Shared Ethernet adapters (SEAs) can be used for IEEE 802.1Q VLAN tagging. However, once the SEA is in use, you cannot make changes to the VLANs on the trunk virtual Ethernet adapter without stopping the SEA. By using separate virtual adapters for each tagged VLAN, you can attach a new virtual adapter with its new VLAN to the SEA without any downtime. Retiring a VLAN from the SEA can be just as easy with a modular approach: one tagged VLAN per virtual adapter.

Are you looking to share access of your protected resources by becoming an OAuth service provider? This article describes how you can use IBM® WebSphere® Application Server (V7.0 and later) with Trust Association Interceptors (TAI) to accept OAuth tokens for authorizing calls from applications or web sites (consumer) to protected resources. TAIs make it possible to support OAuth alongside other token services, such as LTPA, while meeting WS-Security restrictions.

The open source Tripwire® is a file integrity checker package that has been around for years and, though I have used it many times on Linux® distributions, I have only recently got around to using it on AIX®. This is mainly due to the following:

* It is troublesome to compile using the gcc AIX version.
* I prefer using the AIX built-in audit service.

However, as there is now a Tripwire rpm for AIX, I use it for some of our AIX boxes. Tripwire does not provide a complete solution to intruder detection based on file changes, but coupled with running an AIX audit, it provides a firm security policy. Tripwire monitors for changes to files and directories on your system via the objects that you provide in the main policy file.

I mentioned some Linux tools that, while still included and functional in many Linux distributions, are actually considered deprecated and therefore should be phased out in favor of more modern replacements.

Specifically, the deprecated Linux networking commands in question are: arp, ifconfig, iptunnel, iwconfig, nameif, netstat, and route. These programs (except iwconfig) are included in the net-tools package that has been unmaintained for years. The functionality provided by several of these utilities has been reproduced and improved in the new iproute2 suite, primarily by using its new ip command.

So in February 2008, he all but stopped sending e-mail. He didn’t wipe out his inbox. In fact, he still checks e-mail daily — it takes him about two minutes per day; most messages are internal meeting notifications — and he still uses it for sensitive one-on-one conversations. But for the most part, when people write him, he answers via social media and suggests that they’d be better off chatting via Twitter, Google+, or on Connections, IBM’s internal social network. The idea is that if more of his communication is in the open, he’ll spend less time communicating.

OpenSocial is a set of common application programming interfaces (APIs) for web-based social network applications. OpenSocial consists of the Gadgets standard and the OpenSocial Data API providing access to the social graph by gadgets. With version 2.0 OpenSocial is moving towards being an Enterprise standard for building social applications.. aka

David House took his laptop to Mexico a little over a year ago, hoping to squeeze in some work between sightseeing, fishing, and laying on the beach. All went well, vacation- and work-wise, until the former MIT researcher landed in Chicago, where federal agents seized his laptop, kept it for nearly two months, and may have shared information on his hard drive with several government agencies.

They didn’t have a search warrant. They didn’t charge him with a crime. And there was nothing House could do about it.

House, 24, ran into what civil liberties advocates call the “Constitution-free zone’’ at US ports of entry, where courts have carved out broad exceptions to the Fourth Amendment’s protection against unreasonable searches and seizures. As long as they don’t use invasive techniques such as strip searches, government agents don’t need reasonable suspicion or probable cause to seize what they want - including laptops, a 2008 appeals court ruling held.

Wie das Nachrichtenmagazin “Der Spiegel” vorab berichtet, ermitteln Kölner Fahnder gegen einen Beamten der Bundespolizei aus Frankfurt am Main. Der Mann habe demnach seiner Tochter einen Trojaner auf den Rechner gespielt, um ihr Treiben im Internet zu überwachen. Die Tochter habe allerdings einen Freund aus der Hacker-Szene gehabt, dem die Spionage auffiel.

Um es dem neugierigen Vater heimzuzahlen, sei der Hacker in dessen Computer eingedrungen. Dort sah er, dass der Polizist dienstliche Mails an seinen Privatrechner umgeleitet hatte. Das ebnete dem Hacker den Weg ins Innere der Bundespolizei. Als Folge des Angriffs musste der “Patras”-Server abgeschaltet werden, über den die Polizei Verdächtige observiert.

He said there was a high bar for something to be considered a human right. You have to deal with things like freedom from torture or freedom of conscience before you get to things like an internet connection.

Putting technology into this exalted category makes things difficult over time too, he says. Once, if you lacked a horse, it was hard to make a living. But if it was everyone's right to have a horse then it would be pretty silly today, he reasons.

It is better to talk about critical freedoms like freedom of speech and freedom of access to information which are not necessarily bound to any particular technology at any particular time.

Today’s Big Blue is the antithesis of Big Brother. It’s ‘Big Open’. A transparent, nimble, collaborative organization known more for listening and engaging customers than for dictating to them. While ironically, some say Apple now resembles Big Brother given their propensity for tight controls.

And that’s why IBM — not Apple — represents the future workplace.

While Apple has been wildly successful, IBM’s Social Business is much more attainable and sustainable than what Fortune’s Adam Lashinsky describes as Apple’s genius led, culture of fear. For the genius is always, as Benjamin Disraeli and later Peter Drucker predicted, succeeded by a “lieutenant of Marines” who understands the business but nothing else. So the company is only left with an innovation vacuum.

After their request was denied several times, the Church of Kopimism – which holds CTRL+C and CTRL+V as sacred symbols – is now approved by the authorities as an official religion. The Church hopes that its official status will remove the legal stigma that surrounds file-sharing.
