Personalizing PageRank

An article on CNet about a new search startup out of Stanford (link via Anil)

Kaltrix — “A stealth start-up out of Stanford University is hoping to raise the heat on one of the toughest problems in Web search–and possibly out-Google Google in the process.”

“Without discussing Kaltix’s plans publicly, the company’s founders have published research that claims to offer a way to compute search results nearly 1,000 times faster than what’s possible using current methods.”

Other interesting quotes from the article:

“Microsoft has publicized that it’s working on advancing MSN and desktop search. One area of development could be in integrating and personalizing search across Microsoft Office, Microsoft Outlook and the Web.”

“Search leader Google has also shown an interest in the area. Two years ago, it bought Outride, a spinoff from Xerox’s Palo Alto Research Center (PARC). Outride uses data-mining techniques, pattern recognition and natural-language semantic analysis to improve search results. But the acquisition has yet to produce visible results for Google.”

Visual Enterprise Search Tool

John sent me a link to KartOO Technology’s search engine and visualization UI that was “developed in Flash to present a friendly and clear visual interface while integrating the graphic charter of your company.”

You can see here what I think is a demo of the search and flash-based UI that’s actually meta-search engine of sorts that visually maps result-sets in the UI.

I wonder what their pricing mode is for these tools.

File Sync Tool for Unix and Windows

Unison seems to be a file-system agnostic replacement for the Robocopy tool found in the NT Resource Kit and others…

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.”

SMTP in a Spam-ridden world

CNET has a well researched article on whether this is the End of the road for SMTP in a world that is deluged with Spam.

Some interesting quotes…

“The flaws are so severe, some now believe, that the protocol that gave rise to the most significant explosion in written communication since Gutenberg may no longer be capable of serving its purpose in a world of con artists, pornographers, virus authors and unscrupulous spammers.”


“Some say rewriting SMTP from the ground up would be prohibitively difficult because of the protocol’s global user base, which is estimated to be in the hundreds of millions.”

“Proposals requiring a change to desktop mail software are even harder to deploy.”

CloudMark’s SpamNet has worked well for me, but I agree that the focus should be more at the server and protocol level.

Susan Sluizer, who co-authored the 1981 Mail Transport Protocol, SMTP’s direct predecessor, “counters this by suggesting two protocols–SMTP and a new one, with tighter authentication–could easily coexist, with e-mail applications supporting both side by side. In that way, people using one protocol would not be prevented from exchanging mail with those using another.”


“Microsoft, for example, advocates a change to the domain name system (DNS) that would make it harder for spammers to disguise their identity.”

“The “minor enhancement” Microsoft is preparing to release would let individuals, companies and other organizations publish the identification numbers of their mail servers in the DNS database.”

“Microsoft–with its Hotmail Web mail service, its MSN mail service, and others under its control–could single-handedly give such a system a sizeable implementation boost.”

“Harry Katz, program manager of Microsoft’s Exchange server group, warned that, in the rush to fix e-mail, the industry risks harming the openness that gave rise to the Internet’s success in the first place.”
