  • "So I like to write a lot of music. I have not really released anything for a few years as I have been very busy freelancing in London on various web projects; and my music website was last updated before I started learning JavaScript.

    I want to get back into writing music over the next year or two and started to think about how to make my site a little different. One of my ideas was to use a dial styled like an electronic keyboard to control my page through AJAX, so I set about creating the dial you see to your left.

    As you can probably see, the dial has lights as point-markers which flash to the Beast Per Minute so when people click on my tunes, I can update the BPM on the UI Dial to add some depth to the user experience."

  • "Please join us on March 24 for Ada Lovelace Day
    Ada Lovelace Day is an international day of blogging (videologging, podcasting, comic drawing etc.!) to draw attention to the achievements of women in technology and science.
    Women’s contributions often go unacknowledged, their innovations seldom mentioned, their faces rarely recognised. We want you to tell the world about these unsung heroines, whatever they do. It doesn’t matter how new or old your blog is, what gender you are, what language you blog in, or what you normally blog about – everyone is invited. Just sign the pledge below (click ‘pledge’ after you have completed the reCaptcha) and publish your blog post any time on Wednesday 24th March 2010."
  • "PictureIt is a web-based animation program that gives users the sensation of turning the pages of digitized rare materials that would be otherwise difficult, if not impossible, to view or obtain. Volume 1 of John James Audubon’s Birds of America was selected as the inaugural PictureIt book for a few reasons. Foremost, the eight volume set has special meaning as the first purchase for the Library by the Board of Regents of the University of Michigan. As well, the University of Pittsburgh had already digitized all volumes of the Birds of America set and was willing to share the images with the Library. And finally, the illustrated plates of this set were intricately completed, making them as much art work as scientific work. Volume 1 of Audubon’s Birds of America was also selected for the first PictureIt book because its complex images demonstrate the product’s embedded magnification tool which allows users to get up-close and view the details of each illustration."
  • "MapTiler is graphical application for online map publishing. Your map can create overlay of standard maps like Google Maps, Yahoo Maps, Microsoft VirtualEarth or OpenStreetMap and can be also visualized in 3D form by Google Earth. Only thing you have to do for publishing the map is to upload the automatically generated directory with tiles into your webserver."
  • "Spritely is a simple plugin with only two key methods, sprite() and pan() both of which simply animate the background-image css property of an element. The difference between the two is that a 'sprite' image contains two or more 'frames' of animation, whereas a 'pan' image contains a continuous image which pans left or right and then repeats. Typically, in either case, you would use a png file (with or without transparency) for this. You might wish to use a transparent gif for Internet Explorer 6, though it probably won't look as good. Your html elements must already be the correct size you want the sprite to appear, but the background image will typically be larger than the html element, and the spritely methods reposition the background image within the html element."

  • "Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.
    Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.
    Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
    For more examples take a look at charting plugin: gRaphaël"
  • "Bailing out the financial system, but not bailing out schools in financial trouble because of the crisis, is unconscionable…"
  • "One of the most important concepts to understand in the coming years will be the power of digital ecosystems. On the surface it looks pretty obvious what they are and what they can be used for. But as I will show you in this essay, so much potential is still untapped."
  • "Every project I’ve worked on in the last two years has heavily involved the use of web APIs. Libersy at the time (no idea about now) had an architecture that was extensively API based, even for communication between internal applications (an architecture I strongly argued against, bee tea dubs). Since then I’ve futzed with web APIs almost exclusively. From very narrow focused uses like University of Michigan’s Bluestream Service, to more broad but still fairly local APIs like the Ann Arbor District Library’s soon-to-be-updated API, all the way to APIs of major web applications like Twitter and Flickr.

    Constant exposure has turned me into a bit of a snob: I can’t stand working with a poorly designed API! If you’re about to design or release an API for the web and want to avoid the ire of your developers, I’ve summed up the best (and worst) of what I’ve seen into 8 rules:"

  • "The real problem with the DIKW pyramid is that it's a pyramid. The image that knowledge (much less wisdom) results from applying finer-grained filters at each level, paints the wrong picture. That view is natural to the Information Age which has been all about filtering noise, reducing the flow to what is clean, clear and manageable. Knowledge is more creative, messier, harder won, and far more discontinuous. "
  • "It is at the three or four times in a 24 hour period that forex traders are well advised to switch tack and reverse near-term directional thinking. The European and NYMEX close are the U.S. based things to get under our belts, because then, maybe, the equity markets can reveal where they really want to go. Traders looking for moves outside of 06:00 and 11:00 EDT, and maybe 14:30 EDT may just find themselves sitting and waiting, wondering why they just bought the high of the day that then reversed.
    As the global economy travels through the contraction phase of its business cycle the leaning is towards looking at S&P futures trade to confirm sentiment. The speculators are never too far away from the S&P in times of fear; either selling into the fear of loss, or buying into the fear of missing profits. That is the reason for so much near-term volatility, and that is how things will stay until signs of GDP expansion are seen globally."
  • "I am confident that the Scrum Alliance sees the need for developer improvement, and that they are working toward making their members aware of the need. I am confident that they are working to provide resources that Scrum teams can use to begin to build the skills that they need. And I’m dedicated to influencing them in the right direction, and to bringing as many people into the situation to help accomplish that.

    In the end, what I care about is software development, as narrow and geeky as that might be. I care about other people finding the joy in the craft that I’ve found, and that means they have to discover the joy of life-long learning. I think this Scrum Alliance effort can help with that, and I think that “certification” has little or nothing to do with it. What counts will be what we tell the people who show up."

  • "Rightsizing will not “shunt” development to the exurban fringe. That’s what’s happening already. Most of the neighborhoods we’re discussing haven’t seen significant investment since the 1950s. If nothing is done, they will continue to deteriorate and the exurban fringe will continue to grow. If they can once again be made dense and sustainable, in part through consolidation, Detroit might have a fighting chance to compete against suburban neighborhoods by providing a safe, viable urban alternative."
  • "Another problem I've often had (as recently as last semester!) is that my goals for students–what they're expected to be able to do when the semester is over–are often not well defined. When we don't have a sense of where we're going, our 15-week courses often fall apart somewhere around week 7 or so. But this should not be such an issue in high school."

  • "BiotSavart is an application for Mac OS X and Windows XP that calculates the magnetic field resulting from general 3-D configurations of current-carrying conductors. It has proven useful in the design of superconducting and copper coil systems in physics laboratories worldwide. With BiotSavart, you design the conductors while you view them on the screen."
  • "Merlin Mann calls for websites to offer free, full-text RSS feeds. Jason Snell agrees, but wonders if offering them harms web traffic. As Boing Boing's had a full-content feed since the dawn of time, we can't really tell, but John Gruber switched only recently. He says that in his experience, a dip in traffic did result–but that in the long run, his RSS feed became the primary source of income for Daring Fireball:…"
  • "It is an experiment born from the common production of shared knowledges, and resistance to exploitation inside and outside the universities. Moreover it is a step toward the goal of building up autonomous institutions. The journal has two sections: "occupations" and "anomalies", which aim respectively to analyze transformations of the university and conflicts in knowledge production. The edu-factory journal has an editorial board, comprising critical scholars, students, and activists from all around the world, and it is open to free contributions. Finally, by experimenting with forms of collective reading and review, it aims to question the traditional peer review processes, and to open new spaces of thinking, learning and struggle within and against the hierarchies of the global knowledge and university market."
  • "While there seems to be endless conversation about the violence of smashing windows and the damage to the movement done by spontaneous action, there is a notable absence of discussion about the violence of class division in American society and its relationship with higher education.

    Is the movement so fragile that a smashed window destroys it–yet broken bodies don’t bring it to boiling point? We are told that the streets must be policed in order to be safe–that no one will join us–that people who would have supported the cause are now frightened to participate. Yet what we see is laughter, dancing and a freedom that is not possible to describe in the language of everyday capitalism. How, we must ask, is a movement that collapses under the weight of overturned trash cans going to withstand the presence of millions of people challenging their relationship to the economy?"

  • "They have an interesting opening conversation kicked off by Craig confessing (at 1:07) that, in the early days, he thought Stephen had it all together when, in fact, though Fry may have been quite successful, but he was a wreck. And so on and so forth. In the second segment there’s a throwaway reference to Russell and Whitehead’s Principia Mathematica in a conversation about Twitter. Jeeze! Sounds like these are educated people.

    Principia Mathematica!?#! Late night TV in America. Can it be long before hell freezes over?"

  • "Principle #6: Working for other people (full-time or in some other capacity) often divorces our experience of work from the fruit of our work. Living off your own projects, created of your own accord, is an entirely different kind of existence. And it is AWESOME."
  • "I am sorry but I do not participate in this dead ritual of anonymous ‘peer review’. This dishonest procedure brings out the worst in people. By now we all know that it does not improve quality but merely (re)produces mediocre standards and language. IMHO this format is out of sync with the open access aspects of today’s publishing tools and the debate-focused tools such as blogs, lists and forums, in particular when an article like this aims to contribute to the emerging research on online video. Criticism in the Internet context is a lively entity, not to be dealt with in such a grumpy backroom manner."
  • "We are often told that the Tea Party Movement represents some sort of disenfranchised “radical middle” in America that rejects both major parties’ inability to get together and solve problems. As the “Contract From America” shows, that’s totally wrong. At least when it comes to policy proposals, these folks are the hard-right wing of the Republican Party, upset that Barry Goldwater’s agenda from 1964 has never been implemented."
  • "NArray is an Numerical N-dimensional Array class. Supported element types are 1/2/4-byte Integer, single/double-precision Real/Complex, and Ruby Object. This extension library incorporates fast calculation and easy manipulation of large numerical arrays into the Ruby language. NArray has features similar to NumPy, but NArray has vector and matrix subclasses."
  • "AI4R is a collection of ruby algorithms implementations, covering several Artificial intelligence fields, and simple practical examples using them. A Ruby playground for AI researchers. It implements:…"

  • "To investigate the optimal shape a 3-D panel might take in order to harvest the most light, scientists used a "genetic algorithm" to evolve solar panels in a computer simulation.

    The model they developed randomly generated jumbles of flat, triangular double-sided solar panels and analyzed which generated the most power as a virtual sun moved across the sky. The best ones were then "mated" together for "offspring" that combined features of each with "mutations" that varied their structures. This process was then repeated for up to millions of generations, all in order to see what might evolve."
