Besides many excellent technical papers presented at the P2P'09 conference in Seattle, I am particularly impressed with the 3 keynote speeches. Videos of these talks are now available on the Website (I was sitting at the back, therefore can't be found). Just like to blog a few lines here to remind me to not forget what were communicated:1. Ian Clark, creator of the Freenet Project, kicks off with

Content Addressable Network is an unique structured P2P system. Its topology is a d-dimensional torus. This overlay offer constant states (number of neighbours per nodes) and short hop counts (in terms of routing path length). Some works cited CAN as using hyper-cube space as its topology, which is a mistake. It is clearly stated in the original CAN paper that the space wrapped around, meaning

A Slashdot article shows links to an interesting article about the Hidden Cost of Privacy, which also caught Bruce Schieier's attention. As Bruce himself said, this article presents valid points, they are summarized as below:1. Too much paperworks in the "process" of protecting one's privacy could be so overwhelming that it has negative effects on increasing one's awareness of his own privacy.2.

The following information is for the TreeSet class in Java.As the name suggests, this class implements a tree datastructure, achieving the complexity of O(logN) with respects to add(), remove() and contains() methods. Take the last method, contains(k), where k is the search key as an example. The implementation of TreeSet will make sure this method return True or False within O(logN). Now if k

This note is for ones like me who moved from Redhat family to the Ubuntu community. It can be easily noted that the fonts used in Firefox and Thunderbird are very different.For Thunderbird, it can be changed in the Preferences/Fonts to match the default settings used in Fedora, for instance.For Firefox, the fix is not that simple.

It's more common to import pictures/diagrams into Latex.The Message Sequence Chart (msc) package in Latex is brilliant at drawing diagrams like protocols, UML message sequences. Unlike the algorithm package (alg2.sty), the MSC environment doesn't let you export its content to external files.The reason you may want to export these graphs is to include them into your Beamer slides, the environment

Starting with an article from the Register, condemning Bittorrent of starting the war on other network-friendly applications such as VoIP and killing the Internet.The P2P community responded keenly to the news. Some ponder the ease of NAT travelling this "improvement" would bring. Others turn absolutely furious against the article making mountain out of molehill. Later on (not much later to be

The 3.0 beta version of the most popular open source software, OpenOffice has been releasedrecently.  It remains the only document editor that I use to produce Word files.  The most significant added feature of this new release is the native support for Mac. Don't know how they did it, but it looks (and really is) just another cool Mac applications. It means no need to run X11 before using the

It is the very fist time I read an article in Slashdot mentioning Vietnam. My beloved country drew attention from Firefox, as an user discovered Trojan in the Vietnamese language pack for the infamous browser. The reporter, named Hai Nam Nguyen posted the news which was quickly confirmed by Firefox. A high-school friend of my is called Hai Nam Nguyen as well. He came to the national University,

 I've happened to bump in to this number 43 a number of times recently. Wikipedia did not have much information about this mysterious number. After all, it's not mathematicians who bring all the good stories. Here are my 2 cents.Most nerds must be familiar with number 42, as the answer for everything. The number that takes an alleged super computers years to come up with. Well, 43=42+1, doesn't

 Yes, just another story of Apple vs Microsoft. Blah, blah, blah ...Just to set the background, I was reading some stories with my newly acquired, blindly shining white Macbook, then I stumbled on the recent cover story on Business week, titled The Mac is in the Gray Flannel suit. It lays out an interesting and insightful discussion of the war between Mac and PC, from a business perspective. To

 Kraken were recently believed to be twice as big as the infamous Storm worm. There are debates on its estimated size, but it should have the army of at least several hundreds of thousands of zombie to take up such big headlines.  I blogged about Storm worm being a hot research topic not very long time ago. It found the way to some of the most prestigious conferences, NDSI for example. As

 Laugh of the day for me ! The creator of the Zeus malware added the End User License Agreement (EULA) to his intellectual property.  This is just a next, rational move for any emerging, profitable market of selling virus, malware online.  The basic restrictions are: no redistribution to any other business and no submission to anti-virus company.

PDFExpress is the online PDF validator tool that check if your PDF file is correctly formatted so that it can be published by IEEE CS and viewed online by IEEExplorer.  The tale is that the error that I got back says "Acrobat version is less than 5.0".

The recent USENIX conference NDSI has been slashdotted a lot. One very interesting paper describe how people pollute Stormnet, one of the biggest botnet, and bring it down to knees. One thing I learn from this paper is that the current Storm botnet is organized in a structured P2P overlay. It implements one of the very simple yet effective overlay called Kademlia.  So once infected, the bot

Sun Microsystem is currently removing the last hurdles in the run towards freeing its famous Java platform.The story reminds me of the days when I first used Linux.

Haven't got time to catch up with recent news, but so glad that I did eventually. In "recent" news, Google announced its new Google app engine.  It immediately sparked commotions not only in the Geek-world, but also in business world.  A great review of the new product can be found here. Long story short:1.

Well, another boring argument in favor of Wikipedia, you may guess. Right !Since Google's announcement of its Knowledge project called Knol (strangely being interpreted as an unit of knowledge), I've been observing discussion regarding the motivation behind this project and whether it's going to be a Wikipedia killer in the near future.

Bruce Schneier and Marcus Ranum posted their depressing conversation about our gloomy future in 10 years. Being both experts in security and software, they seem to share the same vision of the future. For the starter, Bruce pointed that in 10 year, if Moore's law still applies as it does today, our computing power would be about 100x. While technological capacity doubling every few years, the

Having knowledge of computer security does not mean you can make secure programs. It's especially true for Java, as many have taken Java for granted, assuming the underlying JVM would be doing its magic all the time and keeping all these problems at bay. Secure programming is a very practical skills which are essentially defined by good practices. And as usual, you have to learn new skills in

The media is doing every thing it could to blow the problem to a whole new scale, and literally tell the person who has these data how to "deal" with them.
