By Franck Pachot . You may wonder what I’m doing with those technologies that are completely different from what I usually do. I’ll detail in a future blog post but the idea is giving a short introduction to databases to students at https://powercoders.org/, a coding academy for refugees in Switzerland. They install MAMP (My Apache – MySQL – PHP) during their curriculum for website development, and then I’ll use this environment to teach data modeling…
By Franck Pachot . If you want to play with OpenShift on your laptop, you can, in a Virtual Machine. I have VirtualBox installed on my laptop. I’ll install Minishift here, which will create the VM to run OpenShift with few simple commands only. On Linux you can refer to Daniel’s post. Here is the Windows version. Oh, and Daniel did that to run Postgres but my goal is to run an Oracle container of…
As you know, foreign keys establish a sort of relationship between 2 tables. MySQL requires InnoDB storage engine to support foreign keys. In our example, we have the following parent table in a MySQL 5.7.21 server: mysqld3-([email protected]) [sakila]> show create table actor\G *************************** 1. row *************************** Table: actor Create Table: CREATE TABLE `actor` ( `actor_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT, `first_name` varchar(45) NOT NULL, `last_name` varchar(45) NOT NULL, `last_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON…
Disclaimer: This will not be a technical post at all. The goal is to provide a short overview of what we did in 2016 and what we plan to do in 2017 when it comes to our Open Infrastructure division. We’ll start with a few figures then look at the events we did and some of the projects we completed in 2016. Here we go …
