Free Wireless, Good Beer

I stumbled upon an excellent "virtual office" this afternoon. While riding my bike downtown for JUG meeting tonight, I decided to stop at a local restaurant: The HandleBar & Grill. While driving by a few months ago, I noticed a "free wireless" sign, so I figured I'd stop in and check it out. Sure 'nuff - I'm on it right now! Not only is this a good burger joint, but they have some good microbrews too. Better yet, I just noticed it's happy hour. So here I am, sipping on a Fat Tire and working on open source. Life doesn't get much better than this!

A CSS Framework

Mike Stenhouse's CSS Framework seems like it might be a good candidate for inclusion in AppFuse. In his article about this framework, he basically says that there are 6 basic layouts that "cover most of the blogs out there and most of the corporate sites as well". He shows you how it's possible to use a single XHTML page, and use CSS to achieve all of these layouts w/o changing your HTML. This is huge IMO because you can accomplish all the different layouts w/o changing your markup. Very cool. Hat tip to CSS Beauty.

Spring Training in Norway

A week from today, I'm heading to Norway to do some training on Spring. It's going to be a good trip and I have my work cut out for me. I'll be talking about Spring, Hibernate, AppFuse, Acegi Security as well as Ajax and Spring Web Flow. I'll also be presenting at the two JUGs in Norway:

• Stavanger JUG, May 25th: Test-Driven Developing with Spring and Hibernate. I also plan on talking about Spring Web Flow for a good portion of this meeting.
• Oslo JUG, May 26th: Advanced Spring MVC, Spring Web Flow and Acegi Security.

I'll try to post outlines for my presentations in the next week or so.

Very cool search with XMLHttpRequest

From fiftyfoureleven.com, I learned about forgetfoo.com - which is doing some very cool stuff with XMLHttpRequest. Be sure to check out the calendar, comments and naked picture of Britney Spears.

While we're on the topic of cool stuff, I also learned about this cross-browser Nifty Corners component. Should we call a set of CSS+JavaScript files a component I think so, what else would you call it?

DU Wins and The Blizzard of 2005

Last night was a great game and DU has repeated as NCAA Champions! Woooo hooooo!! Nice jobs gents - we're definitely looking forward to next year's season and hope to get season tickets on the glass.

This morning, I woke up to a bunch of snow, high winds and The Blizzard of 2005. It's nothing like the Blizzard of 2003 where we got 4-8 feet of snow, but it's still pretty exciting. I snapped a few picks of what it looks like around our house.

RE: Going to work for Microsoft

You know you're good when your April Fool's joke gets picked up by a major news site.

With a fair bit of attention being given to using older Web technologies to create new Net applications, Microsoft is apparently looking to make sure it is staying up to date. The company has hired Java specialist Matt Raible to help make sure that Ajax is in Visual Studio's cupboard of tools.

Ditchnet.org: JavaScript tips and a cool Tabs Tag Library

Thanks to a post to the Struts Menu Mailing List, I discovered a nice blog about JavaScript and DHTML. Not only does it seem to have lots of good tips and tricks, but its author also has a couple of cool menu examples:

• JSP Tabs Taglib
• Nice DHTML Dropdown Menus

Nice work Todd!

Trim Spaces in your JSP's HTML

One of the annoying things about JSPs is all of the dynamic (non-rendered) parts of the page still produce line breaks. This means that if you do a view-source, you'll likely see large blocks of whitespace.

The good news is you can get rid of this whitespace if you're using Tomcat 5.5.x. Just locate the "jsp" servlet in $CATALINA_HOME/conf/web.xml and add the following <init-param>:

    <init-param>
        <param-name>trimSpaces</param-name>
        <param-value>true</param-value>
    </init-param>

I tested it and it works great. This begs the question - why isn't this on by default? Source: Struts Mailing List.

Update: JSP 2.1 adds the ability to trim whitespaces.

XMLHttpRequest & Ajax Working Examples

From the AppFuse mailing list, I learned about XMLHttpRequest & Ajax Working Examples, a site that has "code snippets and proof of concepts". Subscribed.

[Microsoft] Day 1 Afternoon

At lunch, I got to meet Scoble, which was pretty cool. He was wearing a blue Firefox shirt for those that are interested. During lunch, he and his co-worker talked about Channel 9 and what they're doing with it. Channel 9 is named "Channel 9" because this is the channel that United (the airline) uses to allow passengers to listen in on the pilot's conversations. It's supposed to be an avenue for folks to listen in on what's going on at Microsoft.

Now we're sitting in a talk titled Developer Community Outreach Efforts. The speaker is named Sanjay. He's the VP of Worldwide Developer Evangelists, of which there are around 1000. Sanjay believes that MSDN is way too large. It does have a lots of interop and migration content for those that are interested.

Sanjay's trying to get ideas from us on what they can do better. The general feeling from the room seems to be "why should we help you", "what's in it for us" and "why do you care now, but not before". It's a tough room for sure. I don't seem much point in this whole talk. A lot of folks are telling this guy what he (and Microsoft) can do to become better to be better citizens to the programmer community at large. A lot of the conversation is centered on accepting open-source and providing a clearer message about the platform (should be inclusive, not exclusive).

SQL 2005 and the Developer

Now we have a guy (missed his name) that's talking about how SQL Server 2005 will allow you to expose web services directly from your database, without IIS involved. Apparently, it exposes queries and stored procedures as web services using a native Windows DLL.

Ben asked about benchmarks for SQL 2005, specifically against MySQL and PostgreSQL. The MS guy says that these vendors will need to do the "standard" TCP benchmarks, and do the comparisons there. We all know that SQL Server would get their asses kicked, and that's why they don't do any direct comparisons. While we're on the subject of SQL Server, why are most SQL Server databases so screwed up? In my experience, SQL Server DBAs tend to be over-optimization freaks that are stored-procedure happy and don't know much about making a database application-friendly. Maybe it's because all you need is a SQL Server DBA Certification to get the job - and your knowledge is based on a book, not experience.

Next topic: Access. Access is not going away. "SQL Express" is supposedly the target replacement for Access. It's throttled to prevent users from using it for a full-blown database. "You can never write a bad query for SQL Server." This is a direct quote, and the guy's reasoning is because the optimizer will change the query to be performant. Sounds like a bunch of hoo-ey to me.

Today, you can write extended stored procedures in C++ with SQL Server. This code is not sandboxed, and can pretty much to whatever it wants. In SQL 2005, you can do this with C# and use VS.NET to write the code and debug it. Apparently, they have a whitepaper on SQL CLR vs. ADO.NET and when to use one over the other.

Product Development Process with Iain McDonald (Director, Windows Server)

Iain is from Australia, which naturally makes him fun to listen to, just because of his accent. The purpose of this talk is to explain how they do things. Cross-org at Microsoft means that that development is spread across 7 businesses, each organized under own leadership with individuals p&ls.

• Business Solutions
• Home & Entertainment
• Information Worker
• Mobile & Embedded Devices
• MSN
• Server & Tools
• Windows Client

Each group has a lifecycle model that they try to follow. Microsoft has thee different stages: Product Definition, Product Development and then Product Servicing. I'm willing to bet their product development cycle follows the waterfall approach (confirmed: "How agile are we? We suck."). Actually, this brings up something I heard last night from one of the Microsoft Evengelists. Apparently, each developer has two QA folks that write tests (read: code) against their code.

Suite of Project Tools

• Feature Inventory Tool: an inventory of features and their dependencies, tracks when the features will merge into the main branch.
• Checkpoint Express: tracks all compliance throughout the project, requires sign-off prior to product being shipped.
• Basics: list of fundamentals that product is expected/required to meet, examples include performance and manageability.
• Change Management: uses an infopath form with links to the feature inventory tool and bug tracking database (product studio).

Iain admits that security in 2000 was an afterthought and the security guys were seen as some mangy dogs over in the corner. Bad RAM causes 20% of Windows crashes - who knew?! Bad RAM on OS X has certainly affected me in the past. I couldn't upgrade to Panther b/c I had 3rd party RAM in my PowerBook.

Microsoft is in a competitive battle against other companies, not the free world. No corporation in their right mind is going to download and install a free version of Linux - most are going to buy a distribution from companies like Red Hat or Novell. Iain claims that there's no way you can install Linux (at a corporation) for less money than Windows Server. It sounds to me like MSFT is willing to give you some discounts on Windows Server if you're thinking of buying Linux.

Break time. I'm definitely bored, but happy to have some time to work on AppFuse. Some guy asked me in the hall why I haven't asked more questions. I told him because I don't develop for Windows. For the most part, none of this stuff matters to me.

Windows Architecture

Now we're listening to two guys talk about Windows and how it's developed. Windows XP and Windows 2003 Server are two separate code bases. It's a nightmare to maintain b/c they have to patch one code base and the other one as well. Longhorn is componentized, so it should be easier to build client, embedded and server products. Someone asked about legal vs. technical reasons behind the componentization. Apparently, it's all for technical reasons, and they have to separate Windows Media Player for the EU, but that's about it. 40% of blue screens are from device drivers, and Longhorn has done a lot to handle this and reduce crashes.

This talk centered on XAML, WinFX and Longhorn - what they are, what they do and when they're scheduled for release. <Yawn/> While it has been a boring day (for me) technically, I do have to admit that the speakers have been great. They're dynamic and enthusiastic, which is more important IMO than good technical content. They also seem to be very open (as a whole) to ideas and criticisms. I think I'm just a bad audience member.

OK - here's something that's interesting. We're talking about IE 7 and its features. The top priorities are to stop spyware, fishing and any other security issues. #2 is tabs and #3 is CSS compliance. These priorities are based on user feedback and sound like good choices to me.
