One of the most useful Portal apps is Paperless. Especially in countries like germany, where paper still plays a big role in everyday life, Paperless can help you stay on top of your documents and keep your desk and shelves clean. After optimizing my setup for the last few weeks, I have arrived at a point I would consider (almost) ideal. In fact, it is almost fun to scan and organize documents now. Let me walk you through it.
The Portal ecosystem is more than the software that runs on the Portals themselves, it also consists of a bunch of administrative functions. Among others things, they
Until now, these tools were accessed using a command line interface, but with increasing complexity I decided that it is time for something graphical.
There is the saying "Eat your own dog food", which means that you should use the products that you create. So the new graphical interface became a brand-new Portal app. And it really shows the simplicity Portal can provide if used correctly.
When developing a piece of software, the best way to make steady and sustainable progress is to work in small and self-contained increments. Each change should have a clear scope that is easy to reason about, to test, and to roll back if needed. Side effects should be avoided as much as possible. With the latest update, I did the opposite of that.
Recently, we were made aware of some smart home appliances that use MQTT to talk to a backend in order to publish data or receive commands. This backend can be freely configured, it just needs a MQTT broker.
It has been some time since our last update here on Patreon. For one thing, we have been busy with lots of smaller tasks - both technical and regarding business development - that do not really warrant a blog post. Some of them made it into our newsletters though. But another reason for the long silence is the next big feature which was a particularly tricky and time-consuming one: peer-2-peer communication.
This is a big one! Since from the start, we told everyone that Portal is in an early prototype stage. Your data is not safe, and it could get lost at any time. Technically, this is still the case, but now it is possible to download a full backup of all of your data whenever you want.
⚠️ This feature is not backward-compatible. Your current Portal must be deleted, and you need to recreate it. Write us as soon as you are ready.
Most apps that you install on your Portal need to persist data in some way. There are currently two ways they can do that: a) they request a database on the Postgres instance that is running on the Portal or b) they mount a part of the Portal's filesystem.
Running Apps on Portal is realized through docker-compose. When you install an app, the docker-compose.yml that contains all apps is rerendered and the process restarted. This causes docker-compose to pick up the new app and to pull it and start it.
However, until recently that meant that every app you have installed is running all the time. This limited the number of installed apps severely as the bottleneck was the Portal's RAM - 1GB with the current setup.
⚠️ If you own a Portal, restart it now, and it will upgrade itself. (Use the settings menu on the top-right.)
When we first designed the app store, we focused on building something that works quickly. It was always meant to be a first shot that would be extended or replaced at some time. We now felt compelled to address this task.
We are continuously working on bringing more apps into our app store. But since we are using apps that were originally made for self-hosting, we often need to make some tweaks. In particular, we want the user to be able to open an app after installation without the need to go through a registration or login form. Each Portal is mainly a single-user platform so that would be quite confusing.
