UCron - Userspace Cron

Question

http://blog.barrucadu.co.uk/2008/11/ucr … pace-cron/
I found myself in need of running a script every hour, and get the result reported to me with notify-send. I found no easy way to do this with regular cron, as notify-send needs to be run from within an X session (or so my limited knowledge says), so I decided to write a simple python script to run commands every minute, half hour, and hour.
#!/usr/bin/env python
import time, datetime, os
while(True):
now = datetime.datetime.now()
# Run minutely commands.
os.system("for script in ~/cron/minute/*; do $script; done")
if now.minute == 30:
# Run bihourly commands.
os.system("for script in ~/cron/halfhour/*; do $script; done")
elif now.minute == 0:
# Run bihourly and hourly commands.
os.system("for script in ~/cron/halfhour/*; do $script; done")
os.system("for script in ~/cron/hour/*; do $script; done")
time.sleep(60)
Just make the directories ~/cron/minute, ~/cron/halfhour, and ~/cron/hour, stick a call to uCron in your gnome-session (or whatever you use), and away you go!

Phew, that was a lot of stuff... browsed many examples too... and in the end it looks like the crontab was the "right" place to put that thing after all, everything else just seems like a "dirty" or overkill solution in comparison...
The only thing that still irritates me is cron insisting to write every single freaking *success* into the logs (/journal) instead of just warnings / errors. I really don't need that thing telling me: "Hi, I'm still OK! " every other minute -.- but there does not seem to be an option (other than installing a syslog-daemon capable of "blacklisting" the entries as a workaround) to shut it up... which was the reason why I first thought that scripts which are to be executes so often don't belong into the crontab.
Hmm... not sure what to do yet. Is there anything else I should know / read before I make up my mind and stop looking for a better solution to this?
Which cron do you use? I have dcron installed and it has a log level setting - see man crond
