http://en.wikipedia.org/wiki/Rectification_of_names
A superior man, in regard to what he does not know, shows a cautious reserve. If names be not correct, language is not in accordance with the truth of things. If language be not in accordance with the truth of things, affairs cannot be carried on to success. When affairs cannot be carried on to success, proprieties and music do not flourish. When proprieties and music do not flourish, punishments will not be properly awarded. When punishments are not properly awarded, the people do not know how to move hand or foot. Therefore a superior man considers it necessary that the names he uses may be spoken appropriately, and also that what he speaks may be carried out appropriately. What the superior man requires is just that in his words there may be nothing incorrect. — Confucius, Analects, Book XIII, Chapter 3, verses 4-7, translated by James Legge[3]
NASA Unveils New Galactic Atlas
The Wide-field Infrared Survey Explorer
The WISE Source Catalog contains the attributes for 563,921,584 point-like and resolved objects detected on the Atlas Intensity images. Catalog sources are required to have a measured SNR>5 in at least one band, and to meet other criteria to insure a high degree of reliability. Attributes included for each entry in the Source Catalog include:
J2000 positions and uncertainties reconstructed using the 2MASS Point Source Catalog as astrometric reference. Astrometric accuracy is approximately ~200 mas RMS on each axis with respect to the 2MASS reference frame for sources brighter than SNR=40. Photometry and uncertainties in the four WISE bands. Photometry is performed using point source profile-fitting and multi-aperture photometry. WISE 5σ photometric sensitivity is estimated to be 0.068, 0.098, 0.86 and 5.4 mJy (16.6, 15.6, 11.3, 8.0 Vega mag) at 3.4, 4.6, 12 and 22 μm in unconfused regions on the ecliptic plane. Sensitivity is better at higher ecliptic latitudes where coverage is deeper and the zodiacal background is lower, and poorer when limited by confusion in high source density or complex background regions. Saturation affects photometry for sources brighter than approximately 8.1, 6.7, 3.8 and -0.4 mag at 3.4, 4.6, 12 and 22 μm, respectively. Measurement quality flags, image artifact contamination flags, extended source and variability flags, and association information cross-referencing WISE sources with the 2MASS Point and Extended Source Catalogs.

Amazon S3 Performance Tips & Tricks
We frequently see new workloads introduced to S3 where content is organized by user ID, or game ID, or other similar semi-meaningless identifier. Often these identifiers are incrementally increasing numbers, or date-time constructs of various types. The unfortunate part of this naming choice where S3 scaling is concerned is two-fold: First, all new content will necessarily end up being owned by a single partition (remember the request rates from above...). Second, all the partitions holding slightly older (and generally less 'hot') content get cold much faster than other naming conventions, effectively wasting the available operations per second that each partition can support by making all the old ones cold over time.
[Snowflake, system to generate unique ID numbers for tweets[(http://engineering.twitter.com/2010/06/announcing-snowflake.html)
Our requirements for this system were pretty simple, yet demanding:
We needed something that could generate tens of thousands of ids per second in a highly available manner. This naturally led us to choose an uncoordinated approach.
These ids need to be roughly sortable, meaning that if tweets A and B are posted around the same time, they should have ids in close proximity to one another since this is how we and most Twitter clients sort tweets.[1]
Additionally, these numbers have to fit into 64 bits. We’ve been through the painful process of growing the number of bits used to store tweet ids before. It’s unsurprisingly hard to do when you have over 100,000 different codebases involved.
Flake: A Decentralized, K-Ordered Unique ID Generator in Erlang
At Boundary we have developed a system for unique id generation. This started with two basic goals:
- Id generation at a node should not require coordination with other nodes.
- Ids should be roughly time-ordered when sorted lexicographically. In other words they should be k-ordered 1, 2.

Aaron Straup Cope (Authority Records, Future Computers and Other) Unfinished Histories
"If you, as curators and archivists and generally anyone involved in the preservation of promotion of cultural heritage, think that the authority record is the pinnacle of your careers – that is, the most important thing you will leave behind – then you are about to be eaten by robots."
In Texas Tradition, Museums That Enshrine the Quirky
Texans ... prize their barbed wire (The Devil’s Rope Museum), but they also love their classic-rock eight-track tapes from the 1970s (the Eight Track Museum in Dallas), their bugs (the Cockroach Hall of Fame Museum in Plano), their cars (the Central Texas Museum of Automotive History in Smithville), their sports (the Texas Basketball Museum in Carmine) and their toilet seats (Barney Smith’s Toilet Seat Art Museum in San Antonio). The state has numerous established, well-financed museums that are members of the American Association of Museums in Washington — the Museum of Fine Arts in Houston, the Museum of Nature and Science in Dallas — but there are dozens of others that exist as museums because someone put up a sign saying so.

Harvard Journal of Law & Technology Volume 25, Number 1 Fall 2011 TRAGEDY OF THE DATA COMMONS Jane Yakowitz*
Information is personally identifiable if it can be traced to a specific individual.17 Obviously, information that is tied to a direct identifier, such as name, address, or social security number, is personally identifiable. For example:
Jane Yakowitz is actually a giant cockroach.
However, PII is not limited to information that directly identifies a subject. Included in its ambit are pieces of information that can be used in combination to indirectly link sensitive information to a par- ticular person.
A 31-year-old white female who works at Brooklyn Law School and lives in ZIP code 11215 is actually a giant cockroach.
Or:
All 31-year-old females that live in ZIP code 11215 are actually giant cockroaches.
I will use the term “indirect identifiers” to mean pieces of information that can lead to the identity of a person through cross-reference to other public sources or through general knowledge.18 “Non- identifiers,” in contrast, cannot be traced to individuals without having special non-public information.
