"Identi.ca still doesn’t have a proper share button. For a long time I’ve looked for a good Identi.ca share button. One like Twitter’s, one that: displays a count of posts, and lets people share the page with the post automatically containing the page title and URL. I looked so long without finding anything that I wrote one myself. And I’ve talked a little bit about the half-PHP-half-JavaScript Identi.ca share button that I wrote, but I really haven’t shown it off or explained how to use it. It’s kind of pointless to write it just for myself. So allow me to explain a few things."

WaveMaker is a RAD development tool for Web and cloud apps, with more than double the monthly downloads of any other RAD tool. Its visual, drag, and drop tools flatten the Java learning curve by 92%, enabling any developer to build enterprise Web applications that deploy to a standard Java platform. The WYSIWYG studio creates standard Java applications with 98% less code, boosting developer productivity and quality without compromising flexibility. Applications are cloud-ready and include built-in support for multi-tenancy and elastic scaling.

Changes: This is the full Enterprise Edition, released under the Apache license. Other improvements include new widgets like popup menus, draggable trees and date time, a localization framework, a new JavaScript editor with auto-complete and debugging support, new functions, new events, and new properties, and a host of others.

Gearmand is the job server component of Gearman.
Gearman provides a generic framework to farm out
work to other machines, dispatching function calls
to machines that are better suited to do work, to
do work in parallel, to balance the load of
processing, or to call functions between
languages.

Changes: Defined workers can now return GEARMAN_SHUTDOWN. Benchmark worker can now be told to shutdown. Allocator code has been cleaned up (gearman_allocator_t). A "workers" option has been added to gearadmin. Workers will now default to -1 as a timeout (lowers CPU on the gearmand server for non-active workers). SO_KEEPALIVE is now enabled on client/worker connections. By default, workers now grab the unique value of the job.

nnmon is a central database and a Web interface for the nmon program’s data. It allows you to store and view nmon data instantly. nnmon_sender.pl is a pure Perl script. It runs the external nmon program and opens its output file for reading. Every line read from the file is sent to the nnmon_server.py program via TCP/IP socket. nnmon_server.py reads incoming data, parses it, and inserts the result to the database. nnmonweb is a PHP script that lets you view monitored systems in a tree. If there is data for a system for the last 12 hours, it will show a chart on the right hand side. The database and server components have been tested on RHEL 5.5. The client parts have also been tested on AIX 6.1 and RHEL 5.5.

Changes: This release puts AIX and Linux nmon data into a central database. You can view nmon data instantly on Web charts. It purges aged data automatically.

SQL Relay is a persistent database connection
pooling, proxying, and load balancing system. It
supports many database systems and programming
languages. There are drop-in replacement libraries
for MySQL and PostgreSQL, command line clients, a
GUI configuration tool, and extensive
documentation. The APIs support advanced database
operations such as binding variables, multi-row
fetches, client-side result set caching,
suspended transactions, query routing, and query filtering. It can be used for speeding up database-driven Web-based applications, accessing databases from unsupported platforms, migrating between databases, distributing access to replicated databases, and throttling database access.

Changes: The configure script was updated to detect modern versions of many languages and databases. The Java API should work on 64-bit machines now. The address="" bug is fixed. Oracle cursor bind and CLOB bugs were fixed. The maxsession parameter defaults to 0 (disabled) now. Patches were applied to improve stability under high load, manage race conditions, improve status reporting, and to address specific, unusual situations. Many obscure bugs, memory leaks, and border cases were addressed.

Changes: Major Features: native EXPath Packaging system support, client/server event notification, and a persistent document index to speed up access to large collections. XQuery: a new database and full-text functions; an event function added to fire events; index optimizations; better cost estimations. Commands: glob syntax has been added to database commands; new commands have been added; BACKUP has been optimized and renamed to CREATE BACKUP.

offrss is a standalone program that can download your favorite feeds and then show them in your favorite Web browser by spawning a simple local Web server. It will not only download the feeds’ text, but also the pictures, so you will also be able to read comics strips and enjoy posts with pictures in them while offline. It remembers what you read and what you don’t, and all the information stays in normal files, so you can synchronize it easily to any device that may not have an Internet connection. It can also work as a CGI to serve your feeds in your Web site, and it can update the feeds from crontab. It has few dependencies to build and can be cross compiled easily.

Changes: This release splits the feed posts into pages, still giving the ‘single html’ option, for those who like to print many posts to a paper-like device for e-book reading.

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I’ll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
