"In other words, You can either have a concrete API that has specific JavaScript syntax for each sensor's properties and events, or you can have a generic, dispatch-like API that is tied to a very specific ontology, vocabulary or list of acceptable values that can be used as parameters. Considering the vast range of sensors that might be included in the foreseeable future, the size of the API could be quite large and complex; alternatively, the API could be simple and the ontology could be complex." - Vlado Handziski

"I’d like to offer a little history lesson to the Wireless M-Bus folk. Wireless is different from wired. It involves adding security, connection methodologies, and both topology and power management. It took the 802.11 standards group around 13 years to go from their starting point of translating a wired 802.3 connection to the first reliable and interoperable wireless one in the 802.11b specification. Wireless is not a small step. If you think that it is and decide to ignore the evidence of history, you run the risk of making a catastrophic mistake that has major ramifications for the future costs of your country’s energy usage." - Vlado Handziski

This has the potential to replace a lot of the functionality that I liked on Friend Feed. They only need to start filtering the entries based on the Google Friend Connect and add a feed from the collected entries on the Google Profile page. Here is mine: http://www.google.com/profile... - Vlado Handziski from Bookmarklet

Well, the feed thing is already available via the API: http://www.google.com/sidewik... - Vlado Handziski

It is interesting to see parallels between the FriendFeed API 2 and the Sidewiki API. For example the inclusion of profile snippet in the feed using "sidewiki:desc" and "description?" in FF API2. - Vlado Handziski

"Today, Aptana is proud to announce that Pydev and Pydev Extensions have become a single plugin, with all the available contents open source (and freely available for anyone) in the 1.5.0 release (it's the same as 1.4.8 but with all the code open source)." - Vlado Handziski

" The construction is one of an astonishing collection of paper objects folded by Dr. David Huffman, a former professor of computer science at the University of California, Santa Cruz, and a pioneer in computational origami, an emerging field with an improbable name but surprisingly practical applications." - Vlado Handziski from Bookmarklet

"Fascinating and elegant shapes may be folded from a single planar sheet of material without stretching, tearing or cutting, if one incorporates curved folds into the design. We present an optimizationbased computational framework for design and digital reconstruction of surfaces which can be produced by curved folding. " - Vlado Handziski from Bookmarklet

Just returned from a nice bike tour to the bell tower of the Church of the Redeemer, Sacrow (http://en.wikipedia.org/wiki...) where in 1897 Prof. Adolf Slaby performed one of the the first experiments with Wireless Telegraphy in Germany - Vlado Handziski

Here is an excerpt (in German) from his description of the experiments (http://www.ars-sacrow.de/index...) I like how he hypothesizes about the sources of interference and how he played with the antenna wire - Vlado Handziski

"Yesterday I did a bunch of experiments on three cloud-computing services. Partly this was just to get some actual hands-on experience with each one. Partly it was to calibrate expectations with respect to I/O performance, for New Job which is approaching quickly. On each one, I set up a small instance using Fedora/CentOS (would have used RHEL except that it incurs extra licensing charges). Then I installed gcc, which wasn’t in any of the base images, compiled iozone, and ran some very basic I/O tests. In each case I tested with both one and four I/O threads. Here are some observations." - Vlado Handziski

"REST over HTTP is the most common (almost only) implementation of the REST architectural style - to the point REST over HTTP is synonymous with REST. I would say most of the people who think of REST in CRUD terms, think about mapping of the HTTP verbs." - Vlado Handziski from Bookmarklet

"In my view there appears to be two primary ways that REST are used today. One is via the aforementioned CRUD approach (where CRUD = Create, Read, Update, Delete) and HTTP's verbs (which in the same order as CRUD are POST, GET, PUT, DELETE) are used to manipulate a data resource on a Web server. This is the most basic, most common way REST is used by application designers (sometime even using these to replicate traditional RPC) and is the foundational request/response model in REST services. Unfortunately, it's also probably the least interesting or powerful way to apply the full REST architectural style." - Vlado Handziski from Bookmarklet

"This article describes an electronic display that is fabricated by patterning electrically conductive wires (heaters) with micron-scale dimensions on one side of a sheet of paper, and thermochromic ink on the opposite side. Passing electrical current through the wires heats the paper and changes the thermochromic ink from colored (black, green, or other colors) to transparent; this change in property reveals the paper underneath the ink—exposing any messages printed on the paper—and serves as the basis for a two-state shutter display." - Vlado Handziski from Bookmarklet

Nice laymen intro to the various ways to auto-locate sensor nodes. But the text is missing the most promising options like using radio interferometry or alternative radio technologies like UWB and chirping (802.15.4a) - Vlado Handziski from Bookmarklet

"The NI wireless sensor network (WSN) platform delivers battery-powered nodes that offer industrial certifications, reliable networking protocols, and optional outdoor enclosures for long-term, stand-alone deployments. You can take advantage of NI LabVIEW software integration with NI WSNs to select between Windows and LabVIEW Real-Time OSs and simplify the extraction of high-quality measurement data." - Vlado Handziski from Bookmarklet

Google now only needs to make a small step in the direction of Opera Unite and implement the server part of the Wave protocol there and things will get really interesting. - Vlado Handziski

" The TikZ device enables LaTeX-ready output from R graphics functions. This is done by producing code that can be understood by the TikZ graphics language. All text in a graphic output with the tikz() funciton will can be typeset by LaTeX and therefore will match whatever fonts are currently used in the document. This also means that LaTeX mathematics can be typeset directly into labels and annotations! Graphics produced this way can also be annotated with custom TikZ commands." - Vlado Handziski from Bookmarklet

"LumiNet is a network of low-cost intelligent pixels that are connected in an organic fashion: Without a central point of control, each node only knows about its immediate neighbors, allowing for highly parallel, fault-tolerant networks in which information spreads from node to node." - Vlado Handziski from Bookmarklet

" Sensor.Network is a global exchange for sensor information. It allows researchers and scientists to share data with authorized partners. Authorized users can manage sensor installations, visualize collected data and share it with trusted partners. This service is not yet open to the general public. We are currently looking for beta testers. Please contact us if you'd like an invitation to participate. " - Vlado Handziski from Bookmarklet
