Here’s a very informative video on hacking the Cisco NAC from this company. You’re probably gonna wonder what’s a NAC. Well, Cisco explains it in detail.
Anyways, there’s an open source NAC project you might want to check it out.
Enjoy! Peace out.
Embedded R&D house eInfochips is offering an IP network camera reference design that runs Linux on a TI DaVinci RISC/DSP processor. The “IPNetCam” targets intelligent IP surveillance cameras, and is claimed to be among the first camera designs to support “dual streaming.”
The eInfochips IPNetCam offers a “dual mode encoding” feature said to be capable of supplying both JPEGs and differential video, streaming one JPEG and two MPEG-4 or H.264 image frames simultaneously. It is among the first cameras in the world to have this feature, eInfochips said.
It seems more and more companies are putting out Big Brother devices and softwares. Here’s the latest one, einfochips. The original article is here.
Haskell is not a who, but a what. Read here for more info.
This is a good read if you want to learn something in networking - “Configuring and Testing Border Gateway Protocol (BGP) on Basis of Cisco Hardware and Linux Gentoo with Quagga Package (Zebra).”
This is an agile development platform running on modified Knoppix Linux LiveCD composing of Subversion, Trac, CruiseControl and various other tools integrated together and is ready to run out-of-the-box. I haven’t tried it yet, but it sounds cool and you can download it from their website. Kudos to the ThoughtWorks team for offering this to the general public!
Check this out…pretty spiffy
The Nuvation design measures just 3.25 x 1.7 x 1.8 inches (79 x 43 x 47mm), yet it incorporates a full 300MHz ARM9 processor capable of running Linux or another embedded OS, according to the company. Compared to DSP-only cameras, this lets customers tune resolutions and data rates as required, fuse codecs, or run image analysis applications such as motion detection on the camera itself — consistent with security industry trends toward higher-quality “intelligent” cameras, the company says.
From the F-Spot Site:
F-Spot simplifies digital photography by providing intuitive tools to help you share, touch-up, find and organize your images.
This is a little vague, as it doesn’t mention my two favorite features. 1. Displaying a time line of photos (you can skid the bar over to 2001 and check out your photos from then). 2. Packs a useful image tagging system (create tags, select drag photos onto tags, see a photo as the icon for the tag)
Its a little past the new year now, however, I needed to get a FatPenguin shout out to my favorite Linux application of 2006: F-Spot personal photo management software. F-Spot may not be driving the web servers of the future or taking %s away from IEs user base, but it is one kick ass piece of photo management bliss.
Clean interface, intuitive, imports the photos directly from you camera, and quick basic editing functionality.
I found this article very helpful. I encounter this everyday at work. It’s a good read.
Kernel programmers wanted, as Greg Kroah-Hartman proclaims by giving his book to the public for free.
I want this book to help bring more people into the Linux kernel development fold. The act of building a customized kernel for your machine is one of the basic tasks needed to become a Linux kernel developer. The more people that try this out, and realize that there is not any real magic behind the whole Linux kernel process, the more people will be willing to jump in and help out in making the kernel the best that it can be.
You can download it from here. If you download it, you’ll be quizzed by Friday afternoon. So get studying! :)
Despite my avoidance of advertising I decided to run an add for Axigen mail server on my linux mail server document. I gave Axigen a try and was impressed by how easy and quick it was to get up and running. Also impressive was the large number of distributions they package for, including Gentoo!
It’s true, Apache + FastCGI is a horrible, horrible solution, unless your problem is “how can I waste my time on a dodgy server config?” in which case you shouldn’t be using the Intarweb while drunk.
I’m currently putting together a Rails, Mongrel, Apache configuration (maybe capistrano….). I was glad to find this article while looking how to use apache, with mod_proxy_balancer, and Mongrel instances.
The problem with resizing large images into thumbnails is the loss of quality due to decisions the resizing algorithms must make when removing pixels. I’ve been editing very large images to maintain a high level of quality for t-shirt printing, but creating the thumbnails (using the Gimp) has yielded poor results, like missing and blurred lines/edges.
I did some experimenting with a vector base image editing program called Inkscape. It has capabilities similar to Illustrator, Freehand, CorelDraw, or Xara X. It will allow me to design and export images to whatever size I need without quality loss, however, I tested importing the large images I created in the GIMP, exporting them to the thumbnail size and it produced crisp images. With the quality of exports I am comfortable continuing to create high dpi, resolution images and using Inkscape to produce the smaller images that will keep my eyes happy.
Occasionally you’ll find some criticism of Linux in the direction of “duplication” of efforts are wasted efforts. A good fraction of the time I don’t agree with what is considered duplications and it turns out it doesn’t matter if efforts are duplicated or not. It’s about freedom so if 20 people choose to write the exact same piece of software they are completely free to do so. The only time I do really care about duplication is when its something that I am working on, because I personally would rather contribute or write something unique in the OSS world.
Two benefits of having software choices are:
1. Similar applications / OSs / tools will have different features and feels. Pouring all efforts into a single project could lead to poor usability due to number of features and conflicting goals.
2. When things break, as they will always do from time to time, you can switch to alternatives and wait out the problems.
If your primarily concerned with productivity, know of and how to use various software, and use a “cutting edge” distro like Gentoo #2 has a nice glow.
Just yesterday I upgraded my profile, emerged my world, and had Gnome blow up in a wild display of sparks: a missing panel, broken icons, a dead mouse, and a message about lack of communications with the message bus (dbus). This was very annoying and I spent a few minutes trying to fix it. In the end, however, I just ditched it. I like fluxbox and was interested to give KDE a try (it had been a few years since I’ve last used it). So I had two great choices. I used fluxbox to keep working while I emerged KDE and when KDE was done toasting I plopped it on my plate, spread some jam, and continued to work away. I found out that I still don’t really like the feel of KDE, however, it will be just fine for me to use until the Gnome problem works its self out (as so often happens with Gentoo) or until I have some spare time to dive deeper into and fix the problems. Additionally I will probably find some more stuff I like, in KDE, that I would have never known about before. One cool thing that I have discovered is that it supports multiple monitors really well (setting multiple wallpapers and app transparency previews on each of the monitors wallpapers…. cool).
The same holds at the OS level. If you really screw up and your whole box becomes unbootable, throw in the live OS of your choice, mount your data, and continue to be productive until you have a chance to fix the problems.
Gentoo decided to throw me a hurdle when trying to `emerge rubygems` tonight:
The solution is to clear the RUBYOPT variable:
Howdy everyone. :) Due to the demand on the PS3 forums I am making some install videos of Yellow Dog Linux. Sorry about the slightly shaky footage, since I was installing and holding the camera at the same time.
They are a bunch of short videos instead of one long one since the process is taking a while and a lot of people wanted updates as it was happening.
I will be updating this with more videos, as well as YDL running on the PS3. I will also see if I can show it streaming videos from a Windows Vista PC.
