Exploring New Nepomuk Features in Mandriva

Filed under
KDE
MDV

You have probably heard of Nepomuk, the semantic desktop technology we've been shipping for a while as part of the KDE Platform. However, so far, you may not have noticed it really doing very much useful for you. So what is this thing called Nepomuk, what can it do for us now and what will it bring us in the future? We asked two of the driving forces behind Nepomuk, Stéphane Laurière and Sebastian Trüg of Mandriva, to tell us about the real Nepomuk features that are already available in KDE software and those that have been introduced with Mandriva Linux 2010.

An overview of the current status

So, where are we at with Nepomuk now, compared to where we want to be? Stéphane explains that "Nepomuk initially aimed at two main achievements: 1) the ability to interlink data semantically on the desktop across the applications, 2) the ability to share semantic information with other desktops". The first is "getting mature from the infrastructure point of view" and he believes that Mandriva Linux 2010 gives a good insight into the improvements it can bring to the user, but much remains to be done. The design of the framework for the second main objective started only recently: "a workshop took place in Freiburg early November and resulted in a first draft of the Nepomuk Sharing Ontology, and in a set of sharing use cases". Ultimately, it should be possible to share semantic information everywhere from mobile handsets to enterprise servers so that "the sky's the limit".

Nepomuk is already there in ways that you hardly notice - when you tag an image in Dolphin that tag is also visible in Gwenview. Obvious right? Well of course, but that is Nepomuk in action behind the scenes.

    For the past few months, developers who publish their code on GitHub have been targeted in an attack campaign that uses a little-known but potent cyberespionage malware. The attacks started in January and consisted of malicious emails specifically crafted to attract the attention of developers, such as requests for help with development projects and offers of payment for custom programming jobs. The emails had .gz attachments that contained Word documents with malicious macro code attached. If allowed to execute, the macro code executed a PowerShell script that reached out to a remote server and downloaded a malware program known as Dimnie.

    When WikiLeaks founder Julian Assange disclosed earlier this month that his anti-secrecy group had obtained CIA tools for hacking into technology products made by U.S. companies, security engineers at Cisco Systems (CSCO.O) swung into action. The Wikileaks documents described how the Central Intelligence Agency had learned more than a year ago how to exploit flaws in Cisco's widely used Internet switches, which direct electronic traffic, to enable eavesdropping. Senior Cisco managers immediately reassigned staff from other projects to figure out how the CIA hacking tricks worked, so they could help customers patch their systems and prevent criminal hackers or spies from using the same methods, three employees told Reuters on condition of anonymity.
  • NTPsec: a Secure, Hardened NTP Implementation
    Network time synchronization—aligning your computer's clock to the same Universal Coordinated Time (UTC) that everyone else is using—is both necessary and a hard problem. Many internet protocols rely on being able to exchange UTC timestamps accurate to small tolerances, but the clock crystal in your computer drifts (its frequency varies by temperature), so it needs occasional adjustments. That's where life gets complicated. Sure, you can get another computer to tell you what time it thinks it is, but if you don't know how long that packet took to get to you, the report isn't very useful. On top of that, its clock might be broken—or lying. To get anywhere, you need to exchange packets with several computers that allow you to compare your notion of UTC with theirs, estimate network delays, apply statistical cluster analysis to the resulting inputs to get a plausible approximation of real UTC, and then adjust your local clock to it. Generally speaking, you can get sustained accuracy to on the close order of 10 milliseconds this way, although asymmetrical routing delays can make it much worse if you're in a bad neighborhood of the internet.

    I assume that every permutation of scams will eventually be tried; it is interesting that the initial ones preyed on people's avarice and dishonesty: "I will transfer millions to your bank account, then you share with me" - with subsequent scams appealing to another demographic: "I want to donate a large sum to your religious charity" - to perhaps capture a more virtuous but still credulous lot. Where will it end ?
