phpBB image upload

In the morning I tested image upload in a phpBB forum I installed recently. I could upload a small photo as an attachment, but a larger one failed. So I configured the board settings to accept attachments of maximum 10MB. But now I got an HTTP error.

The error log of the Nginx web server showed a client intended to send too large body message. To fix this, I logged in and changed to the root account using /bin/su -. Next, I added the following line:

client_max_body_size 10M;

to the http section of /etc/nginx/nginx.conf and reloaded the server using systemctl reload nginx.

Next, I changed one setting in /etc/php/7.3/fpm/php.ini and added another one. Those settings are as follows:


Finally, I restarted php7.3-fpm as follows:

systemctl restart php7.3-fpm

Note that I use php7.3-fpm on Ubuntu 18.04 LTS because the version that (still) comes with it, PHP 7.2, comes with a php-xml package that prevents phpBB version 3.3 from working correctly. See this how to for instructions.


I remember when mosh first came out and thinking "that sounds like a great idea, maybe I'll set it up sometime" and then never getting around to it. Several times over the years I've thought similarly, but it never seemed worth it. A week ago a coworker asked if there were good tools for handling remote terminal use over laggy internet connections, and I suggested mosh. They really liked it, which then had me feeling silly for never trying it, and got me to actually do it. So: I'm typing this over mosh, and it's excellent! I should have done this years ago.

A humble guide to database schema design

Having a good database schema design is crucial for building applications that will need to scale in traffic and complexity. If you happen to do a bad design choice you will see that it takes a lot of effort to stop the pattern from propagating to your backends’ services and controllers, and finally to your frontend.

So there is a need to be able to evaluate if a database design is better than another.

But what does good mean when we are talking about design?

Chromatopelma cyaneopubescens drinking

In the evening I saw my Chromatopelma cyaneopubescens grooming itself on top of a piece of coco peat that I keep moist to provide a humid section to its otherwise dry container.

I used a dosing syringe to moisten the piece of coco peat a little more and saw the tarantula lower itself to the substrate; it was taking some of the moisture.

Soon after it returned to its "house": a few small twigs that it has covered in some webbing.
