Have you ever had tasks you had to perform each morning on getting at your desk? I do. Since I reboot every day, I first used a text file I added to the All programs > Startup menu of my Windows, but it was not satisfactory, as the text file gets lost behind all my other windows anyway (IDEs, e-mails, … You get the idea.).

So, I finally took the time to program the task manager I wanted: something compact, which will not close until I have not checked all tasks, and which remains on top of other windows. Here is what I did.

## My new favorite log4j conversion pattern

log4j is a powerful logging utility for the Java programmers. Until now, I let other developers configure it. However, I was not satisfied with the configuration in my current project and took a deeper look.

# The log4j pattern

Our logs were cumbersome, always displaying the full package, which is not always interesting. Dates varied from a log to another. So I looked for a standard conversion pattern I could use whenever I have to log something with log4j, and after some diving in the documentation, here is what I came up with:

# Some explanation

• %d{ISO8601} – displays the date and time in the ISO format (see earlier post about this norm).
• %-5p – the log level (such as DEBUG, INFO, WARN, …), formatted to occupy five columns (I like when things keep in line).
• %t – the name of the thread logging this line.
• %c{1} – the name of the class calling the logger (the {1} argument is there to restrict the number of packages displayed; {2} would display one package level before the class name, {3} would display two package levels, … and %c without the brackets would display the full package and class names).
• %M – the method.
• %L – the line number.
• %m – the message to log.
• %n – begin a new line.

There you are.
