52' Plasma in Cube

I am trying to mount a remote filesystem hosted by a Linux machine.
The filesystem is properly exported and can be mounted by other computers.

I have tried entering the information into netinfo as instructed by:

http://deaddog.duch.udel.edu/~frey/darwin/archive/DarwinAndNFS.pdf

I have tried using mount -t nfs and tried mount_nfs.

Example:
mkdir /test1
sudo mount_nfs remotehost:/local /test1
cd /test1
bash:cd: /test1: Operation not permitted

In all cases, the mount succeeds, but when trying to access the directory, I get Operation not permitted. I have used su to login as root with the same results.

Any help would be greatly appreciated.

NFS in insecure mode... only over teh vpnage.

In this project, we examined ways to help present/depict hierarchical (tree) information structures in order to help people understand them and access the data in them. The Treemap visualization technique developed by Ben Shneiderman and Brian Johnson at Maryland is a well-known technique for depicting hierarchies. It uses a rectangular, space-filling slice-and-dice technique to visualize objects in the different levels of a hierarchy. The area and color of each item corresponds to an attribute of the item as well.

The SunBurst technique is an alternative, space-filling visualization that uses a radial rather than a rectangular layout. In SunBurst, items in a hierarchy are laid out radially, with the top of the hierarchy at the center and deeper leves farther away from the center. The angle swept out by an item and its color correspond to some atttribute of the data. For instance, in a visualization of a file system, the angle may correspond to the file/directory size and the color may correspond to the file type. An example Sunburst display is shown below.

In one study, we compared use of SunBurst to use of a Treemap. We created two UNIX file/directory browser tools that use the Treemap and SunBurst visualization techniques, respectively. We then used the two tools in an experiment in which 60 students performed a series of typical file/directory-related tasks. We measured both correct task completion rates and time to complete the tasks.

Results of the study appear in a technical report and in an article in the International Journal of Human-Computer Studies, both listed above. In general, the participants preferred the Sunburst tool, primarily due to its more explicit portrayal of the hierarchy structure. We found that performance with the Treemap tool benefited when a participant used the Sunbust tool earlier, suggesting a learning effect. Performance with both tools, in terms of correct task completions and times, was relatively comparable on a "small" hierarchy consisting of about 500 files. Performance on a "large" hierarchy of about 3000 files favored the Sunburst, particularly when comparing initial uses of each tool.

In another research effort, we developed a series of techniques for helping viewers to examine the small, peripheral files that often appear in a SunBurst display when it shows many files. The three techniques we developed are called Angular Detail, Detail Inside and Detail Outside. All use smooth animation and a focus context display methodology to help present small files for close examination within the context of an overview of the entire hierarchy. An article at InfoVis 2000 and a technical report, both listed above, describe this research. To most clearly understand the techniques, view a 4-minute video that we prepared for the InfoVis 200 Conference. 40 megabyte MPEG video.

In If You Don’t Use Del.icio.us, You Will Now at TechCrunch, the venerable web 2.0 buzz site, shows a cluelessness that’s quite remarkable. I’ve already missed the WWW ticket give-away and don’t care since I’m speaking, but really Mike, could you be more web 1.0?

Cramming delicious bookmarks into a hierarchy kills all that’s good about the service. Admittedly, speed is sometimes an issue, but the power of del.icio.us is the (personal and global) folksonomy, rejection of explicit hierarchy, and popularity mechanisms, along with the networking aspects of shared links.

The data is in, and has been for years, browser based, hierarchical bookmarks don’t work. There’s a lot of innovation in this space, but the Flock originated embedding of delicious cloud bookmarks in the browser is not innovative, it’s commercialization.

I mentioned some hacking I’m doing on the all.xml output from del.icio.us’ API in Firefox chrome. I’ve saved a static version an early rendering that supports browsing my many of my 1200 links at del.icio.us/andyed.

The image at the right shows the system state where analytics is being hovered. The coloring of the other keywords shows the co-occurence of the tag analytics with google, ajax, screencasts, blogging, and usability. The “weighted list” of the tag cloud shows the quantity of links with the tag, while the coloring of related tags shows the percent of urls with the second tag that co-occur.

This is a dual coding of the tag weight, but produces a nice aesthetic. In addition, the order of the tags is random currently. I’m working on packing more information into the view… there’s lots of it in the tag data, unlike a traditional hierarchy.

Anyway, have fun with the demo (Firefox only probably), click a tag to view the URLs, and send any good ideas my way for a true alternative to del.icio.us in the browser.

This analyzes the relationships between Andy's meta tags on del.icio.us.

Demo is here: http://surfmind.com/lab/linkdeli/demo_zoomer/index.html

This document covers a very specific, limited purpose, but one that meets a common need: preventing browser, mail, and other clients from complaining about the certificates installed on your server. Not covered is dealing with a commercial root certificate authority (CA). Instead, we will become our own root CA, and sign our own certificates.

(These procedures were developed using OpenSSL 0.9.6.)

Import private key and certificate into Java Key Store (JKS)

Apache Tomcat and many other Java applications expect to retrieve SSL/TLS certificates from a Java Key Store (JKS). Jave Virtual Machines usually come with keytool to help you create a new key store.

Keytool helps you to:

* create a new JKS with a new private key
* generate a Certificate Signung Request (CSR) for the private key in this JKS
* import a certificate that you received for this CSR into your JKS

Keytool does not let you import an existing private key for which you already have a certificate. So you need to do this yourself, here's how:

Let's assume you have a private key (key.pem) and a certificate (cert.pem

Toilet Snorkel
US Patent Issued In 1982

What exactly is this man doing? Communicating with his neighbors using his new Toilet Phone? Blowing up his Inflatable Toilet? Or is he simple blowing bubbles? Well the correct answer is None of the Above. This guy is using the new breath easy, Toilet Snorkel, formulated to provide a fresh air source during fires in high rise buildings.

In most fires, it's the smoke that will get you, and a source of fresh air can be a life saver. So our inventor designed a way to snake a snorkel through the zigs and zags of your toilet, so you can breath sewer air instead of smoke. Here's our question... couldn't he have, just as easily, invented the Faucet Snorkel instead?

IO-Warrior - The "Universal" for USB

Do you know the situation where all you want to do is connect some very simple
electronics to a computer, like a couple relais, switches, or a small display, but the
computer has no parallel port or that port is in use by some other device?

Going to USB for such things so far meant you had to develop specific code for a
USB enabled microcontroller, going through hundreds of pages of documentation,
getting the necessary development system, and finally having to develop a driver
for the thing. No more!

Simple to use

IO-Warrior does answer many of these requirements with an off the shelf solution.
IO-Warrior 40 does have 32 generic I/O pins, IO-Warrior 24 has 16 I/O pins, IO-Warrior56
even offers 50 I/O pins.
The pins can be used for anything, every single one acting as either an input or
output as you want.

For things a bit more sophisticated than just setting or reading a port pin IO-Warrior supports the "special mode functions". A simple command tells IO-Warrior to
enable one of these special mode functions. It is then taking direct control of a couple
I/O pins needed to perform the specific function.

IO-Warrior 40 and 24 support the IIC bus, controlling an alphanumeric LCD and a
LED matrix with up to 8x32 LEDs. IO-Warrior 40 can also control a 8x8 switch
or button matrix and IO-Warrior 24 has a SPI and a decoder for infrared remote
control signals according to the RC5 format. IO-Warrior56 can also control the majority of
graphic display modules, control a 8x64 LED matrix, and its SPI and IIC are faster.

Getting control of IO-Warrior from your software is very simple. On Windows
(any version up from 98 or 2K) you can use any programming language to access
the libraries, including Visual Basic. For MacOS X support does not only
include a library but even goes so far to support access via AppleEvents. Want
FileMaker to open a cash drawer? Just a moment!

IO-Warrior 24PowerVampire is a chip optimized for devices that want to use the USB
primarily as a power source. Four dedicated control lines allow direct connection of power
management chips or high side power switches.

To simplify the process of getting your first prototypes up and running we do provide
starter kits for the chips (not available for IOW24PV). All the basic components and a
few additional ones for initial testing are on the starterkit PCBs.
