Figure 6-4. Simple End-Of-Line resistor with normally-open contacts Many sensors such as passive infrared (PIR) motion detectors include internal tamper switches that detect if the case is open. Once again, these are typically N.C. connections that go open-circuit if the case is opened. A simple way to incorporate a tamper switch is to wire it in series with the line, so that if either the sensor is triggered normally or the case is opened, the line will go open-circuit and the alarm will be tripped. This is a bit of a naive approach, though, because it can t detect tampering while the alarm system is disarmed. In a situation such as a retail shop a motion detector will be regularly tripped as customers walk around, and the alarm panel will ignore those events because it s in a disarmed state. If a customer starts taking a PIR apart while nobody is looking, the alarm system won t be able to tell because, as far as it knows, it s simply motion being reported by the sensor, which of course it ignores. The customer could then bypass the sensor within a few seconds just by shorting across the N.C. output terminals, putting the cover back on, and walking away. The sensor will appear to still be functioning normally, but later when the shop is closed and the security system is armed, the PIR will fail to report movement. The most common way to avoid this particular type of attack is to wire the tamper switch separately and run it on a special input to the alarm panel that is active all the time, even when the system is disarmed. Each sensor then has two output pairs: one for the regular sensor output that is only acted on

I ve intentionally used the word future, as I am not aware of any language or system that can provide that functionality right now The most that you can find now are homemade systems that help with various aspects of the API design, but there doesn t seem to be any other general solution Some parts of the solution should be in the compiler, or at least reflected in the sources, and processed by some annotation processor later For example, it should be possible to tell the compiler that when you compile with JDK target milestone 15 no methods and classes introduced in subsequent Java releases should be available This should work for any library, not just rtjar The solution is easy, if we can identify the state of an API in a particular version.

The single most important feature of QuerySet is that it s lazy. Initially, it doesn t do anything except make a note of what query it s eventually supposed to execute in the database, which is why you can keep chaining extra things onto it to add filtering, a DISTINCT clause, or other conditions. The actual database query won t be executed until you do something that forces it to happen, like (in this case) counting or looping over the results.

when the system is armed, and one for the tamper detection output that is acted on at any time of day or night. The only exception is when the system is not only disarmed but also put into a special maintenance mode so that technicians can work on sensors without tamper switches setting off an alert. The downside, of course, is that you ve just increased your cabling requirements and, unless you wire all the tamper circuits together and therefore lose the ability to determine which sensor is being tampered with, you ve also doubled the number of input channels required in the panel a very expensive proposition in many cases. But there is a cheap and easy solution that gives you the best of both worlds, and it s the system we ll use in this project. It s called double end-of-line resistors, and it allows you to detect four possible circuit states with just one pair of wires. With this approach, the N.C. alarm output is wired with an end-of-line resistor in parallel across its terminals, and the N.C. tamper switch is wired with another EOL resistor in series with it. They are then both wired together in series to create a circuit that will produce a different resistance for each of four possible states: cable shorted, normal, sensor tripped, and cable cut or tamper activated. In this project we ll use a pair of 4K7 EOL resistors, and combine them with another 4K7 pull-up resistor at the Arduino and a 1K resistor in series with the sensor line at the Arduino end (see Figure 6-5).

For example, our libraries and their APIs could annotate each class, method, and field with some @Version(14) attribute If the compiler paid attention to this attribute and ignored everything newer than the version of library you want to compile against, this should generate a not found error Of course, this would require that each element visible in the API be annotated with the @Version attribute This means that the packaging and versioning becomes part of the language That is a significant mental shift that no compiler guy I ve spoken with has been ready to make I know language designers have thought about modularity However, that is a modularity created for the Modula programming language back in the 70s That kind of modularity solves how you can compile the program part by part, module by module, but it doesn t prescribe what should happen if one part changes.

Figure 6-5. Double End-Of-Line resistors connected to an analog input Looking only at the right half of the circuit for now, you can see that the resistance across the sensor output wires can be one of the four different values shown in Table 6-1. Table 6-1 Sensor resistance in various states

Wire shorted. Alarm to be activated unless in maintenance mode. Normal. Sensor tripped. Alarm to be activated if armed. Wire cut or tamper detected. Alarm to be activated unless in maintenance mode.
