Legitimate, Useful Subversion For Search Engine Marketers

Wednesday, April 9th, 2008

Often, the hardest part of any search engine optimization or marketing campaign is getting changes made to the website. Figuring out what to do is often easier than convincing all the stakeholders—including marketers, IT departments, web developers—to take the necessary actions, and coaching them along the way as they apprehensively take baby steps forward. As search marketers, we also need to test web sites. We always want to tweak things and see if we do better, and if not, we go back and try something else. We also work in teams.

Success in search marketing campaigns often depends on the nitty-gritty details of execution. That is why I have spent a lot time investigating different tools that help automate our work flow and promote teamwork. One of my favorites goes by the apt and clever name of Subversion.

Subversion, also known as SVN, is free open source software that provides revision control of source code, web pages and other documents. Revision control means that all current and past versions of each file are saved, with notes about who edited them and what they did. If a bold change goes terribly wrong, a few clicks restores a prior version of the site. Revision control also permits multiple editors to work on the same files without wrecking each others’ work. After updating their local files, everybody can be confident that they have the latest versions. Most edit conflicts are automatically resolved.

Revision control software is much more efficient than ad hoc arrangements such as emailing files back and forth, or using Dreamweaver’s FTP synchronization feature. A web server is for serving web pages, not for syncing files. Our Subversion server provides much faster data transfer, and Subversion tracks changes line by line, so it only transfers the lines that have changed, rather than whole files, saving even more time.

Here are a few situations where Subversion helps most:

Eliminating the IT bottleneck. When a website is hosted in-house, the IT department often does not provide web server FTP access for security or management reasons. They usually want to control all changes, rightly so, because they are responsible. However, IT staff are busy or may lack experience in search optimization. It normally takes three times longer to teach a client how to fix their own website than to just do it for them. IT departments like Subversion because it saves them time, and provides an audit trail, as well as a reliable backup copy of the website in case the server ever suffers a meltdown. When a client is on Subversion, even if I do not have FTP access, I can still grab the latest copy of their website, make the necessary edits and commit them to the repository. Then I ask the client to pull updated files from the repository, review the changes on a development server, and release them to the live site. Verifying and releasing a website update is faster, and requires fewer skills, than editing.

Replacing content management systems. One of the selling points for content management systems is that clients can edit their own website, especially when multiple people are involved. Content management systems usually introduce design rigidity, causing website improvements to take longer and cost more. When websites have a catalog with thousands of parts, or a shopping cart, a content management system is obviously necessary, but when a website is just brochure-ware, content management systems can be a poor investment and an impediment to search marketing. With Subversion, we allow clients to use Dreamweaver or Contribute to edit sites themselves. Everybody on the team uses Subversion to coordinate changes, and if somebody wrecks the site, we can roll back to the prior version. With Subversion as a safety net, the editing process goes faster, and more people can have access.

Delegating work.When managing staff, I need to see what they are doing, and be able to jump in on a moment’s notice when help is needed. Having direct, immediate access to the source code makes it easy to fix a bug in the middle of the night when a client complains. I do not need to tell everybody “sync your files” or risk having them erase my change. Subversion handles that automatically. If a client emails a request, any employee can help themselves to the latest code from the repository, and make edits. Without Subversion, having more than one person working on a site risks confusion.

Backups and using multiple computers.My nightmare scenario used to be losing my computer. What if it breaks? I’ve switched most of my business management tools to cloud computing, such as Basecamp and Freshbooks. But I still have a few important files on my machine, plus all the websites I am working on. Subversion provides secure cloud storage for all those critical files. Subversion makes both of my computers interchangeable. I can right click on any folder to quickly synchronize files from the repository.

Subversion has two components: a server that stores sets files (called modules), and a desktop client for accessing the server. The Subversion server can be installed locally, or on a remote machine. I prefer to use a hosted service such as CVSdude, where they handle all the details for a nominal monthly fee. Tortoise SVN is the most popular Subversion client for Windows. Tortoise asks for the URL of the repository, a userid and a password. All files in a module can be checked out, edited as needed, and then changes are committed. Tortoise integrates into Windows’ File Explorer. Folders show a green check mark if they are current, or a red X when they have been changed.

In 2007 Forrester Research called Subversion “the sole leader in standalone software configuration management (SCM)”. When something that good is free, you think most people would use it. However, most search marketing professionals I speak with have never heard of Subversion.

Sun’s Java iPhone Port Faces Obstacles

Tuesday, April 1st, 2008

Posted by Charles Humble on Mar 31, 2008 11:59 PM

 

Within 24 hours of Apple unveiling the iPhone SDK, Sun Microsystems announced their intention to port the Java ME JVM to Apple’s iPhone and iPod Touch devices. In a video announcement Eric Klein states that he sees no reason why the JVM would not work on the iPhone:

“We’ve spent the last 24 hours feverishly pouring through all the information that Apple made available about this SDK and we’re really excited that Apple has decided to open the iPhone and iTouch (iPod Touch) to third party development. One of our original visions for Java was to allow the developer community to create amazing content and applications for as many devices across the world as possible and the iPhone is an important platform in that regard.”

When Sun made its announcement a number of astute bloggers and forum posters pointed out two major issues that seem to preclude Sun’s Java port. The first is a clause in the license agreement:

“An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. No interpreted code may be downloaded and used in an Application except for code that is interpreted and run by Apple’s Published APIs and built-in interpreter(s).”

The second appears at first glance to be a technical limitation in the SDK. According to Apple’s official iPhone Human Interface Guidelines (available from the Apple iPhone Dev Center, login required) only one iPhone application may run at a time, and third-party iPhone applications will not be able to run in the background:

“This means that when users switch to another application, answer the phone, or check their email, the application they were using quits. It’s important to make sure that users do not experience any negative effects because of this reality. In other words, users should not feel that leaving your iPhone application and returning to it later is any more difficult than switching among applications on a computer.”

This is presumably not strictly a technical limitation - the iPhone runs the same kernal as Mac OS X which supports multiple concurrent processes. The iPhone itself can clearly multitask (otherwise it couldn’t, for example, ring when you were using Safari with it) so this restriction is most probably imposed to limit the amount of RAM consumed by third party background processes. It seems reasonable to speculate that Apple could therefore allow chosen third party developers the ability to run their applications in the background. However it seems quite unlikely that Apple would provide Sun such access. For one thing being able to install and Run Java ME applications on the iPhone and iPod Touch would make it harder for Apple to restrict distribution to their store as they intend, and for another Apple’s relationship with Java seems to have become increasingly negative over the last few years. Contrast Steve Job’s comments at a keynote at JavaOne 2000 in which he said:

“We want to bring Java back to the desktop in a really big way. I’m here today to personally tell you we are working hard to make Mac the best Java delivery vehicle on the planet. The biggest thing we are doing is we are going to bundle Java 2 SE into every single copy of Mac OS X [the upcoming Macintosh operating system] that we ship later on this year.”

with remarks he made last year to the New York Times:

“Java’s not worth building in. Nobody uses Java anymore. It’s this big heavyweight ball and chain.”

Eric Klein issued a further statement last week stating that Sun would like to talk to Apple if there are conditions blocking Sun’s intentions:

“Our announcement was based on our excitement to build a JVM for the iPhone and the iPod Touch, as well as our assessment of Apple’s publicly available information on the SDK and related business terms. If there are clauses in the iPhone beta SDK license agreement that potentially limit third party application distribution, then these are items that we want to have a positive discussion with Apple about. Sun and Apple have an ongoing relationship around Java SE on Mac OS X and we look forward to further discussions with Apple about a JVM for iPhone and iPod Touch. Sun definitely plans to deliver a JVM for iPhone and iPod Touch if at all possible!”

It will be interesting to see if Sun provide any more details during JavaOne.

Sun’s MySQL Will Continue Oracle Relationship

Tuesday, April 1st, 2008

Despite a new owner and the potential for more competition in the future, MySQL and Oracle will continue to work together.


When MySQL AB was bought by Sun Microsystems, some knowledgeable observers said the first thing Sun would do is make MySQL free of its dependence on Oracle.

MySQL incorporated the InnoDB transaction storage system as part of its database system, then Oracle acquired its Finnish parent company, Innobase Oy, in October 2005. “Look for Sun to do more and more to make MySQL free of any third parties,” said Raven Zachary, open source analyst with the 451 Group, in an interview at the Open Source Business Conference in San Francisco.

But Zack Urlocker, the executive VP of products, who supervises both engineering and marketing at MySQL, says such independence is still viewed as unnecessary inside Sun. Urlocker appeared on a panel on the state of the open source database market. Seated nearby was Ken Jacobs, VP of product strategy at Oracle.

MySQL’s strength has been in its ability to serve Web pages, and many Web applications are built with MySQL as the database of choice in the background. Oracle aspires to be the database of future applications as well, including Web applications, and it’s conceivable the two eventually will come into more direct competition.

But Urlocker says that doesn’t mean MySQL can’t keep using InnoDB. “We’ve always had a very good relationship with Oracle,” he said after the panel concluded.

“It’s absolutely a fact. We’ve always had a very good relationship,” affirmed Jacobs, one of the original employees of Oracle, who helped establish Oracle with the federal government from its new Washington office in 1981.

MySQL isn’t ready to announce anything yet, but the way Urlocker and Jacobs exchanged meaningful glances, it was as if to say they’re ready to sign a multiyear continuation of their agreement.

Meanwhile, another third-party piece of software on which MySQL used to depend, the SolidDB for MySQL that was under the sponsorship of IBM, has been pushed off to SourceForge. Dhiren Patel, IBM’s community relations manager for the overall SolidDB project, announced that IBM had acquired SolidDB in December for its in-memory database, technology that will help it compete with Oracle TimesTen.

“This in-memory technology, and not Solid’s open source offering, was the key driver behind IBM’s acquisition. As a result, I regret to inform you that, effectively immediately, we will not be continuing further development on SolidDB for MySQL,” he wrote March 3, six days after Sun completed the MySQL deal.

The open source community around SolidDB for MySQL will be free to continue work on the project, and the developer forums and bug tracking have been migrated to SourceForge as well, Patel noted.

Urlocker said both Jacobs and Charles Phillips, Oracle’s president, have assured him of continued, unfettered access to InnoDB. MySQL, initially developed as a read-only database, gets its key transaction handling characteristics from InnoDB and SolidDB for MySQL.

Oracle bulks up .NET tools

Wednesday, June 6th, 2007

By Tony Baer 

At Microsoft’s TechEd conference in Orlando, Oracle is announcing beta versions of a couple existing tools that help .NET developers work with Oracle databases, plus a new tool for writing applications that store web session data in Oracle databases. 

Oracle is adding a new feature to Oracle Developer Tools for Visual Studio .NET that allows developers to generate code by dragging and dropping database objects onto ASP.NET web pages. It also adds the ability to back up Oracle scripts that are part of .NET apps into popular source code control tools, including Microsoft Visual SourceSafe, CollabNet Subversion, or Microsoft’s Visual Studio Team System (VSTS) Foundation Server. 

Oracle has also automated support for custom data types in Oracle with a wizard that helps you map data without having to drill down to SQL or write in C# or Visual Basic.NET. 

Oracle’s Data Provider for .NET, which helps developers gain access to data inside Oracle databases, is adding support for mapping custom classes from C# or VB.NET into custom data objects. 

Additionally, Oracle is introducing a new .NET offering, called Oracle Providers for ASP.NET, which lets you store session state in an Oracle database. This feature is useful for tasks such as preserving access (a form of single sign on) to a web application without requiring repeated logins. 

Oracle is supporting eight data provider types that form attributes of a web user’s session access. The most popular are likely to be membership in an authorized user group, individual user role, and profile (which covers the attributes of a user relating to their access privileges). Other providers include session state for shopping carts, web events, personalization, cache dependency, and site maps. 

Each of these tools are being released as free beta versions. Oracle has not decided when they will be ready for general release.
