In my last article, I started discussing how to optimize a Web application, looking at the different aspects of an app and where the slowness might come from. more>>

What Does "Fast" Mean?

Good news! One of my clients is launching a new marketing campaign, which we expect will make the business even more successful than before.

Bad news! This means our Web application, which has existed for some time on a fairly simple infrastructure, and which has handled a steadily growing number of users, now (we hope) will need to deal with a massive spike in users. more>>

Use Your Database!

I love high-level, dynamically typed languages, such as Python, Ruby and JavaScript. They're easy—and even fun—to use. They let me express myself richly, and they lend themselves to code that easily can be reused and maintained. It's no surprise that interest in such languages is on the rise, especially when creating Web applications. more>>

Django Models

In my last article, I continued looking at the Django Web framework, showing how you can create and modify models. As you saw, Django expects you to describe your models using Python code. The model description is then transformed into SQL and compared with any previous version of the model that might have existed. more>>

Firefox Security Exploit Targets Linux Users and Web Developers

Through the years, Firefox has enjoyed a reputation as one of the most secure Web browsers on any platform, and it's the default browser for many Linux distros. However, a security exploit appeared this week that has shown users they can't afford to be complacent about security. more>>

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

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>>
