WebSphere Portal v6.5.1

WebSphere Portal v6.5.1 has been released.

  • Enable: CR9TQML
  • Extend: CR9SYML

 

Getting links

To copy link locations for a left navigation table of contents on an IBM infocenter page, expand left navigation, mark and copy into MS Word. Links and titles will be saved.

 

Computer for Seniors

A great new computer for seniors, You Can Do It Computers. Big buttons. Big scrollbars. Locked down. Simple interface. Super easy to operate.

 

linklist.sh

As test, running....

nohup sh ./linklist.sh > linklist.log 2>&1 &
...from...

/var/www/tech

...generating links to Two-phase commit protocol.

linklist.sh is usually run deeper down the file system, as the script is not optimized for speed and takes a while to traverse the hundreds of thousands of files on the system. This run is being timed.

 

Project Management

While not a project manager, I can't help but offer some ideas to improve the current dismal state of the practice.

Basic principles:

  • Project management, and project documents, should be web-based.

  • Every task should be a link to supporting material. Ideally, every single detail should be a link to more detail.

  • On top of the project repository, like a beacon in the night, there should be a search engine.

  • The project site should contain one, and only one, canonical copy, of each project document.

Most of the dozens of large IT shops I've had the privilige to work for, unfortunately, do not follow these principles. IT professionals and executives, many working for companies that produce web artifacts, who surf the net every day, for reasons that probably are both venal and banal, think it perfectly appropriate to negotiate their project's treacherous shoals using network drives and standalone MS Office documents.

When working a project plan, the efficient cashiering of each task is essential to finishing on time. Discreet delays add up like compound interest. Vital information found in 15 seconds via a search speeds the project. If information requires ferreting out with several days of emails and phone calls, the prospects for the project finishing on time diminish rapidly.

Maintaining a web-based, hyperlinked, and searchable project plan requires a little more thought than just throwing Microsoft Office documents out on a network drive. Not much, really, but enough that the incurious cannot make the conceptual leap to producing, rather than just consuming, web-based material.

Use Word for desktop publishing only, and not as a standard document template. Use Excel for number crunching, not as a notepad. Learn the 20 HTML tags required to get started, or find yourself a WYSIWYG editor that generates clean HTML. Capture every detail as early as possible, and make sure that each detail is fully explained by hyperlinking to supplemental information. Your projects will finish on time.

 

This site

  1. Uses scripts to automatically add hyperlinks for all key words and phrases.
  2. Strips out redundant tags, so pages are lean and load fast.
  3. Places, in context, supplemental material from my own and other people's experiences.
  4. Adds white space and makes fonts scalable.
  5. Strips out useless verbiage. For example, removing every occurrence of the word "easy".
  6. Dozens of other more or less idiosyncratic tweaks.

Syndication and jcr:uuid

When importing content or component items into your Web Content Management system, either though xmlaccess, or custom scripts that employ the WCM API, pay attention to how jcr:uuids are created. If, for example, the content you are importing is referenced by existing components, you need ensure that referential integrity is maintained.

 

JCR Explorer and XPath

Been running a lot of XPath queries in JCR explorer these days, trying to fix some syndication issues.

For example, getting error...

Could not save item with id DepRef(id:121212121 type: com.aptrix.pluto.site.SiteArea nonDraft:true draft:false purged:false parentId:919191919 timeStamp:123 stateUpdate: false versions:null moved: false) because it could not find its parent.

...means parent uuid on subscriber does not match parent uuid on syndicator. To verity, in JCR Explorer, run the following queries on both systems...

//element(*, ibmcontentwcm:siteArea)[@jcr:uuid = '121212121']
//element(*, ibmcontentwcm:siteArea)[@jcr:uuid = '919191919']

You will undoubtedly find both uuids on syndicator, but not subscriber. This will be the case even if site areas show as existing on both machines from within the authoring portlet on the subscriber.

One way to fix...

  1. Delete site area child and parent on subscriber
  2. Edit site area on syndicator and then save, to give item a fresh time stamp.
  3. Re-syndicate

Personalized portlet

One key thing to note about personalization in WebSphere Portal v6.1 is that for Web Content Management items you can implement most functionality using the Personalization component mapped to rules. You don't need to use Rational Application Developer personalization features to create personalized content. RAD comes into the picture if you want to personalize non-WCM content. For WCM content, you probably do not need to fire up RAD.

Signal vs. Noise

Scientific research conducted by Walker Reading Technologies, a small Minnesota startup that has been studying our ability to read for the last ten years, has concluded that the natural field of focus for our eyes is circular, so our eyes view the printed page as if we are peering through a straw.

Here is an example...
