Quartz: pause all running jobs

We have a requirement to pause quartz jobs while complex changes are being made to our webapp.Use Scheduler.pauseAll() to pause them. This will pause future triggering of jobs but it doesn't stop jobs which are currently running.

To find if any jobs are running currently, size of scheduler.getCurrentlyExecutingJobs() list can be checked. Check this in a simple while loop till size is zero.

Scheduler.resumeAll() is the counterpart of pauseAll().

Technical fun

Message on Mac OSX 10.4.x machine, first time when "sudo" command was used.
Last line is a classic from spiderman and got added after spiderman movie was released. Earlier Mac OSX sudo commands just gave #1 and #2 warnings. Apple's engineers certainly have humor !

Technical fun

Bug in stuffit (for Mac OS X). Too many hours to unzip ?? Classic signed/unsigned integer bug.

When Google says n results are found, these are approximate.
It doesn't find all the results, in this particular case, after moving to page three, all the results were exhausted, although earlier estimate was upto four pages.

Drawing styles - Movie posters from south India.

Same scene can be drawn in various styles. Over time, I have collected samples of various styles. Attached are samples.

Look at the image highlighted with a red arrow. Notice the usage of few colors and wide spaced black lines.

Portable and free apps

One of the pains of windows software is portability ! Install the app, it makes changes to registry, uninstall it, leaves registry bloated. And if you wish to backup data, you'll need to manually figure it out.

Portable Apps is a collection of popular applications which carry data along with application. It has minimum installation and no need to backup (registry, Application data, My documents, etc). And it is FREE.
