Complete Megalist: 25 Helpful Tools For Back-End Developers

 

The website or mobile app is the storefront for participating in the modern digital era. It’s your portal for inviting users to come and survey your products and services. Much attention focuses on front-end development; this is where the HMTL5, CSS, and JavaScript are coded to develop the landing page that everyone sees when they visit your site.

 

But the real magic happens on the backend. This is the ecosystem that really powers your website. One writer has articulated this point very nicely as follows:

 

The technology and programming that “power” a site—what your end user doesn’t see but what makes the site run—is called the back end. Consisting of the server, the database, and the server-side applications, it’s the behind-the-scenes functionality—the brain of a site. …

DbCharmer 1.7.0 Release: Rails 3.0 Support and Forced Slave Reads

This week, after 3 months in the works, we’ve finally released version 1.7.0 of DbCharmer ruby gem – Rails plugin that significantly extends ActiveRecord’s ability to work with multiple databases and/or database servers by adding features like multiple databases support, master/slave topologies support, sharding, etc.

New features in this release:

  • Rails 3.0 support. We’ve worked really hard to bring all the features we supported in Rails 2.X to the new version of Rails and now I’m proud that we’ve implemented them all and the implementation looks much cleaner and more universal (all kinds of relations in rails 3 work in exactly the same way and we do not need to implement connection switching for all kinds of weird corner-cases in ActiveRecord).
  • Forced Slave Reads functionality. Now …

Adopting RAD in the Enterprise: The 14 Biggest Misconceptions

Rapid Application Development (RAD) is a way of developing computer software applications with less effort than the traditional means.

RAD tools focus on providing code generation and automated testing capabilities with the use of convention over configuration to provide a streamlined workflow to create applications.

Even with the most advanced and easiest to use RAD tools, there are times which the traditional enterprise and the business software development vendors which are having their own implementations and in-house built frameworks are continuously refusing to adopt them.

Most of the misconceptions on the RAD are based on FUD (Fear, Uncertainty and Doubt) which has been created around the internal complexity of the RAD tools.

Ravelry Runs On – 2010

I guess that it’s time for the 3rd annual “Ravelry Runs On” roundup. The last two were in March 2008 and March 2009.

This year, our traffic increased by 50% to 5,000,000 page views and 15 million Rails requests per day. We made very few changes to our architecture in 2009 but we did add a new master database server after our working set of data outgrew our memory and IO capacity.

This summary is more detailed then the last two and I’ve broken it up into rough sections.

Physical Network

We own our own servers and colocate then in a datacenter here in Boston. The datacenter provides us with a cooled half cabinet, redundant power, and a blend of premium (Internap, Savvis) bandwidth. We do the rest.

I use …

SAP as a case study for open source engagement

There was some incredulity expressed yesterday when I suggested that SAP is a great case study on the way in which proprietary companies have engaged with open source.

To be clear, I was not suggesting that SAP is, or should be considered, an open source company, but based on our understanding of SAP’s changing strategy with regards to open source software it represents a good case study on how proprietary companies have learned that it is in their best interests to contribute to open source software projects.

Jay and I had the opportunity yesterday to speak to Claus von Riegen, SAP director of technology standards and open source, and Erwin Tenhumberg, SAP open source program manager. Our formal …

Eleven Open Source Cloud Computing Projects to Watch

Last month cloud computing and systems management expert John Willis published his best of Cloud Computing for 2009 list he calls the Cloudies.  I am not an expert on the latest developments in cloud computing so it was nice to get a list of the best (in his expert opinion) cloud computing tools. I was especially interested in the latest open source software and I did a little research on each of these projects to see if they had active development mailing lists, regular releases  and a real community behind …

Hidden Features Of Perl, PHP, Javascript, C, C++, C#, Java, Ruby, Python, And Others [Collection Of Incredibly Useful Lists]

Introduction

StackOverflow is an amazing site for coding questions. It was created by Joel Spolsky of joelonsoftware.com, Jeff Atwood of codinghorror.com, and some other incredibly smart guys who truly care about user experience. I have been a total fan of SO since it went mainstream and it's now a borderline addiction (you can see my StackOverflow badge on the right sidebar).

The Story

Update 6/21/09: This server is currently under very heavy load (10-200), even with caching plugins enabled. Please bear with me as I try to resolve the situation.
