Asian Room Service

Asian Room Service
Be warned, you’re going to find yourself talking “funny” for a while after reading this. It was nominated best email of 1997.
A telephonic exchange between a hotel guest and roomservice, at a hotel in Asia, which was recorded and published in the Far East Economic Review…..
Room Service: “Morny. Ruin sorbees”
Guest: “Sorry, I thought I dialled room-service”
RS: “Rye..Ruin sorbees..morny! Djewish to odor sunteen??”
Guest: “Uh..yes..I’d like some bacon and eggs”
RS: “Ow July den?”
G: “What??”
RS: “Ow July den?…pry,boy, pooch?”
G: “Oh, the eggs! How do I like them? Sorry, scrambled please.”
RS: “Ow July dee bayhcem…crease?”
G: “Crisp will be fine”
RS: “Hokay. An San tos?”
G: “What?”
RS: “San tos. July San tos?”
G: “I don’t think so”
RS: “No? Judo one toes??”
G: “I feel really bad about this, but I don’t know what ‘judo one toes’ means.”
RS: “Toes! toes!…why djew Don Juan toes? Ow bow singlish mopping we bother?”
G: “English muffin!! I’ve got it! You were saying ‘Toast.’ Fine. Yes, an English muffin will be fine.”
RS: “We bother?”
G: “No..just put the bother on the side.”
RS: “Wad?”
G: “I mean butter…just put it on the side.”
RS: “Copy?”
G: “Sorry?”
RS: “Copy…tea…mill?”
G: “Yes. Coffee please, and that’s all.”
RS: “One Minnie. Ass ruin torino fee, strangle ache, crease baychem, tossy singlish mopping we bother honey sigh, and copy….rye??”
G: “Whatever you say”
RS: “Tendjewberrymud”
G : “You’re welcome”


Prinzipiell: Übertragen von Erfahrung (eigener oder fremder).
1. Allgemein: Dauer einer Autoreise Köln-Hamburg
Einflußfaktoren: Entfernung, Geschindigkeit, Auto, Fahrer, Ferienzeit,….
2. Projektaufwand/-termin
2.1 Welche Phasen und Aktivitäten sind “drin”? Z.B. QS-Aufgaben, LA-Folien, Statusberichte? (Klären anhand Blueprint/Vorgehensmodell)
2.2 Schätzgenauigkeit vs. Schätzaufwand (100% gibt 0%)
2.3 Zeitpunkt der Aufwandsschätzung (selten kann man sich den aussuchen!)
2.4 Projekttypen: Neuentwicklung individueller Software, Modifikation von Software, Customizing von SSW,…
3. Methoden
3.1 COCOMO (Bary Boehm 1978) aus den Source Instructions berechnet er MM, TDEV und Teamgrösse. Genauigkeit plusminus 20%.
3.2 Functionpoint (Albrecht IBM) Functionpoints = Masszahl wie Entfernungskilometer. Im ersten Schritt werden Functionpoints aus Anzahl von Eingaben, Ausgaben und Referenzdaten ermittelt. Dazu kommen kleinere Korrekturfaktoren. Im zweiten Schritt werden aus Erfahrungswerten den Anzahl FPs der Aufwand in Mannmonaten zugeordnet.
3.3 Analogiemethoden: Auf der Basis eines bekannten ähnlichen Projektes wird das zu schätzende Projekt einer Anweichungsanalyse unterzogen. Erkannte Anweichungen versucht man durch Zuschläge oder Abschläge zu berücksichtigen. Gut, wenn umfangreiche Erfahrungen mit ähnlichen Projekten. Schlecht, wenn wesentliche Unterschiede zwischen den Projekten bestehen.
3.4 Prozentsatzmethoden: Bei vorhandenem Phasenmodell mit Aufwandsverteilung kann aus einer Ist-Zahl auf alle Rest-Zahlen geschlossen werden. Problematik der Extrapolation. Phasenmodell muss identsch sein.
3.5 Kombinationen aller Methoden von 1-4 und weiterer sind in der Praxis notwendig.

Background on the Fax Industry

Background on the Fax Industry
The facsimile was invented in 1843 by Alexander Bain, earlier than the telephone invented by Bell in 1876. The facsimile came into practical use much more slowly than did the telephone. Using early achievements in electronic engineering such as the vacuum tube and photo cell, practical models were developed in the 1920’s in the United States, Germany, France, and Japan. After their introductions, facsimile apparatuses were used in specialized areas, such as for transmission of news pictures and weather maps, and pickup and delivery of telegrams.
Facsimiles are classified into either photographic facsimile, in which the original copy is reproduced faithfully with graded tonal densities, or document facsimile, in which the original copy is reproduced primarily with black and white.For many years before the growth of the fax machines, Alexander Bain modified a system of synchronized electric clocks to make the first fax machine. He devised a way of skimming raised metallic letters with a stylus attached to a pendulum. With this method, a stream of electric pulses were sent by a wire to the receiving device where a second synchronized pendulum swept across chemically-treated paper, leaving a dark mark wherever a pulse occurred. The rate at which the apparatus was capable of working was discovered accidentally by a broken spring. The fax principle was established and Bain received 7,000 for his telegraphic patent. The money he received was wasted in litigation and he died a poor man.

After the death of Bain, a handful of European inventors began to build upon his non-success and refine the fax principle. Giovanni Caselli, Frederick Bakewell, Ludovic d’Arlincourt and Edouard Belin each contributed innovations, but it was not until 1902 that Arthur Korn, a German, demonstrated the first photo-electric scanning fax system. The previous methods had depended upon Bain’s contact-scanning technique. In 1902, Dr. Arthur Korn developed a photoelectric scanning system for the transmission and reproduction of photography, and in 1907, he established a commercial picture transmission system. This system eventually linked Berlin, London and Paris and became the world’s first facsimile network. Facsimile then made slow but steady progress through the ‘20s and ‘30s, and in 1934 the Associated Press introduced a wire photo service. Korn’s breakthrough of giving the fax machine “sight” prompted serious commercial experimentation by three American telecommunications giants: AT&T, RCA and Western Union. Korn’s success and achievement in using the fax brought new development and direction for broadcast publishing to the United States.

Alice in Wonderland
Alice came to a fork in the road. ‘Which road do I take?’ she asked. ‘Where do you want to go?’, responded the Cheshire cat. ‘I don’t know.’ Alice answered. ‘Then,’ said the cat, ‘it doesn’t matter.
