My latest hybrid app, CoolKids, let you track good and bad actions of your kids to help them in self-improving. I thought it would be nice to share kids achievements with family and friends on social networks, emails, IM, etc. This post shows how I did it.
During the development of CoolKids I discovered a simple trick that can be a great time saver when you are building your app using Ionic Framework and the Crosswalk web view.
In few steps you’ll be able to automate the production of release signed apks of your app, ready to be published on the Google Play Store.
Here is one of those little things that make me love Python: Prints: a 1 2 b 3 4 How cool is that? ;)
Assume that you have a Django project where each user belongs to just one group, say Registered or Admin, but not both.
You want to show a form in your front-end to let Admin users edit the user profiles, where each user profile is made with First name, Last name, Email and the user group.
This task can be accomplished very easily! What you need is a customized ModelForm to add the possibility to edit the user group together with the other fields, and a customized UpdateView to let you set the form initial data for the group field, and to save the changes correctly.
Sometimes it could be useful and elegant to have a Django view responding to more that GET and POST requests, implementing a simple REST interface. In this post I’ll show how you can support PUT and DELETE HTTP requests in Django.
Google Cloud Print (GCP) is a quite useful Google service, allowing you to print in a GCP compliant printer from everywhere and from every device of yours, be it a desktop, a tablet or a smartphone. There are quote a lot of printers out there supporting GCP out of the box, but here I will explain how to turn every Linux supported printer in a fully functional GCP printer. As a bonus you’ll have a cheap Linux based print server in your local network, which is alone a nice thing to have. All this thank to the amazing Raspberry PI ARM GNU/Linux mini PC.
Fast and easy! $ sudo stop mysql $ sudo -umysql mysqld_safe --skip-grant-tables & $ mysql mysql> UPDATE mysql.user SET Password=PASSWORD('newpassword') WHERE User='root'; mysql> FLUSH PRIVILEGES; $ sudo kill `cat /var/run/mysqld/mysqld.pid` $ sudo start mysql Enjoy your new mysql root password!
If you administer at least one Joomla instance you’ll be subject to brute force attacks before or after. Fail2ban is a very nice service written in Python which periodically scans your log files looking for signs of brute force attacks and perform some actions when an attack is discovered. The most common actions is to ban the attacker IP at firewall level and send an email to the server administrator.
Fail2ban comes bundled with filters for many common services (ssh, apache authentication, etc.), but it lacks a built-in Joomla integration. Anyway it’s easy to add a Joomla filter to Fail2ban, here I explain how to do it.
If you like me use sitecopy to easilly maintain remote websites over FTP, you also find annoying that bash autocompletion doesn’t work as expected in Ubuntu 12.04. In this post I’ll show you how to happily solve this issue.
Since some months I’m using Toggl to track my work time, and I find it awesome! Toggl features a very powerful reporting system to have your timesheets filtered in many ways and exported in csv or pdf format, but I did not found the way to have an Excel timesheet as I like it.
But wait! Toggl features a very nice public API to access your time entries (and many more), so I wrote a simple Python script using the wonderful Requests and Xlsxwriter libraries.
