Scaled Composites Tier 1b

Tier 1b was the Scaled Composites internal company name of a mid-2000s program to develop a nine-passenger suborbital commercial human spaceflight platform.

The Tier 1b program was intended to be an evolutionary development of Scaled Composites Tier One program, which developed the Ansari X-Prize-winning entry in the 2004 spaceflight demonstration contest held by the X-Prize Foundation.

The principle hardware envisioned to be developed under the Tier 1b program were the White Knight Two carrier aircraft and the SpaceShipTwo suborbital spaceplane.

Sehnsucht (Rammstein album)

Sehnsucht (German for "yearning", see Sehnsucht) is the second album by German industrial metal band Rammstein, released on 25 August 1997.

The album booklet folds out to reveal six different covers, one for each band member (each photo depicting the member with bizarre facial-wear made out of ordinary kitchen objects like spatulas, spoons, forks etc.). The cover most commonly seen features Till Lindemann with an egg-lifter worn as a muzzle and bent forks over his eyes worn as sunglasses. The cover art was created by Austrian artist Gottfried Helnwein, who also created the cover for the Scorpions' Blackout album, which is very similar to the Sehnsucht cover and even the forks in both covers are the same. Sehnsucht is the only album entirely in German to be certified platinum by the RIAA in the US.

Track listing

All songs written and composed by Rammstein, except "Sehnsucht" written by Rammstein and Orgasm Death Gimmick and "Tier", written by Rammstein and Jürgen Engler. 

Multitier architecture

In software engineering, multitier architecture (often referred to as n-tier architecture) is a client–server architecture in which presentation, application processing, and data management functions are physically separated. The most widespread use of multitier architecture is the three-tier architecture.

N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or adding a specific layer, instead of reworking the entire application. A three-tier architecture is typically composed of a presentation tier, a domain logic tier, and a data storage tier.

While the concepts of layer and tier are often used interchangeably, one fairly common point of view is that there is indeed a difference. This view holds that a layer is a logical structuring mechanism for the elements that make up the software solution, while a tier is a physical structuring mechanism for the system infrastructure.
