Two “Scoops” of “Bugs”

Fri, 30 Jul 2010 22:00:11 -0500

I have often said something like “We found a hundred bugs!” Lots of people have heard me say it. Statements like that are very valuable to me. But we should ask some vital questions about them.Consider Raisin Bran cereal. If you lived in America and weren’t in solitary confinement during the 80’s an 90’s you [...]

Codemanship's Code Smell Of The Week - Lazy Classes Part II

Fri, 30 Jul 2010 09:03:33 -0500

Jason Gorman quickly illustrates how to apply the Collapse Heirarchy refactoring to eliminate a lazy subclass

Codemanship's Code Smell Of The Week - Lazy Classes (Part I)

Thu, 29 Jul 2010 07:00:30 -0500

Lazy classes add little value for the maintanance burden they incur. In this example, Jason Gorman illustrates how to safely inline a lazy class into its containing class.

Rackspace Cloud - Outbound Bandwidth Caps, Network Too Slow

Tue, 27 Jul 2010 11:30:28 -0500

Have you seen the network/bandwidth caps that Rackspace places on their cloud servers?

From the Rackspace Cloud Server FAQ:

"Your Cloud Server has a bandwidth cap that is applied in relation to the size of the server. Please note that the bandwidth caps are placed on outbound bandwidth only. Inbound bandwidth is not capped."

WebInject - New Discussion Group Launched

Sun, 25 Jul 2010 14:30:19 -0500

I just started a new discussion group for WebInject: http://groups.google.com/group/webinject

The old forums (http://www.webinject.org/cgi-bin/forums/YaBB.cgi) have been broken for several years. I will leave them up in read-only mode, but some threads are broken and unviewable.

youDevise series on my new blog

Sat, 24 Jul 2010 16:22:32 -0500

I've started a new series on my blog... it's a weekly diary of what it's like to work with youDevise as a developer. I thought it might prove interesting to those considering working there in the future... since they are frantically hiring.

You can read the diary on my new blog.

Wondering why I have a new blog?

Membase Stats Report (Python)

Fri, 23 Jul 2010 17:30:18 -0500

[Membase is a high-performance, distributed key-value database (NoSQL)]

To check operational stats of your Membase server/cluster, you can use the telnet interface (port 11211) and issue the stats command to any individual node:

$ telnet 192.168.12.11 11211
stats

The output is unsorted and a little difficult to read at quick glance.

by Alberto Savoia

I first posted this article a few years ago on the Artima Developer website; but the question of what's adequate code coverage keeps coming up, so I thought it was time for a repost of Testivus wisdom on the subject.

Monitoring Stats From Memcached or Membase (Python, RRDTool)

Mon, 19 Jul 2010 12:01:02 -0500

memcached_stats_rrd.py is a script for monitoring and graphing stats from Memcached or Membase.

Memcached is a high-performance, distributed memory object caching system, and Membase is the related key-value database management system. Both are open source, with packaged/commercial versions distributed by NorthScale. They both use the memcached protocol for communication, so this script will work against a vanilla memcached installation, or against a membase server/cluster.

Codemanship's Code Smell Of The Week - Inappropriate Intimacy

Mon, 19 Jul 2010 06:31:23 -0500

When two classes exhibit an unhealthy fascination with each other's bits, we call the Inappropriate Intimacy. It's essentially bi-directional feature envy. In this video, Jason Gorman demonstrates hot to change a bi-directional relationship into a uni-directional relationship and eliminate the feature envy on both sides.

Sat, 17 Jul 2010 21:00:27 -0500

By James A. WhittakerI've had more than a few emails about "antenna-gate" asking me to comment and suggesting clever, stabbing rebukes to a fallen competitor. I might aim a few of those at my own team in the future, some were genuinely funny, but none of them will appear here. Instead I offer first a word of caution and second a reflection that my Mom used to intone whenever disaster occurred around her. It's called "counting your blessings."

Using JUnit Nested Suites with Selenium RC to simulate TestNG suite and grouping annotations

Sat, 17 Jul 2010 12:00:41 -0500

When I use TestNG for my Selenium tests, I really like the BeforeSuite and AfterSuite annotations because then I can share a Selenium session amongst the tests. With nested JUnit suites I can achieve a similar effect, and I can also go some way to grouping my tests to make it easier to create browser [...]

Codemanship's Code Smell Of The Week - Switch Statements

Fri, 16 Jul 2010 13:30:50 -0500

Switch statements are bad from an OO design standpoint. Not only because they're basically big nested IF statements, but because they have a tendency to grow. A refactored switch statement would exploit polymorphism, which is the OO way to make decisions about how to do specific "stuff" at run time.

Jason Gorman demonstrates how he refactors a simple switch statement into a polymorphic OO solution (like the Strategy Pattern).
