Fit the RXB1 433MHz receiver module to the prototyping shield and connect one of the ground pins (2, 3, or 17) to GND on the shield. Note that even though the module only has a total of 8 pins, the manufacturer numbers them as if the board was fully populated from end to end as a SIP (Single Inline Package) device, so the first four pins from the left are numbered 1 through 4, and the four pins on the right are numbered 14 through 17. Pins 5 through 13 simply don t exist on the package (see Figure 13-7).

On the SparkFun prototyping shield we used for this project, the RXB1 gave us a bit of a problem because it is the equivalent of 17 pins long while the pad area on the shield is only 16 pins long. However, this problem was easily solved by bending pin 17, the ground pin on the extreme right end, up out of the way. Because the ground connection is replicated on pins 2, 3, and 17, we can just use one of the other ground pins instead and leave pin 17 unconnected. Keep in mind, though, that sometimes there is a good reason for radio-frequency devices to provide several ground connections such as to squelch internal ground loops. Leaving the extra ground pin unconnected could marginally decrease the sensitivity of the receiver, but in our testing it worked just fine with only one ground connection. The RXB1 receiver is a 5V module and pulls a tiny 3mA in operation, so connect either of the VCC pins (4 or 14) directly to the +5V connection on the shield. On our prototype we used pin 4. Also install the 100nF monolithic capacitor between the adjacent GND and VCC pins (3 and 4, respectively) as a decoupling capacitor to help keep the supply rail clean as discussed previously. In Figure 13-8 the smoothing capacitor looks like a tiny yellow egg on the left.

Separating good from bad suggestions can sometimes be difficult. For example, the MPlayer project, which provides an open source movie player and encoder written in C, was advised to take advantage of multicore processors and rewrite its code to be multithreaded. This looks like a reasonable piece of advice. With two cores, the compression speed could be doubled. Also, these days almost everyone has a multicore processor; if not today, almost everyone will have one in the future. Still, the project refused to follow that advice. No wonder, because even the single-threaded version of MPlayer had a hard time avoiding crashing. With multithreaded code, this would have been even more difficult. In my opinion, the team was right in refusing to start exploiting multicores, even though they risked a potential fork of their project. That s exactly what happened: fans of multithreading created their own project, forking the MPlayer code base. As far as I can tell, after a few years, the original MPlayer is still alive, while I cannot find any information on the fork.

your application. The hacker exploits the fact that because the HTTP requests are coming from the user, many applications allow modification or deletion of content. Additionally, it s generally good practice to require POST for any operation that alerts or deletes data on the server. The HTTP specification states that certain methods, including GET, should be considered safe and generally should not have side effects.

Figure 13-8 RXB1 receiver mounted on shield To keep things neat, we also installed a PCB-mount header for the antenna connection, visible at the extreme left in Figure 13-8 You don t actually need to do this, and you could choose to solder the antenna directly to the board if you prefer Next install the debugging LEDs and their dropper resistors The green LED connects to Arduino digital I/O pin 6, and the red LED connects to I/O pin 7 Install the two LEDs on the shield and connect the anode (longer) leads to +5V The other side of the LEDs needs to be connected to Arduino pins 6 and 7 via 680R resistors to limit the current through them, so solder a 680R resistor between each of the cathode (shorter) LED leads and the respective I/O pads on the shield.

As usual, a good decision is one that reduces time to market and lowers cost of ownership Nevertheless, if you have an API and someone asks you to make a change, you are usually not motivated by time to market Your API is already on the market Unless the requested feature is something that everybody wants, you don t need to hurry The only concern is the total cost of ownership If you accept the patch, you ll become its owner Potentially that will mean that you ll spend too much time or energy maintaining it What could be the reason for this risk You might accept a buggy patch, one that doesn t live up to its promise This risk cannot be fully eliminated.
