PDL::Tips is a Perl module with small tidbits of useful arcana. Programming tidbits and such.

SYNOPSIS
use PDL;

# Whatever happens here.

This page documents useful idioms, helpful hints and tips for using Perl Data Language v2.0.

Help

Use help help within perldl or the pdldoc program from the command line for access to the PerlDL documentation. HTML versions of the pages should also be present, in the HtmlDocs/PDL directory of the PDL distribution. To find this directory, try the following

perldl> foreach ( map{"$_/PDL/HtmlDocs"}@INC ) { p "$_n" if -d $_ }

Indexing idioms

The following code normalizes a bunch of vectors in $a. This works regardless of the dimensionality of $a.

$a /= $a->sumover->dummy(0);

What is actually happening?

If you want to see what the code is actually doing, try the command

PDL::Core::set_debugging(1);

somewhere. This spews out a huge amount of debug info for PDL into STDOUT. It is planned to eventually make this redirectable and the messages selectable more accurately.

Many of the messages come from Basic/Core/pdlapi.c and you can look at the source to see what is going on.

If you have any extra time to work on these mechanisms, infrom the pdl-porters mailing list.

Prostat software is a statistic tool for Squid.

HOWTO

Archive prostat_1.3.tar.gz contains very little documentation so heres the extra short manual for how to use prostat:

1. install prostat package
2. make your own copy of /usr/local/prostat/prostat.conf and edit it as you want (or edit directly /usr/local/prostat/prostat.conf)
3. run

prostat +g

(or just prostat in case you do not make copy of prostat.conf)

Example:

cat /var/log/squid/access.log.0 | prostat +g/usr/local/prostat/myconf.conf -

this produces statistic for entries in rotated log using options stored in /usr/local/prostat/myconf.conf file (option LOGFILE is ignored while prostat (in this example) is taking log data from stdin)

Note: do not insert space after +g option

Tips:

- use prostat and crontab to generate statistic automaticly as often as you want
- look at analhead.h in source prostat_1.3.tar.gz archive for some information about command-line options

TrackIt is the first open source, web based project tracking tool designed from the ground up to provide maximum customization, flexibility and most importantly, usefulness to the developer.
Flexibility: Use TrackIt To Meet Your Needs
Aside from the simple definition of a Project and Users, every feature in TrackIt is optional. Furthermore, TrackIts dynamic linking system gives flexibility to define the links that make sense for your projects process. TrackIt also gives two powerful means to view your projects data. The first is a high level Listing capability, driven by HQL, to view common attributes of the projects items. The second is a raw SQL query used for reporting to CSV, a flexible format that imports into many tools such as Excel, Access, and Open Office.
Customization: Define Unlimited Project Item Types
Out of the box TrackIt comes with builtin support for several XP item types such as Features, Trouble Tickets, Test Cases, Derived Requirements, and many more. However, if these dont meet your projects needs, you can edit and add item types on the fly to make TrackIt work how you need it to.
Usefulness: Custom Developer Content
One of the primary goals of TrackIt was to be useful to the developer. Many Project Tracking tools do an adequate job of supporting project items, but come up short in terms of developer appeal. In TrackIt, each user has:
Up to four customizable RSS Feeds
A customizable rich content area useful for a todo list or personal notes
A high level view of all ticket types pertaining to the user
Eclipse Plugins for common activities (Preliminary support in 1.0 RC2)
On this site you will find links to resources and tips that will help your projects get the most out of TrackIt.
Enhancements:
- Better transactionality management, user interface enhancements, updates to dependent libraries, and several small bugfixes.
