Will You Sponsor Me For A 100km Ride for Refugees Fund Raising Event?
September 17th, 2006I’m posting this to you to ask for your help because, this year on October 14th I am going all the way and riding full 100kms in the third annual Ride for Refugees fund raising event. I am looking for sponsors to make it all worth it. I am training for the challenge as I have never ridden that far but with God’s strength, he will carry me to the end. This cycling event is held each fall near Elmira and I am joining a growing group of cyclists who are raising support and awareness for refugees being served through International Teams Canada
I volunteer at our Welcome Home facility here in Kitchener/Waterloo and getting to know the refugees there has been very eye opening. The challenges involved with a 100km ride dwarfs in comparison of the challenges faced by a refugee. Imagine in a moments notice, force to leave everything you have and know to travel the refugee highway in hopes of a new future.
The event goal is $150,000 and I am looking to raise my share of that good goal. This year my personal goal is to raise $1000 and any amount you give will help reach or exceed it. Please help me reach my goal and help these people, in giving you too will ride with me that day.
Would you sponsor me?
There are over 35 million refugees in the world. Many are coming to Canada and they need support as they adjust to our Canadian way of life. Imagine snow for the first time. Imagine if the letters all ran backwards to what you were familiar with reading. Imagine being alienated from your friends and family. They need our support and International Teams (www.iteams.ca) has been serving refugees for over 25 years.
Don’t hesitate to sponsor me today!

Unix Cron
August 11th, 2006Introduction
cron is a utility that you can use to schedule and automate tasks. By defining items in the cron table, called crontab, you can schedule any script or program to run on almost any sort of schedule.
For example, run a program each day 5 minutes after midnight on mondays, wednesdays and fridays. Or schedule something to run every five minutes, or once a month.
Basics
Each user has their own crontab, the scheduled scripts run as that user take this in account with regards to permissions. To edit the crontab use the following command:
$ crontab -e
You can list what your currnet crontab is using the
following command:
$ crontab -l
Crontab Format
The following is the format entries in a crontab must be. Note all lines starting with #are ignored, comments.
# MIN HOUR MDAY MON DOW COMMAND
5 * * * * echo 'Hello'
| Item | Definition | Valid Values |
|---|---|---|
| MIN | Minute | 0-60 |
| HOUR | Hour [24-hour clock] | 0-23 |
| MDAY | Day of Month | 1-31 |
| MON | Month | 1-12 OR jan,feb,mar,apr … |
| DOW | Day of Week | 0-6 OR sun,mon,tue,wed,thu,fri,sat |
| COMMAND | Command to be run | Any valid command-line |
Examples
Here are a few examples, to see what some entries look like.
#Run command at 7:00am each weekday [mon-fri]
00 07 * * 1-5 mail_pager.script ‘Wake Up’
00 07 * * 1-5 mail_pager.script ‘Wake Up’
#Run command on 1st of each month, at 5:30pm
30 17 1 * * pay_rent.script
#Run command at 8:00am,10:00am and 2:00pm every day
00 8,10,14 * * * do_something.script
#Run command every 5 minutes during market hours
*/5 6-13 * * mon-fri get_stock_quote.script
#Run command every 3-hours while awake
0 7-23/3 * * * drink_water.script
Special Characters in Crontab
You can use an asterisk in any category to mean for every item, such as every day or every month.
You can use commas in any category to specify multiple values.
For example: mon,wed,fri
You can use dashes to specify ranges.
For example: mon-fri, or 9-17
You can use forward slash to specify a repeating range.
For example: */5 for every five minutes, hours, days
Special Entries
There are several special entries, some which are just shortcuts, that you can use instead of specifying the full cron entry.
The most useful of these is probably @reboot which allows you to run a command each time the computer gets reboot. This could be useful if you want to start up a server or daemon under a particular user, or if you do not have access to the rc.d/init.d files.
Example Usage:
# restart freevo servers
@reboot freevo webserver start
@reboot freevo recordserver start
@reboot freevo webserver start
@reboot freevo recordserver start
The complete list:
| Entry | Description | Equivalent To |
|---|---|---|
| @reboot | Run once, at startup. | None |
| @yearly | Run once a year | 0 0 1 1 * |
| @annually | (same as @yearly) | 0 0 1 1 * |
| @monthly | Run once a month | 0 0 1 * * |
| @weekly | Run once a week | 0 0 * * 0 |
| @daily | Run once a day | 0 0 * * * |
| @midnight | (same as @daily) | 0 0 * * * |
| @hourly | Run once an hour | 0 * * * * |
Miscelleanous Issues
Script Output
If there is any output from your script or command it will be sent to that user’s e-mail account, on that box. Using the default mailer which must be setup properly.
You can set the variable MAILTO in the crontab to specify a separate e-mail address to use. For example:
MAILTO=”admin@mydomain.com”
Missed Schedule Time
Cron does not run a command if it was missed. Your computer must be running for cron to run the job at the time it is scheduled. For example, if you have a 1:00am scheduled job and your computer was off at that time, it will not run the missed job in the morning when you turn it on.

CronniX is a Aqua (Mac OS X) front-end to the Unix utility cron. I haven’t used
this but looks pretty cool. If you prefer a GUI interface and have a Mac, check
it out. (Freeware)
