March 29 2014 is Arduino day, also in Labitat. This is a good opportunity to describe my LED-cube: This LED-cube pulls a number of tricks to get the most out of just a single normal Arduino Uno. A meager 16 MHz and 2048 bytes of RAM goes a long way with sufficient ingenuity and creativity.… Continue reading Arduino to the max: 11x11x11 LED-cube

No application changes needed: 10 times faster slave with MariaDB 10 parallel replication
Parallel replication is in MariaDB 10.0. I did some benchmarks on the code in 10.0.9. The results are quite good! Here is a graph that shows a 10-times improvement when enabling parallel replication: The graph shows the transaction per second as a function of number of slave worker threads, when the slave is executing events… Continue reading No application changes needed: 10 times faster slave with MariaDB 10 parallel replication
