Data::SecsPack is a Perl module pack and unpack numbers in accordance with SEMI E5-94.

SYNOPSIS

#####
# Subroutine interface
#
use Data::SecsPack qw(bytes2int config float2binary
ifloat2binary int2bytes
pack_float pack_int pack_num
str2float str2int
unpack_float unpack_int unpack_num);

$big_integer = bytes2int( @bytes );

$old_value = config( $option );
$old_value = config( $option => $new_value);

($binary_magnitude, $binary_exponent) = float2binary($magnitude, $exponent, @options);

($binary_magnitude, $binary_exponent) = ifloat2binary($imagnitude, $iexponent, @options);

@bytes = int2bytes( $big_integer );

($format, $floats) = pack_float($format, @string_floats, [@options]);

($format, $integers) = pack_int($format, @string_integers, [@options]);

($format, $numbers, @string) = pack_num($format, @strings, [@options]);

$float = str2float($string, [@options]);
(@strings, @floats) = str2float(@strings, [@options]);

$integer = str2int($string, [@options]);
(@strings, @integers) = str2int(@strings, [@options]);

@ingegers = unpack_int($format, $integer_string, @options);

@floats = unpack_float($format, $float_string, @options);

@numbers = unpack_num($format, $number_string), @options;

#####
# Class, Object interface
#
# For class interface, use Data::SecsPack instead of $self
#
use Data::SecsPack;

$secspack = Data::SecsPack; # uses built-in config object

$secspack = new Data::SecsPack(@options);

$big_integer = bytes2int( @bytes );

($binary_magnitude, $binary_exponent) = $secspack->float2binary($magnitude, $exponent, @options);

($binary_magnitude, $binary_exponent) = $secspack->ifloat2binary($imagnitude, $iexponent, @options);

@bytes = $secspack->int2bytes( $big_integer );

($format, $floats) = $secspack->pack_float($format, @string_integers, [@options]);

($format, $integers) = $secspack->pack_int($format, @string_integers, [@options]);

($format, $numbers, @strings) = $secspack->pack_num($format, @strings, [@options]);

$integer = $secspack->str2int($string, [@options])
(@strings, @integers) = $secspack->str2int(@strings, [@options]);

$float = $secspack->str2float($string, [@options]);
(@strings, @floats) = $secspack->str2float(@strings, [@options]);

@ingegers = $secspack->unpack_int($format, $integer_string, @options);

@floats = $secspack->unpack_float($format, $float_string, @options);

@numbers = $secspack->unpack_num($format, $number_string, @options);

Generally, if a subroutine will process a list of options, @options, that subroutine will also process an array reference, @options, [@options], or hash reference, %options, {@options}. If a subroutine will process an array reference, @options, [@options], that subroutine will also process a hash reference, %options, {@options}. See the description for a subroutine for details and exceptions.

The subroutines in the Data::SecsPack module packs and unpacks numbers in accordance with SEMI E5-94. The E5-94 establishes the standard for communication between the equipment used to fabricate semiconductors and the host computer that controls the fabrication. The equipment in a semiconductor factory (fab) or any other fab contains every conceivable known microprocessor and operating system known to man. And there are a lot of specialize real-time embedded processors and speciallize real-time embedded operating systems in addition to the those in the PC world.

The communcication between host and equipment used packed nested list data structures that include arrays of characters, integers and floats. The standard has been in place and widely used in China, Germany, Korea, Japan, France, Italy and the most remote corners on this planent for decades. The basic data structure and packed data formats have not changed for decades.

This stands in direct contradiction to the common conceptions of many in the Perl community and most other communities. The following quote is taken from page 761, Programming Perl third edition, discussing the pack subroutine:

"Floating-point numbers are in the native machine format only. Because of the variety of floating format and lack of a standard "network" represenation, no facility for interchange has been made. This means that packed floating-point data written on one machine may not be readable on another. That is a problem even when both machines use IEEE floating-point arithmetic, because the endian-ness of memory representation is not part of the IEEE spec."

There are a lot of things that go over the net that have industry or military standards but no RFCs. So unless you dig them out, you will never know they exist. While RFC and military standards may be freely copyied, industry standards are usually copyrighted. This means if you want to read the standard, you have to pay whatever the market bears. ISO standards, SEMI stardards, American National Standards, IEEE standards beside being boring are expensive. In other words, you do not see them flying out the door at the local Barnes and Nobles. In fact, you will not even find them inside the door.

It very easy to run these non RFC standard protocols over the net. Out of 64,000 ports, pick a port of opportunity (hopefully not one of those low RFC preassigned ports) and configure the equipment and host to the same IP and port. Many times the software will allow a remote console that is watch only. The watch console may even be a web server on port 80. If there is a remote soft console, you can call up or e-mail the equipment manufacturers engineer in say Glouster, MA, USA and tell him the IP and port so he can watch his manchine mangle a cassette of wafers with a potential retail value of half million dollars.

SEMI E5-94 and their precessors do standardize the endian-ness of floating point, the packing of nested data, used in many programming languages, and much, much more. The endian-ness of SEMI E5-94 is the first MSB byte, floats sign bit first. Maybe this is because it makes it easy to spot numbers in a packed data structure.
The nested data has many performance advantages over the common SQL culture of viewing and representing data as tables. The automated fabs of the world make use of SEMI E5-94 nested data not only for real-time communication (TCP/IP RS-2332 etc) between machines but also for snail-time processing as such things as logs and performance data.

Does this standard communications protocol ensure that everything goes smoothly without any glitches with this wild mixture of hardware and software talking to each other in real time? Of course not. Bytes get reverse. Data gets jumbled from point A to point B. Machine time to test software is non-existance. Big ticket, multi-million dollar fab equipment has to work to earn its keep. And, then there is the everyday business of suiting up, with humblizing hair nets, going through air and other showers with your favorite or not so favorite co-worker just to get into the clean room. And make sure not to do anything that will scatch a wafer with a lot of Intel Pentiums on them. It is totally amazing that the product does get out the door.

LAMMPS project is a Molecular Dynamics Simulator.
LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grain systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the mesoscale or continuum levels.
LAMMPS runs on single-processor machines or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality.
LAMMPS is distributed as an open source code under the terms of the GPL license.
Enhancements:
- Changed to using NIST values for constants.
- A potential problem with alloy interactions has been fixed.
- Improved flexibility of user customization of output.
- The ability to add new styles of atom has been improved.
- A new atom method library, non-orthogonal lattice support, and support for semiconductors have been added.
- There are code speedups and bugfixes.

plconfig is a tool for configuring HomePlug powerline bridges. HomePlug specification based powerline bridges are becoming increasingly popular. Ive got myself two of them; the brand name is "ZEUS"; a strange brand that only seems to exist in Switzerland, and some people say its actually ZyXEL (have a look at the guts). Whatever, according to the HomePlug alliance homepage (www.homeplug.org), there are only two manufacturers of powerline ICs at the moment: Intellon and Cogency Semiconductor. My bridges have the Intellon chipset (INT5130 integrated powerline MAC-PHY transceiver and INT1000 analog conversion IC). Intellon calls their implementation "PowerPacket".
Now, about the only thing that has to be configured with these is the encryption password, so your neighbor wont be able to sniff your data. A Windows program is provided for that purpose - you hook up the bridge directly to your PC, enter a 2-24 character password, and the password is saved into the bridges EEPROM.
This is a bit of an inconvenience to non-Windows users, and even if you keep Windows boxes around, at least to me the software looks ugly. It keeps running strange daemons (WinPlcMan.exe, BridgeDeCor.exe, etc.) that use up to 100% CPU at times, and sometimes its not possible to set the password without power cycling the bridge first (although that seems to be the fault of the bridge).
So I made an attempt at writing a program to set up the encryption key. I found some inofficial information on the web, and it agreed with what I learned from sniffing the communication between the PowerPacket setup software and the bridge.
Im making the program available here for you to try; its status is currently somewhere in between an ugly hack and a simple use-once-and-throw-away tool. I have no idea if it works with other powerline bridges; although it should work with all Intellon-based ones. If youve had success with a particular product, please let me know!
Besides setting the encryption key, it can also capture and display powerline bridge management-related packets and request statistics from the bridge(s).
Enhancements:
- plaintext passwords are now hashed correctly as per the HomePlug specification (no longer homebrew MD5); as such passwords should now be compatible with the Windows setup software supplied by Intellon (note that -s does no longer set up the same key as in 0.1! Of course -s 0x behaves as before...)

Text::LooseCSV is a highly forgiving variable length record text parser; compare to MS Excel.

SYNOPSIS

use Text::LooseCSV;
use IO::File;

$fh = new IO::File $fname;
$f = new Text::LooseCSV($fh);

# Some optional settings
$f->word_delimiter("t");
$f->line_delimiter("n");
$f->no_quotes(1);

# Parse/split a line
while ($rec = $f->next_record())
{
if ($rec == -1)
{
warn("corrupt rec: ", $f->cur_line);
next;
}

# process $rec as arrayref
...
}


# Or, (vice-versa) create a variable-length record file
$line = $f->form_record( [ Debbie Does Dallas,30.00,VHS,Classic ] );

Why another variable-length text record parser? Ive had the privilege to parse some of the gnarliest data ever seen and everything else I tried on CPAN choked (at the time I wrote this module). This module has been munching on millions of records of the filthiest data imaginable at several production sites so I thought Id contribute.

This module follows somewhat loose rules (compare to MS Excel) and will handle embedded newlines, etc. It is capable of handling large files and processes data in line-chunks. If MAX_LINEBUF is reached, however, it will mark the current record as corrupt, return -1 and start over again at the very next line. This will (of course) process tab-delimited data or whatever value you set for word_delimiter.
Methods are called in perl OO fashion.

WARNING this module messes with $/ line_delimiter sets $/ and is always called during construction. Dont change $/ during program execution!

DigiTemp uses a simple serial port adapter to read temperatures from the Dallas Semiconductor 1-Wire DS1820 digital temperature sensors.
DigiTemp supports the DS9097-U adapter, supports DS2409 based 1-Wire hubs, and features a 1-Wire walk that will display all devices on the LAN, not just temperature sensors.
Enhancements:
- This release combines all the binary releases into a single tar.gz, including Windows binaries compiled with Cygwin.
- It adds DS1923 Hygrochron support, and fixes some small bugs in the userial driver.
- A lockdev bug was fixed (wasnt unlocking when done).
- A crash in free_couplers() was fixed.
- There is better error reporting when trying to access serial ports that dont exist.
- This release is compiled for Windows with Cygwin.
- DS2490/9490 support still doesnt work well for the author, although others have had success with it.

Regress Pro is scientific/industrial software that can be used to study experimental data coming from spectroscopic ellipsometers or reflectometers.

Regress Pro has been developed mainly for the application of thin film measurement in the semiconductor industry.

The software is suitable both to determine the thickness of the layers and to determine the optical properties of dielectric materials.

SYNOPSIS

Plenty of people have learned WWW::Mechanize, and now, you can too!
Following are user-supplied samples of WWW::Mechanize in action.

You can also look at the t/*.t files in the distribution.

Please note that these examples are not intended to do any specific task. For all I know, theyre no longer functional because the sites they hit have changed. Theyre here to give examples of how people have used WWW::Mechanize.

Note that the examples are in reverse order of my having received them, so the freshest examples are always at the top.

Starbucks Density Calculator, by Nat Torkington

Heres a pair of scripts from Nat Torkington, editor for OReilly Media and co-author of the Perl Cookbook.

Rael [Dornfest] discovered that you can easily find out how many Starbucks there are in an area by searching for "Starbucks". So I wrote a silly scraper for some old census data and came up with some Starbucks density figures. Theres no meaning to these numbers thanks to errors from using old census data coupled with false positives in Yahoo search (e.g., "Dodie Starbuck-Your Style Desgn" in Portland OR). But it was fun to waste a night on.

Here are the top twenty cities in descending order of population, with the amount of territory each Starbucks has. E.g., A New York NY Starbucks covers 1.7 square miles of ground.

New York, NY 1.7
Los Angeles, CA 1.2
Chicago, IL 1.0
Houston, TX 4.6
Philadelphia, PA 6.8
San Diego, CA 2.7
Detroit, MI 19.9
Dallas, TX 2.7
Phoenix, AZ 4.1
San Antonio, TX 12.3
San Jose, CA 1.1
Baltimore, MD 3.9
Indianapolis, IN 12.1
San Francisco, CA 0.5
Jacksonville, FL 39.9
Columbus, OH 7.3
Milwaukee, WI 5.1
