If we interview you here at Cardinal Peak, we're going to assume you're competent to use Google, and we'll give you the benefit of the doubt that you can look up answers to weird corner cases. What we really want to know is how deeply you understand how a computer works.

Aside from the glut of “UltraHD” televisions at CES this year, I saw two other trends that seem noteworthy to me but that have not been highly reported in the tech press: There is a huge number of Internet-connected home sensors of all kinds, and also a much large concentration of smart or connected fitness...

Discover the flaw in Nikon’s image authentication system and the implications for security. Learn why true file integrity relies on more than checksum protection.

Based on a Slashdot link, I read a blog post today about the Oracle/Google lawsuit over Java virtual machine patents. Among the list of software patents that Oracle has decided to sue Google with are two that I’m fairly certain that I wrote prior art for. This was in 1983 or 1984 while I was... View Article

A recent project for a customer was to implement a transport for a real-time signal processing application over Gigabit Ethernet (GbE). The project was especially interesting because our customer’s requirement was for extremely low latency: The transport needed to be able to send replies to incoming packets with a custom EtherType within 74.4 μsec. This... View Article

In an earlier post, I suggested making all your memory allocations go through a single routine, and deletions through another. When you centralize allocation and deallocation like this, you gain a couple of benefits. First of all, you make the memory allocation more explicit, which will tend to make programmers more careful. Second, you can... View Article

Finding memory leaks and other problems in your code can be challenging, but there are tools available to help simplify that process. Remember to add time to your schedule so that you can apply the available tools for finding memory leaks and other problems.

Learn how to prevent memory leaks in C/C++ with Ben's Golden Rule. Follow these steps for effective memory management and ensure your embedded systems run smoothly!

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...
