As I’ve written before, shepherding cron on our shared UW hosting systems is one of the most interesting aspects of my job. I had a question today from someone who noted that they had @reboot for some mysql.starter scripts, and */5 or */15 for others. Here’s my response: The */5 (every five minutes) and */15 (every 15 minutes)… Read More

The fine folks at Mozilla have released a nifty tool called thimble which allows you to learn and experiment with HTML and CSS in a very user-friendly way. You get a code editor on the left side of your screen and a live preview on the right. Nifty! https://thimble.webmaker.org/en-US/ If you want to just mess around,… Read More

tl;dr: Running cronjobs with scp fails. Use “/usr/local/bin/scp” instead.

This short syntax… Read More

If you’re working on updating or rewriting a production site, it may be useful to have a mod_rewrite rule that will automatically send all traffic–except IPs you specify–to a maintenance page. This will let you communicate to your users while still allowing you and your staff to work on the site unhindered. In this case,… Read More

In light of recent support questions, I’ve added two new entries to our web publishing troubleshooting page. Highlights include: iWeb Cannot Directly Upload to public_html/student_html Folders Apple iWeb does not properly handle symbolic links and cannot directly upload to your public_html or student_html folder. This is actually an issue I’ve been tackling with for a… Read More

We’ve offered support for website access restrictions by NetID for quite a long while, and have fairly extensive documentation about how to implement this for many different scenarios, including by UW Groups and registered students in courses. One thing that you may not know is that you can also explicitly exclude NetIDs using the “not” directive.… Read More

Not too many people know about this, but UW-IT provides backup and recovery capabilities for files stored on the Uniform Access clusters, including web publishing. You can view more information about this here: http://www.washington.edu/itconnect/email/backup.html Note that this does not reliably back up active MySQL databases while they’re writing data. Refer to the this documentation for information… Read More
