MySQL 5.6: single-threaded performance regressions
I ran single-threaded performance tests to compare MySQL using releases 4.0.30, 5.0.85, 5.1.63 and 5.6.11. On my simple tests 4.0.30 is almost 1.5X faster than 5.6.11. I think it is important to reduce these regressions. Maybe this is an area in which the forks (MariaDB, Percona) will lead the way? I previously opened bug 68825 for this and will update it with the results I report here. Peter and I have written about this previously.I used most of the advice from a previous blog post to build…

Real Time Chat With NodeJS, Socket.io and ExpressJS
NodeJS gives me the ability to write back-end code in one of my favorite languages: JavaScript. It's the perfect technology for building real time applications. In this tutorial, I'll show you how to build a web chat application, using ExpressJS and Socket.io.Setup EnvironmentOf course, the first thing to do is get NodeJS installed on your system. If you are a Windows or Mac user, you can visit nodejs.org and download the installer. If you instead prefer Linux, I'd suggest that you refer…

Adobe Fireworks Extensions & Commands for Web Designers
Despite last weeks sad announcement that Adobe would no longer be developing it, Fireworks will remain a firm favorite amongst web designers for many, many years to come. I am convinced of it. Yes, there won’t be any more updates, and as time slowly passes users may dwindle, but the large Fireworks community is dedicated and will not go away any time soon. Resources will continue to be abundant, new...

The EXAMPLE storage engine
The Example storage engine is meant to serve mainly as a code example of the stub of a storage engine for example purposes only (or so the code comment at the start of ha_example.cc reads). In reality however, it’s not very useful. It likely was back in 2004 when it could be used as a starting point for starting some simple new engines (my guess would be that more than a few of the simpler engines started from ha_example.cc). The sad reality is the complexity of the non-obviousness of the…

WordPress 3.6 Beta 3
WordPress 3.6 Beta 3 is now available! This is software still in development and we really don’t recommend that you run it on a production site — set up a test site just to play with the new version. To test WordPress 3.6, try the WordPress Beta Tester plugin (you’ll want “bleeding edge nightlies”). Or you can download the beta here (zip). Beta […]

Don't have the right gear? Make it.
I’ve been working on some video tests with the iPhone and I needed to mount it on tripod for some steadier shots. Some folks in the office had good things to say about the Glif from Studio Neat, but the only one we had lying around didn’t fit my phone and sat kinda goofy on our tripod plate. So, I did something I wouldn’t have imagined possible a few years ago. I printed a new one. We got a 3D printer in the office a few months ago. So far it’s been used to make little statues,…

Mass Assignment, Rails, and You
Early in 2012, a developer, named Egor Homakov, took advantage of a security hole at Github (a Rails app) to gain commit access to the Rails project.His intent was mostly to point out a common security issue with many Rails apps that results from a feature, known as mass assignment (and did so rather loudly). In this article, we'll review what mass assignment is, how it can be a problem, and what you can do about it in your own applications.What is Mass Assignment?To begin, let's first take…

How it Works
We have developed links to a range of existing feeds because we found getting up-to-date and relevant news on PHP and Web Development fairly fragmented.
We use an algorithm based around likes and tweets over time to try and rank popular and most recent articles first.
This should keep the news fresh and always changing. We would love to get your feedback on improvements or additions, just let us know here:
