I'm shopping for electronics lab equipment, and all of the new equipment comes with web interfaces and iPad apps. Even the power supplies. Kids these days are so spoiled.

Interesting talk on choosing the right data structures in C++: CppCon 2014: Chandler Carruth "Efficiency with Algorithms, Performance with Data Structures" . The bottom line is that std::list and std::map are slow.

Makes me wonder if I should go off and implement my own associative data structure.

This is something I've had to train myself to do -- linking to line numbers in specific Github commits rather than a line in the the (ever-moving) current head of a branch.  Didn't know about the "y" shortcut, which will save a lot of clicks.

The first project I'm using C++11 on is a microcontroller. Because that's how I roll.

Note to self: don't try to run ROS on a big-endian machine.

New favorite C++ toy: boost::program_options.

It makes parsing command-line arguments sane in C++

Austin- Hendrik has been trying to convince me to use gflags. It's really great for basic things, and I love that you can declare params in libraries and have them pass through to executables that use them. Unfortunately it doesn't seem you can do some fancier tricks like variable length lists of arguments and such, which I use a lot.

I've been coming here for ice cream for 10 years. All of their flavors are delicious, but be sure to try the Lavender and Olive Oil if they're in season!
