http://josephmcohen.com/post/71536977591/toyota-manufacturing-principles Toyota Manufacturing Principles HEART 2 NOTES Throughout its history, Toyota has made a habit of labeling its business concepts and guiding values. In learning more about the company, I’ve picked up a few useful concepts from their manufacturing vocabulary: Jidoka:   Automation with a Human Touch The idea of  jidoka  is that humans should work with machines to produce the best possible outcome, leveraging the execution ability of a machine and the judgement of a human. I learned this term on a tour of Toyota’s Nagoya factory, where  jidoka  is a guiding principle. The concept originally comes from Sakichi Toyoda’s invention of the automatic loop in 1896, back when Toyota was in the textile business. Jidoka will become increasingly relevant as computers continue to do more and more work that humans have historically done. The concept has been ported to English under the name ...

Strategy 1:Use server to provide configuration: Every client will have to use this configuration. No per client configuration option. Requires setting jvm params Strategy 2: Send configuration file to client on default location. Per client configuration possible Strategy requires transmitting file to client. Requires setting jvm params Strategy 3: Build client handler looking for flags. Per client configuration possible Strategy requires building handler. Not easy to add features later on. Doesn't require jvm params Key design rights: Passing bits to individual client is key rather server side Use the build-in logback handler is better rather building one. Rationally: passing logger:level is the possible, handler will look if logger are set and will use if found. handler will reset all previous configuration. Best solution: Key is pass the file. This will be future proof Works per client Requires setting jvm params

What is logback? Logback is intended as a successor to the popular log4j project. It was designed by Ceki Gülcü, log4j's founder.  package chapters . introduction ; import org . slf4j . Logger ; import org . slf4j . LoggerFactory ; public class HelloWorld1 {   public static void main ( String [] args ) {     Logger logger = LoggerFactory . getLogger ( "chapters.introduction.HelloWorld1" );     logger . debug ( "Hello world." );   } } Logger, Appenders and Layouts Logback is built upon three main classes:  Logger ,  Appender  and  Layout . These three types of components work together to enable developers to log messages according to message type and level, and to control at runtime how these messages are formatted and where they are reported. The  Logger  class is part of the logback-classic module. On the other hand, the  Appender  and  Layout  interfaces are p...

What is Carpet Area, Built up Area, Saleable Area? Please read this 4 page article few times to understand how builders use the above terms to fool people in thinking about apartment sizes. Technically on paper you can buy 1500 sft apartment with real area far less then that. http://www.ramindiagroup.com/ CustomerWelfare-AreaConcepts. html Summary: Typical Calculation:  Super Build-up Area = ( Carpet Area + (balcony/terrace) * 0.5 ) *  1.3 Carpet Area - Area within your apartment walls. Balcony - Area with ceiling but without walls on all sides. Terrace - Area without ceiling and without walls on all sides Why are we multiplying total area by 1.3 ?  Thats called loading factor, builders give exclusive rights to area within your aprt walls but not to stairs, and lifts, and to cover this cost they add 30% more. P.S: Parking space cost in Hyderabad is around 1-15 Lakhs.

Its a very common practice in India specially southern city Hyderabad to have maids helping housewives and elderly people with daily chores. As per the Muqaddimah well known book on economics in IvyLeague circle the author argues that maids/servent profession is not natural to human beings and its hard to find someone with basic qualities being honest and hardworking. However the major implication of living with maids and servent's is people tend to acquire investigative attitude because of always being in an environment of being mistrust and verification. This leads to several complications and fallouts in one's personal life coz people behave with family and friends in the same attitude.

STORY II.  The Oilman and his Parrot.  An oilman possessed a parrot which used to amuse him with its agreeable prattle, and to watch his shop when he went out. One day, when the parrot was alone in the shop, a cat upset one of the oil-jars. When the oilman returned home he thought that the parrot had done this mischief, and in his anger he smote the parrot such a blow on the head as made all its feathers drop off, and so stunned it that it lost the power of speech for several days. But one day the parrot saw a bald-headed man passing the shop, and recovering its speech, it cried out, "Pray, whose oil-jar did you upset?" The passers-by smiled at the parrot's mistake in confounding baldness caused by age with the loss of its own feathers due to a blow. Rumi, Maulana Jalalu-'d-din Muhammad (2011-05-16).
