In my web development career, I have countless times needed to look at Apache logs to figure out or find out about problems with sites, monitor activity, or for various other purposes. I’ve used command line tools to help with this, often looking for strings and counting occurrences. Since I recently needed to create a command string to count unique IP’s connected to a given string in the logs, I thought I’d post about it and a few related useful commands.Continue reading post "Looking at Apache logs with command line tools"
The Ubuntu / Debian
unattended-upgrades package has an option to automatically reboot as needed when it upgrades packages. It will do this without user input, at a chosen time. However, it doesn’t allow for any conditions beyond need and time. I found a need for more nuance recently, so I had to disable the built-in functionality and set up my own script on a cron job.
For Ubuntu servers, I use the
unattended-upgrades package to automate keeping the system and packages up to date. I recently noticed some of Cogneato’s servers showing packages needing to be updated for multiple days. When I looked in
unattended-upgrades.log (in folder
/var/log/unattended-upgrades/), I found the message “WARNING Package something has conffile prompt and needs to be upgraded manually”. Basically, there was a change to a configuration file and it didn’t know how to handle it.

I finally gave in because the cost made sense and I feel it will give me more freedom and ease of doing things that require data.Continue reading post "I’ve got home internet again"
I had to make a toggle switch widget for work recently. I had not done one before, having used built in or custom check-boxes for that purpose. My boss thought the switch would better fit a simple “form” that turns off and on a single setting though, so I made one.Continue reading post "HTML + CSS toggle switch"
I made a simple
bash backup script for the newer MySQL database servers at Cogneato.
I recently had the need to take a name from a form submission and use it as the display name of the “From” address of an email sent through PHP’s
mail() function. For an address like
Toby Example <firstname.lastname@example.org>, the display name is the
Toby Example part.
Some presumed bots figured out the reCaptcha (version 2) we protect forms with at Cogneato.Continue reading post "reCaptcha solved by bots?"
