“Kryptos,” the sculpture nestled in a courtyard of the agency’s Virginia headquarters since 1990, is a work of art with a secret code embedded in the letters that are punched into its four panels of curving copper.

“Our work is about discovery — discovering secrets,” said Toni Hiley, director of the C.I.A. Museum. “And this sculpture is full of them, and it still hasn’t given up the last of its secrets.”
Kryptos is a sculpture located on the grounds of CIA Headquarters in Langley, Virginia. Installed in 1990, its thousands of characters contain encrypted messages, of which three have been solved (so far). There is still a fourth section at the bottom consisting of 97 or 98 characters which remains uncracked. This webpage contains some information about the sculpture, including some photos collected from around the web, some rubbings of the sculpture taken by your intrepid webmistress, links to other articles and Kryptos discussion groups here and there, and information about other encrypted sculptures which have been created by the sculptor, Jim Sanborn.

The movement may have engaged advocates, developers, academics, companies, but it's not met its grandiose vision of empowering the public. USAspending.gov, after three redesigns, is "pretty impressive looking, but its data is almost completely useless," Ellen Miller, Sunlight Foundation's co-founder said at Gov 2.0 Summit. If open government continues to take place within a blackbox, Wikileaks will have to increasingly take on the mantle of disclosure and transparency.
The Bureau of State Audits has released a report that says the state doesn't fully comply with the Dymally-Alatorre Bilingual Services Act. The 1973 law mandates that government agencies serving a "substantial" number of non-English-speaking people must employ enough bilingual workers to "ensure provision of information and services to the public in the language of the non-English-speaking person."
The State Personnel Board needs to do more to enforce the law at the state level, auditors said, and the departments/agencies reviewed needed to do a better job of surveying their foreign language needs and follow through, such as providing translations of written materials.
Although Windows 3.0 and its successors 3.1 and 3.11 became the dominant PC operating system, it was not particularly robust or reliable, networking was awkwardly bolted-on, and security non-existent. Microsoft knew it had to rebuild Windows from scratch, and had been working on the project since 1988 when Dave Cutler was hired from Digital Equipment Corp. for that purpose.
Flaws in the DOS/Windows family might be forgiven on the grounds that its evolution was partly accidental. Nobody realised when Microsoft acquired QDOS (Quick and Dirty Operating System) in 1980 that it would end up as the foundation of PC computing. Windows NT on the other hand was Microsoft's opportunity to get it right.
