Programming Productivity
Прачытаў кніжачку Capers Jones - Programming Productivity. Выйшла ў 1986 годзе, ў прыкладах аўтар параўноўвае праграмістых на Асэмблере, PL/1 і COBOLе.
Пры гэтым шмат якія праблемы - адсутнасьць стандартных мэтрык, няўлік падчас ключавых фактараў і г.д. - засталіся й зараз і даюць тэмы для артыкулаў, напрыклад, Спольскага. Уразіла адно назіраньне:
A 50-hour workweek is 25% more than a normal 40-hour week. If a new tool or technology is installed that improves productivity by 25% in real life, which is not a trivial amount, it may result in nothing more than the personnel going home on time and not working Saturdays. While this is valuable in human terms, project management will see no perceptible cost or schedule reductions from the technology, since what was eliminated was unpaid overtime.
As surprising as it may seem when first considered, a tool or technology may have to yield more than a 30% increase in real productivity before its influence can even be measured, since a 20% or 25% gain may be absorbed merely by reduction of unpaid overtime

Проста Аліса за люстэркам нейкая!

Адкапаў шыкоўны дыск - 9 альбомаў Dead Can Dance у MP3. Вось так, людзі дэкаду працуюць, ствараюць Музыку зь вялікае М, запісваюць - а прадукт іхнае дзейнасьці можна набыць за якія тры баксы, таньней, чым папоўднічаць.

Long term project planning
New College, Oxford, is of rather late foundations, hence the name. It was founded around the late 14th century. It has, like other colleges, a great dining hall with big oak beams across the top, yes? These might be two feet square, forty-five feet long.

A century ago, so I am told, some busy entomologist, went up into the root of the dining hall with a penknife and poked at the beams and found that they were full of beetles. This was reported to the College Council, who met in some dismay, because where would they get beams of that calibre nowadays?

One of the Junior Fellows stuck his neck out and suggested that there might be on College lands some oak. These colleges are endowed with pieces of land scattered across the country. So they called in the College Forester, who of course had not been near the college itself for some years, and asked him about oaks.

And he pulled his forelock and said, “Well sirs, we was wonderin’ when you’d be askin’.”

Upon further enquiry it was discovered that when the College was founded, a grove of oaks had been planted to replace the beams in the dinning hall when they became beetly, because oak beams always become beetly in the end. This plan had been passed down from one Forester to the next for five hundred years. “Your don’t cut them oaks. Them’s for the College Hall.”

па кроплі давіць зь сябе індуса
Трэба зрабіць праграмку, якая робіць амаль тое-ж, што й старая, але мяняе другі парамэтр і па другіх законах. У старой кут мяняўся ад 0 да 180, адпаведна, была канстанта
   HALF_CIRCLE = 180;
У новай кут трэба мяняць да 360. Падумаў, што калі ўвадзіць новую канстанту, дык гэта-ж трэба яе апісваць і мяняць назву канстанты ў кодзе. Зь цяжкасьцю падавіў жаданьне перарабіць на
   HALF_CIRCLE = 360;
каб не мяняць код
