Django Models and Migrations

In my last two articles, I looked at the Django Web application framework, written in Python. Django's documentation describes it as an MTV framework, in which the acronym stands for model, template and views. more>>

Django Templates

In my last article (February 2015), I explained how to create a simple Django project ("atfproject") and inside that, create a simple application (atfapp). The application worked in that if you went to the URL http://localhost:8000/hello/Reuven, you got the text "hello, Reuven". more>>

Drupageddon: SQL Injection, Database Abstraction and Hundreds of Thousands of Web Sites

Drupal is a very widely used open-source content management system. It initially was released in 2001, and recent statistics show Drupal as the third-most popular content management system, with just less than 800,000 Web sites utilizing Drupal as a content management system. more>>

JavaScript All the Way Down

There is a well known story about a scientist who gave a talk about the Earth and its place in the solar system. more>>

Users, Permissions and Multitenant Sites

In my last article, I started to look at multitenant Web applications. These are applications that run a single time, but that can be retrieved via a variety of hostnames. more>>

Multitenant Sites

For some time now, there has been tremendous growth in the world of Web applications. It's quite amazing to see what you can do just via a Web browser—not only can you buy just about anything, but also a growing number of sites offer "software as a service", often abbreviated as SaaS. The idea is that in exchange for a monthly service fee, you get access to a service. more>>

February 2015 Issue of Linux Journal: Web Development

Under Construction

I think it was in the late 1990s, possibly into the 2000s, when it was common to put a cutesy graphic on the bottom of your Web page letting everyone know your site more>>

PostgreSQL, the NoSQL Database

One of the most interesting trends in the computer world during the past few years has been the rapid growth of NoSQL databases. The term may be accurate, in that NoSQL databases don't use SQL in order to store and retrieve data, but that's about where the commonalities end. NoSQL databases range from key-value stores to columnar databases to document databases to graph databases. more>>

Readers' Choice Awards 2014

It's time for another Readers' Choice issue of Linux Journal! The format last year was well received, so we've followed suit making your voices heard loud again. I couldn't help but add some commentary in a few places, but for the most part, we just reported results. Please enjoy this year's Readers' Choice Awards! more>>

Discourse

Back when I started to use the Internet in 1988, there was a simple way to get answers to your technical questions. You would go onto "Netnews", also known as Usenet, and you would post your question to one of the forums. There were forums, or "newsgroups", on nearly every possible topic, from programming languages to religions to humor. more>>

Vagrant

How many times you have been hit by unit tests failing because of environment differences between you and other team members? How easy is it to build your project and have it ready for development? Vagrant provides a method for creating repeatable development environments across a range of operating systems for solving these problems. more>>

Geolocation

There's an old saying in the real-estate business that the three most important things in a property are location, location and location. We can assume this is still true when it comes to real estate, but it also is increasingly true when it comes to Web applications. more>>

TogetherJS

Want to add real-time collaboration to your Web application? Mozilla's TogetherJS is worth a look. more>>

Siege Your Servers!

Setting up Web servers is fairly simple. In fact, it's so simple that once the server is set up, we often don't think about it anymore. It wasn't until I had a very large Web site rollout fail miserably that I started to research a method for load-testing servers before releasing a Web site to production. more>>

Debugging Web Sites

I know, I'm in the middle of a series of columns about how to work with ImageMagick on the command line, but when other things arise, well, I imagine that a lot of you are somehow involved in the management of servers or systems, so you all understand firefighting. more>>
