People who followed my Hoshi OSdev-ing adventure know by now that I started working on the operating system (actually, at that time my plan was to write a bootloader) in 2015, and my development setup was very different at that time, and that it changed several times. In this article I’ll “reveal” a bit of the Hoshi history, describe my current OSdev setup and document it for future iterations.

I forgot that someone e-mailed me a while ago asking me what are the icons on the right side of Hoshi’s taskbar (it’s actually the System Bar) and if I want to “reveal” some information about them, so here is a small walkthrough.

The first applet retrieves the Bitcoin Price Index JSON from Coindesk and displays it on right click. It’s the first applet I did for Hoshi and it prompted the creation of the JSON-parsing library in libhoshi, so I’m pretty attached to it, even if it’s useless to me.

The second applet retrieves weather data from api.openweathermap.org via a similar JSON file and shows the current temperature in the System Bar and some more weather info on right click. The city, API key, unit format are all configurable from a small popup window (and a config file). This applet is obsoleted by the Weather Widget that resides inside the Widgets Bar, I’m keeping it enabled for now so the System Bar looks more active.
