Free Portlets

You are looking for some source of free portlets? I assure you that you are not going to get many. What's  more, if you got some, you probably would not be able to deploy on your server. Most of the portal servers are not compatible to each other. You can not deploy IBM WebSphere portlets to Oracle Portal Server and so on. Most of the portal server and not fully compatible with JSR 168, the interoperability standard for portlets.  Yes, You will think yourself lucky reaching to POST (Portlet Open Source Trading Site) website. But alas, you will not find many of portlets there. Anyway you can start with few portlets there and soon we hope to see more portlets.

Here is a list of Portlet Catalog for your server. 

POST (Portlet Open Source Trading Site) - JSR 168 http://portlet-opensrc.sourceforge.net/
IBM WebSphere Portal Catalog http://www-306.ibm.com/software/genservers/portal/portlet/catalog/
Oracle Portal Catalog http://portalcatalog.oracle.com/
BEA Weblogic Portal Catalog http://dev2dev.bea.com/products/wlportal/psc/index.jsp
Jetspeed Portal Catalog http://jakarta.apache.org/jetspeed/site/catalog.html


Ofcourse you can find some more portlets on open source portal products like eXo and Liferay etc.. But the process is a tedious one. At present there seems no option other then to check your portal vendor.

The list is not any way complete. But I didn't get sufficient time to research on it. Please let me know about the missing resources. I'll include those in the list.  

UPDATE Nov. 27, 2004: We have setup a free portlet repository from where many portlets can be downloaded. You can also upload your portlets there.

Web Clipping for Portals goes Mainstream

Lack of good web clippers (aka URL scrappers) in the market obstructs quick portal adoption. Web Clipping is one of the fastest methods for integrating existing applications with the portals. Though nearly all portals come with web clipper tools/ portlets but most of them lack the professional touch. Kapow and Clickmarks are two such companies in the market whose products are quite advanced in comparison to out-of-box web clipping portlets provided with most portals. Yesterday's announcement by Kapow Technology for the release of version 6.0 of "RoboSuite Web Integration platform" will definitely boost this market. Kapow Press Release

Firebase upgraded properties are not yet supported in Google Analytics App

Image
Recently I saw a message in Firebase Console to upgrade my Firebase property to Google Analytics property. Such properties are called Google Analytics App + Web properties in GA after upgrade. The primary benefit for upgrading the property that I see is that we can see all Firebase Analytics data in Google Analytics. Google Analytics is a tool that we all have used for years and it is slightly easier for me. I am also more comfortable doing analysis using Google Analytics than Firebase Analytics. On top of that we also get benefit of third party integrations like AdWords (now Google Ads) integration if we get all the data from Firebase Analytics into Google Analytics. So, I upgraded my Firebase property to Google Analytics property. The was a pleasant experience to see all Firebase Analytics data in Google Analytics in the format that I understand much better. But soon I realized that there is one important part missing. On The Go, I use Google Analytics App to get a quick glance of
