One way to make the region more bicycle-friendly is for municipalities to make sure they connect existing trails and trail segments. Over the past decade or so there has been progress, DeSarra says.The Erie Canal trail and the Genesee Valley Greenway are examples; they even connect to each other. But there's still work to be done on those trails, such as making more connections or offering better markings.
The Greenway, combined with the Genesee Riverway, provides a straight shot from RIT to downtown, says Jon Schull, an RIT professor who's involved in bicycling-related projects at the school. The Greenway and Riverway are actually the most direct way to get from RIT to downtown. And the University or Rochester is along the way.
Students could live downtown "without having to worry about cars and parking and all of that," Schull says. "So I see that as a real transportation innovation that could make a difference."
The Greenway and the Erie Canal trail are not complete or connected in certain parts, mostly in lesser-populated areas. If they were, those paths could be useful to commuters, Dollard says. They could act as a bicycle highway from outlying areas into the city.
On a broader scale, there's the potential to connect trails from Lake Ontario and the City of Rochester to Williamsport, Pennsylvania, via 230 miles of trails, including the Genesee Riverway Trail and the Genesee Valley Greenway. The only hurdle is a few short gaps and one 20-mile gap that need to be connected, Schull says.
And that doesn't even touch on the cycling opportunities that are available in the Finger Lakes region, east of the Greenway. Bike-based scenic tours and wine country tours are already popular.

Stich Panorama is a plug-in for the GNU Image Manipulation Program (GIMP) which takes digital images and overlays one atop the other to make a panorama. With multiple applications of Stitch Panorama, any number of images can be combined into a large panorama. Features include image blending, color balance, and distortion matching. The above image was stitched together from four separate images. Try it yourself, the images are in the example directory.
The Stich Panorama plug-in gives give you a lot of control over how the final panorama is stitched together. You select the features to correlate in the images, how the blending is to be done, and how the colors are to be matched. Extensive control over the final panorama was a major design goal. There are other, more automated, tools available (see below), but I prefer to have as much control as possible over the stitching process. The final panorama uses a rectilinear projection, well suited to panoramas that do not cover an excessive field-of-view. However, the rectilinear projection will not work well for panoramas that cover a full 360 degrees.
Stich Panorama is written in the Python language and requires that your GIMP has python support compiled in.

Jon and Ricardo-
What a lovely afternoon for a ride on the Greenway!
If the purpose of this whole event is to raise awareness of the trail,
you've caused at least one new person to ride it. I'd ridden many times before from Genesee Valley Park to downtown, but had never ridden out to RIT before on the Lehigh Valley Trail. It makes RIT seem a whole lot closer to downtown then I'd ever thought before. It's a nice ride even with road tires!
There are a dozen flyers in page protectors along the trail now. They are mostly attached to Genesee River Trail signs and the gates at road intersections on the Lehigh Valley Trail. Some pictures are attached.
Please let me know if there's anything else that I can help you with in getting ready for Saturday. I plan to drive out to RIT on Saturday morning and ride the round trip, set up a table for R Community Bikes, and hang out at the event until it's over.
See you then!
Brad

There’s something about an iPhone music app. For musicians, it’s like having an instrument in your pocket. For nonmusicians, it’s a way to coax sounds -- often programmed to stay on key no matter what note one actually plays -- out of what may be the only instrumentlike device they ever pick up.
A main goal for many of these apps’ developers is to introduce nonmusical people to music, and musical people to different kinds of music. And when taken less as a serious instrument and more as a sampler for the wide world of music, these devices are wildly successful.
...
Many musical apps offer the ability to record a track, then add layers on top of it. Doing this between disparate apps is impossible without external recording software, but a multi-instrumental app like Moocow’s Band gives novices the opportunity to record and edit tracks with drums, bass and guitar, and make sure it all sounds pretty good (even if one doesn’t know how to play a lick of music). It’s as much a game as Guitar Hero, only instead of trying to keep up with prerecorded music, the goal is to make music of one’s own.

 | Description of cover figure: Illustration of self-organized pattern formation in migration games. The snapshot, taken after 200 time steps, shows the outcome of the spatial interaction of mobile individuals, who strategically interact with their four nearest neighbors and copy the strategy of their most successful neighbor. The simulation assumes that individuals earn no payoff, if they meet individuals who use the same strategy, while their outcome is positive, if interacting with individuals using another strategy. Strategy 1 is represented by blue disks, strategy 2 by red disks. A change to strategy 2 in the last time step is indicated in green, a change to strategy 2 by yellow. White spaces are empty. Individuals perform success-driven migration, i.e. they move to empty locations with a higher expected payoff. The maximum migration distance in one time step was assumed to be 5. Starting with uniformly distributed strategies, one observes an agglomeration of individuals, and individuals with different strategies mix. This is to be distinguished from the migratory dynamics in other spatial games, which lead to segregation patterns, for example, as studied by Nobel prize winner Thomas Schelling.

INTRODUCTION
I was quite excited a few months ago when I stumbled across the Vuzix VR920, a lightweight set of virtual reality eye glasses with dual hi-res displays. The amount of features packed into the three ounce package is really impressive:
Most importantly for us, it supports Second Life, as well as World of Warcraft, and a suite of games. The Second Life support is currently not native, but works well with mouselook mode, as I demonstrate in the video below. Vuzix was kind enough to loan me one to test out with Second Life and is actively seeking enterprising developers who may be interested in helping develop native Second Life support for the device. The VR920 is the first device that supports immersive three dimensional graphics, head tracking, as well as microphone and audio all in one device.

NEW YORK CITY: BIKING UP, CRASHES DOWN
-> According to the June 4th Transportation Alternatives' StreetBeat, "New data now reveals that there are 185,000 daily cyclists in New York City, an increase of more than one third from just four years ago. This staggering surge is not only a testament to the infrastructure improvements that have been implemented in the last couple of years, but also a contributing factor to the increased safety of cyclists throughout the city.
"It's a well established fact that for bikers there is safety in numbers. With more cyclists out and about, more drivers are accustomed to sharing the road. In fact, cycling in New York City is safer now than it has been at any time in recent memory, so spread the word and hit the streets..."

Despite a multitrillion dollar backlog of roadway and bridge repairs throughout the
country, almost a third of the money — more than $6.6 billion — was committed to new
capacity roads and bridges rather than to repair and other preservation projects.
The nation is growing, and many areas need substantial improvements in connectivity. Many
places will need additional roadway capacity. However, given the enormous roadway and
bridge repair backlog, its costs in terms of vehicle repairs, its threat to human safety, and the
job‐creation advantages of roadway preservation projects, this magnitude of new
construction cannot said to be fulfilling the goals of the ARRA.
2. States generally failed to take advantage of a golden opportunity offered by the flexibility
in the STP to make progress on the huge public transportation backlog, and move
towards a more balanced transportation system.
Given the growing demand, the need for upgrading identified in the ASCE report, and the many
benefits of public transportation, the $189 million in STP funding allocated by the states so
far is grossly inadequate. Even when the dedicated, non‐STP funding for public transportation
is taken into consideration, commitments to transportation choice fall far short of the need.
The $600 million in STP funding commitments to non‐motorized transportation is better, but
also fails to meaningfully respond to the public’s need for more affordable and healthy
transportation options. This level of spending for bicycling and walking will have minimal
impact on the nation’s stock of bicycle and pedestrian routes, or on individual mobility.
3. We could get much more from our transportation spending, but the federal program
isn’t set up to ensure that we get the most from the money spent. With scarce resources,
large backlogs and increasing challenges, it’s an opportunity we can’t afford to waste.
The data make clear that with different funding choices, greater progress could have been
made combating climate change, increasing energy security, increasing mobility for elderly
and low income populations, and reducing the repair backlog. More jobs could have been
created, more quickly. However, the federal transportation program does not clearly
articulate what goals should be achieved with each tax dollar spent, nor how to compare
different spending options against those goals, nor how to ensure progress towards meeting
them. The result is wasted opportunity and money.
