GOVCOM.ORG: "A Narrative of the Software Project, IssueAtlas.net."  Richard Rogers does interesting work on mapping people and ideas on the internet.  This project is funded by the Soros Open Society Institute with OneWorld.net support.  5:10:56 PM  permalink  

Keyword Density Analyzer: "Keyword density is the ratio of a keyword or keyphrase to the total words (depth) on a page. Keyword density is a critical aspect of search engine optimization. To rank highly, your keyword density must not be too high or too low. A density of 1% to 7% is generally considered good."  I've been told this metric is important in knowledge discovery tools, implemented in many products, and this site allows a place to play with it.  4:57:03 PM  permalink  

Blogs As Instruments For Effective PR:  "Ask me to write music and I will run away.  Give me a band and I will sing now."  From an interesting blog.  3:19:51 PM  permalink  

Inxight Star Tree viewer: Inxight does KM through discovery and categorization.  The Star Tree viewer is their way of representing what's been found.  The free download was recommended to me as a way of sampling the technology.  3:17:01 PM  permalink

Plone Opens Up Web Publishing:  eWeek test says "We found Plone, which can be downloaded at http://www.plone.org, to be an excellent system for creating and managing collaborative portals or Web sites or for building corporate intranet pages. It proved to be much more capable and flexible than the competing PHP-Nuke. And Plone --which runs on Linux, Mac OS X and Windows--is quite possibly the most easily deployed server application we've ever seen, open-source or commercial.

However, although Plone is consistently referenced on its site and in its documentation as a content management application, don't expect to use it like a high-end Web content management system such as those from Vignette Corp. and Documentum Inc. For high-level Web site content management implementations, Bricolage is a better open-source alternative. "

Economist.com | Holographic data storage: Review of issues and prospects for products in 2004; several write-once announced at 200-500 GB.  "Theoretical calculations suggest that it will be possible to use holographic techniques to store a terabyte (1,000 gigabytes) of data on a CD-sized disk. Today's DVDs, by comparison, have a storage capacity of less than 20 gigabytes.

Moreover, holographic techniques permit the retrieval of data at speeds not possible with current storage methods. Transfer rates of a billion bits a second (at least 60 times faster than current DVDs) have already been demonstrated in the laboratory. Such fast access times are possible because the laser beams that are central to holographic technology can be moved rapidly, without inertia, unlike the components of a conventional disk drive. .. The challenge is to find the right recording material—a photosensitive substance that is both stable and cheap enough to use commercially. ..

searching a holographic store for a specific set of data is simple. Just as shining the appropriate reference beam produces a replica of the original data beam, so shining the appropriate data beam produces a replica of the reference beam. A beam that carries part of the original data will produce a weaker replica reference beam, making it possible to locate all the files that contain a particular set of data by shining in a beam containing that set and looking at the reference beams that come out. The intensity of each emergent beam indicates the degree to which the data stored in the file producing it match the target. Somebody sifting through a huge database could thus be directed rapidly to the best matches.  With the growing commercial interest in data-mining—which involves sifting through vast amounts of information in order to find useful relationships—this aspect of holographic memory is extremely attractive.

Stats on giving: "The richest 5 percent of households (those with an adjusted gross income of $140,000 or more) contribute 40 percent or $61 billion of the $152 billion a year given by individuals. Similarly, the 2 percent of estates valued at $3 million or more made 75 percent or $12 billion of the $16 billion in charitable bequests"  5:14:59 PM  permalink

Town agrees to repair shrine, pay victims:  Amusing story of how a local battle was defused.  "by Saturday, at least in Tuz Khurmatu, the situation was relatively calm, said [US Army Capt.] Swenson. He met with religious leaders that evening and arranged what would turn into a marathon negotiation session on Sunday in the sea-foam green ornate office of the town mayor, a Kurd.   Sweating in his fatigues and presiding over the room from the mayor's desk -- the mayor at his left, an outwardly patient Swenson cajoled the men into drafting and signing a document condemning the destruction of the shrine and apologizing for the deaths on Friday. Swenson meant to come out of this meeting with a written agreement and it was going to be honored. ..

"I will never run for city council," said Swenson, gripping the bridge of his nose and squinting his eyes with frustration and fatigue. "When I get home, I am going to have a beer and then fly to Australia for two weeks and not see anyone." When the meeting closed -- more than five hours after it started, with none of the assembled showing any signs of wanting to leave the room as they chatted and embraced and mopped sweat from their brow -- the young tank commander sighed. "Nobody trained us for this," he said."

GnoPhone, by linux support services: "Gnophone is an open source internet telephone that allows you to make calls to other GnoPhone users or to an Asterisk PBX Gateway. It supports a fully featured web interface allowing you to participate in various discussion groups. It also supports the full rate GSM codec for great quality that doesn't require very high bandwidth."  10:49:59 PM  permalink  

Digium - A Linux Telephony Company: "Digum offers a growing line up of telephony interface devices for the Linux platform. These devices share innovative design and small form factors, making them ideal for high density solutions. Combined with the Asterisk PBX software, these cards provide an interface to traditional telephony equipment, such as channel banks and provider T1 lines. Asterisk can extend the capabilities of the phone network, by acting as a bridge traditional telephony systems and Voice over IP equipment." These include T1/E1, FXO, and FXS cards for Linux computers.  10:45:17 PM  permalink  

Asterisk - The Open Source Linux PBX: "Asterisk is a complete PBX in software. It runs on Linux and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in three protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware. Asterisk provides Voicemail services with Directory, Call Conferencing, Interactive Voice Response, Call Queuing. It has support for three-way calling, caller ID services, ADSI, SIP and H.323 (as both client and gateway)."  10:43:18 PM  permalink  

Iraqis Log On to Voice Chat: "Today, in Baghdad's Internet cafés, it's not unusual to see many people sporting headsets and yakking away with someone across the world using IM software from Yahoo, or Microsoft's MSN Messenger program, according to Ala'a Harif, lead system administrator for SCIS. At peak times, the traffic from online voice chatters can almost completely tie up the government-run ISP's limited network bandwidth, says Harif.

While the technology isn't perfect, the economics of voice-over IM make it attractive for users in Iraq. Internet cafes in Baghdad charge around $1 per hour for connect time, versus a going rate of about $1 per minute for long distance telephone service. "

SIPhones: MP3 and Lindows founder sells SIP enabled phones for $129 a pair.  "The technology is also being built more deeply into PCs, as companies begin to add more advanced voice services into applications such as instant messaging. Microsoft's decision to add SIP support into the latest versions of its Windows XP operating system has made it much easier to perform Net calls using a basic PC, although customers still must sign up for another company's services."  Basic info available, with FAQs: "SIPphone users can dial 800 numbers and if they have a calling card which uses an 800 number, they can use that to call long distance numbers.

Dueling Timelines in Iraq (washingtonpost.com): "There aren't enough troops, there aren't enough police and there aren't enough contributions from countries with competent militaries. In Karbala, a city in southern Iraq where occupation has been fairly successful, 1,000 Marines are about to withdraw in favor of 455 Bulgarian troops. But the Bulgarians have no intention of assuming the civil administration functions the Marines have been carrying out, as the Wall Street Journal reported Friday, and a civilian team that was supposed to deploy there hasn't even been named. Given the stakes, and the potential for new problems, this kind of ragged, improvised, resource-poor effort is inexcusable and incomprehensible. "  12:27:07 AM  permalink
