We ve all had projects in which we spent 80 percent of the time working on a small piece we found interesting and 20 percent of the time building the other 80 percent of the program Your employer can t force you to be a good programmer; a lot of times your employer isn t even in a position to judge whether you re good If you want to be great, you re responsible for making yourself great It s a matter of your personal character Once you decide to make yourself a superior programmer, the potential for improvement is huge Study after study has found differences on the order of 10 to 1 in the time required to create a program.

They have also found differences on the order of 10 to 1 in the time required to debug a program and 10 to 1 in the resulting size, speed, error rate, and number of errors detected (Sackman, Erikson, and Grant 1968; Curtis 1981; Mills 1983; DeMarco and Lister 1985; Curtis et al 1986; Card 1987; Valett and McGarry 1989)..

The implications of this one service are quite complex. In this case, you can see that this service relies on the Telephony service, which in turn relies on both the Plug And Play service and the Remote Procedure Call (RPC) service running. Conversely, if the Remote Access Connection Manager service is not running, neither the Internet Con nection Firewall (ICF)/Internet Connection Sharing (ICS) service nor the Remote Access Auto Connection Manager service will start.

You can t do anything about your intelligence, so the classical wisdom goes, but you can do something about your character. It turns out that character is the more decisive factor in the makeup of a superior programmer.

Most of the services that are installed by Windows Server 2003 run under the Local Sys tem context; that is, the special Local System account controls when the service should be started and stopped. However, additionally loaded services (usually by Microsoft or third-party applications) run under potentially different contexts. Often, when the ser vice is being loaded, the administrator is asked for specific credentials under which the service is run. This way, instead of providing the service unobstructed access to the system by means of the special System account, the service is restricted to the context of the user the administrator provides. Sometimes this account is a local user to the computer (say, a local administrator account); other times, the account has even fewer privileges. The level of access required depends on the requirements of the application and the services it installs. The best approach, however, is to provide to the account only the least amount of access that is required. For instance, if the service account could start with a local user account, you should not necessarily make the account a local administrator account simply because it is going to be used to control a service. Consult your installation doc umentation for specific rights required for each application you are planning to load.

request an IP address from each other during the connection establishment process. But if one of the routers does not have an address to assign, both routers continue with the connection establishment process. The logical interface on the point-to-point connection does not have an assigned IP address. This condition is known as an unnumbered connection. While Windows Server 2003 VPN routers support unnumbered connections, the dynamic routing protocols included with Windows Server 2003 do not work over an unnumbered connection. If you are configuring a static pool of addresses, there might be additional routing considerations. For more information, see the Site Network Infrastructure section later in this chapter.

We become authorities and experts in the practical and scientific spheres by so many separate acts and hours of work. If a person keeps faithfully busy each hour of the working day, he can count on waking up some morning to find himself one of the competent ones of his generation. William James
