Re:Rocket and Space Technology by Robert Braeunig on Friday June 26, 2026 @09:52AM (#48686665)
When designing the procedural rocket engines in Juno: New Origins (formerly known as SimpleRockets 2) this site was one of the resources I kept coming back to while learning the underlying math.

It's also just a beautiful example of the old web at its best. Simple layout, no distractions, lots of substance. Truly a gem for anyone interested in rocket science.

Are you referring to the Chinese Room? I've always had an issue with that argument. Instructions are immutable, but neural networks certainly are not.
Re:How much do indie PC devs make, anyways? on Saturday January 31, 2015 @01:54AM (#8976111)
This is what I have found. I started indie game dev a back in 2009, and I'm finally to the point where I'm making a very comfortable living, but by no means a millionaire. However, having a small company with some fellow devs is now in the realm of possibility, which is a long-time dream of mine.

Edit: My games are mostly mobile. I am really excited about the figures he posted for Steam. I just got one of my games greenlit on Steam (SimpleRockets) and I hope I can sustain further development on it.

Great job handling the traffic spike by still giving us links so we can check out your game.

You might like the book "Nothing to Envy: Ordinary Lives in North Korea." There's quite a few jaw dropping stories from people who defected from NK. It's such a mysterious country, I am completely fascinated by it.

Very impressive, especially for a weekend "hack". What did you write the site in?
Re:GoDaddy is "suboptimal" for hosting WordPress on Wednesday October 24, 2012 @12:04PM (#4693512)
It wasn't covered in the blog post, but it is also interesting how slowly WordPress performed compared to DotNetNuke. I never felt there was a performance problem with my web site until I moved from DNN to WP. I suppose it could also be GoDaddy's MySQL servers vs their SQL Server servers. Maybe their MySQL servers are bogged down.

Edit: added a missing word.

Re:Microsoft Open Sources their Entity Framework ORM on Thursday July 19, 2012 @02:33PM (#4267425)
I've used it on a few projects. I have never used NHibernate, so I can't really compare them, but I really like EF. I don't have a great deal of SQL experience, so I'm much better at writing queries with LINQ methods and prefer it over SQL. It's great having strongly typed entities and the intellisense is awesome, but that's probably true with any ORM.

Ask HN: Does this web app already exist?

from the ask-hn dept.

With the allergy season in full swing, I'm absolutely miserable, but I've realized that I'm not entirely sure what I'm allergic to. Is there a website that I can enter my email address and zip code and let it figure out what I'm allergic to? It could give me an e-mail survey at night, asking me to rate my allergies on a scale from 1 to 10 for the day. It could also ask about other symptoms,...

Re:Why haven't we cured cancer yet? on Monday April 09, 2012 @01:38PM (#3818140)
I disagree that we should not allow such a thing if it existed. I think humans are a bit past the need for biological evolution. Technology can provide us with the ability to adapt to new challenges and environments, and can do so much more quickly.

Yesterday I climbed from 51 to 36 in the US app store and received 4,119 downloads.
Re:Show HN: My Newest iPhone Game - Dummy Defense on Tuesday March 20, 2012 @10:22PM (#3732781)
I pop up a dialog asking for their e-mail after 3 app loads. I'm not actually sure what the rate is (signups per impression). I have surprisingly little analytics in my apps, I really should incorporate some of that. Do you know of any good services for that?
Re:Show HN: My Newest iPhone Game - Dummy Defense on Tuesday March 20, 2012 @05:30PM (#3731728)
I actually used a home-made framework that I have been kludging together since my first app, BridgeBasher. Back then, Cocos2D and Unity3D weren't as awesome as they are today. It worked out well though, having my own framework really lets me dig into the nuts and bolts and change any aspect that I need.

I have an email list of about 80k subscribers that I've accumulated from my other apps. About 28% have opened, and about 25% of those who opened actually clicked the link.

Yesterday I clocked 3879 downloads and landed at #52 in the charts. I'm not sure how many downloads I've gotten today.

I decided on the $0.99 price point because of the large e-mail list.

Good idea. What subreddit would you post something like this on?

Show HN: My Newest iPhone Game - Dummy Defense

from the show-hn dept.

The game is Dummy Defense. It launched yesterday and is currently at #41 top overall in the US app store. I did some heavy promotion yesterday with a large email list, and FreeAppADay is promoting my other app, SimplePhysics, which is driving quite a few sales. I'd be glad to hear your feedback about the game as well as answer any questions regarding the development or marketing efforts.Here's...

I feel responsible for derailing this thread, but FWIW samstave, I did chuckle at your comment.
