Testing in production: Canary Deployment

Posted on

The canary is a small bird that sings continually. These birds are sensitive to methane and carbon monoxide. Even at low concentrations of excess gases in the air, they can lose consciousness or die. Gold miners and other miners took canaries with them as an indication: while the canaries sing, work can continue, but if they fall silent—it's time to leave the mine due to gas. Miners often sacrificed the little bird to escape.

Until recently, if there was a need to work with TrueType fonts, there were exactly two options: FreeType and stb_truetype. The former is a huge utility, while the latter supports a relatively small number of […]

Java and the JVM remain exceptionally popular, but when dealing with serverless technologies...
