In Part 1 of this two-part series, we covered why you should consider using the Amazon Elastic Compute Cloud (EC2) for your telephony solution. In this article, we will:

* Sign-up for Amazon Web Services (AWS);
* Setup the Elasticfox Firefox Extension for Amazon EC2;
* Configure an Amazon EC2 instance;
* Assign an Elastic IP address to the instance;
* Install Asterisk 1.6;
* Create Amazon Elastic Block Store (EBS) volumes for the Asterisk configuration, voicemail and logs storage.

he directory lists the device options available for accessing SIP based VoIP applications and content. Moore's Law like forces arising from the competition between the large number of companies producing SIP phones has produced a dramatic reduction in the cost of the devices. VoIP-Info lists hundreds of companies making softphones a hardphones. A few VoIP focused device distributors have emerged like VoIPSupply, Telephony Depot, and IP Phone Warehouse. ATA's represent the absolute cheapest path to SIP access, but the directory omits the devices as too closely linked to the old telephone model. The emerging competition between cell phone operating systems (iPhone, Android, LiMO, Symbian, Windows Mobile, etc) promises to provide very interesting platforms for SIP enablement.

The HP Web Security Research Group today released HP SWFScan, a free security tool for Windows that helps developers find security vulnerabilities in applications developed with the Adobe Flash Platform. We have found that developers building applications with the Flash Platform often leave security vulnerabilities unintentially in their code. Our group decided to develop SWFScan to help not only our customers but also developers around the world make the web a safer place.

When you need remote access and control another computer, you want to install vnc server on each computer for your company, it is mass work, also it post security risk.

VNC Java server solved the issue. Your client/user/employee only need access your website and run GSVNCJ applet, you can use any VNC viewer to control other computer. User runs GSVNCJ when need it only. No installation. Multi-languages supported.

CLiki is a Common Lisp wiki. It contains links to and resources for free software implemented in Common Lisp.

Non-Free, non-Unix and non-Common Lisp resources can be found at the ALU wiki.
All the Common Lisp resources can be found at The Common Lisp Directory.

If you're using Emacs to write Lisp code (either Common Lisp, Clojure, or some dialects of Scheme), you're probably also using SLIME (an Emacs major mode that provides enhanced support for Lisp development). With the recent surge of enthusiasm for Clojure, even more people are starting to use it. However, newcomers (and some experienced Lispers) frequently get confused with how to install and/or use SLIME. So, I've gathered together a bunch of links that (hopefully) will make SLIME easier to come to grips with.

The releases provide binaries that run on x86 (Intel Architecture 32) machines under the following operating systems: GNU/Linux, Mac OS X, OpenBSD, and Windows (95, 98, ME, NT, 2000, XP, and Vista). We additionally provide binaries for selected other architectures and systems, depending on the hardware and software that is available to us. We no longer support OS/2, DOS, or Windows 3.x.

Recent release notes are here.

In the future, we plan to deploy a new portable virtual machine; provide a port to the x64 architecture; and implement a module system. We also plan to finish support for R5RS, but we will not be providing support for R6RS. Other potential projects can be found on the tasks page

Lisp in a Box on Windows has been modularized!

* First, download the base installer and run it. This gives you GNU Emacs 21.3 and SLIME 2004-06-26.
* Next, choose an implementation's module, and install it:

his page, and the pages it links to, contain text of the Common Lisp book Practical Common Lisp published by Apress These pages now contain the final text as it appears in the book. If you find errors in these pages, please send email to [email protected]. These pages will remain online in perpetuity—I hope they will serve as a useful introduction to Common Lisp for folks who are curious about Lisp but maybe not yet curious enough to shell out big bucks for a dead-tree book and a good Common Lisp tutorial for folks who want to get down to real coding right away. However, don't let that stop you from buying the printed version available from Apress at your favorite local or online bookseller. For the complete bookstore browsing experience, you can read the letter to the reader that appears on the back cover of the treeware edition of the book.

’s really easy, so don’t fret. APC is free, and it’s a PECL extension, so there’s no need to re-compile PHP. What’s more, the default settings are pretty darn optimal, so there’s really no need to tweak the configuration once you’ve got it up and running. Keep in mind, since you’re going to be caching everything in memory, you’re going to need some memory to spare. So, don’t install this on a server with 256 megs of RAM, but don’t go thinking you need to run out and get something with 4 gigs of RAM either. You can get by just fine with a gig or so (even 512 if you want), and that’s a pretty standard amount you get with most dedicated / VPS setups these days. Anyway, rather than going into the actual details of installation, just check out the PHP page for APC. It’s got everything you need, including links to installing PECL extensions: www.php.net/apc.

APC Cache (Eaccelerator and other similar caches) is Fast but it is not distributed so you’re wasting cache and reducing possible hit rate by caching things locally if you have many web servers. MemcacheD is relatively slow but distributed and so you do not waste memory by caching same item in a few places, it is also faster to warmup as you need only one access to bring item into the cache, not access for each of web servers.

In hacker usage this quote has miscegenated with the U.S military's DefCon terminology describing ‘defense conditions’ or degrees of war alert. At GhandiCon One, you're being ignored. At GhandiCon Two, opponents are laughing at you and dismissing the idea that you could ever be a threat. At GhandiCon Three, they're fighting you on the merits and/or attempting to discredit you. At GhandiCon Four, you're winning and they are arguing to save face or stave off complete collapse of their position.

Solr is an open source enterprise search server based on the Lucene Java search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, a web administration interface and many more features. It runs in a Java servlet container such as Tomcat.

HP is a very fast programming language, but there is more to optimizing PHP than just speed of code execution.

In this chapter, we explain why optimizing PHP involves many factors which are not code related, and why tuning PHP requires an understanding of how PHP performs in relation to all the other subsystems on your server, and then identifying bottlenecks caused by these subsystems and fixing them. We also cover how to tune and optimize your PHP scripts so they run even faster.

ADOdb is a database abstraction library for PHP. There is also a Python version; see the ADOdb for Python docs.

The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions. Here is the complete list of drivers.

GoGrid Cloud Servers support a variety of Linux and Windows operating systems with preinstalled software, such as IIS, Apache, PHP, Microsoft SQL Server, and MySQL. Our Server images allow you to quickly deploy a single server or build a load balanced server network in just a few clicks without having to spend time installing software.

You write good code. But things can happen. How fast can you spot Rails performance problems—and their root causes? Don't rely on log files to solve tough performance problems. With New Relic RPM, you see problems in real-time, drill down to find the causes, fix them, and feel good again. You'll find the slowest ActiveRecord queries and slowest controllers. You'll trace transactions in fine detail. You'll see exactly where your app spends the most time. Monitor from development to production.

If you are trying to access a SOAP service from behind a firewall and your SOAP library does not have support for proxying network connections, you may not be able to get through by direct request. In such cases, you can use socket redirection programs to make the connection through a proxy server. Uche Ogbuji shows how to do so in this tip.

For experimentation and debugging, you can use almost any computer as a BOINC server. Before deploying a project more widely, make sure that your server has adequate performance, availability, and security. Some factors:

Use the idle time on your computer (Windows, Mac, or Linux) to cure diseases, study global warming, discover pulsars, and do many other types of scientific research. It's safe, secure, and easy

Writing scalable server applications in the Java™ programming language has always been difficult. Before the advent of the Java New I/O API (NIO), thread management issues made it impossible for a server to scale to thousands of users. The Grizzly framework has been designed to help developers to take advantage of the Java™ NIO API. Grizzly goals is to help developers to build scalable and robust servers using NIO and we are also offering embeddable components supporting HTTP, Bayeux Protocol, Servlet (Partially) and Comet

Atmosphere is a POJO based framework using Inversion of Control (IoC) to bring push/Comet to the masses! Finally a framework which can run on any Java based Web Server, including Tomcat,Jetty, GlassFish,Resin, Jersey,RESTlet etc….. without having to wait for Servlet 3.0 or without the needs to learn how push/Comet support has been differently implemented by all those Containers.

Just finished rewrite of the Java client for memcached and released it as version 0.9.6.

Meetup.com is currently testing memcached using this client code in our development environment. We plan on launching live with our next large code push.

A simple, asynchronous, single-threaded memcached client written in java.Efficient storage of objects. General serializable objects are stored in their serialized form and optionally compressed if they meet criteria. Certain native objects are stored as tightly as possible (for example, a Date object generally consumes six bytes, and a Long can be anywhere from zero to eight bytes).
* Resilient to server and network outages. In many cases, a client operation can be replayed against a server if it goes away and comes back. In cases where it can't, it will communicate that as well. An exponential backoff reconnect algorithm is applied when a memcached becomes unavailable, but asynchronous operations will queue up for the server to be applied when it comes back online.

ManyBrain Java Memcached client built for speed and high-scalability. Takes significant advantage of multi-core systems. Peak performance on loopback network at about number_of_threads = number_of_cores+2 (highly approximate). Throughput loss is gradual tested up to 500 threads. For real networks (with notably more latency than loopback) a few thousand threads should perform well (of course use, -Xss96k or so)

Very high performance for string and small payloads because of streamlined code. Large payloads (i.e., big hashmaps) still benefit, but less so as the Java serialization mechanism is a serious bottleneck.

This API is BETA and is not feature complete (yet). Notably, CAS is not supported.
