Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Huawei says it has “recently introduced…Beyond LTE technology, which significantly increases peak rates to 30Gbps – over 20 times faster than existing commercial LTE networks.”
via iTWire – Huawei claims 30Gbps wireless “beyond LTE”.
However it appears that Huawei is using much greater bandwidth. Its announcement goes on to say: “Key features include: innovative antenna structure [that] greatly improves performance and meets wideband requirements [and] next generation direct radio frequency technology [that] reduces costs and power consumption, and realises ultra broadband carrier aggregation.” (our italics).
The LTE-Advanced specification is for up to 100MHz of bandwidth, which need not be contiguous and up to 8×8 MIMO (eight transmit and eight receive antennas) and a maximum downstream bandwidth of 3.3Gbps.

The feature allows Web developers to specify that a single body of text should flow through certain regions of the page. For example, you could create several div elements in a specific arrangement and have the overflow text fill those consecutively. Another feature proposed by Adobe, called CSS Exclusions, makes it possible to have inline text automatically wrap and flow to conform with a specific shape.

The <span> tag is used to group inline-elements in a document.
The <span> tag provides no visual change by itself.
The <span> tag provides a way to add a hook to a part of a text or a part of a document.
When the text is hooked in a <span> element you can add styles to the content, or manipulate the content with for example JavaScript.
via HTML span tag.
From The SPAN Tag
Use span tags when you don’t want any changes to the layout other than exactly what you specify in the styles of the span. For example, if you use a <div> or <p> most browsers will add space around the element, because they are block elements.

From: Accel-Backed ScaleXtreme Takes Data Center Management To The Cloud
ScaleXtreme wants to do the same thing to data automation that Salesforce did to CRM. Replace million-dollar deployments that take months with a five minute download that can have a machine being managed from the cloud in five minutes. And instead of an upfront $1,500 licensing fee per machine, plus maintenance and upgrade fees, ScaleXtreme is shooting for something closer to $150 a year per machine. “This is a radically different model,” says Mulchandani, who started out as an enterprise IT sales guy. “You download the agent and you are done—no sales people, no Italian suits flying across the country.”
