Fast, simple object-to-object and broadcast signaling.
Blinker provides a fast dispatching system that allows any number of interested
parties to subscribe to events, or "signals".
Features:
- A global registry of named signals
- Anonymous signals
- Custom name registries
- Permanently or temporarily connected receivers
- Automatically disconnected receivers via weak referencing
- Sending arbitrary data payloads
- Collecting return values from signal receivers
SPARK stands for the Scanning, Parsing, and Rewriting Kit. It formerly had
no name, and was referred to as the "little language framework." The first
version (circa 1998) was described in the paper Compiling Little Languages
in Python at the 7th International Python Conference.
This Python module returns a tzinfo object with the local timezone
information under Unix and Win-32. It requires pytz, and returns pytz
tzinfo objects.
This module attempts to fix a glaring hole in pytz, that there is no way
to get the local timezone information, unless you know the zoneinfo
name, and under several Linux distros that's hard or impossible to
figure out.
JSON (JavaScript Object Notation) is a lightweight data-interchange
format. It can represent integers, real numbers, strings, an ordered
sequence of values, and a collection of name/value pairs.
QJson is a Qt-based library that maps JSON data to QVariant objects
and vice versa. JSON arrays will be mapped to QVariantList instances,
while JSON objects will be mapped to QVariantMap.
The tclreadline package makes the gnu readline available to the scripting
language tcl. The primary purpose of the package is to facilitate the
interactive script development by the means of word and file name completion
as well as history expansion (well known from shells like bash).
DNSCheck is a program that is designed to help people check, measure and
hopefully also understand the workings of the Domain Name System. When
used to check an domain (aka zone) is submitted to DNSCheck, it will
investigate the general health by performing various tests and sanity
checks.
WHAT IS DNSTRACER?
dnstracer determines where a given Domain Name Server (DNS) gets
its information from, and follows the chain of DNS servers back to
the servers which know the data.
Its behaviour is similar to ntptrace(8), which does it for the
NTP protocol.
Doc is an automated tool for verifying (to an extent) that a
domain is configured and functioning correctly. It makes no
attempt to validate the data inside a domain, only the structure.
The only required parameter is the valid domain name of an existing
domain. Example:
doc isi.edu.
MyDNS - SQL-based DNS server
This is the MyDNS package. MyDNS is a simple, non-recursive Internet
name daemon which serves records directly from an SQL database. It
currently works with either MySQL or PostgreSQL.
This version of the MyDNS package is a development of the original one
produced by Don Moore.

from nsping.8:
Nsping uses DNS queries to monitor reachability and operation of name-
servers, as well as the latency of DNS queries. It does this by sending
random recursive DNS queries to the nameserver (avoiding the effects of
DNS caching) and measuring the amount of time between the sending of the
query and the receipt of the response packet.
