To solve a planning or optimization problem, some solvers tend to scale out poorly: As the problem has more variables and more constraints, they use a lot more RAM memory and CPU power. They can hit hardware memory limits at a few thousand variables and few million constraint matches. One way their users typically work around such hardware limits, is to use MapReduce. Let’s see what happens if we...

From first look, Docker has a “logs” command that will fetch the logs from a container. However, using the Docker “logs” command is a little primitive. A better approach might be to run Rsyslog from your container to forward any logs...

After seeing the presentation on Shenandoah at FOSDEM and the source code release announcement I've put together a summary blog post & instructions on how to...
The biggest downside of all new logging tools is that they’re dependant on the data you actually put into the log. To reduce the chances of debugging your code with partial or missing log data, here are 5 things you should be constantly mindful of when logging in production.
In the past it was assumed that the web-based interface was the most important, and often the only, path for a user to access content or a product.
