Hasty Pudding cipher

The Hasty Pudding Cipher (HPC) is a variable-block-size block cipher designed by Richard Schroeppel, which was an unsuccessful candidate in the competition for selecting the U.S. Advanced Encryption Standard (AES). It has a number of unusual properties for a block cipher: its input block size and key length are variable, and it includes an additional input parameter called the "spice" for use as a secondary, non-secret key. The Hasty Pudding cipher was the only AES candidate designed exclusively by U.S. cryptographers.

The Hasty Pudding cipher is in the public domain.

The cipher

The Hasty Pudding cipher consists of 5 different sub-ciphers:

The Hasty Pudding cipher algorithms all use 64-bit words internally. The cipher is designed to run on 64-bit machines, which can easily perform simple operations on 64-bit words.

Key expansion

The Hasty Pudding cipher can take a key of any number of bits for any one of the five subciphers. The cipher itself uses a key table of 16,384 bits (256 64-bit words). To derive the key table from the key, the key expansion function uses the following algorithm:

STX1A

Syntaxin-1A is a protein that in humans is encoded by the STX1A gene.

Function

Synaptic vesicles store neurotransmitters that are released during calcium-regulated exocytosis. The specificity of neurotransmitter release requires the localization of both synaptic vesicles and calcium channels to the presynaptic active zone. Syntaxins function in this vesicle fusion process.

Syntaxin-1A is a member of the syntaxin superfamily. Syntaxins are nervous system-specific proteins implicated in the docking of synaptic vesicles with the presynaptic plasma membrane. Syntaxins possess a single C-terminal transmembrane domain, a SNARE [Soluble NSF (N-ethylmaleimide-sensitive fusion protein)-Attachment protein REceptor] domain (known as H3), and an N-terminal regulatory domain (Habc). Syntaxins bind synaptotagmin in a calcium-dependent fashion and interact with voltage dependent calcium and potassium channels via the C-terminal H3 domain. Syntaxin-1A is a key protein in ion channel regulation and synaptic exocytosis.

Atari Portfolio

The Atari Portfolio is a IBM PC-compatible palmtop PC, and was released by Atari Corporation in June 1989, making it the world's first palmtop computer.

History

DIP Research Ltd. based in Guildford, Surrey, UK released a product in the UK called the DIP Pocket PC in 1989. Soon after its release, DIP licensed this product to Atari for sale as the Portfolio in the UK and US. DIP officially stood for "Distributed Information Processing", although secretly it actually stood for "David, Ian and Peter", the three founding members of the company, all ex-Psion. The original founder of the company (first called "Crushproof Software") was Ian Cullimore, and the other two David Frodsham and Peter Baldwin.Ian Cullimore was involved in designing the early Organiser products at Psion before the DIP Pocket PC project. The technologic successor of the Portfolio was the also DIP developed Sharp PC 3000/3100. Another similar, but bigger palmtop of this time was the Olivetti Quaderno. DIP Research was later acquired by Phoenix Technologies in 1994.

Run!

"Run!" is the fifteenth episode of the first season of the NBC science fiction drama series Heroes. Regular cast members Milo Ventimiglia (Peter Petrelli) and Santiago Cabrera (Isaac Mendez) do not appear in this episode.

Plot

Meredith calls and informs Nathan that their daughter Claire is still alive. Aware that the scandal could ruin his political future, Nathan gives Meredith $100,000 for her silence. Elsewhere, Mrs. Bennet's health deteriorates, causing the rift between Claire and Mr. Bennet, since she blames him for her mother's condition. He grounds her after learning she skipped school, prompting Claire to be more outraged. Claire later shows up at Meredith's trailer, hoping that her biological father could help Mrs. Bennet. Meredith tells Claire that he will only disappoint her, and Meredith herself is going back to Mexico. She takes a picture of Claire as remembrance, which she later shows to a visiting Nathan. Meredith offers to introduce them, but Nathan refuses - this crushes an eavesdropping Claire. Visibly upset, Nathan gets inside his limo and leaves. Claire hurls a stone at his rear window in anger.

Run (Amy Macdonald song)

"Run" is the fifth single to be released from Amy Macdonald's debut album, This Is the Life. The single was released in the UK on 3 March 2008 and peaked at #75 in the United Kingdom for 1 week. Macdonald stated on stage at T in the Park 2008 that the song was inspired by a gig by The Killers in her hometown of Glasgow.
