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.

 

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.

Web page testing tool

You can use the WBox HTTP testing tool to stress test servers and apps... 

% wbox http://localhost clients 4

0. 200 OK    9939 bytes    22 ms
...

...or obtain splitted timing information... 

% wbox digg.com timesplit 1
WBOX digg.com (64.191.203.30) port 80
0. 200 OK    44134 bytes    1326 ms 
       [0] 0-4095 -> 728 ms
       [1] 4096-8191 -> 254 ms

       [3] 12288-16383 -> 17 ms

 

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...
