Going through the list of 15 suggessions to improving usability in open source software the main problem is that too many cooks spoil the broth, A good user interface requires as much thought as does the software architecture. There have been cases where a requirement for a better user interface has required significant changes in the code across the stack because usability was not thought about upfront.

The web has grown in 10 years from 26 million unique URLs to 1 trillion unique URLs. This makes it a very challenging task for Google to crawl all the pages. The amazing part is that they do this a couple of times a day to keep their search engine uptodate.

I was experiencing some discomfort while using the standard wired optical mouse that shipped with my PC, so I recently purchased the Logitech MX Revolution wireless mouse. The mouse includes a Li-on battery so that you don't have to change batteries every 6 months. The mouse felt very comfortable in my hand since it is a little wider than a standard mouse. One interesting feature that anybody who multi-tasks a lot of software on their PC would appreciate is a scroll button on the left hand of the mouse that can be used to quickly switch between applications. I highly recommend this mouse!

HP has release a new Touchsmart computer that is an all in one like the iMac, one of the interesting feature is that it ships with 64 bit version of Windows Vista. With 4GB memory becoming quite cheap we may start seeing more PCs ship as 64 bit with more than 4GB memory.

An excellent article on Domain Driven Design with a Java example, it emphasizes capturing your domain into POJO and not creating fat objects that mix implementation specific features such as caching with the domain code.

Recently I helped somebody setup a Job to update some tables from a remote database. So I thought I would give some example here on how to create and track jobs using the Oracle Job Scheduler begin drop table test2; create table test2 (f1 varchar2(10)); dbms_scheduler.drop_job('JJ'); dbms_scheduler.create_job( job_name => 'JJ' ,job_type => 'PLSQL_BLOCK' ,job_action => 'begin insert into test2 values(''abc''); end; ' --,job_action => 'null;' ,start_date => systimestamp ,repeat_interval => 'FREQ=MINUTELY; INTERVAL=1' ,enabled => TRUE ,comments => 'Job.'); dbms_scheduler.set_attribute('JJ', 'logging_level', dbms_scheduler.logging_full); dbms_scheduler.set_attribute('JJ', 'job_priority', 1); end; -- Run Job nowbegin dbms_scheduler.run_job('JJ'); end; select * from user_scheduler_job_log where job_name = 'JJ'; -- Job History select * from user_sched...

This is a very good artcile about how to manage a small open source project . A lof of the information also applies to a closed source project, such as documenting the features. In our division we have an internal wiki that I use extensively in documenting all the cool features of our software so that when I am asked about a feature I can just point them to the Wiki.
