PSI/88 Version 1.0 by W. L. Jorgensen & D. L. Severance
To plot wavefunctions in three dimensions from
semi-empirical and most popular ab initio basis sets.
Valence semi-empirical, STO-3G, 3-21++G(*) and
6-31++G(d,p) basis sets are implemented for atoms
H-Ar.
On-line manual is available at this web site.
You can also download the source code of psi88 from
the above site as a ``psi88.tar.gz''. When you do ungzip and
untar this archive, you will obtain some documents and
the ``psi88.tar.Z'' file which is required at this port.
ChipVault is a VHDL and Verilog Chip Design Organization tool which improves
design efficiency by:
- Providing the ability to Navigate and Edit files Hierarchically.
- Automatically generating Schematic Component Port views of VHDL and
Verilog RTL files.
- Automating RTL instantiation and template generation.
- Providing Revision Control (designed for HW, not SW development).
- Supporting External Tool Hooks (bottom-up vcoms,etc).
- Providing an Issue Tracking Log with sorting.
- Providing Netlist sorting and hierarchy viewing.
- Supporting web-sharing of RTL files (both encrypted and clear).
- Fast and Nimble.
Psiconv is a file conversion utility that converts between Psion 5(MX) files
and more commonly-used *nux file formats. It can read Psion Word, TextEd,
Sketch, MBM, and Clipart files, and outputs HTML 3.2, HTML 4, ASCII, and
almost any graphical format. The libpsiconv library can also read Sheet files
and output Word and TextEd files for use in other programs. Included is full
documentation on several Psion 5(MX) file formats. This information is not
available from Psion (it has been reverse-engineered from Psion files), and
it's free for anybody to use.
Module XBase provides access to XBase (dBase, Fox*) database files,
namely dbf, dbt, fpt, ndx, ntx, mdx, idx and cdx. It provides native
Perl interface ($table->get_record, $table->update_record) to read
and write the tables. The index support is alpha and read only at the
moment.
Module DBD::XBase is a DBI driver that uses the XBase module
to work with the data, providing you with DBI compliant processing
interface and SQL commands ($dbh->prepare("SELECT * FROM TABLE")). As
an argument to DBI->connect, specify "dbi:XBase:$dir", where $dir is
the directory with the data files.
DBIx::Ease is intended to allow less-code DBI interactions.
Upon creation of a new DBIx::Ease object you should pass the portion of the DSN
(Data Source Name) common to all connections the object is supposed to store.
Replace the variable portions with '<databasename>'. Whenever you wish to make
only one connection you may enter the complete DSN, also when you want to make
connections with the same source but as different users, then call exec() with
different names of your choice as initial argument.
When searching through large amounts of data, it is often the case that a
result set is returned that is larger than we want to display on one page. This
results in wanting to page through various pages of data. The maths behind this
is unfortunately fiddly, hence this module.
The main concept is that you pass in the number of total entries, the number of
entries per page, and the current page number. You can then call methods to
find out how many pages of information there are, and what number the first and
last entries on the current page really are.
Rose::DBx::Object::Renderer generates web UIs for Rose::DB::Object.
It encapsulates many web conventions in the generated UIs as default
behaviours. For example, email addresses are by default rendered as
mailto links in tables and appropiate validation is enforced
automatically in forms. These behaviours are highly extensible.
Renderer uses CGI::FormBuilder to generate forms and the Google Chart
API to render charts. Template::Toolkit is used for template processing,
however, Renderer can dynamically generate a full set of UIs without
any templates.
sqldf is an R package for runing SQL statements on R data frames, optimized for
convenience. The user simply specifies an SQL statement in R using data frame
names in place of table names and a database with appropriate table
layouts/schema is automatically created, the data frames are automatically
loaded into the database, the specified SQL statement is performed, the result
is read back into R and the database is deleted all automatically behind the
scenes making the database's existence transparent to the user who only
specifies the SQL statement.
phpPgAdmin is phpMyAdmin (for MySQL) ported to PostgreSQL. phpPgAdmin is a
fully functional PostgreSQL administration utility. You can use it to create
and maintain multiple databases and even multiple servers.
Features include:
- create and drop databases
- create, copy, drop and alter
tables/views/sequences/functions/indicies/triggers
- edit and add fields (to the extent Postgres allows)
- execute any SQL-statement, even batch-queries
- manage primary and unique keys
- create and read dumps of tables
- administer one single database
- administer multiple servers
- administer postgres users and groups

Riak is an open source, distributed database. Riak is architected for:
* Low-Latency
Riak is designed to store data and serve requests predictably and quickly, even
during peak times.
* Availability
Riak replicates and retrieves data intelligently, making it available for read
and write operations even in failure conditions.
* Fault-Tolerance
Riak is fault-tolerant so you can lose access to nodes due to network partition
or hardware failure and never lose data.
* Operational Simplicity
Riak allows you to add machines to the cluster easily, without a large
operational burden.
