Problems with WD Caviar Green SATA Drives

I needed a couple of 1 TB SATA drives to put into external enclosures.

I have found that in many cases MicroCenter offers prices very close to that found on Amazon, and/or Buy.com. The thing that I really like about MicroCenter is that they actually have knowledgeable sales people. When seeing if the drives that I was looking for were in stock the sales associated told me that I wanted to stay away from any of the “Green” drives. In his experience, not only were they considerably slower (which in this case, didn’t make much of a difference to me) but that their reliability was very poor. The “Green” drives spin at variable speeds so that they will consume less energy. Evidently, the variable speed mechanism hasn’t been sorted out completely and results in catastrophic hardware failure.

bad owner name (check-names) Error in BIND 9

I added a subdomain to a zone file and when I reloaded named I noticed the following error in messages:

Oct 29 09:31:06 master named[28254]: tabordesignbuild.com.db:59: beta_live.sampledomain.com: bad owner name (check-names)
Oct 29 09:31:06 master named[28254]: zone sampledomain.com/IN: loading from master file sampledomain.com.db failed: bad owner name (check-names)

We are running BIND 9 and after doing a little searching it turns out that with the default configuration for BIND 9 underscores are now verbotten.

Evidently, if you need to include an underscore “_” in your domain name you can turn off name-checking but that seems to be overwhelmingly not recommended by the wider sysadmin community.

Marketing Book Review: Purple Cow by Seth Godin

I recently finished reading Seth Godin’s Purple Cow, Transform Your Business by Being Remarkable and would strongly suggest that any business owner, manager, C-Level executive, or marketer read it.

His main thesis is that the marketing paradigm has changed and that instead of trying to market to a broad audience with traditional methods you must position, or change, your brand or company so that it highlights something that is remarkable and targets a very specific niche of early adopters. And that it is the early adopters (people who are open to your message and interested in what you have to say), that will spread the word (or sneeze) about your product.

Godin explains why conventional marketing strategies no longer work. That nobody listens to conventional advertising because they don’t trust it, and they don’t have time to listen to and evaluate messages for products or services that they most likely already have, or are using. His ideas build on those from Crossing the Chasm, The Tipping Point, Unleashing the Ideavirus, and Permission Marketing, and he argues that the only people that are open to new products or services are the Innovators and Early Adopters. And that ideaviruses are the most effective way to spread your message. It is by being phenomenal, and remarkable in some counter-intuitive way that you gain the attention of the Innovators and Early Adopters and that they will be the ones to sneeze your idea virus to the rest of the marketplace.

He includes a wide variety of case-studies and examples and the book is written in a very straightforward and approachable manner.

One aspect of the book that I found amusing was how he weaved his own teachings into it; encouraging people who wanted to be different (the early adopters) to give his methods a try and to share (sneeze) his book with others. Brilliant.

So, does your business have a Purple Cow?? And if so, who are your Interested Sneezers?

On WYSIWYIG HTML Editors and the jQuery.UI web user interface toolkit.

Building advanced web applications and frameworks often involves getting incompatible pieces from various projects to work together cohesively inside a majority of browsers. The more advanced the functionality, the more of a problem this becomes especially when you’re trying to support older and very broken browsers such as MSIE 6.0.

At the present moment, I’m involved in building a substantial ecommerce project with a desktop style interface that includes popup dialogs, drag and drop lists, multiple tabbed interfaces among other patterns. The desktop guys with all of their mature toolkits just don’t know how easy they have it in comparison.

For this particular project, we’re using the jQuery UI toolkit which is excellent. However,sometimes there are conflicts with other projects, such as the Xinha WYSIWYG Htmleditor control we use. Xinha does not like to be placed inside hidden divs. (Google maps has a similar issue as do most more advanced components).

I’ve written up a short summary of a solution to get these disparate pieces working together:

Two Great Lists and Reviews of Flash and Javascript Charting Packages

What follows are links to two different blog articles by Steve Reynolds about both Flash and Javascript packages. The coolest looking package, not just charts is the Raphael Javascript library.

Open Source Flash Charting Package: Open Flash Chart

ofc_logo.pngWe have a client that is in need of some dynamic Flash charts. After some googling I came accross the Open Flash Chart project. It seems to be an active project with a decent following. Moreover, there are a number of other commercial products out there that are using the LGPL licensed code.

It looks to be a fairly mature code base that provides an enormous amount of customization without editing any ActionScript code or recompiling any .swf files. Right now, I’m just struggling with the lack of documentation and it’s just taking a while to figure out the syntax of the php front-end that is provided; through which you can generate the JSON data set that the Open Flash Chart swf reads.

Here are links to the docs and resources that I have found:
