On the off chance you’re not already familiar with YSlow, it is used to analyze Web pages against a set of best practices. YSlow crawls the DOM of a page, gets information about all of the page’s components and then generates a grade for each of the 23 performance rules. YSlow has extensions for Firefox and Chrome, and has bookmarklets for Opera, Safari and mobile devices.

YSlow project lead Marcel Duran says that developers are “encouraged to use the source code, learn how it works, fork it to make your own projects and enhance it with new rules, features and whatever will improve this tool we all love.”

The project is entirely written in JavaScript, HTML and CSS so it should be pretty easy for interested Web developers to jump in and contribute. If you’re interested in contributing to YSlow upstream, Duran says to follow the development tree rather than the stable tree.

YSlow’s GitHub repo was announced late last week, but already has 44 forks and 538 watchers. It’ll be interesting to see how it evolves now that Yahoo is throwing open the doors to community contributions.

The latest update may be a series of accusations from the corporate targeting its biggest competitor, Juniper Networks, and claiming that the latter can’t live up to its customers’ expectations.

“Juniper is “leaving customers and partners disappointed,” said Rob Lloyd, Cisco’s government vice chairman of operations. “We suppose we’d like to be a trifle additional aggressive in calling out missed guarantees and missed expectations.”

Juniper rejected these claims. Ray Mota, managing partner of ACG analysis, noted this is often a proof that chief government John Chambers is putting some pressure on execs before an analysts meeting on Tuesday. They “got the message,” he said.

Cisco and Juniper are competing with one another within the networking area for over a decade, and each them had some recent developments.

Juniper, for one, landed a brand new consumer, saying that Latin on-line media company Terra has switched to its technology. Networks QFX3500 Switches can soon be introduced to Terra’s datacenter across Miami and Porto Alegre, Brazil, to setup a QFabric network.

Cisco conjointly had a stimulating development not too earlier. Back at VMworld 2011 the corporate introduced Virtual Extensible LAN, ensuing generation networking protocol that’s designed for enterprise-scale virtualized environments. Soni Jiadani, senior vice chairman for Cisco talked regarding the new providing and gave us an insight into Cisco’s goals throughout her visit at theCube.

The lawsuit was filed Thursday in U.S. District Court for the Northern District of California, with a redacted copy of the case made publicly available Friday night. The lawsuit involves four Apple patents for technology that allows users to touch a phone number on a Web page to dial the number, word placement, Siri voice recognition and unified search, and the ability to unlock a smartphone by sliding an image from one location to another.

“Sales of the Galaxy Nexus during this litigation will cause irreparable harm to Apple,” the company said in the lawsuit. “The smartphone market is at a critical juncture, as the overwhelming majority of consumers move to smartphones, and the consumers’ long-term preferences and purchases may be determined to a great extent by the operating system on their first smartphone.” The importance of that initial purchase “is precisely why Samsung copies Apple’s products and incorporates Apple’s patented features, i.e., in order to lure crucial first-time purchasers away from Apple.”

Samsung’s decision to sell the Galaxy Nexus in the U.S. “is all the more egregious considering that Samsung did so in the face of this Court’s prior determination that Samsung’s earlier devices likely infringe certain Apple patents and that sales of such devices would likely cause Apple ‘to lose market share to Samsung’ that ‘could support a finding of irreparable harm’,” the latest lawsuit says.

Google and Samsung in October of last year unveiled the Galaxy Nexus, which runs Ice Cream Sandwich, the latest version of the Android operating system. The Apple lawsuit specifically targets Ice Cream Sandwich “with its interactive features” in the lawsuit, contending that Galaxy Nexus sales will mean that “Apple loses not only market share in the smartphone market, but also an untold number of sales in the broader mobile device market.”

Besides losing potential iPhone customers to the Galaxy Nexus, Apple will also suffer “incalculable” lost sales for iMacs, Macbooks and Apple TVs, the company contends. Further, Apple will be deprived of revenue it would have made through the iTunes store for both digital media and apps sales.

Apple has filed lawsuits against Samsung around the world, claiming that Samsung products including smartphones and tablets violate numerous Apple patents. Apple has been granted injunctions in a number of the cases, with judges ordering Samsung to stop selling specific products, as well as requiring the company to make changes to its products. A German judge ruled last week that changes Samsung Electronics has made to the Galaxy Tab 10.1N are enough that Apple’s intellectual property rights are no longer being infringed with that product. However, another judge in a separate German court ruled that Samsung can continue to sell the Galaxy Nexus in Germany.

Apple contends in the new U.S. lawsuit that it “has been forced to relentlessly pursue Samsung all over the world” and “yet while these cases progress — even after this Court found Apple likely to succeed on its infringement claims against prior Samsung devices — Samsung continues to launch infringing copycat products with impunity, all with the assumption that courts, including this court, will not stop Samsung before the gain to Samsung, and harm to Apple, is virtually irreversible.”

Representatives of Samsung could not immediately be reached to comment about the lawsuit. The company has, however, continued to defend itself against the lawsuits Apple has filed worldwide.

The data center was built for an Indian company, Tulip Telecom, which will make physical data center space available for clients. It will also provide cloud infrastructure services using IBM systems.

Mega-sized data centers are becoming increasing commonplace but this facility in Bangalore is different in one key respect: it’s vertical.

In the U.S., many large data centers are built in relatively rural areas that allow single story, mall-style construction that stretch over multiple acres. That approach doesn’t work in India, where land and space is at a premium, said Steve Sams, vice president for IBM global site and facility services. “High quality land in good locations is precious,” he said.

The first three floors are shared space. There are also four five-story towers where the data center facilities will be located. Each floor will have approximately 10,000 square feet of raised floor space built in modular style, or about 200,000 square feet of raised floor space in total. There will be two to three data centers on each floor, Sams said.

The facility will be able to support 100 megawatts, which puts it among the largest facilities in the world. It is located in one of the better areas in India for power reliability and is connected to two different grids, said Sams.

The facility has multiple levels of security , including an intelligent camera system with 1,500 cameras that can track a visitor throughout the facility, said Sams.

Sams said the data center will have a PUE (power usage effectiveness) of 1.5. PUE is the ratio of total facility power, including everything from the cooling systems, UPS, and lighting, to IT equipment power, the load associated with all IT equipment, the servers and storage .

The building that houses the data center was a shell for an uncompleted project within a business park. Work began in March last year.

The demand for data center space in India is expected to more than double over the next four years, according to Gartner. It said the market is expected to reach $609 million this year and rise to $1.3 billion through 2016.

Data centers are getting gigantic. CyrusOne, for instance, announced last fall that it purchased a 40-acre parcel in Chandler, Ariz., to build a 1 million- squar-foot data center with 110 megawatts of power capacity.

The National Security Agency is building a 1 million-square-foot data center in Salt Lake City at a cost of $1.2 billion.

China is building a cloud computing complex that’s expected to have some 6.2 million square feet of buildings, with 646,000 square feet of data center space rising to more than a million. China is experiencing, overall, a data center boom .

Linex, a Florida company that licenses wireless technologies, additionally filed a lawsuit within the U.S. District Court within the District of Delaware against constant corporations. In that suit it’s posing for financial damages for the violation of its patents.

The patents concern house diversity and coding, spread-spectrum antenna and technique, that uses multiple transmitter antennas and multiple receiving antennas to enhance a signal’s reliability, and multiple-input multiple-output unfold spectrum system and technique, that uses multiple antennas to maximise a wireless signal indoors.

Aruba announced the deal on Thursday because it reported money results for its 1st fiscal quarter ended Oct. 31. Pending regulatory approvals, Aruba expects the acquisition to shut throughout the second quarter of its 2012 fiscal year, that ends Jan. 31.

The acquisition of privately held Avenda, that the businesses didn’t disclose money terms, is meant primarily to assist serve enterprises that wish to let their workers bring their own smartphones and tablets to figure. to securelyundly} do so, employers have to be compelled to make sure that those devices are secure and go with enterprise policies.

Avenda sells an authentication and authorization platform, referred to as eTIPS, that features a server and a collection of applications. With that technology, Aruba said it’ll be ready to extend its own MOVE access management design to any or all access varieties and alternative vendors’ network gear. MOVE will establish users, device varieties, applications and locations, and apply network access policies using that data.

Avenda’s technology additionally includes regionally deployed or cloud-based software to create it easier for users to attach their mobile devices to secure Wi-Fi networks while not facilitate from the IT department. The software works on several Windows, Mac OS, Apple iOS and Google Android consumer systems.

Aruba plans to carry a conference decision concerning the acquisition for media on Friday at seven a.m. Pacific Time. Aruba is predicated in Sunnyvale, California, and Avenda in nearby Santa Clara.

For its fiscal 1st quarter, Aruba reported revenue of US$119.4 million, up forty four % from a year earlier, however a internet loss of $500,000, or roughly break-even. In last year’s 1st quarter, the corporate had posted a profit of $2.1 million, or $0.02 per share.

For the quarter ended Oct. 29, Cisco reported revenue of US$11.3 billion, up 4.7 percent from a year earlier, and net income of $1.8 billion or $0.33 per share. Earnings per share fell 2.9 percent from the year earlier.

Not counting certain one-time items, Cisco had net income of $2.3 billion or $0.43. The results were in line with the consensus of expectations from analysts polled by Thomson Financial, who forecast earnings of $0.39 per share on revenue of $11.02 billion.

The report was the first since Cisco set a new long-term growth forecast at a financial analyst conference in September. The company now expects between 5 percent and 7 percent annual revenue gains over the next three years, following several quarters of disappointing results and a major reorganization. It expects earnings per share to increase between 7 percent and 9 percent per year.

In a press release on Wednesday, CEO John Chambers said a majority of the company’s reorganization was complete.

In its fiscal fourth-quarter report released in August, Cisco had posted a drop of more than one third in net income and an increase of only 3.3 percent in revenue from the year-earlier quarter.

Since early this year, the company has moved to sharpen its focus on five key areas of its business; core routing and switching, collaboration, data-center virtualization, video, and tying these elements together in an overall architecture.

At yesterday’s Security Standard conference in Boston, executives outlined the interoperability between Cisco’s Network Admission Control (NAC) and Microsoft’s Network Access Protection (NAP), making good on a partnership that was announced in October 2004.

A newly released downloadable white paper details how both NAC and NAP will work together for security policy enforcement and health assessment as part of a single architecture. The paper also details how to embed Cisco’s network infrastructure with Microsoft’s Windows Vista desktop operating system and future versions of the OS server called Longhorn.

The two powerhouse vendors also released a roadmap for bringing the NAC and NAP combination to market, with beta programs scheduled for later this year. Once Longhorn becomes available in late 2007, users will be able to deploy the Cisco/Microsoft solution. As part of the pairing, Cisco and Microsoft have cross-licensed their NAC and NAP protocols to ensure interoperability.

Yankee Group vice president Zeus Kerravala said the long-expected pairing gives users flexibility in their network access choices. Since Microsoft NAP will be desktop focused and Cisco NAC is network focused, there will be no need for a string of smaller in-line appliances to achieve comprehensive
