Mike Perkins IACP Product Introduction Security By Mike Perkins I just spent the last three days at the IACP show in Denver — the annual conference and expo for the International Association of Chiefs of Police. For anyone who was once a 12-year-old boy, IACP is about as cool as it comes because there are all sorts of cop paraphernalia on display — from… View Article Details
GCC’s Unhelpful Error Messages Software Development By Ben Mesander Something must be done about the obtuse error messages issued by the GCC compiler, particularly when using C++ and STL classes. Take this, for example, which is the output I got recently after a one-line change: ‘std::_Rb_tree_iterator<std::pair<const unsigned int, EMMServer::EMM> >’ to non-scalar type ‘std::_Rb_tree_iterator<std::pair<const unsigned int, std::map<short unsigned int, EMMServer::EMMSource, std::less<short unsigned int>, std::allocator<std::pair<const… View Article Details
Howdy Pierce Why is the Compact Disk Sample Rate 44.1kHz? Audio By Howdy Pierce During a recent conference call discussing audio sampling rates, the question came up: Why do CDs use a sampling rate of 44.1 kHz? The 2 Most Common CD Sampling Rates: 44.1kHz & 48kH First, a little background: When you sample an audio waveform, you have a choice as to how many samples you take per… View Article Details

WebOS List Formatters Software Development By Chad Scates Here at Cardinal Peak, we’ve been doing quite a bit of development on webOS, Palm’s new operating system for smartphones. WebOS is based on Linux, and it relies heavily on web standards like HTML, CSS, and JavaScript. It’s a great programming environment, but since it’s also rather new, there’s a lot of tribal knowledge still… Details
Howdy Pierce The Importance of Encrypting Video Over IP Video By Howdy Pierce I just read a report of a new IP security vulnerability being demonstrated today at the DefCon hacker’s conference in Las Vegas. The new hack has two components: 1. The attackers are able to view video being streamed across a network, and 2. The attackers are able to use a man-in-the-middle attack to insert video controlled by the attacker to a video decoder somewhere on the network. The linked video shows viscerally how an attacker could foil a security/surveillance video system — a modern-day Thomas Crown Affair. Details
Mike Perkins Power Measurements With the DFT Signal Processing By Mike Perkins Many of the systems we work on here at Cardinal Peak employ analog-to-digital conversion in one form or another. It seems like almost invariably some analog signal needs to be digitized or “sampled.” Sampling is the process of periodically looking at an analog signal at some sample rate, and then converting each measured value into… View Article Details
