Why Google May Fail

 

Staffing: Exacerbating the Problem

 

In talking to the OEMs, one of their biggest complaints was that the people they interface with are rude, unprofessional, inexperienced, clueless and generally unable to successfully resolve issues in a timely manner. The level of frustration with some of the OEMs is incredibly high.When confronted with this problem, Google’s common response has been that they simply can’t find qualified people, which is kind of amazing given the level of unemployment that exists in the world.This suggests that Google’s hiring policy is at fault; the company is known to favor recent graduates who will start at low salaries but have high GPAs, instead of more experienced employees. This exacerbates the quality problems significantly because it means these problems aren’t being properly communicated, escalated or resolved. In fact, in talking to the OEMs, you get a sense that much of the team that Google has working on operating systems are actually learning on the job. It kind of makes it even more amazing that they got a product out that works as well as it does.

QJson – Home

QJson

the easiest way to manage JSON objects with Qt

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It can represents integer, real number, string, an ordered sequence of value, and a collection of name/value pairs.

QJson is a qt-based library that maps JSON data to QVariant objects: JSON arrays will be mapped to QVariantList instances, while JSON objects will be mapped to QVariantMap.

Easy to use

QJson is fast and reliable. Don’t waste your time writing another JSON parser!

Converting a JSON object to a QVariant requires just three lines of code:

1 // create a JSonDriver instance
2 QJson::Parser parser;
3 bool ok;
4 
5 // json is a QString containing the data to convert
6 QVariant result = parser.parse (json, &ok);

It’s also possible to convert QVariant instances to JSON objects:

1 // create a Serializer instance
2 QJson::Serializer serializer;
3 const QByteArray serialized = serializer.serialize( json_object );

It’s possible to serialize QObject instances into JSON and also to initialize a QObject using the values stored inside of a JSON object.
