Interviewer: Do you agree with the Model-View-Controller pattern?

Candidate: In what respect, Charlie?

Interviewer: The Model — what do you interpret it to be?

Candidate: Controlling the view from the model, Charlie?

Interviewer: No, the MVC software architectural design pattern widely used in various web development frameworks.

Candidate: … I believe that design patterns are designed to rid us of the burden of reinventing the wheel over and over (…and other such generic drivel).

Interviewer: (closing the candidate’s file and marking it with a red X) Thanks for your time. We’ll keep your resume on file for six months.

Via Ajaxian, Kris Zyp introduces the Dojo Cross-Site XHR Plugin registry

In typical Dojo fashion, it tries the best and most robust methods but allows you to fall back to the basics where necessary, and anticipates the standards currently in development in order to make future transitions minimal.

Great news!

Yesterday I received my (complimentary) copy of Douglas Crockford’s new book Javascript: The Good Parts.

I read it cover-to-cover in a couple of hours. I’m sure I will re-read it cover-to-cover multiple times before I manage to absorb the full import of much of it.

This book is not about the browser, it’s not about Ajax, it’s about a language. It is not a cookbook with recipes, it is a book about the art of cooking that explains what the best available ingredients are and how best to apply them. It may prove to be as central to our understanding of Javascript as K&R is to C, or as the Camel book is to Perl.

I highly recommend this book to anyone who wants to learn how to properly use this most fascinating and important language.

In passing during a rant about the trajectory of ethics in the field of technical book publishing, Jem Matzan accuses the book Enterprise Ajax of being simply a vehicle to shill Nitobi, the company founded by the authors. No supporting commentary or links, just a broadside blow, in a rant about ethics no less.

I was the technical reviewer on that book and I couldn’t disagree more. I found it to be a well-presented book full of technical and business value that didn’t push specific vendor solutions or dwell unduly on the authors’ business.

You have to get over 400 pages into the book before it gets into case studies that could be construed as promoting their own services, but even then the technical value far exceeds any horn-blowing.

I’d be glad to hear from Jem how I’m wrong and have him show me all the examples of shameless shilling that he perceives, however he doesn’t make it obvious how to contact him to engage him about his reports, and even if I were to chase up his contact info, the resulting email conversation wouldn’t help to clarify his meaning to those who might take it at face value.

It’s a two-way web here though, so leave your comments. Have you read the book and come to the same conclusion? Am I wearing my tech blinkers and missing all the marketing cues?

Michael O’Connor Clarke wishes himself a happy seventh blogday, having been blogging since March 1st, 2001.

I’m only a day younger, having stumbled into the light on March 2nd of that same year.

Things have evolved considerably since then and I’m blogging a lot less now, but it’s quite a milestone all the same.

After a long stretch of successfully avoiding getting too involved with development on a Microsoft platform, I find myself taking on the day-to-day development, debugging and support of some IIS/.NET-based applications. The apps themselves are well designed, I’m content enough to deal with C# and .NET in the scheme of things.

When it comes to interacting with the server to do any configuration, maintenance, monitoring or debugging, however, I find myself cursing more often than not.

On this one particular server, I install the .NET runtime, SQL Express, TekRADIUS, and then notice that IIS is not installed, so I install it. It will serve static pages but not .NET pages. The logs didn’t tell me anything – no indication that an access attempt was made or rejected. It takes me nearly a day to figure out that it won’t talk properly to .NET until both IIS and .NET are completely uninstalled and then reinstalled in a different order. There’s no “fix it with this config tweak”, it’s just “reinstall in a different order and it should work”. Magically, it does, but I’m not confident that it’s more than a coincidence. I’d rather know why, however, I don’t care to spend another day of this project plan on it.

I have a 30 megabyte server log file to inspect. Let’s see, what tools does Win2k3 server provide for me to look at it? Umm….. notepad. But not until I add it to “send to” or associate the file extension. How do I filter it? I can use “find” at the commandline and redirect into another file, but find is practically useless with no regular expressions. “More” only pages through the output in one direction. Where’s “tail”? I have to repoen the 30M file after I try another server access and then want to see the next entry? What do people in the W2k3 world use instead of “tail -f”? And what about log rollover? Is there nothing built into W2k3 server to manage the zipping, archiving and deletion of log files? It seems not. Any tools you will need to manage this baby don’t come with it, you have to get them yourself and install them. The tools supplied fall wayyyy short of being useful. Try to use the Event Viewer to filter by regular expression into a file that you can then manipulate further. You have to write your own programs to do stuff like this or get third-party tools. You can install Powershell, which is a great improvement, but my solution is just to install UnxUtils and get right down to being productive.

I want to use SSL. I set the SSL port, restart the instance, try https://localhost – nothing. Look at logs, nothing. Turns out I have to have a cert in place before it will work, not that the server was going to give me any hints. I had assumed a self-signed cert would be there by default. I have to find and download an SDK and follow a dozen-step process to build a cert, then import it into the cert store.

The entire configuration is a collection of settings that are entered or inspected one-by-one by tediously navigating the management GUI to varying depths of dialogs. When I have my config together and I want to set up the next server, I don’t provide it with a monolithic settings file from my reference system, I have to tediously make each click and entry, then backtrack and debug when I inevitably miss something critical. I understand the typical approach is to build a reference system and clone it, then mess with the machine IDs. What a palaver.

When I finally get through a marathon session of setting up a Windows server “just so” to make my application work, it’s like I have created a finely balanced stack of Jenga blocks from which I back away slowly on tiptoe, praying it doesn’t tumble. I’ve got very little confidence that fixing anything will be an excercise in logic and deduction more than having to know some obscure incantation or uninstalling components wholesale and reinstalling and reconfiguring them.

I’m afraid I find it really difficult to understand how any Windows server can be considered a serious business tool when it’s shipped without even the most rudimentary tools to effectively inspect, monitor and maintain its operation.

The state of the art of web development has taken a leap forward recently with the announcement of Jaxer, Aptana‘s new Javascript-on-the-server environment which allows you to write a web app as a single item, without having to devote much time and brainpower towards most of the distinction between what is run at the server and what is run at the browser.

My application stack diagram from the Ajax Summit back in 2005 shows how early Ajax applications had to take it upon themselves to perform the drudgery of remote procedure call invocation, encoding and packaging, the transport layer, decoding, dispatch and then the encoding, packaging, sending, receiving, decoding and consumption of the response package.

Three years later, Aptana’s diagrams show how far they have brought us forward with their advanced client libraries and server technology that have abstracted away all of the remote procedure calls and data marshalling, making the gap between client and server much, much less of a chasm.

Jaxer is not some net new unknown – it’s built on the Mozilla Javascript and rendering engine. It’s open source licensed under the GPL. It’s backed by Aptana, whose eclipse-based IDE tool is a well known market leader, and whose Advisory Board is absolutely packed with the very top names in the Ajax sphere.

As John Resig points out in his coverage of Jaxer, this is an exciting piece of technology, and I would go as far as to say it has the potential to be a game-changing development.

I was at the TSOT Ruby/Rails Project Night last night. It was a great gathering, and I was treated very well by the hosts – they even brought in Guinness for me!

The soiree was at the new TSOT offices in downtown Toronto, on the 11th floor at 151 Bloor West, with a beeeautiful bird’s-eye view of the Royal Ontario Museum. Last time I was there, CEO Kris White showed me around the unfinished space, but now it’s finished and filled with staff and desks and computers and books and, well, you name it.

Inspired by my pal Joey’s Office Desk posts, I figure it’s time to give you a peek into my basement home office.

Here’s a panorama of the computerized half of my L-shaped desk. I control all of the computers on it from the Dell’s keyboard and mouse, using Synergy, which allows me to pan the mouse right across, from Linux to XP to Linux to Mac, transferring keyboard control as I go, even cutting and pasting text between any of the machines.

From left to right:

• Dell B/W Laser Printer
• Speaker Phone with Call Display
• Toshiba Satellite Pro 4260 pIII 550 running Xubuntu
• Dell 9200 Centrino Core Duo T2600/2.16GHz 1920×1200 running XP Media Center
• ASUS Eee PC 2G Surf running Xandros Linux – on top of external USB2 DVD writer
• 8-port switch
• Mac Mini Core Duo running OSX10.4 just under left of monitor
• Toshiba A10 P4 2GHz running XP Home – the display died, so I ripped it off completely
• On the monitor you see the Mac desktop, with a VNC window into the Toshiba A10, and a TV window from the EyeTV USB tuner
• A/B switch to switch between Mac and Toshiba A10.
• Speakers either side of monitor (subwoofer at floor level)
• Mac keyboard in sliding tray behind the chair
• Epson Stylus Color Inkjet Printer

What you don’t see in the next room is my server pc, a Compaq EVO small form factor with three 250G drives, which is also hooked to my home theatre, which uses an Optoma projector and 7’x5′ screen hooked to HD PVR, DVD, 5.1 audio and the Wii (at that size, it’s like having a bowling alley in your basement!). My daughter’s desk has a Dell Optiplex P4 1.8GHz with XP Home and a scanner, the kitchen has a Toshiba P4 2.8 Laptop running XP Pro, there’s a 160G NAS device at the other end of the house, and the Router is a Linksys 54G running the Tomato firmware.

My newest machine is the Asus Eee. I got the lowest model – $299 for the Blush Pink 2G Surf, with 512M RAM, 2G solid-state flash disk, no camera. When I’m in the office, I use it as a handsfree phone using Skype – at 2 cents a minute for calls to landlines in North America and Europe, it’s a great deal.

The Eee is a fantastic computer, well designed, well implemented. Best out-of-box experience I’ve EVER had. I’m looking forward to using it as a road warrior machine, for hacking, and for presentations. Those guys with their little 13 inch Apples will have nothing on me – I’ll stun them with my sheer nerdliness. With that in mind, I’ve already done a case mod to fill them all with fear and envy.
