TheRegister: Core i7 bumped to 3.33GHz
by Rik Myslewski
Intel has speed-bumped its top-of-the-line Core i7 Extreme Edition processor, increasing its lead as the fastest desktop chip that the company has ever offered.
The new 45nm Core i7 975, based on the company's Nehalem architecture, clocks in at 3.33GHz. It includes 8MB of L3 Smart Cache running at its four cores' clock speed.
Dual QuickPath Interconnects (QPI) transfer data at 6.4GT/sec, and such performance-enhancing niceties as Intel's SpeedStep (EIST), Virtualization (VT), and Turbo Boost auto-overclocking technologies are all enabled.
Its core-clock multiplier is set at 25X - but it's unlocked, should you feel the need to experiment with a bit of straightforward overclocking.
The Core i7 975 slots into the now-second-class Core i7 965's price point, which is $999 in lots of 1,000 - although processors at this rarified level are rarely if ever sold in those amounts. You can find it today in retail packaging at sites such as NewEgg for $1,039 and Platinum Micro for $1,078.
But if that's too rich for your Meltdown-melted wallet, you might instead pick up a Core i7 920, which can be found at various outlets for well under $300. It takes well to overclocking, and an Intel spokesman told The Reg that it will "most definitely" remain available for the foreseeable future. ®
InfoWorld: UnboundID's free sync server aids migration from Sun directory
by John Fontana
Directory and identity start-up UnboundID has released a free tool for Sun users to help them add missing capabilities to their directories and migrate off the platform.
UnboundID Synchronization Server provides bi-directional sync that allows users to run in parallel the Sun Directory Server and the UnboundID Directory Server as part of an overall migration away from Sun.
Later this year, UnboundID will add synchronization for Active Directory (which Sun already provides for its directory) and database synchronization.
The Synchronization Server also includes a sophisticated replication feature that supports fractional, filtered, and partial replication between the two directories. The feature, which Sun's directory is lacking, lets users create directory instances designed for specific use-cases that contain only the data needed and not the entire contents of the master directory.
"We have provided a back-out mechanism so you can sync the changes in the old environment with the new environment or the changes in the new environment with the old environment," says Don Bowen, co-founder and vice president of marketing at UnboundID. If panic hits, Bowen says, users can cut back to their old directory system with assurances that changes, wherever they were made, are retained.
UnboundID's synchronization tool comes at a time when Sun is in transition, both with an impending acquisition by Oracle and with a majority of its user base on its aging version 5.2 directory platform. In addition, Oracle's own directory technology, which supports identity management and directory synchronization, overlaps with the Sun directory technology.
UnboundID Directory Server, which was launched in March, is based on the Lightweight Directory Access Protocol V3 and combines qualities found in directory and database technology to create an identity platform for large service providers and corporate networks.
The directory server is built around customizations to the OpenDS project, which was developed by the four former Sun employees who founded UnboundID.
The Synchronization Server includes real-time sync between the UnboundID and Sun directories, which lets companies run the two platforms in parallel and manage directory migration in a controlled fashion. The server also supports DN mapping, attribute mapping, and transformation. Users can modify both the directory information tree and the directory schema without scripting.
"Directory server migration is a great time to correct sins of the past," says Bowen. "In particular, addressing schema changes, attribute name changes, and object classes"
CNet: Yes, Twitter is revolutionary-just not in the way you think
by Caroline McCarthy
I thought Twitter hype had reached a fever pitch with the big Oprah appearance. Boy, was I ever wrong.
If it isn't Time magazine's "How Twitter Will Change the Way We Live" cover story, it's the widely-circulated Comedy Central clips of co-founder Biz Stone's April appearance on "The Colbert Report," or it's chairman Jack Dorsey, in New York for this week's Internet Week festivities, showing up in society-blog photos from the sidelines of a Diane von Furstenberg fashion show. (OMG!) When I was joking about Twitter's executives reaching pop-idol ubiquity, I didn't think it'd be this soon that they'd start to seem like a slightly older, slightly less puppy-faced set of Jonas Brothers. Twitter and its creators are unavoidable.
But there's something nobody's really saying about Twitter throughout all this: Not everyone is going to use this service. Far from it, in fact. Its mainstream impact could very well have nothing to do with TweetDeck, hashtags, or even the name "Twitter" itself.
The Business Insider did a nice by-the-numbers of exactly what Twitter's explosion amounts to: 60 percent of users quit after a month, ten percent account for 90 percent of all "tweets," et cetera. All these numbers point to one fact: Twitter is high-maintenance. Even if you're only using it to read the latest updates from a few publications and some of your favorite bands, you're still reading about them in short bites that flow in a relatively inefficient manner. Parsing the noise takes effort; participating in it takes even more.
Compare that to Facebook: you can create a static profile, check in every few days, get an e-mail alert when a former high school classmate has added you as a friend, and you're all set. There are loads of apps on the social network if you feel like playing a round of poker or pretending to turn your friends into vampires, but at its most basic level, it doesn't require much effort to stay active on Facebook. Not so with Twitter.
The company's executives seem to acknowledge that in order to reach those who won't get involved otherwise, Twitter has to think outside the 140-character box (er, stream) and get the news industry involved. These people who don't actively participate in Twitter-you know, the 60 percent who drop out after a month-are going to know Twitter as something that enhances the news they already read and watch.
"One thing that's missing from it is the editorial. I think a cohesive narrative around all these reports is missing," said Jack Dorsey at Internet Week's I Want Media panel on Wednesday, just a few hours before he was looking worthy of any gossip magazine's annual eligible bachelors list at that Diane von Furstenberg show. "Bringing journalistic integrity to this mass of messages happening in real time is still very important."
In other words, Twitter's executives realize that the product in and of itself doesn't suffice universally for a legitimate, lasting mainstream reach-namely, an impact on people who aren't going to use Twitter otherwise. There are already dozens of developer applications making it possible to customize and enhance the service. The company is now working actively with media outlets on what it calls the "creative API", integrations of Twitter into content like Current TV's news programming and MTV's forthcoming "It's On With Alexa Chung." That's the beginning of what Dorsey was alluding to on Wednesday.
As more media deals roll in, the question to explore is whether this will, paradoxically, dilute Twitter's reach (and potential for profits) as a company. Once something becomes a standard rather than a brand, it gets tougher for a single company to make money off it. Think about instant messaging: Millions of us use AIM, but AOL isn't getting any ad revenue from those of us who are using it on universal IM clients like Pidgin or Adium.
The Twitter guys have built a great product, and to their credit, I don't think any of them have ever gone on the record saying that they hope to turn all six or seven billion or however many people there are on the planet into active users. It's not that this "Twitter is revolutionary" talk isn't true. Twitter is revolutionary in the sense that it turned the world on to a whole new form of information consumption-real-time, public conversations, aggregated and searchable. But just like blogging or instant messaging, this is going to get bigger than a single brand or company.
Jack Dorsey said in the same event at Internet Week New York that "Twitter's a success for us when people stop talking about it." He's right. But that implies a few things: one, that the hype and wildfire adoption will die down; two, that Twitter will fade into the background as the mainstream starts to recognize it as something they see on TV news broadcasts rather than a nifty, trendy tool for informing the world what you're doing; and three, that as other innovative companies catch on, the "real-time streaming conversations" phenomenon will expand beyond this one microblogging service. Twitter's legacy may very well have the word "Twitter" left out of it.
For the 140-zillionth time, let's not get ahead of ourselves.
