So what should you do if you want to get rid of your Xbox 360 but you don’t want your personal information compromised? Podhradsky recommends detaching your 360’s hard drive, hooking it up to your computer, and using a sanitization program like Darik’s Boot & Nuke to wipe everything out. Just reformatting the system isn’t enough.

DBAN is a self-contained boot disk that automatically deletes the contents of any hard disk that it can detect. This method can help prevent identity theft before recycling a computer. It is also a solution commonly used to remove viruses and spyware from Microsoft Windows installations.
DBAN prevents all known techniques of hard disk forensic analysis. It does not provide users with a proof of erasure, such as an audit-ready erasure report.
Professional data erasure tools are recommended for company and organizational users. For secure data erasure with audit-ready reporting, contact Blancco or download a free evaluation license.

The foremost tool for writing scalable style sheets is the “em” unit, and it therefore goes on top of the list of guidelines that we will compile throughout this chapter: use ems to make scalable style sheets. Named after the letter “M”, the em unit has a long-standing tradition in typography where it has been used to measure horizontal widths. For example, the long dash often found in American texts (–) is known as “em-dash” since it historically has had the same width as the letter “M”. Its narrower cousin (-), often found in European texts is similarly referred to as “en-dash”.
The meaning of “em” has changed over the years. Not all fonts have the letter “M” in them (for example Chinese), but all fonts have a height. The term has therefore come to mean the height of the font – not the width of the letter “M”.
In CSS, the em unit is a general unit for measuring lenghts, for example page margins and padding around elements. You can use it both horizontally and vertically, and this shocks traditional typographers who always have used em exclusively for horizontal measurements. By extending the em unit to also work vertically, it has become a very powerful unit – so powerful that you seldom have to use other length units.
The new plastic display has a resolution of 1024×768 and is six inches across the diagonal, which is comparable to the Kindle and Nook. Because it’s made of plastic and not glass, though, the LG display is half the weight (14g) and 30% thinner (0.7mm) than a comparable, glass e-ink panel. Existing e-book readers need to be thick (and heavy) to protect the glass display, but LG is promising that its display is a lot more rugged. The press release says that the plastic display survives repeated 1.5-meter drop tests and break/scratch tests with a small hammer, and that it’s flexible up to 40 degrees from the mid point.

According to LG, the first plastic display-toting e-readers are expected to emerge in Europe “at the beginning of next month,” with the US presumably following swiftly after.
The Ultrium Linear Tape Open (LTO) specification, by far the most widely used tape spec in the industry, has a road map that takes tape out to 32TB per cartridge and up to 1.2GB/sec. throughput. “We’ve done a public demonstration of 29.5Gbits of data in a square inch of tape,” said Brian Truskowski, IBM’s general manager of system storage and networking. “We see a lot of headroom in terms of areal density.”

IETF explores new working group on identity management in the cloud.
A specification already exists for Simple Cloud Identity Management (SCIM) that is supported by security software vendors including Cisco, Courion, Ping Identity, UnboundID and SailPoint. SCIM also has support from key cloud vendors, including Salesforce, Google and VMware.

But private ownership can also have serious drawbacks. Transportation and communications services are essential inputs to a wide variety of industries. When the government helps a firm enter a transportation or communications market, it gives that firm a lasting advantage over potential competitors. If given free rein, a shrewd firm can leverage its government-supported dominance of a communications or transportation market to undermine competition and extract rents in adjacent markets that would otherwise be competitive. In the long run, this kind of rent-seeking behavior may prove dramatically more costly to consumers than would direct taxpayer support for the infrastructure.

Definition and Usage
The <link> tag defines the relationship between a document and an external resource.
The <link> tag is most used to link to style sheets.
Tips and Notes
Note: The <link> element must be embedded in the head section, but it can appear any number of times.
Differences Between HTML and XHTML
In HTML the <link> tag has no end tag.
In XHTML the <link> tag must be properly closed.

Bufferbloat, as you’ll recall from my 2011 predictions column, is the result of our misguided attempt to protect streaming applications (now 80 percent of Internet packets) by putting large memory buffers in modems, routers, network cards, and applications. These cascading buffers interfere with each other and with the flow control built into TCP from the very beginning, ultimately breaking that flow control, making things far worse than they’d be if all those buffers simply didn’t exist.
Bufferbloat was named by Jim Gettys of Bell Labs, who has become our chief defender against the scourge, attempting to coordinate what’s become a global response to the problem.
…
What AQM does is monitor the buffer, and signal the end points to slow down any time the buffer starts to fill, either due to that one transfer or competing transfers, by dropping or marking packets. So the buffer is kept (almost) empty, except when it is handling a burst of traffic. So the steady state latency of the buffer, rather than being the size of the buffer, is set by the size of the bursts in traffic. The size of the buffer becomes almost irrelevant.
