and have begun installation within the enclosure. The site Laser Safety Review was held Wednesday. Laser System Sponsors and Registered users need to check the LLO laser page at: http://www.ligo-la.caltech.edu/laser/, to be certain that they and their systems are in compliance with LIGO, and LIGO-Livingston Laser Safety procedures.
Facilities: The LLO Safety and Operational Readiness Review meeting was held April 7-8 at LLO. Attending were Gary Sanders, Rich Orr (chair), Mike Zydowicz, John Harrell, Bill Tyler, Caz Scislowicz, and Otto Matherny all participated in the review, along with LLO staff. The closeout report from the review committee stated that the LLO operational and safety procedures were "excellent" and well organized. The committee also had a number of LIGO-wide recommendations that apply to LLO and LHO, mostly centered around concerns about policies and procedures that insure that visiting scientists are able to work safely and efficiently, and that they are aware and accountable to the safety and operational policies of LIGO. These will be circulated in a written report to Gary Sanders. The committee also made a number of site-specific recommendations to LLO. Examples are marking of road edges, "open range" signs on the access road, review or external lighting for safety and security, installation of a smoke detector in the PSL enclosure, locations of fire extinguishers, etc. There were no serious issues that would halt installation activity at the site. Thanks to all at LLO for their hard and thoughtful work in preparing the procedures manual and in making this review a success.[GHS note: The review went very well and everything seems to be coming together at LLO for safe and efficient operations. Following receipt of the written report, we will introduce some new practices which will be announced in the weekly report. The LHO action items from last summer's safety and operations review were also fond to be closed out during this review.]
Weather Station/Suspension Test Stand: Feasible way to hook to
weather station has been found (at least from what is know to date) The
162 would talk with a control port of the weather station data logger.
Efforts under way to write C code capable of pulling the data into epics.
Dan Anderson of Campbell scientific (the data logger manufacturer), who
is an expert on serial
communications with the data logger has been consulted. Successfully
compiled state notation code on 162 and linked it with the
medm screen successfully. (Anthony Rizzi).
GRASP: Progress on Xmgr problem with the animate function but no resolution yet. (Anthony Rizzi)
PEM: Particle counters - Have obtained working software for collection
of particle counter data (Anthony Rizzi)
40 m Interferometer (Bill Kells/Nergis Mavalvala)
---------------------------------------
NO REPORT
----------------------------------------------
Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
Initial alignment (Zucker)
--------------------------
The damaged PLX retroreflector discussed here
last
week was declared DOA by the maker. They will
build us a new one at warp speed (4 weeks delivery)
which should come in just ahead of when it's
needed.
We simultaneously ordered a spare (to be sent
directly to LLO) to minimize any future risk to
the integration schedule.
ASC Initial Alignment (K.Mason, M. McInnis)
---------------------------------------------
Three new monuments were placed in Hanford for alignment of an optical
flat, FMy, and ITMy. We have not started any alignment yet due
to
problems with the alignment fixture. The alignment fixture bound in
the
differential screw requiring remachining. Tip/tilt screws in the lift
fixture were replaced with silver plated screws and the handle machined
to fit. We are currently assembling the cross bars and slide and then
will assemble everything in a clean tent prior to bringing it into
BSC-8.
Optical lever and ISC table fabrication (Matt Smith)
----------------------------------------------------
The optical lever table for the WX-arm in the LVEA was assembled and
put
into its final postion.
I replaced the photodiode assemblies with the modified version.
The
three optical levers that have the new version are 1) the W2K Recycling
mirror, 2) the W2K Y-arm input test mass and 3) the W2K Y-arm folding
mirror.
The new rails for the optical lever to the W2K foldmiror RX was ordered
and should be deliver to Hanford by Monday. The rails were needed
to
locate the photodiode in the proper position.
I am in the process of redesigning the remaing optical lever tables
to
be used at the Mid and End stations. The purpose of the redesign
is to
try to reduce cost, size, weight and assembly time.
Received the last of the quotes required to purchase the remaining parts
to the ISCT 9 and 10 tables that have been identified to date.
As of
now all the know parts have been ordered for these two tables.
There
remains a handful of parts that have yet to be determined.
ISC installation (P. Fritchel)
-------------------------------
o At LHO, I'm mainly helping to get the remaining small optics
prepared. The series of recent glue joint failures has prompted
a change in the parts preparation and gluing procedures (see
Helena's report). We are beginning to implement these for the
next round of attachment processing.
ISC implementation (Nergis Mavalvala)
-------------------------------------
Spent most of the week at Hanford participating in installation
and testing of IO CDS electronics. Powered up photodetectors,
mechanical shutters etc on IOT7 and tested the wavefront
sensing electronics with epics controls. We used the AM laser
to create a dummy wavefront signal and were able monitor it
out to the PZT driver. All gain changes and sign flips etc
were verified.
A cabling error destroyed the op-amps on the DC readouts of the
wavefront sensors on IOT7. These were replaced and, happily, the
large DC offsets we had been measuring previously were reduced
to ~2 mV on each segment. Some retuning of the wavefront sensors
was done to reduce phase shifts between opposite quadrants, which
are all below ~1 degree in the low gain setting. In high gain we
see large relative phase shifts (~30 deg) which is still being
investigated.
The discrepancy of Q measurements between the impedance test and
the directional coupling measurement was resolved with help from
Daniel S. Now both are in good agreement and reasonable. The EOMs
were tuned to within a few kHz of the desired frequency.

- Shipments of PSL equipment designated for LLO have been received,
intact,
for the most part.
- Installation of the LLO
PSL has commenced. The PSL electronics rack is
close to being completed. All VME modules
have been installed, along with
DC power supplies, the 10-W laser power supply,
and ancillary power
supplies. Cables have been dressed and
the ribbon cables cut to length and
terminated.
The network connection to the Baja4700E IOC has been
established.
The EPICS interface software will be checked out today (04/08).

2K Installation -
All of our time is begin spent on the magnet/epoxy problems:
(1) MC flat mirror (MCFM01-1)
Immersed the optic in a liquinox solution of the standard
concentration (40 cc liquinox in 2 l DI water) in such a way that only
the
HR surface (the surface that does not have magnets) was exposed to
the
solution and the side magnets were above the solution surface. The
beaker
containing the liquinox solution and the optic was placed in water
contained in the outer beaker. The water temperature was raised to
60 deg
C and kept at that temperature for 15 min. After cooling down the liquinox
temperature to <35 deg C, cleaned the HR surface with the liquinox
solution and lens tissues, according to the standard procedure. Repeated
this for four times until the optic passed the water test. (From the
third
run, the water temperature was raised to 70 deg C. During the final
rinsing by DI water, a side magnet&dumbell came off. The other
magnet&dumbell came off during the razor blade test carried out
after the failure of the first side magnet. Examined the dumbell surface
carefully, but nothing unusual was found.
(2) MC curved mirror (MCC2K02-1)
First cleaned the optic by the CO2 gun. Immersed the optic in a room
temerature, liquinox solution of higher concentration (~1.5 times higher
than the standard solution). Only the HR surface was exposed to the
liquinox solution. One top magnet (the dumbell stayed on the
optic) came off during the immerse. All the other magnets (magnets
only)
came of during the razor blade test made right after the failture of
the
first magnet.
(3) MC curved mirror (MCC2K01-1)
Immersed the optic in the same room temperature, higher concentration
liquinox solution for ~5 hours. Only the HR surface was exposed to
the
liquinox solution. Examined the HR surface cleanness every hour. Although
the cleannes improved every hour, it did not pass the water test. Then
immersed the whole optic in the same room temperature solution overnight.
In the following morning, one side magnet&dumbell was found to
have come
off.
(4) MC flat mirror (MCFM01-1)
Cleaned the optic by the standard procedure (same as (1) above). The
solution level was controlled very carefully so that the solution would
not touch the side magnets. One side magnet&dumbell came of by
itself in
the second immerse.
Bottom line: The process as it stands does
not work. Helena is
spearheading an effort to develop a more robust
process.
4K IFOs -
Optics and components for the Livingston 4K IFO have been shipped to
Livingston.
Small optics suspensions for both LLH and LHO 4K IFO are nearing
completion.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Bonding issues: A preliminary new procedure for
bonding magnets to aluminum
dumbbells is being drafted. This procedure incorporates
the multiple
suggestions received to improve the existing
one, as well as some quality
control measures. The tests will be done in Hanford.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
The Machine shop has moved in underneath the Metrology lab, we
we see an indication of vibration in most datasets, though the signature
is more clear when there is an optic with curvature being tested.
We are
trying to squeeze in as much BS01 data as possible before the machine
shop gets into full swing, we will then be able to quantify the impact
and
hopefully come up with data which clearly states the case for a move.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
Five sets of cavity beam dump housings were received, the vertical
support
structures are due on 4/9/99. Craig and Paul are finishing the layout

---------------------------------------------------------
Global Diagnostics System (Daniel Sigg, John Zweizig)
------------------------------------------------------
This week the work on the Data Monitor Tool chapter and the diagnostics
tests
chapter of the GDS Final Design Report were completed.
The first comments and bug reports about the C-language interface to
the
background monitor environment were returned and remedies for most
of the
problems were found. The current status of the C-environment is that
the
preliminary is compiling and running on Solaris and linux systems,
but the
porting to HP-UX is still in progress.
This shouldn't be difficult, but a
little more work is needed. Discussion has started on how to support
communication between users or operators and the background processes.
A run-time parameter package was added to the DMT environment (both
C and C++
versions) and documented on the Web. Further documentation on the DMT
in the
form of a FAQ page (currently very brief - more questions will be answered
as
they are asked) that includes description of how the DMT software is
distributed has also been added to the DMT web pages.
A proposal for an intersystem test between the diagnostics test system,
the ISC controller and the DAQ system was put together; it emphasizes
testing of data transfer paths between the excitation engine, the servo
front-ends and the network data server.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
The PEM interface plates were installed onto WBSC8.
The PEM stay clear zone railing parts are now at Hanford. There
are six
1" OD tubing that is in 12' lengths that need to be cut to size.
I have
preliminary lengths but wanted to double check that the as built hole
locations are okay before they are cut. Once I verify that the
lengths
are correct I will go ahead and buy the precut ones.
The balance of the RGA vacuume components were shipped to both sites
to
be cleaned and baked at the site at the next oportune time.
The beam tube PEM interface plates were delivered to Hanford and are
ready for installation.
I had designed two aditional adjustment plates the now can be mounted
to
the PEM BSC or HAM interface plates. These new plates allow the
repositioning of the shakers(PZT and E/M) to be along the axial position
of the seismic support tubes. These can only be used in the few
areas
that allow the space for assembly. Only one set was made and
is at
Hanford.
Optical Contamination (Daqun Li)
--------------------------------
The mirrors in cavity two which contains new viton
seats, were found
contaminated after the cavity was exposed to
moisture for a full
day (~ 70 ppm increase in total loss and 4 ppm
increase in absorption).
The viton seats residing in this cavity were
not washed with DI water
before loading. Again, the contaminated mirrors
will be sent to Rai Weiss
for further analysis using the SIMS technique.
No contamination has been observed so far from
cavity one also containing
viton after one moisture exposing test. The viton
seats in this cavity
cavity, however, were DI water-washed before
being loaded into the cavity.
I am trying to do the moisture test several times
to this cavity to see
if I can repeat the same contamination event
in this cavity.

- April 25 thru 30: Rolf @Livingston for NSF review and continued CDS
infrastructure installation.
PSL
====
- Installation started this week of the PSL system at Livingston.
MC LSC:
===============
All electronics and cabling for the Mode Cleaner Length Control are
installed at Hanford. The EPICS screens were finished and tested with
the
hardware, but not in 2X8 because the cables had not yet arrived. There
is
about one hour of in-place testing still needed. There is a set of
spare
modules also at the site.The electro-optic shutter controller has a
problem
and will be sent back for repair. A second one is being constructed
now and
should be ready in about two weeks. We are now working
on the proposal
for developing electronics for a one-arm lock at Hanford and the impact
that it will have on the Livingston Mode Cleaner effort.
We appreciate very much the help that Richard
McCarthy and Josh Myers have
been providing in getting things up and running
at Hanford. Thanks guys.
Timing System:
===============
The GPS Clock Driver is on hold until I put in a small change to make
it
capable of driving an ISC-110A as well as the ISC-110B and the ISC-115.
Then it will go out for prototype fabrication.
Hanford
========
New bootrom and vxworks code for 162-333/262 enables access to full
RAM space (8MB or 16MB). All Hanford Vacuum Controls 162 have been
replaced with 16MB 162-262 (except Mech Room, which is 8MB 162-333).
All Control room Sun Workstations have been upgraded to Solaris 2.7

PAYABLE HISTORY DATA.
From: Kris Duncan <kris@ligo.caltech.edu>
IOO : Sergei has reported the current status of his effort. Hiro asked
him for a list of modules he developed to designing the migration path
of the IOO modeling into the e2e standard distribution.
modeler : Hiro developed a stand along program which creates a data
file
used by the e2e detector module. Using this program, all (?) of the
detectors for LIGO can be simulated. He developed a I/O interface to
make it easy for the user to answer the questions of modeler and others.
Alfi : Ed worked on the development of alfi
1) Alfi 3.3.4 released
1.1) Corrected problem which prevented a module from properly detecting
all
changes made to it.
1.2) Fixed problem wich caused multiple definitions for a single
setting.
1.3) Fixed problem which caused recursive reference to primitives.
2) Worked on new Alfi User documentation.
3) Worked on Alfi Programmer documentation.
There was a discussion about the "instanciation" of box files among
Albert, Biplab, Ed and Hiro. The user will be warned when s/he tried
to
modify bases boxes which may cause inconsistencies. For that, a box
file
may have a locked/unlocked flag.
GW signal :
Matt and Hiro kept discussing how to implement in e2e the GW signal
in
the loweer level as the phase change of the field in the propagation.
e2e in Japan : Kawabe
Dr. Kawabe of Univ. of Tokyo (Tsubono group) will give a 20 minutes
talk
about e2e at Kamioka. Hiro sent him necessary materials and talked
over
phone explaining and answering questions.
* (JKB) Met with Phil, Bruce, Albert to discuss the managerAPI
meta-scripts for to prototype
high level commands for
getting Frame files to users.
Also, discussed command
parameters, syntax, authorization
and jobID reports..
* (JKB) Met with Albert to discuss numerical software standards
and style document under
LIGO number. Lazzarini has drafted
a specification/style document
to be circulated among LSC chairs, etc.
* (JKB) Met with Dave & Phil to prioritize tasks for the LDAS
software for the next few
days.
* (JKB) Began design and development of a parallel numerical
software system/library.
Components being reviewd and
tested consist of MPI with
ssh, Intel optimized BLAS
for LINUX, Fortran BLAS,
LAPACK, PETSCI. Also began
looking into ScaLAPACK and
parallel FFTs for this
layer of the LDAS software
implementation.
* (DF) Finished adding support for making reduced frames in the FrameAPI.
This will support the "getFrame"
demos.
* (DF) Finished setting up test framework for FrameCPP (i.e., changing
to the
'tests' subdirectory of the FrameCPP
distribution and typing 'make
check' compiles and runs the test
code).
* (DF) Fixed some memory leak problems with FrameCPP.
* (DF) The next distribution of FrameCPP is nearly complete.
* (DF) Met with Kent & Phil to discuss current status of the C++ code.
* (EM) Alfi 3.3.4
* Corrected problem which prevented
a module from properly detecting all
* changes made
to it.
* Fixed problem wich caused multiple
definitions for a single setting.
* Fixed problem which caused
recursive reference to primitives.
* Worked on new Alfi User documentation.
* Worked on Alfi Programmer documentation.
* (XHU) worked on digesting the 40m data into database
* (XHU) discussed with Bruce Allen on extracting data
from 40m
files
* (XHU) modified the LDAS event binaryinspiral table
* (XHU) computed and reformatted 40m data based on data
extracted
using the binary_reader program
* (XHU) is loading 40m event metadata into the database
* (BK) *** General Computing ***
1. Changed the LHO links
on the LIGO web site to point to
ligo-wa.caltech.edu.
LHO is maintaining their own web site.
2. Several LIGO and Amaldi
web site changes.
* (BK) *** LDAS ***
1. Continued work on the web application
for CDS. Finished forms for
displaying,
searching, exporting, and deleting a configuration.
Almost finished
with 2 forms for editing configurations --
one for editing
each line item in a configuration and one for
making global
changes or copying a configuration.
2. Prepared a web page for the
CDS table definitions that is posted
on the Data
Working Group bulletin board.
* (PSE) Met with Kent, Albert, and Bruce to discuss specifics of the
"User-Manager Protocol"
for processing user requests to the
LDAS.
* (PSE) Wrote the ILWD parsing namespace module for the generic API.
* (PSE) Began to write the loop management code for the manager,
frame, and metadata API's.
Lazzarini has been meeting with Raytheon and JPL people to arrange for
software support for LDAS from an existing large contract with JPL.
LDAS hardware activities:
Stuart Anderson:
After several months of painful work the final hardware replacement
for the LDAS prototype Beowulf was recieved, installed, and sucessfully
tested. There are now no known hardware problems with the cluster.
Other activities:
Roy Williams:
Upgrading Java on Ligo machines
Upgrading Tcl on Cacr machines as a foundation for installing TclBlend
Livingston:
Application S/W pkgs. are in the process of being ordered and delivered.
Hanford:
Nothing to report.
CIT:
Barbara changed the LHO links on the LIGO web site to point to
ligo-wa.caltech.edu. LHO is maintaining their own web site.
Several LIGO and Amaldi web site changes.
The plotter has been moved to the second floor of West Bridge.
The mail/print server has been upgraded to an Ultra 10. Along with
the
hardware upgrade the applications were also upgrade to later versions.
Another 9GB of disk space was added to the data2 area. A number of
old
accounts were cleaned off of the main systems. Other accounts will
also
be taken off after they have been copied to CD.
Update the Mathematica licenses.
Suresh has also finished the monthly backups. The tape drive on gsparc
has gone down so the backups took a little more time. Installed the
latest system monitoring package (SyMon 2.0) in the server system pollux
in one host mode. For multi systems in network environment, we need
to
obtain licenses from Sun. This package does provide detail information
about system's hardare, operating system, application softwares etc
status both graphically and numerically. This enables a system
administrator to quickly locate any potential problem.
Sean and Larry spent some time working on the modem pool. One of the
problem modems had a bad cable which has been replaced. Another modem
has
been configured and will be sent to Hanford for connection to thier
Livingston box.
A preliminary check of the box shows that it is configured correctly
but that the
modem (one of the old ones) may be having some problems.
Samantha is still rebuilding PC's and working on the documentation updates.
A number of contract and procurement issues have been addressed along
with Ed Jasnow working the issue of not being able to buy any hardware
from the CIT Bookstore.
Resolved a number of problems concerning printers and PC's along with
the
normal activities of setting up/changing of accounts.
Dorothy Lloyd
Began updating PO Log books and continued to work on reconciling the status reports and entering AP30 reports into the database. Processed the usual heavy load of purchase requisitions, POs, change orders, etc., and many invoices and receivers for payment. [See Cost Schedule Control Systems report submitted by Sarita Moore for further details.]
Continued to monitor and support the temp.
Irene Baldon
No report submitted due to my taking vacation and only having one day to report which was mainly taken up with sorting through and taking care of e-mail, voice-mail, mail, recording/mailing expense and/or advance checks and the same with airline tickets.
Rita Torres
For I. Petrac did change order No. 4 to Schober Machine and Engineering, and change order No. 2 to MIT on the PX contract number.
For M. Zydowicz did viewgraphs for presentation to be done at April 7 safety review. For W. Tyler updated action items resulting from last year's Operations Procedure review. For P. Lindquist distributed material for the upcoming CCB meeting. Also did labels and such to help organize reports in his office.
Finally got a response from Pagenet to obtain pricing information on email/voice capability. Have given information to A. Lazzarini and P. Lindquist to decide whether we should should accept. Set up three telecons one morning. Helped with mail in C. Mak's absence.
Elizabeth K. Wood
The power outage originally scheduled for mid-April, later moved to May 16, then changed July 11, has now been changed to July 18 to avoid problems with the Amaldi Conference participants who will be arriving at the Ath on July 11. We preferred that they come to an electrified atmosphere rather than one that was, well, dark.
Dealt with some travel issues while Irene was on vacation.
Continued preparations for the NSF Review in Livingston. This included locating appropriate photos for the binders and learning the joys of PowerPoint to create cover pages.
Began learning to get around the web-based IFIS/Oracle transition program called DataMart.
Used the web to locate beginner's information about HTML.
