Last weekend, I visited the PHPBenelux Conference 2018. I experienced a very well organized event with a wide range on interesting topics. As expected there were many PHP focused sessions like "Advanced debugging techniques" (Patrick Allaert), "How PHP ticks" (Sara Golemon) or "Disco – A fresh look at DI" (Stephan Hochdörfer). But also broader issues which are interesting, too. I visited "Go for PHP Developers" (Terrence Ryan) and "Learning Machine Learning" (Joel Lord) and many more. Besides, the official talks there was always an opportunity to have interesting conversations or challenging some fun games. It can only recommend to visit the tenth jubilee next year.

While working on this prooph components powered API, I realized it would make sense for our mobile client to know when data changed on the server-side without constantly pulling all data from the API and comparing it locally. In a "traditional" application I would have used a checksum mechanism - e.g. creating a checksum of all the data in the datastore - but with an event sourced application this is no longer needed as we can simply rely on the timestamp of the last event happened to know if things have changed.

A while I ago I covered the upsert feature PostgreSQL introduced with version 9.5. Back then I showed you how to make use of upsert with one field - the primary key - as conflict target. In a recent attempt to modify the upsert logic to take 2 fields into account I tried to add the additional field to the conflict target:

As it seems there is no out-of-the-box way in Sencha ExtJS to provide a configuration based on the build environment (development, testing or production) to your application. Since you need at least different urls for your proxys, it makes sense to have a mechanism in place that would generate the respective configuration for you. This is our solution for the problem.

We are running Rancher in combination with the in-built load balancer HAProxy. For each of our customers, our application is provided as a single container, many on the same physical server instance. Each of the customers' applications can be accessed via different URLs, so the usage of the HAProxy as the routing component part of the load balancer makes sense.
