What Hacker News says?

  1. What kind of collision detection do you use? I was inspired by your games to try something similar for the latest Ludum Dare: http://www.bemmu.com/compo/ludum/37/index.html At first I tried checking every creature for collisions against everything else, but unsurprisingly that was too slow (N^2). To reduce the checks I put each creature in a grid cell based on their position, then check for collisions only against c…

  3. Cool. But yours outputs 16-bit signed audio whereas by default /dev/dsp outputs 8kHz 8-bit unsigned audio, so it sounds a little bit different. Also, http://www.bemmu.com/music/index.html beat you to it and http://wurstcaptures.untergrund.net/music/ also does URL-formulas :). (As an aside, bemmu's is creating a 16-bit signed .WAV data from 8-bit signed functions, so it isn't doing it quite right either. Why not just…

  5. Tokushima, Japan. Not a particularly inspiring environment, besides the good beaches and view of the mountains. Non-existent developer community. Sufficiently sized city (200k) to have everything you need. Fun festivals. For our family of two adults and a baby, our living cost is very roughly $3000 / month. Biggest cost is my health insurance, second highest expense is rent, our place is $720 / month. You need a car…

  7. Hi, yes actually I tried exactly that. It cost me $60 / customer, which is over my lifetime value so I discontinued advertising there. Here's my stats from the attempt: http://www.bemmu.com/stats-from-advertising-candy-japan-on-r... Things might be different now, the page was less optimized back then. I might try again later, but I'm really hoping Reddit would just lower their minimum daily spend. Right now they hav…

  9. I started this to learn and to provide some basic source of income in addition to software, so it has worked well for that purpose. It has involved writing more software than I expected, though! Earlier posts are at http://www.bemmu.com/ with currently no easy way to see only the Candy Japan related things. I was still feeling a bit undecided where to put them, wondering if it's a good idea to expose customers to in…

  11. bemmu Hopefully you see this, unfortunately your comment is dead. Because I think your comment has value I will quote it here, please let me know if you'd like it removed.

  15. Here's my review from trying one a while back: http://www.bemmu.com/airwheel-electric-unicycle-review It was a ton of fun but I did not end up using it in real life because of the low range and unsure legal status. I still miss having one though and might buy a newer model later to give it another go, it was so much fun to ride.
