So, what’s chumby anyway?


chumby plays your selected=

chumby takes your favorite parts of the internet and delivers them to you in a friendly, always-on, always-fresh format. It’s a window into your internet life that lives outside your desktop, so content like weather, news, celebrity gossip, podcasts, music, and more has a place to play away from your world of documents and spreadsheets. Just plug in your chumby, connect to your network, and use your computer to create a lineup of favorites from over 1,500 apps in more than 30 categories, with new ones arriving all the time. Then let your chumby do its thing — streaming everything you like, from sports scores to stock quotes, from video clips to interactive games, from photos to trivia.

ScienceShot: Meet the World’s First ‘Dark Sky Island’ – ScienceNOW

ScienceShot: Meet the World’s First ‘Dark Sky Island’ – ScienceNOW

Sark is an astronomer’s paradise. The smallest of the four landmasses in the United Kingdom’s Channel Islands, it has no paved roads, no cars, and no public street lighting. Thus it sports precious little of the light pollution that bedevils those seeking a clear view of the night sky. Today, the Tucson-based International Dark-Sky Association (IDA), which works to boost awareness of light pollution and its effects, recognized these qualities by designating Sark the world’s first “dark sky island.” The island (inset) is home to about 650 residents, and many of Sark’s homeowners and businesses have modified their lighting to minimize the amount of light spilling upwards, says Steve Owens, a member of the IDA committee that identifies and recognizes sites with suitably dark skies. With the new recognition, he notes, Sark will likely see a boost in tourism, especially among amateur astronomers who might visit to take advantage of the island’s crisp, clear skies during winter months, perhaps to catch a spectacular view of the Milky Way (main picture).

Flickr Accidentally Wipes Out Account: Five Years And 4,000 Photos Down The Drain

Flickr Accidentally Wipes Out Account: Five Years And 4,000 Photos Down The Drain

Yahoo’s Flickr may have another PR nightmare on their hands. IT architect and Flickr user Mirco Wilhelm couldn’t log on to his 5-year old account yesterday, and when he asked the Flickr team about this issue they flat out told him they had accidentally flushed his entire account, and the 4,000 photos that were in it, straight down the drain.

Apparently Wilhelm reported a Flickr user with an account that held ‘obviously stolen material’ to the company last weekend, but a staff member erroneously incinerated his account instead of the culprit’s.


Unfortunately, I have mixed up the accounts and accidentally deleted yours. I am terribly sorry for this grave error and hope that this mistake can be reconciled. Here is what I can do from here:

I can restore your account, although we will not be able to retrieve your photos. I know that there is a lot of history on your account–again, please accept my apology for my negligence. Once I restore your account, I will add four years of free Pro to make up for my error.

Please let me know if there’s anything else I can do.

Again, I am deeply sorry for this mistake.

Autonomous Quadrotor Teams May Build Your Next House | BotJunkie

Autonomous Quadrotor Teams May Build Your Next House

Back in July, we wrote about how UPenn’s GRASP Lab had taught their quadrotors to work together to grasp and move things. The next step, it seems, is teaching the quadrotors to work together to grasp and move things and actually build buildings. The video above shows a team of quadrotors cooperating to construct the framework of a (rather small) building. The building’s structure is held together with magnets, and the quadrotors are able to verify that the alignment is correct by attempting to wiggle the structural components around, which is pretty cool.

The origin of the Droste effect

Droste effect – Wikipedia, the free encyclopedia

The effect is named after the image on the tins and boxes of Droste cocoa powder, one of the main Dutch brands, which displayed a nurse carrying a serving tray with a cup of hot chocolate and a box with the same image.[2] This image, introduced in 1904 and maintained for decades with slight variations, became a household notion. Reportedly, poet and columnist Nico Scheepmaker introduced wider usage of the term in the late 1970s.[3]

The Droste effect is not a recent idea. It was for instance used by Giotto di Bondone in 1320, in his Stefaneschi Triptych. The polyptych altarpiece portrays in its center panel Cardinal Giacomo Gaetani Stefaneschi offering the triptych itself to St. Peter[4]. There are also several examples from medieval times of books featuring images containing the book itself or window panels in churches depicting miniature copies of the window panel itself. See the collection of articles Medieval mise-en-abyme: the object depicted within itself[5] for examples and opinions on how this effect was used symbolically.

CDE: automatic packaging of Code, Data, and Environment

CDE is a tool that automatically packages up the Code, Data, and Environment involved in running any set of Linux commands so that they can execute identically on another computer without any installation or configuration. The only requirement is that the other computer have the same hardware architecture (e.g., x86) and major kernel version (e.g., 2.6.X) as yours.

CDE allows you to easily run programs without the dependency hell that inevitably occurs when attempting to install software or libraries.

You can use CDE to allow your colleagues to reproduce and build upon your computational experiments, to quickly deploy prototype software to a compute cluster, and to submit executable bug reports.
