Are you avid #miniatures painter? Do you enjoy #warhammer40k or #warhammer? Maybe #warhammerpainting is your thing?

Or do you like smaller games like #bloodbowl, #mordheim or #necromunda? Maybe naval warfare or ancient battles is what you're interested, or #wargames in general?

Join #miniaturemonday. Post a #miniature you're proud of or are currently working. Enjoy banter with other painters and connect with people interested in #miniaturepainting.

Introduction: I'm Tuukka, and like tinkering with code and little toy soldiers (mostly 15mm ancients). I try to pick up reading again, preferably something that isn't code related. Currently that something seems to be #ancient #history.

When time permits, I work on Hy (http://docs.hylang.org/en/stable/) a cool #lisp build on top of #python. It has super friendly community and it was my first step into lisp.

I have a blog (https://engineersjourney.wordpress.com/), where I try to post now and then.

next time someone says purely functional language can't be used for anything, I'll going to bring up Parmenides and Heraclitus. It won't be an useful discussion, but might be highly entertaining

listening podcast about history of philosophy and wondering how eleatics relate to programming, especially immutability

Hacker Public Radio is fun concept. There are tons of episodes on various topics and if you want episode on specific topic, you can record it by yourself.
#hpr #podcast

another podcast recorded. It's getting easier, but I still find it funny to record my own voice. And I find it really hard to keep talking, instead of having long pauses when I think of something new.

I keep finding new ways to mess up and die in Way of the Samurai 3. Last night it was getting a stone lantern thrown at me.

going to try and make another podcast episode and this time actually prepare some sort of plan, so I don't just ramble.

wrote down some thoughts about planetary orbits and #haskell in my #blog https://engineersjourney.wordpress.com/2018/06/29/planetary-orbits-and-haskell/

Got it up to geocentric coordinates (right asension and declination). I think I'll call it mostly done at this point and look for something else to tinker with next

curd soap for cleaning brushes, yes or no?

I have been using water only for cleaning brushes (natural and artificial hair) after painting with acrylics and eventually bristles start to separate

been playing with planetary orbits again and I think this is one of those cases where strongly typed language shines. No need to be worried that I mix different coordinate systems as types enforce consistency.

@tuturto code in the morning, painting in the evening with some more code if I have energy left. little bit computer games over the weekend.

@tuturto it's nice to program in Haskell again, even if it's just a toy program for my own amusement

tackled some problems with code and at least intermediatery results are correct. Have to go through rest of the calculations and find the error still.

horses still at the same state as week ago, but maybe I finally manage to do something about them later in the evening.

Still need to crack some coding stuff for work though.

checking online, I'm getting completely incorrect results

not surprised at all though :D

*Planets> calcEqCoords Mercury $ d 2018 6 23 8.75
EqCoord Mercury 0.6813815 0.68425024 0.4660814

At least I'm getting results, needs some testing of course before I know if that really works and gives correct answers
#haskell #astronomy

hm.. transposing ecliptical coordinates to equatorial requires knowing of obliquity of the ecliptic, which depends on the date.

I wonder if this means that I should carry date with the coordinates to make sure sure there isn't mistakes with it along the way?

This seems to do the trick
Now that I can calculate Mercury's location in ecliptic coordinates, it's time to start transforming them to different coordinate system.
Eventually hoping to get to the point where I can point shiny spot in the sky and say "yup, that's Mercury"
#haskell #astronomy

If Orbit is type class with two parameters, how should I write the type signature for the function and the function in itself?
