noveltynoveltynovelt comments on IAMA 24yr old who wants to disconnect from society and live off-the-grid, self sufficiently, ala hermit-style kungfu. Any suggestions? Kevin Warwick - Home Page Set up Ubuntu 10.04 Server PV DomU at Xen 4.0 Dom0 (pvops 2.6.32.12 kernel) Dom0 on top of Ubuntu 10.04 Server « Xen Virtualization on Linux and Solaris The procedure bellow in general follows Thiago’s Martins submission [1] to xen-devel mailing list. However,sequence of steps has been changed and also option of pvops kernel build via make-kpkg was added , /dev/xen/evtchn device hard linked with with pvops kernel, git checkout procedure is more straight forward and one Change-set from xen-4.0-testing.hg back ported to Xen 4.0 to support grub2 notation ‘(hd0,1)’ specific for Ubuntu 10.04 aka Lucid Lynx. Several suggestions have been also made regarding to have libvirt ,virtinst and related packages to work with Xen 4.0 on 10.04 Server. With config bellow there is no need to touch /etc/modules at all. Option “userspace grant access device driver is set to” <*> to make virt-install handy at Xen guests installs cd /usr/src At this point creare grub2-fix.patch1 as raw content of
Self Organizing Map AI for P Introduction this article is about creating an app to cluster and search for related pictures. i got the basic idea from a Longhorn demo in which they showed similar functionality. in the demo, they selected an image of the sunset, and the program was able to search the other images on the hard drive and return similar images. there are other photo library applications that offer similar functionality. honestly ... i thought that was pretty cool, and wanted to have some idea how they might be doing that. internally, i do not know how they actually operate ... but this article will show one possibility. also writing this article to continue my AI training Kohonen SOM luckily there is a type of NN that works with unsupervised training. i'm guessing that it is the 2nd or 3rd most popular type of NN? anyways, that is my current understanding; here are some other articles i recommend 1) Grid Layout 2) Color Grouping 3) Blog Community (OUCH!) 4) Picture Similarity
Building A Virtual Cluster with Xen (Part One) Published on Thursday, 20 July 2006 21:00 Written by Angel de Vicente Hits: 126656 A step by step guide It is a common practice to have development and test servers for each production server, so that you can experiment with changes without the fear of breaking anything important, but this is usually not feasible with clusters. So how do you try that new version of your favorite program before committing it to the production cluster? Thanks to the Xen virtual machine monitor, you can create a number of virtual machines, all running simultaneously in your computer, install different operating systems in them, or just different configurations, and connect them via (virtual) network cards. This guide is the first of a series in which I give you detailed step-by-step instructions on how to build a virtual cluster with Xen. The goal is to start it simple and then add more complexity as we progress, so in this first guide I show you how to get do the basics: Figure One: Network Structure
generation5 - At the forefront of Artifici XenLinux kernel 2.6.34.7 aka Suse under Xen 4.0.1 on top of Ubuntu 10.10 Desktop « Xen Virtualization on Linux and Solaris Following post is a brief instruction of port 2.6.34.7 xenified aka Suse kernel to Ubuntu 10.10 desktop , to support Dom0 under Xen 4.0.1. Vanilla 2.6.34.7 gets patched via Andrew Lyon’s rebased patch set xen-patches-2.6.34-5.tar.bz2. Kernel configuration is similar kernel-xen config on Suse’s 11.3 . Xen back-end,evtchn,gntdev divices get loaded via /etc/init.d/xend at startup. Xen 4.0.1 and Libvirt 0.8.3 installations are just the same as in [1]. # cd /usr/src/xenLinux/ # wget Untar linux-2.6.34.7.tar.bz2 and apply patches. # cd /usr/src/xenLinux/ # bzcat linux-2.6.34.7.tar.bz2 | tar xf - # mkdir -p xen-patches-2.6.34-5 # cd xen-patches-2.6.34-5 # bzcat ../xen-patches-2.6.34-5.tar.bz2 | tar xf - # cd ..

ConceptNet What is ConceptNet? [top] ConceptNet is a freely available commonsense knowledgebase and natural-language-processing toolkit which supports many practical textual-reasoning tasks over real-world documents right out-of-the-box (without additional statistical training) including topic-jisting (e.g. a news article containing the concepts, “gun,” “convenience store,” “demand money” and “make getaway” might suggest the topics “robbery” and “crime”), affect-sensing (e.g. this email is sad and angry), analogy-making (e.g. The ConceptNet knowledgebase is a semantic network presently available in two versions: concise (200,000 assertions) and full (1.6 million assertions). ConceptNet is a unique resource in that it captures a wide range of commonsense concepts and relations, such as those found in the Cyc knowledgebase, yet this knowledge is structured not as a complex and intricate logical framework, but rather as a simple, easy-to-use semantic network, like WordNet.
