I recently led a talk on distributed machine learning and some optimizations. Slides can be accessed here.

Overview One of the poweful features of modern C++ is move semantics. So, what is move semantics? Move semantics makes it possible for compiler to replace expensive copying operations with less expensive moves.

One thing about C++ that attracts me a lot is that it gives me control over the program to a great extent. Therefore, I am starting an article series on why C++ is efficient from the implementation perspective.

The following script was adapted from https://gist.github.com/ryin/3106801, with some improvements and broken link fixes. #!/bin/bash # Script for installing tmux on systems where you don't have root access. # tmux will be installed in $HOME/local/bin.

Recently I came across an interesting topic on memory access optimization named data alignment. I know that struct can be seen as public class, and the performance of struct of array is better than array of struct thanks to contiguous memory.

free is a command which can give us information on available RAM in Linux machine. This post will summerize the usage of free command and how to interpret the output.

Lately I’ve been admitted as intern at a tech startup to work on a SDK. To begin the development, my first task is to get my development environment ready. This job allows me to take time to reflect on what I’ve done to make it cozy, and how to make it better or even streamlined.

Recently there was a strange error during code compilation. The compiler complained that the modified date is ahead of current time for some objects, thus it cannot figure out the correct dependencies.
