The quest begins for Python3 modules

Although it has been released for a long time, it seems that some modules for Python3 are still a bit difficult to find.
The first time I had this impression was looking for a connector between Python3 and MySQL. The module MySQLdb that I always used with python2 is not available for version 3 of the language and it's not clear if it'll ever be in the future. In the Internet you can find some alternatives, but for many of them it's not clear which is the degree of completeness (or it's clear that it's not so high) and support.
I came to the conclusion that the more reliable candidate is oursql. The other two modules that are compatible also with Python3 are: PyMySQL and MySQL Connector / Python (the latter is pure Python, so it does not need to link to MySQL client library).
Besides, SQLAlchemy always proves exceptional because it is able to use all the modules to connect to the database.

Pairing the Raspberry Pi 3 with your Playstation 3 controller

While setting up the MAME emulator on the Raspberry Pi 3 I decided to experiment with the PS3 controller trying to pair it with the RPi. I found a useful guide here: http://holvin.blogspot.it/2013/11/how-to-setup-raspberry-pi-as-retro.html At section 4 the author describes how to compile sixpair utility, test that everything is working and compile the QtSixA tool. But there are some differences to be noted when working with the Raspberry Pi version 3. First, and most obvious, of all: the RPi 3 has already a Bluetooth device built in, so you don't have to plug a dongle in it, and it's compatible with the PS3 controller. 1. Sixpair The sixpair utility succeeds in coupling with the controller. But to test that it's working I had to test the js1 joystick port, and not the js0 as stated in the guide; so the actual command is: jstest /dev/input/js1 2. QtSixA The QtSixA download link must be changed, because the one shown doesn't compile with the latest

JSON Web Token Tutorial: An Example in Laravel and AngularJS

With the rising popularity of single page applications, mobile applications, and RESTful API services, the way web developers write back-end code has changed significantly. With technologies like AngularJS and BackboneJS, we are no longer spending much time building markup, instead we are building APIs that our front-end applications consume. Our back-end is more about business logic and data, while presentation logic is moved exclusively to the front-end or mobile applications. These changes have led to new ways of implementing authentication in modern applications. Authentication is one of the most important parts of any web application. For decades, cookies and server-based authentication were the easiest solution. However, handling authentication in modern Mobile and Single Page Applications can be tricky, and demand a better approach. The best known solutions to authentication problems for APIs are the OAuth 2.0 and the JSON Web Token (JWT). What is a JSON Web Token? A JSO

Software Release Management For Small Teams

Formalizing The Release Management Process (If There’s Any) In some team configurations, especially ones that are found in startups, there are no DevOps, nor infrastructure engineers, to provide support when releasing a new version of the product. Moreover, unlike large bureaucratic companies with defined formal processes, the CTO or Head of Software Development team in a startup is often not aware of the complexities of the software release management process; a few developers in the company may be aware of the complex details of the process, but not everyone. If this knowledge is not documented thoroughly , I believe it could result in confusion. In this article, I’ll try to provide some tips about how to formalize the release process, particularly from the developer’s point of view. Enter The Software Release Checklist You may be familiar with the idea of a checklist for some operations, as per the Checklist Manifesto , a book by Atul Gawande. I believe a formal release proc
