In this article I’ll explain how to to launch a popup on an external URL (e.g. Oauth login), detect when that popup redirects to a different location (Oauth callback) and access the popup URL param values (e.g.

Ansible is a simple to use but yet very very powerful free software provisioning, and configuration management.
You can use to define in a readable YAML config file with everything you want installed and configured inside the raspberry (list of packages, fstab, crontab entries, samba config, DHCP config, ssh authorized keys, customs scripts..), and just run it.
With one command (ansible-playbook ~/your-config.yaml), Ansible will check your playbook (the YAML file) and install/update what’s missing. This is extremely useful when you want to make a change, and a big time saver if you need to reinstall, upgrade, or move SD card.
Disk Utility on macOS Catalina 10.15.7 does not let you shrink or extend the Bootcamp Windows partition.
There are lots of third party software around, but most of them did not support Catalina OS the time of writing (April 2021).

Java introduced lambda expression too from version 8, with a similar expression syntax, but the difference is that every variable in Java has a type (either native or a class/interface), and everything has to…
Mysql supports a config option called
When enabled (add
/etc/mysql.cnf or any included file from it), Mysql will print all the executed queries into a log file (see the specific documentation of your version to understand where the file will be written based on settings).

The impact of Corona Virus on the low cost airlines
I’ve watched a very interesting short documentary about how low cost airlines work, and how they manage to offer a similar service to traditional flight companies for a lower price. I already knew that the strategy were offering basic service (only stairs to board), and selling things on board, but some other strategies are actually very smart, already existing in other type of businesses.
Low cost airlines buy planes in bunches, getting big discounts. Ryanair once bought 151 planes at once. Having the same plane model also makes it easier…
Amazon, best best online store nowadays, has an incredible amount of items on sale.

The decorator design pattern allows to add behaviour to an object without changing it, by implementing the behaviour in a new object that “wraps” the original one without extending it. Clear advantages are keeping the logic in separate classes, being able to compose them and being able to unit-test them in details.
Let’s take for example a basic URL download functionality. I just want to download an URL from a server and get the content, but I also want to cache the result, and also have a functionality to try again if the network was temporary unavailable.
Placing all this…
Gitlab offers tools to set up a CI pipeline in order to analyze and test your code automatically before merging. I’ll show an implementation for a Symfony 3 and 4 application (or any other framework capable to be configured to run in test mode via an environment variable), with CI pipelines to analyze your code and run test with a dedicated database (dropped and recreated each time)
