Certificate headaches

Creating and managing PKI certificates is always tricky. A small list of what went wrong today when following my own guide for importing your own Oracle Enterprise Manager certificate:

Tag clouds

It is quite hard to find a good tag cloud for Drupal 7.

I had hoped to find a views based solution, as that would be the most flexible. Or, at least, it should be able to filter on content type (as I have one vocabulary for two content types).

Virtual Debian

I have been trying to get old versions of Debian to run as virtual machines. Most of it works without trouble, but there are some things you should be aware of, if you want to try it yourself.

My host is a Debian Wheezy machine running Linux kernel 3.11 and Qemu/KVM 1.1.2, using Virtual Machine Manager (virt-manager) 0.9.1.

Releasing old software

After a long, long time, I decided to release a new version of psiconv. That is tooling I wrote between ten and fifteen year ago. In those days I owned a Psion 5 (and later the upgraded model, the Psion 5MX), a small PDA with keyboard running EPOC (also known as EPOC32, a precursor of Symbian).

Images are just files

Just a quick one this time: in Drupal, the image field type is based on the file field type. That means that if you are looking for a way to use IMCE to upload images, the IMCE for File Field module will just do the job.

Creating a poor man's blog

Sometimes you have to write your own Drupal modules. Sometimes you need some heavy weight module. But often, you can fit several smaller modules together to get what you want.

Things I did not know about MySQL

Did you know that MySQL can join at most 61 tables in one query?

Did you know that table data is by default stored as latin1 with the  latin1_swedish_ci collation?

Things I did not know but should have - as I encountered both issues the same day.

Drupal profile_permissions

Sometimes you encounter a bug which makes you... not so happy.

On the Unquendor site, which is still Drupal 6, I use profile fields extensively. These are basically attributes of users. Not only names and addresses, but also things like visits to events and even a member's payment status is kept in this way. Of course, not everyone is allowed to see all fields, let alone edit them. The profile permissions module should enforce the proper policies.

Drupal project part two

Previously, I complained about the instability of the Drupal project module. The last days, I have been working on and off to analyze where the problems are and to solve some of them. It is now possible to see the list of releases on the project page and most pages do not return errors anymore.

VPN woes

Yet another random wifi network to connect to - this time in a small cottage in Slovenia. It actually allows access to internet, allows me to setup a VPN, so all seems well. Except for one little thingie: for some reason, it blocks outgoing SMTP traffic.

Well, no problem, there. I want to mail from my laptop, and it delivers to the mail server on my server. No problem there, if I route the traffic through the VPN, right? Wrong. After setting up the VPN it is still not working.
