In this post we will simulate two different betting tactics for the game of roulette. A martingale is a system of bet that gives the player an advantage that ensures gains.
Of course a working martingale does not exists in casino games but a lot of people still believe that the double bet on lost tactics work.
Let’s find out.
We are using Apache Camel to perform most of our ETLs. We are also using NodeRed for small things. For WebSphere MQ, I don’t think that it is possible to connect to the MQ using the IBM native protocol via NodeRed. So we will do this with Camel.
Version 6.3 is out and it includes a lot cool new features.
ElastAlert is a very nice package that can be installed on top of the ELK stack. It is a free replacement of the X Pack watcher product. The basic idea of the package is to use rules defined as yaml file in order to describe each alerting rule. You will find a nice introduction of the package possibilities here.
We already saw that we can monitor Docker via the Elastic Stack in this previous post. In this post we will update the monitoring script in order to also store the docker events in Elastic Search.
Elastic Search released the version 6.1 of its stack, and once again there are a tons of good new things but this is once again a disappointment for developers writing plugins for Kibana. Once again the compatibility is broken and the code has to be changed. This is painful and I stopped writing plugins for it. I will probably still port the traffic lights plugin for it. (I already have 3 different versions of it, one per Elastic flavour)
We already made a few blogs on Cassandra and Kairos DB. Unfortunately, the recipes used to build the cluster via docker-compose are no longer working with new versions of docker. You will find below a working docker-compose using version 3 of the docker-compose system that builds a three nodes Cassandra cluster.
Using python in amazon web service lambdas can be tricky in the following scenarios.
For the first topic it is still possible to develop on your laptop and to send the lambda via s3. For dependencies with binaries you have to work with a real ec2.
Personal VPNs can be really useful in the following scenarios:
