I guess the OSM community is more defaulting to developing for other open platforms because that's what we mostly use ourselves and can test/run the code on, but iOS is in the making: Pinned ticket "iOS - Planning": htt

It's a hundred times less polished than rebound (that readme looks seriously cool!), but in 2021 I also wanted to toy around with orbital mechanics / gravity and couldn't find a quick and easy simulator so I made this to run

GRPN for anyone else who doesn't know it: http://lashwhip.com/grpn.html What I meant to say is that, if one uses a featureful calculator like qalc, then you get unit conversion included without needing two separate uti

I don't understand, is that what you used originally to come up with your original comment (this one: https://news.ycombinator.com/item?id=37483892 )? If so, that is surprisingly similar to what I ended up with when try

You never use a calculator?

by lucgommans 3y ago
:D What calculation did you use though? Like some formula or is there a web utility for this, for example?

A white dwarf's density is apparently around 1e9 kg/m³. Olympic swimming pools at 50m*25m*2m * 1e9kg/m³ would have a weight of 2.5e12 kg. As a sphere, the radius is (solving: volume_of_sphere = 4/3×π×radius³) $ qal

Rather than teaching a separate utility, I would recommend qalc which has unit conversions built in :) $ qalc -t 100km/h / 0.956s to gee 2.9629132 gees (where -t is for terse mode; by default it expands unit abbreviat

Protip: no need for a dedicated unit conversions utility, this awesome calculator has it built in: $ apt install qalc $ qalc > 100 km/h / 0.956 s to gee (100 * (kilometer / hour)) / (0.956 * second

Very interesting website! I submitted it[1] because it's quite the eye-opener for me (e.g. blob tracking is new to me, and if you click on the cell, it shows you PoC test code!) and I had missed its previous submission two years ago. B

Omg, it works! Why does this work? It doesn't work on Firefox ~4 on Windows XP with a real Flash player installed, nor does it work on MSIE8 on that system. I tried on the original site as well as on a custom file that embeds just that

They link to a collection called "Software Library: Flash". How do I add something there? I've uploaded gravityrunner years ago and recently (45 days ago, the site tells me) figured out how to activate the emulator for this s

Sort of. KSP teaches you rocket building and how precious fuel is. You need to invest a lot of time to get to the stage where you transfer between planets. You also can't just pick up the resident star, give it a whack, and see what ha

Recently at an OSM meetup with the local government in Aachen (Germany), they mentioned that some imagery they shot was deemed too invasive and only used internally. I thought that was 10cm, but now checking what is available, looks like I

Indeed, something like 25cm or better is typically shot from airplanes. I don't remember what the physical limit is for image quality given a reasonably sized spy satellite (iirc it's around the 20cm mark), but commercially at lea
