Butterflies often congregate at dried-up puddles to gather salt and minerals. This is one of several groups seen at Texas Falls.

I recently upgraded our library’s Koha installation to 19.11 (from 19.05), and at the same time upgraded the operating system from Debian 8 to Debian 9. This created a problem with the “Stage MARC records for import” feature in Koha. I could upload the file, and using ssh I could see the file in /tmp. But then Koha would complain that the file did not exist when it tried to import it.

The cab of an abandoned backhoe. You can tell from the depth of the leaf litter next to the wheel that it’s been there a long time.

I was asked to install Linux on four newish HP notebooks with 17 inch screens. These machines came with Windows 10, so it was necessary to do a dual-boot installation. The three major problems with these HP machines were:

• getting the machine to boot from a Linux Mint bootable USB thumb drive
• a Realtek wi-fi device whose driver was not built into the Linux kernel
• Secure Boot preventing the Realtek driver from loading

Our library has enabled the cart feature in the Koha OPAC, which allows patrons to create a list of books they’re interested in. Some patrons have used the “Send” feature of the cart, which allows them to send the cart to an arbitrary email address. But there have been several problems with this, such as bad email addresses causing the emails to be redirected to the sysadmin (me).

I decided to suppress the ability to send the cart by hiding the “Send” button. In Administration / Global system preferences, edit the OPACUserJS preference to look like this:

$(document).ready(function(){
    $('#userbasket .toolbar a.send').hide();
});

If there already is a “ready” function in OPACUserJS, add the “hide” line shown above to that function.
