The Built Environment

What is Joomla?

Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.

What is Wera?

WERA (WEb ARchive Access) is an archive viewer application that gives an Internet Archive Wayback Machine-like access to web archive collections as well as the possibility to do full text search and easy navigation between different versions of a web page.

The Charming Gadfly Who Saved the High Line - New York Times

Manhattan Up Close
The Charming Gadfly Who Saved the High Line
By JOHN FREEMAN GILL

FOR all the giddiness surrounding the transformation of the High Line, the city's favorite elevated railway, into a linear park running from the meatpacking district to Hell's Kitchen, nearly one-third of it remains in danger of being torn down. The stretch between 30th and 34th Streets, where the High Line loops gracefully around parts of the railyards between 10th and 12th Avenues, is shaping up as the last battleground for the innovative project.

...

For Mr. Obletz, the railyards west of Penn Station were not a hotly contested development opportunity, but literally his backyard. Beginning in the late 1970s, when the western fringe of Hell's Kitchen was such a forbidding wasteland after dark that cabbies would not take riders there, Mr. Obletz lived in the railyards in a formerly derelict concrete-block railroad building near 30th Street and 11th Avenue. Next door, on a spur of track, he kept two elegantly appointed antique rail cars he had obsessively restored.

A train buff's train buff, Mr. Obletz worked as a real estate consultant for the transit authority and gave elaborate dinner parties in his gleaming, 68-ton Pullman dining car. Places were set with New York Central Railroad china and flatware, with the host sometimes attired in a blue velvet smoking jacket and saddle shoes.

"He was an absolute charmer," said the playwright Paul Rudnick, who along with other creative types like the choreographer Tommy Tune was a guest. "It was such a treat to visit him because you felt you were leaving New York, and in a sense planet Earth. You'd entered Train Land."

Mr. Obletz's rail cars sat a stone's throw from a long, rusting overhead structure. One day he climbed a metal staircase and stepped with astonishment onto what he later learned was the defunct 1934 freight railway known as the High Line.

"It was a terra incognita up there," Mr. Obletz told a New York Times reporter for a 1984 article. "Unrestricted space. Unimaginable tranquillity."

Europe's Infrastructure Frenzy Seems to Be Catching On in U.S. - Preview

Europe's Infrastructure Frenzy Seems to Be Catching On in U.S.
It isn't surprising Pennsylvania wants to offload its shabby 66-year-old turnpike. What is shocking, though, is that nearly 50 firms, including a few of Wall Street's finest, should want to lease the highway. True, not all will end up bidding. But this is a sure sign that the infrastructure frenzy, which has been going strong in Europe over the past couple of years, has spread to America.

CommsDesign - Storage Area Network Overview

Good quick description of serverless backup. From the website:

Serverless backup over SANs requires three major components:

The backup application itself

The Extended SCSI Copy Command standard

A protocol-aware, intelligent SAN appliance that can recognize protocols from many heterogeneous systems and transmit data at high speeds to the tape and DLT libraries.

With serverless backup, the data flows across the SAN directly from the disk drive to the tape device, with no data moving through the server. The enterprise servers only need to host the backup application, and the backup application determines what needs to be backed up and sends the command to a "copy agent" embedded in an intelligent SAN appliance. The intelligent SAN appliance detects the source and destination parameters, retrieves the data from the storage devices, writes it to the tape or DLT libraries, and reports completion (or status) back to the backup application.

We'd need the Helix server, Helix proxy, and Helix DRM. This would let us design a full blown service. We should base it on Windows servers and connect to a large, fast disk array. For now, a single scale system would be fine with, say, 25 streams.
