@vancha That's a cool extension! I have never seen your Github page before 😅 You have some interesting projects 👍

The last days were very productive and PicPlanner is now able to calculate and present the time and azimuth of Sunrise and Sunset, the time of the blue hour and golden hour and the end and beginning of the dark night. The elevation of the sun is also visualised in a plot. I will do the same for the milky way in the next few days.

@vancha Yes, it is! :) And only a few lines of code are necessary :)
Thanks a lot!

Still experimenting with the user interface. At least my plots scale now as I want them to.
But it will still take some time until this app looks nice 😅

@vancha I also think that the last days were quite productive but there is still a loooong way to go 😅
The UI needs a lot of work until other people can use it 😅

It looks like a red rectangle... But it is a red rectangle that took me a whole day to program because I had to figure out how to plot something with Cairo inside of a GTK Box element that is not visible at the time of creating the plot... But now I understand how Cairo works 😅 I furthermore added my own formulas for calculating the position of the sun and the formulas for calculating the position of the milky way are now working correctly.

I am working on my GTK app PicPlanner again.
I had an error in my calculations which I did not understand so I started to check all my formulas again and calculated every value by hand. In the last calculation, I saw that I used a "wrong" constant which I was using half a year ago for a specific test and forgot to delete.
Only took me four hours. Nice! 👍

As mentioned in this forum post, the dimensions are 153 x 75 x 15.5 mm.

However, the final thickness is still not known but I guess it doesn't change anymore.

@peja Manjaro is the Arch Linux for people with a life outside of Linux 😅

@aircan @agx The BM818 is only missing two frequency bands that are sometimes used in Germany but not very often. This is band 28 (700 MHz) and band 32 (1500 MHz). But these bands are not very common.

Oh thanks! No I haven't seen this pdf yet. Looks interesting because it is a different approach like the ones I have seen until now. I have some books which I use for calculations furthermore I am a physics student which helps. However, the calculations are often numeric fits to measured data which makes it hard to follow where some formulas come from. This pdf is a good example that different people sometimes receive different values. I must check which formula is the most precise :D

@vancha I didn't knew that rust is that difficult in combination with GTK. In C everything is a pointer and you just have to pass them over and every thing works fine :D

It's an app for photographers who want to know when and where the sunrise and sunset is, where to find the milky way at night and so on. There are apps for Android and iOS but not for Linux and I need this app to use the L5 as daily driver. I am not that far at the moment but I want the basic functions to work until end of the year :D

@tomek
Oh thanks a lot! I have seen that he has also a Cairo tutorial. That could be quite useful for my app :D

@vancha
Haha difficult question.
I don't use Glade I write the UI files manually and I like this much more.
Writing the C code is a bit tricky but some gnome projects are written in C and I often look how they solved some problems. Purism has some examples written in C which helped using libhandy correctly. But at the moment I have not much time for programming so I will give an update once I have more experience.
But until now I am really pleased. I haven't had unsolvable problems until now.
