CHAPTER 5 Hostages to Disappointment

James D. Showkeir Berrett-Koehler Publishers ePub

We were on a courtesy bus provided by a large hotel chain, heading to the airport. Without provocation, the bus driver began haranguing his captive audience about how terrible it was to work for the hotel. The management was unjust, he said, the employees were exploited, the practices and policies were stupid and unfair. On the fifteen-minute ride to the airport, everyone was held hostage as his critical rant persisted. Upon arrival at the airport, we were all experts about the failures of this hotel in its treatment of employees and customers. Relieved to get off, we boarded our flight hoping the same kind of monologue wasn’t on the pilot’s agenda.

After that incident, we asked ourselves, “How is it that a large organization like that hotel chain has employees who will represent it to customers in such negative and deprecating terms? How does a business survive this?”

Employee cynicism is not restricted to the hotel business. Listen to the conversations you have at work. Listen to the conversations employees have among themselves at any place of business. When you’re at the grocery store, the mall, restaurants, the airport, or the bank, pay attention to how people are conversing about their jobs. We’ve even heard call-center service representatives trashing their employers as their customers listen helplessly on the other end of the line. Disappointed employees spewing their cynicism about the workplace—within earshot of their customers! When that kind of cynicism is so pervasive, what does it say about organizational culture and the conversations that sustain it?

9. Acquiring Data

Ben Fry O'Reilly Media ePub

The first step in visualizing data is to load it into your application. Typical data sources might be a file on a disk, a stream from a network, or a digitized signal (e.g., audio or sensor readings). Unless you own the data and it's recorded in a definable, digitizable format, things can get messy quickly. How do you process weeks of surveillance video? How does one quantitatively acquire data from an hour-long meeting that involved a verbal discussion, drawings on a whiteboard, and note taking done by individual participants?

Thus, the acquisition stage covers several tasks that sometimes get complicated:

Unless you are generating your own data, you have to find a good source for the data you want.

If you don't own the data, you have to make sure you have the right to use it.

You may have to go through contortions to extract the data from a web page or other source that wasn't set up to make it easy for your application.

You have to download the data, which may present difficulties if the volume is large, especially if it's fast-changing.

Using what you know from adding the picker and the button, match the magnet with the method or file that you’ll need to edit to add the text field.

Wait a minute. We keep adding code to this .h file, but I still don’t know what a .h file really does!

What gives?

InstatwitViewController.h

A .h file is a header file.

It’s where you declare the interface and methods for a class. All of the classes we’ve used so far, like UITextField, NSString, and

NSArray, have header files you can look through. Take a minute to look through a couple and start thinking about what is happening in those files.

• ZipIt Wireless Messenger

Difficulty

• PC running Windows, Linux, or

BSD

moderate

In this project, we have a little fun with the ZipIt Wireless Messenger from

Aeronix. This $99 handheld device is sold as a way for kids to send instant messages without tying up the family PC. The ZipIt runs Linux and a custom instant messenger application. We’ll show you how to load another

Linux distribution so you can run the standard Unix utilities, including

SSH. We’ll also show you how to cross-compile and load your own programs onto the ZipIt.

As we went to press, the manufacturers of the ZipIT released a software upgrade

(version 2.xx) that makes it impossible to use the software update procedure described in this chapter. If you buy a ZipIt and it happens to have the old software

(version 1.xx), you have only one chance to load Linux as described here. Once the

ZipIt’s software is updated to version 2.xx, the only way to load Linux is by attempting the “3 wire mod” described at http://aibohack.com/zipit/serial.htm.
