Enterprise Social Networking: Some Do, Some Don't
Date: 12/27/2007
- With heavy hitters IBM and Microsoft among the many vendors offering enterprises the tools with which to implement several different flavors of enterprise social networking, exactly how many staffers actually take part in any such activity – blogging, message boards, chat rooms and the like -- on or off duty is a wash. According to some very unscientific research conducted by TelecomWeb, the percentage of respondents to the question “What is your favorite form of online social networking?” who said they weren’t interested (29.7 percent) was nearly the same as the percentage of respondents who have profiles on MySpace or Facebook (27.8 percent).
- Some 20 percent of respondents told us they participated in chat rooms, while nearly 10 percent wrote or read blogs, close to 7 percent visit peer-to-peer Web sites and 5.6 percent post on message boards or receive e-mail from list serves.
- Does this mean your workers are goofing off on the job? Some may be, but the software being offered for enterprise social networking concentrates on two things: building internal relationships between workers and between management and staff, and building better bonds with the customer. For example, Lotus Connections has five components — activities, communities, “dogear” (a bookmarking system), profiles and blogs, all crafted for workers to connect and build new relationships based on individual needs." And Microsoft now offers new tools that will help IBM Lotus Notes/Domino customers take advantage of the new unified communication and collaboration innovations delivered as part of the Microsoft Exchange Server 2007, the 2007 Microsoft Office system and Microsoft Office SharePoint Server 2007 technologies. These resources include a new suite of tools for managing transitions of IBM’s directory, messaging and application solutions, as well as new templates for SharePoint Products and Technologies, which make it even easier for IT professionals to roll out customized applications for common business scenarios.
- According to published opinion, these products probably won’t have much of an impact on existing social networks like MySpace, Facebook and even business-focused LinkedIn (ever get one of those invitations to trade personal business info for networking purposes?). According to Microsoft, enterprise social networking “is more about collaboration and communication” than true social networking.
- Some even think Microsoft is destined to become “the Facebook of the enterprise.” Wachovia, the fourth- or fifth-largest U.S. banking concern (depending on what report you read), is using Microsoft social-networking solutions to serve 110,000 employees. Microsoft, bank officials say, offers “easy interconnection” with other applications via its Office SharePoint Server product, and such integration was key to the bank’s decision.
- The bank reportedly tested its social network in a "proof-of-business-value environment," rolling it out in three divisions so far, with a company-wide deployment set for next year. Features include search, presence awareness and information sharing on a variety of business topics along with access to employee-written blogs, wikis and an encyclopedia of all things Wachovia that some users within the bank nicknamed, inevitably, the “Wachipedia.” Staffers also can upload pictures of themselves, and community development is expected to be a primary benefit of the system. Wachovia also believes the system will be embraced by younger employees who are used to using social networking personally at home.

China's space industry leapfrogs
Date: 12/14/2007
- Chinanews, Beijing, Oct 12 – With 50 years of development, China's space industry has made great progress in mainly five aspects, said Sun Laiyan, director-general of the China National Space Agency, who is also deputy director of the Commission of Science, Technology and Industry for National Defense in an interview given on Thursday.
- First, China's entrance into space is considered as the fundamental requirement for a country to develop its space industry. At present, China has produced 12 series of Changzheng (Long March) carrier rockets, which have sent satellites into different orbits as required.
- Second, China is able to produce its own man-made satellites. So far, China has produced and launched more than 80 man-made satellites into space. These satellites included telecommunication satellites, remote sensing satellites, navigation satellites, satellites for scientific experiments, etc. All these satellites have been providing excellent services for the national economy in their respective fields.
- Third, China is able to send manned spacecraft into sky. In 1999, China sent its first unmanned spacecraft, Shenzhou 1, into space. In the following years, China had sent a series of Shenzhou spacecraft, including Shenzhou 2, Shenzhou 3, and Shenzhou 4, into space. In 2003, China sent the first manned spacecraft, Shenzhou 5, into space. Two years later, China further sent another manned spacecraft, Shenzhou 6. With the successful launch, China has become the third country in the world that can send manned spacecraft into space.
- Fourth, China has made great progress in its space exploration capability. China will launch the Chang'e moon probe satellite in the coming two months. The launch of the moon probe satellite will further show that after China made man-made satellites and launched manned spacecraft, China has moved another step forward in its deep space exploration.
- Fifth, China is able to improve the infrastructure and logistics construction for space industry. China is able to design, produce, and conduct pre-launch tests to carrier rockets and spacecraft. All these are considered as very important parts in infrastructure building. At present, China has built three satellite launching centers, one in Jiuquan, one in Xichang and one in Taiyuan. In addition, China has set up a space measuring and monitoring network that can put all the satellite-moving areas under its supervision.
Pay-Per-Click (PPC) Search Engines and Bidding by Beanstalk
Date: 11/23/2007
- Bidding on the pay-per-click search engines can be a time-consuming and constant effort. Getting the maximum return on your investment means weekly if not daily monitoring of your bids vs those of your competitors, evaluating which PPC engines to bid on, and choosing your keywords and then reviewing those keywords regularly. There are a number of resources and tools that claim to manage your PPC accounts however, like most things in the search engine world, there is nothing that can compare to the human touch. Below you will find links to articles on Pay-Per-Click engines and bidding strategies that can help you gain the information that you need to maximize your return-on-investment from these engines. Below the articles you will find links to some of the major PPC engines and a few of the secondary ones. More so than with directories and natural search engines the secondary PPC engines can be a great source of leads and revenue. While they will provide for less traffic, the cost-per-click (CPC) is generally far lower allowing you to bid for higher positioning, on more phrases, or on more engines.
- Articles on Pay-Per-Click Search Engines and PPC ManagementUsing PPC to Maximize Your Search Engine Positioning ROIPPC Resources
- Advertising on the PPC engines is fraught with risk. From the risk of loss by targeting the wrong keywords, bidding higher than your ROI would dictate (very common) and of course Click Fraud you need a tool to keep an eye on things. Here is what we’ve found to solve this important issue (this one falls into the tools we use category).
- Currently Offered at 50 OffSES San Jose 2007Dave Davies (CEO) had the opportunity to speak with Richard Zwicky from Enquisite. They have just launched a tool called PPC Assurance. This tool tracks all your PPC programs, reports where clicks are being paid for but not getting to your site (either your site is down or it’s a bot), when clicks are coming from the wrong locations and a wide array of other factors. The tool even creates and sends the request to get your credits back from the major engines when fraud is detected and/or suspected. I cant possibly get into all of the details however you can visit their site where they provide a great run through on their Preview page (note: you’ll have to click the image on the right for it to play).Major Pay-Per-Click Search Engines Perhaps the largest and best known of all the PPC opportunities is the Google AdWords program. With this program you will see a significant increase in traffic. the downfall is that due to its popularity the cost-per-click can be very high for competitive phrases.25 Bonus If there is a rival in PPC popularity then its with Overture. Again, you will witness a good increase in traffic however like with Google AdWords program, the cost-per-click can be very high. Secondary Pay-Per-Click Search Engines This one isn’t really a PPC but rather an annual subscription. You choose your keywords and pay a flat rate (12/yr) and you’ll be listed in the Sponsored Listings on Exactseek and 40 other directories. Beanstalk first purchased a listing when it was only ExactSeek and found it well worth the money, with the added power of the other engines and directories they’ve added its a great deal.25 Bonus Significant increases in revenue can be realized with this PPC engine. In the first week of testing this engine we saw significant increases in both traffic and revenue from the test site. They are currently giving away a 25 bonus for those who open accounts with an initial deposit of 50. We only wish they’d been offering this when we ran our trials. With a great track record and low bid costs this engine falls in our recommended PPC category. Bids start at 0.05/click which is higher than many of the secondary engines however with good click-fraud protection the quality of the traffic is higher. While this engine doesn’t seem to provide a ton of traffic it certainly seems to deliver in ROI. In our trials on this PPC engine we did not see a large jump in visitors to our site however they have a low CPC (cost-per-click) starting at just 0.01/click and because of their secondary classification they do not have the popularity that leads to high bid amounts. For ROI this is one of our favorites. Of all the secondary PPC engines that I we have tested and used ePilot seems to provide the most consistent high traffic. This engine is especially useful for sites in the health and fitness sectors.
ISV meet hoster, hoster meet ISV
Date: 11/16/2007
- You are an ISV looking at on-demand delivery of your application - good for you! But... once you have sorted out scalability, configurability, tackled multi-tenancy and packed it full with cool features, be prepared to keep developing as your Hoster may not be able to help as much as you might expect.
- In the summer Microsoft had lots of conversations with SaaS ISVs and Hosters to better understand the relationship that exists between them. One of the outputs is a white paper on MSDN.
- Here is an excerpt from the paper:
- "The case for specialized Software as a Service (SaaS) hosting can be easily rationalized by examining an incompatible pair of anecdotal fact and reality:
- ·Fact: When we explore the expertise of software vendors today, we find that most of them will not claim operating a hosting environment as a core competency. Actually, many would also cite operational excellence as a key barrier of entry into the SaaS market. This observation should not come as a surprise to the reader.
- ·Reality: However, when we take a look at the prevailing market situation, delivering SaaS applications often depends on hosting solutions that are "home-brewed" by the software vendors themselves. This is to say that in addition to implementing the application logic, many SaaS software vendors themselves will need to design, develop, and integrate the operational modules for their service offerings. As illustrated in Figure 1, the service delivery components, such as billing, metering, and logging, are built by the application vendor and integrated into the application stack.
- The key observation from the datum above is that many ISVs are re-implementing operational components by necessity, not because those infrastructure additions provide significant value to differentiating the core features of the applications. Moreover, building these components add to the time and cost of delivering the application. Therefore, for the software vendors, most of such redundant work and expenditure can be eliminated if the software vendors can obtain the same operational functions from third parties that specialize in SaaS hosting."
Tis the season to be... vigilant?
Date: 11/12/2007
- We've all heard the stories of people who come home after a hard night's partying just before Xmas to find that the local tea-leaves have been in and done a reverse-Santa, nicking all their presents from under the tree.
- What's less well publicized is that these days, businesses face increased seasonal theft risks too. For a start, your office may be only lightly staffed - and with all the lusers away scoffing mince pies, you might think it's a time of less risk and more opportunity to get on with the "housekeeping".
- Not a bit of it, reckon our chums in the network business. Data theft, cracking the office wireless LAN, stealing hardware - or simply using the office phones to run up big international call bills - all are more likely next week, they say.
- "Each new year we see a flurry of calls from network managers who have experienced problems over the holiday season," adds Helen Wadsworth, sales manager at iTracs.
- "Typically this time of year sees offices left with skeleton staff, who may not even be permanent employees, for prolonged periods. For a criminal, this provides an unparalleled opportunity to steal information or hardware from a network. This can be particularly hard to trace once the holiday season is over and things get back to normal."
- Her warning is backed up by a report from business insurance provider Zurich. It surveyed 1000 small British firms, finding that 28 percent expect to suffer some sort of crime over the winter - and over Christmas in particular.
- The important thing is it's not just the risk of a cleaner or temp nicking the stationery. It's also the time when, with network admins off enjoying a well earned break, criminals may target your network and your data too.
- So be pure, be vigilant - and make sure the IPS and the network monitoring systems are working properly before you hit the turkey and plum pudding.
10 Important Tips for a fast loading web site
Date: 11/02/2007
- It is important to have a reasonably fast loading web site so that viewers are not made to wait for a long time and to accommodate users on slow internet connections. Search engine algorithms also do take into consideration your load time.
- Follow these tips while designing and developing your site:
- Optimize your HTML code: Make sure that your site doesn't have any unwanted tags and that it is optimized.
- Effective Table designing: Design using nested tables instead of using cell merges and splits. Use separate tables where ever possible. Not designing for 100% height is better as if you use just one outer table, the web page is displayed only after the table is loaded fully. If many outer tables are present [you can have different tables for the header, content, footer, etc.] the page displays the content of each table as soon as its elements are loaded.
- Maximize content area: This not only reduces load time, it enhances the readability of your site.
- Minimize use of graphics, Flash, scripts: These are the major contributors to the size of your web page, so try minimizing them. Try using background colors and fills instead of heavy images.
- Optimize all heavy files: As much as possible optimize heavy graphics, Flash files and scripts. In editors like fireworks and flash you can see the various options in the preview panel to reduce the sizes. See how popular web sites like google and yahoo have pages that are very small in size and thus load in seconds.
- Stick to simple designs: Most fast loading sites have very simple designs. Take the hint! Complicated designs will slow down your pages.
- Spread out your content: In case you find yourself having very long pages of content, break them down into separate sections and thus bring down the sizes of the individual pages.
- Use Text Links instead of graphic buttons: basically try to make use of HTML as much as possible. Use CSS Styles for text links to make them as attractive as buttons. Read our CSS Styles tutorial
- Use Server Side Include (SSI) files where ever possible. SSI files once called from the web server reside in its cache so on subsequent requests they load faster.
- Using Layers instead of tables is a new concept for better load time. We will be bringing out an article on it soon.
- Check your Load time
- Do remember to check your Load time regularly. Use free site tools available on the internet (example: netmechanic.com) to check your site load time.
Australia 'Big Mother' monitors kids Web usage
Date: 10/26/2007
- The gold medalist was with Federal Communications Minister Helen Coonan today to promote Net Alert -- Protecting Australian Families Online -- in Sydney.
- Perkins, a father of three, said when his kids became Internet savvy it was the most daunting part of his parenting life.
- "My first big hit was when my daughter at seven was downloading videos from YouTube. That was when I really realised she was being exposed to things I had no control or say over, and that, as a parent, is one of the hardest lessons you learn," he said.
- "It's not negative, a Big Brother. More like Big Mother, protecting you and your kids from what's out there."
The US$189 million initiative provides Internet content filtering software to all families, schools and libraries in Australia.
- However, Coonan has already admitted that the Government's filter is not totally effective after a Melbourne schoolboy took just 30 minutes to crack the porn filtering software.
- At the time, Coonan said: "There is no silver bullet that can protect children online ... Sadly, just as a seatbelt will never prevent every fatal car crash, as the government has always maintained, no filter is foolproof. But a computer with a filter is infinitely safer than one without."
- The government has already piloted Web filtering technology three times in the past. Following the most recent trial, in 2005, Coonan acknowledged problems with the concept saying: "Each report has found significant problems with content filter products operating at the ISP-level ... The Australian trials have also found the effect on performance of the Internet by ISP filtering to be substantial and a lack of scalability of the filters to larger ISPs."
- The NetAlert -- Protecting Australian Families Online program will also see publicity campaigns stepped up, including a AU$22 million awareness scheme to "inform parents and carers of children about online safety issues and provide information about where they can go to receive support and assistance", and 10 new ACMA Internet safety officers who will visit schools to talk about online dangers.
- "We're trying to empower parents, to help kids maybe finding some aspects threatening in their lives, and overall making the Internet a benefit and not a negative," Coonan said today.
- Labor's communications spokesman Stephen Conroy has previously criticised the government's filtering plan and believes it won't protect Australian children from accessing inappropriate material online.
- The Opposition has its own plan to stop children accessing X-rated or illegal Web content, which it will bring in if elected. Speaking earlier this month, Conroy said: "We have said we support all government measures -- we support filters and we're proposing mandatory ISP filtering similar to that used in the UK."
Resistance fades as SaaS goes mainstream
Date: 10/19/2007
- Saugatuck has uncovered some dramatic changes in attitudes over the past year (the survey interviews were done in January and February this year and the results compared to similar interviews done over the same timeframe in 2006). Most notable:
- •Adoption is surging.
More than 26% of respondents worldwide have one or more SaaS solutions in place, up from 11% last year, and projected to reach 47% by the end of 2007
•Resistance is fading. Just 8% of companies said they had no plans to implement SaaS this year, down by more than two thirds from last year.
•Deployments are multiplying. Large enterprises that have adopted SaaS now have 3.4 applications deployed, with one in seven having more than 10 SaaS applications.
•Europe poised for breakout. The proportion of European companies planning to adopt SaaS has doubled this year to 34%, catching up fast on North America's 46% adoption rate. (That's good news by the way for prospective attendees at the upcoming OnDemand Europe conference in Amsterdam, May 30th - June 1st, where I'll be speaking).
- Saugatuck calls this an "adoption tsunami", and is predicting adoption rates of 60-75% by 2010. Speaking at last week's SaaScon conference, McNee repeated Saugatuck's view, which I first reported last month, that "We've already blown through the tipping point." He added: "This is not a one-trick pony. There is broad and deep adoption across many application areas."
- Saugatuck also makes some predictions about how adoption of SaaS will affect businesses, and that's the angle I'm most interested in exploring in today's webcast, aligning with the Work 2.0 theme of the series. Once mainstream adoption takes hold, McNee and his colleagues argue that SaaS will raise important business issues for users, such as:
- ·integrating SaaS workflows with enterprise business processes
·collaboration across business units or other enterprises
·customizing and personalizing business workflow
·utilizing built-in analytics and mix-and-matching data sources
What is peer-to-peer?
Date: 09/16/2007
- 1) Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session.Other models with which it might be contrasted include the client/server model and the master/slave model. In some cases, peer-to-peer communications is implemented by giving each communication node both server and client capabilities.In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.IBM's Advanced Peer-to-Peer Networking (APPN) is an example of a product that supports the peer-to-peer communication model.
- 2) On the Internet, peer-to-peer (referred to as P2P) is a type of transient Internet network that allows a group of computer users with the same networking program to connect with each other and directly access files from one another's hard drives. Napster and Gnutella are examples of this kind of peer-to-peer software. Major producers of content,including record companies, have shown their concern about what they consider illegal sharing of copyrighted content by suing some P2P users.Meanwhile, corporations are looking at the advantages of using P2P as a way for employees to share files without the expense involved in maintaining a centralized server and as a way for businesses to exchange information with each other directly.
- How Does Internet P2P Work?
The user must first download and execute a peer-to-peer networking program. After launching the program, the user enters the IP address of another computer belonging to the network. (Typically, the Web page where the user got the download will list several IP addresses as places to begin). Once the computer finds another network member on-line, it will connect to that user's connection (who has gotten their IP address from another user's connection and so on). Users can choose how many member connections to seek at one time and determine which files they wish to share or password protect.
Peer-to-peer network (wikipedia)
Date:09/16/2007
- A peer-to-peer (or "P2P") computer network exploits diverse connectivity between participants in a network and the cumulative bandwidth of network participants rather than conventional centralized resources where a relatively low number of servers provide the core value to a service or application. Peer-to-peer networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes.Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and real-time data, such as telephony traffic, s also passed using P2P technology.
- A pure peer-to-peer network does not have the notion of clients or servers, but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network. This model of network arrangement differs from the client-server model where communication is usually to and from a central server. A typical example for a non peer-to-peer file transfer is an FTP server where the client and server programs are quite distinct, and the clients initiate the download/uploads and the servers react to and satisfy these requests.
- The earliest peer-to-peer network in widespread use was the Usenet news server system, in which peers communicated with one another to propagate Usenet news articles over the entire Usenet network. Particularly in the earlier days of Usenet, UUCP was used to extend even beyond the Internet.However, the news server system also acted in a client-server form when individual users accessed a local news server to read and post articles. The same consideration applies to SMTP email in the sense that the core email relaying network of Mail transfer agents is a peer-to-peer network while the periphery of Mail user agents and their direct connections is client server.
- Some networks and channels such as Napster, OpenNAP and IRC server channels use a client-server structure for some tasks (e.g. searching) and a peer-to-peer structure for others. Networks such as Gnutella or Freenet use a peer-to-peer structure for all purposes, and are sometimes referred to as true peer-to-peer networks, although Gnutella is greatly facilitated by directory servers that inform peers of the network addresses of other peers.
Peer-to-peer architecture embodies one of the key technical concepts of the internet, described in the first internet Request for Comments, RFC 1, "Host Software" dated 7 April 1969. More recently, the concept has achieved recognition in the general public in the context of the absence of central indexing servers in architectures used for exchanging multimedia files.
- The concept of peer to peer is increasingly evolving to an expanded usage as the relational dynamic active in distributed networks, i.e. not just computer to computer, but human to human. Yochai Benkler has coined the term "commons-based peer production" to denote collaborative projects such as free software. Associated with peer production are the concept of peer governance (referring to the manner in which peer production projects are managed) and peer property (referring to the new type of licenses which recognize individual authorship but not exclusive property rights, such as the GNU General Public License and the Creative Commons License).
Classification of peer-to-peer networks
Date: 09/16/2007
- One possible classification of peer-to-peer networks is according to their degree of centralization:
- Pure peer-to-peer:
•Peers act as equals, merging the roles of clients and server
•There is no central server managing the network
•There is no central router
- Hybrid peer-to-peer:
•Has a central server that keeps information on peers and responds to requests for that information.
•Peers are responsible for hosting available resources (as the central server does not have them), for letting the central server know what resources they want to share, and for making its shareable resources available to peers that request it.
•Route terminals are used addresses, which are referenced by a set of indices to obtain an absolute address.
- Some examples of pure peer-to-peer application layer networks designed for file sharing are Gnutella and Freenet.
- Meanwhile some may also categorize peer-to-peer networks into the following categories:
•Centralized P2P network such as Napster
•Decentralized P2P network such as KaZaA
•Structured P2P network such as CAN
•Unstructured P2P network such as Gnutella
•Hybrid P2P network (Centralized and Decentralized) such as JXTA,GreenTea and Shwup
Advantages of peer-to-peer networks
Date: 09/16/2007
- An important goal in peer-to-peer networks is that all clients provide resources, including bandwidth, storage space, and computing power. Thus, as nodes arrive and demand on the system increases, the total capacity of the system also increases. This is not true of client-server architecture with a fixed set of servers, in which adding more clients could mean slower data transfer for all users.
- The distributed nature of peer-to-peer networks also increases robustness in case of failures by replicating data over multiple peers, and -- in pure P2P systems -- by enabling peers to find the data without relying on a centralized index server.In the latter case, there is no single point of failure in the system.
- When the term peer-to-peer was used to describe the Napster network,it implied that the peer protocol was important,but,in reality, the great achievement of Napster was the empowerment of the peers (i.e., the fringes of the network) in association with a central index, which made it fast and efficient to locate available content.The peer protocol was just a common way to achieve this.
- While the original Napster network was a P2P network the newest version of Napster has no connection to P2P networking at all. The modern day version of Napster is a subscription based service which allows you to download music files legally.
Coral Content Distribution Network
Date: 09/16/2007
- The Coral Content Distribution Network,sometimes called Coral Cache or Coral for short,is a free peer-to-peer content distribution network designed to mirror web content.Coral uses the bandwidth of volunteers to avoid slashdotting and to reduce the load on websites and other web content providers in general.This leverages the bandwidth of the participating Coral nodes as proxy servers,so it is similar to a distributed web proxy.
- To access a website through the Coral cache (and thus reduce the load on the site and use the Coral network instead),simply add .nyud.net to the hostname in the site's URL.
So,for example,http://en.wikipedia.org/wiki/Main_Page
becomes http://en.wikipedia.org.nyud.net/wiki/Main_Page.
The latter is known as a coralized link.Originally,the port was 8090,later 8080 was added in 2006 and now port 80 is used (the standard HTTP port).
- One of Coral's key goals is to avoid ever creating hot spots that might dissuade volunteers from running the software for fear of load spikes.It achieves this through an indexing abstraction called a distributed sloppy hash table (DSHT): DSHTs create self-organizing clusters of nodes that fetch information from each other to avoid communicating with more distant or heavily-loaded servers.
- The sloppy hash table refers to the fact that coral is made up of concentric rings of distributed hash tables (DHTs),each ring representing a wider and wider geographic range (or rather,ping range).The DHTs are composed of nodes all within some latency of each other (say a ring of nodes within 20 milliseconds of each other).It avoids hot spots (the'sloppy' part) by only continuing to query progressively larger sized rings if they are not overburdened — i.e.if there are many hits to the top-most two rings,it will just ping the close ones,when it reaches a hit that is overloaded it stops progressing upward.This therefore decreases hot spots while at the same time limiting the amount of global knowledge.The contributions of this work are the DSHT,which are avoiding hot spots (sloppy queries),and the concentric rings.
- Users who access the system are referred to a relatively close member of the system,which then finds the file on the coral DHT and forwards it to the user.
- The project has been in an open beta testing phase since March 2004.During beta testing,the Coral node network is hosted on PlanetLab,a large scale distributed research network of 400 servers,instead of third party volunteer systems.Of those 400 servers,about 275 are currently running Coral.The source code is freely available under the terms of the GNU GPL
